Sporadic unilateral papillary renal cell carcinoma masquerading pyelonephritis: A case report.

Hidden renal cell carcinoma (RCC) is not evident during severe inflammation such as acute pyelonephritis. We presented a 62-year-old male presenting with features of obstructive pyelonephritis managed with simple nephrectomy. However, the histopathology findings suggested unilateral papillary RCC.

Development of sustained release floating drug delivery system for norfloxacin: in vitro and in vivo evaluation.

Unlabelled: Norfloxacin is a drug with an absorption window. Its oral bioavailability is 30-40% and is a case for improvement by appropriate formulation design. In our previous study, gastroretentive floating tablets for norfloxacin were developed employing three different polymers such as HPMC K4M, HPMC K100M, and xanthan gum.
