The approach to the inguinal canal through the preperitoneal space appears to be less invasive than the transinguinal anterior approach.
In this study, we investigated the contribution of vitamin K epoxide reductase (VKORC1) and cytochrome P450 2C9 (CYP2C9) genotypes, age, and body surface area (BSA) on warfarin dose requirements and in an adult Turkish population. Blood samples were collected from 100 Turkish patients with stable warfarin dose requirements and an international normalized ratio (INR) of the prothrombin time within the therapeutic range. Genetic analyses for CYP2C9 genotypes (*2 and *3 alleles) and VKORC1 -1639 G>A polymorphism were performed and venous INR determined. The mean warfarin daily dose requirement was higher in CYP2C9 homozygous wild-type patients, compared to those with the variant *3 allele (P < 0.05), similar to those with the variant *2 allele (P > 0.05) and highest in patients with the VKORC1 -1639 GG genotype compared to those with the GA genotype and the AA genotype (P < 0.01). The time to therapeutic INR was longer in CYP2C9 homozygous wild-type patients compared with those with the variant *2 and *3 alleles (P < 0.01), and longer in patients with the VKORC1 (position -1639) GG genotype compared with those with the GA genotype and the AA genotype (P < 0.01). The multivariate regression model including the variables of age (R (2) = 4.4%), BSA (R (2) = 27.4%), CYP2C9 (R (2) = 8.1%), and VKORC1 genotype (R (2) = 34.1%) produced the best model for estimating warfarin dose (R (2) = 60.4%). VKORC1 genotype and CYP2C9 polymorphism affect daily dose requirements and time to therapeutic INR in Turkish patients receiving warfarin for anticoagulation.
SUMMARY OBJECTIVE Tumor budding is a parameter that is increasingly understood in colorectal carcinomas. We aimed to investigate the relationship between tumor budding, prognostic factors, and survival METHODS A total of 185 patients who had undergone colorectal surgery were observed. Tumor budding, the tumor budding score, and the relationship between these and prognostic factors, and survival investigated. RESULTS Tumor budding was found in 91 (49.2%) cases. The relationship between the tumor budding score and histological grade, lymphovascular invasion, perineural invasion, pathological lymph node stage, and mortality rates were significant. CONCLUSION In our study, the relationship between tumor budding and survival is very strong. Considering these findings and the literature, the prognostic significance of tumor budding becomes clear and should be stated in pathology reports.
Inflammatory markers are elevated in acute coronary syndromes, and are also known to play a crucial role in the pathogenesis of neointimal proliferation and stent restenosis. Drug-eluting stents (DESs) have been shown to decrease stent restenosis in different studies. In this study, we aimed to investigate the effect of treatment with DESs on systemic inflammatory response in patients with unstable angina pectoris who underwent percutaneous coronary intervention (PCI). We compared plasma high-sensitivity C-reactive protein (hsCRP), human tumor necrosis factor alpha (Hu TNF-alpha), and interleukin 6 (IL-6) levels after DES (dexamethasone-eluting stent [DEXES], and sirolimuseluting stent [SES]) implantation with levels after bare metal stent (BMS) implantation. We performed PCI with a single stent in 90 patients (62 men; 59 +/- 9 years of age; n = 30 in the BMS group, n = 30 in the DEXES group, n = 30 in the SES group) who had acute coronary syndrome. Plasma hsCRP, Hu TNF-alpha, and IL-6 levels were determined before intervention and at 24 h, 48 h, and 1 week after PCI. The results were as follows. Plasma hsCRP levels at 48 h (11.19 +/- 4.54, 6.43 +/- 1.63 vs 6.23 +/- 2.69 mg/l, P = 0.001) after stent implantation were significantly higher in the BMS group than in the DES group; this effect persisted for 7 days (P = 0.001). Plasma Hu TNF-alpha levels at each time point were higher in the SES group than in the BMS and DEXES groups (P < 0.05). The time course of Hu TNF-alpha values was similar in all groups. Although IL-6 levels at baseline and at 24 and 48 h showed no statistically significant difference between the study groups, postprocedural values at 7 days were slightly statistically significant in the SES group (P = 0.045). Drug-eluting stents showed significantly lower plasma hsCRP levels after PCI compared with BMSs. This may reflect the potent effects of DESs on acute inflammatory reactions induced by PCI.
BACKGROUND: Acute pancreatitis is a disease with high morbidity and mortality, despite all the advances in technology. The overall mortality rate of acute pancreatitis is 10%, whereas the mortality rate in infected necrotizing pancreatitis is approximately 35%. In this study, we aimed to establish acute pancreatitis in rats in order to try out the alpha-tocopherol treatment protocol and to reveal the results biochemically and histopathologically. METHODS:Twenty-four male male Sprague-Dawley rats weighing between 300 and 350 g were used in the study. In Group 1, 80 µg/kg of normal saline was subcutaneously injected into eight rats; in Group 2, 80 µg/kg of cerulein was subcutaneously injected into eight rats; and in Group 3, 80 µg/kg of cerulein was subcutaneously injected into eight rats. In addition, 30 mg/kg of alpha-tocopherol was intraperitoneally injected into eight rats. RESULTS:The mean Schoenberg score, serum amylase, and lipase and Neutrophil Gelatinase-Associated Lipocalin (NGAL) levels were statistically significantly higher in Group 2 than in Group 1. The mean Schoenberg score and serum amylase and lipase levels were statistically significantly lower in Group 3 than in Group 2. CONCLUSION:In this experimental study rat model of cerulein-induced acute pancreatitis, 30 mg/kg of alpha-tocopherol was injected intraperitoneally to examine its effect on pancreatitis. The improvement was observed in the histopathological examination of pancreatic tissues. We think that alpha-tocopherol may have a therapeutic effect on pancreatic tissue.
Objective: Thyroid gland is an important endocrine gland and thyroid cancers (TC) are the most noteworthy disease of the thyroid gland. Although thyroid surgery is performed for most particularly for malignancy, thyroidectomies still maintain a large part of surgical operations. We aimed to investigate the incidence and subtypes of the thyroid cancers in present study, with our 10 years' experience of thyroid surgery. Methods: Data of patients who underwent thyroidectomy were retrospectively analyzed. The patients who underwent bilateral total thyroidectomy were included to the study. Patients' age, gender and histopathological results were recorded. According to the histopathological reports we divided the patients into two groups either as benign or malignant. Results: A total of 3632 patients were included in the study. 2999 (82.6%) patients were in benign group and 633(17.4%) patients were in malignant group. The subtypes of malignant tumors were papillary carcinoma in 591 (93.4%), medullary carcinoma in 16 (2.5%), follicular carcinoma in 14 (2.2%), oncocytic (hurtle cell) carcinoma in 7 (1.1%) and undifferentiated (anaplastic) in 5(0.8%) of the cases. Conclusion: Incidental thyroid cancers are not a rare entity after pathological examination of thyroid specimen after surgery. Therefore, we suggest careful evaluation and bilateral leb lobectomy ectomy in surgical treatment of thyroid conditions
Neuroendocrine tumor of the uterine cervix is a rare and aggressive malignancy. Despite controversial, multimodal treatment methods, prognosis and treatment outcomes are worst in advanced stages. We report an early-stage case treated with the multimodal approach. The nomenclature proposed for this tumor type in 1997 by the College of American Pathologists still has some points of discussion. As in our case some of the tumors cannot be defined exactly into small or large cell types, and this causes confusion at least for nomenclature purposes. A ‘mixed’ type for this tumor may be appropriate.
