Careful examination as well as biochemical and hormonal investigations should be performed in men suffering from vertebral crush fractures, in order to detect a destructive skeletal process (multiple myeloma, bone metastatic lesions, lympho and myeloproliferative disorders), a mineralization defect (osteomalacia) or a secondary osteoporosis: primary hyperparathyroidism, hypogonadism, hyperthyroidism, renal hypercalciuria, alcoholism and tobacco smoking. The diagnosis of idiopathic osteoporosis should be made only after these causes have been excluded; the pathogenesis of the disease is unclear but risk factors have been identified: family history of osteoporosis, low dietary calcium intake, delayed puberty, ethanol use, tobacco smoking, inactive lifestyle and lean body build. Correction of risk factors, calcium supplementation, regular program of weight bearing physical activity, in some instances correction of testosterone deficiency may be of benefit to reduce bone loss. Severe osteopenia or osteoporosis may require sodium fluoride therapy.

Coeliac disease is a gluten-sensitive enteropathy of varying severity. Osteomalacia and hypocalcaemia can result from malabsorption of vitamin D and calcium, which, in turn, can lead to secondary hyperparathyroidism. If coeliac disease remains untreated for long, tertiary hyperparathyroidism can also develop through autonomy of the parathyroid glands via chronic stimulation. Primary hyperparathyroidism also has been reported in some cases of coeliac disease. We report the case of an adolescent with coeliac disease presenting with severe hypercalcaemia from a parathyroid adenoma. A 14 year-old girl was admitted to our department for delayed puberty and growth retardation. Laboratory examination revealed iron deficiency anaemia, low 25OH vitamin D level (7 ng/ml), high parathyroid hormone level (PTH) (955 pg/ml), and hypercalcaemia (13.4 mg/dl). Endoscopic biopsy was compatible with gluten enteropathy. Endomysium antibody was positive. A gluten-free diet was started. Her calcium returned to normal after excision of the parathyroid adenoma. After four months of the gluten-free diet, she began to mature, and puberty began with development of breasts and axillary-pubic hair growth. It has been suggested that autonomous four-gland hyperplasia or tertiary hyperparathyroidism may progress to adenoma formation, and that this should be termed "quaternary hyperparathyroidism". More studies are required to explain the relationship between coeliac disease and hyperparathyroidism.
