OBJECTIVE To test the hypothesis that enhanced postexercise vasodilatation is related to sympathetic drive to resistance vessels and to fast marathon performance. DESIGN Prospective field study before and after running a marathon. PARTICIPANTS 51 healthy amateur runners who volunteered to participate. The fastest competitor finished fourth, the slowest(More)
Total disc replacement has become an option for the treatment of degenerative disc disease of the lumbar spine. A new generation of implants has been developed that can be implanted through minimally invasive anterior approaches to the lumbar levels L2/3, L3/4, L4/5 and L5/S1. However mid- and long-term data are still lacking. This paper describes the(More)
PURPOSE The purpose of this study was to assess the mid-term clinical and radiological results as well as patient safety in terms of complication and reoperation rates in patients treated with a novel anterior stand-alone fusion (ASAF) device (Synfix-LR, DePuy Synthes, West Chester, PA, USA) in a cohort of patients with predominant and intractable low back(More)
OBJECTIVE Anterior approaches to the lumbar spine for the treatment of various degenerative or postoperative abnormalities associated with low back pain have always been a matter of debate. They are known to be associated with considerable surgical trauma, high postoperative morbidity, and, occasionally, unacceptably high complication rates. In 1997, we(More)
Percutaneous endoscopic discectomy is a new technique for removing "contained" lumbar disc herniations (those in which the outer border of the anulus fibrosus is intact) and small "noncontained" lumbar disc herniations (those at the level of the disc space and occupying less than one-third of the sagittal diameter of the spinal canal) through a(More)
OBJECTIVE In many retrospective and prospective observational studies, laparoscopic cholecystectomy (LC) compares favorably with conventional cholecystectomy (CC), with respect to length of hospital stay, postoperative pain, and pulmonary function, indicating a diminished operative trauma. Comparison of laboratory findings (stress hormones, blood glucose,(More)
STUDY DESIGN A series of patients were prospectively studied to determine the morbidity and possible complications of minimally invasive anterior lumbar interbody fusion by two new microsurgical approaches (retroperitoneal for segments L2-L3, L3-L4, and L4-L5, and transperitoneal for L5-S1). OBJECTIVES To investigate the feasibility of performing an(More)
Although vasopressin increases vital organ blood flow during cardiopulmonary resuscitation (CPR), endocardial perfusion remains suboptimal. This study was designed to assess the effects of vasopressin versus a combination of vasopressin and nitroglycerin on vital organ blood flow in a porcine model of CPR. After 4 min of cardiac arrest, and 3 min of(More)
STUDY DESIGN Prospective study analyzing midterm clinical results of total lumbar disc replacement (ProDisc II) for different indications. OBJECTIVES To assess functional outcome after total lumbar disc replacement (TDR) treated for varying indications. SUMMARY OF BACKGROUND DATA Despite its frequent use and increasing popularity, indications and(More)
