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.

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.

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.

PURPOSE: An overactive bladder (OAB) may be defined as urgency that is a sudden, compelling, difficult to defer desire to pass urine that is usually accompanied by frequency and nocturia and possibly by incontinence. Obesity and old age are two factors in various causes of OAB. Several epidemiologic studies have identified positive associations among obesity, old age, urinary incontinence, and OAB. However, although exercise has been known to improve obesity and reduce incontinent urine loss, little research has been done in elderly women. Therefore, we investigated the effects of exercise on obesity-related metabolic factors, blood lipid factors, and OAB symptoms in elderly Korean women. METHODS: Twenty-one women aged between 69 and 72 years were recruited from the Seoul senior towers in Korea. All subjects worked out on a motorized treadmill and stationary cycle for 40 minutes, respectively, and performed resistance exercise for 30 minutes once a day for 52 weeks. Body composition, blood pressure, blood lipids, OAB symptom score, and King's health questionnaire were investigated and analyzed. RESULTS: Before performing physical exercise, all subjects showed increased OAB symptoms in association with enhanced body mass index (BMI), percentage fat, and blood lipid profiles. However, physical exercise for 52 weeks suppressed BMI, percentage fat, and blood lipid profiles and thus improved OAB symptoms. CONCLUSIONS: We suggest that long-term physical exercise can be a valuable tool for remarkable improvement of OAB.

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.

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.
