    1.OBJECTIVES To investigate the physiological states of goat fetuses undergoing extrauterine incubation following isolation from their mother, we analyzed fetal electroencephalograms (EEGs) with power spectral analysis. 2.MATERIALS AND METHODS Ten goat fetuses at 124± 3.9 days of gestation (term 150 days) were incubated in an artificial womb connected to an extracorporeal membrane oxygenation (ECMO) apparatus. While these fetuses were in a stabilized condition, their EEGs were recorded using a digital data recorder. Electrocortical activity on the EEGs was classified visually as either a high-voltage period or a low-voltage period. The recorded data were then analyzed using a computer. After analogue-to-digital conversion at a sampling frequency of 300Hz with a resolution of 16 bits, power spectral analysis using an auto-regression model was carried out. 3.RESULTS Both high-voltage and low-voltage periods could be observed on the EEGs of all ten goat fetuses, and these periods appeared to alternate. Power spectral analysis of recorded EEGs in the high-voltage period showed a peak at the 0.5-4 Hz frequency range, which corresponds to the delta band. A peak at the 8-13 Hz frequency range, which corresponds to the alpha band, was observed in the low-voltage period. 4.CONCLUSION During extrauterine incubation, goat fetuses showed two different EEG patterns. This suggests that the fetuses show physiological behavioral states that are independent from those of their mother.

    Objective : Acquisition of professional competence is a difficult, but very important task for physicians. In order to clarify methods of building professional competence, a questionnaire survey focusing on growth-satisfaction-rating was conducted among recent graduates. Methods : Major components necessary for acquisition of professional competence were defined as relationship, context, cognitive, habits of mind, affective/moral, and integrative. Questions regarding the acquisition of these components were created and sent to 1186 physicians who had graduated from Juntendo University School of Medicine between 1992 and 2006. The responses to the survey were analyzed in relation to the number of years after graduation, gender, specialty, university staff or private practice, and as a whole. The data were analyzed using multiple regression analysis, and growthsatisfaction-rating was used as dependent variable. Results : The response rate was 40.6%. The responses showed that cognitive, habits of mind, affective/moral, and integrative skills were more easily built. However, relationship and context seemed to be difficult to build. Conclusion : This study suggested that when we consider building professional competence, the daily study environment and situation should be designed to further emphasize the building of relationships and context as well as the other components.

    A 62-year-old woman complained of right lower abdominal pain without any systemic or local signs. Laboratory tests demonstrated elevated serum CEA levels. Pelvic CT showed a small mass in the right pelvic cavity. PET/CT showed enhancement with FDG accumulation in the lesion. The initial preoperative suspicion was malignant epithelial tumor involving the vermiform appendix, but ovarian tumor was not excluded. Exploratory single incisional laparoscopic surgery (SILS) was performed. SILS confirmed that the mass originated from the appendix and infiltrated to the right adnexa uteri and distal mesoileum. Considering that this was most likely advanced cancer, the procedure was converted to open surgery. Frozen section pathological examination of the en bloc resected specimen demonstrated a primary appendiceal adenocarcinoma. Ileocolectomy was subsequently performed. In this case, we used PET/CT and SILS as diagnostic tools and found both of these to be helpful.

    Beginning in November 2009, we implemented independent standardized guidelines for deep vein thrombosis (DVT) and pulmonary embolism (PE) in surgical patients. The flow of screening and prophylaxis are as follows;check for risk factors of DVT and PE on the template of electronic clinical record, automatically total the scores for risk factors, classify patients into four groups, perform the applicable prophylaxis in each group. As a result of applying these guidelines to 433 cases over 6 months, we detected 9 cases of thrombosis and performed appropriate treatments. There is increasing interest in DVT and PE throughout our hospital and this attempt to address this problem seems to have been successful.
