A 52 year old man undergoes a renal transplant from a living related donor. He is well for the first five months, but on review in the renal clinic, he is noted to have persistent hypertension and a slight deterioration in renal function. What is the best explanation for this?
Your Answer: Renal artery stenosis
Explanation:Transplant renal artery stenosis (TRAS) is a well-recognized vascular complication after kidney transplant. It occurs most frequently in the first 6 months after kidney transplant, and is one of the major causes of graft loss and premature death in transplant recipients. Transplant renal artery stenosis (TRAS) is the narrowing of the transplant renal artery, impeding blood flow to the allograft. It accounts for 1–5% cases of post-transplant hypertension. Patients with TRAS have activated RAAS and usually present with worsening or refractory hypertension, fluid retention and/or allograft dysfunction without evidence of rejection.
Percutaneous transluminal angioplasty with stent placement is generally the first-line therapy to correct hemodynamically significant stenosis in TRAS, especially for lesions that are short, linear and distal to the anastomosis. -

A 46 -year old patient diagnosed with chronic rhinosinusitis, was to undergo surgery to improve drainage from his frontal sinus to the nose. Which is a route that one would take to enter into the frontal sinus through the nasal cavity?
Your Answer: Middle meatus
Explanation:The middle meatus is a nasal passageway located inferior to the middle concha and superior to the inferior concha. On the superior aspect of this meatus is a bulge produced by the middle ethmoidal cells known as the bulla ethmoidalis. Below this bulge is a curved fissure, the hiatus semilunaris, which is also bordered inferiorly by the edge of the uncinate process of the ethmoid. It is through this curved fissure, hiatus semilunaris, that the middle meatus communicates with the frontal sinus. It first forms a communication with a curved passage way known as the infundibulum. The infundibulum anteriorly communicates with the anterior ethmoidal cells and continues upward as the frontonasal duct into the frontal sinus.

A 27-year old lady presented with dull, abdominal pain and some pain in her lower limbs. On enquiry, it was revealed that she has been suffering from depression for a few months. Physical examination and chest X-ray were normal. Further investigations revealed serum calcium 3.5 mmol/l, albumin 3.8 g/dl and phosphate 0.65 mmol/l. What is the diagnosis?
Your Answer: Pituitary adenoma
Correct Answer: Parathyroid adenoma
Explanation:Hypercalcaemia with hypophosphatemia indicates parathyroid disorder and adenomas are more common than hyperplasia. In this young age group, metastatic disease is unlikely. Solitary adenomas are responsible for 80-85% cases of primary hyperparathyroidism. 10-15% cases are due to parathyroid hyperplasia and carcinomas account for 2-3% cases. Symptoms include bone pain (bones), nephrolithiasis (stones), muscular aches, peptic ulcer disease, pancreatitis (groans), depression (moans), anxiety and other mental disturbances.

A 52-year-old male who is a known case of leukaemia visits the day unit for a blood transfusion. Five days later, he presents to the emergency department with a temperature of 38.5°C, and erythematous cutaneous eruptions.What is the most likely explanation?
Your Answer: Graft-versus-host disease
Explanation:This is transfusion-associated graft-versus-host disease (GvHD) occurring in an immunosuppressed patient. It can occur 4–30 days after a transfusion and follows a subacute pathway. Patients may also have diarrhoea and abnormal liver function tests. Management involves steroid therapy.
Acute transfusion reactions present during or within 24 hours of a blood transfusion. The most frequent clinical features are fever, chills, pruritus, or urticaria, which typically resolve promptly without specific treatment or complications. Other signs occurring in temporal relationship with a blood transfusion such as severe dyspnoea, pyrexia, or loss of consciousness may be the first indication of a more severe, potentially fatal reaction.
Transfusion reactions may be immune-mediated and non-immune-mediated. GvHD is a condition that might occur after an allogeneic transplant. The donated blood cells view the recipient’s body as foreign and attacks it. Immunosuppressed patients who receive white blood cells from another person are at increased risk of developing GvHD.
There are two forms of the disease:
1. Acute graft-versus-host disease (aGvHD): usually presents with skin and/or liver and/or gut involvement.
2. Chronic graft-versus-host disease (cGvHD).The diagnosis is clinical and usually one of exclusion; however, biopsy of affected tissues may be helpful in unclear cases.

A 50-year-old man presents with bright red rectal bleeding that occurs post defecation and is noted on the toilet paper. It is also associated with severe pain. On external anal examination, a skin tag is identified at 6 o'clock position.Which of the following treatment options is most likely to be helpful?
Your Answer: Injections of oily phenol
Correct Answer: Topical GTN
Explanation:Since the most likely diagnosis is anal fissure, the correct treatment is topical nitrates.
Anal fissures are a common cause of painful, bright red rectal bleeding. Most fissures are idiopathic and present as a painful mucocutaneous defect in the posterior midline (90% cases). Fissures are more likely to be anteriorly located in females, particularly if they are multiparous. Diseases associated with fissure-in-ano include:
1. Crohn’s disease
2. Tuberculosis
3. Internal rectal prolapseDiagnostic options are as follows:
In most cases, the defect can be visualised as a posterior midline epithelial defect. Where symptoms are highly suggestive of the condition and examination findings are unclear, an examination under anaesthesia may be helpful. Atypical disease presentation should be investigated by colonoscopy and EUA, with biopsies of the area.For management of anal fissure:
1. Stool softeners are important as hard stools may tear the epithelium and result in recurrent symptoms. The most effective first-line agents are topically applied GTN (0.2%) or Diltiazem (2%) paste.
2. Resistant cases may benefit from injection of botulinum toxin or lateral internal sphincterotomy. Advancement flaps may be used to treat resistant cases. -

Bloody discharge from the nipple of a 40-year old woman with no obvious lump or abnormality on mammography is suggestive of:
Your Answer: Infiltrating ductal carcinoma
Correct Answer: Intraductal papilloma
Explanation:A small benign tumour, namely intraductal papilloma is most common in women between 35-55 years of age. It is also the commonest cause of spontaneous discharge from a single duct. A lump below the nipple may be sometimes palpable. Ultrasound and ductography are useful investigations., along with cytology of discharge to assess the presence of malignant cells. Confirmation is by breast biopsy.

A 32-year-old man presents with aching pain and discomfort in his right testicle. He has generally been feeling unwell for the past 48 hours as well. On examination, tenderness of the right testicle and an exaggerated cremasteric reflex has been found. What should be the appropriate course of action?
Your Answer:
Correct Answer: Administration of antibiotics
Explanation:This is likely a case of epididymo-orchitis which usually occurs due to infection with gonorrhoea or chlamydia in this age group (<35 years). Epididymo-orchitis is an acute inflammation of the epididymis and often involves the testis. It is usually caused by bacterial infection which spreads from the urethra or bladder. Amiodarone is a recognised non-infective cause of epididymitis, which resolves on stopping the drug. On examination, tenderness is usually confined to the epididymis, which may facilitate differentiating it from torsion where pain usually affects the entire testis.

A 45 year old lady has been diagnosed with Friedreich's ataxia that has affected her medial group of nuclei in the anterior horn of the spinal cord. Which of the following structures will have their muscles affected?
Your Answer:
Correct Answer: Axial muscles
Explanation:The cells in the anterior horn can be arranged in the following three main groups: medial, lateral and central. The medial group of nuclei in the anterior horn of the spinal cord are located along the entire length of the spinal cord and are responsible for the innervation of the axial muscles of the body ( muscles of the head and neck region). Thus this disease will most likely affect the functioning of the muscles of the head and neck.

The gradual depolarization in-between action potentials in pacemaker tissue is a result of?
Your Answer:
Correct Answer: A combination of gradual inactivation outward IK along with the presence of an inward ‘funny’ current (If) due to opening of channels permeable to both Na+ and K+ ions
Explanation:One of the characteristic features of the pacemaker cell is the generation of a gradual diastolic depolarization also called the pacemaker potential. In phase 0, the upstroke of the action potential caused by an increase in the Ca2+ conductance, an influx of calcium occurs and a positive membrane potential is generated. The next is phase 3 which is repolarization caused by increased K+ conductance as a result of outwards K+ current. Phase 4 is a slow depolarization which accounts for the pacemaker activity, caused by increased conductance of Na+, inwards Na+ current called IF. it is turned on by repolarization.

A 32 year old woman who works as a teacher presents with a swollen, oedematous leg. She hails from Africa, from an area that is poorly sanitized and prevalent with mosquitoes. She travelled to England two weeks back. Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Filariasis
Explanation:Lymphatic filariasis, commonly known as elephantiasis, is a painful and profoundly disfiguring disease. In communities where filariasis is transmitted, all ages are affected. While the infection may be acquired during childhood its visible manifestations may occur later in life, causing temporary or permanent disability. The disease is caused by three species of thread-like nematode worms, known as filariae – Wuchereria bancrofti, Brugia malayi and Brugia timori. Male worms are about 3–4 centimetres in length, and female worms 8–10 centimetres. The male and female worms together form “nests” in the human lymphatic system.
Filarial infection can cause a variety of clinical manifestations, including lymphoedema of the limbs, genital disease (hydrocele, chylocele, and swelling of the scrotum and penis) and recurrent acute attacks, which are extremely painful and are accompanied by fever. The vast majority of infected people are asymptomatic, but virtually all of them have subclinical lymphatic damage and as many as 40% have kidney damage, with proteinuria and haematuria.

Which of the following is not seen as a complication of wound healing?
Your Answer:
Correct Answer: Malignancy
Explanation:Complications in wound healing can originate due to abnormalities in the repair process. These abnormalities are :
1) Deficient scar formation: insufficient granulation tissue can lead to wound dehiscence and ulceration. Dehiscence or wound rupture is seen most commonly in abdominal surgery due to increased intraabdominal pressure. Ulcerations are common in extremity wounds due to inadequate vascularization.
2) Excessive formation of repair components: collagen being laid down may begin normally however later lead to a raised scar also called a hypertrophic scar, which can extend beyond its boundaries to form a keloid and
3) Formation of contractures. -

An 8 year old boy presents with a history of repeated bacterial/pyogenic infections. He had a normal recovery from chickenpox and measles and shows normal antibody response. A decrease in which of the cell types can best explain this history of repeated pyogenic infections?
Your Answer:
Correct Answer: Neutrophils
Explanation:A decrease in the number of granulocytes, particularly neutrophils is known as agranulocytosis and it increases the susceptibility of an individual towards recurrent infections. Neutropenia can be either due to decreased production or increased elimination of neutrophils.
Ineffective agranulopoiesis is seen in: 1. myeloid stem cell suppression, 2. disease conditions associated with granulopoiesis such as megaloblastic anaemia and myelodysplastic syndromes, 3. rare genetic diseases, 4. splenic sequestration and 5. increased peripheral utilization. -

Urine examination showed >300 mg/dl proteinuria (4+) and 24-hour urine protein 3.5g. No glucose, blood, nitrites, urobilinogen or casts were present in urine. What is the most likely diagnosis?
Your Answer:
Correct Answer: Membranous glomerulonephritis
Explanation:Membranous glomerulonephritis or nephropathy, is a renal disorder with insidious course and usually affects people aged 30-50 years. 85% cases are primary (or idiopathic). The other 15% are secondary to autoimmune conditions like SLE, infections like malaria or hepatitis B, drugs like captopril and NSAIDs, or malignancies (particularly lung or colonic carcinoma). This disease is caused due to circulating immune complexes which are said to form by binding of antibodies to antigens in glomerular basement membrane. This antigens could be endogenous or derived from systemic circulation. This immune complex triggers the complement system, resulting in formation of membrane attack complex (MAC) on glomerular epithelial cells. This further results in release of proteases and oxidants which damage the capillaries making them ‘leaky’. Moreover, the epithelial cells also secrete a mediator to reduce nephron synthesis and distribution.

A 55-year-old male presents with an ulcerated mass at the anal verge. A biopsy is taken and the histology demonstrates as squamous cell carcinoma. Which of the following viral infection is most likely to have contributed to the development of the condition?
Your Answer:
Correct Answer: Human papillomavirus 16
Explanation:Anal squamous cell cancer is believed to be directly linked to the presence of a complex inflammatory process most commonly caused by HPV infection (particularly with serotypes 16 and 18) in the histologically unique area of the anal squamocolumnar epithelium. In one Scandinavian study, serotype 16 HPV DNA was detected in 73% of anal cancer specimens, and serotype 16, 18, or both were detected in 84% of specimens. In contrast, no rectal cancer specimens contained HPV DNA.

The specialist registrar, while performing the repair of an infrarenal abdominal aortic aneurysm, decides not to re-implant the inferior mesenteric artery into the repaired abdominal aorta. She says that an anastomotic artery running along the border of the large intestine is good enough to supply blood to the territory of the inferior mesenteric artery. Which vessel is she referring to?
Your Answer:
Correct Answer: Marginal
Explanation:The marginal artery is a key anastomosis for the large intestine that runs around the border of the large intestine and is formed by the anastomosis of the branches of the ileocolic artery, right colic artery, middle colic artery, left colic artery and sigmoid artery. If a small artery is occluded, these branches allow blood to reach all segments of the colon.
The arcades are anastomotic loops between the arteries that provide alternative pathways for blood flow. They are more prominent in the small intestine than the large intestine.
Arteriae rectae are small branches that run from the marginal artery to reach the colon.
The ileocolic artery is the branch of the superior mesenteric artery that supplies the caecum, appendix and terminal part of the ileum.
The coronary arteries supply blood to the heart. -

A 30-year-old male complains of pain and weakness in the shoulder. He has recently been unwell with glandular fever from which he is fully recovered. On examination, there is some evidence of muscle wasting and a degree of winging of the scapula. Power during active movements is impaired. What is the most likely cause?
Your Answer:
Correct Answer: Parsonage-Turner syndrome
Explanation:Parsonage-Turner Syndrome (PTS), also referred to as idiopathic brachial plexopathy or neuralgic amyotrophy, is a rare disorder consisting of a complex constellation of symptoms with abrupt onset of shoulder pain, usually unilaterally, followed by progressive neurologic deficits of motor weakness, dysesthesias, and numbness. Although the aetiology of the syndrome is unclear, it is reported in various clinical situations, including postoperatively, postinfectious, posttraumatic, and postvaccination.
The most common associated risk factor is a recent viral illness.
The pain is not positional and usually worse at night and may be associated with awakenings from sleep. There are typically no constitutional symptoms associated with the syndrome. The duration of pain is almost always self-limiting, lasting 1 to 2 weeks, but on rare occasion persisting for longer periods.
In the earliest stages of this condition (the first few weeks), pain management with opiates, NSAIDs, and neuroleptics is the mainstay of treatment. Acupuncture and transcutaneous electrical nerve stimulation (TENS) can also be adjuncts to medications. Oral steroids have been recommended by some, but there is poor literature evidence to support its efficacy.
Physical therapy plays an important role in the treatment of this condition. Modalities such as TENS can help in pain management. -
