[Biochemical and x-ray changes in thyroid osteopathy].

Moderately elevated calcemia, increased urine calcium excretion, normal values of phosphate clearance and tubular phosphate resorption, elevated alkaline phosphatase were found in 50 patients with clinically confirmed thyrotoxicosis. With calcium loading, an essential calcium elevation in serum was determined as well as a delayed restoration to the norm of the latter, providing grounds to admit an insufficiency of hypocalcemia leading systems, thyrocalcitonine resp. The characteristic features of the X-ray changes observed are described, especially of osteoporosis. The bone changes were established to be more frequent among females (64% versus 204 among males). They increase in parallel with age advancing, during and severity of the disease. The special X-grams for fine analysis of bone structure according to Meema-Heunk enable the confirmation of intracortical striation in metacarpal bones and phalanges in 56.7 per cent of the examined.

[Urinary hydroxyproline in hyperthyroidism].

the total hydroxyproline excretion in urine was investigated in 82 patients with hyperthyroidism without data fro a concomitant disease, 50 clinically healthy subjects with euthyroid struma, 10 patients with non endocrine froms of osteoporosis, 4 diabetics with not stable diabetic compensation and 4 patients with primary hyperparathyroidism. The average hydroxyproline values, in the patients with active thyreotoxicosis in 24 hours urine are 56.01-6.03 mg and 16.74 +/- 7.38 mg, after reaching the therapeutic remission. The excretion is with an average of 17.52 +/- 6.03 mg in the patients with euthyroid struma. In patients with primary hyperoparathyroidism-121.60 +/- 18.2 and in patients with diabetes mellitus-51.10 +/- 3.11, in the subjects with osteoporosis-25.83 +/- 10.88 mg. The differences between the patients with active hyperthyroidism and euthyroid struma, as well as after coming to a terapeutic remission are statistically highly significant.

[Idiopathic osteoporosis at an early age].

Two males, aged 33, with progressive pains in the spine are described as well as with high degree osteoporosis, compressive fractures of several vertebrae and a rapid evolution of the changes. The values of serum calcium and phosphorus as well as alkaline phosphatase proved to be normal. Excretion of calcium and hydroxyproline in urine were also normal, whereas phosphorus excretion was increased. It was concluded that the case concerned idiopathic osteoporosis in early age, with unknown pathogenesis. The carried out treatment with vit. D and sodium fluoride in the course of one year impeded the evolution of the bone changes in the second patient, while the anabolizing treatment in the first patient was without any effect.

[Bone metabolic disorders after prolonged treatment with antiepileptic agents in a patient with idiopathic hypoparathyroidism].

A case is reported of a patient, aged 20, with idiopathic hypoparathyroidism, manifested with the picture of epilepsy with a long treatment with antiepileptic remedies. Two years after the initiation of the antiepilertic treatment, severe skeleton disturbances occurred with manifested osteoporosis and multiple symmetric zones of bone reconstruction, hypocalcemia, hyperphosphatemia and elevated serum alkaline phosphatase. The disturbances of calcium and phosphorus level in blood are favourably affected by the application of relatively high vitamin D doses. The role of the long-term anticonvulsive treatment in the development of vitamin D resistant rickets and osteomalacia is discussed.

[Chronic recurrent pancreatitis with erosive gastritis in a patient with primary hyperparathyroidism].

A female with premary hyperparathyroidism and secondary renal lesions, as well as lesions of the stomach and pancreas is described. The initial illness was manifested by repeated renal crises. Later, gastroenterological complaints appeared--epigastralgia, vomiting, frequent hematemesis with melena. That was the cause for a gastric resection, diffuse erosive gastritis being found. After the operation, the pains and the vomiting of hematin matter repeatedly recidivated. Clinically and at the laboratory, data were formed for a chronic recidivating pancreatitis with the presence of primary hyperparathyroidism. The postoperative treatment of the parathyroid adenoma led to an improvement of the gastroenterological complaints.

[Subacute thyroiditis].

Six cases with subacute thyroiditis of De-Kerven are discussed, considered as a relatively rare disease. The clinical manifestations are analyzed as well as the diagnostic tests, evolution and treatment and the etiological factors, leading to its origination. An opinion is expressed that the disease is not so rare as considered so far.

[131-I capture by the thyroid gland during and after stopping thyrostatic treatment in thyrotoxicosis].

The accumulation of 131J in the thyroid gland was investigate in dynamics in 31 patients with thyrotoxicosis, treated with mercaptoimidazol (timidazol) for an average of 16 months. The patients were clinically euthyroid, with normal values of the basal metabolism, PBI, PBI131 AND TOTAL THYROXIN IN SERUM. The 131J captation, investigated in the course of a maintaining treatment without discontinuation of thyrostatics, show elevated percentages (55.4 per cent by the 6th hour, 61.3 per cent by the 24th hour), being within the norm only in eight patients. Its average values are significantly lower up to the 6th month post treatment discontinuation and closrm, with only 13 above the norm. Only three of them (10 per cent) developed recidivations till the end of the 9th month after e treatment. The authors concluded that thyrostatics, in maintaining doses, do not block thyroid gland 131J cumulation which in the majority of the cases persisted to be elevated a long time after the discontinuation. Its complete normalization in the later stages speak, most probably, for the development of a lasting remission of thyrotoxicosis.
