Endoscopic Study of Ethmoidal Canals in Cadavers, Including a Histological Analysis of Their Contents.

Introduction The advent of the endoscope has enabled the use of the endonasal approach for a variety of diseases. Studying the ethmoidal canals is important for surgeries of the paranasal sinuses and the anterior base of the skull. Objective To investigate the ethmoidal canals and evaluate their structure, the presence of vessels and nerves, their location, and to perform an anatomopathological study of their contents. Methods We evaluated 20 cadavers (20 left and 20 right nasal cavities) through endoscopic dissection of the anterior base of the skull and exposure of the medial periorbita and dura mater; then, the ethmoidal canals were located and measured in relation to the anterior wall of the sphenoid sinus and between the ethmoidal canals, followed by removal of their content for histological analysis. Results Vessels were present in 75% of the left anterior ethmoidal canals, 70% of the left posterior ethmoidal canals, 75% of the left middle ethmoidal canals, 85% of the right anterior ethmoid canals, and 64.5% of the right posterior ethmoid canals; 50% of the right middle ethmoidal canals contained one vessel. Conclusion The ethmoidal canal does not necessarily contain an ethmoidal artery. Studies with a larger sample should be performed to quantify the correct proportion of arteries and ethmoidal canals.

Urinary Incontinence and Surgery for Obesity and Weight-Related Diseases: Are There Predictors of Improvement?

PURPOSE: The aim of this study was to evaluate changes in urinary incontinence (UI) before and after surgery for obesity in female patients and to identify factors related to the remission of symptoms. MATERIALS AND METHODS: This was a prospective cohort study with female patients over 18 years old who underwent surgery for obesity and weight-related diseases between June 2016 and September 2017. Urinary symptoms and quality of life related to UI were assessed based on a structured interview and the results of the validated questionnaires. RESULTS: Two hundred twenty-one patients were assessed pre-operatively, and 118 (53.3%) reported UI. Eighty-eight patients (74.6%) completed the pre- and postoperative questionnaires. After 6 to 12 months, patients were revaluated, and 50 (56.8%) were considered to be in remission of urinary symptoms. Women who had only a cesarean birth had a 117% increase in the probability of achieving remission of UI compared with women who had both vaginal and cesarean deliveries, and patients with an additional point in the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF) score at the beginning had a 4% lower probability of having remission of symptoms. CONCLUSIONS: Improvement in UI may be an important outcome of surgery for obesity and weight-related diseases. In this study, previous cesarean section was only associated with the highest rate of remission of symptoms, and patients with higher scores in the ICIQ-UI-SF had a lower probability of remission.

Urinary Incontinence and Quality of Life in Female Patients with Obesity.

OBJECTIVE: To analyze the prevalence of urinary incontinence (UI) in female patients with an indication for bariatric surgery, to investigate the potential risk factors and the impact on quality of life. METHODS: A cross-sectional study with female patients with obesity. The evaluation consisted of a structured interview, a specific study form and quality of life questionnaires. The Poisson regression was performed to identify independent risk factors related to UI. RESULTS: A total of 221 patients were enrolled; 118 of the study participants (53.4%) reported UI episodes. Mixed UI (MUI), stress UI (SUI) only, and urgency UI (UUI) only were reported by 52.5% (62), 33.9% (40) , and 13.5% (16) of these patients respectively. The prevalence of UI was increased by 47% among the women who had given birth vaginally and by 34% of the women who had entered menopause. Vaginal delivery and menopause were identified as independent risk factors related to UI. The mean International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) score was 9.36 ± 4.9. The severity of symptoms was considered moderate in 53.3% (63) of the patients with UI. CONCLUSION: Urinary incontinence impacts quality of life negatively, and the prevalence of UI is high among obese patients. In the present study, vaginal delivery and menopause were independently associated with UI.

OBJETIVO: Analisar a prevalência de incontinência urinária (IU), os fatores de risco e o impacto na qualidade de vida em pacientes femininas com indicação para realização de cirurgia bariátrica. MéTODOS: Estudo transversal com pacientes femininas obesas. A avaliação consistiu em entrevista estruturada, com questionários de estudo específico e de qualidade de vida. A regressão de Poisson foi utilizada para identificar os fatores de risco independentes para IU. RESULTADOS: Um total de 221 pacientes foram incluídos; 118 participantes (53.4%) relataram episódios de IU. Incontinência urinária mista, IU de esforço e IU de urgência foram relatadas por 52.5% (62), 33.9% (40) e 13.5%(16) das pacientes, respectivamente. A prevalência de IU foi 47% maior em mulheres que tiveram parto vaginal, e 34% maior em mulheres que já entraram no período da menopausa. Parto vaginal e menopausa foram identificados como fatores de risco independentes para IU. A média da pontuação do International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF) foi de 9.36 ± 4.9. A severidade dos sintomas foi considerada moderada em 53.3% (63) das pacientes com IU. CONCLUSãO: A IU impacta negativamente a qualidade de vida, e a prevalência de IU é maior em pacientes obesas. Neste estudo, parto vaginal e menopausa foram fatores de risco independentes para a ocorrência de IU.
