[Show abstract][Hide abstract] ABSTRACT: The aim of the study is to describe the cognition of breast cancer with respect to knowledge, beliefs, attitudes and behavior in a group of gestational age Turkish women. A questionnaire survey was therefore performed on 201 randomly selected women registered to the health database in Aydin. In age, marital status, and occupation were found to significantly impact on breast self-examination (BSE) performance, which should still be considered as an important tool for early diagnosis, although it does not substitute clinical examination and education. As delayed diagnosis is the leading problem in the management of disease, well-structured education should be supported to increase awareness of breast cancer. Given to the remarkable role of nurses in the community on women's health, a more focused approach on education of young female populations by nurses in Turkey should be considered.

[Show abstract][Hide abstract] ABSTRACT: In this study, we investigated the effects of synchronous anastomosis on intestinal healing in experimental colonic resection. Sprague-Dawley rats were randomized into 3 groups; control (group I), single anastomosis (group II) and synchronous (double) anastomosis (group III). Single and proximal anastomoses were located 3 cm distal to caecum, and distal anastomoses were done 3 cm distal to them. On the 7th postoperative day, bursting pressure, hydroxyproline level and histology of the anastomotic site were assessed. Bursting pressures and hydroxyproline levels indicated that impaired healing of proximal anastomoses in group III was evident. Proximal anastomoses in group III had the lowest hydroxyproline value and bursting pressure level. Significant fibrosis was observed in the histological examination of distal anastomoses in group III. Double colonic anastomoses is not as safe as single anastomoses and involves additional risk. The healing of proximal anastomosis is significantly altered after experimental synchronous resection.
[Show abstract][Hide abstract] ABSTRACT: C-reactive protein (CRP) is used as a marker of intestinal ischaemia. This study evaluated whether CRP levels can be used to detect ischaemia-induced (strangulated) intestinal obstruction and subsequent bacterial translocation.
Forty-eight rats, divided into four groups underwent the following procedures: anaesthesia alone (native controls), laparotomy (sham-operated controls), or surgical induction of simple or strangulated intestinal obstruction (simple and strangulated obstruction groups, respectively). Blood samples were collected for culture and serum CRP analysis. In addition, liver and mesenteric lymph node (MLN) specimens were collected for culture, to determine the presence of bacterial translocation; and ileal segments, for histopathological investigation.
CRP levels and rates of bacterial translocation, expressed as colony forming units (cfu) per gram wet tissue, were higher in both intestinal obstruction groups than in the native and sham-operated control groups (P < 0.001 for both). The increases in CRP levels paralleled increases in the number of cfu in the MLN and liver cultures (P < 0.01). Compared to controls, animals in the obstruction groups also had a higher incidence of positive blood cultures (P < 0.005) and greater histopathologic evidence of inflammatory infiltration of the lamina propria (P < 0.01). However, no significant difference between the simple and strangulated obstruction groups was observed.
CRP levels increase with the severity of bacterial translocation in acute intestinal obstruction but do not permit discrimination between simple and strangulated intestinal obstruction.

[Show abstract][Hide abstract] ABSTRACT: Elevated intra-abdominal pressure and colostomy have adverse effects on colonic anastomoses. The aim of the present study was to investigate the effects of laparoscopic colon surgery with and without diverting colostomy on healing of colonic anastomoses in an experimental model.
Thirty-six male rats were divided into three equal groups: group 1, control (colonic anastomosis and anaesthesia for 180 min only); group 2, 180 min pneumoperitoneum and colonic anastomosis; and group 3, similar to group 2 with a proximal colostomy. On day 7, bursting pressures, tissue hydroxyproline and nitric oxide concentrations and histopathological inflammation scores were determined and compared.
Mean bursting pressures were higher in the control group than the two pneumoperitoneum groups (P=0.0003). Mean tissue hydroxyproline concentrations showed no difference (P>0.05). Mean tissue nitric oxide concentrations were significantly increased in the control group (P=0.0013). Histopathological scores demonstrated increased inflammatory response in group 3 compared to the controls (P=0.0009).
Pneumoperitoneum delays collagen maturation and impairs anastomotic strength in the colon. Following pneumoperitoneum, performance of a diverting loop colostomy to protect the anastomosis will not have additional detrimental effects on anastomotic healing.

[Show abstract][Hide abstract] ABSTRACT: The role of nitric oxide (NO) in bacterial translocation (BT) associated with acute pancreatitis is controversial. We investigated the effects of the NO synthase substrate, L-arginine, and the NO synthase inhibitor, N-nitro-L-arginine methyl ester (L-NAME), on BT in caerulein-induced acute pancreatitis in rats.
Acute pancreatitis was induced by subcutaneous injections of caerulein (12 microg/kg) at 6-hour intervals for 2 days. Subcutaneous injections of L-arginine (100 mg/kg) or L-NAME (10 mg/kg) were administeredonce daily for 2 days. At 48 h, pancreatic injury and BT to the mesenteric lymph nodes (MLN), liver, and peritoneum were assessed.
Compared with controls, rats that received caerulein injections alone had increased BT to the MLN and pancreatic inflammatory changes. L-Arginine significantly reduced the inflammation and BT caused by caerulein. L-NAME did not significantly alter pancreatic inflammation. Although caerulein + L-NAME-treated rats had increased BT to the peritoneum, MLN, and liver compared with controls, rates of BT did not significantly differ between caerulein alone- and caerulein + L-NAME-treated rats.
In acute edematous pancreatitis, BT is increased and is regulated by NO. NO substrates limit BT and pancreatic inflammation associated with acute pancreatitis, probably by their bactericidal actions and ability to improve pancreatic blood flow.
[Show abstract][Hide abstract] ABSTRACT: This study was performed to describe a new model of strangulation obstruction mimicking the situations relevant to abdominal hernias. The strangulation obstruction was induced either by intra-abdominal ligation of an ileal segment 2 cm in length (n = 20) or by a pursestring suture around a fascial defect with a strangulated intestinal loop placed subcutaneously (n = 20). Ten animals served as sham operated controls (n = 10). All animals were euthanized at 12 h postoperatively; strangulated ileum segments were collected for histopathological examination. Microscopic injury scores were similar in both strangulation groups, which were significantly different from the control group (p <.001). The model described here seems to be appropriate for use in further experimental studies concerning strangulation obstruction injury and its consequences, with the added advantage of visualization of the strangulated intestinal loop beneath the skin.

[Show abstract][Hide abstract] ABSTRACT: Behcet' s Disease (BD ) is a complex multisystemic disease, which is characterized by recurrent oral and genital aphteous ulcers and iritis in which vasculitis can also be one of the possible clinical manifestations. A thirty seven year-old female patient with incomplete BD was admitted to emergency service, with intra-abdominal hemorrhage more severe than that would be expected, with the degree of related trauma. We decided to manage the patient conservatively, observing vital signs, haemogram, computed tomography (CT) and angiography instead. Subcapsular hematomas were detected in the right and left lobes of the liver. No data was encountered in the literature and textbooks referring to liver trauma with BD, except a case of fatal hemobilia. H ere in we present a liver trauma case with hemorrhage and hepatic fragility due to vasculitis in Behcet' s disease and review the literature. Key words: liver trauma, incomplete Behcet' s disease

[Show abstract][Hide abstract] ABSTRACT: Obstructive jaundice promotes bacterial translocation from the gut, but the role of nitric oxide is controversial in this process. We studied the effects of nitric oxide synthase substrate, L-arginine, and nitric oxide synthase inhibitor, N(G)-nitro-L-arginine methyl ester, on bacterial translocation in bile duct ligated rats. The animals were randomized into five groups; control, sham, common bile duct ligation alone, nitric oxide inhibition, and nitric oxide supplementation. Obstructive jaundice was performed with common bile duct ligation. L-arginine or N(G)-nitro-L-arginine methyl ester was injected once daily for 14 days. Blood bilirubin level, liver histology, and bacterial translocation to the mesenteric lymph nodes as well as to the liver were assessed. The L-arginine supplemented group had the lowest bacterial translocation rate, but the most prominent hepatic fibrosis. Nitric oxide inhibition increased bacterial translocation to the mesenteric lymph nodes. Therefore, the administration of nitric oxide donor or inhibitor acts as a significant regulatory factor for bacterial translocation in obstructive jaundice.
