ABSTRACT

A miíase de localização vulvar é doença rara. O objetivo do presente relato é descrever um caso de miíase vulvar por larvas de Cochliomyia hominivorax em mulher de 77 anos, com precários hábitos higiênicos, apresentando dor, prurido e secreção de odor fétido na região genital há 10 dias. O exame ginecológico demonstrou lesão ulcerada no grande lábio vulvar, com seis centímetros, que se estendia ao monte do pube, preenchida por larvas. A doente evoluiu favoravelmente após remoção das larvas, desbridamento cirúrgico e curativos diários, sendo realizada, quatorze dias após o desbridamento, rotação de retalho cutâneo. Apresentou evolução satisfatória, estando assintomática dois meses após a intervenção. A miíase vulvar deve ser considerada no diagnóstico diferencial das doenças infecciosas vulvares de doentes com hábitos de higiene precários.

    • "It is one of the most important of the nearly thousand of species of Calliphoridae, as larvae of C. hominivorax are obligate parasites of domestic and wild mammals, including humans (Guimarães & Papavero 1999). Zoonotic infestations by larvae of C. hominivorax are of great public-health importance, and people inadequate hygienic habits are the most likely to have cutaneous lesions and/or systemic diseases, and are, consequently, highly susceptible to the infestation by this type of parasite (Martinez et al 2003).

    ABSTRACT: Myiases are infestations with dipteran larvae in both necrosed and living tissues, the food source of these insects. These illnesses occur in warm humid climates, and are most frequent in developing countries. We assessed the epidemiological aspects and the influence of climate on the occurrence of myiases and the bioagents in patients admitted to the federal Hospital do Andaraí in Rio de Janeiro from February 2007 to 2008. The influence of abiotic factors (temperature, humidity, and rainfall) on the incidence of myiases was investigated by using the Pearson's correlation test. Of the 40 patients studied, the prevalence of myiases was higher in adults, particularly in the 40 to 65 year-old (37.5%) African descent males (57.5%). Most of the injuries were caused by trauma (62.5%). Some patients made use of licit (50%) and illicit drugs (17.2%). The occurrence of myiases was not affected by the abiotic factors investigated. The cases reported here were treated in only one hospital, indicating that the disease is relatively common. The most frequent bioagent was Cochliomyia hominivorax (Coquerel), but Cochliomyia macellaria (Fabricius), Chrysomya albiceps (Wiedemann) and Dermatobia hominis (Wiedemann) (Diptera: Calliphoridae) were also detected causing myiases. Chrysomya albiceps is an exotic etiologic agent of myiases.

    ABSTRACT: Tungiasis and myiasis are common ectoparasitic infestations that occur in developing countries in the tropics, particularly where poverty and poor standards of basic hygiene exist. The growth in international travel to and from these regions has led to an increase in the presentation of these conditions in nonendemic countries. Despite recent progress in the treatment and prevention of tungiasis and myiasis, diagnosis can present a challenge to those unfamiliar with these conditions, especially when they present in nonendemic countries. Tungiasis is caused by the penetration of the female sand flea, Tunga penetrans, into the epidermis of the host. Myiasis is a parasitic infection of the skin and mucous membranes in which the larvae of Diptera insects penetrate healthy or altered skin depending on the species. Infestations are usually self-limited and present few complications. Social neglect and inadequate health behavior in economically depressed urban neighborhoods, however, may lead to secondary infections and complications.

    ABSTRACT: This was a descriptive epidemiological study with the aim of evaluating the occurrence of human myiasis in urban areas of four municipalities in the State of Rio de Janeiro. Seventy-one patients who spontaneously sought attendance at primary healthcare units between October 1999 and October 2003 were examined. The disease was more prevalent among adults, including in individuals more than 51 years old (42.3%), and among children less than 10 years old (33.8%). From all the cases studied, 62% were of low socioeconomic level; 60.6% were male; and 33.8% of the infested individuals were unemployed. In the cases analyzed, the bioagent species were Cochliomyia hominivorax (Coquerel, 1858), Dermatobia hominis (Linnaeus Jr, 1781) and Cochliomyia macellaria (Fabricius, 1775). The results point towards an association between the disease and the patients living and hygiene conditions. This indicates the need for more specific healthcare among more vulnerable groups.
