ABSTRACT
Desde la aparición de la pandemia por SARS-CoV-2, la población pediátrica ha sido menos afectada por la enfermedad tanto en frecuencia como en severidad. Sin embargo, desde abril de este año se han reportado casos de presentación y gravedad variables, caracterizados por fenómenos inflamato rios que afectan múltiples órganos, condición denominada Síndrome Inflamatorio Multisistémico Pediátrico (PIMS). La literatura describe frecuente compromiso cardíaco, hasta en un 80%. Este se caracteriza por injuria miocárdica con significativa elevación de biomarcadores: Troponinas séricas I/T, BNP o NT-ProBNP, unido a diversos grados de disfunción ventricular, pericarditis, valvulitis y arritmias. Además, se ha evidenciado la presencia de compromiso coronario el cual puede ocurrir hasta en un 23% de los casos, en un rango que va desde dilataciones hasta aneurismas. El seguimien to cardiológico hospitalizado y ambulatorio se ha sistematizado en base a los fenotipos clínicos de presentación: injuria miocárdica (miocarditis, valvulitis, pericarditis), shock (habitualmente de tipo "vasopléjico"), manifestaciones tipo Enfermedad de Kawasaki y aquellos casos PIMS que no cumplen con la clínica de los tres precedentes. Este último grupo es el que representa el mayor desafío en el cor to, mediano y seguimiento a largo plazo. Por esta razón se requiere un equipo multidisciplinario para su manejo. Considerando la alta frecuencia del compromiso cardíaco en el PIMS y la importancia de lograr un consenso en su manejo y seguimiento, se presentan estas recomendaciones según el estado actual del conocimiento de esta patología recientemente descrita.
Since the onset of the SARS-CoV-2 pandemic, the pediatric population has been less affected by the disease both in frequency and severity. However, since April cases of variable presentation and severity characterized by inflammatory phenomena that affect multiple organs have been reported, a condition called Multisystem Inflammatory Syndrome in Children (MIS-C). The literature has reported frequent cardiac involvement, up to 80%. This is characterized by myocardial injury with a significant increase of biomarkers such as serum troponins I and T, BNP, or NT-ProBNP coupled with varying degrees of ventricular dysfunction, pericarditis, valvulitis, and arrhythmias. Coronary compromise has also been described, which can occur in up to 23% of cases, and ranges from dila tations to aneurysms. Inpatient and outpatient cardiology follow-up has been systematized based on the clinical phenotypes such as myocardial injury (myocarditis, valvulitis, pericarditis), shock (usua lly vasoplegic), Kawasaki disease-type manifestations, and those MIS-C that do not comply with the clinic of the previous three. This last group represents the main challenge in the short-, medium- and long-term follow-up, therefore, it is necessary a multidisciplinary team for managing these patients. Considering the high frequency of cardiac compromise in MIS-C, and the importance of reaching a consensus regarding its management and follow-up, we present these recommendations according to the current state of knowledge regarding this recently described pathology.

INTRODUCTION: Tetralogy of Fallot (TOF) is the most frequent cyanotic congenital heart disease. Pulmonary regurgitation (PR) and right ventricle (RV) enlargement and dysfunction are the most common long-term complications. Cardiac magnetic resonance (CMR) is the gold standard for RV evaluation. OBJECTIVE: To analyze CMR results in the follow-up of TOF patients. PATIENTS AND METHOD: All CMR performed between 2007 and 2012 in TOF patients with transannular patch (TAP) repair or infundibular widening, and without pulmonary valve replacement (PVR) were included. Pulmonary regurgitant fraction (PRF), ventricular end-diastolic (EDV) and end-systolic volume (ESV), and ejection fraction (EF) were examined. RESULTS: 122 CMR were performed in 114 patients. Average age at CMR was 15.4±7.4 years. 53.3% of them presented severe PR (> 40%). RVEDV was 157.3 ± 38.6 ml/m2, RVESV was 85.3 ± 27 ml/m2 and RVEF was 46.4 ± 7.1%. RVEDV was > 150 ml/ m2 in 48.4% and > 170 ml/m2 in 32.8% of patients. Patients with TAP showed larger RV volumes compared with those with infundibular widening. RVEDV > 170 ml/m2 showed worse RVEF that those with lower RVEDV (47.9 ± 7% vs 43.2 ± 6.4%, p < 0.01). CONCLUSION: Almost half of the pa tients showed significant RV enlargement, demonstrating that the indication of CMR is late in their follow-up. TAP was associated with higher RVEDV and RVESV, but no worse RVEF.

INTRODUCCIÓN: La tetralogía de Fallot (TF) es la cardiopatía congénita cianótica más frecuente. La insuficiencia pulmonar (IP) y dilatación del ventrículo derecho (VD) son las complicaciones más frecuentes a largo plazo. La resonancia magnética cardiaca (RMC) es el "gold standard" para la evaluación del VD. OBJETIVO: Analizar la información obtenida de las RMC en el seguimiento de pacientes con TF. PACIENTES Y MÉTODO: Se incluyeron RMC realizadas entre 2007 y 2012 a pacientes con TF, reparados con parche transanular (PTA) o ampliación infundibular (AInf) y sin recambio valvular pulmonar (RVP). La fracción de regurgitación pulmonar (FRP), el volumen y función ventricular fueron evaluados. RESULTADOS: Se realizaron 122 RMC a 114 pacientes. Edad promedio al examen 15,4 ± 7,4 años. 53,3% presentó IP severa (> 40%). La media del volumen de fin de diástole del VD (VFDVD) fue 157,3 ± 38,6 ml/m2, fin de sístole (VFSVD) de 85,3 ± 27 ml/m2 y fracción de eyección (FEVD) 46,4 ± 7,1%. 48,4% presentaba un VFDVD mayor de 150 ml/m2 y el 32,8% mayor a 170 ml/ m2. El PTA se relacionó con mayores volúmenes de VD que la AInf. VFDVD mayor a 170 ml/m2 mostraron peor FEVD (FEVD 47,9 ± 7% vs 43,2 ± 6,4%, p < 0,01). DISCUSIÓN: Casi la mitad mostró una significativa dilatación del VD demostrando que la indicación de RMC es tardía en el seguimiento. El PTA se asoció con mayores VFDVD y VFSVD pero no a peor FEVD.

BACKGROUND: Lactose intolerance is a frequent condition in certain populations. Different methods for diagnosis exist. There is scarce literature regarding Lactose Quick Test (LQT) and concordance with other methods for lactose intolerance diagnosis in children. METHODS: Prospectively, we included children who underwent gastroduodenoscopy for evaluation of abdominal pain. We obtained a duodenal sample for LQT and blood sample for genetic test to evaluate LCT C>T-13910 variant. Later, patients underwent breath test with lactose, to evaluate malabsorption. We evaluated the concordance between the three different tests. KEY RESULTS: We included 46 patients, 56.5% women. Mean age was 13.2 years (range 9-18 years). 66.6% of patients had lactose malabsorption according to breath test; 64.4% were homozygous CC; and 91.3% had hypolactasia (mild or severe) according to LQT. None of the patients with normolactasia had altered breath test. Genetic test had a substantial agreement (k = 0.675) with breath test and fair agreement (k = 0.301) with LQT. LQT had fair agreement (k = 0.348) with breath test. CONCLUSIONS & INFERENCES: Genetic test had better concordance with breath test than LQT to diagnose lactose malabsorption, however, none of the patients with normal LQT had lactose malabsorption. In patients who undergo gastroduodenoscopy to study abdominal pain, it seems reasonable to perform LQT, and, in those with hypolactasia, to perform breath test.

A multiplex (m-)PCR-based protocol was designed for the simultaneous detection of the main marine bacterial pathogens in Chilean salmon farms: Streptococcus phocae, Aeromonas salmonicida, Vibrio anguillarum and Piscirickettsia salmonis. Each of the 4 oligonucleotide primer pairs exclusively amplified the target gene of the specific bacterial pathogen. The detection limit of the m-PCR using purified total bacterial DNA was 50 pg microl(-1) for V anguillarum, 500 fg microl(-1) for P. salmonis, and 5 pg microl(-1) for S. phocae and A. salmonicida. This corresponded to average limits in the m-PCR sensitivity of 3.69 x 10(5) CFU ml(-1) of V anguillarum, 1.26 x 10(4) CFU m(-1) of S. phocae, and 5.33 x 10(4) CFU ml(-1) of A. salmonicida, while the detection limits for the spiked fish tissues, regardless of the sample (spleen, kidney, liver or muscle) were 2.64 +/- 0.54 x 10(7) CFU g(-1) for V. anguillarum, 9.03 +/- 1.84 x 10(5) CFU g(-1) for S. phocae, 3.8 +/- 0.78 x 10(3) CFU mg(-1) for A. salmonicida and 100 P. salmonis cells. However, high amounts of DNA from 3 bacterial species had a reduction of -1 log-unit on the amplification sensitivity of S. phocae or A. salmonicida when these were present in lower concentration in the multiplex reaction. The assay described in this study is a rapid, sensitive and efficient tool to detect the presence of S. phocae, A. salmonicida, V. anguillarum and P. salmonis simultaneously from pure cultures and tissues from clinically diseased fish. Therefore, it may be a useful alternative to culture-based methods for the diagnosis of infections in fish obtained from Chilean salmon farms.

Introducción: El empiema pleural (EP) es una complicación grave de la neumonía adquirida en la comunidad (NAC). Objetivos: Describir las características de los pacientes hospitalizados por EP en el Servicio de Pediatría del Hospital de la Universidad Católica durante el período 2000-2005. Se identificaron 86 hospitalizaciones por NAC con efusión pleural, practicándose en 59 (70 por ciento), al menos una toracocentesis. Se consideró EP a la presencia de pus, tinción de Gram con bacterias, cultivo positivo o pH < 7,10 en el líquido pleural, siendo las efusiones para-neumónicas los controles. Resultados: Se analizaron 24 EP y 25 controles [promedio 2,9 años (rango: 8 meses - 14,3 años)], 78 por ciento de edad inferior a 5 años con diferencia entre los grupos EP y controles [1,6 vs 3,3 años, respectivamente (p = 0,01)]. El promedio global (días) de síntomas previo al ingreso en los EP fue 7 (rango: 2-21), siendo los más frecuentes fiebre (100 por ciento) y tos (96 por ciento). Se identificó algún microorganismo en 15/24 EP, Streptococcus pneumoniae fue el más frecuente (n: 9). En 48 niños, el manejo inicial fue conservador, requiriéndose cuatro rescates quirúrgicos luego del cuarto día. El promedio (días) de hospitalización fue significativamente superior en el grupo EP vs controles [15 (rango: 5-38) vs 9 (rango: 3-16) (p < 0,01)]. Requirieron drenaje pleural 83 por ciento del grupo EP y 36 por ciento de los controles (p = 0,002). No hubo diferencia en el número de días de empleo de oxígeno [6 vs 4,5 (p = 0,36)] o drenaje pleural [3 vs 2,5 (p = 0,29)]. No se registraron fallecidos. Conclusión: El EP en niños fue una condición respiratoria aguda que se asoció a estadías hospitalarias prolongadas, especialmente en los de menor edad, no requiriéndose, en la mayoría, una intervención quirúrgica de rescate.
Introduction: Pleural empyema (PE) is a serious complication of community-acquired pneumonia (CAP). Objectives: To describe the clinical profile of hospitalized patients with PE in the pediatric ward of the Catholic University Hospital between 2000-2005. Patients y methods: Retrospectively, all pediatric admission due to CAP and pleural effusion (86 children) were identified. In 59 (70 percent) children > 1 thoracocentesis were performed. We considered PE as the presence in the pleural effusion of pus, and/or a positive gram strain and/ or positive culture, and/or a pH < 7.10. Children with effusions not meeting any criteria were used as controls. Results: Twenty four PE and 25 controls were identified, with a global mean age of 2.9 years (range: 8 months to 14.3 years); 78 percent were < 5 years, with a significant difference between PE and controls [1.6 vs 3.3 years (p = 0.01)]. The mean duration of symptoms in PE patients before admission was 7 days (range: 2-21), and the most frequent symptoms were fever (100 percent) and cough (96 percent). In 15/24 cases a microorganism was identified being Streptococcus pneumoniae (n = 9) the most common. In 48 patients management was conservative and in 4 surgical procedures were required. The mean duration of hospitalization was significantly higher in the PE group vs controls group: 15 (range: 5-38) vs 9 days (range 3-16) (p < 0.01). A chest tube was inserted in 83 percent of children with EP compared with 36 percent in the control group (p = 0.002). There were no difference in number of days of oxygen use [6 vs 4.5 (p = 0.36)] or number of chest tubes per child [3 vs 2.5 (p = 0.29)]. No deaths were reported. Conclusion: PE in children represented an acute respiratory event associated with more prolonged hospitalization especially at younger ages; the majority of cases did not require surgical intervention.

El cortisol plasmático guarda correlación con la severidad y duración del estado crítico, y el papel de la Dehidroepiandrosterona sulfato (DHEA-S) no ha sido identificado claramente. El paciente crítico muestra una activación máxima inicial del eje suprarrenal, si la situación crítica se prolonga, se puede producir una insuficiencia suprarrenal relativa. Midiendo cortisol y DHEA-S durante la noche de las 24 primeras horas críticas se podría hacer más evidente esta insuficiencia resultando una mejor correlación entre estas hormonas, APACHE II y mortalidad. Diseño: Estudio observacional en pacientes críticos de la UTI del Hospital de Urgencia Asistencia Pública. Cuarenta y ocho (48) pacientes (30 hombres y 18 mujeres) sin antecedentes de: insuficiencia suprarrenal, uso de fenitoína, anticonvulsivantes, rifampicina, ketoconazol, corticosteroides, síndrome de Cushing, patología pituitaria, daño hepático crónico, insuficiencia renal crónica, alcoholismo activo crónico o readmisiones. EL APACHE II fue evaluado al ingreso. Cortisol y DHEA-S fueron medidos a las 00.00 de las primeras 24 h de su ingreso a UTI. Resultados: EL APACHE II (25,1±6,7 contra 16,3±7, p=0,001) y edad (59,5±15,8 contra 44,4±18,1, p 0,011) fueron significativamente más elevados en los fallecidos. En los fallecidos el cortisol mostró una tendencia a niveles más elevados. El DHEA-S mostró niveles considerablemente más altos en los sobrevivientes (5450,9±3824,0 contra 2980,3±2159,3 p= 0,03) junto como el índice DHEA-S/cortisol (12,66±14,19 contra 3,91±4,06, p= 0,004). Conclusiones: La tendencia a niveles más altos de cortisol nocturno observado en las 24 primeras horas induce para pensar que la insuficiencia suprarrenal relativa no desempeñaría un papel en las 24 primeras horas del estado crítico. Los niveles de DHEA-S y el índice DHEA-S/Cortisol son marcadores de sobrevida en nuestra población estudiada.

UNLABELLED: To add data on controversy between the advantages and inconveniences of using either unipolar or bipolar modes for permanent cardiac pacing, we have studied 15 patients. In all of them a CPI Delta-925 (DDD) pulse generator was implanted. Non invasive pacing threshold values in volts were measured at 0.05, 0.08 and 0.1 ms for each chamber programmed either to unipolar or bipolar mode, at 1, 2, 3, 4, 5, 6, 7, 8, 14, 21, 30, 60, 90, 120, 180 and 365 days after the implant. Sensing thresholds were measured at the same time. For any pulse width the mean pacing thresholds in atrium and ventricle increase uniformly, reaching its maximum values between the days 8 and 14 after the implant and decreases to a stable value between 90 and 120 days after the implant, without statistically significant differences for both: unipolar and bipolar modes. Pacing thresholds (V +/- SD) for 0.05 ms in the day 365th were in atrium: unipolar 2.85 +/- 0.79, bipolar 3.35 +/- 0.92 (p = 0.56) and ventricle: unipolar 3.92 +/- 1.01, bipolar 4.36 +/- 1.35 (p = 0.58). Sensing thresholds in atrium and ventricle decreases from the 1st day after the implant with the minimum mean value the day 8th, increasing eventually. No statistically significant differences were found between sensing unipolar/bipolar mode at each chamber. Sensing thresholds (mV +/- SD) in the 365th day were in atrium: unipolar 4.40 +/- 2.07, bipolar 4.10 +/- 2.10 (p = 0.82) and ventricle: unipolar 11.20 +/- 3.63, bipolar 10.10 +/- 5.13 (p = 0.71). CONCLUSIONS: for every single patient: 1) There are not statistically significant differences in the evolution of unipolar and bipolar pacing thresholds both in atrium and ventricle, regarding rate and time of increase, maximum value, rate of decrease and stable chronic values. 2) There are neither statistically significant differences regarding unipolar and bipolar sensing in atrium and ventricle respect to rate of decrease, time and value of the minimum and stable chronic values.

PIP: The study explores the advantages of echography as a diagnostic tool. Echography was used on 100 ginecological patients, of whom 47 had undergone surgery, mostly for tumors. There was a positive correlation between the clinical diagnoses and echography findings, which were corroborated by anatomo-pathological investigations done after surgery. In IUD wearers echography can safely and effectively report on IUD location and/or translocation and consequent pathology. Beside being safe and effective echography is cheap, and helps avoiding unnecessary risks for the patients.^ieng
