Item Pathology, Classification, Clinical Manifestations and Prognosis of Langerhan's Cell Histiocytosis: A Single Center Experience(2022) Hasbay, Bermal; Kocer, Nazim Emrah; Kayaselcuk, Fazilet; Canpolat, Emine Tuba; Buyukkurt, Nurhilal; Erbay, AyseObjective: The aim of the study is to raise awareness about clinical features, histopathological and radiological analyzes and treatment details of this rare disease. Methods: A total of 55 Langerhans cell histiocytosis patients, diagnosed between the year 2006 and October 2020 in our department were included in the study. The patients were evaluated in terms of age, gender, tumor localization, risk groups, treatment modalities, recurrence, and outcome of the disease. Results: Twenty-three out of 55 patients were children and 32 were adults. The ages of the patients were between 7 months and 72 years. Thirty-seven of the cases were male and 18 were female. The most common clinical complaint in both groups was pain and swelling. The duration between the onset of the patient complaints and admission to the hospital varies between 7 days-12 months in children, and 10 days-23 years in adults. Forty-three of the cases had single organ involvement and 12 had multiorgan involvement. The most frequently affected organ in both groups was bone. Forty of the 55 patients had follow-up data and the treatment modalities are as follows: Nine patients radiotherapy, 8 patients chemotherapy+steroid, 7 patients chemotherapy, 2 patients chemotherapy+radiotherapy+steroid, 1 patient steroid, 2 patients chemotherapy+radiotherapy. Eleven patients were followed up without additional treatment after surgery. Median follow-up from the time of biopsy was 45.9 months in children and 41.9 months in adults. Conclusions: As a result, diagnosis requires a high degree of suspicion and final diagnosis is based on the histological examination of the lesions and biopsies.Item T-Cell Lymphoblastic Lymphoma Showing Aberrant Synaptophysin Expression in a Child(2020) Kocer, Nazim Emrah; Hasbay, Bermal; Kayaselcuk, Fazilet; 0000-0002-1180-3840; 0000-0002-5943-9283; 31852036; AAE-2550-2021; AAM-5436-2021Item The relationship between fibrosis and nodule structure and esophageal varices(2019) Cosar, Arif Mansur; Yakar, Tolga; Serin, Ender; Ozer, Birol; Kayaselcuk, Fazilet; 31290750Background/Aims: The aim of the present study was to evaluate the histopathological findings of cirrhosis together with clinical and laboratory parameters, and to investigate their relationship with esophageal varices that are portal hypertension findings. Materials and Methods: A total of 67 (42 male and 25 female) patients who were diagnosed with cirrhosis were included in the study. The mean age of the patients was 51.6 +/- 19.0 (1-81) years. The biopsy specimens of the patients were graded in terms of fibrosis, nodularity, loss of portal area, central venous loss, inflammation, and steatosis. The spleen sizes were graded ultrasonographically, and the esophageal varices were graded endoscopically. Results: In the multivariate regression analysis, there was a correlation between the advanced disease stage (Child-Pugh score odds ratio (OR): 1.47, 95% confidence interval (CI): 1.018-2.121, p=0.040), presence of micronodularity (OR: 0.318, 95% CI: 0.120-0.842, p=0.021), grade of central venous loss (OR: 5.231, 95% CI: 1.132-24.176, p=0.034), and presence of esophageal varicose veins. Conclusion: Although thrombocytopenia and splenomegaly may predict the presence of large esophageal varices, cirrhosis histopathology is the main factor in the presence of varices.Item Does bee pollen cause to eosinophilic gastroenteropathy?(2015) Guc, Belgin Usta; Asilsoy, Suna; Canan, Oguz; Kayaselcuk, Fazilet; 26568697Bee pollen is given to children by mothers in order to strengthen their immune systems. There are no studies related with the side effects of bee polen in the literature. In this article, the literature was reviewed by presenting a case of allergic eosinophilic gastropathy related with bee polen. A 5-year old child was admitted due to abdominal pain. Edema was detected on the eyelids and pretibial region. In laboratory investigations, pathology was not detected in terms of hepatic and renal causes that would explain the protein loss of the patient diagnosed with hypoproteinemia and hypoalbuminemia. Urticaria was detected during the follow-up visit. When the history of the patient was deepened, it was learned that bee pollen was given to the patient every day. The total eosinophil count was found to be 1 800/mm(3). Allergic gastroenteropathy was considered because of hypereosinophilia and severe abdominal pain and endoscopy was performed. Biopsy revealed abundant eosinophils in the whole gastric mucosa. A diagnosis of allergic eosinophilic gastropathy was made. Bee polen was discontinued. Abdominal pain and edema disappeared in five days. Four weeks later, the levels of serum albumin and total eosinophil returned to normal.Item Duodenitis caused by Sarcina ventriculi in a case with Celiac disease and selective IgA deficiency(2017) Canan, Oguz; Ozkale, Murat; Kayaselcuk, Fazilet; 0000-0002-1180-3840; 0000-0003-0625-1057; 0000-0003-0614-4497; AAE-2550-2021; A-7806-2016; AAI-9386-2021Sarcina ventriculi is a gram-positive, obligate anaerobic bacteria first documented in the human gastrointestinal tract in 1842. Sarcina ventriculi are found to be associated with delayed gastric emptying and gastric outlet obstruction Up to date numerous cases of fatal disease have been attributed to this organism in the veterinary literature, but only a few human cases have been documented. Herein we report a case of a 10-year-old girl patient who was diagnosed Celiac disease, selective IgA deficiency and Sarcina ventriculi duodenitis. To the best of our knowledge the association Celiac disease and Sarcina ventriculi duodenitis has not been previously reported in children. Therefore, in the present study we want to draw attention to the importance of a rare coexistance of Celiac disease and Sarcina ventriculi duodenitis.
