Randomized Controlled Trial Clinical Trial
A comparison a amitriptyline and maprotiline in the treatment of painful polyneuropathy in diabetics and nondiabetics.
To compare amitriptyline and maprotiline in the treatment of painful polyneuropathy in diabetics and nondiabetics. ⋯ From the present results and the literature, it is concluded that tricyclic antidepressants with a pharmacologic profile similar to amitriptyline are the most effective drugs in the treatment of polyneuropathy pain in both diabetic and nondiabetic patients.

The purpose of this study was to determine the distribution of referred pain from the lumbar zygapophyseal joints (L1/2 to L5/S1) and the medial branches of the lumbar dorsal rami (Th12 to L5) in a large number of patients with chronic low back pain. ⋯ A total of 71 joints and 91 medial branches were studied in 48 patients. The distribution of referred pain from the L1/2 to L5/S1 zygapophyseal joints, and the medial branches of the dorsal rami from L1 to L5 were similar for each level stimulated, and the overlap of referred pain between each level was considerable.

To evaluate the contribution of pain severity, physical pathology, demographic factors, initiators of symptoms, affective distress, behavioral expressions of pain, and functional activity levels in physicians' decisions to prescribe opioid medication for chronic noncancer pain patients. ⋯ Physicians' practice in prescribing of opioids appears to be influenced most by patients' nonverbal communications of pain, distress, and suffering. Some of the factors not directly evaluated in this study that may also contribute to the decision to prescribe opioids for chronic noncancer pain patients are discussed.

Tricyclic antidepressants (TCA) have been shown to provide analgesia for a variety of neuropathic and headache pain syndromes regardless of the presence of depression. There is a high incidence of depression in patients with chronic pain, thereby making tricyclic antidepressants particularly suitable for chronic pain patients. We wanted to study patterns of use of tricyclic antidepressants in our Pain Management Center (Beth Israel Hospital, Boston, MA, U.S.A.) primarily to answer four questions: (1) What percentage of all patients were treated with tricyclic antidepressants? (2) How many patients were treated with each antidepressant, and what was the dose range used for individual antidepressants? (3) Were tricyclic antidepressants beneficial for chronic pain, and was that response dependent on a particular dose? (4) Did patients receive an adequate TCA trial, and what factors led to the discontinuation of a TCA trial? ⋯ Tricyclic antidepressants were used in 25% of patients referred to a multidisciplinary pain center and were commonly used in low to intermediate doses, even in situations in which there were neither side effects nor optimal clinical response.

To evaluate the relationships between patient and physician pretreatment expectations of pain relief and subsequent pain relief reported by chronic pain patients immediately after treatment. ⋯ The results of this study suggest that physicians are better predictors than are patients of patients responses to these procedures and/or that physicians may somehow subtly communicate their expectations to patients during the procedure, and these expectations then influence patient response. Patient pretreatment expectations may not always play a significant role in nonspecific treatment effects.
