Analysis of genetic and non genetic risk factors for cisplatin ototoxicity in pediatric patients.

OBJECTIVE: The aim of this study was to analyse the genetic and non genetic risk factors for cisplatin ototoxicity. METHODS: This study was conducted on 72 children who received cisplatin based chemotherapy. Brock and Muenster classifications were used to evaluate ototoxicity seen in these children. 6 single nucleotide polymorphisms (SNP); ERCC1 rs 11615, GSTP1 rs1138272, GSTP1 rs1695, LRP2 rs 2075252, TPMT rs 12201199, COMT rs 9332377, were evaluated as genetic factors by real time PCR. Non genetic factors such as cranial irradiation, cumulative doses of cisplatin, age, gender, administration of other ototoxic drugs were analysed as well. By using Chi-square test, risk factors were matched with the ototoxicity classifications. Significant risk factors were reevaluated using logistic regression modelling. RESULTS: According to univariate analyses, male gender, co-treatment with aminoglycosides and mutant genotype of GSTP1 rs1695 were significantly related with cisplatin ototoxicity. Logistic regression modelling analyses also showed that male gender, co-treatment with aminoglycosides were found to be significantly related with cisplatin ototoxicity. Mutant genotype of GSTP1 rs1695 was not found to be significant, but close to the level of statistical significance. CONCLUSION: Male gender, co-treatment with aminoglycosides are significant risk factors for cisplatin ototoxicity in pediatric patients. Mutant genotype of GSTP1 rs1695 seems to be a genetic risk factor in univariate analyses, although not confirmed by multivariate analyses. Therefore, GSTP1 rs1695 SNP needs to be studied in larger series.

The effect of dance over depression.

Dance and movement therapy are consisted of music, easy exercises and sensorial stimulus and provide drugless treatment for the depression on low rates. In this study, it has been aimed to examine the effect of dance over the depression. A total of 120 healthy male and female conservatory students ranged from 20 and 24 ages volunteered to participate in this study. They were divided randomly into 1 of 2 groups: dance training group (DTG; N = 60) and control group (CG; N = 60). A dance training program was applied to the subjects three days a week (Tuesday, Thursday, and Saturday) during 12 weeks. The subjects in the control group did not participate in the training and participated only in the pre and post test measurements. Beck Depression Scale was used for the pre and post test measurements of subjects. 12 weeks of dance training has been found to be effective on the depression levels of the subjects participating in the research as the training group (p < 0.05). The depression level of males and females before training has meaningfully decreased after 12 weeks of dance training (p < 0.05). When the depression levels of the subjects participated in research as the control group were separately evaluated for males and females, no meaningful change has been found in the depression levels during 12 weeks (p > 0.05). In conclusion, it has been seen that dance affects the depression levels of university students positively and decreases their depression levels.
