BACKGROUND: Xanthogranulomatous cholecystitis (XGC) is a destructive inflammatory disease of the gallbladder that can mimic gallbladder carcinoma. METHODS: We present the case of a 35-year-old Hispanic male complaining of right upper quadrant pain and jaundice for 2 months prior to admission. He denied a history of fever, nausea/ vomiting, and weight loss. The past medical history was relevant only for diabetes. He had no previous history of jaundice or previous operations. RESULTS: CA19-9 was slightly elevated (52 U/mL). Abdominal ultrasonography showed an irregular thickening of the gallbladder wall and no gallstones were detected. CT scan also revealed an irregular thickening of the wall of the gallbladder body suggestive of malignancy. At laparotomy, the mass was adherent to the duodenum and colon, and although the frozen section biopsy was negative, the intraoperative findings were suggestive of malignancy, and the patient underwent left liver trisegmentectomy, resection of the common bile duct and Roux-en-Y hepaticojejunostomy. Pathological examination unexpectedly revealed XGC without malignancy. CONCLUSIONS: Preoperative and intraoperative differential diagnosis of XGC from gallbladder carcinoma remains a challenge when it is associated with inflammatory involvement of surrounding tissues. Since gallbladder carcinoma and XGC may coexist, radical resection is justified when malignancy cannot be completely ruled out.

Herein we consider the existence of solutions to second-order, two-point boundary value problems （BVPs） for systems of ordinary differential inclusions. Some new Bernstein-Nagumo conditions are presented that ensure a priori bounds on the derivative of solutions to the differential inclusion. These a priori bound results are then applied, in conjunction with appropriate topological methods, to prove some new existence theorems for solutions to systems of BVPs for differential inclusions. The new conditions allow of the treatment of systems of BVPs without growth restrictions.

AIM:To examine whether the ob/ob mouse model of obesity is accompanied by enteric nervous system ab-normalities such as altered motility METHODS:The study examined the distribution of the P2X 2 receptor (P2X 2 R) in myenteric neurons of female ob/ob mice. Specifically, we used immunohistochemistry to analyze the co-expression of the P2X 2 R with neuronal nitric oxide synthase (nNOS), choline acetyltrans-ferase (ChAT), and calretinin (CalR) in neurons of the small intestine myenteric plexus in ob/ob and control female mice In these sections, we used scanning confocal microscopy to analyze the co-localization of these markers as well as the neuronal density (cm 2 ) and area profile (μm2) of P2X 2 R-positive neurons In addition, enteric neurons were labeled using the nicotinamide adenine dinucleotide (NA H) diaphorase method and analyzed with light microscopy as an alternate means by which to analyze neuronal density and areaRESULTS:In the present study, we observed a 29 6% increase in the body weight of the ob/ob animals (OG) compared to the control group (CG) In addition, the average small intestine area was increased by approxi-mately 29 6% in the OG compared to the CG Immu-noreactivity (IR) for the P2X 2 R, nNOS, ChAT and CalR was detectable in the myenteric plexus, as well as in the smooth muscle, in both groups This IR appeared to be mainly cytoplasmic and was also associated with the cell membrane of the myenteric plexus neurons, where it outlined the neuronal cell bodies and their processes P2X 2 R-IR was observed to co-localize 100% with that for nNOS, ChAT and CalR in neurons of both groups In the ob/ob group, however, we observed that the neuronal density (neuron/cm 2 ) of P2X 2 R-IR cells was in-creased by 62% compared to CG, while that of NOS-IR and ChAT-IR neurons was reduced by 49% and 57%, respectively, compared to control mice The neuronal density of CalR-IR neurons was not different between the groups Morphometric studies further demonstrated that the

AIM： To determine the and clinical features of prevalence, histologic types primary epithelial tumours of the vermiform appendix in a predominantly black population.METHODS： All cases of primary tumours of the appendix identified by review of the histopathology records at the University of the West Indies between January 1987 and June 2007 were selected. Relevant pathologic and clinical data were extracted with supplementation from patient charts where available. Non-epithelial tumours were excluded. The total number of appendectomy specimens over the period was also ascertained.RESULTS： Forty-two primary epithelial tumours were identified out of 6 824 appendectomies yielding a prevalence rate of approximately 0.62%. Welldifferentiated neuroendocrine cell tumours （carcinoids, 47.6%） and benign non-endocrine cell tumours （adenomas, 45.2%） were most common with nearly equal frequency. The median age was 43 years, with no sex predilection. Carcinoid tumours occurred in younger patients （mean age 32 years）, with a male-to-female ratio of 1.2：1. A clinical diagnosis of acute appendicitis was the most common reason for appendectomy （57.1%） and was histologically confirmed in 75% （18 of 24） of cases. In total, 16.7% of cases were diagnosed after incidental appendectomy.CONCLUSION： Appendiceal epithelial tumours are rare in our experience, and are represented principally by carcinoid turnours and adenornas. Carcinoid tumours occurred in younger patients but were slightly more common in men than women. Tumours were not suspected clinically and were diagnosed incidentally in specimens submitted for acute appendicitis supporting the need for histological evaluation in all resection specimens.

The utilization of RAPD and ISSR molecular markers is proposed to initiate studies of genetic variability in Phrynops hilarii（Chelidae） and Trachemys dorbigni（Emydidae）, two species of fresh water turtles distributed in South America. Three primers of RAPD and four of ISSR were selected and the amplified products of these markers were evaluated by electrophoretic runs in agarose and polyacrylamide gels. The levels of heterozygosity, Shannon index and different allele numbers were slightly higher in P. hilarii for both types of markers. Levels of polymorphism were also higher in P. hilarii than T. dorbigni and both were elevated compared to those recorded for other species. The fact that similar results were obtained with both types of markers for all estimates of diversity highlights the usefulness and validity of the RAPD technique. The molecular markers used were found potentially useful for analysing future temporal and spatial distribution of genetic diversity in both species, expanding scales work.
