    Description / Table of Contents: Summary In a series of 6 patients out of 47 cases with extrarenal hyperparathyroidism we investigated the clinical, laboratory and ultrastructural peculiarities of acute hyperparathyroidism. It was found that there are characteristic differences between both entities which, however, are fluid. Clinically more severe were neuromuscular psychiatric and mental signs. In the laboratory parameters PTH determined by radio-immunoassay and calcium were higher whereas hemoglobin was lower. The weights of the adenomas did not differ in both groups and this was also true for light microscopy findings. Electron microscopy revealed accelerated hormone extrusion and autodigestion of retrieved membrane material in the cases of acute hyperparathyroidism similar to characteristics of parathyroid cells stimulated by hypocalcemia in tissue culture.
    Notes: Zusammenfassung Bei 6 Kranken mit akutem Hyperparathyreoidismus werden klinische Befunde, Labordaten und Besonderheiten in der Ultrastruktur der Nebenschilddrüsen den Daten von 47 Kranken mit extrarenalen Hyperparathyreoidismus gegenübergestellt. Typische Unterschiede konnten aufgezeigt werden, die Übergänge sind aber fließend. Beim klinischen Verlauf waren neuromuskuläre Zeichen, psychiatrische und Störungen des Bewußtseins deutlicher in der ersten Gruppe. Beim Vergleich der Labordaten war radioimmunchemisches Parathormon höher in der akuten Gruppe und das Hämoglobin niedriger. Das Gewicht der Adenome und die lichtmikroskopischen Befunde waren nicht unterschiedlich in beiden Gruppen. Die elektronenmikroskopischen Studien des Adenomgewebes zeigten eine erhöhte Hormonausschüttung mit einer deutlichen Beschleunigung der Autodigestion von Membranmaterial. Diese Veränderungen entsprechen etwa denen, wie sie an Nebenschilddrüsengewebe in der Gewebekultur nach Stimulation durch Hypocalciämie gefunden werden.

    Notes: Summary In an attempt to derive diagnostic concepts for thyroid diseases we present pathophysiological models for the prevalent thyroid disorders. ‘Euthyroid goiter’ is a disease mainly caused by iodine deficiency but an additional immunepathogenesis was recently proposed. The ‘immunthyropathy’ is the thyroid disease with orbitopathy and other extraglandular immunological manifestations. A complete model of the immunological phenomena which begin with a tolerance defect is given, and both the T-cell- and B-cell-mediated pathways are detailed. The complex interaction of immunoglobulins at the thyroid-stimulating hormone receptor and their dependency on human leukocyte antigen loci are presented. The peripheral metabolism depends ultimately upon a prevalence of thyroid gland stimulation (thyrotoxicosis) or glandular destruction (hypothyroidism) and this is true for overt thyroid disease under antithyroid drug therapy or any other therapy. Euthyroidism during ‘immunethyropathy’ is presented as an equilibrium between thyroid stimulation and destruction. This concept allows an exact description of the thyroid disease and the resulting clinical situation provided that established laboratory tests are used as suggested by the model. ‘Disseminated thyroid autonomy and autononous thyroid adenoma’ develops during goitrous thyroid disease as a consequence of uncoupling of thyroid cellular growth stimulation, iodine utilization, and thyroid hormone synthesis. The polyclonal origin seems more frequent than monoclonal foci. The size of autononous tissue and individual iodine supply determines the endocrine function in this disease. The TRH test monitors with great sensitivity subtle increases in T4 or T3 production and indicates critical clinical situations earlier than the scintiscan. The exposure of the thyroid gland to large amounts of iodine precipitate thyroid storm and this has lead us to propose a protocol for patients in danger which seems clinically useful. It is hoped that the diagnostic procedures for thyroid diseases are more rational, effective, and less expensive when they are based on modern concepts of pathophysiology.
