We have experienced 66 cases of video assisted thoracic surgery(VATS) of spontaneous pneumothorax. The patients ranged in age from 15years to 46years(mean age, 22.3years) and male patients were sixty three. The indications of video assisted thoracic surgery of spontaneous pneumothorax were recurrence, continuous air leakage, visible blebs on the chest X-ray and others. Infraoperative findings were as follows; blebs, pleural adhesion and pleural effusion. The operation was performed under general anesthesia with double lumen endo- bronchial tube. Operative procedures included blebectomy and/or wedge resection of lung, vibramycin pleurodesis with mechanical abrasion. In most cases, postoperative courses were uneventful and patients were discharged without significant complications. VATS provided the benefits of lesser postoperative pain, rapid recovery, short hospitalization, and smaller scar of wound. Conclusively VATS is a new interesting modality of surgical treatment of spontaneous pneumothorax and also can be extensively applicable in the diagnosis and treatment of other intrathoracic disease.

PURPOSE: To present and evaluate a system of high-frequency oscillatory ventilator (HFOV) during intra-/inter-hospital neonate transport. METHODS: The system includes a charged HFOV (SOPHIE, Fritz Stephan GmbH, Dusseldorf, Germany), an incubator, and E-oxygen/air-cylinders with connections to the HFOV. The test lung was evaluated at the high and medium ventilator settings used for infants to determine the operating time of HFOV. The time required to exhaust the gas supply was checked, and the HFOV was operated until the low-battery alarm sounded to determine the operating time of the batteries. RESULTS: The batteries provided electrical power for at least 60 mins, and the oxygen and air-cylinders lasted at least 20 mins. The system has been used frequently for the intra-hospital transport, from delivery rooms to ICU and from ICU for surgery. The system has been used twice for the inter-hospital transport of infants with bronchopulmonary dysplasia and pulmonary hypertension to another hospital 45 km away (one hour distance). In one case, the ambulance's electrical power supply failed, causing the system failure during the last 5 mins of transport. However, with the complete check and simulation of the system and the ambulance bulk oxygen/electric supply, the second patient was transported successfully in stable condition. CONCLUSION: The system was useful for intra-/inter-hospital transport of the neonates on HFOV. For the transport time of 60 mins, fully charged HFOV, 2 E-oxygen-cylinders, and 3 E-air-cylinders seemed to be sufficient. H-oxygen-cylinder and ambulance electrical power supply should also be provided for safe and efficient transport between hospitals.

We report two cases of toxic methemoglobinemia caused by an inert ingredient in pesticide product after intentional ingestion of pesticide. First, 51-year-old male visited to the emergency department (ED) after the ingestion of pesticide in a suicide attempt. Initial methemoglobin (MetHb) level was 25.6%. We did not know the cause of methemoglobinemia at that time. Second, 56-year-old female visited to the ED after the ingestion of the same pesticide in a suicide attempt. MetHb level after 30 minutes was 16.1%. The patients were treated with methylene blue. We contacted to the Korean Rural Development Administration and estimated that magnesium nitrate was more likely to cause methemoglobinemia. This report highlights the importance of considering the possibility of methemoglobinemia caused by inert ingredient in pesticide and early antidotal therapy.

The prevalence of multiple job-holding (MJH) is expected to show an upward trend among Korean workers, yet its potential impact on workers’ health remains poorly discussed. This study aimed to explore the association between MJH and experience of physical and psychological symptoms in various aspects among active Korean workers and to identify its differences depending on workers’ gender.

The coronavirus disease 2019 (COVID-19) pandemic drastically modified the occupational system wherein telecommuting has risen as the major form of work. Few studies have incorporated Karasek’s job demand-control (JDC) model into explaining the health effects of telecommuting. This study aimed to investigate the health risk in South Korean telecommuters during the pandemic, and its distribution according to the job stress-related factors.
