Yi-Cheng Zhao: a founder of neurosurgery in China.
Yi-Cheng Zhao was trained in neurosurgery at the Montreal Neurological Institute by Wilder Penfield in 1938. This article presents Zhao's great contributions to the development of neurosurgery in China. He set up the first independent neurosurgical departments in Tianjin (1952) and in Beijing (1954). ⋯ It plays an important role in the development of Chinese neurosurgery. Zhao devoted nearly 40 years to neurosurgery and died in 1974. The chinese Neurosurgical Association has honored Zhao as "a founder of neurosurgery in China."

The management of malignant posttraumatic cerebral edema remains a frustrating endeavor for the neurosurgeon and the intensivist. Mortality and morbidity rates remain high despite refinements in medical and pharmacological means of controlling elevated intracranial pressure; therefore, a comparison of medical management versus decompressive craniectomy in the management of malignant posttraumatic cerebral edema was undertaken. ⋯ Decompressive bifrontal craniectomy provides a statistical advantage over medical treatment of intractable posttraumatic cerebral hypertension and should be considered in the management of malignant posttraumatic cerebral swelling. If the operation can be accomplished before the ICP value exceeds 40 torr for a sustained period and within 48 hours of the time of injury, the potential to influence outcome is greatest.

We report a case of head injury, in which a hyperosmolar state evolved during the course of treatment, complicated by severe rhabdomyolysis and acute renal failure, which subsequently resulted in a good recovery after intensive supportive treatment. To our knowledge, such high levels of creatine kinase in a patient with head injury and rhabdomyolysis have not been reported. ⋯ We postulate that the hyperosmolar state of the patient was the major cause of his severe rhabdomyolysis. Associated hypokalemia and hypophosphatemia are also predisposed to rhabdomyolysis. The most serious complication in rhabdomyolysis is acute renal failure, but most patients who receive supportive treatment and can survive despite the complications can expect to have normal renal function restored.
