Bipolar patients often experience subjective symptoms even if they do not have active psychotic symptoms in their euthymic state. Most studies about subjective symptoms are conducted in schizophrenia, and there are few studies involving bipolar patients. We examined the nature of the subjective symptoms of bipolar patients in their euthymic state, and we also compared it to that of schizophrenia and normal control. Thirty bipolar patients, 25 patients with schizophrenia, and 21 normal control subjects were included. Subjective symptoms were assessed using the Korean version of the Frankfurter Beschwerde Fragebogen (K-FBF) and the Symptom Check List 90-R (SCL90-R). Euthymic state was confirmed by assessing objective psychopathology with the Positive and Negative Syndrome scale of Schizophrenia (PANSS), the Young Mania Rating Scale (YMRS), and the Montgomery Asberg Depression Rating Scale (MADRS). K-FBF score was significantly higher in bipolar patients than in normal controls, but similar to that in schizophrenia patients (F=5.86, p=0.004, R(2)=2033.6). In contrast, SCL90-R scores did not differ significantly among the three groups. Euthymic bipolar patients experience subjective symptoms that are more confined to cognitive domain. This finding supports the hypothesis that subtle cognitive impairments persists in euthymic bipolar patients.

Serotonin syndrome is an unexpected fatal adverse event related to serotonergic medication. This case report is the first report describing the possible treatment effect of famotidine on serotonin syndrome. Furthermore, this is the first case report of serotonin syndrome induced by meperidine alone in a patient with no previous history suggesting a susceptibility to serotonin syndrome. A 70-year-old male with no recent history of serotonergic drug use presented with severe serotonin syndrome following ureteroscopy, possibly due to postoperative meperidine administration. The patient's symptoms included hypertension, tachycardia, tachypnea, hyperthermia, myoclonus, diaphoresis, retching, nausea, agitation, and semicoma mentality with no pupillary light reflex. Symptoms began to subside immediately after the administration of intravenous famotidine for prevention of aspiration pneumonia, with mental and neurological symptoms showing improvement initially, followed by autonomic symptoms. This case report suggests that the histamine type 2 receptor antagonist famotidine may be an effective emergency treatment for serotonin syndrome.

OBJECTIVES: Neurocognitive dysfunction may provide a marker of underlying neuropathology and disease vulnerability in bipolar disorder. The aim of this study was to identify the differences and the profiles of cognitive deficits in euthymic bipolar patients and first-degree relatives of bipolar probands. METHODS: Twenty four unaffected first-degree relatives of probands with bipolar I disorder (BD) were included in the study as an equal number of remitted BD patients and healthy controls who were matched on age, sex, years of education, and general intelligence. Cognitive assessments were performed using the Digit Span Test, Continuous Performance Test, Rey Auditory & verbal Learning Test, Complex Figure Test, Verbal Fluency Test, Wisconsin Card Sorting Test, and Finger Tapping Test. The effect of subsyndromal symptomatology was controlled. RESULTS: Patients showed significantly worse performance than healthy control subjects in several measures of attention, working memory, verbal learning and memory, visual memory (delayed recall), and verbal fluency (category). Relatives showed significant impairment in working memory. No differences were observed in sustained attention, cognitive flexibility, and psychomotor performance. CONCLUSION: Findings of our study suggest that the deficit in working memory could be a potential endophenotypic marker of genetic vulnerability to BD. Verbal learning and memory impair ment appears to be more related to the fully developed BD.

Objective: Two years after the 2017 Pohang earthquake, some people sought follow-up mental health support. The demographic and clinical characteristics of this unique group of people were investigated to identify some insights on the predisposing factors of the longterm need for psychiatric help after a severe earthquake disaster. Methods: De-identified data from those seeking mental health support 2 years after the 2017 Pohang earthquake were used. The descriptive statistics of demographic and clinical characteristics of the study group was identified and paired with general population data obtained from open and public governmental websites. Sex, age distribution, destruction of house, and psychiatric disorder were compared between the follow-up sample and general population. Results: The proportion of women in the group seeking support was two times higher than that in the general population, and people ages between 50 and 70 years commonly sought support. The severity of home destruction was higher among people who sought and needed follow-up mental health support programs than in the general population. There was a higher proportion of people with psychiatric disorders in the group seeking support than in the general population. Conclusion The need for long-term mental health support 2 years after an earthquake was higher in women than in men and those aged between 50 and 70 years, and those with a previous psychiatric history and with a higher severity of home destruction, which lead to necessitating leaving the home. Future earthquake response should include screening and psychiatric treatment referral and residential support in vulnerable people.

OBJECTIVES: The aim of this study was to compare the coping strategies among healthy controls, psychotic and neurotic patients and to evaluate the predictors of suicidal ideation. METHODS: The study population consisted of 115 outpatients in Ulsan University Hospital and 160 healthy controls. They filled out self-report questionnaires including demographics and validated psychiatric scales for depression, perceived stress, coping strategies, and suicide ideation. An analysis of the covariance was used to compare the clinical data among the groups. Stepwise multiple regression analysis was performed to estimate the effects of coping strategies and depression on the risk for suicidal ideation. RESULTS: Compared to the controls, the psychosis group used less active coping, and the neurosis group used more self-blame coping strategies. In healthy controls, suicidal ideation was predicted by depression, female gender, and using more self-blame coping. Although planning in psychosis was a protective factor, acceptance and self-blame in psychosis and behavioral disengagement in neurosis was a risk factor for suicidal ideation. CONCLUSION: Patients with psychotic and neurotic disorders use different coping strategies to deal with their distress and some of those are risk factors for suicidal ideation. Therefore, improving coping skills will be helpful for preventing suicide by alleviating the levels of stress and providing more effective emotion regulation.

Charles Bonnet syndrome (CBS) can develop after trans-sphenoidal adenomectomy (TSA); however, the neural mechanisms remain unknown. Sensory deprivation and releasing phenomenon are both hypothetical explanations for this condition; however, there is no definite evidence that strongly supports either supposition. We report the first case of CBS after TSA without optic nerve atrophy. Postoperatively, the patient's vision seemed to be relatively well preserved, apart from the left-side hemianopsia in the right eye. Distinctive visual hallucinations only appeared when his eyes were closed, and these responded to quetiapine in a dose-dependent manner. Dose dependent change in colors and formation of hallucination was reported. Two weeks after quetiapine initiation, the patient's CBS was completely resolved. This unique case suggests that blocking sensory input from the periphery is more critical than neural damage of the bottom-up connection to the visual association cortex. In addition, quetiapine should be considered as a specific treatment for CBS.

Serotonin syndrome is an unexpected adverse reaction of serotonergic medication. Some drugs used by anesthesiologists may cause serotonin syndrome. Serotonin syndrome is known to be related to 5-hydroxytryptamine 1A and 5-hydroxytryptamine 2A agonism. However, recent research has revealed evidence that 5-hydroxytryptamine 3 (5-HT3) antagonism can also play a role in serotonin syndrome. Among the 5-HT3 antagonists, palonosetron is the most highly specific. In this study, we present the first case of fentanyl- and meperidine-induced serotonin syndrome precipitated by palonosetron in general anesthesia.

OBJECTIVE: Posttraumatic embitterment disorder (PTED) is characterized by states of “embitterment”, characteristically similar to “Hwa-byung”, which is a Korean culture-bound syndrome. The present study aimed to assess diagnostic relationships between PTED and Hwa-byung. METHODS: A total of 290 participants completed our survey. PTED and Hwa-byung were diagnosed using a diagnostic interview and scale. Scales for depression, suicide ideation, and anger were used for evaluation. Fisher's exact tests and Mann-Whitney U tests were performed to evaluate diagnostic overlap between PTED and Hwa-byung, and associations of scale scores for depression, suicide ideation, and anger between the PTED, Hwa-byung, and non-diagnosed groups. Associations of these scales between the depressive and non-depressive groups, and suicidal and non-suicidal groups were also evaluated. RESULTS: Among the participants, 1.7% of the sample fit the diagnostic criteria for PTED and 2.1% fit the criteria for Hwa-byung. No individual fit the criteria for both. Anger scores were significantly higher in the Hwa-byung group than in the non-diagnostic group. There were not any significant differences in anger scores between the PTED and non-diagnostic groups. Depression scores were significantly higher in the PTED than in the non-diagnostic groups. In contrast, no significant differences were observed between depression scores in the Hwa-byung and non-diagnostic groups. CONCLUSION: These results suggest that PTED may be a disorder category that is distinct from Hwa-byung.
