The Guidelines in Emergency Medicine Network (GEMNet) has been created to promote best medical practice in a range of conditions presenting to emergency departments (EDs) in the UK. This guideline presents a summary of the best available evidence to guide the use of thromboprophylaxis in adult ambulatory outpatients who present to the ED following acute limb trauma and require temporary immobilisation. The document has been developed following discussion among emergency physicians and collegiate fellows to decide which topics would benefit from the development of clinical guidelines. The document is intended as a guideline for use in the ED by emergency physicians and is based on the review of the best existing evidence for treatments used in this setting. The document is summarised as a Clinical Decision Support Guideline that has been presented as an easy to follow algorithm. The intention is for each guideline to be updated and reviewed as further evidence becomes available. The formal revision date has been set at 5 years from publication, though the guideline is subject to continuous informal review.

The authors present the rare case of complete image-defined resolution of a hypothalamic hamartoma (HH) following Gamma Knife surgery (GKS). A 9-month-old girl presented with an episode of generalized tonic-clonic seizures. Magnetic resonance imaging revealed a left-sided HH, which remained radiologically stable. By 3 years of age the patient had a development delay of 12 months, and experienced 8 gelastic seizures per day while on 2 antiepileptic medications. Thirty-one months after presentation, the patient underwent elective GKS to treat the HH. She has since been seizure free for 22 months, while receiving 3 antiepileptic medications. Twelve months after radiosurgery, MRI revealed complete radiological resolution of the lesion. The authors discuss alternative management options for HH, including microsurgical resection, endoscopic disconnection, stereotactic radiofrequency thermocoagulation, and interstitial radiosurgery. Gamma Knife surgery is a minimally invasive procedure associated with a lower morbidity rate than that of published surgical results. The present case demonstrates the potential for complete image-defined resolution of an HH post-GKS, without long-term neurological sequelae, emphasizing the safety and efficacy of this therapeutic option for the control of epileptic seizures produced by small-volume, surgically inaccessible HHs.

Simultaneous bilateral spontaneous pneumothoraces (SBSP) are uncommon. This report presents the case of a previously well 19-year-old man with a diagnosis of SBSP and symptoms suggestive of occupational asthma. Despite bilateral bullectomy and pleurodesis using a video-assisted thoracoscopic surgical technique, the pneumothorax reoccurred unilaterally and open surgery was performed. This case illustrates a rare condition of bilateral pneumothoraces presenting as a first presentation of occupational asthma and the issues surrounding its management.
