Background:Thoracolumbar fractures are among the most common types of damages caused to the spinal cord .Therefore, the aim of this study was the comparison of surgical or nonsurgical treatment outcomes in patients with thoracolumbar fracture with score 4 of the thoracolumbar injury classification and severity (TLICS)Methods:This study was clinical trial and double blind. Patients with thoracolumbar fracture with score 4 of TLICS entered at this research. We divided patients in 2 groups randomly (each group 25 patients) and then we followed patients for 1 year after start of treatment. We checked duration of bedridden and absence work, pain every 3 months for 1 year and radiography every 3 months for 1 year.Results:Pain in operative group was lower than nonoperative group (P = .02). Regional sagittal angles (RSA) in operative group was lower than nonoperative group in all time (P = .0001). Mean of time of return to work in operative group was lower than nonoperative group (P = .001).Conclusions:Pain and mean of time of return to work and RSA in operative group was lower than nonoperative group. The present data suggest the use of operative method in patients with thoracolumbar fracture with score 4 of TLICS.

Background:Electroconvulsive therapy (ECT) is one of the available and the most effective therapies for the treatment of resistant depression. Considering the crucial role of seizure duration on therapeutic response in patients treated with ECT, this study aimed to compare the effect of ketamine and sodium thiopental anesthesia during ECT for treatment of patients with drug-resistant major depression (DRMD).Materials and Methods:In a double-blind randomized clinical trial, 160 patients with DRMD were selected consequently and were assigned randomly into two groups including ketamine 0.8 mg/kg and sodium thiopental 1.5 mg/kg. The seizure duration, recovery time, and the side effects of anesthesia were evaluated after 1-h after anesthesia. Data of recovery time and complication collected in 2nd, 4th, 6th, and 8th ECT. Depression was assessed by Hamilton depression scale.Results:The results indicated that ketamine and sodium thiopental had a significant effect on the reduction of depression scores in patients with DRMD (P < 0.05). Complications such as a headache, nausea, pain at the injection site, short-term delirium, and long-term delirium were higher in ketamine group (P > 0.05). But ketamine was more effective in improvement of depression score and increasing systolic and diastolic blood pressure (P < 0.05). The mean of seizure duration showed a decreasing trend and was significant between two study groups (P < 0.05).Conclusion:Anesthesia induced by ketamine during ECT therapy increased blood pressure and seizure duration. Therefore, due to lower medical complication and attack rate of seizure, ketamine is an appropriate option for anesthesia with ECT in patients with DRMD.

Hip fracture is one of the important health problems of human societies. The aim of this study was to investigate the outcome of patients with this fracture using vitamin D3. This double-blind clinical trial was performed on 100 patients with hip fractures who referred to Valiasr Hospital. All specimens were evaluated for vitamin D3. Group A have had vitamin D3 in the normal range and received a dose of 50,000 vitamin D3 as blouse. Group B included individuals with hip fractures that did not have normal vitamin D3 levels. In this group, individuals received a dose of 50,000 units vitamin D3 in the form of muscular blouse, and then 50,000 units of vitamin D3 were given orally each week up to 12 weeks after surgery. After surgery, both groups were examined clinically and radiologically for ulcer and fracture healing. Moreover, mortality was checked 2 weeks after surgery and each month until healing. There was no significant difference in radiographic examination in the two groups in the term of adhesion and fracture union (P <0.05). The formation of the union in the clinical examination 4 and 8 weeks after treatment in two groups showed significant difference. The formation of union in clinical presentation 4 weeks and 8 weeks after treatment in two groups showed significant difference (P = 0.005; P = 0.036). The results showed that a group with low vitamin D, but with supplementation, had more fracture union after 4 and 8 weeks after starting treatment. Vitamin D supplementation could improve patients' condition 4 and 8 weeks after treatment.

The study aims to evaluate the efficacy of ondansetron in preventing post-spinal headache, considering the high prevalence of the headache in pregnant women and the common use of the adjuvants for prophylaxis against post-operative nausea and vomiting (PONV). This double-blind clinical trial included the 195 patients who were referred to Taleghani Hospital (in Arak, Iran) for cesarean section (C/S) under spinal anesthesia, and then the subjects were assigned to three equally sized groups using block randomization. Participants in the first, second, and control groups received 8 mg, 4 mg of ondansetron, and normal saline, respectively, 5 minutes before surgery. A final volume of 5 cc was prepared by adding normal saline. Participants were examined for headache one week after surgery, and then data analysis was performed using SPSS 20. The incidence of post-spinal headache was significantly higher in the placebo group than in the ondansetron 8-mg and 4-mg groups at 24 hours after surgery (P < 0.010). But, no significant difference was observed between two ondansetron groups (P ≤ 0.05). The overall incidence of the headache was generally lower in ondansetron 8-mg (26.66% vs. 33.68.05%) and 31.66% in ondansetron 4-mg (P < 0.001). Moreover, the PONV incidence was significantly higher in the placebo group than in the other two groups at 24 hours (P < 0.001). The hemodynamic variables were same in three groups. The ondansetron 8-mg dose can be effective to prevent headache after spinal anesthesia for C/S. Moreover, the ondansetron 8-mg and ondansetron 4-mg have same effect in control of PONV after spinal anesthesia for C/S.
