No Associations of Psychological Symptoms and Suicide Risk with Disaster Experiences in Junior High School Students 5 Years After the 2011 Great East Japan Earthquake and Tsunami.

INTRODUCTION: Natural disasters such as earthquakes can cause substantial damage and trauma, especially to children. The aim of this study was to examine the effects of disaster experience on psychological symptoms, suicide risk, and associated factors in junior high school students 5 years after the Great East Japan Earthquake (GEJE). The hypothesis of this study was that psychological symptoms and suicide risk of junior high school students are associated with disaster experience. METHODS: A cross-sectional survey consisting of questionnaires and face-to-face interviews with students at two junior high schools in Ishinomaki city, Miyagi Prefecture, Japan, about psychological symptoms, disaster situations, and their current environment 5 years after the GEJE was conducted. In total, data from 264 (117 boys [44.3%] and 147 girls [55.7%]) students were analyzed. RESULTS: There were no associations between disaster experience and PTSSC-15, DSRS-C, and SCAS scores. Those with evacuation experience and still living in temporary housing had significantly higher scores on the oppositional defiant behavior inventory (ODBI). Of these students, 29 (11.0%) were considered to have suicide risk 5 years after the GEJE. The presence of depressive symptoms was the only factor related to suicide risk; no associations were found with sex, post-traumatic stress disorder (PTSD) symptoms, or other factors reported in previous studies, including disaster experience. CONCLUSIONS: Disaster experience was not associated with psychological symptoms (PTSD, depression, anxiety) and suicide risk in junior high school students 5 years after the GEJE. The suicide risk appears to be the same as that in the general population in Japan. However, attention should be paid to externalization problems and depressive symptoms, an important suicide risk factor, even 5 years after the GEJE.

Current situation and challenges for mental health focused on treatment and care in Japan and the Philippines - highlights of the training program by the National Center for Global Health and Medicine.

BACKGROUND AND PURPOSE: Mental health has emerged as an important public health concern in recent years. With a high proportion of children and adolescents affected by mental disorders, it is important to ensure that they are provided with proper care and treatment. With the goal of sharing the activities and good practices on child and adolescent mental health promotion, care, and treatment in Japan and the Philippines, the National Center for Global Health and Medicine conducted a training program on the promotion of mental health focused on treatment and care in Japan and the Philippines in September and November 2019. KEY HIGHLIGHTS: The training program comprised of a series of lectures, site visits, and round table discussions in Japan and the Philippines. The lectures and site visits focused on the current situation of child and adolescent psychiatry, diagnosis of childhood mental disorders, abuse, health financing for mental disorders, pharmacotherapy, psychotherapy, and disaster child psychiatry in both countries. Round table discussions provided an opportunity to explore the similarities and differences between the two countries in terms of the themes discussed during the lectures.The training program identified the need to collaborate with other professionals to improve the diagnosis of mental disorders in children and adolescents and to increase the workforce capable of addressing mental health issues among children and adolescents. It also emphasized the importance of cooperation between government efforts during and after disasters to ensure that affected children and their families are provided with the care and support that they need.

Did kindergarteners who experienced the Great East Japan earthquake as infants develop traumatic symptoms? Series of questionnaire-based cross-sectional surveys: A concise and informative title: traumatic symptoms of kindergarteners who experienced disasters as infants.

BACKGROUND: The Great East Japan Earthquake (GEJE) and tsunami of March 11, 2011 left behind many survivors, including children. This study aimed to assess changes in traumatic symptoms with time among kindergarteners who experienced GEJE as infants and to discuss the relationship between these symptoms and the disaster experience. METHODS: The 15-item Post-Traumatic Stress Symptoms for Children (PTSSC-15) questionnaire were distributed to the parents of kindergarteners (children aged 4-5 years) at 8, 20, 30, and 42 months after GEJE. Questionnaires regarding environmental damage conditions affecting the children were distributed to teachers 8 months after the tsunami. RESULTS: The number of kindergarteners was 262, 255, 236, and 202 at 8, 20, 30, and 42 months after the disaster. The PTSSC-15 total score was not different between kindergartners with and without environmental damage conditions. After 8 and 20 months, the PTSSC-15 total score of children who usually ate breakfast was significantly higher than that of children who did not. Moreover, after 30 and 42 months, the PTSSC-15 total score of kindergarteners who usually ate breakfast was not significantly higher than that of kindergarteners who did not. CONCLUSIONS: The traumatic symptoms of kindergarteners were not related to disaster experiences.

Effects of testosterone therapy on bipolar disorder with Klinefelter syndrome.

Klinefelter syndrome (KS) is widely associated with cognitive impairment and language problems. KS patients may also exhibit psychiatric symptoms. We present the case of an 18-year-old man with KS who experienced rapidly repeating relapses of manic episodes. He was unresponsive to the usual pharmacotherapies for bipolar disorders such as mood stabilizers and second-generation antipsychotics. Mood was eventually improved with testosterone therapy in addition to pharmacotherapy, with no relapse of manic episodes for 3 years after discharge. Testosterone therapy may prevent relapsing manic episodes of bipolar disorder in patients with KS.

[Quantitative evaluation of Gd-EOB-DTPA uptake in phantom study for liver MRI].

Gd-EOB-DTPA is a new liver specific MRI contrast media. In the hepatobiliary phase, contrast media is trapped in normal liver tissue, a normal liver shows high intensity, tumor/liver contrast becomes high, and diagnostic ability improves. In order to indicate the degree of uptake of the contrast media, the enhancement ratio (ER) is calculated. The ER is obtained by calculating (signal intensity (SI) after injection-SI before injection) / SI before injection. However, because there is no linearity between contrast media concentration and SI, ER is not correctly estimated by this method. We discuss a method of measuring ER based on SI and T(1) values using the phantom. We used a column phantom, with an internal diameter of 3 cm, that was filled with Gd-EOB-DTPA diluted solution. Moreover, measurement of the T(1) value by the IR method was also performed. The ER measuring method of this technique consists of the following three components: 1) Measurement of ER based on differences in 1/T(1) values using the variable flip angle (FA) method, 2) Measurement of differences in SI, and 3) Measurement of differences in 1/T(1) values using the IR method. ER values calculated by these three methods were compared. In measurement made using the variable FA method and the IR method, linearity was found between contrast media concentration and ER. On the other hand, linearity was not found between contrast media concentration and SI. For calculation of ER using Gd-EOB-DTPA, a more correct ER is obtained by measuring the T(1) value using the variable FA method.

Semiautomated volumetry of the cerebrum, cerebellum-brain stem, and temporal lobe on brain magnetic resonance images.

PURPOSE: The aim of this study was to develop an automated method of segmenting the cerebrum, cerebellum-brain stem, and temporal lobe simultaneously on magnetic resonance (MR) images. METHODS AND MATERIALS: We obtained T1-weighted MR images from 10 normal subjects and 19 patients with brain atrophy. To perform automated volumetry from MR images, we performed the following three steps: (1) segmentation of the brain region; (2) separation between the cerebrum and the cerebellum-brain stem; and (3) segmentation of the temporal lobe. Evaluation was based on the correctly recognized region (CRR) (i.e., the region recognized by both the automated and manual methods). RESULTS: The mean CRRs of the normal and atrophic brains were 98.2% and 97.9% for the cerebrum, 87.9% and 88.5% for the cerebellum-brain stem, and 76.9% and 85.8% for the temporal lobe, respectively. CONCLUSION: We introduce an automated volumetric method for the cerebrum, cerebellum-brain stem, and temporal lobe on brain MR images. Our method can be applied to not only the normal brain but also the atrophic brain.

Optimal timing of MR sialography by use of a simple method of stimulating the salivary gland: a preliminary report.

The present study was performed for determining the optimal timing of MR sialography by use of the Japanese pickled plum (umeboshi) for promoting secretion by the salivary glands. MR sialography was performed in four healthy male volunteers. The four volunteers were examined before and 10 min after stimulation with umeboshi. On the next examination, three volunteers were examined before and after umeboshi stimulation every 1 min up to 5 min to allow assessment of the temporal changes in duct visualization. Dilatation of the salivary gland ducts and improvement of the visualization of the ducts were obtained after stimulation with umeboshi. The difference in the dilatation of the parotid duct was statistically significant. In the temporal study, the salivary gland ducts were shown to be dilated at 2 min after stimulation. As a result, 2 min after stimulation is the optimal timing for MR sialography by use of umeboshi as a stimulator of salivary secretion.

[Basic and clinical studies of visualizing right inferior phrenic artery by multi detector row-CT].

To perform transcatheter arterial embolization (TAE) successfully, it is important to obtain information about parasitic arterial supply to the hepatocellular carcinoma (HCC). Among these extrahepatic collateral vessels, the right inferior phrenic artery (RIPA) is the most frequent and important extrahepatic collateral artery supplying the HCC. In the present study, we obtained multi-planar reformation (MPR) images of RIPA using multi detector row computed tomography (MDCT), assessed the ability of MDCT to demonstrate the origin of RIPA, and then analyzed the morphology of the origin. In a basic study using an original phantom simulating vessel origin, the origin was poorly visualized depending on the phantom diameter and angle of the origin to the scanned section. A clinical study was performed in 28 patients with HCC who underwent both MDCT and angiography within a short period. In 19 of 28 patients, RIPA originated at the celiac artery. In 3 patients, RIPA originated at the right renal artery, and in 6, directly at the abdominal aorta. The origin of RIPA was categorized into four patterns according to the inclination of the origin on transverse sections of MDCT. RIPA that originated at the right renal artery and showed an upward course perpendicular to the scan section of MDCT were most clearly visualized at the origin. In addition, RIPA could be observed in an optional direction on the workstation. Pre-angiographic visualization of the origin of RIPA may save angiographic time, curtail contrast medium, and reduce radiation exposure.

Development of a method for reconstructing three-dimensional data from axial, sagittal, and coronal MR images.

Magnetic resonance (MR) imaging is useful for the diagnosis of brain atrophy and intracranial abnormalities. We have developed a method of automated volumetry to evaluate the degree of brain atrophy for the diagnosis of dementia. Whole-brain MR images with thin slices without gaps are required for segmentation and volumetry. However, obtaining such images requires that the patient remain at rest for a prolonged period, thereby reducing the throughput of MR imaging examinations. Therefore, a method is needed for the reconstruction of isotropic three-dimensional (3D) data using routine axial, sagittal, and coronal MR images with 30% gaps and measurement of brain volume. The method of reconstructing 3D data consists of four processes: 1) segmentation of the brain region on axial, sagittal, and coronal MR images using the region-growing technique; 2) setting data to a 3D domain; 3) registration by manual operation; and 4) interpolation between the data based on linear interpolation. In clinical MR images, the differences between this method and the conventional technique were less than 10%. These results demonstrate that this technique is able to construct 3D data from axial, sagittal, and coronal MR images.

[Visualization of the lower cranial nerves by 3D-FIESTA].

MR cisternography has been introduced for use in neuroradiology. This method is capable of visualizing tiny structures such as blood vessels and cranial nerves in the cerebrospinal fluid (CSF) space because of its superior contrast resolution. The cranial nerves and small vessels are shown as structures of low intensity surrounded by marked hyperintensity of the CSF. In the present study, we evaluated visualization of the lower cranial nerves (glossopharyngeal, vagus, and accessory) by the three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA) sequence and multiplanar reformation (MPR) technique. The subjects were 8 men and 3 women, ranging in age from 21 to 76 years (average, 54 years). We examined the visualization of a total of 66 nerves in 11 subjects by 3D-FIESTA. The results were classified into four categories ranging from good visualization to non-visualization. In all cases, all glossopharyngeal and vagus nerves were identified to some extent, while accessory nerves were visualized either partially or entirely in only 16 cases. The total visualization rate was about 91%. In conclusion, 3D-FIESTA may be a useful method for visualization of the lower cranial nerves.
