Enfermedad de Ménétrier, reporte de caso (con video) / Menetrier disease: Case report with video

Resumen La enfermedad de Ménétrier, también conocida como gastritis hipertrófica gigante o gastropatía hipertrófica hipoproteinémica, es una entidad poco frecuente, caracterizada por una gastroenteropatía perdedora de proteínas, hipoclorhidria y engrosamiento de los pliegues mucosos del fondo y el cuerpo gástrico; es causante de un grupo clásico de síntomas que incluyen náuseas, vómitos, dolor abdominal y edema periférico; se asocia con un mayor riesgo de cáncer gástrico, sin embargo, su fisiopatología aún no está del todo esclarecida y su diagnóstico, clínico y endoscópico, puede llegar a ser difícil de establecer, por lo que se describe un caso clínico y se presenta una revisión sucinta de la literatura.

Abstract Menetrier disease (also known as giant hypertrophic gastritis or hypoproteinemic hypertrophic gastropathy) is a rare entity characterized by protein losing enteropathy, hypochlorhydria and thickening of the mucosal folds of the fundus and the gastric corpus. Its constellation of classic symptoms includes nausea, vomiting, abdominal pain and peripheral edema, and it is associated with increased risk of gastric cancer. Nevertheless, its pathophysiology is not yet fully understood and clinical and endoscopic diagnosis can be difficult to establish. This article describes a clinical case and provides a brief review of the literature.

The Relationship between Ciliary Beat Frequency and Maxillary Sinus Mucosal Hypertrophy on Computed Tomography in Patients with Chronic Sinusitis / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: This study was designed to investigate the relationship between the sinus mucosal hypertrophy and ciliary beat frequency (CBF) in patients with chronic sinusitis in vitro. MATERIALS AND METHODS: In 14 patients with chronic sinusitis, mucosal samples were obtained from the superior, inferior, and lateral walls of the maxillary sinus. Using a video-computerized analysis technique, we measured two parameters for ciliary activity at five different sites selected randomly from each sample=the ciliated area (%) showing CBF equal to or higher than 10 Hz (A10) and the weighted frequency (Fw). Mucosal hypertrophy of the maxillary sinus was calculated using a computer program on CT scans. RESULTS: A(>or=10) and Fw were 91% and 11.3 Hz in control group, respectively, whereas they were 47% and 9.1 Hz in chronic sinusitis group, respectively (p=0.03). There was a significant inverse correlation between A(>or=10) or Fw and mucosal hypertrophy of the maxillary sinus (p=0.001). CONCLUSION: The results of this study suggest that the severity of mucosal hypertrophy on CT scan may correlate with the ciliary activity.
