Dissertação Acesso aberto (Open Access) Descrição de outras doenças sexualmente transmissíveis em pessoas infectadas pelo vírus da imunodeficiência humana do tipo 1(Universidade Federal do Pará, 1998) MESQUITA, Francisco Carlos Lopes de; ISHAK, Ricardo; http://lattes.cnpq.br/5621101706909450Ninety patients seroreactive to HIV-1 were studied in order to describe the clinical manifestations of other sexually transmitted diseases as well as the demographic and behaviour factors associated to the HIV-1 infected and AIDS patients. The majority (83.3%) were males with a mean age of 31.4 years of age (range between 18 and 60 years) and a monthly family income for 79.5% of less than five mininum wages. At least one type of ilicit drug was used by 51.1% and 20.7% were intravenous drug users. Among them, 94.4% referred to a previous episode of a sexually transmitted disease. The subjects revealed that 41.6% were bisexuals, 38.2% heterosexuals and 20.2% were homosexuals. Approximately 51.1% of the bisexual subjects were intravenous drugs users and all referred to have had ano-rectal intercourse and were all positive for the presence of antibodies to Chlamydia. The mean age of the first sexual relation with penetration and the first episode of sexually transmitted disease were at 14.7% and 20.6% years of age, respectively. The vast majority (95.5%) of the subjects experienced multiple sexual partners before the knowledge of their HIV-l positive serology status. Among the 73.3% that referred a previous episode of sexually transmitted diseases, 82.2% also referred urethral discharge, syphilis and herpes simplex. At physical examination, 36.6% (33/90) presented urethral, anal and vaginal discharge and genital lesions such as discharges (51.1%), vesicles (18.1%), warts (18.1%), lymphadenopathy (18.1%), ulcers (12.1%) and papules (6%). Reaction to the VDRL and antibodies to Chlamydia were present in 13.7% and 96.4%, respectively. The vast majority referred ano-retal intercourse and previous episodes of sexually transmitted diseases.Dissertação Acesso aberto (Open Access) Perfil epidemiológico e prevalência de doenças sexualmente transmissíveis em escolares da área urbana no município de Porto Velho - Rondônia(Universidade Federal do Pará, 2003-12-16) FREITAS, Virgina Tereza Neta; ISHAK, Ricardo; http://lattes.cnpq.br/5621101706909450Sexually Transmitted Diseases (STD) are widespread public health concern, majority among adolescents, because they are most susceptible in respect of the sexuality. Early sexual initiation, multiple sex partners, and lack of condom use are considered risk factors and contribute to the increase in the number of STD cases. In order to better understand high-risk sexual behavior among students, a crosssectional study based on a self-answered anonymous questionnaire was conducted in Joaquim Vicente Rondon High School, a public school of Porto Velho city, Brazil. To verify STD's prevalence, samples of blood, urethral and vaginal discharge had been analyzed. A total of 122 students aged 11 to 19 years participated in the study. 84% known what is a STD, 82,8% informed always using condoms during sex, 11,5% didn't make use of condom, and 5,7% selected their sexual partner. To identify STD variety an enzyme-linked immunosorbent assay (ELISA test) and bacterioscopia by method of gram had been applied. 83 blood samples had been analyzed by ELISA test, and 41 smear tests had been stained by method of gramo The incidence to Chlamydia was observed in 65,3% of females, and 34,6% of young men. Gardnerella vaginalis, Candida albicans and Trichomonas vaginalis were more common pathogenic microorganisms found.Dissertação Acesso aberto (Open Access) Risco ocupacional da infecção pelo vírus da hepatite B em centro obstétrico de hospital público de Porto Velho, Rondônia(Universidade Federal do Pará, 2003-12-16) SANTANA, Elaine Maria de; ISHAK, Ricardo; http://lattes.cnpq.br/5621101706909450The prevalence of HBsAg and anti-HBc was described in 168 individuals, distributed in 3 groups: 88 in-patients of the obstetric service, 61 health professionals of the obstetric center (PA CO) and 19 administrative employees (control group), all working at the Hospital de Base Dr. Ary Pinheiro - in Porto Velho, capital o fthe state of Rondônia. In the period of November and December of 2000 and January of 2001 serum samples were collected, for HBV detection using an enzyme immunoenzymatic assay (ELISA). The prevalence of the HBsAg was 1,1% of the obstetric patients, 3,3% in PAS/CO and 52,6% in the control group. For anti-HBc the positive results were 5,3% in the control group, 27,3% in the patient's group and 42,6% in the PAS/CO group. The study by age groups related to the positive serology, demonstrated that from 15 to 25 years and 25 to 35 years the prevalence of HBV was larger, for the patients and control, and in the groups of PAS/CO the higher prevalence was from 45 to 55 years. The high prevalence of HBV in the patient's way lead to a high prevalence of vertical transmission. The positive numbers of 1he control group is in agreement with the endemic characteristic of the population of Porto Velho. Factors as the number of sexual partners, the use of preservatives and the level of education in the PAS/CO group were compared with serological results for HBV. The organic fluid and the most referred exposure via of contamination or PAS/CO were the blood and cutaneous, 43% and 22% respectively.
