In order to overcome a certain disease, it is necessary to confirm the prevalence, natural course and risk factors of the disease. The Korean Academy of Pediatric Allergy and Respiratory Disease has become the mainstream and has been paying a great deal of attention to the epidemiologic research of allergic diseases in Korean children since 1995. In this review, we would like to summarize the International Study of Asthma and Allergies in Childhood epidemiology study in Korea, the cohort study for allergic diseases, and the national medical big data. New epidemiological studies are needed to clarify the relationships between allergic diseases and factors such as air pollution, climate changes, microbiome, and diet, which are likely to be new risk factors for allergic diseases. Based on these epidemiological studies, we hope to find ways to overcome pediatric allergic diseases in Korea and also to share epidemiologic techniques and manpower.

This study was conducted to investigate the supplementary effects of Lentinus edodes on blood pressure and blood lipid levels in the Hypertensive Rat. We supplied 3 kinds of experimental diets (Control; CO, cap of Lentinus edodes; LC, and stipe of Lentinus edodes; LS) to spontaneously hypertensive rats (SHR) for 8 weeks. Diet intake, body weight, organ weights, and serum lipid levels were measured. There was no significant difference in diet intake, and body, liver and epididymal fat pad weights among experimental groups. The levels of systolic and diastolic blood pressure were significantly lower in LC and LS groups than CO group. The concentrations of serum total cholesterol were lower in LC and LS groups than CO group. These results suggested that Lentinus edodes decrease blood pressure levels and serum total cholesterol concentration in the spontaneously hypertensive rats. But these effects of Lentinus edodes didn't show any significant difference between animals fed cap and stipe of this mushroom.

Gastric sarcoidosis is a rare disease accounting for 0.1~0.9% of all sarcoidosis cases. It presents either as a systemic disease or as an isolated finding. Diagnosis is established with biopsy of a lesion. It is important to distinguish between sarcoidosis and a sarcoid-like reaction, which can be caused by Crohn's disease, foreign body reaction, fungal infection, tuberculosis, or malignancy. We report a 60-year-old woman with both gastric and pulmonary sarcoidosis.

BACKGROUND: The aim of this study is to evaluate the status and adverse events of anesthesiologist-administered sedation and general anesthesia, outside of the operating room. METHODS: Patients undergoing sedation and general anesthesia, outside of the operating room, were retrospectively reviewed, during the study period from March to October of 2011. The patient's characteristics, primary diagnosis for the procedure, procedures performed outside of the operating room, adverse events associated with sedation and anesthesia, sedatives/anesthetic agents, and anesthetic time, were all assessed. RESULTS: A total of 429 patient's submitted data on 44 sedation/401 general anesthesia were encountered, during the study period. The range of age varied from 2 months to 83 yrs. Most common primary diagnosis for the procedure, during sedation or general anesthesia, was vascular or neurologic problem, respectively. The most frequently used sedatives or analgesics were propofol alone, during sedation (45%) and propofol with remifentanil, during general anesthesia (60%), respectively. Adverse events occurred in 32%, during sedation and 29%, during general anesthesia. Bradycardia occurred in 16% of sedation and hypotension occurred in 15% of general anesthesia. CONCLUSIONS: Our data suggest that the sedation/general anesthesia for procedures, outside of the operating room, have been performed in a complex situation, various location, and wide age groups. Adequate monitoring, sufficient anesthesia support, including skilled staff and emergency equipments, and appropriate drug for each procedure are needed for the patient's safety.

PURPOSE: Accurate testing for estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) is essential for breast cancer treatment. At present, immunohistochemistry (IHC)/florescence in situ hybridization (FISH) are widely accepted as the standard testing methods. To investigate the value of NanoString nCounter®, we performed its comparative analysis with IHC/FISH and real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) for the assessment of ER, PR, and HER2. METHODS: Data on IHC/FISH results for ER, PR, and HER2 in 240 patients from a single tertiary hospital in Korea were collected and compared with NanoString nCounter® and qRT-PCR results at a single institution. RESULTS: Expression levels for each gene using NanoString nCounter® showed good correlation with the corresponding data for protein expression by IHC (p<0.001) and gene amplification status for HER2 (p<0.001). Comparisons between gene expression and IHC data showed good overall agreement with a high area under the curve (AUC) for ESR1/ER (AUC=0.939), PgR/PR (AUC=0.796), and HER2/HER2 (AUC=0.989) (p<0.001). CONCLUSION: The quantification of ER, PgR, and HER2 mRNA expression with NanoString nCounter® may be a viable alternative to conventional IHC/FISH methods.

PURPOSE: Purpose of this study was to determine if quantitative measures of CT attenuation and ADC values in combination with conventional imaging features can differentiate primary central nervous system lymphoma (PCNSL) and glioblastoma (GBM). MATERIALS AND METHODS: Twenty-six patients with histologically-proven GBM (14 men and 12 women; median age, 50 years; age range, 22 - 73 years) and 14 patients with PCNSL (11 men and 3 women; median age, 61 years; age range, 41 - 74 years) were enrolled. Maximum CT attenuation, minimum ADC, and lesion to normal parenchyma minimum ADC ratios were measured in solid tumor regions. Conventional imaging features were evaluated for the following: ill-defined margin, homogeneous enhancement pattern, degree of necrosis, extent of tumor involvement and multiplicity. The Mann-Whitney test was used to compare maximum CT attenuation and minimum ADC values for PCNSL and GBM. Fisher's exact test was used to evaluate relationships between pathologic diagnoses and imaging features. RESULTS: The CT attenuations were similar for PCNSL and GBM (37.84 +/- 6.90 HU versus 37.00 +/- 5.54 HU, p = 0.68), but minimum ADC and minimum ADC ratio were significant lower in PCNSL than in GBM (595.01 +/- 228.28 10(-6) mm2/s versus 736.52 +/- 162.05 10(-6) mm2/s; p = 0.028, 0.87 +/- 0.26 versus 1.14 +/- 0.29; p = 0.007). PCNSL showed greater homogeneous enhancement and smaller necrotic areas than GBM (p = 0.003 and p < 0.001, respectively) and was more likely to have multiple tumors than GBM (p = 0.039). When necrotic PCNSL (n = 4) and necrotic GBM (n = 24) were compared, minimum ADC and minimum ADC ratios were also significantly lower in PCNSL, but CT attenuation were not. CONCLUSION: Although CT attenuation does not provide valuable information, minimum ADC and minimum ADC ratio and some imaging features can aid the differentiation of PCNSL and GBM.

We report a case of primary penile undifferentiated sarcoma. A 16-year-old adolescent man visited Pusan National University Hospital complaining of a painless mass on his penis that was increasing in size. Magnetic resonance images revealed a 5x5-cm mass and pathological examinations revealed small round cell sarcomas with neuroendocrine differentiation. The tumor, which had metastatic pulmonary nodules, was treated by tumorectomy and systemic chemotherapy. Thirty-four months after the initial diagnosis, the patient was still alive without evidence of local recurrence or metastatic disease. This is our second case of an undifferentiated penile sarcoma.

OBJECTIVE: The validity of olfactory bulbectomized rat as an animal depression model and the possibilities of the NMDA antagonist as an antidepressant would be evaluated by demonstrating structural alterations in their brain MRIs and histological findings of hippocampus. METHODS: Those 8-week old male Sprague-Dawley rats received either an olfactory bulbectomy or sham operation and volume changes at ventricles and caudate nucleus in their brain MRI were acquired at preoperation and postoperation. Those olfactory bulbectomized rats received either memantine, an uncompetitive NMDA antagonist, or normal saline, a placebo, and their brain structural changes in MRI were acquired. At preoperation, postoperation, and postmedication each one of the rats with sham-operation, with memantine, and with placebo was sacrificed to acquire histological impressions. RESULTS: 1) Comparison of the volume changes between preoperation and postoperation showed statistical significance; the volumes of the left and right lateral ventricles (p=0.007, p=0.008) and the third ventricle (p=0.003) increased significantly but the volumes of left and right caudate nucleus decreased (p=0.014, p=0.032), compared to that of the controls. 2) After 6-weeks of memantine administrations, the OB rats revealed more definite recovery in brain MRIs statistically than the controls: the volumes of left and right ventricles and left and right caudate nucleus (p=0.004, p=0.03 ; p=0.04, p=0.05). 3) The hippocampus histological findings of the olfactory bulbectomy showed frequently eosinophilic cytoplasm and hyperchromatic nucleus with shrinkage in CA3. After memantine intake, the hippocampus histological findings returned to nearly normal and showed mixtures of normal cell and abnormal neuron cell. CONCLUSION: The OB models would be valid as an animal model of depression and alterations in their brain MRI images after administrations of NMDA antagonist could be an indicator of antidepressant effects.

STATEMENT OF PROBLEM: Streptococcus produces energy and forms extracellular polysaccharides by metabolizing sucrose. Insoluble glucan, a kind of extracellular polysaccharide, is the important material of dental plaque. Fructose affects the metabolism of sucrose. PURPOSE: The purpose of this study was to evaluate the effect of fructose on the metabolism of sucrose in Streptococcus mutans. MATERIALS AND METHODS: To determine the effect of fructose on the formation of artificial plaque by Streptococcus mutans Ingbritt, S. mutansand fructose were placed in beakers containing M17 broth and sucrose. The wires were hung on frameworks inserted into cork stoppers, and then immersed in each of the beakers. After the incubation with gentle shaking, each wire was weighed. To analyze the effect of fructose on the sucrose metabolism by S. mutans or glucosyltransferase, S. mutans and fructose were placed in M17 broth containing sucrose. After the incubation. the remaining sucrose and polymers were analysed by thin layer chromatography. RESULTS: The following results were obtained; 1. When Streptococcus mutans was cultured in the media containing 3% sucrose for 8 hours, the mean weight of formed artificial plaque on the wires was 124.3+/-3.0 mg, whereas being reduced to 20.7+/-10.2 mg in the media added with 3% sucrose and 4% fructose(p<0.05). 2. When the control containing glucose was added with sucrose, the optical density of Streptococcus mutans solution cultured for 24 hours was not increased compared with the control, while being increased by adding with fructose. 3. When Streptococcus mutanswas incubated in the media added with sucrose and fructose for 8 hours, the number of viable cells was increased compared with the media added with sucrose. 4. The amount of remained sucrose was increased in Streptococcus mutansculture supernatant of media added with sucrose and fructose than with sucrose only, but the amount of produced insoluble glucan was decreased. 5. The amounts of remained sucrose and produced soluble glucan were increased in the culture of glucosyltransferase-contained media added with sucrose and fructose than with sucrose only, but the amount of produced insoluble glucan was decreased. CONCLUSION: These results indicated that the sucrose metabolism and the production of insoluble glucan were inhibited in Streptococcus mutans by adding fructose in the media containing sucrose.
