Evaluation of the outcome of a proposed more physiological bypass surgery technique in morbid obesity: Long term 3 years follows up.

Background: Obesity is a chronic condition that affects millions globally; consequently, bariatric surgery is the key to this serious issue. Bariatric procedures are rapidly expanding in number and methods to address the recognized problems. So, it would make a sense for surgeons and patients if there is a more physiological bypass surgery technique in Morbid obesity.

Combined Unilateral Posteroventral Pallidotomy and Ventral Intermediate Nucleus Thalamotomy in Tremor-Dominant Parkinson's Disease versus Posteroventral Pallidotomy Alone: A Prospective Comparative Study.

Background: The optimum target in surgery for Parkinson's disease (PD) is still controversial, especially in patients with tremor-dominant PD. We aim to compare results in tremor-dominant patients undergoing pallidotomy vs. those undergoing simultaneous posteroventral pallidotomy (PVP) and ventral intermediate nucleus (VIM) thalamotomy.

Postoperative cognitive dysfunction in adult and elderly patients--general anesthesia vs subarachnoid or epidural analgesia.

This study compared the effect of general anesthesia or regional vertebral analgesia (subarachnoid or epidural) on postoperative cognitive function in 60 young adult (group A) and 60 elderly (group E) patients undergoing orthopedic and urologic surgery. Wechsler Adult Intelligence Scale-Revised for cognitive functions assessment was done preoperatively, and postoperatively; one day and three days after surgery. Variations in heart rate, blood pressure, arterial oxygen and carbon dioxide tensions, and pH as well as serum bicarbonate, sodium and potassium levels, were assessed at the same time intervals.
