RESUMO Objetivo: Avaliar a prevalência e os fatores associados à percepção do medo de ser contaminado pelo novo coronavírus. Métodos: Estudo transversal realizado em Passo Fundo, Rio Grande do Sul, com indivíduos de ambos os sexos e 18 ou mais anos de idade. Coleta on-line de dados sociodemográficos, de saúde, de comportamento e de conhecimento acerca do vírus. Análise estatística descritiva e cálculo de prevalência e de razões de prevalência (RP) brutas e ajustadas. Resultados: Amostrados 920 participantes, com 64% de prevalência de medo de contaminação, sendo maior em indivíduos que trabalham (RP = 1,10; IC95 1,02-1,20), com idosos no domicílio (RP = 1,18; IC95 1,17-1,19), percepção negativa da saúde (RP = 1,15; IC95 1,02-1,31), avaliação de elevado risco de contaminação (RP = 1,30; IC95 1,23-1,38), com no mínimo um dos principais sinais/sintomas na semana anterior (RP = 1,12; IC95 1,11-1,13), que realizam maior número de medidas preventivas (RP = 1,27; IC95 1,15-1,40), vacinados contra a gripe (RP = 1,08; IC95 1,07-1,10) e que sabem que pertencem ao grupo de risco (RP = 1,17; IC95 1,14-1,19). Menor probabilidade do desfecho observada em idosos (RP = 0,74; IC95 0,60-0,91), profissionais ou estudantes da saúde (RP = 0,82; IC95 0,81-0,83) e em não fumantes (RP = 0,86; IC95 0,79-0,94). Conclusões: Observou-se elevada proporção de medo entre os participantes, especialmente entre aqueles que se percebem sob maior risco. Considerando o importante papel do medo na saúde mental das pessoas, os achados indicam a importância de intensificar ações educativas e informativas, visando ampliar o esclarecimento da população e reduzir os impactos da pandemia nesse aspecto.

ABSTRACT Objective: To assess the prevalence and factors associated with the perception of fear of being infected by the new coronavirus. Methods: Cross-sectional study carried out in Passo Fundo, Rio Grande do Sul, with individuals of both sexes and 18 years of age or older. Online data collection of sociodemographic, health and behavior characteristics as well as knowledge about the virus. Descriptive statistical analysis and calculation of prevalence and crude and adjusted prevalence ratios (PR). Results: Nine hundred and twenty participants were sampled, with a 64% prevalence of fear of contamination, being higher in working individuals (PR = 1.10; CI95 1.02-1.20), with elderly people at home (PR = 1.18; CI95 1.17-1.19), negative perception of health (PR = 1.15; CI95 1.02-1.31), assessment of high risk of contamination (PR = 1.30; CI95 1.23-1,38), with at least one of the main signs/symptoms in the previous week (PR = 1.12; CI95 1.11-1.13), who perform a greater number of preventive measures (PR = 1.27; CI95 1,15-1.40), vaccinated against influenza (PR = 1.08; CI95 1.07-1.10) and who know that they belong to the risk group (PR = 1.17; CI95 1.14-1,19). Lower probability of outcome observed in the elderly (PR = 0.74; CI95 0.60-0.91), health professionals or students (PR = 0.82; CI95 0.81-0.83) and in non-smokers (PR = 0.86; CI95 0.79-0.94). Conclusions: There was a high proportion of fear among the participants, especially among those who perceive themselves to be at greater risk. Considering the important role of fear in people's mental health, the findings indicate the importance of intensifying educational and informational actions, aiming to expand the clarification of the population and reduce the impacts of the pandemic in this regard.

RESUMO A incontinência urinária pós-prostatectomia tem importante impacto negativo na qualidade de vida do portador. O tratamento cirúrgico inclui slings masculinos e, entre os diversos modelos, os slings ajustáveis. O objetivo deste estudo foi avaliar a efetividade e a segurança do sling ajustável no tratamento da incontinência urinária pós-prostatectomia. Trata-se de revisão sistemática de literatura. Foram pesquisadas as seguintes bases de dados eletrônicas até janeiro de 2018: PubMed®, Embase, CENTRAL e LILACS. As palavras-chaves utilizadas nas estratégias de busca foram: “prostatectomy” [Mesh], “urinary incontinence” [Mesh] e “suburethral slings” [Mesh]. Foram incluídos ensaios clínicos randomizados e estudos observacionais controlados ou não com seguimento maior que 12 meses. Apenas um estudo randomizado com alto risco de viés foi localizado e concluiu a equivalência de efetividade de slings ajustáveis e não ajustáveis. Todos os outros estudos foram série de casos com pacientes de variados níveis de intensidade da incontinência e histórico de radioterapia pélvica e cirurgias prévias. A metanálise para 0 pad em 24 horas demonstrou efetividade de 53%. Para o desfecho 0 a 1 pad em 24 horas, a metanálise resultou em efetividade de 69%. Os fatores de risco para insucesso da cirurgia incluem radiação prévia, gravidade da incontinência urinária pós-prostatectomia e cirurgias anteriores. A metanálise da taxa de extrusão foi de 9,8%, e os efeitos adversos mais relatados foram dor e infecção local. Evidências de baixa qualidade indicam que os slings ajustáveis são efetivos para o tratamento da incontinência urinária pós-prostatectomia, com frequência de eventos adversos semelhantes à opção cirúrgica considerada padrão-ouro (o implante de esfíncter urinário artificial).

ABSTRACT Urinary incontinence after prostatectomy has a significant negative impact on the quality of life of the patient. The surgical treatment includes several models of male slings, such as adjustable slings. The objective of this study was to evaluate the effectiveness and safety of adjustable sling in the treatment of post-prostatectomy urinary incontinence. This is a systematic review of literature. The following electronic databases were searched until January 2018: PubMed®, Embase, CENTRAL and LILACS. The keywords used in the search strategies were: “prostatectomy” [Mesh], “urinary incontinence” [Mesh] and “suburethral slings” [Mesh]. Randomized clinical trials and observational studies, with or without Control Group, and follow-up of more than 12 months were included. Only one randomized study with high risk of bias was included and it concluded the effectiveness equivalence between adjustable and non-adjustable slings. All other studies were cases series with patients of varying levels of incontinence intensity and history of pelvic radiation therapy and previous surgeries. The meta-analysis for 0 pad in 24 hours demonstrated an effectiveness of 53%. For the 0 to 1 pad test in 24 hours, the meta-analysis resulted in an effectiveness of 69%. Risk factors for surgery failure include prior radiation, severity of post-prostatectomy urinary incontinence, and previous surgeries. The meta-analysis of the extrusion rate was 9.8% and the most commonly reported adverse effects were pain and local infection. Evidence of low quality indicates that adjustable slings are effective for treating post-prostatectomy urinary incontinence, with frequency of adverse events similar to the surgical option considered gold standard (the artificial urinary sphincter implant).

Abstract Enterococcus faecalis are gram positive bacteria that can mostly resist endodontic therapy, inducing persistent infection in the root canal system. Endodontic sealers with antimicrobial activity may help eliminate residual microorganisms that survive endodontic treatment. The present study aimed at comparing the antimicrobial activity of Acroseal, Sealapex and AH Plus endodontic sealers in an in vitro biofilm model. Bovine dentin specimens (144) were prepared, and twelve blocks for each sealer and each experimental time point (2, 7 and 14 days) were placed and left in contact with plates containing inoculum of E. faecalis (ATCC 51299), to induce biofilm formation. After 14 days, the samples were transferred to another plate with test sealers and kept at 37°C and 5% CO2 for 2, 7 and 14 days. The specimens without sealers were used as a control for each period. The samples were agitated in a sonicator after each experiment. The suspensions were agitated in a vortex mixer, serially diluted in saline, and triple plated onto m-Enterococcus agar. Colonyforming units were counted, and the data were statistically analyzed using ANOVA, Shapiro-Wilk and Kruskal-Wallis one-way tests (p < 0.05) to determine antimicrobial potential. Sealapex showed significant differences at all the experimental time points, in comparison with all the other groups. AH Plus and Acroseal showed antimicrobial activity only on the 14th experimental day. Neither of the sealers tested were able to completely eliminate the biofilm. Sealapex showed the highest antimicrobial activity in all the experimental periods. The antimicrobial activity of all the sealers analyzed increased over time.

PURPOSE: The reported incidence of urinary incontinence (UI) due to bladder dysfunction following surgery of BPH is variable. We described the causes of incontinence in a large group of men that developed this unsual complication and analyzed the influence of age on the prevalence of bladder dysfunction. MATERIALS AND METHODS: We wvaluated a total of 125 patients with urinary incontinence following surgical treatment for BPH : Transurethral resection of the prostate (81men) and open prostatectomy (44 men). A third group of 21 patients with incontinence following radical prostatectomy was used for comparison. All patients underwent urodynamic analysis. Urethral Sphincter Insufficiency (USI)was defined as involuntary loss of urine induced by Valsalva maneuver in the absence of a detrusor contraction. Bladder dysfunction was defined as detrusor overactivity and/or decreased compliance. RESULTS: Urethral sphincter insufficiency was the most common etiology of urinary incontinence in the three groups of patients. However, bladder dysfunction was observed in 59.3%, 56.8% and 57.1% of patients who underwent transurethral resection, open prostatectomy and radical prostatectomy, respectively. Median patient age was 69 and 75 years for patients with and without bladder dysfunction, respectively. A logistic regression model for the presence of bladder dysfunction showed that age was a statistically significant predictor. CONCLUSIONS: Urethral Sphincter insufficiency is the main cause of incontinence following surgery for BPH. Bladder dysfunction may be the isolated cause of incontinence in approximately 25% of patients. The chances of bladder dysfunction rises 5.3% for each year added to patient age. Patients older than 70 years have twice the probablility of post procedural incontinence.

OBJECTIVES: In this preliminary study we report the development of the video urodynamic technique using magnetic resonance imaging (MRI). MATERIALS AND METHODS: We studied 6 women with genuine stress urinary incontinence, diagnosed by history and physical examination. Urodynamic examination was performed on multichannel equipment with the patient in the supine position. Coughing and Valsalva maneuvers were performed at volumes of 150, 250 and 350 mL. Simultaneously, MRI was carried out by using 1.5 T GE Signa CV/i high-speed scanner with real time fluoroscopic imaging possibilities. Fluoroscopic imaging was accomplished in the corresponding planes with T2-weighted single shot fast spin echo sequences at a speed of about 1 frame per second. Both studies were recorded and synchronized, resulting in a single video urodynamic examination. RESULTS: Dynamic MRI with cine-loop reconstruction of 1 image per second demonstrated the movement of all compartment of the relaxed pelvis during straining with the concomitant registration of abdominal and intravesical pressures. In 5 patients, urinary leakage was demonstrated during straining and the Valsalva leak point pressure (VLPP) was determined as the vesical pressure at leak subtracted from baseline bladder pressure. Mean VLPP was 72.6 cm H2O (ranging from 43 to 122 cm H2O). CONCLUSIONS: The concept of MRI video urodynamics is feasible. In a clinical perspective, practical aspects represent a barrier to daily use and it should be recommended for research purposes.

Every year there are 10 thousand new cases of patients victimized by spinal cord trauma (SCT) in the United States and it is estimated that there are 7 thousand new cases in Brazil. Eighty percent of patients are fertile males. Infertility in this patient group is due to 3 main factors resulting from spinal cord lesions: erectile dysfunction, ejaculatory disorder and low sperm counts. Erectile dysfunction has been successfully treated with oral and injectable medications, use of vacuum devices and penile prosthesis implants. The technological improvement in penile vibratory stimulation devices (PVS) and rectal probe electro-ejaculation (RPE) has made such procedures safer and accessible to patients with ejaculatory dysfunction. Despite the normal number of spermatozoa found in semen of spinal cord-injured patients, their motility is abnormal. This change does not seem to be related to changes in scrotal thermal regulation, frequency of ejaculation or duration of spinal cord damage but to factors related to the seminal plasma. Despite the poor seminal quality, increasingly more men with SCT have become fathers through techniques ranging from simple homologous insemination to sophisticated assisted reproduction techniques such as intracytoplasmic sperm injection (ICSI).
