Background and Objectives: Understanding the trends in cardiovascular disease (CVD) mortality is important for developing burden reduction strategies. Based on the Cause of Death Statistics, we examined the changing patterns of CVD mortality in Korea between 1983 and 2018. Methods: Causes of death were coded according to the International Classification of Disease, 10th revision. Deaths from all diseases of circulatory system (I00-I99) and the following 6 subcategories were analyzed: total heart diseases (I00-I13 and I20-I51), hypertensive heart diseases (I10-I13), ischemic heart diseases (I20-I25), myocardial infarction (I21-I23), heart failure (I50), and cerebrovascular diseases (I60-I69). Crude, age-standardized, and age-stratified rates were calculated to assess temporal trends in CVD mortality. Results: The number of deaths and crude mortality rate for all diseases of circulatory system increased recently mainly due to the population ageing. Specifically, total heart diseases showed increasing trend, whereas cerebrovascular diseases showed decreasing trend. Between 1983 and 2018, age-standardized mortality rates significantly declined for all diseases of circulatory system, total heart diseases, hypertensive heart diseases, and cerebrovascular diseases. Age-standardized mortality rates for ischemic heart diseases and myocardial infarction peaked in the early 2000s then decreased thereafter. However, agestandardized mortality rate for heart failure rapidly increased, especially in recent years. Conclusions CVD mortality in Korea has remarkably decreased over the last 36 years.However, the recent rise in the absolute number of deaths from heart diseases, especially from heart failure, calls for attention in prevention and management of CVD and its sequelae.

Purpose: Glabridin (GD) is a bio-available isoflavane isolated from the root extract of licorice (Glycyrrhiza glabra L.). It exhibits a variety of pharmacological activities such as antiinflammatory and anti-oxidant activities. However, extracellular vesicles (EVs) secretion and the anti-cancer mechanism of action remains largely unknown. The present study investigates the anticancer effects of GD by determining the inhibition of EVs secretion in the human breast cancer cell line, MDA-MB-231. Methods: Cell viability, reactive oxygen species (ROS) production, migration, invasion rate, and vascular endothelial growth factor (VEGF) concentration were assessed in MDA-MB-231 cells treated with increasing concentrations of GD (0.1, 1, 5, 10, 20 μM). Subsequently, EV secretion and exosomal DEL-1 protein expression were evaluated to determine the anticancer effects of GD. Results: The results showed that GD significantly inhibited the cell proliferation of MDAMB-231 cells in a dose- or time-dependent manner. Also, ROS production and apoptosis marker protein cleaved caspase-3 were significantly increased in GD-treated MDA-MB-231, compared to control. Furthermore, GD exposure resulted in significantly decreased not only migration and invasion rates but also the VEGF concentration, thereby contributing to a reduction in angiogenesis. Interestingly, the concentration and number of EVs as well as EV marker proteins, such as CD63 and TSG101, were decreased in GD-treated MDA-MB-231 cells. Markedly, extracellular matrix protein DEL-1 as angiogenesis factor was decreased in EVs from GD-treated MDA-MB-231 cells. Conclusion This study identifies that the anti-cancer molecular mechanism of GD is exerted via inhibition of angiogenesis and EVs secretion, indicating the potential of GD as a chemotherapeutic agent for breast cancer.

Hepatic portal venous gas (HPVG) has been considered a rare entity associated with a poor prognosis. Portal vein gas is most commonly caused by mesenteric ischemia but may have a variety other causes. HPVG can be associated with ischemic bowel disease, inflammatory bowel disease, intra-abdominal abscess, small bowel obstruction, acute pancreatitis, and gastric ulcer. Because of high mortality rate, most HPVG requires emergent surgical interventions and intensive medical management. We experienced a case of hepatic portal venous gas caused by acute pancreatitis and successfully treated with medical management.

PURPOSE: Nonallergenic irritants can aggravate the symptoms of rhinitis. We investigated the clinical responses of children with allergic rhinitis (AR) and nonallergic rhinitis (NAR) to nonallergenic irritants, and identified factors associated with these responses. METHODS: Children with chronic rhinitis (n=208) were classified as having AR or NAR based on the presence of aeroallergen-specific IgE. Healthy controls (n=24) were recruited for comparison. The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines were used to classify patients, and their irritant score (0-21 points) and current symptom score (5-35 points) were measured. Subjects with irritant scores ≥3 and <3 were classified as having irritant and nonirritant rhinitis, respectively. RESULTS: The mean age of enrolled subjects was 6.8 years (range: 1.8-16.0 years). The AR and NAR groups had similar irritant scores (P=0.394) and proportions of subjects with irritant scores ≥3 (P=0.105). Irritant score correlated positively with symptom score (P=0.005), and the proportion of subjects with irritant scores ≥3 was greater in children with moderate-severe rhinitis than in those with mild rhinitis (P=0.046). Multiple logistic regression analysis indicated that the presence of atopic eczema increased the risk for sensitivity to a nonallergenic irritant (aOR=2.928, 95% CI 1.567-5.473, P=0.001). CONCLUSIONS: Response to a nonallergenic irritant was useful for gauging the severity of rhinitis, but not for differentiating AR from NAR. AR and NAR patients with atopic eczema may increase nasal sensitivity to nonallergenic irritants.

PURPOSE: Fractional exhaled nitric oxide (FeNO) is a maker of airway inflammation, and impedance of low frequency in the impulse oscillometry system (IOS) reflects small-airway obstruction. We investigated the association of the FeNO level with IOS parameters and spirometry results in asthma patients. METHODS: Fifty-eight children with asthma (60.3%, male), mean age 8.3 years (range, 4.5-16.0 years), were enrolled in the study. Reactance and resistance at 5 Hz with IOS, forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and forced expiratory flow 25%-75% of the vital capacity (FEF25%-75%) with spirometry and FeNO were measured in all patients. The Z-score of spirometry and IOS parameters and the mean level of FeNO were used for correlation and regression analysis. RESULTS: FeNO was not significantly associated with height, age, or other demographic parameters. There was a statistically significant correlation between spirometry results and IOS measurements. The FeNO level was not significantly correlated with IOS variables. After adjusting for height, sex, atopic status, and the use of inhaled corticosteroid, the FeNO level showed significant correlations with Z-score of FEV1/FVC (P=0.037, adjusted R 2=0.234). CONCLUSION: FeNO was significantly correlated with Z-scores of FEV1/FVC, but not with IOS variables. Therefore, FeNO may be used to detect whole airway obstruction, but not small-airway obstruction.

Osteochondroma is a common bone tumor but a rare tumor in the rib. It is often asymptomatic and observed incidentally. This is a case report of a 49-year-old woman with an osteochondroma mimicking a mediastinal mass in hereditary multiple exostoses. The chest X-ray and computed tomography (CT) scans revealed the bony density feature of the mass. Surgical excision confirmed that the lesion was an osteochondroma.

BACKGROUND: We had undergone this study to investigate clinical progress of this disease and to decide the role of aggressive diagnostic approaches, the efficacy of treatments and prognoses. METHODS: A retrospective study was done on 113 patients who had been diagnosed to metastatic adenocarcinoma of pleura by pleural fluid cytology (106 cases) or pleural needle biopsy(22 cases), at Presbyterian Medical Center, from Jan. 1990 to Dec. 1994. RESULTS: 1) The patients were composed of 59 males(52.2%) and 54 females(47.8%), and the mean age distribution was 57.4 +/- 12.1 years. 2) The site of origin was lung cancer 46.9%(53/l 13), stomach cancer 20.4%(23/113), breast cancer 11.5%(13/113), and unknown primary site 6.2%(7/113 cases), as a whole. In male, lung cancer was 55.9%(33/59), stomach cancer was 28.8%(17/59), and in female, lung cancer was 37% (20/54), breast cancer was 24.1% (13/54) of cases. 3) The cardinal symptoms were dyspnea(69%), cough(61%), chest pain(50%), weight loss(50%), anorexia(49%), sputum(43%), malaise(30%). 4) The pleural fluid findings were exudative in 94.4%(102/108), serosanguinous or bloody in 36~53%, unilateral involvement in 74.3%(84/l 13) of cases, and lymphocyte predominance (71 +/- 27%) in differential count of WBC. 5) CEA levels in pleural fluid or plasma were over 10ng/ml in 60.6% (40/66), and ADA levels in pleural fluid were under 40U/L in 95% (57/60) of cases. 6) The patients were managed by various methods, but the efficacy of treatment was uncertain. 7) The mean survival time was 12.7 +/- 13.5 weeks. CONCLUSION: It seems to be no effective treatment methods yet and the prognosis was very poor in this disease, so the objectives of diagnostic approaches and treatment methods should be directed to early diagnosis, treatment and prevention of curable disease. And we must make our best endeavors to lengthen the survival time and improve the quality of patients' life.

Behcet's disease (BD) is a multi-systemic inflammatory disease of unknown origin that affects nearly all organs. Recent reports of BD with myelodysplastic syndrome (MDS) often note an association with gastrointestinal involvement and trisomy 8. We herein report on a case of a 51-year-old man who had refractory schizophrenia and developed gastrointestinal BD and MDS with trisomy 8 and 9. He visited our hospital due to fever and abdominal pain. Multiple ulcerations in the colorectum were observed on colonoscopy, and he was diagnosed with intestinal BD. During the treatment of intestinal BD, anemia and thrombocytopenia developed. His bone marrow study revealed myelodysplastic syndrome (refractory anemia with ringed sideroblast) with trisomy 8 and trisomy 9. We report a rare case of intestinal BD accompanied by schizophrenia and myelodysplastic syndrome with trisomy 8 and 9.
