RESUMO

Las sibilancias recurrentes del preescolar son un problema prevalente. 50% de todos los niños tiene al menos un episodio de sibilancias en los primeros 6 años. Sin embargo, solo 4 % de los menores de 4 años tiene diagnóstico de asma. Por este motivo es fundamental realizar una adecuada anamnesis y examen físico tendientes a descartar causas secundarias, lo que debe ser complementado con exámenes de laboratorio de acuerdo con la orientación clínica. En la actualidad se recomienda indicar tratamiento de mantención con corticoides inhalados en aquellos niños que tengan episodios repetidos de obstrucción bronquial y que tengan una alta probabilidad de respuesta favorable a esta terapia. Se ha demostrado que aquellos pacientes que tienen un recuento de eosinófilos en sangre > 300 células por mm3 o aquellos que presentan una prueba cutánea positiva o IgE específicas positivas para alérgenos inhalados, responderán adecuadamente al tratamiento con esteroides inhalados.


Recurrent wheezing in preschoolers has a high prevalence. 50% of all children have at least one wheezing episode in the first six years of life. However, only 4% of children under four years of age are diagnosed with asthma. Therefore, it is essential to carry out an adequate medical history and physical examination to rule out secondary causes, which must be complemented with laboratory tests in accordance with clinical guidance. It is recommended to indicate maintenance treatment with inhaled corticosteroids to those children who have repeated episodes of wheezing and who have a high probability of a good response to this therapy. It has been demonstrated that those patients who have blood eosinophil count > 300 cells per mm3 or those who have a positive skin test or positive specific IgE for inhaled allergens will have a good response to inhaled corticosteroids.

RESUMO

Introducción: Se han informado patrones de deterioro temprano de la función pulmonar en el asma pediátrica. Nuestro objetivo fue identificar las trayectorias de la función pulmonar en la espirometría, desde la edad preescolar hasta la edad escolar. Materiales: Estudio prospectivo realizado entre el 2016 y el 2021. Se reclutaron pacientes con asma persistente a quienes se les realizó oscilometría de impulso (IOS)-espirometría al inicio y después de 3 años. La espirometría anormal se definió de acuerdo con las guías ATS/ERS. Métodos: se utilizó χ2 y ANOVA para comparar las características clínicas y promedios de parámetros de la espirometría e IOS entre trayectorias. Resultados: 86 pacientes, promedio de edad 5,3 y 8,3 años en su primera y segunda evaluación. El 70,9% de los pacientes mantuvo la espirometría normal en ambas evaluaciones (trayectoria 1), el 9,3% presentó espirometría preescolar anormal que normalizó en la edad escolar (trayectoria 2) y el 19,8% espirometría en anormal en ambas evaluaciones (trayectoria 3). La trayectoria 3 registró menor peso promedio al nacer (2,4 kg vs 3,02 kg p = 0,04), mayor promedio de exacerbaciones (5,3 vs 2,01 p = 0,00002), mayor promedio de hospitalizaciones (0,61 vs 0,16 p = 0,04), parámetros promedio más bajos en espirometría (relación VEF1/CVF %, relación VEF0,75/CVF %, VEF0,75 L, VEF0,5 L), promedios más bajos en X5 kPa/Ls y más altos en AX kPa/Ls, que la trayectoria 1. Conclusiones: La trayectoria 1 fue la más frecuente, con persistencia de función pulmonar normal. La trayectoria 3, la segunda más frecuente, inició seguimiento con función pulmonar disminuida en la espirometría y disfunción de vía aérea pequeña en el IOS que se mantuvo en la edad escolar. Los niños que siguieron la trayectoria 3 tuvieron menor peso al nacer, más exacerbaciones y hospitalizaciones que los niños de la trayectoria 1.


Introduction: Patterns of early decline in lung function have been reported in pediatric asthma. Our objective was to identify pulmonary function trajectories in spirometry, from preschool age to school age. Materials: Prospective study conducted between 2016 and 2021. Patients with persistent asthma who underwent impulse oscillometry (IOS)-spirometry at baseline and after 3 years were recruited. Abnormal spirometry was defined according to ATS/ERS guidelines. Methods: χ2 and ANOVA was used to compare clinics characteristics and means of IOS-spirometry parameters between trajectories. Results: 86 patients, mean age of 5,3 and 8,3 years in their first and second evaluation. 70.9% of the patients maintained normal spirometry in both evaluations (Track 1), 9.3% presented abnormal preschool spirometry that normalized at school age (Track 2) and 19.8% abnormal spirometry in both evaluations (Track 3). Trajectory 3 had a lower average birth weight (2,4 kg vs 3,02 kg p = 0,04), higher average of exacerbations (5,3 vs 2,01 p = 0,00002), higher average of hospitalizations (0,61 vs 0,16 p = 0,04), lowest averages parameters in spirometry (FEV1/FVC % ratio, FEV0,75/FVC % ratio, FEV0,75 L, FEV0,5 L), lower average in X5 kPa/Ls and higher in AX kPa/Ls, than trajectory 1. Conclusions: Trajectory 1 was the most common, with persistent normal lung function. Trajectory 3, the second most frequent, started follow-up with decreased lung function in spirometry and small airway disfunction in the IOS that were maintained at school age. Children who followed trajectory 3 had lower birth weight, more exacerbations, and hospitalizations than children in trajectory 1.

RESUMO

SETTING: Antenatal care (ANC) and postpartum care (PPC) clinic in Manhiça District, Mozambique.OBJECTIVE: To estimate the prevalence of TB among pregnant and post-partum women and describe the clinical characteristics of the disease in a rural area of Southern Mozambique.METHODS: We conducted a cross-sectional TB prevalence study among pregnant and post-partum women recruited from September 2016 to March 2018 at the Manhiça Health Care Center (MHC). We recruited two independent cohorts of women consecutively presenting for routine pregnancy or post-partum follow-up visits.RESULTS: A total of 1,980 women from the ANC clinic and 1,010 from the PPC clinic were enrolled. We found a TB prevalence of 505/100,000 (95% CI: 242-926) among pregnant women and 297/100,000 (95% CI: 61-865) among post-partum women. Among HIV-positive pregnant women, TB prevalence was 1,626/100,000 (95% CI: 782-2,970) and among postpartum HIV-positive women, TB prevalence was 984/100,000 (95% CI: 203-2,848).CONCLUSIONS: The burden of TB was not higher in postpartum women than in pregnant women. Most TB cases were detected in HIV-positive women. TB screening and diagnostic testing among pregnant and postpartum women attending ANC and PPC clinics in Manhiça District is acceptable and feasible.

RESUMO

La sangre normalmente transporta pequeñas cantidades de oxígeno (O2) disuelto en el plasma y altas cantidades combinadas en forma química con la hemoglobina. La presión parcial depende solo del oxígeno disuelto físicamente, lo que determina cuánto oxígeno se combinará con hemoglobina. La curva de disociación de la hemoglobina describe la reversibilidad de la reacción entre oxígeno y hemoglobina. Los factores habituales que aumentan o disminuyen la afinidad de la hemoglobina por el oxígeno son el pH, presión parcial de CO2, temperatura y 2,3 difosfoglicerato. La sangre también transporta grandes cantidades en forma de bicarbonato y bajas cantidades de CO2 disuelto en plasma y combinado con proteínas como compuestos carbamino. La desoxihemoglobina favorece la formación de compuestos carbamínicos y promueve el transporte del CO2 como bicarbonato uniéndose al hidrógeno proveniente de la disociación del ácido carbónico. A continuación se describe en forma detallada los mecanismos fisiológicos del transporte de gases en sangre.


Blood normally carries small amounts of oxygen dissolved in plasma and large amounts chemically combined with hemoglobin. Partial pressure of oxygen depends only on physically dissolved oxygen which determines how much oxygen will combine with hemoglobin. The oxygen-hemoglobin dissociation curve (or oxyhemoglobin dissociation curve) describes the reversibility of the reaction between oxygen and hemoglobin. The usual factors that increase or decrease the affinity of hemoglobin for oxygen are pH, CO2 partial pressure, temperature, and 2,3 diphosphoglycerate. Blood also carries large amounts of CO2 as bicarbonate and low amounts dissolved in plasma and combined with proteins as carbamino compounds. Deoxyhemoglobin favors the formation of carbamino compounds and promotes the transport of CO2 as bicarbonate by joining the hydrogen from the dissociation of carbonic acid. The physiological mechanisms of gas transport in blood are described in detail below.

RESUMO

INTRODUCCIÓN: El incremento del índice de masa corporal afecta la función pulmonar en el asma. Objetivo: determinar si existen diferencias entre asmáticos con estado nutricional normal, sobrepeso y obesidad en cuanto a alteraciones de la oscilometría de impulso (IOS) y espirometría. MÉTODO: Estudio realizado en niños y adolescentes con asma persistente. Se practicó sucesivamente IOS y Espirometría pre y post- broncodilatador según criterios ATS/ERS/SER. Los pacientes se clasificaron en: eutróficos (AE), con sobrepeso (ASP) y obesos (AO). Se compararon promedios de valores basales y con respuesta broncodilatadora (RB) en espirometría e IOS, con análisis de varianzas ANOVA y test de Tukey post hoc. Se consideró un poder de 80% y error α de 5%. RESULTADOS: Se analizaron 559 pacientes, promedio de edad 9,2 años, 50,9% varones. AE 52,4%, ASP 31,3% y AO 16,3%. Se encontraron diferencias significativas entre AO vs AE (X5, AX, D5-20, VEF1/CVF, FEF25-75/CVF, RB VEF1), y entre ASP vs AE (AX, D5-20, VEF1/CVF). También se encontraron diferencias significativas en varones, no encontradas en las mujeres (X5, D5-20, VEF1/CVF, RB CVF, RB VEF1). CONCLUSIONES: Los niños asmáticos con sobrepeso y obesidad, tienen un mayor compromiso de los índices de función pulmonar medida por espirometría e IOS que los asmáticos con estado nutricional normal. Existen diferencias de género en las alteraciones espirometría e IOS.


INTRODUCTION: Increased body mass index asthma affects lung function in asthma. Objective: to determine if asthmatics with overweight or obesity have alterations in Impulse oscillometry (IOS) and spirometry compared to eutrophic METHOD: Study carried out in children and adolescents with persistent asthma. IOS-Spirometry pre and post bronchodilator were performed successively according to ATS/ERS/SER criteria. The patients were classified as: eutrophic (AE), overweight (ASP) and obese (OA). Baseline and bronchodilator response (BR) averages were compared in spirometry and IOS with ANOVA and Tukey's post hoc analysis of variance. A power of 80% and α error of 5% were considered. RESULTS: 559 patients were analyzed, mean age 9.2 years, 50.9% male. AE 52.4%, ASP 31.3% and OA 16.3%. Significant differences were found between OA vs AE (X5, AX, D5-20, FEV1/FVC, FEF25-75 / FVC, RB FEV1), and between ASP vs AE (AX, D5-20, FEV1/FVC). Significant differences were also found in men, not women (X5, D5-20, FEV1/FVC, BR FVC, BR FEV1). CONCLUSIONS: Asthmatic children with overweight and obesity have a greater compromise of pulmonary function parameters measured by spirometry and IOS than asthmatics with normal nutritional status. There are gender differences in spirometry and IOS alterations.

RESUMO

Introducción: El vértigo, los mareos y el desequilibrio se encuentran entre las quejas más comunes de los adultos mayores pudiendo ocasionar repercusiones biopsicosociales como aislamiento, depresión y disminución de la autonomía. Objetivo: El objetivo del presente estudio fue determinar el impacto de la autopercepción de la discapacidad vestibular y de la sintomatología asociada sobre la calidad de vida de adultos mayores autovalentes, residentes en la comunidad y sin patología vestibular diagnosticada. Material y Método: Se realizó un estudio observacional, de alcance analítico y de corte transversal. Participaron 30 sujetos adultos mayores sanos, residentes en zonas urbanas y rurales de la Región Metropolitana. Se utilizó el dizziness handicap inventory para medir la autopercepción de dificultad vestibular y el cuestionario WHOQOL-BREF para medir calidad de vida. Resultados: Ajustando por edad, escolaridad, zona de residencia y desempeño cognitivo, el puntaje del dizziness handicap inventory predijo de manera significativa (p < 0,05) la dimensión física, psicológica y el puntaje total del WHO-QOL-BREF, explicando hasta un 35%, 9% y 16% de los puntajes, respectivamente. Conclusión: La autopercepción de la dificultad vestibular afecta significativamente la dimensión de salud física y la salud psicológica de la calidad de vida, independiente de la edad, la escolaridad, la zona de residencia y el desempeño cognitivo.


Introduction: Vertigo, dizziness and imbalance are among the most common complaints of the elderly, and can cause biopsychosocial impacts such as isolation, depression and decreased autonomy. Aim: The aim of the present study was to determine the impact of self-perception of vestibular disability and associated symptoms on the quality of life of self-reliant, community residents and without diagnosed vestibular disorders older adults. Material and Method: An observational, analytical, and cross-sectional study was carried out. Thirty healthy elderly subjects participated, residing in urban and rural areas of the Metropolitan Region. The dizziness handicap inventory was used to measure self-perception of vestibular disability and the WHOQOL-BREF questionnaire to measure quality of life. Results: Adjusting for age, schooling, area of residence and cognitive performance, the dizziness handicap inventory score significantly predicted (p < 0.05) the physical and psychological dimension and the total score of the WHOQOL-BREF, explaining up to 35%, 9% and 16% of the scores, respectively. Conclusion: The self-perception of vestibular difficulty significantly affects the dimension of physical and psychological health of quality of life, independent of age, schooling, area of residence and cognitive performance.

RESUMO

Introducción. El asma es una de las enfermedades crónicas más frecuentes en niños. Múltiples estudios han sugerido que en la infancia presenta una asociación significativa con los trastornos respiratorios del sueño, con una prevalencia en niños asmáticos de un 24%. El objetivo fue determinar la prevalencia de trastornos respiratorios del sueño (TRS) en pacientes con asma controlados en un hospital pediátrico (6-15 años). Pacientes y Método. Estudio transversal descriptivo. Se aplicaron los cuestionarios de sueño pediátrico validado en español (pediatric sleep questionnaire, PSQ) y el Cuestionario de Control del Asma en Niños (CAN) a los padres de los niños con diagnósticos de asma controlados en Hospital Roberto del Río, vía telefónica y vía email. Resultados: La prevalencia de TRS fue de 34,8%. Un 20% presenta mal control de asma definido como CAN >8. Un 58,1% de los padres reportaron sobrepeso en los pacientes Conclusiones: la prevalencia de TRS en los niños estudiados es alta y obliga a investigar en cada consulta por estos síntomas. Aplicar la encuesta en cada consulta, de forma online podría aportar al conocimiento de estos pacientes y mantener la prevalencia del problema actualizada, para focalizar las intervenciones apropiadas.

RESUMO

La osificación heterotópica (OH), es la formación anormal de hueso maduro dentro de tejidos blandos extra esqueléticos donde normalmente no existe tejido óseo. Varias formas de OH han sido descritas de acuerdo a su presentación clínica, localización y ocurrencia progresiva o aislada. Su presentación en pacientes sometidos a inmovilización prolongada en el contexto de coma farmacológicamente inducido, en ausencia de lesiones del sistema nervioso central, es poco habitual. Presentamos el caso de una paciente de 40 años, sexo femenino, sin antecedentes mórbidos, que presenta episodio de pancreatitis aguda grave, manejada en UCI. Producto de lo anterior, requiere coma farmacológicamente inducido por 3 meses y hospitalizaciones reiteradas y prolongadas durante los 10 meses siguientes. Durante 3 años desde la resolución de su cuadro inicial evoluciona con alteración progresiva de la marcha y rigidez de la extremidad inferior derecha, sin eventos traumáticos durante ese período. Se objetiva mediante radiografía y TAC foco de OH coxofemoral derecha. Se resuelve de forma quirúrgica y biopsia de pieza operatoria confirma el diagnóstico. La paciente logra buena recuperación posterior. NIVEL DE EVIDENCIA: IV


Heterotopic ossification (HO) is the abnormal formation of mature bone within extraskeletal soft tissues where bone does not exist. Various presentation of HO have been described according to the clinical settings and location of the lesions, and progressive or isolated occurrence. A rare form of presentation occurs in induced coma patients with long-term immobilization and without central nervous system injuries. We present the case of a 40 years old female patient, without previous morbidity, who develop a severe acute pancreatitis. The patient requires an intensive care unit management (ICU) and a 3-month pharmacology induced coma and reiterative and prolonged hospitalizations during the next 8 months. During 3 years after resolution of her base disease, patient develops a progressive step claudication and a hip rigidity in adduction and external rotation. A coxofemoral HO focus is confirmed by radiology and CT. A surgical treatment of HO was performed, and the initial diagnose confirmed by anatomic pathology after biopsy of the injury. Patient had a favorable outcome.

RESUMO

The goals of the End TB strategy, which aims to achieve a 90% reduction in tuberculosis (TB) incidence and a 95% reduction in TB mortality by 2035, will not be achieved without new tools to fight TB. These include improved point of care (POC) diagnostic tests that are meant to be delivered at the most decentralised levels of care where the patients make the initial contact with the health system, as well as within the community. These tests should be able to be performed on an easily accessible sample and provide results in a timely manner, allowing a quick treatment turnaround time of a few minutes or hours (in a single clinical encounter), hence avoiding patient loss-to-follow-up. There have been exciting developments in recent years, including the WHO endorsement of Xpert MTB/RIF, Xpert MTB/RIF Ultra, loop-mediated isothermal amplification (TB-LAMP) and lateral flow lipoarabinomannan (LAM). However, these tests have limitations that must be overcome before they can be optimally applied at the POC. Furthermore, worrying short- to medium-term gaps exist in the POC diagnostic test development pipeline. Thus, not only is better implementation of existing tools and algorithms needed, but new research is required to develop new POC tests that allow the TB community to truly make an impact and find the "missed TB cases".

RESUMO

SETTING: Mozambique, one of the world's high tuberculosis (TB) burden countries, has conducted only one national-level drug resistance survey, in 2007-2008. OBJECTIVE: To determine the drug resistance patterns of laboratory-confirmed TB cases. DESIGN: This was a population-level survey conducted over a 1-year period in the district of Manhiça. All laboratory-confirmed cases were evaluated for first-line anti-tuberculosis drug susceptibility testing using liquid culture. RESULTS: Resistance to at least one first-line drug was observed in 44 of 276 isolates (15.9%). Prevalence of drug resistance to each of the five anti-tuberculosis drugs tested was 4.0% for streptomycin, 10.1% for isoniazid (INH), 6.2% for rifampicin, 3.6% for ethambutol and 1.1% for pyrazinamide. The overall prevalence of multidrug-resistant TB (MDR-TB) was 5.1%: 3.8% (95%CI 2.0-7.0) in new and 13.2% (95%CI 5.8-27.3) in retreatment cases. Respectively 4.6% and 2.6% of new and retreatment cases were INH-monoresistant. Previous history of anti-tuberculosis treatment was associated with having MDR-TB (OR 4.3, 95%CI 1.3-14.1). CONCLUSION: The prevalence of drug resistance in the district of Manhiça is slightly higher than, but still compatible with, previous national estimates. INH monoresistance was high, posing the risk of hidden monotherapy in the continuation phase.

RESUMO

Background: Type 1 diabetes mellitus and celiac disease share common genetic and immunological aspects and celiac disease is more common among type 1 diabetic patients. Aim: To determine the frequency of anti endomysial and anti transglutaminase antibodies among patients with type 1 diabetes. Material and Methods: Anti endomysialantibodies determined by indirect immunofluorescence an anti transglutaminase antibodies determined by ELISA were measured in 410 serum samples of patients with type 1 diabetes. Results: Seventy one samples (17 percent) had positive anti transglutaminase antibodies. Among these, 17 had also positive anti endomysial antibodies. In 11 of these 17 patients, the presence of celiac disease was confirmed. Conclusions: Among patients with type 1 diabetes mellitus, the frequency of celiac disease is three times higher than in the general population.

RESUMO

El síndrome de Lemierre es una complicación muy poco frecuente de una infección orofaríngea, que progresa con tromboflebitis séptica secundaria e infecciones embólicas frecuentes. Presentamos el caso de una mujer de 20 años que inició un cuadro de odinofagia y fiebre, el cual progresó rápidamente a un absceso periamigdalino con trombosis de la vena yugular interna ipsilateral, embolias sépticas pulmonares y meningitis. Se manejó con drenaje del absceso por punción, terapia antibiótica de amplio espectro y anticoagulación respondiendo favorablemente, siendo dada de alta en buenas condiciones luego de 35 días de hospitalización. Con la terapia antimicrobiana, casos como éste son poco frecuentes, incluso a veces olvidados, pero dado su gravedad deben considerarse en cuadros faríngeos de evolución tórpida o ante la aparición de signos neurológicos o sépticos.


Lemierre syndrome is a rare complication of oropharyngeal infection which progresses with secondary septic thrombophlebitis and embolic infections. A 20 years-old woman started with odynophagia and fever, which progressed rapidly to a peritonsillar abscess with thrombosis of the ipsilateral internal jugular vein, septic pulmonary emboli and meningitis. She was managed with abscess drainage puncture, broad-spectrum antibiotic therapy and anticoagulant responding favorably, and was discharged in good condition after 35 days of hospitalization. Since the use of antimicrobial therapy, cases like these are rare, sometimes forgotten, but given its severity should be considered in pharyngeal torpid illness or at the onset of neurological signs or sepsis.

RESUMO

BACKGROUND: The bioequivalence of different formulations of a same pharmaceutical product must be tested empirically. AIM: To evaluate the relative bioavailability for an oralformulation of mycophenolate mofetil (MMF) (Linfonex™) compared to the reference formulation (Cellcept™) to determine the bioequivalence between both formulations. MATERIAL AND METHODS: A randomized, crossover, double-blind trial in 22 healthy male volunteers, who received a single oral dose of 1000 mg of Linfonex and Cellcept with a washout period of 10 days. Plasma levels of the drug were determined by high performance liquid chr ornatography. Plasma concentrations were plotted and maximum concentration, area under the plasma concentration versus time between 0 and 12 hours after administration and área under plasma concentration curve versus time after administration between 0 and infinity, were calculated for both products. RESULTS: The active compound, mycophenolic acid, was similarly absorbed in both formulations. No statistically significant differences were found in calculated pharmacokinetic parameters between both formulations. CONCLUSIONS: Linfonex™ 500 mg is bioequivalent to Cellcept™ 500 mg.

RESUMO

Introduction: Adenovirus infection is an important cause of pneumonia in Chilean children. Postinfectious Bronchiolitis Obliterans (PIBO) is the most important complication. There are few studies assessing pulmonary function and quality of life in PIBO patients. Objective: The aim of this study is to assess the pulmonary function and the quality of life of patients with PIBO and the correlation between both variables. Methods: 14 children with PIBO in follow up at the pediatric pulmonology outpatient clinic of a public children hospital were included in this study. Study period: April 2009 - April 2010. Pulmonary function was assessed in a medical visit by spirometry, flow/volume curve and intrathoracic gas volume measurement. The following indices were analyzed FVC, FEV1, FEV25-75, FEV1/FVC, RV, TLC, RV and RV/TLC. A survey of a self-administered Quality of Life (PedsQL, version 4.0, Spanish for Chile) was applied at the visit to investigate their global, physical and psychosocial quality of life. The Pearson linear correlation between quality of life and the pulmonary function test parameters was assessed, in the statistical analysis ap value < 0.05 was considered significant. Results: The mean age of our patients was 12.4 (range: 9-19 years-old). The functional alterations were characteristics of an obstructive respiratory disorder in 64.3 percent of the patients. Average pulmonary function test indices showed decreases in FEV1 (75 percent), FEV25-75 (48.8 percent), FEV1/FVC (67.6 percent) with normal value of FVC (93,7 percent) as well as pronounced increases in RV (333.5 percent), TLC (156 percent) and RV/TLC (51.8 percent). Mean change of FEV1 and FEV25-75post-bronchodilator was 11.3 percent and 26.4 percent respectively. Only 14.3 percent of our patients showed normal pulmonary function. The quality of life parameters were in average 58.2 percent of overall quality of life, 58.6 percent of physical quality of life and 57.9 percent of psychosocial ...


Introducción: La infección por adenovirus es una causa importante de neumonía en niños chilenos. La bronquiolitis obliterante (BOPI) es la complicación más importante. Existen pocos estudios donde evalúen la función pulmonar y la calidad de vida de los pacientes con BOPI. Objetivo: Evaluar la función pulmonar y la calidad de vida de los pacientes con BOPI y la correlación entre ambas variables. Métodos: Se incluyeron 14 niños con BOPI en el policlínico de la unidad de broncopulmonar de un hospital público de niños. Período de estudio: abril de 2009-abril de 2010. La función pulmonar se evaluó en una visita médica por espirometría, curva flujo / volumen y la determinación de volumen de gas intratorácico. Los índices analizados fueron los siguientes CVF, VEF1, FEV25-75, VEF1/CVF, VR,CPT, VR y VR / CPT. En la misma visita se realizó una encuesta auto-administrada de Calidad de Vida (PedsQL, versión 4.0, español de Chile) para investigar la calidad de vida global, física y psi-cosocial. Se aplicó la correlación lineal de Pearson entre calidad de vida y los parámetros de función pulmonar. Se consideró estadísticamente significativo unp <0,05. Resultados: La edad media de nuestros pacientes fue de 12,4 (rango: 9-19 años). La alteración funcional característica fue la obstructiva en el 64,3 por ciento de los pacientes. El promedio de los índices de pruebas de función pulmonar mostraron una disminución en VEF1 (75 por ciento), FEV25-75 (48,8 por ciento), VEF1/CVF (67,6 por ciento) con un valor normal de la CVF (93,7 por ciento), así como aumentos pronunciados en VR (333,5 por ciento), CPT (156 por ciento) y VR/CPT (51,8 por ciento). La media del cambio del VEF1 y FEV25-75post-broncodilatador fue 11,3 por ciento y 26,4 por ciento respectivamente. Sólo el 14,3 por ciento mostró una función pulmonar normal. Los parámetros de calidad de vida fueron en promedio 58,2 por ciento de calidad de vida general, 58,6 por ciento de calidad de vida física y el 57,9 por ciento...

RESUMO

Introducción: Algunos niños asmáticos presentan exacerbaciones que motivan su ingreso a Unidad de Paciente Crítico (UPC). A nivel nacional no existen publicaciones al respecto. El objetivo del estudio fue conocer las características clínicas de los niños con crisis asmáticas que requieren manejo en UPC en el Hospital Roberto del Río. Pacientes y Método: Estudio retrospectivo, descriptivo en mayores de 4 años, egresados de UPC con diagnóstico de crisis de asma en un período de tres años. Resultados: 67 niños requirieron manejo en UPC El promedio de edad fue 7 años y el de hospitalización 4 días. En 59 pacientes se utilizó Ventilación Mecánica No Invasiva (VMNI). Del total de pacientes sólo 27 tenía diagnóstico previo de asma, observándose buena adherencia al tratamiento sólo en 7. Conclusiones: Sólo el 40 por ciento de los pacientes asmáticos tenían el diagnóstico de asma antes de la hospitalización y la mayoría de ellos presentaba una pobre adherencia al tratamiento. En el manejo destaca un alto porcentaje de uso de VMNI.


Introduction: Some asthmatic children present severe exacerbations, demanding hospitalization in the Pediatric Intensive Care Unit (PICU). On a national Chilean scale, there is no published data about these patients. The objective of this study was to evaluate the clinical features of children with asthmatic exacerbations requiring PICU management at Roberto del Río Children's Hospital in Santiago de Chile. Patients and Method: Retrospective and descriptive study in children above 4 years of age discharged from PICU with diagnosis of asthmatic exacerbation during a three years period. Results: 67 children required treatment in PICU. The average of age was 7 years old, while the average of hospital stay was 4 days. Non invasive ventilation (NIV) was used in 59 patients. Only 27 patients had previous diagnosis of asthma, with good treatment adherence only in 7 of them. Conclusions: Before being hospitalized, only 40 percent of the asthmatic patients were diagnosed as asthmatic and most of them had a bad treatment compliance. NIVwas used in a remarkably high percentage of these patients.

RESUMO

Pharmacokinetics corresponds to the branch of pharmacology that studies the absorption, distribution, biotransformation and excretion of drugs in the body, in order to proportionate a reference line for interpretation of drug concentration in biological fluids, fundamental for clinical therapy. While adult pharmacology has increase greatly, advances in pediatric pharmacology have been poor. Therefore, drug prescription in children is essentially empirical on the basis of an inmature organism. An effective, secure and rational pediatric pharmacology requires exhaustive knowledgement of the developmental changes in relation to absorption, distribution, metabolism and excretion affecting pharmacokinetics parameters; therefore, the effective dose. This review describes fundamental differences between adult and pediatric pharmacokinetics. These differences must be considered when therapeutic strategies develop for newborns and children.


La farmacocinética, rama de la farmacología que estudia el paso de las drogas a través del organismo en función del tiempo y la dosis tiene por finalidad el proporcionar un marco de referencia para interpretar la concentración de los fármacos en los líquidos biológicos por el bien del paciente, lo que es fundamental para una correcta terapéutica clínica. Mientras los avances en farmacología clínica del adulto en las últimas décadas tuvieron un gran adelanto, no ha ocurrido lo mismo en farmacología pediátrica donde la mayoría de las veces la prescripción de medicamentos se realiza sobre una base empírica en un organismo inmaduro. Una terapéutica farmacológica efectiva, segura y racional en neonatos, lactantes y niños requiere el exhaustivo conocimiento de las diferencias en la absorción, distribución, metabolismo y excreción, las que aparecen durante el crecimiento y desarrollo, debido a que virtualmente, todos los parámetros farmacocinéticos se modifican con la edad. Esta revisión describe las diferencias fundamentales en la farmacocinética de los medicamentos en el niño cuando se compara con el adulto. Estas diferencias y los cambios en estos procesos deben ser cuidadosamente considerados cuando se desarrollan estrategias terapéuticas en recién nacidos y niños pequeños.

RESUMO

INTRODUCTION: Airway management in patients with middle third facial skeleton fractures is a challenge for anesthesiologists and surgeons, given that the natural routes for intubation--the nose and mouth--are both compromised by trauma. In this setting, the airway can only be accessed by tracheotomy. Tracheotomy, however, is an invasive technique that should be reserved for cases in which it is absolutely necessary. OBJECTIVES: To establish the utility of submental intubation as an alternative to tracheotomy in patients with middle third facial skeletal fractures. PATIENTS AND METHODS: We reviewed the cases of the 15 patients intubated with the aforementioned technique between 1996 and 2002 in Hospital Universitario La Paz in Madrid, Spain. We describe the surgical technique and postoperative course recorded for those patients. RESULTS: The courses of surgery and postoperative recovery were without complications. All extubations were uneventful and no patient required a tracheotomy. CONCLUSIONS: Submental intubation is a simple, useful technique for managing the airway of patients with middle third facial skeletal fractures. The technique has few complications.

RESUMO

Objetivos: Comparación de la eficiencia de tres técnicas de analgesia epidural para tratamiento del dolor postoperatorio en niños: tratamiento con analgesia epidural con bolos de morfina cada 8 horas (grupo MB), analgesia epidural continua con una mezcla de lidocaína y fentanilo (grupo PC) o analgesia epidural administrada a través de una bomba de PCA de lidocaína y fentanilo (grupo PCA).Métodos: Estudio económico predictivo sobre una hipotética cohorte de 250 individuos pediátricos afectados por dolor postoperatorio moderado-severo en un Hospital de Tercer Nivel. Se aplicaron los precios de mercado a los costes asociados a cada técnica. Se calcularon los ratios coste/efectividad con los datos sobre seguridad y efectividad de cada técnica publicados en la literatura y los obtenidos en el estudio. Resultados: Los costes totales asociados a cada técnica fueron superiores en el grupo PCA (5.353 euros) y PC (5.046,7 euros) comparado con el grupo MB (3.249,8 euros), sin embargo, la mayor efectividad del grupo PCA (220 pacientes) frente al grupo PC (145 pacientes) o el MB (104 pacientes) provocó que el coste por tratamiento adecuado fuese netamente menor en el grupo PCA (24,33 euros/paciente) que en el grupo PC (32,14 euros/paciente) o el MB (32,25 euros/paciente). Conclusiones: La introducción de una nueva tecnología como la PCA en el tratamiento del dolor postoperatorio pediátrico supone un encarecimiento del servicio asistencial prestado. La pertinente evaluación económica de dicha tecnología permitió demostrar que dicho encarecimiento se tradujo en un claro beneficio de los pacientes tratados con una mayor eficiencia (AU)
