We rep.rt the first case of immediate-typ. hyp.rsensitivity caused by Emla. c ream. A 55-year-old woman, after using Emlacream, went on to develop.urticar ia. An op.n test was p.sitive to Emlacream. p.tch tests and p.ick tests were p.erformed with Emlacream, the comp.nents of Emlacream (lidocaine, p.ilocaine and castor oil) and other local anaesthetic s. The p.tch test with lidocaine and the p.ick test with Emlacream were both p.ositive. An intradermal test and subcutaneous administration of 3 anaesthetics t hat had negative p.tch tests and p.ick tests were p.rformed and well tolerated,a llowing their use. In the literature, anap.ylactic reactions to lidocaine inj.ct ions, delayed-typ. hyp.rsensitivity after lidocaine subcutaneous inj.ctions and contact dermatitis from Emlacream have all been described. This first case of contact urticaria from Emlacream was due to lidocaine and did not show any cr oss-reaction with other local anaesthetics.

Background and aims: Bacterial infections are common comp.ications in p.tients with acute p.ncreatitis, and translocation of bacteria from the intestinal lumen is p.obably the first step.in the p.thogenesis of these infections. As blood cultures in afebrile p.tients are usually negative, more sensitive methods to investigate this hyp.thesis in p.tients are needed. Our group.has recently develop.d a method to detect the p.esence of bacterial DNA in biological fluids, and we aimed to detect bacterial DNA in p.tients with acute p.ncreatitis, as molecular evidences of bacterial translocation. Methods: Samp.es of blood were obtained on three consecutive days within the first six days after admission. Bacterial DNA was detected using a p.lymerase chain reaction based method, and an automated DNA nucleotide sequencing p.ocess allowed identification of bacteria sp.cies. Results: Thirty one consecutively admitted p.tients with acute p.ncreatitis were studied. Bacterial DNA was detected in six p.tients (19.3% ), and the sequencing p.ocess allowed identification of Citrobacter freundii and p.eudomonas aeruginosa. In two p.tients the same bacteria detected at admission was detected 24 hours later (above 99.9% homology of nucleotide sequence). Basic clinical and biochemical characteristics were similar among p.tients with or without the p.esence of bacterial DNA. Conclusion: Detection of gram negative bacteria derived bacterial DNA in our series sup.orts the contention that bacterial translocation is a systemic p.ocess in ap.roximately 20% of p.tients with acute p.ncreatitis that does not seem to be related to the severity of the ep.sode or immediate develop.ent of

UVA1光疗法治疗脂质渐进性坏死

世界核心医学期刊文摘（皮肤病学分册） 2006年第5期2卷 28-29页

The p.imary c ause of collagen degeneration in necrobiosis lip.idica (NL) is p.op.sed to be immunologically mediated vascular disease. Ultraviolet (UV)A1 has been used successfully to treat scleroderma in which both vascular damage and collagen dysregulation also occur. We treated six p.tients with NL [(five women; mean age of 32 years (range 22-70) and mean disease duration of 2.9 years (range 6 months to 5 years)] with a high-outp.t ultraviolet (UV)A1 2-kW filtered metal halide source (Dr; Dermalight ultrA 1) having an emission sp.ctrum of 340-440 nm. All p.tients had NL on the shins, which had been unresp.nsive to p.tent top.cal corticosteroid therap. (n = 6) and had resp.nded minimally or not at all to TL-01UVB (n = 2), top.cal p.oralen p.us UVA(p.VA) soaking (n = 2) or oral p.VA(n = 1) therap.. p.tients received a variable number of total exp.sures (15-51), given 3-5 times weekly. NL resolved comp.etely in one p.tient; this p.tient had minimal imp.ovement after the first course of 16 exp.sures, but after a further 13 exp.sures, resolution occurred 6 months later. Two subj.cts obtained moderate imp.ovement in their overall disease severity after 15 and 24 exp.sures, while two had only minimal imp.ovement after 15 and 51 exp.sures. The remaining p.tient had no imp.ovement after 16 treatments. p.tients with the shortest disease duration had the greatest resp.nse. UVA1 therap. may be of benefit for the treatment of NL as an adj.vant therap. to top.cal corticosteroids or as a second-line alternative to other p.ototherap.es, and may have a sup.rior outcome in a p.op.rtion of p.tients.
