Cotard's syndrome is a rare clinical condition characterized by the presence of nihilistic delusions, delusions of immortality, depressive mood, and anxiety. Longitudinal changes in regional cerebral blood flow (rCBF) obtained under different conditions with and without Cotard's syndrome have rarely been reported in the literature. We report a case of a patient with Cotard's syndrome in whom longitudinal rCBF was assessed using single-photon emission computed tomography (SPECT).

Recoverin is a neuron-specific calcium-binding protein that is mainly located in the retina and pineal gland. Few reports have described patients with anti-recoverin antibody-positive encephalitis, and no cases of psychosis associated with this encephalitis have been reported. We report a patient with anti-recoverin antibody-positive encephalitis with Cotard and Capgras delusions who was successfully treated with electroconvulsive therapy (ECT).

Antidepressant-induced jitteriness/anxiety syndrome is characterized as anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, and (hypo)mania, which appear immediately after initiation or increased dosage of an antidepressant. This report describes a case of the jitteriness/anxiety syndrome caused by the coadministration of celecoxib with escitalopram and trazodone in a patient with depression and spondylolisthesis. The depression of a patient, a woman in her 60 s, had been in remission at least for 5 years under treatment using escitalopram and trazodone.

Background: Neuroleptic malignant syndrome (NMS), a rare but potentially life-threatening adverse reaction to treatment with antipsychotic drugs, is characterized by hyperthermia, muscle rigidity, impaired consciousness, and autonomic disturbances. Some reports have described rapidly progressing cases of NMS resulting in death within several days. This report describes a clinical course of fatal and fulminant NMS in a patient with schizoaffective disorder.

Background: Serotonin syndrome is characterized by mental status changes, autonomic hyperactivity, and neuromuscular abnormalities. This syndrome results from various medications that engender serotonergic overactivity. Atomoxetine is a norepinephrine reuptake inhibitor used for the treatment of attention-deficit hyperactivity disorder (ADHD).

Background: The μ-opioid receptor (MOR) plays an important role in social bonding behaviors, while it is implicated in the pathophysiology of depression. It is shown that the A118G polymorphism (rs1799971) of the MOR gene (OPRM1) causes amino-acid exchange from Asn to Asp, and that this polymorphism is associated with altered mu-opioid receptor function. Meanwhile, sociotropy/autonomy and interpersonal sensitivity are personality vulnerabilities to depression characterized by distinctive interpersonal styles.

Introduction: Oxytocin receptor (OXTR) gene polymorphism reportedly moderates effects of negative environments during childhood on mental function and behavior such as depressive symptoms and externalizing problems. This study examined OXTR gene polymorphism effects on personality traits in healthy participants, considering interaction effects of polymorphism with affectionless control (AC) parenting which is one of the dysfunctional and pathogenic parenting styles.

Methods: For 496 Japanese volunteers, personality was evaluated using the Temperament and Character Inventory.

BACKGROUND Catatonia can occur in various neuropsychiatric disorders and is usually treated with benzodiazepines. So far, although 1 case of dementia with Lewy bodies (DLB) with catatonia has been reported, there have been no reports on patients with DLB whose initial symptom was a catatonia. Here, we present a patient who developed benzodiazepine-resistant catatonia and was subsequently diagnosed with DLB based on DLB biomarkers.

BACKGROUND A musical hallucination (MH) is a type of auditory hallucination, and is defined as hearing music, sounds, or songs in the absence of external auditory stimuli. There are several case reports of conventional doses of tri- or tetracyclic antidepressants inducing MHs, but no such report for selective serotonin reuptake inhibitors. Here we report a case of a patient with MHs induced by conventional doses of paroxetine.

Purpose: Attachment research shows that attachment experiences with parents in childhood influence the characterization of personality traits. Meanwhile, it is known that mu-opioid receptor function is involved in human attachment. Furthermore, a few studies suggest that the A118G polymorphism of the mu-opioid receptor gene () is associated with altered mu-opioid receptor function.

Purpose: It is suggested that increased methylation of the brain-derived neurotrophic factor (BDNF) gene is involved in the pathogenesis of depression, while sociotropy and autonomy are proposed as personality vulnerability factors in cognitive model of depression. We examined the interrelation between BDNF gene methylation and sociotropy or autonomy, with taking into account the previously reported deleterious effect of parental overprotection on sociotropy.

Materials And Methods: The participants consisted of 90 healthy Japanese volunteers.

Objective: The relationship between serum creatinine and calcium (Ca) was investigated in hematopoietic stem cell transplantation (HSCT) patients treated with foscarnet.

Materials And Methods: A retrospective study was performed to investigate the development of foscarnet-induced renal dysfunction in patients who received HSCT from April 2010 to November 2018 at the Kindai University Nara Hospital. A total of 80 patients were identified from the medical records, and 42 patients who met the inclusion criteria were enrolled in this study.

Objective: We aimed to clarify the drug interaction between tacrolimus and voriconazole and investigate the relationship between blood concentrations of tacrolimus and voriconazole in hematopoietic stem cell transplantation (HSCT) patients.

Materials And Methods: A retrospective study was conducted to investigate the relationship between blood concentration of tacrolimus and that of voriconazole at the Kindai University Nara Hospital. Patients who received HSCT and tacrolimus and were prescribed voriconazole for the prevention or treatment of aspergillosis from April 2010 to July 2018 were identified from the medical records.

Objective: We aimed to investigate the relationship between voriconazole (VRCZ) trough concentrations and hepatotoxicity and to evaluate whether the recommended trough concentration is adequate in our clinical setting.

Materials And Methods: A retrospective study was performed to investigate the relationship between serum VRCZ concentrations and the development of hepatotoxicity at the Kindai University Nara Hospital. Patients treated with VRCZ from March 2010 to January 2018 were identified from the medical records.

Background: Brain-derived neurotrophic factor (BDNF) is a neurotrophin that has an important function in neuroplasticity and neuronal development. It is suggested that increased methylation of the BDNF gene resulting in decreased BDNF activity is associated with depression. Meanwhile, neuroticism is a well-known risk factor for developing depression.

Aims: The diacylglycerol kinase η gene (DGKH) is one of the few replicated risk genes for bipolar disorder. Meanwhile, specific personality traits, especially openness to experience, have been suggested as premorbid personality traits of the disorder. The aim of the present study was to examine the relation of the DGKH genotype with broad dimensions of personality, to obtain further evidence for its implication in the etiology of bipolar disorder.

We investigated the evolution of transmembrane (TM) topology by detecting partial sequence repeats in TM protein sequences and analyzing them in detail. A total of 377 sequences that seem to have evolved by internal gene duplication events were found among 38,124 predicted TM protein sequences (except for single-spannings) from 87 prokaryotic genomes. Various types of internal duplication patterns were identified in these sequences.
