Early diagnosis and early surgical resection can result in improvement in neurological deficits and in the quality of life of patients with a Intramedullary spinal cord metastasis.

General and regional anesthesia (spinal and epidural) can be performed successfully for lumbar disc surgery. The aim of this study was to assess the superiority of general anesthesia or epidural anesthesia techniques in lumbar laminectomy and discectomy. Sixty patients undergoing lumbar partial hemilaminectomy and discectomy were randomly divided into two groups receiving standardized general anesthesia (GA) or epidural anesthesia (EA). Demographically, both groups were similar. Surgical onset time (36.72 +/- 5.47 vs. 25.40 +/- 7.83 minutes) was longer in the EA group, but total anesthesia time (154.32 +/- 35.73 vs. 162.40 +/- 26.79 minutes) did not differ between the two groups. Surgical time (118.80 +/- 35.42 vs. 139.60 +/- 26.80 minutes) was longer in the GA group. The heart rate and mean arterial pressure values of the EA group measured 15, 20, and 25 minutes after local anesthetic administration to the epidural catheter were found to be lower than in the GA group measured after induction of general anesthesia. The frequency of bradycardia (EA vs. GA, 3 vs. 2), tachycardia (3 vs. 7), and hypotension (6 vs. 4) during anesthesia did not differ between the groups, but the occurrence of hypertension (1 vs. 7) was higher in the GA group. Blood loss was less in the EA group than in the GA group (180.40 +/- 70.38 vs. 288.60 +/- 112.51 mL). Postanesthesia care unit (PACU) heart rate and mean arterial pressure were higher in the GA group. Peak pain scores in PACU and postoperative 24 hours were higher in the GA group when compared with the EA group. Nausea was more common in the GA group both in PACU and 24 hours after surgery. There was no difference between the hospitalization duration of the groups. In conclusion, this study suggests that EA is an important alternative to GA during lumbar disc surgery.

A spinal tumor complicating pregnancy is a rare condition. A 25-year-old woman who became paraplegic during the 35th week of her second pregnancy presented during the postpartum period. She underwent two surgical interventions, and the cord compression caused by a T5 vertebral body hemangioma with laminar involvement and extradural extension was relieved. The occurrence of vertebral hemangiomas during pregnancy is discussed; the radiological features with special reference to magnetic resonance imaging are outlined; and cases from the literature are reviewed.

BackgroundHead trauma is one of the most important clinical issues that not only can be fatal and disabling, requiring long-term treatment and care, but also can cause heavy financial burden. Formation or distribution of free oxygen radicals should be decreased to enable fixing of poor neurological outcomes and to prevent neuronal damage secondary to ischemia after trauma. Coenzyme Q10 (CoQ10), a component of the mitochondrial electron transport chain, is a strong antioxidant that plays a role in membrane stabilization. In this study, the role of CoQ10 in the treatment of head trauma is researched by analyzing the histopathological and biochemical effects of CoQ10 administered after experimental traumatic brain injury in rats. A traumatic brain-injury model was created in all rats. Trauma was inflicted on rats by the free fall of an object of 450 g weight from a height of 70 cm on the frontoparietal midline onto a metal disc fixed between the coronal and the lambdoid sutures after a midline incision was carried out.ResultsIn the biochemical tests, tissue malondialdehyde (MDA) levels were significantly higher in the traumatic brain-injury group compared to the sham group (p < 0.05). Administration of CoQ10 after trauma was shown to be protective because it significantly lowered the increased MDA levels (p < 0.05). Comparing the superoxide dismutase (SOD) levels of the four groups, trauma + CoQ10 group had SOD levels ranging between those of sham group and traumatic brain-injury group, and no statistically significant increase was detected. Histopathological results showed a statistically significant difference between the CoQ10 and the other trauma-subjected groups with reference to vascular congestion, neuronal loss, nuclear pyknosis, nuclear hyperchromasia, cytoplasmic eosinophilia, and axonal edema (p < 0.05).ConclusionNeuronal degenerative findings and the secondary brain damage and ischemia caused by oxidative stress are decreased by CoQ10 use in rats with traumatic brain injury.

There is no consensus in the literature on the effects of the development of hydrocephalus on survival and disability after intracerebral haemorrhage (ICH) and the benefits of external ventricular drainage (EVD). In this open, prospective study, we investigated the clinical courses, radiological findings and outcome scores of 47 consecutive patients who were admitted to our clinic with spontaneous ICH. Hydrocephalus developed in 6 (12.8%) of the 47 patients, and EVD was applied in these 6 cases. In one of the 6 patients, the lesion was additionally excised due to the large cerebellar haematoma. Intraventricular haemorrhage was more common in patients developing hydrocephalus (83.3% vs. 29.3% in patients without hydrocephalus; p<0.05) and the lesions of all the patients were in the proximity of the ventricular system. Hospital mortality and functional outcome were not significantly different between patients with and without hydrocephalus. Our results shown that acute obstructive hydrocephalus should be anticipated if haematoma is near the ventricle or if it is opening to the ventricle. EVD is a life-saving and effective procedure that should be performed in patients who develop hydrocephalus following spontaneous intracerebral haemorrhage.

Neurocutaneous melanosis is an uncommon congenital disorder consisting of benign or malignant melanocytic tumors of the leptomeninges with large or numerous cutaneous congenital melanocytic nevi. The Dandy-Walker malformation occurs as an enlarged posterior fossa with high insertion of the tentorium, hypoplasia or aplasia of the cerebellar vermis, and cystic dilatation of the fourth ventricle. To our knowledge, the association of these two conditions has been reported only 14 times. In this article, we present a newborn patient with neurocutaneous melanosis associated with Dandy-Walker malformation, which was diagnosed by magnetic resonance imaging.

Spinal cord injury (SCI) results in rapid and significant oxidative stress. This study was aimed to investigate the possible beneficial effects of Ebselen in comparison with Methylprednisolone in experimental SCI. Thirty six Wistar albino rats (200-250 g) were divided in to six groups; A (control), B (only laminectomy), C (Trauma; laminectomy + spinal trauma), D (Placebo group; laminectomy + spinal trauma + serum physiologic), E (Methylprednisolone group; laminectomy + spinal trauma + Methylprednisolone treated), F (Ebselen group; laminectomy + spinal trauma + Ebselen treated), containing 6 rats each. Spinal cord injury (SCI) was performed by placement of an aneurysm clip, extradurally at the level of T11-12. After this application, group A, B and C were not treated with any drug. Group D received 1 ml serum physiologic. Group E received 30 mg/kg Methylprednisolone and, Group F received 10 mg/kg Ebselen intraperitoneally (i.p.). Rats were neurologically examined 24 h after trauma and spinal cord tissue samples had been harvested for both biochemical and histopathological evaluation. All rats were paraplegic after SCI except the ones in group A and B. Neurological scores were not different in traumatized rats than that of non-traumatized ones. SCI significantly increased spinal cord tissue malondialdehyde (MDA) and protein carbonyl (PC) levels and also decreased superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) enzyme activities compared to control. Methylprednisolone and Ebselen treatment decreased tissue MDA and PC levels and prevented inhibition of the enzymes SOD, GSH-Px and CAT in the tissues. However, the best results were obtained with Ebselen. In groups C and D, the neurons of the spinal cord tissue became extensively dark and degenerated with picnotic nuclei. The morphology of neurons in groups E and F were very well protected, but not as good as the control group. The number of neurons in the spinal cord tissues of the groups C and D were significantly less than the groups A, B, E and F. We concluded that the use of Ebselen treatment might have potential benefits in spinal cord tissue damage on clinical grounds.
