[Evaluation of the in vitro susceptibility pattern of clinical isolates of Trichophyton mentagrophytes and Trichophyton rubrum in Santiago, Chile].

Background: Dermatophytes are a group of keratinophilic fungi able to produce dermatophytosis or tinea infections. In Chile, Trichophyton rubrum and Trichophyton mentagrophytes are the ones most commonly isolated in adults, while Microsporum canis is found among children. Treatment of these infections is usually with topical or oral antifungals, such as griseofulvin or azole derivatives (clotrimazole, itraconazole, fluconazole), allylamines (terbinafine) or new drugs that are available.

[Group B streptococcus cellulitis-adenitis syndrome in neonates. Is it a marker of bacteremia?].

We report the case of an infant in whom facial cellulitis was the only initial sign of a group B streptococcal bacteriemia. Adenitis-cellulitis syndrome is a rare clinical manifestation of group B streptococcal infection in infants. Local infection together with the onset of fever can be the only signs of bacteriemia in newborns and infants.

Mucopolysaccharides in hypothalamic neurons of the rat.

A study of the hypothalamic nuclei of the rat, using a variety of histochemical methods, has shown the distribution of mucopolysaccharides and neurosecretory material. In all the hypothalamic nuclei there are two types of neurons and in some a third type characterized by the presence of hyaluronidase-resistant acid mucopolysaccharides in the periphery of the perikaryon. These type III neurons also contain Gomori-positive material and neutral mucopolysaccharides.
