RESUMEN

Background: Yokukansan is a traditional Japanese herbal medicine that is widely administered to individuals of various age groups as an effective drug for anxiety, with few side-effects. While animal studies have yielded promising results concerning yokukansan's potential in treating anxiety disorders, comprehensive validation has remained incomplete. Moreover, most of the clinical investigations regarding yokukansan have primarily focused on Japanese subjects, and its impact on non-Asian ethnicities remains unverified. Case Presentation: We present the case of a 17-year-old Caucasian female with panic disorder (PD). Following her relocation to Japan, she experienced panic attacks due to environmental changes, which subsequently prompted her to visit to our clinic. Various medical examinations revealed no abnormalities, which ruled out the possibility of any physical illness other than PD. Significantly, the administration of yokukansan resulted in a notable reduction in panic attacks, as well as in anticipatory anxiety, accompanied by discernible enhancements in psychosocial functioning and overall quality of life. Furthermore, it is imperative to underscore the fact that no noteworthy adverse events took place. Conclusion: Panic attacks and profound anxiety in a Caucasian patient with PD were successfully treated with the use of yokukansan. This case study suggests that yokukansan may be effective in treating PD in Caucasians as well as in Asians. However, to substantiate this preliminary observation, further investigations are required.

RESUMEN

Bulimia nervosa (BN) and other specific feeding or eating disorders with subthreshold BN symptoms (OSFED-BN) are characterized by recurrent binge eating episodes accompanied by compensatory behaviors, including excessive exercise. We aimed to examine the role of compensatory exercise on several clinical disorder-related variables and the treatment outcomes. The sample included 478 patients diagnosed with either BN or OSFED-BN admitted for a 16-week eating disorder-specific treatment program. A battery of questionnaires was administered to evaluate eating and general psychopathology, and personality traits. Other clinical disorder-related data, including levels of compensatory exercise, were assessed through a semi-structured clinical interview. Between-group comparisons of compensatory exercise levels were analyzed, as a predictive model of risk of poor treatment outcomes. Path analysis was conducted using structural equation models to estimate the direct and indirect effects between the main variables. Higher levels of self-reported compensatory exercise were associated with greater eating psychopathology, general psychopathology, and more dysfunctional personality traits and were a predictor of poor treatment outcomes. Additionally, these levels achieved a mediating role in several paths contributing to a higher likelihood of a poor outcome. Further research is required to determine how psychotherapeutic approaches can be optimized to adequately include adaptive exercise for these patients.

RESUMEN

BACKGROUND: The purpose of this study was to develop an internet-based Guided Self-Help CBT (iGSH-CBT) for Bulimia Nervosa (BN) / Binge Eating Disorder (BED) for Japanese patients and to test its feasibility. METHODS: A single-arm feasibility study. After baseline assessment, patients underwent a 16-week iGSH-CBT program, our Japanese adaption of the European-based Salut BN program. During the treatment period, weekly email support from trained counselors was provided. Evaluations were performed at baseline, after 8 weeks, at the end of the 16-week intervention, and at 2 months after treatment had ended. The primary outcome measure was the change in the weekly frequency of objective binging. Secondary outcomes were the change in the weekly frequency of objective purge episodes, responses on self-report questionnaires of the frequencies of binging and purging, psychopathological characteristics of eating disorders found on BITE, EDE-Q, EDI-2, HADS and EQ-5D, measurements of motivation, and completion of intervention (vs. dropout). RESULTS: Participants were 9 female outpatients with BN (n = 5) or BED (n = 4), of whom 8 (88.9%) attended the assessment at the end of the 16-week intervention. Mean age was 28 years (SD = 7.9). Percent change of the weekly frequency of objective binging was -4.40%, and at the end of the 16-week intervention 25% of the participants had achieved symptom abstinence. CONCLUSIONS: No adverse events were observed during the treatment period and follow-up, and the implementation and operation of the program could be performed without any major problems, confirming the feasibility of iGSH-CBT for BN and BED for Japanese patients. Although no significant change was observed in the weekly frequency of objective binging, the abstinence rate from bulimic behaviors of those who completed the assessments was 25.0% at the end of treatment, and the drop-out rate was 11.1%. iGSH-CBT may be an acceptable and possibly even a preferred method of CBT delivery for Japanese patients with BN or BED, and our Japanese adaptation of Salut BN seems feasible.

RESUMEN

Antipsychotic medications are widely used in patients with delirium. However, antipsychotics may lead to various adverse events including cardiac arrythmias, extrapyramidal side effects, and oversedation. This study aimed to investigate whether non-antipsychotic medications including ramelteon, suvorexant, and trazodone are useful for the treatment of elderly inpatients with delirium in a general ward setting. This was a retrospective cohort study using medical chart reviews of all consecutive inpatients with hyperactive forms of delirium who were admitted to a regional general hospital. The primary outcome of this study was to evaluate whether non-antipsychotic medication (ramelteon, suvorexant, and trazodone) is inferior, in terms of efficacy and safety, to antipsychotic medication in delirium treatment. Of 154 patients who consulted psychiatrists during the study period, 33 patients were diagnosed with hyperactive delirium. Of these patients, 21 were categorized into the antipsychotic medication group, and 12 were categorized into the non-antipsychotic medication group. The duration of delirium after pharmacological treatments was not statistically different between the two groups. However, the rates of adverse events related to psychotropic medications in the antipsychotic medication group were significantly higher than that in the non-antipsychotic medication group. This study demonstrated that, in the treatment of elderly patients with delirium, non-antipsychotic drugs, such as suvorexant, ramelteon, and trazodone, could be more useful than antipsychotics in terms of efficacy and safety.

RESUMEN

OBJECTIVE: This study aimed to validate the Sick, Control, One stone, Fat, and Food (SCOFF) questionnaire in relation to the Eating Disorders Examination Questionnaire (EDE-Q) and to examine the appropriateness of a question concerning weight loss among Japanese university students. The psychometric properties of the two Japanese versions were determined among 649 Japanese college students. The original version (SCOFF-O) employed the original item 3, whereas the revised version (SCOFF-2.5) modified the item to "Have you recently lost more than 2.5 kg within three months?" Validity was tested relative to EDE-Q. RESULTS: The test-retest reliabilities of SCOFF-O and SCOFF-2.5 were 0.52 and 0.57, while the correlations of SCOFF-O and SCOFF-2.5 with EDE-Q were r = 0.53 and r = 0.56. The sensitivity and specificity of SCOFF-O were 65.2 and 89.7, and those of SCOFF-2.5 were 69.5 and 86.5, respectively. There were significant correlations between the question concerning losing 2.5 kg and the EDE-Q subscales. The Japanese version of SCOFF-2.5 is an appropriate tool for the early screening of eating disorders among Japanese university students.
