Abstract
PURPOSE To determine the effects of information given before cesarean section on women's anxiety levels and their knowledge about informed consent regarding it. MATERIALS AND METHODS Sixty women who elected to undergo cesarean section were included in the study. The data were collected using the pregnancy-related clinical information form, informed consent form, cesarean information form, and State and Trait Anxiety Inventory. Kruskal-Wallis test, Mann-Whitney U test, chi-square test and Pearson correlation were used as statistical methods. RESULTS The women's knowledge scores before and after they were informed about cesarean section were 14.8 +/- 5.5 and 29.8 +/- 2.6, respectively (p < 0.05). Their state anxiety scores before and after they were informed about cesarean section were 28.4 +/- 6.6 and 28.0 +/- 5.9, respectively (p > 0.05). CONCLUSION It was determined that the participants' pre-training knowledge scores about cesarean section increased significantly after they were informed, and that their state and trait anxiety scores decreased very little after they were informed.

Abstract
The aim of this study was to investigate the beneficial effects of the fish oil (FO) supplementation on oxidative stress, sperm characteristics and histological alterations in the male reproductive system of rats against cisplatin (CP) toxicity. The rats were divided randomly into 4 equal groups (control, FO, CP and FO + CP). FO was orally administered at the dose of 1 softgel per rat per day for 14 days and CP was intraperitoneally given at the dose of 7 mg kg(-1) with a single injection. In CP + FO group, they were applicated at the same doses and times. The results showed that CP caused a significant oxidative damage via induction of lipid peroxidation and reduction in the antioxidant defence system potency in the testis tissue. In addition, sperm motility and sperm concentration significantly decreased but the abnormal sperm rate and histopathological testicular damage increased with CP treatment. On the other hand, FO treatment prevented oxidative, histopathological and spermatological effects of CP and reversed side effects of CP. In conclusion, FO supplementation had significant beneficial effects against CP toxicity on male reproductive system and toxic effects of CP can be prevented by FO treatment. Therefore, it appears that fish oil may be useful for the prevention and treatment of cisplatin-induced reproductive system toxicity.

Abstract
BACKGROUND The present study investigated the effects of (sun-dried organic apricot/SDOA) supplementation in chow on liver regeneration after partial hepatectomy/(PH) in rats. METHOD In this study, 28 female rats were randomized into four groups. On the 7th day of the study, group 1 underwent laparoscopic intervention while a PH was performed on the other three cohorts. On day 28, all rats were humanely killed. Blood and liver tissue samples were subjected to biochemical determinations, histological examinations, and measurement of tissue oxidative stress enzyme activity. RESULTS Serum levels of alanine transaminase (ALT), alkaline phosphatase (ALP), and liver tissue glutathione (GSH) activities were affected by PH and/or SDOA consumption (P < .05). Moderately staining cell counts in group 4 were significantly different from the other three groups (P < .05). However, no significant differences were detected among all groups in regard to aspartate aminotransferase (AST) serum levels or liver tissue superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT) or glutathione peroxidase (GSHpx) activities (P < .05). CONCLUSION The 5% SDOA supplementation over a 21-day feeding period showed a beneficial effect on liver regeneration in rats, as reflects by Ki-67 finding although there was no change in ALT or ALP or in liver tissue GSH activity.

Abstract
Clinical studies generally reveal a trend of variation in the reported prevalence of the palmaris longus (PL) muscle absence. The aim of this study was to find an answer to the question of whether the congenital absence of tendon would affect hand functions or not. A total of 585 subjects, comprised of 305 males and 280 females, were included in our study. Mean age was 8.9 ± 1.4 standard deviation within a range of 6-11. For both sexes, the groups were divided further into three subgroups including 6-7, 8-9, and 10-11 years of age ranges. The grip strength of each hand and pinch strength of all fingers of each subject were measured separately. The absence of PL tendon in the right hand was 35.4 % in females, 25.9 % in males, and 30.4 % in overall average. The distribution of absence of the palmaris longus muscle between both genders was statistically significant. The p value for the right hand was 0.013. The absence of PL tendon in the left hand was 37.5 % in females, 27.9 % in males, and an overall average of 32.5 %. The p value for the left hand was 0.017. In terms of grip strength, a comparison between females and males did not reveal a significant difference. The pinch strength of the second fingers of both hands did not show any difference in both sexes. Pinch strength of the third finger of the right hand was different only in girls of subgroup 6-7 ages (p = 0.024). In girls, the pinch strength of the fourth finger of the right hand of subgroups 6-7 and 10-11 ages showed difference (p = 0.009 and p = 0.026, respectively). In boys, the fourth finger in subgroup of 8-9 ages showed significant difference in both hands (p = 0.011). The fifth fingers of both hands were found different in males for only subgroup of 8-9 ages (p = 0.001). Pinch strength of the fifth finger of the right hand was different in females for only subgroups of 6-7 and 10-11 ages (p = 0.023 and p = 0.047, respectively). While grip strength of the hand was not affected in the case of absence of the palmaris longus, in both sexes, pinch strength of the fourth and fifth fingers of both hands decreased.

Abstract
BACKGROUND Bone is the most common metastatic site for breast cancer. AIM To determine the effectiveness of addition of chemotherapy to hormonal therapy in postmenopausal hormone receptor-positive breast cancer patients with isolated bone metastases. MATERIALS AND METHODS Between June 2001 and January 2007, 101 patients were classified into two groups according to initial treatment modalities; patients who received hormonotherapy only (group I) and chemotherapy followed by hormonotherapy (group II). The effect of treatment choice on clinical course, time to progression, and overall survival were evaluated. RESULTS There were 70 patients in group I and 31 patients in group II. Bone metastases in 27 patients (26.7%) were synchronous and the remainder were metachronous. The median follow-up time was 41 months. The two groups showed similar results when patients' tumor characteristics were compared. However, 81% of synchronous cases had upfront chemotherapy following hormonotherapy, whereas this ratio was only 12% in the metachronous group. All patients received systemic antiresorptive bisphosphonates whereas only 24 patients required palliative radiotherapy at some time during the course of their disease. In groups I and II, the median time to progression was 12 and 16 months (P: 0.96) and median overall survival was 41 and 40 months (P: 0.79), respectively. In HER-2-positive patients, a trend of prolongation of overall survival was observed in group II, but it was not statistically significant (P: 0.12). CONCLUSIONS Anti-hormonal therapy still seems to be considered as the ideal treatment of choice for postmenapousal breast cancer patients with isolated bone metastases.

Abstract
OBJECTIVE Postoperative adhesions still remain as a common and serious problem leading to morbidity, mortality and economic loss. Adhesions are the major cause of postoperative intestinal obstruction, infertility, and chronic pelvic pain. In this study, we aimed to compare adhesion prevention effects of pentoxyphylline, enoxaparin and methylene blue and to investigate the effects of these agents on angiogenesis, which is suggested as an important step in wound healing, in rat a uterine horn model. MATERIAL AND METHODS Forty female Wistar albino rats were randomized into four subgroups and underwent laparotomy. Adhesions developed following cauterization at the anti-mesenteric surfaces of both uterine horns. After 14 days, adhesions were investigated by using macroscopic, histopathological and immunohistochemical [vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), transforming growth factor (TGF-beta), platelet-derived growth factor (PDGF)] methods. RESULTS We found that enoxaparin significantly reduced adhesion formation. Pentoxyphylline had no significant effect on adhesion formation, whereas methylene blue had a significant decreasing effect on histopathologically determined adhesion markers and it may affect angiogenesis through PDGF. CONCLUSION Among three agents, which were intraperitoneally given by a single dose manner in order to prevent postoperative adhesions, methylene blue and enoxaparin exhibited a positive effect, while no such effect was shown with pentoxyphylline.

Abstract
α-Tocopherol and β-carotene are the best known and most widely used natural antioxidant substances. Apricot contains β-carotene, tocopherols and flavonoids. This experimental study was designed to investigate the protective effect of Malatya kabashi apricot in stress-induced injury in various tissues of rats. In total, 32 male Wistar albino rats were divided into four groups: control, apricot, stress and apricot-stress groups. Apricot was administrated to rats by gavage for 10 days in the apricot and apricot-stress groups. Then rats were kept at 4°C for 4 h in stress and apricot-stress groups. The rats were killed at the end of the experiment for biochemical and histological examinations. This study shows apricot supplementation decreased oxidative stress injury in both the stomach and intestine.

Abstract
OBJECTIVE Wound infection, flap necrosis rates and peripheral complete blood cell count changes related to intraoperative whole-blood transfusions were investigated. BACKGROUND Evidence is growing that whole-blood cell transfusions are immunosuppressive and predispose patients to postoperative infections. METHODS 102 female breast carcinoma patients with hemoglobin levels = 10 g/dl before modified radical mastectomy and < 10 g/dl intraoperatively but with no signs of oxygen debt were included. Group I included patients who had received two units of whole-blood transfusions intraoperatively. Patients who had received no transfusion were in group II. Peripheral complete blood cell count, wound infection rates and flap necrosis were compared. RESULTS Perioperative neutrophile and monocyte count increased in both groups. This increase was especially significant in the transfused group (p < 0.05). In both groups, these changes returned to normal levels on the tenth postoperative day. The decreased perioperative basophile count did not return to the baseline even on the tenth postoperative day in group I (p < 0.05). Lymphocyte count, and flap necrosis did not differ between the groups (p > 0.05). Wound infection seemed to take place and increase in the transfused group (p < 0.05). CONCLUSION Two units of whole-blood transfusions seem to increase wound infection and decrease basophile count in this series (Tab. 3, Ref. 30).

Abstract
AIM To investigate the clinical and pathological relevance of detection of circulating tumor cells (CTC) in the peripheral blood of gastric carcinoma patients before operation. PATIENTS AND METHODS Fifty patients with gastric adenocarcinoma were analysed prospectively. Patients were divided into two groups according to the extent of the tumor. Group I (unresectable) consisted of 22, and group II (resectable) consisted of 28 patients. Peripheral blood samples were collected pre-operatively from all 50 patients as well as from ten healthy controls and analyzed for carcinoembryonic antigen (CEA) and cytokeratin-19 (CK-19) messenger ribonucleic acids (mRNAs). Tumor localisation, stage, presence of signet cell formation, nodal metastases, serousal and lymphovascular invasion were recorded for all patients. RESULTS Expression of CK-19 was detected in 24 (48%), and CEA in 10 (20%) cases. Nine patients (40%) in group I and 15 (53.6%) in group II were positive for CK-19 expression. CEA expression was more frequent among group I patients (6 vs. 4 cases). There was no significant difference between the groups in the expression of CK-19 and CEA mRNA, tumor localisation, presence of signet formation, and presence and extent of nodal metastases. Patients with major vascular invasion (MVI) expressed significantly higher levels of CTC mRNA compared to those without MVI (p = 0.023 for CEA, and p = 0.009 for CK-19). The median 1 and 2-year survival was 9.5 and 10.5 months for group I, and 20 and 28.5 months for group II, respectively (p = 0.001). The mean survival was 6.7 months for patients with MVI, and 30.2 months for those without MVI (p = 0.0001). CONCLUSIONS High levels of CTCs were observed in patients with MVI invasion, rather than other causes of unresectability. It can be suggested that expression of both CEA and CK-19 in the peripheral blood of gastric cancer patients are strong predictors of MVI and significantly worse survival rates.

Abstract
OBJECTIVE To investigate the effects of cyclooxygenase (COX) inhibitors including celecoxib, indomethacin, and nimesulide on postoperative adhesion formation. MATERIAL AND METHODS Forty-eight female Wistar-Albino rats were randomly divided into four groups: control (saline solution), celecoxib, indomethacin, and nimesulide groups. The uterine horns of rats were traumatized with unipolar electrocautery. Drugs of each group and saline in the control group were insillated on travmatized areas of horns as intraperitoneally. After three weeks, the extent and severity of adhesions with a standardized scoring system were evaluated. RESULTS The extent and severity of postoperative adhesions were significantly reduced in nimesulide group compared with the control group. The extent but not severity of adhesions in rats given indomethacin was significantly reduced. Celecoxib showed no significant reduction in the extent and severity of adhesions. CONCLUSION Nimesulide is more effective than the other COX inhibitors in the prevention of postoperative adhesions in rats.

Abstract
OBJECTIVE The term arthrogryposis multiplex congenita (AMC) refers to multiple joint contractures present at birth. AMC is not a specific disorder but is the consequence of neurological, muscular, connective tissue, and skeletal abnormalities or intrauterine crowding, which may lead to limitation of fetal joint mobility and the development of contractures. METHODS Cases referred to our perinatology department for detailed examination were retrospectively analyzed. RESULTS Twelve cases with AMC were detected during the antenatal period. The ultrasound features related to the "lack of movement" included limb abnormalities (multiple contractures, clenched hands, and clubbed feet), short umbilical cord, polyhydramnios, pulmonary hypoplasia, camptodactyly, and micrognathia. Five of the early detected cases (71%) were found to have increased nuchal translucency or nuchal fold. All of the cases at the third trimester resulted in neonatal death. CONCLUSION First trimester screening may be useful for early diagnosis of AMC. Sonographic findings in late pregnancy might be helpful in predicting the prognosis. Due to the high recurrence risk, a specific screening program should be performed for the following pregnancies by examination of the fetus several times for movement and position of the limbs.

Abstract
OBJECTIVE The aim of this study was to analyze cases and determine the clinical significance of a prenatally detected single umbilical artery (SUA) in our population. MATERIALS AND METHODS All second and third trimester sonographic examinations carried out between January 2004 and September 2007 in our perinatology unit were reviewed. The postnatal results of the fetuses with SUA were obtained from the medical records and the patients. RESULTS From a total of 5,620 pregnant patients who were examined by ultrasound (US) scan between 15-36 weeks, a single umbilical artery was found in 45 cases, representing an incidence of 0.8%. Of these, 20 (45%) also presented with other malformations. There were six neonatal deaths, one fetal demise, and six terminations of pregnancy due to severe malformations in this group. Three cases with associated anomalies underwent surgery and one case required intensive care in the neonatal period. The only cytogenetic abnormality was trisomy 18 in one case. Six of 45 fetuses (13%) with single umbilical arteries had abnormal echocardiographic findings. In two of the fetuses associated anomalies (cleft palate and esophageal atresia) were detected after birth. In pregnancies without associated anomalies no aneuploidy was found and they were completely normal at birth and during the neonatal period. CONCLUSIONS Scanning the umbilical cord is one of the essential parts of US examination. As the rate of cardiac malformations seen with single umbilical arteries is high, fetal echocardiography should be performed in suspected cases. The newborn should be reexamined immediately after birth due to the possibility of undetected anomalies.

Abstract
OBJECTIVE The aim of this study was to compare the histopathologic features and surgical stage of endometrial carcinoma with tumor-free endometrial tissues. METHODS Data from the files of 80 patients with endometrial carcinoma who were managed at Haseki Training & Research Hospital between January 2001 and July 2007 were evaluated. We assessed tumor-free endometrium, stage, histologic type and grade, depth of myometrial invasion, peritoneal cytology, adnexal-cervical involvement, lymphovascular space invasion (LVSI), and lymph node metastases. RESULTS Twenty-nine patients (43%) with endometrial carcinoma had concomitant endometrial hyperplasia. Seven patients (10%) had one or more areas of metaplasia in the endometrium adjacent to the carcinoma. Endometrial carcinoma with atrophic background was significantly associated with aggressive histopathologic type (p < 0.04) and LVSI (p < 0.02). CONCLUSION The histological characteristics of non-tumoral endometrium were found to be critical in determining the type of aggressive tumor and LVSI in atrophy-associated carcinomas.

Abstract
The purpose of this study was to determine whether a measurable decrease in isokinetic (dynamic) and isometric (static) hand strengths occurs in carpal tunnel syndrome (CTS) patients. Eighteen CTS patients and 20 healthy controls were included in the study. Isokinetic (eccentric and concentric) and isometric grip and pinch strengths were measured with a Biodex System 3 dynamometer (Biodex Medical System, Inc. New York). All strength measurements, except isometric and isokinetic (concentric/eccentric) three-point pinch and isokinetic (concentric) tip pinch, revealed statistically significant differences between CTS patients and controls. Measurable decrease in hand strengths may exist in CTS despite normal manual assessments. Although both isokinetic (dynamic) and isometric (static) dynamometers are capable of detecting this decrease, neither technique seems better than the other.
