Dansyl amino acids having a free amino group and an asymmetric carbon atom were examined as a labeling reagent for chiral compounds containing carboxylic moieties to realize enantiomeric separation as well as fluorimetric determination. We tested dansyllysine by reacting it with (+)- and (-)-ibuprofen as a model carboxylic enantiomer. As the intramolecular carboxylic moiety of the dansyl amino acid interfered in the condensation reaction to form an amide bond with the carboxylic acid, the moiety was masked by methylation with trimethylsilyldiazomethane before the reaction. These derivatives were reacted with (+)- and (-)-ibuprofen and better enantiomeric resolution was achieved with methylated dansyllysine on a reversed-phase column. The derivatisation reaction was facilitated by the use of catalysts that are commonly employed in peptides synthesis. The reaction was completed within 5 min at room temperature when diethyl phosphorocyanidate was used. Due to the dansyl moiety, methylated dansyl-lysine enables a sensitive determination of ibuprofen with a fluorescence detector, in addition to the capability of enantiomer resolution. In tests, the detection limits for (+) and (-)-ibuprofen were 4 pmol per injection (S/N=3) at an excitation wavelength of 340 nm and an emission wavelength of 523 nm. Linear responses for the determination of (+) and (-)-ibuprofen in human urine were also demonstrated (r > or = 0.998) in the range from 10 to 1000 ng/ml. The precision and accuracy for urine samples spiked with (+)- and (-)-ibuprofen at 10, 100 and 1000 ng/ml were <10.1 and <14.6% (n=4), respectively.

We previously showed the non-steroidal anti-inflammatory drug (NSAID) ibuprofen suppresses inflammation and amyloid in the APPsw (Tg2576) Tg2576 transgenic mouse. The mechanism for these effects and the impact on behavior are unknown. We now show ibuprofen's effects were not mediated by alterations in amyloid precursor protein (APP) expression or oxidative damage (carbonyls). Six months ibuprofen treatment in Tg+ females caused a decrease in open field behavior (p < 0.05), restoring values similar to Tg- mice. Reduced caspase activation per plaque provided further evidence for a neuroprotective action of ibuprofen. The impact of a shorter 3 month duration ibuprofen trial, beginning at a later age (from 14 to 17 months), was also investigated. Repeated measures ANOVA of Abeta levels (soluble and insoluble) demonstrated a significant ibuprofen treatment effect (p < 0.05). Post-hoc analysis showed that ibuprofen-dependent reductions of both soluble Abeta and Abeta42 were most marked in entorhinal cortex (p < 0.05). Although interleukin-1beta and insoluble Abeta were more effectively reduced with longer treatment, the magnitude of the effect on soluble Abeta was not dependent on treatment duration.

Using patient related examples, the toxicity of nonsteroidal antiinflammatory drugs and disease modifying antirheumatic drugs (DMARD) in juvenile arthritis (JA) is discussed. DMARD combinations are also reviewed. Gastrointestinal side effects are not emphasized. Rather, central nervous system, hepatic, and renal effects are discussed. Ibuprofen is safer than aspirin and has a generally good record. Although data is not excellent and often relies on open studies, hydroxychloroquine is probably the safest DMARD. Methotrexate appears safe, but studies in adults mandate some continued caution in its use in children. Combination DMARD therapy, while used, is dependent on largely open or anecdotal data in adults. The efficacy and toxicity of DMARD combinations are not well understood.

The electrophoretic mobility of selected acidic and basic test solutes have been determined in non-aqueous media prepared by adding various combinations of ammonium acetate, sodium acetate, methane sulphonic acid and acetic acid to acetonitrile, propylene carbonate, methanol, formamide, N-methylformamide, N,N-dimethylformamide and dimethylsulphoxide, respectively. The apparent pH (pH*) of these non-aqueous media have been measured and it was found that pH* is an important factor for the separations in non-aqueous capillary electrophoresis. However, in some solvents the concentration of sodium acetate has a strong influence on the mobility despite very small changes in pH*. Due to the fact that a change in one parameter influences a number of other parameters it is very difficult to conduct systematic studies in non-aqueous media and to compare the migration of the species at fixed pH* values from one solvent to another. Thus pH* is only of value for comparison when used with a specific solvent or solvent mixture. The viscosity of the above-mentioned solvents were measured at various temperatures and means to adjust the viscosity of the non-aqueous media used for capillary electrophoresis are discussed and the separation of ibuprofen and its major metabolites in urine is used as an example.
Epidural analgesia for minilaparatomy cholecystectomy improves pain relief in the immediate postoperative period, compared to intramuscular morphine. Pulmonary and endocrine-metabolic function is not changed to such degree after minicholecystectomy that epidural analgesia can be demonstrated to have beneficial effects.

Migraine phenotype differs somewhat in the developing brain, and childhood episodic syndromes may arise before typical migraine headache. Diagnosing pediatric migraine may be difficult because of children's language and cognitive abilities. The risk of underestimating migraine in pediatric age is high. An adequate diagnosis is important to maintain a good quality of life and to avoid inappropriate therapy.

Buffered ketoprofen (12.5 mg) provides effective pain control in the early postoperative period after third molar surgery. This ketoprofen preparation was also superior to ibuprofen (200 mg) with respect to both reducing pain intensity and providing an earlier onset of pain relief.
