Either conservative or surgical methods can be performed comfortably for adolescent lumbar disc herniations. We proposed surgical treatment for patients with incapacitating persistent low back pain or radicular pain that lasted more than 6 weeks, despite rest and medication. We also pursued the development of neurological deficits, including recurrent pain that disturbed routine life activities.

PURPOSE:To evaluate the central nervous system toxicity of cisplatin and neuroprotective effect of selenium. METHODS:Twenty-one male Wistar albino rats were divided into three groups: control (C), cisplatin (CS), cisplatin and selenium (CSE, n=7 in each group). Cisplatin (12 mg/kg/day, i.p.) was administered to CS and CSE groups for three days. Furthermore, CSE group received 3mg/kg/day (twice-a-day as 1.5 mg/kg) selenium via oral gavage five days before cisplatin injection and continued for 11 consecutive days. The same volumes of saline were administered to C group intraperitoneally and orally at same time. RESULTS:Heterochromatic and vacuolated neurons and dilated capillary vessels in the brain were observed in the histochemical examinations of cisplatin treated group. Rats that were given a dose of 3mg/kg/day selenium decreased the cisplatin induced histopathological changes in the brain, indicating a protective effect. In addition, cytoplasmic staining of the cell for bcl-2, both cytoplasmic and nuclear staining for bax were determined to be positive in the all groups. Bax positive cells were increased in the CS group compared to C group, in contrast to decreased bcl-2 positivity.CONCLUSION: Selenium limited apototic activity and histological changes due to the cisplatin related central neurotoxicity.

After strabismus surgery on the horizontal recti, there are some alterations in the retrobulbar blood flow with a significant difference between pre- and postoperative blood flow velocities after single and double rectus surgery. The clinical significance of these results needs to be determined because CDI may be a useful tool in the investigation of hemodynamic alterations after anterior segment interventions that may cause anterior segment ischemia.
