[Comparison between conventional ph measurement and multichannel intraluminal esophageal impedance in children with respiratory disorders]. / Comparación entre pH-metría convencional e impedanciometría intraluminal multicanal en niños con patología respiratoria.

INTRODUCTION: Gastroesophageal reflux (GER) is associated with respiratory symptoms. The link between non-acid GER and the pathogenesis of respiratory disease has been demonstrated. Esophageal multichannel intraluminal impedance (MII) is able to detect non-acid and alkaline GER, as well as reflux height. The objective of the study was to compare the diagnostic effectiveness of dual-channel pH-meter and MII. PATIENTS AND METHODS: A prospective study was conducted on patients diagnosed with uncontrolled asthma, persistent cough, or chronic laryngitis. Patients were monitored continuously for 24 hours using a combination of MII and a dual-channel pH-meter. A descriptive and comparative analysis of the techniques was performed using the t test for comparison between groups and McNemar test for non-parametric data. RESULTS: A total of 49 patients with respiratory disease between September 2008 and April 2010 (79.6% uncontrolled asthma, 10.2% persistent cough, and 10.2% chronic laryngitis) were included in the study. The mean number of refluxes detected was 18.3 (range 0-93) using the pH-meter and 39.2 (11-119) using MII (P<.001). Acid GER was detected using pH in 7 children and using MII in 25 children (8 acid, 10 alkaline and 7 mixed). A mean of 21 proximal refluxes were detected using MII. CONCLUSIONS: MII makes it possible to diagnose a greater number of refluxes, whether acid or alkaline, than conventional pH measurement in children with respiratory disease that is poorly controlled with their usual treatment. MII can also detect proximal refluxes.

Comparación entre pH-metría convencional e impedanciometría intraluminal multicanal en niños con patología respiratoria / Comparison between conventional ph measurement and multichannel intraluminal esophageal impedance in children with respiratory disorders

Introducción: El RGE se asocia a sintomatología respiratoria; se ha demostrado la relación entre el RGE no ácido y su etiopatogenia. La impedancia intraluminal multicanal esofágica (MII) es capaz de detectar RGE no ácido y alcalino, así como la altura de ascenso del reflujo. Objetivo: Comparar la eficacia en el diagnóstico de reflujo gastroesofágico ácido y no ácido de la pH-metría bicanal y la MII en pacientes con patología respiratorio. Pacientes y métodos: Estudio longitudinal, prospectivo de pacientes con diagnóstico de asma persistente al tratamiento, tos crónica o laringitis de repetición. Se realizó monitorización continua durante 24 h mediante MII-pH-metría doble canal y análisis descriptivo de los datos comparando ambas técnicas entre sí. Se realizó un análisis descriptivo y comparativo mediante la prueba de la t de Student y el test de MacNemar como prueba no paramétrica. Resultados: Entre septiembre 2008 y abril 2010 se incluyó a 49 pacientes con patología respiratoria (79,6% asma crónica, 10,2% tos crónica y 10,2% laringitis). La media de reflujos detectados por pH-metría fue de 18,3 (rango 0-93) y por MII de 39,2 (11-119) (p<0,001). El índice sintomático fue 6,7% por pH-metría y 13,9% por MII (p<0,05). El número de niños diagnosticados de RGE ácido por pH-metría fue de 7 y mediante MII se diagnosticaron 25 niños (8 ácidos, 10 alcalinos y 7 mixtos). La media de reflujos proximales detectados por MII fue de 21. Conclusiones: La MII es capaz de diagnosticar mayor número de reflujos tanto ácidos como alcalinos que la pH-metría convencional en los niños con patología respiratoria resistente al tratamiento, así como detectar reflujos proximales(AU)

Pericarditis recurrente secundaria a un quiste pericárdico / Recurring secondary pericarditis due to pericardial cyst

Los procesos expansivos intratorácicos son infrecuentes en la infancia, y se localizan habitualmente en el mediastino. La escasa expresión clínica inicial condiciona un diagnóstico tardío y dificulta el tratamiento efectivo. Se clasifican según la localización topográfica (anterior, media o posterior), lo que permite establecer una orientación diagnóstica basada en las estructuras de cada compartimento. La patología tumoral es la más frecuente, aunque no hay que descartar la etiología infecciosa o malformativa (quística-vascular) y la patología tiroidea opericárdica, como el caso que motiva esta publicación. La radiografía de tórax es la técnica diagnóstica inicial, aunque generalmente se requiere la realización de una tomografía computarizada (mediastino anterior y medio) o una resonancia magnética (mediastino posterior), que localizan y delimitan la lesión e informan de su consistencia y contenido. La ecografía es coste efectiva, no invasiva, está libre de radiación y permite evaluar el timo o el pericardio. Las masas pericárdicas son infrecuentes, generalmente congénitas, aunque pueden tener un origen inflamatorio; su tratamiento es conservador, y está indicada la cirugía si el tamaño es grande o la sintomatología persistente(AU)

The intrathoracic expansive mass are infrequent during infancy, being the common localization the mediastinic, the scarce clinical expression conditions to a late diagnosis obstructing the effective treatment. They are classified according to topographic localization (front, middle or back) allowing a diagnosis orientation based on the structures of each compartment. The tumoral pathology is the most frequent, not being despised the infectious etiology, malformative (cystic or vascular), the thyroid pathology or pericardial, as the case, which this articleis based on. The thorax x-ray is the initial diagnosis technique, although generally a cat scan is needed of the (front mediastinum or middle) or a magnetic resonance (back mediastinum)that localizes and defines the lesion, informing of the consistency and context. The ecography is cheap not invasive, radiation free and allows evaluating the thymus and pericardium. The pericardial masses are infrequent, generally congenital, although they might have an inflammatory origin; its treatment is conservative, surgery is indicated if the size is big or the group of symptoms is persistent(AU)
