In Brazil, an increasing proportion of new HIV infections and AIDS cases involve women of reproductive age. To describe the reproductive desire of women with HIV/AIDS and to identify factors associated with the desire for motherhood, a cross-sectional study was carried out in the referral hospital for infectious diseases in Ceará State, northeast Brazil. In total, 229 women were included in data analysis. Median age was 32 years (interquartile range, 26-37), and 63% had a monthly family income of less than 210 USD. Forty-nine percent were using a contraceptive method, and 37% wished to undergo tubal ligation. Sixty-four percent of the latter women were motivated by the fear of having an HIV-positive child. Forty percent of the participants wanted to have a child. In the multivariate regression analysis, variables independently associated with women's desire to have a child were: younger age (in years, odds ration [OR] = 0.94; 95% confidence interval [CI]: 0.90-0.98), number of children (OR = 0.73; 95% CI: 0.57-0.96), and partner's desire for a child (OR = 3.35; 95%CI: 1.75-6.39). Having a partner who did not know about the woman's positive serostatus was negatively associated with the woman's desire for a child (OR = 0.17; 95% CI: 0.04-0.69). No variable related to clinical status was significantly associated with the outcome variable. Our data showed that many unsterilized HIV-positive women in northeast Brazil, at whatever stage of illness, have a desire for children. We recommend that nondirective counseling, consisting of helping women evaluate their own feelings, goals and needs with respect to reproductive options be provided.

Background: Infestation with the human head louse (Pediculus humanus capitis) occurs worldwide. Existing treatment options are limited, and reports of resistance to commonly used pediculicides have been increasing. In this trial we assessed the efficacy of a product containing a high (92%) concentration of the silicone oil dimeticone (identical in composition to NYDA ® ), as compared to a 1% permethrin lotion.

Population-based data on sexually transmitted infections (STI), bacterial vaginosis (BV), Laboratory testing included polymerase chain reaction (PCR) for human papillomavirus (HPV), ligase chain reaction (LCR) for Chlamydia trachomatis and Neisseria gonorrhoeae, ELISA for human immunodeficiency virus (HIV), venereal disease research laboratory (VDRL) and fluorescent treponema antibody absorption test (FTA-ABS) for syphilis, and analysis of wet mounts, gram stains and Pap smears for trichomoniasis, candidiasis, and BV. Only women who had initiated sexual life were included in the analysis (n = 592). The prevalences of STI were , chlamydia 4. 5% (3.0-6.6), trichomoniasis 4.1% (2.7-6.1), gonorrhoea 1. 2% (0.5-2.6), syphilis 0. 2% (0.0-1.1), and HIV 0%. The prevalence of ) and 12. 5% (10.0-15.5 ), respectively. The most common gynaecological complaint was lower abdominal pain. STI are common in women in rural Brazil and represent an important health threat in view of the HIV pandemic.Key words: sexually transmitted infections -reproductive tract infections -prevalence -epidemiology -Brazil Sexually transmitted infections (STI) are a major cause of morbidity throughout the world, particularly in developing countries (Gerbase et al. 1998). In women, STI are often chronic and present with little or no symptoms, but eventually may lead to severe sequels, such as chronic pelvic inflammatory disease, ectopic pregnancy, and infertility (WHO 2000). The impact of STI on the health of women tends to be more severe in resourcepoor settings where diagnostic and treatment facilities are inappropriate. Here, women often are not aware of STI as health problems, and health care seeking behaviour is poor (Giffin & Lowndes 1999). Relatively high prevalences of STI have been documented in such settings e.g. from Brazil, Papua New Guinea, and The Gambia (Walraven et al. 2001, Mgone et al. 2002, Soares et al. 2003. STI, as well as bacterial vaginosis (BV), are considered to increase the risk of acquiring human immunodefiency virus (HIV) (Sewankambo et al. 1997, Rottingen et al. 2001.In Brazil, the HIV epidemic is characterized by changing dynamics, currently reaching new population groups, namely women, underprivileged individuals, and communities outside the great urban centres (Fonseca et al. 2000, Brazilian Ministry of Health 2006. Reliable epidemiological data from Brazilian women on STI and other reproductive tract infections (RTI), such as BV and candidiasis, are scanty. Syphilis and HIV in pregnant women, AIDS, and congenital syphilis are notifiable infections, but the epidemiologic situation of other RTI is rather enigmatic. Studies have addressed the issue of STI in certain specific groups, such as patients attending STI clinics, gynaecology and obstetric outpatient departments, female prisoners or commercial sex workers (Miranda et al. 2000, Benzaken et al. 2002, Codes et al. 2002, Cook et al. 2004. However, these studies do not allow to conclude on the burden of disease on the community level.To increase further the knowledge...

Abstract. We determined the seroprevalence of Toxoplasma gondii and associated risk factors among 963 pregnant women attending an obstetric hospital in Fortaleza, Brazil. Seroprevalences of IgG and IgM against T. gondii were 68.6% (95% confidence interval [CI] = 65.6-71.6%) and 0.5% (95% CI = 0.06-1.0%), respectively. Seroprevalence of IgG was high in women less than 25 years of age (91.7%) and in low-income women (odds Ratio [OR] = 1.40, 95% CI = 1.02-1.90). Multivariate regression analysis showed that consumption of homemade water ice (adjusted OR = 1.49, 95% CI = 1.09-2.04), vegetables washed with untreated water (adjusted OR = 1.43, 95% CI = 1.05-1.94), consumption of chicken (adjusted OR = 1.49, 95% CI = 1.12-2.0), and dog ownership (adjusted OR= 1.46, 95% CI = 1.07-1.98) were factors associated with IgG seropositivity. Young women in northeastern Brazil living under poor socioeconomic conditions are at highest risk for acquiring infection with T. gondii . Oocyst contamination of water and soil must be addressed in future prevention strategies.

SM was found at a high frequency in oral and vascular samples, even in edentulous patients, and its presence in atherosclerotic plaques suggests the possible involvement of this bacterium in the disease progression.

Infestation of the head louse Pediculus humanus var capitis DeGeer (Phthiraptera: Pediculidae) is an important public health problem in Australia, with up to a third of children infested in some primary schools. Insecticide resistance and inadequate attention to the application instructions of topical pediculicides are common reasons for treatment failure. This study evaluated six popular Australian over-the-counter products against head lice, primarily comprised of different botanical extracts, and compared them with permethrin 1% (Quellada) and a non-treatment control in order to assess their in vitro efficacy. We also assessed commonly used criteria for evaluating pediculicide efficacy in vitro. All tested products failed to demonstrate high levels of efficacy with the exception of Tea Tree Gel((R)), which outperformed 1% permethrin. Permethrin had a high level of efficacy, but using stringent criteria 18% of lice were not dead at 3 h, indicating some resistance to Quellada. Commonly used less stringent criteria were shown to overestimate mortality of head lice as a result of the protective phenomenon of stasis or sham death observed in exposed lice that may recover after some time. Using two different levels of stringency resulted in different rankings of efficacy for most products, with the exception of the first ranked product, Tea Tree Gel. Rankings of efficacy also varied over time, even within the different assessment criteria. Government regulatory agencies should require standard in vitro tests using stringent mortality criteria, with an observation period of >or= 6 h, to determine the efficacy of new pediculicides, and only products that cause a minimum mortality rate (e.g. 80%) in head lice collected from the target population should be licensed for sale.

Structural deficiencies and functional abnormalities of heart valves represent an important cause of cardiovascular morbidity and mortality, and a number of diseases, such as aortic stenosis, have been recently associated with infectious agents. This study aimed to analyze oral bacteria in dental plaque, saliva, and cardiac valves of patients with cardiovascular disease. Samples of supragingival plaque, subgingival plaque, saliva, and cardiac valve tissue were collected from 42 patients with heart valve disease. Molecular analysis of Streptococcus mutans, Prevotella intermedia, Porphyromonas gingivalis, and Treponema denticola was performed through real-time PCR. The micro-organism most frequently detected in heart valve samples was the S. mutans (89.3%), followed by P. intermedia (19.1%), P. gingivalis (4.2%), and T. denticola (2.1%). The mean decayed, missing, filled teeth (DMFT) was 26.4 ± 6.9 (mean ± SD), and according to the highest score of periodontal disease observed for each patient, periodontal pockets > 4 mm and dental calculus were detected in 43.4% and 34.7% of patients, respectively. In conclusion, oral bacteria, especially S. mutans, were found in the cardiac valve samples of patients with a high rate of caries and gingivitis/periodontitis.
