Congenital lobar emphysema has the clinical features of an air block' syndrome with- out the evidence of pulmonary infection or intrabronchial foreign body. The hyperinflated lung causes a compression of uninvolved lobes creating respiratory distress, cyanosis within the first weeks of life. We experienced a case of congenital lobar emphysema diagnosed incidentally by chest reontgenogram in an infant with frequent upper respiratory infection within a few weeks of life. Chest X-ray revealed extensive emphysematous changes in the left upper lobe, shifting of heart and medistinum to the right and compression of the right lung. Respiratory distress, cyanosis and chest wall retraction ensued and left upper lobe Lobectomy was performed successfully.

Medicolegal autopsy is a vital tool for obtaining reliable injury mortality data. This study statistically analyzed data obtained from medicolegal autopsies performed in Korea in 2013. The aim of this study was to analyze various aspects of the 4,861 deaths that were categorized as unusual in Korea in 2013. A total of 4,861 deaths were analyzed by gender, age, manner of death, and cause of death. Of the 4,861 deaths, 3,542 (73.3%) were of men and 1,302 (26.7%) were of women. With respect to the manner of death, 54.4% were recorded as unnatural deaths, 38.8% were natural deaths, and 6.9% had unknown causes. Of the 2,642 unnatural deaths, 45.0% were determined to be accidental deaths, 26.3% suicidal, 16.9% homicidal, and 11.8% undetermined. Of the total number of unnatural deaths, 42.1% were trauma-related deaths, for which falling down accounted for 33.8%. Asphyxiation accounted for 16.0% of unnatural deaths, and of these, the predominant cause was hanging (58.8%). In addition, 14.4% of deaths were due to drowning, 12.9% poisoning, 11.0% thermal injuries, 1.8% complications arising from medical procedures, and 0.8% electrocution, starvation, or neglect. Among the 1,886 natural deaths, heart diseases accounted for 52.0% and vascular diseases accounted for 16.9%. Of the 196 deaths among children under the age of 10 years, 41.8% were recorded as unnatural deaths, 45.1% were natural deaths, and 1.5% had unknown causes.

Background: The purpose of this study was to assess the reliability and validity of the 3-item version of the Work Engagement Scale (WES-3), which is based on the Job DemandsResources (JD-R) model and was used in the 5 th Korean Working Conditions Survey (KWCS). Methods: This study used data from the 5th KWCS (n = 50,205), which was conducted in 2017 with a sample of the Korean working population. The survey gathered comprehensive information on working conditions to define workforce changes and the quality of work and life. The reliability and internal consistency of the WES-3 were assessed using the corrected item-total correlation and Cronbach's alpha coefficient. Confirmatory factor analysis (CFA) was used to test the construct validity of work engagement. The convergent validity was assessed using the correlation with the WHO-5 well-being index. Correlations between work engagement and JD-R factors were also calculated. Results: The Cronbach's alpha for work engagement was 0.776, indicating acceptable internal consistency. The model comprising 3 work engagement and 2 burnout items showed an excellent fit (χ2 : 382.05, Tucker-Lewis index: 0.984, comparative fit index: 0.994, root mean square error of approximation: 0.043). The convergent validity was significant (correlation coefficient: 0.42). Correlations with burnout and job demands were negligible, whereas correlations with job resources and job satisfaction were weakly positive. Conclusions The results of our study confirm that the WES-3 has acceptable reliability and validity.

A 39-year-old hairdresser developed sodium bromate poisoning after drinking a cup of hair neutralizer in a suicide attempt. This is the first case of visual loss afteringestion of sodium bromate. Only few cases are as a cause of acute renal failure reported in medical literature. She presented 1 day later with anuria, required hemodialysis. Sensorineural hearing loss, often a characteristic finding, was developed.

We experienced two cases of Boerhaave syndrome (spontaneous esophageal rupture). The first patient was a 62-year-old male who presented epigastric pain after several violent vomitings associated with alcohol ingestion. Diagnosis was done early and promptly in our emergency center and then definitive treatment was done only after 12hrs from onset of his symptom and he was discharged in relatively good condition 256ays after his admission. The second patient was a 44-year-old male who was transfered to our emergency center with chest pain, dyspnea and fever after vomitings associated with autobicycle accident. Diagnosis was delayed due to initial trauma oriented evaluation and incidious develpement of typical clinical findings and then he was managed conservatively but he died of multiple organ failure due to sepsis. We report these cases with literature review.

The authors report a case of angiographycally occult intracranial vascular malformation. The patient had huge calcified mass at left frontoparietal area. The preoperative diagnosis was a slowly growing benign tumor. The mass was very hard and so vascular malformation was not suspected even during the operation. Pathologic report revealed arteriovenous malformation.

Tali are one of the essential components for weight bearing and play an important role in the foot action. The three calcaneal articular facets of the talus are believed to have diverse morphological variations. However, so far, analysis of the articular facets has not been performed in Korean. In the present study, we classified calcaneal articular facets of the talus and measured several parameters of this bone in Korean adults. Seventy six dry tali (male, 47; female, 29; right, 38; left 38) obtained from forty six (male, 28; female, 18) Korean adult cadavers were used for the investigation. The average age of the cadavers was 64-year-old. Types of calcaneal articular facets of the talus were classified as follows: Type A, a type with three separated facets; Type B, types in which anterior and middle facets are connected, but distinguished by a ridge. Type B was subdivided into B1 (having a notch that separates the two facets partially) and B2 (without a definite notch, thus the two facets appear to be continuous smoothly); Type C, a type with combined anterior and middle facets. Type B was found to be the most common type (60.5%), and the incidence of its subtype B1 (28.9%) and B2 (31.6%) was similar to each other. Type C was noted in 30.3% of the cases, and type A was ranked the lowest (9.3%). Compared to the opposite gender, type C occurred more frequently in males, while type B1 was more prevalent in females. The length of the talus was somewhat longer in males (55.9 mm) than in females (52.8 mm). However, there was no difference between the two sexes in the width of the talus. We could confirm that morphology of calcaneal articular facets of the talus is different between males and females. Also, our results indicate that characteristics of the facets of Korean differ from those of other races. The characteristics of calcaneal articular facets of the talus disclosed by the present study may provide valuable information for the understanding of motor mechanics of the foot in Korean.

OBJECTIVE: It has been suggested that elevated cardiac troponin T (cTnT) level is a marker of increased risk of mortality in acute ischemic stroke and subarachnoid hemorrhage (SAH). However, the association of serum cTnT level and prognosis of intracerebral hemorrhage (ICH) has been sparsely investigated. The aim of this study was to identify the relationship between cTnT level and the outcome in patients with spontaneous ICH. METHODS: We retrospectively investigated 253 patients identified by a database search from records of patients admitted in our department for ICH between January 1, 2003 and December 31, 2007. The patients were divided into 2 groups; the patients in group 1 (n=225) with serum cTnT values of 0.01 ng/mL or less, and those in group 2 (n=28) with serum cTnT values greater than 0.01 ng/mL. RESULTS: The serum cTnT level was elevated in 28 patients. There were significant differences in sex, hypertension, creatine kinase-myocardial band, midline shift, side of hematoma, and presence of intraventricular hemorrhage between the 2 groups. Logistic regression analysis identified the level of consciousness on admission, cTnT and midline shift as independent predictors of hospital mortality. CONCLUSION: Theses results suggest that increased serum cTnT level at admission is associated with in-hospital mortality and the addition of a serum cTnT assay to routine admission testing should be considered in patients with ICH.
