Ureteral cancer associated with dermatomyositis

Dermatomyositis is a rare inflammatory myopathy that has characteristic cutaneous lesions. Although many malignancies are associated with dermatomyositis, urogenital malignancies have rarely been reported to be associated with dermatomyositis. We report here on the first case of ureteral cancer associated with dermatomyositis. A 42-year-old man presented to us with a skin rash. A clinical diagnosis of dermatomyositis was made due to the skin lesions, muscle weakness, arthralgia, the increased erythrocyte sedimentation rate and the increased creatine kinase level. The patient revealed microscopic hematuria and abnormal urine cytology during the investigation for the underlying malignancy. Retrograde pyelography demonstrated a suspicious lesion in the right mid-ureter, and the ureteroscopic biopsy revealed the urothelial carcinoma. Although an operation was recommended, the patient died of pneumonia associated with his interstitial lung disease, which is one of the poor prognostic indicators of dermatomyositis.     

Floating thumb with double dislocation of carpometacarpal and metacarpo-phalangeal joints

INTRODUCTION

Double dislocations of carpometacarpal and metacarpo-phanlageal joints are rare. We report an unusual case of simultaneous dislocation of both CMC and MCP joints in the thumb.

PRESENTATION OF CASE

A 31 year old male was admitted following a road traffic accident. He was complaining of pain and deformity of right thumb. The X-ray examination revealed simultaneous dislocation of both CMC and MCP joints. He underwent closed manipulative reduction and percutaneous K wire fixation. The wires were removed after six weeks. After a course of physiotherapy he regained full range of pain free movements.

DISCUSSION

The incidence of simultaneous dislocation of both CMC and MCP joints in thumb are associated with high energy injuries. The options of treatment are conservative with cast immobilisation and serial X-rays or operative including closed manipulative reduction and K wire fixation or open reduction and internal fixation.

CONCLUSION

The option of treating this rare injury with closed manipulative reduction and percutaneous K wiring gives excellent and predictable results.     

Long‐term outcome of belatacept therapy in de novo kidney transplant recipients – a case‐match analysis

While belatacept has shown favorable short‐ and midterm results in kidney transplant recipients, only projections exist regarding its potential impact on long‐term outcome. Therefore, we performed a retrospective case‐match analysis of the 14 belatacept patients originally enrolled in the phase II multicenter trial at our center. Fifty six cyclosporine (CyA)‐treated patients were matched according to age at transplantation, first/retransplant, and donor type. Ten years after kidney transplantation, kidney function remained superior in belatacept‐treated patients compared with the CyA control group. Moreover, none of the belatacept‐treated patients had donor‐specific antibodies ≥10 years post‐transplantation compared with 38.5% of tested CyA‐treated subject (0/10 vs. 5/13; P = 0.045). Notably, however, patient and graft survival was virtually identical in both groups (71.4% vs. 71.3%; P = 0.976). In the present single‐center study population, patients treated with belatacept demonstrated a patient and graft survival at 10 years post‐transplant which was comparable to that of similarly selected CNI‐treated patients. Larger studies with sufficient statistical power are necessary to definitively determine long‐term graft survival with belatacept.
