r n i v e r s i t y TWO PLATES (EIQHT FIQURES)The hedonic glands, located on the sides of the head of the male Triturus, seem to play an important role in the mating behavior of the newts; their secretion serves to attract the female during courtship. The development and anatomy of these glands have been described by Hilton ( '02), who found that they were rudimentary in the female, but in the male attained a certain level of development at the time of sexual maturity, and became greatly hypertrophied each year a t the approach of the mating season.Noble ('29) has described glands of similar function in the male plethodontid salamanders in which, however, the glands are not restricted to one location but are widely scattered over the dorsal surface, being abundant on the eyelids, temporal region, and especially the base of the tail. The relation of these hedonic glands to the sex hormones was investigated by Noble ('31), who removed the ovaries from adult Desmognathus fuscus females and implanted testes. Hedonic glands appeared in the skin of the base of the tail 62 to 220 days after implantation. They resembled young granular glands of the integument, but apparently arose independently of both these and the mucous glands.Many recent papers indicate that the hypophysis-gonadreproductive tract interrelationship, so strikingly demonstrated for mammals, prevails also in amphibians.

Mujer de 83 años de edad que ingresa por cuadro de astenia, anorexia, dolor abdominal y vómitos. Paciente con antecedentes de colitis ulcerosa en tratamiento con salazopirina. Durante el ingreso presenta fiebre y persiste el dolor abdominal. En TAC abdómino-pélvico (Fig. 1) se evidencia colección hidroaérea pélvica, parasigmoidea sospechosa de poder corresponder a un área volvulada de sigma o un absceso de origen diverticulítico. En colonoscopia, diverticulosis de sigma con zona rígida entre divertículos que ofrece resistencia a la progresión del endoscopio. Debido a los hallazgos se instaura tratamiento antibiótico y TAC de control (Fig. 2) con punción si es oportuno. Al realizar este, se observa que dicha colección hidroaérea presenta en la actualidad un contenido exclusivamente aéreo.
