RESUMO

We studied predictors of no prenatal care (PNC) and influence of no PNC on pregnancy outcome in a multisite study of 1071 women with syphilis in Russia. We assessed PNC utilization, HIV testing, syphilis treatment, and pregnancy outcome. We found that 37% of women with syphilis received no PNC, and 1% was HIV infected. Lacking official residency status was independently related to no PNC (adjusted odds ratio [AOR]: 8.1; 95% confidence intervals [CI]: 5.3-12.3). Among women with inadequately treated current syphilis, those without PNC were more likely to have a stillborn infant than those with PNC (25% vs. 3%, odds ratio [OR] 9.5, 95% CI 4.0-23.5). Women with adequately treated current syphilis and no PNC were more likely to deliver a low birth weight (OR 3.8; 95% CI 1.8-8.1) or preterm infant (OR 3.9; 95%CI 1.8-8.7). Women with previous or current syphilis and no PNC were significantly more likely to abandon their infants.

RESUMO

BACKGROUND: Three patients with identical strains of M tuberculosis (TB) underwent bronchoscopy on the same day at hospital A. METHODS: We reviewed each patient's clinical history, hospital A's infection control practices for bronchoscopies, and specimen and isolate handling at each of 3 laboratories involved. We searched for possible community links between patients. Restriction fragment length polymorphism was performed on TB isolates. RESULTS: The first patient who underwent bronchoscopy had biopsy-confirmed granulomatous pulmonary TB. A sputum sample collected from the third patient 6 weeks after the bronchoscopy produced an isolate with an identical restriction fragment length polymorphism pattern to isolates collected during the bronchoscopies. No evidence existed for community transmission or laboratory contamination; the only common link was the bronchoscopy. Different bronchoscopes were used for each patient. Hospital ventilation and wall-suctioning were functioning well. Respiratory technicians reported sometimes reusing the nozzles of atomizers on more than one patient. A possible mechanism for transmission was contamination from the first patient of the atomizer if it was used to apply lidocaine to the pharynx and nasal passages of other patients. CONCLUSIONS: A contaminated atomizer may have caused TB transmission during bronchoscopy. Hospital A changed to single-use atomizers after this investigation.

RESUMO

OBJECTIVES: The present study was carried out in seven maternity hospitals to determine the prevalence of maternal syphilis at the time of delivery and the associated risk factors, to conduct a pilot project of rapid syphilis testing in hospital laboratories, to assure the quality of syphilis testing, and to determine the rate of congenital syphilis in infants born to women with syphilis at the time of delivery--all of which would provide baseline data for a national prevention programme in Bolivia. METHODS: All women delivering either live-born or stillborn infants in the seven participating hospitals in and around La Paz, El Alto, and Cochabamba between June and November 1996 were eligible for enrolment in the study. FINDINGS: A total of 61 out of 1428 mothers (4.3%) of live-born infants and 11 out of 43 mothers (26%) of stillborn infants were found to have syphilis at delivery. Multivariate analysis showed that women with live-born infants who had less than secondary-level education, who did not watch television during the week before delivery (this was used as an indicator of socioeconomic status), who had a previous history of syphilis, or who had more than one partner during the pregnancy were at increased risk of syphilis. While 76% of the study population had received prenatal care, only 17% had syphilis testing carried out during the pregnancy; 91% of serum samples that were reactive to rapid plasma reagin (RPR) tests were also reactive to fluorescent treponemal antibody-absorption (FTA-ABS) testing. There was 96% agreement between the results from local hospital laboratories and national reference laboratories in their testing of RPR reactivity of serum samples. Congenital syphilis infection was confirmed by laboratory tests in 15% of 66 infants born to women with positive RPR and FTA-ABS testing. CONCLUSION: These results indicate that a congenital syphilis prevention programme in Bolivia could substantially reduce adverse infant outcomes due to this disease.

RESUMO

BACKGROUND: During a college football game in Florida, diarrhea and vomiting developed in many of the members of a North Carolina team. The next day, similar symptoms developed in some of the players on the opposing team. METHODS: We interviewed those who ate the five meals served to the North Carolina team before the game and some of the players on the opposing team who became ill. Patients with primary cases were members or staff of the team who had vomiting or diarrhea at least 10 hours after but no more than 50 hours after eating a box lunch served the day before the game. Patients with secondary cases had a later onset of symptoms or had symptoms without having eaten the box lunch. Stool samples were examined by electron microscopy and by a reverse-transcription-polymerase-chain-reaction (RT-PCR) assay. RESULTS: The two football teams shared no food or beverages and had no contact off the playing field. Of five meals served to the North Carolina team before the game, only the box lunch was associated with a significant risk of illness (relative risk of illness, 4.1; 95 percent confidence interval, 1.6 to 10.0). The rate of attack among those who ate the box lunch was 62 percent. There were 11 secondary cases among the members and staff of the North Carolina team and 11 such cases among the Florida players. All four stool samples obtained from North Carolina patients were positive for Norwalk-like virus on electron microscopy. All four samples as well as one of two stool samples from players on the Florida team were positive for a Norwalk-like virus of genogroup I on RT-PCR assay; the RT-PCR products had identical sequences. CONCLUSIONS: This investigation documents person-to-person transmission of Norwalk virus among players during a football game. Persons with acute gastroenteritis should be excluded from playing contact sports.

RESUMO

Both dogs and humans can be coinfected with various Ehrlichia, Bartonella, Rickettsia, and Babesia species. We investigated a kennel of sick Walker Hounds and their owners in southeastern North Carolina for evidence of tick-borne infections and associated risk factors. A high degree of coinfection was documented in the dog population. Of the 27 dogs, 26 were seroreactive to an Ehrlichia sp., 16 to Babesia canis, and 25 to Bartonella vinsonii, and 22 seroconverted to Rickettsia rickettsii antigens. According to PCR results, 15 dogs were infected with Ehrlichia canis, 9 with Ehrlichia chaffeensis, 8 with Ehrlichia ewingii, 3 with Ehrlichia equi, 9 with Ehrlichia platys, 20 with a Rickettsia species, 16 with a Bartonella species, and 7 with B. canis. The detection of DNA from any Ehrlichia species was associated with clinical illness and with concurrent B. canis infection (by PCR). Both E. canis and an uncharacterized Rickettsia species appeared to result in chronic or recurrent infection. Death in the dog population was associated with living in a dirt lot rather than the concrete kennel. Of 23 people on whom serologic testing was conducted, eight were seroreactive to Bartonella henselae, one to E. chaffeensis, and one to R. rickettsii antigen; however, none had clinical or hematologic abnormalities consistent with illness caused by these organisms. We conclude that kennel dogs with heavy tick exposure can be infected at a high rate with multiple, potentially zoonotic, tick-borne pathogens. In addition, our findings further illustrate the utility of PCR for documenting coinfection with tick-transmitted pathogens.

RESUMO

OBJECTIVES: After a syphilis epidemic in Jefferson County, Texas, in 1993 and 1994, congenital syphilis prevalence and risk factors were determined and local prenatal syphilis screening practices were assessed. METHODS: Medical records were reviewed, pregnant women with syphilis were interviewed, and prenatal care providers were surveyed. RESULTS: Of 91 women, 59 (65%) had infants with congenital syphilis. Among African Americans, the prevalence per 1000 live births was 24.1 in 1994 and 17.9 in 1995. Of the 50 women with at least 2 prenatal care visits who had infants with congenital syphilis, 15 (30%) had received inadequate testing. Only 16% of 31 providers obtained an early third-trimester syphilis test on all patients. CONCLUSIONS: Inadequate prenatal testing contributed to this outbreak of congenital syphilis.
