RESUMEN

Osler-Weber-Rendu, also known as Hereditary Hemorrhagic Telangiectasia, is an autosomal dominant disease with phenotypic manifestations that include pulmonary, cerebrospinal, hepatic, and other visceral arteriovenous malformations (AVMs). Pulmonary AVMs can result in hypoxemia, hemoptysis, or stroke due to paradoxical embolism. The mainstay of treatment is transcatheter embolization. Central nervous system and abdominal visceral AVMs contribute to morbidity of the disease. Radiologists should be familiar with the imaging manifestations and treatment algorithm of AVMs in Osler-Weber-Rendu to effectively guide patient care.

RESUMEN

PURPOSE: We investigated the impact of modality-specific volumes and other potential stressors on burnout and career-choice satisfaction. MATERIALS AND METHODS: An anonymous survey of 36 questions was sent by email to all 875 faculty members of the STR. These included 11 multiple-choice questions, 23 Likert questions, and 2 free-text questions. The Maslach Burnout Index was used to assess the prevalence of the 3 components of burnout (emotional exhaustion, depersonalization, and low professional accomplishment), and we assessed variations among the potential sources of stress with respect to the respondent sex, career stage, and practice setting. Respondents were asked to estimate daily work volume as if interpreting only chest radiographs (CXRs) or only chest/cardiac computed tomography (CT). Statistical analysis was performed using Excel (Microsoft), open-source statistical computing package pandas and SciPy for Python, and Jupyter Notebook, an open-source interactive computing platform. RESULTS: Although financial concerns (49.3%), lack of input into decisions (48.6%), and inadequate staffing (45.2%) were additional stressors, the major sources were work-life balance (67.4%) and workload (66.8%), which were more frequently cited by women than men (78.9% vs. 60.8%, P=0.001). Emotional exhaustion and depersonalization were related to higher CXR volumes. Although 83.2% were satisfied being a diagnostic radiologist, 18.8% had thought of leaving medicine. More than half of all radiologists interpreted ≥150 CXRs daily (51.1% vs. 53.6%); more in private practice read ≥200 CXRs (23.2% vs. 14.7%). Of the academic radiologists, 80.2% interpreted 21 to 49 CTs; twice as many in private practice read ≥50 CTs (25.5% vs. 12.7%). CONCLUSIONS: The contributing factors to cardiothoracic radiologist burnout vary by sex, career stage, and practice setting. Several stressors, especially work-life balance, were associated with higher burnout prevalence. Most respondents expressed career-choice satisfaction. Defining threshold work volumes associated with higher rates of burnout is an important first step in defining burnout prevention guardrails.

RESUMEN

PURPOSE: Burnout is a psychological syndrome in response to chronic occupational stressors. The prevalence of burnout among medical professionals has been increasing, and recent studies have shown that radiologists are among those affected. We investigated the prevalence of burnout and assessed associated factors among cardiothoracic radiologists. MATERIALS AND METHODS: Society of Thoracic Radiology members were invited to complete an anonymous cross-sectional survey that included an adapted Maslach Burnout Inventory and questions about demographics, work place characteristics, and stressors. RESULTS: The survey response rate was 33.1% (290/874). Per-item response rate ranged from 94% to 100% with a median of 99%. The prevalence of emotional exhaustion was 66.8% (186/283), depersonalization was 79% (223/283), and low personal accomplishment was 23% (65/280). There were no statistically significant differences between academic and private practice. There was a trend toward worse burnout in women, but this was not statistically significant. Being in early career (0 to 10 y since fellowship) was associated with low personal accomplishment [odds ratio (OR): 2.07, 95% confidence interval (CI): 1.08-3.99]. Those working fewer than 51 hours per week were significantly less likely to report emotional exhaustion (OR: 0.55, 95% CI: 0.33-0.90). The odds of emotional exhaustion for those producing fewer than 7500 work relative value units per year were approximately half of those exceeding that number (OR: 0.46, 95% CI: 0.22-0.95). CONCLUSIONS: The prevalence of burnout among cardiothoracic radiologists is comparable to that reported for radiologists in other subspecialties such as musculoskeletal and interventional radiology. High work relative value unit productivity and longer work hours are associated with higher prevalence of burnout.

RESUMEN

The following fictional case is intended as a learning tool within the Pathology Competencies for Medical Education (PCME), a set of national standards for teaching pathology. These are divided into three basic competencies: Disease Mechanisms and Processes, Organ System Pathology, and Diagnostic Medicine and Therapeutic Pathology. For additional information, and a full list of learning objectives for all three competencies, see http://journals.sagepub.com/doi/10.1177/2374289517715040.1.

RESUMEN

Pulmonary adenofibroma (PAF) is a rare neoplasm that may be related to solitary fibrous tumor (SFT). A subset of PAFs harbor the NAB2-STAT6 fusion that is typical of SFT, but a significant proportion do not. Their distinction is clinically important as SFTs can potentially have an aggressive clinical course, while there has been no report of a PAF behaving in a malignant fashion. We report a case of a 60-year-old male who developed a SFT and PAF in the same lung. The SFT harbored a NAB2-STAT6 fusion, while the PAF did not have any identifiable fusion. This case represents the first instance of a single patient with both of these tumors occurring simultaneously in the same lung.

RESUMEN

PURPOSE: To determine whether radiation dose to patients can be reduced for clinical thoracic CT scans without loss of diagnostic information. MATERIALS AND METHODS: One hundred consecutive patients having clinical CT examinations of the thorax were included. The patients were divided into 4 groups, and the mAs setting determined from the patient's weight as follows (max. 300 and min. 100 mAs): group 1: mAs = weight in lbs. rounded to the next multiple of 10, plus 30 (mAs = wtR + 30); group 2: mAs = weight rounded to the next multiple of 10 (mAs = wtR); group 3: mAs = weight rounded to the next multiple of 10, minus 20 (mAs = wtR - 20); group 4: mAs = weight rounded to the next multiple of 10, minus 30 (mAs = wtR - 30). The neck, mediastinum, lungs, and upper abdomen were assessed for quality on a 4 point scale. RESULTS: Only at the lowest mAs levels did we see some degradation of image quality in the lower neck with an increase in streak artifacts. The other body regions all showed good or excellent image quality. CONCLUSIONS: Radiation dosage can be reduced by more than half without loss of diagnostic quality, using this simple formula: mAs = weight in lbs. rounded to the next multiple of 10 minus 30 (mAs = wtR - 30).

RESUMEN

The pericardium plays an important role in optimizing cardiac motion and chamber pressures and serves as a barrier to pathology. In addition to pericardial anatomy and function, this review article covers a variety of pericardial conditions, with mention of potential pitfalls encountered during interpretation of diagnostic imaging. Normal and abnormal appearance of pericardium on CT and MR imaging is emphasized, including dynamic imaging correlates of pericardial pathophysiology.
