Sexually transmissible diseases, sexual factors and prostate cancer: A review of literature

A review of literature was carried out regarding sexually related factors, sexually transmissible diseases (STD's) and infections with prostate cancer (PC) development risk. The review of literature, in conjunction with the tabulation of studies, suggested that ejaculation and circumcision may play a protective role in the development of PC and that multiple sex partners and an active sex life may play a causal role in the development of PC which may negate and counteract the protective effects of ejaculation and circumcision. HIV infection may plausibly play a function in deteriorating and compromising immune controls on carcinogenesis. Because of the coexistence of a highly active sexual lifestyle and sexual promiscuity with the growing occurence of STD's, their maybe a correlation with the high incidence of prostate cancer in the United States. Potential multi-institutional studies are warranted to confirm the high incidence of this neoplasm with the increasing cases of STD's and if in fact there is a proportional association to further elucidate the factors responsible for its high incidence.^

Le modèle confluent de l'agression sexuelle appliqué à quatre paramètres de la carrière criminelle sexuelle

Ce mémoire consiste en une reproduction et une extension du Modèle Confluent de l’Agression Sexuelle (MCAS) de Neil Malamuth. Le MCAS est un des seuls modèles développementaux de l’agression sexuelle d’hommes sur des femmes adultes à avoir été validé empiriquement. Dans ce modèle, deux trajectoires (la promiscuité sexuelle et la masculinité hostile) convergent et mènent à l’agression sexuelle. Pour la première fois, ce modèle est appliqué séparément à quatre paramètres de la carrière criminelle sexuelle (gravité, fréquence, précocité, spécialisation) au sein d’un échantillon d’agresseurs sexuels de femmes adultes judiciarisés (n=180). Les quatre modèles qui en résultent s’ajustent bien aux données. Tous les liens postulés dans le MCAS sont validés dans ce mémoire, à une exception. En effet, contrairement aux résultats obtenus par Malamuth, une seule des deux trajectoires du modèle présente un lien significatif avec chacun des paramètres de la carrière criminelle sexuelle à l’étude. La trajectoire de la promiscuité sexuelle est liée à la précocité et à la non-spécialisation (lien négatif avec la spécialisation) alors que la trajectoire de la masculinité hostile est associée à la gravité et à la fréquence. Ces résultats sont congruents avec une approche typologique des agresseurs sexuels de femmes adultes. Chacune des deux trajectoires du MCAS englobe des caractéristiques spécifiques à certains types de violeurs (opportunistes, colériques, sadiques) qui, pour leur part, se distinguent quant aux paramètres de leur carrière criminelle sexuelle.

Efectividad del tratamiento farmacológico de la agresividad en pacientes con trastorno límite de la personalidad. Revisión sistemática

Introducción: el Trastorno Límite de la Personalidad afecta del 2% al 6% de los adultos en Estados Unidos. Es una condición de alta relevancia dentro de las patologías psiquiátricas debido a características como impulsividad, inestabilidad en las relaciones interpersonales, disregulación en el estado de ánimo y comportamiento agresivo. Esto determina un impacto negativo en la funcionalidad del individuo siendo la agresividad contra sí mismo o contra otras personas uno de sus componentes claves. Métodos: Revisión sistemática de la literatura de artículos de bases de datos y búsqueda manual de revistas relacionadas que aportaran la mejor evidencia con el fin de encontrar estudios que evaluaran, con instrumentos objetivos, los tratamientos farmacológicos disponibles para el manejo de la agresividad en el TLP .Se evaluó calidad metodológica y los estudios se organizaron en tablas de evidencia. Resultados: La búsqueda arrojo 1081 artículos de los cuales se seleccionaron 52 como potenciales y cinco fueron incluidos en esta revisión. Se clasificaron como nivel de evidencia Ib. El topiramato, el aripiprazol, el divalproato y la fluoxetina mostraron mejores resultados que el placebo especialmente en agresividad e impulsividad. El topiramato fue asociado con pérdida de peso. Los medicamentos fueron seguros y bien tolerados. Discusión: Los medicamentos evaluados mostraron ser mejores que placebo. La diversidad en las escalas utilizadas genera complejidad en la interpretación de resultados. Conclusión: La evidencia sugiere que el tratamiento farmacológico es efectivo en síntomas como agresividad e impulsividad comparado con placebo. Deben considerarse estudios que evalúen combinaciones de fármacos y psicoterapia.

Pulmonary tuberculosis: Hematology, serum biochemistry and the relation with the disease duration

The aim of the present study was to analyze the relationship between hematological and biochemical parameters and tuberculosis process activity time according to clinical complaint duration. It was a retrospective study analyzing medical records from 80 pulmonary tuberculosis patients at Botucatu Medical School University Hospital ( Botucatu, São Paulo State, Brazil), who were divided into 2 groups according to clinical complaint duration: Group 1 ( G1) - up to three months; Group 2 ( G2) - over three months. Parameters included: age, gender, bacilloscopy, erythrocyte sedimentation rate ( ESR), platelet count, alpha1-globulin, alpha2-globulin, gamma globulin, mucoprotein, alpha1-acid glycoprotein values, and the presence of risk factors such as smoking, alcoholism, drug addiction, sexual promiscuity, contact with tuberculosis carriers, and previous treatment. Groups were compared by calculating t and p, and Chi-square (X-2) and p. Comparisons revealed a tendency towards smoking with a higher frequency of smokers in G1 ( 0.05< p< 0.10). G1 also tended to present greater platelet values than G2 ( 0.05< p< 0.10) and presented significantly higher ESR values than G2 ( p< 0.05). Other factors did not show any significantly different behavior between groups ( p> 0.05). A correlation was found between ESR, platelet count, smoking and less than three months clinical duration.

Oral manifestations of secondary syphilis in the elderly - A timely reminder for dentists

Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum. Cases of syphilis have increased in frequency and are challenging when affecting the elderly. The main causes of increased prevalence of syphilis are sexual promiscuity, lack of knowledge about the disease and decreasing use of barrier protection. Clinically, the oral manifestation of syphilis may resemble other entities, which hampers the correct diagnosis. We report a case of a 79-year-old male with weight loss and feeding difficulties. In the oral cavity there were ulcerative lesions in the hard palate and bilaterally in the buccal mucosa. The incisional biopsy revealed only a non-specific ulceration of the oral mucosa. After 20 days, the patient was re-evaluated and presented maculopapular lesions in the palmar and plantar areas. Positive serological venereal disease reference laboratory (VDRL) tests confirmed the diagnosis of secondary syphilis. The patient was treated with Benzathine penicillin G. After two weeks of treatment the oral lesion disappeared and the patient returned to normal feeding and gained weight. This case report reinforces the need to alert physicians and dentists to include sexually transmitted infections such as syphilis in the differential diagnosis of oral ulcerative lesions in elderly sexually active patients. © 2013 Australian Dental Association.

Avaliação do programa de HIV/Aids na concepção dos usuários: o caso em um hospital de referência em Belém-PA

Estudo referente a avaliação do Programa de HIV/aids em um hospital de referência, na concepção dos usuários. O objetivo geral da pesquisa foi descrever a concepção dos usuários na unidade de internação e ambulatorial, sobre o programa de HIV/aids em um hospital universitário de referência na cidade de Belém-PA. Para o estudo foram traçados como objetivos específicos: apresentar as sugestões dos usuários do programa para a melhoria no desenvolvimento das atividades do programa e fornecer as ferramentas mínimas para a construção de um modelo de avaliação para o programa. No referencial foi utilizado o panorama da epidemia de HIV/AIDS, políticas de saúde no Brasil e a aids, e a avaliação de programas e serviços em saúde. O método e a abordagem foram qualitativo, descritivo do tipo estudo de caso. Foi utilizado um roteiro de entrevistas semi-estruturado sobre a temática. A pesquisa foi desenvolvida nas dependências do HUJBB, mais especificamente nos serviços do Programa de HIV/aids, em que foram entrevistados usuários do SAE e os internados na clínica de doenças infecto-parasitárias. Através da análise dos dados, foram divididas as falas em quatro categorias: caracterização do usuário quanto ao acesso ao serviço; a motivação do usuário pela qualidade do serviço; dificuldades frente às atividades e orientações do serviço; expectativas para a melhoria do programa. O resultado da pesquisa esclarece as restrições e qualidades do programa; a insatisfação do usuário no acesso ao serviço; o alto grau de motivação bem como a ausência da mesma; as principias dificuldades dos usuários em aderir as orientações e atividades do programa, como o medo de encarar a morte, a falta de recurso para chegar ao serviço, o preconceito vivido pelas pessoas com HIV/aids e a promiscuidade sexual; e as expectativas dos usuários para o programa: rapidez no atendimento, melhor infraestrutura. Conclui-se com as melhorias que podem contribuir para a qualidade de vida dos usuários, subsidiar demanda suficiente de profissionais para atender no programa e oferecer tratamento completo às pessoas que vivem com HIV/aids atendidas no programa do HUJBB.

Prevalence of the hepatitis C virus among university employees in São Paulo, southeastern Brazil: predictive factors and geoprocessing spatial analysis

Background There are limited studies on the prevalence and risk factors associated with hepatitis C virus (HCV) infection. Objective Identify the prevalence and risk factors for HCV infection in university employees of the state of São Paulo, Brazil. Methods Digital serological tests for anti-HCV have been performed in 3153 volunteers. For the application of digital testing was necessary to withdraw a drop of blood through a needlestick. The positive cases were performed for genotyping and RNA. Chi-square and Fisher’s exact test were used, with P-value <0.05 indicating statistical significance. Univariate and multivariate logistic regression were also used. Results Prevalence of anti-HCV was 0.7%. The risk factors associated with HCV infection were: age >40 years, blood transfusion, injectable drugs, inhalable drugs (InDU), injectable Gluconergam®, glass syringes, tattoos, hemodialysis and sexual promiscuity. Age (P=0.01, OR 5.6, CI 1.4 to 22.8), InDU (P<0.0001, OR=96.8, CI 24.1 to 388.2), Gluconergam® (P=0.0009, OR=44.4, CI 4.7 to 412.7) and hemodialysis (P=0.0004, OR=90.1, CI 7.5 – 407.1) were independent predictors. Spatial analysis of the prevalence with socioeconomic indices, Gross Domestic Product and Human Development Index by the geoprocessing technique showed no positive correlation. Conclusions The prevalence of HCV infection was 0.7%. The independent risk factors for HCV infection were age, InDU, Gluconergan® and hemodialysis. There was no spatial correlation of HCV prevalence with local economic factors.

The socio-cultural impact of the introduction of motorbike taxis in the rural community of Tombel, South West region, Cameroon

“The socio-cultural impact of the introduction of motorbike taxis in the rural community of Tombel, South West region, Cameroon” seeks to bring out the impact of commercial motorbike taxis on the lifestyle of the Bakossi. The principal objective of this research is to show how the introduction of motorbike taxis has modified the lifestyle of the Tombel population. This anthropological research defines the profile of a motorbike taxi rider, his role in society, the perception of the population towards this activity and the impact of this activity on the lifestyle of the rural population of Tombel. This study reveals that motorbike taxi riders are essentially made up of youths from all works of life who earn a living by riding a motorbike taxi on a daily bases for commercial purposes. The revenue earn here goes a long way to sustain the livelihood of the rider and his entourage, becoming an ascension tool into the social ladder. The activity is very dangerous not only for the riders buts also for the passengers because of the risks involved in riding for most of the riders do not have the basic knowledge of the road code. This research also reveals that motorbike taxi has become the preferred means of public transport of most inhabitants of Tombel to the point of monopolising certain destinations. The population of Tombel perceives this activity as an instrument of change that has brought development and progress. But this activity also constitutes a social ill because of the prevalent sexual promiscuity encouraged by the riders. This activity has also gotten a cultural impact on the society, changing perceptions and being involve in rituals. Motorbike taxis have become a force to reckon with in the organisation of the community. They are a “response from below” to the transport crises in Cameroon.

Physician attitudes on the HPV vaccine

The quadrivalent HPV vaccine was developed primarily for the prevention of cervical cancer. The vaccine, originally approved for females, was recently approved by the American Committee for Immunization Practices to be administered to males, allowing federal programs to pay for the vaccination for both males and females. However, uptake for this vaccination has been low. Studies show that physicians have great influence over whether or not parents decide to vaccinate their children. In this study, a survey was mailed out asking physicians about their attitude towards the HPV vaccination and what they believed to be the barriers to the vaccination of their patients. The analysis of the data included descriptive statistics and chi-square analysis in order to compare the differences in responses between male and female patients. The vast majority of physicians supported the vaccination of both females and males. However, the perceived barriers to vaccinating females differed from males, with physicians believing that parents' concern about sexual promiscuity was a greater barrier to vaccination in girls than boys (p=0.007). The other major significant difference in perceived barriers among physicians is the belief that physicians in general are less likely to promote the vaccination in males compared to females (p=0.01). Despite evidence to the contrary, it seems more patient education is needed regarding sexual promiscuity and its association with the HPV vaccine. There may also be a need for increased physician education regarding the use of the HPV vaccine for male patients.^

Populations with elevated mutation load do not benefit from the operation of sexual selection.

Theory predicts that if most mutations are deleterious to both overall fitness and condition-dependent traits affecting mating success, sexual selection will purge mutation load and increase nonsexual fitness. We explored this possibility with populations of mutagenized Drosophila melanogaster exhibiting elevated levels of deleterious variation and evolving in the presence or absence of male-male competition and female choice. After 60 generations of experimental evolution, monogamous populations exhibited higher total reproductive output than polygamous populations. Parental environment also affected fitness measures - flies that evolved in the presence of sexual conflict showed reduced nonsexual fitness when their parents experienced a polygamous environment, indicating trans-generational effects of male harassment and highlighting the importance of a common garden design. This cost of parental promiscuity was nearly absent in monogamous lines, providing evidence for the evolution of reduced sexual antagonism. There was no overall difference in egg-to-adult viability between selection regimes. If mutation load was reduced by the action of sexual selection in this experiment, the resultant gain in fitness was not sufficient to overcome the costs of sexual antagonism.

Sexual System, Sex Ratio, and Group Living in the Shrimp Thor amboinensis (De Man): Relevance to Resource-Monopolization and Sex-Allocation Theories

The sexual system of the symbiotic shrimp Thor amboinensis is described, along with observations on sex ratio and host-use pattern of different populations. We used a comprehensive approach to elucidate the previously unknown sexual system of this shrimp. Dissections, scanning electron microscopy, size-frequency distribution analysis, and laboratory observations demonstrated that T amboinensis is a protandric hermaphrodite: shrimp first mature as males and change into females later in life. Thor amboinensis inhabited the large and structurally heterogeneous sea anemone Stichoclactyla helianthus in large groups (up to 11 individuals) more frequently than expected by chance alone. Groups exhibited no particularly complex social structure and showed male-biased sex ratios more frequently than expected by chance alone. The adult sex ratio was male-biased in the four separate populations studied, one of them being thousands of kilometers apart from the others. This study supports predictions central to theories of resource monopolization and sex allocation. Dissections demonstrated that unusually large males were parasitized by an undescribed species of isopod (family Entoniscidae). Infestation rates were similarly low in both sexes (approximate to 11%-12%). The available information suggests that T. amboinensis uses pure search promiscuity as a mating system. This hypothesis needs to be formally tested with mating behavior observations and field measurements on the movement pattern of both sexes of the species. Further detailed studies on the lifestyle and sexual system of all the species within this genus and the development of a molecular phylogeny are necessary to elucidate the evolutionary history of gender expression in the genus Thor.

As lesbianidades entre o estigma da promiscuidade e da ilegitimidade sexual

This study approaches the ways that stigmas and stereotypes of lesbianity influence the sexuality realm of the lives of women who define themselves as lesbians. Basing on the gender and feminists studies, we questioned the legitimations of the heteronormativist society presented as arbitrary speeches about the lesbian existence - the promiscuity and the sexual illegitimacy. Starting from interviews in depth, we presented how the participants of the research (lesbian women) discourse regarding the construction of their subjectivations, through their life histories narratives. That research was financed by Fundação de Amparo à Pesquisa do Estado de São Paulo FAPESP, and accomplished by the Pos-Graduation Program of the Universidade Estadual Paulista Campus of Assis-SP.

Dna Extraction From Filter-paper Spots Of Vaginal Samples Collected After Sexual Violence.

To detect the presence of male DNA in vaginal samples collected from survivors of sexual violence and stored on filter paper. A pilot study was conducted to evaluate 10 vaginal samples spotted on sterile filter paper: 6 collected at random in April 2009 and 4 in October 2010. Time between sexual assault and sample collection was 4-48hours. After drying at room temperature, the samples were placed in a sterile envelope and stored for 2-3years until processing. DNA extraction was confirmed by polymerase chain reaction for human β-globin, and the presence of prostate-specific antigen (PSA) was quantified. The presence of the Y chromosome was detected using primers for sequences in the TSPY (Y7/Y8 and DYS14) and SRY genes. β-Globin was detected in all 10 samples, while 2 samples were positive for PSA. Half of the samples amplified the Y7/Y8 and DYS14 sequences of the TSPY gene and 30% amplified the SRY gene sequence of the Y chromosome. Four male samples and 1 female sample served as controls. Filter-paper spots stored for periods of up to 3years proved adequate for preserving genetic material from vaginal samples collected following sexual violence.

The Effect Of Pelvic Floor Muscle Training Alone Or In Combination With Electrostimulation In The Treatment Of Sexual Dysfunction In Women With Multiple Sclerosis.

Sexual dysfunction (SD) affects up to 80% of multiple sclerosis (MS) patients and pelvic floor muscles (PFMs) play an important role in the sexual function of these patients. The objective of this paper is to evaluate the impact of a rehabilitation program to treat lower urinary tract symptoms on SD of women with MS. Thirty MS women were randomly allocated to one of three groups: pelvic floor muscle training (PFMT) with electromyographic (EMG) biofeedback and sham neuromuscular electrostimulation (NMES) (Group I), PFMT with EMG biofeedback and intravaginal NMES (Group II), and PFMT with EMG biofeedback and transcutaneous tibial nerve stimulation (TTNS) (Group III). Assessments, before and after the treatment, included: PFM function, PFM tone, flexibility of the vaginal opening and ability to relax the PFMs, and the Female Sexual Function Index (FSFI) questionnaire. After treatment, all groups showed improvements in all domains of the PERFECT scheme. PFM tone and flexibility of the vaginal opening was lower after the intervention only for Group II. All groups improved in arousal, lubrication, satisfaction and total score domains of the FSFI questionnaire. This study indicates that PFMT alone or in combination with intravaginal NMES or TTNS contributes to the improvement of SD.
