Case-based MCQ | #Case_351 | #answer 〰〰〰〰〰〰〰〰〰〰〰〰〰〰 ✅ D In statistics and epidemiology, relative risk or risk ratio (RR) is the ratio of the probability of an event occurring in an exposed group to the probability of the event occurring in a non-exposed, comparison group. Of 100 diabetic smokers who are on aspirin, 1 person has developed a coronary event. So the incidence of coronary event in this group is 1 % [1 /(1+99)x100], while the incidence of coronary events in the group taking placebo instead of aspirin is 2% [2/(2+98)x100]. In this scenario the exposure is taking aspirin. Exposed group has a 1 % chance of developing a coronary event versus 2% in those who do not take aspirin. The RR is then calculated by dividing the odds of the condition in the exposed group (1 % ) by that of the non-exposed group: RR = P(exposed) / P(non-exposed) : RR =1 % / 2% =0.5 Here, the RR indicates that the odds of developing a coronary event in those diabetic smokers who are on aspirin is half compared to those on placebo. In other words, those who are on aspirin has a 50% risk reduction. Inversely, those who are not taking aspirin are twice as likely to develop a coronary event compared to those who are taking it. So the RR. This means that not taking aspirin is associated with a 200% increase in incidence of coronary events.

Case-based MCQ | #Case_350 | #answer 〰〰〰〰〰〰〰〰〰〰〰〰〰〰 ✅ C The fleshy red lesion on the distal intephalageal joint of this patient is consistent with the diagnosis of pyogenic granuloma (PG). PG is a common benign, acquired vascular neoplasm of the skin and mucous membrane. The etiology is unknown. Some think it might be due to minor trauma especially for PGs of fingers. Pyogenic granuloma is a misnomer because the lesion is neither pyogenic, nor a granuloma ! It is an erythematosus (fleshy red), dome-shaped papule or nodule that bleeds easily, and is prone to ulceration, erosion and crusting. It is most often seen in adolescents and young adults. Up to 5% of pregnant women may experience it. Although very rare, PGs have been reported in the gastrointestinal tract, the larynx, nasal mucosa, conjunctiva and cornea. ⚠ (Options A, D and E) Abscess, epidermoid cyst, and mucous cyst are covered with skin. ⚠ (Option B) Pyoderma gangrenosum typically presents with a well-defined border, which is usually violet or blue.

🧩 Medical Mnemonics Enzyme inducers and contraceptive pill A disrespectful but good #mnemonic to remember for enzyme inducers is: CRAP GPs 🙈💩 ✍ Whilst majority of GPs are absolutely fantastic, if a GP prescribes rifampicin and combined oral contraceptive pill without informing the woman of contraception failure, he may be called a Crap GP. A good GP would discuss the use of additional barrier methods, having progesterone only injections, insertion of intrauterine devices or use of increasing dose of oestrogen.Carbamazepine ⛔ Rifampicin ⛔ Alcohol – chronic consumption ⛔ Phenytoin ⛔ Griseofulvin ⛔ Phenobarbital ⛔ sulfonylureas #obs_and_gyneacology 〰〰〰〰〰〰〰〰〰〰〰 ©Medical Mnemonics

Case-based MCQ | #Case_349 | #answer 〰〰〰〰〰〰〰〰〰〰〰〰〰〰 ✅ E Lichen sclerosus is a chronic inflammatory dermatosis which usually affects the skin of the anogenital region in women. It presents with general itching and is seen as white atrophic plaques. It occurs in little girls or middle-aged women. It is thought to have an autoimmune mechanism in the pathogenesis. The main complaint is itching which is worse at night. Dyspareunia and pain may be seen in cases of erosions or fissures. Topical steroids are used as part of the management. Follow-up is important and is recommended at three and six months, to ensure respoonse to treatment. This is because long standing, untreated cases show a 4% incidence of malignant change (association with development of squamous cell carcinoma of the vulva).

Case-based MCQ | #Case_348 | #answer 〰〰〰〰〰〰〰〰〰〰〰〰〰〰 ✅ A Note that the patches of the skull are sclerotic and not lytic. Sclerotic patches represent Paget’s disease (osteitis deformans) whereas if it was lytic lesions on the skull it would represent multiple myeloma. Alkaline phosphatase is seen to be raised in both Paget’s disease and multiple myeloma however it is usually seen raised in multiple myeloma only when associated with fractures. Note that there are two types of Paget’s disease: 1. Paget’s disease of the bone (osteitis deformans) 2. Paget’s disease of the breast

Case-based MCQ | #Case_347 | #answer 〰〰〰〰〰〰〰〰〰〰〰〰〰〰 ✅ C The abdominal x-ray shows evidence of mucosal oedema and thumb-printing typical of ischaemic colitis. Given the history of arterial disease (cardiac and peripheral) it is likely that the pathology is a chronic progressive atherosclerotic lesion at the origin of the superior mesenteric artery. The patient requires investigation to confirm the diagnosis and management may require revascularisation of the ischaemic bowel.
