Spinal anesthesia has been widely used as a safe and simple procedure. Most complications related with spinal anesthesia are self-limited and respond well to treatment. Nevertheless, neurological complications can be troubling with the use of anesthetics as well as the patients. Here, a case of neurological complication with aggravated pain and weakness of the lower extremities following spinal anesthesia is reported.

BACKGROUND: Epidural steroid injections (ESI) have been used widely for the treatment of back and radiating extremity pain. Although its effects on the metabolic and endocrine system have been studied, the effects following repeated injections remain to be determined. We studied the effects of three repeated caudal epidural injections of low dose triamcinolone. METHODS: The subjects were 10 elderly women with spinal stenosis. Caudal epidural injections were performed biweekly. Triamcinolone (20 mg), mixed with 15 ml of 0.25% lidocaine, was used as the ESI injectate. The procedures were performed with the patient in the prone position. Blood sampling was performed just before the first injection, and used as the baseline, and then just before each injection on the same day of the 2nd and 4th weeks, with the last samples taken 2 weeks after the third injection. RESULTS: The blood glucose concentrations showed no significant changes. The blood cortisol and ACTH concentrations were significantly decreased after the first injection, but there were no further decreases after each of the subsequent injections. The cortisol concentrations were maintained within the normal range. CONCLUSIONS: Caudal epidural injections, with low dose triamcinolone, suppressed the hypothalamus-pituitary-adrenal (HPA) axis, but no further suppression followed the subsequent repeated injections. Three consecutive caudal injections at 2 week intervals seems to be a safe procedure.

BACKGROUND AND OBJECTIVES: It is necessary to establish the most efficient diagnostic and therapeutic method for benign paroxysmal positional vertigo (BPPV), which is appropriate for Korean healthcare system. We aimed to evaluate current state of Korean clinician's diagnostic and therapeutic approaches for BPPV. MATERIALS AND METHODS: A 16-item survey was emailed to the members of dizziness department of Otology Research Interest Group in the Korean Otologic Society (n=68). 43 were returned and analyzed. RESULTS: All respondents (100%) used Dix-Hallpike test as a diagnostic tool for vertical canal-BPPV. Supine roll test was used for diagnosing lateral canal BPPV in nearly all the respondents (97.7%). Epley maneuver was chosen as otolith repositioning maneuver (ORM) for posterior canal BPPV in all respondents and barbecue rotation (BBQ) was used for treating lateral canal BPPV with geotropic nystagmus in 95.3% of respondents. Extreme variation was noted for therapeutic approach of lateral canal BPPV with ageotropic nystagmus BBQ, with 4 kinds of ORM and adjunctive measures to liberate otolith from cupula, while BBQ was again the most commonly used ORM (76.7%). CONCLUSION: The development of practical and efficient ORM for lateral canal BPPV with ageotropic nystagmus is necessary.
