Question 1
Correct
-
A 20-year old man presents to the Surgical Assessment Unit complaining of sudden onset abdominal pain. What physical examination finding is most indicative of a possible diagnosis of appendicitis?
Your Answer: Tenderness over McBurney’s point
Explanation:Common Abdominal Exam Findings and Their Significance
Abdominal exams are an important part of diagnosing various medical conditions. Here are some common findings and their significance:
Tenderness over McBurney’s point: This is a sign of possible appendicitis. McBurney’s point is located a third of the way from the right anterior superior iliac spine to the umbilicus.
Grey–Turner’s sign: Flank bruising is a sign of retroperitoneal hemorrhage, which is commonly associated with acute pancreatitis.
Murphy’s sign: This suggests cholecystitis. The examiner places their hand below the right costal margin and the tender gallbladder moves inferiorly on inhalation, causing the patient to catch their breath.
Tinkling bowel sounds: High-pitched, ‘tinkling’ bowel sounds are typically associated with mechanical bowel obstruction.
Absent bowel sounds: This is suggestive of paralytic ileus, which most commonly occurs after abdominal surgery.

A 35-year-old woman visits her General Practitioner (GP) complaining of diarrhoea that has lasted for 2 weeks. She mentions passing mucous and blood rectally and reports feeling generally unwell. During the examination, the GP observes aphthous ulceration in her mouth and suspects a diagnosis of ulcerative colitis (UC). The GP decides to refer the patient to a gastroenterology consultant.
What is the recommended first-line medication for patients with mild to moderate UC?Your Answer: Azathioprine
Correct Answer: Mesalazine
Explanation:Treatment Options for Ulcerative Colitis
Ulcerative colitis (UC) is a chronic inflammatory bowel disease that affects the rectum and may spread to the colon. The main symptom is bloody diarrhea, and the disease follows a relapsing and remitting course. The goal of UC management is to treat acute relapses, prevent relapses, and detect cancers early.
Mesalazine is an effective first-line treatment for mild to moderate UC, which involves enemas and oral medication. For moderately active cases, oral aminosalicylates, topical aminosalicylates, and corticosteroids are used. Azathioprine is an immunomodulator that is rarely used to induce remission but is used to keep patients in remission. Hydrocortisone is a systemic steroid used for severe cases. Infliximab is an anti-tumor necrosis factor biologic used for moderate to severe cases that are refractory to standard treatment. Methotrexate is an alternative immunomodulator for patients who cannot tolerate azathioprine. It is important to discuss adequate contraception with patients on methotrexate due to its teratogenicity.

A 45-year-old alcoholic presents to the Emergency Department with retrosternal chest pain, shortness of breath and pain on swallowing after a heavy drinking session the night before. He reports having vomited several times this morning, after which the pain started. He denies any blood in the vomit and has no melaena. On examination, he is febrile and tachypnoeic and has a heart rate of 110 bpm. A chest X-ray reveals a left-sided pneumothorax and air within the mediastinum.
Given the likely diagnosis, what is the most appropriate management to treat the underlying cause of his symptoms?Your Answer: Chest drain insertion
Correct Answer: Urgent surgery
Explanation:Management of Suspected Oesophageal Rupture
Suspected oesophageal rupture is a medical emergency that requires urgent intervention. This condition is more common in patients with a history of alcohol excess and can be associated with a triad of vomiting, chest pain, and subcutaneous emphysema. Symptoms include retrosternal chest/epigastric pain, tachypnoea, fever, pain on swallowing, and shock. A chest X-ray reveals gas within soft tissue spaces, pneumomediastinum, left pleural effusion, and left-sided pneumothorax. Without rapid treatment, the condition can be fatal.
Antibiotics are necessary to treat the infection that may result from oesophageal rupture. However, they will not address the underlying cause of the infection.
Chest drain insertion is not the correct management for pneumothorax secondary to oesophageal rupture. A chest drain would not resolve the underlying cause, and air would continue to enter the pleural cavity via the oesophagus.
Proton pump inhibitors (PPIs) are not appropriate for suspected oesophageal rupture. PPIs would be the correct management for a suspected perforated ulcer. However, the history of acute-onset pain following vomiting is more in keeping with oesophageal rupture.
Urgent endoscopy is not appropriate for suspected oesophageal rupture. Endoscopy risks further oesophageal perforation, and there is no report of haematemesis or melaena, making this a less likely cause of the patient’s symptoms.

A 65-year-old man (with known metastatic pancreatic cancer) presented with severe obstructive jaundice and signs of hepatic encephalopathy. He was treated with a biliary stent (percutaneous transhepatic cholangiography (PTC)) and discharged when his jaundice, confusion and pruritus had started to improve. He re-presented shortly after discharge with rigors, pyrexia and feeling generally unwell. His blood cultures showed Gram-negative rods.
What is the most likely cause of his current presentation?Your Answer: Ascending cholangitis
Explanation:Possible Causes of Fever and Rigors in a Patient with a Biliary Stent
Introduction:
A patient with a biliary stent inserted via endoscopic retrograde cholangiopancreatography (ERCP) presents with fever and rigors. This article discusses the possible causes of these symptoms.Possible Causes:
1. Ascending Cholangitis: This is the most likely option as the patient’s biliary stent and the ERCP procedure are both well-known risk factors for acute cholangitis. The obstruction caused by the stent can lead to recurrent biliary sepsis, which can be life-threatening and requires prompt treatment with broad-spectrum antibiotics and IV fluids.2. Lower Respiratory Tract Infection: Sedation and endoscopy increase the risk of pulmonary infection, particularly aspiration. However, the biliary stent itself is the biggest risk factor, and the patient’s symptoms point towards ascending cholangitis.
3. Hepatitis: This is an unlikely cause of fever and rigors as there are no risk factors for common causes of acute hepatitis, and Gram-negative rods are not a common cause of hepatitis.
4. Metastatic Pancreatic Cancer: While this condition can increase the risk of infection due to immunocompromised, it does not fully explain the patient’s presentation as it would not cause frank fever and rigors.
5. Pyelonephritis: This bacterial infection of the kidney can cause pyrexia, rigors, and malaise, with Gram-negative rods, especially E. coli, as common causes. However, the recent biliary stent insertion puts this patient at high risk of ascending cholangitis.
Conclusion:
In conclusion, the most likely cause of fever and rigors in a patient with a biliary stent is ascending cholangitis. However, other possible causes should also be considered and ruled out through appropriate diagnostic tests. -

A 55-year-old man presents to the general practitioner (GP) with a 6-month history of increasing difficulty with swallowing solid foods. He does not have any problems with swallowing liquids. He has always been overweight but has lost 5 kg in the past few months. He attributes this eating a little less due to his swallowing difficulties. He has a past history of long-term heartburn and indigestion, which he has been self-treating with over-the-counter antacids. The GP is concerned that the patient may have oesophageal cancer.
Which one of the following statements with regard to oesophageal cancer is correct?Your Answer: Barrett’s oesophagus is a pre-malignant condition that may lead to squamous carcinoma
Correct Answer: Achalasia predisposes to squamous carcinoma of the oesophagus
Explanation:Understanding Oesophageal Carcinoma: Risk Factors, Diagnosis, and Prognosis
Oesophageal carcinoma is a type of cancer that affects the oesophagus, the muscular tube that connects the throat to the stomach. In this article, we will discuss the risk factors, diagnosis, and prognosis of oesophageal carcinoma.
Risk Factors
Achalasia, a condition that affects the ability of the oesophagus to move food down to the stomach, and alcohol consumption are associated with squamous carcinoma, which most commonly affects the upper and middle oesophagus. Barrett’s oesophagus, a pre-malignant condition that may lead to squamous carcinoma, and gastro-oesophageal reflux disease (GORD) predispose to adenocarcinoma, which occurs in the lower oesophagus.
Diagnosis
Barrett’s oesophagus is a recognised pre-malignant condition that requires acid-lowering therapy and frequent follow-up. Ablative and excisional therapies are available. Most cases are amenable to curative surgery at diagnosis. Dysphagia, or difficulty swallowing, is an early manifestation of the disease and is typically experienced with solid foods.
Prognosis
Prognosis depends on the stage and grade at diagnosis, but unfortunately, the disease frequently presents once the cancer has spread. Therefore, early detection and treatment are crucial for improving outcomes.
Conclusion
Oesophageal carcinoma is a serious condition that requires prompt diagnosis and treatment. Understanding the risk factors, diagnosis, and prognosis can help individuals take steps to reduce their risk and seek medical attention if symptoms arise.

A 30-year-old patient presents with complaints of recurrent bloody diarrhoea and symptoms of iritis. On examination, there is a painful nodular erythematosus eruption on the shin and anal tags are observed. What diagnostic test would you recommend to confirm the diagnosis?
Your Answer:
Correct Answer: Colonoscopy
Explanation:Inflammatory Bowel Disease with Crohn’s Disease Suggestion
The patient’s symptoms and physical examination suggest inflammatory bowel disease, with anal skin tags indicating a possible diagnosis of Crohn’s disease. Other symptoms consistent with this diagnosis include iritis and a skin rash that may be erythema nodosum. To confirm the diagnosis, a colonoscopy with biopsies would be the initial investigation. While serum ACE levels can aid in diagnosis, they are often elevated in conditions other than sarcoidosis.
Overall, the patient’s symptoms and physical examination point towards inflammatory bowel disease, with Crohn’s disease as a possible subtype. Further testing is necessary to confirm the diagnosis and rule out other conditions.

A 26-year old woman has been asked to come in for a consultation at her GP's office after her blood test results showed an elevated level of anti-tissue transglutaminase antibody. What condition is linked to this antibody?
Your Answer:
Correct Answer: Coeliac disease
Explanation:Autoimmune Diseases: Causes and Symptoms
Autoimmune diseases are conditions where the body’s immune system attacks its own tissues and organs. Here are some examples of autoimmune diseases and their causes and symptoms:
Coeliac Disease
Coeliac disease is caused by an autoimmune reaction to gluten, a protein found in wheat. Symptoms include chronic diarrhoea, weight loss, and fatigue.Graves’ Disease
This autoimmune disease affects the thyroid gland, resulting in hyperthyroidism. It is associated with anti-thyroid-stimulating hormone (TSH) receptor antibodies.Pemphigus Vulgaris
This rare autoimmune disease causes blistering of the skin and mucosal surfaces due to autoantibodies against desmoglein.Systemic Lupus Erythematosus
This multisystem autoimmune disease is associated with a wide range of autoantibodies, including anti-nuclear antibody (ANA) and anti-double-stranded (ds) DNA. Symptoms can include joint pain, fatigue, and skin rashes.Type 1 Diabetes Mellitus
This autoimmune disease results in the destruction of islet cells in the pancreas. Islet cell autoantibodies and antibodies to insulin have been described as causes. Symptoms include increased thirst and urination, weight loss, and fatigue.In summary, autoimmune diseases can affect various organs and tissues in the body, and their symptoms can range from mild to severe. Understanding their causes and symptoms is crucial for early diagnosis and effective treatment.

A 23-year-old woman developed sudden-onset, severe epigastric pain 12 hours ago. She subsequently began having episodes of nausea and vomiting, especially after trying to eat or drink. The pain now feels more generalised, and even slight movement makes it worse. She has diminished bowel sounds and exquisite tenderness in the mid-epigastrium with rebound tenderness and board-like rigidity. Her pulse is 110 bpm and blood pressure 130/75. She reports taking ibuprofen for dysmenorrhoea. She had last taken ibuprofen the day before the pain began.
What is the most likely diagnosis?Your Answer:
Correct Answer: Perforated peptic ulcer
Explanation:Differential Diagnosis for Abdominal Pain: Perforated Peptic Ulcer
Abdominal pain can have various causes, and it is important to consider the differential diagnosis to determine the appropriate treatment. In this case, the patient’s use of non-steroidal anti-inflammatory drugs (NSAIDs) suggests a possible perforated peptic ulcer as the cause of her symptoms.
Perforated peptic ulcer is a serious complication of peptic ulcer disease that can result from the use of NSAIDs. The patient’s symptoms, including increasing generalised abdominal pain that is worse on moving, rebound tenderness, and board-like rigidity, are classic signs of generalised peritonitis. These symptoms suggest urgent surgical review and definitive surgical management.
Other possible causes of abdominal pain, such as acute gastritis, acute pancreatitis, appendicitis, and cholecystitis, have been considered but are less likely based on the patient’s symptoms. It is important to consider the differential diagnosis carefully to ensure appropriate treatment and avoid potential complications.

A middle-aged woman has presented to her GP with bowel symptoms, specifically wind and bloating. After conducting several tests, the GP has diagnosed her with irritable bowel syndrome (IBS).
What is an appropriate dietary recommendation to provide to this middle-aged woman?Your Answer:
Correct Answer: Restrict caffeinated and fizzy drinks
Explanation:Managing IBS through dietary changes
Irritable bowel syndrome (IBS) can be managed through dietary changes. It is important to restrict caffeinated and fizzy drinks as they can aggravate IBS symptoms. Increasing bran intake should be avoided, while reducing oat intake can help alleviate symptoms. Fresh fruit intake should be limited to no more than three portions a day. Eating small, frequent meals and taking time over eating is recommended. It may also be helpful to increase sorbitol content, found in sugar-free drinks, but only if diarrhoea is not a symptom. By making these dietary changes, individuals with IBS can better manage their symptoms and improve their quality of life.

A 35-year-old woman with known alcohol dependence is admitted to the Emergency Department following a 32-hour history of worsening confusion. She complains of excessive sweating and feeling hot; she is also distressed as she says that ants are crawling on her body – although nothing is visible on her skin. She states that over the last few days she has completely stopped drinking alcohol in an attempt to become sober.
On examination she is clearly agitated, with a coarse tremor. Her temperature is 38.2°C, blood pressure is 134/76 mmHg and pulse is 87 beats per minute. She has no focal neurological deficit. A full blood count and urinalysis is taken which reveals the following:
Full blood count:
Investigation Result Normal value
Haemoglobin 144 g/l 135–175 g/l
Mean corpuscular volume (MCV) 105 fl 76–98 fl
White cell count (WCC) 6.8 × 109/l 4–11 × 109/l
Platelets 220 × 109/l 150–400 × 109/l
There are no abnormalities detected on urine and electrolytes (U&Es) and liver function tests (LFTs).
Urinalysis:
Investigations Results
Leukocytes Negative
Nitrites Negative
Protein Negative
Blood Negative
Glucose Negative
Which of the following is the most likely diagnosis?Your Answer:
Correct Answer: Delirium tremens
Explanation:Differential Diagnosis for a Patient with Alcohol Withdrawal Symptoms
Delirium Tremens, Korsakoff’s Psychosis, Wernicke’s Encephalopathy, Hepatic Encephalopathy, and Focal Brain Infection: Differential Diagnosis for a Patient with Alcohol Withdrawal Symptoms
A patient presents with agitation, hyperthermia, and visual hallucinations after acute cessation of alcohol. What could be the possible diagnoses?
Delirium tremens is the most likely diagnosis, given the severity of symptoms and timing of onset. It requires intensive care management, and oral lorazepam is recommended as first-line therapy according to NICE guidelines.
Korsakoff’s psychosis, caused by chronic vitamin B1 deficiency, is unlikely to have caused the patient’s symptoms, but the patient is susceptible to developing it due to alcohol dependence and associated malnutrition. Treatment with thiamine is necessary to prevent this syndrome from arising.
Wernicke’s encephalopathy, also caused by thiamine deficiency, presents with ataxia, ophthalmoplegia, and confusion. As the patient has a normal neurological examination, this diagnosis is unlikely to have caused the symptoms. However, regular thiamine treatment is still necessary to prevent it from developing.
Hepatic encephalopathy, a delirium secondary to hepatic insufficiency, is unlikely as the patient has no jaundice, abnormal LFTs, or hemodynamic instability.
Focal brain infection is also unlikely as there is no evidence of meningitis or encephalitis, and the full blood count and urinalysis provide reassuring results. The high MCV is likely due to alcohol-induced macrocytosis. Although delirium secondary to infection is an important diagnosis to consider, delirium tremens is a more likely diagnosis in this case.
