Combining energy drinks (such as 'Red Bull(®)') with alcohol is becoming increasingly popular, particularly among young people. However, as yet, limited research has been conducted examining the harms associated with this form of drinking. ⋯ Combining alcohol with energy drinks can mask the signs of alcohol intoxication, resulting in greater levels of alcohol intake, dehydration, more severe and prolonged hangovers, and alcohol poisoning. It may also increase engagement in risky behaviours (such as drink driving) as well as alcohol related violence. General practitioners should be aware of the harms associated with this pattern of drinking, and provide screening and relevant harm reduction advice.

Rheumatoid arthritis is a chronic disease that can cause irreversible joint damage and significant disability. With a prevalence of 1%, it has a considerable cost to the community. Diagnosis is based on a combination of clinical and laboratory features. Patients typically present with a symmetrical polyarthritis of the small joints of the hands and feet accompanied by early morning stiffness and, occasionally, constitutional symptoms. ⋯ It is increasingly recognised that there is a 'window of opportunity' within which disease modifying antirheumatic drug therapy should be commenced to arrest progressive disease and joint destruction. Methotrexate is usually the first line agent in the management of rheumatoid arthritis but simple analgesia and nonsteroidal anti-inflammatory drugs are also important for symptom control.

Warfarin is a commonly used medication for the prevention and treatment of venous thromboembolism. It can be challenging for both the patient and the prescriber to manage at times. ⋯ The common indications for warfarinisation are atrial fibrillation, venous thromboembolism and prosthetic heart valves. Contraindications include absolute and relative contraindications, and an individualised risk-benefit analyses is required for each patient. There are many interactions with warfarin, including pharmacokinetic and pharmacodynamic. Pharmacokinetic interactions can be monitored by using International Normalised Ratio levels. Pharmacodynamic interactions require knowledge by the prescriber to predict any interactions with warfarin, and International Normalised Ratio monitoring assists.

Pulmonary embolism remains a common and potentially preventable cause of death. ⋯ Well recognised risk factors include recent hospitalisation, other causes of immobilisation, cancer, and oestrogen exposure. Diagnostic algorithms for pulmonary embolism that incorporate assessment of pretest probability and D-dimer testing have been developed to limit the need for diagnostic imaging. Anticoagulation should be administered promptly to all patients with pulmonary embolism with low molecular weight heparin being the initial anticoagulant of choice, although thrombolysis is indicated for patients presenting with haemodynamic compromise. Following initial anticoagulation warfarin therapy should be continued for a minimum of 3 months. Long term anticoagulation with warfarin should be considered in patients with unprovoked pulmonary embolism, due to an increased risk of recurrence after ceasing anticoagulation. The availability of new anticoagulants is likely to significantly impact on the treatment of patients with pulmonary embolism, although the exact role of these drugs is still to be defined.

Traumatic head injury is a common occurrence in the paediatric population, with the majority of patients sustaining only mild head injury. ⋯ A careful history including time of injury, the mechanism of injury, and any loss of consciousness or seizure activity; a thorough examination including a Glascow Coma Scale (GCS) score; and observation should be appropriate for most patients. Only a small number of injuries require further examination/imaging with computerised tomography. Indicators for transfer to hospital include GCS equal to or less than 12, focal neurological deficit, clinical evidence of skull fracture, loss of consciousness for more than 30 seconds, ataxia, amnesia, abnormal drowsiness, persistent headache, seizure following initial normal behaviour or recurrent vomiting. Postconcussive symptoms frequently occur after minor head injuries and parents and other family members should be aware of what symptoms to expect, and possible duration. Regular follow up until all symptoms have resolved is mandatory, with clear guidelines for stepwise resumption of physical activity.
