OBJECTIVES: This study investigated whether long-acting injectable (LAI) paliperidone is different from its oral form in terms of the effect on cognitive function in schizophrenia spectrum and other psychotic disorders. METHODS: We reviewed the medical records of patients in Seoul National University Bundang Hospital who were diagnosed as having schizophrenia and/or other psychotic disorders based on DSM-5 from 2016 to 2017. Seven patients were treated with oral paliperidone and 11 were treated with paliperidone palmitate. All patients underwent clinical and neuropsychological assessment, including the Korean version of the MATRICS Consensus Cognitive Battery (MCCB) at their first visit or within one month of their initial treatment. MCCB was repeated within three to 12 months after the initial assessment. RESULTS: There was no significant difference between the two groups in most cognitive domains including speed of processing, attention and vigilance, working memory, verbal learning, visual learning and reasoning and problem solving domain. However, patients treated with paliperidone palmitate showed better improvement in social cognition domain than those taking oral paliperidone. The standardized values of social cognition domain scores had significantly improved over time in patients under paliperidone palmitate, demonstrating a significant time-by-group interaction. CONCLUSION: Our results show that long-acting injectable paliperidone could be helpful in some aspects of improving cognitive function in schizophrenia spectrum and other psychotic disorders. Further studies with other antipsychotics are necessary to generalize the results.

Objective: The clozapine/N-desmethylclozapine (NDMC) ratio is proposed to be used as a predictor of cognitive performance in clozapine-treated patients, as its principal metabolite, NDMC, has an opposite action with clozapine on the cholinergic system. The aim of this study is to determine whether clozapine has influence on cognitive performance in accordance with changes in the clozapine/NDMC in patients with schizophrenia. Methods: The data of fifteen patients with schizophrenia, who had initial and follow-up assessments after starting clozapine treatment, were retrospectively collected. The assessments included clinical scale, cognitive battery, and pharmacological data including plasma concentrations of clozapine and NDMC. The data were analyzed with Pearson correlation and stepwise multiple regression analyses. Results: ΔAttention/vigilance, Δsocial cognition, and Δcomposite score had a significant correlation with Δclozapine/NDMC ratio, while ΔWorking memory had correlation with Δclozapine concentration and ΔNDMC concentration, and Δsocial cognition had association with Δclozapine concentration. Multiple regression analysis showed that Δattention/vigilance had negative association with Δclozapine/NDMC ratio, Δworking memory had negative relation with Δclozapine concentration, and that Δsocial cognition had negative association with Δclozapine concentration. Conclusion This finding implicates that lowering the clozapine/NDMC ratio could enhance cognition in patients with schizophrenia treated with clozapine.

Schizophrenia is a complex psychiatric disorder characterized by hallucinations, delusions, and cognitive deficits, often leading to functional decline. Pharmacotherapy has long played a central role in schizophrenia management with our evolving understanding shaping the treatment.Current Concepts: Antipsychotic agents are the mainstay of the pharmacological treatment of schizophrenia. Although second-generation antipsychotics (atypical) reduce extrapyramidal side effects, they give rise to metabolic concerns. Personalized treatment, guided by the response and side effects of the patient, determines suitable medications and dosages. Long-acting injectable antipsychotics have enhanced medication adherence, and the consideration of clozapine is warranted for treatment-resistant cases. In addition, potential combination therapies with other psychotropic medications could be explored to address specific symptoms or comorbidities.Discussion and Conclusion: Antipsychotics are pivotal in acute intervention and schizophrenia treatment maintenance. Individualized plans, accounting for drug response, side effects, and adherence, are essential when selecting specific antipsychotic agents. Long-acting injectables and clozapine with combination therapies for treatment resistance offer effective and tolerable management. Ongoing studies and novel antipsychotic development hold promise for improving schizophrenia treatment and patient life quality.

OBJECTIVES: This study investigated the prescribing patterns of atypical antipsychotics for the various psychiatric disorders in the psychiatric ward of a University hospital. METHODS: We reviewed the medical records of patients who were discharged from an open psychiatric ward from May, 2003 through April, 2014. The association between psychiatric disorders and prescription pattern of atypical antipsychotics was analyzed. RESULTS: The study included 3091 patients' prescription of psychiatric medication. 60% of prescription included antipsychotics; quetiapine was the most frequently prescribed antipsychotics, but the average dosage was the lowest among all the atypical antipsychotics. According to the diagnoses, prescription rates and dosage of antipsychotics were different. Prescription rates of antipsychotics were the lowest in patients with anxiety disorders, and the mean dosage were the lowest in those with delirium, dementia, and amnestic and other cognitive disorders. CONCLUSION: This observational study shows prescription patterns of atypical antipsychotics for the treatment of psychiatric disorders in a University hospital; atypical antipsychotics were widely used for the treatment of the various disorders, and there were differences in prescription patterns for each disorders. The results of this study may be used to identify the proper atypical antipsychotics effective on certain psychiatric disorders and to propose expanding the indications of each atypical antipsychotics in the future.

A large proportion of patients with schizophrenia show a poor response to first-line antipsychotic drugs, which is termed treatment-resistant schizophrenia. Previous studies found that a different neurobiology might underlie treatment-resistant schizophrenia, which necessitates the development of different therapeutic approaches for treating treatment-resistant schizophrenia. This study reviewed previous studies on the pathophysiology of treatment-resistant schizophrenia and the pharmacological intervention, and forthcoming investigations of treatment-resistant schizophrenia are suggested.

A traumatic diaphragmatic hernia is a rare combined problem involving injuries to the thorax and abdomen that may not be diagnosed at the time of injury. Surgical management is mandatory when the patient displays any signs of bowel strangulation due to the herniation because a herniated bowel has a very high risk of necrosis or perforation. Four patients were diagnosed with delayed traumatic diaphragmatic hernia 14 to 96 months after injury. In two patients, the diaphragmatic injury was missed at the time of injury. Reduction and diaphragm repair surgery were performed. One diaphragm was repaired with artificial mesh. Traumatic diaphragmatic injury is caused by a blunt or penetrating injury to the abdomen or thorax. After migration of the intra-abdominal contents into the chest, a narrow herniation defect can disturb the bowel circulation and passage of bowel contents. Early detection and reduction, and repair surgery are mandatory for patients with a delayed presentation of complicated traumatic diaphragmatic hernia. Any patient with injury around the thorax or upper abdomen should be examined carefully considering the possibility of diaphragmatic hernia. Even if diaphragmatic injuries are not found in the initial evaluation, a radiology examination in a short period of time can correct the missed diagnosis of traumatic diaphragmatic hernia.

A 61-year-old man presented with abdominal distension without any symptoms. On colonoscopy and computed tomography findings, it was clinically diagnosed as peritoneal metastasis of sigmoid colon cancer, and diagnostic laparoscopy was performed. Only the peritoneum was partially resected, and the pathology was signet ring cell carcinoma with predominantly local mucinous carcinoma component. However, the patient complained of persistent symptoms and, despite the progress of chemotherapy, the peritoneal dissemination worsened, and additional cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) was performed. Mixed adenoneuroendocrine carcinomas (MANECs) were reported in the appendix with perforated visceral peritoneum. After additional chemotherapy, the patient was discharged. Patients with advanced MANEC with peritoneal spreading may benefit from aggressive treatment by cytoreduction surgery with HIPEC, followed by intravenous chemotherapy.

Objective: More attempts have been made recently to improve psychosocial functioning and quality of life in patients with schizophrenia, due to their crucial role in long-term outcomes. Previous studies on the effects of clozapine on psychosocial functioning have been limited in terms of generalizability and application to clinical practice. This study examined the relationship of clozapine use with psychosocial functioning and quality of life in patients with schizophrenia in a real-world setting. Methods: Data were obtained from a survey targeting community-dwelling patients with schizophrenia. The Behavior and Symptom Identification Scale (BASIS) and Satisfaction with Life Scale (SWLS) were administered to evaluate psychosocial functioning and quality of life, and patients were classified into Clozapine and Non-clozapine groups. Group differences were assessed using ANCOVA, with additional sensitivity analyses for participants on atypical antipsychotic medications only. Results: Of 292 patients, the Clozapine group (n=34) had significantly better psychosocial functioning and quality of life than the Nonclozapine group (n=258), as demonstrated by their low BASIS score (F=4.651, df=1, 290, p=0.032) and high SWLS score (F=14.637, df=1, 290, p<0.001). Similar findings for psychosocial outcomes were observed in the analyses of the atypical antipsychotic subgroup (n=195). Conclusion For optimal recovery in schizophrenia, restoration of impaired social functioning and enhanced satisfaction with life are essential. In this study, clozapine use was related to high levels of psychosocial functioning and quality of life in real-world settings. Further research on the causal relationship between clozapine use and psychosocial functioning is needed.

OBJECTIVE: The aims of this study were to quantify the costs of treatment in patients with schizophrenia and to compare the cost according to the relapse status. METHODS: A total of 330 patients were consecutively enrolled from 11 hospitals in Korea. Differences in direct medical costs by relapse status in the 6 months were examined. RESULTS: The medical cost in patients with relapse was about seven times higher than the cost in patients without relapse. The cost for hospitalization largely accounted for the cost in patients who relapsed. The most common reason for the hospitalization in patients with relapse was poor drug compliance. CONCLUSION: Relapse in patients with schizophrenia significantly increases medical costs in Korea.

OBJECTIVE: The aim of this study was to observe the safety and efficacy of ziprasidone in the usual care setting in patients with schizophrenia or acute manic or mixed episodes associated with bipolar disorder. METHODS: A total of 3,391 patients who were treated with ziprasidone were enrolled from 108 centers in Korea. Differences in the clinical global impression of severity and clinical global impression of improvement (CGI-I) were measured after 8+/-1 weeks administration of ziprasidone. Adverse events were observed in all subjects who were administered ziprasidone at least once. In 330 patients, the change of weight was evaluated. RESULTS: Ziprasidone was effective for most of schizophrenia and acute manic or mixed episodes associated with bipolar disorder patients. CGI-I score was improved in 84.8% of PP subjects. Of the subjects who did not complete the study, sixty-four (1.9%) subjects discontinued treatment due to adverse events. The most common adverse events were akathisia, somnolence, extrapyramidal symptoms and insomnia. In total, 6 serious adverse events were reported in 2 subjects, including psychotic disorder and suicidal attempt. Mean 0.9 kg of weight loss was observed. CONCLUSION: Ziprasidone was effective, safe and generally well tolerated for schizophrenia or acute manic or mixed episodes associated with bipolar disorder patients in Korea.
