Playing With Fire: Decrease in Safe-Sex Attitudes Among Men Who Have Sex With Men in a Portuguese STI Clinic

Background: Sexually transmitted infections (STIs) present a major public health concern and a global cause of illness in both industrialized and developing countries. Portugal is no exception, with an increasing incidence of STIs, and one of the highest prevalences of HIV in Europe. Reduced risk perceptions among men who have sex with men (MSM) and a consequent high-risk sexual behaviour have been increasingly reported throughout the world. Objectives: To characterize the population of MSM attending a STI clinic in Lisbon, and to assess practice of condom use among these patients. Methods: Records of all MSM patients who attended the STI clinic from 2008 to 2011 were reviewed to study demographic characteristics, sexual behaviours, and leading diagnoses in this population. Results: Of a total of 389 patients, 108 MSM were identified (27.8%), mostly Portuguese men with high school or above education, aged 17 to 61 years (medium age of 32.4 years). More than half of the patients (52.8%) reported more than one sexual partner in the past 6 months (19.4% more than 5 partners), and only a third consistently used condom. A history of sex with sex workers was mentioned in 9.2%. The most prevalent diagnoses were syphilis (45.6%) and condylomata acuminata (38.9%). The prevalence of HIV infection in this subgroup of patients was significantly higher than in the rest of the population (47.2% vs. 14.9%). Inconsistent condom use increased over the years (36.4% in 2008, 66.7% in 2011), and these patients revealed a greater number of sexual partners than condom users (60.4% vs. 50%). However, 38.9% of condom users presented with early syphilis, suggesting inadequate use of this barrier method. Among HIV patients, almost half of them (49%) had sex with more than one partner in the previous six months, and 47.1% did not use the condom during all sexual practices. Of these, 45.8% were not on antiretroviral therapy. Conclusions: High-risk sexual behaviours (inconsistent use of condom and multiple partners) are increasingly prevalent in this MSM subpopulation, despite previous educational programmes. The high incidence of risk behaviours among HIV infected patients is particularly worrisome, and must be addressed with innovative interventions and population-based prevention strategies.

Função Sexual após Braquiterapia Prostática de Baixa Taxa de Dose

A braquiterapia prostática de baixa taxa de dose é considerada uma opção terapêutica adequada para o carcinoma da próstata. É habitualmente, apresentada como a melhor forma de preservar a função eréctil de entre os diversos tratamentos de carcinoma da próstata. Contudo, estudos recentes demonstram que, também a braquiterapia prostática pode, no longo prazo, provocar algum grau de disfunção eréctil (DE). As taxas de DE nas diversas séries publicadas, são muito variáveis. Os resultados da influência da dose de radiação, isoladamente (D90) ou quando incidindo sobre o feixe neurovascular ou o bulbo são contraditórios. O tipo de isótopo utilizado não tem qualquer influência sobre a DE. No entanto factores como a idade, a função eréctil pré-tratamento, a diabetes, a utilização de radioterapia externa adjuvante e/ou hormonoterapia neoadjuvante podem condicionar os resultados obtidos. Otratamento da disfunção eréctil deve ser efectuado com inibidores da fosfodiesterase, obtendo-se boas taxas de resposta. Podem surgir outras alterações da função sexual, nomeadamente, hematospermia, dor durante o orgasmo e alteração da intensidade do orgasmo.

Saúde Sexual e Reprodutiva das Adolescentes - a Nossa Realidade

Overview and Aims: Several behavioral and biological factors can make adolescents particularly vulnerable to unwanted pregnancies and sexually transmitted diseases. The aim of this study was to evaluate sexual behavior and contraceptive use patterns of a population of adolescents. Study Design: Retrospective study. Population: 163 female adolescents attending an Adolescence Unit for the first time, during 2010. Methods: Analysis of clinical charts and assessment of demographic data, smoking and drinking habits, drug use, gynecologic and obstetric history, sexual behavior and contraceptive use. Results: The mean age was 16.04 years (±1.32). 71.7% were students (of these, 70% had failed one or more years and were behind in their studies), 2.5% were working and 23.9% were neither studying or working. 95.1% had already had sexual intercourse and the mean age of first coitus was 14.53 years (±1.24). There was a history of at least one previous pregnancy in 77.3% of the cases. Before the first appointment at the AU, the contraceptive methods used were: the pill (33.2%, but 41.3% of these reported inconsistent use), and the condom (23.9%, with inconsistent use in 28.3% of these cases). 19.6% did not use any contraceptive method.. After counseling at the AU, 54% of the teenagers chose the contraceptive implant and 35% preferred the pill. Adolescents who had already been pregnant preferred a long acting method (namely, the contraceptive implant)in 61.9% of cases; those who had never been pregnant decided to use an oral contraceptive in 67.6% of cases (p<0.001). Conclusions: After counseling the number of teenagers using contraception increased. In this population there were a high number of adolescents with a previous pregnancy. This factor seems to have influenced the choice of the contraceptive method, with most of these adolescents choosing a long-acting method.

Gravidez, Parto e Disfunção Sexual

Assunto apoiado ao longo dos séculos e culturas em preconceitos morais, religiosos e médicos, a sexualidade durante a gravidez e puerpério constitui ainda hoje motivo de grande ansiedade, condicionante da sexualidade do casal. Aproveitados pelas diferentes religiões, culturas e políticas, alguns conceitos mantiveram-se inalterados até ao século passado, altura em que uma maior abertura para as questões sexuais na sociedade em geral, despertou na comunidade científica interesse pela sexualidade humana. Desde então, vários estudos têm contribuído para uma melhor compreensão da resposta sexual na gravidez e puerpério. Neste artigo é efectuada uma revisão da literatura e uma reflexão sobre o conhecimento actual do tema.
