Secondary Mania after Cerebral Infarction in the Recovery Phase: Case Report.

Introduction: Although patients commonly experience psychological disorders such as depression following cerebrovascular events, mania is extremely rare. Here we present a patient who experienced secondary mania while being hospitalized in a convalescent rehabilitation ward following cerebral infarction.

Case: The patient was a 70-year-old man who was hospitalized at our hospital for convalescent rehabilitation after suffering mild right hemiplegia and higher brain dysfunction following cerebral infarction.

[A case of unresectable advanced pancreatic cancer treated by gemcitabine-based chemotherapy following cancer pain alleviation by low-dose matrix-type transdermal fentanyl].

Cancer pain often makes patient's performance status worsen and is one of the difficulties in anti-cancer therapy. We report a case of unresectable advanced pancreatic cancer with cancer pain, which was treated by matrix-type transdermal fentanyl following slow-releasing oxycodone, which caused severe constipation. Rotation to matrix-type transdermal fentanyl (Durotep MT 2.

Association study of the G72 gene with schizophrenia in a Japanese population: a multicenter study.

G72 is one of the most widely tested genes for association with schizophrenia. As G72 activates the D-amino acid oxidase (DAO), G72 is termed D-amino acid oxidase activator (DAOA). The aim of this study is to investigate the association between G72 and schizophrenia in a Japanese population, using the largest sample size to date (1774 patients with schizophrenia and 2092 healthy controls).

Impaired regional hemodynamic response in schizophrenia during multiple prefrontal activation tasks: a two-channel near-infrared spectroscopy study.

In schizophrenia, dysfunction of the prefrontal cortex (PFC), regarded as a core feature of the disease, has been investigated by different neuroimaging methods. Near infrared spectroscopy (NIRS), a novel neurophysiological method, is being increasingly used in the investigation of frontal dysfunction in schizophrenia. However, NIRS measurements during multiple frontal activation tasks have been rarely reported.

Frontal activity during the digit symbol substitution test determined by multichannel near-infrared spectroscopy.

Background: The digit symbol substitution test (DSST) is a clinically useful and widely accepted tool for the detection of various psychiatric disorders. Investigating neural activity during the DSST is useful when considering the relationship between the poor performance on the DSST and neurocognitive deficits. However, obtaining reliable functional imaging of the neural mechanisms associated with this test is challenging due to motion artifacts.

Discrepancy of performance among working memory-related tasks in autism spectrum disorders was caused by task characteristics, apart from working memory, which could interfere with task execution.

Working memory performance has been inconsistently reported in autism spectrum disorders (ASD). Several studies in ASD have found normal performance in digit span and poor performance in digit symbol task although these are closely related with working memory. It is assumed that poor performance in digit symbol could be explained by confirmatory behavior, which is induced due to the vague memory representation of number-symbol association.

Spatial working memory deficit correlates with disorganization symptoms and social functioning in schizophrenia.

Both spatial working memory deficit and disorganization symptoms have been considered significant components of schizophrenic impairment involved with the dorsolateral prefrontal cortex. The purpose of the present study was to investigate the relationships among spatial working memory, psychiatric symptoms including disorganization symptoms, and social functioning in schizophrenia. Fifty clinically stable patients with schizophrenia and 34 healthy controls participated in the study.

A stress-induced, superoxide-mediated caspase-1 activation pathway causes plasma IL-18 upregulation.

Psychological/physical stresses are known to cause relapses of autoimmune and inflammatory diseases. To reveal a mechanism by which noninflammatory stresses affect host defenses, responses to immobilization stress in mice were investigated, focusing on the role of a multifunctional cytokine, interleukin-18 (IL-18). In the adrenal cortex, the stress induced IL-18 precursor proteins (pro-IL-18) via adrenocorticotropic hormone (ACTH) and a superoxide-mediated caspase-1 activation pathway, resulting in conversion of pro-IL-18 to the mature form, which was released into plasma.
