    (Korean Neurosurgical Soc, 2012) Tucer, Bulent; Ekici, Mehmet Ali; Demirel, Serkan; Basarslan, Seyit Kagan; Koc, Rahmi Kemal; Guclu, Bulent
    Objective : The aim of this prospective study was to demonstrate the influence of some factors on the prognosis of microvascular decompression in 37 patients with trigeminal neuralgia. Methods : The results of microvascular decompression (MVD) in 37 patients with trigeminal neuralgia were evaluated at 6 months after surgery and were compared with clinical and operative findings. Results : The sex of the patient, the patient's age at surgery, the side of the pain, and the duration of symptoms before surgery did not play any significant roles in prognosis. Also, the visual analogue scale (VAS) of the patient, the duration of each pain attack, and the frequency of pain over 24 hours did not play any significant roles in prognosis. In addition, intraoperative detection of the type of conflicting vessel, the degree of severity of conflict, and the location of the conflict around the circumference of the root did not play any roles in prognosis. The only factors affecting the prognosis in MVD surgery were intraoperative detection of the site of the conflict along the root and neuroradiological compression signs on preoperative magnetic resonance imaging (MRI)/magnetic resonance angiography (MRA). Conclusion : These findings demonstrated that if neurovascular compression is seen on preoperative MRI/MRA and/or compression is found intraoperative at the root entry zone, then the patient will most likely benefit from MVD surgery.

    Protective Effects of Intralipid and Caffeic Acid Phenyl Esther (CAPE) on Neurotoxicity Induced by Ethanol in Rats
    (Turkish Neurosurgical Soc, 2017) Basarslan, Seyit Kagan; Osun, Arif; Senol, Serkan; Korkmaz, Murat; Ozkan, Umit; Kaplan, Ibrahim
    AIM: Ethanol causes oxidative degradation of the mitochondria! genome in the brain. This effect could contribute to the development of brain injury in some alcoholic patients. We investigated the protective effect of caffeic acid phenyl esther (CAPE) and intralipid (IL) on oxidative stress and neurotoxicity induced by ethanol intake. MATERIAL and METHODS: The forty-eight rats were randomly divided into seven groups. Ethanol was administered for acute toxicity. IL and CAPE were administered immediately after ethanol intake. Total oxidant status (TOS), total antioxidant status (TAS), and oxidative status index (OSi) were evaluated and histologic examination of cerebellum and brain tissue with Hematoxylin-Eosin and immuno-histochemical dyes was performed. RESULTS: In the ethanol group, TAS levels were significantly lower than the other groups and this finding indicates that the toxic effect of ethanol reduces antioxidant levels. In the ethanol group, TOS levels were significantly higher than the other groups. These results showed that ethanol induced oxidative stress. IL treatment increased TAS levels, and CAPE decreased TOS levels against ethanol toxicity. There was correlation between TAS and TOS levels. Also, histopathologic results confirmed these biochemical results. CONCLUSION: CAPE and IL treatment could be effective course of therapy to enhance therapeutic efficacy and may provide a promising approach for the treatment of neurotoxicity and oxidative stress induced by ethanol in clinic.
