Perception of HIV among pregnant women in the public health system in two municipalities of the state of São Paulo

Aim: To verify the knowledge of pregnant women on mother-to-child transmission (MTCT) of HIV, the availability of HIV tests in the public health system and counseling on the disease in two cities, Birigui and Piacatu, São Paulo State, Brazil. Methods: This is a descriptive and exploratory research using as samples, the files of 141 pregnant women attending the Basic Health Unit. Data were collected by survey, followed by a semi-structured questionnaire with open and closedend questions. Data were analyzed on Epi Info™ 7.1.4, by the Chi-square and Exact Fisher tests. Results: From all the 141 pregnant women, 119 were interviewed and 92.4% reported to have been informed about the need of taking the HIV test during prenatal exams. However, only 5.9% were counseled and 20.2% reported to be aware of how to prevent MTCT of HIV, usually mentioning lactation suppression and prescribed medication. The association between the knowledge about how to prevent MTCT of HIV and some social, demographic and economic variables like ethnics, educational level, home location, occupation, age and parenting was not verified. Conclusions: It is necessary to advise pregnant women on the importance of taking the HIV test regardless of the examination outcome, which was not observed in the cities where the research was conducted.

Efficacy of entecavir and tenofovir in chronic hepatitis B under treatment in the public health system in southern Brazil

There are about 350 million hepatitis B virus (HBV) carriers worldwide and chronic HBV is considered a major public health problem. The objective of the present study was to assess the effectiveness of the nucleos(t)ide analogues tenofovir (TDF) and entecavir (ETV) in the treatment of chronic HBV. A cross-sectional study was carried out from March-December 2013, including all patients with chronic HBV, over 18 years of age, undergoing therapy through the public health system in southern Brazil. Only the data relating to the first treatments performed with TDF or ETV were considered. Retreatment, co-infection, transplanted or immunosuppressed patients were excluded. Six hundred and forty patients were evaluated, of which 336 (52.5%) received TDF and 165 (25.8%) ETV. The other 139 (21.7%) used various combinations of nucleos(t)ide analogues and were excluded. The negativation of viral load was observed in 87.3% and 78.8% and the negativation of hepatitis B e antigen was achieved in 79% and 72% of those treated with ETV or TDF, respectively. Negativation of hepatitis B surface antigen was not observed. There was no occurrence of adverse effects. This is a real-life study demonstrating that long-term treatment with ETV and TDF is both safe and effective.

Dentists’ actions about oral health of individuals with Down Syndrome

Aim: To investigate the knowledge and actions of dentists for treatment of individuals with Down syndrome. Methods: A questionnaire was applied to all the dentists (n=90) working at the FHS (Family Health Strategy) modules in the urban limits of Parnaíba, PI, Brazil. Four of the questions in the questionnaire were written according to the Theory of Planned Behavior Table and Likert scale (questions 6,7,9 and 15), in order to analyze the professionals’ intentions. Sixteen objective questions were elaborated with the purpose of collecting information about the degree of the dentists’ knowledge as regards the intention of attending courses in the patients with special needs area including DS, and interaction with other professionals and families. The option was to use a questionnaire applied to the dentists of the region, from August to November 2014. Results: It was found that most professionals were women and they considered themselves able to identify these patients. Among the professionals, 70% showed they had no difficulty in identifying the patient with DS, and 5.2% had no opinion about the subject. Only 6.6% of the professionals showed to be certain about their aptitude to attend to these patients; 70% were partially apt, that is, they were not absolutely sure about their aptness. There was a statistical relationship between the variables understanding and difficulty in the treatment. There was no statistical relationship between the variable capacity to identify, understanding of the needs and fitness variable in attendance. Conclusions: Patients with Down syndrome need more attention and care of dentists, they must also be involved in a multidisciplinary approach. Most of the professionals do not follow the procedures laid down by the Ministry of Health, but showed interest in attending a course in this area and there is a low number of SD patients being cared in Parnaíba, PI.

Oral health quality of the workers of a telemarketing company and their satisfaction with the treatments provided by the corporative dental insurance plan

Aim: To evaluate the oral health quality of the workers of a telemarketing company and their satisfaction with the dental treatments provided by the corporative dental insurance plan. Methods: Data collection was by an online intranet questionnaire on dental service providers from Uberlândia/MG and Campinas/SP. It was addressed to 6000 associates, with objective and subjective questions, comprising the level of the telemarketing operators’ oral health, dental needs, satisfaction with dental care providers and the importance of having the laboral dental services provided by the company. Results: After analysis of the results, we observed that: 57.52% of the workers required improvement in their oral health and 56.03% mentioned prevention as the largest need, 66.70% use the dental providers’ services, but only 31.34% were satisfied with them. Conclusions: The results underscore that the workers have an intermediate level of dental needs, with prevention as top importance. Additionally, establishment of a basic attention program inside the company would increase the satisfaction and adhesion indexes of providers and the workers’ oral health.

Impact of dental caries on quality of life of adolescents according to access to oral health services: a cross sectional study

Aim: This study presents the prevalence of dental caries and its relation to the quality of life of adolescents according to the access to dental health services. Methods: Two hundred and fifty-six adolescents between 15 and 19 years of age participated in the study; they were all enrolled in public schools in a countryside municipality of the São Paulo State. Data related to dental caries were evaluated by the DMFT Index, and OHIP-14 was used for evaluating the quality of life. Mann Whitney and Spearmann correlation tests were also used (p<0.05). Results: A DMFT of 3.09 (±3.30) was found with a higher prevalence among the adolescents who used public dental services (3.43±3.34) compared with those who used private services (2.94±3.28). A statistically significant relationship between the decay component of DMFT with physical pain (0.020), physical disability (0.002) and quality of life (0.017) was verified. Conclusions: A low prevalence of dental caries was observed, and it was higher in adolescents who used public oral health services rather than private ones, evidencing the low influence of oral health on the quality of life of the participants.

Non-use of Formal Health Services in Malawi: Perceptions from Non-users

Background The study upon which this paper is based was undertaken to understand users’ and non-users’ perceptions concerning facilitators and barriers to equitable and universal access to health care in resource-poor countries such as Malawi. In this study, non-users of health services were defined as people who were not in need of health services or those who had stopped using them due to significant barriers. Methods A total of 80 interviews with non-users of health services were conducted in Rumphi, Ntchisi, Phalombe and Blantyre Districts of Malawi. Interviews focused on why informants were not using formal health services at the time of data collection. In order to identify non-users, snowballing was used health surveillance assistants, village headmen and community members also helped. One focus group discussion was also conducted with non-users of health services who were members of the Zion Church. Results Informants described themselves as non-users of health services due to several reasons: cost of health services; long distances to health facilities; poor attitude of health workers; belief in the effectiveness of traditional medicines; old age and their failure to walk. Others were non-users due to their disability; hence they could not walk over long distances or could not communicate effectively with health providers. Some of these non-users were complete non-users, namely members of the Zion Church and those who believed in traditional medicine, and they stated that nothing could be done to transform them into users of health services. Other non-users stated that they could become users if their challenges were addressed e.g. for those who were non-users of health services due to poor attitudes of health workers, they stated that if these health workers were transferred they would be able to access health services. Conclusions Public health education targeting both health workers and non-users, ensuring a functional outreach program and addressing other health system challenges such as shortage of drugs and human resources would assist in transforming non-users into users of health services.

Influence of factors in the oral mucosa maturation pattern: a cross-sectional study applying multivariate analyses

Aim: To evaluate the association between oral health status, socio-demographic and behavioral factors with the pattern of maturity of normal epithelial oral mucosa. Methods: Exfoliative cytology specimens were collected from 117 men from the border of the tongue and floor of the mouth on opposite sides. Cells were stained with the Papanicolaou method and classified into: anucleated, superficial cells with nuclei, intermediate and parabasal cells. Quantification was made by selecting the first 100 cells in each glass slide. Sociodemographic and behavioral variables were collected from a structured questionnaire. Oral health was analyzed by clinical examination, recording decayed, missing and filled teeth index (DMFT) and use of prostheses. Multivariable linear regression models were applied. Results: No significant differences for all studied variables influenced the pattern of maturation of the oral mucosa except for alcohol consumption. There was an increase of cell surface layers of the epithelium with the chronic use of alcohol. Conclusions: It is appropriate to use Papanicolaou cytopathological technique to analyze the maturation pattern of exposed subjects, with a strong recommendation for those who use alcohol - a risk factor for oral cancer, in which a change in the proportion of cell types is easily detected.
