Observational StudySimultaneous (two-surgeon) versus staged bilateral knee arthroplasty: an observational study of intraoperative and post-operative outcomes.
The advantages of simultaneous bilateral total knee arthroplasty (sim-BTKA) remain controversial. This study investigated the effects of two-surgeon sim-BTKA compared to separate admission staged BTKA regarding intraoperative and post-operative outcomes and health service costs. ⋯ Sim-BTKA appears to be a comparatively safe alternative to staged BTKA. Sim-BTKA may be superior to staged BTKA due to faster improvements in pain and function and lower healthcare costs. How these results generalize to other health services requires further investigation.

ReviewTargeted muscle reinnervation to improve electromyography signals for advanced myoelectric prosthetic limbs: a series of seven patients.
Upper limb amputation is a devastating injury. Patients may choose to use a passive prosthesis, a traditional body-powered prosthesis or a myoelectric prosthesis driven by electromyography (EMG) signals generated by underlying muscles. Targeted muscle reinnervation (TMR) aims to surgically create strong and reliable signals to permit the intuitive use of a myoelectric prosthesis with the greatest number of movements possible. We review the Alfred Hospital experience of using TMR to improve upper limb prosthesis control. ⋯ The use of TMR to improve and increase the number of EMG signals has been successful in generating more degrees of freedom for upper limb amputees with myoelectric prostheses.

Comparison of Raja Isteri Pengiran Anak Saleha Appendicitis and modified Alvarado scoring systems in the diagnosis of acute appendicitis.
The diagnosis of acute appendicitis (AA) is mainly dependent on clinical evaluation. There are several scoring systems developed for an accurate and early diagnosis of AA. Modified Alvarado score is one of the most common systems. The Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) scoring system was developed in 2010. The aim of this study is to evaluate and compare the accuracy of modified Alvarado and RIPASA scoring systems for the diagnosis of AA. ⋯ According to the current study, RIPASA scoring system was found to be superior to modified Alvarado in the prediction of cases with AA.
