Glucagon-like peptide-1 (7-36) amide (glucagon-like insulinotropic peptide, or GLIP) is a gastrointestinal peptide that potentiates the release of insulin in physiologic concentrations. Its effects in patients with diabetes mellitus are not known. ⋯ GLIP has an antidiabetogenic effect, and it may therefore be useful in the treatment of patients with NIDDM:

Effects of desipramine, amitriptyline, and fluoxetine on pain in diabetic neuropathy.
Amitriptyline reduces the pain caused by peripheral-nerve disease, but treatment is often limited by side effects related to the drug's many pharmacologic actions. Selective agents might be safer and more effective. ⋯ Desipramine relieves pain caused by diabetic neuropathy with efficacy similar to that of amitriptyline, offering an alternative for patients unable to tolerate the latter. Blockade of norepinephrine reuptake is likely to mediate the analgesic effect of these antidepressant drugs in diabetic neuropathy. Fluoxetine, which blocks serotonin uptake, is no more effective than placebo for the relief of pain.

In the past decade there has been an increase in the use of treatment designed to conserve the breast for women with breast cancer. The extent to which such treatment has been adopted in various regions of the country and whether characteristics of hospitals and patients predict its use is not known, however. ⋯ There is substantial geographic variation in the use of breast-conserving surgery, which cannot be explained by differences in hospital characteristics. Hospital characteristics that were independently redictive of greater use of breast-conserving surgery were the size of the metropolitan area, the status of the institution as a teaching hospital, and the availability of radiation therapy and geriatric services.
