Studying the correlation between the results of the Common Achievement Test (basic objective structured clinical examination [OSCE] and computer-based testing [CBT]) and the results of advanced OSCE in the same examinees is necessary to improve clinical clerkships and to establish the role of each examination.
1) Ninety-seven students took the Common Achievement Test CBT and the basic OSCE in their fourth year and took the advanced OSCE in their sixth year. The Common Achievement Test basic OSCE were composed of interview, chest, abdomen, neurology, and head and neck stations, and the CBT included blocks 1-4 and 5-6. The advanced OSCE had 3 scenarios in the chest station, 2 in the abdomen station, and 4 in the neurology station. Each scenario had 3 items. We also examined the pass analysis on the basis of these 3 items in the advanced OSCE.
2) The results of the Common Achievement Test basic OSCE interview did not correlate significantly with the results of the interview station of the advanced OSCE. The results of physical examinations in the Common Achievement Test basic OSCE, excluding the chest, did not correlate significantly with the results of the physical examination stations of the advanced OSCE.
3) In the advanced OSCE, an adequate medical interview is necessary for the physical examination. An adequate physical examination is also necessary for answering the written tests (e.g., differential diagnosis). 4) Students should have sufficient basic knowledge and motivation for successfully performing clinical clerkships, because the correlations among the results of the advanced OSCE interview, the OSCE total score, the Common Achievement Test basic OSCE and CBT score were extremely strong.
5) The advanced OSCE, the Common Achievement Test basic OSCE, and CBT have distinct characteristics and roles.

Recently, LGBT has become a popular topic, people of various gender expressions appeared on TV. Gender diversity is widely known in Japan. On the other hand, a transwoman who has diagnosed with gender identity disorder was prohibited from using women’s restrooms and locker rooms. The incomprehensible prejudice against gender dysphoria remains persistent. Since people with various gender expressions come to the hospital for consultation, medical professionals are not allowed to be biased against various gender expressions. In this article, a strategy for resolving prejudice against people with gender dysphoria will be proposed.

OBJECTIVE: Medication adherence is important in the treatment of schizophrenia, and critical periods during treatment may be associated with relapse. However, the relationship between adherence and duration of outpatient treatment (DOT) remains unclear. The authors aimed to clarify the relationship between adherence and DOT at a psychiatric hospital in Japan. METHODS: For outpatients with schizophrenia who regularly visit Shin-Abuyama hospital, the authors conducted a single questionnaire survey (five questions covering gender, age, DOT, medication shortages, and residual medication) over one month period. Participants were divided into two groups whether DOT were from more than one year to within five years or not. Mantel-Haenszel analysis and logistic regression analysis were performed on the data regarding the medication adherence. RESULTS: Effective answers were received for 328 patients. The residual medication rate was significantly higher among those receiving outpatient treatment from more than one year to within five years than five years than those receiving outpatient treatment for more than five years or less than one year (p=0.016). CONCLUSION: This survey suggests that there are critical periods during which patients are most prone to poor adherence. Because poor adherence increases the risk of relapse, specific measures must be taken to improve adherence during these periods.

OBJECTIVE: Recent molecular and genetic investigations have suggested that the current nosology for major psychiatric disorders, based on the "two-entities-principal" is not accurate with respect to clinical observations; patient groups that do not fit to the current operative diagnostic boundaries are readily identified. We aimed to perform an investigation of the signal transducer and activator of transcription 6 (STAT6) gene (located on 12q13), which has an important role in the apoptotic cascade, with patients suffering from periodic psychosis. METHODS: Genetic association study has been employed for the current work. Investigated six tag-SNPs were chosen from Hapmap database. RESULTS: Among six tag-SNPs, one marker (rs10783813), located in the STAT6 gene, showed modest association (p<0.05), although no marker or haplotype block showed association after Bonferroni's correction. CONCLUSION: Future studies will reveal the etiological role of STAT6, and of other genes of the apoptotic cascade, in major psychiatric disorders.

OBJECTIVE: The anti-epileptogenic drug levetiracetam has anticonvulsant and anti-epileptogenesis effects. Synergy between cell death and inflammation can lead to increased levels of apoptosis inhibitory factors and brain-derived neurotrophic factor, aberrant neurogenesis and extended axon sprouting. Once hyperexcitation of the neural network occurs, spontaneous seizures or epileptogenesis develops. This study investigated whether the anti-epileptogenic effect of levetiracetam is due to its alternate apoptotic activity. METHODS: Adult male Noda epileptic rats were treated with levetiracetam or vehicle control for two weeks. mRNA quantification of Bax, Bcl-2 and GAPDH expression were performed from prefrontal cortex and hippocampus tissue samples. RESULTS: The levetiracetam-treated group showed a significant increase of Bax/Bcl-2 mRNA expression ratio in the prefrontal cortex than the control group, but no change in the Bax/Bcl-2 mRNA expression ratio in hippocampus. CONCLUSION: Idiopathic generalized epilepsy including childhood absence epilepsy develop at childhood and recover spontaneously during adolescence. The aberrant neural excitable network is pruned by a neural-maturing action. This study suggests the mechanism of acquired anti-epileptogenesis by levetiracetam treatment may be similar to spontaneous recovery of idiopathic generalized epilepsy during adolescence.

  We examined how difficult it would be for the elderly living in mountainous areas to go to the nearest hospital using a Voronoi tessellation representing the mathematical concept of neighborhood. We defined the index of the nursing-care capacity for the elderly as the ratio of the number of caregivers to the number of the elderly receiving nursing-care.
  The mean age of those who drive to the hospital by themselves worked out at 70±9.8 years. Meanwhile, that of those who go to the hospital by bus or taken to hospital in a car driven by a family member came to 80±7.0years. The latter was significantly older than the former.
  The areas of the Voronoi tessellation generated by patients' places of residence were divided into three groups according to the size. The plots of these three groups of the the places of residence on the map had a three-layer and doughnut-like structure, i. e., inner-, middle-, and outer-layer.
  The index of the nursing-care capacity in 2008 was less than 1.0 for the patients under 80 years of age. This means that when those who were at the age of 50 in 2008 become old and need nursing-care, access to the hospital will become harder to them than at present. For those who are over 80 years of age and live in the outer layer that is far away from arterial road, it will be almost impossible.
  These findings suggest that outpatient care with transportation assistance by a family member at present should be reconsidered because of the future lack of care personnel. It would also be necessary to consider the welfare of older people from the geographical point of view in order to manage the problems concerning the various physical and sociological difficulties of the elderly.

OBJECTIVE: The prevalence of attention deficit/hyperactivity disorder (ADHD) in school-age children is 7.2%, and ADHD is divided into clinical subtypes. METHODS: The current study explored whether specific cognitive profiles as assessed using the Wechsler Intelligence Scale for Children (WISC)-IV could be obtained for each clinical ADHD subtype (ADHD-Inattentive type and ADHD-Combined type) and investigated the correlation between WISC scores and parental age at their children’s birth or birthweight. The enrolled sample comprised 12 ADHD-I and 15 ADHD-C subjects. RESULTS: An impaired Processing Speed Index was found in ADHD-I. The age of the father at the child’s birth and birthweight positively correlated with the full scale intelligence quotient (FSIQ) score in the WISC assessment. CONCLUSION: Inattentiveness within the behaviors of the children with ADHD-I is partly due to the impaired processing speed, therefore effective support for ADHD will be conducted if educator decreases their speaking speed. Since biological basis of ADHD is still largely unknown, future studies using both psychological and biological methods will reveal the etiology of ADHD. These scientific assessments will provide information for more effective approaches in the care of children with ADHD.

OBJECTIVE: Electroconvulsive therapy (ECT) is a reasonable option for intractable depression or schizophrenia, but a mechanism of action has not been established. One credible hypothesis is related to neural plasticity. Three genes (Oct4, Sox2, c-Myc) involved in the induction of induced pluripotent stem (iPS) cells are Wnt-target genes, which constitute a key gene group involved in neural plasticity through the TCF family. Klf4 is the other gene among Yamanaka's four transcription factors, and increases in its expression are induced by stimulation of the canonical Wnt pathway. METHODS: We compared the peripheral blood gene expression of the four iPS genes (Oct4, Sox2, c-Myc, and Klf4) before and after modified ECT (specifically ECT with general anesthesia) of patients with intractable depression (n=6) or schizophrenia (n=6). Using Thymatron ten times the total bilateral electrical stimulation was evoked. RESULTS: Both assessments of the symptoms demonstrated significant improvement after mECT stimulation. Expression of all four genes was confirmed to increase after initial stimulation. The gene expression levels after treatment were significantly different from the initial gene expression in all twelve cases at the following treatment stages: at the 3rd mECT for Oct4; at the 6th and 10th mECT for Sox2; and at the 3rd, 6th and 10th mECT for c-Myc. CONCLUSION: These significant differences were not present after correction for multiple testing; however, our data have the potential to explain the molecular mechanisms of mECT from a unique perspective. Further studie should be conducted to clarify the pathophysiological involvement of iPS-inducing genes in ECT.

We investigated the possible association between genetic polymorphisms in the dopamine receptor and serotonin transporter genes and the responses of schizophrenic patients treated with either risperidone or perospirone. The subjects comprised 27 patients with schizophrenia who were clinically evaluated both before and after treatment. The genotyping of the polymorphisms of the dopamine D2 receptor gene (DRD2) (rs1801028 and rs6277), the dopamine D4 receptor gene (DRD4) (120-bp tandem repeats and rs1800955), and serotonin transporter gene (5HTT)(variable number of tandem repeats; VNTR) were performed using the real-time polymerase chain reaction and sequencing. In DRD2 and 5HTT-VNTR, there were no significant correlations between clinical response and polymorphism in the case of risperidone, and for perospirone treatment it was impossible to analyze the clinical evaluation due to the absence of genotype information. On the other hand, in DRD4 there were significant correlations in the two-factor interaction effect on the Positive and Negative Syndrome Scale (PANSS) between the two drugs [120-bp tandem repeat, p=0.003; rs1800955, p=0.043]. Although the small sample represents a serious limitation, these results suggest that variants in DRD4 are a predictor of whether treatment will be more effective with risperidone or with perospirone in individual patients.

OBJECTIVE: Accumulated evidence collected via functional near-infrared spectroscopy (fNIRS) has been reported with regard to mental disorders. A previous finding revealed that emotional words evoke left frontal cortex activity in patients with depression. The primary aim of the current study was to replicate this finding using an independent dataset and evaluate the brain region associated with the severity of depression using an emotional Stroop task. METHODS: Oxygenized and deoxygenized hemoglobin recording in the brain by fNIRS on 14 MDD patients and 20 normal controls. RESULTS: Hyperactivated oxygenized hemoglobin was observed in the left frontal cortex on exposure to unfavorable stimuli, but no significant difference was found among patients with depression compared with healthy controls on exposure to favorable stimuli. This result is consistent with previous findings. Moreover, an evoked wave associated with the left upper frontal cortex on favorable stimuli was inversely correlated with the severity of depression. CONCLUSION: Our current work using fNIRS provides a potential clue regarding the location of depression symptom severity in the left upper frontal cortex. Future studies should verify our findings and expand them into a precise etiology of depression.
