In this study three instruments measuring disability of patients with low-back pain are presented and evaluated: (1) the Behinderungsfragebogen (RM) - a German version of the Roland & Morris disability questionnaire (RDQ) (2) a numerical rating scale measuring disability in general and (2) eight numerical rating scales measuring specific dimensions of disability (standing, sitting, walking, driving a car, carrying light loads, carrying heavy loads, sleeping, and sexual intercourse). ⋯ The RM is an instrument measuring patients' perception of their disability that offers simple, fast practicability for patients and tester. The 2 rating scales: The 8 numerical rating scales measuring specific dimensions of disability (QL3) offer all the advantages of the numerical rating scale measuring disability in general (QL1) (simple instruction, high plausibility for the patients, and simple, fast practicability), but they provide more information about the patient's disability, which allows comparisons of disability at different times in the therapeutic process. Numerical rating scales are not suitable for patients with poor ability to abstract. For these patients it is necessary to use a questionnaire which asks concretely about what the patient can or cannot do (e. g. RM). Because of its better psychometric properties, the QL3 should be favored over the RM.

Immune responses are an input source of modulation/modification for the peripheral nervous system that can result in pain and/or peripheral neuropathy. The resulting pain can be a significant debilitating component of many diseases as well as an untoward side effect of treatment. This paper briefly describes three sources of peripheral neuropathy generated in the presence of, or associated with, an immune response. ⋯ The body, in an attempt to rid itself of a tumor or an invading bacterial infection or virus, attacks its nervous system due to molecular mimicry; this results in, respectively, paraneoplastic neuropathy or inflammatory polyneuropathy. The third neuropathic pain syndrome is iatrogenic and occurs after administration of an antibody to GD2 ganglioside as an immunotherapy for neuroblastoma. This paper will attempt to point out some common elements in their neuropathologies and mechanisms.

In chronic pain patient's diagnostic and therapy planning many complex information must be evaluated and analysed. The variety of data cannot be mastered without assistance of a database tool adapted to these special need. ⋯ Due to its ability of export into other databases and already enclosed routines QUAST permits an internal assurance of quality of process and outcome in pain management. It also can be an instrument of an external quality assurance. QUAST is at present the only computer system available in Germany, to fulfil the required prerequisites for adequate quality control.

The somatosensory system of preterms and newborns differs substantially from adults. These differences are of considerable preclinical and clinical interest. Maturation of A- and C-fibre synaptic connections in the dorsal horn and development of descending inhibition from the brainstem all take place postnatally in the rat. In early stages of development there is no definite spatial separation in the dorsal horn between the nociceptive and the non-nociceptive system. In preterms but not in adults non-noxious stimuli can induce central sensitization. Many neurotransmitters and signalling molecules involved in pain pathways are expressed early in the developing nervous system but do not reach adult levels for a considerable period. More important, receptors are frequently transiently overexpressed or expressed in areas during development where they are not seen in the adult and may have a different functional profile. The descending pain inhibitory system that provides an important protection against central sensitization develops later than the ascending nociceptive system. Thus, during a critical period of time the immature nociceptive system is highly vulnerable. For example, neonatal circumcision in the absence of analgesia results in increased pain responses during subsequent routine vaccination months later. ⋯ In view of the changing nature of neonatal somatosensory and pain pathways and the vulnerability of the developing nervous system to alterations in sensory stimulation it is important that preterms and newborns need the care of a specialist for prevention and treatment of pain to avoid suffer and long-term changes in the nervous system.

Interventional pain management is a dynamic field with changes occurring on a daily basis, not only with technology but also with regulations that have a substantial financial impact on practices. Regulations are imposed not only by the federal government and other regulatory agencies, and also by a multitude of other payors, state governments and medical boards. Documentation of medical necessity with coding that correlates with multiple components of the patient's medical record, operative report, and billing statement is extremely important. ⋯ Hence, these guidelines do not constitute inflexible treatment, coding, billing or documentation recommendations. It is expected that a provider will establish a plan of care on a case-by-case basis taking into account an individual patient's medical condition, personal needs, and preferences, along with physician's experience and in a similar manner, billing and coding practices will be developed. Based on an individual patient's needs, treatment, billing and coding, different from what is outlined here is not only warranted but essential.
