Hyperbaric Medicine in Pediatrics — reality of a Portuguese reference center / Medicina Hiperbárica em Pediatria — realidade de um centro de referência português

ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

RESUMO Objetivo: Identificar e caracterizar a população de casos pediátricos encaminhados para o nosso centro de oxigenoterapia hiperbárica. Métodos: Estudo retrospetivo e observacional, que incluiu doentes pediátricos tratados com oxigenoterapia hiperbárica, de 2006 a 2021, no centro de referência de medicina hiperbárica do norte de Portugal. As variáveis de interesse foram extraídas dos processos clínicos eletrônicos. Resultados: O nosso estudo incluiu 134 casos. Os motivos de encaminhamento mais frequentes foram intoxicação por monóxido de carbono (n=59) e surdez súbita neurossensorial (n=41). Em 75 casos (56%) o tratamento foi iniciado em contexto de urgência. Os sintomas de apresentação à admissão variaram entre os diferentes casos, sendo os mais frequentes cefaleias e náuseas/vômitos. No que diz respeito à intoxicação por monóxido de carbono, as fontes mais comuns foram o aquecedor, lareira/braseiro e caldeira. Com relação aos efeitos adversos, foram identificados um caso de intoxicação por oxigênio e quatro casos de barotrauma do ouvido médio. Conclusões: A causa mais frequente de encaminhamento foi a intoxicação por monóxido de carbono. Todos os pacientes evoluíram favoravelmente e foram registrados poucos efeitos adversos, o que enfatiza a segurança desta terapia. Uma vez que a maioria dos pediatras pode não estar informada sobre os potenciais benefícios da oxigenoterapia hiperbárica, é de extrema importância promovê-los para que esta técnica seja cada vez mais implementada.

Acute kidney injury: the experience of a tertiary center of Pediatric Nephrology / Insuficiência renal aguda: experiência de um centro terciário de Nefrologia Pediátrica

ABSTRACT Introduction: Acute kidney injury (AKI) is an abrupt deterioration of kidney function. The incidence of pediatric AKI is increasing worldwide, both in critically and non-critically ill settings. We aimed to characterize the presentation, etiology, evolution, and outcome of AKI in pediatric patients admitted to a tertiary care center. Methods: We performed a retrospective observational single-center study of patients aged 29 days to 17 years and 365 days admitted to our Pediatric Nephrology Unit from January 2012 to December 2021, with the diagnosis of AKI. AKI severity was categorized according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. The outcomes considered were death or sequelae (proteinuria, hypertension, or changes in renal function at 3 to 6 months follow-up assessments). Results: Forty-six patients with a median age of 13.0 (3.5-15.5) years were included. About half of the patients (n = 24, 52.2%) had an identifiable risk factor for the development of AKI. Thirteen patients (28.3%) were anuric, and all of those were categorized as AKI KDIGO stage 3 (p < 0.001). Almost one quarter (n = 10, 21.7%) of patients required renal replacement therapy. Approximately 60% of patients (n = 26) had at least one sequelae, with proteinuria being the most common (n = 15, 38.5%; median (P25-75) urinary protein-to-creatinine ratio 0.30 (0.27-0.44) mg/mg), followed by reduced glomerular filtration rate (GFR) (n = 11, 27.5%; median (P25-75) GFR 75 (62-83) mL/min/1.73 m2). Conclusions: Pediatric AKI is associated with substantial morbidity, with potential for proteinuria development and renal function impairment and a relevant impact on long-term prognosis.

RESUMO Introdução: Insuficiência renal aguda (IRA) é uma deterioração abrupta da função renal. A incidência de IRA pediátrica está aumentando em todo o mundo, em ambientes críticos e não críticos. Nosso objetivo foi caracterizar apresentação, etiologia, evolução e desfechos da IRA em pacientes pediátricos internados em um centro de atendimento terciário. Métodos: Realizamos estudo retrospectivo observacional de centro único de pacientes com idade entre 29 dias a 17 anos e 365 dias internados em nossa Unidade de Nefrologia Pediátrica, de janeiro de 2012 a dezembro de 2021, com diagnóstico de IRA. A gravidade da IRA foi categorizada de acordo com os critérios do Kidney Disease Improving Global Outcomes (KDIGO). Os desfechos considerados foram óbito ou sequelas (proteinúria, hipertensão ou alterações na função renal em avaliações de acompanhamento de 3 a 6 meses). Resultados: Incluímos 46 pacientes com idade mediana de 13,0 (3,5-15,5) anos. Cerca de metade (n = 24; 52,2%) apresentou um fator de risco identificável para o desenvolvimento de IRA. Treze pacientes (28,3%) eram anúricos; todos foram classificados como IRA KDIGO 3 (p < 0,001). Quase um quarto (n = 10; 21,7%) dos pacientes necessitaram de terapia renal substitutiva. Aproximadamente 60% (n = 26) apresentou pelo menos uma sequela, sendo proteinúria a mais comum (n = 15; 38,5%; mediana (P25-75) da relação proteína/creatinina urinária 0,30 (0,27-0,44) mg/mg), seguida de taxa de filtração glomerular (TFG) reduzida (n = 11; 27,5%; mediana (P25-75) da TFG 75 (62-83) mL/min/1,73 m2). Conclusões: A IRA pediátrica está associada à morbidade substancial, com potencial para desenvolvimento de proteinúria e comprometimento da função renal e impacto relevante no prognóstico de longo prazo.

Percutaneous kidney biopsies in children: a 24-year review in a tertiary center in northern Portugal / Biópsias renais percutâneas em crianças: uma revisão de 24 anos em um centro terciário no norte de Portugal

Introduction: Percutaneous kidney biopsy (KB) is crucial to the diagnosis and management of several renal pathologies. National data on native KB in pediatric patients are scarce. We aimed to review the demographic and clinical characteristics and histopathological patterns in children who underwent native percutaneous KB over 24 years. Methods: Retrospective observational study of patients undergoing native percutaneous KB in a pediatric nephrology unit between 1998 and 2021, comparing 3 periods: period 1 (1998-2005), period 2 (2006-2013), and period 3 (2014-2021). Results: We found that 228 KB were performed, 78 (34.2%) in period 1, 91 (39.9%) in period 2, and 59 (25.9%) in period 3. The median age at KB was 11 (7-14) years. The main indications for KB were nephrotic syndrome (NS) (42.9%), hematuria and/or non-nephrotic proteinuria (35.5%), and acute kidney injury (13.2%). Primary glomerulopathies were more frequent (67.1%), particularly minimal change disease (MCD) (25.4%), IgA nephropathy (12.7%), and mesangioproliferative glomerulonephritis (GN) (8.8%). Of the secondary glomerulopathies, lupus nephritis (LN) was the most prevalent (11.8%). In group 1, hematuria and/or non-nephrotic proteinuria were the main reasons for KB, as opposed to NS in groups 2 and 3 (p < 0.01). LN showed an increasing trend (period 1-3: 2.6%-5.3%) and focal segmental glomerular sclerosis (FSGS) showed a slight decreasing trend (period 1-3: 3.1%-1.8%), without statistical significance. Conclusions: The main indication for KB was NS, which increased over time, justifying the finding of MCD as main histological diagnosis. LN showed an increase in incidence over time, while FSGS cases did not increase.

RESUMO Introdução: A biópsia renal (BR) percutânea é fundamental para diagnóstico e manejo de diversas patologias renais. Dados nacionais sobre BR nativa em pacientes pediátricos são escassos. Nosso objetivo foi revisar características demográficas, clínicas e padrões histopatológicos em crianças submetidas a BR percutânea nativa ao longo de 24 anos. Métodos: Estudo observacional retrospectivo de pacientes submetidos a BR percutâneas nativas em unidade de nefrologia pediátrica entre 1998 e 2021, comparando três períodos: período 1 (1998-2005), período 2 (2006-2013), período 3 (2014-2021). Resultados: Constatamos que foram realizadas 228 BR, 78 (34,2%) no período 1, 91 (39,9%) no período 2, 59 (25,9%) no período 3. A idade mediana na BR foi 11 (7-14) anos. As principais indicações para BR foram síndrome nefrótica (SN) (42,9%), hematúria e/ou proteinúria não nefrótica (35,5%), lesão renal aguda (13,2%). Glomerulopatias primárias foram mais frequentes (67,1%), principalmente doença de lesão mínima (DLM) (25,4%), nefropatia por IgA (12,7%), glomerulonefrite mesangioproliferativa (GN) (8,8%). Das glomerulopatias secundárias, nefrite lúpica (NL) foi a mais prevalente (11,8%). No grupo 1, hematúria e/ou a proteinúria não nefrótica foram os principais motivos para BR, ao contrário da SN nos grupos 2 e 3 (p < 0,01). A NL apresentou tendência crescente (período 1-3: 2,6%-5,3%) e a glomeruloesclerose segmentar focal (GESF) apresentou leve tendência decrescente (período 1-3: 3,1%-1,8%), sem significância estatística. Conclusões: A principal indicação para BR foi SN, que aumentou ao longo do tempo, justificando o achado de DLM como principal diagnóstico histológico. A NL apresentou aumento na incidência ao longo do tempo, enquanto os casos de GESF não aumentaram.

El tumor inflamatorio de Pott: una complicación infrecuente de la sinusitis. Reporte de caso / Pott's puffy tumor: A rare complication of sinusitis. A case report

Una complicación infrecuente de la sinusitis frontal es el tumor inflamatorio de Pott. Se manifiesta como una tumefacción en la frente por la presencia de un absceso subperióstico secundario a una osteomielitis del hueso frontal. El diagnóstico oportuno permite un tratamiento intensivo médico y quirúrgico precoz, esencial para evitar complicaciones intracraneales graves. Se presenta el caso de un varón de 12 años con un tumor inflamatorio de Pott como complicación de una pansinusitis. Representó un desafío diagnóstico; sin embargo, la instauración del tratamiento oportuno permitió una evolución clínica favorable.

A rare complication of frontal sinusitis includes Pott's puffy tumor. It manifests as a swelling of the forehead due to the presence of a subperiosteal abscess secondary to osteomyelitis of the frontal bone. A timely diagnosis allows for an early, intensive medical and surgical treatment, which is critical to prevent serious intracranial complications. Here we describe the case of a 12-year-old boy with Pott's puffy tumor as a complication of pansinusitis. This case was a diagnostic challenge; however, a timely treatment allowed for a favorable clinical course.

Síndrome de la costilla deslizante en la edad pediátrica. Serie de casos / Slipping rib syndrome in childhood. A case series

Entre las causas de dolor torácico, la costilla deslizante presenta baja prevalencia, antecedentes traumáticos y manejo controvertido. Este síndrome merece ser incluido en el diagnóstico diferencial de causas de dolor torácico en niños. Al no asociarse a traumatismos previos y la deformidad de cartílagos, nos induce a pensar en una alteración en el desarrollo costal, al margen de la etiología traumática típica en adultos. Se presenta una serie de pacientes pediátricos intervenidos por costilla deslizante en un centro de referencia entre 2001 y 2022. Se incluyeron nueve pacientes, con un rango de edades de 11 a 16 años. Solo dos casos describen traumatismo previo. Todos presentan un inicio súbito de dolor toracoabdominal intenso. Los pacientes fueron intervenidos mediante resección abierta de cartílagos costales afectos, con resolución del dolor.

Among the causes of chest pain, slipping rib has a low prevalence, usually with a history of trauma, and its management is controversial. Slipping rib syndrome should be included in the differential diagnosis of causes of chest pain in children. When not associated with previous trauma and cartilage deformity, it is necessary to consider an alteration in rib development, regardless of the typical traumatic etiology in adults. Here we describe a series of pediatric patients with slipping rib seen at a referral hospital between 2001 and 2022. Nine patients aged 11 to 16 years were included. Only 2 had a history of trauma. All patients described a sudden onset of severe thoracic abdominal pain. The patients underwent open resection of the affected costal cartilages, with resolution of pain.

Tumores del sistema nervioso central. Clasificación de la Organización Mundial de la Salud 2021. Hacia un cambio de paradigma / Tumors of the central nervous system. Classification of the World Health Organization 2021. Towards a paradigm shift

El estudio de los tumores del sistema nervioso central (SNC) resulta ser un tema de gran consideración y su conocimiento reviste una alta importancia en la práctica médica. Las clasificaciones de las neoplasias del SNC comenzaron a mediados del siglo XIX hasta que en 1979 la Organización Mundial de la Salud (OMS) publicó la primera edición de una sistemática útil con el objetivo de establecer un lenguaje común para todas las especialidades médicas. Al día de hoy, 5 ediciones actualizaron la taxonomía neoplásica. La quinta edición del año 2021 consolida el cambio de paradigma dado por los avances moleculares, si bien todavía la transición se encuentra en proceso entre la caracterización morfológica y la biológica molecular. En este artículo, se analizan las nuevas modificaciones incorporadas en las diferentes familias tumorales más frecuentes en pediatría haciendo hincapié en aquella información de utilidad para el médico pediatra en su práctica diaria y la consulta multidisciplinaria.

The study of central nervous system (CNS) tumors is a subject of great interest and such knowledge is of great importance in medical practice. The classifications of CNS neoplasms began in the mid-19 th century, until the World Health Organization (WHO) published, in 1979, the first edition of a useful systematic review for the purpose of establishing a common language for all medical specialties. To date, 5 updated editions of neoplastic taxonomy have been published.The fifth edition, from 2021, consolidates the paradigm shift brought about by molecular advances, although the transition between morphological and molecular biological characterization is still in progress. In this article, the new modifications introduced in the different most frequent families of tumors in pediatrics are analyzed, emphasizing useful information for pediatricians in their daily practice and multidisciplinary consultations.

Pericardiectomía parcial y drenaje pericárdico mínimamente invasivo en cirugía infantil / Partial pericardiectomy and minimally invasive pericardial drainage in pediatric surgery

Introducción. Una de las patologías más frecuentes del pericardio es la pericarditis, que puede presentarse como pericarditis aguda, subaguda o crónica, derrame pericárdico, taponamiento cardíaco o pericarditis constrictiva. Sin embargo, es una condición infrecuente en la población pediátrica. Métodos. Presentamos una serie de casos de pacientes con pericarditis que fueron llevados a pericardiotomía, drenaje pericárdico y pericardiectomía parcial anterior, entre julio de 2014 y junio de 2023. Se recolectaron las variables demográficas y clínicas, se evaluaron los aislamientos microbiológicos y el manejo recibido. Resultados. Un total de 12 pacientes fueron llevados a manejo quirúrgico mínimamente invasivo; de estos, 58 % pertenecían a comunidades indígenas y residían en zonas rurales. La mitad tenían neumonía asociada. En la mayoría de los casos no se obtuvo aislamiento microbiológico. Conclusión. La necesidad de manejo quirúrgico está determinada por la repercusión en las variables hemodinámicas relacionadas con el derrame y el compromiso pericárdico. La pericardiectomía parcial por toracoscopia es una alternativa en estos casos.

Introduction. One of the most common pathologies of the pericardium is pericarditis, which can present as acute, subacute or chronic pericarditis, pericardial effusion, cardiac tamponade or constrictive pericarditis. However, it is a rare condition in the pediatric population. Methods. A series of cases of patients with pericarditis who were taken to pericardiotomy, pericardial drainage and anterior partial pericardiectomy, between July 2014 and June 2023 is presented. Demographic and clinical variables were collected, microbiological isolates and the management received were evaluated. Results. A total of 12 patients underwent minimally invasive surgical management; of these, 58% belonged to indigenous communities and lived in rural areas. Half had associated pneumonia. In most cases, no microbiological isolation was obtained. Conclusion. The need for surgical management is determined by the impact on the hemodynamic variables related to the effusion and pericardial compromise. Partial pericardiectomy by thoracoscopy is an alternative in these cases.

Shock séptico: complicación atípica de duplicación del tracto alimentario / Septic shock: an atypical complication of alimentary tract duplication

Las duplicaciones del tracto alimentario son un conjunto heterogéneo de anomalías congénitas del tubo digestivo. Su forma de presentación es variada, y pueden desarrollar distintas complicaciones libradas a su evolución natural. La infección es una complicación poco frecuente, pero que no puede desconocerse por la gravedad que implica. Se presenta el caso de una paciente de 2 años de edad, previamente sana, con una complicación atípica de una duplicación del tracto alimentario: un shock séptico. Consultó inicialmente por distensión y dolor abdominal asociado a una masa abdominal palpable. Los estudios imagenológicos evidenciaron una formación líquida parcialmente tabicada en el hemiabdomen derecho. Durante la internación, se presentó una infección intratumoral, que evolucionó al shock séptico. Respondió favorablemente al tratamiento médico del shock, y se realizó la exéresis quirúrgica posteriormente. La anatomía patológica confirmó la duplicación del tracto alimentario.

Alimentary tract duplications are heterogenous congenital anomalies of the digestive tract. Their form of presentation is varied, and they may lead to different complications, depending on their natural course. Infection is a rare complication, but it cannot be ignored because of its severity. Here we describe the case of an otherwise healthy 2-year-old girl with an atypical complication of alimentary tract duplication: septic shock. She initially consulted due to abdominal distension and pain associated with a palpable abdominal mass. The imaging studies showed a partial fluid septation in the right side of the abdomen. During hospitalization, an intratumoral infection developed, which progressed to septic shock. The patient responded favorably to medical treatment for shock, and surgical resection was subsequently performed. The pathology report confirmed the presence of alimentary tract duplication.

Percepción de competencia bioética y deliberación ético-clínica conjunta medicina-enfermería en hospitalización pediátrica básica

Introducción: las competencias bioéticas permiten abordar colectiva y críticamente, aspectos éticos involucrados en la práctica clínica. Pero, la deliberación ética simultánea de médico/as con enfermero/as, en pacientes no críticos, es inhabitual. Objetivo: constatar la percepción de médico/as y enfermero/as de un hospital de alta complejidad, sobre sus competencias bioéticas y deliberación sincrónica, en hospitalizados pediátricos sin riesgo vital. Métodos: se realizó un estudio descriptivo y transversal mediante encuesta, a médico/as y enfermero/as del servicio médico-quirúrgico infantil, sobre presencia, modalidad de enseñanza de bioética en pregrado, percepción de tener conocimiento bioético suficiente para aplicarlo clínicamente y si hubo análisis ético-clínico conjunto, en pacientes hospitalizados. Resultados: la mayoría de los encuestados 47/54 (87%) recibió formación teórica obligatoria en bioética durante el pregrado. De ellos, 19/29 (65,5%) médico/as y 11/18 (61,1%) enfermero/as reconocieron que esta formación fue insuficiente para aplicarla en el trabajo. 25/35 (71,4%) médicos, afirmó participar en deliberación ética antes de enviar un caso al comité de ética asistencial, pero esta deliberación ocasionalmente incluyó a enfermero/as ya que, sólo 2/19 (10,5%) de los enfermero/as señalaron intervenir en este tipo de deliberación. Conclusiones: médico/as y enfermero/as que trabajan en pediatría y cirugía infantil, perciben insuficiencias de formación en pregrado en bioética e impericia para aplicar contenidos a la práctica cotidiana. La deliberación ética sobre casos clínicos pediátricos de enfermero/as es esporádica respecto de médico/as en hospitalización médico-quirúrgica básica.

Introduction: Bioethical skills are essential for addressing, both collectively and critically, ethical issues that arise in clinical practice. However, joint ethical deliberation between physicians and nurses with non-critical patients is uncommon Objective: To study the perception of physicians and nurses regarding their bioethical skills in a high-complexity hospital and whether they engage in collective deliberation in units of pediatric inpatients not at vital risk. Methods: A descriptive, cross-sectional study was conducted via a survey targeting physicians and nurses in the pediatric medical-surgical service. The survey inquired about the presence and modality of bioethics teaching during undergraduate education, the perception of having sufficient bioethical knowledge for clinical application, and whether joint ethical-clinical analysis was performed regarding hospitalized patients. Results: Most respondents, 47/54 (87%), had received mandatory theoretical training in bioethics during their undergraduate education. 19/29 (65.5%) physicians and 11/18 (61.1%) nurses acknowledged that this training was insufficient for application in their work. A high percentage of physicians, 19/29 (65.5%), claimed to carry out ethical analysis of cases before referring them to the healthcare ethics committee, occasionally including nurses since only 2/18 (11.1%) of the nurses indicated participation in such analysis. Conclusions: Medical and nursing professionals who work in pediatrics and children's surgery perceive insufficiencies in undergraduate training in bioethics issues and an inability to apply content to daily practice. Ethical deliberation on pediatric clinical cases by nurses is sporadic compared to doctors in basic medical-surgical hospitalization.

Falta de adherencia al control médico en pacientes pediátricos con antecedente de glomerulonefritis infecciosa

Introducción: La glomerulonefritis pos infecciosa (GNPI) en la infancia es un factor de riesgo para el desarrollo de enfermedad renal crónica a largo plazo. La adherencia al control médico permite realizar la nefroprevención secundaria. Objetivo: evaluar la relación entre los factores de riesgo relacionados a la falta de adherencia al control médico de pacientes con GNPI en una cohorte pediátrica. Metodología: estudio descriptivo de asociación cruzada de cohorte retrospectiva de pacientes internados entre enero de 2000 a diciembre de 2018 en un hospital de referencia. Se analizó la relación entre: hacinamiento, colecho, escolaridad materna y paterna, número de hermanos, de convivientes y procedencia, con la falta de adherencia al control médico. Se utilizaron la prueba de chi cuadrado y regresión logística a un nivel de significancia de 0,05. Resultados: Se incluyeron 148 pacientes (103 niños y 45 niñas) entre 2 a 16 años (edad promedio: 8,5± 3,4 años). La falta de adherencia fue encontrada en 73 pacientes (49,3%) que se asoció a procedencia rural (p= 0,012, RR: 1,50, IC95%: 1,10-2,06), baja escolaridad materna (p= 0,046, IC95%: 1,54:1,14-2,08), baja escolaridad paterna (p= 0,02; RR: 1,483, IC95%: 1,09-2,01), >3 convivientes (p=0,007, RR: 1,630, IC95%: 1,21-2,19), colecho (p=0,026; RR: 1,52, IC95%: 1,02-2,27) y hacinamiento (p<0,0001; RR: 1,92, IC95%: 1,39-2,65). Por regresión logística, el hacinamiento (p=0,005; OR= 4,8) y procedencia rural (p=0,022; OR: 2,4) se mantuvieron asociados a la falta de adherencia. Discusión: El hacinamiento y la procedencia rural se asociaron en forma independiente con la pérdida de seguimiento. Se recomienda mayor intervención de la atención primaria de salud.

Introduction: Post-infectious glomerulonephritis (PIGN) in childhood is a risk factor for the development of long-term chronic kidney disease. Adherence to medical control allows secondary nephroprevention to be carried out. Objective: to evaluate the relationship between risk factors related to non-adherence to medical control of patients with IPGN in a pediatric cohort. Methods: descriptive study, with an analytical component of a retrospective cohort of patients hospitalized between January 2000 and December 2018 in a reference hospital. The relationship between: overcrowding, co-sleeping, maternal and paternal education, number of siblings, cohabitants and origin, with lack of adherence to medical control was analyzed. The chi-square test and logistic regression were used at a significance level of 0.05. Results: a total of 148 patients (103 boys y 45 girls) between 2 and 16 years old (mean age: 8.5± 3.4 years) were included. The lack of adherence was found in 73 patients (49.3%) that was associated with rural origin (p= 0.012, RR: 1.50, 95% CI: 1.10-2.06), low maternal education (p= 0.046, 95%CI: 1.54:1.14-2.08), low paternal education (p= 0.02; RR: 1.483, 95%CI: 1.09-2.01), >3 cohabitants (p=0.007, RR: 1.630, 95% CI: 1.21-2.19), co-sleeping (p=0.026; RR: 1.52, 95% CI: 1.02-2.27) and overcrowding (p<0.0001; RR: 1.92, 95% CI: 1.39-2.65). By logistic regression, overcrowding (p=0.005; OR= 4.8) and rural origin (p=0.022; OR: 2.4) remained associated with lack of adherence. Discussion: Overcrowding and rural origin were independently associated with loss to follow-up. Greater intervention by primary health care is recommended.

Seguimiento de niños con diagnóstico de asma grave antes y durante la pandemia por COVID-19 / Follow-up of children diagnosed with severe asthma before and during the COVID-19 pandemic

En la pandemia por COVID-19 se exploraron estrategias de atención para garantizar el seguimiento de niños con asma grave. Estudio prospectivo, observacional, comparativo. Se incluyeron pacientes del programa de asma grave de un hospital pediátrico de tercer nivel (n 74). Se evaluó el grado de control, exacerbaciones y hospitalizaciones durante un período presencial (PP), marzo 2019-2020, y uno virtual (PV), abril 2020-2021. En el PP, se incluyeron 74 pacientes vs. 68 (92 %) del PV. En el PP, el 68 % (46) de los pacientes presentaron exacerbaciones vs. el 46 % (31) de los pacientes en el PV (p 0,003). En el PP, se registraron 135 exacerbaciones totales vs. 79 en el PV (p 0,001); hubo una reducción del 41 %. En el PP, el 47 % (32) de los pacientes tuvieron exacerbaciones graves vs. el 32 % (22) de los pacientes en el PV (p 0,048). Hubo 91 exacerbaciones graves en el PP vs. 49 en el PV (p 0,029), reducción del 46 %. No hubo diferencias en las hospitalizaciones (PP 10, PV 6; p 0,9). La telemedicina fue efectiva para el seguimiento de pacientes con asma grave

During the COVID-19 pandemic, health care strategies were explored to ensure the follow-up of children with severe asthma. This was a prospective, observational, and comparative study. Patients in the severe asthma program of a tertiary care children's hospital were included (n: 74). The extent of control, exacerbations, and hospitalizations during an in-person period (IPP) (March 2019­2020) and an online period (OP) (April 2020­2021) was assessed. A total of 74 patients were enrolled in the IPP compared to 68 (92%) in the OP. During the IPP, 68% (46) of patients had exacerbations versus 46% (31) during the OP (p = 0.003). During the IPP, 135 total exacerbations were recorded compared to 79 during the OP (p = 0.001); this accounted for a 41% reduction. During the IPP, 47% (32) of patients had severe exacerbations versus 32% (22) during the OP (p = 0.048). A total of 91 severe exacerbations were recorded during the IPP compared to 49 during the OP (p = 0.029); the reduction was 46%. No differences were observed in terms of hospitalization (IPP: 10, OP: 6; p = 0,9). Telemedicine was effective for the follow-up of patients with severe asthma.

Tuberculosis abdominal en pediatría: presentación de un caso / Abdominal tuberculosis in pediatrics: A case report

La tuberculosis es una enfermedad infectocontagiosa cuya forma de presentación más frecuente es la pulmonar; la afectación abdominal es poco frecuente, por lo que su diagnóstico continúa siendo un desafío. Las manifestaciones clínicas de la tuberculosis abdominal así como sus hallazgos en el examen físico suelen ser inespecíficos y, en muchas ocasiones, similares a los de otras patologías, por lo que es fundamental considerarla entre los diagnósticos diferenciales. Se presenta el caso clínico de un paciente de sexo masculino, de 15 años de edad, hospitalizado por un síndrome febril prolongado asociado a dolor abdominal, diarrea, sudoración nocturna y pérdida de peso

Tuberculosis is an infectious disease which most commonly compromises the respiratory system, whereas abdominal involvement is rare, thus its diagnosis is a challenge. The clinical manifestations of abdominal tuberculosis as well as its physical examination findings are usually non-specific and, frequently, similar to those of other diseases, so it is critical to consider abdominal tuberculosis among the differential diagnoses. Here we report the clinical case of a 15-year-old male patient hospitalized for a prolonged febrile syndrome associated with abdominal pain, diarrhea, night sweats, and weight loss.

Feocromocitoma y paraganglioma en un hospital pediátrico de Argentina. Serie de casos / Pheochromocytoma and paraganglioma at a children's hospital in Argentina. A case series

El feocromocitoma y el paraganglioma son tumores neuroendocrinos secretores de catecolaminas. Los feocromocitomas se originan en la médula suprarrenal, mientras que los paragangliomas son extraadrenales. Se describe una serie de casos de niños con diagnóstico anatomopatológico de feocromocitoma o paraganglioma que consultaron en un hospital pediátrico de alta complejidad de Argentina. Se incluyeron 21 pacientes, 14 varones, con una mediana de edad de 11,4 años; 8 casos con feocromocitoma y 13 casos con paraganglioma. Se presentaron con hipertensión arterial 14/21. La mayoría de los paragangliomas tuvieron localización paraaórtica (9/13). Debido a que representan una causa potencialmente curable de hipertensión arterial, la sospecha clínica es muy importante. El diagnóstico temprano y la instauración de un tratamiento antihipertensivo adecuado, que permita afrontar la cirugía con normotensión arterial, aseguran la curación en la mayoría de los casos si la resección tumoral es completa.

Pheochromocytomas and paragangliomas are neuroendocrine tumors producing catecholamines. Pheochromocytomas occur in the adrenal medulla, while paragangliomas are those that occur outside the adrenal gland. Here we describe a case series of children with a pathological diagnosis of pheochromocytoma or paraganglioma who consulted at a tertiary care children's hospital in Argentina. A total of 21 patients (14 males) were included; their median age was 11.4 years; 8 children had pheochromocytoma and 13, paraganglioma. Arterial hypertension was observed in 14/21. Most paragangliomas were para-aortic (9/13). Since they are a potentially curable cause of hypertension, clinical suspicion is very important. An early diagnosis and the initiation of an adequate antihypertensive treatment, which allows the patient to undergo surgery with normal blood pressure, ensure a cure in most cases if tumor resection is complete.

Validez de herramientas diagnósticas en pacientes pediátricos hospitalizados con diagnóstico presuntivo de dengue en un Hospital de Referencia de Paraguay / Validity of diagnostic tools in pediatric patients hospitalized with a presumptive diagnosis of dengue in a Reference Hospital in Paraguay

Introducción: El dengue es la enfermedad arboviral más común en los seres humanos. Un diagnóstico temprano y preciso del dengue puede respaldar el manejo clínico, la vigilancia y el control de la enfermedad y es fundamental, por ello en el diagnóstico del dengue es importante contar con pautas clínicas y epidemiológicas que permitan la identificación oportuna y una conducta terapéutica adecuada. Objetivos: Evaluar la validez de herramientas diagnósticas en pacientes pediátricos hospitalizados con diagnóstico presuntivo de dengue en un Hospital de Referencia de Paraguay durante los años de 2012 a 2020. Materiales y métodos: Estudio analítico de tipo observacional, retrospectivo correspondientes a pacientes pediátricos (0 a 18 años) internados en el Hospital de Referencia de Paraguay el periodo enero 2012 a julio 2020 con diagnostico presuntivo de dengue al ingreso. Se realizó́ un análisis bivariado relacionando las frecuencias de 20 grupos de criterios diagnósticos combinados y 3 criterios diagnósticos aislados (OMS 2009, nexo epidemiológico y antigenemia NS1 para dengue) con el gold standard de diagnóstico que fue la conversión serológica. Resultados: Participaron del estudio 342 sujetos. EL 44% tenía edad escolar y 70% tenía 5 años o más. El 52,76% (191) fueron masculinos. Se encontraron desnutrición y sobrepeso en el 13% y 2%, respectivamente. La combinación de proteína C reactiva con plaquetopenia se encontró́ en 0.45% de los pacientes sin dengue y en el 6% de los pacientes con diagnóstico final de dengue (p=0.004). Conclusión: Este resultado aporta la alternativa de uso de una combinación sencilla de exámenes de laboratorio que puede replicarse en salas de urgencias como en salas de internación en un primer contacto con pacientes febriles con sospecha de fiebre dengue.

Introduction: Dengue is the most common arboviral disease in humans. An early and accurate diagnosis of dengue can support the clinical management, surveillance and control of the disease and is essential, therefore in the diagnosis of dengue it is important to have clinical and epidemiological guidelines that allow timely identification and appropriate therapeutic conduct. Objectives: To evaluate the validity of diagnostic tools in pediatric patients hospitalized with a presumptive diagnosis of dengue in a Reference Hospital in Paraguay during the years 2012 to 2020. Materials and methods: Analytical study of case and control type, observational, longitudinal, retrospective corresponding to pediatric patients (0 to 18 years) admitted to the Reference Hospital of Paraguay from January 2012 to July 2020 with a presumptive diagnosis of dengue at income. A bivariate analysis was performed relating the frequencies of 20 groups of combined diagnostic criteria and 3 isolated diagnostic criteria (WHO 2009, epidemiological link and NS1 antigenemia for dengue) with the gold standard of diagnosis, which was serological conversion. Results: 342 subjects participated in the study. 44% were school age and 70% were 5 years old or older. 52.76% (191) were male. Malnutrition and overweight were found in 13% and 2%, respectively. The combination of C-reactive protein with thrombocytopenia was found in 0.45% of patients without dengue and in 6% of patients with a final diagnosis of dengue (p=0.004). Conclusion: This result provides the alternative of using a simple combination of laboratory tests that can be replicated in emergency rooms and inpatient wards in a first contact with febrile patients with suspected dengue fever.

La marihuana de hoy no es la que fumaba tú abuela

Johnny Stack, como nos lo relata Isabella Backman, se inició en la marihuana en una fiesta de la escuela a sus 14 años, cuando apenas se había legalizado su uso medicinal en Colorado. Esa marihuana la había obtenido el hermano mayor de unos de sus amigos, quien tenía una tarjeta para marihuana medicinal. A los 19 años, después de 5 años de estar luchando contra adicción y psicosis, Johnny muere por suicidio. Tres días antes, nos dice Backman, le dijo a su madre que la marihuana le había arruinado su mente y su vida. Nunca se probó, a pesar de múltiples pruebas de laboratorio, que usara ninguna otra droga. (provisto por Infomedic International)

Johnny Stack, as Isabella Backman tells us, was introduced to marijuana at a school party when he was 14 years old, when its medical use had just been legalized in Colorado. That marijuana had been obtained by the older brother of one of her friends, who had a medical marijuana card. At 19, after five years of struggling with addiction and psychosis, Johnny died by suicide. Three days earlier, Backman tells us, he told his mother that marijuana had ruined his mind and his life. It was never proven, despite multiple lab tests, that he used any other drug. (provided by Infomedic International)
