Microtensile bond strength and micromorphologic analysis of surface-treated resin nanoceramics

PURPOSE: The aim of this study was to evaluate the influence of different surface treatment methods on the microtensile bond strength of resin cement to resin nanoceramic (RNC). MATERIALS AND METHODS: RNC onlays (Lava Ultimate) (n=30) were treated using air abrasion with and without a universal adhesive, or HF etching followed by a universal adhesive with and without a silane coupling agent, or tribological silica coating with and without a universal adhesive, and divided into 6 groups. Onlays were luted with resin cement to dentin surfaces. A microtensile bond strength test was performed and evaluated by one-way ANOVA and Tukey HSD test (α=.05). A nanoscratch test, field emission scanning electron microscopy, and energy dispersive X-ray spectroscopy were used for micromorphologic analysis (α=.05). The roughness and elemental proportion were evaluated by Kruskal–Wallis test and Mann–Whitney U test. RESULTS: Tribological silica coating showed the highest roughness, followed by air abrasion and HF etching. After HF etching, the RNC surface presented a decrease in oxygen, silicon, and zirconium ratio with increasing carbon ratio. Air abrasion with universal adhesive showed the highest bond strength followed by tribological silica coating with universal adhesive. HF etching with universal adhesive showed the lowest bond strength. CONCLUSION: An improved understanding of the effect of surface treatment of RNC could enhance the durability of resin bonding when used for indirect restorations. When using RNC for restoration, effective and systemic surface roughening methods and an appropriate adhesive are required.

The treatment of an edentulous patient with DENTCA(TM) CAD/CAM Denture / 대한치과보철학회지

Nowadays, CAD/CAM is broadly used in dentistry for inlays, crowns, implant abutments and its spectrum is expanding to complete dentures. Utilizing CAD/CAM to fabricate complete dentures is expected to decrease chair time and the number of visits, thus decreasing total fabrication time, expenses and errors caused during fabrication processes. One of the systems using CAD/CAM, DENTCA(TM) CAD/CAM denture (DENTCA Inc. Los Angeles, USA) scans edentulous impressions, designs dentures digitally, fabricates try-in dentures by 3D printing and converts them into final dentures. Patients can wear final dentures after only 2 - 3 visits with satisfying adaptation. This case report introduces a 71-year-old male patient who visited to consult remaking of existing old dentures. Residual teeth with bad prognosis and root remnants were extracted and the patient used reformed existing mandibular denture for 2 months. And then DENTCA system started. One-step border molding was done using conventional tray of adequate size provided by DENTCA system and wash impression was taken. Gothic arch tracing was completed based on the vertical dimension of existing dentures. Both maxillary and mandibular trays were placed to the resultant centric relation and bite registration was taken. Then DENTCA scanned the bite registration, arranged the teeth, completed the festooning and fabricated the try-in dentures by 3D printing. The try-in dentures were positioned, occlusal plane and occlusal relations were evaluated. The try-in dentures were converted to final dentures. To create bilateral balanced occlusion, occlusal adjustment was done after clinical remounting using facebow transfer. The result was satisfactory and it was confirmed by patient and operator.

Usability of Academic Electronic Medical Record Application for Nursing Students' Clinical Practicum / 대한의료정보학회지

OBJECTIVES: Nursing curricula for undergraduate nursing students need to reflect the information technology used in current nursing practice. A smart-device Academic Electronic Medical Record (AEMR) application can help nursing students access and document records for the clinical practicum. We conducted a pilot study to evaluate the usability of an AEMR application before applying it to the clinical nursing practicum. METHODS: A previously developed EMR application was modified as an AEMR to access patient information at bedside and to practice documentation. We added several features to the current EMR application to create an AEMR environment. We created a series of document forms and several useful scales on an external application, which included nursing admission notes, vital signs, and intake/output. The case scenarios and tasks were created by a research team to evaluate aspects of AEMRs, including their usability and functionality. Five nursing students completed 15 tasks using a think-aloud method with a tablet device. RESULTS: Minor usability issues were identified and rectified. All participants indicated that they became familiar with the application with little effort. They said that the application icons were intuitive, which helped them find patient information more quickly and accurately. CONCLUSIONS: The application will improve timely access to patient data and documentation for nursing students. We are confident that this AEMR application will enhance nursing students' experience with their clinical practicum, and help them to better understand patient conditions and document them with ideal accessibility.

Development of Korean Adult ADHD Rating Scale

OBJECTIVES: Symptoms of attention-deficit hyperactivity disorder (ADHD) during childhood may persist into adulthood. This study included the development and validation process of the Korean Adult ADHD Rating Scale (K-AARS), which was developed for screening and monitoring treatment of adults with ADHD. METHODS: Preliminary questionnaires of the K-AARS were based on the reviews of previous adult ADHD scales and clinical experiences of the board certified child and adolescent psychiatrists in Korea. For this study, 136 adults (18-50 years old) with inattention, hyperactivity and/or impulsivity symptoms were enrolled as ADHD subjects, and compared with 406 control subjects (18-50 years old) without ADHD symptoms. Construct validity was examined using explorative factor analysis and Cronbach's alpha to obtain internal reliability coefficients. Concurrent validity was evaluated by comparison with the Conners' Adult ADHD Rating Scale (CAARS). RESULTS: An explorative factor analysis showed that the K-AARS had 8 factors (inattention, hyperactivity, impulsivity, antisocial personality disorder/conduct disorder/oppositional defiant disorder, impairment, driving, emotional dysregulation, disorganization). K-AARS was highly reliable in terms of internal consistency (Cronbach's alpha 0.77-0.95) and correlation between factors (0.57-0.86). Concurrent validity with the CAARS and discriminant validity were statistically significant. CONCLUSION: The K-AARS is a valid and reliable measure for assessment of Korean adults with ADHD.

In vitro study of microleakage of endodontically treated teeth restored with different adhesive systems and fiber-reinforced posts / 대한치과보철학회지

PURPOSE: While studies have examined microleakage in endodontically treated teeth restored with posts, microleakage among post and adhesive systems remains a concern. This study compared the sealing properties of 3 adhesively luted post systems. MATERIALS AND METHODS: Thirty-six endodontically treated permanent maxillary central incisors were divided into 3 groups: Zirconia-glass fiber, Quartz-glass fiber, Polyethylene fiber posts. Post space was prepared and each post was adhesively luted with 3 systems. The specimens were separately immersed in freshly prepared 2% methylene blue solution for 1 week. The cleaned specimens were then embedded in autopolymerizing acrylic resin. The root portion of tooth were horizontally sectioned into three pieces (apical, middle, and coronal portions). An occlusal view of each section was digitally photographed with a stereomicroscope. The methylene blue-infiltrated surface for each specimen was measured. Dye penetration was estimated as the ratio of the methylene blue-infiltrated surface to the total dentin surface. RESULTS: No significant differences were found among post types. The variables of middle section and 3-stage adhesive produced significant differences in microleakage between the following post pairs: zirconia-glass fiber versus quartz-glass fiber, zirconia-glass fiber versus polyethylene fiber, and quartz-glass fiber versus polyethylene fiber (P<.05). There were significant differences between the apical and coronal sections of each post type, and between apical versus middle sections of quarze-glass fiber and polyethylene fiber posts (P<.05). CONCLUSION: No significant differences were found among post types. The 3-stage adhesive produced significant differences in microleakage between the following post pairs.

Additional Retrobulbar Triamcinolone Acetonide Injection for Retrobulbar Optic Neuritis Patients

PURPOSE: To evaluate the effect of additional retrobulbar triamcinolone acetonide (TA) injection on early recovery of visual acuity in retrobulbar optic neuritis patients. METHODS: A prospective, randomized clinical study including 30 patients with retrobulbar optic neuritis was conducted between March 2003 and June 2007. Patients were divided into 2 groups: Group 1 (n = 9) with retrobulbar triamcinolone (TA, 40 mg/1 ml) injection on the first day of ONTT protocol, and group 2 (n = 21) with conventional ONTT protocol. The following parameters were measured and analyzed: patient's sex, age, pupillary reactions, color vision, visual field, and best-corrected visual acuity before treatment, and after 1 day, 1 week, 2 weeks, 1 month, and 3 months of follow-up. RESULTS: Mean visual acuity before treatment was 1.00 +/- 0.89 log MAR units in group 1 and 0.98 +/- 0.75 log MAR units in group 2. One day after injection, visual acuity was better in group 1 (0.50 +/- 0.42 log MAR units) than in group 2 (0.73 +/- 0.61 log MAR units), however, there was no statistically significant difference between the 2 groups (p = 0.07). There was no significant difference in visual acuity, recovery of RAPD, color vision, or visual field at 3 months of follow-up. No serious side effect related to retrobulbar TA injection was observed. CONCLUSIONS: Additional retrobulbar TA injection may help optic neuritis patients who have a need for prompt visual recovery. However, further studies are required to ascertain whether this procedure can help early recovery of visual acuity in retrobulbar optic neuritis patients.

Environmental and Familial Risk Factors of Children and Adolescents with Attention Deficit/Hyperactivity Disorder / 신경정신의학

OBJECTIVES: The aim of this study was to analyze the environmental and familial variables associated with attention-deficit/hyperactivity disorder (ADHD) in children and adolescents. METHODS: Children and adolescents aged 6-18 with in attention, hyperactivity, or impulsivity who visited the Department of Psychiatry at Soonchunhyang University Bucheon Hospital from April 2006 to April 2012, were interviewed for diagnosis of ADHD. Diagnostic and Statistical Manual of Mental Disorders, 4th edition symptom criteria for ADHD were assessed using a semi-structured interview, the schedule for affective disorders and schizophrenia for school-age children present and lifetime version (K-SADS-PL). Environmental and familial variables were obtained using questionnaires for parents. RESULTS: In total, 262 children and adolescents with ADHD (n=139) and control subjects (n=123) were recruited. In a multivariate logistic regression model, results of this study showed that maternal psychiatric problem during pregnancy, dystoia, forceps/vacuum use during delivery, and unplanned pregnancy were risk factors for ADHD. CONCLUSION: Findings of this study showed an association of some prenatal factors (such as unplanned pregnancy or maternal psychiatric problem during pregnancy) and some perinatal factors (dystocia and forceps/vacuum use during delivery) with increased risk of ADHD. The identified risk factors are environmental, and therefore potentially preventable. Conduct of further prospective studies is needed in order to clarify the potential role of these risk factors for ADHD.

Efficacy and Safety of Topical Unpreserved 0.1% Fluorometholone Ophthalmic Solution on Dry Eye Syndrome

PURPOSE: To evaluate the efficacy and safety of topical unpreserved 0.1% fluorometholone (FML) ophthalmic solution in patients with dry eye syndrome. METHODS: Patients with mild to moderate dry eye syndrome were divided into the control group (Group I), topical unpreserved 0.1% FML group (Group II), and topical preserved 0.1% FML group (Group III). Intraocular pressure (IOP), Ocular Surface Disease Index (OSDI), tear film break-up time (TF-BUT), Oxford stain score (OSS), and tear osmolarity (Tosm) were evaluated at 2 weeks, 4 weeks, 8 weeks, and 12 weeks (Trial 1). Patients with severe dry eye syndrome were divided into 1% methylprednisolone (MP) group (Group I) and 0.1% unpreserved FML group (Group II). Same parameters were evaluated in both groups (Trial 2). RESULTS: In clinical trial I, OSS scores of Group II were lower than other groups (p < 0.05). For severe dry eye patients in clinical trial 2, there were no significant differences in all parameters between the 2 groups. CONCLUSIONS: Topical unpreserved 0.1% fluorometholone was shown to be an effective and relatively safe treatment in patients with dry eye syndrome.

The Trend of the Use of Neuropsychological Tests in the Korean Psychiatric Division for the Past 10 Years : Focused on Dementia Research / 신경정신의학

OBJECTIVES: The aim of this study is to investigate the proportion of dementia studies and the trends of the use of neuropsychological tests in dementia studies for the past 10 years. METHODS: The subjects of this study were 715 original articles published in Journal of Korean Neuropsychiatric Association and 72 original articles published in Journal of Korean Geriatric Psychiatry between January 1, 2000 and December 31, 2009. Among those, there were 78 articles of dementia study and 36 articles using the neuropsychological test used for the analysis. According to the published year, all articles were divided into two stages (between 2000-2004, between 2005-2009). The data were collected for what neuropsychological tests were used. RESULTS: The proportion of dementia studies increased from 8.2% to 12.4% and the proportion of dementia studies using the neuropsychological test decreased from 60.5% to 37.5%, when comparing the two stages. The use rate of screening tests, intelligence tests, and domain-specific cognitive tests decreased from 91.3% to 84.6%, 13.0% to 0%, 91.3% to 76.9% respectively, whereas the use rate of comprehensive assessment of dementia increased from 21.7% to 38.5%. CONCLUSION: These results show an increasing trend in dementia studies and decreasing rate of neuropsychological test use in Korea. However, the use rate of comprehensive assessment of dementia increased.

Screening Oppositional Defiant Disorder with the Korean Child Behavior Checklist : The Role of the Subscales of Aggressive and Delinquent Behavior

OBJECTIVES: This present study examined the power of the Korean Child Behavior Checklist (K-CBCL) subscales to predict a DSM-IV diagnosis of oppositional defiant disorder (ODD). METHODS: The sample included 37 children and adolescents with ODD and 46 normal controls. The participants and their parents were interviewed for clinical diagnosis using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version (K-SADS-PL) and the parents completed the K-CBCL. Logistic regression analysis was used to predict the diagnosis of ODD. RESULTS: Among the CBCL subscales, Delinquent and Aggressive Behavior scales significantly predicted ODD diagnosis. The means of these CBCL subscales were significantly higher in the ODD group when compared to the controls. CONCLUSION: Two CBCL subscales (Deliquent and Aggressive Behavior) displayed good diagnostic efficiency for assessing ODD in children and adolescents. Through combining information from the CBCL, an empirical-quantitative approach to psychopathology in children and the DSM-IV diagnostic criteria, the results demonstrated that a clinical diagnostic approach is an effective diagnostic paradigm for children with ODD.

Reliability and Validity of the Child and Adolescent Functioning Impairment Scale in Children with Attention-Deficit/Hyperactivity Disorder

OBJECTIVE: The purpose of the present study was to develop reliable and valid parent and teacher scales for measurement of functional impairment in children and adolescents in order to assist the diagnosis of attention-deficit/hyperactivity disorder (ADHD). METHODS: Seventy-two children with ADHD fulfilling the Diagnostic and Statistical Manual of Mental Disorder, 4th Edition criteria and forty-two normal controls were enrolled in this study. Parents and teachers of the subjects completed the parent and teacher form of the preliminary items of Child and Adolescent Functioning Impairment Scale (CAFIS) made up by the authors. Based on the reliability and factor analysis, the final parent (CAFIS-parent form) and teacher version (CAFIS-teacher form) were constructed. Scales were analyzed for reliability and validity. Relative operating characteristics curve was drawn to calculate the cutoff scores of these scales for children with ADHD. RESULTS: The CAFIS-parent and CAFIS-teacher forms consist of four and three factors, respectively. Internal consistency and test-retest correlation of the scales were satisfactory. The CAFIS and Children's Global Assessment Scale were significantly correlated. All scores of subscales of CAFIS in ADHD group were significantly higher than those of control group. The sensitivity and specificity of the subscales were mostly at an appropriate level. CONCLUSION: The CAFIS is a brief layperson-administered scale to assess functional impairment of children and adolescents. It can be a useful tool for parents and teachers to objectively measure the functions of children at home and in school. This scale was found to be reliable and valid, and it appears to be a valuable instrument in Korean language.

Eight Years of Follow-Up Study with Regard to Defense Mechanisms in Medical Students / 신경정신의학

OBJECTIVES: The purpose of this study was to evaluate the changes in defense mechanisms in medical students as they progress towards becoming a doctor. METHODS: Ninety premedical students were enrolled from Soonchunhyang University. All subjects were evaluated at baseline, during their 6th year of medical school, during their 4th year as a practicing doctor by the Ewha defense Mechanisms Test which contained 20 defense mechanisms and 4 factors (unstable, narcissistic, self-negative, and avoidant). In the end, 60 subjects were included in the analysis. RESULTS: During the period from premedical student to medical doctor, the use of passive-aggressive, acting-out, displacement, somatization, dissociation, projection, denial, regression, and distortion decreased significantly. Also, there was a significant difference in the use of defense mechanisms from the time as a premedical student to a medical student. However, there was no significant difference in the period from medical student to medical doctor. CONCLUSION: We concluded that the use of unstable and avoidant defense scales decreased in the course of becoming a doctor from a premedical student, compared to mature or stable defense scales.

Comparison of Working Memory Among the Subtypes of Child and Adolescent Attention-Deficit/Hyperactivity Disorder

OBJECTIVES: This study investigated the differences of working memory among the subtypes of ADHD. METHODS: Eighty-one children and adolescents with ADHD and thirty normal controls were recruited. Children with any cognitive disorders and low intelligence were excluded. In order to evaluate the verbal and visuospatial working memory, Digit span and Finger windows tasks were measured, respectively. Performances on these measures between children with ADHD and controls were compared. Further, performances among the groups of ADHD predominantly inattentive(ADHD-IA)(n=40), predominantly hyperactive-impulsive(ADHD-HI)(n=10), and combined type(ADHD-C)(n=31), were compared. RESULTS: Scores of Finger windows forward task were lower in the ADHD group as compared to the control group, whereas, the Digit span forward showed no difference. Both scores of Digit span backward and Finger windows backward task were lower in the ADHD group than the controls. Children with ADHD-IA performed poorer than children with ADHD-C on the Finger windows backward task. CONCLUSION: The results of this study showed that children with ADHD have deficits in spatial short-term memory and verbal and visuospatial working memory when compared to normal children. The deficits were evident in children with ADHD-IA subtype and in particular, performance on the visuospatial working memory task in this group was poorer than the ADHD-C group.

Differentiating PTSD from Malingering:Considerations Interview Style and Typical Symptoms / 신경정신의학

It can be difficult to distinguish posttraumatic stress disorder (PTSD) from malingering because a person's responses after experiencing trauma depend on self-report, such as subjective complaints, and it is easy to find the diagnostic criteria for PTSD through the internet or other mass media. Therefore, it is important for clinicians to perceive patients' motivations and determine whether they have external incentives. We reviewed clinicians' and patients' interview styles, which can be useful for reducing malingering intent and detecting malingering patterns. To help clinicians differentiate PTSD from malingering, we also reviewed the diagnostic criteria (re-experience, avoidance and numbing, and hyperarousal) and the typical symptoms of true and malingered PTSD.

Comparison on the Efficacy of Quetiapine Versus Haloperidol in the Treatment of Delirium: Prospective, Randomized Trial

OBJECTIVES: The purpose of this study is to examine the efficacy and side effects of quetiapine and haloperidol for the treatment of symptoms of delirium. METHODS: One hundred and seven patients with delirium were recruited and randomly assigned to receive a flexible-dose regimen of quetiapine or haloperidol over 7days and seventy-seven patients completed the study(quetiapine group N=40, haloperidol group N=37). The severity of delirium was assessed by using Memorial Delirium Assessment Scale(MDAS) scores, the psychiatric and behavioral symptoms were assessed by Neurobehavioral Rating Scale(NRS) scores, and the cognitive status was measured by Mini-mental state examination Korean version(MMSE-K) scores. The side effects were measured by Drug Induced Extrapyramidal Symptoms Scale(DIEPSS) scores. RESULTS: MDAS scores significantly improved in both treatment groups. NRS scores also significantly improved in both treatment group, but the group-by-time effect approached significance, likely caused by the greater decrease in scores of the quetiapine group. MMSE-K scores significantly improved only in the quetiapine group. Side effects associated with treatment were not significant in either treatment groups. CONCLUSION: This study suggests that quetiapine is as efficacious as haloperidol in the treatment of delirium. In particular, quetiapine seems to improve psychiatric and behavioral problems of delirium and was more effective than haloperidol in cognitive improvement.

Development of the Korean Somatization Scale for Children: An Investigation of Reliability and Validity

OBJECTIVES: The purpose of this study was to develop the Korean Somatization Scale for Children (KSS-C) and to evaluate the reliability and validity of this scale. METHODS: Sixty-five children and adolescents with somatic symptoms were evaluated the KSS-C, Child Version, the Children's Depression Inventory (CDI), and the State-Trait Anxiety Inventory for Children (STAIC). 65 parents of the subjects evaluated the KSS-C, Parent Version and Korean version of the Child Behavior Checklist (K-CBCL). Psychometric properties and associations with the internalizing symptoms were. RESULTS: Three factors were extracted by factor analysis. KSS-C was significantly correlated with the CDI, the STAIC, and the internalization, externalization and somatization scale of the K-CBCL. The KSS-C, Parent Version was significantly correlated with the KSS-C, Child Version. Frequently reported somatic symptoms in children were fatigue, headache, low energy, stoma-chache, and nausea. CONCLUSION: Both KSS-C, Child Version and KSS-P, Parent Version were valid and reliable instrument assess somatic symptoms in Korean children and adolescents.

A Prospective Study on Changes in Health Status Following Flood Disaster

OBJECTIVE: We examined changes in general health status, the prevalence of depression and post-traumatic stress disorder (PTSD) symptoms, and the existence of pre-trauma contributing factors in an agricultural population following a massive flood. METHODS: Eighty-three of 160 residents of Garisan-ni, Inje-gun, Gangwon-do, were assessed using the Korean version of the 36-Item Short-Form Health Survey (SF-36-K) between April and June 2006, just prior to a massive flood. Among those initially assessed, 58 residents were available for follow-up 18 months after the flood. Participants completed the SF-36-K, Beck Depression Index (BDI), Minnesota Multiphasic Personality Inventory (MMPI)-PTSD, and the Korean version of the Impact of Event Scale-Revised (IES-R) to detect depression and PTSD. Trauma experiences were also assessed. Factors related to changes in health status were then analyzed. RESULTS: SF-36-K total scale scores decreased significantly, suggesting a significant reduction in health-related quality of life. The largest reductions were noted in physical and social functioning. Fifty-three percent of the subjects were at least mildly depressed, and 17% had severe depression. In addition, 22% had PTSD on both the IES-R and MMPI-PTSD. Factors that contributed to the deterioration of health status following the flood were the number of disaster events and existence of depression (as assessed by the BDI). CONCLUSION: The flood was found to lead to deterioration of health status and to provoke depression and PTSD among the agricultural population in the mountainous region. We suggest that the number of disaster event experiences and existence of depression contriuted to changes in health status after the flood.

The Effect of Attention on Executive Function in Traumatic Brain Injury Patients: Testing for Stage Model

OBJECTIVES: The purpose of this study was to test stage model in Traumatic Brain Injury(TBI) patients. According to the stage model, attention deficits which is basic stage in information processing lead to memory disturbance and subsequently affect higher-order cognitive function such as memory, decision-making, abstract thinking, and judgement related to executive function. Therefore, it was hypothesized that attention affect recall(retrieval efficacy) related to executive function mostly relative to other cognitive function, in TBI patients with low executive function. METHODS: Participants were referred to a TBI clinic and then was rated on K-WAIS and Executive Intelligence Test(EXIT). Participants were divided into two groups according to Executive IQ(EIQ) score, which of high function group(N=67) was more than 80(above low average) and of low function group(N=52) was under 80 (under borderline). To test the stage model, using hierarchical regression analysis, recall(retrieval efficacy) was regressed on 3 subscales(attention, verbal, visuospatial scale) after controlling for IQ according to each group. Furthermore, the mediation effect of attention between retrieval efficacy and verbal, visuospatial score was analyzed. RESULTS: In the low function group, only attention area predicted significantly recall(retrieval efficacy), indicating that lower attention were related to lower EIQ after controlling for IQ. In the high function group, no area predicted significantly retrieval efficacy. In the low function group, verbal and visuospatial scale did not predicted significantly retrieval efficacy, indicating that there was no evidences supporting the mediation model. CONCLUSION: Only attention affect retrieval efficacy in TBI patients with low executive function. But, the mediation effect of attention between retrieval efficacy and verbal and visuospatial scale was not tested in the low function group. These results implied that stage model was tested partially. In treating cognitive deficit in TBI patients, it is necessary to develop cognitive rehabilitation program based on stage model. Furthermore, it is necessary to necessary to test mediation model in the future study.

The Cognitive Characteristics of Somatizer according to Depressive Symptoms and Sex / 신경정신의학

OBJECTIVES: Recent researchers on the mechanism of somatization adapted the view of cognitive theory. A few studies were carried out on the studies of the difference of characteristics in various somatizers in Korea. The aim of the study was to investigate the differences of somato-sensory amplification and symptom interpretation in accation to depressive symptoms and sex. Furthermore, we investigated the relationship of somatosensory amplification and symptom interpretation to somatization in relation to depressive symptoms and sex. METHODS: The somatization scale of SCL-90-R, the depression scale of MMPI, Somato-sensory Amplification Scale (SSAS), and Symptom Interpretation Questionnaire (SIQ) were administered to 299 somatizers. Using independent t-test, we compared the difference of the mean score of SSAS and SIQ in each group. In addition, using stepwise multiple regression analysis, somatization scale was regressed on SSAS and SIQ subscales. RESULTS: Compared with each group, depressive somatizer's mean score of SSAS, SIQ physical, SIQ psychological, and SIQ catastrophic interpretation were significantly higher than non-depressive somatizer's. And female somatizer's mean score of SSAS were significantly higher than male somatizer's. As the results of regression analysis, indicate in depressive somatizer, SSAS, SIQ physical, and SIQ psychological interpretation predicted somatization, indicating that higher SSAS, SIQ physical, and psychological interpretation were related to somatization. Furthermore, in the female somatizer, SSAS, SIQ physical, and SIQ psychological interpretation predicted somatization, indicating that higher SSAS, SIQ physical, and SIQ psychological interpretation were related to somatization. On the other hands, in the male somatizer, SSAS and SIQ catastrophic interpretation predicted somatization, indicating that higher SSAS and SIQ catastrophic interpretation were related to somatization. CONCLUSION: These results suggested that the depressive somatizer amplified their somato-sensory perceptions because they internalized to depressive symptoms. In addition, these results suggest that because female somatizer tends to attribute somatic symptoms more to physical illnesses and to amplifiy their somato-sensory perceptions in comparison with male somatizer, female complains more somatic symptoms thus more prevalence of somatization disorder than male.

A Case of Lichen Nitidus on the Palm / 대한피부과학회지

Lichen nitidus is an uncommon chronic inflammatory disease characterized by multiple minute discrete flesh-colored dome shaped papules. Its distribution is frequently localized on trunk, arm or penis. There are a few cases reported to occur on palm and sole. We report a case of lichen nitidus which presents erythematous or brownish colored hyperkeratotic plaques, composed of 1-2 mm sized small papules on the right palm. Its hitopathologic findings were consistent with a diagnosis of lichen nitidus.
