Late bilateral vocal cord palsy following endotracheal intubation due to COVID-19 pneumonia.

Vocal cord paralysis is a rare but severe complication after orotracheal intubation. The most common cause is traumatic, due to compression of the recurrent laryngeal nerve between the orotracheal tube cuff and the thyroid cartilage. Other possible causes are direct damage to the vocal cords during intubation, dislocation of the arytenoid cartilages, or infections, especially viral infections. It is usually due to a recurrent laryngeal nerve neuropraxia, and the course is benign in most patients. We present the case of a man who developed late bilateral vocal cord paralysis after pneumonia complicated with respiratory distress due to SARS-CoV-2 that required orotracheal intubation for 11 days. He presented symptoms of dyspnea 20 days after discharge from hospital with subsequent development of stridor, requiring a tracheostomy. Due to the temporal evolution, a possible contribution of the SARS-CoV-2 infection to the picture is pointed out.

Parálisis bilateral tardía de cuerdas vocales trasintubación endotraqueal por neumonía COVID-19 / Late bilateral vocal cord palsy following endotracheal intubation due to COVID-19 pneumonia

La parálisis de cuerdas vocales es una complicación poco frecuente, aunque severa, tras una intubación orotraqueal. La causa más frecuente es la traumática, debido a la compresión del nervio laríngeo recurrente entre el maguito del tubo orotraqueal y el cartílago tiroides. Otras posibles causas son lesión directa de las cuerdas vocales durante la intubación, luxación de los cartílagos aritenoides e infecciones, sobre todo víricas. Suele deberse a una neuroapraxia del nervio laríngeo recurrente, y el curso es benigno en la mayoría de los pacientes. Presentamos el caso de un varón que desarrolló una parálisis de cuerdas vocales bilateral tras una neumonía complicada con distrés respiratorio por SARS-CoV-2 que requirió intubación orotraqueal durante 11 días. Presentó clínica de disnea a los 20 días del alta hospitalaria con desarrollo posterior de estridor, siendo necesaria la realización de una traqueostomía. Debido a la evoución temporal, se apunta una posible contribución de la infección por SARS-CoV-2 al cuadro.(AU)

Estudio del daño renal en el paciente pediátrico con vejiga neurógena y su relación con el patrón de funcionamiento vesical y el tratamiento recibido / Study of kidney damage in paediatric patients with neurogenic bladder and its relationship with the pattern of bladder function and treatment received

Objetivos: El fallo renal es la principal causa de morbimortalidad en pacientes con mielodisplasia. Analizamos la presencia de lesiones renales en la gammagrafía (DMSA) de estos pacientes y la relacionamos con el tipo de funcionamiento vesical, así como con el retraso en recibir un manejo adecuado. Material y métodos: Realizamos un estudio retrospectivo de pacientes con mielodisplasia en nuestro hospital desde 2004. Analizamos datos epidemiológicos, clínicos y el patrón de funcionamiento vesical según estudios urodinámicos. Clasificamos a los pacientes en 4 patrones urodinámicos según el comportamiento del detrusor y del esfínter; y lo relacionamos con la función renal en la gammagrafía y el manejo recibido desde el nacimiento. Resultados: Estudiamos 39 pacientes con mielodisplasia. El patrón vesical más frecuente fue el tipo A (61,5%) con hiperactividad del esfínter y del detrusor, seguido del D (20,5%), C (7,8%) y B (5,1%). El 38% de nuestros pacientes (n = 15) presenta algún tipo de nefropatía. El 92,9% de los niños que reciben tratamiento adecuado en el primer año de vida, no presentan lesiones renales en la gammagrafía. Encontramos algún tipo de nefropatía en el 56% de los pacientes en los que el tratamiento adecuado se demora más de un año; siendo la nefropatía más severa cuanto más tarde se inicia el manejo. Conclusiones: Existe una relación estadísticamente significativa entre el retraso en el tratamiento y la alteración en la gammagrafía renal en pacientes con vejiga neurógena. Es fundamental el estudio y tratamiento precoz de los pacientes para disminuir el deterioro renal, disminuir la necesidad de cirugía y mejorar las opciones de continencia

Objectives: Kidney failure is the main cause of morbidity and mortality in patients with myelodysplasia. We analysed the presence of renal lesions in these patients using dimercaptosuccinic acid scintigraphy and related their presence with the type of vesical function and the delay in receiving appropriate management. Material and methods: We performed a retrospective study of patients with myelodysplasia treated in our hospital since 2004. We analysed the epidemiological and clinical data and the pattern of bladder function according to urodynamic studies. We classified the patients into 4 urodynamic patterns according to detrusor and sphincter behaviour. We linked this behaviour to renal function in the scintigraphy and the care received since birth. Results: The study included 39 patients with myelodysplasia. The most common bladder pattern was type A (61.5%), with sphincter and detrusor hyperactivity, followed by type D (20.5%), C (7.8%) and B (5.1%). Some 38% of our patients (n = 15) had some type of nephropathy. Some 92.9% of the children who were properly treated during the first year of their life had no renal lesions in the scintigraphy. We found some type of nephropathy in 56% of the patients for whom appropriate treatment was delayed for more than a year. The nephropathy was more severe the later the management was started. Conclusions: There is a statistically significant relationship between a delay in treatment and impairment in renal scintigraphy in patients with neurogenic bladders. The early study and treatment of patients is essential for decreasing renal impairment, reducing the need for surgery and improving the continence options
