  8. Regarding seborrhoeic dermatitis in infants, which TWO of the following statements are correct? Select TWO answers only.a. It usually affects the flexures of the elbow and at the back of the knees.b. It usually disappears by three months.c. If medical treatment is required, ketoconazole 2% cream is a suitable treatment.d. A rare complication requiring urgent admission is Leiner's disease. The correct answers are C and D.In infants, seborrhoeic dermatitis usually affects the scalp (hence it is sometimes called 'cradle cap'). It can affect the face and body. It usually clears spontaneously within a few weeks or months (most cases clear by six to 12 months of age). If medical treatment is required, 2% ketoconazole cream or shampoo can be effective. Leiner's disease is a rare complication requiring urgent admission. It presents with a sudden confluence of lesions leading to universal scaling redness of the skin. The infant is severely ill with anaemia, diarrhoea, and vomiting.

  9. Regarding childhood febrile convulsions, which ONE of the following statements are correct? Select ONE answer only. a. The incidence is 2% to 4%. b. The peak incidence is at 12 months. c. Usually focal seizures are observed. d. Seizures usually last 20+ minutes.

Usually focal seizures are observed. d. Seizures usually last 20+ minutes. The correct answer is A. A childhood febrile convulsion is a seizure occurring in a child aged six months to five years, associated with fever arising from infection or inflammation outside the central nervous system in a child who is otherwise neurologically normal. The peak incidence is at 18 months, and seizures are usually focal and last three to six minutes.

  11. Regarding febrile convulsions in children, which THREE of the following are the MOST common causes of the fever? Select THREE answers only. a. Urinary tract infection (UTI) b. Post immunisation fever c. Viral infection d. Otitis media e. Lower respiratory tract infection (LRTI) f. Meningitis

Methicillin resistant S. aueus (MRSA) c. Escherichia coli d. Candida albicans e. Pseudomonas f. Streptococcus g. Proteus The correct answer is D. Nappy rash is a dermatitis confined to the area covered by the nappy. It is not one distinct diagnosis, but a multifactorial problem with many possible causative factors including infrequent nappy changes, contact with faeces or urine, use of broad spectrum antibiotics and chemical irritants. Candida albicans is the most important causative microorganism.

  18. Regarding acute angle closure glaucoma, which TWO of the following statements are correct? Select TWO answers only. a. Patients present more commonly in the winter, and symptoms often present in the evening. b. Pupils become constricted, with a pin prick appearance. c. The eye is typically red and very painful. d. Patients should be referred to an ophthalmologist for an outpatient appointment within two weeks of presentation. e. The eye is typically red and painless. The correct answers are A and C. Acute angle-closure glaucoma is a rapid and severe rise in intra ocular pressure caused by physical obstruction of the anterior chamber drainage angle. It often presents in the evening when reduced light causes mydriasis (thus it is more common in the winter), and presents with a red, painful eye. It requires URGENT admission (same day) as delay can cause blindness.

  19. Regarding acute angle closure glaucoma, which THREE of the following are risk factors? Select THREE answers only. a) Hypermetropia b) Myopia c) Amblyopia d) Caucasian descent e) Asian descent f) Afro-Caribbean descent g) Previous attack in the other eye

Select THREE answers only. a) Hypermetropia b) Myopia c) Amblyopia d) Caucasian descent e) Asian descent f) Afro-Caribbean descent g) Previous attack in the other eye The correct answers are A, E and G. Acute angle closure glaucoma is rare, affecting 1 in 1,000 people over the age of 40. Other risk factors include increasing age, having shallow anterior chambers, and family history.

  21. Regarding the following infectious organisms... a. Staphylococcus aureus b. Chlamydia trachomatis c. Trichomonasvaginalis d. Candida albicans e. Pseudomonas f. Streptococcus pneumonie g. Proteus species h. Dermatophytes i. Enterobiusvermicularis For each of the following presentations, which is the MOST likely causative organism? You may use each option ONCE, MORE than ONCE, or not at all. A four year-old girl presents with intense perianal itching. This is much worse at night, and has caused poor sleep and uncharacteristic irritability. The symptoms have been present for two weeks. Her older sister (aged six) has had similar symptoms.

  22. The correct answer is I. Enterobius vermicularis (threadworm) is the most common helminth infection in the UK. It can be asymptomatic, or present with intense perianal itching worse at night (when the eggs are laid). Adult threadworms live for upto six weeks.

She was last seen in the surgery a week before and treated for an acute sinusitis. She is not sexually active.

  24. The correct answer is D. These symptoms are common in vulvovaginal candidiasis. The most common causative agent is Candida albicans. It is often precipitated by another illness, or by the use of broad spectrum antibiotics. Chlamydia can also present with vaginal discharge and dysuria, but rarely causes itch.

  25. Regarding the following infectious organisms... a. Staphylococcus aureus b. Chlamydia trachomatis c. Trichomonas vaginalis d. Candida albicans e. Pseudomonas f. Streptococcus pneumonie g. Proteus species h. Dermatophytes i. Enterobius vermicularis For each of the following presentations, which is the MOST likely causative organism? You may use each option ONCE, MORE than ONCE, or not at all. A 20 year-old woman presents with vulval itching, dysuria and an offensive discharge. On examination there is a frothy yellow-green discharge. Her only regular medication is the oral contraceptive pill (OCP).

  26. The correct answer is C. Trichomonas vaginalis is a flagellated protozoan which is usually transmitted sexually. Upto 50% of infected women may be asymptomatic. Symptoms include vulval itch, dysuria and a coloured, offensive discharge.

  27. Regarding the known side effects of the following drugs... a. Simvastatin b. Ramipril c. Prednisolone d. Celecoxib e. Methotrexate f. Isotretinoin g. Dermovate h. Minocycline i.

  36. The correct answer is A: <140/85. The maximum acceptable level according to the guidelines (the audit standard) is 150/90. This is the target adopted for gaining QOF points in the new GMS contract. For diabetics, the target is much lower: 130/80.

  37. Which ONE of the following drugs is associated with the highest increased risk of suicide in adolescents AND adults? a. Fluoxetine b. Citalopram c. Venlafaxine d. Paroxetine e. Duloxetine

  38. The correct answer is D: Paroxetine. A recent report confirmed that there is a significantly increased risk of suicide in adults taking Paroxetine compared to placebo. There have already been many reports about an increased risk in adolescents.

  39. Regarding statistics in screening, which TWO of the following statements are correct? Choose TWO answers only. a. The sensitivity is the same as the false positive rate. b. The specificity is the same as the false negative rate. c. The specificity is the same as the true negative rate. d. The sensitivity is the same as the true negative rate. e. The predictive value negative is the probability that a person does not have the disease given a negative test.

  40. The correct answers are C and E. Sensitivity is the probability that the screening test is positive given that the person actually has the disease. It is the same as the true positive rate. The specificity is the probability that the screening test is negative given that the person does NOT have the disease. It is the same as the true negative rate. The ideal screening tool would be 100% sensitive and 100% specific.

  44. Regarding 'frozen shoulder', which THREE of the following are correct? Choose THREE answers only. a. Diagnosis requires abnormal clinical and x-ray findings. b. It is characterized by insidious shoulder stiffness; severe pain, even at night; and severe loss of passive and active external rotation of the shoulder. c. It is common in athletes aged 20 to 30. d. Steroid injections offer no benefit over physiotherapy. e. Difficult cases may need arthroscopic release. f. It is associated with diabetes mellitus. The correct answers are B, E, and F. Frozen shoulder is a clinical diagnosis. It is characterised by insidious shoulder stiffness; severe pain, even at night; and severe loss of passive and active external rotation of the shoulder. X-ray is often normal or may show periarticular osteopenia as a result of disuse. It is rare in patients under 40, and slightly more common in women than men. Physiotherapy alone is of little benefit, although it is useful in combination with steroid injection of the joint (which is the mainstay of treatment).
