Hypercalcemia and osteolytic bone lesion are important complications in the prognosis of patients with adult T cell leukemia/lymphoma (ATL). We report a 61-year-old Japanese woman who died of ATL and had multiple osteolytic lesions and pathological fractures of her extremities. Highly increased serum levels of Interleukin-6 (IL-6) and a parathyroid hormone-related protein (PTHrP) together with a high level of serum calcium observed at the time of fractures suggested their contribution to the formation of the bone lesions.

One hundred twenty seven cases of idiopathic scoliosis were evaluated by measuring. Cobb's angle, vertebral rotation. Vertebral wedging. Risser's sign and classification of the cu ve pattern using King's method.Although factors concerned with the progression of idiopathic scoliosis were not completely revealed, it was shown that at the first visit the scoliotic patients age. Risser's sign, vertebral wedging and some type of curve pattern were related to curve progression.

Intraoperative frozen section is reported to be a reliable means of identifying occult infection for preoperative evaluation of arthroplasty. The aim of this study was to determine whether the reported histopathological criteria--the existence of more than 10 polymorphonuclear cells (PMN) per high-power field--is valuable for determination of infection during the arthroplasty of patients with rheumatoid arthritis (RA). The permanent histological sections of RA synovium were analysed to study the degree of infiltration of PMNs. Furthermore, in order to examine the penetrative distribution of PMNs within the synovial tissues, immunohistochemical staining of PMNs was performed. In addition, the clinical history, from the postoperative period to the present, was investigated in 46 patients (60 joints). The presence of early- and/or late-stage postoperative infection, the development of postoperative fever, the progression of erythrocyte sedimentation rate (ESR) (more than 30 mm per hour) and the changes in CRP (more than 10 mg per litre) were further examined and compared with the histopathological tissue analyses and findings. The results demonstrated the presence of more than five PMNs per high-power field, excluding surface fibrin and inflammatory exudate in at least five separate microscopic fields in 10 joints (16.7%) of nine patients, out of 60 joints of 46 patients, in which no postoperative infection was evident. As to the magnitude of penetrative distribution of PMNs in 10 joints, there was a trend of deepening infiltration among the patients with intensive PMN infiltration. In addition, no development of postoperative fever, CRP or continuous indications of high ESR values were evident in this group. As the existence of more than 10 PMN per high-power field was not absolutely indicative of occult infection, investigation of frozen section during arthroplasty should be carefully managed.
