BACKGROUND: Aging is a significant issue worldwide, and Korea is one of the most rapidly aging countries. Along with the demographic transition, the age structure of intensive care unit (ICU) patients changes as well. METHODS: The aim of this study was to analyze the change in age distribution of the ICU patients over the last 10 years and its effect on clinical outcomes. Single-center, retrospective analysis of all patients aged ≥18 years admitted to either the medical or surgical ICU at St. Paul's Hospital, The Catholic University of Korea, between January 2005 and December 2014 was conducted. For clinical outcome, in-hospital mortality, duration of ICU stay, and hospital stay were analyzed. Cost analysis was performed to show the economic burden of each age strata. RESULTS: A total of 10,366 ICU patients were admitted to the chosen ICUs during the study period. The proportion of elderly patients aged ≥65 years increased from 47.9% in 2005 to 63.7% in 2014, and the proportion of the very elderly patients aged ≥80 years increased from 12.8% to 20.7%. However, this increased proportion of elderly patients did not lead to increased in-hospital mortality. The percent of ICU treatment days attributable to elderly patients increased from 51.1% in year 2005 to 64.0% in 2014. The elderly ICU patients were associated with higher in-hospital mortality compared to younger age groups. CONCLUSIONS: The proportion of elderly patients admitted to ICUs increased over the last decade. However, overall in-hospital mortality has not increased during the same period.

Takotsubo cardiomyopathy (TTC) is defined as a reversible, acute ventricular dysfunction without any evidence of coronary artery obstruction. There have been reports of TTC caused by emotional or physical stress, drug use, hormone imbalance, or medical conditions such as pulmonary disease, sepsis, and trauma, but a relationship between TTC and pulmonary tuberculosis has not previously been reported. From our knowledge, this is the first report of TTC caused by pulmonary tuberculosis.

PURPOSE: The development of bronchiolitis obliterans syndrome (BOS) after allogeneic hematopoietic stem cell transplantation (HSCT) deteriorates patients' quality of life. This study aimed to analyze the prevalence, clinical features, risk factors and prognostic factors of BOS. MATERIALS AND METHODS: This retrospective study included patients who underwent allogeneic HSCT from January 2002 to December 2008 and survived for > or =100 days after transplantation. RESULTS: Of 860 patients who survived for > or =100 days, 36 (4.2%) met the diagnostic criteria. The duration of BOS development after transplantation was 466.00 (284.00-642.75) [median (interquartile range)] days. The risk factor for the development of BOS was peripheral blood as the stem cell source with a hazard ratio (HR) of 2.550 [95% confidence interval (CI): 1.274-5.104, p=0.008]. In multivariate analysis, pretransplant FEV1/FVC (HR: 0.956, 95% CI: 0.921-0.993, p=0.020) and time from HSCT to diagnosis of BOS (HR: 0.997, 95% CI: 0.994-0.999, p=0.009) were independent prognostic factors associated with mortality. CONCLUSION: Peripheral blood as a stem cell source is a risk factor for the development of BOS. A decreased pretransplant FEV1/FVC and shorter duration of time from transplantation to diagnosis of BOS are poor prognostic factors for BOS.

Biliary drainage in patients with malignant biliary obstruction relieves jaundice and prevents the development of cholangitis or hepatic failure from biliary obstruction. Therefore, this may result in better quality of life along with survival prolongation. Biliary stent placement is an effective and safe measure for biliary decompression and is preferred than bypass surgery in high risk patients. Entero-biliary perforation-communication is one of the rare complications of biliary stent. We herein report a case of duodeno-biliary perforation-communication in patient with distal cholangiocarcinoma who presented with duodenal ulcer and obstruction, occurring 4 years later from the metallic biliary stent insertion. Patient was managed with a pyloric metal stent and conservative care.

Myeloid sarcoma is an uncommon extramedullary tumor of immature myeloid cells or myeloblasts. It may occur alone or concurrently with an underlying hematological malignancy. Although it can develop anywhere in the body, common sites include bones, particularly the skull and vertebra, soft tissues, and lymph nodes. However, there have been few reports of myeloid sarcoma occurring in the respiratory system, especially the large airways. We describe a case of endobronchial relapse of acute myeloid leukemia in a patient who achieved complete remission after allogeneic stem cell transplantation. To our knowledge, this is the first such report in Korea.

Obstructive fibrinous tracheal pseudomembrane (OFTP) is a rare condition usually associated with endotracheal intubation. Airway obstruction caused by OFTP may occur after endotracheal tube extubation and can lead to severe respiratory distress. It is a rare but potentially fatal complication. In this report, we present a case of OFTP presented with atelectasis that caused dyspnea after extubation and was successfully treated by mechanical removal using a rigid bronchoscope.
