RESUMO
BACKGROUND: Uncertainty exists regarding the management of antithrombotic medications in ischemic stroke and transient ischemic attack (TIA) patients around the time of colonoscopy. We sought to evaluate whether there was a difference in adverse events among patients who continued medications and those who had temporary discontinuation. METHODS: Using a hospital administrative database, electronic charts of patients with a diagnostic code for stroke or TIA and a procedural code for colonoscopy were reviewed. Information collected included baseline demographics, medical history, and antithrombotic medications. Outcome measures were stroke (ischemic and hemorrhagic), myocardial infarction, venous thromboembolism, and major systemic bleeding (i.e., requiring transfusion) up to 4 weeks after the procedure among patients who had medications continued versus temporarily discontinued. RESULTS: One hundred seventy-seven patients met inclusion criteria. Antithrombotic medication was temporarily discontinued in 42 patients and continued in 135 patients. Comparing patients who had medications held to those who had medications continued, stroke occurred in 1 (2.4%) versus 0 (0%; P = .237) patients; myocardial infarction in no patients in either group; venous thromboembolism in 0 (0%) versus 1 (0.7%; P > .99) patients; and major system bleeding in 2 (4.8%) versus 4 (3.0%; P = .628) patients. CONCLUSIONS: In this retrospective analysis, there was no significant difference in the occurrence of stroke, myocardial infarction, venous thromboembolism, and major bleeding between patients who had medications continued around the time of colonoscopy versus those who had temporary discontinuation. A prospective, randomized controlled study is warranted to further elucidate this issue.

A 30-year-old nulligravid woman with a history of polycystic ovarian syndrome presented for evaluation of left adnexal mass. The patient was referred to the gynecologic oncology clinic after endorsing signs of abdominal pain for a month and the pelvis ultrasound demonstrated hypoechoic solid mass in the left ovary. Magnetic resonance imaging with T1- and T2-weighted images demonstrated progressive centripetal "filling-in" of the mass suggesting a unique variation of malignant ovarian mass, similar to what is seen in hepatic hemangioma. Upon resection of the ovarian mass, pathology reported that the mass was filled with numerous small blood vessels with single later of endothelial cells confirming the diagnosis of ovarian hemangioma, capillary-type-a rare finding.
RESUMO
INTRODUCTION OF HYPOTHESIS: Little information is available regarding the imaging characteristics that assist in differentiating responders from non-responders. We hypothesized that patients with higher pretreatment tumor volume (PTV) would have lower response rates and shorter overall survival (OS). METHODS: Data from patients who received at least one dose of program death-1 (PD-1) inhibitors before August 31, 2016 were captured from our institution's pharmacy database. The primary objective was to determine the association of PTV with best response, evaluated utilizing RECIST v1.1 criteria. Secondary objectives were estimation of progression-free survival (PFS) and OS. PTV was measured using the Philips Intellispace Multi-Modality Tumor Tracking application. RESULTS: 116 non-small cell lung cancer (NSCLC) patients were evaluated. 66% patients had adenocarcinoma, 28% had squamous cell carcinoma and 5% had poorly differentiated NSCLC. Median PTV was 53.7 cm3 (95% CI: 13.3-107.9). Only one individual had no metastases and the remainder had M1 disease; 38% M1a, 10% M1b, 51% M1c. Most (79%) were previously treated. There were no complete responses; among those followed for at least 6 weeks, 26% had a partial response, 39% stable disease and 34% PD; 4% had no recorded response. There were no strong associations of PTV with any of the demographic or clinical characteristics. There was no association between PTV and OS (HR 1.2, P=0.26) or PFS (HR 1.1, P=0.47). Liver metastasis was associated with shorter survival (HR=2.8, P=0.05). CONCLUSION: PTV in NSCLC did not prove to be a predictor of response to PD-1 inhibitors but having liver metastasis was associated with significantly shorter survival.
