Angiogenesis is a series of processes that include endothelial proliferation, migration and tube formation. Vascular endothelial growth factor (VEGF) is regarded as a potent mediator of angiogenesis, vascular permeability and tumor cell growth in renal cell carcinoma. This study was designed to evaluate the expression of VEGF and the microvessel count (MVC) and to determine their prediction efficacies for prognosis in renal cell carcinoma. The relationship between the expression of VEGF and MVC were evaluated immunohistochemically in 50 patients with renal cell carcinoma who received a radical nephrectomy at Wonju Christian Hospital between 1989 and 1997. Microvessels were identified by immunostaining endothelial cells for CD-31 antigen. The mean follow-up was 96 months (3 - 133 months). Overall 5-year survival rate was 71.5%. VEGF was expressed in the tumor cell cytoplasm. Of the 50 tumors, 23 (46%) were weak to strongly positive for VEGF but 27 (54%) were unreactive. The respective 5-year survival rates for patients with positive and negative expressions of VEGF were 70% and 73% (p > 0.05). The overall mean MVC was 13.4 in a 400x field. Mean MVCs were significantly higher in VEGF-positive tumors (17.6 +/- 12.1) than in VEGF-negative tumors (9.9 +/- 5.4), and the MVCs of the high vascular density group and the low ascular density groups were significantly different. The 5-year survival rates of patients with high vascular density and low vascular density were 59% and 86%. The median survival period for patients with MVCs higher than or equal to 10 vessels/field was 85 months, whereas for those with MVCs lower than 10 vessels/field the median survival time was 102 months. These results suggest that MVC may be a better prognostic factor in renal cell carcinoma than the expression of VEGF.

BACKGROUND: Psoriasis is a common chronic skin disorder characterized by hyperproliferation of the epidermis, inflammatory cell accumulation and increased tortuosity and dilatation of dermal papillary blood vessels. Angiogenesis plays a major role in the pathogenesis of psoriasis, however the mechanism responsible is largely unknown. Recently, some studies have identified several angiogenic factors from psoriatic epidermis, including interleukin (IL)-8, vascular endothelial growth factor (VEGF), and basic fibroblast growth factor (bFGF). OBJECTIVE: This study was aimed to elucidate the roles of VEGF and bFGF in the pathogenesis of psoriasis. METHODS: Immunohistochemical staining for VEGF and bFGF was carried out on skin samples of 15 psoriatic patients, plus 5 normal skin samples as a control. The psoriatic skins were divided into early and fully-developed stages, and differences in their expression between the stages were examined. RESULTS: The expressions of VEGF and bFGF on both epidermis and dermal structures were significantly higher in psoriatic lesional skin than in normal control skin. There was no significant differences between early and fully- developed psoriatic skin lesions. CONCLUSION: These results suggest that VEGF and bFGF may play significant roles in the pathogenesis of psoriasis.

PURPOSE: The aims of this study were to suggest a method of fabrication of the record base using a light-polymerized resin by applying the two-phase fabrication method for the improvement of the fit of the record base and to compare the degree of fit according to the separation site. MATERIAL AND METHODS: In the edentulous cast of maxilla, four test groups were considered. In the first, second, third, and fourth test groups (n = 12 in each group) the separation was done at 0, 5, 10, and 15 mm, respectively below the alveolar crest along the palatal plane. For the control group, the record base was made without separating the two sections. The light-body silicone material was injected into the fitting surface of the record base. It was then placed onto the cast and finger pressure was applied to stabilize it in a seated position followed by immediate placement onto the universal test device. Finally, the mass of the impression material was measured after it was removed. ANOVA was performed using the SAS program. For the post-hoc test, the Wilcoxon Rank-Sum test and the Tukey-Kramer HSD test were performed (alpha = 0.05). RESULTS: The control group and Group 3, 4 showed significant differences. The Group 3 and 4 showed significantly smaller inside gaps than the control group which was not made with the two-phase fabrication method. CONCLUSION: The two-stage polymerized technique can improve the fit of the denture base particularly when the separation was made at 10 to 15 mm from the alveolar crest.

OBJECTIVE: A Comparison of QTc prolongation for various antipsychotics and an analysis of QTc prolongation for the various types of serotonin transporter polymorphism were performed. METHOD: EKG was checked, followed by QTc measurement as Bazett's correction, and the serotonin transporter polymorphism was examined in 110 chronic schizophrenia patients were performed EKG before 24 weeks ago. We defiened QTc prolongation as over 450ms. The risk factor of sudden cardiac death were defiend as QTc prolongation and or 60ms in delta value. RESULT: The prevalence of QTc prolongation in this study was 7.3%, and the prevalence of over 60ms was 4.5%. Patients who had the risk factors were 10(9.1%). 6/52 who prescribed atypical antipsychotics and 2/58 who prescribed haloperidol showed QTc prolongation. The prevalence who had the risk factor of sudden cardiac death were 16% in atypical antipsychotics group, 3.4% in haloperidol group. QTc prolongation were observed more frequently in l/l type than s/s type. l allele frequency were 50% in QTc prolongated group, 19% in not prolongated group. l allele had an association with QTc prolongation(p<0.01). CONCLUSION: The prevalence of QTc prolongatin was frequent in chronic schizophrenia patients who were prescribed atypical antipsychotics. It has strong association with l allele of 5-HTTLPR.

Objective:
We conducted a systematic review and meta-analysis of the tissue adequacy and complication rates of percutaneous transthoracic needle biopsy (PTNB) for molecular analysis in patients with non-small cell lung cancer (NSCLC).
Materials and Methods:
We performed a literature search of the OVID-MEDLINE and Embase databases to identify original studies on the tissue adequacy and complication rates of PTNB for molecular analysis in patients with NSCLC published between January 2005 and January 2020. Inverse variance and random-effects models were used to evaluate and acquire meta-analytic estimates of the outcomes. To explore heterogeneity across the studies, univariable and multivariable metaregression analyses were performed.
Results:
A total of 21 studies with 2232 biopsies (initial biopsy, 8 studies; rebiopsy after therapy, 13 studies) were included.The pooled rates of tissue adequacy and complications were 89.3% (95% confidence interval [CI]: 85.6%–92.6%; I2 = 0.81) and 17.3% (95% CI: 12.1%–23.1%; I2 = 0.89), respectively. These rates were 93.5% and 22.2% for the initial biopsies and 86.2% and 16.8% for the rebiopsies, respectively. Severe complications, including pneumothorax requiring chest tube placement and massive hemoptysis, occurred in 0.7% of the cases (95% CI: 0%–2.2%; I2 = 0.67). Multivariable meta-regression analysis showed that the tissue adequacy rate was not significantly lower in studies on rebiopsies (p = 0.058). The complication rate was significantly higher in studies that preferentially included older adults (p = 0.001).
Conclusion
PTNB demonstrated an average tissue adequacy rate of 89.3% for molecular analysis in patients with NSCLC, with a complication rate of 17.3%. PTNB is a generally safe and effective diagnostic procedure for obtaining tissue samples for molecular analysis in NSCLC. Rebiopsy may be performed actively with an acceptable risk of complications if clinically required.

Objective:
Attention-deficit/hyperactivity disorder (ADHD) is prevalent in adults, and psychiatric comorbidities are common in adults with ADHD. We aimed to examine the prevalence of adult ADHD with several common psychiatric conditions in a community sample in Korea and the association between adult ADHD and risk of psychiatric comorbidities.
Methods:
This study used a cross-sectional survey design. We provided supplementary and optional self-report questionnaires, including the Korean version of the World Health Organization Adult ADHD Self-Report Scale (ASRS) short screening scale, Patient Health Questionnaire-9 for screening for depression, Alcohol Use Disorders Identification Test alcohol consumption questions, and the Korean version of the Mood Disorders Questionnaire, to Korean adults who visited one of six centers of a large private healthcare company for the National General Health Examination.
Results:
A total of 17,799 subjects included in this study, and 430 (2.4%) were positive on the ASRS screen. ADHD was significantly associated with the 19−30-year-old age group (odds ratio [OR] = 3.938), lower income (OR = 1.298), depression (OR = 11.563), and bipolar disorder (OR = 3.162).
Conclusion
Adult ADHD was highly associated with depression and bipolar disorder, suggesting that clinicians should carefully evaluate and treat such psychiatric disorders in adults with ADHD symptoms.

OBJECTIVE: It is well known that treatment with quetiapine can easily cause somnolence and daytime sleepiness in patients with bipolar disorder. Such sedation may be the discomfort to the drug in terms of patient's perspectives and results in drug noncompliance. This study was aimed to investigate the effect of 6-week quetiapine monotherapy on subjective aspects of sleep in patients with acute bipolar disorder. METHODS: In a Korean multi-center, open-label, 6-week study, patients with a DSM-IV diagnosis of bipolar I disorder (manic or mixed episodes) were included to treatment with quetiapine. The dose of quetiapine initially started at 200 mg/day and rapid titrated up to 800 mg/day within day 7 according to the clinical judgements. Clinical improvement was evaluated using Young Mania Rating Scale (YMRS) and Clinical Global Impression-Bipolar version (CGI-BP). Extrapyramidal side effects were measured by Simpson-Angus Rating Scale (SARS) and Barnes Akathisia Rating Scale (BARS). The overall subjectively reported adverse events were gathered during the study period. Subjective sleep questionnaire modified from Leeds Sleep Evaluation Questionnaire (LSEQ) was used to assess the subjective measures of sleep, which included the aspects covering the ease of getting to sleep (GTS), quality of sleep (QOS) and hangover behavior next day (HOV). All assessments were done at baseline and days 7, 14, 21 and 42 after treatment with quetiapine. Analyses were focused to compare the differences between pre-drug baseline and post-treatment with quetiapine. RESULTS: Total 78 (male=30, female=48) patients were included and most of them were inpatients (N=59, 74.7%). Fifty-nine (75.9%) patients were completed the study. Mean changes of YMRS from baseline were significant at days 7, 14, 21 and 42. There were no significant differences from baseline in SARS and BARS at any assessment points. The common subjectively reported adverse events were somnolence, dizziness and dry mouth. While mean changes of 5 items measuring nighttime sleep (GTS and QOS) from baseline were significantly improved at days 7, 14, 21 and 42, those of HOV were not differed between baseline and post-treatment assessments. CONCLUSION: Data showed that quetiapine monotherapy had favorable effect on acute manic symptoms and well tolerated. Also this result suggests that quetiapine monotherapy may improve the self-perceived quality of sleep without any daytime impairment following sleep in acute manic patients.

OBJECTIVE: Recently, the atypical antipsychotics such as quetiapine, olanzapine, risperidone, aripiprazole and ziprasidone are increasingly used in the management of acute manic patients as the monotherapy. But there are only a few reports on the use of these drugs in the treatment of bipolar disorder in Korea. The aim of this study was to evaluate the efficacy and tolerability of quetiapine monotherapy in patients with acute mania. METHOD: This study is multi-center, open-label, 6-week evaluation of the efficacy of quetiapine in bipolar mania. In this study, patients with a DSM-IV diagnosis of bipolar I disorder (manic or mixed episodes) were included to treatment with quetiapine (flexibly dosed up to 800 mg/day). Clinical improvements were rated by Young Mania Rating Scale (YMRS), Clinical Global Impression-Bipolar Version (CGI-BP), Brief Psychiatric Rating Scale (BPRS) and Montgomery-Asberg Depression Rating Scale (MADRS). Adverse events were measured using Simpson-Angus Rating Scale (SARS) and Barnes Akathisia Rating Scale (BARS), and subjective reports of patients were evaluated. Global Assessment Scale (GAS) was used to evaluate the general functioning of patients. All assessments were done at baseline and at days 7, 14, 21, and 42 except GAS (at days 21 and 42). Analyses were focused on change from baseline to day 42. RESULTS: Total 78 (male=30, female=48) patients were included and 59 patients (75.6%) completed the study. The mean initial dose of quetiapine was 268.0+/-223.2 mg/day and mean daily dose at day 42 was 585.3+/-244.5 mg/day. YMRS and CGI-BP were significantly improved at day 7, 14, 21, and 42 as compared to baseline. Mean scores of BPRS and MADRS were also significantly decreased at the each assessment points. Fifty-two patients (66.7%) showed response (more than 50% of decrease in YMRS score from baseline) and 35 patients (44.6%) reached remission (YMRS score < or =12) at day 21. GAS showed the improvements of patient's global functioning at days 21 and 42 of quetiapine monotherapy compared to baseline. There was no significant difference between baseline and any assessment points on SARS and BARS scores. CONCLUSIONS: The data showed that quetiapine monotherapy has favorable effects across a broad range of mood symptoms with minimal adverse events in addition to functional improvement in acute manic patients. This result suggests that quetiapine may be preferred for patients with acute mania as one of the first-line agents.

OBJECTIVE: Although atypical antipsychotics are increasingly being used as monotherapy in acute mania, few Korean studies have investigated on them. This study evaluated the efficacy and tolerability of olanzapine monotherapy in patients with acute mania. METHODS: This multicenter, open-label study evaluated the efficacy of olanzapine to treat mania over 6 weeks. Patients with a DSM-IV diagnosis of bipolar I disorder (manic or mixed episodes) were treated with olanzapine (flexible dosage to a maximum of 30 mg/day). Clinical improvements were rated using the Young Mania Rating Scale (YMRS), Clinical Global Impression-Bipolar Version (CGI-BP), Brief Psychiatric Rating Scale (BPRS), and the Montgomery-Asberg Depression Rating Scale (MADRS). Adverse events were measured using the Simpson-Angus Rating Scale (SARS) and Barnes Akathisia Rating Scale (BARS). The general functioning of patients was assessed using the Global Assessment Scale (GAS). All assessments were carried out at baseline and at days 7, 14, 21, and 42, with the exception of the GAS. RESULTS: The subjects comprised 76 patients (male=38, female=38), with 55 patients (72.4%) completing the study. The mean initial dose of olanzapine was 11.7+/-5.0 mg/day and mean daily doses at days 7, 14, 21, and 42 were 16.6+/-5.2, 17.2+/-5.0, 18.1+/-5.3, and 17.4+/-4.7 mg/day, respectively. At days 7, 14, 21, and 42, YMRS, CGI-BP, MADRS and BPRS scores had significantly improved from baseline. More improvement in MADRS scores was observed among patients with mixed mania than patients with euphoric mania. Changes in BPRS scores from baseline did not differ between patients with psychotic symptoms and those with euphoric mania. At days 21 and 42, 42 (55.3%) and 57 (75.0%) patients had responded (YMRS scores decreased from baseline by more than 50%). Also 27 (35.5%) and 46 (60.5%) patients had achieved remission (YMRS scores < or =12) at the same assessment points. GAS scores at days 21 and 42 indicated that olanzapine monotherapy improved patients' global functioning compared to baseline. SARS and BARS scores did not differ significantly between pre- and post-drug trial. CONCLUSION: The data indicate that olanzapine monotherapy has favorable effects across a broad range of mood symptoms and yields functional improvement in acute manic patients with minimal adverse events. Therefore, olanzapine monotherapy may be a preferred first-line agent to treat patients with acute mania. These results support the findings from previous studies and guidelines.
