Different psychopathological courses between chronic interictal psychosis and schizophrenia.

Objective: The clinical course of interictal psychosis (IIP) has not yet been investigated. We aimed to compared the psychopathology and time-relevant indices between chronic IIP (CIIP) and schizophrenia (SC) METHODS: In this comprehensive psychopathological study, patients with chronic psychosis with and without epilepsy (127 with CIIP and 187 with SC) were compared. Psychopathology was measured using the Brief Psychiatric Rating Scale (BPRS): total, negative symptoms (NSs), positive symptoms (PSs), and anxiety-depressive symptoms (ADSs).

Procalcitonin-Based Antibiotic Use for Neonatal Early-Onset Bacterial Infections: Pre- and Post-Intervention Clinical Study.

We previously reported the 95th percentile cutoff value of the serum procalcitonin (PCT) reference curve for diagnosing early-onset bacterial infection. We aimed to verify the effectivity of these novel diagnostic criteria by comparing antibiotic use and incidence of early-onset bacterial infection between pre- and post-introduction periods. We included newborns admitted to our neonatal intensive care unit who underwent blood tests within 72 h after birth between 2018 and 2022.

Psychoses after an antiepileptic drug administration: Frequency, timing, and duration.

Objectives: To clarify the pathophysiology of psychoses after the new administration of antiepileptic drugs (AED), we analyzed the annual incidence, timing of development, and duration of episodes.

Methods: Psychotic outcomes in the first 6-month period after an AED or non-AED administration in patients with focal epilepsy were exhaustively reviewed in eight Japanese neuropsychiatry institutions. In cases with psychotic episodes, the subtype of psychosis, timing of development, previous history of psychosis, and duration of the episode were evaluated.

Association of umbilical cord insulin-like growth factor 1 levels with severe retinopathy in extremely preterm infants.

Background: The association between umbilical cord blood insulin-like growth factor 1 (IGF-1) levels and retinopathy of prematurity (ROP) remains unclear. This study aimed to investigate whether umbilical cord blood IGF-1 levels can predict the development of severe ROP in extremely preterm infants.

Methods: This hospital-based retrospective cohort study included infants born at <37 weeks gestational age (GA) between 2019 and 2021 and then classified them into the two GA groups: extremely preterm, <28 weeks and preterm infants, 28-36 weeks.

Percentile-Based Reference Values of Umbilical Cord Blood Insulin-like Growth Factor 1 in Japanese Newborns.

We aimed to create percentile-based reference values of the umbilical cord blood insulin-like growth factor-1 (IGF-1) levels in Japanese newborns, as these values have not yet been established. A total of 259 newborns were classified into four gestational-age-at-birth (GA) groups: extremely preterm (<28 weeks); early preterm (28−33 weeks); late preterm (34−36 weeks); and term (≥37 weeks). They were further subclassified as small-for-gestational-age (SGA) or non-SGA.

Risk factors for early-phase clozapine discontinuation: A nested case-control study.

Objectives: Safe and efficient methods for introducing clozapine to patients with treatment-resistant schizophrenia (TRS) are needed. We investigated risk factors for clozapine discontinuation in the early phase of its introduction.

Methods: We conducted a nested case-control study at 14 psychiatric hospitals in Chiba, Japan.

Individual vulnerabilities to psychosis after antiepileptic drug administration.

Background: Psychosis often develops after the administration of antiepileptic drugs (AEDs) in patients with epilepsy. However, the individual vulnerability and clinical condition of such patients have been rarely scrutinised. We investigated the effect of individually consistent (trait-dependent) and inconsistent (state-dependent) characteristics.

Increased frequency of psychosis after second-generation antiepileptic drug administration in adults with focal epilepsy.

Objective: Many studies show psychoses after some antiepileptic drug (AED) administrations (post-AED administration psychoses [PAP]). It remains uncertain about psychogenetic potential of each AED and effects of clinical state factors on PAP. We examined the relations between AED-related factors (types, generations, dosages, and concomitant AED) and PAP.

Primary Aldosteronism With Type 2 Diabetes Mellitus Requires More Antihypertensive Drugs for Blood Pressure Control: A Retrospective Observational Study.

Background: Diabetes mellitus (DM) and primary aldosteronism (PA) have been reported to induce drug-resistant hypertension and atherosclerosis. It is likely that blood pressure (BP) control becomes far more difficult in PA patients with DM. However, precise clinical characteristics of PA with type 2 DM especially in the aspect of BP control are not clear.

TSH and PRL, side-effect markers in aripiprazole treatment: adjunctive aripiprazole-induced thyrotropin oversuppression in a young man with schizophrenia.

A 26-year-old Japanese man was admitted to our unit with exacerbated paranoid schizophrenia. Prior to his admission, daily administration of olanzapine had been sufficient to maintain a partial remission of his schizophrenia, but due to an exacerbation of his delusions, he had then also been prescribed aripiprazole, which had been followed by no improvement in symptoms and a gradual further exacerbation of auditory delusions. Physical examinations, brain MRI and neurophysiological assessment were unremarkable.

[Deceased Schizophrenic Patients--Focus on QT Prolongation].

We retrospectively evaluated factors affecting the lifespan of schizophrenic patients, who are known to have a shorter life expectancy than healthy people, focusing on the relationship with QT prolongation associated with antipsychotics. In a total of 406 patients who died at Asai Hospital the mean age at death was compared between schizophrenic patients and nonpsychiatric patients. In deceased schizophrenic patients, drug-related factors, hematology results, and electrocardiographic findings for 3 years before death were compared with those for the same period in age-matched surviving schizophrenic patients.

Dissociative experiences in epilepsy: effects of epilepsy-related factors on pathological dissociation.

Psychogenic nonepileptic seizures (PNESs) in patients with epilepsy can be categorized as dissociative disorders. The prevalence of PNESs in patients with epilepsy appears to be much higher than that of dissociative experiences in nonclinical subjects. In order to clarify as to whether epilepsy-related factors were associated with pathological dissociation, we conducted a controlled study with 225 patients with epilepsy and 334 nonclinically matched individuals.

Do antipsychotic drugs increase seizure frequency in epilepsy patients?

To investigate whether addition of antipsychotic drugs (APD) would increase seizure frequency in epilepsy patients who were already treated with anti-epileptic drugs (AED), we compared a one-year seizure control outcome in 150 epilepsy patients with APD treatment for psychiatric conditions and 309 epilepsy patients without APD treatment matched for ages at epilepsy onset and the baseline evaluation and types of epilepsy. The seizure frequency was recorded at the baseline (immediately before the start of APD) and after the 1st, 3rd, 6th and 12th months. The seizure outcome at each of the four follow-up points was compared with the baseline.

Effects of antipsychotic drugs on the duration of interictal psychotic episodes in patients with epilepsy.

Treatment protocols for interictal psychosis (IIP) of patients with epilepsy have not yet been established. We aimed to clarify the effects of antipsychotic drugs (APDs) on duration of IIP episodes. We studied 393 IIP episodes in 200 patients with epilepsy in accordance with our empirical treatment protocol.

Psychiatric comorbidity in adult patients with idiopathic generalized epilepsy.

We reviewed the medical records of 157 adult (18 years) patients with firmly diagnosed idiopathic generalized epilepsy (IGE) to investigate the extent and the type of psychiatric comorbidity and its relationship to various IGE syndromes and other epilepsy-related neurobiological factors. Forty-one patients (26.1%, 14 men and 27 women, median age: 34.
