The high prevalence of persistent neck pain due to involvement of cervical facet joints has been described in controlled studies. Therapeutic interventions utilized in managing chronic neck pain of facet joint origin include intraarticular injections, medial branch nerve blocks, and neurolysis of medial branch nerves by means of radiofrequency. ⋯ Cervical medial branch blocks were an effective modality of treatment in managing chronic neck pain secondary to facet joint involvement confirmed by controlled, comparative local anesthetic blocks.

Influence of sensory and proprioceptive impairment on the development of phantom limb syndrome during regional anesthesia.
The relation between impairment of sensorimotor function and occurrence of phantom limb syndrome (PLS) during regional anesthesia has not been described. This study assessed the temporal relation between PLS and the progression of sensorimotor impairment during placement of a brachial plexus nerve block. ⋯ This study provides a better understanding of the determinants of PLS by showing that the final position of PLS is related both to the abolition of proprioception and the initial position of the anesthetized limb.

ReviewChronic prostatitis/chronic pelvic pain syndrome: is there a role for local drug infiltration therapy?
The clinical syndrome of chronic prostatitis ranges from well-defined chronic bacterial infections to poorly defined chronic pelvic pain syndrome (CPPS), previously referred to as "prostatodynia" or "abacterial prostatitis." Faced with the obscure nature of the disease, its protracted course, and the poor response to oral medication, urologists have considered alternative routes of drug administration. We review the indications and outcomes of local drug infiltration (intraprostatic antibiotic and zinc, intrasphincteric botulinum toxin A, pudendal nerve blocks) and discuss their potential use and benefit in the treatment of chronic prostatitis syndromes.

[Racemic bupivacaine, levobupi vacaine and ropivacaine in regional anesthesia for ophthalmology -- a comparative study].
Racemic bupivacaine, used in peribulbar anesthesia owing to its high potential to promote motor blockade, presents a smaller safety margin for cardiotoxicity in relation to ropivacaine and levobupivacaine. The objective of this study was to compare the degree of motor blockade and alteration of intraocular pressure (IOP) produced by racemic bupivacaine, levobupivacaine and ropivacaine in peribulbar block. ⋯ Considering the advanced age of most of these patients and the high concentrations of local anesthetics used in peribulbar blockade, the use of ropivacaine and levobupivacaine produces motor blockade as effective as racemic bupivacaine while minimising risks for cardiotoxicity.

To evaluate the effectiveness and safety of an orbital block using an ultrashort, wide-bore blunt metal cannula to inject local anesthetic agents into the anterior sub-Tenon's space. ⋯ Effective and predictable ocular anesthesia can be achieved using a blunt, ultrashort cannula for sub-Tenon's block. The technique greatly reduces the risks for globe perforation, muscle damage, and other serious complications.
