Objective To investigate rheumatic disease manifestations in patients with myelodysplastic syndromes and explore possible causes.Methods Nine myelodysplastic syndromes(MDS)inpatients with rheumatic disease manifestations were reviewed retrospectively.Results Nine patients with the diagnosis of MDS had active rheumatic disease manifestations with various degree of hypergammaglobulinemia and positive autoantibodies.Two patients had rheumatoid arthritis(RA)and RA+anti-phospholipid syndrome(APS),four systemic lupus erythematosus(SLE)and SLE+polymyositis(PM),one patients had adult onset Still's disease, one with acute arthritis and cutaneous vassulitis,one had lupus-like manifestations including polyserositis,al- buminuria,hypocomplementemia and positive Commb's test.Conclusion The rheumatic disease manifesta- tions in patients with myelodysplastic syndromes are characterized by various active rheumatic disease manifes- tation.Immunological abnormalities and ineffective hematopoiesis are persistent.Immunologic abnormalities in MDS such as impaired function of T and B cells,hypergammaglobulinemia,positive autoantibodies,may be the causes of various rheumatic manifestations.We suggest that there is a significant association between myeludys- plastic syndrome and rheumatic diseases.

Objective To discuss the donor site complications and the treatments of the anterolateral thiIgh flap transfer. Methods From July 1988 to July 2007,427 patients treated by anterolateral thish flap surgery were followed up.The donor sites were treated by several methods,including direct closure(49 cases),skin graft transfer(258 cases),anterolateral fascial flap transfer(27 cases),musculocutaneous flap and skin sraft transfer(65 cases), superficial epigastric artery flap transfer(28cases).The area of these flaps ranged from 30 cm×10 cm to 18 cm×7 cm.and the average follow-up was 21 months(ranged from 8 months to 54 months). All the data was analyzed by SPSS for Windows,Version 11.0.1. Results Short-term complications(within 4 weeks)and long-term complications (over 6months)were observed.The former included skin necrosis(5.4%),wound infection(4.0%),and necrosis of rectus femoris(0.5%); and the latter included chronic ulcer(4.9%), aerious scar(6.6%), serious discomfortable(5.9%),and quadriceps femoris disfunction(3.7%).The statistical results showed that there was a close correlation between the donor site morbidity and the surgical methods. Conclusion The complications of the donor site cannot be ignored.Protect the soft-tissue of the donor site carefully,design all appropriate operation plan.Careful preoperative examination and local flap transplantation can effectively decrease the rate of complications.

Objective To study the anatomy of superficial palmar digital veins in fingertip,and explore the clinical application of superficial palmar digital veins as venous drainage in fingertip replantation.Methods One hundred fingers were studied with three methods: microanatomy,sectional anatomy,and X-ray.According to microanatomical observation,thirteen fingers in 10 cases with fingertip amputations and dorsal veins defect were replanted by anastomosis of palmar digital veins to reconstruct the venous drainage of the amputated digits. Results ( 1 ) 1 to 3 tiny superficial palmar digital veins can be found at the level of the onychorrhiza.The average diameters of the superficial palmar digital veins were 0.2-0.5 mm.(2)In clinical practice,13 replanted fingers were survived.After 3-18 months following-up,the appearance and function were satisfactory. Conclusion The distribution of the palmar digital veins was in some pattern.Anastomosis of the superficial palmar digital veins can not only improve the success rate of the fingertip replantation,but also avoid the complications of the other venous drainage methods.

Objective To evaluate the clinical effect of the reversed saphenous fasciocutaneous island flap combined with the VSD therapy in plate exposure of the distal tibia.Methods From January 2008 to July 2010,seven patients with hardware exposure following internal fixation of the distal tibia fracture were treated by VSD therapy and reversed saphenous fasciocutaneous island flap reconstruction.The VSD therapy was performed from 7 to 26 days after hardware exposure,and the flap transfer was performed 7 to 14 days after the VSD therapy.The size of the soft-tissue defect ranged from 4 cm × 2 cm to 13 cm × 4 cm.The mean follow-up was 10.6 months after the fracture (range,8-14 months).Results The average times of the VSD therapy was 1.3.After VSD was removed,the exposed hardware was covered by healthy granulation tissue in all cases.All flaps were successfully transplanted,and the size of flap ranged from 6 cm × 3 cm to 15 cm × 6 cm.Six of 7 flaps survived completely without further procedures.The necrosis of the distal margin of the flap occurred in 1 patient.A solid bony union was confirmed by the X-ray in all patients after 4-6 months postoperatively.No skin defects or fistulae were observed.Conclusion The combination of the reversed saphenous fasciocutaneous island flap and VSD therapy could save the exposed hardware and cover the soft tissue defects in the distal tibia.
