ABSTRACT
AIM: We aimed to investigate sleep disturbances in children with cystic fibrosis (CF) and primary ciliary dyskinesia (PCD) and typically developing (TD) children during the COVID-19 pandemic. METHODS: Primary care givers of children with CF and PCD aged 3-16 years were asked to enrol in the study. Primary care givers of TD children were included as control group. The Sleep Disturbance Scale for Children (SDSC) was used, and questions related to sleep habits during the pandemic were asked. Results of the three groups were compared. RESULTS: Primary care givers of 33 children with CF, 16 children with PCD and 66 TD children were included in the study. There were no differences in terms of age and gender between the three groups. Changes in sleep patterns during the pandemic were more common among TD children and their families, with 75% of the children and 80% of their families sleeping later than before. The sleep initiation and maintenance disorder scores were higher in TD children (P = 0.001), whereas the sleep breathing disorder scores were higher in children with PCD (P = 0.001), and the sleep hyperhidrosis scores were higher in children with CF and PCD (P = 0.011). No relationships were found between sleep parameters and clinical findings of children with lung disease. CONCLUSIONS: Children's sleep habits have changed during the pandemic. Children with chronic lung diseases and even TD children may experience sleep disturbances during this period.

BACKGROUND: Primary ciliary dyskinesia (PCD) patients have higher incidence of sleep disordered breathing which lead neurocognitive impairments such as attention-deficit/hyperactivity disorder (ADHD). It may effect academic performance of children and may cause impairment in emotional relationships. This study aim to evaluate hyperactivity and attention deficiency in PCD patients and investigate the relationship between sleep and hyperactivity and attention deficiency in PCD patients. METHOD: Fifteen PCD patients aged 8-18 years and 31 age-matched healthy controls were compared. Ear, nose, and throat examination and home sleep testing were performed in PCD patients. Pediatric sleep questionnaire, Conners' Parents and Teacher scale and Stroop test were applied in both groups in order to investigate the relation between sleep disordered breathing and ADHD in PCD children. RESULTS: PCD patients had chronic rhinosinusitis (100%), tonsillar hypertrophy (80%) and adenoidal hypertrophy (60%). FEF25-75 was low in pulmonary function test. Sixty percent of the PCD patients had mild obstructive sleep apnea syndrome in home sleep testing. Mean AHI was 1.54 ± 0.27. Compared with the controls PCD patients had higher PSQ scores. Hyperactivity scores on Conners' Parents scale and inattention findings in Stroop test were higher in PCD patients than the healthy controls (P < 0.05). CONCLUSION: Most of PCD children had mild obstructive sleep apnea syndrome. Hyperactivity and inattention findings were higher in PCD patients. Sleep disordered breathing assessment should be a routine part of PCD patients management and these patients should be carefully monitored in terms of hyperactivity and inattention.

PURPOSE: The aim of this study was to examine interictal, pre-ictal and ictal autonomic system disturbance by comparing heart rate variability in children with uncontrolled epilepsy with that seen in healthy controls and children with controlled epilepsy. METHODS: Our study group included 20 children with refractory epilepsy, our control groups were composed of 20 children with well-controlled epilepsy and 20 healthy children. All subjects were evaluated by Holter ECG monitoring and 12-lead ECG to assess heart rate variability and QTc dispersion. The study group was also evaluated by Holter ECG during seizures. RESULTS: The study group exhibited significantly more pathological QTc dispersion than did the control groups. Heart rate variability was significantly suppressed: reduced parasympathetic activity with lower low frequency (LF) and high frequency (HF) band values were observed in the study group. Findings were similar in the well-controlled epilepsy group and the healthy group but differed from the uncontrolled epilepsy group. The examination of heart rate variability parameters during and before seizures revealed higher nLF and LF/HF ratio and lower nHF values demonstrating increased sympathetic activity. CONCLUSION: We suggest that children with refractory epilepsy have abnormalities of autonomic nervous system functioning which could be linked to the increased risk of sudden unexpected death seen in the patient group. It is possible that a chronically reduced vagal tone predisposes patients to a more dramatic stress response during their seizures. It is possible that heart rate variability parameter arising prior to seizures could be used to predict future seizures.
