Patients suspected of having shingles should receive antiviral treatment within 72 hours of symptom onset, as this can help reduce the risk of post-herpetic complications. In the case of this patient, who is experiencing symptoms of shingles within the 72-hour window and has an immunosuppressive condition, antivirals such as aciclovir should be prescribed. Amitriptyline, which is used to manage post-herpetic neuralgia, would not be appropriate at this stage. Chlorphenamine is typically used to manage itching associated with chickenpox, but as this patient is only experiencing symptoms in one dermatome, it is more likely to be shingles. Flucloxacillin, an antibiotic used to treat bacterial skin infections, would not be appropriate in this case as the patient’s symptoms are consistent with herpes zoster infection.

Shingles is a painful blistering rash caused by reactivation of the varicella-zoster virus. It is more common in older individuals and those with immunosuppressive conditions. The rash is well demarcated by the affected dermatome and may be accompanied by fever and lethargy. Treatment includes analgesia, antivirals, and potentially oral corticosteroids. Complications include post-herpetic neuralgia, ocular and ear complications. Antivirals should be used within 72 hours to reduce the risk of post-herpetic neuralgia.

The correct initial step for paediatric basic life support (BLS) is to give 5 rescue breaths immediately, even before checking for a pulse. This is because respiratory causes are the most common in children. Checking for a femoral pulse is not necessary to determine the need for chest compressions, as palpation of the pulse is not a reliable indicator of effective circulation. Giving 2 rescue breaths is incorrect for children, as they require 5 rescue breaths to mitigate hypoxia. The correct ratio of chest compressions to rescue breaths is 15:2, but the first step in paediatric BLS is always to give 5 rescue breaths.

Paediatric Basic Life Support Guidelines

Paediatric basic life support guidelines were updated in 2015 by the Resuscitation Council. Lay rescuers should use a compression:ventilation ratio of 30:2 for children under 1 year and between 1 year and puberty, a child is defined. If there are two or more rescuers, a ratio of 15:2 should be used.

The algorithm for paediatric basic life support starts with checking if the child is unresponsive and shouting for help. The airway should be opened, and breathing should be checked by looking, listening, and feeling for breaths. If the child is not breathing, five rescue breaths should be given, and signs of circulation should be checked.

For infants, the brachial or femoral pulse should be used, while children should use the femoral pulse. Chest compressions should be performed at a ratio of 15:2, with a rate of 100-120 compressions per minute for both infants and children. The depth of compressions should be at least one-third of the anterior-posterior dimension of the chest, which is approximately 4 cm for an infant and 5 cm for a child.

In children, the lower half of the sternum should be compressed, while in infants, a two-thumb encircling technique should be used for chest compressions. These guidelines are crucial for anyone who may need to perform basic life support on a child, and it is essential to follow them carefully to ensure the best possible outcome.

Anterior uveitis is a common manifestation of AS, occurring in 20-30% of patients, especially those who are HLA-B27 positive. Symptoms include a painful red eye, photophobia, increased lacrimation, and blurred vision. AACG, on the other hand, is characterized by sudden blockage of the anterior chamber angle, causing a sudden rise in intraocular pressure. It is less likely in this case as it is usually seen in patients over 60 years old and has no association with AS. Blepharitis, herpes zoster ophthalmicus, and keratoconus are also unlikely diagnoses as they have different symptoms and no association with AS.

Common Eye Conditions: Causes and Prevalence

Diabetes can lead to various ophthalmic complications, including glaucoma, cataracts, and neuropathies, but the most common and potentially blinding is diabetic retinopathy. This condition accounts for 12% of all new cases of blindness in developed countries and is the leading cause of new blindness in people aged 25-64 years. Glaucoma, a group of eye diseases that damage the optic nerve, is more prevalent in the aging population, with up to 15% affected by the seventh decade of life. Age-related macular degeneration (AMD) is the most common cause of irreversible vision loss in the developed world, with non-exudative (dry) AMD comprising more than 90% of patients diagnosed with AMD. Optic atrophy, a sign of many disease processes, can cause changes in the color and structure of the optic disc associated with variable degrees of visual dysfunction. Finally, corneal abrasion, caused by a disruption in the integrity of the corneal epithelium or physical external forces, is the most common eye injury. While most people recover fully from minor corneal abrasions, deeper scratches can cause long-term vision problems if not treated properly.

Managing Seizures: Basic Steps and Medication Dosages

Seizures can be a frightening experience for both the patient and those around them. While most seizures will stop on their own, prolonged seizures can be life-threatening. Therefore, it is important to know how to manage seizures in case of an emergency.

The first step in managing a seizure is to check the patient’s airway and provide oxygen if necessary. It is also important to place the patient in the recovery position to prevent choking or aspiration. If the seizure is prolonged, benzodiazepines may be necessary. The recommended dose for rectal diazepam varies depending on the patient’s age and condition. For neonates, the dose is 1.25-2.5 mg, while for adults, it is 10-20 mg (max. 30 mg). The dose may be repeated once after 10-15 minutes if necessary.

Another medication that may be used is midazolam oromucosal solution. However, it is important to note that this medication is unlicensed for use in neonates and children under 2 months old. The recommended dose for midazolam oromucosal solution also varies depending on the patient’s age and condition. For example, the dose for a child aged 1-4 years is 5 mg, while for an adult, it is 10 mg.

In summary, managing seizures involves basic steps such as checking the airway and placing the patient in the recovery position. If the seizure is prolonged, benzodiazepines such as rectal diazepam or midazolam oromucosal solution may be necessary. It is important to follow the recommended dosage based on the patient’s age and condition.

The patient’s symptoms suggest achalasia, as they have experienced difficulty swallowing both solids and liquids from the beginning.

Understanding Achalasia: Symptoms, Diagnosis, and Treatment

Achalasia is a medical condition characterized by the failure of oesophageal peristalsis and relaxation of the lower oesophageal sphincter (LOS) due to the degenerative loss of ganglia from Auerbach’s plexus. This results in a contracted LOS and a dilated oesophagus above it. It is a condition that typically presents in middle-age and is equally common in men and women.

The clinical features of achalasia include dysphagia of both liquids and solids, heartburn, regurgitation of food, and variation in the severity of symptoms. If left untreated, it may lead to cough, aspiration pneumonia, and even malignant change in a small number of patients. To diagnose achalasia, oesophageal manometry is considered the most important diagnostic test. It shows excessive LOS tone that doesn’t relax on swallowing. A barium swallow may also be used to show a grossly expanded oesophagus with a fluid level and a ‘bird’s beak’ appearance. A chest x-ray may reveal a wide mediastinum and fluid level.

The treatment of achalasia involves pneumatic (balloon) dilation, which is increasingly becoming the preferred first-line option. It is less invasive and has a quicker recovery time than surgery. However, patients should be a low surgical risk as surgery may be required if complications occur. Surgical intervention with a Heller cardiomyotomy should be considered if recurrent or persistent symptoms occur. In some cases, an intra-sphincteric injection of botulinum toxin may be used in patients who are a high surgical risk. Drug therapy, such as nitrates and calcium channel blockers, may also have a role but is limited by side-effects. Understanding the symptoms, diagnosis, and treatment of achalasia is crucial in managing this condition effectively.

To evaluate diabetic neuropathy in the feet, it is recommended to utilize a monofilament weighing 10 grams.

Diabetic foot disease is a significant complication of diabetes mellitus that requires regular screening. In 2015, NICE published guidelines on diabetic foot disease. The disease is caused by two main factors: neuropathy, which results in a loss of protective sensation, and peripheral arterial disease, which increases the risk of macro and microvascular ischaemia. Symptoms of diabetic foot disease include loss of sensation, absent foot pulses, reduced ankle-brachial pressure index (ABPI), intermittent claudication, calluses, ulceration, Charcot’s arthropathy, cellulitis, osteomyelitis, and gangrene. All patients with diabetes should be screened for diabetic foot disease at least once a year. Screening for ischaemia involves palpating for both the dorsalis pedis pulse and posterial tibial artery pulse, while screening for neuropathy involves using a 10 g monofilament on various parts of the sole of the foot. NICE recommends that patients be risk-stratified into low, moderate, and high-risk categories based on factors such as deformity, previous ulceration or amputation, renal replacement therapy, neuropathy, and non-critical limb ischaemia. Patients who are moderate or high-risk should be regularly followed up by their local diabetic foot centre.

Primary dysmenorrhoea is best treated with NSAIDs like mefenamic acid, which are the first line of treatment according to NICE guidelines. Paracetamol can be used if NSAIDs are not suitable, and a combination of both can be tried if NSAIDs alone are not effective. Hormonal options like the combined oral contraceptive pill can also be considered, but contraindications must be ruled out. The intrauterine device or copper coil is not recommended for this patient due to the risk of heavier bleeding. Instead, the intrauterine system or Mirena coil can be offered as an alternative option. While the IUS is the first-line treatment for menorrhagia, NSAIDs are the initial choice for primary dysmenorrhoea. It is important to consider the patient’s plans for conception when deciding on treatment options.

Dysmenorrhoea is a condition where women experience excessive pain during their menstrual period. There are two types of dysmenorrhoea: primary and secondary. Primary dysmenorrhoea affects up to 50% of menstruating women and is not caused by any underlying pelvic pathology. It usually appears within 1-2 years of the menarche and is thought to be partially caused by excessive endometrial prostaglandin production. Symptoms include suprapubic cramping pains that may radiate to the back or down the thigh, and pain typically starts just before or within a few hours of the period starting. NSAIDs such as mefenamic acid and ibuprofen are effective in up to 80% of women, and combined oral contraceptive pills are used second line for management.

Secondary dysmenorrhoea, on the other hand, typically develops many years after the menarche and is caused by an underlying pathology. The pain usually starts 3-4 days before the onset of the period. Causes of secondary dysmenorrhoea include endometriosis, adenomyosis, pelvic inflammatory disease, intrauterine devices, and fibroids. Clinical Knowledge Summaries recommend referring all patients with secondary dysmenorrhoea to gynaecology for investigation. It is important to note that the intrauterine system (Mirena) may help dysmenorrhoea, but this only applies to normal copper coils.

According to the GMC guidelines, sexual intercourse with children below the age of 13 cannot be considered consensual, and therefore, any sexual activity would be classified as rape. In such cases, breaking confidentiality is mandatory.

Guidelines for Obtaining Consent in Children

The General Medical Council has provided guidelines for obtaining consent in children. According to these guidelines, young people who are 16 years or older can be treated as adults and are presumed to have the capacity to make decisions. However, for children under the age of 16, their ability to understand what is involved determines whether they have the capacity to decide. If a competent child refuses treatment, a person with parental responsibility or the court may authorize investigation or treatment that is in the child’s best interests.

When it comes to providing contraceptives to patients under 16 years of age, the Fraser Guidelines must be followed. These guidelines state that the young person must understand the professional’s advice, cannot be persuaded to inform their parents, is likely to begin or continue having sexual intercourse with or without contraceptive treatment, and will suffer physical or mental health consequences without contraceptive treatment. Additionally, the young person’s best interests require them to receive contraceptive advice or treatment with or without parental consent.

Some doctors use the term Fraser competency when referring to contraception and Gillick competency when referring to general issues of consent in children. However, rumors that Victoria Gillick removed her permission to use her name or applied copyright have been debunked. It is important to note that in Scotland, those with parental responsibility cannot authorize procedures that a competent child has refused.

The recommended first-line treatment for menorrhagia is the intra-uterine system (IUS), which has a high success rate in stopping bleeding and only requires one insertion procedure. Additionally, it provides reliable contraception. Conversely, the copper coil may exacerbate menorrhagia symptoms. While medication such as the progesterone-only pill or combined oral contraceptive pill can be used, they are not the first choice. It would be an extreme measure to refer a woman of child-bearing age for a hysterectomy, especially when there are less invasive and reversible options available to treat menorrhagia, even if the patient expresses no desire for children.

Managing Heavy Menstrual Bleeding

Heavy menstrual bleeding, also known as menorrhagia, is a condition where a woman experiences excessive blood loss during her menstrual cycle. While it was previously defined as total blood loss of over 80 ml per cycle, the management of menorrhagia now depends on the woman’s perception of what is excessive. In the past, hysterectomy was a common treatment for heavy periods, but the approach has changed significantly since the 1990s.

To manage menorrhagia, a full blood count should be performed in all women. If symptoms suggest a structural or histological abnormality, a routine transvaginal ultrasound scan should be arranged. For women who do not require contraception, mefenamic acid or tranexamic acid can be used. If there is no improvement, other drugs can be tried while awaiting referral.

For women who require contraception, options include the intrauterine system (Mirena), combined oral contraceptive pill, and long-acting progestogens. Norethisterone can also be used as a short-term option to rapidly stop heavy menstrual bleeding. The flowchart below shows the management of menorrhagia.
