Compliance with infection control procedures among California orthodontists.

We conducted a survey of a random sample of California orthodontists and of general dentists to compare their infection control procedures. Questionnaires were returned by 124 orthodontists (56% response rate) and 126 general dentists (61% response rate). Eighteen questions were asked covering practice profile, perception of risk from hepatitis B virus (HBV) and human immunodeficiency virus (HIV), exposure to blood, barrier protection used, and sterilization and disinfection procedures. Gloves always were worn by 80% of the orthodontists sampled, 63% always wore glasses, and 59% changed gloves between patients. Orthodontists sterilized their instruments 66% of the time and pliers 49% of the time. Compared with general dentists, orthodontists' perception of risk, use of barrier protection, and sterilization and disinfection procedures were lower in all areas. Our data suggest that poorer performance may be because orthodontists: (1) perceive their younger population of patients at less risk for HBV and HIV; (2) treat 2.5 times as many patients, which increases the costs of infection control; (3) do not use invasive procedures; and (4) perceive that glove use decreases dexterity. Orthodontists should follow the American Dental Association/Council on Dental Therapeutics infection control guidelines for universal precautions. To meet these guidelines, orthodontists still need improvement in all aspects of their infection control procedures.

Sweet's panniculitis.

We report the development of acute, tender, erythematous plaques in a 65 year old female with Myelodysplastic Syndrome transforming to Acute Myeloid Leukaemia. The clinical presentation strongly suggested Sweet's syndrome. Histopathological examination of the plaques showed a normal epidermis, dermal and subcutaneous oedema, and large numbers of polymorphs in the panniculus. The eruption responded quickly to systemic steroids, with recrudescence when steroid dosage was reduced. She remained symptom free when prednisolone dosage was reduced more slowly.

Adenocarcinoma in a female urethral diverticulum.

Carcinoma occurring within a diverticulum of the female urethra is an exceedingly rare disease for which the treatment is ill-defined. We present here the first reported case of this condition from Australasia and review some of the recommendations for treatment.

Increasing incidence of tuberculosis in a prison inmate population. Association with HIV infection.

The incidence of tuberculosis (TB) among inmates of the New York State prison system increased from 15.4 per 100,000 in 1976 through 1978 to 105.5 per 100,000 in 1986. Matching of TB and acquired immunodeficiency syndrome registries indicated that the majority (56%) of inmates with TB reported in 1985 and 1986 had acquired immunodeficiency syndrome or human immunodeficiency virus infection; none were known to be human immunodeficiency virus seronegative. A case-control study examined 59 inmates with TB reported from 1984 through 1986 and 59 matched control inmates without TB. Inmates who reported street drug use were more likely to develop TB: odds ratio, 9.7; 95% confidence interval, 2.8 to 33.6 and odds ratio, 7.3; 95% confidence interval, 0.9 to 59.3 by unconditional and conditional logistic regression analyses, respectively. Although the majority of cases are thought to be due to reactivation of latent infection, phage typing of 16 Mycobacterium tuberculosis cultures suggested the possibility of inmate-to-inmate transmission in at least one cluster of three cases. It is of crucial importance that TB control measures be reinforced in the prison setting to counter the increased risk created by human immunodeficiency virus infection.

AIDS and dental practice.

Dental health care workers (DHCWs) can provide important diagnostic, treatment, and referral services for patients with AIDS and at risk for AIDS. They also have a responsibility to protect all patients in their practices, and themselves, from infectious disease transmission through the use of infection control. To determine the extent to which DHCWs are prepared to assume these responsibilities, a randomized survey of California DHCWs was conducted. Responses were obtained from 297 dentists, 128 hygienists, and 177 dental assistants. DHCWs who expressed a greater willingness to treat people with AIDS or HIV infection also practiced more thorough infection control. Respondents in all groups who perceived a greater percent of their patients to be at risk for AIDS were more likely to use infection control procedures (P less than .0001). They also were more willing to treat such patients (P less than .004) and were more likely to assess patients for AIDS by taking a thorough medical history (P less than .02) and sexual history (P less than .04). Since attitudes toward AIDS and perception of the percent of patients at risk in one's practice affect patient assessment and infection control procedures used by dental health care workers, educational programs designed to enhance DHCWs' response to the HIV epidemic should alert them to the extent of the problem and help them cope with their concerns.

Changing dentists' knowledge, attitudes, and behaviors relating to AIDS: a controlled educational intervention.

The efficacy of an educational intervention designed to improve dentists' knowledge, attitudes, and behaviors about acquired immune deficiency syndrome (AIDS) was tested. The intervention had three components: computerized feedback comparing participants' own knowledge, attitudes, and behaviors with those of fellow participants and with an ideal; periodic bulletins; and telephone conference calls with experts. The group receiving the educational package had better scores than a control group on outcomes of willingness to treat persons with AIDS; identification of human immunodeficiency virus lesions; knowledge of AIDS; and completeness of both intraoral and extraoral examinations. It was concluded that intervention is one approach to increasing dentists' positive response to the AIDS epidemic.

Recent graduates' evaluation of their dental school education.

To assess recent dental graduates' perceptions about the adequacy of their education, a random sample of individuals who graduated between 1980 and 1982 was surveyed. The 362 respondents (56 percent response rate) indicated their perceived level of preparedness and the importance to practice of 75 topics in the dental school curriculum. The means for level of preparedness and importance to practice were plotted for each of the 75 topics. Those topics that new dentists believed to be underemphasized or overemphasized in the curriculum were identified. These findings have implications for planning curricular changes for dental education.

Extent of urinary excretion of p-hydroxyphenytoin in healthy subjects given phenytoin.

Urinary excretion of p-hydroxyphenytoin and its glucuronide conjugate was measured in eight healthy young adults in a comparative bioavailability study of oral sodium phenytoin (approximately 5 mg/kg/dose). Among these subjects the percentage of the phenytoin dose converted to p-hydroxyphenytoin and appearing in urine was relatively similar (mean 79%, range 67-88%). The great majority of the p-hydroxyphenytoin appeared in urine as conjugates; only 1.4-3.4% of the excreted p-hydroxyphenytoin was in the form of unconjugated metabolite. The proportion of a single phenytoin dose excreted in urine as p-hydroxyphenytoin or its conjugate increased from the first dose (mean +/- SD) 74.9 +/- 4.6% to the second dose, given 2 weeks later 79.3 +/- 4.6% (p less than 0.05). This finding suggests that autoinduction of phenytoin metabolism may occur after relatively brief exposure to the drug.
