Abstract
Parathyroid allotransplantation is increasingly practiced for patients who have permanent hypoparathyroidsm. Parathyroid allotransplantation success is varied, and no defined criteria about immunologic monitoring for pre-/post-transplantation follow-up. This study sought to evaluate the possible role of immunological tests. Four unrelated recipients and one living donor who have chronic kidney disease were evaluated for HLA-typing, PRA, CXM tests to conduct parathyroid allotransplantation. Parathyroid glands were obtained and resected from the donor, then cells were isolated and cryopreserved. Upon histologic examination, cells were cultivated and injected into muscle of four recipients. Recipient's were followed for parathormone and calcium levels for four years. PRA screening were monitored and de novo DSA was evaluated as well. In two of the recipients, allografts continued to be functional more than four years. In one recipient, allograft remained functional for two years and another recipient lost function after one year. Two out four were negative for de novo DSA and three out of four of the recipients remained negative for PRA. Neither HLA-matching nor de novo DSA positivity and PRA screenings seems significant for successfull parathyroid allotransplantation. This study has considerable potential for immunological monitoring of parathyroid allotransplantation.

Abstract
INTRODUCTION Thyroid nodules are commonly seen. Our aim is to learn the behaviors and operational attitudes of surgeons approaching the thyroid nodules. In a literature search, our study is the first and only study performed merely on surgeons. MATERIALS- METODS This cross-sectional study was done between June 2014-January 2015. The questionnaire consists of 25 questions. Initially, general questions consisting of demographic findings were asked. In step 2, questions consisting of the index case and case variants were asked. Results were compared with American Thyroid Association, European Thyroid Association guidelines, and Australia survey results. In the last step, questions about thyroid operations were asked. RESULTS A total of 301 surgeons responded to the survey. The response rate was approximately 20%. Thirty nine were female and 262 were male. For the question that asks the diameter of the thyroid nodule that will require a thyroid fine needle aspiration biopsy (TFNAB), 47.5% of the surgeons will require a TFNAB for 1-2 cm solid nodules. 40.15% of the surgeons required a TFNAB regardless of size. 46.1% of the surgeons who required a TFNAB between 1 and 2 cm solid nodules also required scintigraphy at diagnosis of suppressed TSH case variant. CONCLUSION In this survey, we identified differences from up-to-date guidelines about approaching thyroid nodules and perioperative thyroid surgery. From our perspective, surgeons need updated training requirements. This can be done with updated seminars across the country. Thereby approaches may become standard and consequently patients may have qualified services.

Abstract
Pilonidal sinus is a very common inflammatory disease of the gluteal region. The ideal method of pilonidal sinus treatment should have a low recurrence rate with minimum excision. Moreover, the treatment method should have a short hospitalization time, should let the patient return to his normal life rapidly, should cause minimum loss of labour and should result a small scar only. In the presented review, modalities in pilonidal sinus treatment in the light of current information in the literature are evaluated.

Abstract
Background The aim of this study was to evaluate the prognostic importance of the metastatic lymph node ratio for stage III colon cancer patients and to find a cut-off value at which the overall survival and disease-free survival change. Material/Methods Patients with pathological stage III colon cancer were retrospectively evaluated for: age; preoperative values of Crp, Cea, Ca 19-9, and Afp; pathologic situation of vascular, perineural, lymphatic, and serosal involvement; and metastatic lymph node ratio values were calculated. Results The study included 58 stage III colon cancer patients: 20 (34.5%) females and 38 (65.5%) males were involved in the study. Multivariate analysis was applied to the following variables to evaluate significance for overall survival and disease-free survival: age, Crp, Cea, perineural invasion, and metastatic lymph node ratio. The metastatic lymph node ratio (<0.25 or ≥0.25) is the only independent variable significant for overall and disease-free survival. Conclusions Metastatic lymph node ratio is an ideal prognostic marker for stage III colon cancer patients, and 0.25 is the cut-off value for prognosis.

Abstract
PURPOSE Although the advantages of laparoscopic procedures has been well studied over the last two decade, laparoscopic appendectomy could not to be a standard therapy due to some disadvantages such as longer operative time and higher cost.The objective of our study is to re-evaluate the outcomes of laparoscopic versus open appendectomy with current data. METHODS Between January 2012 and July 2012, the data of the patients who had appendectomy were recorded prospectively. Patients' demographics, duration of procedure, length of hospital stay, need of analgesics, postoperative visual analogue scale scores and morbidity were assessed. RESULTS Of 241 patients, 120 (49.8%) underwent open and 121(50.2%) laparoscopic appendectomy. The operating time was similar for both groups (p=0.855). The visual analog scale scores of 1st (p=0.001), 6th (p=0.001) and 12th (p=0.028) hours were higher in open the appendectomy group. The total need of analgesics significantly was higher in open group (p=0.001).There was no statistical difference in terms of total morbidity rate between open and laparoscopic appendectomy groups (p=0.617). CONCLUSION Two operative techniques are similar in terms of length of hospital stay, operative time, and postoperative complications. Laparoscopic appendectomy reduces the need for analgesics and visual analog scale scores; therefore,it should be considered as the gold standard for surgical treatment of acute appendicitis.

Abstract
Background We evaluated the effects of local flax seed oil and glycerol application for reducing adhesion formation after thyroidectomy. Material/Method We randomly assigned 18 female Wistar albino rats (median weight: 275 g, median age: 4.5 mth) to 3 groups: 0.1 ml 0.9% NaCl, glycerol, and flax seed oil were sprayed in a perithyroidal area after thyroidectomy operation on all animals as anti-adhesive barriers. Rats were sacrificed on the postoperative 14th day and adhesions were evaluated macroscopically and microscopically. Results The median macroscopic adhesion score was 3.0±0.0 in the 0.9% NaCl group, 1.33±0.52 in the glycerol group, and 1.67±0.53 in the flax seed oil group. The median histopathological fibrosis scores were 2.33±0.82, 0.67±0.52, and 0.83±0.75, respectively. Both glycerol and flaxseed oil group macroscopic and microscopic scores were significantly lower than the 0.9% NaCl group (p<0.05). There was no significant difference among the groups (p>0.05). Conclusions Glycerol and flax seed oil both decrease the incidence of post-thyroidectomy adhesion in rats, but glycerol is more effective.

Abstract
Pilonidal sinus disease is a common disabling condition affecting the natal clefts of the buttocks. We analyze the role of fibrin glue in the treatment of selected patients with pilonidal sinus disease. Forty patients diagnosed with pilonidal sinus disease at Vakif Gureba Training and Research Hospital were treated between December 2007 and December 2011. Recurrence was noted in four patients (10%). Ninety percent of patients had no recurrence one year later (95% confidence interval: 0.85-0.95). This procedure is suggested as a first line of treatment for patients with no prior history of infection and who have only one sinus orifice.

Abstract
56 Background: HER2 overexpression observed in 10-25% of breast cancers is associated with rapid proliferation. HER2-targeted trastuzumab has been used in metastatic breast cancer, and since 2004 in early breast cancer. However, trastuzumab therapy is expensive and long lasting resulting sometimes in cardiac side effects. In this study we tried to find out whether there was a subgroup of early breast cancer patients trastuzumab could be omitted. Methods: Records of patients treated for HER2-positive breast cancer in Istanbul Medical School between Jan 2000 and Sept 2009 were retrospectively evaluated. Disease-free survival (DFS) and overall survival (OS) were calculated either from follow-ups, or by calling. Kaplan meier and LogRank tests have been used for comparison (P<0.05, 95% CI). Results: Follow up period was 32.2±14.9mo for trastuzumab group (TG, n:87) compared to 47.4±20.8mo for non-trastuzumab group (NTG, n:63) (P=0.0001). Groups were similar for age, menopausal status, size (T), histological grade and type, location, hormone responsiveness, presence of lymphovascular invasion, surgery, and use of local/systemic/hormonal therapy. NTG had more N0 cases (44.4% vs. 12.6%, P=0.0001), breast related deaths (15.9% vs. 5.7%, P=.042) and systemic metastases (27% vs. 13.8%, P=.043). Number of local recurrences was similar. Mean DFS and OS were significantly less in TG (P<0.0001). However differences between DFS and OS of groups were not significant despite a considerable increase for both in TG at fifth year (P=0.147, P=0.450). No difference in DFS and OS between TG and NTG was observed when patients who had chemotherapy and/or radiotherapy and/or hormonotherapy were compared to those who did not. OS was not different between TG and NTG for T1, T2, and T3 tumors and for patients ≤35y. But in N2 and N3 tumors, use of trastuzumab increased OS significantly (P=0.007). Conclusions: Both number of events and systemic relapses were less in TG but we could not find a significant difference in DFS and OS between TG and NTG in Turkish nonmetastatic cancers. Prolonged follow up might be necessary to search for the subgroup who would not benefit, if any, as an incremental benefit in both DFS and OS was observed with trastuzumab use at fifth year.
