OBJECTIVE:To evaluate zonulin and occludin levels, potentially associated with immunological pathways in the gut-brain axis, in children with attention-deficit/hyperactivity disorder (ADHD). METHOD/METHODS:We examined the association between serum levels of zonulin and occluding, and behavioral/emotional problems in children with ADHD. 40 medication-naïve children meeting Diagnostic and statistical (DSM-5) criteria for ADHD (11 females; mean (SD) age 9.4 (1.6) years) and 39 healthy comparisons (12 females; mean (SD) age 9.3 (1.9) years) were studied. Serum zonulin and occludin levels were measured by (ELISA). RESULTS:We found higher mean (SD) serum zonulin levels [37.1 (28.2) vs 8.1 (4.5) ng/mL; P<0.001) and occludin levels [2.4 (1.6) vs 0.6 (0.4) ng/mL; P<0.001] in the ADHD group compared to control group. Serum zonulin levels had a positive correlation with weight (r=0.452; P=0.003) and BMI (r=0.401; P=0.01) among children with ADHD. Serum zonulin and occludin levels also had a positive correlation with Conners parent rating scale scores (r=0.58; P<0.001), and Strengths and difficulties questionnaire scores (r=0.49; P<0.001). Multiple linear regression analysis revealed that age, sex, weight, conduct problems and oppositional sub-scores were significant predictors of increased serum zonulin levels. CONCLUSION/CONCLUSIONS:These data confirm an association between ADHD, and serum zonulin and occludin levels. Pathophysiological and clinical significance of these findings needs to be elucidated.

INTRODUCTION/UNASSIGNED:Clinical information regarding selective mutism (SM), a persistent and debilitating psychiatric disorder, in children is extremely limited. We aimed to examine sociodemographic characteristics and comorbid psychiatric conditions and identify clinical variables associated with sex and SM severity among children with SM. METHODS/UNASSIGNED:We analyzed the medical records of 49 children who received treatment for SM in four different tertiary hospitals in Turkey between 2016 and 2021. Children's charts were reviewed to examine clinical characteristics, comorbidities, and response to treatment. RESULTS/UNASSIGNED:= 0.039) than males. The vast majority of children received two or more psychiatric diagnoses. Children in the severe group had a longer duration of illness, higher rates of psychiatric comorbidity, speech delay, and treatment resistance. CONCLUSION/UNASSIGNED:Our study suggests that SM may have different clinical features according to sex and symptom severity of SM. More information about children with SM is needed to understand the development and maintenance of SM.

OBJECTIVE/UNASSIGNED:Although trichotillomania (TTM) is a common, typically pediatric-onset disorder, data on the phenomenology of TTM in children, accompanying comorbid psychiatric disorders, and treatment options are extremely limited. In our study, it was aimed to investigate these variables and related factors in patients undergoing psychiatric evaluation and follow-up. METHOD/UNASSIGNED:The study included 79 children and adolescents between the ages of 4 and 17 who were diagnosed with TTM and followed up in four different Child and Adolescent Psychiatry outpatient clinics between 2015 and 2020. The sociodemographic characteristics of these patients, clinical features of the disease, comorbid psychiatric disorders, and treatment approaches have been studied. RESULTS/UNASSIGNED:Our results showed that TTM was more common in girls, hair and eyebrow plucking was the most common, and symptoms and features accompanying TTM changed with age, but not with gender. Again, 79.7% of these children had at least one psychiatric comorbid disorder (most common being anxiety disorders and Attention Deficit/Hyperactivity Disorder), comorbidity was closely related to TTM severity, 93.7% used at least one pharmacotherapeutic agent, and positive response rates to treatment were found to be low. Moreover, TTM severity was found to increase with age and disease duration. CONCLUSION/UNASSIGNED:Study findings support that clinical presentation, disease severity and comorbidity rates may change with age in children and adolescents with TTM, and early intervention is important to prevent clinical progression/worsening and mental health sequela.

AIMS:Pandemics can cause substantial psychological distress; however, we do not know the impact of the COVID-19 related lockdown and mental health burden on the parents of school age children. We aimed to comparatively examine the COVID-19 related the stress and psychological burden of the parents with different occupational, locational, and mental health status related backgrounds. METHODS: = 3,278) of children aged 6 to 18 years, parents with different occupational (health care workers-HCW [18.2%] vs. others), geographical (İstanbul [38.2%] vs. others), and psychiatric (child with a mental disorder [37.8%]) backgrounds. RESULTS: < .001) were independently associated with significant parental distress. CONCLUSIONS:Parents report significant psychological distress associated with COVID-19 pandemic and further research is needed to investigate its wider impact including on the whole family unit.
