Primary hyperparathyroidism is a not uncommon disease in the elderly. A prevalence of 3% for women and 1% for men is reported in subjects aged 65 years and over. Routine serum calcium determination and parathyroid hormone radioimmuno-assay allow to make an early diagnosis in still asymptomatic subjects. In the elderly the clinical features of the disease are often aspecific presenting with psychiatric and/or neuromuscular and/or cardiovascular disorders. This report refers to a 75 year-old woman admitted to our Department with a suspicion of senile dementia. She was affected by loss of memory, hallucinations, nausea, loss of appetite, mild polydipsia and polyuria. The patient was dependent in one activity of daily living (Index of Independence in Activities of Daily Living, ADL) and partially dependent in instrumental activities of daily living (Instrumental Activities of Daily Living Scale, IADL). The Short Portable Mental Status Questionnaire (SPMSQ) and the Geriatric Depression Scale (GDS) showed mild mental impairment and mild depression. Routine biochemical screening revealed a significant hypercalcemia. Parathormon assay and parathyroid scintigram were performed to confirm the diagnosis of primary hyperparathyroidism. After treatment of dehydratation and hypercalcemia, parathyroidectomy was performed: a single parathyroid adenoma was found and removed. On discharge the patient was lucid and able to carry out all ADLs and IADLs.

A 38-year-old woman was admitted to our hospital with symptoms and signs of hypocalcemia in 1977 and a diagnosis of primary hypoparathyroidism was made with a positive Ellsworth Howard test. She was then lost to follow up until 1992 when she returned this time with symptoms and signs of hypercalcemia. An inguinal lymph node was biopsied showing non-Hodgkin's lymphoma, diffuse pleomorphic type and monoclonal integration of proviral human T-cell lymphotropic virus-1 DNA was detected in lymph node cells indicating ATLL. Serum parathyroid hormone-related peptide (PTHrP) was slightly elevated and the tumor cells were positively stained with anti-PTHrP serum. Combination chemotherapy with vincristine, adriamycin, cyclophosphamide and prednisolone was given to the patient with disappearance of the lymphadenopathy and subsequent normalization of PTHrP levels. Interestingly, the signs and symptoms of hypocalcemia reappeared after the treatment requiring replacement therapy with calcium and vitamin D.

A 14 year old girl with bilateral genu valgum of 6 years duration was brought for evaluation of primary hyperparathyroidism. She had clinical features of rickets such as frontal bossing, rachitic rosary, lumbar lordosis and fixed adduction deformity of the left leg. She had undergone osteotomy earlier for correction of these deformities without benefit. Laboratory investigations showed hypercalcaemia and hypophosphataemia, with elevated alkaline phosphatase and parathyroid hormone levels. A skeletal survey showed generalized decreased density of bone and brown tumours and, coincidentally, a right renal calculus. A computerized tomography scan of the neck and thallium-technetium subtraction scan delineated an adenoma of the left superior parathyroid gland, which was surgically removed. Parathyroid adenoma manifesting with bone deformities, especially genu valgum, is very rare in children. Early diagnosis and prompt treatment is essential to prevent such deformities.

We describe a young woman with lymphocytic hypophysitis presenting in the early post-partum period. She had selective corticotroph failure causing secondary adrenal insufficiency. At the time of presentation she had transient hyperthyroidism due to thyroiditis, and hypercalcaemia. This is the third case to be described of hypercalcaemia occurring in association with lymphocytic hypophysitis. Hypercalcaemia is not a recognized complication of other forms of pituitary failure. The two previously described cases also had selective corticotroph failure and hyperthyroidism due to thyroiditis. This pattern of presentation supports the concept that thyroid hormone action in the presence of glucocorticoid deficiency is responsible for the increased calcium efflux from bone into the circulation. Reduced renal excretion of calcium due to a reduction in calcium delivery to the glomerulus and increased proximal tubular reabsorption are also implicated in the aetiology of hypercalcaemia associated with adrenal failure.

A patient with familial benign hypercalcaemia (FBH) who developed relapsing pancreatitis is presented. She underwent distal partial pancreas resection with surgical removal of pancreatic duct stones, and a pancreaticojejunostomy. No further causes for the pancreatitis were found. The present case is remarkable since it is an example of the occurrence of pancreatitis in a previously known patient with hypercalcaemia, and it underlines the severity of the pancreatitis when it occurs in this syndrome.

A 42-year-old female patient on hemodialysis (HD) developed S. aureus endocarditis of her aortic and mitral valves following the unsuccessful antibiotic treatment of an infected vascular access. She required aortic valve replacement and repair of her mitral valve. She had been receiving HD 2-3 times per week using a standard dialysate bath. Three and one-half weeks postoperatively she developed hypercalcemia with the following peak values: total calcium (t-Ca), 13.7 mg/dL; ionized calcium (i-Ca), 1.76 mmol/L. Hemodynamic instability necessitated switching from HD to peritoneal dialysis (PD). Following 48 hours of unsuccessful treatment of hypercalcemia using Baxter 2.5 mEq/L Dianeal, zero calcium dialysate prepared by our in-hospital pharmacy was used for cycler PD. Four days later the t-Ca was 10.6 mg/dL, and i-Ca was 1.32 mmol/L. Thereafter, 2.5 mEq/L calcium Dianeal was resumed. When hypercalcemia recurred (t-Ca 12.0 mg/dL and i-Ca 1.76 mmol/L), repeat use of zero calcium dialysate returned the patient's calcium values to within normal limits (t-Ca 9.0 mg/dL, i-Ca 1.20 mmol/L) by 7 days posttreatment. The results in this patient demonstrate that in-hospital pharmacies can conveniently prepare prescription-ordered dialysate and that zero calcium dialysate is yet an additional modality available to correct hypercalcemia in PD patients.

In an attempt to stimulate bone resorption, a 10-week-old infant with malignant infantile osteopetrosis was treated with high doses of calcitriol, a potent bone resorption stimulatory agent, combined with a low calcium diet to prevent hypercalcaemia. Although calcitriol administration was initiated at this very young age, our patient did not show any clinical, radiological, or histological improvement. Despite reports of positive results of this treatment in the literature, our patient did not reveal any signs of bone resorption. She eventually died from the complications of osteopetrosis at the age of 6 months after 88 days of therapy.

We report a rare case of Turner's syndrome coexisting with thyrotoxicosis and parathyroid adenocarcinoma resulting in hyperparathyroidism. This 45-year-old female patient presented with primary amenorrhea and poor development of secondary sexual characteristics. She also experienced repeated bone fractures, and body weight loss. Multiple risk factors of osteoporosis developed simultaneously in this patient. The interesting interactive relationship of hypercalcemia between thyrotoxicosis and primary hyperparathyroidism was noted. The best choice was surgery for both cases. Calcium supplements and various hormone replacements in addition to regular investigative radionuclide scans were required.

A-52-year-old patient presented with a 2-year history of multiple myeloma, recurrent episodes of hypercalcemia, and extensive bone involvement. She developed pulmonary infiltrates, initially misdiagnosed as interstitial pneumonia. High-resolution computed tomography and bone scintiscanning indicated pulmonary calcification, which was confirmed by a transbronchial biopsy. Cytostatic treatment of multiple myeloma in combination with repetitive i.v. administration of bisphosphonates over a period of 6 months led to a significant improvement of clinical symptoms. Regression of pulmonary infiltrates was demonstrated by chest radiograph and computed tomography. There are only a few reports on pulmonary calcification in patients with multiple myeloma; the condition was associated mostly with progressive disease, kidney failure, adult respiratory distress syndrome and bad prognosis. In our patient isolated calcification of the lungs without involvement of other organ systems was successfully treated. These findings suggest that interstitial pulmonary calcinosis in multiple myeloma can be reversed by normalization of serum calcium levels using bisphosphonates combined with cytostatic treatment.

A 44 year old Japanese woman with adult T-cell leukaemia (ATL) was admitted to Kyushu University hospital to receive a course of alpha-interferon treatment. She experienced a sudden onset of hypercalcaemia and epigastric pain associated with an increase in the level of pancreatic enzymes. Her serum parathyroid hormone related protein level was above normal although her high sensitive PTH level was within the normal range. Ultrasonography and computed tomography (CT) of the abdomen showed enlargement of the pancreas with indistinct margins and massive accumulation of extrapancreatic fluid. Cullen's sign was observed. A few days after the onset of acute pancreatitis, the serum amylase level increased to 3400 IU/L, and the serum calcium level fell to 4.2 mg/dL from 13.3 mg/dl. Her fasting blood glucose level increased to 242 mg/dL. Although the first episode of pancreatitis appeared to respond to treatment, she experienced a second episode of pancreatitis accompanied by an elevation of the serum calcium level. These findings suggest that acute pancreatitis was caused by hypercalcaemia associated with ATL.
