This study determines the difference in prevalence of anemia and hemoglobin concentration between chronic obstructive pulmonary disease (COPD) and control groups in the elderly. Moreover, this study also examines the prevalence of anemia and hemoglobin concentration according to the severity of COPD in the elderly. Medical records of 8150 participants who answered the 7th National Health and Nutritional Survey conducted in 2016 were reviewed, and a total of 694 participants was included in the analysis. Participants were classified into two groups: COPD and control groups. Laboratory studies on hemoglobin, hematocrit, red blood cell concentration and prevalence of anemia were collected. Subgroup analysis was also conducted according to the severity of COPD. No significant differences were determined for the prevalence of anemia and hemoglobin concentration between both groups. Hemoglobin concentration was significantly higher in the COPD group. Although not statistically significant, there was a tendency for decrease in the prevalence of anemia and increase in the hemoglobin concentration as the severity of COPD increased. Our findings present specific data about the prevalence of anemia and hemoglobin concentration in elderly patients with COPD. Hence, we propose that occurrence of anemia in elderly patients with COPD requires further evaluation of the causes.

In this study, we developed the severity-adjusted length of stay (LOS) model for acute myocardial infarction patients using data from the hospital discharge survey and proposed management of medical quality and development of policy. The dataset was taken from 2,309 database of the hospital discharge survey from 2004 to 2006. The severity-adjusted LOS model for the acute myocardial infarction (AMI) patients was developed by data mining analysis. From decision making tree model, the main reasons for LOS of AMI patients were CABG and comorbidity. The difference between severity-adjusted LOS from the ensemble model and real LOS was compared and it was confirmed that insurance type and location of hospital were statistically associated with LOS. And to conclude, hospitals should develop the severity-adjusted LOS model for frequent diseases to manage LOS variations efficiently and apply it into the medical information system.

Background : ATS(American Thoracic Society) defined new guidelines for COPD(chronic obstructive lung disease) in April 2001, following the results of the global initiative for chronic obstructive lung disease. The most important concept of COPD is an airflow limitation which is not fully reversible compared to bronchial asthma(BA). The criteria for COPD are postbronchodilator $FEV_1$ less than 80% of the predicted value and an $FEV_1$ per FVC ratio less than 70%. The global initiative for asthma(GINA) study defined asthma, which included immune-mediated chronic airway inflammatory airway disease, and found that airflow limitation was wide spread, variable and often completely reversible. Taken together COPD and BA may be combined in airflow limitation. This study was designed to evaluate the prevalence of BA in patients with COPD of moderate to severe airflow limitation. Methods : COPD was diagnosed by symptoms and spirometry according to ATS guidelines. Enrolled subjects were examined for peak flow meters(PFM), sputum eosinophils and eosinophil cationic protein(ECP) levels, serum total IgE with allergy skin prick test, and methacholine bronchial provocation test(MBPT). Results : About 27% of COPD patients with moderate to severe airflow limitation were combined with BA. There was significantly decreased response to PFM in severe COPD. However, there was no significant relationship between BA and COPD according to the degree of severity. The BA combined with COPD group showed significantly high eosinophil counts and ECP level in induced sputum. However, neutrophil counts in induced sputum showed significant elevation in the pure COPD group. Conclusion : Twenty-seven percent of COPD patients with moderate to severe ventilation disorder were combined with BA, but there were no significant differences according to the degree of severity.

Myasthenia gravis is relatively rare disease which is related autoimmune response. There are various methods of management for myasthenia gravis, but nowaday radical thymectomy is the treatment of choice in the aspect of bringing out complete remission and clinical improvement. Sixteen patients of myasthenia gratis underwent radical thymectomy during last eight years, and its result was analysed. Complete rem ssion was achieved in five patients (31 %) and pharmacological or symptomatic improvement in seven patients (44%), thus giving a total remission in 12 patients (75%). Postoperative result was not correlated with age, sex, degree of preoperative symptom, surgical approach, pathologic diagnosis.

This was a retrospective study that compared the characteristics of patients with decreased mental status (DMS) during their stays in an emergency department (ED) with that of patients with alert mental status (AMS). The participants in this study consisted of 90 patients with DMS who were staying in an ED along with 100 randomly selected patients with AMS. The DMS group contained more instances of cerebrovascular disease, liver disease, diabetes, and hypertension compared to the AMS group (p=0.001, p=0.003, p<0.001, and p=0.002, respectively). With regard to triage, the DMS group had higher severity than the AMS group (p<.001). The final diagnosis for the DMS group was as follows: 64.9% neurological and 63.3% related to the digestive system, which differed from that of the AMS group (p<.001). Fifty-six (62.2%) patients with DMS had their statuses discovered by nurses, while nine patients in the DMS group had received cardiopulmonary resuscitation. These results suggest that ED nurses frequently assess the consciousness of patients who they suspect may have neurologic or digestive diseases and are classified as high severity, even when the patients are alert.

Purpose: The aim of this study was to investigate the current prevalence of protein-energy malnutrition (PEM) and the nutritional status of hospitalized pediatric patients. Methods: We evaluated the nutritional status of the 200 patients from February to July 1994 and the 233 patients from February to July 1999 admitted to Pediatric Department of Chosun University Hospital. Nutritional status was assessed by anthropometric and laboratory data. The nutritional status was classified according to based on the Waterlow criteria and using the laboratory data obtained between 3 days to 5 days after admission. Results: 1) The prevalence of acute PEM (weight for height) was as follows: severe, 0.5%; moderate, 7%; mild, 18%; and none, 74.5% in 1994 and severe, 2.24%; moderate, 3.59%; mild, 19.73%; and none, 74.4% in 1999. 2) The prevalence of chronic PEM (height for age) was as follows: severe, 5%; moderate, 5.5%; mild, 25.5%; and none, 64% in 1994 and severe, 2.24%; moderate, 4.04%; mild, 22.87%; and none, 70.85% in 1999. There was not a statistically significant difference between 1994 and 1999. 3) The prevalence of PEM according to age group, all age group had in general higher prevalence of mild PEM. 4) Values for hemoglobin and albumin were below than total lymphocyte values in PEM. Conclusion: The prevalence of acute or chronic PEM was common in hospitalized children. Therefore, the assessment of nutritional status may an important role to establish effective nutritional support and to improve their subsequent hospital course in hospitalized pediatric patient.

Purpose: We aimed to study the distribution of rotavirus genotypes (VP7 and VP4) and disease severity of rotavirus gastroenteritis prevalent in our community. Methods: Stool samples were collected from 156 children who were hospitalized with rotavirus gastroenteritis from December 2007 to June 2008. The disease severity of all patients was scored using the Vesikari scale. After extraction of ds-RNA of the rotavirus, cDNA synthesis using reverse transcription and polymerase chain reaction (RT-PCR) and multiplex PCR was performed. Following this, the final identification of genotypes was performed. Results: Of the 156 samples, VP7(G) and VP4(P) genotypes were identified in 147 (94.2%) and 140 (89.7%) samples, respectively. G1 (116 of 147 samples; 78.9%) and P[8] (137 of 140 samples; 97.9%) were the most prevalent, respectively. Of the 138 samples identified of combination types of VP7 and VP4, G1P[8] (111 samples; 80.4%) was the most prevalent. Other combination types varied with very low distribution rates. 9.4% of genotypes were not included in the new vaccines. The disease severity score was $11.8{\pm}3.3$ ($mean{\pm}2SD$). The distribution of disease severity was mild or moderate in 37.8% and severe in 62.2% of patients. Conclusion: The most prevalent genotype combination of rotavirus was G1P[8] and genotypes not included in the vaccines represented 9.4% in our community. Disease severity distribution of hospitalized children with rotavirus gastroenteritis was higher in the severe than in the mild and moderate categories.
