Pathologists and others have been calling the serous cystadenoma of the pancreas "microcystic cystadenoma", following Compagno and Oertel's proposal in l978 because it usually consists of innumerable small cysts (less than 2cm). However, unilocular or predominantly macrocystic types of serous cystadenoma have been occasionally reported. Therefore, they present a difficulty in precise preoperative and intraoperative diagnosis for their simi1ar gross appearance to other cystic lesions of the pancreas. We discovered two cases of macrocystic and unilocular serous cystadenomas of the pancreas which were lined by cuboidal to flattened epithelial cells. They contained PAS positive and D-PAS negative intracytoplasmic glycogen granules. The unilocular, macrocystic and microcystic patterns may represent a morphologic spectrum of a pancreatic neoplasm. So we propose to use the term "serous cystadenoma" rather than microcystic cystadenoma.

BACKGROUND: Many anesthesiolosists feel that epidural anesthesia is unsuitable for spinal sugery. However, several articles have been published in which epidural anesthesia is viewed as a good alternative to general anesthesia for spine surgery. The aim of this study was to evaluate effectiveness and complications of epidural anesthesia for spine surgery. METHODS: Eighty-two patients undergoing epidural anesthesia for spine surgery was studied prospectively. Epidural anesthesia was performed using 18-gauge Tuohy needles inserted at the L1-2 interspace. A test dose of lidocaine 3 ml was injected to check for a subarachnoid puncture. After a 2 - 3 minute waiting period, 0.5% bupivacaine 12 ml was slowly injected for 3 minutes. The pain at the operation site and roots, extension of anesthesia, motor blockade and complications were evaluated. RESULTS: Pain at the operation site was minimal in 83% of the patients; however, 44% of the patients complained of moderate to severe root pain. No patient had a new neurologic deficit as a result of the epidural technique. Perioperative complications were minimal and could be easily treated. CONCLUSIONS: We concluded that proper administration of epidural anesthesia for spine surgery is a safe and reliable procedure and a good alternative to general anesthesia.

PURPOSE: This study reviewed articles related to breast cancer, cognitive function and chemotherapy available in 4 databases. METHODS: The researcher reviewed 32 pieces of literature that were published between January 2001 and November 2011. RESULTS: Within the last decade, several studies have investigated whether adjuvant treatment of breast cancer affects cognitive function. A number of prospective studies have reported inconsistent results regarding whether chemotherapy affects cognitive function. Approximately half of the studies reported subtle cognitive decline in a wide range of domains among some breast cancer patients following chemotherapy, and others did not. CONCLUSION: Breast cancer patients receiving adjuvant chemotherapy showed the most deterioration and the most persistent decline in cognitive function. Since cognitive impairment is subtle, if evident at all, discrepant findings are due to hormonal, physiological, psychological or temporal confounding variables and differences in study design. Especially, that chemotherapy may impair memory, executive function, attention and visuospatial function in women with breast cancer.

Our previous work has identified miR-125b as a negative regulator of melanogenesis. However, the specific melanogenesis-related genes targeted by this miRNA had not been identified. In this study, we established a screening strategy involving three consecutive analytical approaches—analysis of target genes of miR-125b, expression correlation analysis between each target gene and representative pigmentary genes, and functional analysis of candidate genes related to melanogenesis—to discover melanogenesis-related genes targeted by miR-125b. Through these analyses, we identified SRC homology 3 domain-binding protein 4 (SH3BP4) as a novel pigmentation gene. In addition, by combining bioinformatics analysis and experimental validation, we demonstrated that SH3BP4 is a direct target of miR-125b. Finally, we found that SH3BP4 is transcriptionally regulated by microphthalmia-associated transcription factor as its direct target. These findings provide important insights into the roles of miRNAs and their targets in melanogenesis.

PURPOSE: Many studies showed that the asthmatic children mostly have psychosocial problem such as depression or anxiety. The object of this study is to help the asthmatic children and their family by knowing what is their mothers' biggest concern about their asthmatic children. METHODS: We made up a questionnaire with asked the mothers by telephone. If they though asthma had a certain effect on their asthmatic children's activity, depression, anxiety, positiveness, scholastic achievement, friendship, pleasure, concentration, anger, growth and development. We asked the mothers whose children had visited the pediatric department in st. colomban's hospital from 1990 to 1996 and had been diagnosed and treated as asthma, and whose asthmatic children were between 7 and 21. RESULTS: More than half of the mothers who got a phone-call said that their children had problems in house life, school life, social life due to asthma and frequent asthmatic attack made their children less concentrated, inactive, less scholastic achieved, but there were few who said that asthma seemed to have an effect on their children's friendship, depression, pleasure. CONCLUSIONS: In the psychological aspect, the mothers may concern more if their children cannot keep up with the competitive social tendency closely related to concentration and scholastic achievement than if their children have some emotional disorder or behavial disorder such as depression and anxiety

BACKGROUND: In developed countries, food-born diseases have decreased and hospital laboratory have taken more simple method rather than complex enrichment-selective methods. But detection rate of pathogenic bacteria in stool culture was not so high. METHODS: We mixed 4 pathogenic bacteria (S. typhi, S. flexneri, V. cholerae and Y. enterocolitica) with 3 stool specimens from healthy persons (for Y. enterocolitica, 5 specimens) and innoculated directly or after enrichment (105 bacteria/plate). After proper incubation, we counted suspected colonies and calculated true positive rate after identification of each colonies. RESULTS: For S. typhi, in the case of direct innoculation on the MacConkey, XLD and SS agar, positive rate of selected colonies were below 36.6%. After enrichment in SF broth for 8 hours, the rate were 80.0%, 83.0% and 70.0% respectively. For S. flexneri, the rates were 86.7%, 100%, 93.3% in direct innoculation, and were highest after enrichment in GN broth for two hours (93.3% in MacConkey and 100.0% in both XLD and SS agar). For V. cholerae, inspite of screening by catalase and oxidase tests, positive rate of selected colonies were 0% (0/7 colonies) in direct innoculation on the MacConkey. After enrichment in APW about 1 day and on TCBS agar, the rate were 100%. For Y. enterocolitica, after incubation at room temperature for 2 days, most selected colonies were Y. enterocolitica on CIN media. CONCLUSION: For more efficient detection of pathogenic bacteria in stool culture, combination of direct innoculation on MacConkey agar and on one or two selective media after proper enrichment process, should be considered.

OBJECTIVE: To determine whether polymorphisms of the Vitamin D receptor (VDR)gene,known to be associated with osteoporosis and/or osteoarthritis (OA) in Caucasians,might also relate to the risk of OA and osteoporosis in Korean postmenopausal women METHODS: A population of 130 postmenopausal women,including 76 healthy controls and 54 knee OA patients,were studied using anteroposterior radiographs of the knee,which were graded for OA according to the Kellgren classification system.The VDR genotype was determined by using polymerase chain reaction and by digestion with the three restriction enzymes Taq I,Bsm I,and Apa I.Femoral neck bone mineral density (BMD)was assessed in all participants by dual energy X-ray absorptiometry . RESULTS: VDR genotype frequency distributions in Koreans were much different from Caucasian's both in the OA group and the control group.Especially, "t t", "B B" and "A A" genotype were very rare,prominently differentiating from Caucasians.But within Koreans,no significant differences in VDR genotype frequencies were observed between OA cases and controls.VDR genotype was not significantly associated with the radiographic grades of OA.And there were no significant relationships of VDR genotype with BMD scores in each group. CONCLUSION: In Korean postmenoposal women,the VDR gene polymorphisms do not significantly contribute to an increased prevalence of knee OA or to differences in BMD.VDR genotype analysis would not be helpful for assessing the risk of knee OA in Koreans because :(1)there is no correlation of VDR genotypes with the radiographic severity of OA ;and (2)there is a more skewed distribution of VDR genotypes in Korean population compared to the Caucasian's .

PURPOSE: In dental clinical fields, various periodontal membranes are currently used for periodontal regeneration. The periodontal membranes are categorized into two basic types: resorbable and non-resorbable. According to the case, clinician select which membrane is used. Comparing different membranes that are generally used in clinic is meaningful. For this purpose, this study evaluates histological effects of various membranes in canine one wall intrabony defect models and it suggest a valuation basis about study model. MATERIAL AND METHOD: The membranes were non-resorbable TefGen Plus(R), resorbable Gore Resolut XT(R) and resorbable Osteoguide(R). One wall intrabony defects were surgically created at the second and the mesial aspect of the fourth mandibular premolars in either right or left jaw quadrants in two dogs. The animals were euthanized 8 weeks post-surgery when block sections of the defect sites were collected and prepared for histological evaluation. RESULTS: 1. While infiltration of inflammatory cells were observed in control, TefGen Plus(R) and Gore Resolut XT(R), it was not observed in Osteoguide(R). 2. TefGen Plus(R) had higher integrity than others and Osteoguide(R) was absorbed with folding shape. Gore Resolut XT(R) was divided everal parts during resorbtion and it was also absorbed from inside. 3. Quantity of new bone and new cementum was not abundant in all membranes. 4. For histologic evaluation of membranes we should consider infiltration of inflammatory, migration of junctional epithelium, integrity of membrane, quantity of new bone and new cementum, connective tissue formation and aspect of resorption. CONCLUSION: This histologic evaluation suggests that Osteoguide(R) provides periodontal regenerative environment with less inflammatory state. It is meangful that this study model suggests a valuation basis about other study model.

We report the case of a patient with primary renal amyloidosis, who was progressed to fulminant hepatic failure. A 68-year-old man visited our hospital for evaluation of anorexia, weight loss and hepatomegaly. Laboratory examination revealed proteinuria and azotemia. He was confirmed to have primary amyloidosis by renal biopsy. His renal function progressed to deteriorate rapidly with marked deterioration of liver function with cholestasis. Peritoneal dialysis and steroid therapy were started for reduction of urine output and rapid progression of azotemia, and aggravation of liver function. Azotemia was improved after peritoneal dialysis but the liver function worsened leading to hepatic failure, causing death. If jaundice has progressed in any patients with primary amyloidosis, liver transplantation and stem cell transplantation should be considered for preparation of hepatic failure.
