Crohn’s disease can manifest in various ways outside of the intestines, such as aphthous mouth ulcers which are linked to disease activity. However, psoriasis is an extra-intestinal manifestation of Crohn’s disease that is not related to disease activity. It is important to note that NSAIDs may heighten the likelihood of a Crohn’s disease relapse. Unlike ulcerative colitis, smoking increases the risk of Crohn’s disease. Additionally, experiencing infectious gastroenteritis can increase the risk of Crohn’s disease by four times, especially within the first year following the episode.

Crohn’s disease is a type of inflammatory bowel disease that can affect any part of the digestive tract. The National Institute for Health and Care Excellence (NICE) has published guidelines for managing this condition. Patients are advised to quit smoking, as it can worsen Crohn’s disease. While some studies suggest that NSAIDs and the combined oral contraceptive pill may increase the risk of relapse, the evidence is not conclusive.

To induce remission, glucocorticoids are typically used, but budesonide may be an alternative for some patients. Enteral feeding with an elemental diet may also be used, especially in young children or when there are concerns about steroid side effects. Second-line options include 5-ASA drugs, such as mesalazine, and add-on medications like azathioprine or mercaptopurine. Infliximab is useful for refractory disease and fistulating Crohn’s, and metronidazole is often used for isolated peri-anal disease.

Maintaining remission involves stopping smoking and using azathioprine or mercaptopurine as first-line options. Methotrexate is a second-line option. Surgery is eventually required for around 80% of patients with Crohn’s disease, depending on the location and severity of the disease. Complications of Crohn’s disease include small bowel cancer, colorectal cancer, and osteoporosis. Before offering azathioprine or mercaptopurine, it is important to assess thiopurine methyltransferase (TPMT) activity.

It is evident from the given details that Roger’s freedom is being curtailed as the nurses have locked the door to prevent him from leaving, citing concerns about his conduct. This constitutes a deprivation of liberty.

The website of the Social Care Institute for Excellence offers a comprehensive explanation of the DOLS (Deprivation of Liberty Safeguards) law. It cites instances that would qualify as a ‘deprivation of liberty,’ such as ’employing locks or keypads that restrict a person’s movement in and out of various sections of a structure.’

Understanding the Deprivation of Liberty Safeguards

The Deprivation of Liberty Safeguards (DOLS) are a set of regulations that were introduced as an amendment to the Mental Capacity Act 2005. These safeguards apply only in England and Wales and are designed to ensure that individuals are not deprived of their liberty without proper justification. While the Mental Capacity Act allows for the use of restraint and restrictions, these can only be used if they are deemed to be in the best interests of the person in question. However, if these measures are likely to result in the deprivation of an individual’s liberty, additional safeguards must be put in place.

The DOLS can only be used in care homes or hospitals, and in other settings, the Court of Protection must be consulted to determine whether an individual can be deprived of their liberty. Before a standard authorisation can be given, six assessments must be carried out to ensure that the individual’s rights are being protected. If a standard authorisation is granted, the person must have a relevant person’s representative appointed to represent them legally. This representative is usually a family member or friend.

Other safeguards include the right to challenge authorisations in the Court of Protection without cost and access to independent mental capacity advocates (IMCAs). These measures are in place to ensure that individuals are not deprived of their liberty without proper justification and that their rights are protected at all times.

ABPM vs Solitary Clinic Blood Pressure

Note the difference between a solitary clinic blood pressure and ABPM. ABPM stands for ambulatory blood pressure monitoring, which is a method of measuring blood pressure over a 24-hour period. This is different from a solitary clinic blood pressure, which is taken in a medical setting at a single point in time.

For patients over the age of 80, their daytime average ABPM or average HBPM (hospital blood pressure monitoring) blood pressure should be less than 145/85 mmHg. This is according to NICE guidelines, which state that for people under 80 years old, the daytime average ABPM or average HBPM blood pressure should be lower than 135/85 mmHg.

It’s important to note that ABPM targets are different from clinic BP targets. This is because ABPM provides a more accurate and comprehensive picture of a patient’s blood pressure over a 24-hour period, rather than just a single reading in a medical setting. By using ABPM, healthcare professionals can better monitor and manage a patient’s blood pressure, especially for those over the age of 80.

If a child between the ages of 6 and 11 is experiencing an anaphylactic reaction, they should be given a dose of 300 micrograms (0.3ml) of adrenaline. This dose can be repeated every 5 minutes if necessary. Based on the patient’s age of 8 years old, it is recommended to administer the adrenaline at a dose of 300 micrograms IM immediately, as stated in the BNF. It is likely that the child is having an anaphylactic reaction to the nuts they were exposed to in the GP waiting room.

Anaphylaxis is a severe and potentially life-threatening allergic reaction that affects the entire body. It can be caused by various triggers, including food, drugs, and insect venom. The symptoms of anaphylaxis typically develop suddenly and progress rapidly, affecting the airway, breathing, and circulation. Swelling of the throat and tongue, hoarse voice, and stridor are common airway problems, while respiratory wheeze and dyspnea are common breathing problems. Hypotension and tachycardia are common circulation problems. Skin and mucosal changes, such as generalized pruritus and widespread erythematous or urticarial rash, are also present in around 80-90% of patients.

The most important drug in the management of anaphylaxis is intramuscular adrenaline, which should be administered as soon as possible. The recommended doses of adrenaline vary depending on the patient’s age, with the highest dose being 500 micrograms for adults and children over 12 years old. Adrenaline can be repeated every 5 minutes if necessary. If the patient’s respiratory and/or cardiovascular problems persist despite two doses of IM adrenaline, IV fluids should be given for shock, and expert help should be sought for consideration of an IV adrenaline infusion.

Following stabilisation, non-sedating oral antihistamines may be given to patients with persisting skin symptoms. Patients with a new diagnosis of anaphylaxis should be referred to a specialist allergy clinic, and an adrenaline injector should be given as an interim measure before the specialist allergy assessment. Patients should be prescribed two adrenaline auto-injectors, and training should be provided on how to use them. A risk-stratified approach to discharge should be taken, as biphasic reactions can occur in up to 20% of patients. The Resus Council UK recommends a fast-track discharge for patients who have had a good response to a single dose of adrenaline and have been given an adrenaline auto-injector and trained how to use it. Patients who require two doses of IM adrenaline or have had a previous biphasic reaction should be observed for a minimum of 6 hours after symptom resolution, while those who have had a severe reaction requiring more than two doses of IM adrenaline or have severe asthma should be observed for a minimum of 12 hours after symptom resolution. Patients who present late at night or in areas where access to emergency care may be difficult should also be observed for a minimum of 12

The Link Between Diabetes and Other Medical Conditions

Diabetes, a chronic metabolic disorder, is often associated with other medical conditions. Autoimmune diseases such as Hashimoto’s thyroiditis and Graves’ disease, which affect the thyroid gland, have a higher prevalence in women with diabetes. However, diabetes doesn’t increase the risk of developing giant cell arteritis (GCA) or polymyalgia rheumatica (PMR), but the high-dose steroids used to treat these conditions can increase the risk of developing type II diabetes (T2DM). Anaphylaxis, a severe allergic reaction, is not linked to diabetes, but increased steroid use in asthmatic patients, a chronic respiratory condition, is a risk factor for developing T2DM. Systemic lupus erythematosus (SLE), an autoimmune condition that causes widespread inflammation, doesn’t have a significant increased risk in diabetic patients, but steroid treatments used to treat SLE can increase the risk of developing T2DM. Understanding the link between diabetes and other medical conditions is crucial for effective management and treatment.

A hydatidiform mole is characterized by painless vaginal bleeding. High levels of hCG may cause symptoms of thyrotoxicosis, which can mimic thyroid stimulating hormone.

Gestational trophoblastic disorders refer to a range of conditions that originate from the placental trophoblast. These disorders include complete hydatidiform mole, partial hydatidiform mole, and choriocarcinoma. Complete hydatidiform mole is a benign tumor of trophoblastic material that occurs when an empty egg is fertilized by a single sperm that duplicates its own DNA, resulting in all 46 chromosomes being of paternal origin. Symptoms of this disorder include bleeding in the first or early second trimester, exaggerated pregnancy symptoms, a large uterus for dates, and high levels of human chorionic gonadotropin (hCG) in the blood. Hypertension and hyperthyroidism may also be present. Urgent referral to a specialist center is necessary, and evacuation of the uterus is performed. Effective contraception is recommended to avoid pregnancy in the next 12 months. About 2-3% of cases may progress to choriocarcinoma. In partial mole, a normal haploid egg may be fertilized by two sperms or one sperm with duplication of paternal chromosomes, resulting in DNA that is both maternal and paternal in origin. Fetal parts may be visible, and the condition is usually triploid.

Differentiating between Ankylosing Spondylitis, Rheumatoid Arthritis, Lumbar Disc Prolapse, Spinal Stenosis, and Paget’s Disease

When examining X-rays of the spine, certain abnormalities can suggest specific conditions. For example, irregularity and loss of cortical margins, widening of the joint space, and subsequent marginal sclerosis, narrowing, and fusion of the sacroiliac joint may indicate ankylosing spondylitis. Anterior squaring of the vertebrae, or loss of normal concavity of the anterior border of a vertebral body, may also be present in ankylosing spondylitis, particularly in the lumbar spine.

Rheumatoid arthritis, on the other hand, typically affects peripheral joints such as the hips, knees, hands, and feet. It is more common in women and often presents in the fifth decade of life.

Lumbar disc prolapse and spinal stenosis can both cause a reduction in joint space. Lumbar disc prolapse may present with sciatica, while spinal stenosis may cause pseudoclaudication, or discomfort and pain in the legs on walking that is relieved by rest and bending forwards. Spinal stenosis is more common in older individuals.

Paget’s disease, which is typically diagnosed after the age of 40, may present with bone pain, deformity, deafness, and pathological fractures. While it can be associated with vertebral body squaring, it usually involves individual vertebrae. Diagnosis is established by a raised serum alkaline phosphatase level and normal liver function tests.

In summary, careful examination of X-rays can help differentiate between various spinal conditions, including ankylosing spondylitis, rheumatoid arthritis, lumbar disc prolapse, spinal stenosis, and Paget’s disease.

For women over 65 years old with suspected urinary tract infections, it is recommended to send an MSU for urine culture according to current NICE CKS guidance. Asymptomatic bacteriuria is common in older patients, so a urine dip is no longer recommended. However, a urine culture can help determine appropriate antibiotic therapy in this age group. Antibiotics should be prescribed for 3 days in women and 7 days in men with suspected urinary tract infections. Since the woman is experiencing symptoms, it is appropriate to administer antibiotics immediately rather than waiting for culture results.

Urinary tract infections (UTIs) are common in adults and can affect different parts of the urinary tract. Lower UTIs are more common and can be managed with antibiotics. For non-pregnant women, local antibiotic guidelines should be followed, and a urine culture should be sent if they are aged over 65 years or have visible or non-visible haematuria. Trimethoprim or nitrofurantoin for three days are recommended by NICE Clinical Knowledge Summaries. Pregnant women with symptoms should have a urine culture sent, and first-line treatment is nitrofurantoin, while amoxicillin or cefalexin can be used as second-line treatment. Asymptomatic bacteriuria in pregnant women should also be treated with antibiotics. Men with UTIs should be offered antibiotics for seven days, and a urine culture should be sent before starting treatment. Catheterised patients should not be treated for asymptomatic bacteriuria, but if they are symptomatic, a seven-day course of antibiotics should be given, and the catheter should be removed or changed if it has been in place for more than seven days. For patients with signs of acute pyelonephritis, hospital admission should be considered, and local antibiotic guidelines should be followed. The BNF recommends a broad-spectrum cephalosporin or a quinolone for 10-14 days for non-pregnant women.

LTOT Prolongs Survival in COPD

Adequate evidence supporting the use of long-term oxygen therapy (LTOT) to prolong survival is only available for chronic obstructive pulmonary disease (COPD). However, it is commonly assumed that this therapy can also be beneficial for other chronic hypoxaemic lung conditions.

Rhesus negative mothers can develop anti-D IgG antibodies if they deliver a Rh +ve child, which can cause haemolysis in future pregnancies. Prevention involves testing for D antibodies and giving anti-D prophylaxis at 28 and 34 weeks. Anti-D should also be given in various situations, such as delivery of a Rh +ve infant or amniocentesis. Tests include cord blood FBC, blood group, direct Coombs test, and Kleihauer test. Affected fetuses may experience oedema, jaundice, anaemia, hepatosplenomegaly, heart failure, and kernicterus, and may require transfusions and UV phototherapy.

Huntington disease is an autosomal dominant condition, which implies that the patient has one normal and one faulty copy of the gene. The faulty copy is dominant and causes the disease. If an affected patient has a child, the child has a 50% chance of inheriting the faulty gene and developing the condition, and a 50% chance of inheriting the normal gene and not developing the disease.

Autosomal Dominant Inheritance: Characteristics and Complicating Factors

Autosomal dominant diseases are genetic disorders that are inherited in an autosomal dominant pattern. This means that both homozygotes and heterozygotes manifest the disease, and there is no carrier state. Both males and females can be affected, and only affected individuals can pass on the disease. The disease is passed on to 50% of children, and it normally appears in every generation. The risk remains the same for each successive pregnancy.

However, there are complicating factors that can affect the inheritance of autosomal dominant diseases. One of these factors is non-penetrance, which refers to the lack of clinical signs and symptoms despite having an abnormal gene. For example, 40% of individuals with otosclerosis may not show any symptoms. Another complicating factor is spontaneous mutation, which occurs when there is a new mutation in one of the gametes. This means that 80% of individuals with achondroplasia have unaffected parents.

In summary, autosomal dominant inheritance is characterized by certain patterns of inheritance, but there are also complicating factors that can affect the expression of the disease. Understanding these factors is important for genetic counseling and for predicting the risk of passing on the disease to future generations.

Understanding and Treating Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by obsessive thoughts and compulsive behaviors. While many people may exhibit some obsessive or compulsive tendencies, the key to diagnosing OCD is whether it causes distress or interferes with daily functioning.

Cognitive behavioral therapy, specifically exposure and response prevention, is the first-line treatment for OCD. This type of therapy helps individuals confront their fears and learn to resist the urge to engage in compulsive behaviors. If a patient cannot participate in therapy or if it is not effective, selective serotonin reuptake inhibitors (SSRIs) may be prescribed. Clomipramine is an alternative medication to SSRIs.

It is important to note that OCD can affect anyone, regardless of gender, and typically has an onset in adolescence or early adulthood. If you or someone you know is struggling with OCD, seeking professional help can lead to effective treatment and improved quality of life.

Diagnostic Tests for Cushing Syndrome

Cushing syndrome can be caused by various factors, including pituitary adenoma, ectopic ACTH secretion, adrenal adenoma, adrenal carcinoma, adrenal nodular hyperplasia, or excess glucocorticoid administration. To diagnose Cushing syndrome, several diagnostic tests are available.

Undetectable Serum Adrenocorticotropic Hormone (ACTH) Level: In adrenal causes of Cushing syndrome, the ACTH level is suppressed or undetectable. However, a normal ACTH level can sometimes be found in pituitary-driven Cushing syndrome and ectopic ACTH, as there is overlap between the normal and elevated ranges.

Raised Urine Cortisol/Creatinine Ratio: This test is not helpful in differentiating the cause of Cushing syndrome as the urine cortisol/creatinine ratio is elevated in all causes.

0900 h Serum Cortisol of 200 nmol/l after Overnight Low Dose Dexamethasone Test: An unsuppressed 0900 h cortisol level after an overnight dexamethasone suppression test is diagnostic for Cushing syndrome. However, all causes of Cushing syndrome will give an unsuppressed 0900 h cortisol level.

Normal 0900 h Serum Cortisol Level: The serum cortisol level can be normal in both adrenal and pituitary causes, as it has a wide range of normal. However, there is a loss of diurnal variation with reduced cortisol production in the evening compared with the morning.

Serum Potassium of 2.2 mmol/l: Serum potassium is most likely to be low in cases of ectopic adrenocorticotropic hormone (ACTH) and can be due to the mineralocorticoid of cortisol itself or in adrenal carcinoma as a result of excessive mineralocorticoid (aldosterone) activity.

Diagnostic Tests for Cushing Syndrome

Proteinuria in Chronic Kidney Disease: Diagnosis and Management

Proteinuria is a significant indicator of chronic kidney disease, particularly in cases of diabetic nephropathy. The National Institute for Health and Care Excellence (NICE) recommends using the albumin:creatinine ratio (ACR) over the protein:creatinine ratio (PCR) for identifying patients with proteinuria due to its higher sensitivity. PCR can be used for quantification and monitoring of proteinuria, but ACR is preferred for diabetics. Urine reagent strips are not recommended unless they express the result as an ACR.

To collect an ACR sample, a first-pass morning urine specimen is preferred as it avoids the need to collect urine over a 24-hour period. If the initial ACR is between 3 mg/mmol and 70 mg/mmol, a subsequent early morning sample should confirm it. However, if the initial ACR is 70 mg/mmol or more, a repeat sample is unnecessary.

According to NICE guidelines, a confirmed ACR of 3 mg/mmol or more is considered clinically important proteinuria. Referral to a nephrologist is recommended for patients with a urinary ACR of 70 mg/mmol or more, unless it is known to be caused by diabetes and already appropriately treated. Referral is also necessary for patients with an ACR of 30 mg/mmol or more, along with persistent haematuria after exclusion of a urinary tract infection. For patients with an ACR between 3-29 mg/mmol and persistent haematuria, referral to a nephrologist is considered if they have other risk factors such as declining eGFR or cardiovascular disease.

The frequency of monitoring eGFR varies depending on the eGFR and ACR categories. ACE inhibitors or angiotensin II receptor blockers are key in managing proteinuria and should be used first-line in patients with coexistent hypertension and CKD if the ACR is > 30 mg/mmol. If the ACR is > 70 mg/mmol, they are indicated regardless of the patient’s blood pressure.

Management of Overactive Bladder in Frail Older Men

When dealing with an overactive bladder in frail older men, it is important to rule out other diagnoses and try bladder training before considering medication. Oxybutynin is not recommended due to potential risks, while solifenacin is unlikely to work. Duloxetine is not recommended for overactive bladder in men, but may be used for stress incontinence in women. Desmopressin has no role in overactive bladder in men. Urology referral may be an option, but mirabegron can be used prior to referral and its effectiveness can be reviewed at 4-6 weeks. It is important to note that mirabegron is a ‘black triangle’ drug and is subject to intensive post-marketing safety surveillance. For more information on managing overactive bladder in men, visit the link provided.

Degenerative Cervical Myelopathy (DCM) is a condition that affects the spinal cord in the neck region. It is caused by the compression of the spinal cord due to degenerative changes in the cervical spine. DCM is a common condition, with an estimated prevalence of 1-2% in the general population [1]. The condition is more common in older adults, with a peak incidence in the sixth decade of life [2].

The pathophysiology of DCM involves the gradual degeneration of the cervical spine, which can lead to the compression of the spinal cord. This compression can cause a range of symptoms, including neck pain, arm pain, weakness, and numbness. In severe cases, DCM can lead to paralysis and loss of bladder and bowel control [2].

Diagnosis of DCM requires the finding of MRI compression in conjunction with appropriate signs and symptoms. Asymptomatic degenerative disk disease and spondylosis of the cervical spine can be seen on MRI, but these findings alone do not indicate DCM [3].

In conclusion, DCM is a common condition that affects the spinal cord in the neck region. It is caused by the compression of the spinal cord due to degenerative changes in the cervical spine. Diagnosis of DCM requires the finding of MRI compression in conjunction with appropriate signs and symptoms.

Degenerative cervical myelopathy (DCM) is a condition that has several risk factors, including smoking, genetics, and certain occupations that expose individuals to high axial loading. The symptoms of DCM can vary in severity and may include pain, loss of motor function, loss of sensory function, and loss of autonomic function. Early symptoms may be subtle and difficult to detect, but as the condition progresses, symptoms may worsen or new symptoms may appear. An MRI of the cervical spine is the gold standard test for diagnosing cervical myelopathy. All patients with DCM should be urgently referred to specialist spinal services for assessment and treatment. Decompressive surgery is currently the only effective treatment for DCM, and early treatment offers the best chance of a full recovery. Physiotherapy should only be initiated by specialist services to prevent further spinal cord damage.

If there is a sensorineural issue, the sound in Weber’s test will be perceived on the healthy side (left), suggesting a problem on the affected side (right).

Rinne’s and Weber’s Test for Differentiating Conductive and Sensorineural Deafness

Rinne’s and Weber’s tests are used to differentiate between conductive and sensorineural deafness. Rinne’s test involves placing a tuning fork over the mastoid process until the sound is no longer heard, then repositioning it just over the external acoustic meatus. A positive test indicates that air conduction (AC) is better than bone conduction (BC), while a negative test indicates that BC is better than AC, suggesting conductive deafness.

Weber’s test involves placing a tuning fork in the middle of the forehead equidistant from the patient’s ears and asking the patient which side is loudest. In unilateral sensorineural deafness, sound is localized to the unaffected side, while in unilateral conductive deafness, sound is localized to the affected side.

The table below summarizes the interpretation of Rinne and Weber tests. A normal result indicates that AC is greater than BC bilaterally and the sound is midline. Conductive hearing loss is indicated by BC being greater than AC in the affected ear and AC being greater than BC in the unaffected ear, with the sound lateralizing to the affected ear. Sensorineural hearing loss is indicated by AC being greater than BC bilaterally, with the sound lateralizing to the unaffected ear.

Overall, Rinne’s and Weber’s tests are useful tools for differentiating between conductive and sensorineural deafness, allowing for appropriate management and treatment.

Hypertrophic obstructive cardiomyopathy (HCM) is a condition where the left ventricle of the heart becomes enlarged, often affecting the interventricular septum and causing a blockage in the left ventricular outflow tract. Patients with HCM typically experience shortness of breath, but may also have angina or fainting spells. Physical examination may reveal a prominent presystolic S4 gallop, a harsh systolic ejection murmur, and a left ventricular apical impulse. The Valsalva manoeuvre and standing up from a squatting position can increase the intensity of the murmur. An echocardiogram is the preferred diagnostic test for HCM. Syncope occurs in 15-25% of HCM patients, and recurrent syncope in young patients may indicate an increased risk of sudden death. Aortic stenosis, on the other hand, typically affects older patients and causes exertional syncope. The ejection systolic murmur associated with aortic stenosis is loudest at the upper right sternal border and radiates to the carotids. It increases with squatting and decreases with standing and isometric muscular contraction. Atrial fibrillation can also cause syncope, but if it is associated with HCM, the underlying cause is still HCM. Vasovagal syncope is usually triggered by prolonged standing or exposure to hot, crowded environments. The term syncope excludes other conditions that cause altered consciousness, such as seizures or shock.

The patient’s symptoms of depression, nausea, constipation, and bone pain suggest a diagnosis of primary hyperparathyroidism. This condition is characterized by hypercalcaemia, which can cause the ‘moans, groans, and bones’ of hyperparathyroidism. Other common symptoms include polydipsia, polyuria, hypertension, renal stones, and pancreatitis.

It is important to distinguish primary hyperparathyroidism from secondary hyperparathyroidism, which is usually caused by renal disease. In this case, the patient’s recent blood tests showed normal renal function, making secondary hyperparathyroidism less likely. Primary hypoparathyroidism, a congenital condition, is also unlikely as it would cause low calcium and high phosphate levels, resulting in different symptoms than those presented by the patient.

Secondary hypoparathyroidism, which can result in depression due to chronic hypocalcaemia, is also unlikely as it is usually caused by damage to the parathyroid glands from neck surgery or radiation therapy, which the patient has not undergone.

Therefore, primary hyperparathyroidism remains the most likely diagnosis for this patient’s symptoms.

Primary Hyperparathyroidism: Causes, Symptoms, and Treatment

Primary hyperparathyroidism is a condition that is commonly seen in elderly females and is characterized by an unquenchable thirst and an inappropriately normal or raised parathyroid hormone level. It is usually caused by a solitary adenoma, hyperplasia, multiple adenoma, or carcinoma. While around 80% of patients are asymptomatic, the symptomatic features of primary hyperparathyroidism may include polydipsia, polyuria, depression, anorexia, nausea, constipation, peptic ulceration, pancreatitis, bone pain/fracture, renal stones, and hypertension.

Primary hyperparathyroidism is associated with hypertension and multiple endocrine neoplasia, such as MEN I and II. To diagnose this condition, doctors may perform a technetium-MIBI subtraction scan or look for a characteristic X-ray finding of hyperparathyroidism called the pepperpot skull.

The definitive management for primary hyperparathyroidism is total parathyroidectomy. However, conservative management may be offered if the calcium level is less than 0.25 mmol/L above the upper limit of normal, the patient is over 50 years old, and there is no evidence of end-organ damage. Patients who are not suitable for surgery may be treated with cinacalcet, a calcimimetic that mimics the action of calcium on tissues by allosteric activation of the calcium-sensing receptor.

In summary, primary hyperparathyroidism is a condition that can cause various symptoms and is commonly seen in elderly females. It can be diagnosed through various tests and managed through surgery or medication.

Antihistamines: Uses and Limitations in Various Skin Conditions

Urticaria, Chickenpox, atopic eczema, local reactions to insect stings, and general pruritus are common skin conditions that may benefit from antihistamines. However, the effectiveness of antihistamines varies depending on the underlying cause and the individual’s response.

For a 15-year-old girl with acute urticaria, non-sedating H1 antihistamines are the first-line treatment. If the first antihistamine is not effective, a second one may be tried.

A 4-year-old girl with Chickenpox may benefit from emollients and sedating antihistamines to relieve pruritus. Calamine lotion may also be used, but its effectiveness decreases as it dries.

Antihistamines are not routinely recommended for atopic eczema, but a non-sedating antihistamine may be tried for a month in severe cases or when there is severe itching or urticaria. Sedating antihistamines may be used for sleep disturbance.

For a 50-year-old woman with a local reaction to a wasp sting, antihistamines are most effective when used immediately after the sting. After 48 hours, they are unlikely to have a significant impact on the local reaction.

Finally, for a 65-year-old man with general pruritus but no rash, antihistamines may be prescribed, but their effectiveness is limited as histamine may not be the main cause of the pruritus.

If alginates/thickened feeds fail to alleviate symptoms in infants with GORD and they exhibit feeding difficulties, distressed behavior, or faltering growth, a trial of PPI is recommended by NICE. However, metoclopramide should not be used without specialist advice due to the risk of side-effects like dystonia. Restarting breastfeeding is not practical once it has stopped, and there is no evidence to suggest that it would improve symptoms. While cow’s milk protein intolerance should be considered as a differential diagnosis, there is currently no indication of this diagnosis. Additionally, it is not advisable to stop milk feeds for such a young baby.

Gastro-oesophageal reflux is a common cause of vomiting in infants, with around 40% of babies experiencing some degree of regurgitation. However, certain risk factors such as preterm delivery and neurological disorders can increase the likelihood of developing this condition. Symptoms typically appear before 8 weeks of age and include vomiting or regurgitation, milky vomits after feeds, and excessive crying during feeding. Diagnosis is usually made based on clinical observation.

Management of gastro-oesophageal reflux in infants involves advising parents on proper feeding positions, ensuring the infant is not overfed, and considering a trial of thickened formula or alginate therapy. However, proton pump inhibitors (PPIs) are not recommended as a first-line treatment for isolated symptoms of regurgitation. PPIs may be considered if the infant experiences unexplained feeding difficulties, distressed behavior, or faltering growth. Metoclopramide, a prokinetic agent, should only be used with specialist advice.

Complications of gastro-oesophageal reflux can include distress, failure to thrive, aspiration, frequent otitis media, and dental erosion in older children. If medical treatment is ineffective and severe complications arise, fundoplication may be considered. It is important for healthcare professionals to be aware of the risk factors, symptoms, and management options for gastro-oesophageal reflux in infants.

Childhood Diarrhoea: Causes and Treatment

Childhood diarrhoea is commonly caused by viruses, with rotavirus being the most prevalent. Other viruses such as norovirus, echoviruses, and enteroviruses can also cause diarrhoea. Rotavirus causes outbreaks of diarrhoea and vomiting during the winter and spring, affecting mainly children under 1 year old. Adults usually have some immunity to the virus, but the elderly can be susceptible. Rotavirus vaccine is now included in childhood vaccination programmes. Ciprofloxacin is not recommended for children and is ineffective against viruses. Loperamide can reduce the duration of diarrhoea, but its adverse effects are unclear and it should not be prescribed. According to NICE guidance, children should avoid school or nursery for at least 48 hours after their symptoms have settled and avoid public swimming pools for 2 weeks. Childhood diarrhoea can be effectively managed with appropriate treatment and prevention measures.

Malaria: Diagnosis and Management

Malaria is a febrile illness caused by Plasmodium species, which can lead to periodic febrile paroxysms every 48 or 72 hours, with asymptomatic intervals and a tendency to relapse. The symptoms and signs of malaria are nonspecific, making it difficult to diagnose. Therefore, it is important to exclude malaria by conducting repeated thick and thin blood smears in patients with acute fever and a history of exposure. If the patient is severely ill or symptoms persist, a therapeutic trial of antimalarial chemotherapy should not be delayed. This article discusses the diagnosis and management of malaria.

The use of trimethoprim during breastfeeding is deemed safe.

Breastfeeding Contraindications: Drugs and Other Factors to Consider

Breastfeeding is generally recommended for infants as it provides numerous benefits for both the baby and the mother. However, there are certain situations where breastfeeding may not be advisable. One of the major contraindications is the use of certain drugs by the mother, which can be harmful to the baby. Antibiotics like penicillins and cephalosporins, as well as endocrine medications like levothyroxine, can be given to breastfeeding mothers. On the other hand, drugs like ciprofloxacin, tetracycline, and benzodiazepines should be avoided.

Aside from drugs, other factors like galactosaemia and viral infections can also make breastfeeding inadvisable. In the case of HIV, some doctors believe that the benefits of breastfeeding outweigh the risk of transmission, especially in areas where infant mortality and morbidity rates are high.

It is important for healthcare professionals to be aware of these contraindications and to provide appropriate guidance to mothers who are considering breastfeeding. By doing so, they can help ensure the health and well-being of both the mother and the baby.

Calculating the Correct Dose of Trimethoprim for a Child

When administering medication to a child, it is important to calculate the correct dose based on their weight. In this case, the child weighs 20 kg and requires a dose of 4 mg/kg of trimethoprim twice daily. This equates to a total daily dose of 80 mg.

The trimethoprim solution available is 50 mg/5 ml, which can be simplified to 10 mg in 1 ml. To calculate the correct dose, we need to determine how many milliliters of the solution contain 80 mg of trimethoprim.

By dividing 80 mg by 10 mg/ml, we get a total of 8 ml. Therefore, the child should take 8 ml of the trimethoprim solution twice daily to receive the correct dose. It is important to always double-check calculations and measurements to ensure the safety and effectiveness of medication administration.

Lower Eyelid Ectropion and Eye Discomfort

Lower eyelid ectropion can lead to a gritty sensation in the eye, which can cause discomfort for the patient. This occurs due to prolonged exposure of the eye. If the patient experiences discomfort, it is recommended to refer them to an ophthalmologist for correction of the ectropion. However, this referral can be made routinely and is not considered urgent. In the meantime, ocular lubricants can be given to relieve the symptoms.

Cluster headaches are often triggered by alcohol, and they typically affect individuals of a certain age and gender.

Cluster headaches are a type of headache that is known to be extremely painful. They are called cluster headaches because they tend to occur in clusters that last for several weeks, usually once a year. These headaches are more common in men and smokers, and alcohol and sleep patterns may trigger an attack. The pain is typically sharp and stabbing, and it occurs around one eye. Patients may experience redness, lacrimation, lid swelling, nasal stuffiness, and miosis and ptosis in some cases.

To manage cluster headaches, acute treatment options include 100% oxygen or subcutaneous triptan. Prophylaxis involves using verapamil as the drug of choice, and a tapering dose of prednisolone may also be effective. It is recommended to seek specialist advice from a neurologist if a patient develops cluster headaches with respect to neuroimaging. Some neurologists use the term trigeminal autonomic cephalgia to group a number of conditions including cluster headache, paroxysmal hemicrania, and short-lived unilateral neuralgiform headache with conjunctival injection and tearing (SUNCT). Patients with these conditions should be referred for specialist assessment as specific treatment may be required, such as indomethacin for paroxysmal hemicrania.

Urgent Admission for a Patient with Acute Glomerulonephritis

Explanation:

A patient presenting with nephritic syndrome, including haematuria, oliguria, hypertension, and oedema, is likely suffering from acute glomerulonephritis, possibly post-streptococcal. This condition can lead to acute kidney injury and requires urgent investigation. Therefore, routine referral to paediatric nephrologists or urologists is not appropriate in this case. Instead, the patient needs to be admitted to the hospital for urgent investigation and management. While follow-up with paediatric nephrologists may be necessary, the acute presentation with hypertension and oedema requires immediate attention. A two-week rule referral for suspected malignancy is not indicated in this case.

Understanding Primary Biliary Cholangitis: Diagnostic Tests and Markers

Primary biliary cholangitis is an autoimmune disease that affects the biliary system, causing intrahepatic cholestasis and leading to cell damage, fibrosis, and cirrhosis. While there is no single definitive test for this condition, several markers can help diagnose and monitor it.

Antimitochondrial antibodies are present in 90-95% of individuals with primary biliary cholangitis, but are only found in 0.5% of normal controls. Anti-smooth muscle antibodies are also nonspecific, as they can be positive in connective tissue disease and chronic infections. Similarly, around 35% of patients with primary biliary cholangitis have positive antinuclear antibodies, but this is not specific to the condition.

Elevated levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) are common in primary biliary cholangitis, but significant elevations of alkaline phosphatase (ALP) and γ-glutamyl transpeptidase (GGT) are usually more prominent. Additionally, a polyclonal increase in IgM (sometimes associated with elevated IgG) is typical but not specific to this condition.

Overall, a combination of these diagnostic tests and markers can help identify and monitor primary biliary cholangitis.

Diagnosis and Management of PID Following IUCD Insertion

The most probable diagnosis in cases of pelvic inflammatory disease (PID) is following the insertion of an intrauterine contraceptive device (IUCD). To support the diagnosis, swabs should be taken, although negative results do not necessarily rule out PID if there are clinical indications.

Expert opinions differ on whether to remove the IUCD at the time of presentation. However, if symptoms persist after 72 hours, the IUCD should be removed. Proper diagnosis and management of PID following IUCD insertion are crucial to prevent complications and ensure the patient’s well-being.
