Reproducibility of the six-minute walk test and Glittre ADL-test in patients hospitalized for acute and exacerbated chronic lung disease

Background: The 6-minute walk test (6MWT) and the Glittre ADL-test (GT) are used to assess functional capacity and exercise tolerance; however, the reproducibility of these tests needs further study in patients with acute lung diseases. Objectives: The aim of this study was to investigate the reproducibility of the 6MWT and GT performed in patients hospitalized for acute and exacerbated chronic lung diseases. Method: 48 h after hospitalization, 81 patients (50 males, age: 52±18 years, FEV1: 58±20% of the predicted value) performed two 6MWTs and two GTs in random order on different days. Results: There was no difference between the first and second 6MWT (median 349 m [284-419] and 363 m [288-432], respectively) (ICC: 0.97; P<0.0001). A difference between the first and second tests was found in GT (median 286 s [220-378] and 244 s [197-323] respectively; P<0.001) (ICC: 0.91; P<0.0001). Conclusion: Although both the 6MWT and GT were reproducible, the best results occurred in the second test, demonstrating a learning effect. These results indicate that at least two tests are necessary to obtain reliable assessments. .

Resultados de la artroplastia de interposición tendinosa en la seudoartrosis del escafoides carpiano / Results of tendinous interposition arthroplasty in carpal scaphoid pseudoarthrosis

A pesar de existir un gran número de procedimientos para el tratamiento de la seudoartrosis del escafoides carpiano, ninguno reporta resultados totalmente satisfactorios; lo que constituye un reto para el cirujano. Objetivo: evaluar los resultados de la artroplastia de interposición tendinosa en la seudoartrosis del escafoides carpiano. Método: se realizó un estudio descriptivo prospectivo a un grupo de pacientes con seudoartrosis del escafoides carpiano, atendidos en el Hospital Militar Universitario Octavio de la Concepción y de la Pedraja de Camagüey, desde noviembre de 2003 hasta octubre de 2010. El universo lo conformaron 34 enfermos y la muestra no probabilística quedó constituida por 28 pacientes. Las variables de estudio fueron la edad, sexo, tiempo de rehabilitación postoperatoria y las complicaciones.Resultados: predominó el grupo de edad entre 35 y 44 años para un 42,8 Por ciento; el sexo más afectado fue el masculino con un 78,5 por ciento; el tiempo de rehabilitación postoperatoria necesario ocurrió en general entre cuatro y 12 semanas para un 64,2 por ciento; y los resultados de la artroplastia fueron excelentes y buenos en el 78,7 por ciento del total de pacientes operados

Although there are many surgical procedures to treat carpal scaphoid pseudoarthrosis, none reports satisfactory results; what is a challenge for the surgeon. Objective: to evaluate the results of tendinous interposition arthroplasty in carpal scaphoid pseudoarthrosis. Method: a prospective and descriptive study in patients with the said affection was conducted, treated at Dr. Octavio de la Concepción y de la Pedraja University Military Hospital in Camagüey from November 2003 to October 2010. The universe was constituted by 34 patients, non probabilistic sampling composed of 28 patients. The study variables were: age, sex, postoperative rehabilitation time and more frequent omplications. Results: the age group from 35 to 44 years with a 42,8 percent prevailed; male sex was the most affected to a 78,5 percent; postoperative rehabilitation time occurred from 4 to 12 weeks for a 64,2 percent; and results of arthroplasty were excellent and good in a 78,7 percent of the total of patients operated
