Rural emergency departments (EDs) are an important gateway to care for the 20% of Canadians who reside in rural areas. Less than 15% of Canadian rural EDs have access to a computed tomography (CT) scanner. We hypothesized that a significant proportion of inter-facility transfers from rural hospitals without CT scanners are for CT imaging. Our objective was to assess inter-facility transfers for CT imaging in a rural ED without a CT scanner. ⋯ We selected a rural ED that offers 24/7 medical care with admission beds but no CT scanner. Descriptive statistics were collected from 2010 to 2015 on total ED visits and inter-facility transfers. Data was accessible through hospital and government databases. Between 2010 and 2014, there were respectively 13,531, 13,524, 13,827, 12,883, and 12,942 ED visits, with an average of 444 inter-facility transfers. An average of 33% (148/444) of inter-facility transfers were to a rural referral centre with a CT scan, with 84% being for CT scan. Inter-facility transfers incur costs and potential delays in patient diagnosis and management, yet current databases could not capture transfer times. Acquiring a CT scan may represent a reasonable opportunity for the selected rural hospital considering the number of required transfers.

Comparative Study
In vitro biomechanical testing of the 3.5 mm LCP in torsion: a comparison of unicortical locking to bicortical nonlocking screws placed nearest the fracture gap.
This biomechanical study compared the torsional strength and stiffness of a locking compression plate with all locking versus nonlocking screws and examined the effect of placing a locking unicortical or nonlocking bicortical screw nearest the fracture gap in a synthetic bone model. ⋯ Synthetic bone models simulating a diaphyseal fracture without anatomic reduction were tested using four screw configurations: all bicortical locking (ABL), all bicortical nonlocking (ABN), a hybrid construct with a bicortical nonlocking screw nearest the fracture gap (BN), and a unicortical locking screw placed nearest the fracture gap (UL). Torsional stiffness, rotation and torque at failure were compared via ANOVA and post hoc pairwise comparisons (p < 0.05). ABN and BN had the highest stiffness (p < 0.01) with ABL greater than UL (p < 0.01). Rotation at failure was greatest for ABL (p < 0.01) with UL greater than ABN (p < 0.05). Unicortical locking screws nearest the fracture gap decreased stiffness, without significantly affecting torque or rotation at failure. Construct stiffness was found to exist in a very narrow range of 0.9-1.2 N m/deg with standard deviations of 0.1 N m/deg in all cases. The results of this study support the use of nonlocking screws in a hybrid construct to increase torsional stiffness.

Cerebral palsy is a major cause of disability and most survivors are left with residual disability and are dependent on parents/caregivers for essential care. This study aimed to determine the experiences of parents/caregivers of cerebral palsy children receiving out-patient physiotherapy. A concurrent mixed methods was used to collect data in the present study. The modified caregiver strain index (MCSI-13) was used to detect Disturbed sleep, Inconvenient/Tiresome, Physical strain, Confining, Family changes, Changes in personal plan, Other demands, Emotional adjustments, Upsetting behavior, Patient has changed, Work adjustments, Financial Strain and Feeling Overwhelmed (strain morbidity) in 25 parents/caregivers of CP children. A purposive sample of 25 parents/caregivers was selected for both the quantitative part and qualitative part of the study. The study was conducted at Community Based Intervention Association Out-patients at the University Teaching Hospital in Lusaka, Zambia. The MCSI was used to collect quantitative data and in-depth interviews provided the qualitative data. ⋯ This study point out to some evidence that the burden inflicted on those caring for children with cerebral palsy should be addressed if the quality of care for those with cerebral palsy is to be improved.

Case Reports
Occurrence of spontaneous bilateral tubal pregnancy in a low-income setting in rural Cameroon: a case report.
Ectopic pregnancy is a life-threatening emergency warranting immediate recognition and prompt intervention. Bilateral tubal pregnancy is the rarest form of ectopic pregnancy with very limited data on its occurrence reported in sub-Saharan Africa. ⋯ Ectopic pregnancy is one of the major causes of maternal mortality in sub-Saharan Africa. Thus, clinicians should maintain a high index of suspicion, even in the absence of hallmark features and thorough clinical examination undertaken especially in resource-limited settings. Examination of both tubes at laparotomy for ectopic pregnancy should be routine and mandatory.
