Two boys who were immobilised with peripheral neuropathy developed hypercalcaemia. It is suggested that hypercalcaemia aggravated the muscle weakness as well as producing systemic upset. The hypercalcaemia was controlled with corticosteroids which had to be continued over several months. A satisfactory remission of the disease occurred in both cases. The hypercalcaemia was attributed to immobility in young people with rapid calcium turnover in bone.

This report describes a 31-year-old woman with evidences of selective adrenocorticotropic hormone deficiency associated with a remarkable pituitary lesion, lymphoid hypophysitis. Clinical manifestations of secondary hypocortisolism, which first appeared during the immediate postpartum period following normal pregnancy, included progressive weakness and mental aberrations, fasting hypoglycemia, transient hypercalcemia, and striking ECG changes. Sudden death resulted from cardiorespiratory collapse. Microscopic examination of the anterior pituitary disclosed focal fibrosis and extensive lymphocytic infiltrations with a marked reduction of basophils; immunostaining techniques demonstrated a selective loss of corticotropin-secreting cells. The histopathology of the pituitary and its association in this case with lymphoid thyroiditis suggest that selective damage to corticotrophs was due to an autoimmune process.

In 25 (33.8%) of 74 chronically haemodialysed patients a distinct osteopathy with bone pain, spontaneous fractures, arthralgias and weakness of the muscles due to dialysis was present. In comparison to a group without complaints the duration of the dialysis was longer by 6 months, the mineral contents of the bones was decreased in 38%, in the comparative group in 22%. A progressive demineralisation was found in 46%, in the comparative group in 20%. Hypercalcaemias under vitamin D2 caused a therapy resistance. In 1 exemplary case (type IIc, PTH 0.3 micrograms/l) in the 3rd year of dialysis a fracture of the neck of the femur took place and an endoprosthesis was implanted. There was a progressive demineralisation of about 16%. The suspicion of a typical combination with an encephalopathy due to dialysis did not confirm itself. A pseudocyst in the brain was found. The differential diagnosis to the hypercalcaemia-induced psychosis in the osteopathy due to dialysis is discussed. In a prophylactic application dihydrotachysterine proved favourable for avoidance of an osteopathy due to dialysis. Parallel to the clinical progressing of the osteopathy due to dialysis a progressive demineralisation could be demonstrated at the peripheral mineral contents of the bones. Extreme losses of minerals appeared from the 4th to the 59th month of dialysis from - 16% to - 37% and from the 22nd to the 87th month from plus 11% to minus 14% of the age-and-sex-specific normal values. Successful transplantations led to the stagnation of the progressive demineralisation, unsucessful transplantations increase them. The influence of the non-refined water for the production of dialysate by possible aluminium intoxications on the development of the osteopathy due to dialysis is discussed.

Primary hyperparathyroidism was diagnosed in two German shepherd pups from a litter of four females. Clinical signs were apparent by two weeks of age and included stunted growth, muscular weakness, and polydipsia/polyuria. Radiography revealed diffuse reduction in bone density. Both pups had marked hypercalcemia, hypophosphatemia, increased plasma immunoreactive parathyroid hormone concentrations and increased fractional clearance of inorganic phosphate in the urine. Intravenous infusion of one affected pup with calcium gluconate failed to suppress the plasma concentration of immunoreactive parathyroid hormone, suggesting autonomous secretion of parathyroid hormone. Necropsy of the other pup at eight weeks of age revealed diffuse hyperplasia of parathyroid chief cells, nodular hyperplasia of thyroid C-cells, skeletal alterations consistent with fibrous osteodystrophy, hypercalcemic nephropathy, and extensive mineralization of the lungs and gastric mucosa. The dam and sire were half sibs. One male pup from a previous litter of six had developed similar clinical signs and radiographic lesions, suggesting autosomal recessive inheritance. This is the first report of hereditary primary hyperparathyroidism in domestic animals, a disease which may be analogous to hereditary neonatal primary hyperparathyroidism in children.

The most common cause of hypoadrenocorticism in dogs is idiopathic immune-mediated destruction of the adrenal cortex. Other causes include anterior pituitary insufficiency, pituitary or adrenal neoplasia, acute withdrawal of exogenous corticosteroids, and mitotane toxicity. Females are affected more often than males; only 1 feline case has been documented. Animals 2-5 years old are most commonly affected. Clinical signs include lethargy, weakness, weight loss, anorexia, vomiting, diarrhea and bradycardia. Hematologic and biochemical changes can include eosinophilia, lymphocytosis, anemia, hyperkalemia, hyponatremia and hypercalcemia. Diagnosis is by finding negligible resting levels of plasma cortisol and no response to ACTH administration, and a serum Na:K ratio of 20:1 or less. Treatment involves restoring fluid volume, correcting acidosis, and supplementing salt and glucocorticoids. Daily oral use of prednisone at 0.05 mg/kg can safely maintain most affected dogs. Some dogs only require glucocorticoids in stressful situations. Iatrogenic secondary adrenocortical insufficiency (iatrogenic Cushing's disease) may result from a single injection of long-acting glucocorticoids or from long-term use. Clinical signs are the same as for natural hyperadrenocorticism, but endogenous cortisol release is suppressed. Treatment is gradual withdrawal of the offending glucocorticoid and elimination of the cause that initially prompted glucocorticoid therapy.

Patients with end-stage renal failure develop osteodystrophy in part due to defective production of 1,25-dihydroxycholecalciferol by the kidney. We treated eight adults with chronic renal failure and osteodystrophy with 1,25-dihydroxycholecalciferol (calcitriol) for 30-44 months. Seven of these patients were also symptomatic with bone pain and/or muscle weakness. Striking amelioration of muscle weakness occurred, and bone pain was considered to be significantly improved in four of seven patients. Hypercalcemia was noted in all the patients, necessitating a reduction in the daily dose of calcitriol to a range of 0.125 to 0.5 microgram/day. While serum alkaline phosphatase fell during therapy, serum iPTH did not show any significant change. Bone mineral content improved in four patients, though it still remained below normal. Radiographic changes of osteodystrophy showed definite improvement in only three.

50% of hospitalized medical emergency cases are cardiological and respiratory emergencies. Myocardial infarction, cardiogenic shock, ventricular arrhythmias and left ventricular failure often cause sudden death occurring within 1 or 2 hours. Therefore immediate management is necessary already in the prehospital phase of cardiovascular events. This does also apply for acute respiratory failure due to obstructive ventilatory disorders. Acute exacerbations of chronic obstructive pulmonary disease frequently are masked and may be misinterpreted as encephalopathy or alcohol withdrawal syndrome. Sedation may be dangerous. Also neuroglucopenic syndrome and hyperosmolar coma are occasionally interpreted wrongly. Thyrotoxic crisis, adrenal crisis and hypercalcemia are characterized by lethargy, mental disturbance and weakness, by dehydration, myopathy, nausea, constipation, diarrhea or tenesms or arrhythmias. In this situation of varied symptoms the most important action is to think of endocrine emergency, which may have multiple etiologies.

Hyperparathyroid crisis is a rare disease but should be suspected in acutely ill patients complaining of weakness, lethargy, nausea, vomiting, confusion and abdominal pain. Despite the variety of clinical manifestations, the syndrome forms a distinctive pattern which, in the presence of a serum calcium level greater than 16 mg/100 ml, should be recognized. The most difficult problem in diagnosis is the differentiation of hyperparathyroid crisis from ectopic parathyroid hormone-producing tumors. The disease is an endocrine emergency which requires prompt surgery after rapid correction of dehydration and hypercalcemia. The best results are achieved by removing offending parathyroid tissue within 72 hours after the onset of symptoms.

Twelve patients aged over 70 with primary hyperparathyroidism (persistent hypercalcaemia and raised serum parathyroid hormone concentrations) underwent parathyroidectomy, which was well tolerated by all. After operation serum calcium concentrations returned to normal and the commonest symptoms before operation (muscle weakness, malaise, and mild to severe dementia), although not related in severity to the degree of hypercalcaemia, improved. Mental function was greatly improved. The findings suggest that primary hyperparathyroidism should be sought in any elderly patient with hypercalcaemia and that more such patients with the diagnosis should be considered for parathyroidectomy irrespective of age.

Corticosteroids are frequently prescribed in terminal cancer. They were prescribed in more than 50% of 100 consecutive patients of our hospice for palliation of anorexia, weakness, symptoms of cerebral metastases and of hypercalcemia, and other problems. There was objective and/or subjective improvement in most, though usually of short duration. If there is no improvement after a few days, corticosteroids should be discontinued.
