Objectives Recently, weight loss has emerged as a national concern in South Korea, and this has resulted in an increase in the frequency of use of central nervous system (CNS)-stimulating appetite suppressants. This study aimed to collect cases of psychotic disorders and bipolar disorders triggered by phentermine and phendimetrazine and explore the clinical features and courses. Methods In this retrospective study, we analyzed the electronic medical records of patients and selected eight patients who developed psychotic symptoms and manic symptoms for the first time after taking phentermine and phendimetrazine. All cases were reviewed, and their clinical features and course were summarized. Results All eight patients developed psychotic symptoms, and one had accompanying manic symptoms. The final diagnosis was appetite-suppressant-induced psychotic disorder in four patients, schizophrenia in three, and appetite-suppressant-induced bipolar disorder in one. In addition, three patients were diagnosed as having substance-use disorder. The key psychotic symptoms of these patients were hallucinations and paranoia. Conclusions These case findings suggest that phentermine and phendimetrazine can cause psychotic disorder, bipolar disorder, or substance use disorder and that medical professionals and the public should practice caution when prescribing and using these drugs.

본 연구의 목적은 정신병리를 겪고 있는 정신건강의학과 환자들의 정서 지능의 특징을 능력 모델에 근거하여 살펴보는 것이다. 이를 위해 2가지 대별되는 정서 지능 측정치 즉, 수행기반 검사와 자기보고식 검사 결과를 비교했다. 자기보고가 가능한 환자들 중 정신증 유무로 구분(각 30명, 32명)하여 전체 지능지수에 유의한 차이가 없음을 확인한 후, 두 집단의 정서 교양 검사(수행기반)와 특성 메타-기분 척도(자기보고식) 점수를 독립 표본 t-test로 분석하였다. 분석결과, 정신증적 집단이 비-정신증적 집단에 비해 수행기반 정서 지능 측정치가 통계적으로 유의하게 낮은 반면, 자기보고를 통해 측정된 정서 지능 측정치는 반대 양상을 보였다. 이와 같은 불일치는 정서 지능 측정방식의 차이에서 기인하는 것으로, 정신병리를 겪는 환자들의 정서지능을 평가할 경우에는 수행기반 검사와 자기보고식 검사의 융합적 사용이 중요함을 시사한다.

Objectives : Proinflammatory process has been implicated as an underlying mechanism of bipolar disorder and schizophrenia. Previous studies have suggested a possible role of lymphotoxin alpha (LTA) gene in the development of schizophrenia and have prompted further investigation in bipolar patients. Association of the LTA +252A/G polymorphism with susceptibility to bipolar I disorder itself as well as with vulnerability among a subset of psychotic bipolar patients were tested. Methods : DNA extraction was done by a standard method and genotyping was carried out by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method in 114 Korean patients with bipolar I disorder and 202 healthy controls. SPSS v18.0 was used for statistical analysis. Comparisons of the genotype and allele distributions in LTA +252A/G polymorphism were made using a chi-square test. The genotype and allele associations were also evaluated using odds ratio (OR) and 95% confidence interval (CI). Statistical significance was accepted when p was < 0.05. Results : No significant association was found between the LTA +252A/G polymorphism and bipolar disorder. However, LTA +252G allele was present with significantly higher frequency among bipolar patients with psychotic features compared to those without (${\chi}^2$ = 4.69, p = 0.034, OR = 2.495, 95% CI = 1.069-5.827). Conclusion : The results suggest that the allele LTA +252G of the polymorphism may be associated with the psychotic subset of bipolar disorder but not with bipolar I disorder itself. Adequately powered subsequent studies should be conducted.

Schizophrenia is one of serious mental illnesses and is often described as a heterogeneous disorder. Approximately one-third of schizophrenia cases are treatment-resistant schizophrenia (TRS). The aim of this study was to review the definitions and clinical features of TRS. Though it was found that the criteria for TRS were considerably diverse, the Treatment Response and Resistance in Psychosis (TRRIP) consensus criteria were recently introduced. According to the TRRIP criteria, TRS should be suspected if symptoms persist alongside psychotic symptoms despite sufficient treatment for ≥12 weeks, or two or more symptoms persist significantly for ≥6 weeks. The clinical characteristics of TRS includes an earlier age of onset, more severe and familial form, possibly more rural residence, unlikely association with male sex, and an increase in cognitive deficits.

The Evaluation of patients complaining of psychiatric symptoms following head injury is much affected by the results of various tests. The objecive of this paper is to investigate the effectiveness of each lest by comparing the structual and fuctional brain studies. The subjects were 93 organic menial disorder in and out patients at the Dept. of Neuropsychiatry of the Kyung Hee University Hospital. After carrying out MRI, CT, SPECT, EEG, the results of each were analysed for the sesitivity and ability to detect focal lesion. The degree of inter-test correlations of lest results were also investigated. Furthermore, the characteristic features of psychological tests were studied and the relationship between each of above mentioned tests and psychological test was examined. As for the test sensitivity to diagnosis, the SPECT was the most superior followed by MRI, CT, EEG in thai order. In the case of abnormality, SPECT ranked 1st in detection of focal lesion, followed by MRI, CT in that order. In the inter-test result correlation, the correlation of SPECT-MRI was statistically significant. When mare than moderate abnormality EEG finding was reported, it correlated significantly with that of MRI findings. In the MMPI, the average scores on F, Hs, D, Hy, Pa, Pt, Sc subscales were above 60. Abnormal SPECT group scored significantly high on the F, Pd, Pa, Sc, Ma scales and therefore in comparison ot the SPECT normal group, displayed more psychotic features. In K-WAIS, the mean full scale IQ was down to 77. 23(Verbal IQ : 78.76, Performance IQ : 77.44) but there was no characterogic significant relationship between the lowered to and abnormal SPECT, MRI, CT and EEG results. In conclusion, 1) The SPECT was mast superior in sensitivity and detection of focal lesions. In comparision with other tests, the results of SPECT correlated well with MRI had thus is thought to be very usefull testing method in the evaluation of organic mental disorder patients. 2) The MRI had relatively high sensitivity, ability to detect focal lesion and superior correlation with other test. 3) Although EEG fared less an sensitivity in comparison to other tests, the results of above moderate abnormal grade group and that of MRI correlated significantly. 4) In the MMPI highly scored in F, Hs, D, Hy, Pa, Pt, Sc subscales and abnormal SPECT patients were shown to display more sever psychotic features. There was no significant character relationship between the lowered IQ(in K-WAIS) and abnormal findings on MRI, CT, SPECT, EEG.

Some characteristics of depression in the aged were elucidated. Compared with the previous thoughts, much more attention was given to the biological aspects of depression. However, we have to face up to and solve a variety of enigmas about depression in the aged people. They are:locations and underlying mechanisms in the cerebrum responsible for depression;relationship of senile depression to the presenile one;possible difference(s) between depression with and without psychotic features;possible neurotransmitter differences between senile and presenile depressions. New insights into these areas could bring some lights in the under standing and treatment of depresseion in the aged.

To examine the double-faced thymoleptic(antidepressant and antimanic) effects of risperidone in mood disorders, this article reviews the psychotropic-induced mania, thymoleptic effects of antipsychotics, therapeutic effects of risperidone and risperidone(RIS)-induced mania(RIM) in mood disorders, risk factors of RIM, possible neurochemical mechanism of these thymoleptic effects, pathophysiological and clinical significance of thymoleptic effects, and suggestive clinical guideline of RIS in mood disorders. RIS appeared effective for bipolar disorder at a lower dose than that recommended for schizophrenia, especially in the cases of maintenance of mood stabilizers, and gradual titration from low doses. Manic induction/exacerbation can occur by chance during RIS treatment in mood disorders, schizoaffective disorders, and schizophrenias. The possible risk factors for RIM are refractory mood disorder, especially in bipolar I disorder with poor initial response ; refractory schizoaffective disorders, especially in bipolar type with poor initial response ; refractory chronic schizophrenias, especially with initial responses ; psychotic features ; higher initial doses ; rapid titration ; combined therapy with antidepressants in refractory depression ; and RIS monotherapy in mania/hypomania. RIS is a drug that preferentially block 5-HT2 receptors. The effects of low dose are due mainly to the blockade of 5-HT2 receptors. There are more gradual increase in D2 blockade with increasing dose and this D2 blocking properties become apparent at higher doses. This may be related to a modulation of dopaminergic transmission by 5-HT2 antagonism at lower doses with the direct action of RIS on DA receptors coming into play at higher dose. The serotonergic antagonistic effect may be important for its effects on depressive symptoms. This, together with adequate blo-ckade of D2 receptors, may not necessarily lead to destabilization of mood disorder, but rather to more therapeutic effects. Therefore, this dose-receptor affinity relationship with both antidepressant and antimanic effects according to treatment duration can explain a continuum of antidepressant effect, antimanic effect, behavioral stimulation, and manic/hypomanic induction/exacerbation. It was the recognition of a useful psychiatric side effects by a thoughtful observer with fertile minds that led to their ultimate utilization as psychotropic drugs, i.e., phenothiazine, MAOI, TCA, and lithium. And, in vivo pharmacological challenge by novel psychotropics, as a neurochemical probe, with more specific actions is a useful tool to select pharmacologically homogeneous subgroup of the same phenotypical(clinical) condition, to further study the unknown underlying pathogenesis of various mental illnesses. Finally, RIS may be a useful alternative or adjunctive drug for patients with mood disorders without psychotic features or refractory to treatment with standard antipsychotic drugs. The more conservative doses(tirated slowly from 1-3 mg/d) of RIS, and maintenance of mood stabilizer in the cases with risk factors of RIM are recommended in mood disorder.

목적 : 소아 청소년 정신과 환자에서 비전형 항정신병약물인 risperidone에 대한 효과 및 안전성에 대한 자료를 얻고자 하였다. 방법 : 2001년 1월에서 2002년 6월까지 서울대병원 소아 청소년 정신과 병동에 입원한 환자 중 risperidone이 사용되었던 5.4세에서 17.3세 사이의 환자 31명(남 18, 여 : 13)을 대상으로 후향적인 진료기록지 검토를 시행하였다. 결과 : Risperidone이 사용된 주된 정신과 진단은 정신분열병 및 기타 정신증, 정신병적 증상이 동반된 I형 양극성 장애, 뚜렛장애, 자폐스펙트럼 질환, 혼합형 표현성 및 수용성 언어장애, 주의력결핍 과잉행동장애 및 품행장애, 강박장애 등이었으며 이 중 12명에서 정신지체가 동반되었다. Risperidone사용의 주된 목표 증상은 정신병적 증상(n=13, $41.9\%$), 공격성, 충동성, 과잉행동, 상동증 등과 같은 행동 증상(n=10, $32.3\%$), 만성적이고 심한 틱 증상 (n=8, $25.8\%$)이었다. Risperidone의 효과는 risperidone의 목표 증상에 대한 CGI(Clinical Global Improvement)로 평가되었는데 $67.7\%$에서 중등도 이상의 호전을 보였고 평균 7.5개월 동안 치료효과가 유지되었다. Risperidone의 평균 하루 사용량은 $0.05{\pm}0.1mg/kg$이었으며, 정신병적증상군이 0.07mg/kg로 다른 두 증상군(0.04mg/kg)에 비해 의미 있게 높았다. 부작용으로는 체중증가(n=23)가 가장 흔하였으며 그 외 추체외로계 증상(n=15), 자율신경계증상(n=6), 진정작용(n=5), 고프로락틴혈증(n=2) 등 다양한 부작용이 보고되었다. 그러나 부작용으로 인해 약물을 변경한 경우는 없었으며 외래 마지막 방문 시 $90\%$에서 risperidone을 유지하고 있어 약물내약성은 비교적 우수한 것으로 평가되었다. 결론 : 비전형 항정신병 약물인 risperidone은 정신병적 증상, 공격성, 충동성, 과잉행동, 상동행동을 포함하는 행동증상, 만성적이고 심각한 틱증상 등 다양한 소아 청소년 정신병리의 치료에 비교적 안전하고 효과적인 약물이 될 수 있을 것으로 평가된다. 향후 risepridone의 효과 및 안전성에 대한 보다 장기적이고 체계적인 연구가 필요할 것이다.
