A comparative analysis of children born with low birthweight and attention deficit hyperactivity disorder.

BACKGROUND: We aimed to compare the profile of the Wechsler Intelligence Scale for Children Fourth Edition (WISC-IV) between Japanese schoolchildren born very preterm (VP) and with very low birthweight (VLBW) and those with attention deficit hyperactivity disorder (ADHD), and to identify the specific neurocognitive characteristics of VLBW/VP children. METHODS: The VLBW/VP group in the present study included 50 (19 male, 31 female) first- to third-grade elementary school children born between January 2008 and February 2013 at Osaka Medical and Pharmaceutical University Hospital and Saiseikai Suita Hospital with birthweights <1,500 g and <32 gestational weeks. The ADHD group included 18 (13 male, 5 female) first- to third-grade elementary school children who visited Osaka Medical and Pharmaceutical University Hospital between January 2019 and October 2021. Full-scale intelligence quotient scores, four indices, and 12 subtests of the WISC-IV were calculated for all participants and compared between the VLBW/VP and ADHD groups. We assessed whether the patients' clinical history was associated with a low score on the cancellation task in the VLBW/VP group. RESULTS: The WISC-IV profiles showed similar between-group patterns, and the VLBW/VP group had lower cancellation task scores than the ADHD group. CONCLUSIONS: This is the first study to compare WISC-IV profiles between VLBW/VP children and those with ADHD. Further investigation is needed on the association between academic performance and the score of the cancellation task, and the neural mechanism of low performance for cancellation tasks in VLBW/VP children.

Impacts of long-term coronavirus disease 2019 school closures on Japanese school children.

BACKGROUND: This study investigated the impact of coronavirus disease 2019 pandemic school closures on the mental health of school students with chronic diseases. METHODS: Questionnaires were distributed to students from 4th-9th grade diagnosed with chronic diseases at Osaka Medical College Hospital and their parents or caregivers. Questionnaires from 286 families were returned by mail after the schools reopened. The students were divided into the "psychosomatic disorder" group (group P, n = 42), the "developmental disorder" group (group D, n = 89), and the "other disease" group (group O, n = 155). Using students' self-reports on the Questionnaire for Triage and Assessment with 30 items, we assessed the proportion of students with a high risk of psychosomatic disorder in three groups. We investigated how the students requiring the support of somatic symptom (SS) felt about school during school closure. Further, using parents' and caregivers' answers, SS scores were calculated before and during school closure and after school reopening. RESULTS: The proportion of students with a high risk of developing psychosomatic disorder increased in all groups. For the students in Group P, the response "I did not want to think about school" indicated an increase in SS scores, and for the students in Group O, "I wanted to get back to school soon" indicated a decrease. Furthermore, especially in Group P students, SS scores decreased transiently during school closure and increased after school reopening. CONCLUSIONS: The impact of school closure on mental health differed depending on students' diagnoses and feelings about school during school closures.

Focal seizures during adrenocorticotropic hormone therapy in a school-aged boy: a case report.

BACKGROUND: Adrenocorticotropic hormone therapy for infantile spasms, including West syndrome, has been previously reported to induce seizures. We present the findings for a school-aged child with epilepsy who developed new focal seizures during adrenocorticotropic hormone therapy. CASE PRESENTATION: The Japanese patient had posttraumatic epilepsy and developed intractable focal seizures at the age of 13 years. Adrenocorticotropic hormone therapy was administered when the patient was 14 years of age. On day 10 of treatment, he developed new focal seizures, which were characterized by left arm contractions followed by movements of touching things with his right hand and writhing and rocking his body left and right and back and forth as automatisms. The focal seizures clustered for 40 minutes and disappeared after suppository administration of 10 mg diazepam. These focal seizures did not reoccur after more than 2 years of follow-up. CONCLUSION: Adrenocorticotropic hormone-induced seizures can occur in children older than previously reported, and can occur in children with intractable seizures other than epileptic spasms.

Treatment outcomes for infantile spasms in Japanese children with Down syndrome.

BACKGROUND: The aim of this study was to assess the treatment response to conventional antiepileptic drugs and low-dose adrenocorticotropic hormone therapy for infantile spasms in children with Down syndrome. METHODS: We retrospectively investigated the response and relapse rates, electroencephalography findings, patient characteristics during drug withdrawal, and developmental outcome in 10 children with Down syndrome treated for infantile spasms in our hospital. RESULTS: All patients showed cessation of infantile spasms and achieved electroencephalographic normalization. Spasm relapse occurred in one of 10 patients (10%). Antiepileptic drugs have been withdrawn for seven of 10 patients (70%), none of whom have experienced seizure relapse since drug withdrawal. The median developmental quotient (n = 8) was 20.5, which shows that the developmental outcome was unfavorable. Low-dose adrenocorticotropic hormone therapy achieved a low seizure remission rate of 28.6%. CONCLUSIONS: Elucidation of the optimal treatment for infantile spasms in children with Down syndrome is needed to reduce the duration of infantile spasms and improve the developmental outcome.
