Consequences of Different Corticosteroids on Serum Potassium and Prostate-Specific Antigen in Patients Receiving Abiraterone for Castration-Resistant Prostate Cancer: A Retrospective Observational Study.

Background: Abiraterone acetate is an androgen synthesis inhibitor approved for the treatment of castration-resistant prostate cancer (CRPC). Although co-administration of either prednisone or prednisolone at 10 mg/d has been recommended to reduce the risk of abiraterone-induced hyperaldosteronism (notably hypokalemia) and to give adjunctive pain relief effects, whether these glucocorticoids can be substituted by dexamethasone remains unknown.

Methods: We performed a retrospective review of medical records of patients who were given abiraterone for the treatment of CRPC with either prednisolone (ABI/PSL) 10 mg/d or dexamethasone (ABI/DEX) 0.

Influence of proton pump inhibitors and histamine H receptor antagonists on serum phosphorus level control by calcium carbonate in patients undergoing hemodialysis: a retrospective medical chart review.

Background: Hyperphosphatemia is one of the common complications in patients undergoing hemodialysis. Although calcium carbonate (CaC) is often used to control serum inorganic phosphorus level in dialysis patients, co-administration of gastric acid reducers (ARs) may interfere with the phosphate binding effect of CaC. We performed a retrospective medical chart review to study whether ARs attenuate the hypophosphatemic effect of CaC in patients undergoing hemodialysis.

[Sensory nerve anesthesia with 4% liposomal lidocaine cream in healthy subjects by use of the neuroselective current perception threshold].

Background: ELA-Max, an external liposomal preparation of lidocaine (4%) available without prescription in United States, has a recommended application time of 15 to 45 min without occlusive dressing, and the side effect has been reported to be rare. To investigate external anesthetic preparations to reduce neuropathic pain, we evaluated sensory nerve anesthesia by ELA-Max in comparison with placebo and other lidocaine topical preparations by double blind method.

Methods: We measured the neuroselective current perception threshold (N-CPT) 30 min after the application of ELA-Max on 30 healthy Japanese volunteers.
