Pharyngeal pseudodiverticulum in an adult.

Posterior perforation of the cervical portion of the esophagus may present deceptive clinical and roentgenographic pictures. In the neonate, the clinical picture resembles that of esophageal atresia; in the adult, the roentgenographic appearance may resemble Zenker diverticulum. In either instance, treatment should be no different from that employed for more commonplace esophageal perforations, namely, prompt, aggressive surgical intervention.

[Vaginal secretion hyaluronidase activity levels in normal and in some pathological conditions. Physiological pictures in a clinical series].

A viscometric method was used to determine vagina hyaluronidase activity in 82 healthy subjects. Enzyme values (in micrograms) were referred both to a volume unit and to a standard protein unit. Each subject was also examined colposcopically, cytologically, bacteriologically and cytohormonally.
