RESUMO
Objective To understand the current status of chronic filariasis patients in Huai’an City, so as to provide insights into the future care of chronic filariasis patients. Methods According to the data pertaining to the historically registered chronic filariasis patients in Huai ’an City, each case was followed up and the baseline data of chronic filariasis patients were captured using questionnaire survey. The demographic and clinical features of the patients, and the distribution and coverage of the care sites were analyzed. Results There were still 616 chronic filariasis patients in Huai’an City, including 229 men (37.2%) and 387 women (62.8%), and 93.2% were aged 60 years and older. The chronic filariasis patients were found across the 8 counties (districts) across the city, and the cases were predominantly detected in Lianshui (40.3%), Huaiyin (30.8%) and Yuyi (8.0%). There were 49.0% of the patients with lymphedema or elephantiasis alone, 10.2% with chyluria alone, 1.0% with hydrocele of tunica vaginalis alone, 2.4% with lymphatic inflammation or lymphadenitis alone, and 37.3% with two or more types of symptoms, respectively, and all cases with lymphedema or elephantiasis alone had the sites of edema in the lower limbs, with over 90% at stages I to III. Currently, there are 81 care sites in the city covering 567 patients. The mean number of care activities was 3.2 times in 2018, and the mean cumulative duration of caring activities was 18.4 years in the care sites. Conclusions Although the number of chronic filariasis patients has remarkably decreased, the number remains high in Jiangsu Province, and the cases are characterized by high age and long course of disease. Further caring activities are required to improve the quality of life in chronic filariasis patients.

RESUMO
Objective To evaluate the status of iodine deficiency disorders(IDD) in Huai'an City in 2011 and to provide a scientific basis for adopting target prevention strategies timely and adjusting the intervention policy scientifically.Methods According to The National Project of Surveillance on IDD,probability sampling method (PPS) was used to select 30 counties in Huai'an City,and one primary school was selected randomly from each county,then 40 children aged 8 to 10 were randomly selected in each school.Children's thyroids were examined by palpation and the iodine in salt samples collected in their home was tested by direct titration.At the same time,urine samples from 12 children of the 40 selected children were collected and urinary iodine was tested by As(Ⅲ)-Ce4+ catalytic spectrophotometry.Questionnaire survey of IDD was conducted among 30 students of grade 5 and 5 housewives around that school.Results A total of 1200 children aged 8 to 10 were examined,and the goiter rate was 1.3％(15/1200).All the goiters were level Ⅰ.The goiters of each age group was 0.8％(3/390),1.8％(7/390) and 1.3％(5/420),respectively.The 360 urine samples were collected from children aged 8-10,and the median of urinary iodine was 171.5 μg/L with the proportions of ＜ 20 μg/L,＜ 50 μg/L and ＜ 100 μg/L were 0(0/360),1.1％ (4/360) and 5.6％ (20/360),respectively.A total of 1200 salt samples were tested in children's family.The coverage rate of iodized salt was 99.4％ (1193/1200) and the qualified rate of iodized salt was 97.7％ (1165/1193).The consuming rate of qualified iodized salt was 97.1％(1165/1200),and non iodized salt rate was 0.6％(7/1200).The knowledge rates of IDD were 82.7％ (2234/2700) and 69.8％ (314/450) in 900 students and 150 housewives,respectively.Conclusions In Huai'an City,except the knowledge rate of IDD,the goiter rate and urinary iodine of children aged 8-10,iodized salt consumption maintain at the stage of the target level.In addition to strengthen the monitoring of iodized salt and to supply qualified iodized salt,it should also increase the focus on health education propaganda in the future.
RESUMO
Objective To explore the distribution of water with high level arsenic and prevalence of arsenism along Huai'he River and the surrounding area of Hong'ze lake in Huai'an of Jiangsu. Methods Wate rsamples were collected and tested in 2008 from 18 villages of 6 towns according to history data in 3 counties like Xuyi,Jinhu and Hongze. Samples having arsenic level higher than 0.05 mg/L were investigated by epidemiological method and the patients were diagnosed by Standard of Diagnosis for Endemic Arsenism. Results All 5199 water samples were determined,and 260 water samples were exceeding the national drinking water quality level (0.05 mg/L) in 3 counties,the rates of exceeding diagnosis were 5.6%(247/4454),0.7%(4/597),6.0%(9/148) respectively. Total detected rate of endemic arsenic disease was 5.94%(128/2155). The detected rates of age group of 0 ～ ,20 ～,30 ～ ,40 ～ ,50 ～ ,60 ～ ,70 ～ ,80 ～ were 2.86%(1/35),2.11%(2/95),1.26%(3/239),3.10%(16/516),5.53% (32/579),10.07%(41/407),11.84%(27/228),10.71%(6/56) respectively. The detected rate of male (9.10%,78/857) was higher than that of female(3.85%,50/1298,χ~2 = 25.46,P < 0.01). Conclusions Huai'he River and the surrounding areas of Hong'ze lake like Xuyi,Jinhu and Hongze are identified existing endemic arsenic disease area. The prevention of arsenism should be strengthened in these areas.
