ObjectivesTo investigate the knowledge, attitude and practice (KAP) of hepatitis E among Anlu residents and to identify the influencing factors.MethodsA stratified random sampling method was used and 1 840 Anlu residents were recruited between March 2019 and September 2019. Chi-square test and multivariate logistic regression model were used to analyze the influencing factors by SPSS 22.0 software.ResultsThe overall awareness rate of residents was 36.32%. There were statistically significant differences in age, occupation category and education (P<0.05). Qualification rate of awareness increased with age until age 40, but not with age after 40. Individuals occupationally exposed to swines (swine breeders, sales staff, slaughterers) had the lowest rates. Education level was positively associated with the qualification rate of awareness. The overall positive attitude rate was 53.89%. The overall healthy behavior rate was 82.95%.ConclusionsThe overall knowledge and awareness of hepatitis E among Anlu residents is low, especially individuals who have been occupationally exposed to swines. Health education and promotion programs are necessary.
Objective To evaluate the short-term effectiveness of Kirschner wire (K-wire) elastic fixation in the treatment of Doyle type Ⅰ and Ⅱ mallet finger. Methods Between July 2016 and March 2017, 18 patients with Doyle type Ⅰ and Ⅱ mallet finger were treated. There were 12 males and 6 males, with an average age of 45 years (range, 16-61 years). The index finger was involved in 2 cases, the middle finger in 3 cases, the ring finger in 10 cases, and the little finger in 3 cases. The interval from injury to operation ranged from 2 hours to 45 days (median, 5.5 hours). There were 8 patients of closed wound and 10 patients of open wound. Fourteen patients were simply extensor tendon rupture and 4 were extensor tendon rupture complicated with avulsion fracture. The distal interphalangeal joints (DIPJ) of injured fingers were elastically fixed with the K-wire at mild dorsal extend position. The K-wire was removed after 6 weeks, and the functional training started. Results The operation time was 34-53 minutes (mean, 38.9 minutes). Patients were followed up 3-8 months (mean, 5 months). All incisions healed primarily and no K-wire loosening or infection happened during the period of fixation. All mallet fingers were corrected. The range of motion (ROM) in terms of active flexion of injured DIPJ was (75.83±11.15)° at 6 weeks after operation, showing significant difference when compared with the normal DIPJ of contralateral finger [(85.28±6.06)°] (t=3.158, P=0.003). The ROM in terms of active flexion was (82.67±6.78)° in 15 patients who were followed up at 8 months after operation, showing no significant difference when compared with the normal DIPJ of contralateral finger [(86.00±5.73)°] (t=1.454, P=0.157). After the removal of K-wire at 6 weeks, visual analogue scale (VAS) score of active flexion and of passive flexion to maximum angle were 1.78±0.88 and 3.06±1.06, respectively. According to the total active motion criteria, the effectiveness was rated as excellent in 10 cases, good in 5 cases, moderate in 2 cases, and poor in 1 case, and the excellent and good rate was 83.33%. The patients’ satisfaction were accessed by Likert scale, which were 3-5 (mean, 4.2). Conclusion K-wire elastic fixation in the treatment of Doyle typeⅠand Ⅱ mallet finger can repair the extensor effectively, correct the mallet finger deformity, and also be benefit for the flexion-extension function restoration of DIPJ.
