1999～2007年皮肤科门诊浅部真菌发病及镜检情况分析

目的了解广州地区1999～2007年间皮肤科门诊浅部真菌病发病的种类和构成比及流行病学特点。方法对临床拟诊为浅部真菌病者,取皮屑行10%KOH涂片进行真菌直接镜检。结果2002年后就诊人数及构成明显增加,近9a发病种类和构成没有明显变化。各种浅部真菌病中发病检出率占前3位的依次为体癣（34.3%）、手足癣（32.6%）、股癣（12.4%）。镜检阳性率排前3位的为马拉色菌毛囊炎74.9%、花斑糠疹55.5%、甲癣45.5%,总阳性率为34.3%。镜检阳性率受病种、性别、年龄、取材部位、疑似鉴别病例数量等因素影响。结论就诊人数与检出率呈逐年增加的趋势,1999～2007年间广州地区浅部真菌发病的种类和构成比无明显变化,目前直接镜检法在临床上仍不失为经济、简便易行的真菌学检查方法。

Analysis of superficial mycoses and pathogenic fungi for patients during the period from 1999 to 2007 in dermatology clinic in Guangzhou

Objective To investigate the variety and constitute of superficial mycoses,as well as epidemiological character in outpatient clinic in Guangzhou during the period from 1999 to 2007. Methods Microscopic examination was used to suspected patients of superficial mycosis. Results There was no obvious change in variety and constitute of pathogenic fungi from 1999 to 2007, though the visiting number and constitute increased evidently since 2002. The incidence rate on the top list was ： tinea corporis （ 34.3% ）, tinea pedis and tinea manus （32.6%） ,tinea inguinalis （12.4%）. The positive rate under microscopy was pityrosporum folliculitis （74.9%） ,tinea versieolor （55.5%） ,and tinea unguium （45.5%） ,with the overall positive rate of 34.3% ,which is influenced by entity, sex, age, place where we draw from, and the number of suspected eases. Conclusion The visiting number and detection rate showed a gradually increasing tendency. There was no obvious change in variety and constitute of pathogenic fungi from 1999 to 2007. Direct microscopic examination is an economic and convenient method for diagnosis at present.
