Background. Initially developed to excite peripheral nerves, magnetic stimulation was quickly recognized as a valuable tool to noninvasively activate the cerebral cortex. The subsequent discovery that repetitive transcranial magnetic stimulation (rTMS) could have long-lasting effects on cortical excitability spawned a broad interest in the use of this technique as a new therapeutic method in a variety of neuropsychiatric disorders. Although the current outcomes from initial trials include some conflicting results, initial evidence supports that rTMS might have a therapeutic value in different neurologic conditions. ⋯ Lastly, only two randomized, sham-controlled studies have been performed for epilepsy; although evidence indicates rTMS may reduce seizure frequency in patients with neocortical foci, more research is needed to confirm these initial findings. Conclusions. There is mounting evidence for the efficacy of rTMS in the short-term treatment of certain neurologic conditions. More long-term research is needed in order to properly evaluate the effects of this method in a clinical setting.

Background. Patients with unstable angina pectoris may become refractory to conventional therapies. Electrical neurostimulation with transcutaneous electrical stimulation and/or spinal cord stimulation has been shown to be effective for patients with refractory unstable angina pectoris in hospital settings. Our aim was to investigate the effects of electrical neurostimulation on outcomes of unstable angina after hospital discharge, in terms of hospital re-admission rates and long-term survival analysis. ⋯ The combined mortality and (re)infarction rate after one-year follow-up was 14%. Conclusion. The results of this observational study show long-term beneficial effects of electrical neurostimulation in a population of patients with unstable refractory angina. Therefore, electrical neurostimulation should be considered as a beneficial treatment for patients with unstable angina pectoris, refractory to conventional therapies.

Primary Hemiarthroplasty for Proximal Humeral Fractures in the Elderly: Long-Term Functional Outcome and Social Implications.
Primary shoulder hemiarthroplasty is an established treatment modality for complex fractures of the proximal humerus. Long-term functional outcome is often disappointing. However, little is known about social implications particularly in the elderly. ⋯ Most patients managed their daily life independently despite poor shoulder function.

Functional Outcome after Operative Treatment of Displaced Fractures of the Acetabulum: A 12-month to 5-year Follow-up Investigation.
To review our experience with 82 surgically treated displaced acetabular fractures over a 4-year period. ⋯ Operative treatment is an effective method for the management of displaced acetabular fractures. Clinical and roentgenographic results correlate closely with an anatomic reduction. Low complication rate can be expected if adequate preoperative assessment and planning is performed. Strategies to minimize the risk of thromboembolism and heterotopic ossification on the basis of mechanical pneumatic compression and antiinflammatory nonsteroidal drugs, respectively, are reliable techniques for these injuries.

Secondary hyperparathyroidism (sHPT) is common in patients with chronic renal failure. Despite the initiation of new therapeutic agents, several patients will require parathyroidectomy (PTX). Total PTX with autotransplantation of parathyroid tissue (TPTX+AT) and subtotal parathyroidectomy (SPTX) are currently considered as standard surgical procedures in the treatment of sHPT. Recurrencerates after TPTX+AT or SPTX are between 10% and 12% (median follow up: 36 months). Recent retrospective studies demonstrated a lower rate of recurrent sHPT of 0-4% after PTX without autotransplantation and thymectomy (TPTX) with no higher morbidity when compared to the standard procedures. The observed superiority of TPTX is flawed due to different definitions of outcomes, varying follow up periods and different surgical treatment strategies (with and without thymectomy). ⋯ sHPT is a disease with a high incidence in patients with chronic renal failure. Even a small difference in outcomes will be of clinical relevance. To assess sufficient data about the rate of recurrent sHPT after both methods, a multicentred, randomized controlled trial (MRCT) under standardized conditions is mandatory. Due to the existing uncertainties the calculated number of patients necessary in each treatment arm (n > 4000) makes it impossible to perform this study as a confirmatory trial. Therefore estimates of different outcomes are performed using a pilot MRCT comparing 50 versus 50 randomized patients in order to establish a hypothesis that can be tested thereafter. If TPTX proves to have a lower rate of recurrent sHPT, no relevant disadvantages and no higher morbidity than TPTX+AT, current surgical practice may be changed.
