Understanding Addison’s Disease

Addison’s disease is a rare condition caused by adrenal insufficiency, with the most common cause being autoimmune destruction of the adrenal glands. It affects a small percentage of the population, making it difficult to diagnose due to its vague symptoms. Patients may experience chronic fatigue, weight loss, and muscle weakness, among other symptoms. Differential diagnoses should be considered, including type 1 diabetes, eating disorders, and chronic fatigue syndrome.

Clinical examination and blood tests can provide clues to the presence of Addison’s disease. Postural hypotension, hyponatremia, and hyperkalemia are common features. A serum cortisol level done at 8-9 am can also be helpful in diagnosing the condition. Levels below 100 nanomol/L require hospital admission, while levels between 100 and 500 nanomol/L merit endocrinology referral for further investigation.

It is important to have a high degree of suspicion when considering a diagnosis of Addison’s disease, as early detection and treatment can prevent acute crises and improve patient outcomes.

Hospital Admission Necessary for Patient with Asthma and Pneumonia

There are several indicators that suggest hospital admission is necessary for this patient. Despite already taking preventative measures for his asthma with Beclomethasone diproprionate 100 mcg/Formetorol fumarate 6 mcg, his usage of salbutamol has increased and he has a productive cough with fevers, indicating a potential bacterial infection. Additionally, his oxygen levels are low, requiring oxygen therapy and monitoring of his oxygen saturations. He is also febrile with evidence of a focal infection and tachycardic. His CRB-65 score of 2, due to his blood pressure being <60 diastolic and his age being >65, further supports the need for hospitalization. Furthermore, his peak flow is less than 50%, indicating both pneumonia and an acute asthma attack.

While other options may be reasonable, such as adjusting his medication or providing home care, this patient requires intravenous antibiotics, oxygen therapy, and monitoring of his oxygen saturations and steroids, all of which can only be provided in a hospital setting.

Understanding the Symptoms of Acute Severe and Life Threatening Asthma

Asthma attacks can vary in their severity and duration. Tachycardia, or a rapid heart rate of over 110 beats per minute, is common during an attack. However, as the attack progresses, bradycardia, or a slow heart rate, may develop. Attacks can occur quickly, in less than an hour, or gradually over several days.

During an asthma attack, loud wheezing sounds usually indicate adequate air entry. However, as the attack worsens, the chest may become silent, and the patient may experience pulsus paradoxus, a condition where the pulse weakens during inhalation. Pulse oximetry readings are typically less than 90%.

Patients with acute severe and life-threatening asthma may struggle to complete sentences in one breath. However, a peak expiratory flow (PEF) of less than 33% of the predicted value is a sign of life-threatening asthma. It’s important to note that the inability to complete a full sentence in one breath alone doesn’t differentiate between acute severe and life-threatening asthma. Understanding these symptoms can help individuals with asthma seek appropriate medical attention and treatment.

NT-proBNP Guidelines for Heart Failure Diagnosis

NICE guidelines provide clear instructions for the interpretation of NT-proBNP levels in the diagnosis of heart failure. An NT-proBNP level above 2000ng/litre indicates a poor prognosis and requires urgent referral for specialist assessment and echocardiography within 2 weeks. For levels between 400 and 2000 ng/litre, referral should be made within 6 weeks. However, an NT-proBNP level less than 400 ng/litre makes a diagnosis of heart failure less likely. It is important to keep in mind that certain factors such as obesity, Afro-Caribbean family origin, and medication use can reduce the reading. Therefore, careful consideration of these factors is necessary when interpreting NT-proBNP levels. By following these guidelines, healthcare professionals can ensure timely and accurate diagnosis of heart failure.

Superior Vena Caval Obstruction (SVCO)

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

The typical features of SVCO include facial/upper body oedema, facial plethora, venous distention, and increased shortness of breath. Other symptoms may include dizziness, syncopal attacks, and headache due to pressure effect. Prompt recognition of SVCO on clinical grounds and immediate referral for specialist assessment is crucial. If there is any stridor or laryngeal oedema, SVCO is considered a medical emergency.

Management of SVCO involves treatment with steroids and radiotherapy. Chemotherapy and stent insertion may also be indicated. It is important to address the underlying cause of SVCO to prevent further complications.

This case highlights the significance of obtaining a thorough travel history when diagnosing illnesses. In this scenario, the patient presented with symptoms of fever, headache, weakness, vomiting, and diarrhoea. While influenza is a common cause of winter illnesses, meningococcal meningitis and trypanosomiasis did not fit the chronology, and cryptosporidium infection typically presents with watery diarrhoea within days of infection.

Upon further investigation, it was discovered that the patient had recently travelled to India, where malaria is prevalent. Falciparum malaria typically presents within three months of infection, but Vivax malaria can take up to a year to manifest. The symptoms of malaria include cyclical fever and chills, headache, weakness, vomiting, and diarrhoea, and patients may also present with splenomegaly.

Therefore, it is crucial for healthcare providers to obtain a detailed travel history when evaluating patients with symptoms of infectious diseases. This information can aid in the timely and accurate diagnosis and management of illnesses.

Two-Level DVT Wells Score

A Two-Level DVT Wells score is a tool used to determine the likelihood of a deep vein thrombosis (DVT) in a patient. The score is calculated based on several factors, including cancer, recent immobilization, major surgery, tenderness along the deep venous system, leg swelling, pitting edema, non-varicose collateral superficial veins, and past medical history of DVT.

A score of one point is given for each of these factors, except for past medical history of DVT, which automatically scores one point. Two points are subtracted if another diagnosis is more likely. If the score is two points or more, the probability of a DVT is likely, while a score of one point or less indicates an unlikely probability.

It is important to note that in this case, the swelling is not greater than 3 cm and the minimal pitting is equal on both sides, which may affect the overall score and probability of a DVT.

Hypertrophic obstructive cardiomyopathy (HOCM) is a condition caused by left ventricular outflow tract obstruction due to septal hypertrophy. It can be inherited or sporadic, and a family history of sudden death should be considered. Symptoms include chest pain, shortness of breath, palpitations, pre-syncope, and syncope. Clinical signs include a ‘jerky’ pulse, double apex impulse, and a prominent systolic thrill with a harsh ejection systolic murmur.

Brugada syndrome is a rare inherited cardiac condition that can cause sudden cardiac death. It is caused by a genetic mutation affecting the cardiac sodium channels and is inherited in an autosomal dominant pattern.

Long-QT syndrome can be inherited or acquired and predisposes to ventricular tachycardia and sudden death. Causes include various drugs, ischaemic heart disease, and metabolic abnormalities such as hypocalcaemia.

Pericarditis can present acutely with chest pain that worsens when lying flat and with inspiration. A pericardial rub may be audible, and causes include viruses, bacteria, fungi, and systemic diseases.

Constrictive pericarditis occurs when the pericardium becomes rigid and mainly leads to signs of right heart failure. Clinical signs include a diffuse apex beat, quiet heart sounds, and Kussmaul’s sign (JVP rises with inspiration paradoxically). It can occur after an episode of acute pericarditis.

Wolff-Parkinson-White syndrome is caused by an accessory pathway that conducts between the atrium and ventricle, facilitating abnormal conduction and often presenting with supraventricular tachycardia.

Two-Level DVT Wells Score for Assessing Probability of DVT

When assessing the probability of a deep vein thrombosis (DVT), a two-level DVT Wells score should be used. This score takes into account various factors and findings, such as cancer, recent immobilization, leg swelling, and tenderness. One point is given for each of these factors, and two points can be subtracted if another diagnosis is more likely.

If the score is two points or more, it is likely that the patient has a DVT and a proximal leg vein ultrasound scan should be performed within four hours. If the scan cannot be carried out within four hours, a parenteral anticoagulant should be given and the scan arranged within 24 hours.

If the score is one point or less, D-dimer testing should be performed. A positive result should be followed up with a proximal leg vein ultrasound scan within four hours, and a negative result should prompt consideration of an alternative diagnosis.

In the case of the patient described, she scores at least two points, making a DVT likely. Therefore, she should be referred for a proximal leg vein ultrasound scan to be performed within four hours.

Assessment and Severity of Acute Asthma

Questions about the assessment and severity of acute asthma are common in exams. To address this, the British Thoracic Society (BTS) has provided clear guidance on the assessment and management of acute asthma. It is important to familiarize oneself with this document.

Indicators of acute severe asthma include a peak expiratory flow rate of 33-50% of the patient’s best or predicted rate, a respiratory rate of 25 or greater, a heart rate of 110/min or greater, or the inability to complete sentences in one breath. It is important to note that there is no fixed numerical peak flow rate for all patients, as it depends on their usual best reading or predicted peak flow reading. If their actual peak flow is 33-50% of this figure, then it is a marker of an acute severe attack.

According to BTS guidance, pulsus paradoxus is not an adequate indicator of the severity of an acute asthma attack and should not be used. A pulse of 101/min would not be considered a marker of acute severe asthma because the threshold is 110/min or greater. However, a respiratory rate of 26/min is clearly above the threshold advised by BTS and would be a marker of an acute severe attack. If any of these features of an acute severe asthma attack persist after initial treatment, then the patient should be admitted.

The patient is likely suffering from acute renal colic due to a calcium-containing renal stone. IM diclofenac is the initial step in management, along with increased fluid intake and arranging for a urology opinion. Antispasmodics should not be offered. Assess response to initial treatment and admit if no response within 1 hour. Offer urgent imaging to confirm diagnosis and assess likelihood of spontaneous stone passage. Offer NSAIDs for pain relief, and consider opioids if necessary. Do not offer antispasmodics. Provide written information on renal and ureteric stones.

Acute Testicular Pain in Young Males: Torsion as the Primary Concern

In young males under 20 years of age who experience sudden testicular pain, it is crucial to consider torsion as the primary diagnosis. Failure to recognize this condition can lead to irreversible damage to the testes. Therefore, the most important action is to seek immediate medical attention and admission for acute urology opinion.

Prompt treatment within six hours of symptom onset can save most testes, while delaying treatment beyond 12 hours can result in the loss of the affected testicle. Therefore, it is essential to prioritize timely diagnosis and management of testicular torsion to prevent long-term complications and preserve fertility.

Severity of Ulcerative Colitis and the Truelove-Witts Criteria

Severe flare-ups of inflammatory bowel disease can lead to serious complications such as toxic megacolon, perforation, sepsis, and severe bleeding. Hospital admission and inpatient treatment are necessary in such cases. Severe ulcerative colitis is characterized by significant systemic upset and severe lower gastrointestinal symptoms. Blood investigations can provide further information on disease severity.

The Truelove-Witts criteria are a validated way of stratifying disease severity. According to these criteria, acute severe ulcerative colitis is defined as bowels open more than six times daily plus one or more of the following: haemoglobin less than 105 g/L, ESR greater than 30 mm/hr, pulse rate greater than 90 bpm, and temperature greater than 37.8°C.

If a patient presents with bloody diarrhea and systemic unwellness (fever and/or tachycardia), immediate hospital admission for in-patient assessment is necessary. Approximately half of severe ulcerative colitis attacks occur as a first attack in a patient without a previous diagnosis.

Moderate disease is classified as four to six stools a day (with or without blood) with minimal systemic disturbance. Mild disease is classified as less than four stools a day (with or without blood) with no systemic unwellness (no fever or tachycardia) and a normal ESR.

It is important to note that anti-diarrheal agents such as loperamide should be avoided as they have not been shown to reduce stool frequency in ulcerative colitis and have been associated with an increased risk of toxic megacolon. Studies from the 1950s show that untreated severe ulcerative colitis had a mortality rate of almost 25%, but with the use of corticosteroids and expert surgical input, this figure has been reduced to less than 1%.

Diagnosis Considerations for a Patient with Anorexia Nervosa

This patient is presenting with anorexia nervosa and self-induced vomiting, which can explain the low levels of sodium, potassium, and alkalosis. It is important to note that hypoalbuminemia may not be present until later stages of the disease.

When considering other potential diagnoses, Addison’s disease can cause hyponatremia and hyperkalemic acidosis, but the patient’s clinical presentation doesn’t align with this diagnosis. Additionally, there is no postural drop in blood pressure, which is not supportive of Addison’s disease.

Cushing’s disease can cause hypokalemic alkalosis, but again, the patient’s presentation doesn’t fit with this diagnosis.

Conn’s syndrome, which is associated with adrenal adenoma, can cause hypertension and hypokalemia. However, this diagnosis is not likely in this case.

In summary, the patient’s symptoms and laboratory results are consistent with a diagnosis of anorexia nervosa with self-induced vomiting.

Drug-induced Postural Hypotension

Drug-induced postural hypotension is a condition that can occur as a side effect of antihypertensive therapy, especially with the use of alpha-blockers. In this case, the patient’s recent introduction to doxazosin is a clue to the cause of their symptoms. Postural hypotension is characterized by a sudden drop in blood pressure when standing up, leading to dizziness, lightheadedness, and even fainting. It is important to monitor patients closely when starting new medications and adjust dosages as needed to prevent this potentially dangerous condition.

Management of Acute Renal Colic/Renal Calculi

This case involves a patient presenting with acute renal colic, which requires careful management to determine whether hospital admission is necessary. While a past history of renal calculi is not necessarily a reason for admission, the presence of a fever should prompt hospital referral to prevent the development of sepsis. Non-visible haematuria is a common finding in acute renal colic and doesn’t influence the decision to admit. However, age should be considered, particularly in men over 60 with left-sided pain, as they may have an aortic aneurysm mimicking renal colic. If the patient is dehydrated and unable to take oral fluids due to vomiting, admission and IV fluids are necessary. In this case, the patient is drinking satisfactorily. For more information on the management of acute renal colic, refer to the NICE Clinical Knowledge Summaries page.

Severity of Ulcerative Colitis and Hospital Admission

Severe flare-ups of inflammatory bowel disease require hospital admission and inpatient treatment due to potential complications such as toxic megacolon, perforation, sepsis, and severe bleeding. In the case of ulcerative colitis, disease severity can be determined using the Truelove-Witts criteria, which includes symptoms such as bowel movements more than six times a day, along with low hemoglobin levels, high ESR, elevated pulse rate, and fever.

A patient presenting with severe symptoms such as bloody diarrhea and systemic unwellness should be admitted immediately for in-patient assessment. The tachycardia should alert the clinician to systemic upset and prompt hospital admission to initiate treatment to guard against the development of complications. Studies have shown that untreated severe ulcerative colitis had a mortality rate of almost 25%, but with the use of corticosteroids and expert surgical input, this figure has been reduced to less than 1%.

It is important to note that approximately half of severe ulcerative colitis attacks occur as a first attack in a patient without a previous diagnosis. Moderate disease is classified as four to six stools a day (with or without blood) with minimal systemic disturbance, while mild disease is classified as less than four stools a day (with or without blood) with no systemic unwellness (no fever or tachycardia) and a normal ESR. Overall, the severity of ulcerative colitis should be carefully assessed to determine the appropriate level of care and treatment needed for the patient.

Prophylactic Antibiotics in Dog Bites

The use of prophylactic antibiotics in dog bites is a controversial topic. However, evidence supports their use in deep wounds, bites to the hands, and signs of infection. It is also important to consider immune compromise as an indication, along with involvement of deep structures such as joints or tendons, or in the presence of prosthetic joints.

For complicated animal bites, including those from cats or humans, co-amoxiclav is recommended as the first-line treatment. It is important to note that the treatment of animal bites, especially those on the hand, may require more than just antibiotics. Seeking the advice of a plastic surgeon for debridement or tendon repair may also be necessary. Proper treatment and care can help prevent further complications and promote healing.

NICE Guidelines for Suspected TIA

When suspecting a TIA has occurred within the last week, NICE advises administering aspirin 300 mg and seeking assessment within 24 hours by a stroke specialist physician. However, they no longer recommend using the ABCD2 scoring system as evidence shows it is poor at distinguishing between high and low risk of stroke after a TIA.

If the suspected TIA happened over one week ago, the patient can be referred for assessment within 7 days. Immediate admission should be considered for patients with a bleeding disorder or on an anticoagulant, those who have had more than one TIA (consider crescendo TIAs), severe carotid stenosis, suspected cardioembolic source, or lack reliable support at home to contact emergency services if further symptoms occur.

It is important to follow these guidelines to ensure proper assessment and treatment for patients with suspected TIA.

Assessment and Severity of Acute Asthma

Assessment and severity of acute asthma are common topics in exams. The British Thoracic Society provides clear guidance on the assessment and management of acute asthma, which should be familiar to healthcare professionals.

Indicators of acute severe asthma include a peak expiratory flow rate of 33-50% of the patient’s best or predicted rate, a respiratory rate of 25 or greater, a heart rate of 110/min or greater, or the inability to complete sentences in one breath. Oxygen therapy should aim to maintain SpO2 levels between 94-98%.

It is important to note that increasing symptoms is not a marker of an acute severe attack, but rather denotes a moderate asthma exacerbation. Additionally, there is no fixed numerical peak flow rate for all patients to determine the severity of their asthma. It depends on their personal best or predicted peak flow reading.

If a patient’s actual peak flow is 33-50% of their personal best or predicted rate, it is a marker of an acute severe attack. If any of the indicators of an acute severe asthma attack persist after initial treatment, admission is advised. A simple rule of thumb is that if the peak flow remains at <50% predicted or best after initial treatment, admission is recommended.

Acute Pancreatitis with Grey Turner’s Sign

The image depicts a case of acute pancreatitis, which is characterized by severe pain in the upper abdomen, vomiting, low blood pressure, and rapid heartbeat. The purple discoloration on the patient’s flank is known as Grey Turner’s sign, which is believed to be caused by bleeding in the retroperitoneal area associated with pancreatitis. This condition requires immediate hospitalization and medical attention.

Emergency Treatment in Primary Care

Potentially life-threatening situations are rare in primary care, but prompt action by a vigilant GP can save lives. Both NICE/CKS and the BNF are reference sources for the AKT exam, and they recommend admitting the person to the hospital as an emergency by calling 999. Treatment should not delay transfer to the hospital, and a single dose of parenteral benzylpenicillin should be administered as soon as possible, provided that it doesn’t delay urgent transfer to the hospital.

Emergency treatment is a crucial topic for the exam, and candidates have performed poorly in the past. It is essential to have benzylpenicillin, a suitable diluent, needles and syringes, and to be familiar with the correct doses for the age range. It is also crucial to ensure that the medicines in the emergency drug bag have not expired and to know who pays for them. More general GP admin and management issues appear to be a weak area for Registrars. If you are unsure about any of the questions posed, ask your trainer who pays for emergency drugs and whether the cost can be claimed back.

Guidelines for Identifying Acute Severe and Life-Threatening Asthma

Guidelines from the British Thoracic Society suggest that certain symptoms may indicate acute severe asthma, including an inability to complete sentences, a tachycardia above 110 bpm, a respiratory rate above 25/minute, and a PEFR of 33-50% of the predicted value. It is important to note that the threshold for pulse is higher than expected at 110 bpm.

In contrast, life-threatening asthma is characterized by more severe symptoms such as a silent chest, bradycardia, hypotension, and hypoxia. These symptoms require immediate medical attention and intervention to prevent further complications. By recognizing the signs of acute severe and life-threatening asthma, individuals can seek appropriate medical care and potentially prevent serious health consequences.

Paradoxical JVP Rise in Pericardial Effusion

Pericardial effusion, which may be infective as a result of previous tuberculosis, can cause a paradoxical rise in the jugular venous pressure (JVP) during inspiration. This is in contrast to the typical fall in JVP seen with inspiration. Treatment for pericardial effusion depends on the underlying cause, with an echocardiogram being the crucial initial investigation. If the effusion is particularly large and causing haemodynamic compromise, it may need to be tapped. Additionally, re-treatment with anti-tuberculous therapy is necessary. Proper diagnosis and management of pericardial effusion are essential to prevent further complications.

Choosing the Right Antibiotic for Epilepsy Patients

When it comes to choosing an antibiotic for patients with epilepsy, it’s important to consider the history of epilepsy. Rifampicin is the best option in this case, although it may reduce the effectiveness of other medications like phenytoin. Ofloxacin is an alternative, but it’s not recommended for patients with epilepsy. Ciprofloxacin is generally preferred for chemoprophylaxis, but it’s contraindicated for patients with epilepsy or conditions that increase the risk of seizures. However, in patients being treated with phenytoin, the benefits may outweigh the risks. It’s crucial to carefully consider the patient’s medical history and medication regimen before selecting an appropriate antibiotic.

Leptospirosis, also known as Weil’s disease, is a bacterial infection that can be transmitted to humans through contact with infected animals, including rodents, skunks, foxes, cattle, and dogs. Rat urine and faeces are common sources of transmission. Due to its varied symptoms, leptospirosis can be easily missed, making thorough history taking essential for diagnosis.

Symptoms of leptospirosis include fever, headache, myalgia, oliguria, jaundice, and enlargement of the liver and spleen. In some cases, patients may also experience haemorrhagic tendencies with purpura or petechiae. It is important to note that not all infected individuals will exhibit all of these symptoms.

Weil’s disease is a particular concern for those who participate in water sports, as the bacteria can survive in fresh and saltwater. In the UK, there are approximately 40 cases of leptospirosis reported each year, with the majority of cases occurring between June and October. Awareness of the potential for leptospirosis is crucial for early diagnosis and treatment.

Assessment and Severity of Acute Asthma

Questions about the assessment and severity of acute asthma are common in exams. To address this, the British Thoracic Society has provided clear guidance on the assessment and management of acute asthma. It is important to familiarize oneself with this document.

Indicators of acute severe asthma include a peak expiratory flow rate of 33-50% of best or predicted, a respiratory rate of 25 or greater, a heart rate of 110/min or greater, or the inability to complete sentences in one breath. The goal of oxygen therapy is to maintain SpO2 at 94-98%.

It is important to note that increasing symptoms is a vague description that only indicates a moderate asthma exacerbation and is not a marker of an acute severe attack. The only indicator of an acute severe asthma attack in this case is the patient’s inability to complete sentences in one breath.

If any of these features of an acute severe asthma attack persist after initial treatment, the patient should be admitted.

NICE’s Guidance on Head Injury Management

A base of open or depressed skull fracture or penetrating head injury requires immediate referral to the emergency ambulance (999) service. Signs of a skull fracture that warrant referral to the emergency ambulance service include clear fluid running from the ears or nose, black eye with no associated damage around the eyes, bleeding from one or both ears, and bruising behind one or both ears.

On the other hand, a positive Dix-Hallpike maneuver is simply consistent with benign positional paroxysmal vertigo. It is important to follow NICE’s guidance on head injury management to ensure prompt and appropriate care for patients with head injuries. Proper identification and referral of patients with skull fractures can prevent further complications and improve outcomes.

Acute Limb Ischaemia: Urgent Treatment Required

Patients experiencing acute limb ischaemia require immediate medical attention to potentially save their limb. This condition is characterized by several features, including pain, pallor, pulselessness, paraesthesia, paralysis, and perishingly cold skin. Pain is always present, and the ankle pulses are always absent. A useful rule of thumb is that if you can count the pulse, it’s there, but if not, it probably isn’t. Paraesthesia and paralysis are late, limb-threatening signs that require urgent treatment. Therefore, patients with acute limb ischaemia should be admitted as an emergency to receive potentially limb-saving treatment.

Criteria for Urgent Referral to Urology

There are specific criteria for urgent referral to urology that are based on the potential risk of underlying carcinoma. These criteria include macroscopic haematuria, microscopic haematuria in subjects over 60 who have either dysuria or a raised WBC count in blood, swellings of the body of the testis, palpable renal mass, solid renal mass found on imaging, an elevated age-specific prostate-specific antigen (PSA), and a clinically suspicious penile lesion.

It is important to familiarize oneself with the current indications for urgent referral. It is worth noting that patients over 60 years old may require more urgent attention, as indicated by the criteria for microscopic haematuria. By being aware of these criteria, healthcare professionals can ensure that patients receive timely and appropriate care.

CPR Guidelines for Adults

For adults, the recommended CPR technique involves a chest compression to ventilation ratio of 30:2. It is important to stay up-to-date with the latest guidelines provided by the Resuscitation Council (UK) as they offer useful and clearly presented algorithms. Familiarizing yourself with the latest information is crucial as the management of acute emergencies in the primary care setting is a popular subject for MRCGP AKT examination questions. You will be expected to be competent at carrying out the latest guidance, so make sure to read and understand the most recent guidelines.

Mycoplasma Infection: Diagnosis and Treatment

The symptoms of a young man with a chronic course, less severe chest signs than x-ray appearance, and erythema multiforme suggest mycoplasma infection. However, culture of mycoplasma is difficult, so diagnosis is mainly done through serology and PCR. The incubation period is around three weeks, and the infection is more common in the first two decades of life, especially in summer and autumn. Macrolides like erythromycin or clarithromycin are the primary treatment, with doxycycline as an alternative. With appropriate antibiotics, full recovery without long-term sequelae is expected. For more information on mycoplasma pneumonia, refer to the BMJ Best Practice and Clinical Features and Management articles.

Lyme Disease: A Tick-Borne Infection

Lyme disease is a bacterial infection caused by Borrelia burgdorferi, which is transmitted through tick bites. The disease was first described in Lyme, Connecticut, USA, and is also prevalent in areas such as the New Forest in Hampshire, UK. Not all patients remember being bitten, so a lack of tick bite history doesn’t rule out the disease.

Symptoms of Lyme disease include lethargy, arthralgia, and cognitive impairment, as well as lymphadenopathy, myocarditis, meningitis, cranial nerve palsies, and neuropathy. The typical rash, erythema chronicum migrans, presents as a papule that develops into a large spreading annular lesion with central fading. This rash can last up to three months, and multiple lesions can develop.

This patient has developed the typical rash and acute illness with a facial nerve palsy and evidence of myocarditis on the background of a trip to an area where infection is endemic. Serological diagnosis is needed to confirm infection, and treatment is with antibiotics active against the causative bacterium. Early treatment is essential, and treatment with antibiotics doesn’t preclude later testing. A common regime is several weeks’ treatment with doxycycline, provided treatment is started early.

Urgent Referral for Upper GI Endoscopy in Suspected Oesophageal Carcinoma

This patient’s medical history is indicative of an oesophageal carcinoma in the upper third, which is commonly associated with smoking and exposure to human papillomavirus. Although there are no signs of cervical lymphadenopathy, urgent referral to a gastroenterologist for upper GI endoscopy is necessary to rule out any underlying cancer.

Barium swallow is not recommended as upper GI endoscopy is a more effective option that allows for early tissue diagnosis. Helicobacter pylori testing is only useful in cases of potential duodenal ulcer disease, which is not the case here.

Stopping ibuprofen and trying omeprazole are not appropriate options as they may delay the diagnosis of any underlying oesophageal lesion. Therefore, urgent referral for upper GI endoscopy is the best course of action in suspected cases of oesophageal carcinoma.

Sick Day Rules for Patients with Addison’s Disease

Patients with Addison’s disease need to follow specific sick day rules to avoid catastrophic consequences. There are four scenarios that may be tested in the AKT exam: a patient with a temperature >37.5 degrees or treated with antibiotics, a patient who is vomiting, a patient with nausea, and a patient who has sustained major trauma and is at significant risk of shock.

According to the Addison’s Clinical Advisory Panel, patients must double their normal dose of hydrocortisone for a fever of more than 37.5 C or for infection/sepsis requiring antibiotics. For severe nausea, patients should take 20 mg hydrocortisone orally and sip rehydration/electrolyte fluids. On vomiting, patients should use the emergency injection (100 mg hydrocortisone) immediately and then call a doctor, saying Addison’s emergency. After a major injury, patients should take 20 mg hydrocortisone orally immediately to avoid shock.

It is essential to ensure that the anaesthetist and surgical team, dentist, or endoscopist are aware of the need for extra oral medication and that they have checked the ACAP surgical guidelines for the correct level of steroid cover, available at www.addisons.org.uk/publications. By following these sick day rules, patients with Addison’s disease can manage their condition effectively and avoid potential complications.

Management of Acute Asthma Exacerbation in Children

This article discusses the appropriate management of acute asthma exacerbation in children. In cases where the exacerbation is caused by an upper respiratory tract infection, symptom control and short-term measures are crucial. Adding long-acting beta agonists or leukotriene receptor antagonists is not recommended during acute exacerbation.

Hospital referral is not necessary if the child has no worrying features, no respiratory distress, and good oxygen saturations. However, advice on worsening should be given in case of relapse. Steroid treatment should be considered with any acute exacerbation, with oral prednisolone 1-2 mg/kg up to a maximum of 40 mg per day for three to five days.

Doubling the inhaled beclomethasone is not the correct answer. Instead, regular use of salbutamol during the current illness should be advised to prevent relapse and improve symptoms acutely. Delivery through a spacer device should also be encouraged. By following these guidelines, healthcare professionals can effectively manage acute asthma exacerbation in children.

Distal Intestinal Obstruction Syndrome in Cystic Fibrosis Patients

Distal intestinal obstruction syndrome (DIOS) is a common complication in 10-20% of cystic fibrosis patients, with incidence increasing as they age. It is caused by the loss of CFTR function in the intestine, leading to the accumulation of mucous and fecal material in the terminal ileum, caecum, and ascending colon. DIOS is usually diagnosed through a plain abdominal radiograph, which shows faecal loading in the right iliac fossa, dilatation of the ileum, and an empty distal colon. Ultrasound and CT scans can also be used to identify an obstruction mass and show dilated small bowel and proximal colon.

Treatment for mild and moderate episodes of DIOS involves hydration, dietetic review, and regular laxatives. N-acetylcysteine can be used in moderate episodes to loosen and soften the plugs. Severe cases may require gastrograffin or Klean-Prep, and surgical review should be obtained if there are signs of peritoneal irritation or complete bowel obstruction. In resistant cases, phosphate or gastrograffin enemas can be used, or colonscopy with installation of gastrograffin.

In summary, DIOS is a common complication in cystic fibrosis patients that can be diagnosed through radiographs, ultrasound, and CT scans. Treatment options vary depending on the severity of the episode, but hydration, dietetic review, and regular laxatives are often used for mild and moderate cases. Severe cases may require more aggressive treatment and surgical review.

Bronchiolitis: A Common Respiratory Infection in Infants

Bronchiolitis is a respiratory infection that commonly affects infants, with symptoms ranging from mild upper respiratory tract infection to severe lower respiratory tract symptoms. The infection is typically caused by respiratory syncytial virus (RSV), which leads to epidemics during the winter season. The severity of the infection is influenced by both baby and maternal factors.

Baby factors that increase the risk of severe bronchiolitis include chronic lung disease, congenital heart disease, immunodeficiency, and gastro-oesophageal reflux. On the other hand, maternal factors such as smoking and bottle feeding can also contribute to the severity of the infection. Breastfeeding, however, has been found to be partly protective against bronchiolitis.

In summary, bronchiolitis is a common respiratory infection in infants that can range from mild to severe. It is important for parents and caregivers to be aware of the risk factors that can increase the severity of the infection and take appropriate measures to prevent and manage it.

Diagnosis of Panic Attack

The ECG and pulse oximetry tests were normal, and the clinical context and examination findings all point to the diagnosis of a panic attack. It is appropriate to explain the diagnosis to the patient and provide reassurance.

Psychological symptoms of an anxiety state include irritability, intolerance of noise, poor concentration/memory, fearfulness, apprehensiveness, restlessness, and continuous worrying thoughts. On the other hand, physical symptoms of an anxiety state include dry mouth, difficulty in swallowing, chest pain, shakiness, diarrhoea, urinary frequency, paraesthesiae, and hot flashes. Physical signs of an anxiety state include tenseness, sweating, shaking, pallor, restlessness, and sighing.

It is important to recognize the symptoms and signs of a panic attack to provide appropriate care and support to the patient.

Understanding Organophosphate Insecticide Poisoning

Organophosphate insecticide poisoning is a condition that occurs when an individual is exposed to insecticides containing organophosphates. This type of poisoning inhibits acetylcholinesterase, leading to an increase in nicotinic and muscarinic cholinergic neurotransmission. In warfare, sarin gas is a highly toxic synthetic organophosphorus compound that has similar effects.

The symptoms of organophosphate poisoning can be predicted by the accumulation of acetylcholine, which can be remembered using the mnemonic SLUD. These symptoms include salivation, lacrimation, urination, defecation/diarrhea, cardiovascular issues such as hypotension and bradycardia, small pupils, and muscle fasciculation.

The management of organophosphate poisoning involves the use of atropine to counteract the effects of acetylcholine accumulation. The role of pralidoxime in treating this condition is still unclear, as meta-analyses to date have failed to show any clear benefit.
