A 72-year-old woman comes to the clinic with a 6-week history of an itchy rash. The rash appeared on the medial and anterior aspects of the thigh and the trunk. It consisted of numerous small fluid-filled vesicles and a number of larger lesions measuring 2-3 cm, filled with serous fluid. Many of the lesions have burst, leaving erosions.
Which of the following is the most likely diagnosis?Your Answer: Bullous pemphigoid
Explanation:Common Blistering Skin Conditions: Causes and Symptoms
Blisters on the skin can be caused by various conditions, each with their own unique symptoms. Here are some common blistering skin conditions and their characteristics:
1. Bullous pemphigoid: This autoimmune disorder results in blisters that are tense and do not rupture easily. They are usually symmetrical and appear on the trunk and limbs, with the mouth being affected in some cases.
2. Dermatitis herpetiformis: This condition causes intensely itchy vesicles on the elbows, knees, and buttocks. It is associated with gluten intolerance and coeliac disease, and can be controlled by excluding gluten from the diet.
3. Bullous impetigo: This superficial infection is caused by Staphylococcus aureus or Streptococcus spp. and results in a golden-crusted eruption on a red base. Occasionally, a toxin produced by the organism can cause a blister.
4. Scabies: This condition causes itchy papules and burrows of the scabies mite on the finger webs, elbows, ankles, axillae, and genitalia. In rare cases, it can cause blistering. Norwegian (crusted) scabies is a severe form that occurs in immunosuppressed individuals.
5. Vesicular insect bite eruption: Insect bites can occasionally result in tense blisters on a wheal at the site of the bite. They are usually short-lived and accompanied by itching.
If you experience blistering skin, it is important to seek medical attention to determine the underlying cause and receive appropriate treatment.

A 28-year-old woman has taken Ellaone (ulipristal) as emergency contraception within 96 hours of unprotected sex. After consulting with you, her GP, she has decided to begin taking the combined contraceptive pill. What guidance do you provide her regarding commencing the combined contraceptive pill following the use of Ellaone?
Your Answer: Start the pill after 5 days and use barrier contraception for a further 7 days
Explanation:When using Ellaone, it is recommended to wait for 5 days before starting the combined contraceptive pill and to use barrier contraception for 7 days. This is because taking progestogen within 5 days of using Ulipristal may reduce its effectiveness as an emergency contraceptive. Waiting for this period and avoiding further unprotected sexual intercourse ensures that Ellaone is as effective as possible in preventing pregnancy. When starting the combined contraceptive pill, patch, or ring, or the progesterone-only implant or injection, barrier contraception should be used for 7 days. For Qlaira contraceptive pill, barrier contraceptives should be used for 9 days, and for the progesterone-only pill, for 2 days after starting the method.
Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, and should be taken as soon as possible after unprotected sexual intercourse (UPSI) for maximum efficacy. The single dose of levonorgestrel is 1.5mg, but should be doubled for those with a BMI over 26 or weight over 70kg. It is safe and well-tolerated, but may cause vomiting in around 1% of women. Ulipristal, on the other hand, is a selective progesterone receptor modulator that inhibits ovulation. It should be taken within 120 hours after intercourse, and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which may inhibit fertilization or implantation. It must be inserted within 5 days of UPSI, or up to 5 days after the likely ovulation date. Prophylactic antibiotics may be given if the patient is at high-risk of sexually transmitted infection. The IUD is 99% effective regardless of where it is used in the cycle, and may be left in-situ for long-term contraception.

Samantha, a 50-year-old woman, visits her doctor complaining of feeling fatigued, experiencing a low mood, and losing interest in activities she typically enjoys for the past two weeks. As per ICD-10 guidelines, how long must Samantha's symptoms persist to be diagnosed with a depressive episode?
Your Answer: 2 weeks
Explanation:The criteria for diagnosing depressive illness according to ICD-10 include a depressed mood, loss of interest in activities that were once enjoyable, and decreased energy levels. Other common symptoms include reduced concentration, low self-esteem, feelings of guilt, pessimistic views of the future, and thoughts or actions of self-harm or suicide. Disturbed sleep, diminished appetite, psychomotor agitation or retardation, and loss of libido are also common.
To diagnose a mild depressive episode, at least two of the main three symptoms and two of the other symptoms should be present, but none of the symptoms should be intense. The episode should last for a minimum of two weeks, and individuals should still be able to function socially and at work, despite being distressed by the symptoms.
For a moderate depressive episode, at least two of the main three symptoms and three or four of the other symptoms should be present for a minimum of two weeks. Individuals will likely have difficulty continuing with normal work and social functioning.
A severe depressive episode is diagnosed when all three typical symptoms are present, along with at least four other symptoms, some of which should be severe. The episode should last for a minimum of two weeks, but an early diagnosis may be appropriate if the symptoms are particularly severe. Individuals may also experience psychotic symptoms and show severe distress or agitation.
Screening and Assessment of Depression
Depression is a common mental health condition that affects many people worldwide. Screening and assessment are important steps in identifying and managing depression. The screening process involves asking two simple questions to determine if a person is experiencing symptoms of depression. If the answer is yes to either question, a more in-depth assessment is necessary.
Assessment tools such as the Hospital Anxiety and Depression (HAD) scale and the Patient Health Questionnaire (PHQ-9) are commonly used to assess the severity of depression. The HAD scale consists of 14 questions, seven for anxiety and seven for depression. Each item is scored from 0-3, producing a score out of 21 for both anxiety and depression. The PHQ-9 asks patients about nine different problems they may have experienced in the last two weeks, which can then be scored from 0-3. This tool also includes questions about thoughts of self-harm.
The DSM-IV criteria are used by NICE to grade depression. This criteria includes nine different symptoms, such as depressed mood, diminished interest or pleasure in activities, and feelings of worthlessness or guilt. The severity of depression can range from subthreshold depressive symptoms to severe depression with or without psychotic symptoms.
In conclusion, screening and assessment are crucial steps in identifying and managing depression. By using tools such as the HAD scale and PHQ-9, healthcare professionals can accurately assess the severity of depression and provide appropriate treatment.

Which one of the following is not a fundamental aspect of clinical governance?
Your Answer: Health promotion
Explanation:Although health promotion is crucial, it falls outside the scope of clinical governance.
Understanding Clinical Governance
Clinical governance is a system that holds NHS organizations accountable for improving the quality of their services and ensuring high standards of care. It creates an environment that fosters clinical excellence and continuous improvement. This system is made up of several components, including education and training, clinical audit, clinical effectiveness, research and development, risk management, and openness. Each of these elements plays a crucial role in ensuring that healthcare providers deliver the best possible care to patients. By implementing clinical governance, NHS organizations can identify areas for improvement, measure their progress, and make changes that benefit patients and staff alike. With a focus on quality and safety, clinical governance is an essential part of modern healthcare.

A 60-year-old man is brought to his General Practitioner (GP) by his son. The son complains that his father's personality has changed completely over the past year. Even at his best, he is forgetful and ‘switched off’. At worst, he is drowsy and unresponsive. He is particularly concerned that his father has been claiming to 'see things that aren't really there'. Over the past few weeks, he has also been tripping a lot on the carpet and is no longer safe on the stairs going to his bedroom unaccompanied. The GP gave the patient a small dose of a neuroleptic which 'made things a million times worse'.
On examination, he has an inexpressive face, with a mild resting tremor and some axial rigidity. There is no other focal neurology. On mini-mental state examination, he scores 20/30.
What is the most likely primary brain pathology?
Your Answer: Lewy bodies
Explanation:Understanding Lewy Body Dementia: A Comparison with Other Neurological Conditions
Lewy body dementia is a neurological condition characterized by extrapyramidal signs, visual hallucinations, and a variable symptom profile. Patients with this condition are also highly sensitive to the anticholinergic side-effects of neuroleptics. The presence of eosinophilic inclusions bodies called Lewy bodies in the limbic areas of the brain is a hallmark of this condition.
It is important to differentiate Lewy body dementia from other neurological conditions that may present with similar symptoms. Normal brain is an unlikely diagnosis given the neurological symptoms seen in patients with Lewy body dementia. Multiple infarcts in the grey matter, on the other hand, typically have a stepwise course with an acute onset and patchy cognitive impairment. Neurofibrillary tangles are characteristic of Alzheimer’s disease, which presents with early impairment of memory that evolves into more general deficits in concentration and attention. Finally, Pick bodies are associated with fronto-temporal dementias and tend to involve disinhibition as an early feature.
In summary, understanding the unique features of Lewy body dementia and its differences from other neurological conditions is crucial for accurate diagnosis and appropriate management of patients.

A 55-year-old has just been diagnosed with hypertension and you have commenced treatment with an ACE inhibitor (ACE-I).
As per NICE guidelines, what are the monitoring obligations after initiating an ACE-I?Your Answer: Renal function and serum electrolytes 2-3 weeks after starting treatment
Correct Answer: No monitoring required
Explanation:Monitoring Recommendations for ACE-I Treatment
After initiating ACE-I treatment, it is recommended by NICE to monitor renal function and serum electrolytes within 1-2 weeks. However, if the patient is at a higher risk of hyperkalaemia or deteriorating renal function, such as those with Peripheral Vascular Disease, diabetes, or the elderly, it is suggested to check within 1 week. Blood pressure should be checked 4 weeks after each dose titration. After the initial monitoring, renal function and serum electrolytes only need to be checked annually unless there are abnormal blood test results or clinical judgement indicates a need for more frequent testing. By following these monitoring recommendations, healthcare professionals can ensure the safety and efficacy of ACE-I treatment for their patients.

A 26-year-old female patient visits her general practitioner with a concern about excessive hair growth on her arms. She has a slim build and olive skin with dark brown hair. The patient shaves the hair to remove it. Her menstrual cycles are regular, occurring every 33 days, and she reports no heavy bleeding or pain. What is the probable diagnosis?
Your Answer: Genetic phenotype
Explanation:Excessive hair growth on the arms may be noticeable in this woman due to her genetic makeup, as she has olive skin and dark hair. However, hirsutism, which is characterized by excessive hair growth on the face and body, is often associated with polycystic ovarian syndrome. Although her menstrual cycle is regular at 33 days, it is important to note that a normal cycle can range from 24 to 35 days. A cycle variation of 8 days or more is considered moderately irregular, while a variation of 21 days or more is considered very irregular. Additionally, this patient has light periods and a slim physique.
Understanding Hirsutism and Hypertrichosis
Hirsutism is a term used to describe excessive hair growth in women that is dependent on androgens, while hypertrichosis refers to hair growth that is not androgen-dependent. Polycystic ovarian syndrome is the most common cause of hirsutism, but other factors such as Cushing’s syndrome, obesity, and certain medications can also contribute to this condition. To assess hirsutism, the Ferriman-Gallwey scoring system is often used, which assigns scores to nine different body areas. Management of hirsutism may involve weight loss, cosmetic techniques, or the use of oral contraceptive pills or topical medications.
Hypertrichosis, on the other hand, can be caused by a variety of factors such as certain medications, congenital conditions, and even anorexia nervosa. It is important to identify the underlying cause of excessive hair growth in order to determine the most appropriate treatment approach. By understanding the differences between hirsutism and hypertrichosis, individuals can better manage these conditions and improve their quality of life.

A 27-year-old Muslim woman who works night shifts visits your clinic. What vitamin or mineral deficiencies should she be cautious of?
Your Answer: Vitamin D
Correct Answer: Vitamin B12
Explanation:Vitamin D Deficiency and Risk Factors
People who have limited exposure to sunlight, such as those who cover their skin for cultural reasons, are at risk of vitamin D deficiency. This is also true for individuals who work night shifts and sleep during the day, as well as those who are housebound or have darker skin. Pregnant women in these groups are especially vulnerable and should be offered supplements.
While a varied diet can help prevent deficiencies in other vitamins and minerals, it may not be enough to prevent vitamin D deficiency. This is because only a small percentage of vitamin D is obtained from diet, with the majority coming from sunlight exposure on the skin. Therefore, it is important for individuals in at-risk groups to consider taking supplements to ensure adequate vitamin D levels.

A 72-year-old man seeks advice regarding his upcoming trip to Australia to visit his daughter who has emigrated. He is concerned about the risk of deep vein thrombosis as he was diagnosed with this condition approximately 40 years ago during his wife's second pregnancy. However, there are no other significant risk factors for venous thromboembolism. What is the best advice to provide?
Your Answer: Wear compression stockings
Explanation:Considering her age, previous DVT, and long haul destination, this woman is at a higher risk of travel related thrombosis. Therefore, the most suitable recommendation for her would be to wear compression stockings.
Travel-Related Thrombosis and Guidelines for Prevention
Long-haul air travel has been associated with an increased risk of venous thromboembolism (VTE), commonly known as economy class syndrome. However, there is no universal agreement on how to advise patients regarding VTE prevention during travel. The British Committee for Standards in Haematology, SIGN, and Clinical Knowledge Summaries have all produced guidelines, but they differ in their recommendations.
The most recent CKS guidelines suggest a risk-based approach. Patients with no major risk factors for VTE do not require special measures. However, those with major risk factors should consider wearing anti-embolism stockings, which can be bought or prescribed. In cases of very high risk, such as a long-haul flight following recent major surgery, delaying the flight or seeking specialist advice regarding the use of low-molecular weight heparin may be necessary.
It is important to note that all guidelines agree that there is no role for aspirin in VTE prevention for low, medium, or high-risk patients. A 2001 study in the New England Journal of Medicine showed that the risk of pulmonary embolism increases with travel distance, with 4.8 cases per million for travel over 10,000 km. While the Civil Aviation Authority doesn’t provide specific guidance on VTE prevention, healthcare providers can use these guidelines to help patients make informed decisions about their travel plans.
