A late onset adult seizure due to intracerebral needle: case-based update.

BACKGROUND AND AIM: Late-onset seizure due to intracerebral needle is a rare entity. Most of them were clinically asymptomatic and rarely presented with seizure. Sewing needles are used in homicidal attempt in infancy or early childhood before the closure of the fontanels. Because of sociologic, politic, and scientific deficiencies subject remained untouched. We tried shedding some light on this ambiguous phenomenon. MATERIAL AND METHODS: We report a 54-year-old man who was admitted to our neurosurgery outpatient department with epilepsy due to a sewing needle located in the left frontal lobe of the brain and made extensive literature review. RESULT: Patient's physical and neurological examinations were completely normal. All biochemical and hematological tests were normal. Cranial tomography demonstrated a linear density at the left frontal lobe compatible with a sewing needle. Patient was followed-up with antiepileptic treatment with no seizure. Sixty cases from up-to-date literature and past cases were reviewed. Patients' ages differ from 4 days to 70 years. Our review showed four cases treated with antibiotics, 19 patients went to surgery, and others just followed-up with antiepileptic and other drugs. CONCLUSION: Literature needs an autopsy series for a more intimate estimation. Due to psychosocial and legitimacy problems, matter should be handled cautiously and law enforcement agencies must be informed. Follow-up with medication is the first line of treatment with asymptomatic patients. Treatment is dictated by clinic onset, physical examination, and patient consent.

Neuroprotective Effects of Milrinone on Experimental Acute Spinal Cord Injury: Rat Model.

OBJECTIVE: Spinal cord injury (SCI) disrupts nerve axons with devastating neurological consequences, but there is no effective clinical treatment. The secondary damage mechanism is a mainstay process, and it starts within a few minutes after trauma. We aim to investigate the neuroprotective effects of milrinone on the SCI model. MATERIALS AND METHODS: A total of 36 Wistar albino rats, each weighing 300-400 g, were randomly split into 4 groups that received different treatments: in group 1 (sham) (n = 9) control, only a laminectomy was performed; in group 2 (SCI) (n = 9), SCI was imitated after laminectomy; in group 3 (SCI + saline) (n = 9), physiological saline solution was injected intraperitoneally immediately after the SCI; and in group 4 (SCI + milrinone), milrinone was administered intraperitoneally on lateral decubitus position immediately after the SCI. Spinal cord contusion was established by the weight-drop technique after laminectomy. Neurological examination scores were recorded, and rats were killed 72 hours later. Serum and spinal cord tissue glutathione peroxidase, total antioxidant status, total oxidant status, 8-hydroxiguanosine, interleukin-6 and interleukin-10 levels, histopathological spinal cord damage score, and apoptotic index were examined and compared between groups. RESULTS: Neurological examination scores were significantly better in the milrinone-treated group compared with groups 2 and 3. SCI significantly increased serum and spinal cord tissue glutathione peroxidase, total oxidant status, 8-hydroxiguanosine, and interleukin-6 levels that were successfully reduced with milrinone treatment. Interleukin-10 and total antioxidant status levels decreased as a result of SCI increased with milrinone treatment. Increased histopathological spinal cord damage score and apoptotic index in groups 2 and 3 significantly decreased in group 4. CONCLUSIONS: Milrinone could reduce apoptosis and increase anti-inflammatory and antioxidative mediators, thus playing a protective role in secondary nerve injury after SCI in rats.

Ameliorating the effects of Adalimumab on rabbits with experimental cerebral vasospasm after subarachnoid hemorrhage.

BACKGROUND: Adalimumab (ADA), which is a new-generation recombinant human monoclonal antibody for tumor necrosis factor α (TNFα), has strong anti-inflammatory effects. The role of enhanced inflammation is well established for the development and progression of cerebral vasospasm. Investigated in the present study is the probable ameliorating and neuroprotective effects of ADA in rabbits using a cerebral vasospasm model with biochemical and histopathological methods. METHODS: Thirty male New-Zealand white rabbits were randomly divided into control, subarachnoid hemorrhage (SAH) only and SAH plus ADA treatment groups. SAH was established as a single cisterna magna autologous arterial blood injection. ADA treatment was started just after intracisternal blood injection and continued for 72 hours once a day. The animals were sacrificed 72 hours after the induction of SAH, serum and brainstem tissue obtained for investigations. RESULTS: Brainstem tissue and plasma levels of tumor necrosis factor-alpha and Interleukin-1ß, brainstem tissue Matrix metalloproteinase-9 levels increased after SAH and partly decreased after treatment. Plasma levels of brain-derived neurotrophic factor decreased after SAH and partly restored after treatment. ADA treatment significantly increased the mean cross-sectional area of the vasospastic basilar arteries, reduced the basilar artery wall thickness and also ameliorates enhanced endothelial apoptosis. CONCLUSION: Findings obtained in this study suggest that ADA is an effective neuroprotective agent for ameliorating cerebral vasospasm in experimental rabbit vasospasm.

Effect of Preoperative Uric Acid Level and Neutrophil / Lymphocyte Ratio on Preoperative and Postoperative Visual Analogue Pain Scores in Patients with Lumbar Disc Herniation: A Cross-Sectional Study.

AIM: To determine the relationship between the serum urate (SU) level, neutrophil / lymphocyte ratio (NLR), and pain severity using preoperative and postoperative visual analogue scale (VAS) scores in patients with lumbar disc herniation (LDH). MATERIAL AND METHODS: This single-center, cross-sectional study included 20 consecutive patients who were operated for LDH by the same surgeon. The patients'pre- and postoperative UA levels, NLRs, and intensity severity VAS scores were investigated. Preoperative magnetic resonance imaging (MRI) findings, serum UA levels, and neutrophil and lymphocyte counts were recorded. Pain severity was recorded preoperatively and at 6 months postoperatively. Effects of the preoperative SU levels and NLRs on the pre- and postoperative VAS scores were statistically assessed. RESULTS: Statistically significant positive correlation coefficients were determined between NLR and the preoperative and postoperative VAS scores. Negative correlation coefficients were found between the SU levels and preoperative VAS scores; in contrast, positive correlation coefficients were found between the SU levels and the postoperative VAS scores. CONCLUSION: Our results demonstrate the importance of not ignoring the serum UA level and NLR in pre- and postoperative pain in patients with LDH. Nevertheless, further extensive studies are warranted.

Comparison of the Effects of Contractubex Gel and Benzothiazole After Topical Application in an Experimental Model of Epidural Fibrosis in Rats.

BACKGROUND: Postoperative epidural adhesion is a frequent cause of failed back surgery syndrome, manifesting with back and leg pain or neurologic deficits. Development of preventive measures for epidural adhesion after laminectomy is critical to improve outcomes of lumbar surgery. We hypothesized that positive effects of topical application of Contractubex (CTX) gel and benzothiazole (BT) individually and in combination could aid in preventing epidural fibrosis in a rat laminectomy model. METHODS: Rats were randomly assigned to 2 control and 5 experimental groups (n = 8 for each group). The control(-) group received no surgery, whereas the control(+) group underwent laminectomy without any drug administration. In experimental groups, study agents applied to dura mater after laminectomy were 100mgCTX, 2.5%BT, 5%BT; 100mgCTXplus2.5%BT, and 100mgCTXplus5%BT. Laminectomy was performed at the L3 level for all rats. The extent of epidural fibrosis was assessed 4 weeks later macroscopically and histopathologically. Hepatic and renal toxicity of study drugs was assessed histopathologically. RESULTS: Topical CTX and BT individually and in combination reduced epidural fibrosis after laminectomy in rats. Although a meaningful decrease of epidural fibrosis with individual application of CTX and BT (2.5% or 5%) was obtained (P < 0.05), the effect of their combination was more pronounced without meaningful hepatic and renal toxicity (P < 0.05). CONCLUSIONS: Combined use of topical CTX and BT could be a potential therapy for epidural fibrosis. Further research with this agents for the prevention of epidural fibrosis is warranted.
