ABSTRACT
Abstract: Introduction. Minimal hepatic encephalopathy (MHE) can reverse after short-term treatment. However, relapse rate of MHE after stopping treatment has not been studied so far. We aimed to evaluate long-term (9 months) efficacy of a short-term (3 months) treatment of MHE with lactulose/rifaximin, for maintenance of remission from MHE. Material and methods. In this prospective study, consecutive patients with cirrhosis and MHE were treated with lactulose/rifaximin for 3 months. After treatment, they were followed up for 6 months. Psychometric testing for diagnosis of MHE was performed at baseline, 3 months and 9 months. Results. Of the 527 patients screened, 351 were found eligible and tested for MHE. Out of these, 112 (31.9%) patients had MHE (mean age 55.3 years; 75% males). They were randomized to receive Rifaximin (n = 57; 1,200 mg/day) or Lactulose (n = 55; 30-120 mL/day) for three months. At 3 months, 73.7% (42/57) patients in Rifaximin group experienced MHE reversal compared to 69.1% (38/55) in Lactulose group (p = 0.677). Six months after stopping treatment, 47.6% (20/42) in rifaximin group and 42.1% (16/38) patients in lactulose group experienced MHE relapse (p = 0.274). The overt hepatic encephalopathy development rate (7.1% vs. 7.9%) and mortality rate (0.23% vs. 0%) were similar in both groups. The Child-Turcotte-Pugh score and model for end stage liver disease (MELD) scores of patients who had MHE relapse were higher compared to those who didn’t. On multivariate regression analysis, MELD score was an independent predictor of MHE relapse. Conclusion. Of the patients who became MHE negative after short-term (3 months) treatment with rifaximin/lactulose, almost 50% had a relapse of MHE at 6 months follow-up.

RESUMO Objetivos Estimar incidência, determinar fatores de risco e propor modelo de predição de risco para desenvolvimento de dermatite associada a incontinência em pacientes adultos críticos. Método Trata-se de um estudo de coorte concorrente realizado com 157 pacientes críticos. A coleta de dados foi conduzida diariamente entre fevereiro e julho de 2015 em hospital público e de ensino de Belo Horizonte, MG. Os dados foram lançados em banco de dados, submetidos a análise descritiva de sobrevida e multivariada. Resultados Obteve-se uma incidência global de 20,4%. Foram encontrados 19 fatores de risco que apresentaram associação significativa com o problema. As variáveis encontradas no modelo de predição de risco foram: sexo masculino, trauma, uso de hipnótico/sedativos, lactulona, suporte nutricional, fezes pastosas e queixa de ardência (local). Conclusão Os resultados mostraram que a dermatite é um achado clínico comum em pacientes adultos críticos e merece atenção especial para maior qualidade da assistência de enfermagem.
RESUMEN Objetivos Estimar incidencia, determinar factores de riesgo y proponer modelo de predicción de riesgo para el desarrollo de la dermatitis asociada a la incontinencia en pacientes adultos críticos. Método Se trata de un estudio de cohorte concurrente de 157 pacientes críticamente enfermos. La recolección de datos se realizó diariamente entre febrero y julio de 2015, en un hospital público y de enseñanza de Belo Horizonte-MG. Los datos se introdujeron en la base de datos, sometidos a análisis descriptivo, de supervivencia y multivariada. Resultados Se obtuvo una incidencia global del 20,4%. Se encontraron 19 factores de riesgo asociados significativamente con el problema. Las variables identificadas en el modelo de predicción de riesgo fueron: sexo masculino, trauma, uso de hipnóticos/sedantes, lactulona, soporte nutricional, heces sueltas y queja de ardor (local). Conclusión Los resultados mostraron que la dermatitis es un hallazgo clínico frecuente en pacientes adultos críticos y merece una atención especial para una mayor calidad de los cuidados de enfermería.
ABSTRACT Objectives Estimate incidence, determine risk factors and propose a prediction model for the development of incontinence- associated dermatitis critically ill adult patients. Method Concurrent cohort study with 157 critically ill patients. Data collection was daily performed between February and July 2015, at a public teaching hospital of Belo Horizonte, Minas Gerais. Data was entered in a database and subjected to descriptive, survival and multivariate analysis. Results An overall incidence of 20.4% was obtained. Nineteen (19) risk factors significantly associated with the disorder were found. The variables identified in the risk prediction model were male, trauma, use of hypnotics/sedatives, lactulose, nutritional support, loose stools and complaints of burning. Conclusion The results showed that dermatitis is a common clinical finding in critically ill adult patients and requires special attention from the nursing staff.

Background: Colonoscopy is the most frequent exam used to evaluate colonic mucosa, allowing the diagnosis and treatment of many diseases. The appropriate bowel preparation is indispensable for the realization of colonoscopy. Therefore, it is necessary the use of laxative medications, preferentially by oral administration. Aim: To compare two medications used in bowel preparation in adult patients going to ambulatory colonoscopy and to analyze the patients' profile. Methods: A double-blind prospective study with 200 patients, randomized in two groups: one that received polyethilene glycol and another that received lactulose. The patients answered to questionnaires to data compilation, as tolerance, symptoms and complications related to preparation. Besides, it was also evaluated the prepare efficacy related to the presence of fecal residue. Results: Intestinal habit alterations and abdominal pain were the main reasons to realize the exams and hypertension was the most prevalent comorbidity. Ten percent of the ones who received lactulose didn't get to finish the preparation and 50% considered the taste "bad, but tolerable". The most common subjective symptom after the medication was nausea, especially after lactulose. During the exam, most of the patients who used lactulose had a "light discomfort" and the ones who used polyethilene glycol considered the discomfort as "tolerable". The quality of the preparation was good in 75%, undependable of the medication that was used. Conclusion : Polyethilene glycol was more tolerable when compared to lactulose, without difference on the quality of the preparation. .
Racional - A colonoscopia é o exame mais utilizado atualmente para avaliação da mucosa colônica, permitindo diagnóstico e tratamento de diversas doenças. O preparo de cólon adequado é imprescindível para a realização do exame. Para tanto, é necessária a utilização de laxantes, cuja via preferencial de preparo é a oral. Objetivo - Comparar duas soluções para preparo de cólon nos pacientes adultos a serem submetidos à colonoscopia em regime ambulatorial e o perfil destes pacientes. Métodos - Estudo prospectivo duplo-cego com 200 pacientes distribuídos aleatoriamente em dois grupos: um que recebeu dose padrão de polietilenoglicol e o outro que recebeu dose padrão de lactulose. Os pacientes responderam a questionários para compilação de dados, como tolerância, sintomas e complicações relacionadas ao preparo. Além disso, foi avaliada também a eficácia do preparo com relação à presença de resíduos fecais. Resultados - Alteração do hábito intestinal e dor abdominal foram os principais motivos para o exame, sendo que hipertensão a comorbidade mais prevalente. Dez por cento dos que receberam lactulona não conseguiram completar o preparo e 50% consideraram o gosto do preparo "ruim, mas tolerável". O sintoma subjetivo mais comum após o preparo foi náusea, principalmente após a lactulona. Durante o exame, a maioria dos usuários da lactulona teve desconforto "leve", sendo que os que usaram polietilenoglicol consideraram o desconforto como "tolerável". A qualidade do preparo foi boa em 75%, independentemente do preparo utilizado. Conclusão - O polietilenoglicol apresentou melhor tolerância quando comparado à lactulona, não havendo diferença na qualidade do preparo. .

El eritema anular centrífugo (EAC) es una enfermedad que pertenece al grupo de los "eritemas figurados" y ha sido asociada con múltiples condiciones. Presentamos un caso de EAC, que se desarrolló mientras recibía tratamiento con lactulosa. Se realizó una búsqueda de otros posibles agentes causales que resultó negativa. Remarcamos la confirmación de esta patología con la biopsia cutánea y la importancia de la búsqueda de un posible factor desencadenante
