Prevalence of HPV and associated factors in a population of women living in southern Brazil.

Objective: To determine the prevalence of HPV and investigate factors associated with the infection in women in the city of Francisco Beltrão, southwest Paraná, attending the public health system.

Methods: This cross-sectional study included 324 women, aged between 18 and 65 years, who were attending public health services for routine gynecological consultation. Interviews were conducted to obtain information about socioeconomic, sexual, gynecological, and life habits.

University Students' Knowledge about the Relation between Human Papillomavirus (HPV) and Head and Neck and Oral Cancers.

Introduction: Human papillomavirus (HPV) causes the most common sexually transmitted infection (STI) in the world. It affects people regardless of gender and age, causing genital warts and cancer.

Objective: To evaluate university students' knowledge of HPV and its relationship with head and neck and oral cancers.

GSTT1 and GSTM1 polymorphisms with human papillomavirus infection in women from southern Brazil: a case-control study.

Background: Important risk factors for the most common sexually transmitted infection (STI) in the world, human papillomavirus (HPV), include early sexual activity, use of contraceptives, tobacco smoking, and immunological and genetic factors. This study aimed to investigate the relationship between GSTM1 and GSTT1 polymorphisms and HPV infection and associated risk factors in a group of women assisted in the public health system of southwestern Paraná, Brazil.

Methods And Results: A case-control study was designed with 21 women with HPV matched by age in the case group and 84 women without the virus in the control group.

Evidence on Human Exposure to Pesticides and the Occurrence of Health Hazards in the Brazilian Population: A Systematic Review.

Brazil is among the biggest pesticide consumers in the world, with its population severely exposed to tons of such substances, both because of environmental contamination and occupational use. The health consequences of pesticide exposure are well-documented, but still sparse regarding Brazilian population. This study systematically reviewed the Brazilian studies published that address the relationship between exposure to pesticides and health problems in the Brazilian population.

Prevalence and factors associated to cervical changes in units from the Single Health System.

Objective: To estimate the prevalence and risk factors associated with cytopathological changes in the uterine cervix of women treated by the Unified Health System.

Method: This is a cross-sectional study carried out with 350 women, between 14 and 79 years old who underwent pap smear tests in heath units in Francisco Beltrão, Paraná. Cervical cytopathological analyses and a questionnaire were applied to obtain socioeconomic information, as well as data on sexual behavior, gynecological aspects, and life habits.

Relationship between GSTM1 and GSTT1 polymorphisms and HPV infection: a systematic review.

Human Papillomavirus (HPV) is the most important risk factor for cervical cancer, although not the only one. The allelic polymorphism of enzymes acting on carcinogen metabolism has shown to influence the risk of both intraepithelial lesions and cervical carcinogenesis. Several studies found an association between GSTM1/GSTT1 null genotypes and risk of cancer.
