RESUMO
The present study examined how maltreatment experience was associated with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) symptoms in children under institutional care. The key caregivers of children and adolescents aged 6 to 18 years who were under institutional care in Nagano prefecture, Japan were asked to answer the background questionnaire, ADHD-Rating Scale, and the Japanese children's version of the Autism-Spectrum Quotient. A total of 378 valid responses were obtained, of which 222 reported maltreatment experience prior to institutionalization. Both hyperactive/impulsive and inattentive scores were significantly higher in the maltreated group. Maltreatment experience was significantly associated with the presence of hyperactive/impulsive symptoms (p = 0.003) and inattentive symptoms (p = 0.027). Particularly, those who had experienced physical abuse were significantly more likely to have hyperactive/impulsive symptoms (p = 0.012) and autistic trait (p = 0.002). Thorough assessment of neurodevelopmental symptoms should be performed when placing children with maltreatment experience into institutional care.

AIM: The aim of this clinical trial was to obtain proof of concept for high-dose pyridoxamine as a novel treatment for schizophrenia with enhanced carbonyl stress. METHODS: Ten Japanese schizophrenia patients with high plasma pentosidine, which is a representative biomarker of enhanced carbonyl stress, were recruited in a 24-week, open trial in which high-dose pyridoxamine (ranging from 1200 to 2400 mg/day) was administered using a conventional antipsychotic regimen. Main outcomes were the total change in Positive and Negative Syndrome Scale score and the Brief Psychiatric Rating Scale score from baseline to end of treatment at week 24 (or at withdrawal). RESULTS: Decreased plasma pentosidine levels were observed in eight patients. Two patients showed marked improvement in their psychological symptoms. A patient who harbors a frameshift mutation in the Glyoxalase 1 gene also showed considerable reduction in psychosis accompanied with a moderate decrease in plasma pentosidine levels. A reduction of greater than 20% in the assessment scale of drug-induced Parkinsonism occurred in four patients. Although there was no severe suicide-related ideation or behavior, Wernicke's encephalopathy-like adverse drug reactions occurred in two patients and were completely suppressed by thiamine supplementation. CONCLUSION: High-dose pyridoxamine add-on treatment was, in part, effective for a subpopulation of schizophrenia patients with enhanced carbonyl stress. Further randomized, placebo-controlled trials with careful monitoring will be required to validate the efficacy of high-dose pyridoxamine for these patients.

Our previous study showed that enhanced carbonyl stress is closely related to schizophrenia. The endogenous secretory receptor for advanced glycation end-products (esRAGE) is a splice variant of the AGER gene and is one of the soluble forms of RAGE. esRAGE is considered to be a key molecule for alleviating the burden of carbonyl stress by entrapping advanced glycation end-products (AGEs). In the current study, we conducted genetic association analyses focusing on AGER, in which we compared 212 schizophrenic patients to 214 control subjects. We also compared esRAGE levels among a subgroup of 104 patients and 89 controls and further carried out measurements of total circulating soluble RAGE (sRAGE) in 25 patients and 49 healthy subjects. Although the genetic association study yielded inconclusive results, multiple regression analysis indicated that a specific haplotype composed of rs17846798, rs2071288, and a 63 bp deletion, which were in perfect linkage disequilibrium (r2 = 1), and rs2070600 (Gly82Ser) were significantly associated with a marked decrease in serum esRAGE levels. Furthermore, compared to healthy subjects, schizophrenia showed significantly lower esRAGE (p = 0.007) and sRAGE (p = 0.03) levels, respectively. This is the first study to show that serum esRAGE levels are regulated by a newly identified specific haplotype in AGER and that a subpopulation of schizophrenic patients are more vulnerable to carbonyl stress.

OBJECTIVES: Students' depressive symptoms might be related to their own risk factors and to their parents' status. The objective of this cross-sectional study was to examine the relationship of depressive symptoms with lifestyle variables and parents' psychological and socio-demographic status among Japanese junior high school students. METHODS: Of 477 students and their parents, 409 (85.7 %) students and 314 (65.8 %) parents participated in the study. Students answered self-reported questionnaire on depressive symptoms, their heights and weights, subjective stress, body dissatisfaction, lifestyles including sleep duration and extracurricular physical activity in school and other physical activity outside the school, and nutritional intake. Parents responded to questionnaire on depressive symptoms and socio-demographic status. RESULTS: The prevalence of depressive symptoms was 24.9 %. Students with depressive symptoms were more likely to have stress. Students in shorter and longer sleep duration groups were more likely to have depressive symptoms. The students with depressive symptoms had smaller amount of energy intake than did those without depressive symptoms. Multiple logistic regression analysis revealed significant relationships between students' depressive symptoms and some independent variables. Sex, subjective stress, "almost-never"-categorized extracurricular physical activity in school and other physical activity outside the school, and having a parent with depressive symptoms were significantly associated with students' depressive symptoms. CONCLUSION: Reducing mental stress and taking care of lifestyles, especially, "almost-everyday"-categorized extracurricular physical activity in school and other physical activity outside the school, may have benefits for students' mental health, and having a parent with depressive symptoms may be associated with students' depressive symptoms.

OBJECTIVES: Feeling ashamed for seeking help when distressed is known to be a critical factor promoting suicidal behaviors. The objective of this study was to examine the relationship between suicidal ideation and psychosocial factors, including worries or anxieties, having a person to confide in, feeling ashamed for seeking help when distressed, and K6 score. METHODS: Fourteen out of 77 municipalities from Nagano Prefecture participated in this questionnaire survey. Participants of both sexes over 20 years of age were randomly selected according to age distribution in each municipality. Association between suicidal ideation and sociodemographic and psychosocial factors, including "feeling ashamed for seeking help", were determined by multiple logistic regression analysis. RESULTS: Among a total of 11,100 participants, 7394 (66.6%) returned the questionnaire. 2147 participants responded properly to essential study parameters and were submitted to the final analyses. The adjusted odds ratio of suicidal ideation was 2.09 (95% CI 1.49-2.94) among participants feeling ashamed for seeking help, compared to those not feeling ashamed. Although the rate of "no person to confide in" was 4.4%, participants who responded with "no person to confide in" had significantly increased odds ratio of suicidal ideation compared with those who responded with "having a person to confide in" (OR 1.97, 95% CI 1.12-3.47). CONCLUSIONS: Our findings suggest a need for tailored intervention targeting individuals at risk by gatekeepers to encourage individuals at risk to overcome feeling ashamed for seeking help and to cultivate an appropriate person to confide in.

We report on two elderly patients with cognitive impairments, for whom chronic carbon monoxide (CO) exposure was suspected based on elevated carboxyhaemoglobin levels in their serum. On their initial visits, cognitive impairment and brain magnetic resonance imaging findings in both patients were compatible with the diagnosis of Alzheimer's-type dementia. However, after discontinuation of the use of a kotatsu, a charcoal-based heater, their serum carboxyhaemoglobin levels normalized and their physical symptoms resolved. Their cognitive function also slightly improved. The causal relationship between physical symptoms and cognitive impairment after chronic CO poisoning is uncertain; however, it is possible that chronic exposure to low CO levels exacerbated the clinical manifestation in our patients.

AIM: This study investigated whether the characteristic changes in hippocampal atrophy seen in coronal scans are useful for differentiating Alzheimer's disease (AD), amnestic mild cognitive impairment (aMCI), and major depressive disorder (MDD). METHODS: Subjects included 58 patients with AD, 33 with aMCI, 20 with MDD, and 22 normal controls, all aged 60 years or older. For each subject, eight coronal short TI inversion recovery images perpendicular to the hippocampal longitudinal axis were obtained. Images were manually measured using the conventional region of interest method of quantitative analysis. RESULTS: The overall trend in the corrected volumes of the hippocampus was AD < aMCI < MDD < normal controls. We found atrophy in all slices in AD, atrophy centred on the hippocampal head in aMCI, and atrophy in the slice of the hippocampal body 12 mm from the amygdala in MDD. CONCLUSIONS: The present study suggested that our method of comparing hippocampal atrophy by region may be useful in distinguishing AD, aMCI, MDD, and normal controls.

BACKGROUND: When treating mentally ill criminal offenders, improving medication adherence is essential to achieving goals, such as long-term stabilization of symptoms and the prevention of recidivism. Most subjects who are treated under the Medical Treatment and Supervision Act have schizophrenia, which is considered a particularly difficult disorder for which to improve medication adherence. For such patients, we developed a Medication Discontinuation Program (MDP) that aims to improve medication adherence by discontinuing antipsychotic drugs and monitoring changes in psychiatric symptoms. We examined whether there was any utility for the MDP on a trial basis as well as whether it would be worthwhile to introduce the MDP to psychiatric programs. METHODS: We conducted the MDP with an intervention group (n = 7) and compared Drug Attitude Inventory-30 (DAI-30) scores before and after implementation of the MDP. We also categorized 30 questions of the DAI-30 into three subscales: "awareness of the need for medication", "awareness of the effects of psychiatric drugs", and "impression of medication", and examined factors affecting improvement in medication adherence. RESULTS: The total DAI-30 score significantly increased after completion of the MDP (P = 0.002). Significant elevations after completion of the MDP were also observed in the scores for three subscales of the DAI-30. CONCLUSIONS: Our study suggests that the MDP has a possibility of improving medication adherence, and this program might have multidirectional and stimulatory effects on each factor related to the improvement of medication adherence.

BACKGROUND: Patients with Alzheimer's disease (AD) often present with apathy symptoms resembling the decreased motivation observed in depressed patients. Therefore, differentiating the initial phase of AD from late life depression may be difficult in some cases. Near-infrared spectroscopy (NIRS) is a functional neuroimaging modality that uses near-infrared light to measure changes in hemoglobin concentration on the cortical surface during activation tasks. The objective of this study was to investigate differences in brain activation associated with late life depression and with AD by means of NIRS. METHODS: NIRS was performed in 30 patients with depression, 28 patients with AD, and 33 healthy controls, all aged 60 years or older. During two tasks, a verbal fluency task and a visuospatial task, changes in oxygenated hemoglobin concentration in the frontal and parietal cortices were investigated. RESULTS: In the visuospatial task, cortical activation was lower in the depressed group than in the AD group, and significant differences were observed in the parietal cortex. CONCLUSIONS: NIRS can detect differences in brain activation between patients with late life depression and those with AD. NIRS is a promising tool for the differential diagnosis of late life depression and AD.

The pandemic influenza A/H1N1 2009 virus is commonly known to affect younger individuals. Several epidemiological studies have clarified the epidemic features of university students in Japan. In this study, we reviewed these studies in Japan in comparison with reports from other countries. The average cumulative incidence rate among university students was 9.6 %, with the major symptoms being cough, sore throat, and rhinorrhea. These epidemiological features were similar between Japan and other countries. Attitudes and behaviors toward pandemic influenza control measures were different before and improved during and after the epidemic. These features were also similar to those in other countries. On the other hand, the epidemic spread through club activities or social events, and transmission was attenuated after temporary closure of such groups in Japan. This transmission pattern was inconsistent among countries, which may have been due to differences in lifestyle and cultural habits. Based on these results, infection control measures of pandemic influenza for university organizations in Japan should be considered.

Lemborexant, an orexin receptor antagonist, is effective not only for sleep disorders but also for preventing and treating delirium. To date, no complex sleep-related behaviors due to lemborexant have been reported. Herein, we present the case of a 69-year-old male patient who was hospitalized for oral floor and tongue cancer and developed delirium after surgery; however, upon lemborexant dosage increase, used to treat insomnia, he developed abnormal nocturnal behavior. This symptom rapidly improved when lemborexant was discontinued. Distinguishing parasomnia from delirium is important because the treatment of these two conditions differs. Although rapid eye movement sleep behavior or sleepwalking was the cause of this parasomnia, a definitive diagnosis could not be established. If qualitatively distinct abnormal behavior is observed compared to delirium after increasing lemborexant dosage, the possibility of parasomnia should be considered.
RESUMO
The incidence of major depressive disorder (MDD) after heart transplantation is high; however, there are no reports on treatment options when antidepressant therapy fails to improve the condition. We herein report on the case of a woman with MDD after heart transplantation who partially improved with antidepressant treatment but continued to have a loss of appetite. Augmentation treatment with aripiprazole improved her appetite, and her MDD went into remission. When antidepressant treatment is not sufficiently effective for MDD after heart transplantation, augmentation treatment with antipsychotics, such as aripiprazole, should be considered.
RESUMO
Background: Restless legs syndrome (RLS) is a neurological sensorimotor disorder characterized by an uncontrollable urge to move the legs. In the perioperative period, patients with RLS may experience an acute exacerbation of symptoms. Although studies on the exacerbation of RLS after brain surgery are limited, we present a case wherein symptoms worsened following left amygdalohippocampectomy. Case Presentation: A 58-year-old woman diagnosed with mesiotemporal lobe epilepsy accompanied by left hippocampal sclerosis underwent a left amygdalohippocampectomy. The patient reported uncomfortable sensations in the lower limbs preoperatively. However, the urge to move her legs was manageable and not distinctly diagnosed with RLS. The symptoms began to deteriorate on the fifth postoperative day primarily affecting the legs and back, with a notable emphasis on the right side. Pramipexole treatment effectively ameliorated these symptoms. Conclusion: No reports are available highlighting the exacerbation of RLS after amygdalohippocampectomy. Perioperative factors, such as anesthesia and iron deficiency due to hemorrhage, have been proposed as aggravating factors for RLS; however, the asymmetry of RLS, particularly the atypical right-sided exacerbation in this case, makes it unlikely that this was the primary cause. A negative correlation between opioid receptor availability in the amygdala and RLS severity has been reported, suggesting that amygdalohippocampectomy contributes to the exacerbation of RLS symptoms. This case provides valuable insights into the possible involvement of the amygdala in the pathophysiology of RLS and practical considerations for the clinical management of the condition.
RESUMO
Although the natural history of H1N1 has been found to vary among patients, little is known about the factors that affect these variations. Infected patients with an extended infection history may shed virus longer and spread infection. To further clarify these variations, we evaluated the natural history of H1N1 infection in 324 university students using a descriptive epidemiological method and analyzed factors affecting the natural history of infection. The median times from infection to fever development and from fever development to cure were 2 days (range 0-8 days) and 5 days (range 1-12 days), respectively, and the median time not attending classes was 5 days (range, 1-13 days). Variations in H1N1 natural history were associated with both environmental and individual factors, including route of infection, grade, gender, epidemic period, respiratory and gastrointestinal symptoms and headache. Steps affecting these factors may help control variations in H1N1 natural history and may enhance infection control measures.

Associations between large cavum septum pellucidum and functional psychosis disorders, especially schizophrenia, have been reported. We report a case of late-onset catatonia associated with enlarged CSP and cavum vergae. A 66-year-old woman was presented with altered mental status and stereotypic movement. She was initially treated with aripiprazole and lorazepam. After 4 weeks, she was treated with electroconvulsive therapy. By 10 treatments, echolalia vanished, and catatonic behavior was alleviated. Developmental anomalies in the midline structure may increase susceptibility to psychosis, even in the elderly.

Idiopathic abnormal bodily sensations, or cenesthesic symptoms, are exhibited in a wide variety of mental illnesses. In Japan, patients with abnormal bodily sensations are often diagnosed with cenesthopathy. This study reviewed recent case reports of cenesthopathy. Of the 100 identified cases, young patients were more commonly men with predominant bodily cenesthesic symptoms, while older patients (≥40 years) were more commonly women with cenesthesic symptoms restricted to the oral cavity (oral cenesthopathy).
