    (2016-06-01T00:00:00Z) Destek, SABAHATTİN; Gul, Vahit Onur; Ahioglu, Serkan; Erbil, Yesim; DESTEK, SABAHATTİN
    Esophageal melanosis which is characterized by melanocytic proliferation in the squamous epithelium of the esophagus and melanin accumulatin of esophageal mucosa (EM) is a rare disease of the digestive system. Although esophageal melanosis is considered to be a benign disease, its etiology is not cleared and has been reported to be the precursor lesion of esophageal primary melanomas. In this report, we aimed to note esophageal melanosis in a 55-year-old female case who applied to our clinic with difficulty in swallowing, burning behind the breastbone in the stomach, heartburn, indigestion, and pain in the upper abdomen after endoscopic and pathologic evaluation. Complaints dropped with anti-acid therapy and case was followed by intermittent endoscopic procedures because of precursor melanocytic lesions.

    Using pentraxin-3 for diagnosing acute appendicitis and predicting perforation: A prospective comparative methodological study.
    (2020-01-01T00:00:00Z) Gul, VO; Destek, SABAHATTİN; DESTEK, SABAHATTİN
    BACKGROUND: In this study, we aimed to investigate the diagnostic performance of pentraxin-3 for acute appendicitis, and the predictive performance for perforation in patients with acute appendicitis, compared with white blood cell count, high-sensitivity C-reactive protein and interleukin-6 (IL-6). METHODS: This study was a prospective methodological study, in which we studied the accuracies of the serum levels of pentraxin-3, white blood cell count, interleukin-6 and high-sensitivity C-reactive protein in estimating acute appendicitis, and in estimating perforation in patients with acute appendicitis. We designed the control group with the patients diagnosed inguinal hernia and admitted for elective surgery. Receiver operating characteristics analysis was used to compare the diagnostic accuracies and predictive performances. RESULTS: Receiver operating characteristics analysis revealed that the Pentraxin-3 level >3.67 ng/mL showed the sensitivity of 95.5% and specificity of 100.0% for diagnosing acute appendicitis, with an area under the curve of 0.993 (95% CI 0.967–1.000). Also, the Pentraxin-3 level >9.56 ng/mL showed the sensitivity of 92.9%, and the specificity of 87.1% for the prediction of the perforation, with an area under the curve of 0.820 (95% CI 0.736–0.886). CONCLUSION: The diagnostic performance of Pentraxin-3 for acute appendicitis and the predictive performance for perforation were higher than white blood cell count, high-sensitivity C-reactive protein and interleukin-6.

    Necrobiosis lipoidica is a granulomatous skin disease whose etiology and pathogenesis are not fully explained. The association of necrobiosis lipoidica with diabetes mellitus is frequently discussed and it is thought that microangiopathy plays an important role. Although there are many treatment options, there is no standard treatment model. In this study; a 43-year-old female patient with common skin lesions and punch biopsy and necrobiosis lipoidica diagnosis was presented. The patient was found to have concomitant diabetes mellitus with necrobiosis lipoidica. After treatment, diabetes mellitus clinic resolves but the necrobiosis lipoidica does not fully recover; Autoimmune hepatitis was detected and immunosuppressive treatment was given and the patient-s treatment was provided. In this case report, etiology and treatment of necrobiosis lipoidica have been discussed based on this case.

    S100A4 May Be a Good Prognostic Marker and a Therapeutic Target for Colon Cancer
    (2018-01-01T00:00:00Z) DESTEK, SABAHATTİN; Gul, Vahit Onur; DESTEK, SABAHATTİN
    Background. Globally, the colorectal cancers rank the third in terms of cancer incidence and rank the fourth in cancer-associated deaths. S100A4, an important member of the S100 protein family, serves to promote tumor progression and metastasis. By conducting this study, we aim to examine the role of S100A4 in the prognosis of colon cancer and to demonstrate its prognostic significance. Methods. Tissue samples of colon cancer from 148 patients who underwent colon resection due to colon cancer were analyzed by immunohistochemical staining to determine the protein expression levels of S100A4. The protein expression levels of S100A4 in tumor tissue werematched with the clinicopathologic factors including patient survival. Results. Cytoplasmic expression of S100A4 protein was demonstrated in the tumor tissue of 132 patients (89.2%) out of a total of 148 study patients. Statistically, the expression levels of the cytoplasmic S100A4 protein correlated significantly with the TNM stages and patient survival. The distribution of the S100A4 protein staining in the tumor tissue was associated with the age groups, tumor localization, TNMstaging, and patient survival with statistical significance. The levels of S100A4 protein expressionwere found to be an independent prognostic factor for TNM staging and poor survival. Conclusion. Expression of the S100A4 protein in colon cancers may be an indicator of tumor progression and lymph node metastasis and may be useful for predicting the overall survival of the patients with colon cancer. In patients with colon cancer, it may be used as an indicator of poor prognosis.

    Sinusectomy and primary closure versus excision and primary closure in pilonidal sinus disease: a retrospective cohort study
    (2020-01-01T00:00:00Z) Erol, Arzu; Goncu, Beyza S.; Hazer, Baki; ROSBERG, DERYA BURCU HAZER; DESTEK, SABAHATTİN
    Background Various surgical procedures are available for the treatment of pilonidal sinus diseases (PSD), but the best surgical approach remains controversial. Minimally invasive surgical procedures are more popular than surgery. This study aimed to evaluate the efficacy of sinusectomy with primary closure (SPC) in comparison with excision and primary closure (EPC) in primary or recurrent cases. Materials and methods This single-center retrospective cohort study was conducted with two cohort groups in which 351 patients with PSD underwent either SPC or EPC. The two procedures were compared according to the presence of short-term complications and recurrence of PSD. Results Of the patients, 134 underwent EPC and 217 underwent SPC. The length of stay and the wound healing time were significantly longer in the EPC group than in the SPC group. The occurrence rates of wound site infection and abscess were significantly higher in the EPC group than in the SPC group; however, seroma was statistically significantly more common in the SPC group than in the EPC group. The recurrence rates were 18.7% and 5.5% in the EPC and SPC groups, respectively. Conclusion SPC is an efficient procedure for the treatment of patients with PSD showing simple and complicated disease patterns.

    Analysis of Appendiceal Neoplasms on 3544 Appendectomy Specimens for Acute Appendicitis: Retrospective Cohort Study of a Single Institution
    BACKGROUND Appendiceal neoplasms are rare and generally determined in appendectomy specimens for acute appendicitis. Depending on a tumor's histopathology and size, appendectomy or right hemicolectomy are the surgical treatment options. Adenocarcinomas, mucinous neoplasms, goblet cell carcinoids and neuroendocrine tumors are the types of the primary appendiceal neoplasm histopathology. In this study, we aimed to determine the incidence of appendiceal neoplasms in an acute appendicitis cohort. Also, histopathological distributions, demographic data, preoperative radiological diagnosis, and intraoperative findings were revealed for analysis, retrospectively. MATERIAL AND METHODS Between October 2011 and September 2017, 3554 appendectomies were performed for acute appendicitis in Bezmialem University Hospital, Istanbul Turkey. The medical records of these consecutive 3554 patients were evaluated retrospectively. After the histopathological analysis of the appendectomy specimens, a total of 28 patients were detected as having appendiceal neoplasm including appendiceal adenocarcinoma, low grade mucinous neoplasia, and appendiceal neuroendocrine tumors. RESULTS Appendiceal neoplasms were determined in 28 out of 3554 acute appendicitis patients with an incidence of 0.78%. According to the histopathological types, 3 of the cases (10.7%) were appendiceal adenocarcinoma, 8 of the cases (28.5%) were low grade mucinous neoplasia, and 17 of the cases (60.8%) were neuroendocrine tumors. The overall incidence of the appendiceal neuroendocrine tumors was 0.48%. CONCLUSIONS The information obtained from our study suggests that pathological examination of the specimen may not be necessary if there is no doubt according to preoperative radiological diagnosis and/or intraoperative findings of the surgeon.
