Review Comparative Study
[Treatment of idiopathic headache in childhood - recommendations of the German Migraine and Headache Society (DMKG)].
According to the principles of evidence-based medicine, the controlled studies on the treatment of idiopathic headache in childhood have been analysed and compiled to treatment recommendations. For the acute treatment of migraine attacks or tension-type headache, ibuprofen (10 mg per kg body weight) or acetaminophen (15 mg per kg body weight) are recommended with highest evidence, intranasal sumatriptan (10 to 20 mg) can be given as second choice. ⋯ No controlled studies are available for the treatment of further headache types. First line methods for the non-drug treatment of headache in childhood are relaxation therapies, biofeedback, and specific training schedules.

Gabapentin has been shown to reduce pain associated with diabetic neuropathia and postherpetic neuralgia. To date it is not known, whether gabapentin is generally effective in other types of pain. It was therefore the aim to study gabapentin in patients suffering from intractable pain with respect to efficacy, predictive factors and side effects. ⋯ Gabapentin was effective in approximately 50% of pretreated patients with intractable pain. Neuropathic pain responded better than pain of other origine. Allodynia may be a predictive factor for a positive treatment effect.

Surgery in acute and/or chronic low back pain is still a matter of intensive and controversial discussions. A vast number of minimally invasive or so called semi-invasive procedures have been published in the last 3 decades, but evidence-based data on efficacy and benefit of most of these techniques are still lacking. However, empirical data suggest good or at least satisfactory clinical results for a limited number of procedures if they are applied under restrictive indication criteria. ⋯ In general a restrictive indication for surgery must be recommended especially for spinal fusion procedures. Non-fusion techniques such as intradiscal electro thermal therapy or spine arthroplasty with replacement of nucleus pulposus or total disc show promising early results; however, little is known about the long-term effect. It should be a principle to apply surgery in the least invasive way.

Randomized Controlled Trial Clinical Trial
[Increase in strength after active therapy in chronic low back pain (CLBP) patients: muscular adaptations and clinical relevance].
Active treatments are advocated for the management of non-specific chronic low back pain (CLBP), although few studies have documented the relative efficacy of differing types of programme. A number of the available treatments comprise exercise routines on specially designed training machines, which are ostensibly better disposed to reverse the compromised trunk muscle function displayed by these patients than are 'free exercise' programmes. However, in using these muscle-training programmes, the physiological or anatomical adaptations that might account for the improved performance are rarely investigated, let alone identified. This is an important issue, because if the 'newly-acquired strength' is mostly specific to performance on the devices on which the patient has trained and been tested, and reflects the skill in executing these particular tasks, this will not necessarily assist the patient during performance of his/her everyday activities. The aims of the present study were (1) to quantify the changes in back muscle performance in chronic LBP patients following 3 months active therapy, and (2) to analyse the corresponding changes in activation and cross-sectional area of the paraspinal muscles. ⋯ The superior trunk strength shown by the devices group post-therapy was considered to be attributable, in part, to a 'learning effect', of the type often seen when training and testing are carried out on the same machines. These gains are considered to be mostly 'task-specific'. However, part of the improvement in strength after active therapy (in all groups) also appeared to be due to an increased neural activation of the trunk muscles. These positive effects should be transferable to the performance of everyday activities for which the same muscles are employed, although the percentage improvement is probably not as high as the measured increase in strength might suggest. Possible roles for improved co-ordination and changes in motivation and/or pain tolerance after therapy cannot be excluded. No differences in the clinical outcome were observed between the three therapy groups, and the changes in physical performance after therapy did not correlate with the clinical outcome. It is therefore questionable whether strength measurements have any clinical significance in documenting the success of rehabilitation programmes, other than on a motivational basis. The results of the present study suggest that the value of supervised active therapy programmes does not reside in the reversal of specific muscular deficiencies, but rather in the provision of a source of confirmation/encouragement for the patient, that movement is not harmful, and a foundation upon which to further build. Whether the utilisation of specific training devices, or individual instruction, is necessary to elicit these particular effects is questionable.

The central and lateral lumbar canals constitute complex osteofibrous neurovascular tunnels, allowing movement and deformation of the spine without loss of their main configuration. Intervertebral discs play an important role in determining their configuration. Disc degeneration may alter or even threat the functional anatomical relationships between successive adjacent "juncturae" of the vertebral column. ⋯ The sympathetic nerve plexus inside the anterior longitudinal ligament and the SNVs provide a network of nerve fibers around the vertebral bodies and intervertebral discs. These pathways explain the sympathetic component of the innervation of a number of spinal structures. The dorsal ramus innervates the facet joints at the corresponding level and one below, before it gives off muscular and cutaneous branches.
