Retrieval of Radiology Reports Citing Critical Findings with Disease-Specific Customization
Background: Communication of critical results from diagnostic procedures between caregivers is a Joint Commission national patient safety goal. Evaluating critical result communication often requires manual analysis of voluminous data, especially when reviewing unstructured textual results of radiologic findings. Information retrieval (IR) tools can facilitate this process by enabling automated retrieval of radiology reports that cite critical imaging findings. However, IR tools that have been developed for one disease or imaging modality often need substantial reconfiguration before they can be utilized for another disease entity. Purpose: This paper: 1) describes the process of customizing two Natural Language Processing (NLP) and Information Retrieval/Extraction applications – an open-source toolkit, A Nearly New Information Extraction system (ANNIE); and an application developed in-house, Information for Searching Content with an Ontology-Utilizing Toolkit (iSCOUT) – to illustrate the varying levels of customization required for different disease entities and; 2) evaluates each application’s performance in identifying and retrieving radiology reports citing critical imaging findings for three distinct diseases, pulmonary nodule, pneumothorax, and pulmonary embolus. Results: Both applications can be utilized for retrieval. iSCOUT and ANNIE had precision values between 0.90-0.98 and recall values between 0.79 and 0.94. ANNIE had consistently higher precision but required more customization. Conclusion: Understanding the customizations involved in utilizing NLP applications for various diseases will enable users to select the most suitable tool for specific tasks

Linfoma T subcutâneo do tipo paniculite: relato de um caso acometendo paciente pediátrico Subcutaneous panniculitic T cell lymphoma: a case report affecting a child
Os autores relatam um caso de linfoma T subcutâneo do tipo paniculite em uma paciente feminina de 3 anos, apresentando havia um mês múltiplos nódulos subcutâneos, indolores, disseminados no abdome, região peitoral e cervical. Ao exame histopatológico, evidenciou-se um linfoma T infiltrando tecido adiposo subcutâneo. Os linfomas T subcutâneos representam uma entidade clinicopatológica distinta, sendo raro o acometimento pediátrico.<br>We report a case of lypotrophic lymphoma affecting a 3-year-old child with 1-month history of nontender subcutaneous nodules disseminated throughout the abdomen, chest and cervical region. Histological examination showed a T-cell lymphoma affecting the subcutaneous tissue. Subcutaneous panniculitis-like T-cell lymphoma is an unusual cutaneous T-cell lymphoma that rarely affects pediatric patients
