Idiopathic retroperitoneal fibrosis presenting as recurrent scrotal edema: Report of a case and review of the literature.

Primary or idiopathic retroperitoneal fibrosis, first described by Ormond in 1948, is a rare and elusive diagnosis, requiring a high level of suspicion. Patients usually present with entrapment of retroperitoneal organs, the most common being the ureters, causing hydronephrosis and acute kidney injury. Here, we present the case of a 56-year-old male presenting for recurrent and intermittent scrotal edema.

Wernicke's encephalopathy three weeks after sleeve gastrectomy.

Following bariatric surgeries for management of morbid obesity, less nutrients are absorbed, giving rise to complications due to vitamin deficiencies with frequently dramatic consequences. Neurologic complications resulting from folate, vitamin B12, and thiamine deficiencies have been estimated to occur in up to 16% of cases and present within weeks to months following bariatric surgery. Among bariatric surgeries, Roux-en-Y gastric bypass has been the most associated with such deficiencies due to both restrictive and malabsorptive components.
