ABSTRACT
OBJECTIVE: To analyze the characteristics of newly diagnosed pneumoconiosis in gem processing industries in Guangdong Province from 2006 to 2016.METHODS: Data from Direct Reporting System for Occupational Disease Network in the gem processing industries in Guangdong Province from 2006 to 2016 were collected and analyzed according to pneumoconiosis disease category, regions, industry and enterprise characteristics.RESULTS: There were 202 new diagnosed pneumoconiosis cases in gem processing industry in Guangdong Province from 2006 to 2016,which showed a general decline trend after peaking in 2008.Among 202 cases,192 cases( 95.0%) were silicosis,9 cases( 4.5%) were other pneumoconiosis,1 case( 0.5%) was welder pneumoconiosis; 143 cases( 70.8%) were stage Ⅰ pneumoconiosis,44 cases( 21.8%) were stage Ⅱ pneumoconiosis,15 cases( 7.4%) were stage Ⅲ pneumoconiosis; 196 cases( 97.0%)were male and 6 cases( 3.0%) were female.The mean age for diagnosis was( 36.3 ± 0.4) years,and the median dust exposure duration was 9.6 years.There was 86.1% of cases centered at the Pearl River Delta region and 94.6% of cases working in jewelry and related goods manufacture industry,which were more commonly from Hong Kong,Macao,Taiwan and private own economy enterprises( 94.1%),as well as large and small enterprises( 72.2%).There was 38.2%( 21/55) of the enterprises reporting 2 or more cases,of which 3 enterprises had more than 10 new cases.The job titles of these cases were mainly drilling,cutting,sculpturing and stone cutting.CONCLUSION: The prevalence of pneumoconiosis in gem processing industries in Guangdong showed a decreasing tendency, but there is a potential risk of group onset of pneumoconiosis.The prevention and control procedures for dust hazard should be strengthened in gem processing industries.
ABSTRACT
Objective To investigate the postoperative complication and nursing experience of hand-assisted laparoscopic J-type ileal pouch-anal anastomosis (IPAA) in familial adenomatous polyposis (FAP). Methods A total of 36 patients with FAP who had undergone hand-assisted laparoscopic J-type ileal pouch- anal anastomosis (IPAA) were analyzed retrospectively. Results The postoperative complication included ileal pouch bleeding in 2 cases, urinary retention in 3 female patients, external hemorrhoids swelling in 3 cases, and anastomotic fistula in 2 cases. Six cases had ileum pouch inflammation during the postoperative follow- up. All the complications were relieved after conservative medical therapy. Conclusions IPAA operation puts forward high technical requirements with more postoperative complications. Therefore, it is important to strengthen nursing of the patients, reduce postoperative complication and increase quality of life of FAP.
