This article report a study of 23 cases of hypercalcemia crisis resulting from primary hyperparathyroidism (18 cases), carcinoma (4 cases) and vitamin D intoxication (1 case). In addition to the symptoms of primary diseases, the patients with hypercalcemia crisis often had anorexia, nausea, vomiting, polydipsia, polyuria, psychoneurotic symptoms, arrhthmia. The severity of the symptoms was proportional to the degree of hypercalcimia. Serum calcium concentration of patients in hypercalcemia crisis should be equal or higher than 3.75 mmol/L (15 mg/dl) or serum ionized calcium higher than 1.88 mmol/L. Treatment hypercalcemia crisis consisted of rapidly lowering the serum calcium level by various measures while actively treating the primary diseases. Our experience is to supply normal saline intravenously or orally to increase the extracellular fluid and to enhance excretion of the urine calcium by administrating furosemide. In this paper, serum calcium concentration of 5 patients with hypercalcemia crisis treated with salmen calcitonin was reduced in varying degrees. The above mentioned treatment would be beneficial to the alleviation of the crisis and the preparation for operative treatment.

A 78-year old male with ureteral carcinoma manifesting hypercalcemia is reported. He was diagnosed as having ureteral carcinoma of the left side 2 years previously and was treated by nephrectomy with ureterovesicostomy. In October 1991, he was admitted for anorexia. A clinical examination revealed recurrence of the ureteral carcinoma with metastasis to the rectum and liver. His serum calcium level was elevated (13.9 mg/dl). In addition to rehydration and furosemide, treatment with eel-calcitonin and prednisolone failed to decrease his serum calcium level. Finally, he was administered mithramycin but he died 13 days later. He had no evidence of bone metastasis or hyperparathyroidism. Nephrogenic cAMP and urinary parathyroid hormone-related protein (PTHrP) were markedly elevated. Immunohistochemical study demonstrated expression of PTHrP in the tumor cells. Thus, the hypercalcemia was thought to be mediated by PTHrP secreted from the neoplastic tumor. Although there have been several reports of ureteral carcinoma associated with humoral hypercalcemia of malignancy, this is considered to be the first case associated with elevation of PTHrP.

A 24-year-old man with anorexia, repeated bouts of vomiting, and wasting was found to have florid thyrotoxicosis and hypercalcaemia. Pamidronate promptly reduced the serum calcium concentration to normal, and simultaneously abated the abdominal symptoms, which did not recur in spite of continuing severe hyperthyroidism, which was eventually controlled by radioactive iodine ablation of thyroid activity.

In common with any medical problem, careful assessment and an analytical approach are the keystones to effective symptom control in advanced cancer. When dealing with such symptoms the multi-faceted pathophysiology must be considered, and due attention paid to the affective component of pain and other symptoms. Adequate care given to history taking and a knowledge of the likely pathogenesis of symptoms in advanced cancer can prevent unnecessary investigations and fruitless trials of inappropriate symptomatic remedies. The treatment chosen should be the simplest effective regimen tailored to the individual patient. The importance of explanation to the patient cannot be overstated and is an integral part of any treatment and the sole component of many. This paper reviews the management of common symptoms in advanced cancer (dyspnoea, nausea and vomiting, constipation, anorexia-cachexia syndrome, hypercalcaemia, confusion, insomnia and depression.

We described a case of adult T cell leukemia (ATL) not associated with human T-cell leukemia virus type I (HTLV-I), a clinical entity that was first reported by Shimoyama et al. A 79-year-old male was admitted with anorexia and fever in October, 1989. Physical examination revealed marked hepatosplenomegaly and superficial lymphadenopathies. Hematological examination revealed marked leukocytosis (136,300/microliters) with abnormal lymphoid cells showing highly lobulated nuclei. Hypercalcemia (11.2 mg/dl) and elevation of lactic dehydrogenase were also recognized. Surface marker analysis showed that the abnormal lymphoid cells in the peripheral blood were positive for CD2 and CD4 but negative for CD8. Southern blot analysis of the DNA from peripheral blood leukemic cells revealed monoclonal rearrangement of T-cell receptor beta-chain gene. The clinical and hematological findings of the patient were compatible with those of acute type ATL, however, serum anti-HTLV-I antibody was negative and HTLV-I proviral DNA was not detected in the leukemic cells by Southern blot analysis. Furthermore, the polymerase chain reaction showed no integration of the HTLV-I proviral DNA in the leukemic cells.

Hypercalcemia is an extremely rare complication of prostatic carcinoma. It occurs mainly in patients with disseminated osseous metastases and may be corrected by bilateral orchiectomy or hormonal manipulation. Humoral factors may be involved in its pathogenesis. Its occurrence is an ominous prognostic sign. We report a case of hypercalcemia that developed in a man suffering from adenocarcinoma of the prostate and who had undergone bilateral orchiectomy. Mental confusion, anorexia, and abdominal pains were the presenting symptoms. The hypercalcemia was refractory to treatment with fluids, furosemide, steroids, and calcitonin, and responded only to mithramycin. Cessation of this medication resulted in a prompt recurrence of the hypercalcemia.

Plasma cell myelomas in horses have been reported infrequently. Data from 10 cases, 9 from the literature and 1 new case, are used to characterize the disease in the horse. Hot-blooded horses (7/10), specifically Quarter Horses (4/10), were most often affected. Median age at diagnosis was 11 years (range, 3 mo-22 yr) and both male (5) and female horses (5) were represented equally. Clinical findings included weight loss (6/8), anorexia (4/8), fever (4/8), limb edema (4/8), pneumonia (3/8), rear leg paresis/ataxia (3/8), epistaxis (3/8), palpable lymphadenopathy (2/8), and bone pain (2/8). Anemia (8/8) was present routinely, and in three horses, RBCs were macrocytic. Leukopenia (2/8), thrombocytopenia (2/8), and circulating plasma cells (3/8) were variable findings. Except for abnormal protein concentrations and hyponatremia (3), abnormal results from serum biochemical analysis including hypocholesterolemia (1), hypercalcemia (1), and azotemia (1) were reported infrequently. Hyperproteinemia (8/9), hypoalbuminemia (7/9), and hyperglobulinemia (8/9) were characteristic but not invariable findings. Monoclonal proteins (7/7) were detected in the alpha 2, beta, or gamma region by serum electrophoresis. The paraprotein's heavy chain, determined in four horses, was a subclass of IgG. Three horses had decreased concentrations of normal immunoglobulins. Variable proteinuria (trace to 4+) was detected by routine urinalysis in four of six horses. Bence Jones proteinuria was detected in one of five horses (heat precipitation) and monoclonal proteins were detected in two of three electrophoresed urine samples. Three of the horses had lytic bone lesions detected radiographically. Bone marrow aspirates were diagnostic in two of five horses.(ABSTRACT TRUNCATED AT 250 WORDS)

Feeding problems, anorexia and vomiting are common in infants and children with chronic renal failure (CRF), and play a major role in the growth failure often found in this condition. However, the gastroenterological and nutritional aspects of CRF in children have received little attention, hence therapeutic interventions are usually empirical and often ineffective. Gastritis, duodenitis and peptic ulcer are often found in adults with CRF on regular haemodialysis and following renal transplantation. Despite persistent hypergastrinaemia, gastric acid secretion is decreased rather than increased in most of these patients, and active peptic disease appears to be promoted by the removal of the acid output inhibition (neutralisation of gastric acid by ammonia) that follows active treatment. Helicobacter pylori, on the other hand, does not seem to play a significant role in the pathogenesis of peptic disease in CRF. Gastro-oesophageal reflux has been found in about 70% of infants and children with CRF suffering from vomiting and feeding problems, and thus appears to be a major problem in these patients. In a number of symptomatic patients with CRF, gastric dysrhythmias and delayed gastric emptying have also been found; hence there appears to be a complex disorder of gastrointestinal motility in CRF. Serum levels of several polypeptide hormones involved in the modulation of gastrointestinal motility [e.g. gastrin, cholecystokinin (CCK), neurotensin] and the regulation of hunger and satiety (e.g. glucagon, CCK) are significantly raised as a consequence of renal insufficiency, and can be reverted to normal by renal transplantation. Furthermore, several other humoral abnormalities (e.g. hypercalcaemia, hypokalaemia, acidosis, etc.) are not uncommon in CRF. By directly affecting the smooth muscle of the gut or stimulating particular areas within the central nervous system, all these humoral alterations may well play a major role in the gastrointestinal dysmotility, anorexia, nausea and vomiting in patients with CRF. Specific pharmacological and nutritional interventions should thus be considered for the treatment of vomiting and feeding problems in CRF.

Chronic beryllium disease is predominantly a pulmonary granulomatosis that was originally described in 1946. Symptoms usually include dyspnea and cough. Fever, anorexia, and weight loss are common. Skin lesions are the most common extrathoracic manifestation. Granulomatous hepatitis, hypercalcemia, and kidney stones can also occur. Radiographic and physiologic abnormalities are similar to those in sarcoidosis. While traditionally the pathologic changes included granulomas and cellular interstitial changes, the hallmark of the disease today is the well-formed granuloma. Immunologic studies have demonstrated a cell-mediated response to beryllium that is due to an accumulation of CD4+ T cells at the site of disease activity. Diagnosis depends on the demonstration of pathologic changes (i.e., granuloma) and evidence that the granuloma was caused by a hypersensitivity to beryllium (i.e., positive lung proliferative response to beryllium). Using these criteria, the diagnosis of chronic beryllium disease can now be made before the onset of clinical symptoms. Whether, with early diagnosis, the natural course of this condition will be the same as when it was traditionally diagnosed is not known. Currently, corticosteroids are used to treat patients with significant symptoms or evidence of progressive disease.

The authors present a case of disseminated tuberculosis in a patient under dialysis with endstage renal disease. Fever, nocturnal sweating, anorexia, asthenia, ascites, lymph node involvement and granulomatous involvement of the bone marrow were observed. In the twenty nine months of renal failure which preceded the beginning of the tuberculosis, serum calcium levels were normal or low-normal and there was a secondary hyperparathyroidism. During that period the patient was treated with calcium carbonate and calcitriol. At the onset of tuberculosis, serum calcium levels rose above normal. Treatment with calcium and calcitriol was withdrawn but hypercalcemia remained unchanged. Serum concentration of parathormone fell significantly. Antituberculosis drugs were started. The resolution of active tuberculosis was accompanied by normalization of serum calcium levels and by elevation above normal of serum concentration of parathormone.
