ABSTRACT

ABSTRACT Background: Non-metastatic castration resistant prostate cancer (M0 CRPC) has seen important developments in drugs and diagnostic tools in the last two years. New hormonal agents have demonstrated improvement in metastasis free survival in M0 CRPC patients and have been approved by regulatory agencies in Brazil. Additionally, newer and more sensitive imaging tools are able to detect metastasis earlier than before, which will impact the percentage of patients staged as M0 CRPC. Based on the available international guidelines, a group of Brazilian urology and medical oncology experts developed and completed a survey on the diagnosis and treatment of M0 CRPC in Brazil. These results are reviewed and summarized and associated recommendations are provided. Objective: To present survey results on management of M0 CRPC in Brazil. Design, setting, and participants: A panel of six Brazilian prostate cancer experts determined 64 questions concerning the main areas of interest: 1) staging tools, 2) treatments, 3) side effects of systemic treatment/s, and 4) osteoclast-targeted therapy. A larger panel of 28 Brazilian prostate cancer experts answered these questions in order to create country-specific recommendations discussed in this manuscript. Outcome measurements and statistical analysis: The panel voted publicly but anonymously on the predefined questions. These answers are the panelists' opinions, not a literature review or meta-analysis. Therapies not yet approved in Brazil were excluded from answer options. Each question had five to seven relevant answers including two non-answers. Results were tabulated in real time. Conclusions: The results and recommendations presented can be used by Brazilian physicians to support the management of M0 CRPC patients. Individual clinical decision making should be supported by available data, however, for Brazil, guidelines for diagnosis and management of M0 CRPC patients have not been developed. This document will serve as a point of reference when confronting this disease stage.

ABSTRACT

This letter to the Editor aims to provide suggestions and recommendations for the management of urological conditions in times of COVID-19 crisis in Brazil and other low- and middle-income countries. It is important to highlight that one of the main characteristics of this pandemic is the oversaturation of the health system capacity, mostly due to a high demand for personal protective equipment (PPE), Hospital/ICU beds, as well as ventilators. In places with limited resources and where the health care systems are already saturated, such consideration is even more worrisome. Therefore, most worldwide authorities are recommending to avoid, as much as possible, patient's elective visits to hospitals, as well as a judicious use of the operating room in order to mitigate the strain put on the health system. While efforts should be directed to the care of COVID-19 patients, other conditions (especially urgencies and oncological cases) must continue to be assisted. Thus, through a panel of experts, we have prepared a practical guide for urologists based on the recommendations from the main Urologic Associations, as well as data from the literature to support the suggested management. We will try to follow the standard guideline recommendations from the American Urological Association (AUA) and European Association of Urology (EAU), with the aim of pursuing the best outcomes possible. However, some recommendations were based on the consensus of the panel, taking into consideration the reality of developing countries and the unprecedented situation caused by the COVID-19 crisis. Most importantly, all recommendations on this manuscript are based on the expectancy of a maximum 3-month duration of the crisis. If this period shall extended, these recommendations will be revised and updated. The format of the text will be given through questions and answers.(AU)

ABSTRACT

Resumo Objetivo: O objetivo do presente estudo foi desenvolver uma metodologia que aproxime o discente do conteúdo abordado nas aulas de anatomia do globo ocular. Métodos: Foi realizada uma incisão circular na lâmina orbital do osso frontal de um cadáver humano de uma instituição em saúde e, para acessar as estruturas orbitárias, foram dissecadas as estruturas da área criando uma via para a injeção de uma solução de borracha de silicone branca entre o cristalino e a retina com posterior enucleação e dissecação final. Resultados: O emprego da técnica permitiu que os discentes do curso construíssem o conhecimento tátil do órgão em questão e transformando o saber teórico em prático, reconhecendo músculos, funcionalidade, vasos sanguíneos e estruturas oculares durante o procedimento de dissecação. Conclusão: A metodologia empregada no presente estudo é uma opção viável para o ensino da anatomia do olho.


Abstract Objective: The objective of the present study was to develop a methodology that approximates the student of the content addressed in the classes of anatomy of the eyeball. Methods: A circular incision was made in the orbital blade of the frontal bone of a human cadaver of a health institution and, to access the orbital structures, the area structures were dissected creating a pathway for the injection of a solution of white silicone rubber between the lens and the retina with subsequent enucleation and final dissection. Results: The use of the technique allowed the students of the course to construct the tactile knowledge of the organ in question and transform the theoretical knowledge into practice, recognizing muscles, functionality, blood vessels and ocular structures during the dissection procedure. Conclusion: The methodology used in the present study is a viable option for teaching the anatomy of the eye.

ABSTRACT

ABSTRACT This study aimed to determine the histological features of the endometrium of bitches, as well as the cell proliferation at specific moments of diestrus, 10, 20, 30, 40, 50 and 60 days post ovulation, correlating the endometrial thickness with the uterine cell proliferation and the metabolic state (weight, blood glucose and plasma cholesterol) of the animals. Therefore, the right and left uterine horns of 26 clinically healthy bitches submitted to ovariohysterectomy were histologically analyzed 10, 20, 30, 40, 50 and 60 days post ovulation. The hematoxylin-eosin and AgNOR staining techniques were performed. All parameters were evaluated by ANOVA and post-hoc Tukey test (p<0.05). The correlation between endometrial thickness and uterine cell proliferation, weight, blood glucose and plasma cholesterol of animals was observed using the Pearson method (p<0.05). In the present study, it is concluded that endometrial thickness does not differ at any of the moments analyzed in diestrus. The endometrial thickness is not influenced by hormones, weight, blood glucose or serum cholesterol of bitches in this phase of the estrous cycle. However, there is greater cell proliferation in the endometrium at day 40 compared to day 60 post ovulation under the influence of the endocrine profile.

ABSTRACT

The use of Pilates-based exercises for trunk strengthening has been reported in the literature. The objective of this study was to analyze and compare the electrical activity of the rectus abdominis and external oblique muscles during a traditional abdominal exercise program and an exercise program based on the Pilates method using a ball and an elastic band. The sample was composed of 10 healthy women, non-practitioners of Pilates, who performed the traditional abdominal exercise and roll-up with the ball and elastic band. The sign was normalized by the electromyographic peak of the dynamic activity and was adjusted for 2000 samples/s; the filter was set in a frequency band from 20 to 450 Hz. In the comparison between exercises, the external oblique muscle in the concentric phase had a higher recruitment in the roll-up with the ball (P = 0.042). In the comparison between muscles in each exercise, the rectus abdominis showed a higher activation in the concentric phase (P = 0.009) and in the eccentric phase (P = 0.05) of the traditional abdominal exercise. Activation percentages ranged from 15% to 22%. The traditional abdominal exercise had the largest activation percentage.


Exercícios baseados no método Pilates são relatados na literatura para serem utilizados como proposta de fortalecimento de tronco. O objetivo deste estudo foi analisar e comparar a atividade elétrica dos músculos reto abdominal e oblíquo externo, durante um exercício de abdominal tradicional e um exercício baseado no método Pilates com bola e com faixa elástica. A amostra foi composta por 10 mulheres saudáveis não praticantes de Pilates, que realizaram o exercício de abdominal tradicional e Roll-up com bola e faixa elástica. O sinal foi normalizado pelo pico eletromiográfico da atividade dinâmica e foram ajustados para 2000 amostras por segundo e o filtro em uma frequência de passagem de 20 a 450 Hz. Na comparação entre exercícios, o músculo oblíquo externo na fase concêntrica teve maior recrutamento no Roll-up com bola (P = 0,042). Na comparação entre os músculos em cada exercício, o reto abdominal teve maior ativação nas fases concêntrica (P = 0,009) e excêntrica (P = 0,05) do abdominal tradicional. As porcentagens de ativação variaram de 15% a 22%. O exercício de abdominal tradicional teve a maior porcentagem de ativação.

ABSTRACT

A gravidez na adolescência está associada a diversos problemas físicos, sociais e emocionais que revelam um importante problema de Saúde Coletiva. Nos últimos anos, vários estudos têm reportado que a gravidez na adolescência pode trazer consequências negativas tanto para a mãe quanto para o bebê. O presente trabalho teve por objetivo avaliar o perfil de gestantes adolescentes atendidas no Programa da Saúde da Família (PSF) 302 da cidade de Aragarças, GO. Foram avaliadas 54 gestantes na faixa etária de 15 a 40 anos. O método utilizado foi o de entrevista com questionário contendo perguntas relacionadas à vida pessoal da mãe, à gravidez, além dos fatores associados à ocorrência da gestação. Observou-se que 18% das gestantes eram adolescentes, destas 40% foram reincidentes e 30% solteiras. Entre as adolescentes, 88% não exerciam atividades remuneradas e estavam com as atividades escolares comprometidas. Quando se avaliou o índice de gravidez não planejada, 75% relataram não ter planejado a gravidez. Esses dados reforçam a falta de educação sexual e planejamento familiar entre as jovens residentes na cidade de Aragarças (Goiás), indicando, assim, a necessidade de programas de prevenção de gravidez na adolescência.


Adolescent pregnancy is associated with various physical, social, and emotional problems and is currently considered an important public health problem. In recent years, a number of studies have been reporting that adolescent pregnancy can carry negative consequences for both the mother and the baby. The aim of this study was to evaluate the profile of pregnant adolescents treated at the Family Health Program (PSF) 302 in the city of Aragarças, GO. The assessment included 54 women with ages from 15 to 40 years. The method used was an interview including a questionnaire about the mother?s personal life, the pregnancy process, and its associated factors. It was observed that 18% of the pregnant women were adolescents, 40% of these were pregnancy re-incident, and 30% were single. Among the adolescents, 88% did not have paid employment and their school activities had been compromised. In evaluating the unplanned pregnancy rate, 75% of these adolescent or adult women reported not having planned the pregnancy. These findings suggest a lack of sex education and family planning among the younger residents of the city of Aragarças (Goiás), thus indicating the urgent need for adolescent pregnancy prevention programs.

ABSTRACT

Nos últimos 40 anos, o perfil mundial do câncer vem mudando. Encarado inicialmente como uma doença dos países ricos, nota-se atualmente que a maior parte de seu ônus global provêm de países de poucos recursos ou em desenvolvimento. Nas últimas décadas o câncer se tornou um problema de saúde pública mundial, com estimativas alarmantes para as décadas subseqüentes. No Brasil, as estimativas para o ano de 2012 serão válidastambém para o ano de 2013 e revelam a ocorrência de aproximadamente 518.510 casos novos de câncer,incluindo os casos de pele não melanoma. São esperados um total de 257.870 casos novos para o sexo masculino. A grande questão é que cerca de 10% destes casos serão na faixa etária inferior a 45 anos e 1% abaixo de 20 anos de idade. Embora o tratamento atual do câncer tenha aumentado consideravelmente as taxas de sobrevida em 5 anos de pacientes jovens, ele quase que invariavelmenteestará associado a enorme risco de infertilidade, levando a impacto negativo importante na vida destes jovens homens. Este artigo de revisão aborda os mais atuais conceitos empreservação de fertilidade em homens jovens tratados de câncer, o crescimento deste campo dentro da oncologia e da urologia e o futuro deste tema tão relevante para nossapopulação. Até hoje existe uma importante desconexão entre os guidelines mundiais e a prática médica, quando o assunto é preservação da fertilidade em homens com câncer em idade reprodutiva...


Over the past 40 years, the global profile of cancer is changing. Initially regarded as a disease of the richcountries, it is noted that currently most of its global burden comes from poor or developing countries. In recent decades cancer has become a public health problem worldwide, withalarming estimates for subsequent decades. In Brazil, the estimates for the year 2012 will be valid for the year 2013 and reveals the occurrence of approximately 518,510 new cases of cancer, including cases of non-melanoma skin. Are expected a total of 257,870 new cases for males. The greatthing is that about 10% of these cases are in the age group below 45 years and 1% below 20 years of age. Although the current treatment of cancer has increased considerablysurvival rates at 5 years young patients, it is almost invariably associated with great risk of infertility, leading to significant negative impact in the lives of these young men. This review article discusses the most current concepts in preserving fertility in young men treated for cancer, thegrowth of this field within the oncology and urology and the future of this topic so relevant to our population. Eventoday there is a important disconnect between the world and medical practice guidelines, when it comes to fertility preservation in men with cancer of reproductive age...

ABSTRACT

OBJECTIVE: Evaluate the Glasgow outcome scale (GOS) at discharge (GOS-HD) as a prognostic indicator in patients with traumatic brain injury (TBI). METHOD: Retrospective data were collected of 45 patients, with Glasgow coma scale <8, age 25±10 years, 36 men, from medical records. Later, at home visit, two measures were scored: GOS-HD (according to information from family members) and GOS LATE (12 months after TBI). RESULTS: At discharge, the ERG showed: vegetative state (VS) in 2 (4%), severe disability (SD) in 27 (60%), moderate disability (MD) in 15 (33%) and good recovery (GR) in 1 (2%). After 12 months: death in 5 (11%), VS in 1 (2%), SD in 7 (16%), MD in 9 (20%) and GR in 23 (51%). Variables associated with poor outcome were: worse GOS-HD (p=0.03), neurosurgical procedures (p=0.008) and the kind of brain injury (p=0.009). CONCLUSION: The GOS-HD was indicator of prognosis in patients with severe TBI.


OBJETIVO: Avaliar a escala de resultados de Glasgow (ERG) à alta hospitalar (ERG-ALTA) como indicador prognóstico em pacientes com traumatismo cranioencefálico (TCE). MÉTODO: Dados retrospectivos de 45 pacientes (36 homens), com escala de coma de Glasgow <8, idade 25±10 anos, foram coletados do prontuário médico. Posteriormente, em visita domiciliar, foram pontuadas duas medidas: ERG-ALTA (de acordo com informações de familiares) e ERG TARDIA (após 12 meses do TCE). RESULTADOS: Por ocasião da alta hospitalar, a ERG evidenciou: estado vegetativo (EV) em 2 (4%); incapacidade grave (IG) em 27 (60%), incapacidade moderada (IM) em 15 (33%) e boa recuperação (BR) em 1 (2%). Após 12 meses: morte em 5 (11%), EV em 1 (2%), IG em 7 (16%), IM em 9 (20%) e BR em 23 (51%). Variáveis associadas com má evolução foram: pior ERG-ALTA (p=0,03); procedimentos neurocirúrgicos (p=0,008) e o tipo de lesão cerebral (p=0,009). CONCLUSÃO: A ERG-ALTA foi indicador adequado de prognóstico tardio em pacientes com TCE grave.

ABSTRACT

O presente artigo aborda os aspectos clínicos e socioeconômicos decorrentes da presença de dislipidemias em portadores de doenças cardiovasculares (DCV). Existem inúmeros estudos relacionados às DCV, uso de hipolipemiantes orais como as estatinas, e os aspectos econômicos envolvidos com impacto na área da saúde. Além de evidenciar a importância do tratamento das dislipidemias, o artigo busca demonstrar o ponto de vista farmacoeconômico, ou seja, dos custos gerados com o tratamento farmacológico desta patologia versus os custos decorrentes dos eventos cardiovasculares acometidos e suas consequências. Existe, portanto, relevante relação entre os impactos sociais decorrentes de incapacidade física e laborativa, aposentadorias precoces, entre outros custos importantes que poderiam ser evitados com uma análise econômica abrangente e eficiente realizada nos serviços de saúde do Brasil. Neste contexto, é enfatizada a importância da análise conjunta dos aspectos clínicos e socioeconômicos das dislipidemias que poderiam influenciar nas decisões das autoridades de saúde no momento da elaboração de protocolos clínicos de tratamentos farmacológicos a serem implementados no SUS.


This paper discusses the clinical and socioeconomic factors arising from the presence of dyslipidemia in patients with cardiovascular disease (CVD). There are numerous studies related to CVD, oral use of statins as statins, and the economics aspects involved with an impact on health. In addition to demonstrating the importance of the treatment of dyslipidemia, the paper shows the pharmacoeconomic viewpoint, i.e. costs generated by the pharmacological treatment of this disease versus the costs of cardiovascular events and their consequences. There is therefore relevant relationship between the social impacts arising from physical disability and work, early retirements, among other important costs that could be avoided with a comprehensive economic analysis and efficient health services in Brazil. In this context, we emphasize the importance of joint analysis of the clinical and socioeconomic aspects of dyslipidemia that could influence the decisions of health authorities at the time of preparation of clinical protocols of pharmacological treatments to be implemented within the SUS.

ABSTRACT

The sternocleidomastoid is a muscle with a great extension that occupies the cervical region and is extended obliquely from the head to the trunk. Its morphology is not uniform, once its ends are wide and slim while its medial edge is thick and narrow. The aim of our work was to relate a case of variation in clavicular origin of this muscle that was extended beyond the half of clavicle laterally, in both sides of the neck.


El esternocleidomastóideo es un músculo de gran extensión en la región cervical con trayecto oblicuo desde la cabeza hasta el tronco. Su morfología no es uniforme, debido a que sus extremos son anchos y finos, mientras que él es grueso y estrecho en su borde medial. El objetivo de este trabajo fue relatar un caso de la variación en el origen clavicular de este músculo que se extendí mas allá de la mitad de la clavícula en dirección lateral, en ambos lados del cuello.

ABSTRACT

A partir de uma pesquisa acerca de produções acadêmicas referentes à temática abrigamento, objetivando cartografar subjetividades construídas dentro de abrigos, analisamos textos (livros, artigos, dissertações e teses), no período de 2000 a 2008 referentes a essa temática. Debruçamo-nos sobre esse material com a finalidade de dar visibilidade aos discursos/práticas que estão sendo produzidos, traçando um breve histórico das medidas de assistência e proteção à infância e à juventude brasileiras. A partir do conteúdo dos textos foram levantadas diferentes categorias de análise, porém aqui estamos priorizando os debates relativos a uma delas: "Rede de Assistência ao Abrigo". Tomando o referencial da Análise do Discurso, o presente artigo problematiza as redes de proteção das políticas públicas de garantia dos direitos da criança e do adolescente. Constatamos que, grande parte dos textos estudados mencionava a fragilidade das redes de proteção como responsáveis pela permanência de crianças e adolescentes em abrigos.


From a research on academic productions related to housing issues, aiming to map subjectivities constructed in shelters, we analyzed texts (books, articles, theses and dissertations) about the issue from the period between 2000 and 2008. We studied the material carefully in order to give visibility to the discourses and practices that are being produced, outlining a brief history of assistance and protection measures to children and youth in Brazil. From the content of the texts were raised different categories of analysis, but here we have decided to focus on the discussions about one of them: "Network of Shelter Assistance". Taking the reference of the Speech Analysis, this article analyses the protection networks from the public policies which guarantee the rights of children and adolescents. We noticed that most studied texts mentioned the fragility of these networks as responsible for the protection and retention of children and adolescents in shelters.

ABSTRACT

Indivíduos com dor lombar têm redução na força e na resistência dos músculos paraespinhais. A avaliação da fadiga e da resistência dos músculos paraespinhais é importante, uma vez que tem sido reportado que indivíduos com lombalgia desenvolvem um déficit no condicionamento físico que influencia na força e na função do tronco. Além disso, ainda é incerto a relação da fadiga dos paraespinhais e o ângulo de flexão anterior de tronco. Os objetivos deste estudo foram comparar a fadiga em indivíduos com e sem dor lombar e correlacionar a fadiga com o ângulo de flexão anterior de tronco. O grupo lombalgia foi composto por dez indivíduos com diagnóstico médico exclusivo de lombalgia. O grupo controle foi composto por dez indivíduos que possuíam características físicas semelhantes. Inicialmente avaliou-se a flexão anterior de tronco dos indivíduos pelo método angular de Whistance. A fadiga dos músculos paraespinhais foi avaliada nas alturas de L1 e L5 por meio da eletromiografia de superfície em duas cargas: 50 e 75 por cento da contração isométrica voluntária máxima. Os resultados do estudo indicaram que o grupo lombalgia apresentou menor força durante os testes de contração isométrica voluntária máxima (P < 0,004). Embora o grupo lombalgia tenha apresentado maior valor de fadiga, não houve diferença estatisticamente significante entre os dois grupos para as alturas de L1 e L5 nas duas cargas. As correlações entre a fadiga e o ângulo de flexão anterior de tronco mostraram-se de fracas a moderadas (valores entre r = -0,58 a 0,51). Estes achados indicam que ambos os grupos fadigam, entretanto o grupo lombalgia apresentou maior fadiga. Além disso, não se pode predizer a fadiga por meio do ângulo de flexão anterior de tronco.


Subjects with low back pain have reduction in strength and endurance of the erector spinae muscles. The assessment of the fatigue and the endurance of these muscles is important, once it has been reported that individuals with low back pain develop a deficit in physical conditioning which influences on trunk strength and function. Moreover, the relationship between back muscles fatigue and trunk forward flexion is still unclear. The aims of this study were to compare fatigue between individuals with and without low back pain and to correlate the muscles fatigue with the angle of trunk forward flexion. The low back pain group consisted of ten low back pain subjects. The control group was composed by ten subjects with similar physical characteristics and without low back pain. Initially, the trunk forward flexion was evaluated with the Whistance angular method. The erector spinae fatigue was assessed at L1 and L5 by surface electromyography on two loads: 50 and 75 percent of maximal voluntary isometric contraction. The results indicated that the low back pain group presented a lower strength output during maximal voluntary isometric contraction (P < 0.004). Although the low back pain group has presented greater values of fatigue, there is no statistically significant difference between groups at L1 and L5. The correlation between muscles fatigue and trunk forward flexion angle have shown poor to moderate values (between r = -0.58 to 0.51). The results suggest that both groups present fatigue, however the low back pain group presented greater values. Moreover, it is not possible to predict fatigue by analysis of the trunk forward flexion angle.

ABSTRACT

INTRODUÇÃO: Pacientes com lesão cerebral grave (LCG) ou com morte encefálica (ME) freqüentemente apresentam alterações na secreção de vasopressina (AVP). OBJETIVO: Avaliar os níveis séricos de AVP em pacientes com LCG e ME. DESENHO: Estudo prospectivo, aberto, observacional. LOCAL: Um hospital geral universitário. MÉTODO: Sujeitos adultos (idade >18 anos), de ambos os sexos, foram divididos em três grupos: grupo controle: 29 voluntários sadios; grupo LCG: 17 pacientes com pontuação na Escala de Coma de Glasgow (ECG)<8; grupo ME: 11 pacientes com diagnóstico de ME. Amostras de sangue venoso foram colhidas pela manhã, em repouso, nos pacientes do grupo controle, e de 8/8h, por 24h, nos pacientes dos grupos LCG e ME, para dosagens de AVP. Variáveis clínicas e laboratoriais de interesse foram anotadas concomitantemente. RESULTADOS: Os valores da AVP (pg/ml) foram [média (DP); mediana]: grupo controle [2,2(1,1); 2,0]; grupo LCG [5,7(6,3); 2,9] e grupo ME [2,6(1,0); 2,8]. Observou-se maior variação dos níveis séricos de AVP no grupo LCG, mas sem diferença estatisticamente significativa em relação aos demais (p=0,06). Hipotensão (p=0,02), hipernatremia (p=0,0001), hiperosmolaridade sérica (p=0,0001) e hiposmolaridade urinária (p=0,003) foram proeminentes no grupo ME em relação ao grupo LCG. CONCLUSÃO: Não foram encontradas diferenças estatisticamente significativas nos níveis de AVP entre os grupos, notando-se apenas uma maior variação de seus níveis séricos no grupo LCG (expressa sob a forma de picos séricos isolados). Hipernatremia e hiperosmolalidade estiveram presentes no grupo ME, indicando uma deficiência do sistema hipotálamo-hipofisário na produção e/ou liberação de AVP.

ABSTRACT

CONTEXTO: O carcinoma verrucoso de bexiga é uma neoplasia maligna muito rara, histologicamente semelhante ao condiloma acuminado. Normalmente apresenta-se associado à esquistossomose vesical (bilharzíase). Apenas 13 casos não relacionados à bilharzíase foram descritos até o momento, sendo que em nenhum deles foi relatada presença de coilocitose, um achado característico da infecção pelo papiloma vírus humano. RELATO DE CASO: Apresentamos um caso de carcinoma verrucoso de bexiga não relacionado à bilharzíase com presença de coilocitose e ausência de papiloma vírus humano. A literatura relacionada ao assunto é discutida.
