Herpes simplex virus [HSV] esophagitis is a rare disease and most of cases are reported in the immunocompromised patients. We report a case of fatal HSV infection started from herpes labialis and esophagitis. She had initially suffered from perioral ulcer, esophagitis, and interstitial pneumonitis later and eventually died of respiratory insufficiency one month later after the aneurysmal surgery. She did not have any immunocompromised medical history and also had no evidence of herpes encephalitis in laboratory study and magnetic resonance image [MRI]. With the availability of effective agents for the treatment of HSV infection, early recognition of HSV esophagitis is important because it may be clinically confused with Cushing ulcer and may be complicated with a fatal pneumonitis.

As the size of construction projects has become larger in recent years, the nature of the disaster safety factors along with the progress of construction is also becoming more complex and diversified. Accordingly, the introduction of computerized construction, new technologies, and new construction methods has resulted in a variety of risk factors in the process and operations, and many new safety construction methods are being tried. Since the construction industry has variable working environments and constantly changes working methods and components depending on the rate of progress, workers at construction sites are always exposed to risk depending on the specific circumstances of the construction industry. This study attempts to collect and analyze major accident cases generated by major accident construction projects as a result of progress in construction work, and to derive the major causes and causes for each safety management activity that affect safety accidents.

This study based on the clinical analysis of 42 cases of bronchiectasis treated by surgical resection at the Department of Thoracic and Cardiovascular Surgery, Chosun University Hospital, during 6 years period from 1986 to 1991. The 42 patients with bronchiectasis were composed of 33 males and 9 females, and the peak incidence of age was in the 3rd decade. The clinical symptoms were cough, purulent sputum, hemoptysis and dyspnea. Based on the morphological classification by bronchograpgy, the common type was present in 19 cases[45%] of cylindrical type. The frequently involved site was left lower lobe, and so left lower lobectomy was the most frequently performed method of surgical resection. Postoperative complications were occurred in 8 cases[18%], such as wound infection, atelectasis, pleural effusion, hemothorax, but there were no fatal cases.

Spontaneous pneumothorax is an accumulation of air in the pleural space with collapse of the lungs in the absence of external chest trauma. In this clinical study were analyzed of 369 cases of spontaneous pneumothorax experienced at the department of Thoracic and Cardiovascular Surgery, College of Medicine, Chosun University during from January, 1986 to December, 1992.The peak incidence of age was in 3rd decade and more predominantly in male than women [5:1]. Pulmonary tuberculosis was most common etiologic condition and frequently symptoms were dyspnea and chest pain. The site of pneumothorax was Rt.in 48%, Lt.in 45% and both in 7%. The common accompanied diseases were hydrothorax, pyothorax and hemothorax. In 166 cases [45%] were treated by closed thoracostomy only, in 43 cases [12%] were treated by closed thoracostomy & chemical pleurodesis with Tetracycline and in 145 cases [39%] were treated by open thoracotomy. The most serious complication, one case of pulmonary edema, was developed after closed thoracostomy and fatal.

Since tuberculosis was a common pulmonary disease in Korea, Aspergillosis was easily misdiagnosed as tuberculosis and an acute form of Aspergillosis was misinterpreted as pneumonia because of their similarities in the X-ray findings. This investigation is designed to illustrate the clinical features and preoperative diagnosis and surgical role in the management of this disease. In a retrospective review of operative cases from Jan. 1963 through Dec. 1983, 36 cases were analyzed. Peak age incidence lies in the 3rd decade [41.7%]. All cases had a history of treatment with antituberculous drugs under diagnosis of pulmonary tuberculosis and the most common chief complaint was hemoptysis [69.5%]. Only nine cases [25%] showed cavitary lesions with mycetoma and preoperative sputum study for fungus showed low positive valve [42.3%]. Anatomical location of lesion was located mainly upper lobe [66.7%] and most of cases were managed by lobectomy. We experienced 7 cases of complication; they were postoperative empyema, hepatic failure, esophageal varix bleeding. Postoperative pathologic findings showed that 29 cases [80.5%] were combined with tuberculosis 3 cases were combined with bronchiectasis and 4 cases were not combined with other disease. In conclusion, when the patient has a longstanding history of pulmonary tuberculosis and has a hemoptysis, he must be suspected fungus super infection. Resectional surgery is the treatment of choice for symptomatic localized disease and needed resection in asymptomatic patient to prevent possible fatal sequelae in the future.

Bromide($Br^-$) was separated and quantified with $2.8mM-NaHCO_3/2.2mM-Na_2CO_3$ by Ion Chromatography. Bromide was eluted at 8.9 min. and the detectetion limit was 2.5 ng. We compared with bromide concentration in normal or methylbromide intoxicated bloods and tissues. Bromide concentrations were 2.0~5.8 ppm in normal bloods and 1.0~5.3 ppm in normal tissues. In fatal cases of methylbromide intoxication, blood bromide concentrations (4 cases) of 74.2~139 ppm and tissue bromide concentration (1 case) of 76 (heart)~201 (lung) ppm were detected. In fatal cases, blood bromide concentrations. were 12~22 times higher than those of normal bloods.

Purpose: In Korea, few studies have examined the acute toxicity of anti-obesity drugs. The purpose of this study is to analyze the general characteristics and clinical aspect of acute anti-obesity drug intoxication. Methods: We retrospectively investigated patients admitted to the emergency department after anti-obesity drug intoxication between March, 2004 and February, 2012. The medical records of these patients were reviewed for demographic data, toxicologic history, time elapsed to presentation, clinical symptoms and signs, treatment, and outcome. Results: There were a total of 18 anti-obesity intoxication cases during the study period; of 16 which were included in our study. The purchasing route of the anti-obesity drug was mainly through a doctor's prescription (68.8%), however, some were obtained through the internet and the pharmacies. The mean time to The most commonly ingested antiobesity drug was sibutramine (31.3%) and many of the cases (62.5%) were multi-drug ingestions. The most common clinical manifestations were gastrointestinal symptoms (94%), but, CNS symptoms (75%) and cardiovascular symptoms (75%) were almost equally present. 13 patients (81%) were discharged after clearance of toxic symptoms and signs with a mean observational period of 7.0 hours. 3 patients were admitted for observation and treatment; of which 1 patient died due to fatal complications. Conclusion: Most anti-obesity intoxications show mild toxicity and a nonfatal clinical course. However, the recent trend toward prescribing psychostimulant anti-obesity medication, which can be fatal after an acute overdose, calls physicians' attention to treating of anti-obesity intoxications.

Purpose: The aim of this study was to investigate toxic exposures in emergency centers with using a toxic exposure surveillance system-based report form as a preliminary study. Methods: We retrospectively reviewed the medical records of toxic exposure patients who visited emergency centers from January to December 2008. Results: 3,157 patients from 11 emergency centers were enrolled. Males were involved in 47.9% of the total cases of exposure and in 60.1% of the cases of fatal exposure. Suicidal intent was the most common (61.0%) reason and most (87.4%) fatal exposures were suicidal. Pesticides were involved in 30.7% of the cases and sedative/hypnotics/antipsychotics were involved in 20.5%. The substances most frequently involved in fatalities were pesticides, and a 48.4% fatality rate was recorded for paraquat exposure. Conclusion: The toxic exposure data showed the preliminary poisoning events in emergency centers. It is recommended that toxicology professionals should develop a toxic surveillance system and serial reporting should be performed.

Purpose : Adenoviruses(Ad) have been shown to play an important role in the etiology of severely acute respiratory diseases, particulary in infants and young children, and the occurrence of fatal outcome and chronic pulmonary sequelae in association with adenoviral infection has been a cause of great interest and concern. This report presents the resul of a retrospective analysis on 30 cases of lower respiratory infection from which adenovirus was isolated. Patients & Methods : The 30 patients in this study represent all detected cases of adenovial infection out of 240 children who were admitted to Sang Sung Medical Center between February to June 1996 showing signs and symptoms of lower respiratory tract infection. The diagnosis of adenovirus infection was based on microscopic visualization of typical cytopathic effect in HEp-2 tissue culture and used monoclonal Ab with nasopharyngeal aspiration. Results : The male/female ratio was 2:1 and the majority of age range was below 36months. Clinical diagnoses in all 30 patients were pneumonia(n=21), bronchitis and Bronchiolitis(n=5) and ARDS(n=4). We recieved the most of patients in the month of May. The chief complaints were fever(93.3%) and cough(80%) and extrapulmonary symptoms were diarrhea(n=5), seizure(n=4), abdominal pain(n=1). The mean duration of fever was $11.95{\pm}6.54$days. Physical examination on admission were crackles(73.3%), coarse breathing sounds(60%), hepatosplenomegaly(33.3%), decreased brething sounds(30%). In WBC counts, 8cases were below $4000/mm^3$ and 14 cases were above $10,000/mm^3$. In platelets counts, 4cases were below $150,000/mm^3$ and 10 cases were above $450,000/mm^3$. 21 cases were above 1 in CRP. GOT and GPT were abnormal in some cases. Chest X-ray revealed diffuse pulmonary infiltration(n=15), pleural effusion(n=6), consolidation(n=4) and hyperaeration(n=3). Seven patients were treated at the peditric intensive care unit with respiratory support and high dose of gammaglobulin. However, one patients died even through he was treated with NO ventilation and high frequency ventilation. Conclusion : Those with adenoviral pneumonia and respiratory infection having long fever duration and symptoms like bacterial pneumonia must be carefully differentiated in order to provide proper treatement and preventive measures due to possible fatal outcome.

True extracranial carotid artery aneurysms (ECCAs) are uncommon. Atherosclerosis is the most common etiological factor. Neck pain, a pulsatile mass and murmur at auscultation are the most common symptoms. ECCAs may exhibit severe clinical manifestations due to complications. Cases of rupture can be fatal. There is a risk of distal embolization and stroke in thrombosed cases. We discuss two cases of enlarged ECCA treated surgically in the light of the most recent literature.
