Ultrasound and nerve stimulator guidance lumbar transforaminal epidural block for the treatment of patients with lumbosacral radicular pain.

Transforaminal epidural block (TEB) is a widely accepted technique and minimally invasive procedure for the treatment of lumbosacral radicular pain. This study aimed to evaluate the accuracy, efficacy, and safety of ultrasound and nerve stimulator guidance lumbar transforaminal epidural block (UNTEB) for the patients with unilateral lower lumbar radicular pain. The accuracy of this method was evaluated by fluoroscopy. Using UNTEB via axial and the in-plane approach technique was performed in 42 segments of 25 patients who presented with lumbosacral radicular pain to lower extremities. The contrast medium was injected to evaluate the needle tip at the intervertebral foramen under fluoroscopic guidance. The numerical rating scale was used to assess pain before and after treatment. The success ratio of UNTEB in L3/L4 level was 100%, in L4/L5 was 95.4% and in L5/S1 was 100%. The numerical rating scale (NRS) for lumbosacral radicular pain improved from a mean from 7.8 to 2.8 1 day after procedure (p = 0.01) and from a mean from 7.8 to 2.4 1 week after UNTEB (p = 0.01). None of our subjects experienced any complications during and after the procedure. UNTEB with fluoroscopic validation is an accurate, effective, and safe method for short-term pain relief of the patients with unilateral lumbosacral radicular pain.

Comparing the Severity of Injury and Trauma Pattern between Scooter and Street Motorcycle Riders; a Prospective Cohort Study.

INTRODUCTION: The popularity of motorcycle riding in Iran is increasing. However, there is a lack of information about the safety of different motorcycle types. This study aimed to compare the severity of injury and trauma pattern between scooter (vespa) and street (standard) motorcycle riders. METHOD: In a prospective cohort study, a comparison of demographics, injury severity, trauma pattern, and clinical characteristics between 324 riders (162 Vespa and 162 standard motorcycles) admitted to emergency departments was undertaken. The risk factors associated with severe injuries in the two groups were also determined. An emergency medicine specialist determined the severity of trauma based on the abbreviated injury scale (AIS). RESULTS: The Odds Ratio (OR) of severe injuries was significantly higher in the standard motorcycle riders' group (OR: 3.09; 95% CI: 1.9-4.21; p: 0.013). The frequency of lower extremity fractures was significantly lower in the Vespa group (OR: 4.11; 95% CI: 2.01-6.25; p = 0.012). The frequency of admission to the intensive care unit was significantly higher in the standard motorbike riders' group (OR: 1.64; 95% CI: 1.11-2.51; p = 0.033). The multivariate analysis indicated that motorcycle type, the speed at the time of the accident, use of helmet, and age of riders are the most important predictors of trauma severity in riders (p<0.05). CONCLUSION: The pattern of injury varies between standard and Vespa motorcycles. The standard motorcycle riders were prone to a higher risk of adverse outcomes such as severe injuries. Due to the particular structure of scooters, the rate of lower limb injuries was significantly lower than standard motorcycles.

Repair of Ebstein anomaly: early and mid-term results.

BACKGROUND: Ebstein anomaly is the downward displacement and adherence of dysplastic septal and posterior tricuspid leaflets into the right ventricle, thereby dividing the ventricle into a so-called atrialized chamber and a functionally reduced right ventricle. We evaluated the early and mid-term results of primary repair of Ebstein anomaly in adult patients. METHODS: Eight consecutive patients undergoing repair of Ebstein anomaly with Danielson technique at Imam Khomeini Medical Center, Tehran, Iran from January 1997 through July 2004 were evaluated. Functional and echocardiographic parameters were studied both preoperatively and postoperatively, as well as demographic status and adverse events. RESULTS: Hospital mortality occurred in one patient because of right ventricular failure. The average follow-up period was 5.3 +/- 3.4 years (median: 3.8 years). The actuarial survival rate was 85.7 +/- 4.8% at 7 years. During the follow-up, six patients were in New York Heart Association functional class I, and one patient was in class II. None of the patients required reoperation related to their Ebstein repair. One patient demonstrated atrioventricular dissociation perioperatively; however, only one patient required permanent pacemaker insertion later. One patient had minimal (1+) regurgitation, with the jet localized along the anterior part of the ventricular septum. Two patients had residual tricuspid valve insufficiency (2+) on echocardiography. CONCLUSION: Ebstein repair has a good functional and hemodynamic outcome in adult patients.
