RESUMO
Congenital tuberculosis (TB) is uncommon, and diagnosis may be delayed. We report a case of congenital TB and the management of exposure in three different neonatal intensive care units. This case demonstrates the need for a high index of suspicion, active communication among maternal and neonatal medical providers, and timely provider reporting of maternal disease, and emphasizes the relatively greater risk of transmission to health care workers versus infants in this setting.

SETTING: In resource-poor countries, few tuberculosis (TB) program staff at the national, provincial, and even district levels have the basic analytical and epidemiological skills necessary for collecting and analyzing quality data pertaining to national TB control program (NTP) improvements. This includes setting program priorities, operations planning, and implementing and evaluating program activities. OBJECTIVES: To present a model course for building capacity in basic epidemiology and operations research (OR). DESIGN: A combination of didactic lectures and applied field exercises were used to achieve the main objectives of the 6-day OR course. These were to increase the understanding of quantitative and qualitative research concepts, study design, and analytic methods, and to increase awareness of how these methods apply to the epidemiology and control of TB; and to demonstrate the potential uses of OR in answering practical questions on NTP effectiveness. As a final outcome, course participants develop OR proposals that are funded and later implemented. RESULTS: Since 1997, this OR course has been conducted nine times in five countries; 149 key NTP and laboratory staff have been trained in OR methods, and 44 OR protocols have been completed or are underway. CONCLUSION: This low-cost model course can be adapted to a wide range of public health issues.

Strain W, a highly drug-resistant strain of Mycobacterium tuberculosis, was responsible for large nosocomial outbreaks in New York in the early 1990s. To describe the spread of strain W outside New York, we reviewed data from epidemiologic investigations, national tuberculosis surveillance, regional DNA fingerprint laboratories, and the Centers for Disease Control and Prevention Mycobacteriology Laboratory to identify potential cases of tuberculosis due to strain W. From January 1992 through February 1997, 23 cases were diagnosed in nine states and Puerto Rico; 8 were exposed to strain W in New York before their diagnosis; 4 of the 23 transmitted disease to 10 others. Eighty-six contacts of the 23 cases are presumed to be infected with strain W; 11 completed alternative preventive therapy. Strain W tuberculosis cases will occur throughout the United States as persons infected in New York move elsewhere. To help track and contain this strain, health departments should notify the Centers for Disease Control and Prevention of cases of tuberculosis resistant to isoniazid, rifampin, streptomycin, and kanamycin.

OBJECTIVES: To evaluate the impact of Occupational Safety and Health Administration (OSHA) regulations on the vaccination of healthcare workers (HCWs), to assess interpretation of these regulations, and to evaluate changes in hospital vaccination policies. DESIGN: Between June 1, 1992, and August 15, 1992, a telephone survey was conducted among 150 hospitals selected randomly from participants in the American Hospital Association 1991 annual survey. RESULTS: Of the 150 hospitals, 96 (64%) provided information on hepatitis B vaccination coverage of their employees. Of the 103,419 employees in these hospitals, 77,302 (75%) were eligible to receive the hepatitis B vaccine, and 38,850 (51%) of these were vaccinated completely (had received 3 doses of vaccine). Following issuance of the final regulations, 73% of hospitals reported greater employee acceptance of hepatitis B vaccine, and hospitals were more likely to offer hepatitis B vaccine to maintenance workers, security personnel, dietary staff, and clerical personnel. Seventy-five hospitals (50%) reported conducting postvaccination serologic testing on all hospital employees, 12 (8%) as a result of OSHA regulations. Twenty-three hospitals (16%) reported administering routine booster doses of hepatitis B vaccine at 3, 5, or 7 years. CONCLUSIONS: The new OSHA standard resulted in a greater awareness of risk for HBV infection among HCWs and an increase in the number of HCWs receiving hepatitis B vaccine; however, vaccination coverage remained suboptimal. Postvaccination serologic testing of employees with negligible risk and the routine administration of vaccine booster doses may be diverting resources and preventing comprehensive coverage of high-risk employees.
