Two lactating women who had complained of back pain developed spontaneous vertebral fractures with low bone mineral density (BMD) several months postpartum. The back pain and biochemical abnormalities presented as hypercalcemia and elevated plasma levels of the parathyroid hormone-related protein (PTH-rP) that returned to normal indices with increasing BMD after weaning. The increased circulating PTH-rP might contribute to the pregnancy-associated osteoporosis in women who probably are already osteopenic.

A 52-year-old woman complained of lower back pain and gluteal pain in April 1997, and was found to have anemia, hypercalcemia and renal disorder. In September of the same year, she was diagnosed as having IgA-lambda myeloma (stage IIIA). VMMD-IFN therapy was started in November, 1997, and this resulted in improvement of the M-protein level, and relief of the pain in the lower back and gluteal region. A second course of VMMD-IFN therapy was also effective. In April 1998, however, the back pain worsened, and in July the patient suffered a fall and fractured her left femur. Upon readmission to our hospital, the level of M-protein was lower, and high fever, hypercalcemia, renal disorder, elevation of the LDH level, anemia and thrombocytopenia were observed. Bone marrow examination revealed 30% atypical large-sized CD19-, CD38+, CD56+ myeloma cells and chromosomal abnormalities. Although the symptoms were improved temporarily after a third course of VMMD therapy, disease aggravation occurred again, and extramedullary masses appeared on the head, face and pelvis. VAD therapy was performed without effect, and the patient died about 2 months after recurrence. This was a comparatively rare case of fulminant multiple myeloma occurring in the terminal stage.

Case 1: A 43-year-old woman underwent mastectomy because of locally advanced breast cancer with multiple bone metastases. She was treated with CMF therapy but developed a compression fracture of a thoracic vertebra after 10 months and received pamidronate therapy. Pamidronate administration relived her back pain after 2 months and she was able to walk again after 3 months. However, she developed a resistance to the treatment, and then refused another treatment. She was found to have hypercalcemia 6 months later and received pamidronate again, but died 9 months after the treatment. Case 2: A 52-year-old woman underwent mastectomy because of breast cancer (T2) and was diagnosed as having multiple bone metastases 24 months after the operation. She could not turn over in bed due to progressing bone pain and received pamidronate therapy with CMF therapy at home 23 months after the diagnosis. After 2 months, pamidronate administration relieved her bone pain and she was free of pain after 4 months. After 5 months, X-rays revealed that lytic lesions showed sclerosis, and the pamidronate therapy was assessed as producing a PR. Pamidronate therapy improved her quality of life and activities of daily living, and she continues to receive it this time as an outpatient. Pamidronate therapy is promising as an effective treatment for bedridden patients with bone metastasis from breast cancer.

We thoracoscopically managed parathyroid adenoma of the upper anterior mediastinum in a 29-year-old man. He had a backache and was found to have bilateral ureteric stones, hypercalcemia, and extremely increased parathyroid hormone levels. 99mTc-methoxyisobutyl isonitrile scintigraphy showed an accumulation area projected onto the right thyroid lobe and the upper mediastinum. A diagnosis of primary hyperparathyroidism secondary to double adenomas was made. The patient then underwent surgical intervention. With the patient under general anesthesia with one-lung ventilation, a reddish brown adenoma of an upper mediastinum was removed thoracoscopically with three trocars, whereas the right superior parathyroid adenoma was excised by a standard open cervical procedure. Conventionally, the mediastinal parathyroid adenoma was removed by an open approach and was associated with perioperative distress to the patient. If the exact location of the mediastinal lesion is established, thoracoscopic excision of these lesions is feasible and is strongly recommended.

A 45-year-old man with chronic myelogenous leukemia (CML) in the accelerated phase was admitted to our hospital because of lower back pain and hypercalcemia. On admission, he was confused and found to have massive splenomegaly. The hypercalcemia and splenomegaly improved significantly after administration of incadronate, hydroxyurea, vincristine and prednisolone. Splenomegaly recurred after cessation of the chemotherapy, and examination of the peripheral blood showed 31% blasts, positive for both CD13 and CD33, on which basis myeloid blastic transformation was diagnosed. Vindesine, cytarabine and prednisolone were administered, and the splenomegaly improved again. On admission, when the patient's serum calcium level was 16.0 mg/dl, his serum parathyroid hormone-related protein (PTHrP) level was elevated to 118.3 pmol/l. Furthermore, RT-PCR analysis revealed that the patient's CML cells expressed PTHrP mRNA, and a high level of PTHrP was detected in the supernatant of cultured mononuclear cells derived from the patient's peripheral blood. These findings indicated that the hypercalcemia was due to production of PTHrP by the leukemic cells. Several cases of PTHrP. mediated hypercalcemia associated with CML have been reported previously, and are reviewed here.

Nonsecretory multiple myeloma (NSMM) is a rare variant of the classic form of multiple myeloma (MM) and accounts for 1% to 5% of all cases of MM. The clinical presentation and radiographic findings of NSMM and MM are the same. The diagnosis of MM requires the detection of a monoclonal gammopathy in the serum or urine. In NSMM, however, no such gammopathy can be demonstrated, making the diagnosis more difficult. We describe a 43-year-old African American woman who initially had back pain and pathologic vertebral compression fractures that were thought to be due to osteoporosis. Five months later, hypercalcemia developed and NSMM was diagnosed. No monoclonal gammopathy was found in the serum or urine, but skeletal survey showed diffuse osteolytic lesions, and bone marrow biopsy revealed marked plasmacytosis. The immunohistochemical techniques and chromosomal analysis methods that are currently available are discussed.

A 75-yr-old male simultaneously having lymphoplasmacytic lymphoma (LPL) and diffuse large B-cell lymphoma (DLBCL) is presented. He had manifested with lumbago, high-grade fever, and confusion. Physical examination on admission showed disorientation and severe back pain. There were neither lymphadenopathy nor hepatosplenomegaly. Routine laboratory tests showed moderate pancytopenia, hypercalcemia (serum calcium, 15.9 mg/dL), IgM lambda-type monoclonal gammopathy (IgG, 405 mg/dL; IgA, 42 mg/dL; and IgM, 2023 mg/dL), and lambda-type Bence-Jones protein in the urine (0.8 g/d). Bone marrow biopsy showed the clusters of surface lambda-positive small-sized mature-appearing lymphoplasmacytoid cells. Bone survey and computed tomographic scan showed multiple osteolytic lesions and a tumor involving the third lumbar spine (L3). An open biopsy of the L3 tumor showed diffuse proliferation of CD20- and lambda-positive large cells. We thus diagnosed the patient as simultaneously having LPL and DLBCL. Although the combination chemotherapy was at least partially effective, he died of bacteremia and organ failure after three courses of chemotherapy. To clarify the clonal relatedness between LPL and DLBCL, we analyzed the sequences of the complementarity-determining region 3 in immunoglobulin heavy-chain genes. The data showed that LPL and DLBCL in the present patient originated from two independent clones.

Supplementation therapy with plain vitamin D plus calcium is in general regarded as effective prevention or first-step treatment of glucocorticoid-induced osteoporosis (GIOP). The aim of our study was to compare the therapeutic efficacy of the D-hormone analog alfacalcidol with plain vitamin D in patients with established GIOP with or without vertebral fractures. Patients on long-term glucocorticoid (GC) therapy were included as matched pairs to receive randomly either 1 microg alfacalcidol plus 500 mg calcium per day (group A, n=103) or 1000 IU vitamin D3 plus 500 mg calcium (group B, n=101). The two groups were well matched in terms of mean age, sex ratio, mean height and weight, daily dosage, and duration of GC therapy, and the percentages of the three underlying diseases included chronic obstructive pulmonary disease, rheumatoid arthritis, and polymyalgia rheumatica. The baseline mean bone mineral density (BMD) values at the lumbar spine for the two groups were -3.26 (alfacalcidol) and -3.25 (vitamin D(3)) and, at the femoral neck, -2.81 and -2.84, respectively (T scores). Rates of prevalent vertebral and nonvertebral fractures did not differ between groups. During the 3-year study, we observed a median percentage increase of BMD at the lumbar spine of 2.4% in group A and a loss of 0.8% in group B ( P<0.0001). There also was a larger median increase at the femoral neck in group A (1.2%) than in group B (0.8%) ( P<0.006). The 3-year rates of patients with at least one new vertebral fracture were 9.7% among those assigned to the alfacalcidol group and 24.8% in the vitamin D group (risk reduction 0.61, 95% CI 0.24-0.81, P=0.005). The 3-year rates of patients with at least one new nonvertebral fracture were 15% in the alfacalcidol group and 25% in the vitamin D group (risk reduction 0.41, 95% CI 0.06-0.68, P=0.081). The 3-year rates of patients with at least one new fracture of any kind were 19.4% among those treated with alfacalcidol and 40.65% with vitamin D (risk reduction 0.52, 95% CI 0.25-0.71, P=0.001). In accordance with the observed fracture rates, the alfacalcidol group showed a substantially larger decrease in back pain than the plain vitamin D group ( P<0.0001). Generally, side effects in both groups were mild, and only three patients in the alfacalcidol group and two in the vitamin D group had moderate hypercalcemia. We conclude that alfacalcidol plus calcium is highly superior to plain vitamin D3 plus calcium in the treatment of established GIOP.

A 76 year old lady presented with altered sensorium and was found to have hyperammonemia on evaluation. She had no evidence of liver disease. For her symptomatology of backache, evaluation by bone marrow study showed evidence of multiple myeloma. She was given chemotherapy for multiple myeloma, which resulted in improvement in her sensorium, along with this there was also a rapid decline in serum ammonia levels. Hyperviscosity and hypercalcemia are common causes of altered sensorium in a patient with myeloma but in this case hyperammonemia was the likely cause.

In postmenopausal osteoporosis, the administration of alfacalcidol to women resulted in an increase in trabecular bone mineral density (BMD), prevention of cortical bone loss, and a significant reduction in the incidence of further vertebral fractures. There is now robust evidence that alfacalcidol may be particularly active in conditions characterized by an increased rate of bone loss. Alfacalcidol 1 microg/day fully prevented vertebral bone loss over 3 years in women after the first year of menopause. In a large cohort of individuals starting treatment with high dose corticosteroid (CS, 46.6 mg equivalent prednisolone per day), the spinal bone loss observed in untreated patients was fully prevented by administration of 1 microg/day alfacalcidol. In patients with established CS-induced osteoporosis, with or without prevalent vertebral fractures, 1 microg/day of alfacalcidol, given for 3 years, increased lumbar spine density, reduced back pain, and showed a significant reduction in the rate of new vertebral fractures, compared to native vitamin D. In cardiac transplant recipients, alfacalcidol and calcium reduced spinal and femoral bone loss, compared to a control group treated with etidronate and calcium. Alfacalcidol-treated patients experienced fewer new vertebral fractures over the 2-year followup. When alfacalcidol and vitamin D3 were compared in elderly women with radiologic evidence of vertebral fracture, fractional calcium absorption was increased after 3 months with alfacalcidol but was unchanged with vitamin D3. In a recent metaanalysis of 14 studies of native vitamin D and 19 studies of D-hormone analogs (alfacalcidol and calcitriol), the D-analogs exerted a higher preventive effect on bone loss and fracture rates in patients with no exposure to CS. In head-to-head studies comparing D-analogs and native vitamin D in patients receiving CS, this metaanalysis identified significant effects favoring D-analogs for femoral neck BMD and spinal fractures. In conclusion, improvement in bone turnover, increase in BMD, and reduction in fracture rates have been described during alfacalcidol treatment in situations characterized by a high rate of bone loss, including CS-induced osteoporosis, early postmenopausal bone loss, and organ transplant. Compared to plain vitamin D, alfacalcidol exerts higher bone-protective effects, thus allowing the doses to be minimized and lowering the risk of adverse effects, including hypercalcemia.
