Pyloric gland adenoma of gallbladder-reports of two cases and a brief review of literature.

Adenomas of the gallbladder are uncommon benign epithelial neoplasms. Rarely, they can give rise to gallbladder cancer, which is the most common malignancy of the biliary tract, carrying a poor prognosis and decreased survival. Here we report the case histories of two patients, 40-year-old and 53-year-old males who presented with >1 cm gallbladder polyps, which were detected and confirmed using various imaging studies.

Pathological complete response after neoadjuvant chemotherapy with trastuzumab-containing regimen in gastric cancer: a case report.

We report a 49-year-old Chinese male with locally advanced gastric adenocarcinoma achieving pathological complete response after neoadjuvant chemotherapy with trastuzumab-containing regimen. He underwent esophagogastroduodenoscopy in September 2009, which revealed a 2-cm gastric ulcer on the lesser curvature proximal to angularis. Biopsy of gastric ulcer showed moderately differentiated adenocarcinoma with overexpression of human epidermal growth factor receptor 2 (HER2) by immunohistochemistry and fluorescence in situ hybridization.

Histopathologic evaluation of the canine prostate following electrovaporization.

Purpose: Transurethral electrovaporization of the prostate (TVP) for symptomatic benign prostatic hypertrophy (BPH) has proven to be efficacious with minimal patient morbidity. When compared to transurethral resection of the prostate (TURP), TVP demonstrates comparable postoperative flow rates, American Urologic Association (AUA) symptom score indices, and a potential cost savings. However, in the human studies it has not been possible to correlate these clinical parameters with procedure-related histopathologic changes in the prostate immediately postoperative or during wound healing.

Availability and selection of donors for pediatric heart transplantation.

Methods: Applying generally accepted criteria for selection of adult heart donors, we conducted a retrospective study of brain-dead infants and children for assessment of suitability as donors for heart transplantation. Cardiac histopathologic studies were evaluated in all subjects undergoing autopsy.

Results: In 5 years there were 58 such patients, the majority of whom had head injury, near-drowning, near-miss sudden infant death syndrome, infection, or asphyxia.

A new concept for anastomosis of the fallopian tube: tissue reconstruction with nonpenetrating, arcuate, legged clips in the rat model.

Objective: To evaluate the titanium Kirsch-Zhu microclip microsurgical reanastomoses of the fallopian tubes.

Design: Compare the reanastomoses of the rat uterine horn between Kirsch-Zhu clips (Cushman Engineering, Albuquerque, NM) (group A) and conventional suture microsurgical techniques (group B).

Setting: Microsurgery Research Laboratory, Loma Linda University Medical Center, Loma Linda, California.

Nonpenetrating, arcuate-legged clip reconstruction of the rat uterine horn.

A new method for reconstructing rat uterine horn was developed in which nonpenetrating, arcuate-legged clips are applied in interrupted fashion to everted seromuscular edges, forming an elastomeric flanged joint. This anastomosis has unusual physical and morphologic properties, with improved tissue healing and luminal restitution. Clipping is easier than suturing, and resulted in equivalent fertility rate (50-60%) and litter size.

Effects of angiographic needle size and subsequent catheter insertion on arterial walls. An in vitro experiment in human cadavers.

Rationale And Objectives: It is widely believed that down-sizing catheters, and possibly needles, will decrease damage to the entry vessel in the performance of angiography. The purposes of this in vitro experiment are to determine if smaller needles produce less arterial wall damage than larger needles and to assess the influence of subsequent catheter insertion.

Methods: Each iliac artery pair from 35 fresh human cadavers was punctured three times with an 18-g needle and three times with a 21-g needle, for a total of 210 punctures.

Use of angiographic needles with or without stylets: pathologic assessment of vessel walls after puncture.

There is controversy as to whether angiographic needles without stylets produce more arterial damage than those with stylets. Iliac arteries from 15 fresh human cadavers were punctured 56 times with either an 18-gauge angiographic needle with a stylet or one without a stylet (28 punctures with each needle type). These puncture sites were serially sectioned and examined microscopically.
