What stands in the way of treating palmar hyperhidrosis as effectively as axillary hyperhidrosis with botulinum toxin type A. (3/5)

Botulinum Toxin type A (BTX-A) has revolutionized the treatment of focal hyperhidrosis (HH) in recent years and has dramatically reduced the invasive surgical techniques that have been performed in the past to control severe focal HH unresponsive to topical therapies. Whereas BTX-A injections are easily performed to control axillary HH with little or no analgesia, pain management is a must during the injection of palmar and plantar HH with BTX-A because of the intense pain generated with the 30 to 40 needle punctures needed on each hand or foot through the densely innervated skin present in those areas. For that reason, many physicians who contentedly treat axillary HH with BTX-A injections, refuse to do so for palmar and plantar HH. Although pain is the major stumbling block deterring patients and physicians from choosing this treatment option, it is not the only one. Many other factors may play a role in deciding whether or not to treat palmar and plantar HH with BTX-A injections. This article reviews these factors and presents some personal data from patients who have already been treated with BTX-A injections on the palms and soles and who came back once or more for repeat treatments when the effect of BTX-A started to fade away. "Jet Anesthesia" was the pain management method used in this group.  (+info)

Local cryoanalgesia is effective for tail-tip biopsy in mice. (5/5)

Tail-tip biopsy for genotyping of genetically modified mice older than 21 d typically is performed by using isoflurane anesthesia. Isoflurane-induced changes in behavior and metabolism can result in unexpected complications and death. We investigated whether cryoanalgesia by using ethylene chloride spray would be an effective local anesthetic for tail-tip biopsies in mice. C57BL/6J mice were allocated randomly into 4 groups (n = 10 each) to receive isoflurane anesthesia with tail biopsy, ethylene chloride spray on the tip of the tail before biopsy, ethylene chloride spray without biopsy, or no treatment. Blood glucose was measured periodically in both groups undergoing tail biopsy, and the tail-pinch assay was performed in all mice that received ethylene chloride spray. Body weight, water, and food intake were measured daily for 2 wk. In both groups undergoing tail biopsy, blood glucose levels at 15 min were significantly higher than those after 2 min. This elevation was greater and more prolonged after 30 min in mice that received isoflurane compared with ethylene chloride spray. Tail-pinch latency at 20 min was greater than that after 2 min in all mice that received ethylene chloride spray. All mice gained weight, and there was no difference in food and water intake among groups. We conclude that ethylene chloride spray is an effective local anesthetic and a valuable alternative to isoflurane.  (+info)
