In which part of the body is conjugated bilirubin metabolised to urobilinogen?
Your Answer: Hepatic sinusoids
Correct Answer: Large intestine
Explanation:Urobiligen is produced by the action of bacteria on bilirubin in the intestine. As a reminder, unconjugated bilirubin becomes conjugated in the hepatocyte. Conjugated bilirubin goes through enterohepatic circulation. About half of the urobiligen is reabsorbed and excreted by the kidneys in the urine. The rest is converted to stercobilinogen –> stercobilin, which is excreted in stool, giving it its brown colour.

A 32-year-old woman was referred for endoscopy and found to have a duodenal ulcer and a positive urease test. She was given lansoprazole, amoxicillin and clarithromycin for 7 days. Which of the following is the most appropriate way of determining the successful eradication of H. pylori?
Your Answer: Urea breath test
Explanation:Urea breath test is the most sensitive test to determine if there has been RESOLUTION/ERADICATION of the infection with H. pylori. The best test for initial diagnosis would be EGD with biopsy.

Which of the following is most commonly associated with the development of pseudomembranous colitis?
Your Answer: Ciprofloxacin
Correct Answer: Cefuroxime
Explanation:Pseudomembranous colitis is caused by a C. difficile infection that causes membranes to form on the colon wall. It is caused most commonly by broad-spectrum antibiotics. This would include cephalosporins, broad-spectrum penicillin, and clindamycin. Macrolides and quinolones have also been reported as potential aetiologies, but much less commonly.

Question 6
Correct
-
An 82-year-old woman is brought in by her carer with fluctuating consciousness. On examination she is deeply jaundiced, hypotensive with a tachycardia and has a hepatic flap. Initial blood tests reveal an ALT of 1000 U/l, INR 3.4, ALP 600 U/l and a bilirubin of 250 mmol/l. Repeat blood tests 6 hours later show an ALT of 550 U/l, INR 4.6, ALP 702 U/l and bilirubin of 245 m mol/l. The toxicology screen for paracetamol and aspirin is negative; she is positive for hepatitis B surface antibody and negative for hepatitis B surface antigen. Which of the following would best explain her clinical condition?
Your Answer: Acute liver failure secondary to paracetamol
Explanation:Liver flap is pathognomonic for liver failure. Paracetamol (also known as acetaminophen) overdose usually presents with symptoms including liver failure, resulting in confusion, jaundice, and coagulopathy a few days after overdose. The first 24 hours, people usually have minimal symptoms. Diagnosis is based on blood levels of acetaminophen at specific times after it was taken (see reference). If she took it a few days ago, levels may indeed be undetectable. The hepatitis B serology suggests prior vaccination. Wilson’s disease is not the most likely diagnosis given her presentation. The AST:ALT ratio would be expected to be reversed in alcohol induced liver failure.

A 45-year-old female develops profuse watery diarrhoea with lower abdominal pain seven days after undergoing laparoscopic cholecystectomy. What is the most likely diagnosis?
Your Answer: Abdominal sepsis
Correct Answer: Pseudomembranous colitis
Explanation:Pseudomembranous colitis is caused by a C. difficile infection that causes membranes to form on the colon wall. It is caused most commonly by broad-spectrum antibiotics. This would include cephalosporins, broad-spectrum penicillin, and clindamycin. Macrolides and quinolones have also been reported as potential aetiologies, but much less commonly. This woman would have received antibiotics prophylactically before her surgery, predisposing her to a possible c difficile infection. This is a much better answer choice than pseudo obstruction, abdominal sepsis, bile acid diarrhoea, and campylobacter gastroenteritis simply based on history of present illness.

A 16-year-old female presents with a two day history of right iliac fossa pain, nausea and loss of appetite. You suspect that she has acute appendicitis. Which scoring system could you use to lend support to your diagnosis?
Your Answer: Alvarado score
Explanation:The prompt is suggestive of acute appendicitis. The Alvarado score is a clinical scoring system used to determine the likelihood of appendicitis, so this is the correct answer. A score greater than 6 is generally considered at risk for having acute appendicitis. It has 8 different criteria included (symptoms, signs, and lab results) and divides patients into appendicitis unlikely, possible, probable, and definite. The Center Score is a score to access the likelihood that pharyngitis is due to Strep. The Child-Pugh score predicts prognosis in liver cirrhosis. The Glasgow score is two different scores– the Glasgow coma score in trauma, which estimates level of consciousness, essentially, and The Glasgow Imrie Criteria which determines the severity of acute pancreatitis based on 8 lab values. The MELD score predicts the severity of end-stage liver disease.

A 55-year-old lady, known with rheumatoid arthritis, complains of increasing numbness and tingling in her feet and hands. She has recently developed an ulcer on her left heel, after having burnt her foot in a hot bath. A number of depigmented areas are readily seen over her upper limbs. She is currently taking low-dose prednisolone (7.5 mg daily), alendronic acid, lansoprazole, paracetamol, indomethacin, methotrexate and rituximab. Her blood tests demonstrate: Haemoglobin 9.9 g/l, MCV 102 fl, Platelets 410 x 109/L, White blood cells 12.3 x 109/L, Vitamin B12 97 pg/ml, Folate 12.3ng/ml, Random blood glucose 9.9 mmol/L, Thyroid-stimulating hormone 4.7 mU/ml, Thyroxine 12.8 pmol/L. Which autoantibody would be most diagnostic for the underlying disease?
Your Answer: Antitissue transglutaminase (TTG)
Correct Answer: Anti-intrinsic factor (IF)
Explanation:This clinical scenario describes pernicious anaemia. Anti-intrinsic factor (IF) antibodies are most specific for pernicious anaemia. Antigastric parietal cell antibodies have a higher sensitivity but are less specific for pernicious anaemia. The other antibodies listed are not related to pernicious anaemia. Anti-TTG is seen with Celiac’s disease, anti-TPO is seen with thyroid disease, GAD is seen with type I diabetes, but this does not explain her anaemia.

A 28-year-old woman is investigated for bloody diarrhoea which started around six weeks ago. She is currently passing 3-4 loose stools a day which normally contain a small amount of blood. Other than feeling lethargic she remains systemically well with no fever or significant abdominal pain. A colonoscopy is performed which shows inflammatory changes in the ascending colon consistent with ulcerative colitis. Bloods show the following: Hb: 14.2 g/dL, Platelets: 323 * 109/L, WBC: 8.1 * 109/L, CRP: 22 mg/l. What is the most appropriate first-line medication to induce remission?
Your Answer: Oral prednisolone
Correct Answer: Oral aminosalicylate
Explanation:Given she is not showing signs of systemic illness, you do not need to treat for an acute flair (which would be steroids), but you need to put her on maintenance medication. Oral ASA would be the best option for this, it is first line. You cannot give rectal ASA because the location of her disease is in the ascending colon and the enema will not reach.

A 42-year-old man with alcoholic liver disease is admitted with pyrexia. He has been unwell for the past three days and has multiple previous admissions before with variceal bleeding. Examination shows multiple stigmata of chronic liver disease, ascites and jaundice. Paracentesis is performed with the following results: Neutrophils 487 cells/ul. What is the most appropriate treatment?
Your Answer: Intravenous cefotaxime
Explanation:This describes a clinical scenario of spontaneous bacterial peritonitis. The diagnosis is made when fluid removed (ascites) is found to have > 250/mm cubed of PMNs (polymorphonuclear leukocytes). Cefotaxime or another third generation cephalosporin is the treatment of choice.

A 33-year-old man with a known history of alcoholic liver disease is reviewed following a suspected oesophageal variceal haemorrhage. He has been resuscitated and intravenous terlipressin has been given. His blood pressure is now 104/60 mmHg and his pulse is 84/min. What is the most appropriate intervention?
Your Answer: Endoscopic variceal band ligation
Explanation:The correct course of action after giving terlipressin and resuscitating with IV fluids is to perform an EGD with endoscopic variceal band ligation. According to NICE: ‘Offer endoscopic variceal band ligation for the primary prevention of bleeding for people with cirrhosis who have medium to large oesophageal varices. There are serious complications of a TIPS procedure and it is not the first line treatment.

A 27 year old woman presents with diarrhoea. She has had a previous ileal resection for Crohn's Disease. Her inflammatory markers are normal. What is the most likely cause of her diarrhoea?
Your Answer: Gastroenteritis
Correct Answer: Bile Acid Malabsorption
Explanation:The question describes a patient who has had an ileal resection. Bile acids are reabsorbed in the distal ileum. Since this has been resected in this patient, one would expect her to have malabsorption of bile acids, causing her diarrhoea. This is a more likely correct answer than a Crohn’s flare, bacterial overgrowth, gastroenteritis, or tropical sprue, given the details included in the question prompt.

A 62-year-old female with a history of COPD and hypertension presents with pain on swallowing. Current medication includes a salbutamol and becotide inhaler, bendrofluazide and amlodipine. What is the most likely cause of the presentation?
Your Answer: Oesophageal candidiasis
Explanation:The history gives you a woman who is on inhaled steroid therapy. It is always a good idea for patients to rinse their mouths well after using inhaled steroids. Odynophagia (pain on swallowing) is a symptom of oesophageal candidiasis, which is the most likely answer given the steroids. Typically, you might see this in someone who is immunocompromised (classically, in HIV+ patients).

Which one of the following is most associated with the development of acute pancreatitis?
Your Answer: Hypercholesterolaemia
Correct Answer: Hyperchylomicronaemia
Explanation:Hyperchylomicronaemia is an increase (markedly) in chylomicrons, and this can cause acute pancreatitis, as well as xanthomas. It can be seen in familial lipoprotein lipase (LPL) deficiency, primary type V hyperlipoproteinemia, idiopathic hyperchylomicronaemia, and familial apolipoprotein CII deficiency. Treatment is dietary fat restriction in order to avoid pancreatitis attacks.

A 17-year-old boy presents with a 2 day history of colicky abdominal pain, vomiting and diarrhoea. He has been passing blood mixed with diarrhoea. He has no significant past medical history and takes no regular medication. On examination he is pyrexial and clinically dehydrated. Cardiorespiratory and abdominal examinations are normal. What is the most likely diagnosis?
Your Answer: Campylobacter infection
Explanation:The patient has bloody diarrhoea that sounds like a food poisoning in the clinical scenario. Campylobacter is the most common cause of this in the United Kingdom. This is then followed by Salmonella and Shigella. The symptoms are usually self limiting. This is more likely to be bacterial from the food than a viral gastroenteritis.

A 37-year-old social worker is referred to you with a long history of diarrhoea and abdominal discomfort. She was diagnosed with irritable bowel syndrome 10 years ago and takes mebeverine, peppermint tablets and Gaviscon. She is a vegetarian and rarely drinks or smokes. Examination of all systems is normal. Her blood tests show macrocytic anaemia. An upper gastrointestinal endoscopy reveals oesophagitis, hypertrophy of the gastric body and multiple duodenal ulcers. What is the most likely diagnosis?
Your Answer: Zollinger–Ellison syndrome
Explanation:This case describes Zollinger-Ellison syndrome. It is characterized by refractory peptic ulcer disease, often multiple ulcers. This is typically caused by secretion of gastrin from a gastrinoma, a neuroendocrine tumour. The most common site of ulceration is the duodenum. A symptom of a pancreatic gastrinoma may be steatorrhea from the hypersecretion of gastrin. Serum gastrin levels > 1000 and a pH < 2 are diagnostic of pancreatic gastrinoma. None of the other answer choices are a better answer than this. CT abdomen may potentially show a tumour, but this is not diagnostic for type.

A 47-year-old man is seen in clinic with a 3 month history of chronic epigastric discomfort. The pain comes and goes and radiates to his back and his right shoulder tip at times. It is worse after meals but there is no relieving factor. He feels nauseous most of the time and has foul-smelling stools. He has lost 2 stones in weight. He also complains of intermittent light-headedness. He drinks a bottle of wine on most nights and smokes 20 cigarettes /day. On examination, he is thin and looks neglected. His abdomen is soft, but tender on deep palpation in the epigastric area. He has a 2 cm non-tender liver edge. He also has decreased sensation to light touch on both feet. Bloods: sodium 131 mmol/L, potassium 4.2 mmol/L, creatine 64 ÎĽmol/L, amylase 35 U/l, alanine aminotransferase (ALT) 104 U/l, alkaline phosphatase (ALP) 121 U/l, bilirubin 24 ÎĽmol/L, calcium 2.01 mmol/L, whole cell count (WCC) 12.1 Ă— 109/L, haemoglobin (Hb) 10.2 g/dL, platelets 462 Ă— 109/L. Abdominal X-ray (AXR) was normal and oesophago-gastro duodenoscopy (OGD) showed mild gastritis. Campylobacter-like organism (CLO) test negative. Ultrasound abdomen showed a mildly enlarged liver with fatty change, spleen and kidneys normal, pancreas partially obscured by overlying bowel gas. 72-h stool fat was 22 g in 72 h. He is referred for a secretin test: volume collected 110 ml, bicarbonate 52 mEq/l. What is the most likely diagnosis?
Your Answer: Chronic pancreatitis
Explanation:The question describes an alcohol abusing man with chronic epigastric discomfort, radiating into his back, worse with meals, and foul-smelling stools, weight loss, as well as chronic nausea. This is likely, thus chronic pancreatitis due to alcohol abuse. Hepatomegaly and peripheral neuropathy secondary to anaemia support the diagnosis of long term alcohol abuse. Bacterial overgrowth may present with diarrhoea and is a less likely diagnosis than pancreatitis. Celiac disease is a less likely diagnosis than pancreatitis, and you would also expect mention of diarrhoea. VIPoma would also likely present with diarrhoea. Cecal carcinoma would more than likely present with blood in the stool.

A 25-year-old woman is reviewed in clinic. She was previously treated with omeprazole, amoxicillin and clarithromycin for Helicobacter pylori (H. pylori). She remains on PPI therapy but continues to have epigastric discomfort. You suspect she has ongoing H. pylori infection and request a urea breath test to investigate this. How long would the patient need to stop her PPI therapy before the urea breath test?
Your Answer: 14 days
Explanation:PPI will affect the accuracy of the test. In general, most recommend discontinuing PPI therapy for 2 weeks prior to a urea breath test. PPI’s have an anti-H. pylori effect.

A 72-year-old woman presents with a 3 month history of colicky abdominal pain after eating, and diarrhoea. She has lost 7 kg in weight over the last few months. A recent gastroscopy and colonoscopy were normal. Her past medical history includes angina and a right carotid endarterectomy at the age of 62 years. Her current medication includes aspirin, atenolol, simvastatin and losartan. right carotid endarterectomy at the age of 62 years. Her current medication includes aspirin, atenolol, simvastatin and losartan. Blood tests revealed: Haemoglobin (Hb) 118 g/l, Mean corpuscular volume (MCV) 80 fl, White cell count (WCC) 12.3 x 109/L, Platelets 210 x 109/L, Na+ 133 mmol/L, K+ 5.2 mmol/L, Urea 8.1 mmol/L, Creatinine 134 mmol/L. Select the most appropriate further investigations.
Your Answer: Gastroscopy
Correct Answer: Contrast-enhanced computed tomography (CT) of the abdomen
Explanation:The patient is 74 years old. She has had a recent gastroscopy and colonoscopy. She has a history of angina and a right CEA. She is having colicky abdominal pain after meals and weight loss, which points to a possible diagnosis of chronic mesenteric ischemia. Thus, you would want to do a contrast-enhanced CT scan of the abdomen to look for this. A 24 hour cardiac monitor would also be helpful to look for any abnormal rhythm that could be a potential aetiology of her disease.

Which one of the following is not associated with non-alcoholic steatohepatitis?
Your Answer: Type 1 diabetes mellitus
Explanation:There are two types of Non-alcoholic fatty liver disease (NAFLD); simple fatty liver and non-alcoholic steatohepatitis (NASH). Simple fatty liver and NASH are two separate conditions.
Simple fatty liver, also called non-alcoholic fatty liver (NAFL), is a form of NAFLD in which you have fat in your liver but little or no inflammation or liver cell damage. Simple fatty liver typically does not progress to cause liver damage or complications.
Non-alcoholic steatohepatitis (NASH)
NASH is a form of NAFLD in which you have hepatitis and liver cell damage, in addition to fat in your liver. Inflammation and liver cell damage can cause fibrosis, or scarring, of the liver. NASH may lead to cirrhosis or liver cancer. Type I diabetes is not associated with NASH (non-alcoholic steatohepatitis), but type II diabetes is. Hyperlipidaemia, obesity, sudden weight loss/starvation and jejunoileal bypass are all associated with NASH. This is the most common cause of liver disease in the developed world. -

Your Answer: Trial of dairy-free diet
Explanation:The best next step is to try a dairy-free diet, many patients may develop this in their lifetime. IBS is a diagnosis of exclusion, and one would need to rule lactose intolerance out as a potential aetiology first. She is only 28, and without overt bleeding or signs/sxs/labs suggestive of obstruction or inflammation; colonoscopy, flex sig and a barium enema are not indicated.

A 35-year-old gentleman with a history of alcohol excess presents to hospital with progressive abdominal distension. He now complains of early satiety and abdominal discomfort as a result of the distension. Examination reveals a significantly distended abdomen with shifting dullness. A diagnostic ascitic tap is performed and the fluid sent for analysis. What is the most appropriate first line treatment for his ascites?
Your Answer: Dietary salt restriction
Correct Answer: Paracentesis
Explanation:The first line treatment for ascites that is symptomatic is paracentesis. If it is not symptomatic, treatment could be with salt and fluid restriction as well as spironolactone. If spironolactone maximum dosage is reached, you can use furosemide additionally. Amiloride is not a diuretic that is recommended in this case.

A 76-year-old woman is admitted with a productive cough and pyrexia. Chest x-ray shows a pneumonia and she is commenced on intravenous ceftriaxone. Following admission a stool sample is sent because of diarrhoea. This confirms the suspected diagnosis of Clostridium difficile diarrhoea and a 10-day course of oral metronidazole is started. After 10 days her diarrhoea is ongoing but she remains clinically stable. What is the most appropriate treatment?
Your Answer: IV vancomycin for 3 days
Correct Answer: Oral vancomycin for 14 days
Explanation:When a patient fails treatment with metronidazole (Flagyl) treatment, the next course of action is to change to oral vancomycin, which is shown to be effective in the treatment of c diff colitis. Oral rifampicin is not a treatment for c diff. Oral metronidazole is not resolving her symptoms so is not the correct answer. clindamycin is a cause of c diff colitis, not a treatment. IV Vanc is not active in the gut so is not the treatment; oral is active in the gut.

A 55-year-old obese woman presents to casualty. She has rigors and reports a fever. On examination there is jaundice and tenderness over the right upper quadrant of her abdomen. She has an elevated white blood cell count and a markedly raised alkaline phosphatase level; transaminases and bilirubin are also abnormal. Which of these diagnoses best fits the clinical picture?
Your Answer: Acute hepatitis
Correct Answer: Ascending cholangitis
Explanation:This question describes Charcot’s triad– fever, RUQ pain, and jaundice, which is seen in ascending cholangitis. Reynold’s pentad is a worsened version of this, where you have RUQ pain, fever, jaundice, hypotension, and altered mental status. Risk factors for gallstones are the 4F’s- female, fat, forty, and fertile. You would not have the elevated bilirubin, ALP, transaminases with a kidney stone or in peptic ulcer disease. Hepatitis would not cause elevation of bilirubin.

A 63 year old man presents with painless jaundice and weight loss over the last few months. He is a heavy smoker and has a past medical history of COPD. On examination his abdomen is soft and non tender and he is clearly icteric. His bloods reveal deranged LFTs with an alkaline phosphates of 240 and a bilirubin of 92, ALT and AST are both around 200. An ultrasound of his abdomen is performed and shows both intra and extrahepatic bowel duct dilatation within the liver. What`s the first line investigation of his case?
Your Answer: ERCP
Correct Answer: MRCP
Explanation:When you hear painless jaundice and weight loss in the same sentence, the first thing you should think is cancer. Likely cholangiocarcinoma here or some other biliary tract obstructing cancer. The first line imaging for this would be MRCP because you’re looking for obstruction– the dilatation of the intra and extrahepatic ducts suggests this. This is less invasive than an ERCP or a liver biopsy. CT C/A/P will likely be needed for staging later but it is asking for the initial test.
