On finite nonsolvable groups whose cyclic p-subgroups of equal order are conjugate
(Tubitak Scientific & Technological Research Council Turkey, 2022) Van der Waall, Robert; Sezer, Sezgin
The 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.
Polymethylmetacrylate Cement Augmentation of the Coccyx (Coccygeoplasty) for Fracture: A Case Report
(Galenos Publ House, 2020) Akar, Ezgi; Koban, Orkun; Ogrenci, Ahmet; Yilmaz, Mesut; Dalbayrak, Sedat
Background: Coccydynia is a painful condition of the sacrococcygeal region, with symptoms associated with sitting and rising from a seated position. It is frequently related to trauma and idiopathic causes, and the pain is mostly chronic. Pere utaneous vertebroplasty and sacroplasty are the methods that are widely used for treating compression fractures and sacral insufficiency fractures, respectively. However, the success of polymethylmethacrylate injection in the treatment of osteoporotic coccyx fractures and coccydynia is still unknown. Case Report: A 68-year-old man was admitted to our clinic with complaints of pain in the sacrococcygeal and perianal regions. In the imaging studies, a fracture line in the fifth sacral and first coccygeal segments was observed as evidenced by a bony edema. Since the patient's pain did not improve with conservative methods, we treated him with coccygeoplasty. No complication was encountered. The day after the operation, he was discharged from the hospital with complete pain relief. The patient confirmed having no pain on the third postoperative month and so did not need any analgesics. Conclusion: Coccyceoplasty may be a good treatment option for retractable pain in patients with acute or subacute osteoporotic coccygeal fractures and coccydinia with edema.
Radiographic Acetabulotrochanteric Distance Measurement as a Novel Method for Determining Leg Length Discrepancy in Patients with Hemiarthroplasty
(Turkish Joint Diseases Foundation, 2025) Yesil, Murat; Yüzügüldü, Uğur; Maralcan, Gokhan; Yılmaz, Bilge Kağan; Bütüner, İbrahim Ethem
Objectives: This study aims to evaluate the interobserver reliability and interobserver reproducibility of radiographic acetabulotrochanteric distance (ATD) measurement and to investigate its accuracy by comparing it with conventional radiographic methods used in leg length discrepancy (LLD) measurement. Patients and methods: Between January 2017 and January 2022, a total of 97 patients (39 males, 58 females; mean age: 77.8±7.1 years; range, 61 to 91 years) who underwent pelvic radiographic evaluation and hemiarthroplasty (HA) due to femoral neck fracture were retrospectively analyzed. For ATD measurement, the distance between the line connecting the upper cartilage of the acetabulum (AC) and the extreme point of the greater trochanter (GT) was used. The AC-GT measurement on both sides was compared with bottom of the ischial tuberosities-lesser trochanter (BI-LT), center of the femoral head-BI (CH-BI), inferior acetabular teardrops-LT (IT-LT) measurements. The agreement between the methods was examined with the intraclass correlation coefficient (CCI). Results: According to the AC-GT & BI-LT, AC-GT & BI-CH methods, there were very strong (ICC: 0.75), moderate (ICC: 0.69) and acceptable (ICC: 0.33) agreements, respectively. Significant agreement was found between all measurements (p<0.001). A positive correlation was detected in the correlation analysis of all measurements (p<0.001). Intra- and interobserver agreement for ATD measurement (AC-GT) was excellent (ICC: >0.8). Conclusion: The ATD measurement correlates well with known measurement techniques on pelvic radiography and can be used as an alternative to this method. It has excellent intra- and interobserver agreements. This method can predict LLD after HA, but does not consider other length differences in the lower limbs.
Regional Clinical and Biochemical Differences among Patients with Primary Hyperparathyroidism
(2017) Güngör, Bahadır Bülent; Emre, Ali Uğur; Girgin, Mustafa; Erbil, Yeşim; Karataş, Adem; Şimşek, Turgay; Erel, Serap
This study had been presented at the 6th ESES Biennial Scientific Meeting held in Cardiff (15-17 May 2014).Address for Correspondence: Dr. Özer Makay, Department of General Surgery, Division of Endocrine Surgery, Ege University School of Medicine, İzmir, TurkeyPhone: +90 232 390 50 50 Received: 13 July 2015 e-mail: ozer.makay@ege.edu.trAccepted: 27 January 2016 o DOI: Background: Environmental habitat may play a role in clinical disparities of primary hyperparathyroidism (pHPT) patients. 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, 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.
