    Background: Endocan is a recently introduced marker of endothelial dysfunction. The objective of this study was to compare serum endocan levels in patients with restless legs syndrome (RLS) and control subjects in order to elucidate whether RLS is associated with endothelial dysfunction. Methods: A total of 31 drug naïve female patients with RLS and 31 age- and BMI-matched women were included in the study. Patients with pathological or physiological conditions or with a history of medication use that could potentially influence endothelial functions were excluded, as well as those with alcohol or drug abuse history. The two groups were compared with routine blood tests and serum endocan levels. Results: Patients with RLS had lower serum endocan levels than the controls (P=0.037). There was a negative bivariate correlation between RLS severity score and serum endocan levels (r=-0.406, P=0.023). While white blood cell count was significantly higher in RLS group, 25-hydroxy vitamin D3, vitamin B12, transferrin saturation rate, and HDL-cholesterol were significantly lower. Creatininemia and diastolic blood pressure were also marginally insignificantly lower in RLS group. Due to the presence of differences between two groups in these variables, a linear regression analysis was performed that showed a positive association between endocan and creatininemia (β=0.310, P=0.022), and a negative association between endocan and RLS (β=-0.502, P,0.001). Conclusion: The results of this study seem to suggest that patients with RLS may have better endothelial functions when compared with the general population and that these patients may be better protected against atherosclerosis

    Aim: To search whether calcium channel blockers (CCBs) are associated with lower hemoglobin levels in chronic kidney disease (CKD) patients who are not on renal replacement therapy (RRT), vitamin D and anti-anemic treatment. Patients and methods: CKD patients were classified into two groups. Patients on CCBs treatment (103 patients) and patients not using CCBs (104 patients) were compared cross-sectionally regarding clinical findings, complete blood count (CBC), biochemistry and regular medication use. Patients with polycystic kidney disease, comorbidities that could influence CBC other than iron deficiency of obscure origin, patients receiving RRT, erythropoietin (EPO), vitamin D, phosphate binders and drugs that could influence CBC were excluded. Under dependent variable of CCB use, all significantly different independent variables were subjected to multivariate binary logistic regression analysis (MBLRA). Results: Lower hemoglobin, lower bilirubinemia, higher serum EPO, higher systolic blood pressure were observed in CCB users. Two groups were similar concerning age, gender, BMI, CKD etiology, CKD stage, pretibial edema prevalence, cardiothoracic index, diastolic blood pressure, corrected reticulocyte count, BUN, creatinine, eGFR, proBNP, parathormone, alkaline phosphatase, phosphorous, corrected calcemia, sCRP, relative EPO deficiency and prevalence of relative EPO deficient patients. Groups were comparable regarding comorbidities, types and usage frequencies of all antihypertensive medications other than CCBs. Higher systolic blood pressure and lower hemoglobin were significantly associated with CCB use after MBLRA. Conclusions: Hemoglobin was significantly lower in CCB users compared to non-users, among CKD patients who did not receive RRT, EPO, phosphate binders, vitamin D, iron, vitamin B12 and folic acid.

    The Role of Staged Cryosurgery and Three-Dimensional Computed Tomography Integrated Navigation System in the Surgical Management of Severe Involvement of Craniofacial Polyostotic Fibrous Dysplasia
    (2020-01-01T00:00:00Z) Dündar, Tolga Turan; YILDIZ, KEMALETTİN; DÜNDAR, TOLGA TURAN; MEHDIZADE, TURAN; GÜNEREN, ETHEM
    Fibrous dysplasia (FD) is a developmental bone disorder caused by the hamartamatous proliferation of bone-forming cells. A 29-year-old male patient with diagnosis of FD was admitted to our clinic with the symptoms of severe craniomaxillofacial involvement of FD beginning from last year. Neurological examination revealed diplopia, horizontal nystagmus, conductive hearing loss, and partial vision loss. In his medical history, it was reported that he had undergone intramedullary nailing operation in his left femur due to a pathological fracture approximately 8 years ago in the orthopedics clinic of our institution. The patient underwent 3 consecutive surgeries by our plastic and neurosurgical team. The patient was followed-up in the neuro-intensive care unit between the surgical sessions and 1 week after the last operation. Afterwards, he was transferred to the neurosurgical department. No postoperative complication was detected. The preoperative signs were recovered. During his 6th month follow-up control-visit, all his preoperative symptoms were improved. In addition, the patient was satisfied with his postoperative cosmetic improvement. In conclusion, virtual surgical planning and intraoperative surgical navigation systems can make the challenging cases possible to operate with increasing

    Generation of Bone Tissue Using Adipose Tissue-derived Stem Cells
    (2021-07-01T00:00:00Z) Baygol, Emre Gonenc; GÜNEREN, Ethem; Karaaltin, Mehmet Veli; Canter, Halil Ibrahim; Ozturk, Kahraman; Ovali, Ercument; Ozpur, Mustafa Aykut; YILDIZ, KEMALETTİN; Eyuboglu, Fatma; GÜNEREN, ETHEM; YILDIZ, KEMALETTİN
    Objective: Bone grafts and even bone substitutes do not meet all of the requirements of bony reconstructions. The aim of this study was to generate bone tissue from autologous adipose tissue-derived mesenchymal stem cells (ATDMSCs) and decellularised bone allografts. Methods: A 1.5 cm bone defect developed in the middle third of the rabbit's ulna. Reconstructions were carried out using miniplate and screws and interpositional autogenous bone grafts according to the designs of the groups: (1) No touch, (2) cryopreserved, (3) decellularised and (4) ATDMSCs-implanted decellularised bones. Before implantation, ATDMSCs in the last group were labelled with Q-dot and identified microscopically. Results: Graft recovery and irregular callus formation were observed in the first, second and forth groups. In the first group, the organisation of Haversian systems, the structure of the lacunae and the presence of canaliculi ossiums were observed; in the second group, approximately 40% of the Haversian canals contained blood vessels, and canaliculi ossiums in the form of thin filaments were found in 90% of the microscopically examined areas; in the third group, most Haversian canals were empty, most osteocyte canals were devoid of cells, and canaliculi ossiums were absent; in the fourth group, some of the Haversian canals contained blood vessels, and there were partly lacunae containing cells due to decellularisation, whereas in approximately 50% of the examined microscope areas, the presence of canaliculi ossiums with evidence of mesenchymal stem cells differentiated into osteocytes was demonstrated by Q-dot traced cells. Conclusion: In this study, the establishment of a proper niche environment for adipose-derived mesenchymal cells promotes their development into osteogenic cells.

    Effects of Different Concentrations of Injectable Collagenase Enzyme on Capsular Tissue Around Silicone Implants: A Preliminary Experimental Study for the Development of a New Treatment Strategy
    (2016-02-01T00:00:00Z) Yesiloglu, Nebil; Temiz, Gokhan; Sarici, Murat; YILDIZ, KEMALETTİN; Sirinoglu, Hakan; Guvercin, Emre; Akpinar, Ali Cem; Filinte, Gaye Taylan; FİLİNTE, DENİZ; YILDIZ, KEMALETTİN
    In recent studies, collagen organization was blamed for the formation of capsular contracture which is still a challenging problem after silicone implant-based breast operations. In this study, effects of different concentrations of collagenase enzyme derived from Clostridium histolyticum on the capsular tissue formation around the silicone implants were investigated. The injectable form of collagenase has a routine clinical use in the treatment of both Dupuytren-s and Peyronie-s diseases.

    Foreign body is rarely seen in tendon sheaths. An unusual case of embedded metallic foreign body in the right extensor pollicis longus tendon sheath that induced symptoms mimicking De-Quervain-s disease was cured after surgical removal of the foreign body and reported here.
