Violência sexual como questão de saúde pública: importância da busca ao agressor

Apesar de predominar junto à população a idéia de que a violência sexual é praticada por pessoas desconhecidas, na realidade a maioria desses crimes é praticada por pessoa identificável pela vítima. Além de conseqüências físicas e psicológicas, também há risco em adquirir o vírus HIV. Para prevenção deste, em situação de risco, há orientação para uso da quimioprofilaxia anti-retroviral. Esse uso, por 28 dias, pode trazer efeitos adversos com intensidades variáveis. O conhecimento da sorologia anti-HIV do agressor torna-se fundamental para manter, ou suspender, com segurança, essa indicação. Este estudo descritivo, realizado no Conjunto Hospitalar de Sorocaba, teve como objetivo identificar os agressores e suas respectivas sorologias. Foi realizado a partir de fichas de notificação e os prontuários no período de julho de 2003 a dezembro de 2005. Encontraram-se 920 vítimas de violência sexual, com idades entre oito meses e 77 anos, havendo predomínio do sexo feminino (86,5 por cento). Dentre os agressores, 76 por cento foram referidos como identificáveis. Indicou-se profilaxia anti-retroviral para 24,9 por cento das vítimas. Para 80 (33,2 por cento) agressores localizados, a busca foi realizada através de contato telefônico. Encontrou-se 52,5 por cento em seus domicílios, 45 por cento em Presídio/Delegacia e 2,5 por cento no Pronto Socorro. Um agressor (1,3 por cento) apresentou sorologia positiva para HIV. As buscas encerraram-se, em sua maioria, em até seis dias (80 por cento), possibilitando a suspensão da quimioprofilaxia em 30,6 por cento dos casos. Concluiu-se que a busca ao denunciado permitiu conhecer sua sorologia anti-HIV e suspender, para um terço das vítimas, o uso da quimioprofilaxia anti-retroviral, diminuindo, com isso, a possibilidade de efeitos adversos

Compact tiled display with uniform illumination

The demand for more pixels is beginning to be met as manufacturers increase the native resolution of projector chips. Tiling several projectors still offers a solution to augment the pixel capacity of a display. However, problems of color and illumination uniformity across projectors need to be addressed as well as the computer software required to drive such devices. We present the results obtained on a desktop-size tiled projector array of three D-ILA projectors sharing a common illumination source. A short throw lens (0.8:1) on each projector yields a 21-in. diagonal for each image tile; the composite image on a 3×1 array is 3840×1024 pixels with a resolution of about 80 dpi. The system preserves desktop resolution, is compact, and can fit in a normal room or laboratory. The projectors are mounted on precision six-axis positioners, which allow pixel level alignment. A fiber optic beamsplitting system and a single set of red, green, and blue dichroic filters are the key to color and illumination uniformity. The D-ILA chips inside each projector can be adjusted separately to set or change characteristics such as contrast, brightness, or gamma curves. The projectors were then matched carefully: photometric variations were corrected, leading to a seamless image. Photometric measurements were performed to characterize the display and are reported here. This system is driven by a small PC cluster fitted with graphics cards and running Linux. It can be scaled to accommodate an array of 2×3 or 3×3 projectors, thus increasing the number of pixels of the final image. Finally, we present current uses of the display in fields such as astrophysics and archaeology (remote sensing).

STD syndrome packets: Improving syndromic management of sexually transmitted diseases in developing countries

Objective: To design, introduce, and evaluate STD syndrome packets containing recommended drugs for each syndrome, four condoms, a partner treatment card, and a patient information leaflet, with the goal of improving sexually transmitted disease (STD) case management. Methods: Packet design evolved around available packaging technology, informed by pilot testing with nurses working in primary care clinics, doctors in private medical practices, and patients with an STD, in Hlabisa, South Africa. Evaluation 1 year later included analysis of distribution records and interviews with 16 nurses and 61 patients. Results: A cheap packet (2 U, S, cents each, excluding contents) compatible with current legislation was designed and introduced to six public sector clinics and as a short pilot to five private medical practices, Four thousand eighty-five packets were distributed to the clinics, equivalent to approximately 115% of the STDs reported over that period. All 16 nurses reported using the packets, but only 63% did so all the time because of occasional supply problems, All believed the packets improved treatment by saving time (75%), improving supply of condoms and partner cards (44%), and making treatment easier (56%), Patients also responded positively, and most said they would buy a packet (up to $5) at a pharmacy (84%) or store (63%) if available. Conclusions: The STD syndrome packets have the potential to improve STD syndromic management by standardizing therapy and improving the supply of condoms, partner cards, and information leaflets. Packets are popular with practitioners and patients, but consistent supply is essential for maximal impact, There may be scope for social marketing of the packets, which could further increase use.

Morphology and histology of the spermathecal sac, a novel structure in the female reproductive system of Therevidae (Diptera : Asiloidea)

The reproductive system of many female Therevidae has a sac-like structure associated with the spermathecae. This structure, termed the spermathecal sac, has not been recorded previously from any other Diptera and appears unique to certain members of the Therevidae. There is enormous variety in spermathecal sac size and shape, with greatest development in the Australasian Therevidae. A histological examination of the reproductive system of two;Australian therevids, Agapophytus albobasalis Mann and Ectinorhynchus variabilis (Macquart) (Diptera: Asiloidea), reveals that the spermathecal sacs are cuticle-lined and that the intima is frequently highly folded. In some mated individuals, sperm was found within the spermathecal sac, suggesting that sperm and perhaps male accessory gland material is deposited there during copulation.

Syndrome packets and health worker training improve sexually transmitted disease case management in rural South Africa: randomized controlled trial

Background: Sexually transmitted diseases (STD) are important co-factors in HIV transmission. We studied the impact of health worker training and STD syndrome packets (containing recommended drugs, condoms, partner notification cards and information leaflets) on the quality of STD case management in primary care clinics in rural South Africa. Methods: A randomized controlled trial of five matched pairs of clinics compared the intervention with routine syndromic management. Outcomes were measured by simulated patients using standardized scripts, and included the proportion given recommended drugs; correctly case managed (given recommended drugs plus condoms and partner cards); adequately counselled; reporting good staff attitude; and consulted in privacy. Results: At baseline, the quality of STD case management was similarly poor in both groups. Only 36 and 46% of simulated patients visiting intervention and control clinics, respectively, were given recommended drugs. After the intervention, intervention clinics provided better case management than controls: 88 versus 50% (P < 0.01) received recommended drugs; 83 versus 12% (P < 0.005) were correctly case managed; 68 versus 46% (P = 0.06) were adequately counselled; 84 versus 58% experienced good staff attitude (P = 0.07); and 92 versus 86% (P = 0.4) were consulted privately. A syndrome packet cost US$1.50; the incremental cost was US$6.80. The total intervention cost equalled 0.3% of annual district health expenditure. Interpretation: A simple and affordable health service intervention achieved substantial improvements in STD case management. Although this is a critical component of STD control and can reduce HIV transmission, community-level interventions to influence health-seeking behaviour are also needed.

Does the tendency to act impulsively underlie binge eating and alcohol use problems? An empirical investigation

The co-occurrence of problem drinking and binge eating and purging has been well documented. However, there has been relatively little investigation of etiological models that may influence the development of this co-occurrence. This study tests the hypotheses that impulsivity is heightened in eating disordered women compared with controls, and that women with comorbid bulimia and alcohol use disorders show higher impulsivity than bulimic-only women. The Impulsivity scale, BIS/BAS scales, State Anxiety Inventory, and a behavioural measure of reward responsiveness (CARROT) were administered to 22 women with bulimia, 23 women with comorbid bulimia and alcohol abuse/dependence, and 21 control women. As hypothesised, eating disordered women scored higher than controls on several self-report measures of impulsivity and sorted cards faster during a financially rewarded trial on the behavioural task. Also, as predicted, comorbid women scored higher than bulimic women on the Impulsivity scale. These findings suggest that individual differences in impulsiveness and a tendency to approach rewarding stimuli may contribute to developing these disorders. (C) 2003 Elsevier Ltd.

Privacy and security enhanced offline oblivious transfer for massive data distribution

Unauthorized accesses to digital contents are serious threats to international security and informatics. We propose an offline oblivious data distribution framework that preserves the sender's security and the receiver's privacy using tamper-proof smart cards. This framework provides persistent content protections from digital piracy and promises private content consumption.

Influence of the CYP17 polymorphism on vasomotor symptoms in postmenopausal women: a pilot study

Objective To evaluate the influence of CYP17 polymorphism on menopausal symptoms after estrogen treatment. Methods A total of 130 women were recruited, but only 100 of these were selected according to inclusion and exclusion criteria; they were treated with 0.3 mg/day conjugated equine estrogens. One year later, the study was completed by 71 women. The analysis of the Kupperman menopausal index symptoms was made with information provided by the patients on daily diary cards. Blood samples were analyzed and the women were divided into two groups based on the CYP17, 5`-untranslated region: group A (wild-type homozygote and heterozygote) and group B (mutated homozygote). Results The values for the Kupperman menopausal index were similar in both groups at baseline. The symptoms in both groups decreased after 1 year of treatment when compared to those at baseline. The improvement rate was approximately 27.09% and 32.18%, in groups A and B, respectively. The levels of estrogen after treatment were higher in both groups in comparison with the baseline values. The testosterone level rose in group B with the 1-year treatment (0.48 +/- 0.16 ng/ml), reaching a higher level than the level in group A after treatment. The sex hormone binding globulin (SHBG) level showed a significant increase after the 1-year treatment in group B, surpassing both the baseline and the after-treatment values in group A (p < 0.01). Conclusion Our data suggest that the CYP17 polymorphism did not influence the action of estrogen on menopause symptoms during the 1-year treatment. The extra production of estrogen and androgen may have been countered by the elevation of SHBG levels.

Chromoblastomycosis: study of 27 cases and review of medical literature

BACKGROUND: Chromoblastomycosis is a subcutaneous mycosis that occurs mainly in rural workers although is being more commonly found among people working in other sectors. The fungus penetrates the skin after its inoculation and the most frequently isolated agent is the Fonsecaea pedrosoi. OBJECTIVES: This study aims at evaluating patients suffering from chromoblastomycosis admitted into the Department of Dermatology of the University Hospital of the Faculty of Medicine of Sao Paulo State during the ten-year period from 1997 to 2007. METHODS: It is a retrospective study and the medical report cards of 27 Brazilian patients diagnosed as suffering from Chromoblastomycosis from 1997 to 2007 at the Dermatology Department of the Medical School, University of Sao Paulo were reviewed. The following items were analyzed: previous therapeutic approaches; treatment implemented by the group; length of time between the appearing of the lesion and diagnosis; age; gender; profession; origin; site of lesions; isolated agents found in culture and histopathology. RESULTS: Twenty two patients were from the state of Sao Paulo whereas the others came from the states of Bahia and Rondonia. 37% of them were rural workers. Men were more frequently infected (85%). Lesions were more commonly found on the lower limbs (59.2%). In 52% of the cases the isolated agent was the dematiaceous fungus Fonsecaea. pedrosoi. Biopsies showed sclerotic bodies in 92.5% of the cases. CONCLUSION: Data found are in accordance with medical literature on the subject. The disease had been previously studied in our institution in 1983 by Cuce et al. This present study is the second retrospective one about the characteristics of patients suffering from chromoblastmycosis which has been published in indexed medical literature in the state of Sao Paulo.

The ultrastructure and function of the silk-producing basitarsus in the Hilarini (Diptera : Ernpididae)

The tribe Hilarini (Diptera: Empididae), commonly known as dance flies, can be recognised by their swollen silk-producing prothoracic basitarsus, a male secondary sexual characteristic. The ultrastructure and function of the silk-producing basitarsus from one undescribed morphospecies of Hilarini, 'Hilarempis 20', is presented. Male H. 20 collect small parcels of diatomaceous algae from the surface of freshwater creeks that they bind with silk produced by the gland in the basitarsus. The gift is then presented to females in a nearby swarm, composed predominately of females. The basitarsus houses approximately 12 pairs of class III dermal glandular units that congregate on the ventral side of the cavity. Each gland cell has a large extracellular lumen where secretion accumulates. The lumen drains to the outside via a conducting canal encompassed by a canal cell and a duct extending through the shaft of a specialised secretory spine. The secretory spines lie in pairs in a ventral groove that runs the length of the basitarsus. A comparison of the basitarsal secretory spines with sensilla on the basitarsi of non gland-bearing legs of males, and with non gland-bearing prothoracic. basitarsi of females, suggests that the glandular units are derived from contact chemosensory sensilla.

Ação transovariana de lufenuron (50 g/l) sobre adultos de Spodoptera Frugiperda (j. e. smith) (Lepidoptera: Noctuidae) e seu efeito sobre o parasitóide de ovos Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae)

Avaliaram-se a ação transovariana do lufenuron em Spodoptera frugiperda e sua seletividade ao parasitóide de ovos Trichogramma pretiosum. Casais da praga foram isolados em gaiolas de PVC e alimentados com solução de mel a 10% na testemunha, e nos outros tratamentos, foi adicionado à solução de mel o regulador de crescimento de insetos Match® CE nas proporções de 12,5; 15,0 e 17,5 g i.a/l. Para verificação da ação transovariana, diariamente foram coletadas as posturas, contado o número de ovos e, posteriormente, o número de larvas eclodidas. Quarenta ovos provenientes de cada tratamento foram colados em cartelas de papel (cartolina) e expostos ao parasitismo, dentro de tubos de vidro de 1,0 x 3,5 cm, contendo uma fêmea de T. pretiosum no seu interior. Cartelas contendo 40 ovos de S. frugiperda foram imersas em soluções de lufenuron com a mesma concentração dos tratamentos anteriores e, posteriormente, expostas ao parasitismo por T. pretiosum. O lufenuron afetou consideravelmente a viabilidade dos ovos de S. frugiperda. Pelos resultados obtidos nos ensaios, relativos ao parasitóide, demonstram-se a seletividade do regulador de crescimento lufenuron e a possibilidade de sua utilização em programas de Manejo Integrado, juntamente com o parasitóide de ovos T. pretiosum.

Vendas de bebidas alcóolicas : questões (im)pertinentes

O objetivo deste estudo é analisar a disponibilidade e o acesso à bebida alcoólica num bairro da cidade de Vitória/ES. Os dados foram obtidos através de pesquisa de campo na região selecionada utilizando a observação simples e a entrevista através da aplicação de questionários numa amostra de 10% dos estabelecimentos encontrados. Os pontos de venda funcionam 7 dias por semana; 68,8% vendem a credito e a um preço médio de R$ 0,41 (a dose de cachaça). 93,8% dos entrevistados não solicitam documento de identidade ao cliente antes de lhe vender bebidas. A relação entre número de moradias e número de pontos de venda foi de 3:1. A alta concentração de estabelecimentos que vendem bebidas alcoólicas no bairro aponta para a necessidade de pensar o entorno (regiões vizinhas) da mesma. Estas regiões envolvem áreas marginalizadas onde ocorre tráfico de drogas, fazendo da região estudada uma área importante para o comércio, pela facilidade de acesso aos outros bairros adjacentes da cidade.

Benzedeiras de Maruípe: uma prática de cuidado humano em extinção

Estudo realizado com benzedeiras de uma área de saúde do município de Vitória - ES, objetivando identificá-las, conhecer suas histórias de vida e o interesse das mesmas em articularem-se com os profissionais das unidades básicas de saúde locais. Por se tratar de uma região marcada pela violência advinda do tráfico de drogas, tornou-se impossível identificar o universo dessas mulheres, face à impossibilidade de acesso a alguns desses bairros; assim posto, nossa amostra ficou limitada a cinco benzedeiras. A coleta de material do estudo se deu através de entrevistas e observações registradas em um diário de campo. O material transcrito e os apontamentos do diário de campo possibilitaram a narrativa de inspiração cartográfica deste estudo. Essas benzedeiras são mulheres entre 64 a 88 anos de idade, residem em locais inóspitos e em moradias humildes. Algumas benzem apenas crianças, outras todos aqueles que as procuram, inclusive para benzimento de seus animais. Nenhuma delas cobra e tão pouco aceita agradecimento pela atenção prestada, pois segundo elas, o agradecimento deve ser dirigido a Deus. São mulheres humildes, todas moradoras antigas da área, ora reconhecidas como importantes pelo dom que têm, ora rechaçadas como demoníacas por grupos religiosos. No tocante a uma aproximação com as equipes locais de saúde, todas as benzedeiras se mostraram avessas à ideia, no entendimento de que tal aproximação significaria uma demanda de benzimentos aumentada e obrigatória, o que contraria a lógica da atenção prestada pelas mesmas, que só benzem de acordo com a conveniência: sentindo-se bem, praticam o benzimento; estando desvitalizadas, evitam benzer. Por se tratar de mulheres idosas, as benzedeiras encontram-se ameaçadas de extinção, visto que aprender o oficio não tem sido objeto de interesse das novas gerações.

Para uma sócio-história da língua Guarani no Espírito Santo : uma análise sob a perspectiva sociolinguística

Estima-se que restam hoje cerca de 50 mil índios Guarani no Brasil, que se situam, principalmente, na faixa litorânea que vai desde os estados do sul até o território capixaba, o Espírito Santo. Considerando que essa comunidade se mantém bilíngue, o presente trabalho objetiva discutir se, na situação de contato entre o Guarani e o Português, a primeira língua está ou não cedendo lugar à segunda. Para alcançar esse objetivo, foi formado um banco de dados de fala por meio de entrevistas realizadas nas aldeias, que versaram sobre as tradições históricas, a família, a religião, a economia e o meio ambiente – aspectos considerados por eles como as principais armas de resistência desse povo. A análise tomou por base os pressupostos da Sociolinguística/Contato Linguístico, com teóricos como Weinreich (1953), Fishman (1968; 1972), Appel e Muysken (1996), Coulmas (2005) e outros, que discutem temas pertinentes à pesquisa em questão: o contato linguístico e a manutenção/substituição de línguas minoritárias. Acredita-se que, apesar do contato com o português pela venda de artesanatos, pela mídia e pela atuação da escola e sua ação integralizadora, prevista pelo Estatuto do Índio, o Guarani mantém a sua língua materna - ainda que estigmatizada - devido à forte religiosidade que norteia todo o seu modo de vida. Ele entende a palavra como um dom e confere a ela um poder mítico de conexão com o mundo espiritual, o que, ao mesmo tempo, confere extrema importância à língua minoritária e favorece a sua preservação, enquanto marca importante da cultura e identidade desse povo.
