Effect of Educational Intervention Based on Self-Efficacy Theory on the Caring Behaviour of Mothers Who Have Children With Cancer.

Self-efficacy, as one of the concepts of the empowerment model, plays a role in increasing caring behaviour. Accordingly, our study aimed to evaluate the effect of educational intervention based on self-efficacy theory on the caring behaviour of mothers who have children with cancer. This quasi-experimental study was conducted on all mothers (N = 86) of children with cancer undergoing chemotherapy who were referred to Bandar Abbas Children's Hospital. All mothers participated in 10 training sessions based on the four foundations of self-efficacy theory. The results indicated a significant increase in the mean score of mothers' self-efficacy at first and second follow-ups respectively by 10.2 and 10.9 after intervention (P < 0.001). Furthermore, the mean score of caring behaviour was increased after the intervention for the first and second follow ups by 24.6 and 25.9 from the baseline respectively (P < 0.001). The results of the present study indicated that an educational program for mothers increased their caring behaviour and self-efficacy with the increase of self-efficacy, mothers' caring behaviour was promoted. Authorities and practitioners are suggested to pay more attention to designing educational programs based on health models and theories.

Perforin gene analaysis in an Iranian family with familial hemophagocytic lymphohistiocytosis.

Perforin gene (PRF1) mutations have been reported in 20-30% of patients with familial hemophagocytic lymphohistiocytosis (FHL), an immune disorder of infancy and early childhood. Cytotoxic T and natural killer (NK) cell activities are remarkably reduced or absent in FHL patients. We report the first cases of familial hemophagocytic lymphohistiocytosis in an Iranian family with two siblings. Exons 2 and 3 of the PRF1 gene were analyzed by polymerase chain reaction (PCR) amplification and direct sequencing. Perforin gene mutation(s) were detected in none of the cases. The result of our study indicates that not much evidence is present concerning a correlation between perforin gene defects and familial hemophagocytic lymphohistiocytosis etiology in these cases.
