RESUMO
Painless thyroiditis, which is rare in children, exhibits the characteristic sequence of hyperthyroidism, including aggressive and disruptive behaviors. Unlike subacute thyroiditis or Graves' disease, painless thyroiditis is challenging to diagnose because of its mild symptoms and minimal or absent physical findings. Moreover, aggressive and disruptive behaviors in children with psychiatric disorders may be misconstrued as exacerbation of underlying symptoms. The present patient was a 16-year-old male with adjustment disorder who presented to a pediatric psychiatric clinic for assessment of irritability. After 4 months, he developed aggressive and disruptive behaviors that prompted initiation of risperidone but without improvement. After 1 month, he reported palpitations and dyspnea. His neck was supple and non-tender without thyroid enlargement. Thyroid studies revealed elevated free T4 and T3 levels and suppressed thyroid-stimulating hormone level, suggesting hyperthyroidism. A radioactive iodine uptake test revealed a barely visible thyroid gland, consistent with thyroiditis. Painless thyroiditis, without thyroid tenderness, was diagnosed. We describe a case of painless thyroiditis in an adolescent patient with aggressive and disruptive behaviors that were initially attributed to worsening of an underlying adjustment disorder. Even when minimal or no signs of hyperthyroidism are present, painless thyroiditis should be considered in the differential diagnosis of children with aggressive and disruptive behaviors. Awareness of potential anchoring bias is also recommended to prevent its delayed diagnosis of such behaviors.
RESUMO
BACKGROUND: The number of suicides in Japan decreased during the period from 2012 through 2019. Because data on factors associated with this decline are limited, we conducted a retrospective longitudinal study of psychiatric diagnoses of serious suicide attempters before 2012 and after 2019. METHODS: Serious suicide attempters admitted to the critical care medicine (CCM) department of Nippon Medical School Hospital between 2006 and 2017 were included and classified as those before and after the suicide decline in 2012. Chi-square test and residual analysis were used to analyze changes in the proportion of suicide attempters among all patients admitted to CCM and to examine differences in the proportion of psychiatric diagnoses. RESULTS: The proportion of suicide attempters among CCM hospitalized patients decreased overall (χ2 (1) =18.29, p<.01). The proportion of psychiatric diagnoses changed significantly (χ2 (8) =62.21, p<0.001); specifically, it decreased for schizophrenia (residual: -2.28), depressive disorders (residual: -5.39), persistent mood disorders (residual: -3.58), and reaction to stress disorders (residual: -2.73). Depressive disorders decreased and had a large contribution ratio in both sexes. CONCLUSIONS: The decrease in the proportion of attempted suicides among patients admitted to CCM was consistent with the decline in suicides in Japan. Analysis by psychiatric diagnosis confirmed a significant decrease in the proportion of suicide attempts associated with depressive disorders, schizophrenia, and reaction to stress disorders, which were the most common disorders associated with attempted suicide. Depressive disorders made the greatest contribution to the reduction in suicide attempts.

BACKGROUND: Connecting individuals in need of psychiatric treatment with adequate medical services has been a major strategy for suicide prevention in Japan. By investigating serious suicide attempters admitted to our Critical Care Medical Center (CCM), we aimed to examine longitudinal changes in the psychiatric treatment status of high-risk suicidal individuals, and to explore the association between any improvement in psychiatric treatment status and suicide decline. METHODS: Subjects from two periods, 2006-2011 and 2012-2017, were enrolled. We collected the data of 32,252 suicides in Tokyo from police reports and the data of 942 suicide attempters admitted to CCM from medical records. Data were annually collected by both age and gender for the number of suicide completers, the number of suicide attempters, and the psychiatric treatment rates, respectively. ANOVA and t-test were used to examine whether there were differences in the number of suicides and attempers between the two periods. The difference in psychiatric treatment rate between the two periods was examined by chi-square test. Additionally, we used Pearson's correlation coefficient to analyze any correlation between annual treatment rate and the number of suicide completers in subgroups with altered psychiatric treatment rates. RESULTS: The number of suicide attempters in the 20-39-year age group of decreased together with the number of suicides. Psychiatric treatment rates of male attempters aged 20-59 years improved significantly from 48.7 to 70.6% and this improvement correlated with a decrease in suicides. However, psychiatric treatment rates in the elderly, which have the highest number of suicides in both genders, did not improve and remain low. CONCLUSIONS: The number of suicide attempters, as well as that of suicides, decreased in Tokyo. Improvement of psychiatric treatment status in high-risk suicidal male adults may have contributed to the reduction of suicides in Tokyo. However, the continuing low rate of psychiatric treatment in the elderly is a pressing issue for future suicide prevention.

BACKGROUND: There is a shortage of empirical data concerning precipitating factors for suicides in Japan. The purpose of the present study was to clarify gender differences of precipitating factors for suicide attempts in Japan. METHODS: The subjects were high-lethality suicide attempters who were admitted to the Nippon Medical School Hospital Critical Care Medical Center between March 1, 2010 and March 31, 2012. Precipitating factors for suicide attempt, method of suicide attempt, psychiatric diagnoses and other sociodemographic data were collected from the patients' medical records retrospectively, and statistical analyses were performed for categorical variables of male/female. RESULTS: The total number of subjects was 193 (88 males and 105 females). The rate of subjects attempting suicide by poisonous gas was significantly higher in males while that of subjects attempting suicide by drug overdose was significantly higher in females. The rate of subjects diagnosed with "major depressive disorder, bipolar disorder" was significantly higher in males while that of subjects diagnosed with "personality disorders" or "dysthymic disorder" was significantly higher in females. Subjects with "health problems", "financial problems", "work problems", "debts (others)" or "unwanted transfer" were significantly more numerous among males; subjects with "family problems", "parent-child relations" or "loneliness" were significantly more frequently found among females. CONCLUSIONS: Mental disorders were the most common precipitating factor for suicide attempts regardless of gender. Significant gender differences were observed in psychiatric diagnoses, methods of suicide attempt and psychosocial problems. This indicates the necessity of suicide prevention measures corresponding to these gender differences.

BACKGROUND: Suicide is the leading cause of death among Japanese adolescents, and they may commit suicide differently from adults. However, there are few studies in medical-based data concerning adolescent patients seriously attempting suicide. We aimed to explore the characteristics of serious suicide attempts in Japanese adolescents, comparing them with those in adults. METHODS: We investigated adolescents who seriously attempted suicide and were treated at the Critical Care Medical Center (CCMC) of Nippon Medical School Hospital between 2000 and 2010, and we compared them with adult suicide attempters treated during 2009. We retrospectively studied medical records and collected clinical data and socio-demographic factors, including age, sex, psychiatric symptoms or diagnosis, methods of suicide attempt, motives for suicide attempt, previous deliberate self-harm, previous psychiatric history, parent loss experience, and previous psychiatric history in the family. RESULTS: Adolescent attempters were 15 males and 44 females, 13 to 18 years old (mean 16.39). Adult attempters were 37 males and 65 females, 19 to 79 years old (mean 39.45). In comparison to adult attempters, adolescent attempters were more frequently diagnosed with Borderline Personality Disorder (BPD), had more school problems and parent loss experience, but they had less financial problems. Gender differences between adolescents and adults were examined, and male adolescent attempters were found to be more frequently diagnosed with schizophrenia and had less financial problems than their adult counterparts, while female adolescent attempters were more frequently diagnosed with BPD, had more school problems and parent loss, but they had less previous psychiatric history than their adult counterparts. CONCLUSIONS: Our findings indicated that adolescent attempters were more frequently diagnosed with BPD and had more school problems and parent loss experience but had less financial problems. Additionally, in male adolescent attempters, identifying patients with schizophrenia seemed important, as it was their most frequent psychiatric diagnosis. For female adolescents, adequately assessing family function and interpersonal conflicts seemed important, as they were more often diagnosed with BPD and had more school and family problems.
