Evaluation of Milan University Dental Students' knowledge of health and hygiene risks related to clinical work.

AIM: Several different subjects in the Degree Course in Dentistry and Prosthodontics, including Hygiene, are of fundamental importance to understand and prevent hygiene/ health risks in the dental field. The aim of this investigation is to evaluate the knowledge acquired by students during the Degree Course in Dentistry. METHODS: A questionnaire was distributed to 121 students of the Degree Course in Dentistry and Prosthodontics at Milan University; the questionnaire, drawn up by the Working Group SItI ''Hygiene in Dentistry'' was structured in 3 parts: personal data; transmission of infectious diseases in dentistry; measures to control and prevent cross-infection. RESULTS: The students were all aware of the health/hygiene risks in dentistry; they knew the principal transmissible infectious diseases (while confusing actual risk of transmission with disease's fears) and the procedures at highest risk of cross-infection for patients and dental professionals; they correctly determined the highest-risk categories of patients and the individual protection devices to be used in dental practice. However, they knew little about their own vaccination status; a low percentage of students answered correctly on which environmental matrices can be contaminated or the more technical questions on disinfection and sterilisation procedures for the instruments employed. CONCLUSIONS: The students' replies show they possess a fair theoretical knowledge of transmission risks; however, some gaps exist above all in the practical application of this knowledge, and it appears clear that these should be addressed in detail, possibly with the help of a specific tutor providing support during normal clinical work in the last year of the course.

[Dental offices and environment quality].

AIM: The aim of this study was to survey, from a microbiological point of view, dental unit water, air and surface quality in public dental offices and in control environments in Milan. METHODS: We studied tap and dental unit water (from fountain, air-water syringe, turbine), at the beginning and at the end of monday and thursday morning activity; air quality with surface air system (SAS) in dental and control offices; handpieces holder, fountain block, arm of the light, dental trolley, inner and outer walls surfaces quality. RESULTS: Water from the dental unit waterline shows average exceeding the law limits 2-3 fold for total bacteriological counts at 37 degrees and 22 degrees, in all examined points, at the beginning of the working day. There is an improvement in the water contamination at the end of the activity. Pseudomonas aeruginosa is frequently found, total and fecal coliforms are absent, while Legionella pneumophila was found only in one control. Air and surfaces quality is quite good, especially in places with ventilation systems in function. CONCLUSION: Dental unit water is the most critical point among those monitored. Water quality has to be improved with specific projects.

[Hygiene-sanitary risks associated with dentistry in the city of Milan. Questionnaire-based survey].

BACKGROUND: Aim of this investigation is to identify possible sanitary risks connected with the practice of dentistry and to draw up guidelines which may help all those who work in this field. METHODS: Between April and July 1998, we distributed 231 questionnaires to public and private dental offices in Milan, to evaluate dentists' knowledge of sanitary risks in their practices. One hundred and sixteen of the 231 distributed questionnaires were returned. All the dentists contacted, used protective measures such as gloves, masks, glasses, and high-speed aspirators. RESULTS: Survey responses indicated that the most readily transmittable infectious diseases in dentist's practices are, in order of importance, hepatitis, AIDS, airborne diseases, and herpes. Surgery, endodontics, and the use of sharp instruments most likely lead to transmission of pathogens in both patients and dentists. Dentist's knowledge of out-patient treatment is good whereas their knowledge of the use of disinfectants for dental equipment is poor. CONCLUSIONS: The latter suggests the utility of continuing education in this critical aspect of the practice of dentistry.

[Anti-hepatitis B vaccination in health personnel at the Ospedale Maggiore of Milan].

The paper deals with the screening of the staff at the Ospedale Magiore of Milan within the Region-wide program of recommended B Hepatitis vaccination. The HBsAg positive subjects are 3.1% and antiHBs are 32.7%; the susceptibility of the infection decreases with age and working seniority; infection markers are found most frequently in subjects working in the Dialysis Ward. The health staff informed about the professional risk of infection is still reluctant for this immunization; in fact only 62.5% of susceptible accepted the vaccine. Seroconversion was observed in 89.8%; collateral reactions to vaccine were of minor importance and short duration.

[Antipneumococcal vaccination: comparison between vaccines].

Fourteen antigen and 17 antigen polyvalent vaccines against Str. pneumoniae have been tested on 137 healthy volunteers. They have been shown to cause side-effects infrequently. A two-fold or higher increase of antibody concentration (detected by RIA) has been demonstrated in 80% of the vaccinees against all antigens of the 17 valent vaccine; while such increase has been demonstrated only for 12 out of 14 antigens in the other vaccine (for the other two antigens the percentages have been 66.7% (antigen 1) and 73.7% (antigen 12F). It is stressed that the use of these vaccines is particularly recommended for the prevention of pneumococcal diseases in higher risk subjects.

Interference of the phosphodiesterase inhibitor aminophylline with the plant cell cycle.

Aminophylline (an inhibitor of animal phosphodiesterases) interferes with a pleiotypic program in embryos and seedlings of Haplopappus gracilis, inducing a specific and reversible block of the cell cycle in G1 and G2, partial depression of RNA and protein synthesis and inhibition of the uptake of nucleosides and leucine. The analogy between these effects and those evoked in animal cells by various treatments leading to a rise in cAMP level is discussed.

[Prevalence of tetanus immunity in metal mechanical workers].

The results of a seroepidemiological prevalence survey on the immune status against tetanus of steelmill workers (who, limited to the new work call ups, had to be vaccinated since 1968) are reported. We did not observe remarkable differences in protection against tetanus among those who had begun work before 1968 (46.4% protected) and after 1968 (53.5% protected). In both cases, the protective values were the result of immunization procedures that were performed exclusively in consequence of the military service and/or on the occasion of industrial accident and/or road accident or of accidents of other kinds. It appears, moreover, that the protection of workers against this disease is, nowadays, too often relying on serum prophylaxis, which was the only preventive measure adopted for over half of the workers. In the light of the reported data we need to enforce the existing legislative measures.
