ABSTRACT
Background. Paracoccidioidomycosis (PCM) is a systemic mycosis of acute and chronic evolution, caused by species belonging to the genus Paracoccidioides. It is considered the most prevalent systemic endemic mycosis in Latin America, with cases in the tropical and subtropical regions. Residual PCM refers to the fibrotic scar sequelae resulting from the disease treatment which, when associated with collagen accumulation, leads to functional and anatomic alterations in the organs. Aims. The aim of this study was to evaluate the vocal function of patients with residual PCM in upper airways and digestive tract. Methods. We performed a cross-sectional study in 2010 in a cohort of 21 patients with residual PCM in upper airways and digestive tract. Results. The average age was 49.48±9.1 years, and only two (9.5%) patients were female. The study was performed in the 1-113 month-period (median 27) after the end of drug treatment. Five (23.8%) patients had alterations in the larynx as a sequela of the disease. However, all patients had vocal changes in vocal auditory perceptual analysis by GRBASI scale. The computerized acoustic analysis using the software Vox Metria, showed that 11 patients (52.4%) presented alterations in jitter, 15 (71.4%) in shimmer, 8 (38.1%) in F0, 4 (19%) in glottal to noise excitation (GNE), 7 (33.3%) in the presence of noise and 12 (57.1%) in the presence of vibratory irregularity. Conclusions. The great frequency of alterations in residual PCM suggests that the patients in such phase could benefit from a multidisciplinary treatment, offering them integral monitoring of the disease, including speech rehabilitation after the PCM is healed (AU)
Antecedentes. La paracoccidioidomicosis (PCM) es una micosis sistémica de evolución aguda y crónica causada por especies que pertenecen al género Paracoccidioides. Se considera que es la micosis sistémica endémica de mayor prevalencia en América Latina, con casos en las regiones tropicales y subtropicales. La PCM residual se refiere a las secuelas de las cicatrices fibróticas que provoca el tratamiento de la enfermedad; cuando se asocia con la acumulación de colágeno, conduce a alteraciones funcionales y anatómicas en los órganos. Objetivos. El objetivo de este estudio fue evaluar la función vocal de los pacientes con PCM residual en las vías respiratorias superiores y el tubo digestivo. Métodos. En 2010 se realizó un estudio transversal con una cohorte de 21 pacientes con PCM residual en las vías respiratorias superiores y el tubo digestivo. Resultados. La media de edad fue 49,48±9,1 años y solo dos pacientes (9,5%) eran mujeres. El estudio se realizó durante un período entre 1 y 113 meses (mediana: 27) después de finalizado el tratamiento farmacológico. Cinco pacientes (23,8%) presentaban alteraciones en la laringe como secuela de la enfermedad. Sin embargo, se encontró que todos los pacientes tenían alteraciones vocales en el análisis de percepción auditiva vocal por la escala GRBASI. El análisis acústico computarizado con el software Vox Metria mostró que 11 pacientes (52,4%) presentaron alteraciones en la variación ciclo a ciclo de la frecuencia fundamental (parámetro denominado jitter), 15 (71,4%) en la variación ciclo a ciclo de la amplitud de la señal vocal (shimmer), 8 (38,1%) en la frecuencia fundamental (F0), 4 (19%) en la relación señal-ruido (glottal to noise excitation - GNE), 7 (33,3%) en la existencia de ruido y 12 (57,1%) en la existencia de irregularidad vibratoria. Conclusiones. La gran frecuencia de alteraciones en la PCM residual indica que los pacientes en dicha fase podrían beneficiarse de un tratamiento multidisciplinario con vigilancia integral de la enfermedad que incluyera la rehabilitación del habla tras la curación de la PCM (AU)

CONCLUSIONS: The great frequency of alterations in residual PCM suggests that the patients in such phase could benefit from a multidisciplinary treatment, offering them integral monitoring of the disease, including speech rehabilitation after the PCM is healed.
