Objective:Burr-hole irrigation and burr-hole drainage without irrigation are the most popular methods for treatment of chronic subdural haematoma. It is not well known if irrigation is necessary or which method has a higher recurrence rate. We compared the recurrence rates of those two methods.Materials and Methods:Forty-two patients were treated by burr-hole irrigation (irrigation group), whereas 38 patients were treated by burr-hole drainage (drainage group). Recurrence rate and its relation with sex, age, haematoma localization and aetiology were investigated in both groups.Results:There was no significant difference between recurrence rates of the two groups. There was also no correlation between recurrence rate and age, sex, haematoma localization, or aetiology.Conclusions:There was no significant difference between recurrence rates of the two groups. Since the burr-hole drainage method is simpler to carry out, its use may be preferable.

The aim of this experimental study was to investigate the possible protective effects of dantrolene on traumatic spinal cord injury (SCI). Twenty-four New Zealand rabbits were divided into three groups: Sham (no drug or operation, n = 8), Control (SCI + 1 mL saline intraperitoneally (i.p.), n = 8), and DNT (SCI + 10 mg/kg dantrolene in 1 mL, i.p., n = 8). Laminectomy was performed at T10 and balloon catheter was applied extradurally. Four and 24 h after surgery, rabbits were evaluated according to the Tarlov scoring system. Blood, cerebrospinal fluid and tissue sample from spinal cord were taken for measurements of antioxidant status or detection of apoptosis. After 4 h SCI, all animals in control or DNT-treated groups became paraparesic. Significant improvement was observed in DNT-treated group, 24 h after SCI, with respect to control. Traumatic SCI led to an increase in the lipid peroxidation and a decrease in enzymic or non-enzymic endogenous antioxidative defense systems, and increase in apoptotic cell numbers. DNT treatment prevented lipid peroxidation and augmented endogenous enzymic or non-enzymic antioxidative defense systems. Again, DNT treatment significantly decreased the apoptotic cell number induced by SCI. In conclusion, experimental results observed in this study suggest that treatment with dantrolene possess potential benefits for traumatic SCI.

Background: Breast pain is one of the leading complaints that ends up with referral to breast surgery clinics. The purpose of the present study was to investigate the factors that cause mastalgia, and its relation with benign or malignant breast disease. Methods: The study was performed in 700 patients. Data obtained from surveys, and imaging findings were prospectively recorded, and analyzed. Results: The mean age was 45.20 ± 10.78 years. The mastalgia group included 500 cases; the asymptomatic group comprised 200 individuals. Stressful lifestyle, caffeine consumption, and smoking were associated with mastalgia (p < 0.05). Rates of women who had breast fed 3 times or more were higher in the mastalgia group (p < 0.05). Increased breast density, and breast imaging-reporting and data system (BI-RADS) 2 mammography findings were related with mastalgia (p < 0.05). Cysts and fibroadenomas were more common in the mastalgia group (p < 0.05). The incidence of a past history of malignant breast disease was significantly higher in the mastalgia group (p < 0.05). Conclusions: Stress, caffeine, smoking, lactation frequency, and benign disorders were factors detected to be related with mastalgia. Although a significant relation between mastalgia and malignant breast disease was detected in our study, more controlled studies are still required to investigate this issue further.

The purpose of this study was to investigate and to compare the effects of microsuturing to that of tissue adhesives (Tisseel) on the healing of anastomosing peripheral nerve incisions. Forty-five Wistar-Albino rats were placed in special cages and separated into three groups (n = 15). In the control group, biliteral sciatic nerves were explored but no incision was made. In the first experimental group, bilateral sciatic nerves were incised and end-to-end anastomosing was performed by microsuturing the epineurium. In the second experimental group, tissue adhesive (Tisseel) was used alone in anastomosing the sciatic nerve cuts. Assessments of the healing processes were demonstrated by 1.electromyography (EMG), 2. measuring the electrical responses of the anastomosed nerves after electrical stimuli, 3. histopathological examination. Statistical analysis of the EMG findings showed that the Tisseel group was the closest in the healing process to the control group. After applying electrical stimuli to the dissected nerves, the resistance value of the Tisseel group was nearest to those of the control group. The histopathological examinations showed highly degenerative nerve bundles and prominent foreign body granuloma at the anastomosed sites of the microsutured group. The granulomatous inflammation was observed to be much less in the Tisseel group. We conclude that the healing effect of Tisseel was found to be superior to that of microsuturing as demonstrated by the findings of EMG, electrical responses of the anastomosed nerves, and histopathological examination.

The aim of this experimental study was to investigate the possible protective effect of dexmedetomidine (DEX) on traumatic spinal cord injury (SCI). Twentytwo New Zealand rabbits were divided into three groups: sham (no drug or operation, n = 6), Control [SCI ? single dose of 1 mL saline intraperitoneally (i.p), after trauma; n = 8] and DEX (SCI ? 1 lg/kg dexmedetomidine in 1 mL, i.p, after trauma, n = 8). Laminectomy was performed at T10 and balloon angioplasty catheter was applied extradurally. Four and 24 h after surgery, rabbits were evaluated by an independent observer according to the Tarlov scoring system. Blood, cerebrospinal fluid (CSF), tissue samples from spinal cord were taken for biochemical and histopathological evaluations. After 4 h of SCI, all animals in control or DEX treated groups became paraparesic. On the other hand, 24 h after SCI, partial improvements were observed in both control and DEX treated groups. Traumatic SCI leads to increase in the lipid peroxidation and decreases enzymatic or nonenzymatic endogenous antioxidative defense systems. Again, SCI leads to apoptosis in spinal cord. DEX treatment slightly prevented lipid peroxidation and augmented endogenous antioxidative defense systems in CSF or spinal cord tissue, but failed to prevent apoptosis or neurodeficit after traumatic SCI. Therefore, it could be suggested that treatment with dexmedetomidine does not produce beneficial results in SCI.
