Hand, foot, and mouth disease is a viral infection that typically impacts children who are under the age of 10. The symptoms include fever, loss of appetite, coughing, stomach pain, and a sore throat. Following these symptoms, mouth ulcers often develop, along with a rash that typically affects the hands and feet, but can also appear on the face, buttocks, legs, and genitals. This condition is generally harmless and resolves on its own, with treatment consisting of basic pain relief.

Hand, Foot and Mouth Disease: A Contagious Condition in Children

Hand, foot and mouth disease is a viral infection that commonly affects children. It is caused by intestinal viruses from the Picornaviridae family, particularly coxsackie A16 and enterovirus 71. This condition is highly contagious and often occurs in outbreaks in nurseries.

The clinical features of hand, foot and mouth disease include mild systemic upset such as sore throat and fever, followed by the appearance of oral ulcers and vesicles on the palms and soles of the feet.

Symptomatic treatment is the only management option available, which includes general advice on hydration and analgesia. It is important to note that there is no link between this disease and cattle, and children do not need to be excluded from school. However, the Health Protection Agency recommends that children who are unwell should stay home until they feel better. If there is a large outbreak, it is advisable to contact the agency for assistance.

Toxic multinodular goitre is a condition that commonly affects women over 55 years of age and is more prevalent than Graves’ disease in the elderly. It is characterized by a goitre that obstructs and extends retrosternally, which may cause atrial fibrillation. The preferred treatment is surgery, but the patient should first be made euthyroid with carbimazole. Graves’ disease, on the other hand, is an autoimmune disorder that accounts for 75% of thyrotoxicosis cases. It is characterized by hyperthyroidism, diffuse goitre, and eye changes. Hashimoto’s thyroiditis is another autoimmune thyroiditis that initially causes hyperthyroidism followed by hypothyroidism. It is characterized by the aggressive destruction of thyroid cells, resulting in a goitre and high levels of autoantibodies against thyroid peroxidase. Thyroglossal cyst is a cyst that forms from a persistent thyroglossal duct and presents as an asymptomatic midline neck mass. Thyroid carcinoma, on the other hand, presents as a non-tender thyroid nodule with normal thyroid function tests.

Parents are informed and the NHS website states that the daughter can still receive the vaccine even if the parents object.

The human papillomavirus (HPV) is a known carcinogen that infects the skin and mucous membranes. There are numerous strains of HPV, with strains 6 and 11 causing genital warts and strains 16 and 18 linked to various cancers, particularly cervical cancer. HPV infection is responsible for over 99.7% of cervical cancers, and testing for HPV is now a crucial part of cervical cancer screening. Other cancers linked to HPV include anal, vulval, vaginal, mouth, and throat cancers. While there are other risk factors for developing cervical cancer, such as smoking and contraceptive pill use, HPV vaccination is an effective preventative measure.

The UK introduced an HPV vaccine in 2008, initially using Cervarix, which protected against HPV 16 and 18 but not 6 and 11. This decision was criticized due to the significant disease burden caused by genital warts. In 2012, Gardasil replaced Cervarix as the vaccine used, protecting against HPV 6, 11, 16, and 18. Initially given only to girls, boys were also offered the vaccine from September 2019. The vaccine is offered to all 12- and 13-year-olds in school Year 8, with the option for girls to receive a second dose between 6-24 months after the first. Men who have sex with men under the age of 45 are also recommended to receive the vaccine to protect against anal, throat, and penile cancers.

Injection site reactions are common with HPV vaccines. It should be noted that parents may not be able to prevent their daughter from receiving the vaccine, as information given to parents and available on the NHS website makes it clear that the vaccine may be administered against parental wishes.

Managing Adolescent Masturbation in Children with Learning Disabilities

It is not uncommon for adolescents with learning disabilities to engage in sexual behaviour, including masturbation. However, it is important to assess whether this behaviour is age-appropriate and not a cause for concern. In this case, as the child is masturbating privately and there are no reports of concerning behaviour from school or other services, reassurance to the patient and father that this is normal adolescent behaviour is appropriate. Referral to CAMHS, learning disability team, psychosexual counselling, or social services is not indicated at this time. It is important to use tools such as the Brook Traffic Light tool to identify normal age-appropriate sexualised behaviours and those which are a cause for concern.

Urethral Stricture: Causes, Complications, and Treatments

Urethral strictures are commonly caused by injury, urethral instrumentation, and infections such as gonorrhoea or chlamydia. In this case, the repeated cystoscopies are a likely cause. This condition can lead to complications such as urinary retention and urinary infection.

To treat urethral strictures, periodic dilation, internal urethrotomy, and external urethroplasty are common options. It is important to note that a normal feeling prostate, a normal prostate-specific antigen level, and regular bladder tumour surveillance make other diagnoses less likely in this case.

In summary, understanding the causes, complications, and treatments of urethral strictures is crucial for proper management of this condition.

Levodopa: The Most Effective Drug for Parkinson’s Disease

Levodopa is the most effective drug for treating Parkinson’s disease (PD). It replenishes depleted striatal dopamine, the lack of which causes PD symptoms. Levodopa is given with a dopa-decarboxylase inhibitor to limit side-effects such as nausea, vomiting, and cardiovascular effects. Benserazide and carbidopa are the dopa-decarboxylase inhibitors used with levodopa.

Levodopa therapy should start at a low dose and increase gradually. The final dose should be the lowest possible that controls symptoms. Intervals between doses should suit the patient’s needs. Nausea and vomiting with co-beneldopa or co-careldopa are rarely dose-limiting and can be controlled with domperidone.

Levodopa treatment can cause motor complications such as response fluctuations and dyskinesias. Response fluctuations involve large variations in motor performance, with normal function during an ‘on’ period, and restricted mobility during an ‘off’ period. End-of-dose deterioration with progressively shorter duration of benefit also occurs. Freezing of gait and falls may be problematic. Modified-release preparations may help with end-of-dose deterioration or immobility or rigidity at night.

Due to the chemotherapy-induced immunocompromisation, this patient is susceptible to a severe varicella infection and should receive varicella zoster immunoglobulin.

Chickenpox is a viral infection caused by the varicella zoster virus. It is highly contagious and can be spread through respiratory droplets. The virus can also reactivate later in life and cause shingles. Chickenpox is most infectious from four days before the rash appears until five days after. The incubation period is typically 10-21 days. Symptoms include fever and an itchy rash that starts on the head and trunk before spreading. The rash goes through stages of macular, papular, and vesicular. Management is supportive, with measures such as keeping cool and using calamine lotion. Immunocompromised patients and newborns with peripartum exposure should receive varicella zoster immunoglobulin. Complications can include secondary bacterial infection of the lesions, pneumonia, encephalitis, and rare complications such as disseminated haemorrhagic Chickenpox.

One common complication of Chickenpox is secondary bacterial infection of the lesions, which can be increased by the use of NSAIDs. This can manifest as a single infected lesion or small area of cellulitis. In rare cases, invasive group A streptococcal soft tissue infections may occur, resulting in necrotizing fasciitis. Other rare complications of Chickenpox include pneumonia, encephalitis (which may involve the cerebellum), disseminated haemorrhagic Chickenpox, and very rarely, arthritis, nephritis, and pancreatitis. It is important to note that school exclusion may be necessary, as Chickenpox is highly infectious and can be caught from someone with shingles. It is advised to avoid contact with others until all lesions have crusted over.

Retrobulbar Neuritis: A Classic Triad of Symptoms

Pain on movement of the eye, loss of colour vision, and absence of fundal signs are the three classic symptoms of retrobulbar neuritis. This condition occurs when the lesion is several millimetres behind the disc, as opposed to optic neuritis where the lesion is in the nerve head and causes disc swelling. In cases of retrobulbar neuritis, both the doctor and the patient are unable to see anything.

To summarize, retrobulbar neuritis is characterized by a specific set of symptoms that distinguish it from other types of neuritis. It is important to recognize these symptoms in order to properly diagnose and treat the condition.

Trochanteric bursitis is characterized by pain in the lateral hip/thigh area, accompanied by tenderness specifically over the greater trochanter. This condition, also known as greater trochanteric pain syndrome, typically presents as a localized issue and doesn’t affect the patient’s overall health.

Iliotibial band syndrome, on the other hand, primarily affects the knee and is unlikely to cause nighttime symptoms. Additionally, it is not common in patients of this age group.

Meralgia paresthetica is caused by compression of the lateral femoral cutaneous nerve and typically results in numbness or tingling sensations, rather than pain.

Osteoarthritis is not typically associated with pain upon direct pressure over the greater trochanter.

Understanding Greater Trochanteric Pain Syndrome

Greater trochanteric pain syndrome, also known as trochanteric bursitis, is a condition that results from the repetitive movement of the fibroelastic iliotibial band. This condition is more prevalent in women aged between 50 and 70 years. The primary symptom of this condition is pain on the lateral side of the hip and thigh. Additionally, tenderness can be felt when the greater trochanter is palpated.

Raynaud’s phenomenon is a condition where the arteries in the fingers and toes constrict excessively in response to cold or emotional stress. It can be classified as primary (Raynaud’s disease) or secondary (Raynaud’s phenomenon) depending on the underlying cause. Raynaud’s disease is more common in young women and typically affects both sides of the body. Secondary Raynaud’s phenomenon is often associated with connective tissue disorders such as scleroderma, rheumatoid arthritis, or systemic lupus erythematosus. Other causes include leukaemia, cryoglobulinaemia, use of vibrating tools, and certain medications.

If there is suspicion of secondary Raynaud’s phenomenon, patients should be referred to a specialist for further evaluation. Treatment options include calcium channel blockers such as nifedipine as a first-line therapy. In severe cases, intravenous prostacyclin (epoprostenol) infusions may be used, which can provide relief for several weeks or months. It is important to identify and treat any underlying conditions that may be contributing to the development of Raynaud’s phenomenon. Factors that suggest an underlying connective tissue disease include onset after 40 years, unilateral symptoms, rashes, presence of autoantibodies, and digital ulcers or calcinosis. In rare cases, chilblains may also be present.

Folate Content in Common Foods

Folate, also known as vitamin B9, is an essential nutrient that is important for cell growth and development. While it is found naturally in many foods, it is also added to processed foods and supplements in the form of folic acid. Here is a breakdown of the folate content in some common foods:

Spinach: With 194 μg of folic acid per 100g, spinach is the richest source of folate on this list.

Egg: While eggs contain 47 μg of folic acid per 100g, they only provide around a quarter of the folate per 100g that is found in spinach.

Carrot: Carrots contain about 21 μg of folic acid per 100g, less than half the amount of folate found in eggs and only around 11% of the amount provided by spinach.

Milk: Cow’s milk contains 5-7 μg of folic acid per 100g, making it the second-lowest source of folate in this range of options.

Apple: Apples provide the lowest source of folate in this range of options, with only about 3 μg of folic acid per 100g.

It is important to note that women who are pregnant or breastfeeding require more folate and should take a daily supplement of 400 micrograms. While many food manufacturers fortify their products with folic acid, wholegrain products already contain natural folate. Folate deficiency can occur due to poor intake, excessive alcohol consumption, or malnutrition.

The individual is exhibiting a typical symptom known as the painful arc, which is indicative of shoulder impingement. This condition is often caused by supraspinatus tendonitis.

Understanding the Rotator Cuff Muscles

The rotator cuff muscles are a group of four muscles that are responsible for the movement and stability of the shoulder joint. These muscles are known as the SItS muscles, which stands for Supraspinatus, Infraspinatus, teres minor, and Subscapularis. Each of these muscles has a specific function in the movement of the shoulder joint.

The Supraspinatus muscle is responsible for abducting the arm before the deltoid muscle. It is the most commonly injured muscle in the rotator cuff. The Infraspinatus muscle rotates the arm laterally, while the teres minor muscle adducts and rotates the arm laterally. Lastly, the Subscapularis muscle adducts and rotates the arm medially.

Understanding the functions of each of these muscles is important in diagnosing and treating rotator cuff injuries. By identifying which muscle is injured, healthcare professionals can develop a treatment plan that targets the specific muscle and promotes healing. Overall, the rotator cuff muscles play a crucial role in the movement and stability of the shoulder joint.

Intra-Articular Corticosteroid Injections for Osteoarthritis Pain

Intra-articular corticosteroid injections can be a helpful addition to treating moderate to severe osteoarthritis pain. If traditional treatments have failed, a corticosteroid injection may be an appropriate option for patients who are not interested in surgical intervention. While the injection provides short-term pain relief, it may also allow patients to engage in other interventions such as physiotherapy, which can provide longer-lasting benefits in terms of both pain and function. However, repeated injections over longer periods may cause joint damage and are generally not recommended.

Other treatment options such as capsaicin, electro-acupuncture, amitriptyline, and glucosamine are not recommended for osteoarthritis pain. Capsaicin is not recommended for shoulder problems, electro-acupuncture is not recommended for any form of osteoarthritis, and amitriptyline is not a licensed or recommended treatment for osteoarthritis. Glucosamine has insufficient data of significant efficacy to justify its cost, but patients can try over-the-counter glucosamine sulfate at a dose of 1500 mg daily and monitor their symptoms before and after three months.

Tips for Travelling with Insulin

Many patients with diabetes experience hypoglycaemia when travelling to different time zones. To avoid this, it is recommended to reduce the total daily insulin dose by 2-4% per hour of time difference. For example, a trip to Australia may require a reduction of around 30% during the flight and the first few days of adjusting to the time difference.

When travelling with insulin, it is important to carry a membership card from the local diabetes society and a letter from the doctor to make it easier to travel with needles and syringes. Insulin should not be stored in the hold as it may freeze and form crystals. If it must be stored in the hold, it should be placed in an airtight container and packed in the middle of the suitcase. After landing, it should be checked for crystals and thrown away if any are seen.

Airline rules allow staff to store excessive needles and insulin supplies for the duration of the journey. By following these tips, patients with diabetes can travel safely and comfortably with their insulin.

Initiation of Combined Hormonal Contraception Postpartum

Combined hormonal contraception can be safely started by eligible women 21 days after giving birth, provided they have no other risk factors for venous thromboembolism and are not breastfeeding. However, women who breastfeed and want to use combined hormonal contraception should wait until six weeks postpartum, regardless of whether they have additional risk factors for VTE. Studies have shown conflicting effects of combined oral contraception on breastfeeding, with some indicating less weight gain in infants of users compared to non-users when started at or before six weeks postpartum. No study has demonstrated an effect on infant weight gain when initiated after six weeks postpartum. It is important for healthcare providers to consider individual patient factors and preferences when discussing contraceptive options postpartum.

Understanding Tinea: Types, Causes, Diagnosis, and Management

Tinea is a term used to describe dermatophyte fungal infections that affect different parts of the body. There are three main types of tinea infections, namely tinea capitis, tinea corporis, and tinea pedis. Tinea capitis affects the scalp and is a common cause of scarring alopecia in children. If left untreated, it can lead to the formation of a raised, pustular, spongy/boggy mass called a kerion. The most common cause of tinea capitis in the UK and the USA is Trichophyton tonsurans, while Microsporum canis acquired from cats or dogs can also cause it. Diagnosis of tinea capitis is done through scalp scrapings, although lesions due to Microsporum canis can be detected through green fluorescence under Wood’s lamp. Management of tinea capitis involves oral antifungals such as terbinafine for Trichophyton tonsurans infections and griseofulvin for Microsporum infections. Topical ketoconazole shampoo is also given for the first two weeks to reduce transmission.

Tinea corporis, on the other hand, affects the trunk, legs, or arms and is caused by Trichophyton rubrum and Trichophyton verrucosum, which can be acquired from contact with cattle. It is characterized by well-defined annular, erythematous lesions with pustules and papules. Oral fluconazole can be used to treat tinea corporis.

Lastly, tinea pedis, also known as athlete’s foot, is characterized by itchy, peeling skin between the toes and is common in adolescence. Lesions due to Trichophyton species do not readily fluoresce under Wood’s lamp.

In summary, understanding the types, causes, diagnosis, and management of tinea infections is crucial in preventing their spread and ensuring effective treatment.

Possible Causes of Collapse: A Differential Diagnosis

When a patient presents with a history of collapse, it is important to consider various possible causes. One potential cause is vasovagal syncope, which is characterized by a prodrome of nausea and light-headedness, often associated with postural change, and a rapid recovery. Jerking movements may occur but do not necessarily indicate epilepsy. Another possibility is cardiac arrhythmia, which may be associated with chest pain or palpitations and can occur during exercise or while lying down. Epileptic seizures are less likely to be triggered by postural change and may involve tongue biting or incontinence. Hypoglycaemia typically presents with trembling, sweating, palpitations, and paraesthesiae before progressing to confusion and coma. Finally, psychogenic non-epileptic seizures may have a gradual onset, fluctuating course, and violent thrashing movements with side-to-side head movement. It is important to consider these and other potential causes when evaluating a patient with a history of collapse.

Skin Tumours: Types, Symptoms, and Management

Skin tumours are abnormal growths of skin cells that can be benign or malignant. Basal cell carcinomas are the most common malignant skin tumour, usually caused by excessive sun exposure in early life and previous sunburn. They often present as a slow-growing nodule or papule that forms an ulcer with a raised ‘rolled’ edge. Basal cell carcinomas grow slowly and rarely metastasise.

Low-risk basal cell carcinomas can be managed in primary care if the GP meets the requirements to perform skin surgery. A specialist referral is appropriate for most people with a suspicious skin lesion, and urgent referral is necessary if there is a concern that a delay may have a significant impact.

Squamous cell carcinomas have a crusted or ulcerated surface, while seborrhoeic warts have a warty pigmented surface appearance. Lentigo maligna is a melanoma in situ that progresses slowly and can remain non-invasive for years. In amelanotic melanoma, the colour may be pink, red, purple, or the colour of normal skin, and growth is likely to be rapid with a poor prognosis.

In conclusion, early detection and management of skin tumours are crucial for better outcomes. Regular skin checks and seeking medical advice for any suspicious skin lesion are recommended.

Understanding Salmon Patches in Newborns

Salmon patches, also known as stork marks or stork bites, are a type of birthmark that can be found in approximately 50% of newborn babies. These marks are characterized by their pink and blotchy appearance and are commonly found on the forehead, eyelids, and nape of the neck. While they may cause concern for new parents, salmon patches typically fade over the course of a few months. However, marks on the neck may persist. These birthmarks are caused by an overgrowth of blood vessels and are completely harmless. It is important for parents to understand that salmon patches are a common occurrence in newborns and do not require any medical treatment.

Thyroid eye disease is a condition that affects a significant proportion of patients with Graves’ disease. It is believed to be caused by an autoimmune response against an autoantigen, possibly the TSH receptor, which leads to inflammation behind the eyes. This inflammation causes the deposition of glycosaminoglycan and collagen in the muscles, resulting in symptoms such as exophthalmos, conjunctival oedema, optic disc swelling, and ophthalmoplegia. In severe cases, patients may be unable to close their eyelids, leading to sore, dry eyes and a risk of exposure keratopathy.

Prevention of thyroid eye disease is important, and smoking is the most significant modifiable risk factor. Radioiodine treatment may also increase the risk of developing or worsening eye disease, but prednisolone may help reduce this risk. Management of established thyroid eye disease may involve topical lubricants to prevent corneal inflammation, steroids, radiotherapy, or surgery.

Patients with established thyroid eye disease should be monitored closely for any signs of deterioration, such as unexplained changes in vision, corneal opacity, or disc swelling. Urgent review by an ophthalmologist is necessary in these cases to prevent further complications. Overall, thyroid eye disease is a complex condition that requires careful management and monitoring to ensure the best possible outcomes for patients.

The correct term for the probability of detecting a statistically significant difference is power. It is the probability of correctly rejecting the null hypothesis when it is false and can be calculated as ‘1 – probability of a type II error’. The null hypothesis value is not a specific value used in statistics, but rather a statement that two treatments are equally effective. P-value is not the correct answer as it refers to the probability of obtaining a result by chance. Type I error value is the probability of rejecting the null hypothesis when it is actually true, while a type II error is accepting the null hypothesis when it is false.

Significance tests are used to determine the likelihood of a null hypothesis being true. The null hypothesis states that two treatments are equally effective, while the alternative hypothesis suggests that there is a difference between the two treatments. The p value is the probability of obtaining a result by chance that is at least as extreme as the observed result, assuming the null hypothesis is true. Two types of errors can occur during significance testing: type I, where the null hypothesis is rejected when it is true, and type II, where the null hypothesis is accepted when it is false. The power of a study is the probability of correctly rejecting the null hypothesis when it is false, and it can be increased by increasing the sample size.

Factors that Increase the Risk of Problematic Behaviour

Dementia, learning disabilities, failure to impose social restriction, older age, and unchanging personal environment are all factors that can increase the risk of problematic behaviour. According to National Institute for Health and Care Excellence (NICE) guidance, dementia can lead to the development of problematic behaviour due to its progressive nature. Learning disabilities can also contribute to behavioural problems, with severity being a key factor. Failure to impose social restriction can increase the risk of problematic behaviour, while appropriate socialisation can be protective. Older age is another risk factor, with the highest risk age being during a person’s teens or twenties. Finally, an unchanging personal environment can be protective, while a change in environment is a common cause for developing problematic behaviour.

Importance of Considering Equality and Diversity in Policy Changes

By law, it is mandatory to consider equality and diversity issues before implementing any changes in practice policy. For instance, if consulting time is removed from Thursday afternoons and reallocated to Fridays, it could significantly disadvantage Muslim patients who observe Friday as a holy day. Therefore, the NHS guide to equality and diversity recommends conducting a formal impact assessment of the change to ensure that it doesn’t discriminate against any group.

While the fifth option may seem like a reasonable first step, it doesn’t fully meet the obligations of ensuring equality and diversity. It is crucial to take into account the needs and preferences of all patients, regardless of their race, religion, gender, or any other characteristic. By doing so, healthcare providers can ensure that their policies and practices are inclusive and accessible to everyone.

Sodium valproate is known to inhibit enzymes, which can lead to an increase in warfarin levels if taken together. The patient’s medical history could include any of the listed drugs, but the question is specifically testing knowledge of enzyme inhibitors. Rifampicin and St John’s Wort are both enzyme inducers, while heroin (diamorphine) doesn’t have any effect on enzyme activity.

P450 Enzyme System and its Inducers and Inhibitors

The P450 enzyme system is responsible for metabolizing many drugs in the body. Induction of this system occurs when a drug or substance causes an increase in the activity of the P450 enzymes. This process usually requires prolonged exposure to the inducing drug. On the other hand, P450 inhibitors decrease the activity of the enzymes and their effects are often seen rapidly.

Some common inducers of the P450 system include antiepileptics like phenytoin and carbamazepine, barbiturates such as phenobarbitone, rifampicin, St John’s Wort, chronic alcohol intake, griseofulvin, and smoking. Smoking affects CYP1A2, which is the reason why smokers require more aminophylline.

In contrast, some common inhibitors of the P450 system include antibiotics like ciprofloxacin and erythromycin, isoniazid, cimetidine, omeprazole, amiodarone, allopurinol, imidazoles such as ketoconazole and fluconazole, SSRIs like fluoxetine and sertraline, ritonavir, sodium valproate, acute alcohol intake, and quinupristin.

It is important to be aware of the potential for drug interactions when taking medications that affect the P450 enzyme system. Patients should always inform their healthcare provider of all medications and supplements they are taking to avoid any adverse effects.

Ectopic Pregnancy and Contraception

According to the FSRH, a previous ectopic pregnancy is not an absolute contraindication to the use of intrauterine methods of contraception. In fact, the overall risk of ectopic pregnancy is reduced with the use of IUC when compared to using no contraception. However, if pregnancy does occur with an intrauterine method in situ, the risk of an ectopic pregnancy occurring is increased. In some studies, half of the pregnancies that occurred were ectopic.

It is important to note that older editions of an Australian primary care textbook list an ectopic pregnancy as a contraindication. However, the latest FSRH advice is the reference on which the RCGP is likely to base their answers. Therefore, healthcare professionals should follow the most up-to-date guidelines when considering contraception options for patients with a history of ectopic pregnancy.

Understanding Tennis Elbow

Tennis elbow, also known as lateral epicondylitis, is a condition caused by overuse or strain of the extensor muscles in the forearm. It is most commonly seen in individuals in their fourth decade of life. Symptoms include pain in the lateral epicondyle region during resisted extension of the fingers and wrist.

Management of tennis elbow involves reducing strenuous activity for at least six weeks, with or without the use of a wrist splint. Local injection with corticosteroid and anaesthetic agents may also be an option. Surgical treatment is only considered for those with persistent symptoms that do not respond to other forms of treatment.

Eligibility for Free NHS Care

The rules for receiving free NHS care can be complex and detailed, but in general, patients from the European Economic Area (EEA), certain Commonwealth countries, and Ukraine are entitled to free healthcare. Additionally, there is a list of procedures and consultations, such as family planning, that are also covered under free healthcare.

If a patient has been accepted for permanent residence, they are not charged for NHS care, regardless of their home country. It is important to note that eligibility for free NHS care can vary depending on individual circumstances, so it is always best to check with the NHS or a healthcare professional to confirm eligibility.

In cases of iron-deficiency anemia, it is common for both the total iron-binding capacity (TIBC) and transferrin levels to be elevated. However, it should be noted that the transferrin saturation level is typically decreased.

Iron deficiency anaemia is a prevalent condition worldwide, with preschool-age children being the most affected. The lack of iron in the body leads to a decrease in red blood cells and haemoglobin, resulting in anaemia. The primary causes of iron deficiency anaemia are excessive blood loss, inadequate dietary intake, poor intestinal absorption, and increased iron requirements. Menorrhagia is the most common cause of blood loss in pre-menopausal women, while gastrointestinal bleeding is the most common cause in men and postmenopausal women. Vegans and vegetarians are more likely to develop iron deficiency anaemia due to the lack of meat in their diet. Coeliac disease and other conditions affecting the small intestine can prevent sufficient iron absorption. Children and pregnant women have increased iron demands, and the latter may experience dilution due to an increase in plasma volume.

The symptoms of iron deficiency anaemia include fatigue, shortness of breath on exertion, palpitations, pallor, nail changes, hair loss, atrophic glossitis, post-cricoid webs, and angular stomatitis. To diagnose iron deficiency anaemia, a full blood count, serum ferritin, total iron-binding capacity, transferrin, and blood film tests are performed. Endoscopy may be necessary to rule out malignancy, especially in males and postmenopausal females with unexplained iron-deficiency anaemia.

The management of iron deficiency anaemia involves identifying and treating the underlying cause. Oral ferrous sulfate is commonly prescribed, and patients should continue taking iron supplements for three months after the iron deficiency has been corrected to replenish iron stores. Iron-rich foods such as dark-green leafy vegetables, meat, and iron-fortified bread can also help. It is crucial to exclude malignancy by taking an adequate history and appropriate investigations if warranted.

Approximately 50% of individuals diagnosed with BPPV will experience a relapse of symptoms within 3 to 5 years.

Benign paroxysmal positional vertigo (BPPV) is a common cause of vertigo that occurs suddenly when there is a change in head position. It is more prevalent in individuals over the age of 55 and is less common in younger patients. Symptoms of BPPV include dizziness and vertigo, which can be accompanied by nausea. Each episode typically lasts for 10-20 seconds and can be triggered by rolling over in bed or looking upwards. A positive Dix-Hallpike manoeuvre, which is indicated by vertigo and rotatory nystagmus, can confirm the diagnosis of BPPV.

Fortunately, BPPV has a good prognosis and usually resolves on its own within a few weeks to months. Treatment options include the Epley manoeuvre, which is successful in around 80% of cases, and vestibular rehabilitation exercises such as the Brandt-Daroff exercises. While medication such as Betahistine may be prescribed, it tends to have limited effectiveness. However, it is important to note that around half of individuals with BPPV may experience a recurrence of symptoms 3-5 years after their initial diagnosis.

The use of ondansetron during pregnancy has been associated with an increased risk of 3 oral clefts per 10,000 births, according to a study. However, this risk is not included in the RCOG guideline on nausea and vomiting of pregnancy, and there is no official NICE guidance on the matter. A draft of NICE’s antenatal care guidance suggests that ondansetron may increase the chance of a baby being born with a cleft lip or palate, but there are no recognised risks for the mother or newborn. Claims of a risk of spontaneous miscarriage in twin pregnancies or severe congenital heart defects in newborns are not supported by current evidence.

Hyperemesis gravidarum is a severe form of nausea and vomiting that affects around 1% of pregnancies. It is usually experienced between 8 and 12 weeks of pregnancy but can persist up to 20 weeks. The condition is thought to be related to raised beta hCG levels and is more common in women who are obese, nulliparous, or have multiple pregnancies, trophoblastic disease, or hyperthyroidism. Smoking is associated with a decreased incidence of hyperemesis.

The Royal College of Obstetricians and Gynaecologists recommend that a woman must have a 5% pre-pregnancy weight loss, dehydration, and electrolyte imbalance before a diagnosis of hyperemesis gravidarum can be made. Validated scoring systems such as the Pregnancy-Unique Quantification of Emesis (PUQE) score can be used to classify the severity of NVP.

Management of hyperemesis gravidarum involves using antihistamines as a first-line treatment, with oral cyclizine or oral promethazine being recommended by Clinical Knowledge Summaries. Oral prochlorperazine is an alternative, while ondansetron and metoclopramide may be used as second-line treatments. Ginger and P6 (wrist) acupressure can be tried, but there is little evidence of benefit. Admission may be needed for IV hydration.

Complications of hyperemesis gravidarum can include Wernicke’s encephalopathy, Mallory-Weiss tear, central pontine myelinolysis, acute tubular necrosis, and fetal growth restriction, preterm birth, and cleft lip/palate (if ondansetron is used during the first trimester). The NICE Clinical Knowledge Summaries recommend considering admission if a woman is unable to keep down liquids or oral antiemetics, has ketonuria and/or weight loss (greater than 5% of body weight), or has a confirmed or suspected comorbidity that may be adversely affected by nausea and vomiting.
