Primitive neuroectodermal tumor with kidney involvement: a case report.

Primitive neuroectodermal tumor (PNET) is usually an aggressive, rapidly progressing and metastasizing tumor. Occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. We present a metastatic PNET arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach.

Helicobacter pylori eradication in renal recipient: triple or quadruple therapy?

Although triple (omeprazole, amoxicillin, and metronidazole) and quadruple (omeprazole, tetracycline, metronidazole, and bismuth subcitrate) therapeutic regimens for H. pylori eradication has been studied much in the general population, there is a lack of data in renal transplanted patients. So, this study aimed at comparing regimens in these patients who were considered being immunocompromised.

Endoscopic resection of large colonic lipomas assisted by a prototype single-use endoloop device.

Giant colonic lipoma (GCL) is an uncommon finding at endoscopy which may lead to iron deficiency anemia (IDA) with or without macroscopic ulceration. The choice of therapeutic procedure to treat symptomatic GCLs has been controversial.
