[Various technical diagnosis problems in the early diagnosis of parathyroid dysfunctions]

During the last years the functional diagnostics of the parathyroid glands has been considerably enlarged. Nevertheless, the results concerning an early recognition of conditions of hypofunction and hyperfunction are up to now unsatisfying. Despite of the increasing diagnostic importance of the direct determination of the parathormone which is at first available only in special institutions in these cases methodical problems play a less important part than the still not infrequent appearing misunderstanding of the adequate basic disease. The without doubt great variability of the clinical phenomenology of the parathyreogenic dysfunctions is particularly to be established in their initial stages. The demonstrated processes of investigation apart from the description of complexes of diagnostic problems summarize the experiences of many years of a treatment of outpatients directed to the forms of disturbances of the parathyroid glands.
