Infection of an urachal cyst during etanercept therapy in juvenile idiopathic arthritis.

Etanercept, a tumor necrosis factor (TNF) receptor alpha antagonist is licensed for the treatment in patients affected by polyarticular juvenile idiopathic arthritis, who do not tolerate or had an inadequate response to methotrexate. Infections related to immunosuppression by etanercept are of major concern. We report on a 17-year-old boy with enthesitis-related arthritis who developed a major infection of an urachal cyst 18 months after initiation of etanercept therapy, which required surgery.

A dangerous liaison--pheochromocytoma in patients with malignant disease.

Background: Adrenal masses in patients with known malignancy may be interpreted as metastasized disease, although a significant proportion of these tumors are of adrenal origin. Despite improved imaging techniques, it remains difficult to distinguish an adrenal metastasis from a pheochromocytoma or a lipid-poor adrenocortical adenoma.

Patients And Methods: We report a case series of four patients with established or suspected malignant disease (melanoma, transitional cell carcinoma and prostate carcinoma, thyroid carcinoma, colorectal carcinoma) harboring an adrenal mass.

Continent cutaneous urinary diversion: long-term follow-up of more than 800 patients with ileocecal reservoirs.

We report the clinical outcome of more than 800 patients, who underwent continent cutaneous urinary diversion with an ileocecal reservoir (Mainz-pouch I) in two urological tertiary referral centers at a mean follow-up of 7.6 years. Complications related to the continence mechanism (intussuscepted ileal nipple vs.
