This study is a parasitological and clinical study on human scabies. This study was carried out on 100 patients attending the Dermatology Outpatient Clinic at Ain Shams University Hospitals, including 54 males and 46 females. All patients were subjected to detailed history taking, complete dermatological examination including Skin Scraping Test and Burrow Ink Test. Younger patients attended the dermatology clinic earlier than older patients, who usually delayed their visits until complications occurred. Scratching, erythematous papules and secondary infected lesions were the commonest lesions. The hands, wrist and external genitalia were the most frequently affected sites while the feet, ankles, knees and back were the least affected. Burrows could only be detected in 40% of patients. The most frequent sites were the web spaces, external genitalia, and finger sides. Burrow Ink Test was positive among 85% of patients with burrows while mites could be identified by Skin Scraping Test in 55% of patients. The most frequent clinical manifestations in the parasitologically positive patients were itching, burrows, and papules, and the most frequent sites were the web spaces, and the finger sides. Multiple sites affection was the characteristic feature among the preschool age children who represented 14% of cases.
本研究是一项关于人类疥疮的寄生虫学和临床研究。该研究针对艾因·沙姆斯大学医院皮肤科门诊的100名患者展开，其中男性54名，女性46名。所有患者均接受了详细的病史采集、包括皮肤刮擦试验和隧道墨汁试验在内的全面皮肤科检查。较年轻的患者比年长的患者更早到皮肤科就诊，年长患者通常会推迟就诊，直到出现并发症。搔抓、红斑丘疹和继发性感染性皮损是最常见的皮损。手部、手腕和外生殖器是最常受累的部位，而足部、脚踝、膝盖和背部受累最少。仅40%的患者能检测到隧道。最常见的部位是指蹼间隙、外生殖器和手指侧面。85%有隧道的患者隧道墨汁试验呈阳性，而55%的患者通过皮肤刮擦试验能识别出疥螨。寄生虫学检查呈阳性的患者中最常见的临床表现是瘙痒、隧道和丘疹，最常见的部位是指蹼间隙和手指侧面。多部位受累是占病例14%的学龄前儿童的特征性表现。
