OBJECTIVE: The prevalence of attention deficit/hyperactivity disorder (ADHD) in school-age children is 7.2%, and ADHD is divided into clinical subtypes. METHODS: The current study explored whether specific cognitive profiles as assessed using the Wechsler Intelligence Scale for Children (WISC)-IV could be obtained for each clinical ADHD subtype (ADHD-Inattentive type and ADHD-Combined type) and investigated the correlation between WISC scores and parental age at their children’s birth or birthweight. The enrolled sample comprised 12 ADHD-I and 15 ADHD-C subjects. RESULTS: An impaired Processing Speed Index was found in ADHD-I. The age of the father at the child’s birth and birthweight positively correlated with the full scale intelligence quotient (FSIQ) score in the WISC assessment. CONCLUSION: Inattentiveness within the behaviors of the children with ADHD-I is partly due to the impaired processing speed, therefore effective support for ADHD will be conducted if educator decreases their speaking speed. Since biological basis of ADHD is still largely unknown, future studies using both psychological and biological methods will reveal the etiology of ADHD. These scientific assessments will provide information for more effective approaches in the care of children with ADHD.

OBJECTIVE: Electroconvulsive therapy (ECT) is a reasonable option for intractable depression or schizophrenia, but a mechanism of action has not been established. One credible hypothesis is related to neural plasticity. Three genes (Oct4, Sox2, c-Myc) involved in the induction of induced pluripotent stem (iPS) cells are Wnt-target genes, which constitute a key gene group involved in neural plasticity through the TCF family. Klf4 is the other gene among Yamanaka's four transcription factors, and increases in its expression are induced by stimulation of the canonical Wnt pathway. METHODS: We compared the peripheral blood gene expression of the four iPS genes (Oct4, Sox2, c-Myc, and Klf4) before and after modified ECT (specifically ECT with general anesthesia) of patients with intractable depression (n=6) or schizophrenia (n=6). Using Thymatron ten times the total bilateral electrical stimulation was evoked. RESULTS: Both assessments of the symptoms demonstrated significant improvement after mECT stimulation. Expression of all four genes was confirmed to increase after initial stimulation. The gene expression levels after treatment were significantly different from the initial gene expression in all twelve cases at the following treatment stages: at the 3rd mECT for Oct4; at the 6th and 10th mECT for Sox2; and at the 3rd, 6th and 10th mECT for c-Myc. CONCLUSION: These significant differences were not present after correction for multiple testing; however, our data have the potential to explain the molecular mechanisms of mECT from a unique perspective. Further studie should be conducted to clarify the pathophysiological involvement of iPS-inducing genes in ECT.

Introduction: The diagnosis of cancer-related neuropathic pain is often difficult for non-pain medicine specialists. We examined whether a Japanese version of a neuropathic pain screening questionnaire (Japan-Q), which was developed for chronic pain, is appropriate for screening cancer-related neuropathic pain. Methods: Our palliative care team screened 104 patients from May 2014 to December 2015 and compared total points of the Japan-Q with diagnosis of the type of cancer pain by specialized pain clinicians. Validity was evaluated using a receiver operating characteristic (ROC) curve. Results: The area under the ROC curve in terms of the total score, sensitivity, and specificity for the Japan Q was 0.82, which indicated a moderate level of diagnostic accuracy. A cut-off value of 3 points was shown to be best (sensitivity: 79%, specificity: 82%). When a cut-off value of 9 points was used as the diagnostic criterion for neuropathic pain, there was greatly reduced sensitivity (sensitivity: 40%, specificity: 97%). Conclusion: Although the Japan-Q shows moderate diagnostic accuracy related to cancer pain, the cut-off value for this tool is lower than that for chronic pain. Cancer-related neuropathic pain should be suspected with a total score of 3 or more in the Japan-Q.
