RESUMO
We report the observations of two patients, having voluntarily ingested lethal doses of paraquat with suicidal intent, with an unfavorable prognostic score. The treatment consisted of gastric lavage, administration of activated charcoal, n-acetylcysteine and cyclophosphamide + methylprednisolone + dexamethasone. The installation of acute renal failure motivated the initiation of daily conventional hemodialysis (HD) over 10 to 14 days, with a favorable evolution. The following complications were recorded: anemia, bacteremia and deep vein thrombosis. These observations raise three questions in the treatment of paraquat intoxication: the effectiveness of HD, the interest of its association with the above therapies in the prevention of pulmonary fibrosis, and the need for infectious prevention and thromboembolism. Furthermore, the absence of a paraquatemia assay cannot constitute a limitation for management, and hemoperfusion on an inaccessible charcoal column can be replaced by an HD usually available.
Nous rapportons les observations de deux patients ayant ingéré volontairement des doses létales du paraquat à but suicidaire, avec un score pronostic défavorable. Le traitement a consisté en un lavage gastrique, une administration du charbon activé, du n-acétylcystéine et du cyclophosphamide + méthylprednisolone + dexaméthasone. L'installation d'une insuffisance rénale aiguë a motivé l'initiation d'une hémodialyse conventionnelle quotidienne (HD) sur 10 à 14 jours, avec une évolution favorable. Les complications suivantes ont été enregistrées : anémie, bactériémie et thrombose veineuse profonde. Ces observations soulèvent trois questions dans le traitement d'une intoxication au paraquat : l'efficacité de l'HD, l'intérêt de son association avec les thérapeutiques supra dans la prévention de la fibrose pulmonaire, et la nécessité d'une prévention infectieuse et thrombo-embolique. Par ailleurs, l'absence d'un dosage de la paraquatémie ne peut constituer une limite pour la prise en charge, et l'hémoperfusion sur colonne de charbon non accessible peut être remplacée par une HD habituellement disponible.

Objetivo: este estudio busca describir los individuos evaluados por sobredosis de acetaminofén entre 2019 y 2020 en un centro de referencia de trasplante hepático en Colombia. Metodología: estudio derivado del análisis secundario de historias clínicas entre el 1.º de enero de 2019 y el 31 de diciembre de 2020. Los criterios de inclusión abarcan individuos con ingestión aguda y voluntaria de dosis tóxicas de acetaminofén (>4 g/día). Resultados: sesenta y tres casos, 68% mujeres, 67% menores de 18 años y 54% estudiantes. Reportó historia personal de enfermedad psiquiátrica el 60% y el 35% al menos un intento de suicidio previo. La mediana de dosis de acetaminofén fue 15g, 46% refirieron co-ingesta de otras sustancias y 13% estaba bajo efecto de sustancias psicoactivas. El 57% tenía la intención clara de suicidarse, así como 81% vomitó antes de acudir al servicio de urgencias, 22% recibió medidas de descontaminación y 10% no recibió N - acetilcisteína. Quince individuos desarrollaron lesión hepática aguda, nueve con criterios de severidad. Conclusiones: la población era predominantemente joven, la historia de enfermedad psiquiátrica fue muy prevalente y la mayoría refirieron un evento vital que explicara el comportamiento impulsivo de consumo. Ninguno desarrolló criterios para trasplante hepático, lo cual podría explicarse por la edad de los individuos, los episodios de vómito temprano, y la ausencia de enfermedad hepática crónica o de consumo de sustancias hepatotóxicas.
Objective: this study aims to describe patients with overdose intake of acetaminophen between 2019 and 2020 at a reference center for liver transplantation in Colombia. Methodology: study derived from a secondary analysis of the clinical records between January 1st, 2019, to December 31st, 2020. Inclusion criteria were individuals with voluntary acute ingestion of toxic doses of acetaminophen (>4 g/day). Results: sixty-three cases, 68% women, 67% <18-year-old, and 54% students. 60% had personal history of psychiatric illness and 35% reported at least one previous suicide attempt. The median dose of acetaminophen was 15g, 46% referred to co-ingestion with other substances and 13% were under the effect of any psychoactive substance. 57% had a clear intention of suicide. 81% vomited before the arrival to the emergency room, 22% received decontamination intervention with gastric lavage or activated charcoal, and 10% did not receive any dose of N-Acetylcysteine. Fifteen individuals developed an acute liver injury, nine with severity criteria. Conclusions: the population was predominantly young, the personal history of psychiatric disease was highly prevalent, and most of the cases referred a vital event that explains the impulsive behavior in acetaminophen consumption. None developed criteria for liver transplantation, and this could be explained by the young age of the individuals, the episodes of early vomiting, and the absence of chronic liver disease or hepatotoxic substance consumption.

BACKGROUND: We aimed to determine whether the Xpert MTB/RIF (Xpert) assay is a useful adjunct to culture for the rapid diagnosis of tuberculosis (TB) using gastric lavage aspirates (GLAs) in children aged < 5 years. METHODS: We reviewed the yield from diagnostic modalities in children suspected of having TB followed at an infectious disease research and treatment center in Port-au-Prince, Haiti, from 2011 to 2016. RESULTS: In 187 children clinically diagnosed with TB, a microbiologic diagnosis could be established in 40 (21%). Cultures, Xpert, and smears were positive in 30 (19%), 28 (17%), and 3 (1.6%) children, respectively. Ten cases that would not have been diagnosed by culture alone were found by the use of the Xpert assay. Collecting 2 GLA samples optimized microbiologic yield. CONCLUSIONS: In GLAs, Xpert increased the yield of microbiologically documented cases by 33%. Additionally, the rapidity of diagnosis potentially makes Xpert a valuable adjunct in initiating treatment for TB in children. Smear microscopy has low sensitivity in GLA and did not add to the documented cases. Our findings also highlight the low rate of microbiologic confirmation of clinically diagnosed TB.

Objetivo: Avaliar a indicação da lavagem gástrica no tratamento de intoxicações causadas por ingestão. Métodos: Todos os casos de intoxicação causada por ingestão que foram atendidos em dois hospitais do interior de São Paulo e submetidos à lavagem gástrica no período de 1° de janeiro de 2011 a 31 de dezembro de 2015 foram avaliados retrospectivamente quanto à indicação do procedimento, considerando o tempo entre ingestão e atendimento, a toxicidade da substância e as contraindicações para o procedimento. Resultados: Dos 587 casos atendidos, 338 (57,6%) foram submetidos à lavagem gástrica. Dentre esses casos, constatou-se a realização equivocada do procedimento em 95,8% casos. Conclusão: O número de pacientes submetidos à lavagem gástrica neste trabalho foi considerado elevado, mesmo quando orientado pelo centro de atendimento. Apesar da falta de evidências de que a lavagem gástrica traga benefícios nos casos de intoxicação, ela é largamente utilizada em virtude do desconhecimento das indicações e contraindicações desse procedimento por parte dos profissionais de saúde
Objective: To evaluate the indication of gastric lavage in the treatment of poisoning caused by ingestion. Methods: All cases of poisoning caused by ingestion that were treated in two hospitals in inland cities of São Paulo and subjected to gastric lavage from January 1, 2011 to December 31, 2015 were retrospectively assessed as for the indication of the procedure, considering the time between ingestion and care, substance toxicity, and procedure contraindications. Results: Of the 587 cases treated, 338 (57.6%) underwent gastric lavage. The procedure was considered incorrect in 95.8% of cases. Conclusion: The number of patients undergoing gastric lavage in this study was considered high, even when instructed by the center of attendance. Despite the lack of evidence that gastric lavage brings benefits in cases of poisoning, it is widely used due to the lack of knowledge by health professionals of the indications and contraindications of this procedure.

The presence of bezoars in daily clinical practice is a event that poses a challenge both diagnostic, due to the associated factors in its development, as well as therapeutic. The management of this entity is associated with medical, endoscopic and surgical procedures and it is necessary to know its usefulness in different clinical scenarios. The role of carbonated beverages is increasingly accepted given its low cost, wide availability and high efficiency. For the aforementioned, it seems important to report a series of cases and the management performed.

Intraperitoneal free cancer cells in gastric adenocarcinoma are associated with a poor outcome. However, the true prognostic value of intraperitoneal free cancer cells is still unclear, leading to a lack of consensus in the management of gastric cancer. The aim of the present study is to perform a systematic review and meta-analysis to analyze intraperitoneal free cancer cells-positive patients with regard to tumor oncologic stage, recurrence, grade of cellular differentiation, and survival rates and to analyze the clinical significance of intraperitoneal free cancer cells with regard to prognosis. Databases were searched up to January 2016 for prognostic factors associated with intraperitoneal free cancer cells, including oncologic stage, depth of neoplasm invasion, lymph nodal spread, differentiation grade of the tumor, and recurrence and survival rates. A total of 100 studies were identified. Meta-analysis revealed a clear association between intraperitoneal free cancer cells and a poor prognosis. intraperitoneal free cancer cells -positive patients had higher rates of nodal spread (risk difference: 0.29; p<0.01), serosal invasion (risk difference: 0.43; p<0.01), recurrence (after 60 months of follow-up, risk difference: 0.44; p<0.01), and mortality (after 60 months of follow-up, risk difference: 0.34; p<0.01). Intraperitoneal free cancer cells are associated with a poor outcome in gastric cancer. This surrogate biomarker should be used to guide therapy both prior to and after surgery.

The presence of foam and bubbles during upper gastrointestinal endoscopy (UGE) obscures the view of gastric lesions. Objective: To assess the confidence of a gastric cleansing scale in UGE. Methods: Prospective, multicenter study. The instrument was administered to patients undergoing a UGE examination. For the gastric visualization scale, the stomach was divided in 4 parts and a 1-4 scale was used to classify each part, with a total score of 4 (optimal view of gastric mucosa) and 16 (poor view of gastric mucosa), assessed by 2 independent endoscopists. An initial cleansing score was obtained and later, after cleansing of each studied section, and total. Inter-observer concordance was established by means of Kappa test, and the agreement on the global cleansing score was established with the Bland-Altman plot. Results: 53 patients went under UGE, with an average age of 48,7 years and 62,3 percent female subjects. The main indication for performing the UGE examination was gastroesophageal reflux disease (GERD) (32.1 percent). Average duration of the procedure was 13.6 minutes. The average total gastrointestinal view before cleansing with water was 6.26 points (scale from 4 to 16) and 5.1 points (p < 0.001) after cleansing. 37.7 percent required at least 50 cc of water for cleansing. The difference in the pre and post cleansing score inter-observers was no different of 0. Kappa value obtained in gastric fundus, upper body, lower body and antrum before cleansing was 0.81; 0.71; 0.9 and 0.8, respectively. Kappa value obtained after cleansing of gastric fundus, upper body, lower body and antrum was 0.84; 0.65; 0.81 and 0.78; respectively. The mean difference between inter-observer scores before cleansing was 0.08 (p = 0.51), and after cleansing, 0.02 (p = 0.78)...
La presencia de espuma y burbujas durante la endoscopia digestiva alta (EDA) es una limitante para la visualización de lesiones gástricas. Objetivo: Evaluar la confiabilidad de una escala de clasificación de limpieza gástrica en EDA. Métodos: Estudio prospectivo, multicéntrico. Se aplicó el instrumento a pacientes que estaban agendados para EDA. Para la clasificación de visualización gástrica, el estómago se dividió en 4 porciones y se utilizó una escala de 1 a 4 por porción, sumando un puntaje total entre 4 (óptima visualización de la mucosa) y 16 (pobre visualización de ésta), evaluada por 2 endoscopistas independientes. Se obtuvo un puntaje de limpieza inicial y luego de la limpieza con agua de cada segmento estudiado y total. La concordancia inter-observador se estableció por medio del test de Kappa y el acuerdo para el puntaje global de limpieza fue establecido mediante el gráfico de Bland-Altman. Resultados: 53 pacientes fueron sometidos a EDA, con edad promedio de 48,7 años y 62,3 por ciento de sexo femenino. La principal indicación de EDA fue enfermedad por reflujo gastroesofágico (32,1 por ciento). El tiempo promedio del procedimiento fue 13,6 min. El promedio de visualización gástrica total previo a limpieza con agua fue de 6,26 puntos (escala 4 a 16) y post limpieza 5,1 puntos (p < 0,001). Para la limpieza el 37,7 por ciento requirió al menos 50 cc de agua. La diferencia de puntaje de visualización pre y post limpieza inter observador no fue distinta de 0. En fondo gástrico, cuerpo alto, cuerpo bajo y antro se obtuvo un valor de Kappa previo a limpieza de 0,81; 0,71; 0,9 y 0,8, respectivamente. El valor de Kappa posterior a limpieza en fondo gástrico, cuerpo alto, cuerpo bajo y antro fue 0,84; 0,65; 0,81 y 0,78, respectivamente. La diferencia media de los puntajes inter-observadores previos a la limpieza gástrica fue de 0,08 (p = 0,51) y posterior a la limpieza gástrica fue de 0,02 (p = 0,78)...

OBJECTIVES: to evaluate and indicate the procedure to be followed in the health unit, both for diagnosis and the treatment of acute exogenous intoxications by carbamates or organophosphates. METHODS: a descriptive study based on retrospective analysis of the clinical history of patients diagnosed with intoxication by carbamates or organophosphates admitted at the emergency unit of the Hospital de Urgências de Sergipe Governador João Alves (HUSE) between January and December of 2012. Some criteria were evaluated, such as: intoxicating agent; patient's age and gender; place of event, cause, circumstances and severity of the intoxication; as well as signs and symptoms of the muscarinic, nicotinic and neurological effects. RESULTS: seventy patients (average age: 25 ± 19.97) formed the study's population. It was observed that 77.14% of them suffered carbamate intoxication. However, organophosphate intoxications were more severe, with 68.75% of patients presenting moderate to severe forms. Suicide attempt was the leading cause of poisoning, with 62 cases (88.57% of total). Atropine administration was an effective therapeutic approach for treating signs and symptoms, which included sialorrhea (p = 0.0006), nausea (p = 0. 0029) and emesis (p < 0.0001). The use of activated charcoal was shown effective, both in combating the signs and symptoms presented by both patient groups (p < 0.0001). CONCLUSION: it is concluded that the use of atropine and activated charcoal is highly effective to treat the signs and symptoms developed by patients presenting acute exogenous intoxication by carbamates or organophosphates.

Resumo Objetivo: avaliar e indicar os procedimentos a serem seguidos na unidade de saúde tanto para o diagnóstico como para o tratamento de intoxicações agudas exógenas por carbamatos ou organofosforados. Métodos: estudo descritivo baseado na análise retrospectiva da história clínica de pacientes diagnosticados com intoxicação por carbamatos ou organofosforados admitidos em uma unidade de emergência, entre janeiro e dezembro de 2012. Foram avaliados alguns critérios, como: agente intoxicador; idade do paciente e gênero; causa de envolvimento, circunstâncias e gravidade da intoxicação; sinais e sintomas dos efeitos neurológicos muscarínicos e nicotínicos. Resultados: setenta pacientes (idade média: 25±19,97 anos) formaram a população de estudo. Foi observado que 77,14% deles sofreram intoxicação por carbamatos. Os casos mais graves foram intoxicados por organofosforados, com 68,75% dos pacientes apresentando formas moderadas a graves. Tentativa de suicídio foi a causa principal de envenenamento, com 62 casos (88,57% do total). A administração de atropina foi uma medida terapêutica efetiva para tratamento de sinais e sintomas, como sialorreia (p=0,0006), náusea (p=0,0029) e êmese (p<0,0001). O uso do carvão ativado mostrou efetividade para o combate dos sinais e sintomas apresentados por pacientes em geral (p<0,0001). Conclusão: o uso de atropina e de carvão ativado é uma medida terapêutica altamente efetiva para combater os sinais e sintomas apresentados por pacientes vítimas de intoxicação aguda exógena por carbamatos ou organofosforados.
