RESUMO
Objective: To investigate the role of an inflammatory microenvironment induced by Porphyromonasgingivalis (P. gingivalis) in the occurrence of esophageal squamous cell carcinoma (ESCC) in mice. Methods: A total of 180 C57BL/6 mice were randomly divided into 6 groups, i.e. control group, P. gingivalis group, 4NQO group, 4NQO + P. gingivalis group, 4NQO + P. gingivalis + celecoxib group, and 4NQO + P. gingivalis + antibiotic cocktail (ABC, including metronidazole, neomycin, ampicillin, and vancomycin) group, with 30 mice in each group, using the random number table. All mice were normalized by treatment with ABC in drinking water for 2 weeks. In the following 2 weeks, the mice in the control group and the P. gingivalis group were given drinking water, while the other 4 groups were treated with 30 µg/ml 4NQO in the drinking water. In weeks 11-12, the mice in the P. gingivalis group, the 4NQO + P. gingivalis group, the 4NQO + P. gingivalis + celecoxib group, and the 4NQO + P. gingivalis + ABC group were subjected to ligation of the second molar in oral cavity followed by oral P. gingivalis infection thrice weekly for 24 weeks in weeks 11-34. In weeks 13-34, the mice in 4NQO + P. gingivalis+celecoxib group and 4NQO + P. gingivalis + ABC group were administered with celecoxib and ABC for 22 weeks, respectively. At the end of 34 weeks, gross and microscopic alterations were examined followed by RT-qPCR and immunohistochemistry to examine the expression profiles of inflammatory- and tumor-molecules in esophagi of mice. Results: At 34 weeks, 4NQO treatment alone did not affect the foci of papillary hyperproliferation, diseased area, and the thickness of the esophageal wall, but significantly enhanced the foci of hyperproliferation (median 1.00, Pï¼0.05) and mild/moderate dysplasia (median 2.00, Pï¼0.01). In addition, the expression levels of IL-6 [8.35(3.45,8.99)], IL-1ß [6.90(2.01,9.72)], TNF-α [12.04(3.31,14.08)], c-myc [2.21(1.80,3.04)], pSTAT3, Ki-67, and pH2AX were higher than those in the control group. The pathological changes of the esophageal mucosa were significantly more overt in the 4NQO + P. gingivalis group in terms of the foci of papillary hyperproliferation (median 2.00), diseased area (median 2.51 mm2), the thickness of the esophageal wall (median 172.52 µm), the foci of hyperproliferation (median 1.00, Pï¼0.05), and mild/moderate dysplasia (median 1.00, Pï¼0.01). In mice of the 4NQO + P. gingivalis group, the expression levels of IL-6 [12.27(5.35,22.08)], IL-1ß [13.89(10.04,15.96)], TNF-α [19.56(6.07,20.36)], IFN-γ [11.37(8.23,20.07)], c-myc [2.62(1.51,4.25)], cyclin D1 [4.52(2.68,7.83)], nuclear pSTAT3, COX-2, Ki-67, and pH2AX were significantly increased compared with the mice in the control group. In mice of the 4NQO + P. gingivalis group, the diseased area, invasive malignant foci as well as pSTAT3 and pH2AX expression were significantly blunted by celecoxib. Treatment with ABC markedly reduced the papillary hyperproliferative foci, invasive malignant foci, and pSTAT3 expression but not pH2AX. Conclusions: P. gingivalis promotes the occurrence of esophageal squamous cell carcinoma in mice by inducing an inflammatory microenvironment primed with 4NQO induced DNA damage. Clearance of P. gingivalis with ABC or anti-inflammatory intervention holds promise for prevention of esophageal squamous cell malignant pathogenesis via blockage of IL-6/STAT3 signaling and amelioration of inflammation.

PURPOSE: We aimed to examine the effectiveness of mother milk exosomes in treating corrosive esophageal burns. MATERIALS AND METHODS: 32 rats were separated into four equal groups and weighed individually before the procedure. A corrosive esophageal burn model was created with 12.5% sodium hydroxide by a 3F Fogarty catheter. Group 1 did not apply any process or treatment, Group 2 was burned, and no treatment was performed. Group 3 was burned, and then 0.5 cc/day of mother milk exosome extract was given. Group 4 was not applied any process, and 0.5 cc/day mother milk exosome extract was given. All rats were weighed again and sacrificed. Biopsy samples were sent to the pathology laboratory for histopathological examination (in terms of inflammation, fibrosis, and necrosis).Kindly check and confrm all email ids.The e-mail addresses and affiliation of all authors were checked. Affiliation departments are as stated on the title page. There is no change. RESULTS: A significant difference was found in the results of inflammation and fibrosis. There was a meaningful difference in fibrosis between the 2nd and 3rd groups. There was weight gain in groups 1, 3 and 4. Statistical evaluations for each group were significant. CONCLUSION: It was observed that breast milk exosomes may be effective in inflammation and fibrosis formation in treating corrosive esophageal burns. This suggested that breast milk exosomes reduce stricture formation due to esophageal corrosion.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name).

Esophagitis dissecans superficialis (EDS) is a rare disease characterized by sloughing of the superficial esophageal mucosa and, histologically, by the bitonal appearance of the squamous epithelium secondary to necrosis of the most superficial layers. Etiology is uncertain, however, it has been associated with some medications, autoimmune diseases, esophageal stasis and endoscopic procedures. Here, two cases are presented, one of them which appeared in a woman after an episode of dysphagia and another one which occurred to a man with comorbidities and epigastric pain. This entity should be considered due to its self-limiting clinical course, compared to other entities with a more torpid evolution or that require more specific treatment.

Acute necrotizing esophagitis (ANE) is a rare and potentially life-threatening complication of diabetic ketoacidosis (DKA). While its association with DKA is established, specific clinical characteristics that predict ANE in DKA patients remain less understood. This study aimed to identify these characteristics by analyzing data from 30 DKA patients admitted from January 2018 to September 2022. Seven patients in this study presented with ANE, forming the ANE group. The remaining 23 constituted the non-ANE group. We compared the clinical parameters and computed tomography (CT) between the groups. The mean age of participants was 57.7 ± 20.4 years, and their mean HbA1c was 11.1 ± 3.3%. Notably, ethanol intake was significantly higher in the ANE group (44.4 ± 25.4 g/day) compared to the non-ANE group (6.8 ± 14.0 g/day; p = 0.013). Additionally, sodium-glucose transport protein 2 inhibitor use was significantly more prevalent in the ANE group (p = 0.013). Gastrointestinal symptoms were also significantly more pronounced in the ANE group, with vomiting occurring in 85.7% of patients compared to only 13.0% in the non-ANE group. Admission CT scans revealed further distinguishing features, with the ANE group showing significantly higher rates of esophageal wall thickening, intra-esophageal effusion, and calcification of the celiac artery origin (p < 0.0001, 0.0038, 0.0038, respectively). In conclusion, our study suggests that heavy alcohol consumption and strong gastrointestinal symptoms in DKA patients warrant a heightened suspicion of ANE. Early consideration of CT or upper gastrointestinal endoscopy is recommended in such cases.

Esophageal infection by Candida spp. is a common opportunistic entity in immunocompromised hosts; however, systemic fungal dissemination due to perforation or transmural necrosis, also known as necrotizing Candida esophagitis (NCE), is rare. We report the case of a 61-year-old male patient with diagnosed ankylosing spondylitis, severe arteriosclerosis, and vasculitis under immunosuppressive therapy who presented NCE with fungal and bacterial septicemia diagnosed at autopsy. Necrotizing esophagitis is a rare manifestation of Candida infection, which may be a final complication in severely ill patients. Unfortunately, it may be underdiagnosed, and we call attention to this devastating complication in patients with leukocytoclastic cutaneous vasculitis and ankylosing spondylitis.

ABSTRACT Background: The Helicobacter pylori infection (HP) is related to the development of gastric lesions and lymphoma; however, it is not known if there is a relation with gastroesophageal reflux disease and reflux esophagitis. Aim: To evaluate HP's relationship with esophagitis in patients undergoing upper endoscopy. Methods: Observational, retrospective and cross-sectional study, being evaluated 9576 patients undergoing outpatient endoscopic examination during the period between January and December 2015. Were included patients with any esophageal alteration at the examination; greater than 18; of both genders; independent of the complaint or the reason for the examination, illness or drug use. Were excluded those with active bleeding during the examination and in use of anticoagulants. The variables gender, age, esophagitis and result of the urease test, were studied. For statistical analysis was used the Epi Info software 7.1.5.2. Results: Most of the samples consisted of women and the overall average age was 46.54±16.32 years. The presence of infection was balanced for gender: 1204 (12.56%) women and 952 (13.92%) men. Relating degree of esophagitis HP- and HP+ was observed that the type A was the most common (58.79%, n=1460); 604 (24.32%) had grade B; 334 (13.45%) grade C, and 85 (3.42%) grade D. In the relation between the grade of esophagitis with gender, esophagitis A was predominant in women and present in 929 (63.33%), followed by type B, 282 (46.68%), 136 C (40.71%) and D 30 (35.29%). In men 531 (36.36%) showed type A, 322 (53.31%) B, 198 (59.28%) C, and 55 (64.70%) D. Among the groups 40-50 and over 60 years there was a significant difference in whether have or not have HP+. Conclusion: There is no significant difference between HP infection and the different grades of esophagitis.
RESUMO Racional: A infecção pelo Helicobacter pylori (HP) é relacionada com o desenvolvimento de lesões e linfoma gástricos; porém, ainda não se sabe ao certo se há relação dele com a doença do refluxo gastroesofágico e esofagite de refluxo. Objetivo: Avaliar a relação do HP com as esofagites em pacientes submetidos à endoscopia digestiva alta. Métodos: Estudo observacional, retrospectivo e transversal, sendo avaliados 9576 pacientes submetidos ao exame endoscópico ambulatorial durante o período compreendido entre janeiro e dezembro de 2015. Foram incluídos pacientes que apresentaram alguma alteração esofágica ao exame; maiores que 18 anos; de ambos os gêneros; independente da queixa ou da razão para a realização do exame, doença ou uso de medicamentos. Excluíram-se os com sangramento ativo durante o exame e em uso de anticoagulantes. Foram avaliadas as variáveis gênero, idade, esofagite e resultado do teste da urease. Para a análise estatística utilizou-se o software Epi Info 7.1.5.2. Resultados: A maioria das amostras foi composta por mulheres e a idade média geral foi de 46,54±16,32 anos. A presença da infecção foi equilibrada para a variável gênero: 1204 (12,56%) mulheres e 952 (13,92%) homens. Relacionando os graus da esofagite com HP+ e HP- observou-se que o tipo A foi o mais comum (58,79% da amostra, n=1460), que 604 (24,32%) possuíam o grau B; 334 (13,45%) o grau C e 85 (3,42%) o grau D. Já na relação entre os graus de esofagite com o gênero, a esofagite A foi predominante nas mulheres e presente em 929 (63,33%), seguido pelo tipo B, com 282 (46,68%), C com 136 (40,71%) e D com 30 (35,29%) mulheres. Nos homens 531 (36,36%) apresentam o tipo A, 322 (53,31%) o B, 198 (59,28%) o C e 55 (64,70%) o D. Entre os grupos de 40 a 50 anos e acima de 60 anos houve diferença significativa em ter ou não HP+. Conclusão: Não há diferença significativa entre infecção por HP nos diferentes graus de esofagite.

ABSTRACT Background: The influence of Helicobacter pylori (HP) in inflammatory disorders of the digestive mucosa has been the subject of several studies since socioeconomic, personal and environmental factors were implicated in the bacteria transmission. Aim: To correlate the inflammatory endoscopic findings with HP infection and the onset of mucosal diseases mucous of the upper digestive tract. Method: Comparative observational study, in which were collected data from 2247 patients who underwent upper endoscopy and biopsies for HP with urease test. The patients were divided into two groups: HP+ and HP- (control) in which endoscopic findings were observed for the following changes: esophagitis, esophageal ulcer, gastritis, erosive gastritis, gastric ulcer, bulboduodenitis, bulbar ulcer and without disease. Results: As for esophagitis, there was little disparity in the distribution favorable to HP+ group (HP+ =67.11% and HP- =69.89%) and esophageal ulcer (HP+ =0% and HP- =0, 21%). Gastritis was favorable to HP- group (HP+ =78.34% and HP- =73.63%), as well as erosive gastritis (HP+ = 67,11% and HP- = 64,55%), in bulboduodenitis (HP+ =1,87% and HP- 1,23%), in gastric ulcer (HP+ =2,14% and HP- =2,03%) and in the absence of alterations in the HP+ group (4.81%) with the HP- control group (6,30%), in which there was little disproportion in favor of HP- group, but without statistical significance. As for the bulbar ulcer (HP +=10.16% and HP- =4.48%), there was statistically significant (p=0.00001). Conclusion: There is no difference between HP+ and HP- groups in inflammatory changes in endoscopic gastroduodenal mucosa, except for the relationship between HP and bulbar ulcer.
RESUMO Racional: A influência do Helicobacter pylori (HP) nas alterações inflamatórias das mucosas digestivas tem sido objeto de vários estudos uma vez que fatores socioeconômicos, pessoais e ambientais são implicados na transmissão da bactéria, facilitando-a. Objetivo: Relacionar os achados inflamatórios endoscópicos com a infecção pelo HP e o aparecimento de doenças mucosas do trato digestivo alto. Método: Estudo observacional comparativo, o qual foram coletados dados de 2247 pacientes submetidos à endoscopia digestiva alta e biópsias para HP com teste de urease. Os pacientes foram divididos em dois grupos: HP+ e o controle HP-dentro dos quais foram observados os achados endoscópicos referentes às seguintes alterações: esofagite, úlcera esofágica, gastrite, gastrite erosiva, úlcera gástrica, bulboduodenite, úlcera bulbar e sem doença. Resultados: Quanto à esofagite, observou-se pequena desproporção na distribuição, favorável ao grupo HP+ (HP+ =67,11% e HP- =69,89%) bem como na úlcera esofágica (HP+ =0% e HP- =0,21%). Na gastrite foi favorável ao grupo HP- (HP+ =78.34% e HP- =73.63%), assim como na gastrite erosiva (HP+ = 67,11% e HP- = 64,55%), na bulboduodenite (HP+ = 1,87% e HP- 1,23%), na úlcera gástrica (HP+ =2,14% e HP- =2,03%) e na ausência de alterações no grupo HP+ (4.81%) com o grupo controle HP- (6,30%), nos quais há pequena desproporção favorável ao grupo HP-, porém, sem significância estatística. Já quanto à úlcera bulbar (HP+ =10,16% e HP- =4,48%), houve significância estatística (p=0,00001). Conclusão: Não há diferenciação entre os grupos HP+ e HP- nas alterações endoscópicas inflamatórias na mucosa gastroduodenal, exceto para a relação entre HP e úlcera bulbar.

Pegylated liposomal doxorubicin is an important antineoplastic agent with activity in a variety of solid tumors. It has a totally different profile of pharmacokinetics and toxicity compared with doxorubicin. It rarely causes side-effects like cardiotoxicity or hair loss, but frequently results in many kinds of mucocutaneous reactions, including palmar-plantar erythrodysesthesia, diffuse follicular rash, intertrigo-like eruption, new formation of melanotic macules, stomatitis and radiation recall dermatitis. We present a rare case of multiple myeloma who immediately developed serious stomatitis and esophatitis associated with minor palmar-plantar erythrodysesthesia after a single course of pegylated liposomal doxorubicin.

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.

Background:Obesity is correlated with several comorbidities, including gastroesophageal reflux disease. Its main complications are detectable by endoscopy: erosive esophagitis and Barrett's esophagus.Aim: To correlate erosive esophagitis and hiatal hernia with the degree of body mass index (BMI).Method: Was performed a retrospective analysis of 717 preoperative endoscopic reports of bariatric patients. Fifty-six (8%) presented hiatal hernia, being 44 small, nine medium and five large. Esophagitis was classified by Los Angeles classification.Results: There was no correlation between the presence and dimension of hiatal hernia with BMI. One hundred thirty-four (18.7%) patients presented erosive esophagitis. Among them, 104 (14.5%) had esophagitis grade A; 25 (3.5%) grade B; and five (0.7%) grade C. When considering only the patients with erosive esophagitis, 77.6% had esophagitis grade A, 18.7% grade B and 3.7% grade C. Were identified only two patients with Barrett's esophagus (0,28%).Conclusion: There was a positive correlation between the degree of esophagitis with increasing BMI.
Racional:A obesidade está correlacionada com diversas comorbidades, dentre elas a doença do refluxo gastroesofágico. Ela tem como um de seus principais desencadeantes a hérnia do hiato, e como suas principais complicações a esofagite erosiva e o esôfago de Barrett.Objetivo: Correlacionar o grau do índice de massa corporal (IMC) com a presença e tamanho da hérnia hiatal, e com a presença e gravidade da esofagite erosiva e esôfago de Barrett.Método: Foi realizada análise retrospectiva de laudos endoscópicos pré-operatórios de 717 pacientes submetidos à cirurgia bariátrica. A hérnia de hiato esteve presente em 56 pacientes (8%), sendo que delas 44 eram pequenas, nove médias e cinco grandes. O grau da esofagite obedeceu o preconizado pela Classificação de Los Angeles.Resultados: Não houve correlação entre a presença ou tamanho da herniação hiatal com o IMC. Dos pacientes avaliados, 134 (18,7%) apresentavam esofagite erosiva. Dentre elas 104 (14,5%) eram grau A; 25 (3,5%) grau B e cinco (0,7%) grau C. Considerando-se apenas os portadores de esofagite erosiva, 77,6% eram grau A; 18,7% grau B; e 3,7% grau C. Foram identificados apenas dois casos de esôfago de Barrett (0,28% da amostra total).Conclusão: Observou-se correlação positiva entre o grau de esofagite com o aumento do IMC.

Early dilatation in caustic esophagitis is not well established. Objective: Evaluate the benefits of early dilatation in the evolution and complications of grade I and II caustic esophagitis in children. Patients and Methods: Prospective study of 32 children, group A (early dilatation) and B (late dilatation). The periodic dilatation index was used to evaluate the benefits of early dilatation. Results: Average age 2,3 years old; 13 (40,62%) female and 19 (59,38%) male; 21/32 (65,62%) developed esophageal stenosis. 6/15 (40,00%) group A, 15/17 (88,23%) group B (p=0,0041). Simple stenosis in 12/21 (57,14%), complex 9/21 (42,85%), recurrent 2/6 and refractory 2/6, group A; 6/15 recurrent and 5/15 refractory, 1/15 esophageal perforation, group B. The average of dilatation sessions was 17 vs. 44,6 (p=0,0297) and periodic dilatation index was 3,04 vs. 4,11 (p=0.0002) group A and B respectively. Conclusions: early dilatation in caustic esophagitis is safe and contributes to decrease the number of dilatation sessions and complications.

La esofagitis necrotizante aguda (ENA), también denominada esófago negro, es una rara enfermedad poco descripta en la literatura médica. Describimos el caso de un hombre de 80 años, con hemorragia digestiva alta quien desarrolló un esófago negro luego de un episodio de hipotensión. La necrosis fue confirmada histológicamente. Los pacientes se presentan con hematemesis y melena en más del 70% de los casos. Los hallazgos endoscópicos muestran una coloración negruzca de la mucosa esofágica. El diagnóstico se realiza con endoscopia y confirmación histológica. La mortalidad es alta (más del 50%) aunque relacionada a las enfermedades de base del paciente. Por último, podemos decir que la sospecha es muy importante en el diagnóstico de ENA, particularmente en pacientes ancianos con enfermedades asociadas y evidencia de hemorragia digestiva alta. En este trabajo describimos las características clínicas, endoscópicas e histopatológicas de un paciente con ENA.
Acute esophageal necrosis (AEN), also designated black esophagus, is a rare disorder that is poorly described in the medical literature. We present the case of an 80 years old man, with upper gastrointestinal bleeding who developed a black esophagus after hypotensive episodes. Necrosis was confirmed histologically. Hematemesis and melena are present in more than 70% of the cases. Endoscopic findings show black discoloration of the distal esophagus with proximal extension ending sharply at the gastroesophageal junction. Diagnosis is reached endoscopically with histological support. Mortality is high (up to 50%) even though related to the patient's underlying condition. Finally, we may say that to keep in mind the posibility of AEN is a key factor in its diagnosis, particularly in older patients with associated morbidity and evidence of upper gastrointestinal bleeding. In the present report we describe the clinical, endoscopic and histophatological characteristics of a patient with a diagnosis of AEN.

Presentamos el caso de una mujer de 42 años, obesa, con reflujo gastroesofágico patológico (RGEP) y una hernia hiatal por deslizamiento diagnosticada el año 2004. Desde entonces ha recibido omeprazol en forma discontinuada. Durante el 2007 los síntomas de RGEP se hacen más intensos e intolerables el último mes, con aumento de la pirosis, epigastralgia y dolor al pecho. La panendoscopia demuestra alteraciones características de esofagitis eosinofílica con aspecto anillado del esófago, surcos longitudinales y grumos blanquecinos. Las biopsias escalonadas del esófago confirman el diagnóstico con más de 20 eosinófilos intraepiteliales por campo de mayor aumento (CMA) y las biopsias de estómago y duodeno prácticamente no presentan eosinófilos. Las claves para el diagnóstico endoscópico e histopatológico se cumplen perfectamente en este caso.
We present an obese, 42 year-old lady, with gastro-esophageal reflux and a sliding hiatal hernia diagnosed in 2004. Since then she has been treated with Omeprazole. Since 2007 the gastro-esophageal reflux symptoms have become more severe. By a month ago the symptoms became intolerable with increased heartburn, epigastric and chest pain. The upper endoscopy showed characteristic changes of eosinophilic esophagitis with esophageal ringed appearance, longitudinal ridges and whitish spots. Serial biopsies of the esophagus confirmed the diagnosis with more than 20 intraepithelial eosinophils per field higher magnification (CMA) and biopsies of stomach and duodenum showed practically no eosinophils. The keys to the endoscopic and histopathological diagnosis are fulfilled in this case.

Introducción: La ingestión de sustancias cáusticas (IC) en niños, continúa siendo un campo difícil, debido a la poca clara relación entre los signos y síntomas y la extensión del daño del esófago.Objetivo: Describir el caso de un niño con IC y revisar la literatura del tema. Reporte del caso: Se trata de un masculino de 1 año 8 meses de edad, sin antecedentes de importancia, quien luego de ingesta accidental de líquido de radiador contenido en un frasco de yogurt, presenta vómito en 15 oportunidades. En Centro de Salud luego de la colocación de sonda nasogástrica para lavado gástrico es remitido a un Tercer Nivel de Atención, donde se le realiza una endoscopia digestiva alta (EVDA) luego de 28 horas de la IC. El reporte de la EVDA, indicó esofagitis caústica grado IIc, gastropatía severa, y píloro no franqueable con lesiones concéntricas. El manejo incluyó ayuno, líquidos endovenosos, corticoides, penicilina, y ranitidina Discusión: La EVDA, es el método más eficiente para evaluar la mucosa del tubo digestivo superior luego de la IC, que puede tener efectos catastróficos o puede resultar inofensiva. Se ha intentado correlacionar los signos y síntomas iniciales con la gravedad de las lesiones para evitar la realización de una EVDA innecesaria, sin embargo, sigue siendo controversial este tema. El manejo médico de la IC incluye antibióticos, esteroides y bloqueadores H2. Entre las complicaciones de la IC se encuentran la perforación, la mediastinitis, las fístulas a grandes vasos, la penetración al estómago y las estenosis.
Introduction: The ingestion of caustic substances (CI) in children, remains a difficult, due to lack clear relationship between the signs and symptoms and the extent of damage of the esophagusObjective: To describe the case of a child with CI and review the literature on the subject. Case report: This is a male 1 year 8 months old, with no previous medical history, who after accidental ingestion of radiator fluid contained in a jar of yogurt, vomiting occurs in 15 opportunities. Health Center after placement of a nasogastric tube for gastric lavage is referred to a tertiary care, where she underwent an upper endoscopy (UE) after 28 hours of the CI. The report of the UE, said caustic esophagitis grade IIc, severe gastropathy, and pylorus not passable with concentric lesions. The managemen included fasting, intravenous fluids, steroids, penicillin, and ranitidine Discussion: . The UE, is the most efficient method to evaluate the upper gastrointestinal mucosa after the IC, which can have catastrophic effects and can be harmless. It has tried to correlate the signs and symptoms with the severity of injuries to avoid making an unnecessary UE, however, this issue remains controversial. The medical management of IC including antibiotics, steroids and H2 blockers. Complications of the IC are perforation, mediastinitis, fistulas to large vessels, penetrationto the stomach and stenosis.

Eosinophilic esophagitis in adults (EE) is a disease of unknown cause, characterized by symptoms such as reflux and dysphagia that traditionally do not respond to antacid treatment. It affects mostly young men with a strong personal or familial history of a topy asthma and allergies. We repot three male patients aged 10, 14 and 15years, all with symptoms of dysphagia, two of them with chest pain caused by spasm of the esophagus, with heterogeneous endoscopic findings which included from leucoplakia to stenosis that needed endoscopic dilatation. All of them had abnormal findings in immunity studies (prick test or IgE levels). They received treatment based on diet measures, acid suppression and leukotriene inhibitors, with satisfactory clinical, endoscopic and histological response. EE should be suspected in children and adults with esophageal symptoms and personal or family history of allergy and asthma.
