1/95. growth hormone insufficiency in a girl with the autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy.

    Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is an inherited disease which may comprise many endocrine and non-endocrine components. GH insufficiency has not been recognised as a classical manifestation of this syndrome. We describe the case of a girl with APECED, who presented with four endocrine (hypoparathyroidism, Addison's disease, hypothyroidism, gonadal failure) and three non-endocrine components (candidiasis, ectodermal dystrophy and lichen ruber planus). In addition, growth failure was documented beginning at approximately 8 years; bone age was delayed and stimulated GH peaks after clonidine and arginine were 2.2 and 9.2 microg/l, respectively. A partial empty sella was found on a computed tomography scan of the hypothalamic-pituitary region. At 10.5 years rhGH therapy was started and height gain of 26 cm was observed after 2.7 years of treatment. puberty started at 11.2 years and menarche occurred at 12.7 years. At 13.25 years rhGH therapy was discontinued owing to frequent hypocalcemic crises; serum IGF-1 levels were persistently low in the following years (between 160 and 180 microg/l, normal range for age 250-600 microg/l). The patient attained a final height of 160.8 cm, which was appropriate for her target height. The presence of lichen ruber planus and GH insufficiency probably secondary to empty sella are two unusual findings in patients with APECED.

2/95. hypocalcemia due to spontaneous infarction of parathyroid adenoma and osteomalacia in a patient with primary hyperparathyroidism.

    A 49 year-old Japanese woman had subjected enlargement of a cervical tumor, and also suffered two bone fractures in 2 years. The cervical tumor had enlarged further in the month prior to admission, becoming warm and tender. Endocrinological examination revealed that the serum intact PTH concentration was remarkably high at 400 pg/mL despite the low serum calcium concentration, and that the serum vitamin Ds concentration was decreased. Bone roentgenograms revealed severe osteolytic changes compatible with osteitis fibrosa cystica and a pathologic fracture of the humerus. Under a diagnosis of primary hyperparathyroidism, parathyroidectomy was performed, followed by fixation surgery for the pathologic fracture. Histologically, the cervical tumor was a parathyroid chief-cell adenoma with massive necrosis, and the bone pathology by iliac bone biopsy revealed the existence of osteomalacia. She was treated with calcium, vitamins D and K2 and calcitonin after the surgery. This case is a rare condition manifesting hypocalcemia with catastrophic osteoporosis under the coexistence of spontaneous infarction of parathyroid adenoma with osteomalacia, suggesting that the clinical features of hyperparathyroidism are modified by both the autoparathyroidiectomy and the existence of osteomalacia due to vitamin d deficiency.

3/95. Hypocalcemic tetany in a toddler with undiagnosed rickets.

    A 17-month-old black girl presented to the pediatric emergency department with sudden onset of her hands and feet "drawing up." A diagnosis of vitamin d deficiency rickets with tetany was made on a history of exclusive breast-feeding, low serum calcium, phosphorus, and 25-hydroxyvitamin D levels, and bone radiographs. Nutritional rickets should be considered in the differential diagnosis of acute hypocalcemia.

4/95. Postoperative hypocalcemic tetany caused by fleet phospho-soda preparation in a patient taking alendronate sodium: report of a case.

    This case report describes a patient who was previously prescribed alendronate (Fosamax) and presented with postoperative hypophosphatemia and hypocalcemic tetany after bowel preparation with Fleet Phospho-Soda. This report suggests that patients taking bone metabolism regulators may not be able to respond appropriately to hypocalcemic stressors.

5/95. High bone mass and hypocalcaemic myopathy in a patient with idiopathic hypoparathyroidism.

    The clinical manifestations of hypoparathyroidism are mainly characterised by increased neuromuscular irritability as a consequence of hypocalcaemia. Occasionally, elevation of the muscle enzymes may mimic polymyositis. Reduced parathyroid hormone production, but also vitamin D treatment and calcium supplementation, may contribute to the increased bone mass found in patients with postsurgical hypoparathyroidism. We report the case of a 36-year-old woman with untreated idiopathic hypoparathyroidism and a high bone mass despite severe muscle impairment due to hypocalcaemic myopathy.

6/95. Recognition and management of hungry bone syndrome--a case report.

    Hungry bone syndrome (HBS) following successful parathyroid surgery is a well described phenomenon. However, few studies have clearly addressed this syndrome or looked at the outcome of perioperative management. We report a case of HBS following successful parathyroid surgery. The perioperative management is discussed and literature pertaining to this interesting case is reviewed.

7/95. A man with osteoblastic metastasis and hypocalcaemia.

    We report a case of an 80-year-old man with osteoblastic metastases from advanced carcinoma of the prostate presenting with a grand mal seizure resulting from severe hypocalcaemia. He had low serum phosphate and ionised calcium levels, elevated serum skeletal alkaline phosphatase and intact parathormone levels. 99mTc radioisotope bone scan revealed a "super bone scan" suggestive of osteomalacia. The serum 1, 25-dihydroxycholecalciferol level was unexpectedly elevated. The biochemical abnormalities persisted despite high dose calcium replacement, but improved with supraphysiological doses of 1,25 (OH)2 vitamin D3 (Rocaltrol) therapy. We hypothesise that the hypocalcaemia in this patient was due to vitamin D resistance secondary to a humoral factor secreted by the tumour.

9/95. Hyperpyrexia secondary to acute hypocalcemic status. Is there a role for calcitonin therapy in bone metabolism derangements due to anticonvulsant drugs?

    hypocalcemia, hyperparathyroidism, hypovitaminosis D, hypocalcitoninemia and decreased bone mass are side effects of several anticonvulsant drugs. Since calcitonin inhibits the mineral mobilization of bone and augments minerals bone content, combined therapy with calcitonin, calcium, vitamin-C and vitamin-D was administrated to a patient with severe anticonvulsant disturbances of bone metabolism. calcitonin hypersensitivity was evident. The symptomatology, characterized by the rare hypocalcemic hyperpyrexia, regressed after calcium infusion.

10/95. Familial idiopathic hypoparathyroidism, sensorineural deafness and renal dysplasia.

    We describe a 27-year-old woman with familial idiopathic hypoparathyroidism, bilateral sensorineural deafness and right renal aplasia. There was a family history of deafness in her father and two other family members with sensorineural deafness, one of whom had hypoparathyroidism. To our knowledge, there have been four previous reports of idiopathic hypoparathyroidism associated with sensorineural deafness and renal dysplasia. The clinical features were not identical to any of the four previous reports. Although no chromosome abnormalities were present in the patient using standard trypsin G-banding analysis, we speculate that some common genetic mutation caused hypoparathyroidism, sensorineural deafness and renal dysplasia.
