It has been proposed that pain treatment evaluation is hindered by heterogeneous properties of patient samples. Therefore, to facilitate pain treatment evaluation in this psychological study, a heterogeneous group of chronic low back pain patients was classified into more homogeneous subgroups. Two designs were used to compare the outcome by the "functioning activation" and the "spa resort" type of rehabilitation. ⋯ In the second design, the pain patient subgroups, homogenized by cluster analysis technique in accordance with the psychological profiles of functioning, were compared in their response to treatments. The results indicated that the outcome evaluation was facilitated by the latter design releasing more specific information about the effects of the program quality, the patient characteristics, and their interaction on the improvement by rehabilitation. It was concluded that in treatment outcome analysis, the subgroup's homogeneity must be considered.

Vitamins of the B group have long been used to treat neuropathies of different origins and the accompanying pain. A combination of the vitamins B(1), B(6), and B(12) prevents the slowing of impulse conduction produced by tetanic stimulation in diabetic mice. In patients suffering from diabetic neuropathy, B vitamins alleviate pain in the upper extremities. ⋯ It has recently also been reported that a combination of the vitamins B1, B6, and B12 has analgesic properties in non-neuropathic conditions. In animal experiments, B vitamins diminish nociceptive responses in spinal and thalamic neurones and potentiate the antinociceptive effect of analgesic agents. Similarly, B vitamins potentiate the therapeutic effect of diclofenac in patients suffering from acute low back pain.

An unselected sample of outpatient subjects (n = 330) with localized nonspecific low back pain (LBP) was studied. Investigation consisted of clinical assessment, physical examination, and psychiatric interview based on the DSM-III classification. A psychiatric disorder, according to the DSM-III criteria (axis I) was found in 41% of the subjects. ⋯ Cluster analysis provided support for a four-group classification of low back pain, which may be interpreted through the relationships between psychological disturbances and the LBP clinical features. The results call for further investigation of the complex relationship between psychological disturbances and back pain. However, clinicians must be aware of the interest of a minimal psychiatric assessment in low back pain patients: psychiatric disorders frequently appear in these patients and an appropriate treatment of the psychiatric syndrome may reduce back pain.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of Sprotte and Quincke needles with respect to post dural puncture headache and backache.
The objective of this study was to compare 24-gauge Sprotte and 25-gauge Quincke needles with respect to post dural puncture headache and backache. ⋯ Our data indicate that Quincke needles should not be used with the needle bevel inserted perpendicular to the dural fibers. The Sprotte needle does not solve the problem of post dural puncture headache and backache.

Noninvasive evaluation of low back and leg pain has progressed rapidly over the past decade. The development of computed tomography, single-photon emission-computed tomographic bone scan, and magnetic resonance imaging has markedly increased diagnostic accuracy in detecting pathologic conditions. With this increased accuracy has come recognition of a 50% prevalence of underlying abnormalities in patients between 20 and 60 years old who have no symptoms. ⋯ The patient's presenting symptoms are also used to determine the most cost-effective and efficacious use of initial diagnostic imaging evaluation. In a minority of patients the findings on noninvasive imaging either will not correlate with the patient's symptoms or will demonstrate multiple abnormalities that could account for the patient's symptoms. In these patients, invasive techniques are extremely helpful in defining a pain generator or pain generators.(ABSTRACT TRUNCATED AT 400 WORDS)
