In the spring of 2011, a cluster of lung injuries caused by humidifier disinfectant (HD) usage were reported in Korea. Many patients required mechanical ventilation, extracorporeal membrane oxygenation, and even lung transplantation (LTPL). However, the long-term course of HD-associated lung injury remains unclear because the majority of survivors recovered normal lung function. Here we report a 33-year-old woman who underwent LTPL approximately four years after severe HD-associated lung injury. The patient was initially admitted to the intensive care unit and was supported by a high-flow nasal cannula. Although she had been discharged, she was recurrently admitted to our hospital due to progressive lung fibrosis and a persistent decline in lung function. Finally, sequential double LTPL was successfully performed, and the patient's clinical and radiological findings showed significant improvement. Therefore, we conclude that LTPL can be a therapeutic option for patients with chronic inhalation injury.

Anomalous right coronary artery arising from the left sinus of Valsalva is rare, but not protected from ather-osclerotic disease. Major factor determining successful angioplasty is the selection of the appropriate guiding catheter to provide optimal coaxial backup support. We report the first case of successful transradial stenting of an anomalous right coronary artery originating from the left sinus of Valsalva.

Severe acute respiratory distress syndrome (ARDS) is a life-threatening disease with a high mortality rate. Although many therapeutic trials have been performed for improving the mortality of severe ARDS, limited strategies have demonstrated better outcomes. Recently, advanced rescue therapies such as extracorporeal membrane oxygenation (ECMO) made it possible to consider lung transplantation (LTPL) in patients with ARDS, but data is insufficient. We report a 62-year-old man who underwent LTPL due to ARDS with no underlying lung disease. He was admitted to the hospital due to influenza A pneumonia-induced ARDS. Although he was supported by ECMO, he progressively deteriorated. We judged that his lungs were irreversibly damaged and decided he needed to undergo LTPL. Finally, bilateral sequential double-lung transplantation was successfully performed. He has since been alive for three years. Conclusively, we demonstrate that LTPL can be a therapeutic option in patients with severe ARDS refractory to conventional therapies.

PURPOSE: The aims investigated how how human osteosarcoma cell proliferation and the MAP kinases cascade are regulated, in the MG63 and U2OS human osteosarcoma cell lines after stimulating them with adrenomedullin (AM) with particular focus on extracellular signal-regulated kinase 1/2 (ERK 1 and 2) activation. MATERIALS AND METHODS: A cell proliferation assay was used to examined the effects of AM on the osteosarcoma cell lines (MG63 and U2OS). The effects of AM on ERK1/2 were examed by Western blot analysis. The roles of ERK 1/2 in the AM-induced proliferative signaling pathways in the two cell types were examed using PD98059, a selective inhibitor of the mitogen activated protein-ERK kinase (MEK) pathway. RESULTS: The addition of AM to the medium containing the osteosarcoma MG63 and U2OS cells induced proliferation in a dose-dependent manner. AM strongly activated ERK 1/2 mediated cell proliferation signaling, which was prevented using PD98059. CONCLUSION: These results suggest that AM plays an important role in the proliferation of human osteosarcoma MG63 and U2OS cells, and ERK kinase pathway plays a signal transduction role in AM treated human osteosarcoma MG63 and U2OS cell lines.

Purpose:
The cephalic arch is a significant site of stenosis in proximal arteriovenous fistulas (AVFs) that contributes to access dysfunction and thrombosis. This study aimed to evaluate the outcomes of surgical treatment (ST) and endovascular treatment (ET) for cephalic arch stenosis (CAS).
Materials and Methods:
A total of 62 patients with proximal AVF who underwent CAS revision using either ST or ET were enrolled between January 2018 and March 2023. In the ET group, only the initial ET following AVF formation was considered, to mitigate bias. In the ST group, central transposition of the native AVF (transposition group) or interposition of the prosthetic graft into the proximal basilic or axillary vein (interposition group) was performed. We evaluated primary and functional patency based on these groups and calculated the number of patency loss events after CAS treatment.
Results:
Of the 62 patients, 38 (61%) were male, with a mean age of 66.4 years. ST was performed in 26 (42%) patients, including transposition in 16 and interposition in 10, whereas ET was administered to 36 patients during the study period.Among the ST recipients, 42% had a history of ET for CAS. The incidence of AVF thrombosis was marginally higher in the ST group than in the ET group (39% vs.19%, P=0.098). The primary patency rates at 6 months, 1 year, and 3 years were 87%, 87%, and 66% in the transposition group; 45%, 23%, and 11% in the interposition group; and 66%, 49%, and 17% in the ET group, respectively. Notably, the primary patency of the transposition group was significantly higher than that of the interposition (P=0.001) and ET groups (P=0.016). The frequency of patency loss events per person-year after the initial revision was 0.40, 0.52, and 1.42 in the transposition, interposition, and ET groups, respectively.
Conclusion
Transposition exhibited the most favorable primary patency rate and the lowest number of subsequent patency loss events during follow-up despite the higher rates of AVF thrombosis and previous ET at presentation. Consequently, transposition should be actively considered in eligible patients with CAS.

An 84-year-old woman presented with obstructive jaundice due to unresectable gallbladder cancer with a left renal cell carcinoma. Endoscopic retrograde cholangiopancreatography (ERCP) and percutaneous transhepatic biliary drainage (PTBD) were unsuccessful because of tumor obstruction of the duodenal bulb, right hepatic duct and distal common bile duct. Endoscopic ultrasound (EUS)-guided biliary drainage with a transgastric approach was performed. A guide-wire was passed through the biliary obstruction and was successfully advanced into the duodenum via the ampulla. The procedure was completed in an antegrade fashion. The obstructed biliary system was successfully decompressed by the insertion of a biliary covered metal stent through the malignant stricture. There were no complications related to the use of this procedure.

Adrenal cyst is a rare disease and its incidence rate is about 0.06~0.18%. Many cases of adrenal cysts are diagnosed incidentally. Surgical excision is generally performed to rule out malignancy when an adrenal cyst is detected. However, a reviewing the overall cases revealed that only 7% of adrenal cysts were malignant or potentially malignant. Thus, it has been suggested to observe an asymptomatic simple benign cyst after aspiration. From this point of view, it is necessary to perform a functional hormonal test and fine needle aspiration cytology for investigating the nature of adrenal cysts. Adrenal cyst drainage can be performed when surgical resection is not indicated. Computed tomography or ultrasonography guided percutaneous aspiration and drainage has been performed, but linear endoscopic ultrasound has not yet been used for this purpose. We have performed endoscopic ultrasound guided fine needle aspiration of adrenal cysts for cytologic and hormonal examination and endoscopic ultrasound guided adrenal cyst drainage, and we report here on our experiences with this technique.

BACKGROUND/AIMS: Acute lower gastrointestinal bleeding (LGIB) is a common disorder that requires hospitalization. Colonoscopy is considered as the procedure of choice for diagnosing acute LGIB. The aim of this study was to analyze the clinical characteristics, endoscopic diagnosis and clinical course of acute LGIB. METHODS: From January 2000 to August 2007, 117 patients with hematochezia, who visited Yeungnam University hospital emergency center and underwent colonoscopy or sigmoidoscopy, were reviewed retrospectively. The male to female ratio was 2.25 (81:36). The mean age was 59.1+/-16.9 years. RESULTS: The mean time from presentation to endoscopy was 12.6 hours. The cause of bleeding was identified in 88.9% of the cases after endoscopy. The causes of the acute LGIB were colitis: 26 cases, post polypectomy bleeding: 17 cases, colon ulcer: 16 cases, diverticular bleeding: 13 cases, colon cancer: 9 cases, angiodysplasia: 7 cases and hemorrhoid: 6 cases. Thirty six patients were treated by the endoscopic method; the mean duration of admission was 10.6+/-10.0 days and the mean amount of transfusion was 3.0+/-1.9 U. Those numbers showed statistically significant differences according to the diagnosis. CONCLUSIONS: The most common cause of acute LGIB was colitis and the causes of bleeding were a significant factor that affects the severity of bleeding and the duration of admission.
