Despite good test performance, a CaPTHUS score ≥3 does not discard MGD definitely. Intraoperative adjuncts are still needed to further reduce the risk of missing MGD during selective parathyroidectomy.
To determine whether IV melatonin therapy improves redox status and inflammatory responses in surgical patients with severe sepsis, a unicenter, phase II double-blind, randomized, placebo-controlled trial was carried out. The study included patients with severe sepsis marked by infectious systemic inflammatory response syndrome (SIRS), associated with organ dysfunction, hypoperfusion or hypotension requiring surgical intervention. IV melatonin at a daily dose of 60 mg, which was dissolved in 500 ml of 5% dextrose serum, was continuously administered to the patients for over 30 min starting on the day of the diagnoses during a 5-day period. A total of 14 patients received a placebo treatment and 15 melatonin doses. Redox status decreased in melatonin-treated patients during the 5 days of treatment as compared to the placebo-treated patients. Procalcitonin performed better in the melatonin group, whose neutrophil to lymphocyte ratio was also significantly reduced, resulting in an improved evolution of the disease. Moreover, hospital stays decreased by 19.60% from 26.64 days for the placebo group to 21.42 days for the melatonin group. The placebo group recorded five mortalities, as
Objectives: Determine the usefulness of [18F]-fluorodeoxyglucose positron emission tomography/computed tomography ( 18 FDG-PET/CT) in the preoperative setting of colorectal cancer (CRC), assessing its impact on changes in management strategy.Methods: Retrospective study of CRC patients who underwent preoperative 18 FDG-PET/CT and CT staging scans in a single referral center. The agreement between 18 FDG-PET/CT, contrast-enhanced CT, and colonoscopy for the surgical location was compared using the κ coefficient. Maximum standardized uptake (SUV max ) value was obtained. Univariate and multivariate analyses were conducted.Results: One hundred ninety-five patients were included. 18 FDG-PET/CT improved tumor localization in 84.6% (165/195) of cases (κ value 0.798, p < 0.001), thus correcting endoscopic errors 69.7% (30/43) of the time. In patients with incomplete colonoscopies, 18 FDG-PET/CT detected synchronous tumors in 2.5% (5/195) patients, overlooked by CT staging scans. Based on extracolonic 18 FDGuptake, the second primary malignancy was diagnosed in 7(3.6%,7/195) patients and total accuracy for lymph node and distant metastasis was 66.1% and 98.4%, respectively. The treatment plan was altered in 30 (15.4%, 30/196) patients. There was a significant association between the SUV max and tumor size (odds ratio [OR] 4.254, p = 0.003) and the depth of tumor invasion (OR 1.696, p = 0.026).Conclusions: Based on its ability to aid in preoperative evaluation and definitively alter surgical treatment planning, 18 FDG-PET/CT should be further evaluated in primary CRC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
