Oral Myiasis Caused by Cochliomyia hominivorax in a Disabled Person.

Myiasis is a parasitic disease caused by developing maggots of fly species, which can infect humans. Patients with special needs, especially those with severe neuropsychomotor limitations, may have oral manifestations of this disease. Here, we present a clinical case in which a disabled person was affected by oral myiasis caused by Cochliomyia hominivorax. Maggots were found in two ulcerated lesions, a 2 cm diameter lesion in the maxilla and a 6 cm diameter lesion in the mandible. Forty-five maggots were removed during inspection, whereas 75 maggots were surgically removed under general anesthesia with nasotracheal intubation. Dipyrone, ivermectin, and clindamycin were prescribed, and the patient remained hospitalized for 3 days. Seven days after surgical intervention, no maggots were observed. Our study emphasizes that dentists must recognize the symptoms and behaviors of parasitic diseases that affect the oral cavity.

Análise epidemiológica dos traumas bucomaxilofaciais de um serviço de emergência / Epidemiological analysis of maxillofacial trauma of an emergency service

Objetivo: Analisar a epidemiologia dos traumas bucomaxilofaciais de um serviço de emergência. Metodologia: Estudo retrospectivo de corte longitudinal histórico realizado por meio da análise de prontuários de pacientes atendidos no serviço de emergência da Santa Casa de Misericórdia de Barretos, São Paulo, Brasil, no período de março de 2004 a abril de 2009. Resultados: Foram analisados 250 prontuários, sendo a maioria do gênero masculino (85%; n=213). Quanto a faixa etária, (36%; n=90) dos traumatismos bucomaxilofaciais ocorreram entre 26 a 40 anos de idade. Trinta e cinco por cento (n=87) dos pacientes foram vítimas de acidentes de trânsito. As agressões físicas corresponderam a (24%; n=60) das emergências realizadas. Vinte e dois por cento (n=55) dos traumas se enquadraram em "outros", 15% (n=38) dos traumas foram provocados por acidentes domésticos e 3% (n=8) por acidentes laborais. Um por cento (n=2) foi relacionado a acidente por arma de fogo. Conclusão: Os traumas bucomaxilofaciais são frequentes nos serviços de emergência e os acidentes de trânsito e a violência urbana são os principais fatores etiológicos desta epidemia... (AU)
