Alexithymia in primary ciliary dyskinesia.

OBJECTIVE: Recent evidence suggests that alexithymic deficits in emotional processing may also affect physical health, and alexithymia may also be associated with organic disorders. The emotional well-being of patients with primary ciliary dyskinesia (PCD) is often negatively affected by uncertainty about the prognosis, lack of ongoing medical care, and lack of symptom control. This study aims to evaluate the frequency of alexithymia and its possible impact on the management of childhood PCD. MATERIALS AND METHODS: Subjects were recruited from patients with PCD and healthy volunteers aged 8-18 years. The questionnaire included sociodemographic characteristics and self-report scales. Data were compared between patient and control groups. RESULTS: In the >14 years of age group, the total Toronto Alexithymia Scale (TAS-20) score was significantly higher in the patients (56.60 ± 13.01) compared to the control group (46.47 ± 7.50) (p = .007). There were 6 (30) patients with a TAS-20 score ≥61. There was a significant correlation between TAS-20 and Pediatric Quality of Life (PedsQL) score (child), but no correlation between TAS-20 and Kovacs Children Depression Inventory (CDI) and PedsQL score (parents). The TAS-20 score was significantly higher in patients with bronchiectasis (p = .035), nasal polyps (p = .045), and siblings with PCD (p = .001). Furthermore, the TAS-20 score had a significant negative correlation with pulmonary function tests. CONCLUSION: Although this study is based on limited data from a single center and cannot be generalized to all PCD patient communities, our results show that PCD patients are more likely to have alexithymia compared to healthy controls and highlight the need to evaluate for alexithymia in patients with PCD. It is important for pediatric pulmonologists to have a thorough knowledge of the alexithymic features associated with PCD and to refer patients to pediatric psychiatry when necessary, especially in patients who are noncompliant with treatment protocols.

Possible effects of N-acetylcysteine in autism spectrum disorders: major clinical aspects, eating behaviors, and sleeping habits.

BACKGROUND: N-acetylcysteine (NAC) is a promising agent for reducing irritability and hyperactivity and enhancing social responsiveness in children with autism spectrum disorders (ASD). This study aims to examine the effects of NAC on cardinal symptoms, eating, and sleeping habits in preschool children with autism. METHODS: The medical records of ASD patients were investigated retrospectively. 37 children with ASD who regularly received oral NAC in two divided doses per day (400-600 mg/day) for 8 weeks were included as the study group. The control group consisted of 21 children with ASD who were recommended NAC but never used it. The initial and second assessment scores after 8 weeks of regular use of the NAC group and control group on the Childhood Autism Rating Scale (CARS), Aberrant Behavior Checklist (ABC), Children Eating Behavior Questionnaire (CEBQ), and the Sleep Habits Questionnaire (CSHQ) were compared. RESULTS: Our findings suggested that oral NAC alleviated the intensity of cardinal autistic symptoms in areas of social withdrawal, interpersonal relationships, body use, listening response, and verbal communication. Corresponding problem behaviors such as irritability, stereotypic behavior, and hyperactivity were reduced. It was determined that there was no difference between the two groups in terms of eating behaviors and sleeping habits. CONCLUSIONS: According to the results, NAC alleviated the severity of cardinal symptoms and reduced problem behaviors in autism. Additional trials with more systematic planning, controlling for confounding effects, and long-term follow-up should be provided in future studies.

Investigation of the Relation between Epithelial Barrier Function and Autism Symptom Severity in Children with Autism Spectrum Disorder.

Autism spectrum disorder (ASD) is a common neurodevelopmental disorder characterized by limitations in mutual communication and social interaction as well as restricted, repetitive patterns of behaviors, interests, or activities. The possible role of biological abnormalities in the etiopathogenesis of this disorder arouses research interest in this area. This is a case-control study evaluating epithelial barrier function by comparing serum concentrations of occludin and zonulin in children with ASD (n = 60) and controls (n = 30). The Childhood Autism Rating Scale (CARS) was used to evaluate autism symptom levels in all children. Serum occludin and zonulin levels were analyzed using an enzyme-linked immunosorbent assay. Serum occludin was significantly lower in children with ASD than in control subjects. In children with ASD, a decrease in occludin level was significantly associated with the disorder symptom levels items mean score (CARS total scores). Our findings showed that children with ASD had alterations in epithelial barrier function compared to the control group. The investigation of the mechanism underlying the different levels of occludin between ASD and controls may be of importance in clarifying the etiopathogenesis of ASD, as well as its follow-up and treatment.

Investigation of Relaxin-3 Serum Levels in terms of Social Interaction, Communication, and Appetite as a Biomarker in Children with Autism.

OBJECTIVE: To investigate the possible relationship between relaxin-3 and autism spectrum disorder (ASD). METHODS: Serum relaxin-3 was measured in 80 children (50 children diagnosed with ASD and 30 controls). Symptom severity in the ASD group was evaluated by the Childhood Autism Rating Scale (CARS). Behavioral and nutritional problems in the groups were evaluated using the Abnormal Behavior Checklist (ABC) and the Children's Eating Behavior Questionnaire (CEBQ). RESULTS: Our findings showed that serum relaxin-3 levels were higher in children with ASD than in the controls. The listening response sub-scale score of the CARS scale was found to decrease as the level of relaxin-3 increased. However, as relaxin-3 levels increased in children with ASD, it was found that the speech problem sub-scale score on the ABC scale and the desire to drink score on the CEBQ scale increased, but the satiety responsiveness and food fussiness scores decreased. CONCLUSION: This study the first to investigate serum levels of relaxin-3, which has a role in regulating social behavior and nutritional behavior in children with ASD.

Serum B12, homocysteine, and anti-parietal cell antibody levels in children with autism.

AIMS: To compare vitamin B12, homocysteine, and anti-parietal cell antibody (APCA) levels between children with ASD and controls, paired in terms of age, sex, and socioeconomic level. METHODS: The research group consisted of 69 children, 36 with ASD and 33 controls. The severity of ASD was determined using the Childhood Autism Rating Scale (CARS). Serum vitamin B12, homocysteine and human anti-parietal cell levels were analysed using enzyme-linked immunosorbent assay. RESULTS: The serum vitamin B12 and homocysteine levels in children with ASD were lower than in the control group, but there was no significant difference in terms of APCA levels. CONCLUSIONS: Deficiencies in micronutrients, such as B12, may play a role in the pathogenesis and clinical symptoms of autism. However, it is believed that these parameters should be analysed in a wider population to clarify their effect on the aetiology of ASD.KEY POINTWe hypothesised that low levels of vitamin B12 and homocysteine levels reported in previous studies might be associated with APCA levels.The homocysteine and B12 levels were found to be significantly lower in children with ASD. There was no significant difference in serum APCA levels.No significant relationship was found between B12 levels and APCA.Given all these findings, it can be stated that vitamin B12 deficiency is not associated with an absorption-related mechanism due to the presence of APCA.Deficiencies in micronutrients, such as B12, may play a role in the pathogenesis and clinical symptoms of autism.In future studies, it will be beneficial to investigate other mechanisms that may cause vitamin B12 deficiency.

Oculogyric Crisis Due to Low-Dose Olanzapine: A Case Report.

OBJECTIVES: Oculogyric crisis is a dystonic movement disorder characterized by continuous contraction of the ocular muscles and spasmodic movements of the pupils in a fixed position, usually upward. METHODS: In this case report, an early-stage acute oculogyric crisis due to low-dose olanzapine in a 15-year-old adolescent boy is presented. RESULTS: To the best of our knowledge, this is the first report showing that acute oculogyric crisis can develop with low-dose olanzapine administration. CONCLUSIONS: Even though second-generation antipsychotics are safer than conventional antipsychotics in terms of extrapyramidal adverse effects, this possibility should always be taken into consideration through this case report.

Pediatric bone marrow transplantation: Psychopathologic features in recipients along with siblings.

OBJECTIVE: To analyze the development of psychopathology in recipients along with their donor and nondonor siblings and the relationship with the bone marrow transplantation (BMT) process. METHODS: All children were interviewed using the Kiddie Schedule for Affective Disorders and Schizophrenia to assess psychopathology. The depression and anxiety symptoms and self-esteem of children and adolescents were evaluated using the Children's Depression Inventory, State-Trait Anxiety Inventory for Children, State-Trait Anxiety Inventory, and Rosenberg Self-Esteem Scale. RESULTS: In this study, the depressive symptom level was found significantly higher in the donor group compared with the nondonor group. State anxiety symptoms were higher in the BMT group (P < .05). There were no significant differences in trait anxiety symptoms. Self-respect was higher in children in the donor group compared with those in the BMT group (P < .05). During the transplant process, children with bone marrow transplants had a higher prevalence of depression, anxiety disorder, and attention-deficit/hyperactivity disorder, and nondonor siblings had a higher prevalence of depressive disorder, anxiety disorder, and attention-deficit/hyperactivity disorder compared with society in general. CONCLUSION: Physicians should deal with the family as a whole, not just their patient, and should be aware of the psychiatric risk of other siblings during the assessment.

Hypothermia Associated With Melatonin Ingestion in a Child With Autism.

Autism spectrum disorder is a neurodevelopmental disorder characterized by social interaction and communication disorder and restrictive and repetitive behaviors. Sleep disorders are frequently observed in children with autism spectrum disorder. We present a case of hypothermia in an autistic child with a sleep disorder whose body temperature decreased to 34°C after a single dose of melatonin. Hypothermia continued for 2 more days, but her nighttime sleeping problems decreased. This case is important because it demonstrates the possible risk of hypothermia with melatonin use in children with autism with a sleep disorder.

Visual Hallucinations Induced by Clarithromycin in a Child: A Case Report and Literature Review.

OBJECTIVE: Our aim was to present a child with visual hallucinations possibly associated with oral clarithromycin administration. CASE REPORT: A 4-year-old child was admitted to our hospital with an onset of visual hallucinations after taking the second dose of clarithromycin by mouth. The symptoms gradually disappeared in a week once the clarithromycin therapy had been discontinued. She was observed for a month without any symptoms or further treatment. She was suspected of having Hoigne syndrome (also called as antibiomania) induced by clarithromycin syndrome. CONCLUSION: This report highlights neuropsychological adverse effects due to therapeutic doses of clarithromycin therapy as a possible adverse effect in children.
