The BNF cautions that the use of short-acting versions of nifedipine can result in significant fluctuations in blood pressure and trigger reflex tachycardia.

Calcium channel blockers are a class of drugs commonly used to treat cardiovascular disease. These drugs target voltage-gated calcium channels found in myocardial cells, cells of the conduction system, and vascular smooth muscle. The different types of calcium channel blockers have varying effects on these areas, making it important to differentiate their uses and actions.

Verapamil is used to treat angina, hypertension, and arrhythmias. It is highly negatively inotropic and should not be given with beta-blockers as it may cause heart block. Side effects include heart failure, constipation, hypotension, bradycardia, and flushing.

Diltiazem is used to treat angina and hypertension. It is less negatively inotropic than verapamil, but caution should still be exercised when patients have heart failure or are taking beta-blockers. Side effects include hypotension, bradycardia, heart failure, and ankle swelling.

Nifedipine, amlodipine, and felodipine are dihydropyridines used to treat hypertension, angina, and Raynaud’s. They affect peripheral vascular smooth muscle more than the myocardium, which means they do not worsen heart failure but may cause ankle swelling. Shorter acting dihydropyridines like nifedipine may cause peripheral vasodilation, resulting in reflex tachycardia. Side effects include flushing, headache, and ankle swelling.

According to current NICE guidelines, the management of hypertension involves a flow chart that takes into account various factors such as age, ethnicity, and comorbidities. Calcium channel blockers may be used as part of the treatment plan depending on the individual patient’s needs.

Detecting Ovarian Cancer: A Challenging Diagnosis

Detecting ovarian cancer can be a challenging diagnosis as the symptoms are often vague, especially in the early stages of the disease. However, there are certain risk factors and cardinal symptoms that can help in identifying the disease. Women with a family history of breast cancer, carriers of the BRCA1 and BRCA2 gene, and Polish women are at an increased risk of ovarian cancer. Patients presenting with persistent bloating, abdominal or pelvic pain, and difficulty in eating or fullness after eating small quantities of food should be evaluated for ovarian cancer.

NICE recommends that women over the age of 50 who have one or more symptoms associated with ovarian cancer occurring more than 12 times a month or for more than a month should be offered CA125 testing. If the CA125 is 35 IU/mL or greater, an urgent ultrasound scan of the pelvis should be arranged. Therefore, performing a pelvic examination and arranging testing for CA125 is the most appropriate way forward for patients with symptoms suggestive of ovarian cancer. Early detection and prompt treatment can improve the prognosis of ovarian cancer.

Understanding ADHD: Symptoms and Diagnosis

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by symptoms of hyperactivity, impulsivity, and/or inattention. These symptoms should be present in multiple settings, such as both at home and in school, and in multiple domains of social or personal functioning. ADHD is typically diagnosed in 3-7% of school-age children.

It is important to note that a carefree attitude to danger alone is not enough to make a diagnosis of ADHD. Evidence of impairment in other domains is necessary. Additionally, while environmental factors may play a role, genetics are also believed to be involved in the development of ADHD. Therefore, it is possible for a sibling or other family member to also have the disorder.

According to NICE guidelines, symptoms must be present for at least six months for a diagnosis of ADHD. Poor academic achievement alone is not enough to indicate ADHD, as it is commonly seen in children without the disorder. It is important to consider a range of symptoms and domains of functioning when evaluating for ADHD.

Women who have taken ulipristal acetate should wait for 5 days before starting regular hormonal contraception. This is because ulipristal may reduce the effectiveness of hormonal contraception. This advice applies to all hormonal contraception methods, including the pill, patch, or ring.

Barrier methods should be used during the 5-day waiting period before starting the COCP to ensure its effectiveness. If the patient is starting the COCP within the first 5 days of her cycle, barrier methods may not be necessary.

Based on the information provided, there is no reason why the patient cannot be prescribed the COCP. Alternative contraception is not required if the patient prefers the COCP.

It is not necessary to wait until the start of the next cycle before taking the pill, as long as barrier methods are used for 7 days.

Emergency contraception is available in the UK through two methods: emergency hormonal contraception and intrauterine device (IUD). Emergency hormonal contraception includes two types of pills: levonorgestrel and ulipristal. Levonorgestrel works by stopping ovulation and inhibiting implantation, and should be taken as soon as possible after unprotected sexual intercourse (UPSI) for maximum efficacy. The single dose of levonorgestrel is 1.5mg, but should be doubled for those with a BMI over 26 or weight over 70kg. It is safe and well-tolerated, but may cause vomiting in around 1% of women. Ulipristal, on the other hand, is a selective progesterone receptor modulator that inhibits ovulation. It should be taken within 120 hours after intercourse, and may reduce the effectiveness of hormonal contraception. The most effective method of emergency contraception is the copper IUD, which may inhibit fertilization or implantation. It must be inserted within 5 days of UPSI, or up to 5 days after the likely ovulation date. Prophylactic antibiotics may be given if the patient is at high-risk of sexually transmitted infection. The IUD is 99% effective regardless of where it is used in the cycle, and may be left in-situ for long-term contraception.

Indications for Surgical Repair of Hiatus Hernia

Indications for surgical repair of hiatus hernia include recurrent respiratory tract infection due to reflux. It is also considered in patients who have a para-oesophageal hernia because of the risk of strangulation.

Given this patient’s young age and the fact that he has attended twice in six months with symptoms of respiratory tract infection, surgical referral for laparoscopic fundoplication is advised. This procedure can help alleviate symptoms of reflux and prevent further respiratory tract infections. It is important to consider surgical intervention in cases where conservative management has failed or when there is a risk of complications such as strangulation. Proper evaluation and management of hiatus hernia can improve the quality of life for patients and prevent potential complications.

HPV Testing in Cervical Screening

The use of HPV testing in cervical screening has been studied to determine if it can improve the accuracy of identifying women who need further investigation and treatment. Currently, only a small percentage of women referred for colposcopy actually require treatment as low-grade abnormalities often resolve on their own. By incorporating HPV testing, women with borderline or mild dyskaryosis who test negative for high-risk HPV can simply return to routine screening recall, while those who test positive are referred for colposcopy.

HPV testing is also used as a test of cure for women who have been treated for cervical intraepithelial neoplasia. Those with normal, borderline, or mild dyskaryosis smear results who are HPV negative can return to three-yearly recall. This approach ensures that women receive appropriate follow-up care while minimizing unnecessary referrals and treatments. Overall, the use of HPV testing in cervical screening has the potential to improve the accuracy and efficiency of the screening process.

Hib Vaccine: Protection Against Invasive Haemophilus Disease

The Hib vaccine is a conjugated polysaccharide vaccine that is given in a course of three doses at monthly intervals to infants at two, three, and four months of age, along with other routine vaccinations. A single dose is effective for children over 13 months of age. However, it is only given after 10 years of age to those children who are at increased risk of invasive Haemophilus disease, such as those with sickle cell disease, undergoing antineoplastic therapy, or with an absent spleen. Although highly effective, vaccination failures have been reported.

Unlike influenza vaccines, hypersensitivity to egg is not a contraindication to Hib. However, evidence of a previous anaphylactic reaction contraindicates the use of the MMR and yellow fever vaccines. The Hib vaccine offers protection against the capsulated form of Hib that causes meningitis, acute epiglottitis, pneumonia, septic arthritis, and cellulitis. Overall, the Hib vaccine is an important tool in preventing invasive Haemophilus disease in children.

Cataract as a Cause of Reduced Acuity

A patient with reduced acuity that improves with pinhole may have a refractive error caused by cataract. If the red reflex is duller in one eye, cataract in that eye should be considered as a possible diagnosis. Cataracts that significantly affect quality of life should be referred to ophthalmology for evaluation of cataract surgery and future visual rehabilitation.

It is important to note that referral guidance may vary by region, but for the purpose of examination questions, candidates should answer based on national consensus opinion.

Assessing the Severity of Dehydration in Young Children

When evaluating the likelihood of serious illness in young children, reduced skin turgor is the only red (high risk) option according to National Institute for Health and Care Excellence guidelines. Poor feeding, apex rate of 160 per minute, dry mucous membrane, and reduced urine output are all amber signs (intermediate risk) that require careful monitoring and safety netting. The pinch test (skin turgor) is the most reliable clinical assessment of dehydration when used alongside other clinical indicators. While these amber signs may not necessitate admission, they do require stringent safety netting and review.

DVLA guidance after angioplasty – refrain from driving for a period of 7 days.

DVLA Guidelines for Cardiovascular Disorders and Driving

The DVLA has specific guidelines for individuals with cardiovascular disorders who wish to drive a car or motorcycle. For those with hypertension, driving is permitted unless the treatment causes unacceptable side effects, and there is no need to notify the DVLA. However, if the individual has Group 2 Entitlement, they will be disqualified from driving if their resting blood pressure consistently measures 180 mmHg systolic or more and/or 100 mm Hg diastolic or more.

Individuals who have undergone elective angioplasty must refrain from driving for one week, while those who have undergone CABG or acute coronary syndrome must wait four weeks before driving. If an individual experiences angina symptoms at rest or while driving, they must cease driving altogether. Pacemaker insertion requires a one-week break from driving, while implantable cardioverter-defibrillator (ICD) implantation results in a six-month driving ban if implanted for sustained ventricular arrhythmia. If implanted prophylactically, the individual must cease driving for one month, and Group 2 drivers are permanently barred from driving with an ICD.

Successful catheter ablation for an arrhythmia requires a two-day break from driving, while an aortic aneurysm of 6 cm or more must be reported to the DVLA. Licensing will be permitted subject to annual review, but an aortic diameter of 6.5 cm or more disqualifies patients from driving. Finally, individuals who have undergone a heart transplant must refrain from driving for six weeks, but there is no need to notify the DVLA.

Lamotrigine therapy is associated with a rare but acknowledged adverse effect.

Lamotrigine is a medication that is primarily used as an antiepileptic drug. It is typically prescribed as a second-line treatment for a range of generalised and partial seizures. The drug works by blocking sodium channels in the body, which helps to reduce the occurrence of seizures.

Despite its effectiveness in treating seizures, lamotrigine can also cause a number of adverse effects. One of the most serious of these is Stevens-Johnson syndrome, a rare but potentially life-threatening skin condition. Other possible side effects of the drug include dizziness, headache, nausea, and blurred vision. It is important for patients taking lamotrigine to be aware of these potential risks and to report any unusual symptoms to their healthcare provider.

If a patient with COPD continues to smoke, it is not advisable to provide them with azithromycin prophylaxis. Instead, they should be offered smoking cessation. The use of high-dose inhaled corticosteroids is no longer recommended due to the increased risk of infections such as pneumonia. Long-term oral corticosteroids should only be used at low doses and on the advice of the respiratory team. Beta-carotene supplements are not recommended for the management of COPD due to limited evidence of their effectiveness.

The National Institute for Health and Care Excellence (NICE) updated its guidelines on the management of chronic obstructive pulmonary disease (COPD) in 2018. The guidelines recommend general management strategies such as smoking cessation advice, annual influenza vaccination, and one-off pneumococcal vaccination. Pulmonary rehabilitation is also recommended for patients who view themselves as functionally disabled by COPD.

Bronchodilator therapy is the first-line treatment for patients who remain breathless or have exacerbations despite using short-acting bronchodilators. The next step is determined by whether the patient has asthmatic features or features suggesting steroid responsiveness. NICE suggests several criteria to determine this, including a previous diagnosis of asthma or atopy, a higher blood eosinophil count, substantial variation in FEV1 over time, and substantial diurnal variation in peak expiratory flow.

If the patient doesn’t have asthmatic features or features suggesting steroid responsiveness, a long-acting beta2-agonist (LABA) and long-acting muscarinic antagonist (LAMA) should be added. If the patient is already taking a short-acting muscarinic antagonist (SAMA), it should be discontinued and switched to a short-acting beta2-agonist (SABA). If the patient has asthmatic features or features suggesting steroid responsiveness, a LABA and inhaled corticosteroid (ICS) should be added. If the patient remains breathless or has exacerbations, triple therapy (LAMA + LABA + ICS) should be offered.

NICE only recommends theophylline after trials of short and long-acting bronchodilators or to people who cannot use inhaled therapy. Azithromycin prophylaxis is recommended in select patients who have optimised standard treatments and continue to have exacerbations. Mucolytics should be considered in patients with a chronic productive cough and continued if symptoms improve.

Cor pulmonale features include peripheral oedema, raised jugular venous pressure, systolic parasternal heave, and loud P2. Loop diuretics should be used for oedema, and long-term oxygen therapy should be considered. Smoking cessation, long-term oxygen therapy in eligible patients, and lung volume reduction surgery in selected patients may improve survival in patients with stable COPD. NICE doesn’t recommend the use of ACE-inhibitors, calcium channel blockers, or alpha blockers

Preventing Nosocomial Infections in Hospitals: Identification, Control, and Measures

Insufficient hand disinfection is the leading cause of wound infections acquired in hospitals. The primary objective of hospital infection control is to prevent nosocomial infections. To achieve this, clinical and epidemiological investigations must first identify hospital-acquired infections as either endemic or epidemic. Identifying and typing the isolates causing nosocomial infections can help recognize organisms that are epidemiologically linked. Invasive multiresistant organisms, such as MRSA, often require infection-control measures to prevent their spread, which can minimize the use of expensive and sometimes toxic antibiotics required for their prophylaxis and treatment.

Epidemic outbreaks can be controlled by measures that interrupt the spread of infection, such as the use of gowns, gloves, and careful hand-washing by those attending patients. Transfer of colonized or infected patients to a single room or an isolation ward is a physical means of preventing spread. Patients infected with the same organism can be grouped together and attended to by a cohort of nurses not involved with uninfected patients. Identification of additional carriers and elimination of colonization may be necessary for some epidemic outbreaks. Although controlled trials demonstrating the efficacy of such measures have not been performed, many observational studies support their use.

Understanding Thrombophilias: Factor V Leiden Mutation and Other Genetic Risk Factors for DVT

Deep-vein thrombosis (DVT) is a serious medical condition that can be caused by a variety of risk factors, including heritable thrombophilias. These genetic conditions can be identified in up to 50% of venous thromboemboli cases, and the most common heritable thrombophilia in Caucasians is the Factor V Leiden mutation. This autosomal-dominant condition affects around 5% of the population and increases the risk of thrombosis three to eight times, depending on the individual’s genotype. Other genetic risk factors for DVT include protein C and protein S deficiencies, which are less common than Factor V Leiden mutation. It is important to consider these genetic risk factors when evaluating patients with DVT, especially those with a family history of hormone-associated VTE or without other traditional risk factors for thrombosis. Understanding thrombophilias can help clinicians make informed decisions about treatment and prevention strategies for DVT.

This man is experiencing heart failure due to ischaemic heart disease, which is a leading cause of death among men in the UK. Beta-blockers are the only medication proven to reduce all-cause mortality in patients with heart failure with reduced ejection fraction, and they can also help control hypertension. However, before starting treatment, his blood pressure and pulse should be checked to ensure that he is not at risk of bradycardia or hypotension. Spironolactone is not recommended for improving mortality in heart failure patients, but it can be used to treat hypertension and oedema. U&Es should be monitored regularly to avoid renal function deterioration and hyperkalaemia. Amlodipine and furosemide have not been shown to improve mortality in heart failure patients, but they can be used to control hypertension and oedema, respectively. U&Es should also be monitored regularly when using these medications. Ramipril has been shown to reduce hospital admissions in heart failure patients, but it can impair renal function and cause hyperkalaemia. U&Es should be checked regularly, and the medication should not be initiated if the patient’s potassium level is too high. Patients should also be advised to stop taking ramipril during diarrhoea or vomiting illnesses to avoid dehydration and acute kidney injury.

This patient has a condition called septal hematoma, which can lead to a hole in the septum if not treated promptly. This happens because the hematoma restricts blood flow to the cartilage and can become infected. To diagnose this condition, a doctor will use a nasal speculum or otoscope to look for asymmetry and swelling in the septum. They may also need to feel the septum with a gloved finger. Septal hematoma is usually caused by significant facial trauma in adults, but even minor nasal trauma can cause it in children. If a child has this condition, it may be a sign of abuse. Immediate drainage under anesthesia is necessary to prevent long-term damage.

Individuals diagnosed with schizophrenia are prohibited from driving and are required to inform the DVLA. They may resume driving with a Group 1 license only after being stable and well for three months, as confirmed by a suitable psychiatric report. The DVLA guidelines specify that patients with schizophrenia can drive if they meet certain criteria, including maintaining stability for at least three months, complying with their treatment plan, regaining insight, being free from medication side effects that could impair driving, and receiving a positive specialist report.

The DVLA has specific rules regarding psychiatric disorders for those who wish to drive group 1 vehicles such as cars and motorcycles. Those with severe anxiety or depression accompanied by memory problems, concentration problems, agitation, behavioral disturbance, or suicidal thoughts must not drive and must inform the DVLA. Those with acute psychotic disorder, hypomania or mania, or schizophrenia must not drive during acute illness and must notify the DVLA. Those with pervasive developmental disorders and ADHD may be able to drive but must inform the DVLA. Those with mild cognitive impairment, dementia, or mild learning disability may be able to drive but must inform the DVLA. Those with severe disability must not drive and must notify the DVLA. Those with personality disorders may be able to drive but must inform the DVLA. The rules for group 2 vehicles such as buses and lorries are stricter.

Understanding Human Papillomavirus (HPV) and its Association with Cancer

Human papillomavirus (HPV) is a virus that infects the skin and mucosae of the upper respiratory and anogenital tracts. With about 100 types of HPV, 40 of them infect the genital tract. HPV is classified as either ‘high-risk’ or ‘low-risk’ types, depending on their association with cancer. HPV16 is responsible for over 50% of all cervical cancers, while HPV18 is responsible for over 15%. Although most high-risk infections are transient and cause no clinical problems, persistent infection by a high-risk HPV type is the most important factor for the development of cancer. Types 6 and 11 are associated with anogenital warts and are included in one of the HPV vaccines (Gardasil®) along with types 16 and 18. It is recommended that individuals receive the HPV vaccine to prevent the development of cancer.

Bladder Cancer Risk Factors

Understanding the risk factors associated with bladder cancer is crucial for early detection and prevention. While family history may be a concern for some, lifestyle and environmental factors play a more significant role in the majority of cases. Smoking, for instance, is responsible for 37% of bladder cancers, with smokers being 3.8 times more likely to develop the disease than non-smokers. A family history of bladder cancer in a first-degree relative increases the risk by 1.8 times, while HPV infection is associated with a 2.8 times higher risk. Obesity, with a body mass index of 30 or more, can cause a 9% higher risk of developing bladder cancer than in someone of healthy weight. However, alcohol consumption has not been shown to be a risk factor. Additionally, occupational and environmental factors can also increase the risk of bladder cancer. For more information on these factors, Cancer Research UK provides a useful resource on bladder cancer risk factors.

Management of Cervical Spondylosis: A Wait-and-See Approach with Analgesia

Cervical spondylosis is a common condition among middle-aged patients, characterized by osteophyte formation and disc space narrowing. While there is little robust evidence to support many of the commonly used treatments, most general practitioners will employ a wait-and-see strategy, expecting a favourable outcome. This approach can be supported by simple analgesia with paracetamol and ibuprofen. Prolonged absence from work should be discouraged.

A cervical collar is not recommended as it restricts mobility and may prolong symptoms. Similarly, an X-ray is likely to be unhelpful in most cases. However, doctors should be alert for features suggesting serious spinal pathology and refer patients to a pain clinic if symptoms are prolonged.

Physiotherapy may be appropriate for stretching and strengthening exercises and manual therapy, but referral should be based on the duration of symptoms. While acute neck pain has a good prognosis for the majority of patients, a relatively high proportion of patients still report neck pain after one year of follow-up. Therefore, a wait-and-see approach with analgesia is a reasonable first-line management strategy for cervical spondylosis.

Understanding Acute Opioid Toxicity

Acute opioid toxicity is a serious condition that can result in drowsiness, nausea, vomiting, and respiratory depression. The severity of symptoms may be exacerbated if alcohol or other sedatives are also involved. Hypotension is a common occurrence, and both tachycardia and bradycardia may be observed. Hypoventilation can lead to hypoxia-induced cardiac arrhythmias, and pinpoint pupils may be present. Sweating is more commonly associated with acute opioid withdrawal. It is important to seek medical attention immediately if you suspect acute opioid toxicity.

Diagnosing Optic Nerve Lesions: A Guide

When a patient presents with impaired colour appreciation and a relative afferent pupillary defect, an acute optic nerve lesion is likely. In younger patients, optic neuritis due to demyelination is the most common cause. Fundoscopy may reveal a swollen optic nerve head in the acute stage. Hemianopic visual disturbance is more commonly seen in cerebral infarction, while optic nerve glioma typically presents over a longer period with proptosis. Migraine can cause transient monocular visual disturbances, often accompanied by headache. Temporal arteritis is rare in patients under 50.

Characteristics of Melanoma: The ABCDE Mnemonic

Melanoma is a type of skin cancer that can be deadly if not detected and treated early. To help identify potential melanomas, dermatologists use the ABCDE mnemonic. Each letter represents a characteristic that may indicate the presence of melanoma.

A stands for asymmetry. If one half of a mole or lesion doesn’t match the other half, it may be a sign of melanoma. B is for border irregularity. Melanomas often have uneven or jagged edges. C represents color variegation. Melanomas may have multiple colors or shades within the same lesion. D is for diameter. Melanomas are typically larger than a pencil eraser, but any mole or lesion that is 6mm or more in diameter should be examined by a dermatologist. Finally, E stands for evolution. Any changes in size, shape, or color of a mole or lesion should be monitored closely.

By remembering the ABCDE mnemonic, individuals can be more aware of the characteristics of melanoma and seek medical attention if they notice any concerning changes in their skin.

The DVLA has stringent rules in place for individuals with ICDs. They are prohibited from driving a group 1 vehicle for a period of 6 months following the insertion of an ICD or after experiencing an ICD shock. Furthermore, they are permanently disqualified from obtaining a group 2 HGV license.

DVLA Guidelines for Cardiovascular Disorders and Driving

The DVLA has specific guidelines for individuals with cardiovascular disorders who wish to drive a car or motorcycle. For those with hypertension, driving is permitted unless the treatment causes unacceptable side effects, and there is no need to notify the DVLA. However, if the individual has Group 2 Entitlement, they will be disqualified from driving if their resting blood pressure consistently measures 180 mmHg systolic or more and/or 100 mm Hg diastolic or more.

Individuals who have undergone elective angioplasty must refrain from driving for one week, while those who have undergone CABG or acute coronary syndrome must wait four weeks before driving. If an individual experiences angina symptoms at rest or while driving, they must cease driving altogether. Pacemaker insertion requires a one-week break from driving, while implantable cardioverter-defibrillator (ICD) implantation results in a six-month driving ban if implanted for sustained ventricular arrhythmia. If implanted prophylactically, the individual must cease driving for one month, and Group 2 drivers are permanently barred from driving with an ICD.

Successful catheter ablation for an arrhythmia requires a two-day break from driving, while an aortic aneurysm of 6 cm or more must be reported to the DVLA. Licensing will be permitted subject to annual review, but an aortic diameter of 6.5 cm or more disqualifies patients from driving. Finally, individuals who have undergone a heart transplant must refrain from driving for six weeks, but there is no need to notify the DVLA.

Loop diuretics should be used for oedema, and long-term oxygen therapy should be considered. Smoking cessation, long-term oxygen therapy in eligible patients, and lung volume reduction surgery in selected patients may improve survival in patients with stable COPD. NICE doesn’t recommend the use of ACE-inhibitors, calcium channel blockers, or alpha blockers

Common Skin Conditions and Their Characteristics

Necrobiosis Lipoidica Diabeticorum: A rare skin condition that is more prevalent in diabetic patients. It is characterized by the development of yellowish-brown patches that slowly grow over several months. The center of the patch becomes pale and thin with telangiectasia. Lesions can occur on various parts of the body, but the most common site is pretibial. Trauma can cause ulceration, and no treatment has proven to be completely effective.

Lichen Sclerosus: Usually found in the anogenital area of women and on the prepuce, glans, and coronal sulcus in men. Patches are white and thickened or crinkled like cigarette paper.

Erythema Nodosum: Presents as red, tender nodules on the anterior aspect of the lower leg. The nodules last for 3-6 weeks.

Granuloma Annulare: Typically found on the dorsa of the hands or feet, but can be more widespread. The disseminated form is characterized by skin-colored, pink, or mauve non-scaly papules arranged in rings 10 cm or more in diameter.

Venous Eczema: Itchy erythematous scaly or crusted patches on the lower legs. The patches may be confluent and circumferential, and there may be pigmentary changes due to haemosiderin deposition.

Characteristics of Common Skin Conditions

After giving birth, women need to use contraception after 21 days. The Progestogen-only pill (POP) can be started at any time postpartum, according to the FSRH. Additional contraception should be used for the first 2 days after day 21. A small amount of progestogen enters breast milk, but it is not harmful to the infant. On the other hand, the Combined oral contraceptive pill (COCP) is absolutely contraindicated (UKMEC 4) if breastfeeding is less than 6 weeks postpartum. If breastfeeding is between 6 weeks to 6 months postpartum, it is UKMEC 2. The COCP may reduce breast milk production in lactating mothers. It should not be used in the first 21 days due to the increased venous thromboembolism risk postpartum. After day 21, additional contraception should be used for the first 7 days.

The intrauterine device or intrauterine system can be inserted within 48 hours of childbirth or after 4 weeks. Meanwhile, the Lactational amenorrhoea method (LAM) is 98% effective if the woman is fully breastfeeding (no supplementary feeds), amenorrhoeic, and less than 6 months postpartum. It is important to note that an inter-pregnancy interval of less than 12 months between childbirth and conceiving again is associated with an increased risk of preterm birth, low birth weight, and small for gestational age babies.

Understanding Intussusception

Intussusception is a medical condition where one part of the bowel folds into the lumen of the adjacent bowel, usually around the ileocecal region. This condition is most common in infants between 6-18 months old, with boys being affected twice as often as girls. Symptoms of intussusception include severe, crampy abdominal pain, inconsolable crying, vomiting, and bloodstained stool, which is a late sign. During a paroxysm, the infant will draw their knees up and turn pale, and a sausage-shaped mass may be felt in the right upper quadrant.

To diagnose intussusception, ultrasound is now the preferred method of investigation, which may show a target-like mass. Treatment for intussusception involves reducing the bowel by air insufflation under radiological control, which is now widely used first-line compared to the traditional barium enema. If this method fails, or the child has signs of peritonitis, surgery is performed. Understanding the symptoms and treatment options for intussusception is crucial for parents and healthcare professionals to ensure prompt and effective management of this condition.

Registering Gifts as a GP

As a GP, it is important to register any gifts received from patients or their relatives that are worth £100 or more, unless the gift is unrelated to the provision of services. This applies to all GPs, including locums, and equivalent regulations operate throughout the UK. The register should include the name of the donor, nature of the gift, and its estimated value. CCGs may request to see these registers. GPs may also need to seek tax advice for declaring large gifts. It is recommended to contact your trade union or indemnity provider if unsure about any gift policy. Most practices have their own gift policy, so it is worth asking about this when joining a new practice.

Acute Epiglottitis and Croup: Two Respiratory Conditions in Children

Acute epiglottitis is a rare but life-threatening condition that causes inflammation of the epiglottis and surrounding soft tissues. It is most common in children between the ages of 2 and 8 and is often caused by Haemophilus influenza type b. Throat examination with a tongue depressor should be avoided, and urgent referral for laryngoscopy is necessary. Intubation may be required in over 30% of patients, and prophylactic intubation may be carried out in those with dyspnoea or stridor.

Croup, on the other hand, is a relatively mild and self-limiting condition that causes a barking cough and stridor. It is typically associated with viral upper respiratory infections and affects children between 6 months and 3 years of age. Symptoms are often worse at night.
