Pelvic-Floor Rehabilitation, Part 1 : Comparison of Two Surface Electrode Placements During Stimulation of the Pelvic-Floor Musculature in Women Who Are Continent Using Bipolar Interferential Currents

Background and Purpose. Electrical stimulation of the pelvic floor is used as an adjunct in the conservative treatment of urinary incontinence. No consensus exists, however, regarding electrode placements for optimal stimulation of the pelvic-floor musculature. The purpose of this study was to compare two different bipolar electrode placements, one suggested by Laycock and Green (L2) the other by Dumoulin (D2), during electrical stimulation with interferential currents of the pelvic-floor musculature in continent women, using a two-group crossover design. Subjects. Ten continent female volunteers, ranging in age from 20 to 39 years (X̅=27.3, SD=5.6), were randomly assigned to one of two study groups. Methods. Each study group received neuromuscular electrical stimulation (NMES) of the pelvic-floor musculature using both electrode placements, the order of application being reversed for each group. Force of contraction was measured as pressure (in centimeters of water [cm H2O]) exerted on a vaginal pressure probe attached to a manometer. Data were analyzed using a two-way, mixed-model analysis of variance. Results. No difference in pressure was observed between the two electrode placements. Differences in current amplitude were observed, with the D2 electrode placement requiring less current amplitude to produce a maximum recorded pressure on the manometer. Subjective assessment by the subjects revealed a preference for the D2 electrode placement (7 of 10 subjects). Conclusion and Discussion. The lower current amplitudes required with the D2 placement to obtain recordings comparable to those obtained with the L2 technique suggest a more comfortable stimulation of the pelvic-floor muscles. The lower current amplitudes required also suggest that greater increases in pressure might be obtained with the D2 placement by increasing the current amplitude while remaining within the comfort threshold. These results will help to define treatment guidelines for a planned clinical study investigating the effects of NMES and exercise in the treatment of urinary stress incontinence in women postpartum.

Pelvic floor muscles training to reduce symptoms and signs of vulvovaginal atrophy : a case study

Objective: Vulvovaginal atrophy (VVA), caused by decreased levels of estrogen, is a common problem in aging women. Main symptoms of VVA are vaginal dryness and dyspareunia. First-line treatment consists of the application of local estrogen therapy (ET) or vaginal moisturizer. In some cases however, symptoms and signs persist despite those interventions. This case study describes a 77-year-old woman with severe VVA symptoms despite use of local ET and the addition of pelvic floor muscle (PFM) training to her treatment. Methods: A patient with stress urinary incontinence and VVA was referred to a randomized clinical trial on PFM training. On pretreatment evaluation while on local ET, she showed VVA symptoms on the ICIQ Vaginal Symptoms questionnaire and the ICIQ-Female Sexual Matters associated with lower urinary tract Symptoms questionnaire, and also showed VVA signs during the physical and dynamometric evaluation of the PFM. She was treated with a 12-week PFM training program. Results: The patient reported a reduction in vaginal dryness and dyspareunia symptoms, as well as a better quality of sexual life after 12 weeks of PFM training. On posttreatment physical evaluation, the PFMs' tone and elasticity were improved, although some other VVA signs remained unchanged. Conclusions: Pelvic floor muscle training may improve some VVA symptoms and signs in women taking local ET. Further study is needed to investigate and confirm the present case findings and to explore mechanisms of action of this intervention for VVA.

As implicações da histerectomia nas mulheres em idade reprodutivas: Perceção dos enfermeiros bloco operatório, do Hospital Dr. Baptista de Sousa

A histerectomia consiste na remoção do útero por meio de cirurgia que pode ser efetuada pela via abdominal ou vaginal, podendo ser ainda classifica em total ou subtotal. De acordo com os dados estatísticos analisados nota-se um aumento considerável de mulheres a serem submetidas a histerectomia em Cabo Verde. No caso São Vicente, os dados estatísticos apontam que de 2013 a 2016 foram realizadas duzentos e quarentas e seis (246) histerectomias em mulheres com idade compreendida entre os 28 aos 86 anos, sendo que 41% destas mulheres encontra-se na idade reprodutiva. Esta foi de uma pesquisa de abordagem qualitativa de natureza descritiva, desenvolvida no Hospital Dr. Baptista de Sousa, no serviço do bloco operatório no período de março a julho de 2016, em que foram entrevistadas nove (9) enfermeiros, deste serviço, com o objetivo de conhecer as suas perceções sobre as implicações da histerectomia nas mulheres em idade reprodutiva. Sendo a entrevista estruturada o método de apoio para a recolha de informações pertinentes a esta realização. As descobertas da pesquisa deram origem a três (3) categorias: (1) perceção dos enfermeiros sobre histerectomia; (2) perceção dos enfermeiros sobre as implicações de histerectomia e (3) assistência de enfermagem as mulheres submetidas a histerectomia.

Elevación transitoria de TSH neonatal asociada a factores de riesgo de parto pretérmino

Introducción: La hipotiroxinemia es una alteración transitoria frecuente en el prematuro que resuelve sin medicación, es importante conocer los factores que se asocian con esta alteración para disminuir el tratamiento inoportuno y el aumento de costos en atención en salud que puede implicar un diagnóstico errado de hipotiroidismo congénito. Por medio de este estudio se evaluó la asociación entre elevación transitoria de la TSH neonatal y algunas variables asociadas a parto pretérmino en pacientes atendidos en la Clínica Materno Infantil Colsubsidio nacidos entre Enero 2014 a Abril de 2015. Metodología: Se realizó un estudio de casos y controles, analítico, retrospectivo. Los casos fueron prematuros con elevación de TSH sin hipotiroidismo congénito, los controles fueron prematuros con TSH normal, seleccionados de manera aleatoria 70 casos, 140 controles con una relación 1:2. Se realizaron asociaciones mediante prueba de chi cuadrado y análisis multivariado para controlar factores de confusión. Resultados: La edad gestacional promedio para casos fue 34.6±1.8, para controles 34.2±2.4. Ambas poblaciones fueron comparables. Los factores con resultados estadísticamente significativos fueron: Pielonefritis (p 0.04), hipertensión inducida por el embarazo (p 0.00), presencia de anemia (p 0.02) y embarazo múltiple (p0.03). Los resultados de regresión logística establecieron que la pielonefritis, hipertensión y anemia son factores de riesgo con resultados estadísticamente significativos. Discusión: Los resultados permitieron documentar que existen factores de riesgo para prematurez, como la pielonefritis, anemia materna e hipertensión inducida por el embarazo, que influyen en los valores de TSH de cordón umbilical que no necesariamente conllevan al desarrollo de hipotiroidismo congénito
