Self-rescue technique and Yamane’s technique in situ: Management of intraoperative haptic slippage

Haptic slippage is a frequently encountered and technically demanding complication in Yamane’s surgery. The slipped haptic could be regained when bimanual operations are workable. Management of haptic slippage is difficult when the right hand is occupied by the puncture needle, which could be solved easily with the self-rescue technique, which uses the needle tip as an intraocular instrument for better exposure and easier engagement of the slipped haptic. With the aid of bimanual operations and self-rescue technique, Yamane’s technique in situ is applicable when the haptic of dislocated intraocular lens suits for flange-making.

Disease burden of leukemia in Jiangsu Province from 1990 to 2019 / 预防医学

Objective@#To investigate the trends in the disease burden of leukemia in Jiangsu Province from 1990 to 2019, so as to provide insights into leukemia control in Jiangsu Province.@*Methods@#The prevalence, incidence, death and disability adjusted life years (DALYs) of leukemia in Jiangsu Province from 1990 to 2019 were retrieved from the 2019 Global Burden of Disease Study (GBD 2019) database, and standardized by the age structure of Chinese populations in 2000. The trends in the disease burden of leukemia in Jiangsu Province from 1990 to 2019 were analyzed using average annual percent change (AAPC). @*Results @#The average annual standardized prevalence, incidence, mortality and DALY rate of leukemia were 63.63/105, 9.76/105, 4.10/105 and 194.83/105 in Jiangsu Province from 1990 to 2019, respectively. The average annual standardized prevalence (AAPC=1.420%, t=5.644, P<0.001) and incidence (AAPC=0.806%, t=3.505, P<0.001) of leukemia appeared a tendency towards a rise, while the average annual standardized mortality (AAPC=-1.589%, t=-14.714, P<0.001) and DALY rate (AAPC=-1.849%, t=-9.046, P<0.001) of leukemia appeared a tendency towards a decline in Jiangsu Province from 1990 to 2019. Higher average annual standardized prevalence (65.27/105 vs. 62.38/105, P<0.001), incidence (10.32/105 vs. 9.29/105, P<0.001), mortality (4.69/105 vs. 3.57/105, P<0.001) and DALY rate of leukemia (216.94/105 vs. 172.80/105, P<0.001) were estimated among men than among women. The crude prevalence of leukemia peaked among patients at ages of 0 to 14 years and 60 to 74 years, and the crude incidence, DALY rate and mortality of leukemia peaked at ages of 0 to 14 years and 75 years and older.@*Conclusions@#The mortality and DALY of leukemia appeared a tendency towards a decline and the prevalence and incidence appeared a tendency towards a rise in Jiangsu Province from 1990 to 2019; however, there were high disease burdens of leukemia among men, children and the elderly.
