EPICure is a series of studies of survival and later health among babies and young people who were born at extremely low gestations – from 22 to 26 weeks.Boost II is a double-blind randomised controlled trial (RCT) comparing the effects of targeting arterial oxygen saturations between 85% and 89% versus 91% and 95% in preterm infants.OSCAR Xe is not the name of a study. Baby-OSCAR is an RCT to determine whether a confirmed large patent ductus arteriosus in very premature babies should be treated with ibuprofen within 72 hours of birth.SafeBoosC is a trial to examine if it is possible to stabilise the cerebral oxygenation of extremely preterm infants in the first 72 hours of life with the use of NIRS oximetry and a clinical treatment guideline. TOBY Xe is an RCT looking at the neuroprotective effects of hypothermia combined with inhaled xenon following perinatal asphyxia.

The clinical presentation is suggestive of congenital rubella syndrome. The classic triad of presenting symptoms includes sensorineural hearing loss, ocular abnormalities (cataract, infantile glaucoma, and pigmentary retinopathy) and congenital heart disease (patent ductus arteriosus and pulmonary artery stenosis). Other findings in congenital rubella syndrome include CNS abnormalities (mental retardation, behavioural disorders, encephalographic abnormalities, hypotonia, meningoencephalitis, and microcephaly), hepatosplenomegaly, and jaundice.

Intussusception is a condition in which one segment of intestine telescopes inside of another, causing an intestinal obstruction. Although intussusception can occur anywhere in the gastrointestinal tract, it usually occurs at the junction of the small and large intestines. Most describe the symptoms of intussusception as a triad of colicky abdominal pain, bilious vomiting, and currant jelly stool. The primary symptom of intussusception is described as intermittent crampy abdominal pain.

The most probable diagnosis in this patient is lead poisoning.Lead poisoning: While it is not common, it can be potentially fatal. One of the key presenting features here is pica, the ingestion of non-nutritive substances such as soil, soap, paper or wood. Pica can also be observed in children in iron-deficiency anaemia, developmental delay and pregnancy. However, in a child who is exposed to lead in their environment (e.g. from lead paint or pipes), lead poisoning is most likely. It is commonly associated with iron deficiency which in turn increases the lead absorption. Treatment is either with oral D-penicillamine or intravenous sodium calcium edetate.

Among the options provided, zidovudine causes lipoatrophy as a side effect.Zidovudine: Although both hypertrophy and atrophy are described related to HIV medications, nucleoside reverse transcriptase inhibitor (NRTIs) such as zidovudine and stavudine are closely associated with fat loss.Other options:- Enfuvirtide is an HIV-fusion inhibitor. Lipoatrophy is not commonly associated with this drug.- Efavirenz is an NNRTI, which is not associated with lipoatrophy. Common side effects include neuropsychiatric effects, rash and nausea. – Ganciclovir is not an anti-HIV medication and is used for cytomegalovirus (CMV) infections.- Raltegravir is an integrase inhibitor and is associated with fat gain.

Vesicoureteral reflux is a common disorder in children but can result in kidney scarring following acute pyelonephritis. The gold standard diagnostic test to detect renal scars in children is 99mTc-dimercaptosuccinic acid (DMSA) scintigraphy

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.

Syphilis is an infectious venereal disease caused by the spirochete Treponema pallidum. Syphilis is transmissible by sexual contact with infectious lesions, from mother to foetus in utero, via blood product transfusion, and occasionally through breaks in the skin that come into contact with infectious lesions. If untreated, it progresses through 4 stages: primary, secondary, latent, and tertiary. Primary and secondary syphilis are easy to treat with a penicillin injection. Penicillin is one of the most widely used antibiotics and is usually effective in treating syphilis. People who are allergic to penicillin will likely be treated with a different antibiotic, such as:doxycyclineazithromycinceftriaxone

The child has symptoms and signs suggestive of an inflammatory arthropathy. This is why he should firstly be referred for an eye exam to exclude iritis or treat it if present. – Amblyopia is not directly associated with inflammatory arthropathies unless they had recurrent ocular involvement.- Blepharitis is not an associated finding in a child with inflammatory arthropathy.- Episcleritis may occur, and is often non-sight threatening, and therefore would not be the main cause for concern.- Optic neuropathy in juvenile inflammatory arthritis has been reported, although it is rare.

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.

The signs and symptoms of vitamin D-dependent rickets begin within months after birth, and most are the same for all types of the condition. The weak bones often cause bone pain and delayed growth and have a tendency to fracture. When affected children begin to walk, they may develop abnormally curved (bowed) legs because the bones are too weak to bear weight. Impaired bone development also results in widening of the metaphysis, especially in the knees, wrists, and ribs. Some people with vitamin D-dependent rickets have dental abnormalities such as thin tooth enamel and frequent cavities. Poor muscle tone (hypotonia) and muscle weakness are also common in this condition, and some affected individuals develop seizures.

From the given clinical scenario, the peroxisomal disorder in question is Refsum’s disease.It is characterised by anosmia, early-onset retinitis pigmentosa (night blindness), chronic ataxia, variable neuropathy, deafness and ichthyosis. It is an inherited disorder of fatty acid oxidation with phytanic acid accumulation in the blood and tissues. This leads to the motor and sensory neuropathy. Other options:- Loss of sensation in extremities, dysarthria and diabetes is suggestive of Friedrich’s Ataxia. It is the most common autosomal recessive cause of ataxia. Associated features include dysarthria, scoliosis, diabetes and hypertrophic cardiomyopathy. – Numbness of the limbs, seizures and developmental delay suggests mitochondrial cytopathy such as NARP (Neuropathy, Ataxia and Retinitis Pigmentosa). Learning difficulties, developmental delays and convulsions are not uncommon, as with many mitochondrial disorders. – Rapid, chaotic eye movements, behaviour change and irritability, suggest opsoclonus-myoclonus syndrome. It is thought to be a Para infectious or paraneoplastic condition (secondary to neuroblastoma) linked to an abnormal immune response. Children present unwell with altered behaviour, irritability, ataxia, random chaotic eye movements and later myoclonus. – Sweet-smelling urine, lethargy and seizures suggest Maple Syrup Urine Disease (MSUD). It is an autosomal recessive organic acidaemia. There is a distinct sweet odour to the urine of affected individuals, particularly at times of acute illness. Without treatment, MSUD can lead to seizures, brain damage, coma and death. The most common and classic form affects babies shortly after birth, but variant forms may not be evident until later childhood.

The spinal muscular atrophies (SMAs) comprise a group of autosomal recessive disorders characterized by progressive weakness of the lower motor neurons. several types of spinal muscular atrophies have been described based on age when accompanying clinical features appear. The most common types are acute infantile (SMA type I, or Werdnig-Hoffman disease), chronic infantile (SMA type II), chronic juvenile (SMA type III or Kugelberg-Welander disease), and adult-onset (SMA type IV) forms.SMA type I – Acute infantile or Werdnig-Hoffman diseasePatients present before 6 months of age, with 95% of patients having signs and symptoms by 3 months. They have severe, progressive muscle weakness and flaccid or reduced muscle tone (hypotonia). Bulbar dysfunction includes poor suck ability, reduced swallowing, and respiratory failure. Patients have no involvement of the extraocular muscles, and facial weakness is often minimal or absent. They have no evidence of cerebral involvement, and infants appear alert.Reports of impaired fetal movements are observed in 30% of cases, and 60% of infants with SMA type I are floppy babies at birth. Prolonged cyanosis may be noted at delivery. In some instances, the disease can cause fulminant weakness in the first few days of life. Such severe weakness and early bulbar dysfunction are associated with short life expectancy, with a mean survival of 5.9 months. In 95% of cases, infants die from complications of the disease by 18 months.

The clinical presentation and way the boy ‘climbs up’ his legs to get up from a supine position (Gowers’ sign) suggests proximal muscle weakness secondary to dermatomyositis.Dermatomyositis is an inflammatory myopathy that typically presents between the ages of five years and ten years. The onset is insidious, and the proximal muscle weakness and raised creatine kinase might be mistaken for muscular dystrophy. However, the systemic illness and rash are characteristic features of the condition.

Minimal-change disease (MCD) refers to a histopathologic glomerular lesion, typically found in children, that is almost always associated with nephrotic syndrome. The most noticeable symptom of MCD is oedema, which can develop very rapidly. Due to the renal loss of proteins muscle wasting and growth failure may be seen in children. Renal function is usually not affected and a proteinuria of more than 40 mg/h/m2 is the only abnormal finding in urinalysis.

The sensory innervation of the external auditory meatus is provided by branches of several cranial nerves. The auriculotemporal branch of the mandibular nerve (CN V3) with the nerve to external acoustic meatus supplies the anterior and superior wall of the canal with sensory innervation. The auricular branch of the vagus nerve (CN X) supplies the posterior and inferior walls of the canal, and the facial nerve (CN VII) may also supply it due to its connection with the vagus nerve.

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.

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.

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.

Increasing the volume of the TV and the child’s loss of hearing may suggest that he has otitis media with effusion but the fever and the ear pain and fever strongly points to otitis externa as the diagnosis.

ABC : Airway, breathing, circulation is the order of assessment in any patient that is unconscious and apnoeic.

The most common cause of homonymous hemianopia (HH) is a stroke. In this condition there is bitemporal field loss. Lesions posterior to the optic chiasm, in the brain parenchyma are most likely to be the cause of the HH. In this case the retention of central vision indicates that the area of injury may be in the occipital cortex, sparing the occipital pole. The occipital pole receives sensory fibres from the macular, and has a dual blood supply protecting it from total infarction. Lesions of the optic tract can be ruled out as these cause total vision loss in the affected eye. Parietal or temporal nerve lesions cause affect the inferior and superior parts of the visual field respectively causing homonymous quadrantinopias.

Developmental dysplasia of the hip (DDH) is a spectrum of anatomical abnormalities of the hip joint in which the femoral head has an abnormal relationship with the acetabulum.Plain radiographs are of limited value for diagnosis in the new-born child because the femoral head and acetabulum are largely cartilaginous. Ultrasound scanning is the investigation of choice to evaluate DDH in infants younger than six months of age and is useful to diagnose more subtle forms of the disorder when a clinical exam is equivocal. It is also the only imaging modality that enables a three-dimensional real-time image of a neonate’s hip.

Diazepam given rectally may be helpful in treating prolonged convulsions outside and within hospital when intravenous injection is not possible. A rectal dose of 0.5 mg/kg (maximum 10 mg) of injectable diazepam, undiluted or diluted with a 50% propylene glycol solution, can stop seizures in up to 80% of children. There are few adverse reactions. Seizures in children usually cease spontaneously within 5-10 minutes and are rarely associated with significant sequelae. The chance of a seizure stopping spontaneously decreases significantly after 10-15 minutes. Similarly, the efficacy of anticonvulsant medication decreases after 10-15 minutes of fitting and the risk of adverse effects increases. Convulsive seizures lasting longer than 30 minutes constitute status epilepticus and may be complicated by cardio respiratory depression and brain injury. Diazepam or clonazepam, given intravenously, is generally the drug of choice for the emergency treatment of convulsive status epilepticus. Intravenous diazepam may be difficult to administer to the young convulsing child and, because of the need for intravenous access, is not ideal for rapid treatment in the community by non-medical carers.

The patient is most likely suffering from obstructive jaundice. Ultrasound of the abdomen is the superior diagnostic tool in detecting and assessing biliary system obstruction, because it is easy, available, accurate and non-invasive.

Arterial blood gas is useful for the evaluation of oxygen and carbon dioxide gas exchange, respiratory function including hypoxia, and acid/base balance. This will quickly indicate if assisted ventilation is required for this patient.

Pityriasis amiantacea: This condition is characterized by thick, asbestos-like scales on the scalp and is often associated with psoriasis or seborrheic dermatitis.

Infantile seborrhoeic dermatitis: Also known as cradle cap, this condition causes greasy, yellowish scales on the scalp.

Tinea capitis: A fungal infection of the scalp that leads to scaling, hair loss, and sometimes redness and swelling.

Cutaneous lupus erythematosus: While lupus can cause skin lesions, it is less commonly associated with a scaly scalp compared to the other conditions listed. It can cause hair loss and erythema, but significant scaling is not a primary feature.

Scalp psoriasis: This condition is well-known for causing thick, silvery scales on the scalp

Coarctation of the aorta is one of the serious forms of congenital heart diseases characterized by a congenitally narrowed down proximal thoracic aorta. This narrowing is usually located distal to the origin of the left subclavian artery. Coarctation can occur in isolation but can accompany other cardiac lesions, including a bicuspid aortic valve. When the coarctation is located just above the left subclavian artery, raised blood pressure can be noted in the right arm. The most common type of murmur found in coarctation of the aorta is a diastolic murmur of aortic regurgitation due to the presence of a bicuspid aortic valve. Exercise augmented cardiac output is only affected in cases where coarctation of the aorta leads to heart failure. Hypertension persists even after the surgical repair and needs to be closely monitored.

In the first few years of life the developing sensory inputs are important. Hearing is essential for speech and language development and may be delayed when a child cannot hear. Therefore any child with a family history of hereditary deafness should be screened. From about 4-6months babies are able to laugh and babble when excited or unhappy. By the age of 9 months the child should be able to bring together groups of same sound syllables and be able to say one or two words by the 1st birthday. If a child is unable to babble by 10-12 years, it may indicate hearing impairment. By the age of 2 a child should be able to speak in 1 or 2 word phrases and often repeats phrases used by others, known as Echolalia.

External oblique forms the outermost muscle of the three muscles comprising the anterolateral aspect of the abdominal wall. Its aponeurosis comprises the anterior wall of the inguinal canal.
