Since the book "Final Exit: The Practicalities of Self-Deliverance and Assisted Suicide for the Dying" was published in 1991, there has been a worldwide increase in the number of cases of suicidal asphyxiation using helium gas. However, no domestic reports have been published thus far. Recently, we encountered a case of asphyxial suicide by inhalation of helium from inside a plastic bag. Subsequently, we reviewed the records of the Scientific Crime Analysis System of National Police Agency of Korea. There were 17 cases of helium-associated asphyxial suicides between January 1, 2000 and June 30, 2012. The average age of the deceased was 30.6 years with a male to female ratio of approximately 5:1. Thirteen of 17 such deaths occurred in the victims'houses. In all cases, the method of death involved placing a plastic bag over the head with a hose attached to helium tanks. In 6 of 17 cases, the decedents had psychiatric disorders such as depression. As neither characteristic signs of death nor conventional methods for detecting helium gas exist, a thorough investigation of the death scene and the decedents'environment is extremely vital for confirming death due to helium asphyxiation.

In March 2014, a 39-year-old Korean male presented with a 6-month history of various nonspecific symptoms including dizziness, fatigue, asthenia, irritability, elevated blood pressure, palpitation, eyestrain, and tinnitus. His occupational history revealed that he had been working as an indoor firing range manager for 13 months; therefore, he was subjected to a blood lead level (BLL) test. The test results showed a BLL of 64 µg/dL; hence, he was diagnosed with lead poisoning and immediately withdrawn from work. As evident from the workplace environmental monitoring, the level of lead exposure in the air exceeded its limit (0.015–0.387 mg/m³). He received chelation treatment with calcium-disodium ethylenediaminetetraacetic acid (1 g/day) for 5 days without any adverse effects. In the follow-up results after 2 months, the BLL had decreased to 9.7 µg/dL and the symptoms resolved. This report represents the first occupational case of lead poisoning in firing ranges in Korea, and this necessitates institutional management to prevent the recurrence of poisoning through this route. Workplace environmental monitoring should be implemented for indoor firing ranges, and the workers should undergo regularly scheduled special health examinations. In clinical practice, it is essential to question the patient about his occupational history.

OBJECTIVE: We analyzed the clinical features of amniotic fluid embolism confirmed by autopsy or clinical dicision for making a plan of rapid diagnosis and intensive emergency care. STUDY DESIGN: We experienced 2 clincal cases in Ewha Mokdong Hospital and Severance Hospital at 1995, and reviewed the medical record & autopsy report of 15 cases in National Institute of Scientific Investigation from Jan, 1991 to Dec, 1995. RESULTS: The mean maternal age was 31+/-3 years. The mean gestational age was 40+/-1 weeks. The number of delivery were 1.4+/-0.8. The number of abortion history. were 2.6+/-2. The sexuality of fetus were six males (35 %), five females (29%), and unknown six cases (35 %) and the fetal mortality rate was 29 % (5 cases). The initial clinical symptoms and signs were hypotension (12 patients, 71%), vaginal bleeding(ll patients, 65%), cardiac arrest (6 patients, 35 %), dyspnea (5 patients, 29 %), and seizure (2 patients, 12%). In the case of normal spontaneous vaginal delivary (NSVD), the symptoms occurred during induction in 3 (18%), during delivery in 1 (6%), and after delivery in 9 (53%). In the case of Cesarean section, the symptoms occurred during section in 2 (12%), and after section in 1 (6%). There are one case whose symptoms occurred during 3rd gestational period. CONCLUSIONS: We should alert for the amniotic fluid embolism in the clinical findings of acute collapse and vaginal bleeding, respiratory symptoms, and seizure at any peripartum. With eary suspicion of this disease and aggressive intensive care we can reduce amniotic fluid embolism mortality rate and it's legal problem.

BACKGROUND: Atopic dermatitis (AD) is primarily influenced by environmental factors including exposure to pollutants and indoor allergens (particularly, house dust mites). Al-though house dust mite antigens are the most prevalent components of indoor allergens in Korea, cockroaches also can be considered to act as an important allergen. OBJECT: This study was done to evaluate the differences in three different atopic patch test (APT) techniques, and the relationship between APT and skin prick test, total IgE, and specific serum IgE level using cockroach allergen. Methods: We performed patch test in 57 patients with AD and 30 normal controls on clinically lesional and normal appearing skin with German cockroach (GC) allergens (extract, as is) in three different techniques (standard, scratch, DMSO). Reactions were evaluated after 48hours, and compared with the results of skin prick test, total and specific IgE levels. Detailed atopy history and severity scoring were taken. RESULTS: In the GC (whole body) prick test positive group, there was 1263.02 IU/ml of total IgE, and this amount was significantly higher than GC (whole body) prick test negative group who had 549.46 IU/ml (P<0.05). The positive reaction rate to whole body of American cock-roach (AC) was significantly higher in the patient group than control group (p<0.05), but the positive rate to whole body of GC was high, but not significantly high in the patient group (p=0.053). There were significant differences in positive patch test reactions to either Ext or As is between patient group and control group (p<0.05). The positive rate to As is was significantly higher than to Ext in either lesional skin or non-lesional skin in patient group (p<0.05). But there were no considerable differences in positive reactions to either Ext or As is between 3 different methods (standard, scratch, DMSO mix) in both lesional and non-lesional areas (p>0.05). There was no significant relationship between the positive reactions to patch test and prick test to Ext and As is antigen. The APT results showed no significant concordances with skin prick test and RAST for cockroach antigens. CONCLUSIONS: APT seems to be a different dimension of atopic skin inflammation and may pro-vide further diagnostic information in addition to a patient's history, skin prick test, and RAST results.

A 46-year-old woman presented with multiple purpuric skin rashes together with splenomegaly and thrombocytopenia. The resected spleen weighed 720 gm, and contained multiple, discrete, dark red, bulging nodules throughout the entire splenic parenchyma. Microscopically, the nodules revealed various range of endothelial cell proliferation which included cavernous vasculature, anastomosing vascular channels, papillary intravascular growth and solid pattern. Intrasinusoidal sequestration of platelets along with extramedullary hematopoiesis was present in the neoplastic vascular spacws. Neither exposure to thorotrast nor vinyl chloride was nonfirmed. Ultrastructurally, the tumor cells demonstrated a row of pinocytotic vesicles, occasional intercellular junctional structures, and the paucity/absence of filamentous structures or Weibel-Palade bodies supports origin of sinus lining type cells. After splenectomy, the thrombocyte count returned to normal. We conclude this is the first case of primary splenic angiosarcoma with Kasabach-Merritt syndrome in Korean literature.
