Common Psychiatric Medications and Their Side-Effects

Haloperidol: A typical antipsychotic drug that can cause extrapyramidal side-effects (EPSEs), including acute dystonic reactions. Treatment is with anticholinergic drugs or benzodiazepines.

Clozapine: An atypical antipsychotic mainly used in treatment-resistant schizophrenia. Common side-effects include sedation, constipation, hypersalivation, weight gain, and metabolic syndrome. Rare but important side-effects include agranulocytosis, arrhythmias, and myocarditis. EPSEs are possible but rare.

Diazepam: A benzodiazepine used in anxiety, insomnia, seizures, and muscle spasms. Side-effects include sedation, muscle weakness, drowsiness, and confusion. EPSEs are not a recognised side-effect and may improve with the use of benzodiazepines.

Lithium: A mood stabiliser used in the treatment of mania, depression, and bipolar disorder. Side-effects include gastrointestinal disturbances, tremor, polydipsia, polyuria, and electrolyte disturbances. Lithium-induced hypothyroidism is common. EPSEs are not a side-effect of lithium.

Olanzapine: An atypical antipsychotic used in the treatment of schizophrenia and acute mania. Common side-effects include sedation, weight gain, and metabolic symptoms. EPSEs can occur but are not a typical side-effect of olanzapine.

The ECG changes observed in this scenario are most likely due to hypokalaemia. The patient’s electrolyte balance has been disrupted by vomiting and loose stools, resulting in a depletion of potassium that should be rectified through intravenous replacement. While hypocalcaemia and hypothermia can also cause U waves, they are less probable in this case. Non-ischaemic ST elevation changes may be caused by hyponatraemia. QT prolongation is a common effect of tricyclic antidepressant toxicity.

ECG Features of Hypokalaemia

Hypokalaemia is a condition characterized by low levels of potassium in the blood. This condition can be detected through an electrocardiogram (ECG) which shows specific features. The ECG features of hypokalaemia include U waves, small or absent T waves, prolonged PR interval, ST depression, and long QT. The U waves are particularly noticeable and are accompanied by a borderline PR interval.

To remember these features, one registered user suggests the following rhyme: In Hypokalaemia, U have no Pot and no T, but a long PR and a long QT. It is important to detect hypokalaemia early as it can lead to serious complications such as cardiac arrhythmias and even cardiac arrest. Therefore, regular monitoring of potassium levels and ECGs is crucial for individuals at risk of hypokalaemia.

Monitoring Statin Therapy: Recommended Blood Tests and Timing

Statin therapy is a common treatment for patients with high cholesterol levels, both for primary and secondary prevention of cardiovascular disease. However, regular monitoring is necessary to ensure the treatment is effective and safe. Here are some recommended blood tests and their timing for monitoring statin therapy:

Recommended Blood Tests and Timing for Monitoring Statin Therapy

Check LFTs and lipid profiles at 3 months

Within three months of starting high-intensity statin treatment, it is recommended to measure total cholesterol, HDL-cholesterol, and non-HDL cholesterol. The aim is to achieve a >40% reduction in non-HDL-cholesterol. LFTs should also be checked at this time and again at 12 months, unless clinically indicated.

Check LFTs and lipid profiles at 12 months

Both LFTs and the lipid profile should be checked at 12 months, but it is important to assess whether a suitable cholesterol level reduction has been achieved earlier in the process. This allows for discussion of adherence to medication, diet, and lifestyle measures, and consideration of increasing the dose.

Check LFTs at 1 week

Checking LFTs within a week of starting treatment is not necessary, as any liver abnormalities would be unlikely to develop so soon without the patient experiencing symptoms of acute liver disease.

Check the lipid profiles at 1 month

It takes approximately 6-8 weeks for a stable result in lipid reduction to be seen after starting a statin, so checking the lipid profile at 1 month is not appropriate.

Check TFTs at 3 months

There is no need to check thyroid function tests during statin therapy for monitoring purposes. However, patients with other conditions that justify TFTs should have them done as clinically appropriate.

Regular monitoring of statin therapy through blood tests is crucial for ensuring the treatment is effective and safe for patients with high cholesterol levels.

In patients aged 75 years or older who have experienced a fragility fracture, alendronate should be initiated without delay, even in the absence of a DEXA scan. This patient meets the NICE criteria for bisphosphonate treatment, and while a calcium-rich diet and supplementation may be helpful, they are not sufficient for managing osteoporosis. Zoledronic acid may be considered if the patient cannot tolerate bisphosphonates, but it should not be the first-line treatment.

Managing Osteoporosis in Patients with Fragility Fracture

The management of patients with fragility fractures depends on their age. For patients aged 75 years and above, they are presumed to have underlying osteoporosis and should be started on first-line therapy, which is an oral bisphosphonate, without the need for a DEXA scan. However, the 2014 NOGG guidelines suggest that treatment should be started in all women over the age of 50 years who’ve had a fragility fracture, although BMD measurement may sometimes be appropriate, particularly in younger postmenopausal women.

On the other hand, for patients below 75 years old, a DEXA scan should be arranged to determine their ongoing fracture risk. The results of the scan can be entered into a FRAX assessment, along with the fact that they’ve had a fracture, to determine the appropriate management plan. For instance, if a 79-year-old woman sustains a Colles’ fracture, she is presumed to have osteoporosis and should be started on oral alendronate 70mg once weekly without a DEXA scan.

In summary, managing osteoporosis in patients with fragility fractures requires age consideration and appropriate assessment to determine the best management plan.

Treatment options for stroke prevention in atrial fibrillation patients: Understanding CHADS-VASc score

Atrial fibrillation (AF) patients with a CHADS-VASc score of 3 or higher require treatment with either warfarin or a novel oral anticoagulant (NOAC) to prevent stroke. Aspirin, clopidogrel, low-molecular-weight heparin, and strict dietary modification are not recommended for stroke prevention in AF patients.

The CHADS-VASc score is used to calculate the risk of stroke in AF patients. The score includes factors such as congestive cardiac failure, hypertension, age, diabetes mellitus, previous stroke or transient ischaemic attack, vascular disease, and sex category. Men with a score of 2 or higher are considered to be at high risk of stroke and should start treatment with warfarin or a NOAC. Men with a score of 1 are considered to be at moderate risk and should consider anticoagulation. Women aged <65 years with no other risk factors are considered to be at low risk and do not require anticoagulation. Clopidogrel is an oral antiplatelet agent used in the prevention of atherosclerotic events in patients with coronary artery disease, peripheral arterial disease, and cerebrovascular disease. It is not recommended for stroke prevention in AF patients. Strict dietary modification is not an appropriate treatment for AF and essential hypertension. Low molecular weight heparins (LMWHs) are not used in the management of AF. They are commonly used in the prevention and treatment of venous thromboembolism, unstable angina, and acute myocardial infarction.

Neonatal Blood Spot Screening: Identifying Potential Health Risks in Newborns

Neonatal blood spot screening, also known as the Guthrie test or heel-prick test, is a routine procedure performed on newborns between 5-9 days of life. The test involves collecting a small sample of blood from the baby’s heel and analyzing it for potential health risks. Currently, there are nine conditions that are screened for, including congenital hypothyroidism, cystic fibrosis, sickle cell disease, phenylketonuria, medium chain acyl-CoA dehydrogenase deficiency (MCADD), maple syrup urine disease (MSUD), isovaleric acidaemia (IVA), glutaric aciduria type 1 (GA1), and homocystinuria (pyridoxine unresponsive) (HCU).

What is the effectiveness of secondary prevention measures for women with pre-eclampsia? A-level research has shown that low-dose aspirin, when started at 12-14 weeks’ gestation, is more effective than a placebo in reducing the occurrence of pre-eclampsia in high-risk women. This treatment also reduces perinatal mortality and the risk of babies being born small for gestational age. While low molecular weight heparin may reduce placental insufficiency in pre-eclampsia, there is currently a lack of long-term safety studies. Labetalol and methyldopa are commonly used antihypertensive drugs for acute management of pre-eclampsia, but they are not given prophylactically and do not reduce intrauterine growth retardation. Unfractionated heparin has also not been proven to prevent the development of uteroplacental insufficiency.

Hypertension during pregnancy is a common occurrence that requires careful management. In normal pregnancies, blood pressure tends to decrease in the first trimester and then gradually increase to pre-pregnancy levels by term. However, in cases of hypertension during pregnancy, the systolic blood pressure is usually above 140 mmHg or the diastolic blood pressure is above 90 mmHg. Additionally, an increase of more than 30 mmHg systolic or 15 mmHg diastolic from the initial readings may also indicate hypertension.

There are three categories of hypertension during pregnancy: pre-existing hypertension, pregnancy-induced hypertension (PIH), and pre-eclampsia. Pre-existing hypertension refers to a history of hypertension before pregnancy or elevated blood pressure before 20 weeks gestation. PIH occurs in the second half of pregnancy and resolves after birth. Pre-eclampsia is characterized by hypertension and proteinuria, and may also involve edema.

The management of hypertension during pregnancy involves the use of antihypertensive medications such as labetalol, nifedipine, and hydralazine. In cases of pre-existing hypertension, ACE inhibitors and angiotensin II receptor blockers should be stopped immediately and alternative medications should be prescribed. Women who are at high risk of developing pre-eclampsia should take aspirin from 12 weeks until the birth of the baby. It is important to carefully monitor blood pressure and proteinuria levels during pregnancy to ensure the health of both the mother and the baby.

Differential Diagnosis for a Patient with Hypocellular Bone Marrow and Thrombocytopenia

Aplastic anaemia is a condition characterized by bone marrow failure, resulting in peripheral pancytopenia and bone-marrow hypoplasia. This leads to a deficiency in the production of red blood cells, causing anaemia, and a reduced production of white blood cells, leading to immunodeficiency. Patients may experience symptoms such as shortness of breath, lethargy, pallor, mouth ulcers, and increased frequency of infections. The reduced production of platelets causes easy bruising.

Idiopathic thrombocytopenic purpura (ITP) is a condition characterized by an isolated reduction in platelets with normal bone marrow, in the absence of another identifiable cause. Patients may present with abnormal bleeding and bruising, petechiae, and purpura.

Haemophilia A is an X-linked-recessive condition causing a deficiency in clotting factor VIII, leading to easy bruising, prolonged bleeding after injury, or spontaneous bleeding in severe cases.

Infectious mononucleosis is the result of Epstein–Barr virus infection, characterized by fever, pharyngitis, lymphadenopathy, and a macular or maculopapular rash.

Autoimmune neutropenia is associated with opportunistic infections, most commonly otitis media. However, this condition would not account for the thrombocytopenia observed in this patient.

Sheehan’s syndrome, also known as postpartum hypopituitarism, is characterized by a decrease in pituitary gland function caused by ischemic necrosis resulting from hypovolemic shock after childbirth. The symptoms can be diverse and may take several years to manifest due to the pituitary damage. The patient’s presentation of amenorrhea, lactation difficulties, and hypothyroidism suggests pituitary dysfunction, which can be attributed to her complicated delivery, leading to a diagnosis of Sheehan’s syndrome.

Understanding Amenorrhoea: Causes, Investigations, and Management

Amenorrhoea is a condition characterized by the absence of menstrual periods in women. It can be classified into two types: primary and secondary. Primary amenorrhoea occurs when menstruation fails to start by the age of 15 in girls with normal secondary sexual characteristics or by the age of 13 in girls with no secondary sexual characteristics. On the other hand, secondary amenorrhoea is the cessation of menstruation for 3-6 months in women with previously normal and regular menses or 6-12 months in women with previous oligomenorrhoea.

There are various causes of amenorrhoea, including gonadal dysgenesis, testicular feminization, congenital malformations of the genital tract, functional hypothalamic amenorrhoea, congenital adrenal hyperplasia, imperforate hymen, hypothalamic amenorrhoea, polycystic ovarian syndrome, hyperprolactinemia, premature ovarian failure, Sheehan’s syndrome, Asherman’s syndrome, and thyrotoxicosis. To determine the underlying cause of amenorrhoea, initial investigations such as full blood count, urea & electrolytes, coeliac screen, thyroid function tests, gonadotrophins, prolactin, and androgen levels are necessary.

The management of amenorrhoea depends on the underlying cause. For primary amenorrhoea, it is important to investigate and treat any underlying cause. Women with primary ovarian insufficiency due to gonadal dysgenesis may benefit from hormone replacement therapy to prevent osteoporosis. For secondary amenorrhoea, it is important to exclude pregnancy, lactation, and menopause in women 40 years of age or older and treat the underlying cause accordingly. It is important to note that hypothyroidism may also cause amenorrhoea.

Trochanteric bursitis is no longer the preferred term and has been replaced by greater trochanteric pain syndrome. The x-ray reveals joint space narrowing, which is a common occurrence. Osteoarthritis is unlikely due to the palpable pain and short duration of symptoms.

Causes of Hip Pain in Adults

Hip pain in adults can be caused by a variety of conditions. Osteoarthritis is a common cause, with pain that worsens with exercise and improves with rest. Reduced internal rotation is often the first sign, and risk factors include age, obesity, and previous joint problems. Inflammatory arthritis can also cause hip pain, with pain typically worse in the morning and accompanied by systemic features and raised inflammatory markers. Referred lumbar spine pain may be caused by femoral nerve compression, which can be tested with a positive femoral nerve stretch test. Greater trochanteric pain syndrome, or trochanteric bursitis, is caused by repeated movement of the iliotibial band and is most common in women aged 50-70 years. Meralgia paraesthetica is caused by compression of the lateral cutaneous nerve of the thigh and typically presents as a burning sensation over the antero-lateral aspect of the thigh. Avascular necrosis may have gradual or sudden onset and may follow high dose steroid therapy or previous hip fracture or dislocation. Pubic symphysis dysfunction is common in pregnancy and presents with pain over the pubic symphysis with radiation to the groins and medial aspects of the thighs, often with a waddling gait. Transient idiopathic osteoporosis is an uncommon condition sometimes seen in the third trimester of pregnancy, with groin pain and limited range of movement in the hip, and patients may be unable to weight bear. ESR may be elevated in this condition.

If a baby was in a breech presentation, it is important to ensure that they have been referred for screening for developmental dysplasia of the hip (DDH) as it is a risk factor for this condition. The Department of Health recommends that all babies who were breech at any point from 36 weeks (even if not breech at birth), babies born before 36 weeks who were in a breech presentation, and all babies with a first degree relative who had a hip problem in early life, should undergo ultrasound screening for hip dysplasia. If one twin was breech, both should be screened. Some hospitals also refer babies with other conditions such as oligohydramnios, high birth weight, torticollis, congenital talipes calcaneovalgus, and metatarsus adductus for screening. For more information on screening for DDH, please refer to the link provided.

Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be bilateral in 20% of cases. Screening for DDH is recommended for infants with certain risk factors, and all infants are screened using the Barlow and Ortolani tests at the newborn and six-week baby check. Clinical examination includes testing for leg length symmetry, restricted hip abduction, and knee level when hips and knees are flexed. Ultrasound is used to confirm the diagnosis if clinically suspected, but x-ray is the first line investigation for infants over 4.5 months. Management includes the use of a Pavlik harness for children under 4-5 months and surgery for older children with unstable hips.

Aspirin irreversibly inhibits both COX 1 and COX 2, preventing the conversion of arachidonic acid into prostaglandin, prostacyclin, and thromboxane. Thromboxane A2 is responsible for platelet aggregation and vasoconstriction. In cases of acute coronary syndrome, high doses of aspirin are administered to prevent the enlargement of the coronary thrombus.

The Mechanism and Guidelines for Aspirin Use in Cardiovascular Disease

Aspirin is a medication that works by blocking the action of cyclooxygenase-1 and 2, which are responsible for the synthesis of prostaglandin, prostacyclin, and thromboxane. By inhibiting the formation of thromboxane A2 in platelets, aspirin reduces their ability to aggregate, making it a widely used medication in cardiovascular disease. However, recent trials have cast doubt on the use of aspirin in primary prevention of cardiovascular disease, leading to changes in guidelines. Aspirin is now recommended as a first-line treatment for patients with ischaemic heart disease, but it should not be used in children under 16 due to the risk of Reye’s syndrome. The medication can also potentiate the effects of oral hypoglycaemics, warfarin, and steroids.

The Medicines and Healthcare products Regulatory Agency (MHRA) issued a drug safety update in January 2010, reminding prescribers that aspirin is not licensed for primary prevention. NICE now recommends clopidogrel as a first-line treatment following an ischaemic stroke and for peripheral arterial disease. However, the situation is more complex for TIAs, with recent Royal College of Physician (RCP) guidelines supporting the use of clopidogrel, while older NICE guidelines still recommend aspirin + dipyridamole – a position the RCP state is ‘illogical’. Despite these changes, aspirin remains an important medication in the treatment of cardiovascular disease, and its use should be carefully considered based on individual patient needs and risk factors.

Treatment Options for Atrial Fibrillation: A Comprehensive Guide

Atrial fibrillation (AF) is a common cardiac arrhythmia that requires prompt and appropriate management to prevent complications. Here are some treatment options for AF:

Rate Control: This is recommended for patients who have had AF for more than 48 hours. Beta-blockers are the first-line treatment unless there is a contraindication such as asthma. Calcium channel blockers can also be used.

Digoxin: This drug can be used as rate control if the patient cannot have beta-blockers or calcium channel blockers. However, it should only be used as a third-line treatment or as an adjunct because it has been shown to increase mortality. It is also only effective in sedentary patients.

DC Cardioversion: This can be used to treat new-onset AF if the patient has had it for less than 48 hours. It can also be considered in patients who have had it for longer than that, once they have been on stable anticoagulation for at least 3 weeks.

Flecainide: This is a class Ic antiarrhythmic drug that can be used as chemical cardioversion in new AF (<48 hours) or if a patient has been anticoagulated for >3 weeks.

Rhythm Control: Nice guidelines advise that rhythm control can be used if AF onset was <48 hours ago, but should be avoided if longer ago because it can increase the risk of stroke from an atrial thrombus. In longer cases, rate control should be used, which is with beta-blockers or rate-limiting calcium channel blockers. Digoxin can be used third line or as an adjunct. In conclusion, the appropriate treatment for AF depends on the duration of the arrhythmia, the patient’s comorbidities, and other factors. It is important to consult with a healthcare professional to determine the best course of action.

The most appropriate investigation to arrange for a patient presenting with symptoms suggestive of a urinary tract infection or pyelonephritis is urinary microscopy and culture. It is important to obtain a sample before starting empirical antibiotics to guide subsequent antibiotic choice if the initial course is ineffective. While genital swabs may be useful if there is a history of sexually transmitted infection, they are not as important as urine culture in this situation. Cystoscopy and ultrasound scans of the abdomen may be useful in other situations, but are not urgently indicated in this case. Similarly, a CTKUB would not be useful in investigating the cause of the infection, which can be determined through urine culture.

The most common cause of hypothyroidism is autoimmune thyroiditis, specifically Hashimoto’s thyroiditis, which is often associated with other autoimmune diseases. This is indicated by a presentation and blood test showing hypothyroidism with a raised TSH, suggesting a failure of the thyroid gland to respond to pituitary stimulation or a primary hypothyroidism. While iodine deficiency is the main cause of hypothyroidism worldwide, it is rare in the UK. Papillary thyroid cancer does not affect thyroid function, as the cancer cells do not secrete thyroxine. Although De Quervain’s can cause a primary hypothyroidism with similar symptoms, it is much less common than Hashimoto’s and therefore an incorrect answer.

Understanding Hashimoto’s Thyroiditis

Hashimoto’s thyroiditis is a chronic autoimmune disorder that affects the thyroid gland. It is more common in women and is typically associated with hypothyroidism, although there may be a temporary period of thyrotoxicosis during the acute phase. The condition is characterized by features of hypothyroidism, such as a firm, non-tender goitre, and the presence of anti-thyroid peroxidase (TPO) and anti-thyroglobulin (Tg) antibodies.

Hashimoto’s thyroiditis is often associated with other autoimmune conditions, including coeliac disease, type 1 diabetes mellitus, and vitiligo. Additionally, there is an increased risk of developing MALT lymphoma with this condition. It is important to note that many causes of hypothyroidism may have an initial thyrotoxic phase, as shown in the Venn diagram. Understanding the features and associations of Hashimoto’s thyroiditis can aid in its diagnosis and management.

Antibiotics for Dog Bite Infections: Recommended and Not Recommended Options

Dog bites can lead to infections caused by various micro-organisms, including anaerobic mouth flora and bacteria. Co-amoxiclav, a combination of amoxicillin and clavulanic acid, is the recommended antibiotic for dog bite-related infections, as it is effective against the most likely organisms. Fluconazole, an antifungal agent, is not indicated for such infections, as fungal micro-organisms in dogs usually cause only superficial skin rashes. Metronidazole, although effective against anaerobic bacteria, is not recommended for dog bite-related infections, except for patients allergic to penicillin. Aciclovir is not used for dog bite-related infections, as it is restricted to treating varicella-zoster and herpes zoster. Flucloxacillin, although recommended for skin infections, is not active against anaerobic bacteria and is not recommended for dog bite-related infections.

Currently, there is no dependable screening test for detecting ovarian cancer in its early stages. However, women, especially those over 50 years old, who experience persistent symptoms such as abdominal bloating, early satiety, loss of appetite, pelvic or abdominal pain, and increased urinary urgency or frequency should be suspected of having ovarian cancer and should undergo further tests.

Ovarian cancer is a common malignancy in women, ranking fifth in frequency. It is most commonly diagnosed in women over the age of 60 and has a poor prognosis due to late detection. The majority of ovarian cancers, around 90%, are of epithelial origin, with serous carcinomas accounting for 70-80% of cases. Interestingly, recent research suggests that many ovarian cancers may actually originate in the distal end of the fallopian tube. Risk factors for ovarian cancer include a family history of BRCA1 or BRCA2 gene mutations, early menarche, late menopause, and nulliparity.

Clinical features of ovarian cancer are often vague and can include abdominal distension and bloating, abdominal and pelvic pain, urinary symptoms such as urgency, early satiety, and diarrhea. The initial diagnostic test recommended by NICE is a CA125 blood test, although this can also be elevated in other conditions such as endometriosis and benign ovarian cysts. If the CA125 level is raised, an urgent ultrasound scan of the abdomen and pelvis should be ordered. However, a CA125 test should not be used for screening asymptomatic women. Diagnosis of ovarian cancer is difficult and usually requires a diagnostic laparotomy.

Management of ovarian cancer typically involves a combination of surgery and platinum-based chemotherapy. Unfortunately, 80% of women have advanced disease at the time of diagnosis, leading to a 5-year survival rate of only 46%. It was previously thought that infertility treatment increased the risk of ovarian cancer due to increased ovulation, but recent evidence suggests that this is not a significant factor. In fact, the combined oral contraceptive pill and multiple pregnancies have been shown to reduce the risk of ovarian cancer by reducing the number of ovulations.

The use of combined oral contraceptive pill is associated with a reduced risk of endometrial cancer.

Endometrial cancer is a type of cancer that is commonly found in women who have gone through menopause, but it can also occur in around 25% of cases before menopause. The prognosis for this type of cancer is usually good due to early detection. There are several risk factors associated with endometrial cancer, including obesity, nulliparity, early menarche, late menopause, unopposed estrogen, diabetes mellitus, tamoxifen, polycystic ovarian syndrome, and hereditary non-polyposis colorectal carcinoma. Postmenopausal bleeding is the most common symptom of endometrial cancer, which is usually slight and intermittent initially before becoming more heavy. Pain is not common and typically signifies extensive disease, while vaginal discharge is unusual.

When investigating endometrial cancer, women who are 55 years or older and present with postmenopausal bleeding should be referred using the suspected cancer pathway. The first-line investigation is trans-vaginal ultrasound, which has a high negative predictive value for a normal endometrial thickness (< 4 mm). Hysteroscopy with endometrial biopsy is also commonly used for investigation. The management of localized disease involves total abdominal hysterectomy with bilateral salpingo-oophorectomy, while patients with high-risk disease may have postoperative radiotherapy. Progestogen therapy is sometimes used in frail elderly women who are not considered suitable for surgery. It is important to note that the combined oral contraceptive pill and smoking are protective against endometrial cancer.

Management of Dyspepsia and Referral for Possible Cancer

Dyspepsia is a common symptom that can be caused by various factors, including medication and lifestyle choices. However, it can also be a sign of underlying conditions such as stomach or oesophageal cancer. The 2015 NICE guidelines provide updated advice on when urgent referral for endoscopy is necessary. Patients with dysphagia or an upper abdominal mass consistent with stomach cancer should be referred urgently. Patients aged 55 years or older with weight loss and upper abdominal pain, reflux, or dyspepsia should also be referred urgently. Non-urgent referrals include patients with haematemesis or those with treatment-resistant dyspepsia, upper abdominal pain with low haemoglobin levels, or raised platelet count with other symptoms.

For patients with undiagnosed dyspepsia, a step-wise approach is recommended. First, medications should be reviewed for possible causes. Lifestyle advice should also be given. If symptoms persist, a trial of full-dose proton pump inhibitor for one month or a ‘test and treat’ approach for H. pylori can be tried. If symptoms persist after either approach, the alternative should be attempted. Testing for H. pylori infection can be done using a carbon-13 urea breath test, stool antigen test, or laboratory-based serology. If symptoms resolve following test and treat, there is no need to check for H. pylori eradication. However, if repeat testing is required, a carbon-13 urea breath test should be used.

Men with BRCA2 mutation are at a higher risk of developing prostate cancer, while both men and women with this mutation have a significantly increased risk of developing breast cancer. Additionally, women with BRCA2 mutation are more likely to develop ovarian cancer. Although young-onset colorectal cancer is linked to BRCA1 mutation, there is no such association observed in individuals with BRCA2 mutation.

Li-Fraumeni Syndrome is caused by mutations in the p53 gene and increases the risk of developing sarcomas and leukemias. BRCA 1 and 2 mutations increase the risk of breast and ovarian cancer, and BRCA 2 is also associated with prostate cancer in men. Lynch Syndrome increases the risk of colon and endometrial cancer, and can be identified using the Amsterdam criteria. Gardner’s Syndrome is a familial colorectal polyposis that can lead to colectomy to reduce the risk of colorectal cancer.

According to the latest NICE guidelines, a CT head scan is necessary for this patient as their GCS remains below 15 after 2 hours.

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 with no 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.

Admission to the paediatric ward is necessary when a child presents with audible stridor at rest, which is a clear indication of croup. This condition is characterized by a barking cough, mild fever, and coryzal symptoms, and in moderate cases, suprasternal wall retraction may be observed. Discharging the patient with dexamethasone or antibiotics is not appropriate, as stridor at rest requires further observation. A single dose of oral dexamethasone should be administered to all children with croup, regardless of severity. Referral to ENT is not urgent and not necessary in this case.

Understanding Croup: A Respiratory Infection in Infants and Toddlers

Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.

The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.

Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.

Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

Scarlet fever is a condition caused by erythrogenic toxins produced by Group A haemolytic streptococci, usually Streptococcus pyogenes. It is more prevalent in children aged 2-6 years, with the highest incidence at 4 years. The disease spreads through respiratory droplets or direct contact with nose and throat discharges, especially during sneezing and coughing. The incubation period is 2-4 days, and symptoms include fever, malaise, headache, nausea/vomiting, sore throat, ‘strawberry’ tongue, and a rash that appears first on the torso and spares the palms and soles. The rash has a rough ‘sandpaper’ texture and desquamination occurs later in the course of the illness, particularly around the fingers and toes.

To diagnose scarlet fever, a throat swab is usually taken, but antibiotic treatment should be initiated immediately, rather than waiting for the results. Management involves administering oral penicillin V for ten days, while patients with a penicillin allergy should be given azithromycin. Children can return to school 24 hours after commencing antibiotics, and scarlet fever is a notifiable disease. Although usually a mild illness, scarlet fever may be complicated by otitis media, rheumatic fever, acute glomerulonephritis, or rare invasive complications such as bacteraemia, meningitis, or necrotizing fasciitis, which may present acutely with life-threatening illness.

Bacterial Causes of Malignant Otitis Externa

Malignant otitis externa is a serious infection that primarily affects patients with uncontrolled diabetes. The infection can spread to the temporal bone, causing osteomyelitis, cranial nerve palsies, and potentially central nervous system infection. The most common causative agent for this condition is Pseudomonas aeruginosa.

Haemophilus influenzae is a Gram-negative coccobacillus that can cause various infections, including cellulitis, but it is not consistent with the symptoms of malignant otitis externa.

Staphylococcus aureus, a commensal bacterium, can cause skin and soft-tissue infections, including malignant otitis externa. The characteristic signs and symptoms presented by the patient are more typical of this condition than cellulitis.

Streptococcus pneumoniae is a common cause of pneumonia and meningitis, but it is not consistent with the symptoms of malignant otitis externa.

Listeria monocytogenes is a rare cause of infection that primarily affects newborns, the elderly, and immunocompromised patients. It is not consistent with the clinical scenario provided.

The presence of calcitonin in the blood can indicate the presence of medullary thyroid cancer, as this type of cancer originates from the parafollicular cells that produce calcitonin. Therefore, calcitonin is considered a tumor marker for medullary thyroid cancer.

Understanding Tumour Markers

Tumour markers are substances that can be found in the blood, urine, or tissues of people with cancer. They are often used to help diagnose and monitor cancer, as well as to determine the effectiveness of treatment. Tumour markers can be divided into different categories, including monoclonal antibodies against carbohydrate or glycoprotein tumour antigens, tumour antigens, enzymes, and hormones.

Monoclonal antibodies are used to target specific tumour antigens, which are proteins or other molecules that are found on the surface of cancer cells. Some common tumour markers include CA 125 for ovarian cancer, CA 19-9 for pancreatic cancer, and CA 15-3 for breast cancer. However, it is important to note that tumour markers usually have a low specificity, meaning that they can also be found in people without cancer.

Tumour antigens are proteins that are produced by cancer cells and can be detected in the blood or tissues of people with cancer. Some examples of tumour antigens include prostate specific antigen (PSA) for prostatic carcinoma, alpha-feto protein (AFP) for hepatocellular carcinoma and teratoma, and carcinoembryonic antigen (CEA) for colorectal cancer.

Enzymes and hormones can also be used as tumour markers. For example, alkaline phosphatase and neurone specific enolase are enzymes that can be elevated in people with cancer, while hormones such as calcitonin and ADH can be used to detect certain types of cancer.

In summary, tumour markers are an important tool in the diagnosis and monitoring of cancer. However, they should be used in conjunction with other diagnostic tests and imaging studies, as they are not always specific to cancer and can also be elevated in people without cancer.

Left bundle branch block is typically indicative of underlying ischaemic or structural heart disease and is never considered normal. However, there are several normal variants that can appear on an ECG, such as sinus arrhythmia, right axis deviation (common in tall and thin individuals), left axis deviation (common in short, obese individuals), and partial right bundle branch block. Additionally, athletes may exhibit certain normal variants due to their high vagal tone, such as sinus bradycardia and 1st degree atrioventricular block.

Normal Variants in Athlete ECGs

Athletes may exhibit certain ECG changes that are considered normal variants. These include sinus bradycardia, junctional rhythm, first degree heart block, and Mobitz type 1 (Wenckebach phenomenon). Sinus bradycardia refers to a slower than normal heart rate originating from the sinus node, which is the natural pacemaker of the heart. Junctional rhythm occurs when the heart’s electrical impulses originate from the junction between the atria and ventricles, rather than the sinus node. First degree heart block is a delay in the electrical conduction between the atria and ventricles, resulting in a prolonged PR interval on the ECG. Mobitz type 1, also known as Wenckebach phenomenon, is a type of heart block where there is a progressive lengthening of the PR interval until a beat is dropped. These ECG changes are considered normal in athletes and do not necessarily indicate any underlying cardiac pathology.

The patient’s symptoms of general fatigue and polyuria suggest the possibility of type I diabetes, which can lead to diabetic ketoacidosis (DKA). DKA can occur as a complication of existing type I diabetes or as the first presentation of the disease. In rare cases, extreme stress can also cause DKA in patients with type II diabetes. DKA is caused by uncontrolled lipolysis, resulting in excess free fatty acids that are converted to ketone bodies. Common triggers include infection, missed insulin doses, and myocardial infarction.

Anxiety attacks can cause heavy breathing and abdominal pain, but they do not explain the polyuria, polydipsia, and pear-drops-smelling breath. Symptoms of anxiety attacks include chest pain, palpitations, nausea and vomiting, sweating, insomnia, flushing, tremor, and urinary frequency.

Acute pancreatitis should be ruled out in cases of central abdominal pain. Symptoms of acute pancreatitis include severe epigastric pain radiating to the back, vomiting, epigastric tenderness, ileus, and low-grade fever. Cullen’s sign and Grey-Turner’s sign are rare.

Addison’s disease, the most common cause of primary hypoadrenalism in the UK, can present similarly to this case with general fatigue and abdominal pain. Other symptoms of Addison’s disease include anorexia, nausea and vomiting, weight loss, salt-craving, hyperpigmentation, vitiligo, loss of pubic hair in women, hypotension, hypoglycaemia, hyponatraemia, and hyperkalaemia.

Hyperparathyroidism can also cause polyuria, polydipsia, and abdominal pain, but the Kussmaul respiration and pear-drops-smelling breath suggest a likely diagnosis of DKA. Symptoms of hyperparathyroidism include bone pain, osteopenia and osteoporosis, increased risk of kidney stones, constipation, nausea, vomiting and abdominal pain, and fatigue, depression, and memory impairment, all of which are symptoms of underlying hypercalcaemia.

Bromocriptine is used to treat galactorrhoea, not to induce it.

Understanding Prolactin and Galactorrhoea

Prolactin is a hormone produced by the anterior pituitary gland, and its release is regulated by various physiological factors. Dopamine is the primary inhibitor of prolactin release, and dopamine agonists like bromocriptine can be used to manage galactorrhoea. Galactorrhoea is a condition characterized by the production of breast milk in individuals who are not breastfeeding. It is important to distinguish the causes of galactorrhoea from those of gynaecomastia, which is the enlargement of male breast tissue.

Excess prolactin can lead to different symptoms in men and women. Men may experience impotence, loss of libido, and galactorrhoea, while women may have amenorrhoea and galactorrhoea. Several factors can cause raised prolactin levels, including prolactinoma, pregnancy, oestrogens, stress, exercise, sleep, acromegaly, polycystic ovarian syndrome, and primary hypothyroidism. Additionally, certain medications like metoclopramide, domperidone, phenothiazines, haloperidol, SSRIs, and opioids can also increase prolactin levels.

In summary, understanding prolactin and its effects on the body is crucial in diagnosing and managing conditions like galactorrhoea. Identifying the underlying causes of raised prolactin levels is essential in providing appropriate treatment and improving patient outcomes.

Diagnostic Methods for Renal Amyloidosis

Renal amyloidosis is a condition that can be challenging to diagnose. It is caused by the accumulation of proteinaceous material in tissues, which can be identified through a biopsy. Congo-red staining extracellular fibrillar material is a characteristic feature of amyloid protein in the kidney. While a urine dip may show proteinuria, a renal biopsy is necessary for a definitive diagnosis as proteinuria can be caused by other conditions. A bone marrow biopsy can confirm amyloidosis if there is suspicion of bone marrow infiltration. CT scans of the abdomen may reveal abnormalities in the kidneys or lymph nodes, but a renal biopsy is still required for a definitive diagnosis. As amyloidosis can affect other organs, a lung biopsy may not be the most targeted approach for diagnosing renal amyloidosis. Overall, a renal biopsy is the most reliable method for diagnosing renal amyloidosis.

Interactions with Levothyroxine: Understanding the Effects of Different Medications

Levothyroxine is a medication used to treat hypothyroidism, a condition where the thyroid gland does not produce enough thyroid hormone. However, certain medications can interact with levothyroxine and affect its absorption and effectiveness. Let’s explore the effects of different medications on levothyroxine and how they can impact thyroid function tests.

Ferrous Fumarate: Iron salts can reduce the absorption of levothyroxine, leading to inadequate replacement and hypothyroidism. It is recommended to take these medications at least four hours apart to avoid this interaction.

Amitriptyline: While thyroid hormones can enhance the effect of amitriptyline, this medication does not reduce the effect of levothyroxine and would not cause hypothyroidism.

Amlodipine: There is no interaction between amlodipine and levothyroxine, and this medication would not affect thyroid function tests.

Aspirin: Similarly, there is no interaction between aspirin and levothyroxine, and the use of this medication would not impact thyroid function tests.

Ranitidine: While antacids can reduce levothyroxine absorption, ranitidine is an H2 receptor antagonist and not classified as an antacid. Therefore, there is no interaction between ranitidine and levothyroxine.

In conclusion, it is important to be aware of potential interactions between medications and levothyroxine to ensure adequate treatment of hypothyroidism. By understanding the effects of different medications, healthcare professionals can make informed decisions and adjust medication schedules as needed.

The patient is diagnosed with pre-eclampsia. According to the National Institute for Health and Care Excellence, initial treatment for severe hypertension in pregnancy (160/110mmHg or higher) should be labetalol. Delivery should not be considered before 34 weeks, unless the hypertension remains unresponsive to treatment or there are maternal or fetal indications as specified by the consultant plan. After completing a course of corticosteroids, delivery should be offered to women with pre-eclampsia at 34 weeks. In critical care situations, intravenous magnesium sulphate may be used for women who have previously experienced eclamptic fits due to severe hypertension or pre-eclampsia, but not solely to lower blood pressure. Frusemide should not be used to treat hypertension in pregnancy as it can reduce placental perfusion and cross the placental barrier.

Hypertension during pregnancy is a common occurrence that requires careful management. In normal pregnancies, blood pressure tends to decrease in the first trimester and then gradually increase to pre-pregnancy levels by term. However, in cases of hypertension during pregnancy, the systolic blood pressure is usually above 140 mmHg or the diastolic blood pressure is above 90 mmHg. Additionally, an increase of more than 30 mmHg systolic or 15 mmHg diastolic from the initial readings may also indicate hypertension.

There are three categories of hypertension during pregnancy: pre-existing hypertension, pregnancy-induced hypertension (PIH), and pre-eclampsia. Pre-existing hypertension refers to a history of hypertension before pregnancy or elevated blood pressure before 20 weeks gestation. PIH occurs in the second half of pregnancy and resolves after birth. Pre-eclampsia is characterized by hypertension and proteinuria, and may also involve edema.

The management of hypertension during pregnancy involves the use of antihypertensive medications such as labetalol, nifedipine, and hydralazine. In cases of pre-existing hypertension, ACE inhibitors and angiotensin II receptor blockers should be stopped immediately and alternative medications should be prescribed. Women who are at high risk of developing pre-eclampsia should take aspirin from 12 weeks until the birth of the baby. It is important to carefully monitor blood pressure and proteinuria levels during pregnancy to ensure the health of both the mother and the baby.

Differential Diagnosis for a Swollen Calf: Understanding Acute Compartment Syndrome and Other Potential Causes

A swollen calf can be a concerning symptom, especially following trauma or surgery on the lower limb. One potential cause is acute compartment syndrome, which is a surgical emergency that can lead to limb-threatening complications. This condition occurs when pressure within a closed fascial compartment increases and compromises the neurovascular supply to the muscles within that compartment. Other potential causes of a swollen calf include a ruptured Baker’s cyst, acute limb ischaemia, cellulitis, and deep vein thrombosis (DVT). Understanding the clinical features and differential diagnosis of these conditions is crucial for prompt and appropriate management.

After a subarachnoid haemorrhage, the preferred treatment for most intracranial aneurysms is coiling by an interventional neuroradiologist. This is the most probable course of action given the patient’s stable condition. If the patient showed signs of raised intracranial pressure, such as haemodynamic instability or a change in GCS, craniotomy and clipping of the aneurysm might be considered. However, regardless of whether the aneurysm is coiled or clipped, the primary objective is to prevent further bleeding by mechanically occluding the aneurysm, preferably within the first 24 hours. Therefore, the other options are unlikely to be the correct and definitive management for the patient’s condition.

A subarachnoid haemorrhage (SAH) is a type of bleeding that occurs within the subarachnoid space of the meninges in the brain. It can be caused by head injury or occur spontaneously. Spontaneous SAH is often caused by an intracranial aneurysm, which accounts for around 85% of cases. Other causes include arteriovenous malformation, pituitary apoplexy, and mycotic aneurysms. The classic symptoms of SAH include a sudden and severe headache, nausea and vomiting, meningism, coma, seizures, and ECG changes.

The first-line investigation for SAH is a non-contrast CT head, which can detect acute blood in the basal cisterns, sulci, and ventricular system. If the CT is normal within 6 hours of symptom onset, a lumbar puncture is not recommended. However, if the CT is normal after 6 hours, a lumbar puncture should be performed at least 12 hours after symptom onset to check for xanthochromia and other CSF findings consistent with SAH. If SAH is confirmed, referral to neurosurgery is necessary to identify the underlying cause and provide urgent treatment.

Management of aneurysmal SAH involves supportive care, such as bed rest, analgesia, and venous thromboembolism prophylaxis. Vasospasm is prevented with oral nimodipine, and intracranial aneurysms require prompt intervention to prevent rebleeding. Most aneurysms are treated with a coil by interventional neuroradiologists, but some require a craniotomy and clipping by a neurosurgeon. Complications of aneurysmal SAH include re-bleeding, hydrocephalus, vasospasm, and hyponatraemia. Predictive factors for SAH include conscious level on admission, age, and amount of blood visible on CT head.

Differential Diagnosis for a 25-Year-Old Man with Renal Issues

Upon reviewing the history and test results of a 25-year-old man with renal issues, several potential diagnoses can be considered. Chronic reflux nephropathy appears to be the most likely diagnosis, given the patient’s history of urinary tract infections as a child, ultrasound scan results, and elevated creatinine levels. Further testing, such as renal tract computed tomography and a voiding cystourethrogram, can confirm this diagnosis.

Essential hypertension, while a risk factor for reno-vascular disease, is unlikely to be the cause of the patient’s symptoms. It would not lead to a rise in creatinine or asymmetrical kidneys in a young patient.

IgA nephropathy is another potential diagnosis, but the patient’s lack of haematuria or history of recent illness does not support this diagnosis. The history of urinary tract infections also does not align with IgA nephropathy.

Renal artery stenosis is relatively rare in young patients and would lead to a unilaterally reduced kidney size, which does not fit with the patient’s symptoms.

White coat hypertension, while a possibility, would not explain the rise in creatinine or the reduced size and scarring of the left kidney. A 24-hour blood pressure monitor may be needed to differentiate between persistent hypertension and white coat hypertension.

In conclusion, chronic reflux nephropathy is the most likely diagnosis for this patient, but further testing may be necessary to confirm the diagnosis and rule out other potential causes.

Edward’s syndrome is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. The baby affected by this syndrome will have experienced slow growth in the womb and will have a low birthweight. Unfortunately, around half of those who survive to birth will pass away within two weeks, and only one in every five will live for at least three months. The survival rate beyond one year is only one in every 12 babies born with Edwards’ syndrome. This information is according to NHS Choices.

Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions. Edward’s syndrome, also known as trisomy 18, is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. Fragile X syndrome is characterized by learning difficulties, macrocephaly, long face, large ears, and macro-orchidism. Noonan syndrome is characterized by a webbed neck, pectus excavatum, short stature, and pulmonary stenosis. Pierre-Robin syndrome is characterized by micrognathia, posterior displacement of the tongue, and cleft palate. Prader-Willi syndrome is characterized by hypotonia, hypogonadism, and obesity. William’s syndrome is characterized by short stature, learning difficulties, friendly, extrovert personality, and transient neonatal hypercalcaemia. Cri du chat syndrome, also known as chromosome 5p deletion syndrome, is characterized by a characteristic cry, feeding difficulties and poor weight gain, learning difficulties, microcephaly and micrognathism, and hypertelorism. It is important to note that Treacher-Collins syndrome is similar to Pierre-Robin syndrome, but it is autosomal dominant and usually has a family history of similar problems.

If a person has undergone a splenectomy, their HbA1c level may be falsely elevated due to the longer lifespan of their red blood cells. HbA1c testing is commonly used to determine diabetes, as it provides an average blood glucose level over a three-month period, which is the lifespan of a typical red blood cell. A higher HbA1c reading can be caused by either a higher average blood glucose concentration or a longer red cell lifespan. Therefore, only a splenectomy would result in an overestimation of blood sugar levels, as it increases the lifespan of red blood cells, while all other conditions would decrease their lifespan and lower the HbA1c reading.

Understanding Glycosylated Haemoglobin (HbA1c) in Diabetes Mellitus

Glycosylated haemoglobin (HbA1c) is a commonly used measure of long-term blood sugar control in diabetes mellitus. It is produced when glucose attaches to haemoglobin in the blood at a rate proportional to the glucose concentration. The level of HbA1c is influenced by the lifespan of red blood cells and the average blood glucose concentration. However, certain conditions such as sickle-cell anaemia, GP6D deficiency, and haemodialysis can interfere with accurate interpretation of HbA1c levels.

HbA1c is believed to reflect the blood glucose levels over the past 2-4 weeks, although it is generally thought to represent the previous 3 months. It is recommended that HbA1c be checked every 3-6 months until stable, then every 6 months. The Diabetes Control and Complications Trial (DCCT) has studied the complex relationship between HbA1c and average blood glucose. The International Federation of Clinical Chemistry (IFCC) has developed a new standardised method for reporting HbA1c in mmol per mol of haemoglobin without glucose attached.

Understanding HbA1c is crucial in managing diabetes mellitus and achieving optimal blood sugar control.

The regular surveillance evaluations that were conducted at 8 months, 2 years, and 3-4 years have been discontinued. Nevertheless, if a child is considered to be in a vulnerable situation, it is recommended to conduct more frequent assessments.

Child Health Surveillance in the UK

Child health surveillance in the UK involves a series of checks and tests to ensure the well-being of children from before birth to pre-school age. During the antenatal period, healthcare professionals ensure that the baby is growing properly and check for any maternal infections that may affect the baby. An ultrasound scan is also performed to detect any fetal abnormalities, and blood tests are done to check for neural tube defects.

After birth, a clinical examination of the newborn is conducted, and a hearing screening test is performed. The mother is given a Personal Child Health Record, which contains important information about the child’s health. Within the first month, a heel-prick test is done to check for hypothyroidism, PKU, metabolic diseases, cystic fibrosis, and medium-chain acyl Co-A dehydrogenase deficiency (MCADD). A midwife visit may also be conducted within the first four weeks.

In the following months, health visitor input is provided, and a GP examination is done at 6-8 weeks. Routine immunisations are also given during this time. Ongoing monitoring of growth, vision, and hearing is conducted, and health professionals provide advice on immunisations, diet, and accident prevention.

In pre-school, a national orthoptist-led programme for pre-school vision screening is set to be introduced. Overall, child health surveillance in the UK aims to ensure that children receive the necessary care and attention to promote their health and well-being.

Management of Lichen Planus: Topical Clobetasone Butyrate

Lichen planus is a skin condition that can be managed with daily potent topical steroids, such as clobetasone butyrate. As the lesions improve, the potency of the steroid can be decreased. It is important to advise patients to only treat the active, itchy lesions and not the post-inflammatory hyperpigmentation to minimize side effects. These treatments can also be used on the genital skin and scalp. Sedating antihistamines may help with itching at night, but should only be used periodically. Emollients and oral antihistamines are not first-line treatments for lichen planus. Referring for a punch biopsy is not necessary unless the presentation is atypical. The characteristic histological findings of lichen planus include irregular acanthosis of the epidermis, irregular thickening of the granular layer, and compact hyperkeratosis in the center of the papule. Topical clotrimazole and dapsone are not first-line treatments for lichen planus.

Strengthened Warnings on the Neuropsychiatric Side-Effects of Mefloquine

Mefloquine, also known as Lariam, is a medication used for the prevention and treatment of certain types of malaria. However, there has been a long-standing concern about its potential neuropsychiatric side-effects. A recent review has led to strengthened warnings about the risks associated with mefloquine.

Patients taking mefloquine may experience side-effects such as nightmares or anxiety, which could be a warning sign of a more serious neuropsychiatric event. There have been reports of suicide and deliberate self-harm in patients taking mefloquine. Adverse reactions may also continue for several months due to the long half-life of the medication.

It is important to note that mefloquine should not be used in patients with a history of anxiety, depression, schizophrenia, or other psychiatric disorders. If patients experience any neuropsychiatric side-effects while taking mefloquine, they should stop taking the medication and seek medical advice. These strengthened warnings aim to ensure that patients are fully informed about the potential risks associated with mefloquine.

Treatment Options for Primary Biliary Cholangitis

Primary biliary cholangitis (PBC) is an inflammatory condition that affects middle-aged, overweight women. The most common symptoms are fatigue and pruritis, along with elevated alkaline phosphatase levels. Ursodeoxycholic acid is the preferred treatment for PBC as it slows disease progression. Cholestyramine can effectively control pruritis, but it does not affect overall mortality in PBC. Liver transplantation is reserved for cases where medical alternatives have failed. Loratadine is not indicated for PBC, and prednisolone is used in the treatment of autoimmune hepatitis, which is a different condition.
