Review Case ReportsFatal hypernatremia from exogenous salt intake: report of a case and review of the literature.
Hypernatremia is a common electrolyte disturbance, most often caused by volume depletion. Hypernatremia due to sodium excess occurs less frequently, and fatal hypernatremia solely from ingestion of table salt is rare. We describe a 41-year-old man who had seizures and hypernatremia after ingestion of a supersaturated salt water solution intended for gargling. ⋯ The age of the patient and the initial serum sodium concentration were the most important prognostic indicators. Both very young patients and those with lesser degrees of hypernatremia had a better rate of survival than did other patients. In addition, our review illustrates the surprisingly small amount of salt that can cause severe hypernatremia and the danger of using salt or saline as an emetic.

Many neurologic disorders, such as eclampsia, pseudotumor cerebri, stroke, obstetric nerve palsies, subarachnoid hemorrhage, pituitary tumors, and choriocarcinoma, can develop in the pregnant patient. Maternal mortality from eclampsia, which ranges from 0 to 14%, can be due to intracerebral hemorrhage, pulmonary edema, disseminated intravascular coagulation, abruptio placentae, or failure of the liver or kidneys. Associated fetal mortality ranges from 10 to 28% and is directly related to decreased placental perfusion. ⋯ This malignant tumor has a high rate of cerebral metastatic lesions. In addition to these disorders that develop during pregnancy, the pregnant state can affect numerous preexisting neurologic conditions, including epilepsy, headaches, multiple sclerosis, myasthenia gravis, spinal cord injury, and brain tumors. We discuss advice for patients with such conditions who wish to become pregnant, recommendations for medical and surgical management, and surgical considerations for neurologic complications during pregnancy.
