      When would a social services referral be indicated in the first instance?

      Your Answer: Only after discussion with the safeguarding lead

      Correct Answer: If you suspect a child is being maltreated or you feel the family could benefit from some extra support

      Explanation:

      When to Make a Referral to Social Services for Child Protection

      As a healthcare professional, it is important to know when to make a referral to social services for child protection. Here are some situations that require immediate action:

      1. Suspected maltreatment or need for extra support: If you suspect a child is being maltreated or you feel the family could benefit from some extra support, a referral must be made urgently to social services. Follow up within 48 hours with written confirmation.

      2. Immediate danger: If you feel a child needs to be removed from premises immediately for their safety, inform the police immediately. Once the child is considered to be in a place of safety, social services will be informed.

      3. Recent sexual assault: If the child has disclosed a recent sexual assault, they would need to be referred urgently for forensic examination. Following this, social services will be likely to be informed.

      4. Discussion with safeguarding lead: If you feel confident in your judgement, you do not have to seek advice from the safeguarding lead before every referral. If you suspect a child is at risk of harm, it is your responsibility to take action to ensure the child’s safety.

      5. Consent of parent and/or patient: Always try to gain consent from the parent or patient before making a referral to social services. If consent is refused, the referral can still be made, but it is important that the patient/parent is fully informed of your actions.

    Correct

    • A 30-year-old woman presents to you with complaints of feeling down and fatigued. She struggles to fall asleep at night and has difficulty getting up in the morning. Despite her love for exercise, she lacks motivation and finds it hard to engage in physical activity.

      What is the duration of her symptoms that would warrant a diagnosis of a depressive episode?

      Your Answer: Two weeks

      Explanation:

      DSM-IV Criteria for Diagnosing Depression

      Depression is a mental health condition that can significantly impact a person’s daily life. The National Institute for Health and Care Excellence (NICE) has adopted the DSM-IV criteria for diagnosing depression. The key symptoms include persistent sadness or low mood and marked loss of interests or pleasure. These symptoms must be present for at least two weeks, most days, most of the time.

      In addition to the core symptoms, other associated symptoms may include disturbed sleep, changes in appetite and weight, fatigue, agitation or slowing of movements, poor concentration or indecisiveness, feelings of worthlessness or excessive guilt, and suicidal thoughts or acts.

      It is important to note that these symptoms can vary in duration. Some individuals may experience symptoms for only two days, while others may experience them for up to two months. If you or someone you know is experiencing symptoms of depression, it is important to seek professional help.

      What medication would be appropriate to administer to this individual?

      Your Answer: Zopiclone

      Correct Answer: Olanzapine

      Explanation:

      Choosing the Right Medication for Psychosis: A Comparison of Olanzapine, Diazepam, Citalopram, Clozapine, and Zopiclone

      When a patient presents with psychosis, it is crucial to assess them urgently and rule out any organic medical causes. The primary treatment for psychosis is antipsychotics, such as olanzapine. While benzodiazepines like diazepam can be used to treat agitation associated with acute psychosis, they are not the first-line treatment. Citalopram, a selective serotonin reuptake inhibitor used for depression, would not be appropriate for treating psychosis. Clozapine, another antipsychotic, is only used on specialist advice due to the risk of agranulocytosis. Zopiclone, a hypnotic used for sleep, is not appropriate for treating psychosis. It is important to choose the right medication for psychosis to ensure the best possible outcome for the patient.

    Incorrect

    • Which of the following is not a factor that contributes to sensorineural hearing loss?

      Your Answer: Gentamicin toxicity

      Correct Answer: Early otosclerosis

      Explanation:

      Hearing Loss and Cochlear Implants

      Hearing loss can be classified into two types: conductive and sensorineural. Conductive hearing loss affects the outer and middle ear, while sensorineural hearing loss affects the cochlea in the inner ear. Cochlear implants are a solution for sensorineural hearing loss, as they provide direct electrical stimulation to the auditory nerve fibers in the cochlea to replicate the function of damaged hair cells.

      There are various causes of hair cell damage, including gentamicin toxicity, bacterial meningitis, skull fractures, noise exposure, presbycusis, genetic syndromes, hereditary deafness, and unknown factors. Otosclerosis is another cause of hearing loss, resulting from an overgrowth of bone in the middle ear that fixes the footplate of the stapes at the oval window, leading to conductive hearing loss. If left untreated for an extended period, the cochlea can also become affected, resulting in a mixed hearing loss that is both conductive and sensorineural.

      In summary, the different types and causes of hearing loss is crucial in finding the appropriate treatment. Cochlear implants are a viable solution for sensorineural hearing loss, while conductive hearing loss may require different interventions. It is essential to seek medical attention and diagnosis to determine the best course of action for hearing loss.

    Incorrect

    • A 55-year-old obese woman, who recently returned from a trip to Japan, presents with chronic diarrhoea, fatigue, and greasy, bulky stools. She is a non-smoker and non-drinker who consumes meat. Stool examination confirms steatorrhoea, and blood tests reveal elevated folic acid levels and reduced vitamin B12 levels. The only abnormal finding on a CT scan of the abdomen is multiple diverticula in the jejunum. What is the most likely cause of this patient's macrocytic anaemia?

      Your Answer: Chronic pancreatic insufficiency

      Correct Answer: Increased utilisation of vitamin B12 by bacteria

      Explanation:

      Causes of Vitamin B12 Deficiency: An Overview

      Vitamin B12 deficiency can be caused by various factors, including bacterial overgrowth syndrome, acquired deficiency of intrinsic factor, chronic pancreatic insufficiency, dietary deficiency, and fish tapeworm infestation.

      Bacterial Overgrowth Syndrome: This disorder is characterized by the proliferation of colonic bacteria in the small bowel, resulting in diarrhea, steatorrhea, and macrocytic anemia. The bacteria involved are usually Escherichia coli or Bacteroides, which can convert conjugated bile acids to unconjugated bile acids, leading to impaired micelle formation and steatorrhea. The bacteria also utilize vitamin B12, causing macrocytic anemia.

      Acquired Deficiency of Intrinsic Factor: This condition is seen in pernicious anemia, which does not have diarrhea or steatorrhea.

      Chronic Pancreatic Insufficiency: This is most commonly associated with chronic pancreatitis caused by high alcohol intake or cystic fibrosis. However, in this case, the patient has no history of alcohol intake or CF, and blood tests do not reveal hyperglycemia. CT abdomen can detect calcification of the pancreas, characteristic of chronic pancreatitis.

      Dietary Deficiency of Vitamin B12: This is unlikely in non-vegetarians like the patient in this case.

      Fish Tapeworm Infestation: This infestation can cause vitamin B12 deficiency, but it is more common in countries where people commonly eat raw freshwater fish. In this case, the presence of diarrhea, steatorrhea, and CT abdomen findings suggestive of jejunal diverticula make bacterial overgrowth syndrome more likely.

      In conclusion, vitamin B12 deficiency can have various causes, and a thorough evaluation is necessary to determine the underlying condition.

    Incorrect

    • A 83-year-old woman presents with urinary frequency and dysuria. She reports that her urine appears bubbly. Over the past year, she has been treated for UTI five times. Her medical history includes hypertension, which is managed with amlodipine. On examination, she has mild suprapubic tenderness but no other significant findings. Her vital signs are heart rate 88/min, blood pressure 128/84 mmHg, respiratory rate 22/min, temperature 37.3ºC, and saturation 93%. A urine dipstick reveals the following: Blood +, Protein +, Leucocytes ++, Nitrites ++. What is the most likely diagnosis?

      Your Answer: Pyelonephritis

      Correct Answer: Enterovesical fistula

      Explanation:

      The presence of bubbly urine in a woman with recurrent UTIs may indicate an enterovesical fistula, which is a connection between the bowel and bladder. This condition is often associated with colorectal cancer, as suggested by the patient’s tissue wasting. It is important to investigate this possibility. There are no symptoms of pyelonephritis or bladder stones, which would not cause gas in the urine. While the patient’s wasting could be a sign of malignancy, there is no indication that it is endometrial cancer, which typically presents with postmenopausal bleeding. The most common organism in UTIs is E. coli, which is a facultative anaerobe and does not produce large amounts of gas.

      Fistulas are abnormal connections between two epithelial surfaces, with the majority arising from diverticular disease and Crohn’s in the abdominal cavity. They can be enterocutaneous, enteroenteric or enterocolic, enterovaginal, or enterovesicular. Conservative measures may be the best option for management, but high output fistulas may require octreotide and TPN for nutritional support. Surgeons should avoid probing perianal fistulae with acute inflammation and use setons for those secondary to Crohn’s disease. It is important to delineate the fistula anatomy using barium and CT studies for intraabdominal sources and recalling Goodsall’s rule for perianal fistulae.

    • Samantha is a 65-year-old with a history of type 2 diabetes who has reported experiencing occasional tingling in her right 4th and 5th fingers. What is the probable diagnosis?

      Your Answer: Cubital tunnel syndrome

      Explanation:

      Cubital tunnel syndrome occurs when the ulnar nerve is compressed, leading to numbness and tingling in the 4th and 5th fingers. This condition is typically caused by entrapment of the nerve at the elbow and is more common in individuals with diabetes. Carpal tunnel syndrome, on the other hand, is caused by compression of the median nerve in the wrist and affects the first three fingers and part of the 4th finger. While it is possible for multiple sclerosis to cause similar symptoms, it is less likely. Alcohol abuse and… (sentence incomplete)

      Understanding Cubital Tunnel Syndrome

      Cubital tunnel syndrome is a condition that occurs when the ulnar nerve is compressed as it passes through the cubital tunnel. This can cause a range of symptoms, including tingling and numbness in the fourth and fifth fingers, which may start off intermittent but eventually become constant. Over time, patients may also experience weakness and muscle wasting. Pain is often worse when leaning on the affected elbow, and there may be a history of osteoarthritis or prior trauma to the area.

      Diagnosis of cubital tunnel syndrome is usually made based on clinical features, although nerve conduction studies may be used in selected cases. Management of the condition typically involves avoiding aggravating activities, undergoing physiotherapy, and receiving steroid injections. In cases where these measures are not effective, surgery may be necessary. By understanding the symptoms and treatment options for cubital tunnel syndrome, patients can take steps to manage their condition and improve their quality of life.

    Correct

    • A 45-year-old patient comes to the clinic for immunisations before their trip to Thailand. They stopped taking amiodarone a month ago due to hypothyroidism and are currently on a daily dose of bisoprolol 5 mg. The patient inquires about any extra precautions they should take during their vacation. What is your advice?

      Your Answer: Keep skin covered and use high factor sunscreen

      Explanation:

      Precautions for Amiodarone Use

      Amiodarone, a medication used to treat heart rhythm disorders, may cause phototoxic reactions in patients. To prevent such reactions, patients are advised to protect their skin from direct sunlight and use a high-factor sunscreen. These precautions should be taken not only during treatment but also for several months after discontinuing amiodarone due to its long half-life, which can last for weeks to months. It is important for patients to be aware of these precautions and to follow them closely to avoid any potential adverse effects.

    • A 65-year-old man presents with a 1-hour history of chest pain and is found to have an acute ST elevation inferior myocardial infarct. His blood pressure is 126/78 mmHg and has a pulse of 58 bpm. He is loaded with anti-platelets, and the cardiac monitor shows second-degree heart block (Wenckebach’s phenomenon).
      What would you consider next for this patient?

      Your Answer: Primary PCI and permanent pacemaker

      Correct Answer: Temporary pacing and primary PCI

      Explanation:

      Management of Heart Block in Acute Myocardial Infarction

      Wenckebach’s phenomenon is usually not a cause for concern in patients with normal haemodynamics. However, if it occurs alongside acute myocardial infarction, complete heart block, or symptomatic Mobitz type II block, temporary pacing is necessary. Even with complete heart block, revascularisation can improve conduction if the patient is haemodynamically stable. Beta blockers should be avoided in second- and third-degree heart block as they can worsen the situation. Temporary pacing is required before proceeding to primary percutaneous intervention (PCI). A permanent pacemaker may be necessary for patients with irreversible heart block, but revascularisation should be prioritised as it may improve conduction. The block may be complete or second- or third-degree. If the heart block is reversible, temporary pacing should be followed by an assessment for permanent pacing.

      Your Answer: Cross-sectional survey

      Correct Answer: Case-control study

      Explanation:

      Different Study Designs for Investigating Rare Diseases

      When investigating a rare disease, it is important to choose the appropriate study design to ensure accurate and reliable results. Here are some common study designs and their suitability for studying rare diseases:

      1. Case-control study: This design compares individuals affected by the disease (cases) with those not affected (controls) to identify potential risk factors. It is useful for rare diseases, but careful selection of controls is necessary to avoid bias.

      2. Cohort study: This design follows a group of individuals with a particular exposure or characteristic over time to determine if they develop the disease. While useful, it requires a large cohort and a long follow-up period for rare diseases.

      3. Placebo-controlled randomized trial: This design tests interventions prospectively and is not helpful for investigating rare diseases.

      4. Descriptive study: This design does not determine exposure to the hypothesized cause of the disease and is not helpful for investigating rare diseases.

      5. Cross-sectional survey: This design records health information from a random sample of people and requires a large sample size for rare diseases.

      Choosing the appropriate study design is crucial for investigating rare diseases and obtaining accurate results.

    • How does the combination of gentamicin and benzylpenicillin work together to treat infective endocarditis caused by Streptococcus viridans?

      Your Answer: Inhibition of protein synthesis (transcription)

      Correct Answer: Inhibition of protein synthesis (translation)

      Explanation:

      Synergistic Action of Gentamicin and Benzylpenicillin

      Gentamicin and benzylpenicillin work together to effectively combat bacterial infections. Benzylpenicillin is a bactericidal agent that prevents the synthesis of the bacterial cell wall, which allows gentamicin to enter the bacterial cell. Gentamicin then acts on the ribosome, inhibiting protein synthesis and ultimately killing the bacteria. This synergistic action of the two drugs is a powerful tool in the fight against bacterial infections. The combination of these drugs is often used in clinical settings to treat a variety of bacterial infections.

    Incorrect

    • A 65-year-old woman comes to her GP complaining of pain and stiffness in both knees and hands for a few months. She also reports swelling in her left index finger. Apart from hypertension, for which she takes amlodipine, and a cough that is currently being investigated, she is in good health and has no significant medical history. During the examination, the doctor notices dactylitis in her left index finger, as well as general pain and limited mobility in her fingers. X-rays of her hands reveal erosions in the distal interphalangeal (DIP) joint on both sides. What diagnosis is most consistent with these findings?

      Your Answer: Osteoarthritis

      Correct Answer: Psoriatic arthritis

      Explanation:

      The presence of DIP joint swelling and dactylitis in inflammatory arthritis suggests a diagnosis of psoriatic arthritis. Although there is not always a clear correlation between psoriatic arthritis and cutaneous psoriasis, arthritic symptoms often appear before skin lesions. While there may be some overlap with rheumatoid arthritis, the presence of DIP joint disease and dactylitis are more indicative of psoriatic arthritis. Gout is an unlikely diagnosis as it typically presents as acute and monoarticular or oligoarticular, without the other symptoms seen here. Osteoarthritis is also an unlikely diagnosis as it typically presents asymmetrically in larger joints and does not typically present with dactylitis or the findings seen on X-ray. Rheumatoid arthritis is a possibility, but a blood test for anti-cyclic citrullinated peptide antibodies (anti-CCP) should be performed to confirm the diagnosis, as these antibodies are highly specific to rheumatoid arthritis and are usually absent in psoriatic arthritis.

      Psoriatic arthropathy is a type of inflammatory arthritis that is associated with psoriasis. It is classified as one of the seronegative spondyloarthropathies and is known to have a poor correlation with cutaneous psoriasis. In fact, it often precedes the development of skin lesions. This condition affects both males and females equally, with around 10-20% of patients with skin lesions developing an arthropathy.

      The presentation of psoriatic arthropathy can vary, with different patterns of joint involvement. The most common type is symmetric polyarthritis, which is very similar to rheumatoid arthritis and affects around 30-40% of cases. Asymmetrical oligoarthritis is another type, which typically affects the hands and feet and accounts for 20-30% of cases. Sacroiliitis, DIP joint disease, and arthritis mutilans (severe deformity of fingers/hand) are other patterns of joint involvement. Other signs of psoriatic arthropathy include psoriatic skin lesions, periarticular disease, enthesitis, tenosynovitis, dactylitis, and nail changes.

      To diagnose psoriatic arthropathy, X-rays are often used. These can reveal erosive changes and new bone formation, as well as periostitis and a pencil-in-cup appearance. Management of this condition should be done by a rheumatologist, and treatment is similar to that of rheumatoid arthritis. However, there are some differences, such as the use of monoclonal antibodies like ustekinumab and secukinumab. Mild peripheral arthritis or mild axial disease may be treated with NSAIDs alone, rather than all patients being on disease-modifying therapy as with RA. Overall, psoriatic arthropathy has a better prognosis than RA.

    Incorrect

    • A 67-year-old man is seen on the ward round, 5 days after a radical cystectomy and ileal conduit formation surgery for bladder cancer. The patient complains of abdominal bloating and has vomited twice. Upon examination, the patient's abdomen is distended, without signs of flank bruising. The wound dressings are dry, and the stoma appears healthy with good urine output. The patient's observations are within normal limits. Laboratory results show a hemoglobin level of 138 g/L (male: 135-180; female: 115-160), platelets of 380 * 109/L (150-400), a white blood cell count of 18.9 * 109/L (4.0-11.0), and a CRP level of 122 mg/L (<5). What is the most likely diagnosis?

      Your Answer: Anastomotic leak

      Correct Answer: Ileus

      Explanation:

      A 64-year-old man who recently underwent radical cystectomy and ileal conduit formation surgery is experiencing abdominal pain, bloating, and vomiting. The most probable diagnosis is post-operative ileus, which is a complication of bowel surgery that causes a temporary reduction in intestinal muscle activity, resulting in stasis. The patient’s blood tests show elevated white cells and CRP, which is typical after surgery. Anastomotic leak is a possible differential diagnosis, but the patient’s distended abdomen and normal clinical observations make it less likely than ileus. Bladder distension is not a possible diagnosis since the patient no longer has a bladder. Retroperitoneal hemorrhage is another potential postoperative complication, but it is not described in this scenario, which only mentions abdominal pain, reduced hemoglobin, and bruising on the abdomen as symptoms.

      Postoperative ileus, also known as paralytic ileus, is a common complication that can occur after bowel surgery, particularly if the bowel has been extensively handled. This condition is characterized by a reduction in bowel peristalsis, which can lead to pseudo-obstruction. Symptoms of postoperative ileus include abdominal distention, bloating, pain, nausea, vomiting, inability to pass flatus, and difficulty tolerating an oral diet. It is important to check for deranged electrolytes, such as potassium, magnesium, and phosphate, as they can contribute to the development of postoperative ileus.

      The management of postoperative ileus typically involves starting with nil-by-mouth and gradually progressing to small sips of clear fluids. If vomiting occurs, a nasogastric tube may be necessary. Intravenous fluids are administered to maintain normovolaemia, and additives may be used to correct any electrolyte disturbances. In severe or prolonged cases, total parenteral nutrition may be required. It is important to monitor the patient closely and adjust the treatment plan as necessary to ensure a successful recovery.

      Explanation:

      Managing Acute Pancreatitis in a Hospital Setting

      Acute pancreatitis is a serious condition that requires management in a hospital setting. The severity of the condition can be stratified based on the presence of organ failure and local complications. Key aspects of care include fluid resuscitation, aggressive early hydration with crystalloids, and adequate pain management with intravenous opioids. Patients should not be made ‘nil-by-mouth’ unless there is a clear reason, and enteral nutrition should be offered within 72 hours of presentation. Antibiotics should not be used prophylactically, but may be indicated in cases of infected pancreatic necrosis. Surgery may be necessary for patients with acute pancreatitis due to gallstones or obstructed biliary systems, and those with infected necrosis may require radiological drainage or surgical necrosectomy.

    • A 65-year-old man presents with weakness and a skin rash on his upper eyelids. He also complains of a cough which has been present for 3 months. He has a 50 pack-year smoking history. On examination he is noted to have symmetrical proximal muscle weakness.
      What is the most appropriate test from the options below?

      Your Answer: Anti-CCP (cyclic citrullinated peptide) antibody

      Correct Answer: Anti-Jo 1 antibody

      Explanation:

      The symptoms indicate the possibility of dermatomyositis, and the presence of anti-Jo 1 antibody can aid in confirming the diagnosis.

      Dermatomyositis is a condition that causes inflammation and muscle weakness, as well as distinct skin lesions. It can occur on its own or be associated with other connective tissue disorders or underlying cancers, particularly ovarian, breast, and lung cancer. Screening for cancer is often done after a diagnosis of dermatomyositis. Polymyositis is a variant of the disease that does not have prominent skin manifestations.

      The skin features of dermatomyositis include a photosensitive macular rash on the back and shoulders, a heliotrope rash around the eyes, roughened red papules on the fingers’ extensor surfaces (known as Gottron’s papules), extremely dry and scaly hands with linear cracks on the fingers’ palmar and lateral aspects (known as mechanic’s hands), and nail fold capillary dilation. Other symptoms may include proximal muscle weakness with tenderness, Raynaud’s phenomenon, respiratory muscle weakness, interstitial lung disease (such as fibrosing alveolitis or organizing pneumonia), dysphagia, and dysphonia.

      Investigations for dermatomyositis typically involve testing for ANA antibodies, which are positive in around 80% of patients. Approximately 30% of patients have antibodies to aminoacyl-tRNA synthetases, including antibodies against histidine-tRNA ligase (also called Jo-1), antibodies to signal recognition particle (SRP), and anti-Mi-2 antibodies.

      Tardive dyskinesia is a condition where patients on long-term anti-dopaminergic medication, such as antipsychotics, may experience involuntary muscle movements in various parts of their body. Akathisia is another symptom associated with antipsychotic use, where patients experience restlessness and an inability to remain still. Serotonin syndrome can occur when patients take an overdose or combination of certain medications, resulting in symptoms such as ataxia, agitation, and tremors. Acute dystonia refers to muscle contractions following the administration of a neuroleptic agent. Neuroleptic malignant syndrome is a potentially life-threatening condition associated with the use of antipsychotic medication, characterized by hyperthermia, muscle rigidity, and changes in consciousness. Treatment involves discontinuing the medication and providing supportive care.

    Incorrect

    • A 67-year-old woman arrives at the Emergency Department by ambulance with chest pain that began 45 minutes ago. An ECG is performed and shows ST elevation in leads V1-V6, with ST depression in leads III and aVF. The closest facility capable of providing primary PCI is a 2 hour transfer time by ambulance. What is the most appropriate course of action for this patient?

      Your Answer: Aspirin, clopidogrel, low-molecular-weight heparin, and transfer for PCI

      Correct Answer: Administer thrombolysis and transfer for PCI

      Explanation:

      Management of ST Elevation Myocardial Infarction in Remote Locations

      ST elevation myocardial infarction (STEMI) is a medical emergency that requires prompt treatment. Percutaneous coronary intervention (PCI) is the gold standard first-line treatment for STEMI, but in remote locations, the patient may need to be taken to the nearest facility for initial assessment prior to transfer for PCI. In such cases, the most appropriate management strategy should be considered to minimize time delays and optimize patient outcomes.

      Administer Thrombolysis and Transfer for PCI

      In cases where the transfer time to the nearest PCI facility is more than 120 minutes, fibrinolysis prior to transfer should be strongly considered. This is particularly important for patients with anterior STEMI, where time is of the essence. Aspirin, clopidogrel, and low-molecular-weight heparin should also be administered, and the patient should be transferred to a PCI-delivering facility as soon as possible.

      Other Treatment Options

      If PCI is not likely to be achievable within 120 minutes of when fibrinolysis could have been given, thrombolysis should be administered prior to transfer. Analgesia alone is not sufficient, and unfractionated heparin is not the optimum treatment for STEMI.

      Conclusion

      In remote locations, the management of STEMI requires careful consideration of the potential time delays involved in transferring the patient to a PCI-delivering facility. Administering thrombolysis prior to transfer can help minimize delays and improve patient outcomes. Aspirin, clopidogrel, and low-molecular-weight heparin should also be administered, and the patient should be transferred to a PCI-delivering facility as soon as possible.

    Correct

    • A 35-year-old man is brought to his GP by his partner who is concerned he may have developed bipolar disorder over the last few months.
      The man experiences periods of elevated mood, where he spends a lot of money and sleeps very little. He denies having any delusions of grandeur. These episodes usually last for a few days, and he has never put himself or others in danger.
      The man also has episodes of severe depression, where he feels suicidal, loses interest in his hobbies, and sleeps excessively. He is referred to a psychiatrist for further evaluation.
      What is the most probable diagnosis?

      Your Answer: Type 2 bipolar disorder

      Explanation:

      The woman’s alternating episodes of hypomania and severe depression suggest that she has type 2 bipolar disorder. There are no indications of an anxiety disorder, and the severity of her symptoms is not consistent with cyclothymia. Major depressive disorder is also not a likely diagnosis, as she experiences ‘highs’ consistent with hypomania. Type 1 bipolar disorder is also unlikely, as her ‘high’ periods are more in line with hypomania rather than full-blown mania.

      Understanding Bipolar Disorder

      Bipolar disorder is a mental health condition that is characterized by alternating periods of mania/hypomania and depression. It typically develops in the late teen years and has a lifetime prevalence of 2%. There are two recognized types of bipolar disorder: type I, which involves mania and depression, and type II, which involves hypomania and depression.

      Mania and hypomania both refer to abnormally elevated mood or irritability, but mania is more severe and can include psychotic symptoms for 7 days or more. Hypomania, on the other hand, involves decreased or increased function for 4 days or more. The presence of psychotic symptoms suggests mania.

      Management of bipolar disorder may involve psychological interventions specifically designed for the condition, as well as medication. Lithium is the mood stabilizer of choice, but valproate can also be used. Antipsychotic therapy, such as olanzapine or haloperidol, may be used to manage mania/hypomania, while fluoxetine is the antidepressant of choice for depression. It is important to address any co-morbidities, as there is an increased risk of diabetes, cardiovascular disease, and COPD in individuals with bipolar disorder.

      If symptoms suggest hypomania, routine referral to the community mental health team (CMHT) is recommended. However, if there are features of mania or severe depression, an urgent referral to the CMHT should be made. Understanding bipolar disorder and its management is crucial for healthcare professionals to provide appropriate care and support for individuals with this condition.

    Incorrect

    • An 80-year-old man presents to the emergency department with a headache on the right side of his head. The pain is concentrated in his right temple and worsens when he moves his jaw. He reports no changes in vision or focal neurological symptoms. The patient has a medical history of polymyalgia rheumatica. A temporal artery biopsy is scheduled to confirm the diagnosis. What is the next best course of action in managing this patient?

      Your Answer: Immediate oral dexamethasone

      Correct Answer: Immediate oral prednisolone

      Explanation:

      When temporal arthritis is suspected, glucocorticoids should be administered immediately without waiting for a temporal artery biopsy. This condition, also known as giant cell arthritis, typically presents with a localized headache in the temporal region and jaw claudication. It is strongly associated with polymyalgia rheumatica. Prompt treatment is essential as temporal arthritis is a medical emergency that can lead to serious complications. Oral prednisolone is the recommended treatment in the absence of vision changes. Analgesia alone is not sufficient, and waiting for biopsy results can cause unnecessary delays in treatment. IV methylprednisolone is only indicated if there are changes in vision. Oral dexamethasone is not recommended as there is limited evidence on its efficacy for giant cell arthritis. Therefore, prednisolone is the preferred first-line treatment.

      Temporal arthritis, also known as giant cell arthritis, is a condition that affects medium and large-sized arteries and is of unknown cause. It typically occurs in individuals over the age of 50, with the highest incidence in those in their 70s. Early recognition and treatment are crucial to minimize the risk of complications, such as permanent loss of vision. Therefore, when temporal arthritis is suspected, urgent referral for assessment by a specialist and prompt treatment with high-dose prednisolone is necessary.

      Temporal arthritis often overlaps with polymyalgia rheumatica, with around 50% of patients exhibiting features of both conditions. Symptoms of temporal arthritis include headache, jaw claudication, and tender, palpable temporal artery. Vision testing is a key investigation in all patients, as anterior ischemic optic neuropathy is the most common ocular complication. This results from occlusion of the posterior ciliary artery, leading to ischemia of the optic nerve head. Fundoscopy typically shows a swollen pale disc and blurred margins. Other symptoms may include aching, morning stiffness in proximal limb muscles, lethargy, depression, low-grade fever, anorexia, and night sweats.

      Investigations for temporal arthritis include raised inflammatory markers, such as an ESR greater than 50 mm/hr and elevated CRP. A temporal artery biopsy may also be performed, and skip lesions may be present. Treatment for temporal arthritis involves urgent high-dose glucocorticoids, which should be given as soon as the diagnosis is suspected and before the temporal artery biopsy. If there is no visual loss, high-dose prednisolone is used. If there is evolving visual loss, IV methylprednisolone is usually given prior to starting high-dose prednisolone. Urgent ophthalmology review is necessary, as visual damage is often irreversible. Other treatments may include bone protection with bisphosphonates and low-dose aspirin.

    Correct

    • A 35-year-old woman presents to the Gastroenterology Clinic with a history of intermittent dysphagia to both solids and liquids for the past 6 months. She reports that food often gets stuck during meals and she has to drink a lot of water to overcome this. The doctor orders a chest X-ray and barium swallow, which reveal a dilated oesophagus, lack of peristalsis, and bird-beak deformity.
      What diagnosis is consistent with these symptoms and test results?

      Your Answer: Achalasia

      Explanation:

      Achalasia is a condition where the lower oesophageal sphincter fails to relax during swallowing, causing difficulty in swallowing both solids and liquids. The cause is often unknown, and diagnosis involves various tests such as chest X-ray, barium swallow, oesophagoscopy, CT scan, and manometry. Treatment options include sphincter dilation using Botox or balloon dilation, and surgery if necessary. Oesophageal web is a thin membrane in the oesophagus that can cause dysphagia to solids and reflux symptoms. Chagas’ disease, scleroderma, and diffuse oesophageal spasm are other conditions that can cause similar symptoms but have different causes and treatments.
