Jaundice in a new-born on the day of delivery is most likely due to Rh incompatibility. This occurs when the mother is Rh-negative and the baby is Rh-positive. Antibodies in the mother against the Rh factor in the baby will destroy the red blood cells in the baby, increasing the bilirubin in the blood. Breast milk jaundice and Galactosemia do not occur immediately after birth, and congenital rubella syndrome and formula feeding does not cause jaundice in babies.

Tinea corporis is a type of dermatophytosis, caused by Trichophyton or Microsporum. The disease is highly contagious and rapidly spreads to all the areas of the body, including the glabrous skin. It produces an erythematous itchy skin rash with a central area of clearance surrounded by raised scaly borders. Lesions can appear as concentric circles that overlap, referred to as tinea imbricate.

The most appropriate procedure in the surgical management of this child would be to perform an appendicostomy for anterior continence enemas (Malone procedure).Idiopathic constipation leading to faecal incontinence is managed in a stepwise progression, first with laxatives such as movicol, enemas and stronger laxatives and in younger children inter-sphincteric injection of botox may be performed. Following this either anal irrigation or antegrade continence enemas are performed. Appendicostomy for anterior continence enemas allow colonic washouts and thereby rapid achievement of continence.Other options:- Defunctioning Ileostomy: Although an option in extreme cases, an ACE stoma would be more appropriate in this child.- Laparotomy for resection of the megarectum is performed if ACE stoma fails due to megarectum.- Left hemicolectomy is a procedure reserved for slow-transit colons to increase transit time.- Bishop-Koop stoma: It is a procedure of historical significance. It is a way of washing out and managing meconium ileus.

The most probable diagnosis for this patient, according to the clinical scenario provided is tuberous sclerosis. It is an autosomal-dominant disorder characterised by hamartomas located throughout the body, often prominently involving the central nervous system and skin. Two loci on chromosomes 9 and 16 have been identified to be associated with this condition. The condition has a variable expression and penetrance and is further characterised by:- Seizures (usually infantile spasms)- Developmental delay- Facial/cutaneous angiofibromas (adenoma sebaceum)- Periungual fibromas (pink projections from the nail folds)- Shagreen patches (leathery thickenings of the skin usually on the back) – Ash leaf macules (areas of depigmentation that become visible under a Wood’s light)- Fundoscopy may reveal white streaks along the fundal vessels.

Epiglottitis is characterized by the abrupt onset of severe symptoms. Without airway control and medical management, symptoms may rapidly progress to respiratory obstruction and death in a matter of hours.Usually, no prodromal symptoms occur in children. Fever is usually the first symptom, and temperatures often reach 40°C. Acute epiglottitis may result in sudden, complete upper airway obstruction. Classic signs in children are four D’s: drooling, dyspnoea, dysphagia, and dysphonia.

Lesions caused by herpes simplex virus may appear in various clinical stages. They are usually the result of an HSV-1 infection and they may appear on the face and neck. They start as fluid-filled blisters which eventually erupt into small painful ulcers.

The sign being elicited in this patient is Nikolsky’s sign. Based on the findings, the patient is suffering from toxic epidermal necrolysis.Nikolskys sign: Rubbing the skin causes exfoliation of the outer layer and usually blistering within a few minutes. Other options:- Cullen’s sign: Periumbilical bruising due to intra-abdominal haemorrhage. If the discolouration is seen in the flanks, it is called Cullen’s sign. Underlying pathology includes ruptured ectopic pregnancy and haemorrhagic pancreatitis. – Forscheimer’s sign: It is a fleeting exanthem that is seen as small, red spots (petechiae) on the soft palate. Associated with rubella and glandular fever. Gorlin’s sign: It is the ability to touch the tip of the nose with the tongue. Increased incidence in children with connective tissue disorder, e.g. Ehler Danlos syndrome. – Auspitzs sign: These are small bleeding points are left behind when psoriatic scales are lifted off. It is not a very sensitive or specific sign. Other cutaneous signs include:- Hair collar sign: It is a collar of hypertrichosis around an area of cranial dysraphism.- Hertoghe’s sign (Queen Anne’s sign): It is the loss of lateral one-third of eye-brows. It is associated with numerous conditions, including lupus, HIV, and hypothyroidism. – Dariers sign: It is the swelling, itching and erythema that occurs after stroking skin lesions of a patient with systemic mastocytosis or urticarial pigmentosa. – Dermatographism: Rubbing the skin causes a raised, urticarial lesion. – Koebners phenomenon: It is the appearance of new skin lesions in areas of trauma.- Breakfast, lunch, and dinner sign: Linear pathway of a group of three to five papules caused by the common bed bug, Cimex lectularius. – Buttonhole sign: In type 1 neurofibromatosis, neurofibromas can be invaginated with the finger back into the subcutis. The nodule will reappear after the release of pressure. The sign is also positive for dermatofibromas. – Crowe’s sign: Axillary freckling seen in type I neurofibromatosis.

Wolff-Parkinson-White (WPW) syndrome is a pre-excitation syndrome characterised by re-entry tachycardia that most commonly presents as a recurrent supraventricular tachycardia. ECG will show a short PR interval and a prolonged QRS complex.

There are four types of IVH. These are called grades and are based on the degree of bleeding.Grades 1 and 2 involve a smaller amount of bleeding. Most of the time, there are no long-term problems as a result of the bleeding. Grade 1 is also referred to as germinal matrix haemorrhage (GMH).Grades 3 and 4 involve more severe bleeding. The blood presses on (grade 3) or directly involves (grade 4) brain tissue. Grade 4 is also called an intraparenchymal haemorrhage. Blood clots can form and block the flow of cerebrospinal fluid. This can lead to increased fluid in the brain (hydrocephalus).

Retinopathy of prematurity (ROP) affects premature infants. It is a retinal vasoproliferative disease for which current screening guidelines are primarily based on birth weight and gestational age. The disease is first detected by screening at 32-38 weeks of gestation or in infants that are about 6-7 weeks old. Screening consists of dilation of the pupils and observing for dilated vessel.

Based on the clinical scenario, the most probable diagnosis in this patient is Kallmann’s syndrome.Kallmann’s syndrome is due to isolated gonadotrophin-releasing hormone (GnRH) deficiency. It is often inherited in an X-linked recessive manner. Other options:- While Klinefelter’s syndrome is also associated with hypogonadism, the other clinical features of Klinefelter’s are not seen. – Cryptorchidism is ruled out by the presence of testes in the scrotum. – The presentation of the child is not suggestive of mumps orchitis or hyperprolactinaemia.

Rett syndrome is a disorder that affects the brain and occurs most commonly in girls. It presents with a period of normal development followed by severe problems with language and communication, learning, coordination, and other brain functions.

Topical treatments are useful in the treatment of mild Psoriasis, or as adjuvant therapy in ultraviolet and systematic treatments. These treatments include moisturisers, dithranol, coal tar, salicylic acid, topical immunomodulators such as calcineurin, topical retinoids, Vitamin D analogues and topical steroids. Topical steroids are known to have a number of side effects such as striae, atrophy of the skin, telangiectasia, acneiform rash, and easy bruising. Localised pustular psoriasis is also associated with topical steroids in higher doses. Use of more than 500 g of hydrocortisone or 50 g clobetasol propionate have been shown to suppress adrenal function. Calcitriol, a vitamin D analogue, is only available as an ointment and does not stain clothes and skin the way dithranol and coal tar are known to.

The murmur and thrill indicate a right outflow tract murmur, coupled with the right ventricular heave suggests right ventricular hypertrophy. The VSD would not have been amenable to surgery due to the child’s size/weight and so instead would have been palliated with a PA band. As the child grows, this band progressively restricts pulmonary blood flow until the left to right shunt has reversed. Then it is time for the band to be removed and the VSD to be closed.Pulmonary atresia is a cyanotic condition, which may be palliated with an arterial duct stent. This answer is incorrect as the stent placement would not require a midline sternotomy and would give a continuous machinery type murmur. Pulmonary stenosis with PDA ligation is incorrect. The murmur, thrill, and heave all match a pulmonary stenosis but in the absence of an additional shunt lesion the child would not be cyanosed.

Marfan syndrome is a disorder that affects the connective tissue found throughout the body, Marfan syndrome can affect many systems, often causing abnormalities in the heart, blood vessels, eyes, bones, and joints. The two primary features of Marfan syndrome are vision problems caused by a dislocated lens (ectopia lentis) in one or both eyes and aortic root disease, leading to aneurysmal dilatation, aortic regurgitation and dissection is the main cause of morbidity and mortality in Marfan syndrome.

PARACHUTE REFLEX: This reflex occurs in slightly older infants when the child is held upright and the baby’s body is rotated quickly to face forward (as in falling). The baby will extend his arms forward as if to break a fall, even though this reflex appears long before the baby walks.Newborn reflexes are:Rooting reflex:This reflex starts when the corner of the baby’s mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.Suck reflex:Moro reflex:The Moro reflex is often called a startle reflex. That’s because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound, the baby throws back his or her head, extends out his or her arms and legs, cries, then pulls the arms and legs back in. This reflex lasts until the baby is about 2 months old.Tonic neck reflex:When a baby’s head is turned to one side, the arm on that side stretches out and the opposite arm bends up at the elbow. This is often called the fencing position. This reflex lasts until the baby is about 5 to 7 months old.Grasp reflex:Stroking the palm of a baby’s hand causes the baby to close his or her fingers in a grasp. The grasp reflex lasts until the baby is about 5 to 6 months old. A similar reflex in the toes lasts until 9 to 12 months.Stepping reflex:This reflex is also called the walking or dance reflex because a baby appears to take steps or dance when held upright with his or her feet touching a solid surface. This reflex lasts about 2 months.

In the Hirschberg test, the corneal reflex should fall in the same place in both eyes. If there is a malalignment then the reflection of the light will appear in different places in the two eyes. The cover test is then used to differentiate between a latent deviation, or a manifest deviation.In the Bruckner test, the direct ophthalmoscope is used to obtain a red reflex simultaneously in both eyes. If strabismus is present, the deviated eye will have a lighter and brighter reflex than the fixating eye.The swinging flashlight test is a test of the pupils response to light, and to check for a relative afferent pupillary defect (RAPD).The Angle Kappa test measures the angle between the line of sight and the corneal-pupillary axis. It is a monocular measurement.

Intussusception is one of the common causes of intestinal obstruction in children, resulting from the invagination or telescoping of one segment of the bowel into the other distal segment. It may induce bowel ischemia and necrosis, as well. It can occur as a complication of Meckel’s diverticulum. It usually occurs proximal to the ileocecal valve, and the most common presentation is ileocecal. Early signs and symptoms include cramping abdominal pain, nausea, vomiting, and pulling legs up to chest area. First line treatment includes resuscitation with IV fluids and nasogastric tube. It responds well to air-enema, which is also diagnostic.

The most probable diagnosis based on the scenario provided above is hereditary spherocytosis.While jaundice and abdominal pain might make you think of hepatitis or cholecystitis in the first instance, the lack of fever suggests otherwise. The apyrexial presentation is against acute cholecystitis, and the past medical history reveals a chronic type of fatigue and two previous episodes of hepatitis. Furthermore, it is unlikely that the child has contracted infective hepatitis twice and now a third time! The most common cause of hepatitis in childhood is hepatitis A, however the lack of travel history to endemic areas makes this less likely. Hepatitis A is usually a mild, self-limiting disease that never presents with chronic symptoms. The chronicity of his fatigue and the blood results lead towards a haematological diagnosis. This is further substantiated by his low haemoglobin levels, high MCV and high reticulocyte count. Chronic haemolytic anaemia is the most likely cause, and the negative Coombs excludes autoimmune haemolytic anaemia (AIHA). Thus, leaving us with the answer as hereditary spherocytosis.Hereditary spherocytosis is a disorder that makes the cytoskeleton of red cells more fragile and therefore leads to red cell death and splenomegaly. Gallstones are a result of this red cell destruction and increased haem metabolism.

A patient with Down’s syndrome is likely to be subfertile rather than infertile.Down’s syndrome:The clinical features of Down’s syndrome include:- Face: upslanting palpebral fissures, epicanthic folds, Brushfield spots in iris, protruding tongue, small ears, and round/flat face- Flat occiput- Single palmar crease, pronounced ‘sandal gap’ in the first interdigital space of the feet.- Hypotonia- Congenital heart defects (40-50%)- Duodenal atresia- Hirschsprung’s diseaseThe cardiac complications in these patients include:- Endocardial cushion defect (40%)- Ventricular septal defect (30%)- Secundum atrial septal defect (10%)- Tetralogy of Fallot (5%)- Isolated patent ductus arteriosus (5%)The complications that occur later in the life of the patient include:- Subfertility: Males are almost always infertile due to impaired spermatogenesis. Females, however, are usually subfertile and have an increased incidence of problems with pregnancy and labour.- Learning difficulties- Short stature- Repeated respiratory infections (+hearing impairment from glue ear)- Acute lymphoblastic leukaemia- Hypothyroidism- Alzheimer’s disease- Atlantoaxial instability

A supracondylar humerus fracture is a fracture of the distal humerus just above the elbow joint. The fracture is usually transverse or oblique and above the medial and lateral condyles and epicondyles. This fracture pattern is relatively rare in adults, but is the most common type of elbow fracture in children. They are historically associated with morbidity due to malunion, neurovascular complications, and compartment syndrome. Important arteries and nerves ( median nerve, radial nerve, brachial artery, and ulnar nerve) are located at the supracondylar area and can give rise to complications if these structures are injured. Most vulnerable structure to get damaged is Median Nerve. Damage/occlusion of the brachial artery is the cause of an absent radial pulse.

From the given scenario, the extraocular muscle affected in the child is superior oblique muscle. Point to remember:All of the extraocular muscles are supplied by the oculomotor nerve (3rd cranial nerve), except superior oblique (trochlear nerve/4th cranial nerve) and lateral rectus (abducens nerve/6th cranial nerve).The superior oblique muscle causes the eye to move downwards and medially. The unopposed inferior oblique, in this case, causes the eye to deviate upwards and medially. Children tend to tilt their head (torticollis) to the side opposite to the affected eye with their chin down toward the shoulder, and their face turned away from the affected side to decrease the diplopia.

The most probable cause for the patient’s presenting symptoms is Sarcoptes scabeii.Scabies:The boy in the scenario presents with a pruritic rash affecting the palms of the hands, especially in the web spaces between the fingers. Additionally, the fact that his sister is showing similar symptoms is an indication of its infectivity. The female Sarcoptes scabiei var hominis mite burrows into the webs of fingers and the sides of digits as seen in the child.This parasitic skin infestation presents typically with nocturnal itching. Other options:- Herpes simplex virus type 1 (HSV-1): This can affect this age group but would usually present with a vesicular perioral rash with associated erythema. – Human papillomavirus (HPV): Cutaneous human papillomavirus infection causes warts, which can form a dome and fleshy shaped lesions on the palms of the hands, but these are not usually itchy. Similar to the causative agent in the boy, they are contagious.- Poxvirus: These viruses cause molluscum contagiosum which presents as dome-shaped lesions anywhere on the body, rather than specifically in palms of hands or finger webs as seen in the boy. Poxviruses are also very infectious.- Staphylococcal infection: This causes impetigo, which presents with yellow discharge and underlying erythema. Impetigo is not usually itchy and can present on any part of the body, rather than the specific areas seen in the boy.

The external auditory canal (EAC) extends from the auricle to the tympanic membrane. Its lateral portion is fibrocartilaginous and its medial portion is bony. Its bony portion is formed by the tympanic portion of the temporal bone.

At the age of 18 months, Gertrude should be able to follow a one step command. At this age she would also be capable of putting words together in 1 or 2 word phrases, scribbling, throwing a ball, and building a tower of four cubes. At 2 she should be able to feed herself with a spoon or a fork, copy a vertical line, ride a tricycle, kick a ball and balance on one foot. Activities such as jumping will follow later on in her development at 3 years.

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 combination of cholestasis, congenital heart disease (mainly affecting the pulmonary vasculature) and anterior-segment abnormalities (primarily posterior embryotoxon) suggests a diagnosis of Alagille syndrome. Clinical features:The facial features are characteristic and include a prominent forehead, deep-set eyes and a pointed chin. The most common skeletal manifestation is butterfly vertebrae, a clefting abnormality of the vertebrae most often seen in the thoracic spine and described in up to 87% of cases. Radio-ulnar synostosis and short phalanges have also been described in Alagille but less frequently. Note: Pectus excavatum is a feature of Noonan syndrome, one of the differential diagnoses of pulmonary valve disease.

Congenital hypothyroidism is one of the most important diseases of the new-born, which may lead to mental and physical retardation when treatment is delayed or an appropriate dosage of thyroxine is not administered. The most alarming and earliest sign is jaundice, especially when it is prolonged, during the neonatal period.

The selection process is based on five requirements and essentially aims to select a random representative cohort through:1.Isolating a group for which there is a greater or lesser chance of detecting a possible difference between the treatments compared|2.Establishing a homogeneous group in order to reduce the variability of response, thus making statistical comparison more sensitive and decreasing the risk of bias due to the constitution of non-homogeneous groups|3.Obtaining representative samples of the affection studied|4.Defining the rules corresponding to realistic recruitment|5.Respecting ethical obligations.

Epilepsy is a common paediatric neurologic disorder characterized by seizures of varying frequency and intensity. There are many childhood or infantile epilepsy syndromes that can be categorized as benign epilepsy syndromes as the child suffering from these usually outgrows them after reaching a certain age, and they do not lead to significant cognitive or physical impairment. Some of these may not need any treatment. Such benign epilepsy syndromes include benign rolandic epilepsy, Panayiotopoulos syndrome, Gastaut type-idiopathic childhood occipital epilepsy, and idiopathic photosensitive occipital lobe epilepsy. West syndrome, also called infantile spasms, is a serious infantile epileptic encephalopathy, characterized by multiple clusters of myoclonic spasms, and regression of the previous normally attained milestones. It is associated with severe cognitive and physical impairment, often leading to life long disability.
