ABSTRACT

Introdución: La ingesta accidental de cáusticos en pediatría no dispone de un consenso claro de actuación. El objetivo de este estudio fue caracterizar la población pediátrica atendida por ingesta de cáusticos en un centro asistencial. Pacientes y método: Estudio descriptivo de los pacientes atendidos en nuestro hospital por la ingesta de cáusticos durante el período 2008-2011. Resultados: Se atendieron 12 pacientes, edad media de 3,8 años (1-13 años). Predominio de varones (58,8%). Un 58,3% ingirió producto alcalino y un 41,6% ácido. El 58,3% no refería sintomatología, el resto refirió vómitos (33,3%), odinofagia (16,6%), hematemesis (8,3%), sialorrea (8,3%) y dificultad respiratoria (8,3%). El 75% presentaron lesiones en la cavidad oral. Todos, salvo un caso, fueron accidentales. Se realizó endoscopia al 100% entre las 12 y 24 h postingesta con hallazgos patológicos en un 41,6%. En el grupo ingesta de álcalis 2 pacientes presentaron lesiones (16,6%): una esofagitis grado 2B y una grado 3. En el grupo ingesta de ácidos 4 pacientes (33,3%) presentaron lesiones: una esofagitis aguda grado 1-2A, 2 gastritis agudas no erosivas y una gastritis aguda hemorrágica. Se realizó endoscopia de control según los hallazgos endoscópicos previos. Solo 2 presentaron complicaciones posteriores. Conclusiones: Destacamos la valoración endoscópica en las primeras 24 h en todas las ingestas sintomáticas y deliberadas, así como la reevaluación estrecha en las ingestas ácidas, por asociar lesiones diferidas.


Introduction: There is no clear consensus on the management of accidental ingestion of caustic substances in paediatrics. The aim of this study was to determine the profile of the paediatric population treated due to caustic ingestion in a Healthcare Centre. Patients and method: A descriptive study was conducted on patients treated for the ingestion of caustic substances in our hospital during the period 2008-2011. Results: A total of 12 patients were treated, with a mean age of 3.8 years (1-13 years), with the majority males (58.8%). An alkaline product was ingested by 58.3%, and an acid by 41.6%. The majority (58.3%) did not refer to symptoms and the remainder referred to vomiting (33.3%), odynophagia (16.6%), haematemesis (8.3%), hyper-salivation (8.3%) and shortness of breath (8.3%). Oral cavity lesions were observed in 75% of cases. All, except one, were accidental. An endoscopy was performed on all of them (100%) between 12 and 24 hours post-ingestion, with pathological findings in 41.6%. In the group that ingested an alkali, 2 (16.6%) patients had lesions, one a grade 2B and one a grade 3 oesophagitis. In the acid ingestion group, 4 (33.3%) patients had lesions; one grade 1-2A oesophagitis, two acute non-erosive gastritis, and one acute haemorrhagic gastritis. A follow-up endoscopy was performed depending on the previous endoscopic findings. Only two patients presented with complications. Conclusions: Emphasis is placed on the endoscopic evaluation in the first 24 hours of deliberate asymptomatic ingestions, as well as a strict follow-up in those that ingested acids, due to delayed associated lesions.

ABSTRACT

INTRODUÇÃO: O presente estudo abordou a questão da hospitalização de 13 pacientes, crianças e adolescentes, enfocando especificamente o paciente queimado internado em um Centro de Tratamento de Queimaduras. O objetivo foi o de observar e analisar a percepção dos envolvidos no processo de tratamento, para compreender a relação desse paciente com a dor, com o processo de tratamento, com a qualidade de vida no ambiente hospitalar e com sua autoimagem. Levantar informações que revelem a importância de um trabalho profilático do trauma térmico. MÉTODO: Para atender os objetivos da pesquisa, foi utilizado o método de investigação de Estudo de Caso com abordagem qualitativa. RESULTADOS: Os resultados apontaram uma maioria dos pacientes do sexo masculino. O agente etiológico predominante foi o etanol. Os acidentes causaram queimaduras de gravidades diversas, sendo 1 de 1º e 2º graus, 7 de 2º e 3º graus e 5 de 3º grau. O tempo de internação variou de 15 a 75 dias. As idades dos pacientes variaram entre 1 ano e oito meses a 18 anos. Quanto à escolarização, com exceção do paciente mais novo, todos frequentavam a rede de ensino. Quanto ao nível socioeconômico, a maioria tem uma renda familiar de até dois salários mínimos, que não são suficientes. De modo geral, encontra-se apenas uma pessoa trabalhando, por família. CONCLUSÕES: Os resultados pesquisados demonstram a necessidade de orientação aos pais, com programas educativos e campanhas de prevenção.


INTRODUCTION: The present study addressed the issue of hospitalization in 13 patients, children and adolescents, specifically focusing on burn patients admitted to a center for burn treatment. The objective of this study was to observe and analyze the perception of those involved in the treatment process in order to understand the relationship of the patient with pain and the treatment process with the quality of life in the hospital environment and with their self-image, and to collect information on the importance of prophylactic treatment on thermal trauma. METHODS: To meet the objectives of the research, we used the case study method with a qualitative approach. RESULTS: The results showed that most of the patients were male. The predominant etiologic agent was ethanol. The accidents caused burns of various severities, first- and second-degree burns in 1 patient, second- and third-degree burns in 7 patients, and third-degree burns in 5 patients. The length of hospitalization ranged from 15 to 75 days. The ages of the patients ranged from 1 year 8 months to 18 years. As to education, with the exception of the youngest patient, all attended the school network. Regarding socioeconomic level, most had a family income of up to 2 minimum wages, which was not sufficient. In general, only one person worked per family. CONCLUSIONS: The results demonstrate the need to provide guidance to parents, with educational programs and campaigns.

ABSTRACT

The Korean list of occupational skin diseases was amended in July 2013. The past list was constructed according to the causative agent and the target organ, and the items of that list had not been reviewed for a long period. The revised list was reconstructed to include diseases classified by the International Classification of Diseases (10th version). Therefore, the items of compensable occupational skin diseases in the amended list in Korea comprise contact dermatitis; chemical burns; Stevens-Johnson syndrome; tar-related skin diseases; infectious skin diseases; skin injury-induced cellulitis; and skin conditions resulting from physical factors such as heat, cold, sun exposure, and ionized radiation. This list will be more practical and convenient for physicians and workers because it follows a disease-based approach. The revised list is in accordance with the International Labor Organization list and is refined according to Korean worker's compensation and the actual occurrence of occupational skin diseases. However, this revised list does not perfectly reflect the actual status of skin diseases because of the few cases of occupational skin diseases, incomplete statistics of skin diseases, and insufficient scientific evidence. Thus, the list of occupational diseases should be modified periodically on the basis of recent evidence and statistics.

ABSTRACT

OBJETIVOS: Avaliar a ação do bevacizumabe subconjuntival em modelo experimental de neovascularização em córnea de coelho. Analisar se o modelo de avaliação empregado é adequado e comparar entre os grupos a extensão dos vasos, inflamação e re-epitelização da córnea. MÉTODOS: Estudo experimental, prospectivo em 20 coelhos submetidos a trauma químico com hidróxido de sódio a 1 N divididos em dois grupos, Imediatamente após a queimadura, o grupo tratado recebeu injeção subconjuntival de 0,15 ml (3,75 mg) de bevacizumabe e o grupo controle, injeção subconjuntival de 0,15 ml de soro fisiológico a 0,9 por cento. Após 25 dias, foi realizada análise fotográfica digital para avaliar a extensão e inflamação/calibre dos vasos segundo critério pré-estabelecido e estudo histopatológico da córnea, no qual foi avaliado o estado do epitélio e o número de polimorfonucleares. RESULTADOS: A extensão dos neovasos corneanos foi menor no grupo estudo em relação ao controle (p<0,001). Não houve diferença significativa entre os grupos na inflamação/calibre dos vasos. A análise histopatológica mostrou que não ocorreu diferença entre os grupos nas variáveis estado do epitélio e número de polimorfonucleares. A análise de concordância para a variável extensão dos vasos e para a variável inflamação/calibre dos vasos teve uma estimativa do coeficiente de Kappa respectivamente de 0,705 e 0,500 indicando bom grau de concordância nas diferentes avaliações cegadas, validando o método empregado. CONCLUSÕES: O modelo de avaliação foi adequado e pode ser reproduzido para avaliar outras drogas na córnea. O bevacizumabe inibiu a neovascularização corneana, porém não foi eficaz em reduzir o processo inflamatório. A droga não atrasou a re-epitelização da córnea.


PURPOSES: To evaluate the effect of subconjunctival bevacizumab in an experimental model of neovascularization in rabbit cornea. Determine its effect on vessels extension, inflammation, epithelialization of the cornea and whether the evaluation method used is appropriate to compare neovascular models. METHODS: Experimental, prospective, randomized, blinded study in twenty rabbits subjected to chemical trauma with sodium hydroxide at 1N divided into two groups. The study group received subconjunctival injection of 0.15 ml (3.75 mg) of bevacizumab and was compared with the control group that received subconjunctival injection of 0.15 ml saline solution. After 25 days, digital photographic analysis was performed to assess the vessel's extension and inflammation/diameter according to pre-established criteria. Histopathology of the cornea, which evaluated the state of the epithelium and the number of polymorphonuclear cells was also studied. RESULTS: The length of the neovessels was greater in the control group compared to the study group (P=<0.001). There was no difference in inflammation/vessel diameter between groups. Histopathology analysis showed that there was no difference between groups for the variables state of the epithelium and number of polymorphonuclear cells. The concordance analysis for the variable extension of the vessels and the variable inflammation/vessel diameter was estimated with Kappa coefficients of 0.705 and 0.500 respectively, indicating a good level of agreement in different evaluations and validating the method. CONCLUSIONS: The experimental model is adequate and can be reproduced to evaluate other drugs in the cornea. Bevacizumab inhibit the neovessels' growth but was not effective in preventing the inflammatory response. The drug did not delay the reepithelialization of the cornea.

ABSTRACT

The ingestion of caustic substances is an important emergency situation, because of its serious consequences. PURPOSE: To study morphological and functional alterations of the esophagus in rabbits submitted to esophageal infusion of caustic soda (NaOH). METHODS: The 88 rabbits studied were divided into 4 groups: G1 (n=22) were submitted to esophageal infusion with distilled water. G2, G3, and G4 were submitted to esophageal infusion of 2 percent, 4 percent and 6 percent NaOH respectively. Morphological alterations were studied in 12 animals from each group and manometric alterations in the remaining 10. An analysis was made of lower esophageal sphincter (LES) pressure, number and amplitude of contractions in the distal third of the esophagus. These studies were performed before (moment M1) and at 30 minutes, 6 hours, and 24 hours after (moments M2, M3, and M4, respectively) esophageal infusion. RESULTS: Morphological evaluation: G1 - no alterations; G2 - edema, hyperemia, and ecdysis; G3 - enlarged calibre of esophagus, ulcers, ecdysis of mucosa; G4 - lesions similar to G3, but more intense, areas of extensive hemorrhage at M3 and M4. Functional evaluation: LES was higher at M2; the number of distal third lower esophageal contractions in G3, and G4 was lower; and the contraction amplitude was lower in G4. CONCLUSIONS: 1) Esophageal infusion with caustic soda in rabbits is a good experimental model for studying caustic esophagites. 2) Esophageal infusion with NaOH caused lesions in the esophageal wall, with gravity proportional to solution concentration; 3) Infusion caused LES spasm at M2, and reduced both contraction number and amplitude in the distal third of the esophagus.


A ingestão de substâncias cáusticas constitui importante situação de emergência, tendo em vista a gravidade de suas seqüelas. OBJETIVO: Estudar as alterações morfológicas e funcionais do esôfago de coelhos submetidos à infusão esofágica com soda cáustica (NaOH). MÉTODOS: 88 coelhos foram divididos em 4 grupos: G1 (n=22) foi submetido à infusão esofágica com água destilada; G2, G3 e G4 foram submetidos a infusão esofágica com NaOH a 2 por cento, 4 por cento e 6 por cento, respectivamente. Alterações morfológicas foram estudadas em 12 animais de cada grupo e as alterações manométricas, nos 10 animais restantes. Foram feitas análises do esfíncter inferior do esôfago (EIE), número e amplitude das contrações no terço distal do esôfago. Estes estudos foram realizados antes (momento 1 - M1) e aos 30 minutos, 6 horas e 24 horas após a infusão esofágica (momentos M2, M3 e M4, respectivamente). RESULTADOS: Avaliação macroscópica: G1 - sem alterações; G2 - edema, hiperemia e descamação; G3 - aumento do calibre do esôfago, úlceras, descamação da mucosa; G4 - lesões semelhantes as do G3, porém mais intensas, áreas de extensa hemorragia. Avaliação funcional: a pressão no EIE foi mais elevada em M2 no grupo 2; o número das contrações no terço distal do esôfago foi menor em G3 e G4, e a amplitude das contrações foi menor em G4. CONCLUSÕES: 1) a infusão esofágica com NaOH constitui excelente modelo experimental de esofagite cáustica no coelho; 2) a infusão esofágica com NaOH causa lesões na parede do esôfago, com gravidade proporcional a concentração da solução; 3) a infusão causou espasmo do EIE em M2 e redução do número e amplitude das contrações no terço distal do esôfago.

ABSTRACT

This experiment shows the effect of milk and albumin of eggs on caustic burns of the oesophagus without any medical or surgical interference to avoid masking of the effect of milk and albumin on caustic burns. Twenty four [24] rabbits were included in this work, divided into 4 major groups: one control three treated. They are further subdivided into twelve [12] subgroups depending on survival time and type of treatment [milk only, egg only or milk and egg]. The ingestion of milk and/or egg albumin diminished the local inflammatory reactions and granulations in they were given immediately after caustic ingestion. All control animals living over 3 weeks had stricture formation. No stricture was found in treated groups. The best results were found in the treated groups with milk and egg albumin together. So it is advisable to give a mixture of milk and egg albumin immediately to any child suspected to have ingested caustic material

ABSTRACT

Este trabajo tiene como líneas generales la presentación y discusión de las características principales de la evolución de las lesiones térmicas, esencialmente de los aspectos relacionados al sistema cardiovascular. Así, la formación de edema y la evaporación de agua son comentadas, no olvidando, sin embargo, que estas dependen de alteraciones en la permeabilidad vascular o en la capa córnea de la piel, respectivamente. El choque, determinado por la excesiva reducción del volumen de plasma sanguíneo, es la etapa crítica alcanzada por el paciente quemado

ABSTRACT

Se presenta una paciente de edad pediátrica, con lesiones de quemaduras químicas debido a compuestos fenólicos concentrados, y repercusión sistémica. La histopatología mostró necrosis de coagulación. Se destaca la acción de los compuestos fenólicos en la piel, de acuerdo a su concentración. Las quemaduras ocurren como accidentes, la mayor parte de ellas laborales. Actualmente, la presencia de fenol industrial concentrado en los hogares permite que puedan ocurrir casos de intoxicación accidental, como en nuestra paciente. Creemos que difundirse el conocimiento de estos cuadros, debido a la creciente utilización de estos compuestos, que engrosarían el espectro de tóxicos caseros que pueden provocar accidentes

ABSTRACT

Se revisaron 48 pacientes con diagnóstico de quemadura esofágica por cáuticos. De éstos, 21 fueron hombres y 27 mujeres. La causa principal fue accidente en lactantes y preescolares, suicidio en adolescentes femeninas y accidentes bajo efecto del alcohol en hombres adultos. El agente principal la sosa cáustica. La estenosis fue la complicación principal que requirió dilatación en 40 pacientes con resultados buenos sólo en la tercera parte de los casos. Se realizaron l3 trasposiciones de colon: seis con colon derecho, y seis con colon izquierdo y con un transverso. La evolución fue buena en seis pacientes con trasposición izquierda; buena en cinco pacientes con trasposición derecha; sin embargo, ocurrieron una muerte y una estenosis. El único paciente en que se realizó transposición transversa desarrolló estenosis .
