Cluster headaches present with unilateral severe headache that may be associated with ipsilateral cranial autonomic symptoms including| lacrimation, rhinorrhoea, ophthalmic injection, and occasionally, Horner syndrome (ipsilateral miosis, ptosis, and facial anhidrosis).

Human breast milk composition changes with the progressive age of the infant. Breastmilk produced for a preterm baby often has a higher caloric content than breastmilk for a term baby. After the production of colostrum in the first days of life, the milk continues to mature. by week 4-6 milk can be considered fully mature. The average calories found in mature breastmilk are about 70kcal/100ml

The baby needs more oxygen saturation which could be attempted by increasing the mean airway pressureAfter initial resuscitation and stabilization, the following should be the ventilator settings used:Rate: 30-40/minutePeak inspiratory pressure (PIP) – determined by adequate chest wall movement.An infant weighing less than 1500 grams: 16-28 cm H2O.An infant weighing greater than 1500 grams: 20-30 cm H2O. Positive end expiratory pressure (PEEP): 4 cm of H2O OR 5-6 cm if FiO2 > 0.90.FiO2: 0.4 to 1.0, depending on the clinical situation.Inspiratory time: 0.3-0.5 sec.After 15 to 30 minutes, check arterial blood gases and pH.If the PaO2 or the O2 saturation is below accepted standards, the FiO2 can be raised to a maximum of 1.0. If the PaO2 or O2 saturation is still inadequate, the mean airway pressure can be raised by increasing either the PIP, PEEP, inspiratory time or the rate, leaving inspiratory time constant.If the PaCO2 is elevated, the rate or peak inspiratory pressure can be raised.

The presenting features and the surgical site provided in the clinical scenario are highly suggestive of ipsilateral hypoglossal nerve injury.Note:Three cranial nerves may be injured during submandibular gland excision.- Marginal mandibular branch of the facial nerve- Lingual nerve- Hypoglossal nerveHypoglossal nerve damage may result in the paralysis of the ipsilateral aspect of the tongue. The nerve itself lies deep to the capsule surrounding the gland and should not be injured during an intracapsular dissection. The lingual nerve is probably at higher risk of injury. However, the effects of lingual nerve injury are predominantly sensory rather than motor.Thus, the most appropriate answer is the hypoglossal nerve.

The most important test recommended among the given options is the measurement of creatine kinase levels.The child presents with a gross motor developmental delay, and multiple investigations can be undertaken to confirm the diagnosis. However, the clinching point in the given clinical scenario is the presence of a positive Gower’s sign.Gower’s sign is an excellent screening test for muscle weakness, which is typically observed as an early clinical feature of Duchenne muscular dystrophy (DMD).Creatinine kinase measurement is an easy and rapid test to aid in the diagnosis. Early diagnosis has significant implications not only for the child but for the family, particularly for genetic counselling. DMD is an X-linked recessive disorder, with an abnormal gene at the X chromosome at the Xp21 locus. It is a progressive degenerative muscular condition where muscle fibres are replaced by fat and fibrosis (i.e., become dystrophic).

Cyanotic congenital heart disease (CCHD) is a common cause of neonatal morbidity and mortality. They can be classified as CCHD due to:- Right-to-left shunt, associated with the decreased pulmonary flow, e.g., tetralogy of Fallot (TOF), pulmonary atresia, right-sided hypoplastic heart,- Right-to-left shunt, associated with the decreased aortic flow, e.g., left-sided hypoplastic heart, interrupted arch, severe coarctation| – Bidirectional shunt, e.g., TGA, DORV, TA, etc. Eisenmenger syndrome is not a neonatal CCHD| rather it develops later in young adulthood secondary to various CHD.

The type of significance test used depends on whether the data is parametric (can be measured, usually normally distributed) or non-parametric.
Parametric tests:
Student’s t-test – paired or unpaired*
Pearson’s product-moment coefficient – correlation

Non-parametric tests:
Mann-Whitney U test – unpaired data
Wilcoxon signed-rank test – compares two sets of observations on a single sample
chi-squared test – used to compare proportions or percentages
Spearman, Kendall rank – correlation.

The outcome measured is not normally distributed, i.e. it is non-parametric. This excludes the Student’s t-tests. We are not comparing percentages/proportions so the chi-squared test is excluded. The Mann–Whitney U test is a nonparametric test of the null hypothesis that it is equally likely that a randomly selected value from one sample will be less than or greater than a randomly selected value from a second sample.
This test can be used to investigate whether two independent samples were selected from populations having the same distribution.

The incubation periods of disorders is extremely important to diagnose, treat, prevent or attenuate a disease. Chickenpox: 7-21 days. Whooping cough: 10-14 days. Hand, foot and mouth disease: 2-6 days. German measles: 14-21 days. Mumps: 14-18 days.

A not immunized patient with a clean wound requires an immediate vaccination against diphtheria, tetanus and polio, according to the Green Book of Immunisation against infectious disease. (The Green Book has the latest information on vaccines and vaccination procedures, for vaccine preventable infectious diseases in the UK.)

Coxsackie viruses are a group of RNA viruses with over 20 serotypes| depending on specific viral characteristics, these serotypes are further divided into groups A and B. Infection is associated with a wide range of symptoms, which are dependent on the exact serotype. Hand, foot, and mouth disease (HFMD) and herpangina are commonly caused by group A coxsackie viruses, while pleurodynia and myocarditis are caused by group B coxsackie viruses. Both groups may cause viral meningitis, conjunctivitis, or flu‑like symptoms. Diagnostic procedures and treatment should be tailored to the specific disease manifestation. Coxsackie A :HerpanginaHand, foot, and mouth diseaseCharacteristics: highly contagiousClinical presentationGeneral symptoms: fever, reduced general conditionSkin/mucosaMaculopapular and partially vesicular rash on the hands and feetOral ulcersDiagnosis: clinicalTreatment: symptomaticPrognosis: almost always self‑limiting

Unconjugated bilirubin is conjugated to glucuronic acid in the hepatocyte. Conjugated bilirubin passes into the enterohepatic circulation and the bilirubin which evades this system is metabolised by bacteria, primarily in the large intestine, to urobilinogen, then stercobilinogen and eventually oxidised to stercobilin. Stercobilin gives faeces its brown colour.

ADH primarily acts on the collecting ducts.Other options:- The juxtaglomerular apparatus is the site of renin production.- The proximal tubule conducts isosmotic reabsorption of about 60% of sodium chloride and volume. Most of the glucose, amino acids, potassium and phosphate are absorbed here.- The loop of Henle is the site of 25% of sodium reabsorption. Active Chloride transport provides the basis for the counter current multiplier aiding urinary concentration.- The distal convoluted tubule is impermeable to water and acts via active sodium chloride absorption to dilute urine.

Identify babies as being more likely to develop significant hyperbilirubinemia if they have any of the following factors:- gestational age under 38 weeks- a previous sibling with neonatal jaundice requiring phototherapy- mother’s intention to breastfeed exclusively- visible jaundice in the first 24 hours of life.

Answer: Inflammatory bowel diseaseThe inflammatory bowel diseases (IBDs), including ulcerative colitis and Crohn disease, are chronic inflammatory disorders of the gastrointestinal tract most often diagnosed in adolescence and young adulthood, with a rising incidence in paediatric populations. Inflammatory bowel disease is caused by a dysregulated mucosal immune response to the intestinal microflora in genetically predisposed hosts. Although children can present with the classic symptoms of weight loss, abdominal pain, and bloody diarrhoea, many present with nonclassical symptoms of isolated poor growth, anaemia, or other extraintestinal manifestations.Colorectal Carcinoma (CRC) is rare in patients less than 20 years of age.

The most probable cause for the patient’s symptoms is intussusception.Intussusception is a condition in which part of the intestine folds into the section next to it. It most commonly involves the small bowel and rarely the large bowel. Intussusception doesn’t usually require surgical correction. 80% of cases can be both confirmed and reduced using barium, water-soluble or air-contrast enema. However, up to 10% of cases can experience recurrence within 24 hours after reduction, warranting close monitoring during this period.Other options:- Enteric duplication: a duplication cyst could give all these features, although it may contain sufficient gastric epithelium to produce a positive Meckel’s scan. However, this is comparatively rare. – Meckel’s diverticulum: Scintigraphy has poor sensitivity making the possibility of a bleed from a Meckel’s diverticulum a genuine differential for this patient. However, considering the presence of features of bowel obstruction in the patient, a Meckel’s diverticulum bleeding and obstructing at the same time would be a rare phenomenon. – Midgut volvulus: It is also a plausible differential in this patient. However, for the given age group, a midgut volvulus is relatively uncommon compared to intussusception. – Acute appendicitis: While it is true that appendicitis can present acutely with a palpable mass and bowel obstruction, it rarely presents with rectal bleeding.

The organisms most likely to cause post-splenectomy sepsis include:- Streptococcus pneumoniae- Haemophilus influenzae- MeningococciEncapsulated organisms carry the most significant pathogenic risk following splenectomy. Hyposplenism:It may complicate certain medical conditions where splenic atrophy occurs or maybe the result of medical intervention such as splenic artery embolization and splenectomy for trauma. The diagnosis of hyposplenism is difficult, and while there may be peripheral markers of the splenectomised state (e.g. Howell-Jolly bodies), these are neither 100% sensitive or specific. The most sensitive test is a radionucleotide labelled red cell scan.It dramatically increases the risk of post-splenectomy sepsis, particularly with encapsulated organisms. Since these organisms may be opsonized, but this then goes undetected at an immunological level due to loss of the spleen. For this reason, individuals are recommended to be vaccinated and have antibiotic prophylaxis.Key recommendations:- All those with hyposplenism or prior to an elective splenectomy should receive pneumococcal, Haemophilus type b and meningococcal type C vaccines. These should be administered two weeks before or two weeks following splenectomy. The vaccine schedule for meningococcal disease primarily consists of a dose of Men C and Hib at two weeks and then a dose of the MenACWY vaccine one month later. Those aged under two may require a booster at two years. A dose of pneumococcal polyvalent polysaccharide vaccine (PPV) is given at two weeks. A conjugate vaccine (PCV) is offered to young children. The PCV is more immunogenic but covers fewer serotypes. Boosting PPV is either guided by serological measurements (where available) or by routine boosting doses at five-yearly intervals.Annual influenza vaccination is recommended in all cases- Antibiotic prophylaxis is offered to all. The risk of post-splenectomy sepsis is highest immediately following splenectomy. Individuals with an inadequate response to pneumococcal vaccination are another high-risk group. High-risk individuals should be counselled to take penicillin or macrolide prophylaxis. Those at low risk may choose to discontinue therapy. All patients should be advised about taking antibiotics early in the case of intercurrent infections.- Asplenic individuals travelling to malaria-endemic areas are at high risk and should have both pharmacological and mechanical protection.

Deficiency of 21-hydroxylase, resulting from mutations or deletions of CYP21A, is the most common form of Congenital Adrenal Hyperplasia, accounting for more than 90% of cases.Females with mild 21-hydroxylase deficiency are identified later in childhood because of precocious pubic hair, clitoromegaly, or both, often accompanied by accelerated growth and skeletal maturation (simple virilizing adrenal hyperplasia)Diagnosis of 21-hydroxylase deficiency: High serum concentration of 17-hydroxyprogesterone (usually >1000 ng/dL) and urinary pregnanetriol (metabolite of 17-hydroxyprogesterone) in the presence of clinical features suggestive of the disease| 24-hour urinary 17-ketosteroid levels are elevated

The boy needs re-hydration due to his full thickness burn so IV fluids is the next most appropriate step. The greatest loss of plasma occurs in the first 12 hours after burn injury. The plasma loss then slowly decreases during the second 12 hours of the post-burn phase, although extensive leakage can continue for up to three days (Ahrns, 2004). Optimal fluid replacement during this period is essential to ensure cardiac output and renal and tissue perfusion. Usually, 36 hours post-burn, capillary permeability returns to normal and fluid is drawn back into the circulation. Burns of more than 15% of surface body area in adults and of over 10% in children warrant formal resuscitation.The Parkland formula for the total fluid requirement in 24 hours is as follows:4ml x TBSA (%) x body weight (kg)|50% given in first eight hours|50% given in next 16 hours.Children receive maintenance fluid in addition, at an hourly rate of:4ml/kg for the first 10kg of body weight plus|2ml/kg for the second 10kg of body weight plus|1ml/kg for >20kg of body weight.End pointUrine – adults: 0.5–1.0 ml/kg/hour|Urine – children: 1.0–1.5ml/kg/hour.

While the cause for Bell’s palsy is still under debate, it is observed that Bell’s palsy is often preceded by a viral infection. Bell’s Palsy:Bell’s palsy (idiopathic facial palsy) is an acute unilateral lower motor neurone palsy. It typically occurs two weeks after viral infection such as Epstein–Barr, herpes simplex, herpes zoster or mumps. A careful assessment may suggest an alternative aetiology for the acute onset of weakness, e.g. acute otitis media, Lyme disease, hypertension. Causes:In childhood, Bell’s palsy is probably a post-infectious (i.e. immune-mediated) phenomenon, while in adults, there is increasing evidence that the majority of cases follow reactivation of previous HSV infection. Management:The prognosis is generally good in childhood with full recovery in the majority. However, permanent weakness is observed in around 5%. Steroids and acyclovir may have some benefit in adults with recent onset of weakness, but the evidence of the treatment benefit is much less convincing in childhood. Exposure keratitis is an important complication and children should be managed with eye drops and taping of the eyelid at night until recovery is complete.

The most probable diagnosis for this patient would be Edward syndrome.Edward syndrome results from trisomy 18. It is the second most common syndrome after Down syndrome. 60% of cases die within 48 hours, and 90% within the first year due to apnoeas. Cardiovascular abnormalities include atrial septal defect, ventricular septal defect and a persistent ductus arteriosus. There is no association with exophthalmos, but it may occur. Right choroid plexus cysts are found on coronal imaging, and 40–70% at post mortem are shown to have multiple large bilateral choroid plexus cysts (>10 mm). These may not become pathological but usually trigger an anomaly scan. Around 1% of cases may present with only a cyst, but 4% may present with other abnormalities.Other options:- Children with the velocardiofacial syndrome have a classic facial appearance with hypertelorism, a tubular nose, a cleft lip/palate abnormality and cardiac anomalies. – Children with Patau syndrome usually present with midline defects and are less likely to have rocker-bottom feet. – Children with Treacher Collins syndrome present with abnormalities of the branchial arches and pharyngeal pouches.

The murmur of tricuspid valve regurgitation is typically a high-pitched, blowing, holosystolic, plateau, nonradiating murmur best heard at the lower left sternal border. The intensity is variable, but tends to increase during inspiration (Carvallo’s sign), with passive leg raising, after a post-extrasystole pause, and following amyl nitrite inhalation. The intensity of the murmur tends to correlate positively with the severity of regurgitation. Right ventricular enlargement may displace the location of the murmur leftward. Right ventricular failure may abolish respiratory variation. When tricuspid regurgitation is caused by pulmonary hypertension, a pulmonic ejection click may be audible. Severe tricuspid regurgitation is commonly accompanied by a third heart sound emanating from the right ventricle and best heard at the lower left sternal border. Severe tricuspid regurgitation typically produces an accentuated jugular cv wave and may produce hepatic congestion with a pulsatile liver.The auscultatory findings associated with ventricular septal defect are variable, depending on a variety of morphologic and hemodynamic considerations. The systolic murmur associated with a Roger’s-type ventricular septal defect (regurgitant jet flows directly into the right ventricular outflow tract) in patients with low pulmonary vascular resistance is a low to medium pitched, holosystolic murmur with midsystolic accentuation. The intensity of the murmur is typically grade 3 or higher.Patent ductus arteriosus produces a continuous murmur in patients with normal pulmonary vascular resistance.

The diagnosis of scabies can often be made clinically in patients with a pruritic rash and characteristic linear burrows. Definitive testing relies on the identification of mites or their eggs, eggshell fragments, or scybala. This is best undertaken by placing a drop of mineral oil directly over the burrow on the skin and then superficially scraping longitudinally and laterally across the skin with a scalpel blade. (Avoid causing bleeding.) Scraping 15 or more burrows often produces only 1 or 2 eggs or mites, except in a case of crusted scabies, in which many mites will be present. The sample is placed on a microscope slide and examined under low and high power. Potassium hydroxide should not be used, since it can dissolve mite pellets. Failure to find mites is common and does not rule out the diagnosis of scabies.

Treating persons infected with C. trachomatis prevents adverse reproductive health complications and continued sexual transmission, and treating their sex partners can prevent reinfection and infection of other partners. Treating pregnant women usually prevents transmission of C. trachomatis to neonates during birth. Chlamydia treatment should be provided promptly for all persons testing positive for infection. Treatment delays have been associated with complications (e.g. PID) in a limited proportion of women. To minimise disease transmission to sex partners, persons treated for chlamydia should be instructed to abstain from sexual intercourse for 7 days after single-dose therapy or until completion of a 7-day regimen and resolution of symptoms if present. To minimise risk for reinfection, patients also should be instructed to abstain from sexual intercourse until all of their sex partners are treated. Persons who receive a diagnosis of chlamydia should be tested for HIV, GC, and syphilis.

Exposure to excessive androgens is usually accompanied by premature epiphyseal maturation and closure, resulting in a final adult height that is typically significantly below that expected from parental heights. congenital adrenal hyperplasia (CAH) is associated with precocious puberty caused by long term exposure to androgens, which activate the hypothalamic-pituitary-gonadal axis. Similarly, CAH is associated with hyperpigmentation and hyperreninemia due to sodium loss and hypovolaemia.

Codman’s triangle is the triangular area of new subperiosteal bone that is created when a lesion, often a tumour, raises the periosteum away from the bone. The main causes for this sign are osteosarcoma, Ewing’s sarcoma, eumycetoma, and a subperiosteal abscess.

Osteochondromas, or osteocartilaginous exostoses, are the most common benign bone tumours, and tend to appear near the ends of long bones. The overgrowth can occur in any bone where cartilage forms bone, and they are capped by cartilage. They are most common in people between the ages of 10-20 years old.

HLA-DR (3 and 4) have been associated with an increased risk for idiopathic diabetes mellitus.Type 1 diabetes has a high heritability compared to type 2Identical twins have a 30-50% risk if their twin has type 1 diabetes

The progesterone is primarily responsible for preventing pregnancy. The main mechanism of action is the prevention of ovulation| they inhibit follicular development and prevent ovulation. Progestogen negative feedback works at the hypothalamus to decreases the pulse frequency of gonadotropin-releasing hormone. This, in turn, will decrease the secretion of follicle-stimulating hormone (FSH) and decreases the secretion of luteinizing hormone (LH). If the follicle isn’t developing, then there is no increase in the oestradiol levels (the follicle makes oestradiol). The progestogen negative feedback and lack of oestrogen positive feedback on LH secretion stop the mid-cycle LH surge. With no follicle developed and no LH surge to release the follicle, there is the prevention of ovulation. Oestrogen has some effect with inhibiting follicular development because of its negative feedback on the anterior pituitary with slows FSH secretion| it’s just not as prominent as the progesterone’s effect. Another primary mechanism of action is progesterone’s ability to inhibit sperm from penetrating through the cervix and upper genital tract by making the cervical mucous unfriendly. Progesterone induced endometrial atrophy should deter implantation, but there is no proof that this occurs.

Jacob is likely to be four years old as demonstrated by his activities throughout the day. Most 4 year olds are able to run well, jump and hop, but find skipping a little more difficult. They are able to brush their teeth and dress themselves with supervision, and go to the toilet alone.

The recurrent laryngeal nerve (RLN) innervates all of the intrinsic muscles of the larynx except for the cricothyroid muscle, which is innervated by the superior laryngeal nerve (SLN).Patients with unilateral vocal fold paralysis present with postoperative hoarseness or breathiness. The presentation is often subacute. At first, the vocal fold usually remains in the paramedian position, creating a fairly normal voice. Definite vocal changes may not manifest for days to weeks. The paralyzed vocal fold atrophies, causing the voice to worsen. Other potential sequelae of unilateral vocal-fold paralysis are dysphagia and aspiration.Bilateral vocal-fold paralysis may occur after total thyroidectomy, and it usually manifests immediately after extubation. Both vocal folds remain in the paramedian position, causing partial airway obstruction. Patients with bilateral vocal-fold paralysis may present with biphasic stridor, respiratory distress, or both. On occasion, the airway is sufficient in the immediate postoperative period despite the paralyzed vocal folds. At follow-up, such patients may present with dyspnoea or stridor with exertion.

Inguinal hernias are a common surgical condition in preterm male infants. Surgical repair is usually suggested shortly after birth due to a fear of incarceration or strangulation. These hernias are often indirect as they pass though the processes vaginalis, rather than the posterior wall of the inguinal canal. Recurrence of the hernia is the most common post operative complication. While other complications can occur if left un-repaired, hydrocele and testicular atrophy are not as common, neither is spontaneous resolution.

Individuals with Marfan syndrome are usually tall and slender, have elongated fingers and toes (arachnodactyly), loose joints, and have an arm span that exceeds their body height. Other common features include a long and narrow face, crowded teeth, an abnormal curvature of the spine (scoliosis or kyphosis), stretch marks (striae) not related to weight gain or loss, and either a sunken chest (pectus excavatum) or a protruding chest (pectus carinatum). Some individuals develop an abnormal accumulation of air in the chest cavity that can result in the collapse of a lung (spontaneous pneumothorax). A membrane called the dura, which surrounds the brain and spinal cord, can be abnormally enlarged (dural ectasia) in people with Marfan syndrome. Dural ectasia can cause pain in the back, abdomen, legs, or head. Most individuals with Marfan syndrome have some degree of near-sightedness (myopia). Clouding of the lens (cataract) may occur in mid-adulthood, and increased pressure within the eye (glaucoma) occurs more frequently in people with Marfan syndrome than in those without the condition.

The most probable diagnosis for this patient is Maple syrup urine disease (MSUD).Note:- Healthy new-borns have blood sugars between 3.3 and 5 mmol/L- Neonatal hypoglycaemia is glucose < 2.2 mmol/L if measured in the first 3 days of life.- Neonatal hypoglycaemia is glucose < 2.5 mmol/L after the first 3 days of life.Causes of persistent hypoglycaemia include:- Preterm- IUGR- SGA- Hyperinsulinism due to maternal diabetes- Beckwith-Wiedemann syndrome- Hypoxia at birth- Sepsis- Cardiopulmonary disease- Inborn errors of metabolism- Hepatic enzyme deficiencies- Glycogen storage disease

The most appropriate imaging modalities to be used in this child would be CT Head, C-spine and Abdomen/Pelvis and chest X-ray (CXR).The C-spine cannot be cleared, this alongside a multi-trauma presentation means a CT C-spine is indicated rather than X-rays alone. The imaging modality for blunt trauma to the chest is CXR| if this shows significant thoracic trauma, a CT chest should be considered. Other options:- CT Head and Abdomen/Pelvis with CXR and X-ray C-spine: This child is at risk of C-Spine injury following the mechanism of trauma. He had a reduced GCS, has undergone a multi-region trauma and is now intubated. NICE head injury guidelines, therefore, recommend using CT.- CT Head, C-spine and Abdomen/Pelvis X-rays: Imaging of the chest is required following blunt trauma and for endotracheal tube position.- MRI Head: If there were concerns of abnormal neurology, then spinal MRI could be considered.- Whole-body CT: It is not recommended in children in view of the high radiation doses.

The clinical picture suggests tension pneumothorax which requires immediate needle decompression.

6 month old milestones:Social and Emotional:Knows familiar faces and begins to know if someone is a stranger Likes to play with others, especially parents Responds to other people’s emotions and often seems happy Likes to look at self in a mirror Language/Communication:Responds to sounds by making sounds Strings vowels together when babbling (“ah,” “eh,” “oh”) and likes taking turns with parent while making sounds Responds to own name Makes sounds to show joy and displeasure Begins to say consonant sounds (jabbering with “m,” “b”) Cognitive (learning, thinking, problem-solving):Looks around at things nearby Brings things to mouth Shows curiosity about things and tries to get things that are out of reach Begins to pass things from one hand to the other Movement/Physical Development:Rolls over in both directions (front to back, back to front) Begins to sit without support When standing, supports weight on legs and might bounce Rocks back and forth, sometimes crawling backwards before moving forward

The boy presented with mild hypoglycaemia and should be managed at home with fast-acting carbs. He should not sleep immediately. His parents should monitor his blood glucose every hour without letting him sleep in between.

The patient is suffering from an anaphylactic reaction to the cashew nut he consumed.Anaphylaxis:Anaphylaxis is an acute, rapidly progressing, potentially life-threatening IgE mediated Type I hypersensitivity reaction.It involves the release of mediators from mast cells, basophils and inflammatory cells. It is characterised by oedematous swelling of the airway mucosa giving rise to dyspnoea and respiratory distress.The most common cause of anaphylaxis in children is a food allergy.Risk factors for death in patients with anaphylaxis include asthma, age 11+, peanut allergy, and delay in adrenaline administration.Management of anaphylaxis includes:- Resuscitation – ABCD- Remove the allergen- IM adrenaline is given at ten microgram/kg or Nebulised adrenaline 5ml 1:1,000- IV Hydrocortisone is given at 4mg/kg- pro re nata IV fluid support. – Followed by observation.

Prednisone is used for the treatment of myasthenia gravis if there is no initial response to the anticholinesterase medications. Pyridostigmine can make the symptoms of myasthenia gravis worse if used  in the initial stages of treatment. 

Primitive reflexes are central nervous system responses, many of which disappear as a child matures. Retention of these reflexes may point to atypical neurology such as in cerebral palsy or stroke. However, some persist into adulthood. The stepping reflex is present from birth and normally disappears by 6 weeks, while the moro reflex is present from birth to about 4 months. The asymmetrical tonic neck reflex disappears by about 6 months. Reflexes that persist include the head righting reflex which develops at 6 months, and the parachute reflex which develops at 9 months.

Congenital heart defects are common (40-50%)| they are frequently observed in patients with Down syndrome who are hospitalized (62%) and are a common cause of death in this aneuploidy in the first 2 years of life.The most common congenital heart defects are the following:- Endocardial cushion defect (43%), which results in atrioventricular septal defect (AVSD)/AV canal defect- Ventricular septal defect (32%)- Secundum atrial septal defect (10%)- Tetralogy of Fallot (6%)- Isolated patent ductus arteriosus (4%).About 30% of patients have more than one cardiac defect. The most common secondary lesions are patent ductus arteriosus (16%), atrial septal defect, and pulmonic stenosis (9%). About 70% of all endocardial cushion defects are associated with Down syndrome.Valve abnormalities, such as mitral valve prolapse or aortic regurgitation may develop in up to 40-50% of adolescents and adults who were born without structural heart disease.

Transient tachypnoea of the new-born (TTN) is the commonest cause of respiratory distress in new-borns and self-limiting. It can affect any new-born shortly after birth. Its most prominent feature is tachypnoea. Nasal flaring, grunting, or intercostal retractions may also be present.

Celiac disease has characteristic shortened intestinal villi. When patients with celiac disease eat products containing gluten, they are unable to absorb the nutrients due to flattened or shortened intestinal villi. The blistering rash present on the patient’s elbows strongly suggests celiac disease. This rash is a sign of the condition Dermatitis Herpetiformis which is associate with celiac disease. Therefore, it is also often called ‘gluten rash’.

A cohort study is a particular form of longitudinal study that samples a cohort (a group of people who share a defining characteristic, typically those who experienced a common event in a selected period, such as birth or graduation), performing a cross-section at intervals through time.
The relative risk (RR) or risk ratio is the ratio of the probability of an outcome in an exposed group to the probability of an outcome in an unexposed group. Relative risk is used in the statistical analysis of the data of experimental, cohort and cross-sectional studies, to estimate the strength of the association between treatments or risk factors, and outcomes.

Protein energy malnutrition often presents in two common forms, Kwashiorkor and Marasmus. Kwashiorkor is characterised by a protein deficiency with an additional inadequate calorie intake. As a result, affected children present with oedema, muscular atrophy, and their weight for age is 60-80% of the expected weight. Their cutaneous tissue is however preserved. Marasmus on the other hand is characterised by a severe calorie deficiency leading to atrophy of the muscles and adipose tissue, with weight loss being less than 60% of the normal. In both cases, if the child is not promptly rehabilitated, the malnutrition could cause irreversible damage, such as hepatic, cardiac and renal impairments.

Hyposplenism usually occurs after the surgical removal of the spleen or in pathological processes where the splenic tissue is replaced with abnormal tissue. It is often associated with diseases such as sickle cell disease, Coeliac disease, SLE and Dermatitis Herpetiformis. Myxoedema however bears no known association with hyposplenism. Patients with hyposplenism are at risk of fulminant bacterial infection.

Ideally, the test is done in the first 4 to 5 weeks, but it can be done at up to 3 months of age.The identification of all new-borns with hearing loss before age 6 months has now become an attainable realistic goal. In the past, parents and paediatricians often did not suspect a hearing loss until the age of 2-3 years, after important speech and language milestones have not been met. By the time these milestones are missed, the hearing-impaired child has already experienced irreversible delays in speech and language development.

Answer: Congenital diaphragmatic herniaCongenital diaphragmatic hernia (CDH) occurs when the diaphragm muscle — the muscle that separates the chest from the abdomen — fails to close during prenatal development, and the contents from the abdomen (stomach, intestines and/or liver) migrate into the chest through this hole.Examination in infants with congenital diaphragmatic hernias include the following findings:Scaphoid abdomenBarrel-shaped chestRespiratory distress (retractions, cyanosis, grunting respirations)In left-sided posterolateral hernia: Poor air entry on the left, with a shift of cardiac sounds over the right chest| in patients with severe defects, signs of pneumothorax (poor air entry, poor perfusion) may also be foundAssociated anomalies: Dysmorphisms such as craniofacial abnormalities, extremity abnormalities, or spinal dysraphism may suggest syndromic congenital diaphragmatic herniaIleal atresia is a congenital abnormality where there is significant stenosis or complete absence of a portion of the ileum. There is an increased incidence in those with chromosomal abnormalities. Ileal atresia results from a vascular accident in utero that leads to decreased intestinal perfusion and subsequent ischemia a segment of bowel. This leads to narrowing, or in the most severe cases, complete obliteration of the intestinal lumen. In the postnatal period, an abdominal radiograph will show air in the dilated loops of proximal bowel. An ileal atresia is often discovered prenatally at a routine prenatal ultrasound scan or following the development of polyhydramnios. On ultrasound, there is frequently a proximal dilated intestinal segment.Meconium Ileus (MI) is a condition where the content of the baby’s bowel (meconium) is extremely sticky and causes the bowel to be blocked at birth. In most cases the bowel itself is complete and intact but it is just the inside that is blocked.In some cases there has been a twist of the bowel before birth, which has caused the bowel to be blind ending (an atresia). Most babies with meconium ileus (90%) have Cystic Fibrosis (CF) and it is this that has caused the sticky meconium. Meconium ileus is a rare condition affecting only 1 in 25,000 babies. There is normally a delay in your baby passing meconium (black sticky stool normally passed within 24 hours of delivery) and your baby may also be reluctant to feed and may vomit a green fluid called bile which would normally pass through the bowel.Your baby may be uncomfortable because of constipation and trapped air in the bowel and the abdomen (tummy) will become distended. Some babies present at delivery with a distended abdomen and may be unwell due to infection around the bowel.Pyloric stenosis is a problem that affects babies between birth and 6 months of age and causes forceful vomiting that can lead to dehydration. It is the second most common problem requiring surgery in new-borns. The lower portion of the stomach that connects to the small intestine is known as the pylorus. In pyloric stenosis, the muscles in this part of the stomach enlarge, narrowing the opening of the pylorus and eventually preventing food from moving from the stomach to the intestine.

CMV infection is usually asymptomatic in adults. However, if the mother is infected for the first time during pregnancy then there is high chances of this infection passing on to the foetus. CMV infection can cause blindness, deafness, learning difficulties, restricted growth etc. Hepatitis B, herpes simplex, syphilis and HIV do not present with these classical signs of CMV infection in new-borns. It is estimated that 10 stillbirths occur in England and Wales every year due to CMV infection. The foetus is most at risk in early pregnancy. There is no effective prevention.

Infection of chickenpox in the first half of pregnancy can result in congenital varicella syndrome. It presents as cerebral, cortical and cerebellar hypoplasia with convulsions and rudimentary digits. Prevention is by administering varicella vaccine, even before pregnancy. Varicella immunoglobulin is administered to pregnant women who are exposed to infection. Infection during pregnancy is treated with acyclovir.

Retinopathy screening need not be done on an annual basis for a 9-year-old child. Screening for diabetic retinopathy should begin at the age of 12.Diabetes mellitus is an increasing problem in both developing and developed countries alike. Some of the risk factors include:ObesityFamily historyFemale sex Asian and African racesPresence of acanthosis nigricans is seen with type 2 but not type 1 diabetesThe diagnosis is mostly incidental or subacute.The treatment aims are good blood sugar control, maintenance of normal BMI, and reduction of complications. The treatment modality also includes lifestyle modifications and cessation of smoking. Even after all this, diabetic ketoacidosis can still occur.Management of diabetes mellitus – NICE guidelines (Updated, 2015): – Standard release metformin should be offered from the moment of diagnosis.- HBA1c should be measured every three months. The target HBA1c level of 48 mmol/mol (6.5%) or lower is ideal for minimising the risk of long term complications.- Children should undergo an eye examination by an optician every two years.- Annual immunisation against influenza and pneumococcal infections are essential.- There is an increased risk of psychological and psychosocial difficulties if the child with type 1 diabetes is on insulin or oral hypoglycaemic medications. These include anxiety disorder, depression, behavioural and conduct disorders and family conflict.- Annual monitoring to be done for:Hypertension starting at diagnosis.Dyslipidaemia starting at diagnosis.Screening for microalbuminuria starting at diagnosis.Diabetic retinopathy from 12 years of age.

The x-ray is suggestive of bronchiectasis. The most probable aetiology especially considering recurrent chest infections at such a young age is cystic fibrosis.

Port-wine stains are a type of vascular birthmark caused by the abnormal development of capillaries in the skin. These pinkish-purplish discolorations present at birth and are associated with medical conditions such as Sturge-Weber syndrome, a neurocutaneous disorder involving the leptomeninges. Port wine stains are therefore associated with epilepsy, glaucoma or intellectual disability common in Sturge-Weber syndrome. Additional complications of Port wine stains include a loss of function if near the eye or mouth due to hypertrophy, or glaucoma if near the eyelid.

Adhesion formation might be reduced by minimally invasive surgical techniques and the use of adhesion barriers. Non-operative treatment is effective in most patients with ASBO. Contraindications for non-operative treatment include peritonitis, strangulation, and ischemia. When the adhesive aetiology of obstruction is unsure, or when contraindications for non-operative management might be present, CT is the diagnostic technique of choice. The principles of non-operative treatment are nil per os, naso-gastric, or long-tube decompression, and intravenous supplementation with fluids and electrolytes. When operative treatment is required, a laparoscopic approach may be beneficial for selected cases of simple ASBO.

The child most likely has nephritic syndrome which is characterised by a reduced renal function, proteinuria of non-nephrotic range, haematuria, erythrocyte casts, and oedema. Polyarteritis nodosa usually occurs in middle-aged men but can also be seen in young children. It is accompanied by severe systemic manifestations such as fever, malaise, weight loss and myalgia.Renal cell carcinoma usually presents around 55 years with the classic triad of haematuria, loin pain and a unilateral mass in the flank.Polycystic kidney disease usually presents in adult life with acute loin pain and palpation of masses in the flanks.

Puberty is a period of transitioning into adulthood by developing full reproductive potential by undergoing drastic physiological and psychological changes. For boys, it occurs around 9-16 years of age typically. The process of pubertal changes is usually divided into stages called tanner’s stages. The physiologic changes of puberty are initiated by the release of gonadotropin-releasing hormones from the hypothalamus, which then interact with numerous endogenous and environmental stimuli to bring about the physical pubertal features. Tanner stage 2 in boys is characterized by the thinning and reddening of the scrotal skin.The growth spurt of around 9cm per year is expected in boys, at the peak velocity.Testicular enlargement of >3cm commences puberty.Pubarche, in the absence of other secondary sexual characteristics, is pathological.Adrenarche is the increase in the secretion of adrenal androgens, occurring prior to increased gonadotropin release.

Based on the clinical scenario, the patient has features suggestive of acute otitis externa, which can be managed with topic antibiotics.Otitis externa:It can be classified as acute (< 3 weeks) or chronic (> 3 months). Frequent exposure to water, e.g. swimming, is a risk factor for the condition. Itching, pain, hearing loss and discharge are common complaints. Examination demonstrates oedema of the external auditory canal with discharge. Pain may be elicited on the movement of the tragus or pinna. First-line treatment is with topical drops/sprays for one week. Acidic preparations such as 2% acetic acid, antibiotic or combined antibiotic and corticosteroid preparations may be used (1% hydrocortisone and 0.3% gentamicin). Acetic acid can be used as the first-line treatment for mild cases without discharge or hearing impairment. On selecting an appropriate topical preparation remember that topical aminoglycosides are contraindicated if the tympanic membrane is perforated and that chloramphenicol ear drops cause contact dermatitis in approximately 10% of people. Clinoquinol, a combination of antibacterial and antifungal, may be preferred over aminoglycoside containing preparations due to the theoretical lower risk of ototoxicity and dermatitis. However, there is no clear evidence to support the use of one topical preparation over another.Other options:- Admit for IV antibiotics: First line management is with analgesia and topical antibiotic or combined antibiotic and corticosteroid preparations. Thus, IV antibiotics is not an appropriate action.- Oral antibiotics: Oral antibiotics like flucloxacillin or erythromycin are considered only for severe infections such as the spread of cellulitis beyond the ear canal. – Reassurance is not sufficient to treat these patients. They require topic antibiotic therapy.- Referral to ENT: Should be considered only in case of treatment failure. ENT referral can also be considered if there is cellulitis extending past the margin of the external ear canal, extreme pain or extensive swelling and discharge likely to require suction or the insertion of an ear wick. Urgent ENT referral is reserved for suspected cases of malignant otitis externa (with the extension of the condition into the adjacent bone and spreading osteomyelitis).

The sensitivity of a screening test can be described in a variety of ways, typically such as sensitivity being the ability of a screening test to detect a true positive, being based on the true positive rate, reflecting a test’s ability to correctly identify all people who have a condition, or, if 100%, identifying all people with a condition of interest by those people testing positive on the test.The specificity of a test is defined in a variety of ways, typically such as specificity is the ability of a screening test to detect a true negative, being based on the true negative rate, correctly identifying people who do not have a condition, or, if 100%, identifying all patients who do not have the condition of interest by those people testing negative on the test.Sensitivity=[a/(a+c)]×100Specificity=[d/(b+d)]×100a: True positiveb: False Positivec: False negatived: True negative

At the age of three years a child is to be able to dress and undress himself with supervision, eat with a spoon and fork, build a tower with 9 cubes, give their full name and copy a circle. The child will not be able to make good cuts with scissions until he is about 5 years old.

To quantify differences between percentages you can use Fisher’s exact test.Odds ratios, relative risks and number needed to treat are ways of quantifying differences between percentages in two groups, however are not in themselves significance tests.

A transverse lie is a common malpresentation. It occurs when the fetal longitudinal axis is perpendicular to the long axis of the uterus. The location of the spine determines if the foetus is back up (the curvature of the spine is in the upper part of the uterus) or back down (the curvature of the spine is in the lower part of the uterus).Good antenatal care, ECV, and elective caesarean section are the mainstay of the management.Spontaneous delivery of a term foetus is impossible with a persistent transverse lie and, in general, the onset of labour is an indication for the lower segment caesarean section (LSCS) in a case of a transverse lie.

Minimal change nephrotic syndrome leads to the loss of anti-thrombin III which protects the body from forming venous emboli. It may be triggered by virus, immunisations, medication, non-Hodgkin lymphoma, or leukaemiaCharacterised by oedema, proteinuria, hypoalbuminemia, and hypercholesterolemia.

Fabry disease (Angiokeratoma corporis diffusum) is an X-linked lysosomal disorder which occurs due to deficiency or absence of alpha-galactosidase A (α-GAL A) activity as a result of a genetic mutation in the GLA gene. As Fabry’s disease follows X-linked genetics it manifestis predominantly in men. Ongoing burning, tingling pain and discomfort, known as acroparesthesia, mainly affecting the hands and feet is the most debilitating symptom in childhood.

Duchenne muscular dystrophy has an X-linked recessive pattern of inheritance. Since the first son is affected by the disease, it means that the mother is a carrier. The male children will inherit the Y chromosome from their father and the X chromosome from their mother, having 50% chances of inheriting the X chromosome with the affected gene.

Infectious mastitis and breast abscesses are predominantly caused by bacteria that colonize the skin. S. aureus is the most common causative agent, followed by coagulase-negative Staphylococci. The majority of S. aureus isolated are now methicillin-resistant S. aureus (MRSA)Some breast infections (and up to 40% of breast abscesses) may be polymicrobial, with the isolation of aerobes (Staphylococcus, Streptococcus, Enterobacteriaceae, Corynebacterium, Escherichia coli, and Pseudomonas) as well as anaerobes (Peptostreptococcus, Propionibacterium, Bacteroides, Lactobacillus, Eubacterium, Clostridium, Fusobacterium, and Veillonella). A study of primary and recurrent breast abscesses showed that smokers were more likely to have anaerobes recovered (isolated in 15% of patients).Unusual breast infections may be the initial presentation of HIV infection. Typhoid is a well-recognized cause of breast abscesses in countries where this disease is prevalent.

The accuracy of the test for calcium levels in the blood is affected by the blood level of albumin. If albumin levels are low, the calcium level can also appear low.This is termed as pseudohypocalcemia.Hypocalcaemia usually presents with muscle spams. These can include spasms of voluntary muscle but also smooth muscle such as in the airways (causing bronchospasm) and in the heart (causing angina).

The IM dose of adrenaline for anaphylaxis in:< 6 months: 150 micrograms (0.15ml 1 in 1,000)6 months - 6 years: 150 micrograms (0.15ml 1 in 1,000)6 - 12 years: 300 micrograms (0.3ml 1 in 1,000)Adult and child > 12 years: 500 micrograms (0.5ml 1 in 1,000)Anaphylaxis:Anaphylaxis is an acute, rapidly progressing, potentially life-threatening IgE mediated Type I hypersensitivity reaction.It involves the release of mediators from mast cells, basophils and inflammatory cells. It is characterised by oedematous swelling of the airway mucosa giving rise to dyspnoea and respiratory distress. The most common cause of anaphylaxis in children is a food allergy.Risk factors for death in patients with anaphylaxis include asthma, age 11+, peanut allergy, and delay in adrenaline administration.Management of anaphylaxis includes:- ABCD- Remove the allergen- IM adrenaline or Nebulised adrenaline- IV Hydrocortisone – pro re nata IV fluid support. – Followed by observation.

The main cause of growth hormone (GH) deficiency is a pituitary tumour or the consequences of treatment of the tumour including surgery and/or radiation therapy.Sheehan’s syndrome (SS) is postpartum hypopituitarism caused by necrosis of the pituitary gland. It is usually the result of severe hypotension or shock caused by massive haemorrhage during or after delivery. Patients with SS have varying degrees of anterior pituitary hormone deficiency.Laron syndrome is Insulin-like growth factor I (IGF-I) deficiency due to GH resistance or insensitivity due to genetic disorders of the GH receptor causing GH receptor deficiency.

E. coli accounts for the majority of UTI’s in children. If this child responds well to treatment and has no recurrence of his symptoms, then no form of imaging is required, as per NICE advice for children aged 6 months to 3 years. Had the child been less than 6 months of age, then a USS at 6 weeks would be necessary.Other options:- Pseudomonas causes atypical UTI. This warrants ultrasonography within the acute illness phase as it may reflect an underlying pathology and DMSA at 4-6 months.- Recurrent UTI is defined as two or more episodes of pyelonephritis OR 1 pyelonephritis and one cystitis OR 3 or more cystitis. It requires USS at six weeks and DMSA at 4-6 months.- Septicaemia is a sign of an atypical UTI. This requires USS within the acute illness as it may reflect an underlying pathology and DMSA at 4-6 months.- Unwell 48hrs post antibiotics is a sign of an atypical UTI. This requires USS within the acute illness as may reflect underlying pathology and DMSA at 4-6 months.

Coarctation of the aorta may be defined as a constricted aortic segment that comprises localized medial thickening, with some infolding of the medial and superimposed neointimal tissue.The presence of associated defects and aortic arch anomalies, the extent of patency of the ductus arteriosus, the rapidity of the process of closure of the ductus arteriosus, and the level of pulmonary vascular resistance determine the timing of clinical presentation and the severity of symptoms. Young patients may present in the first few weeks of life with poor feeding, tachypnoea, and lethargy and progress to overt CHF and shock. These patients may have appeared well before hospital discharge, and deterioration coincides with closure of the patent ductus arteriosus. Presentation may be abrupt and acute with ductal closure.Neonates may be found to have tachypnoea, tachycardia, and increased work of breathing and may even be moribund with shock. Keys to the diagnosis include blood pressure (BP) discrepancies between the upper and lower extremities and reduced or absent lower extremity pulses to palpation. However, when the infant is in severe heart failure, all pulses are diminished.The murmur associated with coarctation of the aorta may be nonspecific yet is usually a systolic murmur in the left infraclavicular area and under the left scapula.

Alopecia areata is seen in 6-8.8% of patients with Down syndrome, but only 0.1% of patients with alopecia areata have Down syndrome. The high frequency of alopecia areata in patients with Down syndrome suggests that a genetic linkage for alopecia areata may exist on chromosome 21.

Homonymous hemianopia (HH) is a visual field defect involving either two right or the two left halves of the visual field of both eye. It results from the damage of the visual pathway in its suprachiasmatic part. The causes of HH include stroke, brain tumours, head injuries, neurosurgical procedures, multiple sclerosis and miscellaneous conditions. HH result in a severe visual impairment and affect a variety of cognitive visual functions. Patients with HH frequently have difficulties with reading and scanning scenes in sufficiently rapid fashion to make sense of things as a whole. They stumble, fall or knock objects in their surroundings, since they cannot see them and they are frequent surprised that somebody or something suddenly appeared in their visual field. The prognosis of visual field deficit recovery is highly variable and depends on the cause and severity of brain nd optic pathway injury.

The hypoglossal nerve (CN XII) provides motor innervation to all of the intrinsic and extrinsic muscles of the tongue except for the palatoglossus muscle, which is innervated by the vagus nerve (CN X). It runs superficial to the hyoglossus muscle. Lesions of the hypoglossal nerve cause deviation of the tongue to the ipsilateral (i.e., damaged) side.Taste to the anterior two-thirds of the tongue is achieved through innervation from the chorda tympani nerve, a branch of the facial nerve (CN VII). General sensation to the anterior two-thirds of the tongue is by innervation from the lingual nerve, a branch of the mandibular branch of the trigeminal nerve (CN V3). The lingual nerve is located deep and medial to the hyoglossus muscle and is associated with the submandibular ganglion.On the other hand, taste to the posterior one-third of the tongue is accomplished through innervation from the glossopharyngeal nerve (CN IX), which also provides general sensation to the posterior one-third of the tongue.Taste perception also is performed by both the epiglottis and the epiglottic region of the tongue, which receives taste and general sensation from innervation by the internal laryngeal branch of the vagus nerve (CN X). Damage to the vagus nerve (CN X) causes contralateral deviation (i.e., away from the injured side) of the uvula.

The clinical scenario provided is highly suggestive of third-degree burns (or full-thickness burns) that may have invaded the deeper levels up to dermis, evident from the insensate nature of the lesion.Degrees of Burns:- First degree burns are superficial second-degree burns.- Second-degree burns are just deeper than that of first-degree burns but vary enormously in other properties.- Third-degree burns are full-thickness burns which are leathery in consistency, and insensate. These burns do not heal on their own. The sensory neurons present in the skin at the deeper levels are destroyed completely and hence provide a paradoxical lack of pain.- Fourth-degree burns involving the subcutaneous tissues, tendons, and bones are very difficult to manage.Assessment of the extent of the burns for the treatment employs specialized charts, such as Lund and Browder charts and Wallace rule of nines.The Lund and Browder chart is, however, considered the most accurate.Wallace’s Rule of Nines can be used for children >16 years: – Head + neck = 9%- Each arm = 9%- Each anterior part of leg = 9%- Each posterior part of leg = 9%- Anterior chest = 9%- Posterior chest = 9%- Anterior abdomen = 9%- Posterior abdomen = 9%

The presentation of the child is highly suggestive of Henoch-Schonlein purpura (HSP). It is an IgA-mediated, autoimmune hypersensitivity vasculitis that targets the small vessels of the skin, GI tract, kidneys, and joints.It is most commonly seen in children aged 3 – 6 years old and is twice as common in boys than girls. Preceding viral URTI with low-grade pyrexia is common. The most common organism associated with HSP is, however, Group A streptococcal infection.A purpuric rash is seen on the back of the legs and buttocks and can less frequently affect the arms. Arthralgia is common (usually knees/ankles) in these patients.Abdominal pain and bloody diarrhoea may occur. And half of the children with HSP have renal involvement. Rarely, it can lead to end-stage renal failure.Treatment includes adequate hydration, occasionally steroids, and other immunosuppressants. The disease can recur in 1 in 3 children.

The adult height potential may be calculated for a male child by (father’s height in cm + mother’s height in cm) / 2 then add 7 cm.In the scenario provided: (170 + 150)/2 + 7 = 167 cm = 1.67 m.For a female child by (father’s height in cm + mother’s height in cm) / 2 then minus 7 cm.This can then be plotted on a height centile chart to find the mid-parental centile.Causes of short stature include:- Normal variant (often familial)- Constitutional delay of growth and puberty- Chronic illness, e.g. cystic fibrosis, inflammatory bowel disease- Endocrine: growth hormone deficiency, hypothyroidism, steroid excess syndromes: Turner’s, Down’s, Prader-Willi- Skeletal dysplasias, e.g. achondroplasia

Tension headache presents with pain that is pressing or tightening in quality, mild or moderate, and located bilaterally. It usually does not get worse with activities and may last from minutes to weeks.

Box plots can be used to display numerical outcomes and give valid summaries (median and interquartile range or IQR) for any distributional form that the outcomes might take. Additionally, they show outlying values and provide data summaries that are not unduly influenced by those outliersOther options:- The box itself represents the interquartile range, with the two whiskers representing the variability outside the upper and lower quartiles.- Variability is represented with whiskers and feathers are used in fan charts.They are not as informative as showing the actual values but can be used to make comparisons of medians and IQRs between subgroups.

Puberty is when a child’s body begins to develop and change as they become an adult.The average age for girls to begin puberty is 11, while for boys the average age is 12.It’s completely normal for puberty to begin at any point from the ages of 8 to 14. The process can take up to 4 years.

Foreign body aspiration (FBA) commonly occurs in children aged 1–3 years. FBA typically presents with sudden onset of coughing and choking, followed by stridor and dyspnoea. Obstruction of the larynx or trachea is a potentially life-threatening situation that causes severe respiratory distress, cyanosis, and suffocation. Most commonly, the foreign body (FB) becomes lodged in the main and intermediate bronchi| approx. 60% of FB are located in the right main bronchus due to the more vertical orientation compared to the left main bronchus. Reduced breath sounds on the one side only would not be explained by a tracheal obstruction as it would cause reduced breath sounds bilaterally and a more severe clinical picture.

The external aspect of the tympanic membrane is lined by stratified squamous epithelium. Clinical correlation: Following middle ear infections, this type of epithelium can migrate into the middle ear through a perforated tympanic membrane.The ear is composed of three anatomically distinct regions: – External ear: Auricle is composed of elastic cartilage covered by skin. The lobule has no cartilage and contains fat and fibrous tissue. External auditory meatus is variable in length, measuring approximately 2.5cm long in fully grown children. Lateral third of the external auditory meatus is cartilaginous, and the medial two-thirds is bony. The greater auricular nerve innervates the region. The auriculotemporal branch of the trigeminal nerve supplies most of the external auditory meatus and the lateral surface of the auricle. – Middle ear: It is the space between the tympanic membrane and cochlea. The aditus leads to the mastoid air cells is the route through which middle ear infections may cause mastoiditis. Anteriorly the eustachian tube connects the middle ear to the nasopharynx. The tympanic membrane consists of an outer layer of stratified squamous epithelium, a middle layer of fibrous tissue and an inner layer of mucous membrane continuous with the middle ear. The chorda tympani nerve passes on the medial side of the pars flaccida. The glossopharyngeal nerve and pain innervate the middle ear. Thus, pain may radiate to the middle ear following tonsillectomy. – Ossicles:Malleus attaches to the tympanic membrane (the Umbo). Malleus articulates with the incus (synovial joint). Incus attaches to stapes (another synovial joint). – Internal ear:It consists of the cochlea, semicircular canals, and vestibule. Organ of Corti is the sense organ of hearing and is located on the inside of the cochlear duct on the basilar membrane. Vestibule accommodates the utricle and the saccule. These structures contain endolymph and are surrounded by perilymph within the vestibule. The semicircular canals lie at various angles to the petrous temporal bone. All share a common opening into the vestibule.

Eczema herpeticum (also called Kaposi varicelliform eruption) is a disseminated viral illness usually associated with lymphadenopathy.It is most often caused by Herpes Simplex type 1 or type 2. Occasionally, other viruses such as coxsackievirus A16 may cause eczema herpeticum. Affected children usually develop itchy blisters and fever after coming in contact with an affected individual who may or may not display cold sores.It is characterised by an itchy and sometimes painful cluster of blisters most commonly on the face initially. This spreads over one to several weeks resulting in further crops of blisters which can become confluent. Lymphadenopathy and fever are common in these patients.The severity varies from mild illness to life-threatening, especially in immunocompromised children or young infants. It is markedly more common in children with atopic dermatitis. It is one of the few dermatological emergencies, and oral antivirals are often indicated. Referral to an ophthalmologist may be needed if there is eyelid or eye involvement. Occasionally, superadded skin infections caused by staphylococci and streptococci can occur.

Nonspecific triggers of inflammation in patients with atopic dermatitis may include physical or chemical irritants. The following simple measures should be followed in daily life to reduce the frequency and severity of irritant-induced atopic dermatitis flares :Skin care products that contain alcohol and astringents should be avoided.New clothes should be laundered before use to remove formaldehyde and other chemicals.Liquid detergents are preferred over powder detergents for laundering clothes, as liquids are easier to rinse out. A second rinse cycle may also improve removal of residual detergent.Patients should shower immediately after swimming in chlorinated pools and should subsequently apply moisturizer.Fragrance-free skin products that are hypoallergenic or made for sensitive skin may be less irritating than other kinds of skin products.Prenatal and postnatal probiotic supplementation may be helpful in preventing the development of atopic dermatitis in young children. In a 2008 meta-analysis, the most commonly studied probiotic was Lactobacillus rhamnoses GG. Larger, randomized controlled studies are needed to confirm these initial findings.Breastfeeding during the first 4 months of life may reduce the incidence and severity of childhood atopic disease but only modestly and only in those at high risk.

Supination is the rotation of the forearm so that the palm of the hand faces anteriorly. This is performed by the biceps brachii and supinator of the extensor muscles of the thumb. The opposite action of moving the palm from an anterior-facing position to a posterior-facing position is called pronation. Pronation is performed by the pronator teres and pronator quadratus.

The most appropriate step in this patient would be to admit the patient for enteral rehydration via a nasogastric tube.Enteral rehydration:Oral rehydration is the most preferred way of rehydrating children. If a child is not tolerating small-frequent-feeds, then nasogastric rehydration is an underused next best step. The fluid can be run through a continuous pump so that it is better tolerated. Note:Intravenous fluids are effective but can have profound effects on the serum electrolyte balance if not monitored closely. Most children will tolerate fluids in an emergency department, but failure to take fluids orally is not an indication for intravenous therapy.

Tuberous sclerosis, an autosomal dominant disorder, may present with a variety of symptoms, including seizures, developmental delay, behavioural problems, skin abnormalities, and lung and kidney disease. Hamartomas are often associated.

A vasovagal episode or vasovagal syncope is the most common form of reflex syncope. Reflex syncope is a general term used to describe types of syncope resulting from a failure in autoregulation of blood pressure, and ultimately, in cerebral perfusion pressure resulting in transient loss of consciousness. The mechanisms responsible for this are complex and involve both depression of cardiac output as well as a decrease in vascular tone. Other types of reflex syncope include carotid sinus syncope and situational syncope, for instance, cough or micturition syncope. Vasovagal syncope may be triggered by pain or emotional upset, although frequently a specific trigger cannot be identified.

Clotrimazole interferes with the ergosterol biosynthesis by decreasing ergosteron I biosynthesis, increasing membrane permeability, and disrupting membrane-bound enzyme systems.Vaginal candidiasis is an extremely common condition. Predisposing factors include:- diabetes mellitus- drugs: antibiotics, steroids- pregnancy- immunosuppression – iatrogenic

3-year-old milestonesSocial and EmotionalCopies adults and friends Shows affection for friends without prompting Takes turns in games Shows concern for crying friend Understands the idea of “mine” and “his” or “hers” Shows a wide range of emotions Separates easily from mom and dad May get upset with major changes in routineDresses and undresses self Language/CommunicationFollows instructions with 2 or 3 steps Can name most familiar things Understands words like “in,” “on,” and “under” Says first name, age, and sexNames a friend Says words like “I,” “me,” “we,” and “you” and some plurals (cars, dogs, cats) Talks well enough for strangers to understand most of the time Carries on a conversation using 2 to 3 sentences Cognitive (learning, thinking, problem-solving)Can work toys with buttons, levers, and moving parts Plays make-believe with dolls, animals, and people Does puzzles with 3 or 4 pieces Understands what “two” means Copies a circle with a pencil or crayon Turns book pages one at a time Builds towers of more than 6 blocks Screws and unscrews jar lids or turns the door handle Movement/Physical DevelopmentClimbs well Runs easily Pedals a tricycle (3-wheel bike) Walks up and downstairs one foot on each step

Synchronized IMV (SIMV) with pressure support, used in the alert infant. SIMV guarantees a minimum minute volume while allowing the patient to trigger spontaneousbreaths at a rate and volume determined by the patient. Extra breaths are boosted with pressure support. Tidal Volume (Vt) is normally approximately 6-10 mL/kg and 4-6 ml/kg in the preterm.Respiratory rate (RR) is usually 30-60 BPM. Tidal volume and respiratory rate are relatedto respiratory minute volume as follows: Vm(mL/min) = Vt x RR .This baby is overventilated with a low CO2. Tidal volumes should generally be targeted at 4–6 ml/kg and this baby is being targeted at 9 ml/kg which exposes the baby to damage to the distal airways from this ventilation which can lead to bronchopulmonary dysplasia.

Damage to the left parietal lobe can result in what is called Gerstmann’s Syndrome. It includes right-left confusion, difficulty with writing (agraphia) and difficulty with mathematics (acalculia). It can also produce disorders of language (aphasia) and the inability to perceive objects normally (agnosia).Damage to the right parietal lobe can result in neglecting part of the body or space (contralateral neglect), which can impair many self-care skills such as dressing and washing. Right side damage can also cause difficulty in making things (constructional apraxia), denial of deficits (anosognosia) and drawing ability.Bi-lateral damage (large lesions to both sides) can cause Balint’s Syndrome, a visual attention and motor syndrome. This is characterized by the inability to voluntarily control the gaze (ocular apraxia), inability to integrate components of a visual scene (simultanagnosia), and the inability to accurately reach for an object with visual guidance (optic ataxia)Special deficits (primarily to memory and personality) can occur if there is damage to the area between the parietal and temporal lobes.Left parietal-temporal lesions can affect verbal memory and the ability to recall strings of digits. The right parietal-temporal lobe is concerned with non-verbal memory.Right parietal-temporal lesions can produce significant changes in personality.

Omega-shaped epiglottis is a characteristic feature in the X-ray of a patient with laryngomalacia.

Various types of birthmarks are commonly seen in children of different age groups. Birthmarks can be broadly classified as pigmented and vascular birthmarks. Port-wine stain (nevus flammeus) is an example of a vascular birthmark, and is characterized by a reddish-purple discoloration of the skin due to abnormal underlying skin vasculature. Port-wine stain has also been associated with vascular diseases like Sturge-weber syndrome, which is a congenital neurocutaneous disorder. In Sturge-weber syndrome, the port-wine stain affects the skin around the ophthalmic branch of trigeminal nerve.

Buckwheat is not wheat. It’s a seed rather than a grain, which means it’s gluten-free and safe for people with celiac disease and non-celiac gluten sensitivity. It is an excellent source of fibre and nutrients.

An important predictor of the foetal well-being is the evaluation of amniotic fluid volumes, commonly done using ultrasonography. Amniotic fluid index (AFI) is calculated by measuring the largest vertical diameter of the fluid pocket in all four quadrants of the uterine cavity and then added together. Oligohydramnios or decreased amniotic fluid volume can be defined as an AFI less than 5cm and occurs in about 4-5% of the pregnancies. It is associated with a number of foetal abnormalities and complications. Foetal abnormalities that lead to oligohydramnios include: premature rupture of membranes, intrauterine growth retardation, and congenital foetal abnormalities among others. A single umbilical artery is an anatomical defect of the umbilical cord, which leads to IUGR, uteroplacental insufficiency and may be associated with multiple congenital abnormalities as well, which all ultimately lead to the development of oligohydramnios. Foetal hydrops, developmental dysplasia of the hip and, macrosomia lead to polyhydramnios. Cleft palate is not associated with any of them.

Cystic fibrosis is a genetic disease that interferes with the normal development of the child. It manifests with recurrent episodes of pneumonia accompanied by coughing, wheezing and dyspnoea. The appetite is normal but weight gain seems difficult. This condition also affects bowel habits with repeated gastrointestinal infections. The gold standard for the diagnosis is considered the sweat test which reveals abnormally high levels of Cl-.

The most appropriate action in this baby would be to perform HIV PCR and commence cART and PCP prophylaxis if HIV positive.Treatment guidelines for HIV-positive infants state that all should receive combination antiretroviral therapy (cART) and Pneumocystis jiroveci pneumonia (PJP) prophylaxis, irrespective of CD4 count or viral load.

Infective endocarditis occurs when microorganisms enter the bloodstream and infect damaged endocardium or endothelial tissue. It most commonly involves the heart valves (either native or prosthetic), but it may also occur at the site of a septal defect, on the chordae tendineae, or on the mural endocardium. The prototypic lesion is at the site of the infection| the vegetation is a mass of platelets, fibrin, microcolonies of microorganisms, and scant inflammatory cells. Endocarditis is classified as acute or subacute, which applies to the features and the progression of infection until diagnosis.The oral cavity, the skin, and the upper respiratory tract are the primary portals for Streptococcus viridans| Staphylococcus species| and Haemophilus aphrophilus, Aggregatibacter (formerly Actinobacillus) actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, and Kingella kingae (HACEK) organisms. Streptococcal and staphylococcal organisms are responsible for more than 80% of cases of bacterial IE.Streptococcus viridans accounts for approximately 50-60% of cases of subacute disease.While S aureus infection is the most common cause of IE, including Prosthetic valve endocarditis, acute IE, and IV Drug Abusers IE

Infective endocarditis (IE) is an acute infective pathology of the endocardium secondary to some underlying cardiac pathology like VSD and TOF. Most commonly, it is bacterial in origin, caused by staphylococcus aureus in the majority of cases. Clinical features include fever, arthralgias, weight loss, anorexia, new-onset, or changing existing murmur. Skin manifestations include Osler’s nodes, Janeway lesions, splinter haemorrhages, and clubbing. Roth spots are conjunctival haemorrhages found in IE. Beau’s lines are not found in IE.

The most probable diagnosis for the patient would be DiGeorge syndrome due to 22q11 deletion. It causes embryonic defects of the third and fourth branchial arches. It is sporadic in 90% of cases and 10 % inherited from parents as autosomal dominant.Characterised by distinct facial features (micrognathia, cleft palate, short philtrum, and low-set ears), hypocalcaemia, mental retardation, cardiac defects (especially tetralogy of Fallot), and immune deficiencies.A useful memory aid is CATCH-22:- Cardiac defects- Abnormal facial features- Thymic aplasia/hypoplasia- Cleft palate- Hypocalcaemia/Hypoparathyroidism- 22 – Due to 22q11 deletion
