We have reviewed 1211 burn patients who had visited our emergency department of Keimyung University Dongsan medical center between April 1995 to March 1997. The following results were obtained; 1) On age and sex distribution, the highest incidence of age group was under 10 year and old in 321 cases(26.5%). Male was affected more frequently than female, the incidence being 847 cases(70.1%) and 364 cases(29.9%). The ratio of male to female was 2.3:1. 2) No monthly and seasonal differences could be recognized. We found winter season having the highest 319 cases(26.3%), followed by autumn, spring and summer. 3) An analysis of causes in burns showed that flame burns were 527 cases(43.1%), scalding burns, 486 cases(40.2%), electrical burns, 96 cases(8.1%) and chemical burns, 48 cases(4.1%). 4) Domestic accidents accounted for 639 cases(52.7%), occupational for 286 cases(23.6%), traffic accidents for 160 cases(13.2%), suicides for 122 cases(10.1%), formentation for 4 cases(0.4%). 5) Most of patients 699 cases(57.7%) were affected with 2nd degree burn in depth, 1st degree for 413 cases(34.1%) and 3rd degree for 99 cases(8.2%). 6) The trunk was the anatomical region most commonly affected followed by upper and lower limbs. 7) 243 cases(20.5%) of all were accompanied by some complications. The main complications were would infection noted in 212 cases(17.5%), pneumonia in 179 cases(14.8%), acute renal failure in 160 cases(13.2), contracture in 155 cases(13.0), urinary tract infection in 24 cases(2.0%), Curling ulcer in 20 cases(1.6%) in order. 8) The over-all mortality rate was 73 cases(6.1%).

This study was designed retrospectively to evaluate Ranson's criteria and APACHE II scores as a predictor of mortality in patients with acute pancreatitis. Acute pancreatitis is a common disorder. From mild disease to multiorgan failure, it is a disorder that has numerous causes, an obscure pathogenesis. An accurate history and through physical examination will often raise clinical suspicion of acute pancreatitis in the differential diagnosis of a patient with acute abdominal pain. The retrospective analysis by chart review of 86 cases of acute pancreatitis who visited emergency department of Dongsan hospital from Jan to Dec 1996. The results were as follows. The majority of the patients with acute pancreatitis presented with chief complaints of abdominal pain. The male patient outnumbered female by the ratio of 2.9:1. The highest incidence of age group was between 40 and 50. The majority of our patients had past histories of either chronic alcoholic or gallbladder problems e.g.. the number being 53 cases(61.6%) and 31 cases(36%) respectively. Among 7 patients who had changes in consciousness, 5 were expired. Of those expired, 3 patients had less than 90 mmHg of systolic blood pressure. The overall mortality rate was 10.5%(9 cases). It has been known that acute pancreatitis would be the results of traumatic and non-traumatic causes. The exact mechanism of its pathophysiolgy has not been known yet, but it has been well known that the majority of patients who in forties and fifties had history of alcoholic abuse, the rest being mainly gallbladder problem and, some other diseases implicated too. The relationship of acute pancreatitis with familiar Ranson's criteria was such that 3 patients of the Ranson's out of 9 death were noted to have more than 3 of the criteria, but another 3 had less than 3. Among the 60 patients in whom the required physiologic variables were available out of total 86 patients studied, 9 were expired and 51 survived, average APACHE II scores for the survival and the expired being 6.92+/-3.99 & 18.11+/-5.68 respectively (P<0.05). We concluded that the APACHE II score could be used to better than Ranson's criteria to predict hospital mortality in patients with acute pancreatitis.

It has been reported that fatty acid binding proteins (FABPs) do not act only as intracellular mediators of lipid responses but also have extracellular functions. This study aimed to investigate whether extracellular liver type (L)-FABP has a biological activity and to determined serum L-FABP levels in patients with end-stage renal disease (ESRD). We isolated L-FABP complementary deoxyribonucleic acid (cDNA) from the Huh7 human hepatocarcinoma cell line and expressed the recombinant L-FABP protein in Escherichia coli. A549 lung carcinoma and THP-1 monocytic cells were stimulated with the human recombinant L-FABP. Human whole blood cells were also treated with the human recombinant L-FABP or interleukin (IL)-1α. IL-6 levels were measured in cell culture supernatants using IL-6 enzyme-linked immunosorbent assay (ELISA). Human recombinant L-FABP induced IL-6 in a dose-dependent manner in A549, THP-1 cells, and whole blood cells. The blood samples of healthy volunteers and patients with ESRD were taken after an overnight fast. The serum levels of L-FABP in healthy volunteers and ESRD patients were quantified with L-FABP ELISA. The values of L-FABP in patients with ESRD were significantly lower than those in the control group. Our results demonstrated the biological activity of L-FABP in human cells suggesting L-FABP can be a mediator of inflammation.

Interferons (IFNs) have been known as antiviral genes and they are classified by type 1, type 2, and type 3 IFN. The type 1 IFN consists of IFNα, IFNβ, IFNτ, and IFNω whereas the type 2 IFN consists of only IFNγ, which is a key cytokine driving T helper cell type 1 immunity. IFNλ belongs to the type 3 IFN, which is also known as IL-28 and IL-29 possessing antiviral activities. Type 1 IFN is produced by viral infection whereas type 2 IFN is induced by mitogenic or antigenic T-cell stimuli. The IFNτ of bovine was first discovered in an ungulate ruminant recognition hormone. IFNτ belongs to the type 1 IFN with the common feature of type 1 IFN such as antiviral activity. IFNs have been mostly studied for basic research and clinical usages therefore there was no effort to investigate IFNs in industrial animals. Here we cloned porcine IFNα8 from peripheral blood mononuclear cells of Korean domestic pig (Sus scrofa domestica). The newly cloned IFNα8 amino acid sequence from Korean domestic pig shares 98.4% identity with the known porcine IFNα8 in databank. The recombinant porcine IFNα8 showed potent antiviral activity and protected bovine Madin-Darby bovine kidney epithelial (MDBK) cells from the cytopathic effect of vesicular stomatitis virus, but it failed to protect human Wistar Institute Susan Hayflick (WISH) cells and canine Madin-Darby canine kidney epithelial-like (MDCK) cells. The present study demonstrates species specific antiviral activity of porcine IFNα8.

A febrile respiratory infectious disease unit (FRIDU) with a negative pressure ventilation system was constructed outside the emergency department (ED) of the Samsung Medical Center in 2015, to screen for patients with contagious diseases requiring isolation. We evaluated the utility of the FRIDU during 1 year of operation. We analyzed 1,562 patients who were hospitalized after FRIDU screening between August 2015 and July 2016. The level of isolation recommended during their screening at the FRIDU was compared with the level deemed appropriate given their final diagnosis. Of the 1,562 patients screened at the FRIDU, 198 (13%) were isolated, 194 (12%) were reverse isolated, and 1,170 (75%) were not isolated. While hospitalized, 97 patients (6%) were confirmed to have a contagious disease requiring isolation, such as tuberculosis; 207 patients (13%) were confirmed to be immunocompromised and to require reverse isolation, mainly due to neutropenia; and the remaining 1,258 patients (81%) did not require isolation. The correlation coefficient for isolation consistency was 0.565 (P < 0.001). The sensitivity and negative predictive value of FRIDU screening for diagnosing contagious disease requiring isolation are 76% and 98%, respectively. No serious nosocomial outbreaks of contagious diseases occurred. During FRIDU screening, 114 patients were admitted to the resuscitation zone due to clinical instability, and three of these patients died. The initial isolation levels resulting from FRIDU screening were moderately well correlated with the isolation levels required by the final diagnosis, demonstrating the utility of pre-hospitalization screening units. However, the risks of deterioration during the screening process remain challenges.

BACKGROUND: The burden of nontuberculous mycobacterial (NTM) pulmonary disease (PD) is increasing globally. To understand the treatment outcomes and prognosis of NTM-PD, a unified registry is needed. In this project, we aim to construct a multicenter prospective observational cohort with NTM-PD in South Korea (NTM-KOREA). METHODS: The primary objective of this study is to analyze treatment outcomes according to the species. In addition, recurrence rate, adverse events, the impact of each drug on treatment outcomes as well as the impact of characteristics of mycobacteriology will be analyzed. The inclusion criteria for the study are as follows: fulfilling the criteria for NTM-PD having one of the following etiologic organisms: Mycobacterium avium complex, M. abscessus subspecies abscessus, M. abscessus subspecies massiliense, or M. kansasii; receiving the first treatment for NTM-PD after enrollment; age >20 years; and consenting to participate in the study. Seven institutions will participate in patient enrollment and about 500 patients are expected to be enrolled. Participants will be recruited from 1 March 2020 until 19 March 2024 and will be observed through 19 March 2029. During the follow-up period, participants' clinical course will be tracked and their clinical data as well as NTM isolates will be collected. CONCLUSION NTM-KOREA will be the first nationwide observational cohort for NTM-PD in South Korea. It will provide the information to optimize treatment modalities and will contribute to deeper understanding of the treatment outcomes and long-term prognosis of patients with NTM-PD in South Korea.

Background: Because the etiologies of bronchiectasis and related diseases vary significantly among different regions and ethnicities, this study aimed to develop a diagnostic bundle for bronchiectasis in South Korea. Methods: A modified Delphi method was used to develop expert consensus statements on a diagnostic bundle for bronchiectasis in South Korea. Initial statements proposed by a core panel, based on international bronchiectasis guidelines, were discussed in an online meeting and two email surveys by a panel of experts (≥70% agreement). Results: The study involved 21 expert participants, and 30 statements regarding a diagnostic bundle for bronchiectasis were classified as recommended, conditional, or not recommended. The consensus statements of the expert panel were as follows: A standardized diagnostic bundle is useful in clinical practice; diagnostic tests for specific diseases, including immunodeficiency and allergic bronchopulmonary aspergillosis, are necessary when clinically suspected; initial diagnostic tests, including sputum microbiology and spirometry, are essential in all patients with bronchiectasis, and patients suspected with rare causes such as primary ciliary dyskinesia should be referred to specialized centers. Conclusion Based on this Delphi survey, expert consensus statements were generated including specific diagnostic, laboratory, microbiological, and pulmonary function tests required to manage patients with bronchiectasis in South Korea.
