This study provides a statistical analysis of 1,226 cases of death occurring in Area 8, Seoul Metropolitan Police Agency (Gangseo, Yangcheon, and Guro Police Stations) from January 1 to December 31, 2017. There were 427 postmortem inspection cases in Gangseo, 393 in Yangcheon, 377 in Guro, and 29 in other areas. The number of autopsy cases was 69 in Gangseo, 70 in Yangcheon, 86 in Guro, and seven in other areas. According to the postmortem inspection reports, there were 593 cases of natural death and 336 cases of unnatural death, while in 297 cases the cause of death was unknown. Of the 297 unknown cases, autopsy rates from each police station were as follows: 54 of 99 cases (54.5%) in Gangseo, 60 of 101 cases (59.4%) in Yangcheon, 67 of 93 cases (72.0%) in Guro, and in all four cases (100%) from other areas. Unnatural deaths included 215 cases of suicide, nine cases of homicide, and 64 accidental death, while 48 cases were undetermined. Among the unnatural deaths, the cause of death included 138 cases of hanging, 72 cases of falls from a height, and 32 cases of poisoning. Since this statistical study is based on actual postmortem inspection data for 1,226 cases of death in the eight areas of Seoul (excluding deaths from traffic accidents), it raises issues relating to the current postmortem inspection system, and can be used as reference material for a comprehensive overview of causes of death.

Since March 1, 2015, the National Forensic Service Seoul Institute has commenced postmortem inspections at the death scene in agreement with the Korean National Police Agency. Included regions were mainly Seoul Metropolitan Police Agency Wide Area 8 (Gangseo, Yangcheon, Guro police stations), and several other areas. In total, 837 postmortem inspection cases from March 1 to December 31, 2015, were analyzed statistically. Of these, 168 were autopsy cases, and the rates were 20% (67 cases) in Gangseo Police, 14.5% (30 cases) in Yangcheon Police, and 22% (57 cases) in Guro Police stations. For 269 cases of “unknown cause of death”, the autopsy rates were 44% in Gangseo Police, 36% in Yangcheon Police, and 47% in Guro Police stations. For 82 cases of fall from height, autopsy rates were 17% (n=14). Of the 133 cases of hanging, 121 cases were classified as suicide at the scene with a 2.5% (n=3) autopsy rate. Twelve cases were classified as an undetermined manner of death at the scene with a 33% (n=4) autopsy rate. The distribution of the “manner of death” was natural death for 29% (n=250), unnatural death for 38% (n=318), and other and undetermined manner of death for 32% (n=269) of cases. Proportions of dispatch times were 49.2% (412 cases) during work hours (09:00-18:00), 15.7% (n=131) during evening hours (18:00-21:00), 13% (n=110) at night (21:00-24:00), 10% (n=88) at dawn (24:00-06:00), and 11% (n=96) during morning hours (06:00-09:00). The male to female sex ratio was 1.96:1 (556:281). These statistics are valuable for evaluation of postmortem inspections by experts.

From January 1, 2016 to December 31, 2016, a total of 1147 postmortem inspection cases in Area 8, Seoul Metropolitan Police Agency (Gangseo, Yangcheon, and Guro police stations) were statistically analyzed. Autopsies were performed in 205 cases (17.9%), and the autopsy rates were 17.6% (75/426 cases) in the Gangseo police station, 9.5% (34/357 cases) in the Yangcheon police station, and 24.3% (82/337 cases) in the Guro police station. For 288 cases with an unknown cause of death, the autopsy rates were 70.0% (60/87 cases) in the Gangseo police station, 28.6% (26/91 cases) in the Yangcheon police station, and 63.1% (65/103 cases) in the Guro police station. For 65 cases due to fall from height, the autopsy rate was 7.7% (n=5). Of the 187 cases due to hanging, 155 cases were classified as suicide at the scene with a 4.5% (n=7) autopsy rate and 32 cases were classified as an undetermined manner of death at the scene with a 15.6% (n=5) autopsy rate. The distribution of the “manner of death” was natural death, 45% (n=516); unnatural death, 29.9% (n=343); and other and undetermined, 25.1% (n=288). Proportions of dispatch times were 50.9% (584 cases) during work hours (09:00–18:00), 13.8% (n=158) during evening hours (18:00–21:00), 13.4% (n=154) at night (21:00–00:00), 11% (n=126) at dawn (00:00–06:00), and 10.9% (n=125) during morning hours (06:00–09:00). The male-to-female ratio was 1.86:1 (746:401). These statistics are valuable for the evaluation of postmortem inspections by experts.

PURPOSE: We tried to evaluate the difference in the expression of carbonic anhydrase (CA) III and heat shock protein (Hsp) 70 between laryngopharyngeal reflux disease (LPRD) and non-LPRD patients. MATERIALS AND METHODS: The study involved 28 patients who underwent laryngeal microsurgery due to benign laryngeal disease from March to August 2008. Reflux symptom index (RSI) and reflux finding score (RFS) were measured for each person, and they were assigned either to the LPRD group (n=10) or non-LPRD group (n=18). Tissue samples were obtained from the mucosa of posterior commissure, and immunohistochemistry (IHC) staining of CAIII and Hsp70 was performed. The IHC scores were measured and compared with clinical features including RSI and RFS. RESULTS: Total 10 patients were assigned as LPRD group, and 18 patients were as control group. The mean IHC score of CAIII and Hsp70 was 1.70+/-1.06 and 1.90+/-0.88, respectively, in LPRD patients, whereas the mean IHC score of CAIII and Hsp70 was 0.78+/-0.73 and 0.94+/-0.87, respectively, in non-LPRD patients. The difference between two groups was statistically significant (p<0.05). CONCLUSION: CAIII and Hsp70 expressions were higher in LPRD patients that in non-LPRD patients, suggesting the possibility as one of biomomarker in LPRD diagnosis.

Forensic autopsies were performed on 1,821 cases in 2014 and 2,024 cases in 2015 at the National Forensic Service Seoul Institute. Based on the autopsy reports, 103 cases (5.7%) in 2014 and 130 cases (6.4%) in 2015 were selected as unnatural deaths caused by fatal intoxication. The cases were divided into five groups. The first group had ethanol intoxication, the second had drug intoxication, the third had agrochemical intoxication, the fourth had cyanide intoxication, and the fifth had miscellaneous intoxications. Of the 233 cases, 202 had death certificates. Of these 202 cases, 169 (83.7%) had an undetermined manner of death (MOD); 17 (8.4%) had an unnatrual MOD and intoxication was the cause of death (COD); nine (4.5%) had an unnatural MOD, but the COD was not intoxication; seven (3.5%) had a natural MOD and disease as a COD. The predictive ratios of intoxication as a COD were compared with the death certificates and the police death scene investigation results. The death certificates and the police investigation results showed predictive ratios of 8.4% and 55.2%, respectively, for intoxication as a COD. The discrepance in these predictive ratios and relatively low predictive ratio of police investigation results mean that intoxicated deaths have been underevaluated; thus, some homicides or intentional deaths were probably missed under South Korea's death investigation system. Doctors who specialize in forensic medicine need to supervise the entire postmortem examination process and emergency blood toxicological analysis should be performed in South Korea.

BACKGROUND: From May to July 2015, the Republic of Korea experienced the largest outbreak of Middle East respiratory syndrome (MERS) outside the Arabian Peninsula. A total of 186 patients, including 36 deaths, had been diagnosed with MERS-coronavirus (MERS-CoV) infection as of September 30th, 2015. MATERIALS AND METHODS: We obtained information of patients who were confirmed to have MERS-CoV infection. MERS-CoV infection was diagnosed using real-time reverse-transcriptase polymerase chain reaction assay. RESULTS: The median age of the patients was 55 years (range, 16 to 86). A total of 55.4% of the patients had one or more coexisting medical conditions. The most common symptom was fever (95.2%). At admission, leukopenia (42.6%), thrombocytopenia (46.6%), and elevation of aspartate aminotransferase (42.7%) were observed. Pneumonia was detected in 68.3% of patients at admission and developed in 80.8% during the disease course. Antiviral agents were used for 74.7% of patients. Mechanical ventilation, extracorporeal membrane oxygenation, and convalescent serum were employed for 24.5%, 7.1%, and 3.8% of patients, respectively. Older age, presence of coexisting medical conditions including diabetes or chronic lung disease, presence of dyspnea, hypotension, and leukocytosis at admission, and the use of mechanical ventilation were revealed to be independent predictors of death. CONCLUSION: The clinical features of MERS-CoV infection in the Republic of Korea were similar to those of previous outbreaks in the Middle East. However, the overall mortality rate (20.4%) was lower than that in previous reports. Enhanced surveillance and active management of patients during the outbreak may have resulted in improved outcomes.

Cholangitis and cholecystitis are intra-abdominal infections that show poor prognosis upon progression to sepsis and multiorgan failure. Administration of antibiotics with high antimicrobial susceptibility and removal of infected bile at the initial treatment are important. After undergoing ERCP for diagnostic purposes, a 58-year-old man developed acute cholangitis and cholecystitis accompanied by rhabdomyolysis, multi-organ failure, and severe sepsis. Broad-spectrum antibiotics with bedside endoscopic nasobiliary drainage were administered, but clinical symptoms did not improve. Therefore, bedside EUS-guided transgastric gallbladder aspiration and lavage was performed, resulting in successful treatment of the patient. We report the above described case along with a discussion of relevant literature.

Thermal burns of the larynx after swallowing hot foods or drinks are frequently common in children, but are known to be extremely rare in adults. We report the case of a male adult who, upon swallowing hot food, experienced a burn of the larynx with airway obstruction. Since airway obstruction usually occurs within hours of burn of the larynx, the importance of persistent airway management is emphasized in this case.

Since laparoscopic liver resection was first introduced in 2001, Korean surgeons have chosen a laparoscopic procedure as one of the treatment options for benign or malignant liver disease. We distributed and analyzed a nationwide questionnaire to members of the Korean Laparoscopic Liver Surgery Study Group (KLLSG) in order to evaluate the current status of laparoscopic liver resection in Korea. Questionnaires were sent to 24 centers of KLLSG. The questionnaire consisted of operative procedure, histological diagnosis of liver lesions, indications for resection, causes of conversion to open surgery, and postoperative outcomes. A laparoscopic liver resection was performed in 416 patients from 2001 to 2008. Of 416 patients, 59.6% had malignant tumors, and 40.4% had benign diseases. A total laparoscopic approach was performed in 88.7%. Anatomical laparoscopic liver resection was more commonly performed than non-anatomical resection (59.9% vs 40.1%). The anatomical laparoscopic liver resection procedures consisted of a left lateral sectionectomy (29.3%), left hemihepatectomy (19.2%), right hemihepatectomy (6%), right posterior sectionectomy (4.3%), central bisectionectomy (0.5%), and caudate lobectomy (0.5%). Laparoscopy-related serious complications occurred in 12 (2.8%) patients. The present study findings provide data in terms of indication, type and method of liver resection, and current status of laparoscopic liver resection in Korea.
