Vitamin E deficiency in premature infants has been described as being associated with low haemoglobin levels in the 2nd month of life, haemolytic anaemia associated with thrombocytosis. Recently, low vitamin E concentrations were suspected as being associated with sudden death in infancy.

Alport syndrome is a genetic condition characterized by kidney disease, hearing loss, and eye abnormalities. Alport syndrome can have different inheritance patterns. About 80 percent of cases are caused by mutations in type IV collagen genes (COL4A5) and are inherited in an X-linked autosomal recessive pattern, although other inheritance patterns exist. Alport syndrome has autosomal dominant inheritance in about 5 percent of cases.

People with Alport syndrome experience progressive loss of kidney function. Almost all affected individuals have blood in their urine (haematuria), which indicates abnormal functioning of the kidneys. Many people with Alport syndrome also develop high levels of protein in their urine (proteinuria). The kidneys become less able to function as this condition progresses, resulting in end-stage renal disease (ESRD).

People with Alport syndrome frequently develop sensorineural hearing loss, which is caused by abnormalities of the inner ear, during late childhood or early adolescence. Affected individuals may also have misshapen lenses in the eyes (anterior lenticonus) and abnormal coloration of the light-sensitive tissue at the back of the eye (retina). These eye abnormalities seldom lead to vision loss.

Significant hearing loss, eye abnormalities, and progressive kidney disease are more common in males with Alport syndrome than in affected females.

Reed-Sternberg cells are classically associated with Hodgkin lymphoma.Classical diagnostic Reed-Sternberg cells are large (15 to 45 micrometres), have abundant slightly basophilic or amphophilic cytoplasm and have at least two nuclear lobes or nuclei. Diagnostic Reed-Sternberg cells must have at least two nucleoli in two separate nuclear lobes. The nuclei are large and often rounded in contour with a prominent, often irregular nuclear membrane, pale chromatin and usually one prominent eosinophilic nucleolus, with perinuclear clearing (halo), resembling a viral inclusion.

47,XYY syndrome is characterized by an extra copy of the Y chromosome in each of a male’s cells. Although many males with this condition are taller than average, the chromosomal change sometimes causes no unusual physical features. Most males with 47,XYY syndrome have normal production of the male sex hormone testosterone and normal sexual development, and they are usually able to father children.47,XYY syndrome is associated with an increased risk of learning disabilities and delayed development of speech and language skills. Affected boys can have delayed development of motor skills or hypotonia.Other signs and symptoms of this condition include hand tremors or other involuntary movements (motor tics), seizures, and asthma. Males with 47,XYY syndrome have an increased risk of behavioural, social, and emotional difficulties compared with their unaffected peers. These problems include attention-deficit/hyperactivity disorder (ADHD)| depression| anxiety| and autism spectrum disorder.Physical features related to 47,XYY syndrome can include increased belly fat, macrocephaly, macrodontia, flat feet (pes planus), fifth fingers that curve inward (clinodactyly), widely spaced eyes (ocular hypertelorism), and scoliosis. These characteristics vary widely among affected boys and men.

Congenital adrenal hyperplasia is a common cause of virilisation in females that can present as ambiguous genitalia at birth. Deficiency of the 21-alphahydroxylase enzyme is implicated in excess mineralocorticoid and androgens produced by the adrenal gland. Virilisation occurs when excess androgens are converted to testosterone in a genetically female foetus, causing the genitalia to resemble male genitalia. A deficiency of 5-alpha hydroxylase would rather decrease the production of testosterone and lead to the presentation of external female genitalia in a genetically male foetus. Autoantibodies against glutamic acid are seen in type 1 diabetes mellitus, while defects in the AIRE gene and the FOXP3 affect components of the immune system.

Haemophilia is a X-linked recessive disorder. In X-linked recessive inheritance only males are affected. An exception to this seen in examinations are patients with Turner’s syndrome, who are affected due to only having one X chromosome. X-linked recessive disorders are transmitted by heterozygote females (carriers) and male-to-male transmission is not seen. Affected males can only have unaffected sons and carrier daughters.

Based on the presenting features, the patient has developed a septal haematoma after the trauma. Septal hematoma:In this condition, blood collects between the septal cartilage and the perichondrium. The patient classically presents with symptoms of nasal difficulty and pain following a nasal injury. Care should be taken not to misdiagnose a septal haematoma as a blood clot on the septum. In the case of a septal haematoma the swelling will typically be visible on both sides of the septum although this is not always the case. Referral to an ENT surgeon is indicated because, if untreated, there is a high risk of cartilage breakdown and complications related to infection.Other options:- The nosebleed has now stopped therefore compression is no longer required. The boy has developed a septal haematoma after traumatic injury. – CT head is not indicated in this patient as the diagnosis is clearly a septal hematoma.- Management of a septal hematoma consists of drainage and antibiotics. There is no role for intranasal corticosteroids.- If untreated, there is a high risk of cartilage breakdown and complications related to infection. Thus, referral to the ENT is essential| reassurance and discharge can lead to complications.

The baby may have hydrocephalus and no surgery can be done until it is excluded.Cranial sonography is an important part of neonatal care in general, and high-risk and unstable premature infants, in particular. It allows rapid evaluation of infants in the intensive care units without the need for sedation and with virtually no risk. Expectedly, sonography represents an ideal imaging modality in neonates due to its portability, lower cost, speed, and lack of ionizing radiations. Although there are numerous indications for cranial sonography, it appears to be most useful for detection and follow-up of intracranial haemorrhage, hydrocephalus, and periventricular leukomalacia (PVL).

Among the given options, the most likely cause for the patient’s presenting symptoms is acute interstitial nephritis secondary to anti-tubercular therapy (ATT)Drug-induced acute interstitial nephritis can occur following treatment with beta-lactams, sulphonamides, rifampicin, ethambutol, and erythromycin. They can cause an acute allergic reaction with the infiltration of immune cells.Acute interstitial nephritis is said to be the most common renal complication in patients undergoing anti-TB treatment. Rifampicin is the most implicated drug, although ethambutol can also be a cause. The pathogenesis involves an immune-complex mediated acute allergic response, which leads to their deposition on renal vessels, the glomerular endothelium, and the interstitial area. Other options:Isoniazid does not affect the kidneys. Pulmonary-renal syndrome is a feature of Goodpasture’s syndrome. It is characterized by renal failure and lung haemorrhage. Severe cardiac or renal failure ensues and is complicated by pulmonary oedema, systemic lupus erythematosus, Henoch-Schönlein purpura, and cryoglobulinemia.

Among the options provided, the most characteristic finding that can be expected in his patient’s urine microscopy is RBC casts. Red cell casts are a characteristic feature of acute nephrotic syndrome. Other options:- Hyaline casts may be seen in normal urine, particularly after exercise. – Coarse granular casts occur in glomerular and tubular disease. – Tubular cell casts may be seen in patients with acute tubular necrosis. – The presence of 10 or more white blood cells/mm3 is abnormal and indicates an inflammatory reaction, most commonly due to infection.

Perthes’ disease is a disease of the hip in children. It presents with pain that is typically located in the groin area. The pain is often present only during physical activity. Most children seek medical attention because of limping.

Osgood–Schlatter disease is pain caused by inflammation of the patella tendon at the tibial insertion.

Slipped upper femoral epiphysis occurs classically in adolescence (M:F = 3:2)

Because the initial chest X-ray returned an anomaly, a skeletal survey is the best option. Also known as a bone survey, the skeletal survey is a series of X-rays that will help analyse the structure of all the bones in the body. Because the child is not very active yet presents with bruising, the child protection register should also be checked but only after a skeletal survey has been conducted.

The patient shows features of neurofibromatosis. The most likely cause for hypertension in this patient would be renal artery stenosis.Note:Neurofibromatosis is an inherited autosomal dominant disorder which could have affected this girl’s father, and she appears to have the classic skin lesions. A renal bruit might be heard in these patients. Polycystic kidney disease can occur in association with tuberous sclerosis, which also has skin lesions associated (different from those described in this patient). Most causes of hypertension in childhood have underlying renal causes, and a renal ultrasound with doppler is the first-line investigation of choice. Even if this is normal, further imaging would be indicated here, for example, isotope renal scans and angiography.

The average amount of energy required by a well preterm baby in a thermo-neutral environment is 50/kcal/kg to maintain essential body functions while it takes about 70 kcal/kg/day for optimal growth. It is important to ensure that enough proteins are given per calorie to limit catabolism and promote cell building. Caloric need usually increases when the baby is ill.

3,4-methylenedioxy-methamphetamine (MDMA) is a synthetic drug that alters mood and perception (awareness of surrounding objects and conditions). It is chemically similar to both stimulants and hallucinogens, producing feelings of increased energy, pleasure, emotional warmth, and distorted sensory and time perception. MDMA’s effects last about 3 to 6 hours, although many users take a second dose as the effects of the first dose begin to fade. Over the course of the week following moderate use of the drug, a person may experience:irritabilityimpulsiveness and aggressiondepressionsleep problemsanxietymemory and attention problemsdecreased appetitedecreased interest in and pleasure from sex

Congenital cytomegalovirus infection causes: jaundice, hepatosplenomegaly, petechia, microcephaly, hearing loss and seizures.

To prevent mother to child transmission in the case of an HIV infected mother, guidelines have been put in place in the that guide practices. During pregnancy the risk of intrauterine transmission is quite low, as is the risk of transmission during vaginal delivery. As a result the number of women that choose to have caesarean sections have fallen, with vaginal births increasing by 40%. One factor that can however increase the risk of mother to child HIV transmission is concurrent Hepatitis C infection which double the risk of vertical transmission.

Individuals with Down syndrome are at increased risk for a variety of eye and vision disorders. Fortunately, many of these eye problems can be treated, especially if discovered at an early age. The quality of life can be further enhanced by the proper assessment and correction of eye problems. The most common eye findings include:- Refractive errors – Children with Down syndrome are more likely to need glasses than are other children. This may be due to myopia (near-sightedness), hyperopia (far-sightedness), and/or astigmatism. Refractive error may develop early in life or later on.- Strabismus – Between 20% and 60% of individuals with Down syndrome have eyes that are misaligned (strabismus). Esotropia (eyes that drift in) is most common while exotropia(eyes that drift out) occurs less frequently. Strabismus may be treated with glasses, patching and/or eye muscle surgery.- Keratoconus – A cone shaped distortion of the cornea (front layer of the eye), occurs in up to 30% of those with Down syndrome. Keratoconus is usually diagnosed around puberty and should be monitored regularly. Blurred vision, corneal thinning, or corneal haze may result from keratoconus. Keratoconus is worsened by eye rubbing| therefore, eye rubbing should be discouraged.- Cataracts – There is an increased incidence of congenital cataracts (present at birth) as well as acquired cataracts (develop later). Cataracts may progress slowly and should be monitored regularly, with surgical treatment performed when appropriate.- Glaucoma- There is an increased risk of infantile glaucoma (elevated pressure within the eye).- Blepharitis – Inflammation of the eyelids with redness at the edge of the lids and crusting around the lashes may occur and cause a feeling of dryness or burning. Treatment is with eyelid hygiene and topical antibiotics.- Tearing – Excessive tears or watering of the eyes may occur because the drainage channels are blocked or narrow (nasolacrimal duct obstruction). This may require surgical intervention.- Nystagmus – This is an involuntary “back-and-forth” movement or shaking of the eyes. It can affect vision to a mild or severe degree.

When a child does not hear the sound in the middle during Weber test, it means they either they have a conductive hearing loss on the side they hear the sound, or a sensorineural hearing loss on the opposite side. Rinne’s test helps distinguish between the two. In this particular case, the hearing loss is most probably conductive due to the middle ear effusion. Therefore, Weber’s test should be localised to the left and Rinne’s should be positive on the right.

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 endocardial cushions in the heart are the mesenchymal tissue that make up the part of the atrioventricular valves, atrial septum and ventricular septum. An incomplete fusion of these mesenchymal cells can cause an atrioventricular septal defect. The terms endocardial cushion defect, atrioventricular septal defect and common atrioventricular canal defect can be used interchangeably with one another.

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

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.

Pyloric stenosis affects infants, typically in the second to fourth weeks of life and is caused most commonly by hypertrophy and thickening of the pylorus. It usually presents with projectile vomiting and failure to thrive. The infant usually has a normal appetite. Features include: ‘projectile’ vomiting, typically 30 minutes after a feed, constipation and dehydration may also be present and a palpable mass may be present in the upper abdomen.

This is the clinical picture of dermatitis herpetiformis associated with gluten-sensitive enteropathy. To establish the diagnosis, you should measure the coeliac antibodies. Darrier’s sign (where the skin urticates when it is stroked) is positive in urticaria pigmentosa.

Fertilization occurs when the sperm reaches an egg released during ovulation. At the time of fertilization, the interaction of sperm with the zona pellucida stimulates the release of calcium. This process initiates a corona reaction that prevents polyspermy.

In an acute and severe asthma attack the child cannot complete sentences in one breath because they are too breathless. The O2 saturation is less than 92% and PEF is between 33-50% best or predicted. In children that are 2-5 years old, HR is more than 140 bpm and more than 125 bpm in those older than 5 years old. The RR in children between 2-5 years old is more than 40/min, and more than 30/min in those older than 5 years old.

The best answer is Polycystic Ovarian Syndrome (PCOS), supported by amenorrhea, obesity and acne. High insulin levels are indicative of PCOS and exclude Cushing syndrome (as this is associated with low insulin levels).

Patients with breast cancer develop clinical symptoms rather late at advanced tumour stages. Typical signs may include:Changes in breast size and/or shape| asymmetric breastsPalpable mass: typically a single, nontender, firm mass with poorly defined margins, most commonly in the upper outer quadrantSkin changes: Retractions or dimpling (due to tightening of the Cooper ligaments), Peau d’orange: skin resembling an orange peel (due to obstruction of the lymphatic channels): Redness, oedema, and pitting of the hair folliclesNipple changes: inversion, blood-tinged dischargeAxillary lymphadenopathy: firm, enlarged lymph nodes (> 1 cm in size), that are fixed to the skin or surrounding tissueIn advanced stages: ulcerations

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.
