Treatment of empty sella syndrome with ventriculoperitoneal shunt.

A symptomatic empty sella developed in a female patient undergoing bromocriptine therapy for microprolactinoma. Placement of a ventriculoperitoneal shunt dramatically improved the symptoms of headache and blurred vision. The post-operative imaging showed resolution of the empty sella.

Intramuscular electroporation with the pro-opiomelanocortin gene in rat adjuvant arthritis.

Endogenous opioid peptides have an essential role in the intrinsic modulation and control of inflammatory pain, which could be therapeutically useful. In this study, we established a muscular electroporation method for the gene transfer of pro-opiomelanocortin (POMC) in vivo and investigated its effect on inflammatory pain in a rat model of rheumatoid arthritis. The gene encoding human POMC was inserted into a modified pCMV plasmid, and 0-200 microg of the plasmid-POMC DNA construct was transferred into the tibialis anterior muscle of rats treated with complete Freund's adjuvant (CFA) with or without POMC gene transfer by the electroporation method.
