OBJECTIVES: There was an outbreak of foodborne and waterborne disease among high school students at Okcheon in June, 2018. First attack occurred June 5(th) but seven days later it was notified. The purpose of this investigation was to evaluate the pathogen of outbreak and cause of delayed notification. METHODS: First, we did a questionnaire survey for 61 cases and 122 controls to find what symptoms they had and whether they ate foods or drank water from June 2(nd) to June 12(th). Second, we investigated the environment of cafeteria and drinking water. Third, we examined specimen of cases and environment to identify bacteria or virus. RESULTS: Attack rate of this outbreak was 7.8%. Drinking water was strongly suspected as a source of infection in questionnaire survey but we could not find the exact time of exposure. Norovirus was identified in specimen of cases (2 students), drinking water (at main building and dormitory) and cafeteria (knife, dishtowel, hand of chef) CONCLUSIONS: We decided norovirus as the pathogen of this outbreak based on the clinical features of cases with diarrhea vomiting, abdominal pain and recovery within 2 or 3 days after onset, outbreak due to drinking water and microbiologic examination, And the cause of delayed notification might be the non-existence of the nurse teacher at that time and the lack of understanding of teachers on immediate notification under the outbreak. To prevent the delayed notification, notification system about outbreak of foodborne and waterborne disease in school is needed to be improved.

On July 6, 2009, an outbreak of gastroenteritis occurred among middle school students in Incheon. An investigation to identify the source and describe the extent of the outbreak was conducted. A retrospective cohort study among students, teachers, and food handlers exposed to canteen food in the middle school was performed. Using self-administered questionnaires, information was collected concerning on symptoms, days that canteen food was consumed, and food items consumed. Stool samples were collected from 66 patients and 11 food handlers. The catering kitchen was inspected and food samples were taken. Of the 791 people who ate canteen food, 92 cases became ill, representing an attack rate of 11.6%. Thirty-one (40.3%) of the 77 stool specimens were positive for Campylobacter jejuni. Interviews with kitchen staff indicated the likelihood that undercooked chicken was provided. This is the first recognized major C. jejuni outbreak associated with contaminated chicken documented in Korea.

We report a case of pityriasis versicolor atrophicans in a 20-year-old woman who presented with chronic multiple brownish atrophic macules and patches on chest and back. The lesions had developed six years ago and the patient had used topical medication including steroid ointments for the last two years prior to visiting our clinic. KOH examination was positive, so skin biopsy was performed and the diagnosis of pityriasis versicolor atrophicans was made. Since our patient had applied topical steroids for some time, it was difficult to rule out steroid-induced atrophy in a common tinea versicolor. Also, differential diagnosis was performed with respect to other skin diseases manifesting with cutaneous atrophy including anetoderma.

PURPOSE: Effectiveness of the performance of bystander cardiopulmonary resuscitation (CPR) has a decisive impact on the outcomes for out-of-hospital cardiac arrest patients who receive it. After initial CPR education, CPR performance for those trained declines over time. Public education in CPR is commonly recommended to be repeated every 2 years. In this study, we evaluated the willingness of those who have been CPR trained to perform CPR as impacted by their training experience. METHODS: The staff of a small firm received 2 hours of primary CPR education. Two years later, their CPR training was repeated in an identical manner. Participants answered a questionnaire regarding their willingness to perform bystander CPR. Those who answered that they wouldn't perform bystander CPR were asked to select their reason. We also inquired about what they viewed as the most difficult phase of CPR performance, and collected their opinions about the overall necessity and appropriate time period for re-education. RESULTS: Those who answered 'definitely yes' to 'willingness to perform to CPR' increased from 36.6% before primary CPR education to 74.2% afterward. But 2 years later and before re-education, only 30.1% answered 'definitely yes' to 'willingness to perform CPR'. Meanwhile, 41.2% and 29.4% answered that 'fear of legal liability' and 'fear of poor knowledge/performance' were the reasons why they would not perform bystander CPR. Ventilation was the most difficult stage in CPR identified by 34% of the participants, and 18.4% answered that chest compression was the most difficult stage in CPR. 93.6% answered that they should receive CPR re-education. CONCLUSION: The willingness to perform bystander CPR declined significantly after 2 years. Therefore routine public re-education for bystander CPR is necessary.
