RESUMO
SUMMARY: Cannabis legalisation continues to grow globally and its effects on the vascular system have been scrutinized.1 Cannabis has become recognised as a contributor to cardiovascular, cerebrovascular and peripheral vascular disease.2,3 This case report highlights the case of a young male patient presenting with atypical symptoms following cannabis use who developed gangrenous cholecystitis (GC) following vasospasm of his cystic artery. We believe that this is the first-ever case, shared with the anticipation of stimulating more research and prompting recognition of vascular events in this group of patients as our knowledge on the effects of cannabis continues to grow.

BACKGROUND: Magnetic resonance imaging (MRI) is widely regarded as the gold standard for assessment of the bile ducts in patients with bile duct injuries (BDIs). This case series aims to highlight the shortcomings of this imaging modality and demonstrate how it may overestimate the injury severity. METHODS: Three patients treated at Groote Schuur Hospital and the University of Cape Town in whom MRI/magnetic resonance cholangiopancreatography (MRCP) overestimated the severity of BDI were included in the study. Demographic characteristics, clinical presentation, blood results and imaging findings are presented. RESULTS: All patients had an MRI/MRCP done which assessed the BDIs as major complete cut-off of the proximal common hepatic duct with substance loss. Subsequent direct cholangiography showed minor injuries and all three patients were successfully managed with endoscopic stenting. CONCLUSION: Major BDIs are complex, and assessment of severity is intricate and may be overestimated. These patients are best managed in high-volume multidisciplinary team settings.

BACKGROUND: Despite the city of Johannesburg having one of the highest rates of crime in the world, no national databank for trauma exists. This study profiles the victims of penetrating trauma and identifies geographical areas in which it occurs, while describing the outcomes and patterns of injury. METHODS: A retrospective study including penetrating trauma patients triaged as Priority 1, presenting at the Chris Hani Baragwanath Academic Hospital's (CHBAH) trauma department over a six-year period (2011-2016). RESULTS: A total of 4 697 patients were included. The majority of victims were Black African males (92.1%) between the ages of 29-40 years, and stabbings were the most common mechanism of injury (71.8%), followed by gunshots. The commonest body area affected was the thorax, with a consequent haemothorax the most likely result. Weekends accounted for over 48% of all presentations - the last weekend of the month being the busiest. Region D was the area in Johannesburg with the highest trauma incidence (51.9%), with the oldest townships in Soweto found to be "hot spots". CONCLUSION: Penetrating trauma is inherently linked to alcohol abuse and interpersonal violence in South Africa,1 primarily affecting its young economic, working-class citizens. The data provided some insight into the burden, structure and challenges of our trauma system. These should be regarded as opportunities to implement change and improve our surveillance and prevention, beginning with a national trauma databank.

Infraumbilical-ring capillary abdominocentesis was compared with culdocentesis in 75 cases of suspected ruptured ectopic pregnancy, with patients serving as their own controls. There were 43 proven ectopic cases and the diagnosis was known in the remaining 32. The accuracy of results was equivalent: P greater than 0.15 for false positives and P greater than 0.63 for false negatives. For combined testing the positive predictive value reached 97%. The new method was easier to perform and should be preferred.
