Transient Hypokalemic Quadriplegia After a Lumbar Transforaminal Epidural Dexamethasone Injection: A Case Report.
A 30-year-old man with no significant medical history presented with hypokalemic quadriplegia 4 hours after he received a lumbar transforaminal epidural steroid injection (ESI) containing dexamethasone and lidocaine. A comprehensive workup ruled out acquired and hereditary causes of hypokalemic paralysis. Symptoms gradually resolved within hours after potassium restoration with no residual neurologic deficits. ⋯ To our knowledge, there have been no case reports of paralysis after ESI with dexamethasone, a nonparticulate steroid. This transient paralysis is possibly caused by the effects of glucocorticoids on Na-K channels and insulin resistance resulting in hyperglycemia and subsequent hypokalemia. We reviewed the differential diagnosis of transient paralysis after epidural steroid injection in this report.

Low back pain (LBP) patients show reorganized trunk muscle activity but if similar changes are manifest in recurrent LBP (R-LBP) patients during asymptomatic periods remains unknown. In 26 healthy and 27 currently asymptomatic R-LBP participants electromyographic activity (EMG) was recorded from trunk and gluteal muscles during series of stepping up and down on a step bench before and during experimentally intramuscular induced unilateral and bilateral LBP. Pain intensity was assessed using numeric rating scale (NRS) scores. ⋯ In both groups, bilateral compared with unilateral experimental NRS scores were higher (P < .001) and patients compared with controls reported higher NRS scores during both pain conditions (P < .04). In patients, unilateral pain decreased ΔRMS-EMG in the Iliocostalis muscle and bilateral pain decreased ΔRMS-EMG in all back and gluteal muscles during step tasks (P < .05) compared with controls. In controls, bilateral versus unilateral experimental pain induced increased step task duration and trunk RMS-EMG whereas both pain conditions decreased step task duration and trunk RMS-EMG in R-LBP patients compared with controls (P < .05).

We compared the results of manual therapy combined with steroid injection with single steroid injection in the treatment of persistent coccydynia. ⋯ Manual therapy combined with steroid injection would be an alternative method in case of persistent coccydynia. It is a safe and easy option before surgical treatment.

Inflammatory back pain (IBP) is the earliest symptom of axial and other forms of spondyloarthritis (SpA). However, there are no published data on prevalence of IBP among patients suffering from chronic low back pain (CLBP) in Bangladesh. In this study, we estimated the prevalence of IBP and the subtypes of SpA in a tertiary hospital in Bangladesh. ⋯ Inflammatory back pain is common among patients presenting with CLBP. The commonest cause of IBP is AS, followed by PsA and nr-axSpA.
