Objective: The collecting duct carcinoma (Bellini's carcinoma) is an unfrequent lesion; its macro and microscopic characteristics can help diagnosis. 65-year-old Colombian woman presenting left-flank and hypochondrio stub-type episodic pain associated with hematuria, nausea and weight loss.
Results: The diagnosis was of collecting duct carcinoma.
Conclusions: The clinical characteristics, macrocospic features, histology and immunohistochemistry are analyzed; we also perform a bibliography review.

Epithelial sodium channel (ENaC), located in the collecting duct principal cells of the kidney, is responsible for the reabsorption of sodium and plays a critical role in the regulation of extracellular fluid volume and consequently blood pressure. The G protein-coupled bile acid receptor (TGR5) is a membrane receptor mediating effects of bile acid and is implicated in kidney diseases. The current study aims to investigate whether TGR5 activation in the kidney regulated ENaC expression and potential mechanism.

Vasopressin (VP) activates protein kinase A (PKA), resulting in phosphorylation events and membrane accumulation of aquaporin-2 (AQP2). Epidermal growth factor receptor (EGFR) inhibition with erlotinib also induces AQP2 membrane trafficking with a phosphorylation pattern similar to VP, but without increasing PKA activity. Here, we identify the ribosomal s6 kinase (RSK) as a major mediator phosphorylating AQP2 in this novel, erlotinib-induced pathway.

Background: Pancreatic acinar cell carcinoma (PACC) is a rare subtype of pancreatic cancer and the clinicopathological behavior of PACC is not yet fully understood. PACC rarely invades the main pancreatic duct (MPD), which causes intraductal growth. Thus, herein, we have reported a rare case of PACC that invaded the MPD and disseminated to the branches of the pancreatic duct (BDs) without exhibiting any continuity with the main tumor.

Background: We performed a retrospective comparative study to clarify the optimal gallbladder drainage method prior to elective cholecystectomy.
Methods: We collected data from the Diagnosis Procedure Combination database about cholecystitis patients who underwent gallbladder drainage prior to cholecystectomy in a subsequent hospitalization between April 2014 and March 2020. We divided the study population into two groups: an endoscopic gallbladder stenting (EGBS) group and a percutaneous transhepatic gallbladder drainage (PTGBD) group.
