Clinical cases of normothermic extracorporeal circulation (ECC) are increasing, but the possibility of brain damage is not clear.In emergencies, the brain protective effects of mild (33-34°C) hypothermic therapy have been clearly confirmed. Natural Temperature decrease ECC was conducted in this study, hoping to obtain the advantages of both normothermic ECC and brain protection by mild hypothermia. These were 12 cases at high risk of brain damage (10 cases of brain infarction and 2 cases of severe carotid artery stenosis). In all cases, coronary artery bypass grafting operation with natural temperature decrease ECC was performed. The average laryngeal temperature dropped to 33.0±0.3°C. There was no brain infarction or ICU syndrome. Evaluation of post-operative brain condition by the patients themselves and their families was good. The possibility of natural temperature decrease ECC for high risk cases of brain damage was demonstrated.

Objective: To determine the factors affecting the antimicrobial effect of VCM on MRSA.
Study Design: Case series study.
Methods: This study was conducted on pneumonia patients admitted to a university-affiliated hospital between January 2000 and December 2008 and had MRSA in their sputum culture. From seven days prior to the starting VCM administration through the end of the administration, detailed information such as underlying diseases, VCM serum concentration and quantity of MRSA were recorded. Logistic regression analysis was carried out on current diseases, trough concentration, surgery experience, and the detection of Gram-negative bacteria to verify the antimicrobial effect of VCM.
Results: The number of subjects investigated this study was 55 subjects. Multiple logistic regression analysis did not yield any significant factors when carried out using the factors affecting the antimicrobial effect of VCM on MRSA as independent variables.
Conclusions: Multivariable analysis yielded no factors as being significant in affecting the antimicrobial effect of VCM, but did indicate in that patients aged 70 and older, the antimicrobial effect of VCM was poor for MRSA. This suggests that when pharmacists intervene in antimicrobial treatment for improved effects, it is important to consider not only the serum concentration of VCM, but also the background of the patient.

Methods:
Sagittal spinopelvic alignment was evaluated in 110 subjects using radiographs of the whole spine. Parameters measured in this study included sagittal vertical axis (SVA), LL, sacral slope (SS), pelvic tilt (PT), and pelvic incidence (PI). The distribution of sagittal plane modifier grade was evaluated according to the Scoliosis Research Society-Schwab classification of adult spinal deformity (ASD). Consequently, personal history related to LBP was obtained, and the association of pre- and postoperative LBP and spinopelvic alignment was investigated.
Results:
Preoperatively, 66% of all subjects showed LBP and mostly exhibited anteriorly shifted global imbalance associated with a decrease in LL and knee flexion contractures, and the subject who had severe flexion contracture of the knee joint showed more forwardly shifted global balance with backward PT and decrease in LL. After TKAs, the knee flexion contractures were eliminated in most cases, and one-third of subjects experienced decrease in LBP. However, SVA increased more and associated with slight decrease of PT and increase of SS. No significant differences were confirmed between pre- and postoperative values of LL and PI. In addition, there were no significant differences in postoperative values of spinopelvic parameters between subjects with and without relieved LBP.
Conclusions
Although one-third of subjects experienced decrease of LBP after TKAs, the sagittal global imbalance was not restored through the removal of knee flexion contracture.

Objective To assess the effect of D-JNKI1, an inhibitor of c-Jun N-terminal kinase (JNK), on delayed neuronal death (DND) in a gerbil model of transient global cerebral ischemia, so as to further study the roles of JNK activation in mediating neuronal cell death in brain ischemia. Methods Fifty-five Mongolian gerbils were randomly divided into 11 groups. Animals (n=35) assigned into 7 groups (n=5 per group) were subjected to 5-min occlusion of bilateral common carotid arteries (BCCAO);among the 7 groups, different doses of D-JNKI1 (0.00012, 0.0012, 0.012, 0.12, 1.2 μmol/L in 2 μL PBS,n=5 each) were administered stereotaxically into right lateral ventricles 3 h after reperfusion; the control group (n=5) received 2 μL PBS; and another group (n=5) received 1.2 μmol/L of D-JNKI1 in 0.5 mL PBS intraperitoneally. Sham-operated animals (n=5) only received the exposure of bilateral common carotid arteries without occlusion. Three groups (n=5 in each) were pretreated with D-JNKI1 (0.00012,0.0012 μmol/L in 2 μL PBS) or only 2 μL PBS 30 min before 2-min BCCAO, and subjected to 5-min BCCAO 48 h after the first ischemic insult. All animals were sacrificed 4 d after 5-min BCCAO and prepared for frozen section and Nissl staining. Results The treatment with D-JNKI 3 h after 5-min ischemia was neuroprotective with a maximum effect at a dose of 0.0012 μmol/L. Pretreatment with D-JNKI augmented ischemic tolerance induced by 2-min ischemia. Conclusion D-JNKI1 has a potential neuroprotective effect on DND in CA1 of hippocampus in gerbils with global cerebral ischemia-reperfusion injury.

BACKGROUNDIn an earlier study, we identified a locus for Moyamoya disease (MMD) on 17q25.3.
METHODSLinkage analysis and fine mapping were conducted for two new families in additional to the previously studied 15 families. Three genes, CARD14, Raptor, and AATK, were selected based on key words, namely, "inflammation", "apoptosis", "proliferation", and "vascular system", for further sequencing. A segregation analysis of 34 pedigrees was performed, followed by a case-control study in Japanese (90 cases vs. 384 controls), Korean (41 cases vs. 223 controls), Chinese (23 cases and 100 controls), and Caucasian (25 cases and 164 controls) populations.
RESULTSLinkage analysis increased the LOD score from 8.07 to 9.67 on 17q25.3. Fine mapping narrowed the linkage signal to a 2.1-Mb region. Sequencing revealed that only one newly identified polymorphism, ss161110142, which was located at position -1480 from the transcription site of the Raptor gene, was common to all four unrelated sequenced familial affected individuals. ss161110142 was then shown to segregate in the 34 pedigrees studied, resulting in a two-point LOD score of 14.2 (P = 3.89 × 10(-8)). Its penetrance was estimated to be 74.0%. Among the Asian populations tested (Japanese, Korean, and Chinese), the rare allele was much more frequent in cases (26, 33, and 4%, respectively) than in controls (1, 1, and 0%, respectively) and was associated with an increased odds ratio of 52.2 (95% confidence interval 27.2-100.2) (P = 2.5 × 10(-49)). This allele was, however, not detected in the Caucasian samples. Its population attributable risk was estimated to be 49% in the Japanese population, 66% in the Korean population, and 9% in the Chinese population.
CONCLUSIONss161110142 may confer susceptibility to MMD among East Asian populations.

The patient was a 68-year-old woman who was diagnosed with stage IIIA cervical cancer and pyometra. Concurrent chemoradiotherapy was planned. She was admitted to our hospital 3 weeks after the initial examination due to vaginal bleeding and worsening of lower abdominal pain. On hospital day 5, she developed a fever, and free gas in the peritoneal cavity and ascites were confirmed by contrast-enhanced computed tomography. Emergency surgery was performed for suspected generalized peritonitis attributed to perforation in the digestive tract or uterus. A large amount of purulent ascites and 2 perforations in the anterior wall of the uterus, but none in the digestive tract, were observed. Peritoneal lavage and drainage were performed, and a colostomy was created. The patient was managed in the intensive care unit until postoperative day 13 due to septic shock and acute renal failure. After the peritonitis resolved, radiation therapy alone was provided, and then chemotherapy was started to treat residual lesions. Pyometra recurred, and transvaginal drainage was performed to prevent perforation of the uterus. However, a few days later, a colouterine fistula and an enterocutaneous fistula developed simultaneously, and her general condition worsened. In advanced cervical cancer complicated by pyometra, various complications can develop that are difficult to manage (e.g., uterine perforation and fistula formation due to radiation enteritis and dermatitis). This case demonstrates the importance of uterine drainage at appropriate timing, which can contribute to improved prognosis.
