Taser was introduced into UK policing in 2003 to bridge the operational gap between use of incapacitant sprays and firearms. Use of force reporting in the UK indicates that Taser is relatively safe provided that it is used lawfully. ⋯ The TASER 7 uses a novel probe that has implications for the medical community. A review of Taser medical effects and probe removal for TASER 7 are presented.

Meta Analysis
Diagnostic accuracy of point-of-care ultrasound for paediatric testicular torsion: a systematic review and meta-analysis.
Previous studies have examined the utility of ultrasonography performed by radiologists for diagnosing paediatric testicular torsion. While point-of-care ultrasound (POCUS) is used in paediatric emergency medicine, its diagnostic accuracy is still unknown. ⋯ The present systematic review and meta-analysis showed that POCUS had high sensitivity and specificity for identifying testicular torsion in paediatric patients although the risk of bias was high in the studies analysed.

The current guidelines of the American Heart Association (AHA) and European Society of Cardiology (ESC) recommend that when right ventricular myocardial infarction (RVMI) is present patients are not administered nitrates, due to the risk that decreasing preload in the setting of already compromised right ventricular ejection fraction may reduce cardiac output and precipitate hypotension. The cohort study (n=40) underlying this recommendation was recently challenged by new studies suitable for meta-analysis (cumulatively, n=1050), suggesting that this topic merits systematic review. ⋯ CRD42020172839.
