Prophylaxis for occupational exposure to HIV

Article Abstract:

Doctors currently recommend a four-week preventive treatment with zidovudine and lamivudine for health professionals accidentally exposed to HIV-infected blood. Preliminary research has shown that the average risk for infection (0.3%) after an injury involving HIV-infected blood can be reduced by nearly 80% with preventive treatment. The risk may be higher for those repeatedly exposed to infected blood and if the virus level in the exposed blood is high. Treatment with indinavir may be advisable if the exposure is extensive or if the infected patient carries a virus resistant to treatment.

Accidental exposures to blood and body fluids among health care workers in dental teaching clinics: a prospective study

Article Abstract:

Clinical dental teaching situations appear to be a source of substantial risk for exposure to infections carried by blood or body fluids. Questionnaires were completed by 428 dental or allied dental students or professionals exposed to body fluid or blood at one of four dental teaching clinics. Sixty percent of the exposures involved wounds inflicted by dental instruments while 36% involved needle sticks. Dental assistants and dental students reported the highest numbers of exposures. Respondents indicated that concentration, stress, and time were factors in their injuries.

Occupational Exposures to Body Fluids among Medical Students: A Seven-Year Longitudinal Study

Article Abstract:

Medical students are at risk of needlestick injuries, which could expose them to bloodborne diseases. In a study of all third- and fourth-year medical students at one medical school over a 7-year period, 119 students were exposed to a patient's blood from a needlestick injury. Despite training in infection control procedures, injuries continued to be reported to a needlestick injury hotline over the 7-year period. Eighty-two percent of the injuries occurred during obstetrics-gynecology, surgery, medicine, and emergency medicine clerkships.
