ABSTRACT

OBJECTIVE: To understand the distribution characteristics of new silicosis cases in Inner Mongolia from 2006 to 2018.METHODS: Through the Pneumoconiosis Report Card of Occupational Disease and Occupational Health Monitoring Information System, a subsystem of China Disease Prevention and Control Information System, the data of new cases of silicosis reported in Inner Mongolia from 2006 to 2018 were collected and analyzed by routine data analytic method. RESULTS: A total of 903 new cases of silicosis were reported in this area from 2006 to 2018. Most of the cases are in males that account for 98.8%(892/903). Among them, there were 536 cases of silicosis stage Ⅰ, 259 cases of silicosis stage Ⅱand 108 cases of silicosis stage Ⅲ. The median age of onset was 48 years old and the median length of service for dust exposure was 11.4 years. The industrial distribution was concentrated in nonferrous metal mining and dressing, coal mining and washing, accounting for 66.2% and 9.3% respectively. Private enterprise was the main economic type, accounting for 64.3%. The enterprises were dominated by small-and medium-sized enterprises, accounting for 35.6% and 32.0% respectively. The main types of work were rock driller and hauler, accounting for 39.4% and 17.1% respectively. The geographical distribution was dominated by Chifeng City, Bayannaoer City and Baotou City, accounting for 53.7%, 14.1% and 13.5% respectively. CONCLUSION: In order to better protect the occupational health of workers, it is necessary to strengthen the dust exposure control and protection of non-ferrous metal mining, coal mining and washing industries, private enterprises, and small-and medium-sized enterprises, rock drills and transport workers in Chifeng, Bayannaoer and Baotou Cities.

ABSTRACT

Objective To understand the basic information and epidemic characteristics of new cases of cysticercosis in Dali Prefecture, Yunnan Province, so as to provide the evidence for formulating the prevention and control strategy of cysticercosis. Methods The data of inpatients in the Dali Parasitic Disease Prevention and Control Center from 2014 to 2017 were collected and the eligible data of new cases of cysticercosis were analyzed by the epidemiological method. Results There were 1 552 patients with cysticercosis, including 549 new cases of cysticercosis. Among the new cysticercosis patients, most were neurocysticer-cosis cases (484 / 549, 88.16%). The symptoms included epilepsy and headache (51.73%), headache (40.98%), and dizziness (18.76%). The new cysticercosis patients were mainly middle-aged male farmers of Bai nationality, and they were distributed in all counties (cities) of Dali Prefecture, especially in Eryuan County (26.78%), and Dali City (19.49%). The annual incidence rate was 4.423/105 in 2014, 3.837/105 in 2015, 3.765/105 in 2016, and 3.442/105 in 2017, and there was no significance among the different years’incidence ( χ2 = 4.595, P > 0.05). Conclusion Dali Prefecture is still an endemic area of cysticercosis. Therefore, the monitoring, prevention and control of the disease should be strengthened.

ABSTRACT

Background: Aim of current study was to determine the clinical characteristics, radiological, laboratory features and anti-tubercular drug sensitivity in new smear positive (category I) pulmonary tuberculosis cases in a tertiary care dedicated TB OPD, Delhi. Methods: The study was a cross-sectional observational study and consists of 100 cases of new smear positive pulmonary tuberculosis cases (category I) irrespective of age and sex. The sputum were collected, stained with Ziehl-Nielsen (Z-N) staining and ultimately inoculated on Lowenstein-Jensen (L-J) media for six weeks. All sputum smear positive cases were subjected to culture and drug-susceptibility testing by 1% proportion method on Lowenstein-Jensen (LJ) medium. The Drug-Susceptibility Testing (DST) for isoniazid (INH), rifampicin (R-cin), ethambutol (EMB) and streptomycin (SM) were performed. Results: The age & sex distribution of 100 patients showed that majority of the patients (79%) belonged to 2nd, 3rd and 4th decades & 60 % were males and 40% were female with male to female ratio 3:2 respectively. Cough (83%), fever (77%) and weight loss (76%) were the most common presenting clinical features. The chest X-ray of 100 smear positive patients showed that 53% of patients had evidence of 35% unilateral and 18% bilateral consolidation and 46% had cavitary lesions on chest X-ray (PA view) with 37% and 9% of patients having unilateral and bilateral cavities respectively. Of these 82 culture positives, 56.1% (n=46) were susceptible to all first-line anti-tubercular drugs, while 43.9% (n=36) were resistant to mostly one or other anti-tubercular drugs (INH, R-cin, SM or EMB). Conclusion: We stressed the importance of early diagnosis of new cases by clinico-pathological features, identifying of drug resistance trends in anti-tubercular treatment naïve patients, in order to assess the efficacy of current interventions. Overall, these findings emphasize the importance of early diagnosis of drug resistance pattern of M. tuberculosis isolates to anti-tubercular in category I patients as well as its association with HIV across the country to timely modify and strengthen the national programs in order to prevent the emergence of MDR-TB strains and avert the threat of XDR-TB.

ABSTRACT

Medical insurance, which is mandatory in Korea, has been progressed in the way of expanding the relevant population and intensifying the guarantee. However, rapid increases in medical expenses led national health insurance into a state of financial crisis. The government considered the reason of financial crisis as fee-for-service and started reorganizing the terms of payment from fee-for-service to case-payment. Therefore, an expanded diagnosis related group (DRG) payment system is carried out to decrease the expense on health and to secure financial stability. At the same time, the new case-payment system, apposite to the medical case in Korean society, is under demonstration. DRG payment system is in execution for the 7 disease entities of the four departments requested for now. However, it is supposed to be carried out in all the hospitals from the second half of 2012 and be expanded to all the general hospitals from 2013. The new case-payment system is under development because it is difficult to apply DRG to all disease entities. These shake-ups in the payment system will be conducted from the year 2015, combining both the DRG and new case-payment system. Basically, the introduction of the new case-payment system will cause doctors' passive attitude in the treatment of patients. This would be an especially serious problem for the department of surgery whose charge for operation is very low. It would be worse for the vascular surgeons because only 80% of operational or interventional procedures will be compensated, the fee for ultrasound is included in the new case-payment system, and age-related severity is not reflected in the disease entity. If relaunch is inevitable, vascular surgeons should understand the new case-payment system exactly and point out the problems. Also, standard guidelines on treatment per procedure should be set up and used for the established case-payment system, which would be helpful in reducing unnecessary medical expenses.

ABSTRACT

Background & objectives: The prevalence of multidrug-resistant tuberculosis (MDR-TB) is increasing throughout the world. Although previous treatment for TB is the most important risk factor for development of MDR-TB, treatment-naïve patients are also at risk due to either spontaneous mutations or transmission of drug-resistant strains. We sought to ascertain the prevalence of MDR-TB among new cases of sputum-positive pulmonary TB. Methods: This was a prospective, observational study involving newly diagnosed cases of sputum-positive pulmonary tuberculosis diagnosed between 2008 and 2009 carried out in New Delhi, India. All sputum-positive TB cases were subjected to mycobacterial culture and first-line drug-susceptibility testing (DST). MDR-TB was defined as TB caused by bacilli showing resistance to at least isoniazid and rifampicin. Results: A total of 218 cases of sputum-positive pulmonary tuberculosis were enrolled between 2008 and 2009. Of these, 41 cases had negative mycobacterial cultures and DST was carried out in 177 cases. The mean age of the patients was 27.8 ± 10.2 yr; 59 patients (27%) were female. All patients tested negative for HIV infection. Out of 177 cases, two cases of MDR-TB were detected. Thus, the prevalence of MDR-TB among newly diagnosed pulmonary tuberculosis patients was 1.1 per cent. Interpretation & conclusions: MDR-TB prevalence is low among new cases of sputum-positive pulmonary TB treated at primary care level in Delhi. Nation-wide and State-wide representative data on prevalence of MDR-TB are lacking. Efforts should be directed towards continued surveillance for MDR-TB among newly diagnosed TB cases.

ABSTRACT

The relationship of cause-result between low selenium (Se) and Kashin-Beck disease (KBD) was probed by the prospective study of epidemiological method with regarding low-Se as an exposure factor in this paper. 597 healthy children lived in KBD areas with low, middle and high prevalence were divided into the low-Se exposed group and the non-low-Se exposed group according to their Se content in hair. The low-Se exposed group was divided into three subgroups, such as Se content in hair≤110 ng/g, 110 ng/g<Se content in hair≤150 ng/g and 150 ng/g<Se content in hair≤200 ng/g, respectively. Six new cases of the total with KBD (incidence was 0.574% person-year) were found in the low-Se exposed group during three years period of the investigation. No new case was found in the non low-Se exposed group . KBD incidence was not significantly different between those two groups. Two new cases were found in children with Se content in hair kept below 110 ng/g during three years (incidence: 1.21% person-year). SMR in each group indicated that the new cases observed in the low-Se exposed group was remarkable lower than the new cases expected. It was not observed that the dose-response relationship between low-Se and KBD, and was not supported that the low-Se was a predominant factor to cause KBD.
