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.

ReviewModern management of cancer-related intestinal obstruction.
Malignant-associated bowel obstruction remains a common and perplexing problem for patients with advanced gynecologic and gastrointestinal malignancies. The ability to locate and define its cause preoperatively has improved with the advent of computed tomography. Initial clinical experience with half-Fourier acquisition single-shot turbo spin-echo magnetic resonance imaging (HASTE MRI) and virtual colonoscopy is exciting. ⋯ Stent placement for upper and lower bowel obstructions is an option in nonoperable patients. Pharmacologic symptom management for intestinal obstructions consists of an opioid, an anticholinergic, and an antiemetic. Octreotide, either alone or added to the original regimen, will palliate symptoms that are resistant to the three-drug combination.

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.

Constipation is an expected side effect of opioid use and as such should be treated prophylactically. However, because it is often overlooked and under-appreciated it is one of the most common reasons patients avoid or abandon opioid use and, as a result, suffer pain needlessly. Thorough assessment, ongoing evaluation, and patient teaching are key factors in establishing an effective bowel regimen. ⋯ Once any impactions have been eliminated, a regular regimen of senna and docusate is recommended. Dietary modifications, fluids, and exercise are important but usually not sufficient to overcome opioid-induced constipation. Although many of the medicines that are used to treat pain and related symptoms come with a significant potential for distressing side effects, it is important to understand that most side effects, especially constipation, can be managed and quality of life can be preserved without sacrificing needed analgesia.

This article reviews the features of an uncommon malady termed "the exploding head syndrome." Sufferers describe terrorizing attacks of a painless explosion within their head. Attacks tend to occur at the onset of sleep. The etiology of attacks is unknown, although they are considered to be benign. Treatment with clomipramine has been suggested, although most sufferers require only reassurance that the spells are benign in nature.
