INTRODUCTION: The Amblyomma genus is widely distribution in Brazil and is important regarding the public health risk represented by the transmission of pathogens. METHODS: This paper reports a case of parasitism in humans by Amblyomma sp that occurred in the City of Recife, State of Pernambuco.

Cercarial dermatitis in the UK.

'Swimmer's itch' or cercarial dermatitis (CD) results from an immunological reaction to free-swimming non-human schistosome parasites released from aquatic snails. Affected bathers develop a self-limiting, pruritic, macular or papular eruption shortly after leaving the water. The condition is well-recognized in continental Europe, Asia and America, but has not to date been recorded in the UK.

Leishmaniasis cutánea en la provincia de Toledo. Estudio de 43 pacientes / Cutaneous leishmaniasis in the Toledo province. A study of 43 patients

Se estudiaron 43 pacientes diagnosticados de leishmaniasis cutánea (botón de Oriente) que acudieron a la consulta de dermatología del Hospital Virgen de la Salud entre enero de 1990 y diciembre de 1997. Recogimos los siguientes datos clínicos: sexo, edad, número de lesiones, tiempo de evolución, forma clínica, tamaño y localización. El diagnóstico fue por biopsia cutánea o hallazgo del microorganismo en frotis de la lesión. Encontramos una alta proporción de mujeres (70 %) con dos picos de frecuencia en la edad de los pacientes, uno en menores de 14 años (30 %) y el otro entre 61 y 75 años (30 %).La lesión era única en casi todos los pacientes (91 %). El tiempo de evolución de las lesiones presentaba dos picos de máxima frecuencia (6 y 12 meses). La localización era fundamentalmente en áreas fotoexpuestas: 75 % en cara y 19 % en extremidades. La forma clínica era polimorfa. La forma papulonodular eritematosa con costra en superficie fue la más observada, con un tamaño entre 0,3 y 5 cm. La infiltración intralesional de antimoniales pentavalentes fue el tratamiento más empleado, con resultado satisfactorio. Discutimos los resultados de este trabajo y los comparamos con otras revisiones publicadas (AU)

[Onchodermatitis (sowda) in patients in Yémen. Clinical and histologic course after treatment with ivermectin]. / Onchodermatite (Sowda) chez des patients du Yémen. Evolution clinique et histologique après traitement par ivermectine.

Sowda skin lesions are of medical and social importance in Yemen. Ivermectin (Mectizan) chose as a control strategy plan in onchocerciasis is active during 3 months for the less on clinical and histological data. After a short increase of itching and oedematous skin aspects clinical signs decrease. Some patients notice an itching rebound after 90 days. Histologically, localized ingratiates, presence of mononuclear cells and melenin loaded histiocytes and eosinophils decreased. The rythm cure has to be studied on a longer period but 3 to 6 months repetition between oral treatment with 200 micrograms/kg dose during two years could be effective.

Furuncular myiasis from Dermatobia hominis infestation. Diagnosis by light microscopy.

Myiasis, the infestation of humans or other vertebrates with fly larvae, may appear as furuncular nodules. Furuncular myiasis occurring in the Western hemisphere, especially in Central and South America, is usually caused by Dermatobia hominis infestation. Travel history, gross examination, and histologic evaluation of the submitted fly larvae will allow the clinician and dermatopathologist to identify the causative organism. We report two cases of furuncular myiasis due to Dermatobia hominis and review the clinical and histopathologic findings pertinent to its diagnosis. In addition, we attempted to identify some of the cardinal internal structures of this organism by extrapolating known information about insect internal anatomy and physiology to the structures visualized during serial transverse sectioning of the larvae.

[Cercaria dermatitis (swimmer's itch). Case report of cercaria dermatitis caused by Trichobilharzia (Digena, Schistosomatidae)]. / Zerkariendermatitis (swimmer's itch). Fallbericht einer Zerkariendermatitis durch Trichobilharzia (Digena, Schistosomatidae).

A 63-year-old woman developed a pruritic exanthema on the extremities after one hour of work in her garden pond in Planegg, Southern Bavaria. As the appropriate vectors (ducks and snails) were present, we made the tentative diagnosis of cercarial dermatitis (swimmer's itch). By different serological methods (cercarial fluorescent antibody test, cercarial Hüllen reaction, circumoval precipitin test) antibodies against cercariae could be demonstrated in the serum of the patient 14 days later. Cercarial dermatitis appears worldwide, but in Central Europe the disease is often not recognized.

[Lucilia sericata infestation of the skin openings for the bone traction device in lengthening of the tibia: apropos of a case]. / Infestación por Lucilia sericata de los orificios cutáneos de osteotaxo en alargamiento de tibias: a propósito de un caso.

Fly larvae are responsible for animal disease well known by veterinarians. However, their finding in humans in nontropical countries is a rarity. Recently, we have found several larvae of Lucilia sericata in an achondroplastic child during the phase of lengthening of both tibiae with osteotax. We think that the myasis diagnosed in our patient is the first such case reported in the literature. For the time being, it should be considered a fortuitous finding and not as a complication of surgery.

Oral albendazole for the treatment of cutaneous larva migrans.

Cutaneous larva migrans is becoming more common in the U.K. with the popularity of tropical countries as holiday destinations. We describe the increasing use of a new benzimidazole derivative, albendazole, which is very effective in the treatment of cutaneous larva migrans. In contrast to thiabendazole, it is virtually free from side-effects and should, we feel, become the treatment of choice for this condition.
