The trisomy 18 syndrome, also known as Edwards syndrome, is a common chromosomal disorder due to the presence of an extra chromosome 18, either full, mosaic trisomy, or partial trisomy 18q. The condition is the second most common autosomal trisomy syndrome after trisomy 21.Currently, most cases of trisomy 18 are prenatally diagnosed, based on screening by maternal age, maternal serum marker screening, or detection of sonographic abnormalities (e.g., increased nuchal translucency thickness, growth retardation, choroid plexus cyst, overlapping of fingers, and congenital heart defects ).The main clinical features include prenatal growth deficiency, characteristic craniofacial features (dolichocephaly, short palpebral fissures, micrognathia external anomalies of the ears, and redundant skin at the back of the neck), distinctive hand posture (overriding fingers: index finger overlapping the third and 5th finger overlapping the 4th), nail hypoplasia, short hallux, underdeveloped thumbs, short sternum, and club feet and major malformations (particularly involving the heart).

The symptoms of a partial generalized seizure are consistent with this patient.

The boy had a renal transplant, for which he needs immune suppression. For the exogenous immune suppression an exogenous steroid is needed, which in this case is responsible for the primary Cushing syndrome manifesting with short stature. The administration of steroids before the physiological fusion of the growth plate can lead to premature fusion with permanent cessation of bone growth.

Congenital TB symptoms typically develop during the second or third week of life and include poor feeding, poor weight gain, cough, lethargy, and irritability. Other symptoms include fever, ear discharge, and skin lesions.Signs of congenital TB include failure to thrive, icterus, hepatosplenomegaly, tachypnoea, and lymphadenopathy.

Congenital hypothyroidism results from insufficient levels of thyroid hormone in the body since birth, which is either due to dysgenesis of the thyroid gland or dyshormonogenesis. The important features of this disease include coarse facial features (macroglossia, large fontanelles, depressed nasal bridge, hypertelorism, etc.), failure to thrive, cardiomegaly, hypotonia, umbilical hernia, and low core body temperature among many others. Frontal bossing is the usual feature of rickets and acromegaly. Mitral regurgitation is not usually associated with congenital hypothyroidism.

The child has a history of pharyngitis followed 10 days later by signs of glomerulonephritis. In this particular case, it is most probably a post-streptococcus glomerulonephritis which accounts for 80% of paediatric cases of glomerulonephritis.

Polycythaemia is a condition in which there is an increased red cell mass and increasing blood viscosity, which decreases its ability to flow. It is not associated with food allergies, but is fundamentally caused by either an overproduction of red blood cells, or a reduction in the volume of plasma. Abdominal pain, constipation, loose and frequent stools, and pallor are all non IGE mediated symptoms of food allergy according to NICE guidelines in the UK.

NICE guidelines suggest that when a child’s single risk factor is 2 vomits, the child should be observed for 4 hours from the time of the injury, instead of having a CT.

Bowel sounds in the chest and curved NG tube are suggestive of a diaphragm rupture, which has caused herniation of bowel into the thoracic cavity through the defect in the diaphragm.

The Glasgow Coma Scale, being inappropriate for use in children (especially below the age of 5) as they are unable to elicit the verbal response as per the adult GCS. Therefore, GCS for the paediatric age group was modified to Adelaide coma scale (ACS), which is stated as follows:Best Eye Response (as in adult scale):Spontaneous – 4To speech – 3To pain – 2No response – 1Best Verbal Response:Oriented – 5Words – 4Vocal sounds – 3Cries – 2No response – 1Best Motor Response (as in adult scale):Obeys commands – 5Localises pain – 4Flexion to pain – 3 Extension to pain – 2No response – 1 The described child scores:Eye response – 1| Verbal response – 3| Motor response – 4Thus, bringing the total ACS score to 8.

Atopic dermatitis is an allergic condition which is more apparent in those children who have a positive family history in their 1st or 2nd degree relatives. In some cases, there might be a positive history of bronchial asthma. The best treatment option in this case would be topical application of 1% hydrocortisone ointment to the affected areas of the child. We cannot prescribe a strong ointment to the face because it may lead to skin atrophy, telangiectasia and other steroid related topical complications.

Inhaled objects are more likely to enter the right lung for several reasons. First the right bronchus is shorter, wider and more vertical than the left bronchus. Also, the carina (a ridge-like structure at the point of tracheal bifurcation) is set a little towards the left. The terminal bronchiole is a very small space and impossible for the seed to lodge here.

To get more information regarding hearing loss, a physician should perform both Rinne and Weber tests. Weber test alone cannot tell which side is affected.Rinne test – a vibrating tuning fork (typically 512 Hz) is placed initially on the mastoid process behind each ear until sound is no longer heard. Then, without re-striking the fork, the fork is then quickly placed just outside the ear with the patient asked to report when the sound caused by the vibration is no longer heard. A normal or positive Rinne test is when sound is still heard when the tuning fork is moved to air near the ear (air conduction or AC), indicating that AC is equal or greater than (bone conduction or BC).Weber’s test – tuning fork is placed in the middle of the forehead equidistant from the patient’s ears. The patient is then asked which side is loudest. In unilateral sensorineural deafness, sound is localised to the unaffected side however in unilateral conductive deafness, sound is localised to the affected side.

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

According per the national guidelines, 5 inflation breaths should be given with a gas pressure of 30cmH2O for term babies. Each breath should be given for 2-3 seconds. Pre-term babies should be aerated with a lower pressure of 20-25cmH2O.

This is a case of an anaphylactic reaction that requires immediate intervention. IM adrenaline dose for 6-12 year old children is 300 micrograms IM.

Cricothyroidectomy is done in life threatening condition, where an incision is made in cricothyroid membrane to establish a patent airway.

Prepubertal atrophic vaginitis is due to a lack of vaginal oestrogen. The pathophysiology behind prepubertal atrophic vaginitis:1.The proximity of the vagina to the anus2.Lack of oestrogen – leads to thinning of the vaginal mucosa3.Lack of pubic hair to protect the area4.Lack of labial fat pads

The most probable diagnosis for this patient would be a duplex kidney with an ectopic ureter inserting below the bladder neck. Rationale: The Weigert-Myer law states that the upper moiety ureter inserts inferior and medial to the lower moiety ureter. Other options:- Horseshoe kidney would display as a single pelvic kidney on an ultrasound scan.- Ureterocele would be a cystic lesion within the bladder or may prolapse at birth. – Continence should not be affected by polycystic kidney disease. – The overactive bladder would cause frequency and urgency, neither of which is mentioned in the history.

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.

Diabetes ketoacidosis is one of the most serious and acute complications of diabetes. At the time of presentation and during treatment of diabetic ketoacidosis (DKA), several metabolic and electrolyte derangements can ultimately result in respiratory compromise. Most commonly, hypokalaemia, hypomagnesemia and hypophosphatemia can eventually lead to respiratory muscles failure. Furthermore, tachypnoea, hyperpnea and more severely, Kussmaul breathing pattern can develop. Also, hydrostatic and non-hydrostatic pulmonary oedema can occur secondary to volume shifts into the extracellular space and secondary to increased permeability of the pulmonary capillaries. The presence of respiratory failure in patients with DKA is associated with higher morbidity and mortality. Being familiar with the causes of respiratory compromise in DKA, and how to treat them, may represent better outcomes for patients with DKA.

Scurvy is a condition caused by a dietary deficiency of vitamin C, also known as ascorbic acid. Humans are unable to synthesize vitamin C, therefore the quantity of it that the body needs has to come from the diet. The presence of an adequate quantity of vitamin C is required for normal collagen synthesis. In scurvy bleeding tendency is due to capillary fragility and not coagulation defects, therefore blood tests are normal.

Measles and chickenpox are spread by droplets. Thus, patients should be isolated. Rheumatic fever and post-streptococcal glomerulonephritis are immune mediated diseases that don’t require isolation. Herpetic gingivostomatitis spreads by direct transmission of infected secretions to the stratified squamous epithelium. HSP is not an infectious disease.

Penetrance is defined as the percentage of individuals having a particular mutation or genotype who exhibit clinical signs or phenotype of the associated disorder or genotype.Gaucher disease is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

Milestones of 12-month-old child are as follows:Social and Emotional- Is shy or nervous with strangers- Cries when mom or dad leaves- Has favourite things and people camera- Shows fear in some situations- Hands you a book when he wants to hear a story- Repeats sounds or actions to get attention- Puts out arm or leg to help with dressing – Plays games such as “peek-a-boo” and “pat-a-cake” Language/Communication- Responds to simple spoken requests- Uses simple gestures, like shaking head “no” or waving “bye-bye”- Makes sounds with changes in tone (sounds more like speech)- Says “mama” and “dada” and exclamations like “uh-oh!”- Tries to say words you sayCognitive (learning, thinking, problem-solving)- Explores things in different ways, like shaking, banging, throwing- Finds hidden things easily- Looks at the right picture or thing when it’s named- Copies gestures- Starts to use things correctly| for example, drinks from a cup, brushes hair- Bangs two things together- Puts things in a container, takes things out of a container- Lets things go without help- Pokes with index (pointer) finger – Follows simple directions like “pick up the toy”Movement/Physical Development- Gets to a sitting position without help – Pulls up to stand, walks holding on to furniture (“cruising”)- May take a few steps without holding on- May stand alone

A three-year child’s typical developmental milestones include walking up and down the stairs with alternating feet, jumping in a place with two feet together, and jumping forward for about 2 feet. The child can pedal a tricycle and can throw a ball over and underhand. An average child should start walking around 12-14 months of age and should be investigated as early as 18 months if they do not begin to walk. Skipping can be done by a child of 5 years of age. A child of 6-7 years of age can ride a bike with stabilizers and can balance on one foot for 20 seconds.

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.

Most infants have a good heart rate after birth and establish breathing by about 90 s. If the infant is not breathing adequately aerate the lungs by giving 5 inflation breaths, preferably using air. Until now the infant’s lungs will have been filled with fluid.

Cystic fibrosis is an autosomal recessive inherited disorder that affects the lungs or the pancreas. In the case of an affected child whose parents do not have the disorder but carry one copy of the mutated gene, each sibling has a 50% chance of being a carrier of the disease. They can inherit one copy of the gene from each parent. There is a 25 % chance that the child may inherit both mutated genes and be homozygous for the trait.
