METHODS: This was an observational manikin-based study. A total of 96 participants as well as two types of mechanical compression devices: Lucas-2 and AutoPulse, performed one minute of continuous chest compression on BT-CPEA programmed manikin while the ambulance travelled at different speeds, i.e., idle state, 30km/hr and 60km/hr. Seven outcome variables of chest compression were measured. Performance data of different groups of compressor were compared and analysed using repeated measures analysis of variance (ANOVA).

RESULTS: In manual chest compression, significant variation were noted among different speeds in term of average compression rate (p<0.001), average compression depth (p=0.007), fraction of adequate/insufficient compression depth and fraction of normal hands positioning with p=0.018, 0.022 and 0.034 respectively. Overall, AutoPulse and Lucas-2 were not affected by ambulance speed. Lucas- 2 showed more consistent average compression rate, higher fraction of adequate compression depth and reduced fraction of insufficient compression depth as compared to manual compression with p<0.001, 0.001 and 0.043 respectively.

MATERIALS AND METHODS: This was an observational case review study of all sexual assault cases from 2012-2017 at the OSCC of a suburban, tertiary hospital in Malaysia. A total of 304 cases were analysed.

RESULTS: The median age of the survivors was 15 years old. Majority were females (n=291, 95.7%), single (n=290, 95.4%), students (n=235, 77.3%), and from low socio-economic class (n=230, 75.7%). Rape constitutes the majority (n=246, 80.6%) with 153 cases (62.1%) were statutory rape. The most common perpetrator was the victim's boyfriend (n=107, 35.2%) while only 60 cases (19.7%) involved strangers. Delayed presentations were more likely among victims who previously knew their perpetrators (AOR 2.53, 95% CI: 1.37 to 4.68, p<0.01). The median duration for management at OSCC was 6.48 hours.
