This file consists of a lecture on hypocalcemia. It is intended for use as reference material by physicians and other health care professionals. I am an endocrinologist at the University of California Los Angeles and this material is used to train internal medicine residents rotating through endocrinology. Each file is based on current medical literature and describes signs & symptoms, epidemiology, differential diagnosis and management of hypocalcemia. The treatment section also describes the various forms of calcium replacement. The file is in the DOC format and thus requires installation on the handheld computer of a program which can display files in the DOC format (such as AportisDoc, SmartDoc, TealDoc, CSpotRun, etc.). The trial version contains most of the lecture. The full version also contains a section on treatment of hypocalcemia. The only way to obtain the full version is at Handango. Those who purchase the full version will be entitled to unlimited updates on demand by emailing the author.
