The aim was to comprehensively examine school-based tobacco policy status, implementation and students’ perceived smoking at school in regard to gender-specific differences in smoking behavior. We conducted a multilevel-based study to assess two-level effects for smoking among 2350 grades three to six students in 26 randomly selected elementary schools in southern Taiwan. A series of multilevel models were analyzed separately for male and female students. The school-level variables appear to be related to smoking behavior in male students. Among males, the risk of ever-smoking was significantly associated with those schools without antitobacco health education activities or curricula [adjusted odds ratio (aOR) = 6.23, 95% confidence interval (CI): 2.55–15.24], with a high perceived smoking rate (aOR = 3.08, 95% CI: 1.41–6.72) and located in a mountainous region (aOR = 2.53, 95% CI: 1.15–5.58). The risk of ever-smoking among females was significantly associated with those schools without antitobacco activities or curricula (aOR = 3.10, 95% CI: 1.27–7.55). As compared with female counterparts, the specific school that the male students attended had a positive significant effect on the risk of being ever-smokers. The findings suggest that effective tobacco policy implementation should be considered in elementary schools that are currently putting children at the greatest risk for cigarette smoking, especially in regard to male students.

  Background

Severe glenoid bone loss in recurrent anterior glenohumeral instability is rare and difficult to treat.

Purpose

The authors present a surgical technique using allogeneic bone grafting for open anatomic glenoid reconstruction in addition to the capsular shift procedure.

Study Design

Case series; Level of evidence, 4.

Methods

Nine consecutive patients with a history of recurrent anterior shoulder instability underwent reconstruction of large bony glenoid erosion with a femoral head allograft combined with an anteroinferior capsular shift procedure. Preoperative computed tomographic and arthroscopic evaluation was performed to confirm a ≥120° osseous defect of the anteroinferior quadrant of the glenoid cavity, which had an "inverted-pear" appearance. Patients were followed for at least 4.5 years (range, 4.5–14). Serial postoperative radiographs were evaluated. Functional outcomes were assessed using Rowe scores.

Results

All grafts showed bony union within 6 months after surgery. The mean Rowe score improved to 84 from a preoperative score of 24. The mean loss of external rotation was 7° compared with the normal shoulder. One subluxation and 1 dislocation occurred after grand mal seizures during follow-up. These 2 patients regained shoulder stability after closed reduction. The remaining patients did not report recurrent instability. All patients resumed daily activities without restricted motion.

Conclusion

This technique for open reconstruction is viable for the treatment of recurrent anterior glenohumeral instability with large bony glenoid erosion.
