PURPOSE: We analyzed disease free survival and the prognostic factors of liposarcoma in the extremity. MATERIALS AND METHODS: Between 1994 and 2005, of 44 patients who were diagnosed and treated for liposarcoma of the extremity, 40 patients were restrospectively analysed. 13 out of 40 patients got postoperative radiotherapy. We examined local recurrence, distant metastasis and disease free 5-year survival rate. We also analyzed clinical prognostic factors, such as age, gender, size of tumor, prior unplanned excision, histologic type, surgical excision margin and postoperative radiotherapy respectively. RESULTS: There were 3 cases of local recurrence and 4 cases of distant metastasis. The disease free 5-year survival rate was 85.0%. 26 patients presented with myxoid, 8 well differentiated, 4 round cell, 1 pleomorphic and 1 dedifferentiated histology. The disease free 5-year survival rate of mixoid, well differentiated and round cell liposarcoma were 100.0%, 84.6% and 75.0% (p=0.419). The 5-year disease free survival rate was 90.6% in negative surgical margin (n=25) and 62.5% in positive surgical margin (n=15) (p=0.003). CONCLUSION: Our study suggests that surgical excision margin is significant prognostic factor for 5-year disease free survival rate.

Background: Although the rates of illegal cosmetic procedures performed by beauticians are increasing, there is a dearth of relevant information in the literature regarding these procedures. Objective: This study was aimed to investigate illegal cosmetic procedures that were performed by beauticians with the help of judicial precedents. Methods: The Supreme Court of South Korea’s Written Judgement Management System was searched for judicial precedents regarding illegal cosmetic procedures performed by beauticians. This system included cases that were sentenced in the lower courts, the appellate courts, and the supreme court from the year 1997 to 2019. Results: Twenty-three litigation cases related to these illegal cosmetic procedures were selected. There were 21 criminal cases and two civil cases. Common illegal procedures included tattooing (n=11), use of laser and intense pulsed light device (n=6), administration of intradermal injection (n=3), and application of topical agents (n=2). Two civil cases reported facial deformity and accidental macular damage caused by illegal use of lasers by the beauticians. Conclusion In this study, illegal cosmetic procedures performed by beauticians were identified. Continuous monitoring of these illegal procedures is necessary as they can cause adverse effects in patients.

Background: An evident relationship has been shown between psoriasis and metabolic comorbidities. However, the results in pediatric psoriasis vary from study to study, and no meta-analysis exists on the association of metabolic comorbidities with pediatric psoriasis. Objective: To evaluate the association between psoriasis and metabolic comorbidities in pediatric patients. Methods: We searched articles published in PubMed, EMBASE, and Cochrane Library databases from inception to April 30, 2019. All observational studies reporting the prevalence of obesity or metabolic comorbidities in pediatric patients with psoriasis were included. Results: The meta-analysis included 16 unique studies meeting the inclusion criteria. The pooled odds ratios in pediatric patients with psoriasis was 2.40 (95% confidence interval [CI], 1.60∼3.59) for obesity (13 studies), 2.73 (95% CI, 1.79∼ 4.17) for hypertension (8 studies), 2.01 (95% CI, 1.09∼3.73) for diabetes mellitus (8 studies), 1.67 (95% CI, 1.42∼1.97) for dyslipidemia (7 studies), and 7.49 (95% CI, 1.86∼30.07) for metabolic syndrome (4 studies). Conclusion Pediatric patients with psoriasis showed a significantly higher prevalence of obesity, hypertension, diabetes, dyslipidemia, and metabolic syndrome. Adequate monitoring and timely management of metabolic comorbidities should be considered in these patients.

BACKGROUND: Recent studies have revealed that the splicing factor neuro-oncological ventral antigen 1 (NOVA1) is enriched in fibroblasts and accumulated T cells of tertiary lymphoid structures. In the present study, we investigated NOVA1 expression in various subtypes of mature and immature T- and natural killer (NK)-cell lymphomas as well as in various B-cell lymphoma subtypes. METHODS: NOVA1 immunoexpression was evaluated in hyperplastic palatine tonsils (n = 20), T- and NK-cell lymphomas (n = 177), diffuse large B-cell lymphomas (n = 151), and other types of B cell lymphomas (n = 31). Nuclear staining intensity and percentage of positive tumor cells were graded. NOVA1 mRNA expression was analyzed in various lymphoma cell lines. RESULTS: Tumor cells of T- and NK-cell lymphomas showed higher expression levels of NOVA1 than did normal paracortical T cells, and 56.5% of T- and NK-cell lymphoma cases showed diffuse and strong expression. The NOVA1 expression level varied according to the subtype; it was higher in angioimmunoblastic T-cell lymphoma, anaplastic lymphoma kinase (ALK)-negative anaplastic large cell lymphoma (ALCL), and T lymphoblastic leukemia/lymphoma (T-LBL), but it was lower in ALK-positive ALCL. In almost all B-cell lymphomas, NOVA1 expression was very low or negative. NOVA1 mRNA was also expressed in Jurkat, a T-LBL cell line. CONCLUSIONS: The present findings suggest that NOVA1 upregulation may be involved in certain subtypes of T- and NK-cell lymphomas, but not in B-cell lymphomas. Upregulated NOVA1 expression seems to be a specific biological feature of activated T cells such as T- and NK-cell lymphomas.

BACKGROUND: Progression of coronary artery disease(CAD) is highly unpredictable, and follows a nonlinear course. In previous reports, progression was related to acute myocardial infarction and cardiac death. The present study was designed to assess the characteristics of progression of CAD and to ditermine the predictors for progression. METHODS: The present study included 41 patients(age 55+/-9 years ; male/female=36/5) with CAD who underwent coronary angiography at least twice(interval : mean 26 months), and patients who underwent coronary angioplasty of coronary bypass surgery before the 2nd angiograms were excluded from analysis. The coronary arterial bed was divided into 15 segments according to American Heart Association(AHA) committee report. We measured both % stenosis and minimal diameter of the lesions, and divided the lesions into four Ambrose's morphological categories. Progression was considered to be present if one of the following changes had occurred : increase in % stenosis of lesions by> or =20%, decrease in minimal diameter by> or =0.5mm, or any new occlusion. For the purpose of detecting predictors we investigated clinical history(smoking, hypertension, obesity, and DM), angiographic findings(numbers of diseased vessels and lesions), and biochemical study (total cholesterol, LDL, HDL, triglyceride, uric acid, and albumin). RESULTS: Altogether, 32 patients(78%) showed progression, and regression was present in 11 patients(27%). Six patients had both progressed lesions and regressed lesions. Progression occurred most frequently in segments with stenosis of 1% to 25% at initial arteriogram. Progression occured in increasing order in proximal right coronary artery, mid-LAD, and proximal LAD. There was no significant differences in progression among four Ambrose's morphologic categories. 59(10%) of the analyzable 589 segments had progressed, 19 them upto occlusion, and 7 segments became infarct related artery. In 5(71%) of 7 cases of new myocardial infarction it occurred in segments with< or =75% stenosis at initial arteriogram. The analysis selected two independent predictors for progression: uric acid and numbers of lesions> or =20% stenosis. CONCLUSION: The present study suggests that progression of CAD occurred most frequently in minimally stenotic lesions and that about two thirds of acute myocardial infarction occurred from insignificantly stenotic lesion. Uric acid level and numbers of lesions> or =20% stenosis were selelcted as the independent predictors of coronary disease progression.

There is increasing evidence that genes involved in normal cell growth and differentiation (oncogenes) or genes that encode for growth factors are important in determining the development and biologic aggressiveness of gastric carcinoma. This study was undertaken to define the prognostic value of the overexpression of p53 protein, c-erbB-2 protein, EGFr protein and PCNA in gastric carcinomas. Using monoclonal antibodies, immunohistochemical studies were performed on formalin-fixed, paraffin-embedded tissue sections from 84 primary gastric carcinomas. Overall, 34% of gastric carcinomas had nuclear-staining for p53 protein, 34% of carcinomas membrane staining for the c-erbB-2 and 74% of carcinomas membrane and cytoplasmic staining for EGFr, showing distribution in a heterogeneous fashion. PCNA was expressed as Grade 2 and 3 in 75% of patients with gastric carcinomas. Both c-erbB-2 and p53 staining was significantly associated with high grade expression of PCNA. p53 staining tended to be associated with positive nodal status and metastasis, and c-erbB-2 staining with positive nodal status only. Multivariate analysis using the Cox model showed that overexpression of p53 protein, c-erbB-2 protein and PCNA was not an independent prognostic variable in gastric carcinoma. These results suggest that expressions of p53 and c-erbB-2 protein are heterogeneous and that p53 and c-erbB-2 overexpressions are significantly associated with high proliferative activity in gastric carcinoma.
