Psychiatric Features of Children with Chronic Functional Constipation: Focusing on Individuals with Autism Spectrum Disorder.

PURPOSE: The present study aimed to assess the psychiatric characteristics of children with chronic functional constipation using the Aberrant Behavior Checklist-Japanese version and the Pervasive Developmental Disorders/Autism Society Japan Rating Scale, and to examine the frequency of autism spectrum disorder in children with chronic functional constipation. We also investigated differences in treatment duration between children with and without autism spectrum disorder. METHODS: Treatment outcomes were examined retrospectively for 55 participants (chronic functional constipation group: n = 30, mean age 3.4 years; control group: n = 25, mean age, 4.5 years). The association between chronic functional constipation and autism spectrum disorder was evaluated using multivariable logistic regression analysis. RESULTS: The mean Aberrant Behavior Checklist score and frequency of individuals with autism spectrum disorder were significantly higher in the chronic functional constipation group. After adjusting for age and sex, chronic functional constipation was significantly associated with autism spectrum disorder. In the chronic functional constipation group, the frequency of onset was significantly higher in children with autism spectrum disorder under 1 year of age. When treated, the mean duration of constipation was significantly longer in children with autism spectrum disorder. CONCLUSION: Pediatricians, pediatric surgeons, and child psychiatrists should work closely to ensure appropriate treatment of chronic functional constipation in children with autism spectrum disorder.

Prescribing Patterns in Child and Adolescent Outpatient Psychiatry: A Retrospective Cohort Study of Prescriptions in the First Year.

OBJECTIVE: Recently, excessive and off-label prescribing of psychotropic drugs for children and adolescents have become a problem. Child and adolescent psychiatric patients receive treatment in many departments and department-specific psychotropic drug use has not been analyzed. We surveyed prescriptions for child and adolescent psychiatric outpatients during their first year of treatment. METHODS: The participants were 302 patients, 15 years or younger, who made their first visit to the outpatient psychiatry department of Tokai University Hospital from September 1, 2015 to September 1, 2016. Prescription details and patient profiles were retrospectively investigated using medical records. RESULTS: Medication was prescribed for 20.9% of patients (63/302) with the prescription rate increasing with age. Psychotropic drugs were prescribed for 15.6% of patients (48/302), with attention-deficit/hyperactivity disorder (ADHD) medications being most frequently prescribed (20 cases). Other than psychotropic drugs, iron pills (25 cases) and herbal medicines (21 cases) were prescribed frequently. CONCLUSIONS: The pharmacotherapy and psychotropic prescription rates were low. This may be due to the use of non-pharmacological interventions and the lack of inpatient facilities. With the publication of guidelines for pharmacotherapy in child psychiatry in Japan, measuring the patterns of psychotropic drug prescription in children and adolescents is important, and would make treatment more transparent.

Impact of Gut Microbiota on Host Aggression: Potential Applications for Therapeutic Interventions Early in Development.

Aggression in the animal kingdom is a necessary component of life; however, certain forms of aggression, especially in humans, are pathological behaviors that are detrimental to society. Animal models have been used to study a number of factors, including brain morphology, neuropeptides, alcohol consumption, and early life circumstances, to unravel the mechanisms underlying aggression. These animal models have shown validity as experimental models. Moreover, recent studies using mouse, dog, hamster, and drosophila models have indicated that aggression may be affected by the "microbiota-gut-brain axis." Disturbing the gut microbiota of pregnant animals increases aggression in their offspring. In addition, behavioral analyses using germ-free mice have shown that manipulating the intestinal microbiota during early development suppresses aggression. These studies suggest that treating the host gut microbiota during early development is critical. However, few clinical studies have investigated gut-microbiota-targeted treatments with aggression as a primary endpoint. This review aims to clarify the effects of gut microbiota on aggression and discusses the therapeutic potential of regulating human aggression by intervening in gut microbiota.

A Case of Nocturnal Enuresis Associated with Attention-deficit/hyperactivity Disorder Successfully Treated with Guanfacine Monotherapy.

Nocturnal enuresis (NE) is a syndrome associated with abnormal nocturnal urine production, urination mechanism, and sleep arousal. NE is strongly associated with attention-deficit/hyperactivity disorder (ADHD), and it has been reported that NE occurs in approximately 30% of children with ADHD. There have been several reports on the efficacy of atomoxetine as treatment for NE with ADHD, while the efficacy of guanfacine is still limited. We report our experience of treating an 10-year-old girl with NE with ADHD with a single dose of guanfacine. The patient first visited our hospital because of difficulty concentrating, restlessness at home and school, and nocturnal incontinence. She was diagnosed with NE with ADHD based on a review of her personal history from her mother. Her NE symptoms improved with guanfacine monotherapy (1 mg/day. The patient weighed 28 kg).

Iron Supplementation for Hypoferritinemia-Related Psychological Symptoms in Children and Adolescents.

BACKGROUND: Although some studies have described the association between serum ferritin levels and specific disorders in child and adolescent psychiatry, few have focused on mental status per se with low serum ferritin levels in children and adolescents. This study examined the effects of iron administration on psychological status of children and adolescents with reduced serum ferritin concentration. METHODS: This prospective study evaluated 19 participants aged 6-15 years with serum ferritin levels <30 ng/mL who visited a mental health clinic and received oral iron administration for 12 weeks. The participants were assessed using the Clinical Global Impression Severity (CGI-S), Profile of Mood States 2nd Edition Youth-Short (POMS), Center for Epidemiologic Studies Depression Scale (CES-D), and Pittsburgh Sleep Quality Index (PSQI). In addition to serum ferritin, blood biochemical values such as hemoglobin (Hb) and mean corpuscular volume (MCV) were examined. School attendance was recorded. RESULTS: The most prevalent physical symptoms were fatigability and insomnia. The CGI-S, PSQI, and CES-D scores decreased significantly following iron supplementation, whereas the scores of almost all POMS subscales improved significantly at week 12. No participant had hemoglobin levels <12 g/dL. Serum ferritin concentration increased significantly, whereas Hb and MCV remained unchanged. At baseline, 74% of the participants did not attend school regularly; this number improved to varying degrees by week 12. CONCLUSIONS: Serum ferritin levels would be preferable to be measured in children and adolescents with insomnia and/or fatigability regardless of psychiatric diagnoses or gender. Iron supplementation can improve the hypoferritinemia-related psychological symptoms of children and adolescents, such as poor concentration, anxiety, depression, low energy and/or irritability.

Effect of gut microbiota early in life on aggressive behavior in mice.

Recent reports have indicated that gut microbiota modulates the responses to stress through the microbiota-gut-brain axis in mice, suggesting a connection between gut microbiota and brain function. We hypothesized that the gut microbiota early in life would have an effect on aggressiveness, and examined how gut microbiota affect aggressive behaviors in mice. BALB/c mice were housed in germ-free (GF) and ex-germ-free (Ex-GF) isolators. An aggression test was performed between castrated and a non-castrated mice at 8 weeks of age; the mice were allowed to confront each other for 10 min in strictly contamination-free environments. To evaluate aggressive behavior related to gut microbiota, we orally administered diluted Ex-GF mouse feces to the offspring of GF mice at 0, 6, and 10 weeks. GF mice showed more aggression than Ex-GF mice. Furthermore, GF mice who were administered feces of the Ex-GF group at 0-week-old were less aggressive than the GF mice. These findings suggested that the gut microbiota in the early stages of development was likely to have an effect on aggressiveness. Maintenance of healthy gut microbiota early in life can affect the mitigation of aggressive behavioral characteristics throughout the lifetime.

Effective Tools to Predict Depression in Acute and Subacute Phase of Ischemic Stroke.

OBJECTIVE: Despite the high frequency of depression in the first year following stroke, few studies have predicted risk of depression after the acute and subacute stroke periods. The aim of this study was to identify, in the acute and subacute periods, measures that would predict major depression during the first year after stroke. METHODS: Study subjects were inpatients with ischemic stroke aged 20-85 years within 6 weeks of onset. Patients were evaluated at baseline and at 3, 6, 9, and 12 months. Patients were diagnosed with major depression using the Structured Clinical Interview for DSM-IV. The severity of depressive symptoms was measured with the Patient Health Questionnaire-9 (PHQ-9) and the Montgomery-Åsberg Depression Rating Scale (MADRS). RESULTS: Of the 152 potential patients who met inclusion criteria, 49 had follow-up evaluations; one patient with major depression in the acute and subacute periods was excluded from the analysis. Among the remaining 48 patients, the number of those with major depression during the first year of stroke onset was five (10.4%). Patients who developed major depression had significantly more depressive symptoms in the acute and subacute stroke phase as assessed by both the PHQ-9 and MADRS. Patients with PHQ-9 scores ≥9 in the acute and subacute stroke phases were significantly more likely to develop major depression in a chronic phase of stroke. CONCLUSIONS: The self-administered PHQ-9 can identify patients in the acute and subacute stroke periods who are at increased risk for developing major depression during the first year after stroke.

Second-Generation Antipsychotic Drugs for Children and Adolescents.

The effectiveness and safety of antipsychotics have not been fully established in children and adolescents. Many antipsychotics approved for use in adults are prescribed off-label to children and adolescents. We investigated the effectiveness and tolerability of antipsychotics for children and adolescents with schizophrenia and bipolar disorder. A literature review of the empirical evidence regarding the use of antipsychotics, particularly second-generation antipsychotics, in children and adolescents showed that these drugs were safe and effective for this population. Antipsychotics were similarly effective for treatment of schizophrenia and bipolar disorder in children and adolescents. When prescribing antipsychotics to this population, clinicians should consider adverse events and the discontinuation rate in treated patients. However, the current evidence shows a lack of consensus regarding the use of antipsychotics in children and adolescents.

Efficacy of Mirtazapine on Irritable Bowel Syndrome with Anxiety and Depression: A Case Study.

Irritable bowel syndrome (IBS) is a disease in which gastrointestinal symptoms-primarily abdominal pain or discomfort and abnormal bowel movements persist chronically. For patients with IBS, mental illness, especially depression and/or anxiety, leads to a further lower quality of life. The purpose of this case study was to investigate the effects of mirtazapine (MIR) on mental health and IBS symptoms in a case of IBS accompanied by anxiety and a depressive state. This case report suggests that MIR is efficacious for the treatment of IBS with predominant diarrhea accompanied by depression and anxiety.

Frequency and clinical features of patients who attempted suicide by Hara-Kiri in Japan.

Hara-kiri is a unique Japanese custom, primarily stemming from the manners and customs that a samurai held. The aim of the present study was to investigate the clinical features of individuals who attempted suicide by hara-kiri. We enrolled 647 patients who had attempted suicide. Clinical features were compared between those who had employed hara-kiri and those who had used other methods. 25 of the 647 subjects had attempted suicide by hara-kiri. The ratio of men to women and the proportion of patients with mood disorders were significantly higher in the hara-kiri group than in the other methods group. The average length of stay in either the hospital or in the intensive care unit was also longer in the hara-kiri group than in the other methods group. Hara-kiri is an original Japanese method of attempting suicide, and suicide attempts by hara-kiri may be aimed at maintaining a reputation or taking responsibility.

Changes in the frequency and clinical features of suicide attempts in the midwestern area of Kanagawa after the great East Japan earthquake.

The aim of this study was to investigate the relationship between the clinical features of suicide attempts and the Great East Japan earthquake in Kanagawa. We enrolled 592 patients who attempted suicide and were hospitalized for inpatient treatment. Clinical features were compared between before the earthquake (A) and after the earthquake (B) groups. The number of suicide attempts increased from 286 to 306. The rate of increase in suicide attempts in men was the highest in the age group of 40-59 years. The frequency of joblessness, family psychiatric histories, precipitating event, and alcohol intake at suicide attempt was significantly higher in the B group than in the A group. The number of patients in serious condition in the B group was significantly higher than that in the A group. Other clinical features related to suicide in people who were indirectly affected by the earthquake disaster should be investigated to develop targeted prevention strategies.

[Childhood-onset schizophrenia].

Childhood-onset schizophrenia has been clinically studied and is believed to be on a continuum with adult-onset schizophrenia. However, childhood-onset schizophrenia is more difficult to diagnose than it is in adults, since children are in a developmental state. This article reviewed the literature regarding childhood-onset schizophrenia. This article discusses the clinical features, development until manifestation, possibility of early diagnosis, and treatment. Early intervention may improve the prognosis of psychotic disorders such as schizophrenia. However, early intervention of childhood-onset schizophrenia requires case histories with accurate descriptions of the development of the disease until its onset.

Frequency and clinical features of suicide attempts in elderly patients in Japan.

The objective of this study was to investigate the clinical features of suicide attempts in elderly patients (≥65 years) in Japan. We enrolled 546 patients who attempted suicide and were hospitalized for inpatient treatment. Characteristics were compared between the elderly and non-elderly patients. Compared with the non-elderly group, the incidence of mood disorders was significantly higher and the average length of stay in the intensive care unit and the duration of hospitalization were significantly longer in the elderly group. Elderly patients hospitalized for attempted suicide were more likely to have mood disorders than the non-elderly.

Clinical features of suicide attempts in adults with autism spectrum disorders.

OBJECTIVE: The objective of this study was to investigate the frequency and clinical features of suicide attempts in adults with autism spectrum disorders (ASDs). METHODS: We enrolled 587 consecutive patients aged 18 or over who attempted suicide and were hospitalized for inpatient treatment. Psychiatric diagnoses, suicide attempt frequency and clinical features were compared between ASD and non-ASD patients. RESULTS: Forty-three (7.3%) of the 587 subjects who attempted suicide had ASDs. The incidence of patients with mood disorders was significantly lower (Fisher's Exact Test, P=.043) and that of those with an adjustment disorder was significantly higher (Fisher's Exact Test, P<.001) in the ASD group than in the non-ASD group. The average length of stay at both the hospital and intensive care unit in the ASD group was longer than that in the non-ASD group (z=-2.031, P=.042; z=-2.322, P=.020, respectively). CONCLUSIONS: ASDs should always be a consideration when dealing with suicide attempts in adults at the emergency room.

Frequency and clinical features of patients who attempted suicide by charcoal burning in Japan.

BACKGROUND: To date, the clinical features between patients in Japan who have attempted suicide by charcoal burning and those who have attempted suicide by other methods in the context of a mental disorder diagnosis as assessed by structured interviews have not been reported. METHODS: We enrolled 647 consecutive patients who attempted suicide and were hospitalized for inpatient treatment. Psychiatric diagnoses, frequency of suicide attempts, and clinical features were compared between charcoal burning and other suicide methods. RESULTS: Twenty of the 647 patients (3.1%) had attempted suicide by charcoal burning. The ratio of men to women was significantly higher by this method compared with that of other methods. The proportion of patients with mood disorders was significantly higher in the charcoal burning group than that in the other methods group. The occurrence of a psychiatric history in patients in the charcoal burning group was significantly lower than that in the other methods group. LIMITATIONS: The study sample was limited to a single hospital. CONCLUSIONS: The results demonstrate the clinical characteristics of patients who attempted suicide by charcoal burning. Therefore, it is necessary to identify the clinical features of patients who have attempted suicide by charcoal burning in Japan.
