Bacteriological nasal flora in newborns indicating health and/or development of infection.

During delivery, a fetus otherwise sterile during the intrauterine life, comes in contact with bacterial flora of the mother's birth canal, and then also with the ward personnel's skin and respiratory system flora. Due to the absence of competitive bacteriological flora, the nasal cavity is gradually colonized by microorganisms, especially those with a capacity of adhesion to epithelial cells of respiratory nasal mucosa. Bacteriological flora of the newborn's nasal flora was observed on days 1 and 3 postpartum, in an attempt to determine whether a finding of pathogenic bacterial flora in newborn's nasal mucosa indicates a localized infection only or points to the possible development of generalized infection.

Clinical and cytomorphological alterations of nasal mucosa in laryngectomized patients.

A group of laryngectomized patients were rhinoscopically examined. The nasal mucosa was found to become thinner and change its colour over time. The nasal mucosa swabs from the same patients were cytologically examined at various time intervals following laryngectomy, revealing degenerative alterations of the multi-layered epithelium that occurred as a consequence of the nose exclusion from its function due to laryngectomy.

Interferon treatment of uterine cervical precancerosis.

Human leukocyte interferon (HLI) was used in a randomized study of patients with precancerous states on the uterine cervix. The daily dose of HLI was 10(6) units and its was applied by the contraceptive pessary technique. In patients how had had only viral alterations on the cervix the treatment lasted 14 days (Singer et al.
