Pregnancy poses a challenge when it comes to treating acne as many treatments can be harmful to the developing foetus. It is important to consider this issue before starting any treatment, especially in women of childbearing age who may not yet know they are pregnant.

Retinoids, such as isotretinoin and adapalene, are not safe for use during pregnancy due to their teratogenic effects. Dianette, a contraceptive pill, is not suitable for this patient who is trying to conceive. Antibiotics like oxytetracycline, tetracycline, lymecycline, and doxycycline can accumulate in growing bones and teeth, making them unsuitable for use during pregnancy. Erythromycin, on the other hand, is considered safe for use during pregnancy.

Acne vulgaris is a common skin condition that usually affects teenagers and is characterized by the obstruction of hair follicles with keratin plugs, resulting in comedones, inflammation, and pustules. The severity of acne can be classified as mild, moderate, or severe, depending on the number and type of lesions present. Treatment for acne typically involves a step-up approach, starting with single topical therapy and progressing to combination therapy or oral antibiotics if necessary. Tetracyclines are commonly used but should be avoided in certain populations, and a topical retinoid or benzoyl peroxide should always be co-prescribed to reduce the risk of antibiotic resistance. Combined oral contraceptives can also be used in women, and oral isotretinoin is reserved for severe cases under specialist supervision. Dietary modification has no role in the management of acne.

Topical diclofenac can be utilized to treat mild actinic keratoses in this individual.

Actinic keratoses, also known as solar keratoses, are skin lesions that develop due to prolonged exposure to the sun. These lesions are typically small, crusty, and scaly, and can appear in various colors such as pink, red, brown, or the same color as the skin. They are commonly found on sun-exposed areas like the temples of the head, and multiple lesions may be present.

To manage actinic keratoses, prevention of further risk is crucial, such as avoiding sun exposure and using sun cream. Treatment options include a 2 to 3 week course of fluorouracil cream, which may cause redness and inflammation. Topical hydrocortisone may be given to help settle the inflammation. Topical diclofenac is another option for mild AKs, with moderate efficacy and fewer side-effects. Topical imiquimod has shown good efficacy in trials. Cryotherapy and curettage and cautery are also available as treatment options.

Common Elbow Injuries in Children and Adults

Radial head subluxation is a frequent injury in children under the age of 6 years. The rounded end of the radial head is still made of cartilage and can easily slip out of the encircling annular ligament when the arm is pulled. There is usually no history of trauma, but there may be a history of axial traction by a pull on the hand or wrist. Tenderness at the head of the radius may be present. Imaging is only necessary when a fracture is suspected. Manipulation can be done in the GP surgery by immobilizing the elbow with one hand and with the other hand applying axial compression while supinating the forearm and flexing the elbow. Alternatively, it can be done while pronating the forearm. A click indicates success.

Supracondylar fracture of the humerus is most commonly seen in children and usually results from a fall on to an outstretched arm. The patient usually has elbow swelling and pain.

Lateral epicondylitis (tennis elbow) is a chronic condition that peaks between 40 and 50 years of age. It is thought to be an overload tendon injury.

Radial neck fracture occurs due to trauma such as a fall onto the outstretched arm. The median age is 9–10 years. There is pain, swelling, and tenderness over the lateral side of the elbow.

In cases of suspected non-accidental injury, the explanation should be consistent with the injury, and in the absence of other features, non-accidental injury is unlikely.

Understanding Otitis Externa: Myths and Facts

Otitis externa, commonly known as swimmer’s ear, is a condition that affects the skin of the external ear canal. Here are some common myths and facts about this condition:

Myth: Otitis externa is always bacterial in origin.
Fact: While bacterial pathogens are frequently involved, viral and fungal pathogens may also be seen, particularly after prolonged use of corticosteroid drops.

Myth: If adequately treated, otitis externa is unlikely to recur.
Fact: Otitis externa is commonly recurrent, especially in the presence of a predisposing factor, such as a chronic underlying skin disease, immunodeficiency or diabetes.

Myth: Systemic complications are common.
Fact: Severe infections may cause local lymphadenitis or cellulitis. Rarely, infection may invade the deeper adjacent structures and progress to necrotising (malignant) otitis externa, a condition that can cause serious morbidity and also mortality. This is mainly seen in immunocompromised individuals, particularly people with diabetes.

Myth: The use of aminoglycoside antibiotics is contraindicated.
Fact: In a patient who doesn’t have grommets or a perforated eardrum, aminoglycosides (eg gentamicin) or polymyxin drops are not contraindicated. When the eardrum is not intact, there is concern about ototoxicity. If necessary, they can be used in these circumstances, with caution, by specialists.

Debunking Myths About Otitis Externa

To avoid the need for additional barrier contraception, the woman should begin taking the pill immediately as she is currently menstruating and therefore not at risk of pregnancy. The combined contraceptive pill, except for Qlaira and Zoely, can be started within the first five days of a menstrual cycle without requiring further contraception. If started on day six or later, seven days of barrier contraception or abstinence is recommended. Waiting until day eight or the next menstrual period is unnecessary as the starting rules remain the same.

Pros and Cons of the Combined Oral Contraceptive Pill

The combined oral contraceptive pill is a highly effective method of birth control with a failure rate of less than one per 100 woman years. It is a convenient option that doesn’t interfere with sexual activity and its contraceptive effects are reversible upon stopping. Additionally, it can make periods regular, lighter, and less painful, and may reduce the risk of ovarian, endometrial, and colorectal cancer. It may also protect against pelvic inflammatory disease, ovarian cysts, benign breast disease, and acne vulgaris.

However, there are also some disadvantages to consider. One of the main drawbacks is that people may forget to take it, which can reduce its effectiveness. It also offers no protection against sexually transmitted infections, so additional precautions may be necessary. There is an increased risk of venous thromboembolic disease, breast and cervical cancer, stroke, and ischaemic heart disease, especially in smokers. Temporary side effects such as headache, nausea, and breast tenderness may also be experienced.

Despite some reports of weight gain, a Cochrane review did not find a causal relationship between the combined oral contraceptive pill and weight gain. Overall, the combined oral contraceptive pill can be a safe and effective option for birth control, but it is important to weigh the pros and cons and discuss any concerns with a healthcare provider.

The Impact of CYP Inducers on Medications: A Case Study

CYP inducers can have a significant impact on medications that are metabolized by cytochrome P450 enzymes. In the case of carbamazepine and ciclosporin, carbamazepine’s induction of the enzymes would increase the rate of metabolism of ciclosporin, potentially leading to decreased plasma levels and serious implications due to ciclosporin’s narrow therapeutic window. Paracetamol is also metabolized by CYP, and while it is not contraindicated with carbamazepine, the production of a hepatotoxic metabolite may be relevant in cases of overdose. Lithium, on the other hand, is excreted renally, so induction of P450 enzymes would not alter its excretion rate, but changes in renal function could still impact its plasma level. Penicillins have a wide therapeutic index, so the impact of CYP inducers or inhibitors is not significant. As for salicylate, there is currently no listed interaction with carbamazepine, making it unlikely to cause any issues in this patient.

• Sensitivity (Sens): The probability that the test is positive given that the disease is present. In this case, it is 80% or 0.80.
• Specificity (Spec): The probability that the test is negative given that the disease is not present. In this case, it is 85% or 0.85.
• Likelihood Ratio for a Negative Test Result (LR): The ratio of the probability of a negative test result in patients with the disease to the probability of a negative test result in patients without the disease. It is calculated as:

  LR−=(1−Sensitivity)/Specificity​

Calculation

Using the provided sensitivity and specificity:

• Sensitivity = 0.80
• Specificity = 0.85

Substitute these values into the formula for the negative likelihood ratio:

LR=(1−Sensitivity)/Specificity

LR=(1−0.80)/0.85​

LR=0.20/0.85

$$\text{LR}\approx 0.235$$

Hypertrophic obstructive cardiomyopathy is a more frequent cause of sudden death or unexpected collapse in young individuals compared to aortic stenosis.

Hypertrophic obstructive cardiomyopathy (HOCM) is a genetic disorder that affects muscle tissue and is inherited in an autosomal dominant manner. It is caused by mutations in genes that encode contractile proteins, with the most common defects involving the β-myosin heavy chain protein or myosin-binding protein C. HOCM is characterized by left ventricle hypertrophy, which leads to decreased compliance and cardiac output, resulting in predominantly diastolic dysfunction. Biopsy findings show myofibrillar hypertrophy with disorganized myocytes and fibrosis. HOCM is often asymptomatic, but exertional dyspnea, angina, syncope, and sudden death can occur. Jerky pulse, systolic murmurs, and double apex beat are also common features. HOCM is associated with Friedreich’s ataxia and Wolff-Parkinson White. ECG findings include left ventricular hypertrophy, nonspecific ST segment and T-wave abnormalities, and deep Q waves. Atrial fibrillation may occasionally be seen.

If a female under 18 discloses that she has undergone genital mutilation, the mandatory reporting duty applies. However, in this case, the individual is over 18, so the duty doesn’t apply, and there is no need to involve the police.

Instead, it is important to follow local safeguarding procedures and refer the individual to mental health services. It is recommended to refer her to mental health services rather than suggesting she self-refer or seek private counseling, as she may be hesitant to do so on her own. It is crucial to provide support and resources to help her cope with her feelings and experiences.

If the individual chooses to involve the police, it is her decision to make.

Understanding Female Genital Mutilation

Female genital mutilation (FGM) is a practice that involves the partial or total removal of the external female genitalia or other forms of injury to the female genital organs for non-medical reasons. This practice is classified into four types by the World Health Organization (WHO). Type 1 involves the partial or total removal of the clitoris and/or the prepuce, while Type 2 involves the partial or total removal of the clitoris and the labia minora, with or without excision of the labia majora. Type 3 involves the narrowing of the vaginal orifice with the creation of a covering seal by cutting and appositioning the labia minora and/or the labia majora, with or without excision of the clitoris. Type 4 includes all other harmful procedures to the female genitalia for non-medical purposes, such as pricking, piercing, incising, scraping, and cauterization. It is important to understand the different types of FGM to raise awareness and prevent this harmful practice.

If a patient experiences priapism, urgent assessment in a hospital is necessary. While priapism is a rare side effect of taking PDE-5 inhibitors, patients with blood disorders such as sickle cell disease, multiple myeloma, or leukemia are at an increased risk.

Priapism is considered a surgical emergency, and if it lasts for more than two hours, immediate referral to a hospital’s surgical team is required for treatment.

If the priapism has been present for less than two hours, some measures may help resolve it. These include attempting to pass urine, taking a warm bath or shower, drinking plenty of water, going for a gentle walk, doing exercises like squats or running on the spot, and taking painkillers like paracetamol if necessary.

Priapism is a condition where a man experiences a prolonged erection that lasts for more than 4 hours and is not related to sexual stimulation. There are two types of priapism: ischaemic and non-ischaemic. Ischaemic priapism is caused by reduced blood flow to the penis, while non-ischaemic priapism is caused by increased blood flow. Priapism can be caused by a variety of factors, including medication, trauma, and underlying medical conditions such as sickle cell disease. Symptoms include pain and a persistent erection. Diagnosis is made through clinical examination and tests such as blood gas analysis and ultrasonography. Treatment for ischaemic priapism involves aspiration of blood from the penis, injection of a saline flush, and vasoconstrictive agents. Non-ischaemic priapism is typically observed. It is important to seek medical attention promptly as untreated priapism can lead to permanent tissue damage and long-term erectile dysfunction.

Factors Affecting Response to Interferon Alpha in Hepatitis C Treatment

A high viral load, obesity, old age, cirrhosis, continued alcohol use, immune deficiency, poor adherence to treatment, and significant steatosis on liver biopsy are all factors that can affect the response rate to interferon alpha in hepatitis C treatment. Patients with genotype 1 infection and a high viral load are particularly at risk for a poor response to interferon alpha. On the other hand, patients with genotypes 2 or 3 infection and a short duration of disease have a better chance of responding well to treatment. The recommended duration of therapy also varies depending on the genotype. It is important to address these factors when considering treatment options for hepatitis C patients.

Giardiasis is suggested by the prolonged, non-bloody diarrhoea and the incubation period.

Understanding Giardiasis

Giardiasis is a disease caused by a type of protozoan called Giardia lamblia. It is transmitted through the faeco-oral route and can be contracted through various means such as foreign travel, drinking water from rivers or lakes, and even male-male sexual contact. While some people may not experience any symptoms, others may suffer from non-bloody diarrhea, bloating, abdominal pain, lethargy, flatulence, and weight loss. In some cases, malabsorption and lactose intolerance may also occur. To diagnose giardiasis, stool microscopy for trophozoite and cysts is usually done, although stool antigen detection assay and PCR assays are also being developed. Treatment for giardiasis involves the use of metronidazole.

Identifying Alzheimer’s Disease and Delirium

Alzheimer’s disease and delirium are two conditions that can affect cognitive function. Alzheimer’s disease is a slow and chronic condition that leads to gradual deterioration, while delirium is a sudden onset of confusion and disorientation.

Early signs of Alzheimer’s disease include a slow and chronic course with gradual deterioration. On the other hand, delirium is suggested by disorganised thought, poor attention, frequent fluctuations, and dysarthria.

To learn more about delirium, the British Geriatrics Society offers a great education resource on their Delirium hub. For information on managing and preventing cognitive symptoms of Alzheimer’s disease, check out the BMJ Clinical Review. Additionally, the BMJ Practice provides resources for suspected early dementia.

By understanding the differences between Alzheimer’s disease and delirium, individuals can seek appropriate medical attention and treatment.

Managing Urge Incontinence

Urge incontinence is a condition where urine leakage occurs involuntarily, often preceded by a sudden urge to urinate. According to NICE guidance on Urinary incontinence (CG171), women with urge incontinence or mixed incontinence should be offered bladder training as a first-line treatment for at least six weeks. This involves learning techniques to control the urge to urinate and gradually increasing the time between visits to the toilet. If bladder training is not effective, immediate release oxybutynin may be offered as an alternative treatment.

Acute kidney injury (AKI) is diagnosed through decreased glomerular filtration rate (GFR), increased serum creatinine or cystatin C, or oliguria. AKI is categorized into prerenal, renal, and postrenal. Prerenal AKI occurs when a normally functioning kidney responds to hypoperfusion by decreasing the GFR. Renal AKI refers to a condition where the pathology lies within the kidney itself. Postrenal failure is caused by an obstruction of the urinary tract. The most common cause of AKI in the renal category is acute tubular necrosis (ATN), which is usually due to prolonged ischaemia or nephrotoxins. Contrast-induced nephropathy (CIN) is defined as a significant increase in serum creatinine after a radiographic examination using a contrast agent. Preexisting renal insufficiency, preexisting diabetes, and reduced intravascular volume are associated with an increased risk of CIN. Adequate hydration is an important preventative measure. In most cases, renal function returns to normal within 7-14 days of contrast administration. Dialysis is required in less than 1% of patients, with a slightly higher incidence in patients with underlying renal impairment and in those undergoing primary coronary intervention for myocardial infarction. However, in patients with diabetes and pre-existing severe renal failure, the rate of dialysis can be as high as 12%.

DVLA guidance following a heart attack – refrain from driving for a period of 4 weeks.

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.

For the treatment of migraine, this patient should be prescribed an oral triptan along with either an NSAID or paracetamol for acute attacks. Additionally, prophylaxis should be considered as the patient experiences two or more attacks per month. Propranolol would be the most appropriate prophylaxis for this patient, as she is of childbearing age and topiramate may not be suitable. Pizotifen is no longer recommended for migraine prophylaxis due to its common side effects, while verapamil is used for prophylaxis of cluster headaches.

Managing Migraines: Guidelines and Treatment Options

Migraines can be debilitating and affect a significant portion of the population. To manage migraines, it is important to understand the different treatment options available. The National Institute for Health and Care Excellence (NICE) has provided guidelines for the management of migraines.

For acute treatment, a combination of an oral triptan and an NSAID or paracetamol is recommended as first-line therapy. For young people aged 12-17 years, a nasal triptan may be preferred. If these measures are not effective or not tolerated, a non-oral preparation of metoclopramide or prochlorperazine may be offered, along with a non-oral NSAID or triptan.

Prophylaxis should be considered if patients are experiencing two or more attacks per month. NICE recommends either topiramate or propranolol, depending on the patient’s preference, comorbidities, and risk of adverse events. Propranolol is preferred in women of childbearing age as topiramate may be teratogenic and reduce the effectiveness of hormonal contraceptives. Acupuncture and riboflavin may also be effective in reducing migraine frequency and intensity.

For women with predictable menstrual migraines, frovatriptan or zolmitriptan may be used as a type of mini-prophylaxis. Specialists may also consider candesartan or monoclonal antibodies directed against the calcitonin gene-related peptide (CGRP) receptor, such as erenumab. However, pizotifen is no longer recommended due to common adverse effects such as weight gain and drowsiness.

It is important to exercise caution with young patients as acute dystonic reactions may develop. By following these guidelines and considering the various treatment options available, migraines can be effectively managed and their impact on daily life reduced.

According to NICE guidelines, if a child under 6 months old has a UTI that responds well to antibiotics within 48 hours, an ultrasound scan should be done within 6 weeks. However, if the UTI is atypical or recurrent, additional tests such as ultrasound during the acute infection, DMSA 4-6 months after the acute infection, and MCUG are recommended.

An atypical UTI may present with symptoms such as being seriously ill, poor urine flow, an abdominal or bladder mass, elevated creatinine, failure to respond to antibiotics within 48 hours, or non-E. coli organisms. Recurrent UTI is defined as having two or more episodes of UTI with acute pyelonephritis/upper urinary tract infection, one episode of UTI with acute pyelonephritis/upper urinary tract infection plus one or more episodes of UTI with cystitis/lower urinary tract infection, or three or more episodes of UTI with cystitis/lower urinary tract infection.

Urinary tract infections (UTIs) in children require investigation to identify any underlying causes and potential kidney damage. Unlike in adults, the development of a UTI in childhood may indicate renal scarring. The National Institute for Health and Care Excellence (NICE) recommends imaging the urinary tract for infants under six months who present with their first UTI and respond to treatment, within six weeks. Children over six months who respond to treatment do not require imaging unless there are features suggestive of an atypical infection, such as being seriously ill, having poor urine flow, an abdominal or bladder mass, raised creatinine, septicaemia, failure to respond to antibiotics within 48 hours, or infection with non-E. coli organisms.

Further investigations may include a urine microscopy and culture, as only 50% of children with a UTI have pyuria, making microscopy or dipstick of the urine inadequate for diagnosis. A static radioisotope scan, such as DMSA, can identify renal scars and should be done 4-6 months after the initial infection. Micturating cystourethrography (MCUG) can identify vesicoureteric reflux and is only recommended for infants under six months who present with atypical or recurrent infections.

Many referrals for orthopaedic outpatient care from general practitioners are actually normal variants. The defining characteristics of normal variants are that they are always symmetrical, painless, and improve with age.

Genu varum, or bow legs, is a normal variant from birth until about 2 years of age. Referral should be considered if genu varum is asymmetrical or persists beyond 3 years of age. Severe cases may be indicative of vitamin D deficiency. Genu valgus, or knock knees, is a normal variant between 3-6 years of age. Again, referral should be considered if the valgus is severe or persists, and vitamin D deficiency may be a factor. Flat feet are a normal variant until age 3, and most cases resolve by age 8 as the foot arch develops. Arches should appear when the infant stands on their tip toes, and the foot should be flexible and painless. Painful rigid flat feet should always be referred and may suggest tarsal coalition.

In-toeing has three main causes: metatarsus adductus (a congenital foot deformity), internal tibial torsion (feet internally rotated), and femoral anteversion (feet and knees internally rotated). The vast majority of cases resolve by around 8 years of age.

Paediatric Orthopaedics: Common Conditions and Treatments

Developmental dysplasia of the hip is a condition that is usually diagnosed in infancy through screening tests. It may be bilateral, and when it is unilateral, there may be leg length inequality. As the disease progresses, the child may limp and experience early onset arthritis. This condition is more common in extended breech babies. Treatment options include splints and harnesses or traction, and in later years, osteotomy and hip realignment procedures may be needed. In cases of arthritis, a joint replacement may be necessary, but it is best to defer this if possible as it will likely require revision. Initially, there may be no obvious changes on plain films, and ultrasound gives the best resolution until three months of age. On plain films, Shenton’s line should form a smooth arc.

Perthes Disease is characterized by hip pain, which may be referred to the knee, and usually occurs between the ages of 5 and 12. Bilateral disease occurs in 20% of cases. Treatment involves removing pressure from the joint to allow for normal development and physiotherapy. If diagnosed and treated promptly, the condition is usually self-limiting. X-rays will show a flattened femoral head, and in untreated cases, the femoral head will eventually fragment.

Slipped upper femoral epiphysis is typically seen in obese male adolescents. Pain is often referred to the knee, and limitation to internal rotation is usually seen. Knee pain is usually present two months prior to hip slipping, and bilateral disease occurs in 20% of cases. Treatment involves bed rest and non-weight bearing to avoid avascular necrosis. If severe slippage or risk of it occurring is present, percutaneous pinning of the hip may be required. X-rays will show the femoral head displaced and falling inferolaterally, resembling a melting ice cream cone. The Southwick angle gives an indication of disease severity.

Missed Birth Control Pills

When it comes to missed birth control pills, most of the advice and evidence is based on studies of the 35 mcg oestrogen combined pill. However, it’s important to note that the risk of pregnancy with a missed 20 mcg pill may be higher than with a larger dose pill. Despite this, the Royal College of Obstetricians and Gynaecologists (RCOG) recommends that women take the missed pill and continue with the pack. Additional contraception is not required in this case.

If two or more pills are missed, it’s recommended to use barrier contraception for around seven days. It’s important to follow the instructions provided with your specific type of birth control pill and to speak with your healthcare provider if you have any concerns or questions.

Superior Vena Caval Obstruction (SVCO)

Superior Vena Caval Obstruction (SVCO) is a condition where there is a blockage of blood flow in the superior vena cava. This can be caused by external compression or thrombosis within the vein. The most common cause of SVCO is malignancy, with lung cancer and lymphoma being the most frequent culprits. Benign causes include intrathoracic goitre and granulomatous conditions such as sarcoidosis.

Typical features of SVCO include facial and upper body oedema, facial plethora, venous distention, and increased shortness of breath. Impaired venous return can cause dizziness and even syncopal attacks. Headache due to pressure effect is also seen.

Prompt recognition of SVCO on clinical grounds is crucial, and immediate referral for specialist assessment is necessary. If there is any stridor or laryngeal oedema, SVCO becomes a medical emergency.

Treatment for SVCO typically involves steroids and radiotherapy, with chemotherapy and stent insertion being indicated in some cases. Although dexamethasone may be given as an acute treatment, it is not the best answer for this patient, who needs to be referred immediately for inpatient treatment and monitoring.

In summary, SVCO is a serious condition that requires prompt recognition and referral for specialist assessment. Treatment options include steroids, radiotherapy, chemotherapy, and stent insertion, depending on the underlying cause.

Antibiotic Prophylaxis for Pertussis

When managing a suspected or confirmed case of pertussis, it is important to offer prophylactic antibiotics to reduce transmission if the case presents within 21 days of onset and a vulnerable contact is present in the household. All household contacts, regardless of age or immunisation status, should be offered antibiotics. Antibiotics may not alter the clinical course of the illness, but they can eliminate the organism from the respiratory tract, reducing person-to-person transmission. Vulnerable contacts include newborn infants, unimmunised or partially immunised infants or children up to 10 years, pregnant women, healthcare workers, immunocompromised individuals, and those with chronic illnesses. The maternal pertussis vaccine programme has been highly effective in preventing disease for infants less than 2 months of age. Therefore, the definition of vulnerable infants has been amended to include unimmunised infants born ≤32 weeks, unimmunised infants born >32 weeks whose mothers did not receive maternal pertussis vaccine after 16 weeks and at least 2 weeks before delivery, and infants aged 2 months or over who are unimmunised or partially immunised. It is important for GPs to understand and implement national guidelines for respiratory problems, including the management of pertussis.

When a patient with Addison’s disease experiences an intercurrent illness, it is recommended to increase their glucocorticoid dosage by two-fold. However, the dose of fludrocortisone should remain the same as usual, as it is not as crucial during times of illness. This is because individuals with Addison’s have limited or no natural steroid production, and the body typically responds to stress by increasing cortisol production.

Addison’s disease is a condition that requires patients to undergo glucocorticoid and mineralocorticoid replacement therapy. This treatment involves taking a combination of hydrocortisone and fludrocortisone. Hydrocortisone is usually given in 2 or 3 divided doses, with patients requiring 20-30 mg per day, mostly in the first half of the day. Fludrocortisone is also included in the treatment regimen. Patient education is crucial in managing Addison’s disease. Patients should be reminded not to miss glucocorticoid doses, and they may consider wearing MedicAlert bracelets and steroid cards. Additionally, patients should be provided with hydrocortisone for injection with needles and syringes to treat an adrenal crisis. It is also important to discuss how to adjust the glucocorticoid dose during an intercurrent illness.

During an intercurrent illness, the glucocorticoid dose should be doubled, while the fludrocortisone dose remains the same. The Addison’s Clinical Advisory Panel has produced guidelines that detail specific scenarios for managing intercurrent illness. These guidelines can be found on the CKS link for more information. Proper management of Addison’s disease is essential to ensure that patients receive the appropriate treatment and care they need to manage their condition effectively.

A pH level greater than 4.5 is linked to Trichomonas vaginalis and bacterial vaginosis.

Comparison of Bacterial Vaginosis and Trichomonas Vaginalis

Bacterial vaginosis and Trichomonas vaginalis are two common sexually transmitted infections that affect women. Bacterial vaginosis is caused by an overgrowth of bacteria in the vagina, while Trichomonas vaginalis is caused by a protozoan parasite. Both infections can cause vaginal discharge and vulvovaginitis, but Trichomonas vaginalis may also cause urethritis in men.

The vaginal discharge in bacterial vaginosis is typically thin and grayish-white, with a fishy odor. The pH of the vagina is usually higher than 4.5. In contrast, the discharge in Trichomonas vaginalis is offensive, yellow/green, and frothy. The cervix may also appear like a strawberry. The pH of the vagina is also higher than 4.5.

To diagnose bacterial vaginosis, a doctor may perform a pelvic exam and take a sample of the vaginal discharge for testing. The presence of clue cells, which are vaginal cells covered in bacteria, is a hallmark of bacterial vaginosis. On the other hand, Trichomonas vaginalis can be diagnosed by examining a wet mount under a microscope. The motile trophozoites of the parasite can be seen in the sample.

Both bacterial vaginosis and Trichomonas vaginalis can be treated with antibiotics. Metronidazole is the drug of choice for both infections. For bacterial vaginosis, a course of oral metronidazole for 5-7 days is recommended. For Trichomonas vaginalis, a one-off dose of 2g metronidazole may also be used. It is important to complete the full course of antibiotics to ensure that the infection is fully treated.

Beta-Blockers for Heart Failure Patients

Beta-blockers are recommended for all patients with heart failure due to left ventricular systolic dysfunction, regardless of age or comorbidities such as peripheral vascular disease, interstitial pulmonary disease, erectile dysfunction, diabetes, or chronic obstructive pulmonary disease without reversibility. However, asthma is a contraindication to beta-blocker use.

Bisoprolol, carvedilol, or nebivolol are the beta-blockers of choice for treating chronic heart failure due to left ventricular systolic dysfunction. These three beta-blockers have been proven effective in clinical trials and have prognostic benefits. Bisoprolol and carvedilol reduce mortality in all grades of stable heart failure, while nebivolol is licensed for stable mild to moderate heart failure in patients over the age of 70.

Even if a patient with heart failure is currently well and showing no signs of fluid overload, beta-blockers are still recommended due to their prognostic benefits.

Importance of Testing First Degree Relatives for Coeliac Disease

The prevalence of coeliac disease is high in individuals who have a first degree relative with the condition, with a rate of 1 in 10. This highlights the significance of offering testing to first degree relatives, even if they do not exhibit any symptoms. This recommendation is supported by NICE, as untreated coeliac disease can lead to an increased risk of various diseases, such as lymphoma and gut malignancy. Therefore, early detection and treatment of coeliac disease in first degree relatives can help prevent the development of these serious health complications. It is crucial to raise awareness about the importance of testing for coeliac disease in families with a history of the condition to ensure that individuals receive appropriate care and management.

Antipyretic Interventions for Children with Fever

Antipyretic drugs, such as paracetamol and ibuprofen, are recommended for children with fever if they appear distressed or unwell. However, these drugs should not be given solely to reduce body temperature or prevent febrile convulsions. Over-wrapping or underdressing a child with fever should also be avoided.

Either paracetamol or ibuprofen can be given, but ibuprofen should be avoided if the child is dehydrated. Both drugs are equally effective and well tolerated, but they should not be given at the same time. If one drug is not effective, the other drug may be added with caution over dosing intervals.

Aspirin should not be given to children under 16 years old due to safety concerns about the risk of developing Reye syndrome. Ibuprofen and/or paracetamol are appropriate for use.

NICE advises against examining an adnexal mass as it may lead to rupture.

Understanding Ectopic Pregnancy

Ectopic pregnancy occurs when a fertilized egg implants outside the uterus. This condition is a medical emergency that requires immediate attention. Women with ectopic pregnancy typically experience lower abdominal pain, which is often the first symptom. The pain is usually constant and may be felt on one side of the abdomen. Vaginal bleeding is another common symptom, which is usually less than a normal period and may be dark brown in color. Women with ectopic pregnancy may also experience dizziness, fainting, or syncope.

During a physical examination, doctors may find abdominal tenderness and cervical excitation, also known as cervical motion tenderness. However, they are advised not to examine for an adnexal mass due to the risk of rupturing the pregnancy. Instead, a pelvic examination to check for cervical excitation is recommended. In cases of pregnancy of unknown location, serum bHCG levels above 1,500 suggest an ectopic pregnancy.

In summary, ectopic pregnancy is a serious condition that requires prompt medical attention. Women who experience lower abdominal pain and vaginal bleeding should seek medical help immediately. Early diagnosis and treatment can prevent complications and improve outcomes.

Long-term steroid use often leads to psychiatric issues.

Corticosteroids are commonly prescribed medications that can be taken orally or intravenously, or applied topically. They mimic the effects of natural steroids in the body and can be used to replace or supplement them. However, the use of corticosteroids is limited by their numerous side effects, which are more common with prolonged and systemic use. These side effects can affect various systems in the body, including the endocrine, musculoskeletal, gastrointestinal, ophthalmic, and psychiatric systems. Some of the most common side effects include impaired glucose regulation, weight gain, osteoporosis, and increased susceptibility to infections. Patients on long-term corticosteroids should have their doses adjusted during intercurrent illness, and the medication should not be abruptly withdrawn to avoid an Addisonian crisis. Gradual withdrawal is recommended for patients who have received high doses or prolonged 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.
