The rising prevalence of HIV among pregnant women in rural India is of great concern. Prenatal voluntary counseling and HIV testing (VCT) is critical to prevent mother-to-child transmission of HIV (PMTCT). We surveyed 202 pregnant women attending a rural antenatal clinic in Southern India to investigate HIV-related knowledge, attitudes toward infant feeding practices, and perceived benefits and risks of HIV testing. Of the total of 202 women surveyed, 189 women (94%) had heard of HIV/AIDS and 60% of them had relatively good knowledge regarding risk factors for HIV transmission. However, 48% did not know that there are "means to prevent mother-to-child HIV transmission." If women were not to breastfeed her baby, negative attitudes expected from the partner would include 84% thinking that that the mother is harming the baby, 78% thinking she is not a good mother, 74% thinking she has HIV, and 66% thinking she has been unfaithful. Ninety-seven percent of women did not perceive themselves at risk for HIV and only 57% had been tested for HIV. Although, 85% of women expressed their willingness to be tested, most were concerned about confidentiality and disclosing HIV serostatus because of fear of negative reactions from their husbands, parents, and community. Many social and cultural barriers confront pregnant women when they decide to opt for HIV testing. If VCT and PMTCT interventions are to be successful, urgent attention must be focused on education, development of innovative culturally appropriate interventions that empower women to make decisions about HIV testing, involvement of men, and addressing stigma and discriminatory attitudes toward people living with HIV/AIDS.
Introduction:Lipid oxidation gives rise to number of secondary by-products. Malondialdehyde (MDA) is the principal and most widely studied product of polyunsaturated fatty acid peroxidation. This aldehyde is a highly toxic molecule and should be considered as more than just a marker of lipid peroxidation in oral carcinogenesis.Materials and Methods:Salivary malondiadldehyde was evaluated in 65 healthy controls (HC), 115 subjects with oral, potentially malignant disorders (PMD) and 50 subjects with oral squamous cell carcinoma (OSCC) using the Thiobarbituric-Trichloroacetitic acid (TBA-TCA) method.Results:A consistent elevation in the levels of salivary MDA was observed in HC with tobacco related habits, subjects with PMD and subjects with OSCC. The elevation in the salivary MDA was significant (P = 0.001) in the groups PMD and OSCC and group OSCC when compared to HC.Conclusion:The significant and encouraging findings of this study thus validate and reinforce that salivary malodialdehyde analysis can be used as an efficient, noninvasive tool for the early diagnosis of PMD and OSCC for planning comprehensive treatment protocol.
Oral cancer accounts for the majority of the cancer in South East Asian region and especially in the Indian subcontinent. If diagnosed at an early stage the disease is reported to have a better prognosis. Recently studies have been conducted to determine the levels of serum antioxidants for risk assessment of oral cancer. The aim of this study was to estimate the levels of glutathione in serum of patients with oral cancer, oral leukoplakia and healthy controls. Three study groups comprising of, 25 oral cancer patients, 25 oral leukoplakia patients and 25 healthy controls were involved in the study. Serum sample collected from the patients by venipuncture were evaluated by Beutler's method. The data obtained were analyzed using the one way ANOVA test. There was a significant difference between the levels of serum glutathione in between oral cancer, oral leukoplakia groups when compared to healthy controls. The levels of serum glutathione were lower in oral cancer when compared to oral leukoplakia but the difference was not statistically significant. The results suggest that serum glutathione level estimation could be used to determine the risk of oral cancer.
Background:Oral submucous fibrosis (OSMF) is one of the most commonly occurring potentially malignant disorders in India and south East Asian countries where betel chewing is common practice. Iron and ascorbic acid are important agents for collagen synthesis.Aims:The aims of this study were to estimate the levels of iron and ascorbic acid in serum and saliva in patients with OSMF and to correlate change in levels of iron and ascorbic acid with the histopathological grading of OSMF.Materials and Methods:The study group comprised of 65 clinically diagnosed and histopathologically confirmed cases of OSMF; 21 age- and sex-matched controls were also enrolled in the study. Serum and salivary ascorbic acid were analyzed by the dintrophenyl hydrazine method whereas serum and salivary iron were analyzed by the dipyridyl method.Results:The serum and salivary ascorbic acid levels consistently decreased with the progression of histopathologiocal grading of OSMF. Serum and salivary iron levels were also decreased in OSMF patients, but this was not significant.Conclusion:Ascorbic acid and iron may have been used for the excessive collagen synthesis occurring during progression of OSMF. Hence, serum and salivary monitoring may play a crucial role in the early diagnosis and prognosis of OSMF.
In the SouthEast Asian countries oral cancer is one among the commonly occurring malignancies due to tobacco use and quid chewing habits. Early stage diagnosis of the disease is reported to have a better prognosis. Sialochemistry studies involving antioxidants have recently gained importance as biomarkers for oral cancer risk assessment. The aim of this study was to estimate the levels of superoxide dismutase in saliva of patients with oral cancer, oral leukoplakia and healthy controls. Three study groups comprising of 25 oral cancer patients, 25 oral leukoplakia patients and 25 healthy controls were involved in the study. Saliva sample collected from the patients were evaluated superoxide dismutase by nitroblue tetrazolium (NBT) chloride method. The data obtained were analyzed using the one way ANOVA test. There was a significant difference between the levels of salivary superoxide dismutase in between oral cancer, oral leukoplakia groups when compared to healthy controls. The levels of salivary superoxide dismutase were significantly lower in oral cancer when compared to oral leukoplakia. These results suggest that salivary superoxide dismutase level estimation could be used to determine the risk of oral cancer as a non-invasive modality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
