ABSTRACT
Objective To evaluate the effect of comprehensive schistosomiasis control measures based on infection source control in Hanchuan City marshland and lake endemic regions . Methods The data of comprehensive schistosomiasis control in Hanchuan City from 2004 to 2013 were collected and the change trends of the Oncomelania hupensis snail status and the in?fection situation of human and livestock were analyzed to evaluate the control effect. Results After the implementation of the comprehensive measures the infection rates of residents and cattle decreased from 6.38%and 8.11%in 2004 to 0.16%and 0 in 2013 respectively. There were no acute schistosomiasis patients since 2007 no new infection cases since 2011 and no infected snails since 2012. Compared with 2004 the occurrence rate of frames with living snails and the average density of living snails decreased by 56.78%and 68.35% respectively but the snail area and susceptible area increased by 0.62%and 7.10% respec?tively. In 2013 all the 367 endemic villages in 26 townships reached the criteria of transmission controlled. Conclusions The comprehensive schistosomiasis control measures based on infection source control can control the schistosomiasis transmission effectively in marshland and lake endemic regions. When consolidating the achievement the snail area in inner embankment should be compressed to prevent the schistosome re?infection in human and livestock.
ABSTRACT
Objective To evaluate the clinical effects of free fibula and flap grafts on the repair of all the first metatarsal bone at one stage.Methods There were 9 cases with the first metatarsal bone defect from Janurary 2003 to December 2009 that treated with free vascularized fibular bone and free vascularized flap at one stage.In which 6 cases reconstructed at the primary stage and 3 cases reconstructed at the second stage.Seven cases reconstructed by free vascularized fibular combined with ALTPF,two cases reconstructed by free vascularized fibular combined with TAPF.The free vascularized fibular and flap restored the first metatarsal bone and the soft tissue defects respectively.Vascular anastomosis was the artery of flap anastomosis with anterior tibial artery and the vein of the flap anastomosis with great saphenous vein,the peroneal artery and accompany vein anastomosis with artery and vein of the flap.Results The grafted tissues survived smoothly in 8 cases,vein crisis happened in I case and the ALTPF necrosis after blood vessels expedition.So the TAPF was changed to cover the soft defect and survived smoothly.Followiy-up were done from 6 to 36 months in 9 cases.There were no ulcer on flaps and no fracture again,the fibulas had been bone healing.Evaluated by Maryland standards,six cases were excellent,two cases were fine,one case was good.Conclusion The fibula combined flap grafts provide a relatively better alternative to repair the first metatarsal bone compound tissue defects at one stage.In addition,the procedure decreased frequency of operations and short the course of treatment.Sensory function reconstruction of fibula flaps should be given full attention.As fine function of the reconstructed foot,it is a effective method for reconstruction the burdened area of the foot.
ABSTRACT
@#Objective To evaluate the treatment effect of hand reconstruction with bilateral multiple toe transplantation. Methods There are four schedules as follow applied in 102 cases: (1) bilateral second toes to thumb and index finger transplantation in 86 cases; (2) wrap-around flap to thumb and second toe on opposite side to index or middle finger transplantation in 11 cases; (3) wrap-around flap to thumb and bilateral second toes to index and middle fingers transplantation in 8 cases; (4) bilateral wrap-around flap to bilateral thumb and second toe to index finger transplantation in 1 case. Results All reconstructed finger survived in 102 cases except for partial wrap-around flap necrosis in one case and second toe in two cases. Sixty-two patients got more than one-year following up. Two points discrimination in reconstructed finger was between 8 to 14 mm in all cases. The reconstructed finger grew synchronously with toe among children. Thumb opposition function recovered in all cases except for one case. Donor site: no limp or hallux eversion observed in all cases. Conclusion There is less damage on foot and most hand function recovery using bilateral multiple toe transplantation to repair hand or multiple fingers defect.
