Öğe Anaesthesia management in Moyamoya disease (a case presentation) [Moyamoya hastaliginda anestezi uygulamasi (olgu sunumu)](2003) Derbent A.; Demirag K.; Uyar M.; Kaya E.Moyamoya disease is a rare cerebrovascular occlusive disease. We aimed to present two cases of Moyamoya diagnosed patients undergoing general anaesthesia and emphasize important issues about the anaesthetic management of these patients. 28 year old male patient was admitted to the hospital with complaints of weakness in his left arm and leg. Preoperative examination revealed quadriparesia and disturbed consciousness and angiography revealed occlusion in internal carotid arteries bilaterally. Encephaloduroarteriocineangiosis operation was planned. The patient was observed with meticulous noninvasive monitorization. During induction of anesthesia atropine, fentanyl, thiopentone and vecuronium bromide were administered. Anaesthesia was maintained by sevoflurane in oxygen (O2) nitrous oxide (N2O) mixture. End tidal carbondioxide (ETCO2) level was kept between 35-40 mmHg. There was no complication during peroperative and postoperative period. 4.5 year old male child was hospitalized in order to investigate his growth retardation. During his follow up, MRI angiography revealed serious narrowing in cavernous segments of internal carotid arteries bilaterally. Encephaloduroarteriocineangiosis operation was planned. After meticulous noninvasive monitori-zation, induction of anaesthesia was achieved O2+N2O and no complication was observed during the peroperative and postoperative period. During anaesthetic management of these patients, it is crucial to avoid hypocapnia due to hyperventilation and steal phenomenon secondary to hypercapnia. Otherwise ischemia in frontoparietal region which is predominantly involved by Moyamoya disease may adversely affect the prognosis.Öğe Coronary injection ventriculography: Multiple coronary-cameral fistulas as a rare cause of stable angina pectoris(Elsevier B.V., 2016) Kocabas U.; Kaya E.; Akin M.Coronary-cameral fistula is a rare, abnormal fistulous communication between a coronary artery and a cardiac chamber or large vessel. Being mostly asymptomatic, corona-cameral fistulas can seldom cause myocardial ischemia, congestive heart failure, arrhythmias and infective endocarditis. We represent you a case of stable angina pectoris found to have multiple corona-cameral fistulas between left coronary arteries and left ventricle in conventional coronary angiography. © 2016 Elsevier B.V.Öğe Enterococcus gallinarum endocarditis: High-grade atrioventricular block as a early sign of bioprosthetic aortic valve endocarditis and aortic root abscess(Baycinar Medical Publishing, 2017) Kocabas U.; Kaya E.; Zoghi M.[No abstract available]Öğe Immediate provisional restoration fabrication for immediate implant loading using a modified technique: A clinical report(2010) Erhan Comlekoglu M.; Yucel Parlar A.; Gokce B.; Dundar M.; Kaya E.; Gunbay T.This article describes the immediate fabrication and placement of a provisional restoration, using a modified method for impressionmaking. An impression was made before surgery and provisional acrylic temporary restorations with composite resin frameworks were prepared on the solid-screw implant abutments. This article demonstrates this simple method and discusses the benefits of immediate provisionalization after surgery.Öğe Multicenter retrospective analysis of turkish patients with chronic myeloproliferative neoplasms [Kronik miyeloproliferatif neoplazi tanılı türk hastaların geriye dönük ve çok merkezli analizi](Turkish Society of Hematology, 2017) Soyer N.; Haznedaroğlu İ.C.; Cömert M.; Çekdemir D.; Yılmaz M.; Ünal A.; Çağlıyan G.; Bilgir O.; İlhan O.; Özdemirkıran F.; Kaya E.; Şahin F.; Vural F.; Saydam, G..Objective: Chronic myeloproliferative neoplasms (CMPNs) that include polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF) are Philadelphia-negative malignancies characterized by a clonal proliferation of one or several lineages. The aim of this report was to determine the demographic features, disease characteristics, treatment strategies, and survival rates of patients with CMPNs in Turkey. Materials and Methods: Across all of Turkey, 9 centers were enrolled in the study. We retrospectively evaluated 708 CMPN patients’ results including 390 with ET, 213 with PV, and 105 with PMF. Results: The JAK2V617F mutation was found positive in 86% of patients with PV, in 51.5% of patients with ET, and in 50.4% of patients with PMF. Thrombosis and bleeding at diagnosis occurred in 20.6% and 7.5% of PV patients, 15.1% and 9% of ET patients, and 9.5% and 10.4% of PMF patients, respectively. Six hundred and eight patients (85.9%) received cytoreductive therapy. The most commonly used drug was hydroxyurea (89.6%). Leukemic and fibrotic transformations occurred at rates of 0.6% and 13.2%. The estimated overall survival in PV, ET, and PMF patients was 89.7%, 85%, and 82.5% at 10 years, respectively. There were no significant differences between survival in ET, PV, and PMF patients at 10 years. Conclusion: Our patients’ results are generally compatible with the literature findings, except for the relatively high survival rate in PMF patients. Hydroxyurea was the most commonly used cytoreductive therapy. Our study reflects the demographic features, patient characteristics, treatments, and survival rates of Turkish CMPN patients. © 2017 by Turkish Society of Hematology.Öğe Outcomes of pneumatic retinopexy in rhegmatogenous retinal detachment [Yirtikli retina dekolmaninda pnömatik retinopeksi sonuçlari](2012) Nalçaci S.; Kaya E.; Afrashi F.; Erakgün T.; Menteş J.; Akkin C.Purpose: To evaluate the anatomic success rate of pneumatic retinopexy in rhegmatogenous retinal detachment and to determine the factors related to anatomic success. Material and Methods: 35 eyes of 35 phakic patients who had rhegmatogenous retinal detachment and who had been treated with pneumatic retinopexy were analysed retrospectively. In 28 eyes 0.3 cc pure perfluoropropane (C3F8) gas and in 7 eyes 0.3 cc pure sulfur hexafluoride (SF6) gas were injected intravitreally. The rate of anatomic success and complications were analyzed. Data was evaluated statistically with Chi-square and Fisher's exact test. Results: The mean age of patients was 55.97±10.71 (16 -75 year). All of 35 eyes were phakic. The mean number of retinal tears was 1.3 (1-3). All of them were located in the upper quadrant. The mean follow up period was 16.69±17.96 months (1-72 month). After the intravitreal gas injection; cryopexy was performed in 11 eyes and argon laser photocoagulation was performed in 24 eyes as additional treatment. Anatomic success rate was 65.7% following pneumatic retinopexy. 12 eyes needed additional operations such as pars plana vitrectomy or scleral buckling surgery. Anatomic success was obtained in all of the eyes with second surgery. The factors related to anatomic success rate were analyzed. Conclusions: Pneumatic retinopexy is an effective treatment in selected patients with phakic rhegmatogenous retinal detachment.Öğe Renal stem cells [Böbrek kök hücreleri](Turkish Society of Nephrology, 2017) Kaya E.; Şenol O.; Mir S.Kidney diseases, related to high morbidity and mortality, are one of the diseases that should be primarily investigated. Development of acute and chronic kidney diseases is due to lack of functioning renal repair mechanisms. Embryonic progenitor cells are precursors of renal cells that are able to differentiate to several types of nephron epithelium. Fetal renal progenitor cells are partially capable of self-renewal. In the adult human kidney, whole nephron regeneration is not possible. Progenitor-like cells continuously replace the cells that are lost physiologically or by damage. These cells have been differentiated to epithelial and endothelial cells in vitro. Transplantation of stem cells to the damaged kidney is one of the regenerative therapy options. In recent studies, it has been shown that chronic kidney disease, graft rejection and other kidney diseases could be treated and nephrons and other structures could be regenerated by stem cell therapy. Stem cells are the best candidates for the treatment of kidney diseases, organ transplantation and producing a functional organ. The success of this method is due to the ability of the cells to differentiate, to penetrate the existing tissue and the capacity of the cells to secrete renoprotective factors.Öğe Treatment of nonsyndromic dentigerous cysts in primary dentition(2011) Akay M.C.; Kaya E.; Zeytinoglu M.Objective: Dentigerous cysts are benign odontogenic cysts that are associated with the crowns of permanent teeth. They usually occur singly and are located in the mandible. Nonsyndromic bilateral dentigerous cysts (NSBDC) are rarely seen during childhood. The aim of this study was to determine the long-term effects of the marsupialization technique in growing children with NSBDC. Study design: Seven patients with NSBDC (4 female, 3 male) ranging in age from 7 to 9 years (mean 8.35 years) were involved in the study. All the individuals were treated by marsupialization. Space-maintaining appliances were applied during permanent teeth eruption. Intraoral photographs, and panoramic and periapical films were taken before surgery and during healing. Results: The NSBDC were successfully treated by the marsupialization technique and rapid healing period was observed in the growing patients, without any loss of permanent teeth. No recurrence was seen in the long-term follow-up period (3-10 years). Conclusion: Our clinical and radiological results revealed that using the marsupialization technique in children with NSBDC provided safe healing of permanent teeth around the dentigerous cysts in a short period. However, treatment planning and regular clinical follow-ups are necessary to ensure clinical success. © 2011 Akay et al, publisher and licensee Dove Medical Press Ltd.
