Pancreatitis in the setting of the metabolic syndrome

There is paucity of literature on the relation of obesity with recurrent and chronic pancreatitis. We recorded the clinical details and the outcome of five patients with recurrent pancreatitis who had components of the metabolic syndrome. Their age ranged from 8 to 20 years. All five patients had acanthosis nigricans. Body mass index (BMI) could not be evaluated as these patients lost weight following episodes of pancreatitis. Three patients had two or more first-degree relatives who had diabetes mellitus. Only one patient had severe necrotizing pancreatitis. Coexisting liver disease was seen in two patients. Elevated serum cholesterol levels and moderately elevated serum triglycerides along with elevated serum amylase levels observed in these patients suggest possibility of a different mechanism from that of hypertriglyceridemia-related pancreatitis. Evaluation of pancreatic steatosis should be considered in patients with pancreatitis in the setting of metabolic syndrome.

Validity and reliability of nerve and muscle ultrasound

Introduction: Nerve and muscle ultrasound has been studied in several conditions, but validity and reliability have not been assessed systematically. Methods: Nerve cross‐sectional area and muscle thickness were measured ultrasonographically at several sites in 4 cadavers, which were then dissected, and actual measurements were obtained. To assess intrarater and interrater reliability, between 3 and 5 ultrasonographers, with varying experience levels, made repeated measurements on healthy volunteers. Results: Correlation coefficients for nerve and muscle validity were >0.968 (P < 0.001), and for intrarater reliability were >0.901 (P < 0.001) for still and real‐time images. Correlation coefficients for interrater reliability were more varied, but for still images they were all significant at the P < 0.001 (0.542–0.998) level, and for real‐time images they were significant at the P < 0.05 level for half the sites (0.243–0.981). Conclusion: Overall, nerve and muscle ultrasound is a valid and reliable diagnostic imaging technique. Muscle Nerve, 2013     

Using Artificial Intelligence to Improve the Quality and Safety of Radiation Therapy

Within artificial intelligence, machine learning (ML) efforts in radiation oncology have augmented the transition from generalized to personalized treatment delivery. Although their impact on quality and safety of radiation therapy has been limited, they are increasingly being used throughout radiation therapy workflows. Various data-driven approaches have been used for outcome prediction, CT simulation, clinical decision support, knowledge-based planning, adaptive radiation therapy, plan validation, machine quality assurance, and process quality assurance; however, there are many challenges that need to be addressed with the creation and usage of ML algorithms as well as the interpretation and dissemination of findings. In this review, the authors present current applications of ML in radiation oncology quality and safety initiatives, discuss challenges faced by the radiation oncology community, and suggest future directions.
