Cutaneous onchocerciasis in republic of Yemen (10 cases reported) Mohammed Abdol-Quader Almoallimi. Dermato-venereo Andrology Althawra Teaching Hospital Department of Dermatology Sanaa Unev. Faculty of Medicine and Health Sciences, Yemen Onchocerciasis is a leading cause of blindness in the world. The infection is endemic anions individuals in equatorial Africa Latin America, residing or working within a few kilometers of freely flowing waterways, wherein breed the intermediate hosts of onchocerca volvulus, the black files of the genus simulium. Within 6-7 days of biting an infected host, the files are capable of transmitting infected larvae to other individuals, who subsequently demonstrate signs of infection after 3-15 months. Objective: The objective of the study was to study the SAWDA cutaneous onchocerciasis in Yemeni men. Methods: Ten male Yemeni farmers between the ages 20-30 years old presented with prurigenous papulo-erythematous skin eruption unilateral to the Lt. Or Rt. lower limb of one year duration, with or without femoral or inguinal lymph node enlargement. There were no ocular manifestations and subcutaneous nodules (onchocercoma). Pre-admission skin scraping was positive in one case and the histopathological picture were not specific. Results: The clinical data and the detection of the larva under the microscope showed that the ten cases were cutaneous onchocerciasis. Conclusion: The local name of cutaneous onchocerciasis in Yemen is SAWDA (black or dark colour skin). This disease is quite common in some areas along waterways extending from WAD1 ATAMAT SAREA IN ALMAHWEET, WADI SORDOD IN HARAZ and WAD1 REMAA (YAADAR) in lower WESAB. The infection was sporadic. Control of the black files, health education, medical treatment with IVERMECTIN will restrict the Incidence of this disease.

agent were the larvae of some species of WOHLFAHRTIA and CHRYSOMYIA flies that penetrated the normal skin and were removed by forceps. Conclusion: Cutaneous and genito-urinary myiasis are rare in Republic of Yemen and these three cases reported by me first. Health education and control of the flies restrict the incidence of this disease.
FC066 Toxocara infection and cutaneous diseases. A case-control study Ph. Humbert’, M. Niezhorala’, R. Salembier*, F. Aubin’, Th. Barale3, S. Buchet ’ , C. Tessier-Cotte*. ‘Department of Dermatology; 2Department 3Department of Parasitology, Besangon Cedex, France
Human toxocariasis is one of the most common zoonotic helminthiasis. The recent development of sensitive and specific diagnosis laboratory tests have led to identify a large spectrum of diseases, including cutaneous diseases, induced by Toxocara infection. The purpose of our study was to assess the risk of having a positive Toxocara ELISA test in patients with different cutaneous symptoms. The diagnosis of toxocariasis was based on an ELISA test which was performed in 653 patients suffering from different skin conditions during a prospective case-control study. The excess of risk (adjusted odds ratio) of having a positive result to Toxocara ELISA was statistically significant for the 134 patients with urticaria (whatever the clinical presentation) and for the 22 patients with prurigo compared to the control group (249 patients). No statistical excess of risk was observed for patients with atopic dermatitis, or pruritus, or non atopic eczema. The authors conclude that patients suffering from urticaria or prurigo should be tested for Toxocara infection. Whether these patients should be treated with anithelminthic drugs remains to be determined in further studies.

Myiasis is a condition resulting from invasion of tissues of man or animals by larval stages of flies. Objective: The objective was to study cutaneous and genitourinary myiasis in Republic of Yemen. Methods: Two female Yemeni patients 12 and 30 years old presented with urethro-vaginal discharge and they saw some brownish blackish like worms in their urine. A male Yemeni farmer 25 years old had funmcle like skin lesion in the upper ft; high with severe stabbing pain. The duration varied from 4~0 8 months. The larvae were detected in the urine and in the skin lesion. Swab from the discharge was not specific. Results: The clinical data and detection of the larvae showed the two female cases were genito urinary myiasis which were caused accidentally by LATRINE (FANNIA) fly larvae during defecation or sleeping and ended spontaneously. The third male case was cutaneous myiasis pubis in which the causative

A 68 year old man presented with ulceration on his right ala nasi and upper lip. He had a fifth nerve ablation for trigeminal neuralgia four years previously. On examination he had a crescentic deep ulcer on the right ala nasi and nasolabial fold. There was also evidence of superficial ulceration on the right frontal scalp area. Neurological examination showed complete anaesthesia on the right side of the face. Numerous biopsies were taken to exclude vasculitis and neoplasia. Direct immunofluorescence studies were negative. Cultures were negative for mycobacteria, fungi and treponemes. Active herpetic infection was excluded by repeated Tzanck stains and viral cultures. On further questioning, the patient was reported by his family to pick constantly at the area. A diagnosis of trigeminal trophic syndrome was made. This is a rare sequela of damage to the sensory root of the fifth nerve.
