Background and Aims: Thyroid malignancy detected incidentally in patients who are operated for thyrotoxicosis has been reported at different rates. The aim of this study was to investigate the rate of incidental thyroid carcinoma in thyrotoxic patients managed with surgery in our institution. Methods: Of the 375 thyrotoxic patients who had thyroid surgery between the years of 1997–2004, 70.7% were females and 29.3% were males. Among thyrotoxic patients 65.3% (n = 245) had toxic multinodular goiter (TMG), 16.8% (n = 63) had toxic adenoma (TA) and 17.9% (n = 67) had Graves’ disease. Results: Twenty-six (6.9%) of all thyrotoxic patients had thyroid carcinoma. Eighteen (7.3%) of TMG, 4 (6.3%) of TA and 4 (6%) of Graves’ disease patients had thyroid carcinoma. Histologic examination revealed 18 papillary (9 microscopic), 5 follicular, 2 hurthle cell and 1 anaplastic carcinoma. Conclusion: In our study, incidental thyroid carcinoma was found in 6.9% of subjects with thyrotoxicosis. Papillary thyroid microcarcinomas constituted 34.6% (26/9) of these newly diagnosed thyroid carcinomas. The incidence of thyroid carcinoma was not higher in subjects with Graves’ disease compared to TMG and TA. The rate of incidental thyroid carcinoma in subjects with thyrotoxicosis treated with surgery was similar to previous studies reported from different countries.

Background: Hyperthermic intra-peritoneal chemotherapy (HIPEC) performed in patients with peritoneal carcinomatosis has a cytotoxic effect on tumour cells. This cytotoxic effect also adversely affects the wound healing of anastomosis, which is frequently undertaken in this patient group, and causes anastomotic leakage and intestinal fistulas. Platelet-rich plasma (PRP) gel has been used in wound healing and has shown efficacy. We investigated the effect of PRP gel on colon anastomosis healing in rats treated with 5-fluorouracil (5-FU). Methods: Twenty-four rats were divided into three groups, each containing eight rats: group 1 (control) underwent colon anastomosis alone; group 2 (5-FU) underwent a colon anastomosis and HIPEC; and group 3 (5-FU + PRP) underwent a colon anastomosis and HIPEC and received topical PRP gel. The rats were sacrificed on the post-operative day 7 and the anastomotic bursting pressure (ABP) was measured. Tissue samples were obtained to measure the hydroxyproline level and investigate the histopathological changes on the anastomosis line. Results: ABP was higher in the control and 5-FU + PRP groups than in the 5-FU group (P = 0.009, P = 0.047). The tissue hydroxyproline levels were higher in the control and 5-FU + PRP groups than in the 5-FU group (P = 0.001, P = 0.030). The histopathological findings of the 5-FU + PRP group were better than those of the 5-FU group. Conclusion: This study showed that the application of PRP gel to colon anastomoses increased ABP in rats treated with HIPEC using 5-FU. It also showed positive effects on anastomotic healing by increasing the tissue hydroxyproline levels on the anastomosis line and reducing the inflammatory response.

Objective: Gastric cancer is among the most common human cancers with high mortality rates. ADAM10, a member of the ADAM (a disintegrin and metalloproteinase) family has also been found to be associated with gastric carcinoma and has been suggested as a potential therapeutic target. Here, we investigated the association of ADAM10 expression with prognosis in gastric adenocarcinoma patients that underwent gastric resection with D2 lymph node dissection. Methods: Total 86 consecutive patients that underwent resection for gastric adenocarcinoma were included. Immunohistochemical ADAM10 expression and its association with clinicopathological parameters were analyzed. Univariate and multivariate analyses and survival analyses were performed using SPSS ver.22. Results: High grade tumors, advanced stage tumors and diffuse type tumors showed significantly worse prognosis. A statistically significant association between ADAM10 expression and overall survival (OS) was observed in the univariate analysis, however, this association did not maintain its significance in the multivariate analysis. No statistically significant association was found ADAM-10 expression and clinicopathological parameters. Conclusion: Immunohistochemical ADAM10 expression may be used as a prognostic marker in gastric adenocarcinoma, however, introduction of a standardized immunohistochemical scoring system seems to be necessary for evaluation of ADAM10 staining. doi: https://doi.org/10.12669/pjms.37.2.3613 How to cite this:Alakus H, Kaya M, Ozer H, Egilmez HR, Karadayi K.
