The number of old and very old persons is increasing and there is evidence that aging coincides with chronic painful conditions. Pain induces behavioural disorders that have been so far poorly identified in old and even less in very old animals. ⋯ The correlation between observational and experimental pain scores stresses the reliability of non-invasive measures for pain evaluation in senescent populations. The dichotomy between neuropathic and acute pain perceptions with age needs to be further investigated and would help to better understand the reasons of this uneven pain perception and expression with age.

Multicenter Study Clinical Trial
Paediatric cancer pain management using the WHO analgesic ladder--results of a prospective analysis from 2265 treatment days during a quality improvement study.
To collect data on pain management in paediatric oncology with respect to the WHO ladder approach. SETTING, DESIGN, PATIENTS AND METHODS: Eight German tertiary care paediatric oncology centres prospectively documented all their in-patient pain treatment courses from June 1999 to December 2000. Pain was scored using a 1-6 faces scale. ⋯ WHO-guidelines were closely followed in Germany and seem to provide effective analgesia for children with cancer pain. In our patient group there is no evidence that a combination of an opioid with a non-opioid is more effective than opioid therapy alone in in-patient paediatric oncology pain treatment.

Clinical studies suggest that tramadol-induced analgesia is partially antagonized by ondansetron. ⋯ The interaction of tramadol with ondansetron or droperidol on antinociception can be antagonistic or additive, depending on the type of stimuli. Both anti-emetics antagonize the anti-transit effects of tramadol. The results demonstrate antagonism between tramadol and the two anti-emetics for analgesia and inhibition of gastrointestinal transit, supporting previous clinical studies.

Randomized Controlled Trial
Peroperative ketamine and morphine for postoperative pain control after lumbar disk surgery.
Ketamine, a N-methyl-D-aspartate receptor antagonist, may reduce postoperative opioid demand and improve postoperative analgesia. ⋯ Ketamine small-dose, combined with morphine improves postoperative analgesia and reduces opioid-related side effects in lumbar disk surgery.

The aim was to psychometrically evaluate the Swedish version of the Multidimensional Pain Inventory (MPI-S) and the "brief screening version of MPI-S" for use in an elderly sample. ⋯ The MPI-S instrument may not be very useful for measuring pain among frail elderly. The brief screening version may instead be a better alternative to the full version of the MPI-S. However, the small number of observations may be the reason to the lack of fit, and further studies are warranted.
