This study was performed using mealtime atmosphere to characterize the food ecology of Korean children residing in different regions of Korea. A total of 705 elementary school students, 347 girls and 358 boys, were divided into three groups according to the areas where they lived, which included Seoul (n = 230), provincial cities (n = 273) and rural areas (n = 202). The subjects were asked to fill out questionnaires which were categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The results showed that the average height (p < 0.01), weight (p < 0.01) and body mass index (BMIs)(p < 0.01) of the rural group were significantly lower than those of the Seoul and provincial city groups. A significantly higher proportion (10.4%) of the rural group was from disfunctional families, including single parent families, than those of the Seoul (1.7%) or provincial city (4.4%) groups. However, a larger number of children from Seoul ate alone, did not enjoy their meals, and hardly talked to each other during breakfast time, compared to those from the provincial city or rural areas. Also, the proportion (33.0%) of 'good' in balance of meal was the lowest (33.0%) in Seoul of the three areas (p < 0.01). Most of the children answered that they liked having breakfast and dinner with the whole family. In conclusion, the food ecology of elementary children differed according to the regions in which they resided. Although children from Seoul had higher BMIs, their nutritional intake was not satisfactory, and their undesirable food ecology could be a contributing factor.

The current socioeconomic climate has meant more children spend more time alone at home even for dining. This study was performed to characterize modem Korean childrens' food ecology based on mealtime atmosphere. A total of 705 elementary school students, 347 girls and 358 boys took part in the study. They were chosen evenly from the Seoul metropolitan areas, provincial cities, or rural areas, and were asked to fill out a questionnaire. The questionnaire was categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The average height, weight, body mass index, and Rohrer index were 143.2 cm, 37.6 kg, 18.2 and 127.2 respectively. A significant number of children(39.2%) answered their bed time was between 11 and 12 pm. Only 28.3% answered that the whole family has breakfast together, and 47.7% have dinner together. A considerable number of children, 17.8% for breakfast and 6.9% for dinner, answered they eat alone. Most of the children answered they like to have dinner with the whole family. Half of the children answered they do not feel hungry before having breakfast. Proportions of children for their favorite meal time were 66.8%, and 25.4% and 7.8% for dinner, school lunch, and breakfast respectively. The largest proportions of children, 53.3% and 68.7%, have breakfast and dinner at home. Most of the children(75.2%) never purchase their dinner. Forty two% of the children answered they like school lunch, however, 60% of children answered they leave portions of lunch uneaten occasionally or always. Only 38.0% and 46.2% of the children have nutritionally adequate diet for breakfast and dinner. Children having more meals with the whole family possessed a more positive attitude towards breakfast compared to the children who eat with the whole family less frequently. In conclusion, Korea children are exposed to different health threatening food ecology problems related to changing environments, and consistent concern and support from community nutritionists are required.

Adrenal cysts are rare lesion that usually present themselves as an incidental finding during surgery, or at the time of autopsy. The cysts are usually small, seldom exceeding 10cm in diameter, and are generally asymptomatic. However, they present a difficult problem in differentiation between benign and malignant lesions of the adrenal gland. In the differential diagnosis, other cystic lesions of the upper abdomen must also be considered, including hepatic, splenic, renal and pancreatic cysts. Herein we report a case of endothelial cyst of lymphangiomatous type of the adrenal gland which was detected in a 44-year-old male patient during a routine health examination by ultrasonography as a pancreatic pseudocyst. Gross examination revealed multiple separate but continuous cysts, measuring 10.6x8x7cm in dimension. Within the wall, compressed adrenal cortex was noted. Microscopically, fibrous wall containing hypertrophied smooth muscle lined by endothelial cells was also noted. We reviewed literatures of the adrenal cyst and report a case.

PURPOSE: Understanding changes in pathogen and pneumonia prevalence among pediatric pneumonia patients is important for the prevention of infectious diseases. METHODS: We retrospectively analyzed data of children younger than 18 years diagnosed with pneumonia at 117 Emergency Departments in Korea between 2007 and 2014. RESULTS: Over the study period, 329,380 pediatric cases of pneumonia were identified. The most frequent age group was 1–3 years old (48.6%) and the next was less than 12 months of age (17.4%). Based on International Classification of Diseases, 10th revision diagnostic codes, confirmed cases of viral pneumonia comprised 8.4% of all cases, pneumonia due to Mycoplasma pneumoniae comprised 3.8% and confirmed cases of bacterial pneumonia 1.3%. The prevalence of confirmed bacterial pneumonia decreased from 3.07% in 2007 and 4.01% in 2008 to 0.65% in 2014. The yearly rate of pneumococcal pneumonia also decreased from 0.47% in 2007 to 0.08% in 2014. A periodic prevalence of M. pneumoniae pneumonia (MP) was identified. CONCLUSION: The increased number of patients with pneumonia, bacterial pneumonia, pleural effusion, and empyema in 2011 and 2013–2014 resulted from an MP epidemic. We provide evidence that the frequency of confirmed cases of bacterial pneumonia and pneumococcal pneumonia has declined from 2007 to 2014, which can simultaneously reflect the effectiveness of the pneumococcal conjugate vaccine.

Dehumidifying agents are commonly used to remove moisture and odors and are not meant for oral ingestion. The hazards of accidental oral ingestion of dehumidifying agents are not well known. A 31-year-old man with autism drank the liquid desiccant contained in the barrel of a dehumidifier while sleepwalking. The desiccant mainly consisted of calcium chloride. He was taken to the emergency center with persistent vomiting and underwent gastric lavage. The patient was treated for hypercalcemia due to calcium chloride poisoning. He eventually died of multiple organ failure. Autopsy findings were as follows: acute suppurative pneumonia, intra-abdominal inflammation, liver necrosis, acute pancreatitis, and gastrointestinal hemorrhage. Calcium chloride has relatively low toxicity; however, when ingested orally, it can cause severe internal damage, and even death. We suggest active preventive measures to ensure the safe use of dehumidifying agents.

Sequence information from the ribosomal RNA molecule can be used as a molecular clock. Therefore, 16S rRNA sequences have become a widely used tool in bacterial systematics, bacterial typing and studies of the composition of micro-organisms in environmental samples. Consequently, the databases are continuously updated with new 16S rRNA sequence information from different species. This in turn facilitates the identification of new isolates, which is important for the diagnosis of various infectious diseases in research. To development differential identification technique in the Yersinia species, the 16S rDNA for total 17 serotypes of Y. pseudotuberculosis type strains and one of Y. enterocolitica wild strain were amplified by polymerase chain reaction and cloned into pGEM-T vector, partially sequenced and analyzed. The 16S rDNA nucleotide sequence homologies among Yersinia strains were ranged 100% to 93.6%. Phylogenetic tree generated from 16S rDNA sequencing data showed different phyletic line that could be readily separated from each serotypes and other enteric bacterium.

BACKGROUND: Bacterial vaginitis (BV) and Trichomonas vaginitis are the most frequently recurring infectious diseases in women. Therefore, accurate tests for post-treatment follow-up are required. A multiplex PCR assay allows for the simultaneous detection of multiple pathogens in a single specimen. In this study, we assessed the clinical implications of multiplex PCR detection of fastidious microorganisms causing vaginitis. METHODS: A total of 216 vaginitis patients who presented to Chung-Ang University Yongsan Hospital with more than one positive result on multiplex PCR (Trichomonas vaginalis (TV), Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), Ureaplasma urealyticum (UU), Mycoplasma genitalium (MG), Mycoplasma hominis (MH)) were retrospectively enrolled in this study. Each patient's clinical symptoms, initial treatment and follow-up for BV, and other related test results were also retrospectively reviewed. RESULTS: The most commonly reported symptom was abnormal discharge, followed by pruritis (73.1%), lower abdominal pain (38.4%), urination difficulties (13%), and others such as fever. According to the multiplex PCR results, there were 116 cases (35.8%) of MH, 86 cases (26.5%) of UU, 62 cases (19.1%) of CT, and 84 cases (38.9%) were mixed infections. Among those patients with single infections, treatment changed for 63 cases (65.6%) while treatment remained unchanged for 17 (17.7%) after PCR results were reported. CONCLUSION: The diagnosis of BV using multiplex PCR is clinically effective and the results of which can be incorporated in antibiotic selection for patients with multiple sexually transmitted diseases (STD). Multiplex PCR may be especially helpful in the diagnosis of patients in whom the differentiation of STD pathogens is difficult using traditional methods.

Candidemia due to uncommon Candida spp. appears to be increasing in incidence. C. dubliniensis has been increasingly recovered from individuals not infected with HIV. Identification of C. dubliniensis can be problematic in routine clinical practice due to its phenotypic resemblance to C. albicans. We report the first case of C. dubliniensis candidemia in Korea, which occurred in a 64-yr-old woman who presented with partial seizure, drowsiness, and recurrent fever. Germ-tube positive yeast that was isolated from blood and central venous catheter tip cultures formed smooth, white colonies on sheep blood agar and Sabouraud agar plates, indicative of Candida spp. C. dubliniensis was identified using the Vitek 2 system (bioMerieux, USA), latex agglutination, chromogenic agar, and multiplex PCR. The blood isolate was susceptible to flucytosine, fluconazole, voriconazole, and amphotericin B. After removal of the central venous catheter and initiation of fluconazole treatment, the patient's condition gradually improved, and she was cleared for discharge from our hospital. Both clinicians and microbiologists should be aware of predisposing factors to C. dubliniensis candidemia in order to promote early diagnosis and appropriate treatment.
