Plasma selenium levels of the general population of an area in northern Italy.

Plasma selenium (Se) levels of 293 subjects (160 males and 133 females) living in Desio (a small town near Milan) were determined. Analyses were performed by graphite-furnace atomic absorption spectrophotometry with Zeeman background correction. Plasma samples were not subjected to any treatment before analysis and serum samples containing a certified Se content were used as reference materials to control the quality of the analytical determinations. Plasma Se levels were found to be distributed normally with an average value of 118.8 micrograms/l and a S.D. of 27.2 (95% of the subjects lie between 64.4 and 173.2 micrograms/l). No statistically significant difference was found between males and females, and no correlation was found between plasma Se levels and age or smoking habits.

Diagnostic protocols for lymphoglandular toxoplasmosis.

The diagnostic protocol for lymph node toxoplasmosis presented in this study is based on the following sequence: 1. specific serologic tests (IHAT, IFAT, IgM-IFAT) on total serum and on purified IgM serum fraction, performed twice, within a time interval of 21-28 days; 2. Lymph node biopsy for histologic studies and for isolation of the parasite in mice (biologic test). A critical analysis is reported for 20 cases submitted to this protocol in the course of the year 1980.

[Biological basis of fluoride resistance].

The authors synthetically illustrate some fundamental concepts about the mechanisms through which the oral flora develops fluoride resistance and the main consequences of this phenomenon at a biochemical and microbiological level. They briefly discuss the most recent experimental contributes of the literature in this field.

[Relations between sodium fluoride sensitivity and cariogenic potential in Streptococcus mutans].

Supragingival plaque samples of a group of 59 schoolchildren were taken. The samples were cultivated on a selective medium for Streptococcus mutans and the isolated wild strains were tested for resistance to sodium fluoride (NaF). The results show the existence of a positive statistic correlation between the degree of resistance to NaF caries experience, obtained by DMFS of the experimental group.

[The hospitalized terminal cancer patient and privacy: patient needs and the perception on the part of the professional nurse].

The perception of privacy in a sample of 43 oncology patients admitted to cremona Hospital was evaluated with an ad hoc questionnaire administered by nursing students. The same questionnaire was completed by the nurse responsible for the patient and results were thereafter compared. The questionnaire, of 13 items, explored 4 domains of privacy: environment, physical care, communication with relatives, communication with care providers. Patients and nurses were asked to score each question from 0 (not important) to 3 (very important). Situations which involved modesty-physical care and communication-socialization were perceived as most important for privacy. Areas perceived very important for privacy by the patient received a very high score from the nurses as well.
