During a splenectomy procedure of a 45-year old male patient with a bleeding ruptured spleen, the surgeon decided to clamp the splenic artery near the coeliac trunk to stop the bleeding. Which of the following organ/s parts will be least affected by the clamping?
Your Answer: Greater omentum
Correct Answer: Duodenum
Explanation:The duodenum is the only organ in the list that would not be affect by the clumping of the splenic artery as it is supplied by common hepatic artery (through the gastroduodenal artery) and the superior mesenteric artery (through the inferior pancreaticoduodenal artery). The splenic artery is the artery that supplies the spleen with oxygenated blood. The splenic artery before reaching the spleen also gives off branches that supply the stomach and the pancreas. The greater curvature and the fundus of the stomach is supplied the short gastric artery which branches off from the splenic artery. The left portion of the greater curvature of the stomach together with the greater omentum is supplied by the left gastro-omental artery of the splenic artery. The body and tail of the pancreas is supplied by branches of the splenic artery through the dorsal and superior pancreatic arteries and the caudal pancreatic arteries respectively.

A 3 year old boy is taken to the doctor by his mother who has noticed that he has been having rectal bleeding for a few months and a cherry red lesion appeared at the anal verge after defecation. Which of the following is most likely the diagnosis?
Your Answer: Anal fissure
Correct Answer: Juvenile polyp
Explanation:Juvenile polyps are benign hamartomas with neoplastic potential that are the most frequent gastrointestinal polyp of childhood, with the peak incidence between 3 and 5 years of age.. The presence of multiple juvenile polyps may indicate a premalignant condition commonly named juvenile polyposis coli or juvenile polyposis syndrome (JPS). In contrast, single or solitary juvenile polyps generally are considered benign sporadic lesions that confer little to no future risk of malignancy. Most frequent presentation is painless rectal bleeding. Other features include a prolapsing rectal mass and abdominal pain.

A blood sample of a 58 year old male patient, who underwent an abdominal aortic aneurysm repair, was sent to the laboratory. The laboratory technician said that the patient’s blood agglutinates with antisera anti-A and anti-D, while the patient’s serum agglutinates cells of blood group B. What is the blood group of this patient?
Your Answer: A negative D
Correct Answer: A positive
Explanation:Group A – has only the A antigen on red cells (and B antibody in the plasma)
Group B – has only the B antigen on red cells (and A antibody in the plasma)
Group AB – has both A and B antigens on red cells (but neither A nor B antibody in the plasma)
Group O – has neither A nor B antigens on red cells (but both A and B antibody are in the plasma). Many people also have a so-called Rh factor on the red blood cell’s surface. This is also an antigen and those who have it are called Rh+. A person with Rh– blood does not have Rh antibodies naturally in the blood plasma (as one can have A or B antibodies, for instance) but they can develop Rh antibodies in the blood plasma if they receive blood from a person with Rh+ blood, whose Rh antigens can trigger the production of Rh antibodies. A person with Rh+ blood can receive blood from a person with Rh– blood without any problems. In this scenario the person has blood group A+ as he has A antigen, anti B antibody and Rh antigen -

A 25-year-old man is involved in vigorous intercourse and suddenly feels a snap. His penis becomes swollen and painful immediately after. The admitting surgeon suspects a penile fracture. Which of the following is the most appropriate initial management?
Your Answer: Immediate surgical exploration
Explanation:Suspected penile fractures should be surgically explored and the injury repaired.
Penile fractures are a rare type of urological trauma. The injury is usually in the proximal part of the penile shaft and may involve the urethra. A classical history of a snapping sensation followed by immediate pain is usually given by the patient (usually during vigorous intercourse). On examination, a tense haematoma is most commonly noted, and if the urethra is injured, blood may be seen at the meatus.
The correct management involves surgical exploration and repair of the injury. A circumferential incision is made immediately inferior to the glans and the penile shaft is inspected. Injuries are usually sutured and the urethra is repaired over a catheter.

A 60-year old patient having a history of cholelithiasis that led to recurrent pain, bloating, nausea and vomiting, was scheduled for surgery to have the gallbladder removed. During the cholecystectomy, the SHO conducting the procedure accidentally punctured a blood vessel that lied immediately posterior to the omental foramen and blood filled the operating field. Which of the following blood vessels was the one likely punctured?
Your Answer: Aorta
Correct Answer: Inferior vena cava
Explanation:The omental foramen is the pathway that connects the greater peritoneal sac and the lesser peritoneal sac. The omental foramen is bordered posteriorly by the inferior vena cava. This is the blood vessel that would most likely be punctured. The aorta and its branch, the renal artery, lie postero-lateral to the omental foramen and are deeper than the inferior vena cava hence making them less likely to be injured. The hepatic portal vein, the hepatic artery and the superior mesenteric vein borders the omental foramen anteriorly and would not be injured by a jab on the posterior border of the omental foramen. Finally, the splenic artery is found in the splenorenal ligament that borders the omental foramen laterally to the left.

A patient is diagnosed with a tumour of the parotid gland. During surgical removal of the gland, which artery is vulnerable to injury?
Your Answer: Main trunk of cranial nerve VIII
Correct Answer: External carotid artery
Explanation:The external carotid artery is a major artery of the head and neck. It arises from the common carotid artery when it splits into the external and internal carotid artery. It supplies blood to the face and neck. The external carotid artery begins opposite the upper border of the thyroid cartilage and, taking a slightly curved course, passes upward and forward and then inclines backward to the space behind the neck of the mandible, where it divides into the superficial temporal and internal maxillary arteries. It rapidly diminishes in size in its course up the neck, owing to the number and large size of the branches given off from it. At its origin, this artery is more superficial and placed nearer the midline than the internal carotid and is contained within the carotid triangle. The external carotid artery is covered by the skin, superficial fascia, platysma, deep fascia and anterior margin of the sternocleidomastoid. It is crossed by the hypoglossal nerve, by the lingual, ranine, common facial and superior thyroid veins; and by the digastric and stylohyoid; higher up it passes deeply into the substance of the parotid gland, where it lies deep to the facial nerve and the junction of the temporal and internal maxillary veins. It is here that it is in danger during surgery of the parotid gland.

The mechanism of action of streptokinase involves:
Your Answer: Direct conversion of plasminogen to plasmin
Explanation:Streptokinase is an enzyme that is produced by group A beta haemolytic streptococcus and is an effective and cost efficient method for the dissolution of a clot used in cases of MI and pulmonary embolism. It works by directly converting plasminogen to plasmin which breaks down the blood components in the clot and fibrin, dissolving the clot. Streptokinase is a bacterial product and thus the body will develop immunity against it.

A 39-year-old woman who is a known case of acute myeloid leukaemia requires venous access for chemotherapy. Which of the following is the best option?
Your Answer:
Correct Answer: Groshong line
Explanation:Chemotherapy for acute myeloid leukaemia (AML) requires long-term therapy and multiple blood tests. Therefore, an indwelling device, such as Groshong line, is preferable.
Tunnelled lines such as Groshong and Hickman lines are popular devices for patients with long-term therapeutic requirements. These devices are usually inserted, using ultrasound guidance, into the internal jugular vein and then tunnelled under the skin. A cuff of woven material is sited near the end and helps to anchor the device into the tissues. These cuffs require formal dissection to allow the device to be removed.

A 45-year old with sarcoidosis has enlarged tracheobronchial lymph nodes. Which nerve is most likely to be irritated in this patient?
Your Answer:
Correct Answer: Left recurrent laryngeal
Explanation:Tracheobronchial lymph nodes are located at the bifurcation of the trachea and are in three groups i.e. the right superior, left superior and inferior. The aorta arches over the left bronchus near the point of tracheal bifurcation. Thus, the nerves that are closely associated with the aorta might be irritated if these nodes become inflamed. The left recurrent laryngeal nerve is such a nerve. The phrenic nerves, both the left and the right, are lateral and thus would not be affected. The right recurrent nerve loops around the right subclavian artery and is distant from this area. The right vagus artery is not associated with the aorta and the sympathetic chain is located in the posterior chest parallel to the vertebra, also not associated with the tracheobronchial tree.

A patient presents with loss of fine touch and sense of proprioception in the lower part of the body (below T6). He is likely to have a lesion involving:
Your Answer:
Correct Answer: Gracile nucleus
Explanation:The gracile nucleus is located in the medulla oblongata and is one of the dorsal column nuclei involved in the sensation of fine touch and proprioception. It contains second-order neurons of the dorsal column–medial lemniscus system, that receive inputs from sensory neurones of the dorsal root ganglia and send axons that synapse in the thalamus.
The gracile nucleus and fasciculus carry epicritic, kinaesthetic and conscious proprioceptive information from the lower part of the body (below the level of T6 in the spinal cord). Similar information from the upper part of body (above T6, except for face and ear) is carried by the cuneate nucleus and fasciculus. The information from face and ear is carried by the primary sensory trigeminal nucleus. -

After surgery, a patient developed a stitch granuloma . Which leukocyte in the peripheral blood will become an activated macrophage in this granuloma?
Your Answer:
Correct Answer: Monocyte
Explanation:Monocytes are leukocytes that protect the body against infections and move to the site of infection within 8-12 hours to deal with it. They are produced in the bone marrow and shortly after being produced are released into the blood stream where they circulate until an infection is detected. When called upon they leave the circulation and transform into macrophages within the tissue fluid and thus gain the capability to phagocytose the offending substance. Monocyte count is part of a complete blood picture. Monocytosis is the state of excess monocytes in the peripheral blood and may be indicative of various disease states. Examples of processes that can increase a monocyte count include: • chronic inflammation • stress response • hyperadrenocorticism • immune-mediated disease • pyogranulomatous disease • necrosis • red cell regeneration.

A patient who has used NSAIDS for many years presents to the A&E with symptoms of acute haemorrhagic shock. An emergency endoscopy is done that shows that a duodenal ulcer has perforated the posterior wall of the first part of the duodenum. Which artery is most likely to be the cause of the haemorrhage?
Your Answer:
Correct Answer: Gastroduodenal
Explanation:The gastroduodenal artery is a branch of the hepatic artery and descends near the pylorus between the first part of the duodenum and the neck of the pancreas to divide at the lower border of the duodenum into the right gastroepiploic and pancreaticoduodenal arteries. Before it divides, it gives off a few branches to the pyloric end of the stomach and to the pancreas. The artery that is most likely involved in this situation is the gastroduodenal artery since it is posterior to the first part of the duodenum.

A 21-year-old woman presents with intermittent diarrhoea for the past eight months and loss in weight of about two kilograms. Colonoscopy is carried out in which appearances of melanosis coli are identified. This is confirmed on biopsy. What could be the most likely cause of melanosis coli in this patient?
Your Answer:
Correct Answer: Laxative abuse
Explanation:Melanosis coli may have occurred as a result of laxative abuse in this patient.
Melanosis coli, also pseudomelanosis coli, is a disorder of pigmentation of the wall of the colon, often identified at the time of colonoscopy. It is benign, and may have no significant correlation with the disease. The brown pigment seen is lipofuscin in macrophages, not melanin.
According to the World Health Organisation (WHO), chronic diarrhoea is defined as lasting for more than 14 days. It is very common in irritable bowel syndrome (IBS). Patients may be divided into those with diarrhoea-predominant IBS and those with constipation-predominant IBS. Along with diarrhoea/constipation, clinical features such as abdominal pain, bloating, weight loss, change in bowel habit, lethargy, nausea, backache, and bladder symptoms are also seen. Bloody diarrhoea is more common in ulcerative colitis than in Crohn’s disease.

A 53 year old male presents with generalised right upper quadrant pain which started from the previous day. On admission, he is septic and jaundiced and there is tenderness in the right upper quadrant. What is the most likely diagnosis?
Your Answer:
Correct Answer: Cholangitis
Explanation:Acute cholangitis is a bacterial infection superimposed on an obstruction of the biliary tree most commonly from a gallstone, but it may be associated with neoplasm or stricture. The classic triad of findings is right upper quadrant (RUQ) pain, fever, and jaundice. A pentad may also be seen, in which mental status changes and sepsis are added to the triad.
A spectrum of cholangitis exists, ranging from mild symptoms to fulminant overwhelming sepsis. Thus, therapeutic options for patient management include broad-spectrum antibiotics and, potentially, emergency decompression of the biliary tree.
The main factors in the pathogenesis of acute cholangitis are biliary tract obstruction, elevated intraluminal pressure, and infection of bile. A biliary system that is colonized by bacteria but is unobstructed, typically does not result in cholangitis. It is believed that biliary obstruction diminishes host antibacterial defences, causes immune dysfunction, and subsequently increases small bowel bacterial colonization. Although the exact mechanism is unclear, it is believed that bacteria gain access to the biliary tree by retrograde ascent from the duodenum or from portal venous blood. As a result, infection ascends into the hepatic ducts, causing serious infection. Increased biliary pressure pushes the infection into the biliary canaliculi, hepatic veins, and perihepatic lymphatics, leading to bacteraemia (25-40%). The infection can be suppurative in the biliary tract. -

What's the nodal stage of a testicular seminoma if several lymph nodes between 2cm and 5cm are found?
Your Answer:
Correct Answer: N2
Explanation:According to the American Joint Committee on Cancer (AJCC) 2002 guidelines, the nodal staging of testicular seminoma is the following:
N0: no regional lymph node metastases
N1: metastasis with lymph nodes 2 cm or less in their greatest dimension or multiple lymph nodes, none more than 2 cm
N2: metastasis with lymph nodes greater than 2 cm but not greater than 5 cm in their greatest dimension, or multiple lymph nodes, any one mass greater than 2 cm, but not more than 5 cm
N3: metastasis with lymph nodes greater than 5 cm in their greatest dimension.
The patient in this case has N2 testicular seminoma. This TNM staging is extremely important because treatment options are decided depending on this classification. -

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.

Your Answer:
Correct Answer: Ilioinguinal nerve
Explanation:The ilioinguinal nerve arises together with the iliohypogastric nerve from the first lumbar nerve to emerge from the lateral border of the psoas major muscle just below the iliohypogastric and passing obliquely across the quadratus lumborum and iliacus muscles. It perforates the transversus abdominis, near the anterior part of the iliac crest and communicates with the iliohypogastric nerve between the internal oblique and the transversus. It then pierces the internal oblique to distribute filaments to it and accompanying the spermatic cord through the subcutaneous inguinal ring, is distributed to the skin of the upper and medial parts of the thigh, the skin over the root of the penis and the upper part of the scrotum in man and to the skin covering the mons pubis and labium majus in the woman. As the ilioinguinal nerve runs through the inguinal canal, it could easily be compressed by a hernial sac.
The femoral branch of genitofemoral nerve provides sensory innervation of the upper medial thigh.
The femoral nerve innervates the compartment of the thigh and also has some cutaneous sensory branches to the thigh.
The iliohypogastric nerve innervates the skin of the lower abdominal wall, upper hip and upper thigh. The subcostal nerve innervates the skin of the anterolateral abdominal wall and the anterior scrotal nerve is a terminal branch of the ilioinguinal nerve. -
