RESUMO
BACKGROUND: Siblings of children with disabilities are the most likely family members to be affected by the child's disability due to the long-lasting nature of relationships between siblings compared to those of other family members. The aim of the present study was to compare the emotional-behavioral difficulties (EBD) in siblings of children with and without Sensory Impairments (SI). METHODS: The statistical population of this causal-comparative research included all siblings of children with and without SI in Shiraz, southern Iran in 2016. The sample consisted of ninety-one siblings of children with (38) and without (53) SI in Shiraz. Sample of siblings of children with SI was recruited by purposeful sampling and sample of siblings of children without sensory impairments were selected through a multistage random sampling method. Strengths and Difficulties Questionnaire (SDQ) was utilized for measuring EBD. Two way ANOVA and MANOVA tests were used for data analyses. RESULTS: Total EBD and two subscales of EBD (emotional problems and peer relationship problems) in siblings of children with SI were significantly greater than the comparison group (P<0.001). Furthermore, no significant difference was observed in the two subscales (conduct problems, and hyperactivity) between these two groups. CONCLUSION: This study provides strong evidence that siblings of children with SI are significantly at a higher risk of psychological problems, and accordingly we suggest for the related supports and services.
RESUMO
The aim of this study was to compare family communication patterns among Iranian individuals with blindness, deafness and individuals with typically developing. The statistical population consisted of all Iranian individuals with blindness, deafness and individuals with typically developing in Shiraz, Iran. The sample consisted of 116 individuals (32 individuals with blindness, 21 individuals with deafness, and 63 individuals with typically developing). The Revised Family Communication Patterns scale was used for measuring the family communication patterns. Multivariate analysis of variance test were used for data analysis. The results showed that conversation orientation in individuals with typically developing were significantly higher than individuals with blindness and deafness (P<.001). Furthermore, conversation orientation in individuals with blindness was significantly higher than individuals with deafness (P<.001). Moreover, the findings showed that the conformity orientation in individuals with blindness and deafness were significantly higher than individuals with typically developing (P<.001). It should be noted that there was no significant difference among individuals with blindness and deafness in terms of conformity orientation. The results of the study indicated that reforming of family communication patterns is essential for individuals with blindness and deafness.
RESUMO
OBJECTIVE: Oral squamous cell carcinoma (OSCC) is one of the 10 most common malignant tumors and SCC accounts for approximately 94% of all oral malignancies. The risk of malignant transformation in dysplastic lesions is greater than that of normal oral mucosa. The definite roles of mast cells and angiogenesis in OSCC have been under debate. The aim of this study was to compare mast cell count (MCC) and microvessel density (MVD) among normal oral mucosa, oral dysplastic epithelium and low- and high- grade OSCC. MATERIAL AND METHODS: A total of 42 specimens of OSCC (21 high- and 21 low-grade) were collected, along with six normal and 22 dysplastic oral mucosa. The mean MCC and MVD, as well as the correlation between them, were evaluated by immunohistochemical staining. RESULTS: Statistically significant increases in mean MCC and MVD were observed between normal oral mucosa and epithelial dysplasia, normal oral mucosa and OSCC and epithelial dysplasia and OSCC (P < 0.05), but there were no statistically significant differences in MCC and MVD between low- and high-grade OSCC. Also, the Spearman's correlation coefficient showed a significant correlation between MCC and MVD (r = 0.727, P < 0.001). CONCLUSIONS: The significant correlation found between MCC and MVD is in agreement with the idea that mast cells promote tumor progression via upregulation of angiogenesis. MCC and the degree of angiogenesis can potentially be used as indicators of the evolution of SCC from epithelial dysplasia.
