article 34 Citação(ões) na Scopus Bedbugs (Cimicidae infestation): the worldwide renaissance of an old partner of human kind(2011) CRIADO, Paulo Ricardo; BELDA JUNIOR, Walter; CRIADO, Roberta Fachini Jardim; SILVA, Roberta Vasconcelos e; VASCONCELLOS, CidiaBedbugs 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.- Extensive long-standing chromomycosis due to Fonsecaea pedrosoi: Three cases with relevant improvement under voriconazole therapy(2011) CRIADO, Paulo Ricardo; CARETA, Mariana Figueiroa; VALENTE, Neusa Y. S.; MARTINS, Jose Eduardo Costa; RIVITTI, Evandro A.; SPINA, Ricardo; BELDA JR., WalterObjective: To evaluate voriconazole in the treatment of extensive cases of chromomycosis. Chromomycosis is a chronic infection, which is extremely difficult to eradicate, and is caused by dematiaceous (dark-colored) fungi which affect the skin and subcutaneous tissues, with Fonsecaea pedrosoi being the major etiologic agent. Drugs such as itraconazole, terbinafine, posaconazole and amphotericin B have been employed with variable results. Methods: We treated three Caucasian male patients (ages 44, 57 and 77 years), two were farmers and one a trash collector, with long-standing (20, 10 and 21 years of disease, respectively) and extensive chromomycosis (one lower limb affected, at least) due to Fonsecaea pedrosoi. All patients had received previous therapy with the formerly indicated drugs itraconazole and terbinafine for several months either without or with incomplete response. After that, we started treatment with voriconazole per os 200 mg twice a day. Results: The patients were treated with voriconazole for 12 months until there was clinical and mycological improvement. Clinical response was evident after 30-50 days. One patient developed visual abnormalities and tremors, and the voriconazole was reduced to 200 mg/day without impairment of the clinical and mycological response. The same patient presented photosensitive dermatitis after 12 months of therapy and the voriconazole was stopped. All patients showed elevations of serum gamma-glutamyl transpeptidase (GGT) during the treatment without clinical relevance. Moreover, our three patients obtained partial response with this therapy. Conclusions: This is the first report with a case series of chromomycosis treated with voriconazole. Despite its high cost, voriconazole is a safe and possibly promising drug for use on extensive chromomycosis refractory to conventional treatment.

article Zoon's plasma cell balanitis: a report of two cases treated with pimecrolimus(2011) DELGADO, Livia; BRANDT, Hebert Roberto Clivati; ORTOLAN, Damaris G.; PATRIOTA, Regia Celli Ribeiro; CRIADO, Paulo Ricardo; BELDA JUNIOR, WalterInitially called (in French) ""Balanoposthite chronique circonscrite benigne a plasmocytes"", Zoon's plasma cell balanitis is a chronic inflammatory dermatosis affecting the glans and foreskin of uncircumcised men. The different treatment options for this condition often present partial results. Reports have shown therapeutic success using topical tacrolimus. We report the use of pimecrolimus, a homologue of tacrolimus, with good response. Two male patients diagnosed with Zoon's plasma cell balanitis, confirmed by biopsy, were subjected to daily treatment with topical pimecrolimus1%. Significant improvement was noted in patient 1 after 6 weeks and after 8 weeks in patient 2. Conclusion: Pimecrolimus cream may be an option for the treatment of this disease.
