Gender and laterality in semicircular canal dehiscence syndrome.

OBJECTIVE: To determine if there is gender or laterality predilection in patients with semicircular canal dehiscence syndrome. METHODS: A multi-institutional chart review was performed to identify patients diagnosed with semicircular canal dehiscence between 2000 and 2015. A systematic literature search was conducted using PubMed to further identify patients with semicircular canal dehiscence. Age, gender and laterality data were collected. Statistical analysis was performed to evaluate for gender or laterality preponderance. RESULTS: A total of 682 patients with semicircular canal dehiscence were identified by literature and chart review. Mean age of diagnosis was 49.75 years (standard deviation = 15.33). Semicircular canal dehiscence was associated with a statistically significant female predominance (chi-square = 7.185, p = 0.007); the female-to-male ratio was 1.2 to 1. Left-sided semicircular canal dehiscence was most common, followed by right-sided then bilateral (chi-square = 23.457, p < 0.001). CONCLUSION: Semicircular canal dehiscence syndrome is most commonly left-sided and exhibits a female predominance. This may be secondary to morphological cerebral hemisphere asymmetries in both sexes and a predilection of women to seek more medical care than men.

Children's use of inanimate transitional objects in coping with hassles.

This study examined children's use of inanimate transitional objects when coping with daily hassles. Mothers of 50 preschoolers rated their children on frequency of hassles, intensity of reaction to daily hassles, coping effectiveness, and frequency of object use. No significant differences were found between those children with an inanimate transitional object and those without such an object. Among those children with an object, a significant object effect on frequency of hassles (p less than .05) and a significant object effect on coping effectiveness were found. A significant age effect was also found, indicating that older children used their inanimate transitional objects more often than younger children. Among those children with an inanimate transitional object, significant positive relationships were found between frequency of hassles, intensity of reaction to hassles, coping effectiveness, and frequency of object use. The results indicated that children who used their thumb as an inanimate transitional object experienced fewer hassles than children who used a soft object. The results also suggested that an increase in the number of hassles experienced was related to more intense reactions to hassles, less effective coping, and an increase in object use. The nature of the object and the developmental issue of separation-individuation are considered as well.
