Fungal contamination of built-in furniture is a frequent problem in Korea when new apartment is built. However, domestic information on the contaminating fungi is very limited. This study was conducted to isolate, identify and characterize the fungi of the problem in one of the apartment houses where the fungi were claimed in the built-in furniture before the house owner moves in. Fungi present in the furniture installed in a main room, dress room, and kitchen side were visually and microscopically confirmed and purely isolated on PDA. The isolated fungi were identified by analyzing the morphological characteristics and nucleotide sequence of the ITS, calmodulin gene, and TEF-1α gene. Aspergillus creber, A. niger, A. pseudoglacus, A. ruber, Cladosporium perangustum and Penicillium commune were identified. Four out of the six fungal species were positive for at least one enzyme in six kinds of extracellular enzyme assays. When these four species (A. creber, A. niger, C. perangustum and P. commune) were inoculated onto four kinds of wood chips of furniture materials, they were able to colonize all of the wood chips. Their settlement was better at 95% humidity condition than at 30% humidity condition. Among the four species, C. perangustum caused the darkest discoloration and secreted the most number of extracellular enzymes. The four species were re-isolated from the colonized wood chips and confirmed as the problematic fungi in the built-in furniture.

PURPOSE: Gastric variceal bleeding in cirrhotic patient is an emergent, life threatening disease of which the adequate treatment is still in dispute. The periesophagogastric devascularization (PD) would be the alternative operative procedure. The aim of this study is to evaluate the safety and long-term results of PD for the gastric fundal variceal bleeding. METHODS: A retrospective analysis was made of fifty-two patients with gastric variceal bleeding who underwent PD with or without fundectomy from August 1994 to March 2006. We evaluated the clinical characteristics, operative morbidity, mortality and long-term follow up results. RESULTS: The operative morbidity was 34.9% and overall mortality was 17.3%. The Child-Pugh classification at operation, the number of previous varix bleeding episode, the success of preoperative intervention, splenectomy, esophageal transection, and ongoing bleeding at operation had a significant effect on postoperative mortality. Most common cause of postoperative death was hepatic failure. Child-Pugh classification and esophageal transection were significant risk factor for postoperative mortality comparing before and after year 2001. During the mean follow-up period of 33.58+/-27.08 months, there was no recurrent bleeding from gastric varices. The cumulative 5-year survival rate was 64.1%. 0f 14 patients deceased, 6 patients died of hepatocellular carcinoma. Not only there was no death caused by recurrent variceal bleeding, but there was no recurrent gastric variceal bleeding. Hepatic functional reserve and concomitant hepatocellular carcinoma were the most important prognostic factors in the long term survival by multiple regression analysis. CONCLUSION: We concluded that PD reached both low postoperative mortality and recurrent bleeding rate with good long-term survival. So it could be one of the most effective treatment for the gastric fundal variceal bleeding.

PURPOSE: The goal of this study was to compare the efficacy of oral 25% dextrose treatment or/and pacifier for analgesia in healthy newborns during intramuscular injection of a hepatitis B vaccine. METHODS: A prospective, randomized, partially blinded, clinical trial was performed in 132 healthy newborns. They were assigned randomly to 4 treatment groups: control group (2 mL distilled water), dextrose group (2 mL 25% dextrose), pacifier group, dextrose+ pacifier group (pacifier coating with 25% dextrose) during intramuscular injection of hepatitis B vaccine. For all groups, Neonatal Infant Pain Scale (NIPS), Neonatal Facial Coding System (NFCS), Premature Infant Pain Profile (PIPP) scores were evaluated before the injection, during the injection, and at 2 minutes after the injection. Pain scores were compared among the 4 groups. RESULTS: Maternal and neonatal characteristics were similar among the 4 groups. 25% dextrose treatment led to lower NIPS pain scores during injection (6.4+/-0.9 vs. 5.5+/-1.7, P=0.01) and after injection (1.6+/-2.0 vs. 0.6+/-0.9, P=0.01) and NFCS pain scores after injection (1.5+/-2.3 vs. 0.7+/-0.8, P=0.04) than control group. The number of neonates who feel the pain (indication of scores: NIPS> or =4, NFCS> or =3) decreased (9 (23.1%) vs. 0 (0%), P=0.04 via NIPS, 7 (17.9%) vs. 0 (0%), P=0.02 via NFCS). However, all treatment groups did not decreased PIPP scores, compared with the control group. CONCLUSION: Oral 25% dextrose is effective than distilled water or using pacifier with or without 25% dextrose in reducing pain during intramuscular injection of hepatitis B vaccinations. Further study based on this preliminary study need about nonpharmacologic management of pain in newborns.

OBJECTIVES: Despite severe oligospermia, males with Y chromosome microdeletion can achieve conception through ICSI (Intracytoplasmic Sperm Injection). However, ICSI may not only result in the transmission of microdeletions but also the expansion of deletion to the offspring. The purpose of this study was to screen vertical transmission, expansion of microdeletions and de novo deletion in male fetuses conceived by ICSI. MATERIALS AND METHODS: A total of 32 ICSI treated patients with their 33 (a case of twin) male fetuses conceived by ICSI were used to make this study group. Sequence-tagged sites (STSs)-based PCR analyses were performed on genomic DNA isolated from peripheral blood of fathers and from the amniocytes of male fetuses. Ten primer pairs namely, sY134, sY138, MK5, sY152, sY147, sY254, sY255, SPGY1, sY269 and sY158 were used. The samples with deletions were verified at least three times. RESULTS: We detected a frequency of 12.5% (4 of the 32 patients) of microdeletions in ICSI patients. In 4 patients with detected deletions, two patients have proven deletions on single STS marker and their male fetuses have the identical deletion in this region. Another two patients have two and three deletions, but their male fetuses have more than 3 deletions which include deletions to their father's. Meanwhile, seven male fetuses, whose fathers were analyzed to have all 10 STS markers present, have deletions present in at least one or more of the markers. CONCLUSIONS: Although the majority of deletions on the Y chromosome are believed to arise de novo, in some cases a deletion has been transmitted from the fertile father to the infertile patient. In other cases the deletion was transmitted through ICSI treatment, it is likely that one sperm cell is injected through the oocyte's cytoplasm and fertilization can be obtained from spermatozoa. Our tests for deletion were determined by PCR and our results show that the ICSI treatment may lead to vertical transmission, expansion and de novo Y chromosome microdeletions in male fetuses. Because the sample group was relatively small, one should be cautious in analyzing these data. However, it is important to counsel infertile couples contemplating ICSI if the male carries Y chromosomal microdeletions.

OBJECTIVE: The aim of this study was to evaluate the association between a variable number of tandem repeats polymorphism at the dopamine D4 receptor gene (DRD4) and the performance of children with attention deficit hyperactivity disorder (ADHD) in a continuous performance test (CPT). METHODS: This study included 72 ADHD children (mean age=9.39+/-2.05 years) who were recruited from one child psychiatric clinic. The omission errors, commission errors, reaction time and reaction standardization in the CPT were computed. The number of 48-base pairs tandem repeats in the exon III of DRD4 was analyzed in a blind manner. RESULTS: The homozygosity of the 4-repeat allele at DRD4 was significantly associated with fewer commission errors (t=2.364, df=28.685, p=0.025) and standard deviation of reaction time (t=2.351, df=24.648, p=0.027) even after adjusting for age. The results of analyses of CPT measured values among three groups showed that the group with higher frequency of the 4-repeat allele showed a lower mean score of commission errors (F=4.268, df=2, p=0.018). CONCLUSION: These results suggest a protective role of 4-repeat allele of the DRD4 polymorphisms on commission errors in the CPT in children with ADHD.

OBJECTIVES: This study was designed to assess the relationship between alcohol use and stress. METHODS: The study subjects were 1,261 people who drink among the 2,565 people who lived in Gangneung. We investigated the sociodemographic characteristics, Short Form-12 (SF-12), Global Assessment of Recent Stress (GARS) and Alcohol Use Disorder Identification Test (AUDIT). RESULTS: In Problem drinking group the GARS was significantly positively associated with the AUDIT (p=0.02). In Social drinking group sex (p<0.001) and age (p=0.02) is significantly associated with the AUDIT. CONCLUSION: This study showed the significantly positively association between stress and alcohol use. We think that the intervention and active management of the stress can prevent the alcohol problem.

Human mouth environment is known to include a variety bacteria, including Streptococcus spp., Staphylococcus spp., Actinomyces spp., Lactobacillus spp., Candida spp., Enterobacteriaceae, et al. Human oral microorganisms can cause dental caries, gingivitis, periodontitis, respiratory tract infection, and cardiovascular disease. Thus, right denture cleaning is essential to oral and general human health. The aim of this study was to evaluate the bactericidal effect of a sodium dichloroisocyanurate-based effervescent tablet (Aos Denti Germ, Aos Company, Chungbuk, Korea) against oral microorganisms. A total of 5 species Streptococcus spp. (Streptococcus anginosus, Streptococcus mitis, Streptococcus mutans, Streptococcus oralis, and Streptococcus sobrinus), Actinomyces oris, Candida albicans, and Escherichia coli were used in this study. All strains were exposed to the distilled water prepared with effervescent tablet. After the exposure, the mixture of strains and effervescent tablet was inoculated onto blood agar or MacConkey agar plate and cultured at 36℃. All strains were killed immediately on exposure to effervescent tablet. The results suggested that effervescent tablet could be used as an effective denture cleanser for dental hygiene.

OBJECTIVE: Obsessive-compulsive disorder (OCD) is a clinically heterogeneous disorder with a bimodal pattern in age onset and treatment outcomes. This study attempted to ascertain the importance of the age factor for a better phenotypic precision. Therefore, the authors compared adult OCD patients with an early symptom onset to adult OCD patients with a later symptom onset. METHODS: One hundred sixty five patients with OCD were evaluated with semistructured interviews;79 with symptom onset before the age of 17 (early onset group) and 86 with symptom onset after the age of 17 (late onset group). The two groups were analyzed in terms of Y-BOCS (Yale-Brown Obsessive Compulsive Scale) scores and demographic data including clinical variables. RESULTS: Early onset group has more comorbidity of tic disorder and lesser of depression and anxiety disorder than late onset group. Early onset group showed more family history of tic disorder than late onset group. The treatment response to SSRI is relatively declined after 18 months of initiation in early onset group. CONCLUSION: The results indicate that age at onset may be an important factor in subtyping OCD. Early onset group may have more biological and familial tendency that might be differentiate the two groups.
