ABSTRACT
RESUMEN Los accidentes causados por las setas urticantes o venenosas de las orugas de lepidópteros, se conocen como erucismo. Estos accidentes se producen por el contacto accidental, especialmente por los niños, con las cerdas sobre el cuerpo del insecto, conectadas con glándulas venenosas. Los síntomas pueden ser locales o sistémicos, con presentaciones clínicas fatales. El accidente ocasionado por las orugas del género Lonomia spp. puede desencadenar síndromes hemorrágicos, constituyendo estos la forma más grave de erucismo. Se reporta el caso de una niña de 5 años, procedente del poblado de Villarondos, en la Amazonía del Perú, departamento de Huánuco, la cual incidentalmente se hinca con las cerdas de una oruga, cursando luego con anemia hemolítica, plaquetopenia y trastorno de la coagulación. El diagnóstico fue establecido por la anamnesis, cuadro clínico, exámenes de laboratorio y respuesta al suero antilonómico. Se discuten los aspectos clínicos, laboratoriales y terapéuticos de erucismo por Lonomia spp.
ABSTRACT Accidents caused by urticating or poisonous setae from lepidoptera caterpillars are known as erucism. These accidents are produced by accidental contact, especially in children, with bristles on the insect's body surface, connected to venom glands. Symptoms may be local or systemic, with deadly clinical presentations. The accident caused by Lonomia spp. caterpillars can trigger bleeding disorders, which is considered the most severe type of erucism. The case of a 5-year-old girl is reported. She was from the town of Villarondos, in the Peruvian Amazon, department of Huánuco, who accidentally knelt down on caterpillar bristles, and subsequently experienced hemolytic anemia, plateletopenia, and coagulation disorder. The diagnosis was made based on the medical history, clinical manifestation, laboratory examination results, and response to antilonomic serum. The clinical, laboratory, and therapeutic aspects of erucism due to Lonomia spp. are discussed.

O presente artigo objetivou mostrar a distribuição dos acidentes com a lagarta Lonomia obliqua, Walker, 1855 no período de 1989-2001 no Estado do Paraná. Os dados foram obtidos junto a Secretaria de Saúde Ambiental do Paraná. As informações coletadas foram mapeadas utilizando-se o programa Arcview, sendo gerados mapas de ocorrência sazonal de acidentes. Esta sazonalidade foi correlacionada com o ciclo de vida do inseto, que indicou o período de verão como o de maior incidência de acidentes, e ocorrendo as maiores concentrações nas regiões centro-sul, sudeste e sudoeste do Estado.
The present article aimed to show the distribution of accidents involving the caterpillar Lonomia obliqua, Walker, 1855, in the State of Paraná between 1989 and 2001. The data were obtained from the Environmental Health Department of Paraná. The information collected was mapped using the Arcview program, and maps of the seasonal occurrence of accidents were generated. This seasonality was correlated with the insects life cycle and summer was shown to be the period with greatest incidence of accidents. The greatest concentrations occurred in the central-southern, southeastern and southwestern regions of the State.

Relata-se o caso de um homem de 44 anos, natural do Rio de Janeiro, residente no município de Teresópolis (RJ), vítima de um provável acidente por lagarta do gênero Lonomia, que evoluiu com quadro caracterizado por anemia hemolítica, plaquetopenia e insuficiência renal aguda. O diagnóstico de erucismo por Lonomia foi estabelecido a partir da anamnese e das manifestações clínicas e laboratoriais. O esquema terapêutico, baseado em hemodiálise e hemotransfusão, resultou em excelente resposta clínica. São discutidos os aspectos clínicos e fisiopatológicos do erucismo por Lonomia.

The first case of centipede (Scolopendra gigantea Linneaus 1758) envenomation in a newborn is reported. When first examined, approximately 6 hours after the bite, the 28-day-old girl was irritable, with uncontrollable cry and intense local pain, oedema, local hyperthermia, and blood clots at punctures. Uncontrollable crying in neonates should rise the possibility of an insect or arachnid sting
