Community-acquired pneumonia is a common clinical problem requiring admission to hospital, with a particularly high incidence in the elderly population and those with significant comorbidities. Diagnosis is made on the combination of a short history of respiratory symptoms and systemic ill-health with new examination and/or radiological features of consolidation. Multiple other infective and non-infective conditions can mimic community-acquired pneumonia, leading to misdiagnosis in 5-17% of cases. ⋯ Empirical antibiotic therapy for most patients admitted to hospital is combination of a ß-lactam and a macrolide. Short courses of antibiotics do not result in significantly different outcomes to longer courses unless the patient has developed complications such as a complex parapneumonic effusion. Implementation of a community-acquired pneumonia care bundle into clinical practice reduces mortality, and should be a high priority for all acute hospitals.

Compartment syndrome of the limb is a true orthopaedic emergency that warrants prompt evaluation and treatment. Acute compartment syndrome of the limb is not uncommon and has the potential to cause devastating morbidity and mortality. ⋯ Compartment syndrome can occur across all limbs, the buttocks and even the abdomen, but this article focuses solely on the diagnosis of acute compartment syndrome of the limb. Acute compartment syndrome can have a wide range of causes, with trauma representing approximately 70% of cases.

Nausea and vomiting are common symptoms in the hospital setting, with numerous causes. Common precipitants leading to or complicating inpatient hospital admissions include nausea and vomiting secondary to drugs, gastrointestinal disturbances, metabolic aberrancies, and vestibular pathologies. ⋯ There are numerous antiemetics available to physicians, ranging from muscarinic, dopaminergic and serotoninergic drugs, each acting on a different part of the nausea-vomiting cascade. This review describes the main pathophysiological processes involved in the development of symptomatic nausea and vomiting, and gives an overview of how common antiemetic drugs function to alleviate symptoms, alongside cautions and contraindications in their usage.

Direct oral anticoagulants have become the mainstay of the management of venous thromboembolism and atrial fibrillation, and long-term anticoagulation is indicated for those at high risk of further thrombotic events. This includes patients diagnosed with antiphospholipid syndrome, for whom the 'triple positive' laboratory combination of lupus anticoagulant, β2-glycoprotein-1 and anti-cardiolipin antibodies signify those at greatest risk. Data from meta-analysis and randomised control trials have raised the concern that direct oral anticoagulants may be less effective than vitamin K antagonists for the prevention of thrombosis in patients with thrombotic antiphospholipid syndrome, particularly those with the triple positive profile. This article reviews the diagnosis of thrombotic antiphospholipid syndrome, strategies for testing without interruption of anticoagulation, evidence concerning the safety of direct oral anticoagulants in this setting, and the implications for current investigation and management of unprovoked venous thromboembolism.
