ABSTRACT

Objective To analyze the epidemiological characteristics of malaria reported in the malaria surveillance system in Jinan City from 2012 to 2016,so as to provide the evidence for improving the ability of diagnosis,treatment,prevention and control of malaria.Methods The data of all reported malaria cases in the malaria surveillance system were retrospectively ana-lyzed.Results From 2012 to 2016,91 malaria cases were found in Jinan City,of which one patient died.All the cases were imported and 95.60%(87 cases)of them came from Africa(note:most of the people were Chinese residents who had been in Af-rica for the export of labor service and came back China).Falciparum malaria accounted for the most(82.42%,75 cases).All the cases were adult males,and were mainly migrant workers.The median time from onset to being confirmedly diagnosed was 5 days,and the median time from seeing a doctor to being diagnosed was 1 day.The medical institutions where the patients first visited were mainly municipal medical institutions(42 cases,46.15%).The misdiagnosis rate was 100% in village clinics and township health centers(8/8 and 2/2,respectively). The misdiagnosis rate was lowest in the municipal medical institutions (3/42,7.14%).There were 41 malaria patients(45.05%)with complications.Conclusions The situation of overseas imported malaria in Jinan City is becoming more and more serious.It is necessary to further strengthen the related professional training for doctors and strengthen the multi-sectoral cooperation for health education,etc.in order to find the cases in time and conduct the active standardized treatment,so as to prevent the second generation cases.

ABSTRACT

Objective To find out the status of prevention and control of iodine deficiency disorders and evaluate the iodine nutritional status of Jinan residents,to explore appropriate iodine level in drinking water,and to provide a scientific basis for adjustment of intervention strategies.MethodsAccording to the Monitoring Program of the National Iodine Deficiency Disorders (Trial),qualified iodized salt consumption rate,drinking water iodine content and urinary iodine levels of women of childbearing age were determined in iodine deficiency areas from 2003 to 2010.Salt iodine was detected by direct titrimetry,urinary iodine by As-Ce catalytic spectrophotometric assay and iodine in drinking water by cerous sulfate catalytic spectrophotometric method.Results Intake rate of qualified iodized salt was up to 90% and above from 2003 to 2010,median water iodine was 13.65 μg/L in the 10 counties(cities,districts),of which less than 100 μg/L accounted for 79.82%(4560/5713 ) and > 150 μg/L accounted for 12.73%(727/5713).With the increase of water iodine(0 ~ < 10,10 ~ < 50,50 ~ < 100,100 ~ < 150,150 ~ < 300 and ≥300 μg/L),urinary iodine levels of women of childbearing age increased successively(median 156.56,175.81,267.04,349.00,524.22,583.20 μg/L,respectively,x2 =121.20,P < 0.05),while the ratio of urinary iodine < 100 μg/L was significantly lower.The ratio of urinary iodine between 100 and 300 μg/L was decreased gradually,but the ratio of great than 300 μg/L was gradually increased.ConclusionsIodine deficiency areas in Jinan have reached the standard of elimination of iodine deficiency disorders.We should insist to carry out our measures to suit local conditions,classified guidances and scientific principals of iodine supplementation.

ABSTRACT

Objective To evaluate the epidemiological characteristics of brucellosis in Jinan, Shandong Province, and to analyze epidemic trend and its cause. Methods Epidemic data of human brucellosis from 2004 to 2007 in Jinan were collected from National Disease Supervision Information Management System. The rose bengal plate agglutination test(RBPT) and standard tube agglutination test(SAT) were employed to detect brucellosis in the serum samples of high-risk exposure groups involved in livestock transaction, slaughter and raising where brucellosis had been outbreak in the last three years, and epidemiological survey was conducted on the confirmed patients in 2007. Results A total of 32 brucellosis cases occurred in 2004-2007 in Jinan, among which 15 cases in 2007, 3.75 times(15/4) of those in 2004. One hundred and seventy-eight blood samples were collected from high risk population, and positive detective rate was 11.24%(20/178). Most of the patients were found in Zhangqiu and in the months from March to September, accounting for 93.33% (14/15). Farmers accounted for 93.33% (14/15) in all cases. Sixty-six point six seven percent(10/15) of the patients were over 50 years old. Male to female was 2.75: 1(11: 4) in ratio. There was a tendency of family aggregation. Two or three cases occurred in each of 3 families. All cases had a contact history with cattle and sheep, and the diagnosis were confirmed between 17-529 days(median being 70 days), in which 86.67%(13/15) of the cases were confirmed by The Centers for Disease Control and Prevention. Conclusions Brucellosis epidemic of Jinan is in an upward trend. Zhangqiu is the main epidemic region. Spring and summer are the prevailing periods, most of the patients are old male farmers were the majority of the patients. It is believed that the epidemic is primarily due to potential infection sources, incompetent quarantine of imported livestock and poor awareness of self-protection among high-risk occupational groups.
