    Correct

    • A 65-year-old woman visits her GP complaining of a lump in her groin area that she noticed last week. The lump is painless. During the examination, a soft, non-tender mass is palpable on her left inguinal area, medial and superior to the pubic tubercle. The lump disappears when she lies down, but when you try to reduce it and press on the mid-point of the inguinal ligament, it still protrudes if the patient stands up. The patient has no medical history and is not taking any medication. What is the most likely diagnosis?

      Your Answer: Direct inguinal hernia

      Explanation:

      The hernia in question is a direct inguinal hernia, which is located superior and medial to the pubic tubercle. Direct inguinal hernias enter the inguinal canal through the posterior wall, while indirect inguinal hernias enter via the deep inguinal ring. To differentiate between the two, one can try to reduce the hernia and press on the deep inguinal ring. If the hernia stops protruding, it is an indirect hernia, but if it continues to protrude, it is a direct hernia. Femoral hernias are found below and lateral to the pubic tubercle and are more common in women, while obturator hernias pass through the obturator foramen and typically present with bowel obstruction. The patient in this case does not have any symptoms of obstruction. It should be noted that the type of hernia can only be confirmed during surgery.

      Understanding Inguinal Hernias

      Inguinal hernias are the most common type of abdominal wall hernias, with 75% of cases falling under this category. They are more prevalent in men, with a 25% lifetime risk of developing one. The main feature of an inguinal hernia is a lump in the groin area, which is located superior and medial to the pubic tubercle. This lump disappears when pressure is applied or when the patient lies down. Discomfort and aching are common symptoms, which can worsen with activity, but severe pain is rare. Strangulation, a serious complication, is uncommon.

      The clinical management of inguinal hernias involves treating medically fit patients, even if they are asymptomatic. A hernia truss may be an option for patients who are not fit for surgery, but it has little role in other patients. Mesh repair is the preferred method of treatment, as it is associated with the lowest recurrence rate. Unilateral hernias are generally repaired with an open approach, while bilateral and recurrent hernias are repaired laparoscopically. Patients can return to non-manual work after 2-3 weeks following an open repair and after 1-2 weeks following laparoscopic repair, according to the Department for Work and Pensions.

      Complications of inguinal hernias include early bruising and wound infection, as well as late chronic pain and recurrence. While traditional textbooks describe the anatomical differences between indirect and direct hernias, this is not relevant to clinical management. Overall, understanding the features, management, and complications of inguinal hernias is crucial for proper diagnosis and treatment.

    Incorrect

    • A 50-year-old woman is scheduled for an elective hysterectomy tomorrow. What instructions should be given regarding her oral intake before the surgery?

      Your Answer: Food/solids > 12 hours beforehand and clear fluids > 2 hours beforehand

      Correct Answer: Food/solids > 6 hours beforehand and clear fluids > 2 hours beforehand

      Explanation:

      To ensure safe elective surgery, it is recommended that both adults and children drink clear fluids up to 2 hours before the procedure, but avoid consuming solid food for 6 hours prior. These guidelines also apply to pregnant women not in labor and patients with diabetes. Breast milk is safe up to 4 hours before surgery, while other types of milk should be avoided for 6 hours.

      In the case of emergency surgery for an adult patient who has not fasted, the Rapid Sequence Induction (RSI) technique can be used to minimize the risk of gastro-oesophageal reflux. This involves optimal preoxygenation, the use of an induction agent and suxamethonium, and the application of cricoid force at the onset of unconsciousness. However, as there has been no preoperative airway assessment, anaesthetists must be prepared for potential difficulties with laryngoscopy and intubation.

      Preparation for surgery varies depending on whether the patient is undergoing an elective or emergency procedure. For elective cases, it is important to address any medical issues beforehand through a pre-admission clinic. Blood tests, urine analysis, and other diagnostic tests may be necessary depending on the proposed procedure and patient fitness. Risk factors for deep vein thrombosis should also be assessed, and a plan for thromboprophylaxis formulated. Patients are advised to fast from non-clear liquids and food for at least 6 hours before surgery, and those with diabetes require special management to avoid potential complications. Emergency cases require stabilization and resuscitation as needed, and antibiotics may be necessary. Special preparation may also be required for certain procedures, such as vocal cord checks for thyroid surgery or bowel preparation for colorectal cases.

    Incorrect

    • A 45-year-old man comes to you with a chronic inguinal hernia. During the examination, you notice a small, direct inguinal hernia. He asks about the likelihood of strangulation if he chooses not to have surgery within the next year. What is the estimated risk of strangulation over the next 12 months?

      Your Answer: 15%

      Correct Answer:

      Explanation:

      Indirect hernias are more likely to cause bowel obstruction, which can be life-threatening if not treated promptly. Elective repair of hernias is generally safe, but emergency repair carries a higher risk of mortality, especially in older patients.

    Incorrect

    • A 70-year-old male with diabetes type 2 is scheduled for an appendectomy. He is not on insulin-based medications.

      What is the appropriate management for this patient?

      Your Answer: This patient should be recommenced on oral diabetes medication 48 hours after they commence eating postoperatively

      Correct Answer: This patient should be first on the list

      Explanation:

      To avoid complications arising from inadequate blood sugar management, it is recommended that patients with diabetes be given priority on the surgical schedule. Those with inadequate control or who are using insulin will require a sliding scale.

      Preparation for surgery varies depending on whether the patient is undergoing an elective or emergency procedure. For elective cases, it is important to address any medical issues beforehand through a pre-admission clinic. Blood tests, urine analysis, and other diagnostic tests may be necessary depending on the proposed procedure and patient fitness.

    Incorrect

    • As you approach the bedside of an elderly overweight woman, you notice that she appears to be quite drowsy. Upon calling out her name, you hear a grunting noise and quickly call for the nurse's assistance. The patient's oxygen saturations are at 82% on air.

      What would be the immediate next step in managing this patient?

      Your Answer: 15 L high flow oxygen

      Correct Answer: Head tilt, chin lift, jaw thrust

      Explanation:

      Three simple manoeuvres, namely head tilt, chin lift, and jaw thrust, can effectively relieve airway obstruction caused by poor pharyngeal muscle tone. This is a common scenario where a patient’s airway is obstructed due to drowsiness, resulting in reduced muscle tone in the pharynx. By performing the head tilt, chin lift, and jaw thrust manoeuvre, the airway can be opened, allowing for the return of airflow.

      Endotracheal intubation is the only method of securing the airway, as all other airway devices are supraglottic. It is not the first-line treatment and is typically performed by a trained professional, such as an anaesthetist, when controlled and secured ventilatory support is required, such as during surgeries or cardiac arrest.

      Therefore, the correct answer is head tilt, chin lift, and jaw thrust, as it effectively opens the airway. The laryngeal mask airway is a supraglottic airway device that is only used by trained professionals when tracheal intubation is difficult and a more definitive airway is required. It is not the first-line treatment. The nasopharyngeal airway is a bridging airway adjunct used in semi-conscious patients and may be beneficial if the patient continues to desaturate despite performing the head tilt, chin lift, jaw thrust manoeuvre and providing high flow oxygen.

      Airway Management Devices and Techniques

      Airway management is a crucial aspect of medical care, especially in emergency situations. In addition to airway adjuncts, there are simple positional manoeuvres that can be used to open the airway, such as head tilt/chin lift and jaw thrust. There are also several devices that can be used for airway management, each with its own advantages and limitations.

      The oropharyngeal airway is easy to insert and use, making it ideal for short procedures. It is often used as a temporary measure until a more definitive airway can be established. The laryngeal mask is widely used and very easy to insert. It sits in the pharynx and aligns to cover the airway, but it does not provide good control against reflux of gastric contents. The tracheostomy reduces the work of breathing and may be useful in slow weaning, but it requires humidified air and may dry secretions. The endotracheal tube provides optimal control of the airway once the cuff is inflated and can be used for long or short-term ventilation, but errors in insertion may result in oesophageal intubation.

      It is important to note that paralysis is often required for some of these devices, and higher ventilation pressures can be used with the endotracheal tube. Capnography should be monitored to ensure proper placement and ventilation. Each device has its own unique benefits and drawbacks, and the choice of device will depend on the specific needs of the patient and the situation at hand.

    Correct

    • A 65-year-old woman with a T4N0M0 primary triple-negative breast carcinoma is attending a pre-operative breast oncology clinic. The oncologist recommends neo-adjuvant chemotherapy (NACT) as a beneficial course of treatment. What should the patient be informed of when considering whether to undergo NACT?

      Your Answer: NACT can downsize the primary tumour, meaning that breast conserving surgery can be performed instead of a mastectomy

      Explanation:

      One of the main reasons for considering neo-adjuvant chemotherapy in breast cancer treatment is to shrink the size of the tumor before surgery. This can potentially allow for breast conserving surgery instead of a mastectomy, which has several benefits. Firstly, it is a less invasive surgical procedure, reducing the risks associated with surgery. Additionally, it can lead to better cosmetic outcomes for the patient.

      It is important to note that both NACT and surgery have their own set of side effects, which cannot be compared with each other. However, there is an exciting new area of breast cancer research that focuses on immunomodulation. Some trials have shown that anti-tumor immunity can be induced following cryoablation/radiotherapy and administration of immunomodulating drugs. Unfortunately, NACT does not have this effect.

      One common side effect of NACT is nausea. The effect of NACT on overall survival rates has been mixed, but its main indication remains downsizing of the primary tumor.

      Reference:
      Nice guideline NG101 (2018).

      Breast cancer management varies depending on the stage of the cancer, type of tumor, and patient’s medical history. Treatment options may include surgery, radiotherapy, hormone therapy, biological therapy, and chemotherapy. Surgery is typically the first option for most patients, except for elderly patients with metastatic disease who may benefit more from hormonal therapy. Prior to surgery, an axillary ultrasound is recommended for patients without palpable axillary lymphadenopathy, while those with clinically palpable lymphadenopathy require axillary node clearance. The type of surgery offered depends on various factors, such as tumor size, location, and type. Breast reconstruction is also an option for patients who have undergone a mastectomy.

      Radiotherapy is recommended after a wide-local excision to reduce the risk of recurrence, while mastectomy patients may receive radiotherapy for T3-T4 tumors or those with four or more positive axillary nodes. Hormonal therapy is offered if tumors are positive for hormone receptors, with tamoxifen being used in pre- and perimenopausal women and aromatase inhibitors like anastrozole in postmenopausal women. Tamoxifen may increase the risk of endometrial cancer, venous thromboembolism, and menopausal symptoms. Biological therapy, such as trastuzumab, is used for HER2-positive tumors but cannot be used in patients with a history of heart disorders. Chemotherapy may be used before or after surgery, depending on the stage of the tumor and the presence of axillary node disease. FEC-D is commonly used in the latter case.

    Incorrect

    • A 68-year-old man visits the oncology clinic after being diagnosed with ER-positive breast cancer. The doctor prescribes anastrozole, an aromatase inhibitor. What is a possible complication that may arise from this treatment?

      Your Answer: Endometrial cancer

      Correct Answer: Osteoporosis

      Explanation:

      Before and during treatment, it is important to monitor bone mineral density. AIs do not cause the side effects mentioned. Tamoxifen, a type of SERM, is used to treat ER positive breast cancer in both pre- and postmenopausal women. Adverse effects of tamoxifen include venous thromboembolism, endometrial cancer, cerebral ischaemia, and hypertriglyceridaemia.

      Anti-oestrogen drugs are used in the management of oestrogen receptor-positive breast cancer. Selective oEstrogen Receptor Modulators (SERM) such as Tamoxifen act as an oestrogen receptor antagonist and partial agonist. However, Tamoxifen can cause adverse effects such as menstrual disturbance, hot flashes, venous thromboembolism, and endometrial cancer. On the other hand, aromatase inhibitors like Anastrozole and Letrozole reduce peripheral oestrogen synthesis, which is important in postmenopausal women. Anastrozole is used for ER +ve breast cancer in this group. However, aromatase inhibitors can cause adverse effects such as osteoporosis, hot flashes, arthralgia, myalgia, and insomnia. NICE recommends a DEXA scan when initiating a patient on aromatase inhibitors for breast cancer.

What specific set of findings would prompt you to seek immediate senior evaluation?

      Your Answer: Ca 2.8 mmol/L, Urea 14 mmol/L, Albumin 31 g/L, Glucose 3.8 mmol/L

      Correct Answer: Ca 1.0 mmol/L, Urea 11 mmol/L, Albumin 30 g/L, Glucose 12 mmol/L

      Explanation:

      Hypercalcaemia can cause pancreatitis, but hypocalcaemia is an indicator of pancreatitis severity according to the PANCREAS scale, which includes factors such as age, blood oxygen levels, white blood cell count, calcium levels, renal function, enzyme levels, albumin levels, and blood sugar levels.

      Understanding Acute Pancreatitis

      Acute pancreatitis is a condition that is commonly caused by alcohol or gallstones. It occurs when the pancreatic enzymes start to digest the pancreatic tissue, leading to necrosis. The main symptom of acute pancreatitis is severe epigastric pain that may radiate through to the back. Vomiting is also common, and examination may reveal epigastric tenderness, ileus, and low-grade fever. In rare cases, periumbilical discolouration (Cullen’s sign) and flank discolouration (Grey-Turner’s sign) may be present.

      To diagnose acute pancreatitis, doctors typically measure the levels of serum amylase and lipase in the blood. While amylase is raised in 75% of patients, it does not correlate with disease severity. Lipase, on the other hand, is more sensitive and specific than amylase and has a longer half-life. Imaging tests, such as ultrasound and contrast-enhanced CT, may also be used to assess the aetiology of the condition.

      Scoring systems, such as the Ranson score, Glasgow score, and APACHE II, are used to identify cases of severe pancreatitis that may require intensive care management. Factors that indicate severe pancreatitis include age over 55 years, hypocalcaemia, hyperglycaemia, hypoxia, neutrophilia, and elevated LDH and AST. It is important to note that the actual amylase level is not of prognostic value.

      In summary, acute pancreatitis is a condition that can cause severe pain and discomfort. It is typically caused by alcohol or gallstones and can be diagnosed through blood tests and imaging. Scoring systems are used to identify cases of severe pancreatitis that require intensive care management.

She is 84, has known ischaemic heart disease under medical management, and was in new atrial fibrillation (AF) pre-operatively. You find that she has two quadrant peritonitis and despite fluid resuscitation her blood pressure is becoming low. You start Noradrenaline. She is going to intensive care unit (ICU) postoperatively.
      Which scoring system is generally used in this context to predict outcome?

      Your Answer: APACHE

      Correct Answer: P-POSSUM

      Explanation:

      Scoring Systems Used in Critical Care: An Overview

      In critical care, various scoring systems are used to assess patient outcomes and predict mortality and morbidity. The most commonly used systems include POSSUM, P-POSSUM, APACHE, SOFA, SAPS, and TISS.

      POSSUM (Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity) is a scoring system that utilizes surgical data to predict outcomes in emergency abdominal surgery. P-POSSUM is a modification of POSSUM that is more accurate in predicting outcomes.

      APACHE (Acute Physiology and Chronic Health Evaluation) is an ICU scoring system that is based on physiology. SOFA (Sequential Organ Failure Assessment) and SAPS (Simplified Acute Physiology Score) are also ICU scoring systems that are based on physiology.

      TISS (Therapeutic Intervention Scoring System) is a scoring system that measures patient interventions in the ICU. It is used to measure ICU workload and cost, rather than patient outcome.

      In critical care, these scoring systems are essential tools for assessing patient outcomes and predicting mortality and morbidity. Each system has its own strengths and limitations, and healthcare professionals must choose the most appropriate system for each patient.

      Your Answer: Reduces the rate of HIV transmission

      Explanation:

      Understanding Circumcision

      Circumcision is a practice that has been carried out in various cultures for centuries. Today, it is mainly practiced by people of the Jewish and Islamic faith for religious or cultural reasons. However, it is important to note that circumcision for these reasons is not available on the NHS.

      The medical benefits of circumcision are still a topic of debate. However, some studies have shown that it can reduce the risk of penile cancer, urinary tract infections, and sexually transmitted infections, including HIV.

      There are also medical indications for circumcision, such as phimosis, recurrent balanitis, balanitis xerotica obliterans, and paraphimosis. It is crucial to rule out hypospadias before performing circumcision as the foreskin may be needed for surgical repair.

      Circumcision can be performed under local or general anesthesia. It is a personal decision that should be made after careful consideration of the potential benefits and risks.

    • A 26-year-old male comes in with a painless lump in his testicle. During the examination, the lump is found to be hard and irregular. What is the most suitable test to order?

      Your Answer: Testicular ultrasound scan

      Explanation:

      The initial investigation for a testicular mass is an ultrasound, which is also the recommended first-line test for suspected testicular cancer. While beta-hCG levels may be elevated in certain types of testicular cancer, it is not a sensitive enough test to be used as the primary investigation. A surgical biopsy is not necessary at this stage, and a CT scan would subject the patient to unnecessary radiation. A bone scan is typically used for staging certain cancers after diagnosis, but it is not a first-line investigation for cancer.

      Understanding Testicular Cancer

      Testicular cancer is a type of cancer that commonly affects men between the ages of 20 and 30. Germ-cell tumors are the most common type of testicular cancer, accounting for around 95% of cases. These tumors can be divided into seminomas and non-seminomas, which include embryonal, yolk sac, teratoma, and choriocarcinoma. Other types of testicular cancer include Leydig cell tumors and sarcomas. Risk factors for testicular cancer include infertility, cryptorchidism, family history, Klinefelter’s syndrome, and mumps orchitis.

      The most common symptom of testicular cancer is a painless lump, although some men may experience pain. Other symptoms may include hydrocele and gynaecomastia, which occurs due to an increased oestrogen:androgen ratio. Tumor markers such as hCG, AFP, and beta-hCG may be elevated in germ cell tumors. Ultrasound is the first-line diagnostic tool for testicular cancer.

      Treatment for testicular cancer depends on the type and stage of the tumor. Orchidectomy, chemotherapy, and radiotherapy may be used. Prognosis for testicular cancer is generally excellent, with a 5-year survival rate of around 95% for seminomas and 85% for teratomas if caught at Stage I. It is important for men to perform regular self-examinations and seek medical attention if they notice any changes or abnormalities in their testicles.

      Your Answer: 16 Ch foley urethral catheter

      Correct Answer: Suprapubic catheter

      Explanation:

      Due to the patient’s history, there is a potential for urethral injury, therefore, urethral catheterisation should not be performed.

      Lower Genitourinary Tract Trauma: Types of Injury and Management

      Lower genitourinary tract trauma can occur due to blunt trauma, with most bladder injuries associated with pelvic fractures. However, these injuries can easily be overlooked during trauma assessment. In fact, up to 10% of male pelvic fractures are associated with urethral or bladder injuries.

      Urethral injuries are mainly found in males and can be identified by blood at the meatus in 50% of cases. There are two types of urethral injury: bulbar rupture and membranous rupture. Bulbar rupture is the most common and is caused by straddle-type injuries, such as those from bicycles. The triad signs of urinary retention, perineal hematoma, and blood at the meatus are indicative of this type of injury. Membranous rupture, on the other hand, can be extra or intraperitoneal and is commonly due to pelvic fractures. Penile or perineal edema/hematoma and a displaced prostate upwards are also signs of this type of injury. An ascending urethrogram is the recommended investigation, and management involves surgical placement of a suprapubic catheter.

      External genitalia injuries, such as those to the penis and scrotum, can be caused by penetration, blunt trauma, continence- or sexual pleasure-enhancing devices, and mutilation.

      Bladder injuries can be intra or extraperitoneal and present with haematuria or suprapubic pain. A history of pelvic fracture and inability to void should always raise suspicion of bladder or urethral injury. Inability to retrieve all fluid used to irrigate the bladder through a Foley catheter is also indicative of bladder injury. An IVU or cystogram is the recommended investigation, and management involves laparotomy if intraperitoneal and conservative treatment if extraperitoneal.

      In summary, lower genitourinary tract trauma can have various types of injuries, and prompt diagnosis and management are crucial to prevent further complications.

      Liver Tumours: Types, Diagnosis, and Treatment

      Liver tumours can be classified as primary or metastatic. Primary liver tumours are relatively rare, with cholangiocarcinoma and hepatocellular carcinoma being the most common types. Hepatocellular carcinoma accounts for 75% of primary liver tumours and is often associated with chronic inflammatory activity, such as cirrhosis or chronic hepatitis B infection. Diagnosis is typically made through imaging modalities like CT or MRI, with elevated levels of a-fetoprotein being a common marker. Biopsy should be avoided as it can spread tumour cells. Treatment options include surgical resection, liver resection, transplantation, and tumour ablation. However, the poor overall survival rate of 15% at 5 years highlights the need for better treatment options.

      Cholangiocarcinoma is the second most common type of primary liver malignancy, with up to 80% of tumours arising in the extrahepatic biliary tree. Primary sclerosing cholangitis is a major risk factor, and patients typically present with jaundice. Diagnosis is made through liver function tests, imaging methods like CT or MRI, and elevated levels of tumour markers like CA 19-9, CEA, and CA 125. Surgical resection offers the best chance of cure, but local invasion of peri hilar tumours and lobar atrophy can often make it impossible. Palliation of jaundice is important, but metallic stents should be avoided in those considered for resection. The poor survival rate of approximately 5-10% 5 year survival highlights the need for better treatment options.

      In summary, liver tumours can be classified as primary or metastatic, with primary liver tumours being relatively rare. Hepatocellular carcinoma and cholangiocarcinoma are the most common types of primary liver tumours, with diagnosis typically made through imaging modalities and elevated tumour markers. Treatment options include surgical resection, liver resection, transplantation, and tumour ablation, but the poor overall survival rate highlights the need for better treatment options.

    Incorrect

    • A 20-year-old student falls from a 2nd-floor window. She is persistently hypotensive. A chest x-ray shows a widened mediastinum with depression of the left main bronchus and deviation of the trachea to the right. What is the most probable injury?

      Your Answer: Tension pneumothorax

      Correct Answer: Aortic rupture

      Explanation:

      The patient has suffered a deceleration injury and is experiencing ongoing low blood pressure due to a contained hematoma. This suggests that there may be a rupture in the aorta, although a widened mediastinum may not always be visible on a chest X-ray. To obtain a more accurate assessment of the injury, a CT angiogram is recommended. The fact that the patient has been experiencing persistent hypotension from an early stage is more indicative of a hematoma than a tension pneumothorax, which typically only causes low blood pressure as a final symptom before cardiac arrest.

      Thoracic Trauma: Common Conditions and Treatment

      Thoracic trauma can result in various conditions that require prompt medical attention. Tension pneumothorax, for instance, occurs when pressure builds up in the thorax due to a laceration to the lung parenchyma with a flap. This condition is often caused by mechanical ventilation in patients with pleural injury. Symptoms of tension pneumothorax overlap with cardiac tamponade, but hyper-resonant percussion note is more likely. Flail chest, on the other hand, occurs when the chest wall disconnects from the thoracic cage due to multiple rib fractures. This condition is associated with pulmonary contusion and abnormal chest motion.

      Pneumothorax is another common condition resulting from lung laceration with air leakage. Traumatic pneumothoraces should have a chest drain, and patients should never be mechanically ventilated until a chest drain is inserted. Haemothorax, which is most commonly due to laceration of the lung, intercostal vessel, or internal mammary artery, is treated with a large bore chest drain if it is large enough to appear on CXR. Surgical exploration is warranted if more than 1500 ml blood is drained immediately.

      Cardiac tamponade is characterized by elevated venous pressure, reduced arterial pressure, and reduced heart sounds. Pulsus paradoxus may also occur with as little as 100 ml blood. Pulmonary contusion is the most common potentially lethal chest injury, and arterial blood gases and pulse oximetry are important. Early intubation within an hour is necessary if significant hypoxia is present. Blunt cardiac injury usually occurs secondary to chest wall injury, and ECG may show features of myocardial infarction. Aorta disruption, diaphragm disruption, and mediastinal traversing wounds are other conditions that require prompt medical attention.

      What is the most probable diagnosis and what would be the best initial treatment?

      Your Answer: Reassurance

      Explanation:

      Duct ectasia does not require any specific treatment. However, lumpectomy may be used to treat breast masses if they meet certain criteria such as being small-sized and peripheral, and taking into account the patient’s preference. Mastectomy may be necessary for malignant breast masses if lumpectomy is not suitable. In young women with duct ectasia, microdochectomy may be performed if the condition is causing discomfort. It is also used to treat intraductal papilloma.

      Understanding Duct Ectasia

      Duct ectasia is a condition that affects the terminal breast ducts located within 3 cm of the nipple. It is a common condition that becomes more prevalent as women age. The condition is characterized by the dilation and shortening of the ducts, which can cause nipple retraction and creamy nipple discharge. It is important to note that duct ectasia can be mistaken for periductal mastitis, which is more common in younger women who smoke. Periductal mastitis typically presents with infections around the periareolar or subareolar areas and may recur.

      When dealing with troublesome nipple discharge, treatment options may include microdochectomy for younger patients or total duct excision for older patients.

    Correct

    • A 38-year-old man visits his GP complaining of urinary incontinence. He reports experiencing occasional leakage of urine when he does not intend to. He denies any correlation between the timing of symptoms and coughing/sneezing. The patient has a history of a fractured wrist 4 years ago and was treated for gonorrhoeae 7 months ago. What is the probable diagnosis for this man's symptoms?

      Your Answer: Urethral stricture

      Explanation:

      A man with a history of gonorrhoeae who is experiencing urinary incontinence may be suffering from a urinary stricture. This is because his symptoms and medical history suggest that this is the most likely cause. If the incontinence was due to stress, it would be triggered by coughing or sneezing, which is not the case here. Urge incontinence is also unlikely as it is characterized by a sudden need to urinate, rather than a small dribble. Mixed incontinence is not a possibility as there are no signs of either stress or urge incontinence. Functional incontinence is also not the cause as the patient’s urinary system is normal, and the incontinence is likely due to other factors such as mobility issues or pain.

      Understanding Urethral Stricture and Its Causes

      Urethral stricture is a condition that occurs when the urethra, the tube that carries urine from the bladder out of the body, becomes narrow or blocked. This can cause difficulty in urination, pain, and other complications. There are several causes of urethral stricture, including iatrogenic factors such as traumatic placement of indwelling urinary catheters, sexually transmitted infections, hypospadias, and lichen sclerosus.

      Iatrogenic causes refer to those that are caused by medical procedures or treatments, such as the insertion of a catheter. Sexually transmitted infections, on the other hand, can cause inflammation and scarring of the urethra, leading to stricture. Hypospadias is a congenital condition where the urethral opening is not at the tip of the penis, which can increase the risk of developing strictures. Lichen sclerosus is a skin condition that can affect the genital area and cause scarring, which can also lead to urethral stricture.

      It is important to identify the underlying cause of urethral stricture in order to determine the appropriate treatment. In some cases, surgery may be necessary to remove the blockage and widen the urethra. In other cases, medication or other non-invasive treatments may be effective. Regular check-ups with a healthcare provider can help prevent complications and ensure proper management of this condition.

    Correct

    • A 44-year-old man is recovering on the ward several weeks after being treated for acute pancreatitis caused by excessive alcohol consumption. Despite being clinically stable, he continues to experience pain in the epigastric region. Routine blood tests and an abdominal ultrasound scan are performed, revealing the following results:

      - Bilirubin: 28 µmol/l
      - Albumin: 38 g/l
      - ALT: 39 u/l
      - γGT: 68 u/l
      - CRP: 11.2 mg/l
      - Amylase: 541 u/l

      The abdominal ultrasound scan shows normal kidney and liver appearances, as well as a normal aortic diameter. However, a cystic lesion measuring 53 mm x 61 mm is present in the head of the pancreas. What is the most appropriate initial management strategy for this patient's pancreatic lesion?

      Your Answer: Conservative management

      Explanation:

      When a cystic lesion and elevated amylase levels are observed after pancreatitis, it is likely to be a pancreatic pseudocyst. In such cases, it is best to initially manage the condition conservatively, especially if the patient is stable and liver function is not significantly affected. Procedures such as radiological fine-needle aspiration should be avoided as they can increase the risk of infection and have a high morbidity and mortality rate. Active drainage is only necessary if there are signs of infection, mass effect on abdominal organs, or if the pseudocyst persists beyond 12 weeks. Even if the patient experiences symptoms, conservative management is often preferred as the risks of a procedure outweigh the benefits.

      Acute pancreatitis can lead to various complications, both locally and systemically. Local complications include peripancreatic fluid collections, which occur in about 25% of cases and may develop into pseudocysts or abscesses. Pseudocysts are walled by fibrous or granulation tissue and typically occur 4 weeks or more after an attack of acute pancreatitis. Pancreatic necrosis, which involves both the pancreatic parenchyma and surrounding fat, can also occur and is directly linked to the extent of necrosis. Pancreatic abscesses may result from infected pseudocysts and can be treated with drainage methods. Haemorrhage may also occur, particularly in cases of infected necrosis.

      Systemic complications of acute pancreatitis include acute respiratory distress syndrome, which has a high mortality rate of around 20%. Local complications such as peripancreatic fluid collections and pancreatic necrosis can also lead to systemic complications if left untreated. It is important to manage these complications appropriately, with conservative management being preferred for sterile necrosis and early necrosectomy being avoided unless necessary. Treatment options for local complications include endoscopic or surgical cystogastrostomy, aspiration, and drainage methods. Overall, prompt recognition and management of complications is crucial in improving outcomes for patients with acute pancreatitis.

    • A 5-year-old boy is scheduled for surgery to remove a sebaceous cyst on his neck. During examination, a sebaceous cystic swelling measuring 2 cm in diameter is found in the left anterior neck triangle near the midline, with a punctum on top. The surgeon makes an elliptical incision around the cyst and removes the skin with the central punctum. The cyst is then removed to a depth of 1 cm. You have been tasked with closing the skin wound. What is the best option?

      Your Answer: Monocryl

      Explanation:

      Choosing the Right Suture Material for Skin Closure

      When it comes to closing a skin defect, several factors need to be considered, including the location of the wound, required tensile strength, cosmesis, and ease of stitch removal, especially in children. Monocryl, a monofilament absorbable suture, is the best choice for achieving optimal cosmetic results. Nylon, another monofilament suture, is also a reasonable option, but Monocryl’s absorbable nature eliminates the need for stitch removal, making it more practical for children. Steri-strips may not provide enough strength to keep the wound closed, while staples are more likely to cause scarring. Silk, a multi-filament non-absorbable suture, is not ideal for achieving optimal cosmesis. Therefore, choosing the right suture material is crucial for achieving the best possible outcome in skin closure.

A cystoscopy reveals a high-grade papillary carcinoma, specifically a transitional cell carcinoma of the bladder. What occupational exposure is a known risk factor for this type of bladder cancer?

      Your Answer: Beryllium

      Correct Answer: Aniline dye

      Explanation:

      Risk Factors for Bladder Cancer

      Bladder cancer is a type of cancer that affects the bladder, and there are different types of bladder cancer. The most common type is urothelial (transitional cell) carcinoma, and the risk factors for this type of bladder cancer include smoking, exposure to aniline dyes, rubber manufacture, and cyclophosphamide. Smoking is the most important risk factor in western countries, with a hazard ratio of around 4. Exposure to aniline dyes, such as working in the printing and textile industry, can also increase the risk of bladder cancer. Rubber manufacture and cyclophosphamide are also risk factors for urothelial carcinoma.

      On the other hand, squamous cell carcinoma of the bladder has different risk factors. Schistosomiasis and smoking are the main risk factors for this type of bladder cancer. Schistosomiasis is a parasitic infection that can cause inflammation and damage to the bladder, which can increase the risk of developing squamous cell carcinoma. Smoking is also a risk factor for squamous cell carcinoma, as it can cause changes in the cells of the bladder lining that can lead to cancer.

      In summary, the risk factors for bladder cancer depend on the type of cancer. Urothelial carcinoma is mainly associated with smoking, exposure to aniline dyes, rubber manufacture, and cyclophosphamide, while squamous cell carcinoma is mainly associated with schistosomiasis and smoking. It is important to be aware of these risk factors and take steps to reduce your risk of developing bladder cancer.

There are no signs of a skull fracture or neurological impairment. The patient reports feeling well, has been alert since the incident, and has not experienced any vomiting. His medical history includes hypertension, atrial fibrillation, and type 2 diabetes mellitus, for which he takes amlodipine, edoxaban, and metformin, respectively. What is the next appropriate course of action?

      Your Answer: Outpatient MRI scan

      Correct Answer: CT scan within 8 hours

      Explanation:

      If a person is taking anticoagulants and has suffered a head injury, they should receive a CT head scan within 8 hours. This is the case for a 73-year-old man who sustained a head injury while gardening and is taking edoxaban. The NICE guidelines on head injury imaging algorithm recommend this course of action. An urgent CT scan within 1 hour is not necessary in this scenario as there are no risk factors for a severe head injury. Discharging the patient home with safety netting information is not appropriate, and an outpatient MRI scan is not necessary.

      NICE Guidelines for Investigating Head Injuries in Adults

      Head injuries can be serious and require prompt medical attention. The National Institute for Health and Care Excellence (NICE) has provided clear guidelines for healthcare professionals to determine which adult patients need further investigation with a CT head scan. Patients who require immediate CT head scans include those with a Glasgow Coma Scale (GCS) score of less than 13 on initial assessment, suspected open or depressed skull fractures, signs of basal skull fractures, post-traumatic seizures, focal neurological deficits, and more than one episode of vomiting.

      For patients with any loss of consciousness or amnesia since the injury, a CT head scan within 8 hours is recommended for those who are 65 years or older, have a history of bleeding or clotting disorders, experienced a dangerous mechanism of injury, or have more than 30 minutes of retrograde amnesia of events immediately before the head injury. Additionally, patients on warfarin who have sustained a head injury without other indications for a CT head scan should also receive a scan within 8 hours of the injury.

      It is important for healthcare professionals to follow these guidelines to ensure that patients receive appropriate and timely care for their head injuries. By identifying those who require further investigation, healthcare professionals can provide the necessary treatment and support to prevent further complications and improve patient outcomes.

      Explanation:

      Scaphoid Fractures and Wrist Injuries

      Scaphoid fractures are frequently seen in young adult males and are caused by a fall on an outstretched hand. If the fracture is complicated by avascular necrosis, the proximal pole is typically affected due to the scaphoid blood supply’s distal to proximal direction. Undisplaced fractures can be treated with a plaster. Wrist fractures are also common. Due to difficulties in visualizing fractures, initial radiographs usually involve four views of the scaphoid.

      In summary, scaphoid fractures and wrist injuries are prevalent in young adult males and can result from falls on outstretched hands. If complicated by avascular necrosis, the proximal pole is typically affected. Undisplaced fractures can be treated with a plaster, and initial radiographs usually involve four views of the scaphoid due to difficulties in visualizing fractures.

      Your Answer: Perform urinalysis

      Correct Answer: Perform cavernosal blood gas analysis

      Explanation:

      Cavernosal blood gas analysis is a valuable diagnostic tool for priapism, a condition characterized by a prolonged penile erection unrelated to sexual stimulation. Priapism typically affects individuals aged 5-10 years or 20-50 years. Cavernosal blood gas analysis is crucial in distinguishing between ischaemic and non-ischaemic priapism, which would inform subsequent treatment decisions.

      Priapism is a medical emergency and should be treated as such unless proven otherwise. Therefore, involving child protection services would be inappropriate in the absence of other indications of sexual abuse. Arterial blood gas analysis and urinalysis are not necessary and would be unsuitable in this case.

      Ischaemic priapism is a medical emergency that requires prompt treatment to prevent permanent tissue damage. Therefore, certain diagnostic tests must be performed, and treatment cannot be delayed. This is a critical learning point for an FY1, as priapism is prevalent in some ethnic groups and can lead to severe complications.

      Understanding Priapism: Causes, Symptoms, and Management

      Priapism is a medical condition characterized by a persistent penile erection that lasts longer than four hours and is not associated with sexual stimulation. There are two types of priapism: ischaemic and non-ischaemic, each with a different pathophysiology. Ischaemic priapism is caused by impaired vasorelaxation, resulting in reduced vascular outflow and trapping of de-oxygenated blood within the corpus cavernosa. Non-ischaemic priapism, on the other hand, is due to high arterial inflow, often caused by fistula formation due to congenital or traumatic mechanisms.

      Priapism can affect individuals of all ages, with a bimodal distribution of age at presentation, with peaks between 5-10 years and 20-50 years of age. The incidence of priapism has been estimated at up to 5.34 per 100,000 patient-years. There are various causes of priapism, including idiopathic, sickle cell disease or other haemoglobinopathies, erectile dysfunction medication, trauma, and drug use (both prescribed and recreational).

      Patients with priapism typically present acutely with a persistent erection lasting over four hours and pain localized to the penis. A history of haemoglobinopathy or medication use may also be present. Cavernosal blood gas analysis and Doppler or duplex ultrasonography can be used to differentiate between ischaemic and non-ischaemic priapism and assess blood flow within the penis. Treatment for ischaemic priapism is a medical emergency and includes aspiration of blood from the cavernosa, injection of a saline flush, and intracavernosal injection of a vasoconstrictive agent. Non-ischaemic priapism, on the other hand, is not a medical emergency and is usually observed as a first-line option.

    • You encounter a 50-year-old man who confides in you about his personal issue. He has been experiencing difficulties with achieving and maintaining erections for the past year, and it has been progressively worsening. This patient seldom visits healthcare providers and has no prior medical conditions.

      What is the predominant organic etiology for this symptom?

      Your Answer: Vascular causes

      Explanation:

      Erectile dysfunction (ED) is a symptom characterized by the persistent inability to achieve and maintain an erection sufficient for satisfactory sexual performance. The causes of ED can be categorized into organic, psychogenic, and mixed, with certain medications also contributing to the condition. Organic causes of ED include vasculogenic, neurogenic, structural, and hormonal factors, while psychogenic causes can be generalized or situational. Among the organic causes, vasculogenic factors are the most common, with cardiovascular disease, hypertension, hyperlipidemia, diabetes mellitus, smoking, and major pelvic surgery being the primary culprits. As such, the risk factors for ED are similar to those for CVD, including obesity, diabetes, dyslipidemia, metabolic syndrome, hypertension, endothelial dysfunction, and lifestyle factors such as lack of exercise and smoking. Therefore, when evaluating a man with ED, it is important to screen for CVD and obtain a thorough psychosexual history.

      Erectile dysfunction (ED) is a condition where a man is unable to achieve or maintain an erection that is sufficient for sexual activity. It is not a disease but a symptom that can be caused by organic, psychogenic, or mixed factors. It is important to differentiate between the causes of ED, with gradual onset of symptoms, lack of tumescence, and normal libido favoring an organic cause, while sudden onset of symptoms, decreased libido, and major life events favoring a psychogenic cause. Risk factors for ED include cardiovascular disease, alcohol use, and certain medications.

      To assess for ED, it is recommended to measure lipid and fasting glucose serum levels to calculate cardiovascular risk, as well as free testosterone levels in the morning. If free testosterone is low or borderline, further assessment may be needed. PDE-5 inhibitors, such as sildenafil, are the first-line treatment for ED and should be prescribed to all patients regardless of the cause. Vacuum erection devices can be used as an alternative for those who cannot or will not take PDE-5 inhibitors.

      For young men who have always had difficulty achieving an erection, referral to urology is appropriate. Additionally, people with ED who cycle for more than three hours per week should be advised to stop. Overall, ED is a common condition that can be effectively managed with appropriate treatment.

    • A 67-year-old man presents to the emergency department with central abdominal pain. He denies any fever, weight loss or recent travel. Past medical history included hypertension and appendicectomy for an inflamed appendix 3 years ago.

      On examination, there is a firm mass over the abdominal wall. The overlying skin is dusky with signs of ischaemia and necrosis.

      Given the signs of ischaemia, you perform a venous blood gas (VBG).

      pH 7.22 (7.35-7.45)
      pCO2 3.1kPa (4.5-6.0)
      pO2 5.1kPa (4.0-5.3)

      ALT 39 u/L (3 - 40)

      What is the most likely diagnosis?

      Your Answer: Diabetic ketoacidosis

      Correct Answer: Richter's hernia

      Explanation:

      Richter’s hernia can cause strangulation without any signs of obstruction. This is because the bowel lumen remains open while the bowel wall is compromised. A VBG test may reveal metabolic acidosis, indicated by a low pH, low bicarbonate, and low pCO2 due to partial respiratory compensation. This type of acidosis can occur due to lactate build-up. Unlike Richter’s hernia, small bowel obstruction is less likely to cause a firm, red mass on the abdominal wall. Conditions such as diabetic ketoacidosis and pancreatitis may cause abdominal pain and metabolic acidosis, but they do not explain the presence of a firm mass on the abdominal wall or the skin’s dusky appearance. Ascending cholangitis typically presents with Charcot’s triad, which includes right upper quadrant pain, fever, and jaundice, but this is not the case here. In some cases, it may also cause confusion and hypotension, which is known as Reynold’s pentad.

      Abdominal wall hernias occur when an organ or the fascia of an organ protrudes through the wall of the cavity that normally contains it. Risk factors for developing these hernias include obesity, ascites, increasing age, and surgical wounds. Symptoms of abdominal wall hernias include a palpable lump, cough impulse, pain, obstruction (more common in femoral hernias), and strangulation (which can compromise the bowel blood supply and lead to infarction). There are several types of abdominal wall hernias, including inguinal hernias (which account for 75% of cases and are more common in men), femoral hernias (more common in women and have a high risk of obstruction and strangulation), umbilical hernias (symmetrical bulge under the umbilicus), paraumbilical hernias (asymmetrical bulge), epigastric hernias (lump in the midline between umbilicus and xiphisternum), incisional hernias (which may occur after abdominal surgery), Spigelian hernias (rare and seen in older patients), obturator hernias (more common in females and can cause bowel obstruction), and Richter hernias (a rare type of hernia that can present with strangulation without symptoms of obstruction). In children, congenital inguinal hernias and infantile umbilical hernias are the most common types, with surgical repair recommended for the former and most resolving on their own for the latter.

      Your Answer:

      Correct Answer: Wide local excision

      Explanation:

      Breast cancer is primarily treated with surgery, with wide local excision (also known as breast conserving surgery) being the preferred option for tumours that are smaller than 4 cm.

      Breast cancer management varies depending on the stage of the cancer, type of tumor, and patient’s medical history. Treatment options may include surgery, radiotherapy, hormone therapy, biological therapy, and chemotherapy. Surgery is typically the first option for most patients, except for elderly patients with metastatic disease who may benefit more from hormonal therapy. Prior to surgery, an axillary ultrasound is recommended for patients without palpable axillary lymphadenopathy, while those with clinically palpable lymphadenopathy require axillary node clearance. The type of surgery offered depends on various factors, such as tumor size, location, and type. Breast reconstruction is also an option for patients who have undergone a mastectomy.

      Radiotherapy is recommended after a wide-local excision to reduce the risk of recurrence, while mastectomy patients may receive radiotherapy for T3-T4 tumors or those with four or more positive axillary nodes. Hormonal therapy is offered if tumors are positive for hormone receptors, with tamoxifen being used in pre- and perimenopausal women and aromatase inhibitors like anastrozole in postmenopausal women. Tamoxifen may increase the risk of endometrial cancer, venous thromboembolism, and menopausal symptoms. Biological therapy, such as trastuzumab, is used for HER2-positive tumors but cannot be used in patients with a history of heart disorders. Chemotherapy may be used before or after surgery, depending on the stage of the tumor and the presence of axillary node disease. FEC-D is commonly used in the latter case.

    • A 55-year-old male with a history of alcoholism complains of intense epigastric pain that extends to his back. During the physical examination, the epigastrium is sensitive to touch, and there are signs of bruising on the flanks. What would be a sign of a severe illness based on the probable diagnosis?

      Your Answer:

      Correct Answer: Calcium of 1.98 mmol/L

      Explanation:

      Hypocalcaemia is a sign of severe pancreatitis according to the Glasgow score, while hypercalcaemia can actually cause pancreatitis. This patient’s symptoms and history suggest acute pancreatitis, with the Glasgow score indicating potential severity. The mnemonic PANCREAS can be used to remember the criteria for severe pancreatitis, with a score of 3 or higher indicating high risk.

      Understanding Acute Pancreatitis

      Acute pancreatitis is a condition that is commonly caused by alcohol or gallstones. It occurs when the pancreatic enzymes start to digest the pancreatic tissue, leading to necrosis. The main symptom of acute pancreatitis is severe epigastric pain that may radiate through to the back. Vomiting is also common, and examination may reveal epigastric tenderness, ileus, and low-grade fever. In rare cases, periumbilical discolouration (Cullen’s sign) and flank discolouration (Grey-Turner’s sign) may be present.

      To diagnose acute pancreatitis, doctors typically measure the levels of serum amylase and lipase in the blood. While amylase is raised in 75% of patients, it does not correlate with disease severity. Lipase, on the other hand, is more sensitive and specific than amylase and has a longer half-life. Imaging tests, such as ultrasound and contrast-enhanced CT, may also be used to assess the aetiology of the condition.

      Scoring systems, such as the Ranson score, Glasgow score, and APACHE II, are used to identify cases of severe pancreatitis that may require intensive care management. Factors that indicate severe pancreatitis include age over 55 years, hypocalcaemia, hyperglycaemia, hypoxia, neutrophilia, and elevated LDH and AST. It is important to note that the actual amylase level is not of prognostic value.

      In summary, acute pancreatitis is a condition that can cause severe pain and discomfort. It is typically caused by alcohol or gallstones and can be diagnosed through blood tests and imaging. Scoring systems are used to identify cases of severe pancreatitis that require intensive care management.

      Correct Answer: Use of a laparoscopic approach over open surgery

      Explanation:

      Adhesion formation can be reduced by opting for laparoscopy over traditional surgery. The use of talc-coated surgical gloves, which was a major contributor to adhesion formation, has been discontinued. The outdated Nobles plication procedure does not aid in preventing adhesion formation. While the use of an anastomotic stapling device does not directly affect adhesion development, it is important to avoid anastomotic leaks as they can lead to increased adhesion formation.

      Complications can occur in all types of surgery and require vigilance in their detection. Anticipating likely complications and appropriate avoidance can minimize their occurrence. Understanding the anatomy of a surgical field will allow appreciation of local and systemic complications that may occur. Physiological and biochemical derangements may also occur, and appropriate diagnostic modalities should be utilized. Safe and timely intervention is the guiding principle for managing complications.

    • What is a characteristic of a trident hand?

      Your Answer:

      Correct Answer: Achondroplasia

      Explanation:

      Achondroplasia: A Genetic Disorder

      Achondroplasia is a genetic disorder that is inherited in an autosomal dominant manner. However, in about 90% of cases, it occurs as a result of a new spontaneous mutation in the genetic material. This disorder is characterized by several physical features, including an unusually large head with a prominent forehead and a flat nasal bridge. Additionally, individuals with achondroplasia have short upper arms and legs, which is known as rhizomelic dwarfism. They also have an unusually prominent abdomen and buttocks, as well as short hands with fingers that assume a trident or three-pronged position during extension.

      To summarize, achondroplasia is a genetic disorder that affects physical development. It is caused by a spontaneous mutation in the genetic material and is inherited in an autosomal dominant manner. The physical features of this disorder include a large head, short limbs, and a unique hand position. this disorder is important for individuals and families affected by it, as well as for healthcare professionals who may provide care for those with achondroplasia.

    Incorrect

    • A 58-year-old man comes to see his GP with complaints of worsening urinary symptoms. He reports frequent urges to urinate throughout the day and has experienced occasional incontinence. He denies any hesitancy, dribbling, or weak stream. Despite trying bladder retraining, he has seen little improvement.

      During the examination, the GP notes that the man's prostate is smooth, regular, and not enlarged. A recent PSA test came back normal. The patient has no medical history and is not taking any regular medications.

      What is the most appropriate course of action for managing this patient's symptoms?

      Your Answer:

      Correct Answer: Oxybutynin

      Explanation:

      Antimuscarinic drugs are a recommended treatment for patients experiencing an overactive bladder, which is characterized by storage symptoms like urgency and frequency without any voiding symptoms. If lifestyle measures and bladder training fail to alleviate symptoms, the next step is to try an antimuscarinic agent like oxybutynin, which works by blocking contractions of the detrusor muscle. Finasteride, a 5-alpha reductase inhibitor, is not suitable for this patient as it is used to treat benign prostatic hyperplasia and associated voiding symptoms. Furosemide, which increases urine production during the day and reduces it at night, is not appropriate for this patient as he does not have nocturia and it may even worsen his overactive bladder symptoms. Mirabegron, a beta-3 agonist that relaxes the detrusor muscle and increases bladder storage capacity, is a second-line medication used if antimuscarinics are not effective or well-tolerated.

      Lower urinary tract symptoms (LUTS) are a common issue in men over the age of 50, with benign prostatic hyperplasia being the most common cause. However, other causes such as prostate cancer should also be considered. These symptoms can be classified into three groups: voiding, storage, and post-micturition. To properly manage LUTS, it is important to conduct a urinalysis to check for infection and haematuria, perform a digital rectal examination to assess the size and consistency of the prostate, and possibly conduct a PSA test after proper counselling. Patients should also complete a urinary frequency-volume chart and an International Prostate Symptom Score to guide management.

      For predominantly voiding symptoms, conservative measures such as pelvic floor muscle training, bladder training, and prudent fluid intake can be helpful. If symptoms are moderate or severe, an alpha-blocker may be offered. If the prostate is enlarged and the patient is at high risk of progression, a 5-alpha reductase inhibitor should be offered. If there are mixed symptoms of voiding and storage not responding to an alpha-blocker, an antimuscarinic drug may be added. For predominantly overactive bladder symptoms, moderating fluid intake and bladder retraining should be offered, and antimuscarinic drugs may be prescribed if symptoms persist. Mirabegron may be considered if first-line drugs fail. For nocturia, moderating fluid intake at night, furosemide 40 mg in the late afternoon, and desmopressin may be helpful.

    Incorrect

    • A 75-year-old man has been experiencing difficulty passing urine for the past 6 hours and is in significant discomfort. Upon catheterization, 1 litre of urine is drained and the patient experiences relief. During a PR examination, an enlarged, hard, nodular prostate is detected. The Urology Registrar advises admission and observation for 24 hours due to the risk of complications following an episode of acute urinary retention. What is the most crucial test to repeat within the next 12 hours to aid in identifying such a complication?

      Your Answer:

      Correct Answer: Serum creatinine

      Explanation:

      This man experienced sudden inability to urinate and upon examination, it appears that his enlarged prostate (possibly due to cancer) is the cause. Acute kidney damage can occur as a result of this condition, so the best course of action is to test his serum creatinine levels. It’s crucial to closely monitor his fluid intake over the next two days as some patients may experience excessive urination after a catheter is inserted. Additionally, it’s important to note that the PSA levels may be inaccurately elevated after catheterization.

      Prostate cancer is currently the most prevalent cancer among adult males in the UK, and the second most common cause of cancer-related deaths in men, following lung cancer. The risk factors for prostate cancer include increasing age, obesity, Afro-Caribbean ethnicity, and a family history of the disease, which accounts for 5-10% of cases. Localized prostate cancer is often asymptomatic, as the cancer tends to develop in the outer part of the prostate gland, causing no obstructive symptoms in the early stages. However, some possible features of prostate cancer include bladder outlet obstruction, haematuria or haematospermia, and pain in the back, perineal or testicular area. A digital rectal examination may reveal asymmetrical, hard, nodular enlargement with loss of median sulcus. In addition, an isotope bone scan can be used to detect metastatic prostate cancer, which appears as multiple, irregular, randomly distributed foci of high-grade activity involving the spine, ribs, sternum, pelvic and femoral bones.
