The role of the deficiency of vitamin B12 and folic acid on homocysteinemia in children with Turner syndrome.

OBJECTIVES: Premature atherosclerosis and ischemic heart disease represent a major cause of comorbidities among children with Turner syndrome. The identification of non-traditional risk aspects is crucial for the early identification and management of such comorbidities through establishing effective preventive measures. The aim of the study is to explore the role of the deficiency of vitamin B12, folic acid and homocysteine in children with Turner syndrome. METHODS: The study included 78 children with Turner syndrome and 67 healthy age and sex matched children. Karyotype was implemented for all patients. The serum levels of vitamin B12, folic acid and serum homocysteine were assessed. The prevalence of the deficiency of vitamin B12 and folic acid was estimated to study its correlation to hyperhomocysteinemia in Turner syndrome children. RESULTS: The karyotype analysis showed 45,X (monosomy X) in the 78 patients. Vitamin B12 and folic acid were significantly decreased in children with Turner syndrome in 65-73% of the patients, respectively, while the serum level of homocysteine significantly increased to 48.7% compared to healthy controls. Homocysteine level negatively correlated with vitamin B12 and folic acid. The deficiency of vitamin B12 and folic acid increased the risk of hyperhomocysteinemia in children with Turner syndrome (OR 2.49 and 2.36, respectively). CONCLUSIONS: This report highlights that hyperhomocyste-inemia in children with Turner syndrome may be related to the deficiency vitamin B12 and folic acid.

Sleep quality and anxiety symptoms in Egyptian children and adolescents during COVID-19 pandemic lockdown.

BACKGROUND: Coronavirus Disease Pandemic 2019 has a pervasive effect on all health aspects include psychological and mental health. This study aimed to assess the hidden stressful impact of COVID-19 pandemic on Egyptian children and adolescents' lifestyles 2 months after lockdown in Egypt by detecting symptoms of anxiety and sleep disorders. Online questionnaire was used by snowball sampling approach 2 months after lockdown targeting children and adolescents. RESULTS: The overall mean Sleep Disturbance Scale for Children score (SDSC) in participated groups was 44.6 ± 11.72. Of 765 participants 502 (65.6%) showed the symptoms suggestive of sleep disorder. Disorders of initiating and maintaining sleep were the most common among participants as 168 (33.4%) of them were suffering from it while 79 (15.7%) children were suffering from excessive somnolence. Linear stepwise regression revealed that anxiety score, understanding safety measures, and following strict quarantine measures significantly predicted SDSC (p = 0.001, 0.009, 0.046). Significant positive correlations were found between SDSC and extra screen usage, understanding safety and quarantine measures, anxiety signs, and change in child lifestyle with (p = 0.029, 0.010, 0.001 and 0.001) sequentially. Significant positive correlation was found between family income affection, SDSC, and anxiety with p value (00.001, 00.4). CONCLUSION: Child deprived of his or her normal lifestyle is vulnerable to develop anxiety symptoms and sleep disturbances. Low income, extra screen time, and restricted quarantine measures are all contributing factors that influence children and adolescent's mental health.
