Cystic Tumors of the Pancreas: Ultrasound, Computed Tomography, and Magnetic Resonance Imaging Features

Cystic tumors of the pancreas are a subset of rare pancreatic tumors that vary from benign to malignant. Many have specific imaging findings that allow them to be differentiated from each other. This article aims to review the histopathologic and imaging findings of the relatively common lesions (serous microcystic adenoma, mucinous cystic tumor, intraductal papillary mucinous tumor, and solid pseudopapillary tumor) and uncommon lesions (cystic endocrine tumors, cystic metastases, cystic teratomas, and lymphangiomas) in this group.     

Renal replacement therapy is an independent risk factor for mortality in critically ill patients with acute kidney injury

Introduction  

Outcome studies in patients with acute kidney injury (AKI) have focused on differences between modalities of renal replacement therapy (RRT). The outcome of conservative treatment, however, has never been compared with RRT.     

Posterior amorphous corneal dystrophy caused by a de novo deletion

We present a newborn diagnosed with posterior amorphous corneal dystrophy (PACD). PACD is a rare disorder with partial or complete posterior lamellar corneal opacification. Genetic screening showed a deletion of chromosome 12q21.33-q22 containing the identified four small leucine-rich proteoglycans (SLRP’s) associated with this particular dystrophy. Neither parents were carrier of the deletion. To our knowledge, this is the first report of a de novo mutation causing PACD.
