Transforaminal epidural steroid injection is one of the commonly employed modalities of treatment in managing nerve root pain. However, there have been no controlled prospective evaluations of epidural and nerve root contrast distribution patterns and other aspects of fluoroscopically directed lumbosacral transforaminal epidural steroid injections. ⋯ Lumbosacral transforaminal epidural injections, performed under fluoroscopic visualization, provide excellent nerve root filling and ventral epidural filling patterns. However, unrecognized intravascular needle placement with negative flashback or aspiration was noted in 5% of the procedures.

To discuss the diagnostic relevance and safety concerns of performing magnetic resonance imaging (MRI) in the presence of an implanted spinal cord stimulator (SCS). ⋯ The diagnostic value of MRI may outweigh the potential dangers of using this imaging modality when a patient with a neurostimulation device presents with a new-onset neurological deficit. Thorough informed consent and close physician monitoring of these patients during the MRI is imperative.

The concept of involving pediatric patients in medical decision-making, in both clinical and research anesthesia and surgical care, has support from specialists involved in pediatric care. Production pressure in the workplace creates conflict between ethical anesthesia practice - such as obtaining informed consent - and time efficiency. Specialized documentation of anesthesia consent may increase efficiency but could weaken the consent process. Concerns with cost containment have led to interventional quality improvement activities that may constitute research and therein require informed consent. This review discusses these three consent issues as they relate to anesthesia care. ⋯ Anesthesiologists have ethical obligations to involve children in the medical decision-making process as much as the child's capacity allows, and to place patient advocacy in the informed consent process above production pressures. While a specific and separate anesthesia informed consent form may be useful, it should not undermine the process of informed consent or relegate the consent process to non-physician personnel. The informed consent process for anesthesia care remains the province and responsibility of the individual anesthesiologist.

Although enthusiasm of intensivists has been raised during the last 2-3 years due to several successful clinical trials, severe sepsis and septic shock still have an increasing incidence with more or less unchanged mortality. Within the last 12 months, the progress in sepsis research covering definitions, epidemiology, pathophysiology, diagnosis, standard and adjunctive therapy, as well as experimental approaches is encouraging. In this review, state-of-the-art publications of 2003 are presented to elucidate the possible impact on clinical routine. ⋯ Scientific progress in areas of sepsis has been continuing throughout 2003, although the challenges are still enormous. The identification of more specific markers and new therapeutic approaches will hopefully improve the diagnosis, monitoring of therapy, and outcome in the septic patient.

Postherpetic neuralgia (PHN) remains a difficult pain problem for patients and physicians alike. This review describes the epidemiology and pathophysiology of PHN and discusses proposed mechanisms of pain generation and the various treatments currently available. Evidence is scant for the value of surgical and procedural interventions in general, although there are numerous small studies supporting the use of specific interventions such as nerve blocks, neurosurgical procedures and neuroaugmentation. ⋯ Interventions with low risk, such as TENS are appropriate. Although prevention of postherpetic neuralgia appears to be an appropriate strategy, there is little evidence to support the position that medical or interventional approaches (nerve blocks) will prevent PHN after a patient develops acute herpes zoster (HZ). Although antivirals are appropriate for acute HZ, and the use of neural blockade and sympathetic blockade may be helpful in reducing pain in selected patients with HZ, there is little evidence that these interventions will reduce the likelihood of developing PHN.
