[HIV infection. The risks for health providers and prevention and control measures].

The odontostomathologist and the dentist expose themselves to pathogenic agents present in the oral cavity. Taking in consideration at the present time the increasing number of seropositive patients, HIV infection and its pathogenic manifestations are of great interest. Considering that the main transmission of the virus is the ematic, the professional men who practise dentistry and the oral hygiene represent a particular risky class. For this reason they must adopt a series of preventive measures to protect themselves, their collaborators and the patient himself too.

[Neoplasms of the maxillary sinus. The clinico-radiological considerations of dental interest].

Early diagnosis of the maxillary antrum carcinoma is of considerable difficulty. There are, however, signs and a refined symptomatology that the stomatologist can recognize when the tumour is still in its intrinsic form. Although the maxillary antrum tumors are rare, they present an extremely difficult diagnosis. The patient comes to us when the tumor has already invaded all the contiguous structures pertaining to the oral cavity. For early diagnosis we can avail ourselves, besides a conventional radiographic test, also of more specific analysis, as the computed tomography and radio therapy. These last image methodologies are also employed to establish a radiation treatment plan. Actually the best therapeutic treatment seems to be the multidisciplinary one, combining therapy with surgery.

[Treatment of polymerized resins. A new method].

The resins used at present to prepare removable orthodontic equipment have surface characteristics which do not always correspond to the operator's requirements. The Authors are proposing a new methodology of treatment of the orthodontic products which will improve the outlook, the hygienic aspect and quite probably its byocompatibility.

Cardiac transplantation in Becker muscular dystrophy.

A 23-year-old man with X-linked Becker type muscular dystrophy underwent cardiac transplantation because of dilated cardiomyopathy which was complicated by terminal heart failure. Impairment of muscle function was mild and slowly progressive, whereas the cardiac disease was severe and rapidly progressive. All four chambers of the removed heart were grossly dilated; microscopically, the myocardial fibres were hypertrophic and pale; the nuclei exhibited pleomorphism with variability in nuclear size, shape, and depth of staining.

Dilated cardiomyopathy and successful cardiac transplantation in Becker's muscular distrophy. Follow-up after two years.

A 23 year-old man with x-linked Becker type muscular distrophy underwent cardiac transplantation because of dilated cardiomyopathy complicated by terminal heart failure. The muscular functional impairment was mild and slowly progressive, whereas the cardiac disease was severe and rapidly progressive. The ventricular cavities of the explanted heart were hugely dilated and the left ventricular wall thickness was moderately increased. Microscopically, a diffuse hypertrophy of the myocardial fibers and a widespread interstitial collagenous fibrosis were present. At a follow-up, two years after treatment, the patient is alive and fairly well; the degree of his muscular disability is substantially unchanged.

A hepatitis B vaccination programme in a group of dental practitioners.

A questionnaire concerning the acceptance of hepatitis B vaccination was mailed in April 1985 to 626 private dentists practicing in Milano and its county. Two hundred and twenty eight dentists (36.4%) filled out the questionnaire, 166 of them indicating their willingness to receive the vaccine. Between October 1985 and February 1986 we tested 241 practitioners for HBs antigen, anti-HBs and anti-HBc antibody, and SGPT (ALT) enzyme level. A 14.9% prevalence of HBV markers was found in the prevaccination testing. All persons with positivity for anti-HBs or HBsAg or with elevations of SGPT were excluded from the study (the latter temporarily). A few (42 or 20.9%) left spontaneously before the first dose of vaccine was administered. On the whole, 159 participants began the vaccination course. The proportion of vaccine recipients in dentists who indicated in the questionnaire their willingness to accept the vaccine and/or participated in a seroepidemiological survey performed in 1983 by some of us (85.1%) was significantly greater than that in the group of dentists who did neither (65.0%) (p less than 0.01). Educational effort appeared to be important to enroll and to counsel practitioners in implementing vaccination programme.

Hepatitis B virus infection in dentists and dental students.

To evaluate exposure to hepatitis B virus (HBV) in dental operators, we surveyed 297 students of the Dental School, University of Milano, and 526 dentists registered at the Italian Dental Association (A.M.D.I.) of Lombardia. Out of 297 students, 10.8% had one or more serologic markers of HBV infection; none was hepatitis B surface antigen (HBsAg) positive. No significant difference in seropositivity was detected among students in relation to sex, age, or possible risk factors investigated. Out of 526 practitioners, 2.3% were positive for HBsAg, and 37.3% were antibody positive. The seropositivity increased progressively with age and years of professional experience, reaching the highest proportion in dentists with 30 years or more of practice (79.3%). Of those who had suffered from clinical hepatitis during their curriculum, 81.1% were seropositive compared with 34.5% observed in dentists without a prior clinical history of viral hepatitis. The proportion of seropositive dentists did not vary significantly with a history of blood transfusion, size of their practice, presence or absence (or unawareness) of subjects at high risk for HBV infection among their patients. The seropositivity was significantly lower in dentists who routinely adopted mask and gloves (21.1%) compared with those who never and/or occasionally used such barriers (46.3%). The result of the study confirmed that hepatitis B does remain a significant hazard for dental professionals, hence immunization with hepatitis B vaccine should be delivered early in their employment.
