PURPOSE: The aim of this study is to investigate the clinical performance and safety of Zimmer® natural nail cephalomedullary nail (ZNN CM nail) in the treatment of proximal femur fractures. MATERIALS AND METHODS: The following research was conducted as a prospective, non-comparative, single center outcome study. Upon providing written informed consent, enrolled patients' data were collected and analyzed. Postoperative follow-up visits were scheduled at 6 weeks, 3 months, 6 months, and 1 year. Follow-up evaluation included radiographic assessment, physical examination, and quality of life and adverse events reports. RESULTS: Thirty-nine patients were available for evaluation at one year postoperative. The patients reported the mean EuroQol-5 Dimension score increased after surgery: from 0.4 points at discharge (n=49) to 0.6 points at 1-year post-surgery (n=39). The mean Harris hip score also increased after surgery: from 56.3 points at discharge (n=49) to 72.1 points at 1 year (n=12). Bone union was seen in 64% (n=16) in 6 months and 95% (n=37) in 1 year. CONCLUSION: The results of this 1-year follow-up study affirmed the effectiveness and safety of the ZNN CM nail in the treatment of proximal femur fractures.

Rotator cuff tear is a common cause of shoulder pain and disability in adults. Due to the various nature of progression of rotator cuff tears and the complex biomechanics of the shoulder joint, repair and treatment of large-to-massive tears are challenging for many surgeons. Despite the recent popularity of reverse total shoulder arthroplasty as a treatment option for large-to-massive irreparable rotator cuff tears, biological and mechanical repair augmentation has also shown promise as a viable treatment option. The purpose of this study was to briefly summarize and review current studies on the assessment and arthroscopic treatment of large-to-massive rotator cuff tears, whether repairable or irreparable, to aid in developing a consensus on future treatment directions.

Zaire Ebola virus (EBOV) is a fatal human pathogen, with a high case fatality rate (CFR) averaging up to 78%. In March 2014, the World Health Organization (WHO) was made aware of a ZEBOV outbreak in rural Guinea, West Africa. Epidemiologic investigation linked the clinical and laboratory confirmed cases with the presumed first fatality of the outbreak in December 2013. EBOV from Guinea is a separate clade from other ZEBOV strains reported from the Democratic Republic of Congo (DRC) and Gabon. Since the outbreak in March, ZEBOV was also reported in Conakry, Guinea's capital and spread to other neighboring countries. In its largest outbreak, ZEBOV disease expanded through Guinea, Liberia, Sierra Leone, and Nigeria and to Spain, the USA, and the UK. The WHO declared the 2013-2015 West African Ebola epidemic a public health emergency of international concern considering its presumable capacity for further international spread. Early manifestations of EVD (Ebola virus disease) include a high fever, body aches, malaise, and fatigue. Severe diarrhea and other gastrointestinal manifestations such as vomiting were common, while bleeding was a more sporadic finding. The fatality rate was 43% and highest in patients aged > or = 45 years and the overall fitted mean incubation period was 10.3 days (95% CI 9.9~10.7). We present a review of the literature on the emergence of Ebola, and the epidemiologic, clinical, and laboratory records of patients in whom EVD was diagnosed in Sierra Leone, Guinea, Liberia, Mali, the USA, and Spain, its zoonotic origin, and the transmission of ZEBOV, as well as presenting original literature on the current Ebola outbreak.
