Computer monitoring is an effective method for improving the detection of adverse drug reactions in inpatients. The excess length of stay and costs caused by adverse drug reactions are substantial and might be considerably reduced by earlier detection.

In addition to general kyphoscoliosis, grotesque inclination and false positioning of the head are additional characteristics of Bekhterev's spondylitis. The causes of these changes are often fractures and are seldom of rheumatic nature. Although accidents can cause severe instability in the whole, stiffened vertebral column, minor trauma are not usually recognised. Even slight sintered fractures of the ventral vertebral area usually have a dorsal distraction component and can later increase to full dislocation. Severe deformation, which alone indicates the degree of damage, may not taken seriously until neurological changes occur. A definitive differentiation from an Anderson lesion is difficult, although this is of no relevance to the operative-therapeutic methods used. The earliest possible recognition of such a fracture or instability is of greatest prognostic significance to correct the situation without great difficulty, if necessary by using a Crutchfield clamp or a halo vest. If the fracture is found too late, such easy methods of correction are no longer possible and a more complex procedure is necessary. Whereas satisfactory stability can already be achieved via ventral access in the case of complete repositioning of the fracture, in the case of severe kyphosis and rigidity a combined dorsoventral approach involving several operations is necessary and the risk of complications is much higher.

The detection rate of ADRs would almost be doubled by a computerized monitoring system analyzing laboratory data. Implementation of a computer monitor system that automatically generates laboratory signals may help to identify ADRs in children, and to reduce morbidity and hospital stay, as well as costs.

Awareness of existing ADRs on hospital admission and appropriate prescribing prior to hospital admission require attention. Early detection of ADRs on hospital admission can be achieved by the use of computer support systems. Many ADRs could be prevented by adhering to indications and contraindications.

These data show that meloxicam inhibits TXB2 generation at clinically relevant doses, although less potently than diclofenac. Thus our data suggest that the COX-2 preference of meloxicam observed in vitro may not result in clinical advantages when the higher dose of 15 mg is needed. Because of the increase in EC50 at steady state, COX-1 is relatively spared when the lower dose of 7.5 mg is administered.
