4 groups of subjects including 1.590 workers with occupational diseases and exposed to the risks. 175 managers, 153 health workers, 32 officals of the Labor – Invalide – Social services, social insurance in 37 factories in 7 provinces/cities: Thai Nguyen, Quang Ninh, Hanoi, Nam Dinh, Nghe An, Hue and HoChiMinh city, were enrolled into study performed from September 2001 to June 2002. The study had showed a rate of 93.8% exposed subjects underwent regular health examination of low quality. The result table delayed < 2 weeks with the cost of 35.000 VND for each subjects. In > 71.5% of fatories, occupational health examinations were conducted. The prevalence of pneumoconiosis was 94% and the cost of consultation 83.000 VND for each. There was a rather good realization of the regime of health care allowance and subsidy.

The subjects consisted of 15 processing households and 150 processing direct employees. Intervention of “Health promotion at workplaces for processing village households” according to the guide-line of WHO was implemented. The study was firstly carried out in Tien Ngoai food processing village, Khac Niem commune, Bac Ninh province from 2002-2003. The results showed that the intervention was successful. Tien Ngoai village developed its down rule, in which there were regulation on environmental protection, occupational safety. The village also established a fund for these activities. Each household carried out at least 3 improvements of working and living conditions. Commune health station in cooperation with preventive medicine centers organized medical examination and consultation for handicraft employees. Improving awareness of employees on occupational safety and environmental protection were done in different ways.

WHO and MOH collaborated to develop a pilot project on 'Health Promotion at Workplaces in SSEs and MSEs'. This project aimed to improve workers' health, helping them to protect health themselves increasing productivity and income; as a result it brings benefits to both enterprises and workers. This report presents the results that have been implemented in Hai Phong and Hue City and improvements of this model that can be applied in other places.

The dust concentration through MP 10 machine was the highest level at the city's center (M2) on February - March. The general dust concentration was the highest at the area of the cement plant (M1) in March, April, August and November of the year, was higher 3-4 times than this of Vietnamese standard. The general acute respiratory disease and respiratory disease in children were the highest at the port industrial area (M3). The results showed the respiratory disease's dependant with the time in the year and the level of dust pollution with 2 peaks on summer and the dry season.

The study was conducted on 4,800 female labourers from three regions. It was selected randomly one district from every province, 2 communes from every district and 300 labourers from every commune. The result showed that agricultural female labourers have rate of 53.5 - 55.5%, most of them are 26 - 45 years of old (73.5%). Most of them have primary and secondary education (84.7%). 11.3% of participants have high-school education and 4% have just escaped illiteracy. 88% have married and 45.9% have more than 2 live children. Working duration is long (8-17 hours per day) and most of them have not received health care periodically.

Objective To perform fetal karyotyping by percutaneous umbilical blood sampling guided by color Doppler ultrasonography in fetuses with congenital cardiac anomalies. Methods Fetal blood samples obtained by color Doppler ultrasound-guided cordocentesis in 56 fetuses with cardiac abnormalities detected by fetal echocardiography were taken for karyotyping.Fetuses were monitored post operation. Results The procedures were successfully performed in all cases and no procedure-related complications occurred.Six cases with abnormal karyotypes, 1 trisomy 21,2 trisomy 18,1 trisomy 13,1 trisomy AO and 1 cases 47XYY were identified and pre-operation ultrasonography detected multiple system anomalies besides cardiac anomalies in them. Conclusions Color Doppler ultrasonography facilitated percutaneous umbilical blood sampling by clear umbilical vein imaging and shortening the operation time.Abnormal karyotypes in fetuses with cardiac anomalies seemed to be related with multiple system anomalies.

[Objective]To find an effective method of surgical treatment of fibrous dysplasia of bone involving the femur associated with severe varus deformity.[Method]Thirteen patients with fibrous dysplasia of bone involving 14 femurs with severe varus deformity were reviewed from Feb 2002 and Jul 2005.Medial displacement of valgus or valgus osteotomies,curettage and allograft,reconstructional nail have been adolted to treat fibrous dysplasia of bone involving the femur with severe varus deformity.[Result]All patients were followed up from 8 months to 41 months with an average of 21 months.Forteen femoral mechanical alignments(axis)had been corrected completely rdiologically;the preoperative average neck-shaft angle of 75?(range,55?~100?),corrected to the average 120?(range,95 ?~135?)of postoperative,the average shortening of the femur was 3.4 cm(range,2.0~4.5 cm)preoperatively,then enlongthened by 2.8 cm(range,1.8~3.6 cm)in postoperation.Ninteen location of osteotomies showed good union in 14 femur.All bone grafts were absorbed slightly beginning at 3 months and markedly at 10 to 14 months postoperatively.Preoperation,4 patients walked with bilateral crutches,2 used unilateral cane,5 can't walk due to pathological fracture,2 without support;after operation,11 patients walk without support,2 ambulated with the aid of unilateracane.Eleven patients were painless,2 moderate pain.All had no infections and recurrent fracture and progression of the deformity.[Conclusion](1)This method can correct varus deformity,improve function,as well as restore biomechanical axis of femur.(2)It is able to effectively eradicate lesions and prevent recurrence.(3)Impaction allograft is the key of prompting allograft incorporating fully and preventing pathological fracture.
