Based on the findings presented, the sign elicited is Rovsing’s sign.Rovsing’s sign:It is a sign suggestive of appendicitis. A positive sign is determined when palpation in the left lower quadrant of a patient’s abdomen causes pain in the right lower quadrant.Other options:- Murphy’s sign is positive in gallbladder inflammation. With the upper border of the examiner’s hand in the right upper quadrant of the abdomen under the rib cage, the patient is asked to inhale. Inhalation causes the gallbladder to descend, which catches on the fingers, causing pain.- Cullen’s sign is suggestive of ectopic pregnancy or acute pancreatitis and describes the bruising around the umbilicus.- Tinel’s sign is positive in those with carpal tunnel syndrome. The examiner’s fingers tap the median nerve over the flexor retinaculum, which causes paraesthesia over the distribution of the median nerve.- Battles’ sign describes bruising behind the ear, suggesting a basal skull fracture of the posterior cranial fossa.

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.

A lymphangioma is a swelling or mass that occurs mainly in the head, neck, and mouth. Lymphangiomas are the result of a congenital condition and are usually apparent at birth, or at least by the time a person is 2 years old. It is rare in adult population and when detected, it can be treated with surgical excision. Branchial cyst in most cases does not transilluminate which lymphangioma does.

Glandular fever (Infectious Mononucleosis) is caused by Epstein-Barr virus (EBV). Leucocytosis rules in infectious mononucleosis and thrombocytopenia is not an uncommon association. ESR is elevated in most of the cases. Paul-Bunnell test is a rapid test for infectious mononucleosis due to Epstein-Barr virus (EBV).

WHO states that diabetes can be diagnosed from a single fasting glucose of > 7.0 mmol/l with characteristic symptoms or a glucose level of > 11.1 mmol/l 2 hours after a glucose load. Two fasting glucose levels of > 7.0 mmol/l on separate occasions can also fit the diagnosis in the absence of characteristic symptoms.

Endothoracic fascia: the connective tissue (fascia) that is between the costal parietal pleura and the inner wall of the chest wall. Costomediastinal recess: the point where the costal pleura becomes mediastinal pleura. Costodiaphragmatic recess: is the lowest point of the pleural sac where the costal pleura becomes diaphragmatic pleura. Cupola: the part of the parietal pleura that extends above the first rib level into the root of the neck. Costocervical recess: this is a made-up term. Peritracheal fascia: a layer of connective tissue that invests the trachea.

Cot death also know as SIDS or Sudden Infant Death syndrome. Putting a baby to sleep on his back has been shown to reduce the risk of SIDS.

The azygos lobe is usually well seen on the chest radiograph, where it is limited by the azygos fissure, a fine, convex (relative to the mediastinum) line that crosses the apex of the right lung.

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.

Cortisol is secreted in a circadian pattern.The secretion of cortisol is regulated by the suprachiasmatic nucleus located in the hypothalamus.Other options:- FSH, LH, GH and prolactin are secreted in a pulsatile pattern, i.e. these hormones are secreted in an episodic manner rather than continuously.- Thyroxine is secreted in a continuous pattern, not pulsatile.- The secretion of ACTH is in response to stress.Secondary to stress, the hypothalamus secretes corticotrophin releasing hormones, which are transported to the pituitary gland via the hypophyseal-portal system. ACTH is then released by the pituitary gland and binds to its receptor on the adrenal gland, which releases cortisol.

According to APLS, your next step should be one of the following: synchronous DC shock, amiodarone, or cardiology advice for alternative antiarrhythmics.

Based on the clinical scenario provided, the most probable nerve injured in this patient would be the trochlear nerve. The trochlear nerve has a relatively long intracranial course, and this makes it vulnerable to injury in head trauma. Head trauma is the most frequent cause of acute fourth nerve palsy. A 4th nerve palsy is the most common cause of vertical diplopia. The diplopia is at its worst when the eye looks medially which it usually does as part of the accommodation reflex when walking downstairs.

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.

Tuner’s syndrome is not associated with arachnodactyly.Arachnodactyly is seen in the following conditions:- Marfan syndrome- Homocystinuria- Ehlers-Danlos syndrome- Congenital contractural arachnodactylyOther rare syndromes include:- Loeys-Dietz syndrome- Antley-Bixler syndrome- Marden-Walker syndrome- Lujan-Frinz syndrome- Haim-Munk syndrome- Marden-Walker syndrome- Spondylocostal dysostosis

Primary sclerosing cholangitis (PSC) is a long-term progressive disease of the liver and gallbladder characterized by inflammation and scarring of the bile ducts which normally allow bile to drain from the gallbladder. Early cholangiographic changes can include fine or deep ulcerations of the common bile duct. As PSC progresses, segmental fibrosis develops within the bile ducts, with saccular dilatation of the normal areas between them, leading to the typical beads-on-a-string appearance seen on cholangiography. Although these strictures can be found anywhere on the biliary tree, the intrahepatic and extrahepatic bile ducts are simultaneously involved in the vast majority of cases.

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.

Pulmonary surfactant is a mixture of lipids and proteins which is secreted by the epithelial type II cells into the alveolar space.

The management of cystic fibrosis requires a multidisciplinary approach, starting with a planned diet.The critical points of this management approach are:Chest physiotherapy and postural drainage – the parents are usually taught to do this.Deep breathing exercises,High calorie, high fat intake with vitamin supplementation.Pancreatic enzyme supplements with meals.Heart-lung transplantation would be the definitive treatment.Note: Previously, a high-calorie, low-fat diet was recommended to reduce steatorrhea. However, it is no longer the desired approach.

When a child with joint problems presents with red-eye, the likelihood of anterior uveitis must be excluded by involving an ophthalmologist in the assessment. This is because uveitis is the most common extra-articular manifestation of juvenile idiopathic arthritis.Other options:- Cataract: It does not give rise to a red-eye, but leukocoria. Often this would have been picked up at an earlier age. – A patient with a corneal foreign body almost would almost invariably give a suspicious history (onset while playing outdoors etc.), as well as have marked symptoms of ocular discomfort (red, watery and painful eyes). – A child with periorbital cellulitis often presents acutely unwell and distressed. – A child with an uncorrected refractive error often complains of being unable to see in class and does not normally present with ocular redness.

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.

Most cases of Trisomy 18, also called Edwards syndrome, are not inherited but occur as random events during the formation of eggs and sperm. An error in cell division called nondisjunction results in a reproductive cell with an abnormal number of chromosomes. For example, an egg or sperm cell may gain an extra copy of chromosome 18. If one of these atypical reproductive cells contributes to the genetic makeup of a child, the child will have an extra chromosome 18 in each of the body’s cells.Mosaic trisomy 18 is also not inherited. It occurs as a random event during cell division early in embryonic development. As a result, some of the body’s cells have the usual two copies of chromosome 18, and other cells have three copies of this chromosome.Partial trisomy 18 can be inherited. An unaffected person can carry a rearrangement of genetic material between chromosome 18 and another chromosome. This rearrangement is called a balanced translocation because there is no extra material from chromosome 18. Although they do not have signs of trisomy 18, people who carry this type of balanced translocation are at an increased risk of having children with the condition.Canavan disease is a type of leukodystrophy and a degenerative disorder that causes progressive damage to nerve cells in the brain. It is inherited in an autosomal recessive manner.Cystic Fibrosis is the most common lethal recessive disease of white people, with a carrier frequency of 1:25 and is inherited in an autosomal recessive manner.Galactosaemic is autosomal recessive and due to mutations in the GALT gene.Phenylketonuria is the most common inborn error of metabolism in the UK with an incidence of 1:10,000 and a carrier rate of 1:50.

Fanconi syndrome is a rare disorder characterized by defective proximal renal tubular reabsorption, which leads to excessive excretion of potassium, phosphate, uric acid, bicarbonates, glucose, and certain amino acids in the urine. Loss of potassium in the urine leads to hypokalaemia, while the loss of phosphate may lead to hypophosphatemic rickets. The overall impact is the failure to thrive and growth retardation.

Adrenal insufficiency is a serious medical condition that leads to inadequate secretion of corticosteroids. The consequences of this deficiency are numerous electrolyte and acid-base imbalances, which include hyponatremia, hyperkalaemia, hypercalcemia, hypoglycaemia, metabolic alkalosis, and dehydration.

Auscultatory findings of VSD vary with the size of the defect. Small VSDs typically produce murmurs ranging from a grade 1 to 2/6 high-pitched, short systolic murmur (due to tiny defects that actually close during late systole) to a grade 3 to 4/6 holosystolic murmur (with or without thrill) at the lower left sternal border; this murmur is usually audible within the first few days of life (see table Heart Murmur Intensity). The precordium is not hyperactive, and the 2nd heart sound (S2) is normally split and has normal intensity.Moderate to large VSDs produce a holosystolic murmur that is present by age 2 to 3 wk; S2 is usually narrowly split with an accentuated pulmonary component. An apical diastolic rumble (due to increased flow through the mitral valve) and findings of heart failure (e.g., tachypnoea, dyspnoea with feeding, failure to thrive, gallop, crackles, hepatomegaly) may be present. In moderate, high-flow VSDs, the murmur is often very loud and accompanied by a thrill (grade 4 or 5 murmur). With large defects allowing equalization of left ventricular and right ventricular pressures, the systolic murmur is often attenuated.

Aniridia is a genetic condition characterized by defects in the formation of a normal iris. The iris may be completely absent or only partially. One of the types of aniridia may be associated with other abnormalities like cataracts, glaucoma, corneal clouding, and nystagmus. The third type of aniridia is associated with intellectual disability, while a fourth type occurs in association with Wilm’s tumour. Aniridia may also be associated with amblyopia and buphthalmos, but macular hypoplasia is not a feature.

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.

One-third of patients with Guillain-Barre syndrome suffer from diaphragm weakness which can lead to further respiratory complications if there is involvement of the tongue, palate, and neck muscles. Forced vital capacity (FVC) is the best way to monitor respiratory muscle function by assessing it repeatedly. Admission for ITU is suggested when FVC is below 20ml/kg and intubation recommended when FVC is 15ml/kg or below. FVC is used in any neurological disorders wherein the respiratory muscles are affected.

Acoustic neuroma/vestibular schwannoma is a benign slow-growing tumour. The clinical picture of the child suggests neurofibromatosis type 1 (NF1), with cafe-au-lait spots and axillary and inguinal freckling.
