Head injuries related to bicycle collisions and helmet use - an observational study.

Objectives: In Denmark, the use of bicycles is widespread, and head injuries are often seen in cyclists involved in collisions. Despite the well-known effects of using a helmet to reduce head injuries, using helmets is not mandatory in Denmark. The primary objective of this study was to provide data regarding injury outcomes and helmet usage.

Vertebro-Vertebral Fistula Occlusion Using a Woven EndoBridgeTM-Device.

Vertebro-vertebral fistulas (VVFs) are vascular lesions that may develop after trauma or spontaneously in association with connective tissue disorders. We present a rare case of a post-traumatic VVF in a young patient presenting with a painless swelling and a bruit in her left upper neck. Digital subtraction angiography showed an arteriovenous fistula between the left vertebral artery (VA) and the vertebral venous plexus with significant steal phenomenon.

Mortality among patients treated for aneurysmal subarachnoid hemorrhage in Eastern Denmark 2017-2019.

Objective: The aim of the study was to investigate (1) the 30-day, 3-month, and 12-month cumulative mortalities for patients who underwent aneurysm occlusion, and (2) the causes of death, and (3) the potential risk factors for death.

Methods: All patients who underwent surgical clipping or endovascular treatment of a ruptured aneurysm at Copenhagen University Hospital, during the period of January 1, 2017-December 31, 2019, were included and followed up for 12 months. Data regarding vital status, causes of death, comorbidities, treatment, and clinical presentations on admission was collected.

Patient costs and patient flow after implementation of S100B in Scandinavian head trauma guidelines.

Introduction: The serum biomarker S100B has been implemented in the Scandinavian Neurotrauma Committee (SNC) 2013 Head Injury Guidelines for patients classified with mild head injury (MHI). Patients with a serum S100B level less-than 0.10 μg/l sampled within six hours after trauma can be discharged without further observation or investigation.

Neurosurgical Admission Later Than 4 h After the Emergency Call Does Not Result in Worse Long-Term Outcome in Subarachnoid Haemorrhage.

Few studies have investigated the importance of the time interval between contact to the emergency medical service and neurosurgical admission in patients with spontaneous subarachnoid haemorrhage. We hypothesised that longer time to treatment would be associated with an increased risk of death or early retirement. This was a retrospective observational study with 4 years follow-up.
