[Neuromuscular excitability and conduction in cases of hypoparathyroidism]

The patients with hypoparathyroidism were studied carrying out: a) tetanic test (PT) for assessment of the degree of neuromuscular excitability and b) double stimulus test (PBP) for assessment of the efficiency of neuromuscular conduction. In six patients low values of calcium, high values of phosphorus and normal values of magnesium were found. In the remaining patients calcium level was decreased also but the phosphorus level was normal, while that of magnesium was low. In all patients the PT was normal while the PBP showed in the first group reduced efficiency of conduction and in the remaining cases increased neuromuscular conductivility. The possible interpretation of obtained results is discussed.
