This study was performed to clarify the analgesic effect of ketamine injected into the first intercoccygeal (Co1-Co2) epidural space in standing cattle. Five adult cows were randomly received 3 treatments at least 1 week interval: 5, 10 and 20 mL of 5% ketamine. Sedation, analgesia, ataxia and other effects on cardiopulmonary and rumen functions were assessed before ketamine administration and until 120 min. The analgesia without sedation was shown at tail and perineum about 5 min after all three treatments. The duration of analgesia was significantly increased according to the volume of ketamine (p < 0.01). There was a similar tendency of ataxia with individual variation. There were minimal effects on cardiopulmonary and rumen functions. The present study showed that caudal epidural ketamine administration induced analgesia without sedation in cows, and the duration of analgesia was dose dependent with ataxia. However, the duration of analgesia after 5 and 10 mL ketamine administration is short for common surgical procedures and pain relief of perineum. Further studies are needed to prolong the duration of analgesia without side effects.

Before we moved into the present hospital building in October 2000, we took the opportunity to thoroughly review our medical equipment management system and developed a new centralized management system. With the introduction of the new system, we have made a complete list [an inventory] of medical equipment on hand from small-size instruments to large-scale machinery. We have now become able to grasp the frequency of use of ME, the cause of mechanical trouble, the cost of repairing and so forth. In the future, this system will be further improved so as to enable us to incorporate a labor-saving procedure for equipment lending into the system, share information with other departments, and work out a net working rate and repair rate to make purchasing or disposal plans.Medical care and health services of today cannot be provided without use of modern medical equipment. Under the circumstances, the prevention of accidents and grasp of the optimum amount of machinery and equipment are important. At the same time, the reduction of cost by adequate maintenance work is essential. We think that our centralized equipment management system will work effectively and serve the purpose.

A 64-year old man was admitted to our hospital with a diagnosis of aortic stenosis. Pre-operative chest CT revealed pseudocoarctation of the aorta with a hypoplastic aortic arch, elongation and kinking of the aortic arch and proximal descending aorta. There was also a large aneurysm from the distal arch to descending aorta. We performed a single-stage repair of the aortic lesion from the ascending to the descending aorta with aortic valve replacement. For the surgical approach, transverse clamshell incision was applied safely. Concomitant aortic valve replacement in surgical repair of pseudocoarctation and thoracic aneurysm was rare, and clamshell incision seemed beneficial in such single-stage repair from the aortic root to the descending aorta.

Objective:
This study aimed to investigate the effect of incorporating tumor laterality into the International Federation of Gynecology and Obstetrics (FIGO) staging system for advanced ovarian cancer.
Methods:
The clinical data of 131 patients with advanced ovarian cancer treated between 2008 and 2018 were retrospectively reviewed. To investigate the prognostic significance of tumor laterality, we divided the patients into unilateral and bilateral groups. The prognostic significance of tumor laterality (bilateral vs. unilateral) was evaluated using univariate and multivariate analyses. The effect of incorporating tumor laterality into the FIGO staging system to predict survival outcomes was evaluated using the Kaplan-Meier method.
Results:
Both overall survival (OS) and progression-free survival (PFS) were longer in the unilateral group than in the bilateral group. Multivariate analysis demonstrated that tumor laterality was an independent predictor of OS (hazard ratio, 1.75; confidence interval, 1.05-2.92; P=0.032). In patients with stage III disease, the bilateral group had a shorter OS than the unilateral group, but it was comparable to the OS in stage IV patients (P=0.354). The incorporation of tumor laterality into the FIGO staging system improved the stratification of survival probabilities.
Conclusion
Tumor laterality can be an independent prognostic factor in patients with advanced ovarian cancer. The incorporation of tumor laterality may improve the predictive performance of the FIGO staging system in patients with advanced ovarian cancer.

Objectives: We developed versions 2 and 3 of the Biological Prognostic Score (BPS) for advanced cancer patients and confirmed the prediction accuracy. Methods: We conducted a parametric survival analysis using blood test data, performance status (PS), clinical symptoms, age, sex, and cancer type as variables for advanced cancer patients who completed or suspended cancer treatment, in the development of BPS2 and BPS3. We then prospectively compared the accuracy between BPS2/BPS3 and the Palliative Prognostic Index (PPI). Results: We developed the BPS2 and BPS3 based on the data from 589 patients in a development cohort. While the former version was calculated based on the cholinesterase, blood urea nitrogen, and white blood cell counts, the latter was calculated based on the BPS2, ECOG PS and edema. For 206 patients in a validation cohort, the overall accuracy in prediction of survival for 3 and 6 weeks using the BPS2 and BPS3 were significantly higher than those for the PPI. Conclusion: The usefulness of BPS2 and BPS3 was suggested.

BACKGROUND/AIMS: Our physicians work to expand the possibilities to treat female patients with inflammatory bowel disease (IBD) who wish to become pregnant. Although many drugs, including 5-aminosalicylate (5-ASA), corticosteroids, immunomodulators, and biologics, are used safely during pregnancy, few reports have described the therapeutic regimen throughout pregnancy and the management of patients who relapse during pregnancy precisely. The aim of this study was to assess the management of patients with IBD during pregnancy. METHODS: We identified 19 patients (five with Crohn's disease and 14 with ulcerative colitis [UC]) who became pregnant with a total of 23 pregnancies between May 2005 and May 2015 by reviewing the medical records of Kyoto University Hospital. The following data were collected: the maternal variables, the IBD treatment type, the disease activity, the pregnancy outcome, and the mode of delivery. RESULTS: Among the 19 patients, 18 had become pregnant after being diagnosed with IBD, while one had developed UC newly after pregnancy. Throughout the gestation, all patients were treated with probiotics, 5-ASA, prednisolone, cytapheresis, or infliximab. The relapse rate during pregnancy was 21.7% (5/23 cases). The five patients who experienced a relapse were able to pursue their pregnancy after intensification of their treatments. There were no adverse fetal or neonatal problems, except in one case that required an emergency Caesarean section because of placental dysfunction and in which a very low-birth-weight infant was born preterm. CONCLUSIONS: Our present data confirmed that even if the disease flares up during pregnancy, good pregnancy outcomes can be achieved with an optimal intensification of the patient's treatment.

Human cytomegalovirus (HCMV) is a member of the herpesvirus family. HCMV infection persists throughout the host lifespan in a latent state following primary infection. The ability of HCMV to escape control by the host immune system and its resulting reactivation suggests the importance of ongoing immune surveillance in the prevention of HCMV reactivation. HCMV is a common cause of opportunistic infection that causes severe and fatal disease in immune-compromised individuals. In inflammatory bowel disease patients, particularly those with ulcerative colitis (UC), HCMV is often reactivated because these patients are frequently treated with immunosuppressive agents. This reactivation exacerbates colitis. Additionally, HCMV infection can induce severe colitis, even in patients with UC who have never been treated with immunosuppressive agents. However, the role of HCMV in colonic inflammation in patients with UC remains unclear. Here, we present previous and current clinical data on the diagnosis and treatment of HCMV infection in UC. Additionally, our experimental data from a newly established mouse model mimicking UC with concomitant CMV infection clearly demonstrate that inflammation could result in the exacerbation of UC disease activity with induction of HCMV reactivation. In summary, optimal control of colonic inflammation should be achieved in UC patients who are refractory to conventional immunosuppressive therapies and are positive for HCMV.

Natural habitat fragmentation and reducing habitat quality have resulted in an increased appearance of Japanese macaques, Macaca fuscata (Gray, 1870), in suburban areas in Japan. To investigate the risk of zoonotic infections, a coprological survey of helminth eggs passed by wild Japanese macaques was carried out in 2009 and 2010 in Shiga Prefecture, Japan. Microscopic examination found helminth eggs in high prevalence, and nucleotide sequencing of DNA extracted from the eggs identified Oesophagostomum cf. aculeatum and Trichuris trichiura. A fecal culture also detected infective larvae of Strongyloides fuelleborni. These zoonotic nematodes pose a potential health issue to local people in areas frequented by Japanese macaques.
