| Main indications for chest drain in pleural infections | Patients with frankly purulent or turbid/cloudy pleural fluid on sampling should receive prompt pleural space chest tube drainage. The presence of organisms identified by Gram stain and/or culture from a non-purulent pleural fluid sample indicates that pleural infection is established and should lead to prompt chest tube drainage. Pleural fluid pH < 7.2 in patients with suspected pleural infection indicates a need for chest tube drainage. |
| What to do about a pneumothorax | Primary pneumothorax Recommendations include: if the rim of air is < 2cm and the patient is not short of breath then discharge should be considered otherwise aspiration should be attempted if this fails (defined as > 2 cm or still short of breath) then a chest drain should be inserted patients should be advised to avoid smoking to reduce the risk of further episodes - the lifetime risk of developing a pneumothorax in healthy smoking men is around 10% compared with around 0.1% in non-smoking men Secondary pneumothorax Recommendations include: if the patient is > 50 years old and the rim of air is > 2cm and/or the patient is short of breath then a chest drain should be inserted. otherwise aspiration should be attempted if the rim of air is between 1-2cm. If aspiration fails (i.e. pneumothorax is still greater then 1cm) a chest drain should be inserted. All patients should be admitted for at least 24 hours if the pneumothorax is less the 1cm then the BTS guidelines suggest giving oxygen and admitting for 24 hours avoid diving |
| When to consider referral for familial hypercholesterolaemia | a total cholesterol concentration more than 7.5 mmol/litre and a family history of premature coronary heart disease.

| Cholesterol goal in those started in statin | Measure total cholesterol, HDL cholesterol and non‑HDL cholesterol in all people who have been started on high‑intensity statin treatment at 3 months of treatment and aim for a greater than 40% reduction in non‑HDL cholesterol. If a greater than 40% reduction in non‑HDL cholesterol is not achieved: discuss adherence and timing of dose optimise adherence to diet and lifestyle measures consider increasing the dose if started on less than atorvastatin 80 mg and the person is judged to be at higher risk because of comorbidities, risk score or using clinical judgement Acceptable conservative LDL level ?4mmol/l |
| deep vs superficial venous ulcers | Deep venous insufficiency is related to previous DVT and superficial venous insufficiency is associated with varicose veins |
| When to start an inhaled corticosteroid | Inhaled steroids should be considered for patients with any of the following asthma-related features: exacerbations of asthma in the last two years using inhaled β2 agonists three times a week or more symptomatic three times a week or more waking one night a week |
| when to use an aldosterone antagonist in heart failure | patients who have had an acute MI and who have symptoms and/or signs of heart failure and left ventricular systolic dysfunction, treatment with an aldosterone antagonist licensed for post-MI treatment (e.g. eplerenone) should be initiated within 3-14 days of the MI, preferably after ACE inhibitor therapy |

| simple step up management for acne | single topical therapy (topical retinoids, benzyl peroxide) topical combination therapy (topical antibiotic, benzoyl peroxide, topical retinoid) oral antibiotics: e.g. Oxytetracycline, doxycycline. Improvement may not be seen for 3-4 months. Minocycline is now considered less appropriate due to the possibility of irreversible pigmentation. Gram negative folliculitis may occur as a complication of long-term antibiotic use - high-dose oral trimethoprim is effective if this occurs oral isotretinoin: only under specialist supervision |
