Background: PERITONEAL cytology has received little attention in the literature, but it may be an additional useful means in evaluating patients with primary gastric cancer. The aim of this study was to examine the diagnostic accuracy of PERITONEAL fluid lavage cytology in detecting PERITONEAL SEEDING in patients with gastric adenocarcinoma.Methods: A total of 50 patients with gastric adenocarcinoma who were candidates for laparotomy based on the findings of computed tomographic examination were recruited. Diagnostic PERITONEAL lavage (DPL) was performed just before laparotomy and the PERITONEAL lavage fluid was sent for cytological examination for presence or absence of malignant cells. Findings in terms of PERITONEAL involvement during laparotomy were regarded as the standard results.Results: DPL cytology was positive for the presence of malignant cells in the PERITONEAL fluid in 25 cases (50%). According to the intraoperative findings 22 patients (44%) had PERITONEAL metastatic disease, whereas in 28 patients (56%) no gross indicator of metastasis was detected. The sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio and negative likelihood ratio of cytology in detecting PERITONEAL SEEDING were 59%, 57%, 52%, 64%, 1.38 and 1.40, respectively. The agreement between cytology and diagnostic laparotomy was 58%.Conclusion: According to the findings of the present study PERITONEAL lavage solely is not a proper diagnostic method for early recognition of resectable/nonresectable gastric cancers.

Cerebellar pilocytic Astrocytoma is a benign tumor, acounts for 80% of all cerebellar Astrocytoma, and has a relatively good prognosis. This tumor usually presents with Ataxia and in the case of hydrocephaly with raised intracranial pressure signs such as headeach, and vomiting. Treatment of this tumor is complete resection and if hydrocephally is present V.P. shunt should be inserted. In the case of recurrence or tumor SEEDING radiotherapy is recommended. SEEDING of cerbellar Astrocytoma has been reported rarerly. Spontaneous regression of chiasmatic pilocytic Astrocytoma associated with neurofibromatosis type I has been reported but Spontaneous regression of cerebellar Astrocytic tumor without neurofibromatosis has been reported very rarely in the literature. In this report a young patient with SEEDING of cerebellar Astrocytoma in the lumbosacral region with severe neurological deficit who has recovered spontaneously without any treatment is presented. This case is intresting for both SEEDING and spontaneous regression of tumor.

Disseminated PERITONEAL leiomyomatosis (DPL) is a very rare condition that almost always occurs in young women subjected to an altered hormonal milieu, usually pregnancy. To the surgeon, D00PL may appear as metastases; the possibility of DPL should be considered whenever PERITONEAL nodules are encountered in a young woman, particularly if she is pregnant. Here we present the case report of a 35-year-old woman with DPL, spontaneously regressing after total hysterectomy and bilateral salpingo-oophorectomy.

A 14 years old boy who had a ventriculo-PERITONEAL shunt since the age of 5 months, was hospitalized due to headaches, nausea, vomiting and abdominal distension. In abdominal CT and sonographic evaluation, pancreatic pseudo cyst or mesenteric cyst were suspected. Evaluation of the shunt by radionuclide, however, was diagnostic and revealed a pseudo cyst at the PERITONEAL end of the shunt. The patient was successfully treated by surgical intervention

This study was conducted during two years (2007-2009) in Shawoor Agricultural Research Station on a siltyclay soil. Experiment conducted in split plots in a Randomized Complete Blocks Design in three replications.Main plots were planting methods including centrifugal broadcaster (P1), centrifugal broadcaster+furrower (P2), seed drill (P3), seed drill+furrower (P4), three lines bed drilling (P5) and four lines bed drilling (P6).Subplots were included seed rates of 120, 160, 200 and 240 kg.ha-1. The results showed that P2 method with 14.91 litter.ha-1 and P3 method with 5.02 litter.ha-1 had the highest and lowest fuel consumption respectively. P3 method with 1.462 h.ha-1 and P5 method with 0.620 h.ha-1 required maximum and minimum total operation time respectively. P2 method with 0.684 ha.h-1 had minimum field capacity. Field capacity of P5 and P6 with averagely 1.67 ha.h-1 was maximum. Field capacity of all drilling methods (P3, P4, P5 and P6) was significantly more than that of broadcasting methods (P1 and P2). The highest seed spacing uniformity (87.2%) was belonged to P6 method and the lowest value (54.7%) was for P1 method. By using drilling methods of P3 and P5 (or P6) instead of P1 method total cost was reduced 41% and 29% respectively. The results of variance analysis of data showed that the difference between planting methods in case of wheat grain yield and yield components was not significant. However, the seed rate had significant effect on some yield components. Suggestion for cropping of wheat Chamran variety in silty-clay soil in Khuzestan province, used P5, P6 and P3 methods are recommended respectively with seed rate of 120 - 160 kg.ha-1.
