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.

BACKGROUND: Recently, the use of ultrasound (US) techniques in regional anesthesia and pain medicine has increased significantly. However, the current extent of training in the use of US-guided pain management procedures in Korea remains unknown. The purpose of the present study was to assess the current state of US training provided during Korean Pain Society (KPS) pain fellowship programs through the comparative analysis between training hospitals. METHODS: We conducted an anonymous survey of 51 pain physicians who had completed KPS fellowships in 2017. Items pertained to current US practices and education, as well as the types of techniques and amount of experience with US-guided pain management procedures. Responses were compared based on the tier of the training hospital. RESULTS: Among the 51 respondents, 14 received training at first- and second-tier hospitals (Group A), while 37 received training at third-tier hospitals (Group B). The mean total duration of pain training during the 1-year fellowship was 7.4 months in Group A and 8.4 months in Group B. Our analysis revealed that 36% and 40% of respondents in Groups A and B received dedicated US training, respectively. Most respondents underwent US training in patient-care settings under the supervision of attending physicians. Cervical root, stellate ganglion, piriformis, and lumbar plexus blocks were more commonly performed by Group B than by Group A (P < 0.05). CONCLUSIONS: Instruction regarding US-guided pain management interventions varied among fellowship training hospitals, highlighting the need for the development of educational standards that mandate a minimum number of US-guided nerve blocks or injections during fellowships in interventional pain management.

PURPOSE: To compare surgically induced astigmatism (SIA) and some corneal higher order aberrations in patients who underwent microcoaxial cataract surgery (MCCS) or conventional cataract surgery. METHODS: A prospective randomized study included 60 eyes of 55 patients. Thirty eyes received MCCS using a 2.2mm clear corneal incision (group 1), and 30 eyes received conventional cataract surgery using a 2.8 mm clear corneal incision (group 2). SIA and corneal higher order aberrations were measured with a Keratometer (Humphrey, Zeiss) and i-Trace (Tracey Technologies) preoperatively, and at 1 and 3 months after cataract surgery. SIA was analyzed vectorially using the Alpins method. RESULTS: There was no significant difference in preoperative UCVA or BCVA between the two groups. At 1 month and 3 months after surgery, SIA in group 1 was less than that in group 2, but this difference was not significant. There was no statistically significant difference in postoperative change of corneal higher order aberrations in each group at 1 month or 3 months after surgery, and there was no statistically significant difference in corneal higher order aberrations between the two groups preoperatively, at 1 month, or 3 months after surgery. CONCLUSIONS: There was no significant difference in SIA and corneal higher order aberrations between the two groups.

It is well known that drinking and smoking have great influence on the survival rate of patients of squamous cell carcinoma of tongue. But these was no statistical significance.CONCLUSION: The overall 5-year survival rate of tongue cancer was 67.0% and it was mostly influenced by factors like age, pTNM stage, cervical lymph node metastasis, differentiation of cancer cell etc.]]>

The arteriovenous malformation(AVM) of the gastrointestinal tract is a rare cause of gastrointestinal bleeding. With the increasing use of angiography over the past 30 years in the assessment of gastrointestinal bleeding, AVM has been more frequently recognized. There are few reports, however, about the arteriovenous malformation of stomach. From 1884, about 40 cases were reported all over the world. The clinical manifestation of gastric AVM are asymptomatic massive upper gastrointestinal bleeding or chronic iron deficiency anemia, The diagnosis of gastric AVM is difficult because of nonspecific findings using an endoscopy. This lesion is easily detected using a selective angiography. Furthermore, the therapeutic embolization of the feeding artery have a better chance for stopping the bleeding. In this paper we are reporting one case of gastric AV malformation, wherein rnassive UGI bleeding and dingnosis was made usmg a selective angiography. A review of literatmes was conducted to make this report possible.
