The skills required for laparoscopic surgery are amenable to simulator-based training. Several computerized devices are now available. We hypothesized that the LAPSIM simulator can be shown to distinguish novice from experienced laparoscopic surgeons, thus establishing construct validity. We tested residents of all levels and attending laparoscopic(More)
The ideal mesh for laparoscopic ventral hernia repair is not yet identified. We laparoscopically placed polypropylene (PPM), expanded polytetrafluoroethylene (ePTFE), and polyester with antiadhesive collagen layer (PCO) in eight pigs using sutures and tacks for fixation. After 28-day survival, we compared adhesion formation, fibrous ingrowth, and shrinkage(More)
BACKGROUND To our knowledge, there have been no previous studies addressing the indications for and the results of treatment of patients with cerebral palsy and concomitant kyphosis or lordosis without scoliosis. The purpose of the present study was to identify the indications for and the results of treatment of patients with cerebral palsy who have a(More)
The sensitivity of the CellSoft computer-assisted sperm analysis (CASA) system to detect changes in rat sperm motion was evaluated. CASA motion endpoints were measured in cauda epididymal sperm from Long-Evans rats treated with each of three known male reproductive toxicants reported to affect the epididymis and epididymal sperm motility:(More)
OBJECTIVE To evaluate the impact of electronic standardized chemotherapy templates on incidence and types of prescribing errors. DESIGN A quasi-experimental interrupted time series with segmented regression. SETTING A 700-bed multidisciplinary tertiary care hospital with an ambulatory cancer center. PARTICIPANTS A multidisciplinary team including(More)
Factorization theory is a prominent field of mathematics; however, most previous research in this area lies in the commutative case. Noncom-mutative factorization theory is a relatively new topic of interest. This paper examines the factorization properties of noncommutative atomic semigroups of integral matrices. In particular, semigroups with determinant(More)
Trichobezoar is a rare cause of small bowel obstruction, whereby a mass forms most commonly in the stomach and duodenum of young females, from ingestion of hair, a condition known as trichophagia. We present a case of recurrent small bowel obstruction due to a residual hair mass that was removed surgically in a young female patient who had a laparotomy and(More)
