Two cases of bipartite tarsal navicular bone are presented. The radiographic and computed tomography (CT) findings of this anatomical variant are described. Correct recognition of this entity is important, both because it may be the cause of symptoms perse, and because it may be misdiagnosed as a fracture. When plain films are not diagnostic, CT scanning is helpful in distinguishing between a fracture and this variant. 相似文献

Computed tomography (CT) was performed in 42 patients with 49 clinically suspected tears of the posterior tibial tendon. Twenty-eight of the 49 suspected tears were subsequently surgically explored and repaired. Three patterns of tendon abnormalities were recognized on CT scans: type I-intact, hypertrophied, heterogeneous tendon; type II-attenuated tendon; and type III-absence of a portion of a tendon. Types I and II correlated with partial rupture seen during surgery, and type III correlated with complete rupture of the tendon. CT findings were accurate in 96% of the patients who underwent surgery. In four cases (14%), tendon rupture was seen on CT scans, but the extent of the injury was underestimated and the rupture was misclassified. Reactive periostitis of the distal tibia was seen in 71% of diseased tendons and may represent an important factor in the diagnosis of tendon rupture. 相似文献

The triple A or Allgrove syndrome is an autosomal-recessive disease (MIM*231550) characterized by the triad of achalasia, alacrima and adrenocorticotropic hormone (ACTH)-resistant adrenal insufficiency. Associated features of the syndrome are neurological and dermatological abnormalities. Until the discovery of the AAAS gene as the responsible gene in triple A syndrome, the diagnosis was based on characteristic clinical features. Here we present the clinical and molecular genetic data which demonstrated the marked phenotypic variability in three unrelated patients with triple A syndrome. The final diagnosis of triple A syndrome was confirmed by molecular analysis. In one patient with isolated achalasia, the diagnosis of triple A syndrome could only be made on the basis of the molecular genetic analysis of the AAAS gene. We therefore suggest that the diagnosis of triple A syndrome should be considered in patients who exhibit only one or two of the main symptoms (i.e. alacrima, achalasia or adrenal insufficiency). These patients require careful neurological investigation, and mutation analysis of the AAAS gene should be performed. 相似文献

Outcome of allogeneic stem cell transplantation for B cell chronic lymphocytic leukemia 总被引:4,自引:0,他引:4
Pavletic ZS Arrowsmith ER Bierman PJ Goodman SA Vose JM Tarantolo SR Stein RS Bociek G Greer JP Wu CD Kollath JP Weisenburger DD Kessinger A Wolff SN Armitage JO Bishop MR 《Bone marrow transplantation》2000,25(7):717-722
The objective of this study was to describe the outcome of allogeneic stem cell transplantation (alloSCT) in a series of patients with B cell chronic lymphocytic leukemia (B-CLL). Twenty-three B-CLL patients were transplanted between 1988 and 1997 using stem cells from a related (n = 20) or an unrelated donor (n = 3). The median age of the patients was 46 years, and the median number of prior chemotherapy regimens received was two. At transplantation, 14 patients had chemorefractory disease and 12 of these were refractory to fludarabine. The preparative regimens included total body irradiation (TBI) in 22 of the 23 cases. All patients received graft-versus-host disease (GVHD) prophylaxis with cyclosporine and methotrexate. Twenty patients (87%) achieved a complete remission (CR). The incidence of grade II-IV acute GVHD was 54%. Fourteen (61%) patients are alive and disease-free, including two with unrelated donors, at a median of 26 months (range, 9-115 months). Nine patients (39%) have died, one of whom had progressive B-CLL. The only favorable prognostic factor for failure-free survival (FFS) and overall survival (OS) after alloSCT was the use of a cyclophosphamide/TBI rather than an etoposide/cyclophosphamide/TBI regimen (P = 0.03). The projected 5-year FFS, OS, and relapse rates after alloSCT were 65% (95% CI, 48-88%), 62% (95% CI, 43-88%), and 5% (95%, CI 0-13%), respectively. These findings demonstrate the potential of high-dose therapy and alloSCT for inducing and maintaining a remission in patients with advanced or chemorefractory B-CLL. The low relapse rate may be due to an allogeneic graft-versus-leukemia effect. 相似文献

The substantial morbidity and mortality associated with rheumatoid arthritis (RA), while not widely appreciated, provide adequate justification for consideration of high-dose immunoablative therapy followed by hematopoietic stem cell transplantation. While some patients with RA follow a benign course, selected subsets of patients have been identified with 5-year survival rates of 40-70%. A number of factors that can be easily determined serve as useful prognostic indicators for poor outcome. These include the presence of many involved joints (total joint count), the degree of functional disability as measured by the health assessment questionnaire and the presence of rheumatoid factor. This article summarises the present status of hematopoietic stem cell transplantation for rheumatoid arthritis and proposes future directions for research. 相似文献
