Background: The pain of the right iliac fossa in the pediatric patient is not always caused by acute appendicitis; there are benign clinical entities up to surgical diseases, called "appendicitis simulators". Objective: To determine the usefulness of ultrasound in acute abdominal pain of the right iliac fossa, compared with the diagnosis at discharge, in pediatric patients of the José Carrasco Arteaga Hospital, Cuenca 2017. Methodology: his is a descriptive study and diagnostic test in pediatric patients with acute abdominal pain in the right iliac fossa, who underwent an abdominal ultrasound, from January to December 2017. The information was taken through a data collection form and statistical software for the descriptive study. Analysis using simple frequency and percentage tables. For the diagnostic test, sensitivity and specificity were obtained, positive and negative predictive value, positive and negative likelihood ratio. RESULTS: 301 patients were evaluated, 195 with pathology, 57.8% were between 10-15 years old, 50.5% are female. The following pathologies were observed; Mesenteric adenitis (33.6%), acute appendicitis (19.3%), gastroenteritis (5.6%), intestinal invasion (3.3%), hemorrhagic cyst and ovarian torsion (<2%). The ultrasound showed sensitivity 99.42, specificity 81.40. CONCLUSIONS: Abdominal ultrasound is an excellent tool to assess acute appendicitis and pathologies that mimic the pain of this disease. Although the sensitivity and specificity is varied in the literature, it should be the first modality of imaging in the pediatric patient.
Utilidad de la ultrasonografía en el abordaje del nódulo tiroideo

Introduction: Nodular thyroid disease is a common clinical entity, with a predominance of benign cases. The importance of the study is rule out malignancy. The anamnesis and physical examination generally have low predictive power for diagnosing malignancy. Thyroid ultrasonography is the most sensitive imaging technique to detect and characterize thyroid lesions. However, none of its characteristics is enough to differentiate between benignity and malignancy; The System Thyroid Reporting and Data Images (TIRADS) bring these features to differentiate and transmit evenly, the findings and the risk of malignancy. The biopsy fine needle aspiration is the most accurate, cost effective and safe method in the study of thyroid nodules. Objective: To analyze the ultrasonography features, correlating with the presence of malignancy, evaluating the reproducibility of the TIRADS classification. Conclusion: Given the variability of ultrasonography criteria, it is important to adopt the TIRADS, simple and practical application to optimize the management of thyroid nodule
