RESUMO
OBJECTIVES: The objective of this paper is to evaluate changes in lower urinary tract symptoms (LUTS), severity of pain and urodynamic parameters after minimally invasive nerve-sparing surgery for patients with endometriosis. METHODS: We analyzed 143 patients undergoing minimally invasive nerve-sparing surgery for endometriosis excision (laparoscopy/robot-assisted). The endometriosis was confirmed by preoperative clinical evaluation, magnetic resonance imaging (MRI) showing at least one lesion deeper than 5 mm, and histological confirmation after laparoscopy. We evaluated three points prior and after surgery: LUTS parameters according to the International Urogynecological Association; urodynamic measures of storage and voiding and the severity of the dyspareunia, dyschezia and dysmenorrhea assessed on a self-reported 11-point numeric rating scale. The Wilcoxon signed rank and McNemar tests were used for statistical analyses (p < 0.05). RESULTS: We observed significant improvements in LUTS after the surgery with postoperative symptom-free probabilities in urgency (64.5%), daytime frequency (38.5%), and dysuria (87.1%). However, slow stream prevalence increased significantly postsurgery (p = 0.022), with a 20.5% risk of asymptomatic patients developing this symptom. Urodynamic responses varied; for instance, maximum cystometric capacity improved significantly (p = 0.004), while postvoiding residual worsened (p = 0.006). Significant worsening in postvoiding residual occurred in women with normal preoperative values (p = 0.002), with a 17.7% risk of normal values becoming abnormal. Compliance or maximum cystometric capacity not considered normal preoperatively showed significant improvements (p < 0.001), but the risk of normal values becoming abnormal after surgery was 14.5%. CONCLUSION: The minimally invasive nerve-sparing surgery for endometriosis excision shows improvement in lower urinary tract symptoms, urodynamics parameters and severity of pain. The majority of patients became asymptomatic in the postoperative period. When compared to the benefits of the patients' surgical treatment, particularly when considering the reduction of pain, the risks of the lower urinary tract treatment seem to be acceptable. The surgical intervention seems to be a safe alternative in patients with endometriosis, although studies with larger samples are needed to confirm these findings.

Endometrial ablation (EA) is a minimally invasive surgical procedure to reduce abnormal uterine bleeding contemplated for women who have achieved their reproductive goals. EA consists of the destruction of the endometrial layer with preservation of the uterus, although EA has lower complication rates than hysterectomy, it may be associated with metrorrhagia recurrence. One of the major causes of treatment failure is incomplete ablation of the endometrium. Thanks to techniques that have been developed in recent years, endometrial ablation can be performed on an outpatient basis, including by radiofrequency ablation. The main objective of this case series was to report four cases in which Radiofrequency Endometrial Ablation (RFEA) was used to treat abnormal uterine bleeding at a single ambulatory surgical center in Brazil. Hysteroscopic evaluation of the uterine cavity was performed immediately prior to the RFEA to diagnose possible endometrial pathologies and again at the conclusion of the procedure to assess the aspect of the newly treated endometrium. Verification of the completeness of the ablation was assessed by a third hysteroscopy 30 or 60 days after the ablation. In this case series RFEA was efficacious and safe for outpatient use. Although radiofrequency endometrial ablation can be performed without the use of the hysteroscope, we believe it is an important tool for the timely verification of the completeness of the endometrial ablation.

A ablação endometrial (AE) é um procedimento cirúrgico minimamente invasivo destinado a mulheres com prole estabelecida visando redução do sangramento uterino anormal. A AE consiste na destruição da camada endometrial com a preservação do útero, apesar da AE possuir menores índices de complicação do que a histerectomia, pode estar associada a recorrência do sangramento. Uma das causas da falha de tratamento é a ablação incompleta do endométrio. Atualmente, a ablação endometrial pode ser realizada ambulatorialmente graças às técnicas que vêm sendo desenvolvidas nos últimos anos, as quais incluem o uso de radiofrequência. O objetivo dessa série de casos é descrever 4 casos de Ablação Endometrial por Radiofrequência (AERF) para o tratamento de sangramento uterino anormal realizados em um mesmo ambulatório especializado no Brasil. Uma avaliação histeroscópica da cavidade uterina foi realizada imediatamente antes da AERF para diagnosticar possíveis patologias endometriais e imediatamente ao final do procedimento, para avaliar o aspecto do endométrio recém tratado e a necessidade de nova aplicação de radiofrequência. A integralidade da ablação foi verificada por uma terceira histeroscopia após 30 ou 60 dias depois da ablaçao. A técnica mostrou-se adequada para uso ambulatorial. Embora a ablação endometrial por radiofrequência possa ser realizada sem o uso do histeroscópio, acreditamos que seja uma ferramenta importante para a verificação oportuna da integralidade da ablação endometrial.

RESUMO
ABSTRACT Purpose Bladder endometriosis (BE) accounts for 84% of cases of urinary tract involvement. The use of cystoscopy for preoperative evaluation is limited. The aim of this study was to evaluate the accuracy of preoperative dynamic cystoscopy (DC) in patients undergoing surgery for deep endometriosis and to describe the main findings and their impact on surgical planning. Materials and Methods This cross-sectional observational study was conducted from January 2011 to March 2022. DC findings were divided into two groups according to the depth of involvement. To estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), laparoscopic findings of bladder involvement and histopathological report were used as the gold standard. Results We included 157 patients in this study. 41 had abnormalities in DC. Of these, 39 had abnormalities that were confirmed intraoperatively. The sensitivity and specificity of the test were 58.21% and 97.78%, respectively. PPV was 95.12%, and NPV was 75.86%. The presence of any lesions in the DC had a diagnostic odds ratio (OR) of 61.28 for BE. Patients with BE type 2 had a higher rate of partial cystectomy than those with BE type 1 lesions (OR 9.72 CI 95% 1.9-49.1) Conclusion DC appears to be a highly specific test with lower sensitivity. DC abnormalities are associated with a higher ratio of bladder surgery for the treatment of deep endometriosis, and BE type 2 seems to be associated with a greater ratio (9.72) of partial cystectomy.
RESUMO
PURPOSE: To verify the predictors of intravasation rate during hysteroscopy. METHODS: Prospective observational study (Canadian Task Force classification II-1). All cases (n=200 women; 22 to 86 years old) were treated in an operating room setting. Considering respective bag overfill to calculate water balance, we tested two multiple linear regression models: one for total intravasation (mL) and the other for absorption rate (mL.min-1). The predictors tested (independent variables) were energy (mono/bipolar), tube patency (with/without tubal ligation), hysterometry (cm), age≤50 years, body surface area (m2), surgical complexity (with/without myomectomy) and duration (min). RESULTS: Mean intravasation was significantly higher when myomectomy was performed (442±616 versus 223±332 mL; p<0.01). In the proposed multiple linear regression models for total intravasation (adjusted R2=0.44; p<0.01), the only significant predictors were myomectomy and duration (p<0.01).In the proposed model for intravasation rate (R2=0.39; p<0.01), only myomectomy and hysterometry were significant predictors (p=0.02 and p<0.01, respectively). CONCLUSIONS: Not only myomectomy but also hysterometry were significant predictors of intravasation rate during operative hysteroscopy. .
OBJETIVO: Testar preditores do ritmo de intravasamento durante histeroscopia cirúrgica. MÉTODOS: Estudo prospectivo observacional (classificação: Canadian Task Force II-1) incluindo casos conduzidos em centro cirúrgico (n=200 mulheres; 22 a 86 anos de idade). Considerando os erros de aferição nas embalagens de solução de irrigação para calcular o balanço hídrico, nós testamos dois modelos de regressão linear múltipla: um para intravasamento total (mL) e outro para ritmo de intravasamento (mL.min-1). Os preditores testados (variáveis independentes) foram energia (mono/bipolar), permeabilidade tubária (com/sem ligadura tubária), histerometria (cm), status ovariano (idade≤50 anos), área de superfície corporal (m2), complexidade de cirurgia (com/sem miomectomia) e tempo de ressecção (min). RESULTADOS: O intravasamento médio foi significativamente maior quando miomectomia foi realizada (442±616 versus 223±332 mL, p<0,01). No modelo proposto para intravasamento total (R2 ajustado=0,44; p<0,01), os únicos preditores significativos foram miomectomia e tempo de duração (p<0,01). No modelo proposto para a taxa de intravasamento (R2=0,39; p<0,01), somente miomectomia e histerometria foram preditores significativos (p=0,02 e p<0,01, respectivamente). CONCLUSÕES: Não só a miomectomia mas também a histerometria são preditores significativo da taxa de intravasamento durante histeroscopia cirúrgica. .

O objetivo deste estudo foi estimar a prevalência de hipertensão em adultos residentes nas comunidades ribeirinhas do rio Madeira, previamente à operação da Usina Hidrelétrica Santo Antônio. Estudo transversal da prevalência de hipertensão arterial realizado com 841 adultos. Informações sobre condições sociodemográficas, morbidade referida, hábitos de vida, consumo de peixe e dados antropométricos foram avaliados. O método de regressão logística foi utilizado para estimar a odds ratio e seus respectivos intervalos de confiança. Entre os ribeirinhos, 26% (IC95%: 23%29%) dos adultos apresentaram hipertensão: 29% entre os homens (IC95%: 24%-33%) e 23% entre as mulheres (IC95%: 19%-27%). Nos homens, os fatores associados à hipertensão foram idade, IMC, glicemia e local de residência. Entre as mulheres, os fatores preditivos foram idade, triglicerídeos e glicemia. Os resultados deste estudo podem contribuir com a formulação de estratégias de monitoramento para prevenção de eventos cardiovasculares por parte dos órgãos de saúde estadual e municipal.
The aim of this cross-sectional study was to estimate the prevalence of hypertension among adults (n = 841) in communities along the Madeira River in the Brazilian Amazon, prior to startup of the Santo Antônio Hydroelectric Plant. The study gathered information on sociodemographic conditions, history of diseases, habits, fish consumption, and anthropometric parameters. Logistic regression was used to calculate odds ratios and the respective confidence intervals. Among the riverine communities, 26% (95%CI: 23%-29%) of adults presented hypertension (29% in men [95%CI: 24%-33%] and 23% in women [95%CI: 19%-27%]). Factors associated with hypertension were age, BMI, and place of residence in men and age, triglycerides, and blood glucose in women. The findings can contribute to strategies for state and municipal health services to monitor and prevent cardiovascular events.

Over the last 20 years several projects carried on the Madeira River basin in the Amazon produced a great amount data on total Hg concentration in different fish species. In this paper we discuss temporal trends in Hg contamination and its relation to body weight in some of those fishes, showing that even within similar groups, such as carnivorous and non-migratory fish, the interspecies variability in Hg accumulation is considerable.
Vários estudos têm sido desenvolvidos nos últimos 20 anos na bacia do Rio Madeira (Amazônia) com o objetivo de diagnosticar a presença de mercúrio em peixes e compreender o ciclo deste elemento no meio ambiente tropical. Neste artigo são discutidas tendências temporais na concentração de Hg e sua relação com a massa corporal de algumas espécies de peixes com diferentes hábitos alimentares, coletadas no Rio Madeira e no reservatório da hidroelétrica de Samuel, no Rio Jamari, Estado de Rondônia. Foi avaliada uma amostragem de peixes de 14 anos (1987 - 2000) com 86 espécies e um total de 1100 espécimes.
