    Comparison of Melatonin and Ozone in the Prevention of Reperfusion Injury Following Unilateral Testicular Torsion in Rats
    (ELSEVIER SCIENCE INC, 2012) Ekici, Sinan; Ekici, A. Isin Dogan; Ozturk, Guler; Aksungar, Fehime Benli; Sinanoglu, Orhun; Turan, Guven; Luleci, Nurettin
    OBJECTIVE To compare the efficacy of ozone with melatonin, shown as the most powerful antioxidant in attenuation of testicular ischemia/reperfusion injury, in an experimental rat model of testicular torsion/detorsion. METHODS Twenty-four male Wistar rats were divided into 4 groups: sham-operated, torsion/detorsion, torsion/detorsion plus melatonin, and torsion/detorsion plus ozone. Melatonin (10 mg/kg) and ozone (4 mg/kg) were intraperitoneally injected daily beginning 15 minutes before detorsion for the following 7 days. At the seventh day, blood and tissue samples were obtained. Johnsen score, malondialdehyde, inhibin B, glutathione plasma total sulfhydryl group (RSH) levels, and total nitric oxide were studied. RESULTS Torsion/detorsion caused increase in tissue malondialdehyde and total nitric oxide along with a decrease in Johnsen score, tissue and plasma inhibin B, RSH, and glutathione levels. Melatonin prevented the rise in malondialdehyde and total nitric oxide levels and improved Johnsen score, tissue and plasma inhibin B, and tissue glutathione levels, along with a decrease in plasma RSH level. Ozone showed similar results except for the total nitric oxide level. Concomitantly, in contralateral testis, melatonin and ozone induced similar changes for Johnsen score, malondialdehyde, and inhibin B (not significant) and in glutathione (significant). Melatonin decreased the total nitric oxide level in both testes and ozone increased the same parameter. CONCLUSION On different pathways, ozone was comparable with melatonin in the amelioration of ischemia/reperfusion injury. Protective effects of ozone were associated with nitrous oxide. The potential for ozone as a treatment for torsion/detorsion therefore deserves to be further elucidated. UROLOGY 80: 899-906, 2012. (C) 2012 Elsevier Inc.

    Efficacy of pulsed radiofrequency treatment on the saphenous nerve in patients with chronic knee pain
    (IOS PRESS, 2011) Akbas, Mert; Luleci, Nurettin; Dere, Kamer; Luleci, Emel; Ozdemir, Ugur; Toman, Huseyin
    Background and objective: We studied the long-term efficacy of pulsed radiofrequency treatment (PRF) on the saphenous nerve in 115 patients with chronic knee pain. Materials and methods: 115 patients with chronic knee pain were investigated in a period of 22 months retrospectively. All patients had pulsed radiofrequency to the saphenous nerve. The mean age was 59 (range, 51-67). All patients were accessed with the visual analog scale (VAS) and WOMAC score pain at rest, pain on movement, and pain in flexion at 10th day, 3rd and 6th months post procedure. Results: All patients showed improvement in their VAS scores as well as in their WOMAC scores after ten day, three month, and 6 months (p = 0.001). No side effects were reported. Conclusion: PRF application to the saphenous nerve for eight minutes showed remarkable amount of patient satisfaction. Application of PRF for the second time could be recommended if it shows some benefit after the sixth month. But none of our patients needed a second application of PRF after six months period.

    Transsacrococcygeal approach to ganglion impar: radiofrequency application for the treatment of chronic intractable coccydynia
    (DOVE MEDICAL PRESS LTD, 2016) Adas, Cemil; Ozdemir, Ugur; Toman, Huseyin; Luleci, Nurettin; Luleci, Emel; Adas, Hilal
    Objective: Coccydynia is defined as pain in the coccygeal region. Among the many causes of coccydynia, the most common cause is trauma as a result of falling on the buttocks, repetitive microtrauma, or childbirth. Several methods are currently used for the treatment of coccydynia, including nonsteroidal anti-inflammatory drugs, intrarectal manipulation, epidural injections, ganglion impar blocks, and radiofrequency treatment (RFT). Wemm and Saberski used the transacrococcygeal methods to reduce tissue trauma. RFT is a percutaneous minimally invasive procedure. In this study, we aimed to assess the effect of the transsacrococcygeal approach on ganglion impar RFT in patients with chronic coccydynia. Methods: We retrospectively examined the data of 41 patients at the Department of Anesthesiology and Reanimation, Faculty of Medicine, Maltepe University (Pain Clinic), between January 1, 2010, and December 31, 2012. Results: The mean age of the patients was 46.68 +/- 11.00 years (range 28-67 [46] years). The average pain duration was 3.10 +/- 1.37 years. The difference between visual analog scale scores of the pre-and postprocedure was statistically significant. In the examinations carried out in the sixth month of the treatment, 90.2% of patients had a successful outcome, whereas treatment failed in 9.8% of patients. According to our patients' data, most of them had pain due to a trauma, were female, and overweight. Visual analog scale difference between preprocedure and early postprocedure, preprocedure and first month, preprocedure and sixth month were statistically significant (P= 0.001). Conclusion: Based on the lower pain scores and low complication rates after the operations, the results suggest that application of RFT on ganglion impar by the transsacrococcygeal approach is an effective and safe method for the treatment of chronic coccydynia. Patient selection, technique, and experience are the most important factors affecting the success of this method.
