Analysis of Death due to Poisoning in Gwangju and Jeollanam-do Areas / 대한법의학회지

This study examined 190 cases of confirmed poisoning, as determined by autopsy findings, as well as alcohol and toxicant concentrations in post-mortem specimens. Judicial autopsies were performed from January 2007 to December 2014 at Department of Legal Medicine, Chonnam National University Medical School, the National Forensic Service Gwangju Institute, and St. Carollo Hospital. We analyzed the incidence of poisoning according to region and season in terms of year, sex, age, and classification of toxicants. In the regional classification, the number of deaths due to poisoning in Jeollanam-do and Gwangju areas was similar when considering autopsy numbers. The incidence was higher in autumn and spring than in summer and winter, and a large number of deaths occurred in 2008 and 2014. Additionally, the number of male deaths was approximately twice the number of female deaths, with the age of 50-59 being the most common age group. Pesticides comprised the largest number of deaths due to poison, followed by alcoholism, carbon monoxide, treatment drugs, and cyanic acid, in that order.

Incidence rate of Aneurysmal SAH in Gwangju City and Jeollanamdo Province in 2007

OBJECTIVE: The incidence of subarachnoid hemorrhage (SAH) worldwide varies considerably. In spite of many reports about the incidence of SAH, there has been no report about the incidence of SAH on the basis of the Korean population. The purpose of this hospital-based study was to assess the actual incidence rates of aneurysmal SAH in Gwangju city and Jeollanamdo province. METHODS: All cases of SAH confirmed by computerized tomography (CT) between January 2007 and December 2007 were selected for analysis. For the data collection, three major training hospital and ten general hospitals working the CT in Gwangju city and four major general hospitals in Jeollanamdo province participate in this study. RESULTS: According to the official census of Korea, the population was 1,413,444 in Gwangju city and 1,929,836 in Jeollanamdo province in 2007. There were 163 patients in Gwangju city and 266 patients in Jeollanamdo province confirmed SAH by CT in 2007. The crude and the age- and sex-adjusted annual incidence rates per 100,000 population for all ages in Gwangju city were 11.5 and 12.4 for aneurysmal SAH and in Jeollanamdo province were 13.8 and 10.8. The incidence was higher in women and increased with age. The gender distribution varied with age. At young ages, the incidence was higher in men while after the age of 40 years, the incidence was higher in women. CONCLUSION: In the present study, the age- and sex-adjusted annual incidence rates is 11.8 in Gwangju city and Jeollanamdo province. The incidence was higher in women and increased with age.

A new endemic focus of Gymnophalloides seoi infection on Aphae Island, Shinan-gun, Jeollanam-do

A new endemic focus of Gymnophalloides seoi infection has been discovered on Aphae Island (Shinangun, Jeollanam-do), Republic of Korea. This area, which is referred to as Bokyong-ri, is a small seashore village located in the northern portion of the island. Fecal samples were collected from a total of 57 residents and examined by the Kato-Katz and formalin-ether sedimentation techniques. Helminth eggs were detected in 37 samples (64.9%); 33 samples were positive for G. seoi eggs (57.9%), 4 for Pygidiopsis summa (7.0%), 13 for other heterophyids (22.8%), 1 for Clonorchis sinensis (1.7%), and 1 for Trichuris trichiura (1.7%). Women (70.4%) revealed higher rates of G. seoi infection than did men (46.7%), and individuals older than 50 years of age also evidenced higher rates of G. seoi infection than in other age groups (P<0.05). In worm collection from 13 G. seoi egg positive cases, G. seoi (total 86,558 specimens), Heterophyes nocens (278), Stictodora sp. (10), Heterophyopsis continua (3), P. summa (3), and unidentified flukes (42) were collected. Oysters, the source of G. seoi infection, were collected from an area proximal to the village and 50 were examined for metacercariae; 47 (94%) were found infected and the observed metacercarial density was 9.5+/-8.9 per oyster. The results of this study indicate that Bokyong-ri is a new endemic area of G. seoi infection, with high rates of infection in humans and oysters.
