Published: October 1991

Epidural empyema is a rare complication of elective spinal surgery. Four such cases are described. The clinical features of this postoperative complication were surprisingly vague and misleading. Fever was uncommon. Local inflammatory signs or rapid neurologic deterioration were absent. Computerized tomography proved useful in diagnosis and follow-up. Unlike spontaneous spinal epidural abscess, postoperative spinal epidural empyema had a benign course. Causative bacteria were miscellaneous. Surgical evacuation of the purulent collection and appropriate antibiotic therapy resulted in cure in all cases.

Background: Optimising a mother's quality of recovery following caesarean delivery is of paramount importance as it facilitates maternal care of the newborn and affects physical, psychological and emotional well being. Intrathecal morphine (ITM) reduces postoperative pain and may improve quality of recovery: however its widespread use is limited.

Objective: To assess the effects of implementing ITM for caesarean delivery on postoperative quality of recovery.

Labor analgesia is increasingly widespread throughout the world with a rate ranging from 10 to 60%. The benefits regarding clinical and non-clinical maternal-fetal outcomes are currently discussed in international scientific literature. Even stage of labor needs a different and appropriate approach to control the pain; however, different techniques are reported in literature.

Millions of patients and their caretakers live and deal with the devastating consequences of spinal cord injury (SCI) worldwide. Despite outstanding advances in the field to both understand and tackle these pathologies, a cure for SCI patients, with their peculiar characteristics, is still a mirage. One of the most promising therapeutic strategies to date for these patients involves the use of epidural electrical stimulation.

The efficacy of epidural blood patch (EBP) is highly variable, and often, clinicians are unable to identify the underlying reasons for treatment failure. A 36-year-old parturient underwent a "blind" epidural blood patch (EBP) without image guidance but failed to obtain relief from a postural headache related to the labor epidural. During the second EBP, an intact plica mediana dorsalis (PMD) was visualized in the anterior-posterior fluoroscopic view after injection of contrast, and autologous blood was injected on both sides of the PMD, leading to the complete resolution of headache symptoms.

Purpose: Spinal cord stimulation (SCS) is pivotal in treating chronic intractable pain. To elucidate the mechanism of action among conventional and current novel types of SCSs, a stable and reliable electrophysiology model in the consensus animals to mimic human SCS treatment is essential. We have recently developed a new in vivo implantable pulsed-ultrahigh-frequency (pUHF) SCS platform for conducting behavioral and electrophysiological studies in rats.
