Current pain and headache reports

This article discusses the headache disorders associated with physical and sexual activity, highlighting their differences and similarities. The place of exertional and sexual headaches in the classification of the International Headache Society and in the proposed classification of Indomethacin-Responsive Headache Disorders is addressed here. The Valsalva's maneuver as a shared pathophysiologic mechanism is mentioned as well. ⋯ Sexual headaches are divided into three subtypes, based on the onset time, related to orgasm. The clinical characteristics of each type are presented, and their etiologies pointed out. The diagnostic approach is discussed, as well as the nonpharmacologic and pharmacologic treatment options.

ReviewModern management of the cancer anorexia-cachexia syndrome.
The cancer anorexia-cachexia syndrome is common, occurring in 80% of patients with advanced-stage cancer, and it is one of the most frequent causes of death in patients with cancer. It is a complex problem involving abnormalities in protein, carbohydrate, and fat metabolism. ⋯ In addition to the physical manifestations, the resulting abnormalities have a significant psychologic effect on patients and their families. Although there is no treatment to reverse the process, pharmacologic and nonpharmacologic measures can enhance food intake and improve quality of life.

Most patients who have been diagnosed with cancer will experience pain at some point during the course of their disease. Often, opioid analgesics are not enough to completely alleviate the patient's pain and the selection of appropriate adjunct analgesic agents is critical. This article reviews the mechanisms of action and analgesic effects of several classes of antidepressants to enable the clinician to select the appropriate agent for the patient.

Control of malignant pain and related symptoms is paramount to clinical success in caring for cancer patients. To achieve the best quality of life for patients and families, oncologists and palliative care clinicians must work together to understand problems related to psychologic, social, and spiritual pain. ⋯ We discuss clinical experience with several classes of drugs that are currently used to treat cancer pain: 1) nonsteroidal anti-inflammatory drugs, with emphasis on cyclooxygenase-2 inhibitors; 2) opioid analgesics, with specific emphasis on methadone and its newly recognized value in cancer pain; 3) ketamine, an antagonist at N-methyl-d-aspartate receptors; and 4) bisphosphonates, used for pain resulting from bone metastases. New concepts that compare molecular actions of morphine at excitatory opioid receptors, and methadone at nonopioid receptor systems, are presented to underscore the importance of balancing central nervous system excitatory (anti-analgesic) versus inhibitory (analgesic) influences.

ReviewPostdural puncture headache: the role of prophylactic epidural blood patch.
Prophylactic epidural blood patch may prevent postdural puncture headache that develops after intentional or inadvertent dural puncture. However, despite earlier reports that this procedure was of value, subsequent studies have failed to show it has significant advantages over delayed blood patch. ⋯ At the present time, most centers do not routinely offer prophylactic blood patches, and those that do report a variable success rate. A recent case study of permanent neurologic deficit after prophylactic epidural blood patch has also raised some concern about the safety of this prophylactic technique.
