    Article: Early assessment of delirium in elderly patients after hip surgery.
    [show abstract] [hide abstract]
    ABSTRACT: This study is intended to identify predictive factors of delirium, including risk factors and prodromal symptoms. This study included sixty-five patients aged 65 years or older who had undergone hip surgery. Baseline assessments included age; gender; admission type (acute/elective); reason for surgery (fracture/replacement); C-reactive protein (CRP); Acute Physiology, Age, Chronic Health Evaluation (APACHE III); and the Mini-Mental State Examination (MMSE). The Korean version of the Delirium Rating Scale-Revised-98 (K-DRS-98) was used to assess prodromal symptoms daily before the onset of delirium. Almost 28% (n=18) of the 65 patients developed delirium after surgery. Delirium in elderly patients after hip surgery was observed more often in older patients and those with acute admission, hip fracture, higher APACHE III score, lower MMSE score, and higher CRP levels within early days after the operation. Sleep-wake cycle disturbances, thought process abnormalities, orientation, and long-term memory in symptom items of K-DRS-98 were showed significant difference on 4 days before delirium, lability of affect on 3 days before, perceptual disturbances and hallucination, and visuo-spatial ability on 2 days before, and delusion, motor agitation, and short-term memory on the day before the occurrence of delirium. CRP levels within 24 hours and 72 hours after hospitalization were significantly higher in the delirium group. Medical professionals must pay attention to behavioral, cognitive changes and risk factors in elderly patients undergoing hip surgery and to the prodromal phase of delirium. K-DRS-98 may help in identifying the prodromal symptoms of delirium in elderly patients after hip surgery.

    Article: Anger in elderly patients with depressive disorders.
    [show abstract] [hide abstract]
    ABSTRACT: This study was conducted to investigate anger in elderly patients with depressive disorders. The subjects included 216 elderly patients with depression and 198 controls. All subjects were assessed by the State and Trait Anger Inventory (STAXI), Aggression Questionnaire (AQ), Reaction Inventory (RI). Elderly patients with depressive disorder showed lower levels of trait anger and anger expression on the STAXI, lower levels of verbal aggression and hostility on the AQ, and lower levels of anger reaction to the unpredictable disruption and disturbances factor, the embarrassing circumstances factor, and the personal disrespect factor on the RI than the controls. In the depression group, the severity of their depression was positively correlated with the trait anger, state anger, anger expression (except 'anger control') scores on the STAXI; the physical aggression, anger, and hostility scores on the AQ; and the anger reaction to unpredictable disruption and disturbances factor, the embarrassing circumstances factor, and the personal disrespect factor scores on the RI. However, the severity of depression negatively correlated with only anger control on the STAXI. In the linear logistic regression analysis, as there were higher levels of state anger seen in the STAXI, anger on the AQ, anger reaction to unpleasant factors on the RI, and therefore the likelihood of depression would be higher. Elderly depressive patients are less likely to have anger traits and to express anger than normal elderly. However, in elderly depressive patients, the higher they have severity of depressive symptoms, the higher they reported anger experience and anger expression.

    Article: A validation study of the Korean version of SPAN.
    [show abstract] [hide abstract]
    ABSTRACT: The SPAN, which is acronym standing for its four components: Startle, Physiological arousal, Anger, and Numbness, is a short post-traumatic stress disorder (PTSD) screening scale. This study sought to develop and validate a Korean version of the SPAN (SPAN-K). Ninety-three PTSD patients (PTSD group), 73 patients with non-psychotic psychiatric disorders (psychiatric control group), and 88 healthy participants (normal control group) were recruited for this study. Participants completed a variety of psychiatric assessments including the SPAN-K, the Davidson Trauma Scale (DTS), the Clinician-Administered PTSD Scale (CAPS), and the State-Trait Anxiety Inventory (STAI). Cronbach's α and test-retest reliability values for the SPAN-K were both 0.80. Mean SPAN-K scores were 10.06 for the PTSD group, 4.94 for the psychiatric control group, and 1.42 for the normal control group. With respect to concurrent validity, correlation coefficients were 0.87 for SPAN-K vs. CAPS total scores (p<0.001) and 0.86 for SPAN-K vs. DTS scores (p<0.001). Additionally, correlation coefficients were 0.31 and 0.42 for SPAN-K vs. STAI-S and STAI-T, respectively. Receiver operating characteristic analysis of SPAN-K showed good diagnostic accuracy with an area under the curve (AUC) of 0.87. The SPAN-K showed the highest efficiency at a cutoff score of 7, with a sensitivity of 0.83, a specificity of 0.81, positive predictive value (PPV) of 0.88, and negative predictive value (NPV) of 0.73. These results suggest that the SPAN-K had good psychometric properties and may be a useful instrument for rapid screening of PTSD patients.

  • Article: Body Dysmorphic Disorder in a Korean Nurse College Student Sample
    [show abstract] [hide abstract]
    ABSTRACT: Objectives:The purposes of this study were to examine prevalence, characteristics and comorbidity of BDD in Korean nurse college students. Methods:Korean versions of BDDE-SR, MOCI, BDI, SES, LSAS were applied to 607 Korean nurse college students. Results:1) Five factors were extracted in BDDE-SR by factor analysis with the Varimax rotation. They were‘preoccupation, distress, embarrassment factor’,‘avoidance factor’,‘checking, comparing, camouflaging factor’,‘dissatisfaction factor’,‘importance factor’. 2) Sex differences in dissatisfied body parts on whole body, head hair, whole face, genitals, breasts were significant by chi-square test. 3) Eighteen participants(2.97%) were satisfied with DSM-IV criteria A and B of body dysmorphic disorder(BDD group). 4) The most dissatisfied body part was entire leg, eye, nose, waist-abdomen, calves in BDD group. 5) Differences between BDD group and non-BDD group on age and weight were significant by Mann-Whitney U-tests. 6) Differences between BDD group and non-BDD group on BDI, MOCI, LSAS-anxiety scale, LSAS-avoidance scale, SES were significant by Mann- Whitney U-tests. 7) Differences between men and female on BDDE-SR factor 1, BDDE-SR factor 2, BDDE-SR factor 3, BDDE-SR total factors, LSAS-avoidance scale were significant by Mann-Whitney U-tests. 8) Using multiple regression analysis the most contributing variance toward the total factor score of BDDE-SR of participants was BDI, and others were BMI, LSAS-anxiety scale, age, MOCI, SES in order of contribution. Conclusion:Our results indicate that BDD is a common disorder and is highly associated with depression, anxiety, obsessive-compulsive disorder symptoms, poor self-esteem. The authors suggest that future researches should be directed to obtaining clinical data of the patients with BDD.

  • Article: Comparison of efficacy and safety of milnacipran and fluoxetine in Korean patients with major depression.
    [show abstract] [hide abstract]
    ABSTRACT: To compare efficacy and safety of milnacipran and fluoxetine in a population of Korean patients with major depression. The design was a multi-centre, randomised, comparative clinical study. Patients with major depression (DSM-IV diagnostic criteria) scoring over 17 points on the 17-item Hamilton Depression Scale (HAM-D) and over 21 points on the Montgomery-Asberg Depression Rating Scale (MADRS) were recruited and randomised to receive milnacipran (50 mg/day increasing after 1 week to 100 mg/day) or fluoxetine (20 mg/day) for 6 weeks. All previous medication was stopped at least 7 days before entry into the study. Patients were evaluated (HAM-D, MADRS and clinical global impression scale, CGI) at baseline and after 1, 2, 4 and 6 weeks of treatment. All adverse events which developed during the study period were recorded. 70 patients (milnacipran 39; fluoxetine 31) were included in the study. Total score on both HAM-D, MADRS and CGI decreased significantly in both groups after 1 week and continued to decrease throughout the study. There was no significant difference between the two groups for any measurement at any time point. Both antidepressants were well tolerated. In the milnacipran group, 13 patients reported 28 adverse reactions, and in the fluoxetine group 11 patients reported 18 adverse reactions. Two patients discontinued due to adverse events in the milnacipran group and three in the fluoxetine group. There were no clinically significant modifications in vital signs, routine blood laboratory tests, biochemistry or ECG throughout the study. Nausea and headache were the most frequently reported adverse events with milnacipran while digestive disturbances, diarrhoea and insomnia were more common with fluoxetine. Milnacipran, like fluoxetine, was found to be effective and well tolerated for the treatment of major depression in this population of depressed Korean patients. Principal limitations of the study were its open design, its small sample size and its relatively short duration.

    Article: Influence of the serotonin transporter promoter gene polymorphism on susceptibility to posttraumatic stress disorder.
    [show abstract] [hide abstract]
    ABSTRACT: Posttraumatic stress disorder (PTSD) is a prevalent anxiety disorder marked by behavioral, physiologic, and hormonal alterations. The etiology of PTSD is unknown, although exposure to a traumatic event constitutes a necessary, but not sufficient, factor. Serotonergic dysfunction has been implicated in PTSD. The present study examined the possible association between the serotonin-transporter-linked polymorphic region (SERTPR) and PTSD. The genotype and allele frequencies of the SERTPR were analyzed in 100 PTSD patients and 197 unrelated healthy controls using a case-control design. The frequency of the s/s genotype was significantly higher in PTSD patients than in normal controls. These findings suggest that the SERTPR s/s genotype is one of the genetic factors for the susceptibility to PTSD. Further investigations are required into the influence of gene polymorphisms on the biological mechanisms of PTSD, its clinical expression, and its response to treatment.

  • Article: Reliability and validity of the Korean version of the Davidson Trauma Scale.
    [show abstract] [hide abstract]
    ABSTRACT: The Davidson Trauma Scale (DTS) is a validated, 17-item, brief global assessment scale for posttraumatic stress disorder (PTSD). The purposes of this study were to develop a Korean version of the DTS (DTS-K) while maintaining its basic structure and to evaluate its reliability and validity for the Korean population. Participants of this study included 93 patients with PTSD (PTSD group), 73 patients with nonpsychotic mood or other anxiety disorders (psychiatric control group), and 88 healthy controls (normal control group). Subjects completed psychometric assessments, including the DTS-K and the Korean version of the Clinician-Administered PTSD Scale and the State Trait Anxiety Inventory. The DTS-K showed good internal consistency (Cronbach alpha = .97) and test-retest reliability (r = .93). The DTS-K showed a significantly positive correlation with Clinician-Administered PTSD Scale (r = .94). The highest diagnostic efficiency of DTS-K was at a total score of 47, with sensitivity and specificity of 0.87 and 0.84, respectively. Our findings suggest that the DTS-K is composed of good psychometric properties and is a valid and reliable tool for assessing the frequency and severity of PTSD symptoms regardless of ethnicity.
