[Person-oriented approaches to the psychologic assistance to pilots' teaching and training].

The author dwells upon the concept and practice of psychologic assistance to pilots' training and drilling, associated contradictions and issues that can be resolved by dint of ingenious training methods. One of these approaches is a person-oriented process of teaching, training and character building. The method was tested with a group of pilot students and some test results are described in the paper.

Radiation-induced increased platelet-activating factor activity in mixed saliva.

Background: Platelet-activating factor (PAF), a family of structurally-related phospholipid mediators of inflammation, is present in normal human mixed saliva; however, its role in oral biology and the homeostasis of oral host defense mechanisms remains to be established.

Experimental Design: The current study was designed to evaluate the salivary levels of PAF in patients with oral mucositis that developed as a complication of head and neck irradiation for oral cancer. PAF activity was assessed in platelet bioassay and expressed relative to the activity of authentic PAF, 1-O-hexadecyl-2-acetyl-sn-glycero-3-phosphocholine (C16:0-AGEPC).

Oral manifestations of neurofibromatosis types I and II.

The disease known as neurofibromatosis is now recognized to consist of distinct variants that differ from each other genetically, microscopically, and clinically. Neurofibromatosis type I (NF-I) is often referred to as von Recklinghausen's disease of skin, and its features are well known. Neurofibromatosis type II (NF-II) is a much more uncommon manifestation that probably results from a structural defect in chromosome 22, as opposed to NF-I, which is related to chromosome 17.

Infection control procedures in intraoral radiology: a survey of Michigan dental offices.

A questionnaire was mailed to members of the Michigan Dental Association to determine the extent and adequacy of infection control procedures utilized during intraoral radiography. These measures were then compared with the infection control guidelines recommended by the American Dental Association for exposing and processing radiographs. During exposure procedures, it was found that an overwhelming majority of practitioners wore disposable gloves and placed saliva-contaminated film packets in a receptacle after removing them from the mouth.
