Does choledochal cysts in children : Intrahepatic ductal dilatation indicate true intrahepatic biliary duct disease?
In this study, most intrahepatic ductal dilatations seen on preoperative imaging were thought to be caused by a distal obstruction, not true intrahepatic biliary duct disease. This study supports the hypothesis that preoperatively distinguishing between type I and type IVA CCs is not necessary; it does not affect the initial treatment. We consider that complete cyst excision with Roux-en-Y hepaticojejunostomy is safe and should be performed soon after diagnosis, irrespective of symptom severity to avoid future complications.
A very strong and significant association between ED visits or hospital admissions for asthma and SABA prescriptions was observed, which suggests that SABA prescription fills can be used as a marker for asthma morbidity. In addition, a temporal association exists between claims for ED visits or hospital admissions for asthma and SABA prescription claims when an ED visit or hospital admission precedes the SABA prescription.
