    Evaluation of Articulation Disorder on Mental Disabled Children Between 3-7 Ages
    (Galenos Publ House, 2017) Unsal, Selim; Ucak, Meryem Merve; Bal, Fatih; Sarigul, Ahmet Yasin; Cengiz, Deniz Ugur
    Introduction: The aim of this thesis is to make a scientific research about the effects of mental deficiency on articulation disorders in mentally retarded children by comparing those children to the regular ones and provide the findings. Methods: The sample group of the research consists of 30 children (23 males and 7 females) with mild mental retardation whose ages range from 3 to 7 years old and 30 children (13males and 17 females) with regular mental development. The participants receive education in a special education and rehabilitation centre located. Both of the sample groups have received Ankara Articulation Test (AAT) developed by Ege, Acarlar and Turan (2004). The effects of family income, educational background of the family, gender and age factors on articulation disorders have been examined. Getting a high score from AAT test shows that is articulation disorder. Results: Mentally retarded children got higher scores than the children with normal development (p=0,000). When these two groups analysed in terms of gender, it is identified that there is a huge difference between the genders in respect to articulation sores (p<0,05). When the groups analysed according to their economic situation, mentally retarded children coming from low and lower-middle income families have less articulation problems than those who are in the high-income group (p<0,05). When the groups analysed according to educational backgrounds of the parents, there is no statistically striking difference (p>0,05), in lower education than high school while there is a noticeable difference in higher education than high school. (p<0,05). When the groups analysed according to the age factor, articulation points with no meaningful difference in the direction 3-4 years (p>0,05) but significant difference was observed between the two groups in age 5-6-7 (p<0,05). Discussion and Conclusion: Children with mild mental disabilities has articulation disorder more than the normal children.

    Hearing status in vitamin B12-deficient children
    (Wiley, 2021) Akyay, Arzu; Soylu, Erkan; Unsal, Selim; Demirol, Hatice; Bahceci, Semiha
    Aim The aim of this study is to investigate the effects of vitamin B12 deficiency on hearing in school-aged children by pure-tone audiometry. Methods Forty-three vitamin B12-deficient children and 37 age-matched control subjects were enrolled in the study. Tympanometric evaluations and pure-tone audiometry including high frequencies were performed on the subjects. The results were compared between the two groups. Results Both right and left ear pure-tone hearing thresholds (PTHTs) at 0.25-4 kHz, and four-frequency pure-tone average values were significantly better in the control group compared with the patient group (P < 0.05). However, PTHTs at 8-16 kHz were not different between the two groups (P > 0.05). Vitamin B12 level also did not show any significant correlation with the PTHTs at 0.25-16 kHz (P > 0.05). Conclusion This study indicates that vitamin B12 deficiency may contribute to hearing impairment at low frequencies as a possible aetiological factor in children.
