    Background: Myotonia congenita is the most common form of nondystrophic myotonia and is caused by Mendelian inherited mutations in the CLCN1 gene encoding the voltage-gated chloride channel of skeletal muscle. Objective: The study aimed to describe the clinical and genetic spectrum of Myotonia congenita in a large pediatric cohort. Methods: Demographic, genetic, and clinical data of the patients aged under 18 years at time of first clinical attendance from 11 centers in different geographical regions of Türkiye were retrospectively investigated. Results: Fifty-four patients (mean age:15.2 years (±5.5), 76% males, with 85% Becker, 15% Thomsen form) from 40 families were included. Consanguineous marriage rate was 67%. 70.5% of patients had a family member with Myotonia congenita. The mean age of disease onset was 5.7 (±4.9) years. Overall 23 different mutations (2/23 were novel) were detected in 52 patients, and large exon deletions were identified in two siblings. Thomsen and Becker forms were observed concomitantly in one family. Carbamazepine (46.3%), mexiletine (27.8%), phenytoin (9.3%) were preferred for treatment. Conclusions: The clinical and genetic heterogeneity, as well as the limited response to current treatment options, constitutes an ongoing challenge. In our cohort, recessive Myotonia congenita was more frequent and novel mutations will contribute to the literature.

    Early puberty paradox: an investigation of anxiety levels of mothers and children, children's quality of life, and psychiatric diagnoses
    (SpringerLink, 2023) Kardaş, Burcu; Kardaş, Ömer; Demiral, Meliha; Özbek, Mehmet Nuri
    Early puberty signs lead to an increase in anxiety levels of parents and children. The aim of this study was to investigate the quality of life and anxiety levels of girls and their mothers who were admitted to a pediatric endocrinology clinic with concerns about early puberty. Girls and their mothers who were admitted to endocrinology outpatient clinic with concerns about early puberty were compared to healthy control group. Screen for Child Anxiety Related Emotional Disorders (SCARED) parent form, Quality of Life for Children Scale (PedsQL) parent form, and Beck Anxiety Inventory (BAI) were administered to the mothers. Children were evaluated with the Schedule for Afective Disorders and Schizophrenia for School-Age Children (Kiddie-SADS Lifetime Version) (K-SADS-PL). The study sample consisted of 92 girls and 62 of them were administered to clinic with concerns about early puberty. There were 30 girls in early puberty group (group 1), 32 girls were in the normal development group (group 2), and 30 were in the healthy control group (group 3). The anxiety level of group 1 and group 2 was signifcantly higher, and their quality of life was signifcantly lower when compared to group 3 (p<0.001). Mother’s anxiety level was found signifcantly higher in group 2 (p<0.001). It has shown that anxiety level and quality of life of children were associated with anxiety level of mothers and the current Tanner stage (r=0.302, p<0.005). Conclusion: Mothers and children who have concerns about early puberty are negatively afected when early puberty is a possibility. For this reason, educating parents will prevent negative impacts of this situation on children. At the same time, it will decrease health burden.
