RESUMO
OBJETIVO: Valorar la utilidad de la biopsia transpedicular percutánea guiada por Tomografía Axial Computarizada en conjunto con la sistematización de estudios como pruebas diagnósticas de la etiología de la destrucción vertebral. MÉTODOS: Estudio de serie de casos prospectivo transversal de 21 pacientes a los que se les realizó biopsia transpedicular percutánea guiada por Tomografía Axial Computarizada y estudios de laboratorio y gabinete de marzo a julio del 2011, para evaluar su utilidad en el diagnóstico de destrucción vertebral. RESULTADOS: Fueron 21 pacientes, 14 hombres y 7 mujeres, con edad media de 59,2 años, cuyos niveles más afectados estuvieron en L1, L2 y L3. El reporte de la biopsia tuvo una precisión diagnóstica del 90,4%. En 2 casos se realizó correlación clínica entre biopsia y sistematización de estudios para obtener el diagnóstico. CONCLUSIÓN: La biopsia guiada por Tomografía Axial Computarizada es una técnica sencilla, útil, de bajo costo y eficaz en el estudio de la destrucción vertebral; la sistematización de estudios permite corroborar el diagnóstico de la biopsia.
OBJETIVO: Avaliar a utilidade da biópsia transpedicular percutânea guiada por tomografia axial computadorizada em conjunto com a sistematização de estudos, como exames diagnósticos da etiologia da destruição vertebral. MÉTODOS: Estudo de série de casos, prospectivo e transversal de 21 pacientes submetidos à biópsia transpedicular percutânea guiada por tomografia axial computadorizada e exames laboratoriais e radiológicos, de março a julho de 2011, para avaliar sua utilidade no diagnóstico de destruição vertebral. RESULTADOS: Foram analisados 21 pacientes, 14 homens e 7 mulheres, com média de idade de 59,2 anos, cujos níveis mais afetados foram L1, L2 e L3. O laudo da biópsia teve precisão diagnóstica de 90,4%. Em dois casos, realizou-se a correlação clínica entre biópsia e sistematização de exames para obter o diagnóstico. CONCLUSÃO: A biópsia guiada por tomografia axial computadorizada é uma técnica simples, útil, de baixo custo e eficaz para o estudo da destruição vertebral; a sistematização de estudos permite corroborar o diagnóstico da biópsia.
OBJECTIVE: To evaluate the usefulness of percutaneous transpedicular biopsy guided by CT together with systematic studies such as diagnostic tests of the etiology of vertebral destruction. METHODS: Case series, prospective and crossover study of 21 patients who underwent percutaneous transpedicular biopsy guided by CT and laboratory tests and radiological studies from March to July 2011, to evaluate its usefulness in the diagnosis of vertebral destruction. RESULTS: We analyzed 21 patients, 14 men and 7 women, mean age 59.2 years, whose most affected levels were L1, L2, and L3. The biopsy report had diagnostic accuracy of 90.4%. In 2 patients the clinical correlation between biopsy and systematization of diagnostic studies was carried out. CONCLUSION: CT-guided biopsy is a simple, useful, inexpensive, and effective technique for the study of vertebral destruction; the systematic studies allow us to corroborate the diagnosis made by biopsy.

BACKGROUND: Thoracic scoliosis is a lateral curvature of the spine associated with restrictive lung defects, manifested by a decrease in respiratory function tests. We undertook this study to evaluate the effect of a respiratory rehabilitation program over lung function in children with scoliosis. METHODS: We carried out a prospective and deliberate intervention study including 25 consecutive patients, aged 6 to 18 years, diagnosed with thoracic scoliosis. The respiratory rehabilitation program was structured into two phases: institutional and private residence. Statistical analysis was carried out using descriptive parameters and paired t-test and Wilcoxon signed-ranks test. Spearman correlation was used to measure intensity of association among variables. Statistical significance was considered when p <0.05. RESULTS: Idiopathic scoliosis was present in 52% of patients, with right dorsal curvature in 72%. Cobb angle average was 50.6° ± 29.7°. Most importantly, we found a negative correlation between this angle on left curvature and lung function. Initially, the main respiratory symptoms were dyspnea with poor effort tolerance in 52%. After treatment, 88% of patients were asymptomatic and only 4% presented poor effort tolerance. Oxygen saturation and forced vital capacity percentage had a significant increment after the program. CONCLUSION: Respiratory rehabilitation has a positive effect on increasing pulmonary function of children with scoliosis.
