The findings of 152 patients with proven primary hyperparathyroidism are reportedmthe purpose of the analysis was to find difference between the various clinical manifestations of the disease. Furthermore the occurrence of acute hyperparathyroid crisis in our series as well as in the literature are described. 65.8% of the patients were females, 34.2% were males. The leading symptom in 98 patients (group I) were kidney stones and in 23 patients (group II) cystic bone disease. Both manifestations of the disease occurred in only 7 patients (group III) and no symptoms related to the kidneys or to the bones occurred in 24 patients (group IV). Because of the difference of the clinical manifestations the additional data were analyzed for each group separately and compared with each other. There was no difference in the mean serum calcium levels for all four groups, however, patients of group I were on the average younger, the duration of the disease was longer and the weight of the parathyroid adenoma was lower compared to the other three groups, Data are presented regarding calcium excretion, phosphate clearance and tubular reabsorption of phosphate for each group. At operation single or multiple adenoma formation was present in 133 patients, whereas diffuse hyperplasia was found in 17 and carcinoma in 2 other patients. 46 of the adenomas were found in an atypical anatomical localisation. This observation is responsible for the many unsuccessful or second explorations of the neck; The weight of the adenomas varied between 0.1 and 23.5 g. The most difficult diagnosis was that of diffuse hyperplasia. The sucess of the surgical intervention was usually established in over 80% of the cases within 24 to 48 hours after the operation with a significant fall of serum calcium. There ist still no definite explanation for the variability of the clinical manifestations of primary hyperparathyroidism. Parathyroid hormone determinations on larger numbers of patients are not yet published. The assumption, that different hormones or peptide fragments are reposible for the different action on bone and kidney is discussed; In our series of 152 patients acute hyperparathyroid crisis occurred eight times. Our findings are compared to the other well documented cases in the literature. Main symptoms were nausea, vomiting, abdominal pain and different states of cerebral dysfunction. Most of the patients had calcium levels over 16 mg/100 ml. Partial renal insufficiency with elevated blood urea and phosphate retention was found in over 50% of the cases. Overall mortality of all cases with acute parathyroid crisis is 52.5%. The pathogenesis of acute hyperparathyroidism and the implications of high calcium levels are discussed. According to our own experience hypercalcenia can be controlled with an intensive therapeutic program and emergency operation for acute parathyroid crisis is no longer necessary.

The effects of synthetic salmon CT, administered subcutaneously and intermittently (1 MRC U/kg/day for 15 days/month over 6 months) were investigated in 15 uremic patients on regular dialysis treatment (RDT), all presenting various degrees of osteodystrophy. Clinically, osteoarticular pain disappeared in 8 out of 10 cases; 1 patient with rib fractures had a rapid calcification of the bone fracture repair tissue. No significant changes were found in serum calcium and PTH levels. Phosphotemia showed a significant decrease within the first 20 days. The varying individual hypophosphatemic response proved to be related to the initial level of phosphatemia. The alkaline phosphatase, when increased, showed a decrease to the normal range. A significant decrease in osteoclastic hyperactivity (active resorption surface, osteoclast index) and a slight increase in osteoblastic pool (active osteoid surface) were documented. No change was noted when osteomalacia predominated. Side effects included: anorexia, nausea, vomiting, face flushing. Our data suggest that salmon CT may be usefully employed in chronic uremic patients on RDT, when secondary hyperparathyroidism predominates.

Three cases of primary hyperparathyroidism in children are presented and the literature reviewed. Symptoms of nausea, weight loss, and personality changes are more common in children than in adults with this disease. Children may have the diagnosis delayed because of failure to consider hyperparathyroidism. Surgery has been demonstrated to be most effective in treating this condition.

The case history of a 65 year old female patient has been reported here by the authors. The patient was admitted to the Intensive Therapy Unit owing to her repeated heart pain. Later she was transferred to the Department of Medicine to establish the exact diagnosis. Prepyloric ulcer and hypertension were occurred in her history. The symptoms of her preceding as well as her recent illness were: pain in epigastric field, nausea, adynamia, weakness, polyuria, significant loss of weight, somnolence and the shortened Q--T time in electrocardiogram related to hypercalcemia syndrome. The calcium value in blood proved to be at critically high level from time to time. The possibility of the secondary hypercalcemic state was excluded by sonographic examination and the elevated level of parathormone in blood established the diagnosis of the hyperparathyroidism. The surgical resection of parathyroidic adenoma yielded a complete recovery of the patient. The authors call the attention to the significance of the clinical signs in the diagnosis of the disease.

Somatic symptoms are common in patients on dialysis. Their causes are largely unknown and their therapy is unsatisfactory. To examine the relationship of psychological and clinical factors to these symptoms, 191 interviews were done in patients on hemo- and peritoneal dialysis. The severity of 8 somatic symptoms (tiredness, sleep disturbance, cramps, pruritus, headache, nausea, dyspnea, joint pain) of importance in dialysis patients was measured using previously validated scales. Indices of affect and quality of life were obtained, as was demographic, clinical and laboratory information. The severity of each symptom was significantly related to the indices of affect and quality of life. Using multiple logistic regression, poor affect score was the strongest correlate of each of the following somatic symptoms, tiredness, pruritus, sleep disturbance and cramps. It was ahead of any clinical or demographic variable and was also significantly correlated with the severity of the other symptoms. Indices of hyperparathyroidism were significantly associated with headache, joint pain, dyspnea and nausea. We conclude that the strongest correlate of common somatic symptoms in dialysis patients is affect disturbance, and that therapy aimed at improving the affect may improve the symptoms.

A patient with hypercalcemia and newly diagnosed multiple myeloma developed acute pancreatitis. Other etiologic factors for pancreatitis were excluded. Hypercalcemia secondary to hyperparathyroidism is associated with acute pancreatitis. In English literature, only one other case has been published where the hypercalcemia of multiple myeloma may have caused pancreatitis. Pancreatitis should be considered in patients with hypercalcemia and multiple myeloma who develop nausea/vomiting, and abdominal pain.

In outlining the pathology of various electrolyte metabolism abnormalities in cancer patients we considered the main clinical points between pathologies and emergency treatment. In regard to sodium (Na+) metabolism, one pathologic state that requires our attention is hypernatremia. Hypernatremia is accompanied with dehydration and is due to water loss, vomiting, diarrhea and renal insufficiency. One of the major causes of this condition is lack of the antidiuretic hormone due to intracranial metastasis of the tumor. When hypernatremia becomes severe, it is accompanied with circulatory failure, muscular asthenia, disorientation, convulsions, coma and other cerebral symptoms. Treatment consists of replenishing the water content by infusion of electrolyte solutions which should be carefully conducted after complete diagnose of the severity of the patient's pathological condition. Hyponatremia, like sick cell syndrome, is observed relatively frequently in cancer patients. When the serum Na level falls markedly, it induces cerebral edema and causes disorders of consciousness. The major treatment consists of providing both water and sodium supplements. Hyperkalemia is observed at the time of renal insufficiency, tissue lesions, vomiting, and diarrhea. When serum potassium level rises, it causes bradycardia, ventricular fibrillation, or cardiac arrest. It is important to diagnostically apprehend the severity of this condition using EKG and determining the serum K1+ level. For emergency treatment injection of calcium gluconate is very effective. Hypokalemia is often manifested by the loss of intestinal fluids due to diarrhea or during administration of diuretic agents. Clinical symptoms include neural paralysis but emergencies occur relatively infrequently. K C1 injections are used in treating this condition. Hypercalcemia is manifested in cancer patients during hyperparathyroidism. Its clinical symptoms include lassitude, tachycardia, nausea, vomiting, and renal dys-function, leading to neural symptoms in severe cases. The main treatment consists of injection of physiological saline solution and administration of calcitonin, mithramycin. Hypocalemia is manifested during renal insufficiency, lack of vitamin D, and hypothyroidism. In classic cases it causes tetanic spasms. Injection of calcium is an effective treatment but since during tetanic spasms alcalosis may easily occur, treatment should only be provided after obtaining a complete understanding of the patient's condition. The pathological conditions described above can not be said to specific to cancer but it should be kept in mind that one of their main causative factors is the involvement of mechanism which produces ectopic hormones from cancerous tissues.

To determine the frequency of gastrointestinal symptoms in primary hyperparathyroidism, we retrospectively analyzed 100 consecutive patients seen at Emory University Hospital from Jan 1, 1977 through March 1, 1979. At the time of diagnosis, 28 patients complained of nausea, 19 of vomiting, 29 of abdominal pain, and 33 of constipation. One patient presented with acute pancreatitis and 14 had ulcer disease (two gastric and 12 duodenal ulcers). Hypercalcemia increases gastric acid secretion and may account for associated ulcer disease and the ulcer-like pain in primary hyperparathyroidism. The mechanisms causing the other gastrointestinal symptoms in hypercalcemia remain to be elucidated. These symptoms abate on correction of hyperparathyroidism.

Parathyroid carcinoma is a rare cause of hyperparathyroidism (rate of occurrence of 0.5% of all parathyroid neoplasms). In this report we describe three cases of parathyroid carcinoma seen in our Institution and we analyse the clinical, diagnostic, therapeutic and pathological findings of this disease. The three patients were 14, 22 and 45 year old respectively. Familial history was negative for endocrine diseases. The laboratory and instrumental findings of thyroid and adrenal glands were negative. Predominant symptoms were in all cases weakness, lethargy, bone and muscular pain, nausea, vomiting. The two young patients presented fractures of the inferior limb and of the forearm respectively, five years and one year before the diagnosis. X-ray examination and MNR easily demonstrated the "brown tumors". In two cases a symptomatic nephrolithiasis was present. The 14 year old child presented polyuria and polydipsia. In all cases a mass was palpable in the neck (two in the right side and one in the left one). The elevated serum calcium concentration (15, 18, and 20.2 mg/dl respectively) and the elevated serum PTH (480, 651, and 680 pg/ml respectively) allowed the diagnosis of hyperparathyroidism. Ultrasound scan and thallium-technetium scanning identified in all cases a mass adjacent the thyroid. A radical resection of the malignant parathyroid gland and the ipsilateral thyroid lobe was performed in two cases, while only a resection of the involved parathyroid gland in one case. The diagnosis of parathyroid cancer was established using pathologic criteria.(ABSTRACT TRUNCATED AT 250 WORDS)
