Primary hyperparathyroidism is the most common cause of hypercalcemia and 80-85% of the patients have parathyroid tumors. The purpose of this retrospective review was to analyse whether differences exist between patients with parathyroid tumors treated in the 1980s and 1990s. Between 1980-1997, 253 patients underwent initial surgical neck exploration for hyperfunctioning parathyroid tumors. Renal (polyuria, nocturia, renal colic due to lithiasis), rheumatologic (bone and joint pain), neurological (fatigue, memory loss, depression) and gastrointestinal (dyspepsia, anorexia, nausea) symptoms were recorded and main biochemical parameters were measured. In all patients one or more preoperative localization procedures were carried out prior to successful parathyroidectomy, and the confirmation of imaging findings was obtained after surgery. The patients were divided in two groups. Group A: 121 (47.8%) patients who underwent surgery from 1980-1989; Group B: 132 (52.2%) patients in whom parathyroidectomy was performed from 1990-1997. There were no differences (p=NS) between the two groups in average age, preoperative serum creatinine and intact-PTH levels. Symptoms were most common in Group A, and pre-operative serum calcium levels were significantly lower in Group B. Ultrasonography (n=191) sensitivity did not improve significantly (82.8% vs 82.9%), but positive predictive value (PPV) was higher (89.8% vs 96.0%). CT-scan (n=73) sensitivity was 79.2% and 82.6%, and PPV was 95.0% and 100% in Groups A and B, respectively. 201Tl/99mTc subtraction scintigraphy (n=111, Group A) was 84.6% sensitive (PPV=92.6%) whereas 99mTc-sestamibi scanning (n=90, Group B) was 85.1% sensitive (PPV=96.1%). In conclusion, the clinical features of parathyroid tumors has changed in the nineties and increasing asymptomatic pHPT rate has been found. Although sensitivity and PPV of preoperative localization procedures has improved moderately, at present noninvasive techniques may offer excellent results and should be used in all patients with suspected parathyroid tumors.

A 13-year-old castrated domestic shorthair cat was examined because of fever, anorexia, and dermatologic lesions. Crusting, erythema, and well-demarcated purple discoloration of the foot pads and the tips of the pinnae, nose, and tail were seen. A white flocculent precipitate was detected in cooled serum. This precipitate dissolved upon rewarming, consistent with a cryoglobulin. Hypercalcemia, high alanine and aspartate aminotransferase activities, thrombocytopenia, and a monoclonal IgG gammopathy were found. Numerous hepatic nodules were detected by means of abdominal ultrasonography. Cytologic evaluation of fine-needle aspirates of the liver and spleen revealed numerous plasma cells, and evaluation of a bone marrow aspirate revealed plasmacytosis. A diagnosis of multiple myeloma and monoclonal IgG cryoglobulinemia was made, and the cat was euthanatized.

In the medical environment, information disclosure to patients and respect of autonomy have spread rapidly. Today, many terminally-ill cancer patients wish to spend as much time at home as possible. In such situations the patient who has been informed that curative treatments are no longer expected to be beneficial can now hope to receive home care and visiting care from hospice/palliative care services. The essential concepts of hospice/palliative care are symptom management, communication, family care and a multidisciplinary approach. These concepts are also important in the outpatient department. In particular, medical staff need to understand and utilize management strategies for common symptoms from which terminally-ill cancer patients suffer (ex. cancer pain, anorexia/fatigue, dyspnea, nausea/vomiting, constipation, hypercalcemia and psychological symptoms). They also need to know how to use continuous subcutaneous infusion for symptom management in the patients last few days. The present paper explains the clinical practices of hospice/palliative care in the outpatient department. Also discussed is support of individual lives so that maximum QOL is provided for patients kept at home.

A 57-year-old male patient, recently known with an anal carcinoma with inguinal lymph node involvement, was admitted because of anorexia, nausea, vomiting and constipation. On physical examination the patient was dehydrated, and a systolic murmur, grade III/VI, punctum maximum apex cordis, was heard. Serum calcium was raised (4.50 mmol/l), as was the serum creatinine (328 mumol/l). Both values had been normal 14 days before admission. Serum parathormone was suppressed. A bone scan did not reveal evident lesions in the skeleton. FDG-PET scan showed uptake of the tracer into the bone marrow. A bone biopsy showed metastasis of a squamous cell carcinoma. Shortly after that the patient died. Hypercalcaemia is associated with cancer. Colorectal/anal carcinomas have a low incidence of hypercalcaemia. The prognosis of patients with cancer associated with hypercalcaemia is poor.

Unexplained hypercalcemia has been increasingly recognized in cats since 1990. In some instances, hypercalcemia has been associated with calcium oxalate urolithiasis, and some affected cats have been fed acidifying diets. We studied the laboratory findings, clinical course, and treatment of 20 cats with idiopathic hypercalcemia. Eight (40%) of the cats were longhaired and all 14 cats for which adequate dietary history was available had been fed acidifying diets. Clinical signs included vomiting (6 cats), weight loss (4 cats), dysuria (4 cats), anorexia (3 cats), and inappropriate urinations (3 cats). Hypercalcemia was mild to moderate in severity. and serum parathyroid hormone concentrations were normal or low. Serum concentrations of phosphorus, parathyroid hormone-related peptide, 25-hydroxycholecalciferol, and calcitriol were within the reference range in most cats. Diseases commonly associated with hypercalcemia (eg, neoplasia, primary hyperparathyroidism) were not identified despite thorough medical evaluations and long-term clinical follow-up. Azotemia either did not develop (10 cats) or developed after the onset of hypercalcemia (3 cats), suggesting that renal failure was not the cause of hypercalcemia in affected cats. Seven of 20 cats (35%) had urolithiasis, and in 2 cats uroliths were composed of calcium oxalate. Subtotal parathyroidectomy in 2 cats and dietary modification in 11 cats did not result in resolution of hypercalcemia. Treatment with prednisone resulted in complete resolution of hypercalcemia in 4 cats.

A 76-year-old man presented with a subacute history of weight loss, malaise and anorexia. Laboratory investigations revealed serially increasing hypercalcaemia, correlating with deterioration in his clinical status. He was subsequently shown to have hypocortisolaemia, which improved with the administration of intravenous steroids. Subsequent biochemical testing revealed the endocrinological defect to be one of isolated ACTH deficiency, which, unlike Addison's disease, does not classically include hypercalcaemia in its presentation.

An 86-year-old woman presented with anorexia, thirst and nycturia. Laboratory results revealed a hypercalcaemia with renal failure. The patient used 1-6 vitamin A-D tablets daily (1 tablet contains 600 IU retinol palmitate and 200 IU cholecalciferol). The diagnosis was: hypercalcaemia due to chronic vitamin A ingestion. This diagnosis was supported by the finding of the elevated vitamin A concentration in the patient's serum and the exclusion of other causes of hypercalcaemia. In chronic vitamin A ingestion risk factors for vitamin A toxicity are age, body weight and renal insufficiency. The hypercalcaemia caused by chronic vitamin A ingestion is explained through the up-regulation of osteoclasts by retinol metabolites.

A 48-year-old male patient from Surinam presented with anorexia, nausea and weight loss. An extreme hypercalcaemia of 5.08 mmol/l was found. Further diagnostic investigations showed that this patient had a HTLV-1 positive adult T-cell leukaemia/lymphoma (ATL/L). This is often associated with multilobularly nucleated lymphocytes, bone destruction and hypercalcaemia. Skin localisations are frequently observed. The combination of cytomorphology, immunophenotyping, HTLV-1 seropositivity and clinical findings points to the diagnosis. The patient was treated with 6 courses of chemotherapy consisting of cyclophosphamide, doxorubicin, teniposide, prednisone, vincristine and bleomycin. Upon inquiry it appeared that he had died elsewhere. Chemotherapy induces a short-lived remission in a minority of ATL/L patients. Antiviral therapy (alpha interferon, zidovudine) might offer new possibilities.

Hypercalcemia is a well-known manifestation of paraneoplastic syndromes associated with a variety of malignancies. However, colon cancer has only rarely been associated with hypercalcemia of malignancy. We present the case of a patient with recurrent adenosquamous carcinoma of the ascending colon found to have hypercalcemia. The patient is a 76-year-old white woman who initially presented with colon cancer in the cecum and underwent a right hemicolectomy. All lymph nodes and surgical margins were free of tumor. Pathological examination at that time revealed adenosquamous carcinoma of the colon. Eight months later she complained of dizziness, anorexia, and constipation and was found to have a calcium level of 13.6 mg/dL. CT scan revealed a mass measuring 10.5 to 12.7 cm in the right hepatic lobe, and a bone scan was normal. Her intact parathyroid hormone (PTH) level was 6 pg/mL (normal 12-72) and her PTH-related protein (PTHrP) level was 25.7 pmol/L (normal <1.3). She then underwent a hepatic resection. The serum PTH, calcium, and PTHrP levels normalized after resection. Hypercalcemia of malignancy in colon cancer is rare and has an association with adenosquamous histology. The hypercalcemia is attributed to PTHrP, and here we demonstrate this in the serum and tumor specimens. The effects of PTHrP are shown to be short-lived postoperatively. We find only 14 other cases in the literature of hypercalcemia related to a colonic neoplasm, and this is the only patient reported to be surviving. The diagnosis of a paraneoplastic syndrome mediated via PTHrP should be considered when hypercalcemia is encountered in the setting of metastatic colon carcinoma.

Two adult dogs were evaluated for hypercalcemia. Diagnostic evaluation identified elevated parathyroid hormone-related protein (PTHrP) and presumptive humoral hypercalcemia of malignancy. At necropsy, schistosomiasis was diagnosed. North American schistosomiasis is caused by Heterobilharzia americana. Clinical findings may include dermatitis, coughing, diarrhea, and anorexia. Clinicopathological findings may include hypercalcemia, hyperglobulinemia, hypoalbuminemia, anemia, and eosinophilia. Diagnosis by fecal examination is difficult. Praziquantel or fenbendazole treatment may be curative or palliative. These are the first reported cases of hypercalcemia with elevated PTHrP in animals without diagnosed malignancy. Elevation of PTHrP has not been previously reported in hypercalcemic humans or in animals with granulomatous inflammation.
