Medical use of cannabis in Switzerland: analysis of approved exceptional licences.
In recent years, the Swiss Federal Office of Public Health (FOPH) granted exceptional licenses for the medical use of cannabinoids, typically for 6 months with possible extensions. A systematic review of cannabinoids for medical use commissioned by the FOPH supports the use of cannabinoids for the treatment of chronic pain and spasticity. However, little is known about the patients treated with cannabinoids. We aimed to study medical uses of cannabinoids as part of the FOPH's programme of exceptional licenses. ⋯ Exceptional licences for medical use of cannabinoids have increased substantially in Switzerland, with the programme including patients with a wide range of conditions.

Meta AnalysisEarly versus late initiation of renal replacement therapy in patients with acute kidney injury: a meta-analysis of randomised clinical trials.
The optimal timing of renal replacement therapy (RRT) initiation in acute kidney injury (AKI) remains a matter of debate. A systematic review and meta-analysis of randomised controlled trials (RCTs) was conducted to better estimate the effects of early initiation of RRT compared with late initiation of RRT among patients with AKI and in patients at risk for AKI. ⋯ Early RRT in patients with AKI (or at risk for AKI) does not appear to provide a significant reduction in mortality rates compared with late RRT. The data did not suggest any apparent impact on renal recovery with early dialysis.

ReviewDizziness in the emergency department: an update on diagnosis.
This review aims to assist emergency physicians in finding the underlying aetiology when a patient presents with dizziness to the emergency department. After reading this review, the emergency physician will be able to consider the most relevant differential diagnoses and have an idea about dangerous aetiologies that require immediate action. The emergency physician will also know what diagnostic steps need to be taken at what time, such as the three-component HINTS Test (Head Impulse, Nystagmus, and Test-of-Skew), which helps with distinguishing central from peripheral causes of the acute vestibular syndrome. ⋯ Given that it would neither be economical nor practical to send all patients to specialists from the start, we present general guidelines for the diagnostic workup of patients presenting with dizziness to the emergency department. This review will focus on epidemiology, aetiologies, differential diagnoses and diagnostics. Treatment is described in a separate article.

Role of liver magnetic resonance imaging in hyperferritinaemia and the diagnosis of iron overload.
Hyperferritinaemia is a frequent clinical problem. Elevated serum ferritin levels can be detected in different genetic and acquired diseases and can occur with or without anaemia. It is therefore important to determine whether hyperferritinaemia is due to iron overload or due to a secondary cause. ⋯ Signal intensity ratio may be a good adjunct to R2 and R2* methods as it allows easy visual estimation of the liver iron concentration. In this review a group of Swiss haematologists and radiologists give an overview of different conditions leading to primary or secondary iron overload and on diagnostic methods to assess hyperferritinaemia with a focus on the role of liver MRI. They summarise the standard practice in Switzerland on the use of liver iron concentration MRI as well as disease-specific guideline recommendations.

Temporal trends of postpartum haemorrhage in Switzerland: a 22-year retrospective population-based cohort study.
Postpartum haemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality. Studies have reported an increase in incidence of postpartum haemorrhage in recent years. Our goal was to investigate changes in the incidence of postpartum haemorrhage (PPH) and its risk factors in Switzerland from 1993 to 2014. ⋯ Postpartum haemorrhage is a relatively common and potentially dangerous obstetric complication with increasing incidence over the last two decades in Switzerland. Its increase over time has been paralleled by an increase in uterine atony.
