Article Citation Count: 1Induced characters with equal degree constituents(Walter de Gruyter Gmbh, 2015) Gagola, Stephen M., Jr.; Sezer, SezginWe study the situation of a finite group G having a subgroup H with the property that each of its nonprincipal irreducible (complex) characters induce to G as a sum of irreducible characters all having the same degree. When this happens, the subgroup H either contains, or is contained in, the commutator subgroup G' of G. In any case, the normal closure H-G is always proper in G whenever H is proper (even when G is perfect), and H-G is solvable whenever this normal closure is a proper subgroup of G'.Article Citation Count: 0On finite nonsolvable groups whose cyclic p-subgroups of equal order are conjugate(Tubitak Scientific & Technological Research Council Turkey, 2022) Van der Waall, Robert; Sezer, SezginThe structure of the nonsolvable (P)-groups is completely described in this article. By definition, a finite group G is called a (P)-group if any two cyclic p-subgroups of the same order are conjugate in G, whenever p is a prime number dividing the order of G.Article Citation Count: 10Management of endocrine surgical disorders during COVID-19 pandemic: expert opinion for non-surgical options(Springer-verlag Italia Srl, 2022) Agcaoglu, Orhan; Sezer, Atakan; Makay, Ozer; Erdogan, Murat Faik; Bayram, Fahri; Guldiken, Sibel; Yazici, DilekPurpose The COVID-19 pandemic brought unprecedented conditions for overall health care systems by restricting resources for non-COVID-19 patients. As the burden of the disease escalates, routine elective surgeries are being cancelled. The aim of this paper was to provide a guideline for management of endocrine surgical disorders during a pandemic. Methods We used Delphi method with a nine-scale Likert scale on two rounds of voting involving 64 experienced eminent surgeons and endocrinologists who had the necessary experience to provide insight on endocrine disorder management. All voting was done by email using a standard questionnaire. Results Overall, 37 recommendations were voted on. In two rounds, all recommendations reached an agreement and were either endorsed or rejected. Endorsed statements include dietary change in primary hyperparathyroidism, Cinacalcet treatment in secondary hyperparathyroidism, alpha-blocker administration for pheochromocytoma, methimazole +/- beta-blocker combination for Graves' disease, and follow-up for fine-needle aspiration results of thyroid nodules indicated as Bethesda 3-4 cytological results and papillary microcarcinoma. Conclusion This survey summarizes expert opinion for the management of endocrine surgical conditions during unprecedented times when access to surgical treatment is severely disrupted. The statements are not applicable in circumstances in which surgical treatment is possible.Article Citation Count: 1On finite solvable groups whose cyclic p-subgroups of equal order are conjugate(Academic Press inc Elsevier Science, 2014) Sezer, SezginWe study the finite solvable groups G whose cyclic p-subgroups of the same order are conjugate in G whenever p is a prime number dividing the order of G.

Aims: To compare preoperative clinical symptoms and associated conditions and surgical findings in patients with pHPT, living in different geographical regions from the Black Sea, Mediterranean and Anatolia regions. Study Design: Retrospective, clinical-based multicentric study of 694 patients with pHPT. Methods: Patients from 23 centers and 8 different geographical regions were included. Data related to baseline demographics, clinical, pathologic and treatment characteristics of 8 regions were collected and included age, gender, residential data, symptoms, history of fracture, existence of brown tumor, serum total Ca and p levels, serum parathormone (PTH) levels, serum 25-OH vitamin D levels, bone mineral density, size of the resected abnormal parathyroid gland(s), histology, as well as the presence of ectopia, presence of dual adenoma, and multiple endocrine neoplasia (MEN)- or familial-related disease. Results: The median age was 54. Asymptomatic patient rate was 25%. The median PTH level was 232 pg/mL and serum total Ca was 11.4 mg/dL. Eighty-seven percent of patients had an adenoma and 90% of these had a single adenoma. Hyperplasia was detected in 79 patients and cancer in 9 patients. The median adenoma size was 16 mm. Significant parameters differing between regions were preoperative symptoms, serum Ca and p levels, and adenoma size. All patients from South-East Anatolia were symptomatic, while the lowest p values were reported from East Anatolia and the largest adenoma size, as well as highest Ca levels, were from Bulgaria. Conclusion: Habitat conditions vary between geographical regions. This affects the clinicopathological features of patients with pHPT.
