RESUMEN

ABSTRACT Objective: The aim of this study was to describe the epidemiological characteristics of pediatric patients with sickle cell disease (SCD) and evaluate the use of medicinal plants in these patients concomitantly with their drug treatment. Methods: This is a review of the medical records of pediatric patients at a public institution with tertiary care. The selection criterion was to be a child or adolescent with SCD undergoing pediatric follow-up at this outpatient clinic. In the medical records of the patients selected, records of the use of plants for medicinal purposes were sought. Results: In total, 154 records (100% of total active patients followed in this clinic) were reviewed: 99 children and 55 adolescents. The predominant genotype was SS (58.4%), followed by SC (29.2%). The use of at least one medication for SCD was reported in 95.5% of the medical records. The use of medicinal plants was reported by 70.1% of patients, with 276 citations in the medical records referring to 64 different types of plants. Six plants were used for the treatment of SCD, the main one being Lemonvine/Ora-pro-nóbis (Pereskia aculeata). The use of medicinal plants was reported for flu-like symptoms and/or COVID-19 (both for prevention and treatment) by 60.5% of the citations, with 35 different plants reported for this use, exclusively or not. This use was followed by pain symptoms (14.2% of citations). Conclusions: The majority of patients in this study use both conventional and traditional/complementary/alternative medicine, highlighting the need for more studies in the area, with a special focus on patient safety.

RESUMO Objetivo: Descrever as características epidemiológicas de pacientes pediátricos com doença falciforme (DF) e avaliar o uso de plantas medicinais concomitantemente ao tratamento medicamentoso. Métodos: Realizou-se revisão de prontuários de pacientes pediátricos de uma instituição pública com nível de atendimento terciário; o critério de seleção foi ser criança ou adolescente com DF em acompanhamento pediátrico neste ambulatório. Nos prontuários dos pacientes selecionados foi procurado o registro do uso de plantas com finalidades medicinais. Resultados: Foram revisados 154 prontuários (100% dos pacientes ativos desse ambulatório): 99 crianças e 55 adolescentes. O genótipo predominante foi SS (58,4%), seguido do SC (29,2%). O uso de ao menos uma medicação para a DF foi relatada em 95,5% dos prontuários. Em 70,1% dos prontuários havia o relato do uso de plantas medicinais, em 276 citações, sendo 64 plantas citadas ao todo; destas, seis espécies foram citadas para o tratamento da doença de base (DF), sendo "ora-pro-nobis" (Pereskia aculeata) a principal. Das 276 citações de plantas medicinais nos prontuários, 60,5% incluíram o uso de plantas medicinais em sintomas gripais e/ou COVID-19 (tanto prevenção quanto tratamento), sendo relatadas 35 para este uso, exclusivamente ou não. Essa foi a principal finalidade de uso encontrada nos prontuários dos pacientes, seguida do uso para sintomas de dor (14,2% das citações). Conclusões: Notou-se que a maioria dos pacientes avaliados faz uso da medicina convencional, aliada à tradicional/ complementar/ alternativa, o que leva à necessidade de mais estudos nessas áreas, especialmente na pediatria, visando principalmente à segurança do paciente.

RESUMEN

ABSTRACT Objective: The aim of this study was to describe the phases of a decannulation protocol and the results from its application in hospitalized children. Methods: This is a retrospective, observational study. Data were collected from medical records of decannulated patients followed up in a pediatric hospital in Belo Horizonte, Minas Gerais between 2011 and 2021. Results: Among the children followed up in the service (n=526), 23% (n=120) were successfully decannulated. Children aged between 2 months and 16 years, with a mean age of 4 years, 69% of whom were male, were evaluated. About 75% of the patients have tracheostomy due to upper airway obstruction and 60% of these due to acquired subglottic stenosis. At the beginning of the decannulation protocol, 5.5% of the patients had moderate oropharyngeal dysphagia, while 80.4% had normal swallowing. Correction in the upper airway pre-decannulation was performed in 39.5% of the patients, dilation in 63.8%, and endoscopic correction was performed in 55.3%. After performing the decannulation, none of the patients had complications. Conclusions: The described decannulation protocol is safe, since no complications such as death and need for recannulation happened.

RESUMO Objetivo: Descrever as etapas de um protocolo de decanulação e os resultados da aplicação desse protocolo em crianças hospitalizadas. Métodos: Trata-se de um estudo observacional retrospectivo. Os dados foram coletados de prontuários de pacientes decanulados acompanhados em um hospital pediátrico de Belo Horizonte, Minas Gerais, entre 2011 e 2021. Resultados: Foram analisadas 120 crianças com idade entre dois meses e 16 anos, com média de idade de quatro anos, 69% das quais eram do sexo masculino. Cerca de 75% dos pacientes apresentam traqueostomia por obstrução de vias aéreas superiores e 60% destes por estenose subglótica adquirida. No início do protocolo de decanulação, 5,5% dos pacientes apresentavam disfagia orofaríngea moderada, enquanto 80,4% apresentavam deglutição normal. A correção da pré-decanulação das vias aéreas superiores foi realizada em 39,5% dos pacientes, a dilatação em 63,8% e a correção endoscópica em 55,3%. Após a realização da decanulação, nenhum paciente apresentou complicações. Conclusões: O protocolo de decanulação descrito é seguro, pois a taxa de complicações como óbito e a necessidade de recanulação foi ausente.

RESUMEN

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.

RESUMEN

Cryptosporidium spp. es un protozoario productor de diarrea. Los pacientes inmunocomprometidos pueden desarrollar formas clínicas graves y persistentes. Se describen las características de pacientes con enfermedad de base asociada a inmunosupresión (EAI) con infección por Cryptosporidium spp. (IC) atendidos en un hospital pediátrico referencial de Argentina entre los años 2018 y 2023. Se analizaron datos demográficos, EAI, características de la diarrea y coinfecciones. Se incluyeron 30 pacientes con EAI e IC. La mayoría registró trasplante de órgano sólido, neoplasia hematológica e inmunodeficiencia primaria. Dieciocho presentaron diarrea persistente al momento del diagnóstico. Seis pacientes registraron coinfecciones. Se debe considerar la criptosporidiosis en el diagnóstico diferencial de enfermedad diarreica aguda o persistente en niños con distintos tipos de EAI, como el trasplante de órgano sólido, neoplasias hematológicas e inmunodeficiencias primarias.

Cryptosporidium spp. is a diarrhea-causing protozoan. Immunocompromised patients may develop severe and persistent clinical forms. Here we describe the characteristics of patients with an underlying disease associated with immunosuppression (DAI) and Cryptosporidium spp. infection seen at a referral children's hospital in Argentina between 2018 and 2023. Demographic data, DAI, diarrhea characteristics, and co-infections were analyzed. A total of 30 patients with DAI and cryptosporidiosis were included. Most of them had undergone a solid organ transplant, had a hematologic neoplasm, or primary immunodeficiency. Persistent diarrhea was observed in 18 patients at the time of diagnosis. Co-infections were recorded in 6 patients. Cryptosporidiosis should be considered in the differential diagnosis of acute or persistent diarrhea in children with different types of DAI, such as solid organ transplant, hematologic neoplasms, and primary immunodeficiencies.

RESUMEN

La agenesia de la vesícula biliar es una entidad rara en pediatría con una evolución normalmente silente, y representa un desafío diagnóstico para el médico que enfrenta estos casos por primera vez. Algunos pacientes pueden, sin embargo, presentar síntomas que simulan otras patologías del árbol biliar, y muchos de ellos son operados ante esta sospecha. Sin embargo, el diagnóstico oportuno de esta entidad permite llevar a cabo un tratamiento médico que muchas veces es suficiente para resolver el problema del paciente. Si bien es una condición benigna, los pacientes suelen presentar otras malformaciones asociadas que son más graves en naturaleza y que deben investigarse activamente para poder derivarlos a los especialistas de manera oportuna. Presentamos nuestra experiencia en el diagnóstico y tratamiento de estos pacientes, así como una breve revisión de la literatura. Esperamos que sea de utilidad para el médico que encuentre un caso similar.

Gallbladder agenesis is a rare condition in pediatrics that is usually asymptomatic and represents a diagnostic challenge for physicians seeing these cases for the first time. Some patients may, however, present with symptoms that mimic other diseases of the bile ducts, and many of them undergo surgery due to such suspicion. Still, a timely diagnosis of gallbladder agenesis allows for medical treatment that is often sufficient to resolve the patient's problem. Although it is a benign condition, patients often present with other associated, more serious malformations and should be actively studied for a timely referral to other specialists. Here we describe our experience with the diagnosis and treatment of these patients and a brief review of the bibliography. We hope it will be helpful for physicians facing similar cases.

RESUMEN

La linfohistiocitosis hemofagocítica (LHH) es una entidad rara que se caracteriza por un estado hiperinflamatorio secundario a la activación desregulada del sistema inmune con compromiso multisistémico. Puede ser primaria o hereditaria, o estar desencadenada por diversas enfermedades. La mortalidad sin tratamiento oportuno es del 50 % de los casos. Se presenta el caso de una paciente de 1 año y 8 meses con diagnóstico reciente de infección por virus de inmunodeficiencia humana en estadio sida. Cursó internación para estudio e inicio de tratamiento antirretroviral durante la cual presentó múltiples intercurrencias infectológicas e inmunológicas. Se destacan dos episodios de linfohistiocitosis hemofagocítica en contexto de inmunodeficiencia adquirida no controlada y coinfecciones oportunistas. El objetivo de este reporte es destacar la importancia de la sospecha de LHH para un diagnóstico y tratamiento pertinente

Hemophagocytic lymphohistiocytosis (HLH) is a rare condition characterized by a hyperinflammatory state secondary to dysregulated immune activity with multisystem involvement. HLH may be primary or hereditary, or triggered by various diseases. Mortality without a timely treatment reaches 50% of the cases. Here we describe the case of a 1-year and 8-month-old female patient with a recent diagnosis of human immunodeficiency virus infection in the AIDS stage. She was hospitalized for assessment and initiation of antiretroviral therapy during which she developed multiple intercurrent infectious and immune conditions. Two episodes of hemophagocytic lymphohistiocytosis in the setting of uncontrolled acquired immunodeficiency and opportunistic co-infections stand out. The objective of this case report is to highlight the importance of suspecting HLH for a relevant diagnosis and treatment.

RESUMEN

El escorbuto es una enfermedad producida por déficit de vitamina C. Aunque es poco frecuente, en los últimos años observamos un incremento de casos en niños con trastornos de la conducta alimentaria. Sus manifestaciones son variadas, ya que esta vitamina actúa como cofactor en numerosos procesos, como la síntesis de colágeno. Las manifestaciones cutáneas características son las petequias, equimosis e hiperqueratosis. El compromiso mucoso se manifiesta como gingivitis con hipertrofia, hemorragias y pérdida de piezas dentarias. El diagnóstico es clínico y puede confirmarse mediante la determinación de la vitamina C plasmática. El objetivo de este trabajo es describir una cohorte de pacientes diagnosticados en los últimos años, manifestaciones clínicas y hallazgos en relación con su conducta alimentaria y trastornos del neurodesarrollo.

Scurvy is a disease caused by vitamin C deficiency. Although rare, in recent years, the number of scurvy cases in children with eating disorders has increased. Its manifestations are varied because vitamin C is a cofactor in numerous processes, such as collagen synthesis. The typical skin manifestations include petechiae, bruising, and hyperkeratosis. Mucosal involvement manifests as gingivitis with hypertrophy, bleeding, and loss of teeth. The diagnosis is based on clinical findings and may be confirmed by measuring plasma vitamin C levels. The objective of this study was to describe a cohort of patients diagnosed with scurvy in recent years, its clinical manifestations, and findings in relation to their eating behavior and neurodevelopmental disorders.

RESUMEN

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.

RESUMEN

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.

RESUMEN

Abstract Surgery is a key pillar in medical care, and both the surgical as well as the anesthetic components are essential within the health systems in countries of all levels of development. Every year, close to 230 million surgical procedures are performed worldwide, with pediatric surgery being representative, as around 85% of children require a surgical procedure. However, the issue of education and training of the people involved in pediatric surgery who can provide safe surgical and anesthetic care in medium and low income countries has been absent from the global health debate. The development of anesthesia in pediatrics faces many challenges: it is a relatively new specialty, it has to deal with clinical challenges associated with anatomical, physiological, psychological and procedure-related differences, while it faces the reality of few training opportunities which results in a limited number of duly trained and qualified specialists in pediatric anesthesiology. In Latin America, the possibility of applying to a specialization in pediatric anesthesia is limited. In particular in Colombia it has not been possible to establish a pediatric anesthesia subspecialty, creating the need to promote formal and informal training in this discipline in order to ensure that safe, good quality anesthetic care is provided to children. This article describes the development of pediatric anesthesia training in the world and in Colombia, highlighting the relationship between the incidence of anesthetic complications and the need for training in this discipline.

Resumen La cirugía es una parte indispensable en la atención médica, siendo el componente quirúrgico y el anestésico fundamentales dentro del sistema de salud en países de todos los niveles de desarrollo. Anualmente, se realizan alrededor de 230 millones de procedimientos quirúrgicos en todo el mundo, siendo la cirugía pediátrica un porcentaje, ya que alrededor del 85 % de los niños requiere un procedimiento quirúrgico; sin embargo, la prestación de servicios quirúrgicos y anestésicos seguros desde la formación y entrenamiento de los actores involucrados en la atención quirúrgica infantil en países de medianos y bajos ingresos ha estado ausente del discurso de salud global. El desarrollo del campo de la anestesia en pediatría enfrenta múltiples retos: es una especialidad relativamente nueva, presenta desafíos clínicos relacionados con las diferencias anatómicas, fisiológicas, psicológicas y procedimentales, así como existen pocas oportunidades de entrenamiento con el consecuente número limitado de especialistas en anestesiología pediátrica capacitados y calificados. Para América latina, las posibilidades de aplicar a una especialización en anestesiología pediátrica son limitadas y específicamente para Colombia no ha sido posible crear la subespecialidad de anestesiología pediátrica, por lo que se debe fomentar la formación formal e informal en esta disciplina, con el fin de ofrecer una atención anestésica segura y con calidad para los niños. Este artículo hace un recuento del desarrollo de la formación en anestesiología pediátrica en el mundo y en Colombia, visibilizando la relación con la incidencia de complicaciones anestésicas y la necesidad de formación en esta disciplina.

RESUMEN

La tomografía por impedancia eléctrica (TIE) es una modalidad de monitorización funcional respiratoria por imagen, no invasiva y libre de radiación, que permite visualizar en tiempo real la ventilación pulmonar regional y global en pacientes adultos y pediátricos conectados a Ventilación Mecánica (VM). OBJETIVO: Se describe la utilidad de la TIE en dos pacientes críticos pediátricos, en quienes no fue factible realizar medición de mecánica pulmonar, como herramienta para el ajuste de parámetros ventilatorios. CASOS CLÍNICOS: Se presentan dos pacientes pediátricos de 27 y 11 meses con condiciones clínicas diferentes, conectados a VM, en quienes se utilizó la TIE como método de monitoreo de la distribución pulmonar y titulación de la presión positiva al final de la espiración (PEEP) óptima, con el objetivo de obtener una ventilación pulmonar más homogénea. Se presentan mediciones funcionales con diferentes niveles de PEEP y valores de distribución en las distintas regiones de interés (ROI), además de un flujograma de situaciones en las que la TIE podría resultar útil para el ajuste ventilatorio. CONCLUSIÓN: La información funcional proporcionada por la TIE, permitió monitorizar de forma dinámica la VM y optimizar los parámetros ventilatorios, facilitando la implementación de estrategias de protección pulmonar en ambos pacientes, imposibilitados de realizar una medición estática de la mecánica respiratoria.

The Electrical Impedance Tomography (EIT) is a non-invasive and radiation-free respiratory functional imaging monitoring modality that allows real-time visualization of regional and global lung ventilation in adult and pediatric patients connected to mechanical ventilation (MV). OBJECTIVE: This paper describes the utility of EIT in two critical pediatric patients for whom measuring pulmonary mechanics was not feasible. EIT is used as a tool for adjusting ventilatory parameters. CLINICAL CASES: Two pediatric patients aged 27 and 11 months, with different clinical conditions, connected to MV are presented. EIT was used to monitor lung distribution and titrate the optimal Positive End-Expiratory Pressure (PEEP), to achieve more homogeneous lung ventilation. Functional measurements are presented with different PEEP levels and distribution values in different regions of interest (ROI), along with a flowchart illustrating situations where EIT could be useful for ventilatory adjustment. CONCLUSION: The functional information provided by EIT, allowed dynamic monitoring of MV, optimizing ventilatory parameters and facilitating the implementation of lung protective strategies in both patients, unable to undergo static respiratory mechanics measurements.

RESUMEN

Introdução: Queimaduras são lesões teciduais causadas pelo contato com fontes de calor. Representam um problema de saúde pública global. Em crianças causam grandes impactos. A gravidade e intensidade das queimaduras estão relacionadas ao agente etiológico e suas consequências são um grande obstáculo para o paciente. Método: O estudo analisou dados de internações hospitalares por queimaduras em crianças de 2012 a 2022, utilizando informações do SIH-SUS. Foram calculadas taxas de internações por 100.000 habitantes para cada ano, considerando variáveis dependentes. Os pesquisadores utilizaram coeficientes padronizados e regressão linear simples para analisar os dados. Resultados: Incluíram-se dados de 91.091 internações por queimaduras em crianças, 0-14 anos. Verificou-se estabilidade na taxa geral de internações (taxa média 17,963; ß=0,119; p=0,163). No sexo feminino houve tendência de aumento (taxa média 14,346; ß=0,169; p=0,029); no masculino de estabilidade (taxa média 21,426; ß=0,069; p=0,504). O sexo feminino comportou-se com estabilidade em todas as faixas etárias; o masculino com aumento na faixa 0-4 anos (taxa média 42,264; ß=0,613; p=0,003), estabilidade na faixa 5-9 anos (taxa média 14,189; ß=-0,21; p=0,867) e redução na faixa 10-14 anos (taxa média 9,871; ß= -0,328; p=0,007). A Região Sul demonstrou tendência de aumento (taxa média 26,952; ß=1,091; p=0,001). Conclusão: Houve estabilidade na taxa geral de internações. O sexo feminino tendeu ao aumento e o masculino à estabilidade. Houve estabilidade nas regiões brasileiras, exceto no Sul.

Introduction: Burns are tissue injuries caused by contact with heat sources. They represent a global public health problem. They have major impacts on children. The severity and intensity of burns are related to the etiological agent and their consequences are a major obstacle for the patient. Method: The study analyzed data on hospital admissions for burns in children from 2012 to 2022, using information from SIH-SUS. Hospitalization rates per 100,000 inhabitants were calculated for each year, considering dependent variables. The researchers used standardized coefficients and simple linear regression to analyze the data. Results: Data from 91,091 hospitalizations for burns in children, 0-14 years old, were included. There was stability in the general hospitalization rate (mean rate 17.963; ß=0.119; p=0.163). In females there was an increasing trend (mean rate 14.346; ß=0.169; p=0.029); in males, there was stability (mean rate 21.426; ß=0.069; p=0.504). Females behaved with stability in all age groups; the male with an increase in the range 0-4 years (mean rate 42.264; ß=0.613; p=0.003), stability in the range 5-9 years (mean rate 14.189; ß=-0.21; p=0.867) and reduction in the range 10-14 years (mean rate 9.871; ß= -0.328; p=0.007). The South Region demonstrated an increasing trend (mean rate 26.952; ß=1.091; p=0.001). Conclusion: There was stability in the general hospitalization rate. The female sex tended towards increase and the male towards stability. There was stability in Brazilian regions, except in the South.

Objetivo: refletir sobre os cuidados paliativos em oncopediatria, desenvolvido por enfermeiros, a partir do referencial teórico proposto por Jean Watson. Método: estudo teórico-reflexivo, realizado em agosto de 2023, durante a elaboração de Tese de Doutorado, embasado em publicações científicas nacionais e internacionais sobre a Teoria do Cuidado Humano de Jean Watson e sobre cuidados paliativos em oncopediatria. Resultados: observou-se que a presente teoria pode subsidiar o enfermeiro a superar a filosofia do cuidado direcionado apenas as necessidades físicas, visto que os principais conceitos da teoria despertam reflexões relevantes sobre as dimensões biopsicossocioespirituais da criança com câncer em assistência paliativa. Considerações finais: a abordagem holística contribui com a promoção do bem-estar e da qualidade de vida, independente do prognóstico da doença. A utilização dos 10 elementos do Processo Caritas, favorece a assistência efetivada por meio de um processo dinâmico, permeado pelo carinho, atenção, respeito, lúdico e comunicação efetiva.

Objective: to reflect on palliative care in pediatric oncology, developed by nurses, based on the theoretical framework proposed by Jean Watson. Method: theoretical-reflective study, carried out in August 2023, during the preparation of the Doctoral Thesis, based on national and international scientific publications on Jean Watson's Theory of Human Care and on palliative care in pediatric oncology. Results: it was observed that the present theory can support nurses to overcome the philosophy of care directed only to physical needs, since the main concepts of the theory awaken relevant reflections on the biopsychosocial-spiritual dimensions of children with cancer undergoing palliative care. Final considerations: the holistic approach contributes to promoting well-being and quality of life, regardless of the prognosis of the disease. The use of the 10 elements of the Caritas Process favors assistance provided through a dynamic process, permeated by affection, attention, respect, fun and effective communication.

RESUMEN

BACKGROUND: Vascular malformations (VaMs) are caused by errors in vascular morphogenesis. Diagnosis and treatment can be complex. Few specialized centers care for these patients, and limited literature exists regarding their characteristics and clinical course. The vascular anomalies clinic (VAC) at the Instituto Nacional de Pediatría (National Institute for Pediatrics) is a multidisciplinary team and has been a reference center for patients with VaMs since 2012. We sought to describe the characteristics of patients cared for at the VAC, types of VaMs, treatments used, and clinical course. METHODS: This was a descriptive, observational, retrospective, and cross-sectional study conducted from 2012 to 2022. RESULTS: We included 435 patients with VaMs; the median age of presentation was 1 month. The most frequent signs and symptoms were increased volume (97.2%), superficial color change (65.5%), and pain (43.3%). The most common VaMs were lymphatic (36.7%) and venolymphatic (18.3%). Sclerotherapy was the most frequent treatment (73.4%), followed by medical treatment with sirolimus (18.5%); response to both was excellent/good in > 85% of cases. CONCLUSION: In this retrospective study of children with VaMs, we found that low-flow malformations were the most common, and sclerotherapy and sirolimus were the most frequently used treatments. The therapeutic response was excellent/good in most cases.

INTRODUCCIÓN: Las malformaciones vasculares (MaV) son secundarias a errores en la morfogénesis vascular. El diagnóstico y tratamiento puede ser complejo. Existen pocos centros especializados en su atención y escasa literatura respecto a características y evolución clínica. La Clínica de Anomalías Vasculares (CAV) del Instituto Nacional de Pediatría es un equipo multidisciplinario y centro de referencia para estos pacientes desde 2012. Buscamos describir las características de los pacientes atendidos en la CAV, tipo de MaV, tratamiento y evolución clínica. MÉTODOS: Estudio descriptivo, observacional, retrospectivo y transversal del periodo 2012 al 2022. RESULTADOS: Se incluyeron 435 pacientes con MaV, con edad mediana de presentación de 1 mes de vida. Los síntomas y signos más reportados fueron aumento de volumen (97.2%), cambio en coloración de la piel (65.5%) y dolor (43.3%). Las MaV más comunes fueron linfáticas (36.7%), siguiéndoles las venolinfáticas (18.3%). La escleroterapia fue el tratamiento más frecuente (73.4%) y el tratamiento médico más utilizado fue sirolimus (18.5%), ambos con excelente/buena respuesta en > 85% de los pacientes. CONCLUSIONES: En este estudio retrospectivo de niños con MaV encontramos que las más frecuentes son de bajo flujo y el tratamiento más usado escleroterapia y sirolimus. La respuesta terapéutica de la mayoría fue excelente/buena.

RESUMEN

Introducción: Entre 0,3-0,5% de niños nacidos presentan una vena cava superior izquierda persistente, lo que lo hace una de las malformaciones congénitas más frecuentes del drenaje venoso. El drenaje de esta en la aurícula derecha, además del drenaje de la vena cava superior derecha en la aurícula izquierda, es extremadamente infrecuente. Caso Clínico: Se presenta el caso de un infante de 8 meses asintomático que es llevado a consulta por presentar desaturaciones. El examen físico es normal. El ecocardiograma de contraste con solución salina muestra una vena cava superior izquierda persistente que drena en la aurícula derecha y un retorno anómalo de la vena cava superior derecha. Se realiza una corrección quirúrgica y evoluciona de forma favorable. Conclusión: La presentación en simultáneo de una vena cava superior izquierda persistente que drena en la aurícula derecha y una vena cava derecha que drena en la aurícula izquierda es extremadamente rara. La mayoría de los casos registrados se diagnosticaron de manera incidental en personas adultas al no presentar síntomas.

Introduction: Between 0.3-0.5% of children born have a persistent left superior vena cava, which makes it one of the most frequent congenital malformations of venous drainage. Drainage of this vein into the right atrium, in addition to drainage of the right superior vena cava into the left atrium, is extremely rare. Clinical case: We present a case of an asymptomatic 8-month-old infant who was taken to the clinic for desaturations. Physical examination was normal. The contrast echocardiogram with saline solution showed a persistent left superior vena cava draining into the right atrium and an anomalous return of the right superior vena cava. Surgical correction was performed and the patient evolved favorably. Conclusion: The simultaneous presentation of a persistent left superior vena cava draining into the right atrium and a right superior vena cava draining into the left atrium is extremely rare. Most of the reported cases were diagnosed incidentally in adults in the absence of symptoms.

RESUMEN

Introducción: El carcinoma de células escamosas de cabeza y cuello, es una malignidad rara en la población pediátrica. Su incidencia ha ido en aumento en las últimas décadas y los principales factores de riesgo descritos son inmunosupresión y transmisión vertical del virus del papiloma humano (VPH). Presentación del caso: presentamos a un paciente masculino de 14 años con historia de 2 años de disfonía intermitente que luego progreso a estridor laríngeo por lo cual se le realizo traqueostomía con micro laringoscopia directa, donde se evidenció una lesión de aspecto verrucoso y bordes irregulares comprometiendo hemilaringe derecha y paralizándola. Se le toma biopsia y se reporta carcinoma de células escamosas moderadamente invasor (p16 positivo). Luego de evaluación multidisciplinaria, tratándose de una enfermedad localmente avanzada, se decide tratamiento con quimio radioterapia definitiva con intención de preservación orgánica. Conclusión: debido a lo poco común del cáncer de laringe en la población pediátrica y la poca evidencia que hay en cuanto a opciones de tratamiento, limita nuestro conocimiento de esta patología solo a reporte de casos y revisiones de la literatura. consideramos necesario realizar este reporte de caso para agregar información sobre esta patología poco común (provisto por Infomedic International)

Introduction: Squamous cell carcinoma of the head and neck is a rare malignancy in the pediatric population. Its incidence has been increasing in the last decades and the main risk factors described are immunosuppression and vertical transmission of human papillomavirus (HPV). Case presentation: we present a 14-year-old male patient with a 2-year history of intermittent dysphonia that later progressed to laryngeal stridor, for which he underwent tracheostomy with direct micro laryngoscopy, where a lesion of verrucous aspect and irregular borders was evidenced, compromising the right hemilaringeal region and paralyzing it. A biopsy was taken and a moderately invasive squamous cell carcinoma (p16 positive) was reported. After multidisciplinary evaluation, being a locally advanced disease, it was decided to treat with definitive chemo-radiotherapy with the intention of organ preservation. Conclusion: due to the rarity of laryngeal cancer in the pediatric population and the lack of evidence regarding treatment options, our knowledge of this pathology is limited to case reports and literature reviews. We consider it necessary to make this case report to add information on this uncommon pathology. (provided by Infomedic International)

RESUMEN

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.
