Bedbugs (Cimicidae infestation): the worldwide renaissance of an old partner of human kind

Bedbugs have been known as a human parasite for thousands of years, but scientific studies about this insect are recent and limited. Cimex lectularius, the common bedbug, was a well-known parasite in human dwellings until the end of the Second World War. Nowadays, bedbugs are considered uncommon in the industrialized world. Anecdotal reports suggest that bedbugs are getting more common in the United States, Canada, and United Kingdom. In Brazil, there are few reports about bedbug infestations in the literature. The aim of this article was to alert physicians, especially in Brazil, about this ectoparasitosis, including aspects of the bedbug biology, their parasitism in human host, treatment and prophylaxis.748

Reação a drogas com eosinofilia e sintomas sistêmicos (DRESS) / Síndrome da hipersensibilidade induzida por droga (DIHS): revisão dos conceitos atuais

The Drug Reaction with Eosinophilia and Systemic Symptoms syndrome, also known as Drug Induced Hypersensitivity Syndrome presents clinically as an extensive mucocutaneous rash, accompanied by fever, lymphadenopathy, hepatitis, hematologic abnormalities with eosinophilia and atypical lymphocytes, and may involve other organs with eosinophilic infiltration, causing damage to several systems, especially to the kidneys, heart, lungs, and pancreas. Recognition of this syndrome is of paramount importance, since the mortality rate is about 10% to 20%, and a specific therapy may be necessary. The pathogenesis is related to specific drugs, especially the aromatic anticonvulsants, altered immune response, sequential reactivation of herpes virus and association with HLA alleles. Early recognition of the syndrome and withdrawal of the offending drug are the most important and essential steps in the treatment of affected patients. Corticosteroids are the basis of the treatment of the syndrome, which may be associated with intravenous immunoglobulin and, in selected cases, Ganciclovir. The article reviews the current concepts involving this important manifestation of adverse drug reaction

Cimidíase (dermatose por percevejo): uma causa de prurigo a ser lembrada Bedbugs (Heteroptera, Cimicidae): an etiology of pruritus to be remembered

Descrevemos uma doente de 19 anos que nos procurou com quadro de intenso prurido há 2 semanas e demonstrando lesões eritêmato-pápulo-urticadas mais intensamente distribuídas nos membros superiores e inferiores. A anamnese detalhada excluiu causas internas e medicamentos como uma possível causa do prurigo. Após orientações quanto a dedetização do domicílio a doente retornou no consultório após 3 semanas sem lesões cutâneas e trazendo em um pote de vidro vários percevejos coletados após a dedetização.<br>This report describes a 19-year old female patient, who sought medical attention for severe itching of two weeks' duration. Erythematous papules and wheals were found, principally on her upper and lower limbs. Careful anamnesis excluded other etiologies of the pruritus, including those related to internal diseases and medication. Following counseling regarding the need to contract a domestic pest control company, the patient returned to the clinic three weeks later with no skin lesions and bearing a glass jar containing several bedbugs collected following pest control treatment
