An immunological study of a case of tinea capitis in an adult

We evaluated the immunological aspects of a case of tinea capitis in an adult. Tests revealed alteration of the T4/T8 lymphocyte ratio (T4 increase and T8 decrease) and a decrease in polymorphonuclear leukocyte activity.     

The population biology of tench, Tinea tinea (L.), in two gravel pit lakes

The populations of tench from two gravel pit lakes of contrasting habitat type were studied. The population density of tench from St Peter's Lake, which has abundant aquatic vegetation was 176 individuals ha⁻¹ (102.2 kg ha⁻¹) compared to 0.3 individuals ha⁻¹ (0.5 kg ha⁻¹) in the Main Lake which has very little aquatic vegetation. The results of ageing tench by scales, opercular bones and otoliths were compared; all three structures gave similar results up to 9 years of age, but thereafter there were difficulties in ageing using scales and care was needed in counting annuli. The oldest tench caught was 15 years old. Growth of male and female tench was similar and fitted the von Bertalanffy model; for female tench L_∞ = 573 mm, K =0.122 and for male tench L_∞ = 586 mm, K =0.114. Recruitment was variable and strong year classes occurred in years with warm summers.     

中国基层医疗机构手癣和足癣诊治现状调查

目的了解基层医生有关手癣、足癣的诊治现状,分析影响因素,制定有针对性的措施。方法通过网络平台对全国19个省市的基层医生进行问卷调查。结果共回收完整问卷729份。结果显示:①约20%的基层医生对手、足癣的发病因素方面存在认识不足,约50%的基层医生对受侵犯皮肤的组织定位存在误区。②基层医生对手、足癣鉴别诊断的重要性重视不够,真菌镜检设备使用率不足一半。③基层医生能正确选用外用抗真菌药,硝酸咪康唑乳膏使用率超过80%。④仍有10.70%的基层医生推荐使用外用糖皮质激素治疗手、足癣。结论基层医生在手、足癣的规范诊疗方面仍有待提高。

A study of dermatophytosis in South West of Iran (Ahwaz)

Two hundred and seventy nine patients suspected of having fungal lesions were examined. Skin scrapping, hair samples and nail clippings were collected from patients. Direct and culture examinations were performed for all samples. About 115 cases of examined subjects had dermatophytosis. Dermatophytosis occurred mainly in adults males (20–29 years). Tinea cruris (24.3%) was the most common type of dermatophytosis followed by tinea pedis (16.5%), tinea corporis (14.8%), tinea ungium (13%), tinea capitis (11.3%), tinea faciei (11.3%), tinea manuum (7%) and tinea barbae (1.7%). Trichophyton mentagrophytes was the most prevalent species followed by Epidermophyton floccosum.

脓癣的发病情况和病原菌变迁:上海地区19年的回顾性研究

目的了解近19年间上海地区脓癣的发病情况、病原菌及其变迁。方法选取头皮屑及头发真菌直接镜检阳性和(或)真菌培养为皮肤癣菌者,记录其临床表现、感染方式及动物接触史等。结果头癣患者1 009例,其中男性437例,女性572例;年龄20 d～93岁,平均10.44岁;脓癣114例(11.30%),其中男性44例,女性70例。年龄20 d～68岁,平均10.60岁,5～10岁最多见(45.61%),其次为5岁以下儿童(31.58%)。感染方式:发内型48例,发外型66例。真菌培养阳性的脓癣95例,其中犬小孢子菌29例(30.53%)、紫色毛癣菌21例(22.11%)、须癣毛癣菌19例(20.00%)、红色毛癣菌15例(15.79%)、断发毛癣菌7例(7.37%)、石膏样小孢子菌4例(4.21%)。脓癣的发病呈上升趋势,须癣毛癣菌脓癣尤为显著。结论上海地区脓癣主要发生于10岁以内儿童,犬小孢子菌是最常见的致病菌,发外型感染较发内型多见。     

足癣义诊患者临床分析及特比萘芬联合疗法疗效观察

目的分析西京医院皮肤科近3a来每年足癣义诊患者基本情况,并对口服特比萘芬片结合外用特比萘芬乳膏治疗足癣进行疗效分析。方法回顾性分析3a来每年夏天足癣义诊活动中就诊于西京医院皮肤科足癣患者情况。其中2007年义诊患者随机分为3组。I为单纯特比萘芬乳膏治疗组,外用特比萘芬乳膏2次/d×2周;Ⅱ为单纯口服特比萘芬片组,给予口服特比萘芬片（兰美抒片）250mg/d×1周;Ⅲ组给予口服特比萘芬,250mg/d×1周,联合外用特比萘芬乳膏,2次/d×2周。3组分别在患者治疗1个月后电话随访。结果3a足癣义诊周患者平均真菌阳性率为75.76%;采用特比萘芬联合疗法治疗的患者,有效率高达85.26%,复发率不足6%。结论特比萘芬联合疗法治疗足癣疗效肯定。     

趾间型足癣患者细菌菌种分布特征

目的了解趾间型足癣患者趾间和健康志愿者趾间细菌菌种分布特征。方法对37例经临床和真菌镜检确诊的趾间型足癣患者的趾间进行细菌培养,然后给予1%联苯苄唑霜1次/d外用治疗4周,在治疗后的第1、2、4周分别对趾间再进行细菌培养。33例健康志愿者作为对照。结果健康志愿者趾间细菌培养葡萄球菌属占92.5%,其中表皮葡萄球菌占32.5%,未分离到金黄色葡萄球菌。趾间型足癣患者细菌培养葡萄球菌属占74.4%,其中金黄色葡萄球菌占27.9%,表皮葡萄球菌仅占2.3%,还分离到化脓性链球菌、粪肠球菌、屎肠球菌、奇异变形杆菌、铜绿假单胞菌等。经过4周的外用联苯苄唑霜治疗,金黄色葡萄球菌消失,表皮葡萄球菌又成为优势菌（37.5%）。结论趾间型足癣患者趾间金黄色葡萄球菌的分离率明显高,此乃足癣继发细菌感染的主要致病菌,因此积极治疗足癣对预防足癣合并症有非常重要的意义。
