ABSTRACT
We present a simple technique for keeping the form of artificially expanded endophalli in bees (Hymenoptera). Endophalli were inflated using the introduction of low melting-point agarose from a syringe inserted in the anterior opening of the metasoma. Under refrigeration, the endophalli kept their expanded shape for up to three days allowing the description of structure, morphometric analyses, and examination of the external sculpturing of the cuticle under scanning electron microscope. The technique provides new possibilities for the study of functional morphology, sexual selection, and reconstruction of bee phylogeny.

Myiasis is a parasitic infestation caused by larvae of several fly species. Diagnosis and treatment are simple. This infestation is, however, rarely seen in the vulvar area. We present a short review of the disease and the case of a 19-year-old pregnant girl with vulvar myiasis and concomitant syphilis, vaginal trichomoniasis and genital candidiasis. The patient was also positive for human immunodeficiency virus.

A miíase é uma infecção parasitária causada por larvas de diversos tipos de moscas. Embora o reconhecimento e tratamento sejam fáceis, constituem uma infecção pouco freqúente na região vulvar. Este estudo apresenta uma revisão a respeito da patologia por miíase e a descrição do caso de uma adolescente de 19 anos, gestante, portadora de miíase vulvar associada à tricomoníase, candidíase e sífilis, além se ser soropositiva para HIV.
