BackgroundTipepidine (3-[di-2-thienylmethylene]-1-methylpiperidine) has been used solely as a nonnarcotic antitussive in Japan since 1959. The safety of tipepidine in children and adults has already been established. It is reported that tipepidine inhibits G-protein-coupled inwardly rectifying potassium (GIRK)-channel currents. The inhibition of GIRK channels by tipepidine is expected to modulate the level of monoamines in the brain. We put forward the hypothesis that tipepidine can improve attention deficit/hyperactivity disorder (ADHD) symptoms by modulating monoaminergic neurotransmission through the inhibition of GIRK channels. The purpose of this open-label trial was to confirm whether treatment with tipepidine can improve symptoms in pediatric patients with ADHD.Subjects and methodsThis was a 4-week, open-label, proof-of-efficacy pilot study for pediatric subjects with ADHD. Ten pediatric ADHD subjects (70% male; mean age, 9.9 years; combined [inattentive and hyperactive/impulsive] subtype, n=7; inattentive subtype, n=3; hyperimpulsive subtype, n=0) received tipepidine hibenzate taken orally at 30 mg/day for 4 weeks. All subjects were assessed using the ADHD Rating Scale IV (ADHD-RS), Japanese version, and the Das–Naglieri Cognitive Assessment System (DN-CAS), Japanese version.ResultsA comparison of baseline scores and 4-week end-point scores showed that all the ADHD-RS scores (total scores, hyperimpulsive subscores, and inattentive subscores) improved significantly (P<0.001). Furthermore, a comparison of baseline DN-CAS total scores and 4-week end-point scores showed a mild trend of improvement (P=0.093). Tipepidine was well tolerated, with no patients discontinuing medication because of side effects.ConclusionOur pilot study suggests that tipepidine therapy may prove to be an effective alternative treatment for pediatric patients with ADHD. Nonetheless, more detailed randomized, double-blind trials are needed to confirm tipepidine’s efficacy.

BackgroundChild abuse and/or neglect is a serious issue, and in many cases, parents are the perpetrators. Hospital-based child protection teams (CPTs) play pivotal roles in the management of not only abused and/or neglected children but also of their parents; this is generally conducted through multidisciplinary practice. The aim of this study is to survey hospital-based CPT members to determine the professions they perceive to be most applicable to participation in CPTs.Participants and methodsThe participants were members of CPTs affiliated with hospitals that had pediatric emergency departments and which were located in Chiba Prefecture; specifically, 114 CPT members from 23 hospitals responded to this survey. The two main questionnaire items concerned are as follows: 1) each respondent’s evaluation of conducting assessments, providing support, and implementing multidisciplinary collaborative practice in the treatment of abusive and negligent parents, and 2) each CPT member’s opinion on the professions that are most important for CPT activities. An exploratory factor analysis (EFA) was performed to explore the factor structure of the data, and a correlation analysis was performed using the result obtained.ResultsThe EFA returned two factors: multidisciplinary collaborative practice (α = 0.84) and assessment and support (α = 0.89). A correlational analysis showed that multidisciplinary collaborative practice had a positive correlation for obstetricians (r = 0.315, p = 0.001), neonatologists (r = 0.261, p = 0.007), midwives (r = 0.248, p = 0.011), and psychiatrists (r = 0.194, p = 0.048); however, assessment and support was only significantly correlated with midwives (r = 0.208, p = 0.039).ConclusionThis study showed that hospital-based CPT members highly evaluate multidisciplinary collaborative practice for the management of abusive and/or negligent parents, and they believe that, in addition to pediatric physicians and nurses, perinatal care and mental health professionals are the most important participants in advanced CPT activities.

Objective: The coronavirus disease 2019 pandemic has caused school closures worldwide. Japan's Prime Minister declared a state of emergency based on the coronavirus pandemic for Tokyo, Chiba, and other prefectures on April 7, 2020. Children with ADHD are particularly vulnerable to the distress caused by the pandemic and physical distancing measures, and they might display increased behavioral problems. We surveyed 15 children with ADHD, aged 11.8 ± 2.8 years old; 13 were males and 2 were females (combined subtype, n=12; inattentive subtype, n=3). The children's ADHD-RS scores were assessed by their mother (n=12), father (n=1), or nursing home staff (n=2) from before the emergency declaration (in February or March 2020) to after the emergency declaration (April or May 2020). There were no changes of treating physician, drug type or quantity, or psychotherapy or assessment person from January 2020 to May 2020. Results: A comparison of the baseline scores and secondary outcomes reveals that the ADHD-RS total score and inattentive subscore worsened significantly during this period, whereas the hyper/impulsive subscore did not. In conclusion, we suggest that policymakers, healthcare providers and families should be mindful of the potential development of inattentiveness among children with ADHD who are quarantined because of COVID-19.
