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.

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.

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

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 .

Though the development of immunosuppressive agents has increased the survival rate of transplanted kidneys, the opportunistic infection has increased in transplant recipients. Aspergillus may cause invasive aspergillosis via sino-pulmonary route in immunocompromized patients. We report a rare case of invasive aspergillosis of a transplanted kidney without having disseminated disease. A 41 year-old female, who underwent cadaveric renal transplantation 10 months ago, presented with diarrhea and anemia. Ultrasound examination and CT scan revealed an abscess lesion in the transplanted kidney. Surgical curettage and percutaneous drainage were performed. Because, microscopic examination demonstrated fungal hyphae consistent with Aspergillus species, antifungal agents were prescribed. Later, partial transplant nephrectomy and embolization of the remnant kidney were performed.

The purpose of this study was to measure the thickness of masticatory mucosa in the hard palate as a donor site for mucogingival surgery by using computerized tomography(CT). Thickness measurements were performed in 84 adult patients who took CT on maxilla for implant surgery and 24 standard measurement points were defined in the hard palate according to the gingival margin and mid palatal suture. Radiographic measurements were utilized after calibration for standardization. Data were analyzed to determine the differences in mucosal thickness by gender, age, tooth positions and depth of palatal vault. The results of this study were as follows: 1. Mean thickness of palatal masticatory mucosa was 3.93+/-0.6mm and females had significantly thinner mean masticatory mucosa(3.76+/-0.56mm) than males(4.04+/-0.6mm)(p<0.05). 2. The thickness of palatal masticatory mucosa increased by aging. 3. Depending on position, masticatory mucosa thickness increased from canine to premeolar, but decreased at the first molar, and increased again in the second molar region(p<0.0001). 4. No significant difference in mean thickness of palatal masticatory mucosa were indentified between low palatal vault group and high palatal vault group(p>0.05). The results suggest that canine and premolar area appears to be the most appropriate donor site for soft tissue grafting procedure. The measurement of the thickness of palatal masticatory mucosa by using computerized tomography can offer useful information clinically but further studies in assessing the validity and reliability of the method using computerized tomography is needed.
