Question 1
Correct
-
A 45-year-old woman presents with sudden onset of constant abdominal pain. She tells you she has a history of peptic ulcers. The pain is worse with inspiration and movement.
On examination, there is rebound tenderness and guarding. There are absent bowel sounds. A chest X-ray shows free air under the diaphragm.
What clinical sign tells you that the peritonitis involves the whole abdomen and is not localised?Your Answer: Absent bowel sounds
Explanation:Understanding the Signs and Symptoms of Peritonitis
Peritonitis is a condition characterized by inflammation of the peritoneum, the membrane lining the abdominal and pelvic cavity. It can be caused by various factors, including organ inflammation, viscus perforation, and bowel obstruction. Here are some of the common signs and symptoms of peritonitis:
Absent Bowel Sounds: This is the most indicative sign of generalised peritonitis, but it can also be present in paralytic ileus or complete bowel obstruction.
Guarding: This is the tensing of muscles of the abdominal wall, detected when palpating the abdomen, which protects an inflamed organ. It is present in localised and generalised peritonitis.
Pain Worse on Inspiration: Pain on inspiration can be a sign of either local or generalised peritonitis – the pain associated with peritonitis can be aggravated by any type of movement, including inspiration or coughing.
Rebound Tenderness: This is a clinical sign where pain is elicited upon removal of pressure from the abdomen, rather than on application of pressure. It is indicative of localised or generalised peritonitis.
Constant Abdominal Pain: This can have various causes, including bowel obstruction, necrotising enterocolitis, colonic infection, peritoneal dialysis, post-laparotomy or laparoscopy, and many more.
Understanding these signs and symptoms can help in the early detection and treatment of peritonitis. If you experience any of these symptoms, it is important to seek medical attention immediately.

Question 2
Incorrect
-
A 45-year-old man is admitted to Emergency Department (ED) with haematemesis of bright red blood. He is an alcoholic. He has cool extremities, guarding over the epigastric region, he is ascitic, and has eight spider naevi on his neck and chest. An ABCD management is begun along with fluid resuscitation.
Given the likely diagnosis, what medication is it most important to start?Your Answer: Antibiotics iv
Correct Answer: Terlipressin
Explanation:In cases of suspected variceal bleeding, the priority medication to administer is terlipressin. This drug causes constriction of the mesenteric arterial circulation, leading to a decrease in portal venous inflow and subsequent reduction in portal pressure, which can help to control bleeding. Band ligation should be performed after administering terlipressin, and if bleeding persists, a transjugular intrahepatic portosystemic shunt (TIPS) may be necessary. Antibiotics may also be given prophylactically, but they do not directly affect bleeding. Clopidogrel should be avoided as it can worsen bleeding, while omeprazole may be used according to hospital guidelines. Tranexamic acid is not indicated for oesophageal variceal bleeds.

Which of the following is the most likely diagnosis?Your Answer: Insulinoma
Correct Answer: Somatostatinoma
Explanation:Overview of APUD Cell Tumours and their Presentations
APUD cell tumours are rare and can affect various organs in the body. Some of the most common types include somatostatinoma, glucagonoma, insulinoma, gastrinoma, and VIPoma. These tumours can present with a range of symptoms, such as gallstones, weight loss, diarrhoea, diabetes mellitus, necrolytic migratory erythema, sweating, light-headedness, and peptic ulceration. Diagnosis can be challenging, but imaging techniques and hormone measurements can aid in identifying the tumour. Treatment options include surgery, chemotherapy, and hormone therapy. It is important to note that some of these tumours may be associated with genetic syndromes, such as MEN 1 syndrome.

A 61-year-old man has been admitted to a General Surgical Ward, following an endoscopic retrograde cholangiopancreatography (ERCP) for acute cholangitis. The procedure took place approximately two hours ago and went well, without complications. The patient is now complaining of central abdominal pain, radiating to the back.
His observations are normal. Examination is significant for central abdominal pain. His blood tests are significant for an amylase level of 814 u/l. His pre-ERCP amylase level was 89 u/l.
What is the most likely diagnosis?Your Answer: Acute pancreatitis
Explanation:Complications of ERCP: Post-ERCP Pancreatitis, Papillary Stenosis, Anaphylaxis, Duodenal Pneumostasis, and Oesophageal Perforation
Endoscopic retrograde cholangiopancreatography (ERCP) is a diagnostic and therapeutic procedure used to examine the bile ducts and pancreatic ducts. However, like any medical procedure, ERCP is not without risks. Here are some of the possible complications of ERCP:
Post-ERCP Pancreatitis: This is a common complication of ERCP, with an incidence of approximately 2-3%. It is characterized by abdominal pain that radiates to the back and a significant elevation in amylase levels. Treatment involves analgesia, hydration, and bowel rest.
Papillary Stenosis: This is a late complication of ERCP that occurs in approximately 2-4% of patients. It is treated with endoscopic management, such as stenting or balloon dilation.
Anaphylaxis: Although rare, anaphylactic reactions to contrast agents used during ERCP can occur. Symptoms include respiratory compromise and hypotension, and treatment involves adrenaline and airway support.
Duodenal Pneumostasis: This complication refers to a collection of air in the duodenal wall and is typically recognized during the procedure. The procedure should be stopped to avoid bowel perforation.
Oesophageal Perforation: This is a rare complication of ERCP that typically presents with chest pain, mediastinitis, and cardiovascular instability.
In conclusion, while ERCP is a useful diagnostic and therapeutic tool, it is important to be aware of the potential complications and to take appropriate measures to prevent and manage them.

What statement is true about infants who have gastroenteritis?
Your Answer: Usually have blood in their stools
Correct Answer: Should be admitted to hospital if they are unable to tolerate fluid orally
Explanation:Management of Gastroenteritis in Children
Gastroenteritis is a common illness in children that is usually caused by a viral infection. Antibiotics are not necessary in most cases as they are only effective against bacterial infections. Changing formula feeds is also not recommended as it may cause further digestive problems. However, if the child is unable to tolerate oral fluids, intravenous fluid therapy may be necessary to prevent dehydration.
Lactose intolerance is a common occurrence in children with gastroenteritis, but it is not inevitable. It is important to monitor the child’s symptoms and adjust their diet accordingly. Barium meals are not useful in the investigation of gastroenteritis as they are more commonly used to diagnose structural abnormalities in the digestive system.
In summary, the management of gastroenteritis in children involves providing supportive care such as oral rehydration therapy and monitoring for signs of dehydration. Antibiotics are not necessary unless there is a bacterial infection present. It is important to be aware of the possibility of lactose intolerance and adjust the child’s diet accordingly. Barium meals are not useful in the investigation of gastroenteritis.

As the F1 on call, you have been summoned to attend to a 36-year-old man who has been admitted with decompensated alcoholic liver disease. Upon examination, you observe widespread stigmata of chronic liver disease with tense ascites and mild peripheral oedema. There is no indication of encephalopathy, and all vital signs are within acceptable limits. The most recent blood tests reveal a haemoglobin level of 115 g/L (120-140), a white cell count of 5.6 ×109/L (4.0-11.0), and a platelet count of 79 ×109/L (150-400), among other things. The patient is experiencing abdominal pain. What is the safest analgesic agent to prescribe to this patient?
Your Answer: Paracetamol
Explanation:Special Considerations for Drug Prescribing in Patients with Advanced Liver Disease
Patients with advanced liver disease require special attention when it comes to drug prescribing due to the altered pathophysiology of the liver. The liver’s poor synthetic function can lead to impaired enzyme formation, reducing the ability to excrete hepatically metabolized drugs. Concurrent use of enzyme-inducing drugs can lead to the accumulation of toxic metabolites. Additionally, reduced synthesis of blood clotting factors by a damaged liver means that these patients can often auto-anticoagulate, and drugs that interfere with the clotting process are best avoided.
Aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and diclofenac should be avoided in liver disease patients. These drugs promote gastric irritation, increasing the likelihood of gastrointestinal bleeding, which is significantly increased if there are upper gastrointestinal varices present. NSAIDs can also promote fluid retention and worsen peripheral edema and ascites. Morphine sulfate and tramadol hydrochloride are both opioid analgesics that should only be considered in patients with advanced liver disease by hepatologists as they can promote the development of hepatic encephalopathy. Paracetamol is considered the safest analgesic to use in these patients, even in severe liver disease, as long as the doses are halved.
In conclusion, patients with advanced liver disease require special care in drug prescribing due to the altered pathophysiology of the liver. It is important to avoid drugs that interfere with the clotting process, promote gastric irritation, and worsen peripheral edema and ascites. Opioid analgesics should only be considered by hepatologists, and paracetamol is considered the safest analgesic to use in these patients.

A 40-year-old woman has been visiting her doctor frequently over the past year due to recurring episodes of abdominal cramps and diarrhoea. She is concerned about the possibility of bowel cancer, as her father passed away from it at the age of 86. She has no other relevant family history. She also mentions that she needs a refill for her salbutamol inhaler, which she takes for her recently diagnosed asthma. Additionally, she has noticed an increase in hot flashes and wonders if she is experiencing early menopause. She has lost some weight, which she attributes to her healthy diet. What is the most probable diagnosis?
Your Answer: Irritable bowel syndrome
Correct Answer: Gastrointestinal neuroendocrine tumour (NET)
Explanation:Diagnosis and Management of Gastrointestinal Neuroendocrine Tumour (NET)
A patient presenting with symptoms of diarrhoea, wheezing, and flushing may have a gastrointestinal neuroendocrine tumour (NET), also known as carcinoid syndrome. It is important to consider NET in the differential diagnosis, even in relatively young patients, as the average delay in diagnosis is 2-3 years.
Appropriate investigations include routine blood tests, gut hormone measurement, 24-hour urinary 5-hydroxyindoleacetic acid (5-HIAA) measurement, cross-sectional imaging, and gastrointestinal endoscopy. Management options include somatostatin analogues, peptide receptor radiotargeted therapy (PRRT), and molecularly targeted treatments such as sunitinib or everolimus.
Health/illness-related anxiety, or hypochondriasis, should be a diagnosis of exclusion, and physical causes should be addressed first. Irritable bowel syndrome may cause similar symptoms, but without hot flashes or asthma. Colorectal or gastric adenocarcinoma may also be considered, but the symptoms are more consistent with a NET.
Most gastrointestinal NETs are low grade, and even in metastatic disease, the median overall survival is around 10 years. Early diagnosis and appropriate management can improve outcomes for patients with NET.

A 50-year-old man was admitted for an endoscopic retrograde cholangio-pancreatography (ERCP) due to biliary colic. He had an uneventful procedure, but was re-admitted the same night with severe abdominal pain. He is tachycardic, short of breath, and has a pleural effusion on his chest X-ray (CXR). His blood tests show C-reactive protein (CRP) 200 mg/litre, white cell count (WCC) 16 × 109/litre, creatine 150 µmol/litre, urea 8 mmol/litre, phosphate 1.1 mmol/litre, calcium 0.7 mmol/litre.
What is his most likely diagnosis?Your Answer:
Correct Answer: Pancreatitis
Explanation:Diagnosing and Managing Complications of ERCP: A Case Study
A patient presents with abdominal pain, hypocalcaemia, and a pleural effusion several hours after undergoing an ERCP. The most likely diagnosis is pancreatitis, a known complication of the procedure. Immediate management includes confirming the diagnosis and severity of pancreatitis, aggressive intravenous fluid resuscitation, oxygen, and adequate analgesia. Severe cases may require transfer to intensive care. Intestinal and biliary perforation are unlikely causes, as they would have presented with immediate post-operative pain. A reaction to contrast would have occurred during the procedure. Another possible complication is ascending cholangitis, which presents with fever, jaundice, and abdominal pain, but is unlikely to cause hypocalcaemia or a pleural effusion. It is important to promptly diagnose and manage complications of ERCP to prevent severe complications and improve patient outcomes.

A 16-year-old previously healthy woman presents with a 10-month history of persistent non-bloody diarrhoea and central abdominal pain. She also gives a history of unintentional weight loss. The patient is not yet menstruating. On examination, she has slight conjunctival pallor. Blood tests reveal a macrocytic anaemia.
What is the likeliest diagnosis?Your Answer:
Correct Answer: Coeliac disease
Explanation:Coeliac disease is a condition where the lining of the small intestine is abnormal and improves when gluten is removed from the diet. It is caused by an immune response to a component of gluten called α-gliadin peptide. Symptoms can occur at any age but are most common in infancy and in adults in their 40s. Symptoms include abdominal pain, bloating, diarrhea, delayed puberty, and anemia. Blood tests are used to diagnose the disease, and a biopsy of the small intestine can confirm the diagnosis. Treatment involves avoiding gluten in the diet. Crohn’s disease and ulcerative colitis have different symptoms, while irritable bowel syndrome and carcinoid syndrome are unlikely in this case.

A 28-year-old woman with Crohn's disease (CD) visits her primary care physician for a regular follow-up. During the examination, the doctor observes clubbing, hepatomegaly, and episcleritis, which are known signs linked with CD. What other non-intestinal symptom is commonly associated with CD?
Your Answer:
Correct Answer: Pyoderma gangrenosum
Explanation:Extra-Intestinal Manifestations and Skin Conditions Associated with Inflammatory Bowel Disease
Inflammatory bowel disease (IBD), including Crohn’s disease (CD) and ulcerative colitis (UC), can present with extra-intestinal manifestations, with some features being more prevalent in one than the other. Joint complications are the most common, but other manifestations include eye inflammation, joint pain and stiffness, and liver and biliary tree issues. Additionally, CD can present with skin conditions such as pyoderma gangrenosum, while UC is associated with primary sclerosing cholangitis and cholangiocarcinoma.
Other skin conditions, such as necrobiosis lipoidica and palmar erythema, are not associated with IBD. Erythema multiforme is a drug-related skin rash, while lichen planus is a skin rash of unknown cause that is not associated with IBD. It is important for healthcare providers to be aware of these extra-intestinal manifestations and skin conditions when evaluating patients with IBD.
