AIM OF INVESTIGATION: The purpose in this study was to develop an original pain questionnaire in the Spanish language, following the model of the Mc Gill Pair, Questionnaire (MPQ), in order to dessing a useful clinical tool for pain practitioners of the Spanish speaking countries. METHODS: A vocabulary selection was made from previous Spanish MPQ adaptations and :;ranslaticns. already published, medical literature and pain patients. After gathering 261 descriptors, a selection was made of these and the final number was substantially reduced. The selection of descriptors as well as their ordering into classes and subclasses were carried out by different groups of 30 university graduates (15 psychologists and 15 filologists), 30 medical doctors and 30 pain patients. The final vocabulary was formed with those words which had been selected with the highest frequency. Next, an intensity value was assigned to each descriptor using a visual analogue scale. Those words which proved to have a significant level of at least 5 % of intensity variation were finally selected. RESULTS: A significant difference was found between the final vocabulary of this investigation and the previous Spanish translationsof the MPQ which have been published up till now. This confirms our hypothesisthat in order to dessing a reliable clinical tool to assess pain, it was necessary to reproduce the steps already followed by other investigators of different languages rather than making a simple translation or adaptation from the MPQ or any other questionnaire into Spanish.

AIM: Patients ’ suffering from hypomagnesemia have developed muscle weakness, restlessness, leg cramps, paresthesias and decreased concentration. These are all symptoms frequently described by chronic pain patients. In addition, chronic pain patients often abuse alcohol which can also cause hypomagnesemfa. These observations led us to a pilot investigation of magnesium levels in chronic pain patients. PROCEDURE: Serum magnesium levels (normal value 1.6 2.6 MG/DL) were measured in 201 consecutive chronic pain patients. Any magnesium level below normal was repeated and if indicated the patient was treated. RESULTS : The magnesium values for the patient group were found to be normally distributed with the mean (1.777), mode (1.7) and median (1.8) values being nearly equal. The range for all patients was between .S - 2.4 MG/DL and 95% of the magnesium levels were between 1.2 2.2 MG/DL. 14.97. of the patients had abnormal values below 1.6 NG/DL. CONCLUSIONS: (1) A sfgnif icant proportion of chronic pain patients appear to have clinically defined hypomagnesemia; A comparison of the ranges between normals (2) and chronic pain patients indicates that the magnesium distribution of chronic pain patients is skewed to the lower end of normal values. This pilot study indicates that further studies of serum magnesium levels in chronic pain patients are indicated.
