Background: Among the microorganisms corresponding to the genus Acinetobacter, Acinetobacter johnsonii is a species of low epidemiological incidence compared to Acinetobacter baumannii. However, it has a comparable infectious capacity since it can be involved in severe diseases like bacteremia or meningitis. Its habitat is variable, usually found in humid tropical climates (as is the case in Colombia), soil, water, or animal reservoirs. It is still an unknown germ for most health personnel, as there are not many reported cases, and information about its microbiological and epidemiological characteristics is still scarce, making its identification and treatment difficult. Clinical case: We describe the case of A. johnsonii infection of the central nervous system in a 15-year-old female, as well as the diagnostic method used, the course of the disease, medical management, and clinical outcome. Conclusions: It is of utmost importance to report this type of microorganisms to facilitate early diagnosis and appropriate treatment. More scientific publications of this type are needed to broaden the knowledge about these microorganisms.
lo cual produce hipoglucemias graves persistentes. Esta alteración puede tener importantes secuelas neurológicas debido al daño irreversible que se produce en la neurona por la exposición a la hipoglucemia por cortos periodos de tiempo. Su diagnóstico no es sencillo y requiere un alto índice de sospecha. El tratamiento se establece de manera secuencial, en varias etapas, observando la respuesta a cada uno de los posibles medicamentos empleados. En caso de que falle el manejo farmacológico, se requieren procedimientos quirúrgicos. Serie de casos: Se presentan siete casos de hiperinsulinismo congénito que fueron diagnosticados en los últimos 7 años en el Instituto Roosevelt en Bogotá, Colombia. En este país, el radiotrazador empleado usualmente durante la tomografía por emisión de positrones (PET/TC) no se encuentra disponible. Sin embargo, en uno de los casos descritos fue posible emplear otro radiotrazador alternativo que permitió un adecuado diagnóstico y un tratamiento quirúrgico exitoso. Conclusiones: El hiperinsulinismo congénito es una condición clínica compleja que amerita un correcto diagnóstico y un apropiado manejo, con el objetivo de evitar el daño neurológico que producen las hipoglucemias persistentes. Es posible emplear PET/TC con un radiotrazador adecuado para realizar un diagnóstico oportuno y proporcionar la mejor opción terapéutica disponible.
Background: Mesenteric cysts are intra-abdominal masses of congenital origin, which most frequently occur in children, with an incidence of approximately 1 case per 20,000 pediatric admissions. Its progression can be asymptomatic, and its diagnosis can be incidental. However, it usually occurs with symptoms such as nausea, vomiting, constipation, sensation of a mass, and/or diarrhea. The diagnostic imaging method of choice is abdominal ultrasound. Case presentation: Below, we present the case of a previously healthy 1-year-old male patient with nonspecific symptoms, who was referred to a tertiary hospital. The presence of a mesenteric cyst was detected at the end of the diagnostic approach. Conclusion: It is important to know these pathologies even though they are infrequent, because although they are benign masses by definition, they can lead to complications such as intestinal torsion, intestinal obstruction, and even peritonitis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
