RESUMO
PURPOSE: Variation in protocols for axillary sentinel lymph node (SLN) mapping exists. We strive to evaluate the effectiveness of reduction in number of injections on reducing procedural pain, while maintaining nodal detection. METHODS: Over 7 years, the number of periareolar injections performed was reduced stepwise from 4 to 1. This was analyzed for SLN detection and patients' subjective perceived pain. RESULTS: 828 patients with invasive breast cancer who underwent SLN mapping were included. Laterality of breast injection site included 326 (39.4%) in the right breast, 354 (42.8%) in the left breast and 148 (17.9%) in bilateral breasts. In patients who had 4 injection sites in a unilateral breast (n = 143), the reported pain score was 4.3 ± 2.4. Patients with 3 injections (n = 163), 2 injections (n = 163) and 1 injection (n = 211) in a breast reported pain scores of 3.4 ± 2.4, 3.2 ± 2.2, and 2.9 ± 2.6, respectively. In patients who had bilateral sentinel node procedures, those with 4 injections in each breast for a total of 8 injections (n = 37) reported a pain score of 5.7 ± 2.4. Patients with 3 (n = 51), 2 (n = 31) and 1 (n = 39) injection(s) in each breast reported perceived pain of 4.8 ± 2.8, 3.7 ± 2.7 and 3.5 ± 1.9, respectively. Incremental decreased pain scores were achieved with decreasing number of injections (p < 0.001). Nodal detection was maintained. CONCLUSION: A single periareolar subdermal injection site reduces periprocedural pain while maintaining nodal detection.

OBJECTIVE: It was observed that malignancy had been found on follow-up in patients with PET-negative solid solitary pulmonary nodules (SPN). A retrospective analysis was performed to observe the natural history and malignant potential of these lesions, which, in routine practice, are presumed to be inactive. MATERIALS AND METHODS: Patients with an incidentally-discovered solid solitary pulmonary nodule who then had a negative follow-up PET/CT from 2005 to 2015 were identified using a text-based search methodology. These patients' charts were mined to determine the rate of development of subsequent malignancy from these index nodules. RESULTS: Of the patients with initially PET-negative solitary pulmonary nodule (nâ¯=â¯62, 43.5% women, mean age 65), 44 had clinical follow-up of the index lesion. 8 (7 pathology-proven) subsequent malignancies were identified with a mean time to diagnosis of 37.6 (±31.3) months. There were no statistically significant predictors of subsequent development of cancer (including age, gender, and smoking status). CONCLUSION: Upon follow up, 18.2% of the initially queried solid PET-negative nodules developed subsequent malignancy at an average time of 37.6 months, suggesting the continued need for follow-up of these initially PET-negative nodules beyond the 2 years currently suggested in popular guidelines. Importantly, these findings also remind radiologists that a negative PET/CT is not a surrogate for tissue diagnosis in the case of non-FDG avid SPN.

Recreational drug use is increasing worldwide, with emergency room visits and total deaths from drug overdose rising in recent years. Complications from prescription and recreational drug use may result from the biochemical effects of the drugs themselves, impurities mixed with substances, or from causes related to the method of drug administration. The presentation of drug overdose may be complex due to multisubstance abuse, including cigarette smoking and alcoholism, and can impact any organ system. Patients may present without history, and radiologists may be the first clinicians to suggest the diagnosis. We aim to explore the cardiothoracic manifestations of drug abuse and their multimodality imaging manifestations.

PURPOSE: To identify preferences of patients and referring physicians for direct patient communication and notification of radiologic study results. METHODS: An anonymous survey was conducted of patients undergoing outpatient radiologic imaging studies and their referring physicians. The voluntary surveys elicited responses regarding preferences on a 5-point Likert scale (Strongly disagree, disagree, neutral, agree and strongly agree), as well as indicated by responding yes or no to specific questions. RESULTS: 368 patients completed the survey. 81.5% of patient responders preferred all results communicated from the radiologist within the same day. 65.9% of patients preferred same day results if normal vs 65.8% if abnormal. 34.5% preferred to wait and review normal results with the referring physician. 41.5% preferred to wait and review abnormal results with the referring physician. It was found that patients were more likely to strongly agree with waiting to review results with the referring physician if the results were abnormal, as opposed to normal (18.5% vs 11.9%, respectively; P < 0.014). 64% of physicians did not want results reviewed with their patients; 87.6% did not want a report sent to the patient by the radiologist, even after report was sent to their office. 66.4% of patients surveyed indicated that waiting for imaging results gives them anxiety. CONCLUSIONS: 58-82% of patients preferred same day radiologist communication of their results while 55-87.6% of physicians did not prefer same day radiologist communication of results directly with their patients. 66.4% of patients surveyed indicated that waiting for imaging results gives them anxiety.
