Combined oral contraceptives have been shown to increase the chances of pulmonary embolism leading to right heart strain and failure. Other causes for raised JVP with normal waveform being fluid overload and bradycardia.


319. (D)
Cannon waves (large a wave with rapid fall) are caused due to atrial systole against a closed ventricular valve. Other causes being complete heart block, single ventricular pacing, atrial flutter, single chamber ventricular pacing, nodal rhythm and ventricular extrasystole.


320. (B)
Smoking predisposes to SVC obstruction.




321. (H)

413. A 25-year-old pregnant HIV positive woman concerned about minimizing the risk of transmission of HIV to her fetus.



Answers: Prophylactic Treatment

409. (C)
For biliary surgery ampicillin 500-mg iv/8-hr for 3 doses or cefuroxime 750 mg/ 8h for 3 doses iv / im.


410. (K)
Clindamycin 600-mg 1-hour before local anesthetic procedure. If can tolerate penicillin, amoxicillin 3 gram 1 hour before procedure.


411. (H)
Rifampin is indicated in the treatment of closed contacts of patients with proved or suspected infection caused by Neisseria meningitides. These contacts include other household members, children in nurseries, persons in day care centers, and closed populations, such as military recruits. Health care providers who have intimate exposure (e.g. mouth-to-mouth resuscitations) with index cases also should receive prophylactic therapy. Household members and other close contacts of patients with recently diagnosed tuberculosis who have a positive tuberculin skin test (PPD) of 5-mm, [tuberculin-negative children and adolescents who have been close contacts of infections person within the past 3 months are also candidates for preventative therapy until a repeat PPD is done 12 weeks after contact with the infectious source].

412. (F)
Chloroquine crosses the placenta. Use is not recommended during pregnancy except in the suppression or treatment of malaria or hepatic amebiasis since malaria poses greater potential danger to the mother and fetus (ie. abortion and death) than prophylactic administration of chloroquine. Chloroquine, given in weekly chemoprophylactic doses, has not been shown to cause adverse effects on the fetus.

413. (G)
Zidovudine is indicated for the prevention of maternal-Foetal HIV transmission as part of a regiment that includes oral zidovudine beginning between 14 and 34 weeks gestation, continuous intravenous infusion of zidovudine during labor, and administration of zidovudine syrup to the neonate for the first six weeks of life. However, transmission to infect may still occur in some cases despite the use of this regimen.

Answers: Diagnosis of Pruritus

421. (J)
Lichen planus (LP) is a papulosquamous disorder in which the primary lesions are pruritic, polygonal, flat-topped, violaceous papules. Close examination of the surface of these papules will often reveal a network of gray lines (Wickham’s striae). The skin lesions may occur anywhere, but they have a predilection for the wrists, shins, lower back, and genitalia. Involvement of the scalp may lead to hair loss. LP commonly involves mucous membranes, particularly the buccal mucosa, where it can present as a white netlike eruption. Its etiology is unknown.

422. (I)
Transfer of newly fertilized female mites from person to person occurs by intimate personal contact and is facilitated by crowding, uncleanliness, and sexual promiscuity. Medical practitioners are at particular risk of infestation. Outbreaks occur in nursing homes, mental institutions, and hospitals. Patients with scabies report intense itching that worsens at night and after a hot shower. Typical burrows may be difficult to find because they are few in numbers and may be obscured by excoriations. The possibility of other sexually transmitted diseases should be excluded in adults with scabies. Sites include finger webs, wrists, elbows, ankles, genitalia and breasts. Treat with Malathion or permethrin.

423. (D)
Urticaria (hives) are transient lesions that are composed of a central wheal surrounded by an erythematous halo. Individual lesions are round, oval or figurate, and they are often pruritic. Acute and chronic urticaria has a wide variety of allergic etiologies.

424. (A)
Antimitochondrial antibody (AMA) is detected in more than 90 percent of patients with primary biliary cirrhosis amount patients with symptomatic disease, 90 percent are women aged 35 to 60. Often the earliest symptom is pruritus, which may be either generalized or limited initially to the palms and soles. In addition, fatigue is commonly a prominent early symptom. After several months or years, jaundice and gradual darkening of the exposed areas of the skin (melanosis) may ensue.

425. (K)
Uremic symptoms include fatigue, breathlessness, ankle swelling, anorexia, vomiting, nocturia and pruritus. Examination can reveal pigmentation, pallor and brown nails.


Theme: Diagnosis of sore throat

Options
A. Acute otitis media
B. HIV
C. Infectious mononucleosis
D. Diphtheria
E. Agranulocytosis
F. Scarlet fever
G. Acute follicular tonsillitis
H. Pharyngitis

Instructions: Match each clinical scenario below with the MOST appropriate diagnosis from the list of the options above. Each option may be used once, more than once and not at all.

426. A 30-year-old woman presents to her GP with score throat. She is being treated for thyrotoxicosis currently.
427.A 7-year-old child is presented to his GP with sore throat, a punctate erythematous rash and circumoral pallor.
428. A 4-year-old child complain of sore throat and earache. He is pyrexial. On examination tonsils enlarged and hyperemic exude pus when pressed upon.
429. A 30-year-old man presents in A&E department with difficulty in breathing. He has returned from India recently. Examination of his throat revealed grey membranes on the tonsils and uvula. Pyrexia is mild.
430. A 23-year-old man presents with severe malaise and sore throat. He has red tonsils with yellow membranes and cervical lymphadenopathy.



Answers: Diagnosis of Sore Throat

426. (E)
Agranulocytosis is a recognized side effect of carbimazole, used for the treatment of thyrotoxicosis. Patients receiving this drug should be warned, therefore, to see their GP if sore throat/mouth ulcers/fever develops.


427. (F)
It is difficult to make a mistake dealing with such a bright clinical picture. In addition these patients have a characteristic tongue, which is described as ‘strawberry and cream’.


428. (G)
The child has typical follicular tonsillitis. The pus exuding from the crypts is characteristic. Earache in that case is usually referred.


429. (D)
Diphtheria has become rare in the UK but it is emerging again in some parts of eastern Europe and south east Asia. Hence, recent travel to these continents is characteristic. Diphtheria presents sometimes as an emergency when severe oedema and membranes lead to airway obstruction and as phyxia. Firmly attached grey membranes that are difficult to remove and that leave a bleeding surface after an attempt to peel them off point towards the diagnosis.

430. (C)
The clues to the diagnosis in this young man are malaise, which is often more severe than in acute tonsillitis, yellow membranes on the tonsils and enlarged lymph nodes. Diagnosis is confirmed by lymphocytosis in the peripheral blood and positive Paul-Bunnel test.

431. (F)
Fludrocortisone is used in conjunction with increased sodium intake in the treatment of idiopathic orthostatic hypotension.


432. (I)
This patient has bacterial overgrowth as illustrated by the positive hydrogen breath test. The most suitable antibiotic to reduce overgrowth would be tetracycline.


433. (G)
Metoclopramide is indicated for the relief of symptoms of acute and recurrent diabetic gastroparesis. Previously, cisapride was a particularly good treatment although this has been withdrawn due to the prolongation of the QT-interval.

For each question below, choose the SINGLE most likely answer form the above list of options. Each option may be used once, more than once, or not at all.

442. A 75-year-old woman presents with history of several falls over the past 5 months. She says that they come on suddenly without warning and reports no loss of consciousness.
443. A 70-year-old woman brought by her daughter with a history of being off legs. Her balance has been poor for some time and she walks with a stamping gait. Romberg’s test is positive.
444. A 65-year-old man presents with history of several falls over the past one year. He finds it increasingly difficult to dress by himself and carry out activities of daily living. Examination revealed a tremor in the upper limb with hypotonia. He could not stand erect even with his eyes open.
445. A 60-year-old lady complains of giddiness and vomiting since the last 3 days. Her symptoms are exacerbated by head movements and she cannot stand without support.
446. A 58-year-old woman presents with recurrent falls associated with giddiness, particularly on getting up in the mornings. She has underlying ischaemic heart disease and is on aspirin, an oral nitrate and a beta-blocker.



Answers: Diagnosis of falls

442. (L)
Drop attacks resulting from impaired blood supply to the motor pathways of the brainstem cause sudden paraparesis or quadriparesis, usually lasting only a few seconds. Sudden drop attacks may mimic syncope. Isolated loss of consciousness is rare.

443. (I)
Imbalance with sensory ataxia is characterized by marked worsening when visual feedback is removed. The patient can often assume the upright stance with feet together cautiously with eyes open. With eye closure, balance is rapidly lost (positive Romberg’s signs) in various directions at random. Sensory examination reveals impairment of proprioception at the toes and ankles, usually associated with an even more prominent abnormality of vibratory perception. Prompt evaluation for vitamin B12 deficiency is important, as this disorder is reversible if recognized early. Depression or absence of reflexes points to peripheral nerve disorders. Spasticity with extensor plantar responses suggest posterior column and spinal cord disorders.

444. (J)
Once a desired position is reached, imbalance may be surprisingly mild. As walking begins, the imbalance recurs. Patients usually learn to lessen the imbalance by walking with the legs widely separated. Clinical signs of cerebellar limb ataxia include dysmetria, intention tremor, dysdiadochokinesia, and abnormal rebound. Muscle tone is often modestly reduced; this contributes to the abnormal rebound due to decreased activation of segmental spinal cord reflexes and also to pendular reflexes, i.e, a tendency for a tendon reflex to produce multiple swings to and fro after a single tap.

445. (E)
Imbalance with vestibular dysfunction is characterized by a consistent tendency to fall to one side. The patient commonly complains of vertigo rather than imbalance, especially if the onset is acute. Acute vertigo associated with lateralized imbalance but no other neurologic signs is often due to disorders of the semicircular canal.


446. (B)
Hypotension is a side-effect of most anti-anginal medications.

456. A 65-year-old woman complains of urinary frequency and urgency. She does not like taking tablets. Examination is normal.


Answers: Treatment of urinary incontinence

452. (E)
The history is suggestive of acute cord compression, which can cause overflow incontinence, MRI is the investigation of choice. Radiotherapy is usually the treatment of choice, especially when metastatic disease is present. For localized cord compression from a newly diagnosed tumour or tumours with poor response to radiotherapy e.g. adenocarcinoma of lung or bowel, decompression surgery is alternative.


453. (G)
Post-natal pelvic floor muscle exercises are useful in preventing stress inconti-nence. The right movement is when urine is stopped mid-stream.


454. (C)
The classical presentation of normal pressure hydrocephalus is dementia, gait disturbance (pathognomonic ‘glued-to-the-floor’ sing) and incontinence. CT head shows disproportionate ventricular englargement compared with degree of cortical atrophy. Ventricular shunting is the definitive treatment.


455. (H)
Failure to fill and empty (uncoupling of detrusor and internal sphincter function) occurs with detrusor contractions against a closed sphincter. There will be overflow incontinence for which intermittent self-catheterization is the treatment of choice. Anticholinergics can be tried if urgency/frequency present.


456. (J)
Bladder retraining exercises is useful in urge incontinence. Increase intervals of regular toileting from initial 30 minutes, increasing by 10-15 minutes every few days until intervals of 2-4 hours reached. Anticholinergics are also used to control detrusor instability.

Answers: Diagnosis of Lesions around the Eye

484. (F)
Basal cell CA
There are several clinical types of BCC. The most common is noduloulcerative BCC, which begins as a small, pearly nodule, often with small telangiectatic vessels on its surface. The nodule grows slowly and may undergo central ulceration. Various amounts of melanin may be present in the tumour; tumors with a heavier accumulation are referred to as pigmented BCC. Superficial BCC consists of one or several erythematous, scaling plaques that slowly enlarge.

485. (I)
Chalazion (hordeolum internum)
A chalazion is a painless, granulomatous inflammation of a meibomian gland that produces a peal like nodule within the eyelid. It can be incised and drained, or injected with glucocorticoids.

486. (H)
Stye (hordeolum externum)
An external hordeolum (sty) is caused by staphylococcal infection of the superficial accessory glands of Zeis or Moll located in the eyelid margins.

487. (B)
Dacryoadenitis



488. (J)
Xanthelasma
Yellow-colored cutaneous papules or plaques, xanthelasma are found on the eyelids, whereas tendon xanthomas are frequently associated with the achillis and extensor finger tendons; The least specific sign for hyperlipidemia is xanthelasma because at least 50 percent of the patients with this finding have normal lipid profiles.

489. (D)
Molluscum contagiosum
A benign disease characterized by pearly, flesh-colored, umbilicated skin lesions 2 to 5 mm in diameter. The infection can be transmitted by closed contact, including sexual intercourse. Lesions typically occur in the genital region but can be found anywhere on the body except the palms and the soles. In most cases the disease is self-limited and has no systemic complications. Develops especially often in association with the advanced stages of HIV infection.

490. (I) The triad of arthritis, urethritis, and conjunctivitis, became known as Reiter’s syndrome, often occurring with additional mucocutaneous lesions. A similar spectrum of clinical manifestations can be triggered by enteric infection with any of several Shigella, Salmonella, Yersinia, & Campylobacter species, by genital infection with Chlamydia trachomatis. Since most patients with spondyloarthropathy do not have the classic features of Reiter’s syndrome, it has become customary to employ the terms reactive arthritis. Constitutional symptoms are common, including fatigue, malaise, fever, & weight loss. The musculoskeletal symptoms are usually acute in onset. Arthritis is usually asymmetric & additive. The joints of the lower extremities, especially the knee, ankle, & subtalar, metatarsophalangeal, & toe interphalangeal joints, are the most common sites of involvement, tendinitis & fascitis are particularly characteristic lesions. Urogenital lesions may occur throughout the course of the disease. In males, urethritis may be marked or relatively asymptomatic. Prostatitis is also common. Similarly, in females, cervicitis or salpingitis may be caused. Ocular disease is common, ranging from transient, asymptomatic conjunctivitis to an aggressive anterior uveitis. Mucocutaneous lesions are frequent. Oral ulcers tend to be superficial, transient, & often asymptomatic. The characteristic skin, lesions, keratoderma blenorrhagica, consist of vesicles that become hyperkeratotic, ultimately forming a crust before disappearing. They are most common on the palms & soles but may occur elsewhere.
491. (A) The symptoms of the disease are usually first noticed in late adolescence or early adulthood consisting of low-back morning stiffness which becomes per sistent within months. Arthritis in the hips & shoulders (“root” joints) occurs in 25 to 35 percent of patients, in many cases early in the disease course. The most common extraarticular manifestation is acute anterior uveitis, which can antedate the spondylitis. Aortic insufficiency, sometimes producing symptoms of congestive heart failure, occurs in a few percent of patients, occasionally early in the course of the spinal disease. Up to half the patients have inflammation in the colon or ileum. This is usually asymptomatic, but in 5 to 10 percent of patients with AS, frank IBD will develop. The HLA-B27 gene is present in approximately 90 percent of patients with AS. X-ray shows “squaring” of the vertebral bodies. Exercise increases mobility & improves function. Most patients require anti-inflammatory agents to achieve sufficient symptomatic relief to be able to remain functional & carry out the exercise program.
492. (K) Ninety percent of patients present with involvement of a single joint: most commonly the knee. The usual presentation consists of moderate to severe pain that is uniform around the joint, effusion, muscle spasm, & decreased range of motion. Fever in the range of 38.3 to 38.90C (101 to 1020F). A focus of extraarticular infection, such as a boil or pneumonia, should be sought. Peripheral-blood leukocytosis & a left shift are common findings. Specimens of peripheral blood & synovial fluid should be obtained before antibiotics are administered. Blood cultures are positive in up to 50 percent of S. aureus infections but are less frequently positive in infections due to other organism. The synovial fluid is turbid, serosanguineous, or frankly purulent. Cultures of synovial fluid are positive in more than 90 percent of cases. Prompt administration of systemic antibiotics & drainage of the involved joint can prevent destruction of cartilage, postinfectious degenerative arthritis, joint instability, or deformity. A third-generation cephalosporin such as cefotaxime (1 g every 8 h) an oxacillin (2 g every 4 h) will provide adequate coverage for most infections.
493. (F) The polymyalgia rheumatica syndrome is characterized by stiffness, aching, & pain in the muscles of the neck, shoulders, lower back, hips, & thighs. In patients with involvement of the temporal artery, headache is the predominant symptom & may be associated with a tender, thickened, or nodular artery, which may pulsate early in the disease but become occluded later. Scalp pain & claudication of the jaw & tongue may occur. A well-recognized & dreaded complication of temporal arteritis, particularly in untreated patients, is ocular involvement due primarily to ischemic optic neuritis, which may lead to serious visual symptoms, even sudden blindness in some patiens. Characteristic laboratory findings in addition to the elevated ESR include a normochromic or slightly hypochromic anaemia. Levels of enzymes indicative of muscle damage such as serum creatine kinase are not elevated. The diagnosis is confirmed by biopsy of the temporal artery. Since involvement of the vessel may be segmental, the diagnosis may be missed on routine biopsy; serial sectioning of biopsy specimens is recommended. Temporal arteritis & its associated symptoms are sensitive to glucocorticoid therapy.
494. (J) Rheumatoid arthritis RA most often causes symmetric arthritis with characteristic involvement of certain specific joints such as the proximal in terphalangeal & metacarpophalangeal joints. The distal interphalangeal joints are realer involved. Synovitis of the wrist joints is a nearly uniform feature of RA & may lead to limitation of motion, deformity, & median nerve entrapment (carpal tunnel syndrome). Characteristic deformities of the hand include “Z” deformity, swan-neck deformity & boutonnière deformity Rheumatoid nodules develop in 20 to 30 percent of persons with Ra. Clinical weakness & atrophy of skeletal muscle are common. Rheumatoid vasculitis can cause polyneuropathy & mononeuritis multiplex, cutaneous ulceration & dermal necrosis, digital gangrene, & visceral infarction. Pleuropulmonary manifestations, which are more commonly observed in men, include pleural disease, interstitial fibrosis, pleuropulmonary nodules, pneumonitis, & arteritis. Rheumatoid factors, which are autoantibodies reactive with the Fc portion of 1gG, are found in more than two-thirds of adults with the disease. Widely utilized test largely detec IgM rheumatoid factors. The presence of rheumatoid factor does not establish the diagnosis of RA but can be of prognostic significance. The erythrocyte sedimentation rate is increased in nearly all patients with active RA. Juxta-articular osteopenia may become apparent within weeks of onset. Loss of articular cartilage & bone erosion develop after months of sustained activity.
495. (D) Osteochondritis dissecans.
