RESUMO
Multiple myeloma is a plasma cell disease with the second highest incidence among hematological malignancies. Its risk of concurrent thrombosis is high, which greatly affects the quality of life and even endangers life of multiple myeloma patients. The pathogenesis of thrombosis in patients with multiple myeloma is complex, which is still unclear. However many mechanisms are considered to be related to hypercoagulable state in patients with multiple myeloma. Currently, there is a lack of thrombosis risk assessment model for multiple myeloma. Therefore, this paper reviews the research and the latest progress of venous thrombosis in patients with multiple myeloma, and provides a theoretical basis for the prevention and treatment of thrombosis.
RESUMO
Objective To evaluate the effect on treatment of multiple myeloma complicating femoral neck fracture by surgical intervention combined with drugs.Methods Twelve patients with multiple myeloma complicating femoral neck fracture were treated by cemented total hip arthroplasty femoral head shank.All of patients were received zoledronic acid treatment,at the same time,7 cases of them treated by MPT regimen (melphalan,methylprednisolone and thalidomide),3 by bortezomib combined with dexamethasone,and 1 by autologous peripheral blood stem cell transplantation.Results Twelve patients could tolerate surgery,postoperative pain was significantly reduced.Assessed by using Harris hip function score after 6 months operation,2 cases were excellent,7 cases were good,3 cases were common,excellent and good rate was 75％ (9/12).All patients were followed up for 8 months to 3 years,1 case of local recurrence after 13 months.1-year overall survival rate was 100％,2-year overall survival rate was 83％,and 3-year overall survival rate was 67％.Conclusions Multiple myeloma complicating femoral neck fracture,using bone cement in total hip arthroplasty femoral head shank to clear the local tumor lesions,receive reconstruction capability,rapid postoperative recovery,pain relief,and opportunities for further comprehensive treatments.The bisphosphonate can promote new bone formation and prevent further fractures.The surgical intervention combined with chemotherapy could relieve the symptoms,reduce tumor cell burden,improve quality of life and prolong survival time.
RESUMO
The operating principle of pulse blood oxygen saturation monitor is introduced. The usage and maintenance are discussed. Notice in using the instrument is suggested. The problem that the SPO2 detector is easy to damage is solved.
