[The role of paraclinical studies in the diagnosis of hypomagnesemia spasmophilia].

Abstract

Assuming that Ca+2 and Mg+2 play an important role in the cell (especially the neuronal and muscular ones) membrane excitability, this paper presents the place that the paraclinical specific investigations have in the proper diagnose of normal calcium serum level hypo-magnesium spasmophilia. A number of 52 patients presenting significant clinical spasmophilia, of age between 21 and 55 years old, from different professions and social classes, were selected for this study. Paraclinical investigations (spectrophotometry) showed a normal serum calcium level (an average of 9.22 mg%); also, a decrease of Mg+2 serum level (an average of 1.41 mg%) and normal levels for Na+ (3.04 g/l) and K+ (0.21 g/l). The electrophysiological investigations (EMG, EEG, VCN m, EKG) performed showed, on the EMG recordings, in 85% of the cases the presence of the typical spasmophilic repetitive discharges, increased when using compression ischemia and 3 minutes hyperventilation, while on the EEG recordings, most patients demonstrated the presence of diffuse or mainly frontal lobe cortical bioelectrical activity alteration, either in spontaneous conditions or after specific stimulation (3 minutes hyperventilation or SLI). The muscle bioelectrical activity was analyzed by mean of EMG recordings--a decrease of VCN m was detected on the SPE nerve (34.4 m/s) and also on the SPI nerve (34.2 m/s) The EKG recordings performed showed in 5% of the cases the presence of the ventricular repolarization disturbances (flat T waves). After receiving a proper treatment which included oral administration of calcium and magnesium gluconolactate, magnesium gluconolactate with B6 vitamin or Trimagant, there were important changes of all the studied parameters and so, as a specific therapy, we recommend the use of Mg+2 compounds, because it demonstrates a significant improvement of the clinical symptoms in spasmophilia and has no danger to precipitate in the body as Ca+2 exceeding does.
