Radiological sacroiliac (SI) changes were found in 3 patients, 2 with primary hyperparathyroidism (1 also with associated chondrocalcinosis) and 1 with osteomalacia. Osteomalacia was due to celiac disease. None of the 3 patients, all females, had a history of psoriasis, urethritis, iritis or chronic colitis. There was no renal function impairment. Peripheral joints were affected in the patient with associated condrocalcinosis. HLA B 27 was negative in all cases. Low back pain and vertebral stiffness were present in the patient with osteomalacia. A dramatic improvement in pain and stiffness ensued after vitamin D injections. These SI lesions, which may simulate ankylosing spondylitis, were attributable to subchondral bone changes related to the metabolic bone diseases. In the case of osteomalacia the SI lesions were predominantly on the right side, where there was a Looser's zone on the ischial ramus suggesting that pseudofractures could be a cause of SI changes. Metabolic osseous diseases such as osteomalacia or primary hyperparathyroidism should be investigated in cases of HLA B 27 negative radiological "sacroiliitis".

Patients with primary hyperparathyroidism are often elderly with cardiovascular disease and in some an operation might be hazardous owing to anaesthetic complications. A technique for operation for primary hyperparathyroidism under local anaesthesia is described. The method uses a unilateral approach. Seventeen consecutive patients operated on under local anaesthesia were compared with a group of 15 patients undergoing surgery under general anaesthesia. Normocalcaemia was achieved in 14 patients in each group. There was no difference in the extent of pain or the overall well-being between the two groups as determined by a visual analogue scale. Patients receiving local anaesthesia, however, experienced significantly less nausea after operation (P < 0.01). There was more fluctuation in blood pressure and heart rate in the general anaesthesia group compared with the other group. Surgery for primary hyperparathyroidism can be performed safely under local anaesthesia, and could be offered to patients if general anaesthesia were not suitable or involved an increased perioperative risk. It should not be recommended for routine use in patients who are fit for general anaesthesia.

Persistent primary hyperparathyroidism due to mediastinal parathyroid adenoma was effectively treated by either angiographic ablation or median sternotomy in this study of 49 patients managed at the National Institutes of Health since 1977. Each patient presented here with symptomatic persistent primary hyperparathyroidism after failed initial surgical procedures done at other institutions. Each patient underwent extensive parathyroid localization procedures, including selective angiography, and most had a parathyroid adenoma localized to the mediastinum. Angiographic ablation, the deliberate injection of large doses of contrast material into the artery that selectively perfuses the adenoma, was initially successful in 22 of 30 procedures (73%) in 27 patients. Long-term control of persistent primary hyperparathyroidism was achieved in 17 of 27 patients (63%) by angiographic ablation. Each unsuccessful ablation could be easily salvaged by surgical resection. Surgical resection of the parathyroid adenoma by median sternotomy achieved immediate success in 24 of 24 procedures (p2 less than 0.02 versus ablation), and long-term cure in 23 of 23 evaluable patients (p2 less than 0.001 versus ablation). However, ablation did have benefits for the patients in whom it was successfully performed. It was associated with a significantly shorter hospital stay (median, 6 days versus 9 days for sternotomy, p2 less than 0.003), much less pain, and easier recuperation. Complications of each procedure were transient and similar in both groups. Operative resection is the most effective single means to eradicate mediastinal parathyroid adenoma; however, angiographic ablation can provide similar long-term control of hyperparathyroidism in 63% of patients with less pain and shorter convalescence than that seen in patients after median sternotomy. Our results suggest that angiographic ablation should be attempted as the initial procedure for patients with persistent primary hyperparathyroidism caused by an angiographically identified mediastinal parathyroid adenoma. Operation can be reserved for those who fail ablation.

Two cases of acute attack of pseudogout associated with primary hyperparathyroidism are reported. Case 1 suffered from acute pain and swelling of the right ankle and dorsal of the right foot. Case 2 suffered from unknown fever and pain of the bilateral jaw, shoulder, elbow, wrist and knee joints. Postoperative radiological studies revealed the association of chondrocalcinosis in both cases. Synovial fluid in case 2 was aspirated and analyzed for calcium pyrophosphate dihydrate crystal by microscopic examination.

A patient with long-standing, asymptomatic, primary hyperparathyroidism developed pain in the anterior neck area, with cough, dysphagia and increasing shortness of breath. This led to respiratory insufficiency, which required endotracheal intubation and respirator assistance. During the ensuing hours the patient developed an area of ecchymosis on the anterior chest. Chest x-ray showed widening of the superior mediastinum, and CT scan showed a large mass with a fluid level. Surgery revealed a large hematoma originating from a mediastinal parathyroid adenoma with a hemorrhagic infarct. Serum calcium, previously elevated, decreased to normal with the onset of neck pain, and the patient remains normocalcemic. Previous reported cases of this rare complication of parathyroid adenomas are reviewed. Hemorrhagic infarct of a parathyroid adenoma may present with a rapidly enlarging mediastinal mass, and/or hypercalcemic crisis. Surgical removal of the infarcted adenoma can return the serum calcium to normal.

A 9-year-old boy, who had been admitted to the Pediatric Department for the examination of IgA nephropathy, was transferred to our urological clinic on Aug. 6, 1985, because of parathyroid crisis. Before urological consultation, he had been complaining of bilateral knee and calcaneal pain, anorexia and abdominal pain, which had persisted for several days. Laboratory data indicated serum Ca of 17.6 mg/dl, iP of 2.3 mg/dl and iPTH of 0.77 ng/ml. Roentgenographic examination such as chest, extremities and neck computed tomography showed no abnormal findings. The final diagnosis was parathyroid crisis caused by primary hyperparathyroidism and neck exploration was carried out on August. 10. Left upper parathyroid gland, which was 1 cm in diameter, was surgically removed. The other three glands were normal in size. Histological examination of the resected parathyroid gland revealed chief cell adenoma. In the post-operative course, serum Ca level was soon reduced to the normal range and bone pain disappeared rapidly. During the follow up period of 2.5 years, the patient was clinically free of recurrence. Only 23 cases of primary hyperparathyroidism in children have been reported in the Japanese literature. The clinical characteristics of these specific cases are that primary hyperparathyroidism in children shows a low incidence of renal lesion, but the complicated bone disease is of higher incidence compared with the adult cases. Histopathologically, parathyroid adenoma was frequently observed (14/19), and the other 5 cases were parathyroid hyperplasia.

The article reports a patient with skeletal pain were radionuclide skeletal images (100 MBq 99mTc-methylenediphosphonate) suggested a metastatic neoplastic lesion as the underlying cause. Further examination revealed that the patient suffered from normocalcemic primary hyperparathyroidism, and after removal of an adenoma of the parathyroid gland the images normalised and the skeletal pain disappeared.

For years, brown tumors have been considered to be a characteristic of primary hyperparathyroidism. However, since 1963 several reports indicate the incidence of brown tumors in patients with renal secondary hyperparathyroidism to be 1.5%-1.7%. The appearance of multiple brown tumor lesions is rather uncommon in secondary hyperparathyroidism which is also true for malabsorption as its cause. We report on a 56-year-old man presenting with pain in the bones and multiple osteolyses. A bone biopsy specimen and the laboratory examinations were indicative of secondary hyperparathyroidism caused by malabsorption most likely due to Billroth's II/I gastric resection. Thus, the patient's osteolyses represent brown tumors which have been induced by nutritional secondary hyperparathyroidism.

Simultaneous presentation of obstructing ureteral calculi and untreated primary hyperparathyroidism offers an interesting therapeutic dilemma. We herein review 8 cases, with 6 occurring in the last 3 years. When both conditions require surgical intervention the parathyroid adenoma should be excised first. The adenoma and offending stone can be removed at the same operation, with resultant prompt relief of pain and decrease in hospitalization.

A series of 38 cases of primary hyperparathyroidism seen at a single hospital within a four a half year period is reported. The importance of hypercalcemia in the diagnosis of this syndrome and its screening in cases of arterial hypertension, gout, osteoporosis, and families with type I multiple endocrine neoplasia are underlined. The patients in the present series had a florid clinical history with a mean duration of 14 years. Main symptoms were urolithiasis (52%), arterial hypertension (28.9%), bone involvement and pain (23.7%), and peptic ulcer (18.4%). There were a high proportion of patients with hyperuricemia (26.3%), some with classical symptoms of gout. One patient presented simultaneous pituitary and pancreatic involvement. Surgical therapy was undertaken in 25 patients, of whom 24 (96%) were cured, one of them after reoperation. There were no cases of relapse, hypoparathyroidism, or postoperative death. Surgery is the only rational and definitive form of treatment of hyperparathyroidism; both experienced surgeons and pathologists are necessary to deal with the anatomic and histologic subtleties of this interesting endocrine disorder.
