Tyramine sulfoconjugation following an oral tyramine load was determined in 30 patients suffering from migraine and 14 controls not regularly suffering from headache. Reduced tyramine sulfoconjugation was found in those patients with a history of major depressive disorder compared with controls. When the patients with a history of major depression were removed from the analysis, no differences were found between diet-sensitive and non-diet sensitive migraine patients and controls.

Review Case Reports
Pharmacologic management of bone pain in the cancer patient.
Cancer patients may experience acute or chronic pain caused by tumor infiltration of pain-sensitive structures or related to surgery, radiation, and chemotherapy. Acute bone pain, with or without associated neurologic deficits resulting from tumor metastasis to bone and contiguous neural structures (e.g., large peripheral nerve trunks or the spinal cord), is a common cause of intractable pain in cancer patients. ⋯ Less commonly, invasive therapies, such as resection of vertebral body tumor with spinal reconstruction or pituitary ablation and intraventricular opioid administration (for diffuse bone pain), are offered. In this article I discuss current approaches to the management of pain in cancer patients, emphasizing current hypotheses on the pathogenesis of bone pain and the rationale for its pharmacologic treatment.

In some forms of cerebrovascular disease, such as intracranial hemorrhage, headaches are well known as a prominent symptom and often are a valuable clue to diagnosis. There are difficulties, sometimes, in distinguishing between a small subarachnoid hemorrhage and a severe migraine headache, but these can be resolved using clinical observations, CT scan, and lumbar puncture. It seems less well known that headaches may accompany or precede cerebral thrombosis and embolism. When these headaches are recognized as a forerunner to stroke, they may allow an opportunity for preventive treatment.

An inpatient headache treatment unit provides a special environment for those patients whose headaches have failed to respond to outpatient therapy. Outpatient therapy may be precluded for a variety of treatment issues, including detoxification, initiation of copharmacy prophylactic medical therapy, and intravenous treatment for intractable chronic cluster headache and status migrainous headache. These complex medical treatments are viewed as some of the most valuable therapies by the patients and, at least in part, significantly decrease both headache indexes utilized in this survey. ⋯ Treatment failures may be due to variations in the etiology of chronic muscle contraction headache and posttraumatic headache. Denial of psychological factors in headache may also contribute to treatment failure. Habituation to analgesics and ergots may decrease patient response as compared with those not dependent.
