Item Appendicular Lymphoid Hyperplasia in the Differential Diagnosis of Acute Appendicitis: Sonographic Findings(2020) Whittle, Carolina; Pérez, Lizbet; Cortes, Marcela; Switt, Margarita; Aguirre, Javiera; Castro, AlexObjectives: To describe sonographic findings of appendicular lymphoid hyperplasia (ALH) and to report demographic data of patients with ALH operated for acute appendicitis (AA). Materials and Methods: In a retrospective study, 694 biopsies of consecutive AA surgeries with previous ultrasonography (US) were reviewed, after selecting the ALH cases. Results: Twenty-five ALH cases were proved histologically (3.8% of appendectomies). The mean age was 13 years, with 84% under 20 years. US findings showed increased appendiceal diameter (average 7 mm) (82%), hypoechogenic pseudonodular mucosal thickening (50%), concentric parietal thickening (13%), and periappendiceal inflammatory changes (18%). In four cases, a normal appendix was noted on US, with two associated with intestinal intussusceptions. Conclusion: ALH is a benign entity most frequent in children that can predispose to AA. Both pathologies can increase the appendiceal diameter. In the pediatric group, ALH could be considered when hypoechogenic pseudonodular appendicular mucosal thickening in the absence of periappendiceal inflammatory changes occurs.Item Barreras y facilitadores del programa de salud intercultural percibidos por la asociación indígena Mapuche Taiñ Adkimn y los profesionalse de la salud de los CESFAM El Roble y Santo Tomás(Universidad del Desarrollo.

Sin embargo, se describe la asociación con malformaciones cardiacas y herniaciones del miocardio con el subsiguiente riesgo de muerte súbita. La radiografía de tórax es un pilar fundamental para la sospecha diagnóstica. Presentamos un caso clínico de una paciente de 11 años que consulta por dolor torácico y disnea, que frente a los hallazgos típicos en radiografía de tórax se sospecha agenesia pericárdica, posteriormente confirmada con TC y RM.Item Subungual Exostosis: High-Resolution Ultrasound Findings(2019) Whittle, Carolina; Aguirre, Javiera; Catalán, Verónica; Fajre, XimenaSubungual exostosis is a rare solitary benign osteocartilaginous tumor that arises from the tuft of the distal phalanx beneath the nail. Because of its multiple clinical presentations, it is commonly underdiagnosed, resulting in delayed diagnosis and inadequate treatment. This report provides results from a 6-year retrospective study. All patients with a sonographic diagnosis of subungual exostosis confirmed surgically were selected. The data came from a series of 19 patient cases. Only 15.7% were clinically suspected. The median age was 21 years, and 63% were females. The sonographic findings were nail dystrophy, distal onycholysis, abnormal nail incurvation, subungual space enlargement, and the presence of hyperechogenic subungual image with acoustic shadowing that continued until the phalanx surface. Sonography provides an excellent diagnostic method for subungual exostosis, with findings that are pathognomonic.
