Is Indomethacin Harmful in Spinal Cord Injury Treatment? an Experimental Study
(Karger, 1999) Guven, MB; Cirak, B; Yuceer, N; Ozveren, F
This study was designed to analyze the effect of early indomethacin on the lipid peroxidation after spinal cord injury in rats. The use of anti-inflammatory drugs to affect delayed and secondary injury after trauma to the spinal cord has now become a matter of standard clinical practice. However, spinal cord injury remains an enormous clinical problem and research that may lead to improved treatment is to be encouraged and commended. Three experimental groups consisting of 40 rats each were formed. Using microsurgical technique, total laminectomy between T5 and T10 was performed. Spinal cord injury was achieved with an epidural aneurysm clip, and pharmacological treatment immediate after the injury was performed by injecting indomethacin intraperitoneally (i.p.) at a dose of 3 mg/kg to indomethacin-treated group. The three main groups were divided into subgroups of 8 rats each. It was planned to stop the biochemical reactions at a different time in each of these subgroups, by the application of liquid nitrogen to the spinal cord and paravertebral structures at the end of the 1st, 15th, 30th, 60th, and 90th minutes. All the spinal cords were removed and protected from further reactions by immersing in the liquid nitrogen tank. The lipid peroxidation levels were assessed by determining thiobarbituric acid reactive substances formation. The results of the study showed that the administration of 3 mg/kg indomethacin immediately after spinal cord injury induces lipid peroxidation to a significant degree (p < 0.05 one-way ANOVA and Tukey HSD tests) when compared to the saline-treated group. This result suggests that early posttraumatic indomethacin treatment may be harmful in spinal cord injury. Copyright (C) 2000 S. Karger AG, Basel.
Multiple Hydatid Cysts of the Brain: a Case Report and Review of the Literature
(Springer, 1998) Yuceer, N; Guven, MB; Yilmaz, H
Multiple hydatid cysts of the brain are uncommon and map be either primary or secondary. We report a 12-year-old child with multiple hydatid cysts of the brain occuring 1 year after surgical rupture of a primary large and infected cerebral hydatid cyst. Surgical removal of hydatid cysts was successfully performed. Albendazole (10 mg/kg twice daily for 12 weeks) was administered to the patient in the postoperative stage.
Tumours of the Lateral Ventricle. a Retrospective Review of 112 Cases Operated Upon 1970-1997
(Walter de Gruyter & Co, 1998) Gokalp, HZ; Yuceer, N; Arasil, E; Deda, H; Attar, A; Erdogan, A; Kanpolat, Y
Between the years 1970 and 1997, 112 patients with tumors of the lateral ventricle were operated on at the University of Ankara. School of Medicine, Department of Neurosurgery. Seventy-one patients (63.4 %) were male and 41 patients (36.6 %) female. Headache (35.7 %), nausea and vomiting (22.3 %) were the most common presenting complaints. Papilloedema (42.9 %), motor and sensory loss (25 %) were the most common findings at neurological examination. Complete tumor removal was accomplished in 38.4 % of the patients. Histopathologically the most commonly seen types of the tumor were ependymoma (25 %) and astrocytoma (21.4 %). Among the various approach, the anterior transcortical (53.6 %) and the posterior transcortical (16 %) were the most commonly used. Eleven patients were reoperated for tumor recurrence. After surgery, radiation therapy was also performed on fourty-two patients. The morbidity and mortality rates were considerably higher before 1976 when the use of microneurosurgical techniques was introduced. After this, our morbidity and mortality rates decreased dramatically The overall surgical mortality rate was 7.1 % before 1976; during the last 10 years (n:46), it was 6.5 %. In this report, our choice of operative approaches and the results will be discussed.
