Based on the presentation, she probably was administered co-amoxiclav.The liver function tests are highly suggestive of cholestatic jaundice, which is a classic adverse dug reaction related to co-amoxiclav use.Other options:- Erythromycin is more commonly associated with gastrointestinal (GI) disturbance.- Gentamicin is more commonly associated with renal impairment.- Meropenem does not commonly cause cholestasis but is associated with transaminitis.- Vancomycin is associated with red man syndrome on fast administration.

Non Epileptic attack disorder, also known as psychogenic non epileptic seizures, is a condition characterised by episodes of abnormal movement and behaviours that resemble seizures , but are not caused by electrical activity changes in the brain. It is believed that the disorder is caused by the brain’s response to overwhelming or stressful situations. In Jamila’s case, triggering conditions for her episodes may have been the absence of her mother, and the stress of her upcoming examinations. A diagnosis of generalised epilepsy is unlikely because this would require abnormal movement in all 4 limbs during an episode and a longer period of semi consciousness after. Cataplexy can also be ruled out as it does not involve a loss of consciousness which we see in Jamila’s case. Vasovagal syncope does not correspond with the history as there was no evidence of simultaneous collapse and responsiveness coupled with colour change and near spontaneous recovery when supine. A complex partial seizure may be possible in Jamila’s case, however the history of long duration, her eyes being tightly shut and the differences in presentation between the two episodes makes it less likely.

Crossover trials are characterized by the switching of study participants throughout the treatment groups, keeping a random order of switching. This randomization is important to determine any carry-over effect of different treatment modalities. The benefit of this study is the evaluation of the efficacy of various short-term treatment options for the relief of chronic conditions. The washout period is small in this type of study. Crossover studies are more efficient than the parallel studies, but they should be used according to the treatment options and outcomes.

Renal scaring resulting from urinary tract infections can best be determined using Dimercaptosuccinic acid (DMSA) scintigraphy. The scan utilises technetium-99 mixed with the DMSA which is injected into the bloodstream. The radiological dye is taken up by the kidney where it binds to the proximal convoluted tubules. It therefore detects the size, shape and position of the kidney and any scars but is not as useful in assessing dynamic renal excretion. Ultrasound scans are better suited to assess hydronephrosis and dilated ureters. MAG3 scans and MCUG are able to determine the function of kidneys and detect obstructions such as posterior urethral valves and reflux.

Breslow thickness is measured from the top of the granular layer of the epidermis (or, if the surface is ulcerated, from the base of the ulcer) to the deepest invasive cell across the broad base of the tumour (dermal/subcutaneous) as described by Breslow.Margins of excision-Related to Breslow thicknessLesions 0-1mm thick – 1cmLesions 1-2mm thick – 1- 2cm (Depending upon site and pathological features)Lesions 2-4mm thick – 2-3 cm (Depending upon site and pathological features)Lesions >4 mm thick – 3cmMarsden J et al Revised UK guidelines for management of Melanoma.

The initial symptoms of spasmodic abdominal pain, rectal bleeding and vomiting might point towards intussusception, but the peak incidence is in children aged 6-9 months. Considering that this child has additional symptoms of haematuria, proteinuria and a purpuric rash, it is more likely that the child has Henoch-Schonlein purpura (HSP). HSP is an identifiable cause of intussusception. It is an IgA-mediated, autoimmune hypersensitivity vasculitis that targets the small vessels of the skin, GI tract, kidneys, and joints. It is most commonly seen in children aged 3 – 6years and is twice as common in boys than girls. Preceding viral URTI with low-grade pyrexia is common. The most common organism associated with HSP is, however, Group A streptococcal infection. A purpuric rash is seen on the back of the legs and buttocks and can less frequently, affect the arms. Arthralgia is common (usually knees/ankles) in these patients. Abdominal pain and bloody diarrhoea may occur. And half of the children with HSP have renal involvement. Rarely, it can lead to end-stage renal failure. Treatment includes adequate hydration, occasionally steroids, and other immunosuppressants. The disease can recur in 1 in 3 children.

Because of the patient’s history of chronic analgesic use of daily paracetamol intake, the most likely diagnosis of this case is Analgesic misuse headache. In these cases, the headache is only temporarily relieved by analgesics. Treatment involves gradual withdrawal of analgesics.

In haemophilia C, The severity of the deficiency is based on plasma factor XIC (clotting) activity. Major factor XI deficiency is present when the activity of factor XI in plasma is less than 1-15 IU/dL.In major deficiency factor XI, bleeding is related to injury, especially when trauma involves tissues rich in fibrinolytic activators, such as the oral mucosa, the nose, and the urinary tract. Unlike patients with severe haemophilia A or B, patients with major factor XI deficiency do not spontaneously bleed.The aPTT is usually prolonged in factor XI deficiency (but depends on the sensitivity of the reagent and test system–partial deficiency can be missed), whereas the PT and TT are normal.

Gitelman syndrome is a kidney disorder that causes an imbalance of charged atoms (ions) in the body, including ions of potassium, magnesium, and calcium.The signs and symptoms of Gitelman syndrome usually appear in late childhood or adolescence. Common features of this condition include painful muscle spasms (tetany), muscle weakness or cramping, dizziness, and salt craving. Also common is a tingling or prickly sensation in the skin (paraesthesia), most often affecting the face. Some individuals with Gitelman syndrome experience excessive tiredness (fatigue), low blood pressure, and a painful joint condition called chondrocalcinosis. Studies suggest that Gitelman syndrome may also increase the risk of a potentially dangerous abnormal heart rhythm called ventricular arrhythmia.

This clinical presentation is highly suggestive of choking. According to the BLS algorithm, the next step in managing a case of choking in a conscious child with an ineffective cough is five back blows.Other options:- Adrenaline intramuscularly: The history is similar to anaphylaxis, but the absence of a rash or oedema and the acute onset make choking more likely in this situation. Thus, adrenaline will not be of use in this patient.- CPR at a ratio of 15:2: Since the child is conscious, it is not advised. If the child were unconscious, you would commence basic life support.- Five abdominal thrusts: In the given scenario, the child is an infant. Abdominal thrusts are avoided in infants due to the risk of intra-abdominal injury.

Adenoid tissue sometimes swell as a result of fighting off the infection as germs are trapped in the adenoids. Adenoid enlargement is suspected.

Presentation can vary by individual. Early stages are often characterized by malaise, fatigue, and lethargy. One to 3 months of inadequate intake can lead to anaemia, myalgia, bone pain, easy bruising (Figure 3), swelling, petechiae, perifollicular haemorrhages, corkscrew hairs, gum disease, poor wound healing, mood changes, and depression. Perifollicular haemorrhages and easy bruising are often first seen in the lower extremities, as capillary fragility leads to an inability to withstand hydrostatic pressure. Late stages of scurvy are more severe and life threatening; common manifestations include generalized oedema, severe jaundice, haemolysis, acute spontaneous bleeding, neuropathy, fever, convulsions, and death.

Ehlers-Danlos Syndrome (EDS) is a group of genetic connective tissue disorders with over 13 clinical subtypes. Hyper-mobility is common to many of these subtypes. Vascular EDS is identified by thin, translucent skin prone to easy bleeding, as well as the risk of early arterial rupture, gastrointestinal perforation and uterine rupture. Those affected have dysmorphic features including a thin nose and lips, sunken cheeks and large eyes. The other features including; atrophic scars, a dominant family history, hyper extensible skin and kyphoscoliosis are not specific to vascular EDS and overlap in many of the subtypes.

Adrenal insufficiency is a serious medical condition that leads to inadequate secretion of corticosteroids. There are three main types of adrenal insufficiency: primary, secondary, and tertiary, based on the location of the abnormality. Primary adrenal insufficiency is caused by any pathology located inside the adrenal glands. The most common cause of primary adrenal insufficiency is Addison’s disease, which is an autoimmune condition. Adrenoleukodystrophy is an X-linked neurodegenerative disease that also causes primary adrenal insufficiency. Secondary adrenal insufficiency is caused by any pathological impairment of the pituitary gland or the hypothalamus. The important causes of secondary adrenal insufficiency include iatrogenic (steroid use), pituitary tumours like craniopharyngioma, and conditions leading to panhypopituitarism like Sheehan’s syndrome. Tertiary adrenal insufficiency is caused by the deficiency of the corticotropin-releasing hormone. Hypoparathyroidism does not cause adrenal insufficiency.

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.

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

Based on the clinical scenario provided, this patient most probably has impacted gall stones. Gall stones in children can be caused by haematological diseases such as sickle cell anaemia and thalassemia. Cholesterol stones are also becoming more prevalent. A dilated common bile duct (> 10mm in adults) suggests gall stone impaction. The presence of pyrexia indicates cholecystitis.

The most probable diagnosis for this patient would be external angular dermoid.External angular dermoids typically form where there are overlapping tissue planes such as the midline. They contain a caseous material. The cysts are essentially benign in nature and are excised for cosmetic purposes or when they encroach on vision.Other options:- Branchial remnant typically presents as a supraclavicular pit.- Sebaceous cysts tend to be present on the scalp.- There is nothing in the clinical scenario to suggest a vascular malformation such as pigment change or ‘bag of worms’.- Lymphatic malformations are typically found in the neck or under the axilla.

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

Answer: The burn area is extremely painful until skin graftedThird-degree burns destroy the epidermis and dermis. Third-degree burns may also damage the underlying bones, muscles, and tendons. The burn site appears white or charred. There is no sensation in the area since the nerve endings are destroyed. These are not normally painful until after skin grafting is done since the nerve endings have been destroyed.

Bernard- Soulier Syndrome results from a deficiency of platelet glycoprotein protein Ib, which mediates the initial interaction of platelets with the subendothelial components via the von Willebrand protein. It is a rare but severe bleeding disorder. Platelets do not aggregate to ristocetin. The platelet count is low, but, characteristically, the platelets are large, often the size of red blood cells, and may be missed on complete blood counts because most automatic counters do not count them as platelets.

Pellagra occurs as a result of niacin (vitamin B-3) deficiency. Niacin is required for most cellular processes. Since tryptophan in the diet can be converted to niacin in the body, both of these need to be deficient for pellagra to develop.The classical triad of symptoms is diarrhoea, dermatitis and dementia.The first sign is reddened skin with superficial scaling in areas exposed to sunlight, heat and friction. This may resemble severe sunburn then gradually subsides leaving a dusky brown-red colouration. The rash is usually symmetrical with a clear edge between affected and unaffected skin.

CUTANEOUS DISORDERS OR DERMATOSIS ASSOCIATED WITH IBD- Psoriasis- Secondary amyloidosis- Vitiligo- Acquired epidermolysis bullosaIn some cases, non-granulomatous skin disorders occur as a reaction to the intestinal disease. These include:- Pyoderma gangrenosum- Neutrophilic dermatosis / Sweet syndrome, typically with pustules- Pyodermatitis-pyostomatitis vegetans, a purulent erosive dermatosis characterised by snail-track ulcers- Erythema multiforme- Erythema nodosum- Acneiform eruptions including nodulocystic acne, hidradenitis suppurativa and folliculitis- Palisaded neutrophilic and granulomatous dermatitis- Necrotizing and granulomatous small vessel vasculitis.

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.

Topical benzoyl peroxide is used for the treatment of mild to moderate acne vulgaris. It is actually a peeling agent and it clears the pores and reduces the bacterial cell count.

The most probable diagnosis for this patient is bilateral retractile testes. This a normal phenomenon in some pre-pubertal boys. Rationale:Testicular descent can continue until about 3-months of age. The pre-pubertal testis is small enough that with activation of the cremasteric reflex, they can enter the inguinal canal. This in itself is a normal finding providing the testis can be brought into the scrotum without tension and does not require surgical correction. With time the testis will lie within the scrotum. Orchidopexy for true undescended testis can be performed from 6-months of age. It is also warranted if the testes remain undescended or intra-abdominally leading to infertility.Other options:- An ascending testis is one, typically, following hernia or orchidopexy surgery that was in the testis but with time is within the inguinal canal and cannot be brought into the scrotum. Orchidopexy is required for this.- No surgery is required as when the testis enlarges with puberty it will remain within the scrotum.- The testes can be brought into the scrotum. Therefore they are not undescended.- The testes are retractile not ascending; ascending testis cannot be brought into the scrotum and would require orchidopexy.

Mongolian spots are, hyper-pigmented, non-blanching patches present on the back and gluteal region at birth. They are commonly found in African and Asian ethnic groups, and can also present in infants of Mediterranean and middle eastern descent. Though the spots usually disappear by puberty, some may persist into adulthood.

Neurofibromatosis is a genetic disease caused by the mutation of the neurofibromin gene on Chromosome 17. The diagnostic criteria for Neurofibromatosis type 1 are two or more of the following:-6 or more cafe au lait macules-2 or more cutaneous neurofibroma or one plexiform Neurofibroma-Axillary of groin freckling -Optic pathway glioma -2 or more Lisch nodules (hamartomas of the iris seen on slit lamp examination)-Bony dysplasia (such as sphenoid wing dysplasia, bowing of the long bones, or pseudarthrosis)-First degree relative with neurofibromatosis type 1

Effective treatment can cure gonorrhoea and help prevent long-term complications. CDC recommends a single dose of 250mg of intramuscular ceftriaxone AND 1g of oral azithromycin. It is important to take all of the medication prescribed to cure gonorrhoea.
