RESUMO

BACKGROUND: Esophageal foreign body (EFB) and impaction are common gastrointestinal emergencies. Detection with standard imaging can be challenging. Computed tomography is a commonly used non-invasive imaging modality, but is not 100% sensitive and not always feasible. Sensitivity of plain film x-ray varies widely and the addition of a barium swallow can obscure evaluation by subsequent esophagogastroduodenoscopy (EGD). Use of emergency ultrasound (EUS) for detection of EFB in adults has not been previously studied. OBJECTIVE: To evaluate the role of EUS in detection of EFB and to characterize sonographic findings. METHODS: A case control series of five patients with clinical suspicion of EFB underwent EUS, and findings were compared to five healthy controls. Patients were evaluated for persistent air-fluid levels after swallowing, esophageal dilatation, and visualization of EFB. RESULTS: All patients with suspected EFB had esophageal dilatation (17.5mm vs 9.3mm in healthy controls; p=0.0011) and persistent air-fluid levels after swallowing. EFB was visualized on EUS in 60% of patients. All patients had EFB confirmed on EGD except one, who vomited a significant food bolus during EUS and prior to EGD. CONCLUSION: In patients with suspected EFB, point-of-care ultrasound may identify those with impaction. Suggestive findings include cervical esophageal dilatation and persistent intraluminal air-fluid levels after swallowing. EUS is a rapid, convenient test with the potential to expedite definitive management while decreasing cost and radiation exposure in this patient population.

RESUMO

BACKGROUND: Despite obesity's relevance and impact, curricula addressing obesity are underrepresented in clinical medical education. A novel pilot program to begin teaching medical students about care of the obese patient was developed and student attitudes toward obesity and bariatric surgery were assessed. METHODS: The authors paired third-year students with obese patients undergoing bariatric surgery. Students established a longitudinal patient relationship, received faculty mentorship, and kept a reflections journal. An attitude assessment survey was administered before and after third year. Reflections were analyzed for common themes. RESULTS: Baseline student responses differed from those previously reported for practicing physicians on many survey statements, including more strongly agreeing with the relationship between obesity and serious medical conditions (P < .001), the need to educate patients about obesity risks (P < .001), and willingness to recommend bariatric surgery evaluation (P = .004). These differences were maintained after clinical clerkships. Reflection themes included recognition of obesity stereotypes, improved estimation of body mass index, and awareness of physicians' attitudes about obesity. CONCLUSION: Development and assessment of a novel pilot program to teach third-year medical students about obesity and bariatric surgery suggests a potential impact on student attitudes and understanding of obesity and obesity surgery. Students today may have different attitudes toward obesity than those reflected in prior data for physicians in practice, and programs such as this may help maintain positive attitudes.

RESUMO

OBJETIVO: Valorar la carga de enfermedad e identificar las características epidemiológicas de la diarrea causada por rotavirus en América Latina. MÉTODOS: Realizamos una revisión de la literatura que abarcaba los estudios de niños menores de 5 años que fueron hospitalizados o atendidos como pacientes ambulatorios a causa de la diarrea, y en los cuales se buscó al rotavirus como agente etiológico de la diarrea. Nuestro trabajo de revisión incluye los estudios publicados desde el año 1998 sobre pacientes ingresados y ambulatorios, que incluyeron a 100 niños o más, y que informaron sobre actividades de vigilancia que se prolongaron durante al menos 12 meses consecutivos. RESULTADOS: Un total de 18 estudios de pacientes ingresados y 10 estudios de pacientes ambulatorios satisficieron los criterios de inclusión de nuestro trabajo de revisión. Se detectó el rotavirus en el 31% (mediano) de los pacientes ingresados (intervalo del 16% al 52%) y en el 30.5% de los pacientes ambulatorios (intervalo del 4% al 42%). La tasa mediana de detección fue mayor en los estudios que emplearon un ensayo de encimoinmunoanálisis (ELISA) (pacientes ingresados: 38%, pacientes ambulatorios: 33%) frente a otros métodos de detección menos sensibles. La distribución de la enfermedad rotavírica según la edad difería entre países, aunque la proporción de niños hospitalizados durante el primer año de vida fue del 65% al 85%. En la mayoría de los países se produjeron ingresos hospitalarios por rotavirus durante todo el año, y el rotavirus normalmente mostraba un máximo estacional en el invierno tanto en las zonas de clima tropical como en aquellas de clima templado. CONCLUSIONES: La importante carga de enfermedad que se atribuye al rotavirus en América Latina sugiere que las vacunas que están siendo ensayadas en la actualidad podrían tener un impacto considerable en la prevención de las hospitalizaciones, consultas a los centros de salud, y muertes. La distribución de la enfermedad entre los pacientes más jóvenes subraya la importancia de la inmunización precoz en el éxito de los programas de vacunación. Los datos sugieren que en el futuro, los programas de vigilancia para detectar la diarrea causada por rotavirus en América Latina deberían usar un protocolo normalizado de vigilancia con ELISA para la detección del virus. Los datos provenientes de estudios de vigilancia serán de importancia fundamental para el seguimiento del impacto de la introducción de vacunas en el futuro.
