He required catheter removal due to the peritonitis being suspected of relapsing. Although so further investigations are required, it is possible that early catheter removal is effective in cases in which another organism is newly detected during antibiotic therapy for PD-related peritonitis caused by a different responsible organism not meeting the definition of refractory peritonitis.In recent times, the diagnosis and treatment of superficial laryngopharyngeal cancers has been receiving a lot of attention. Here, we present a case of superficial hypopharyngeal cancer and superficial esophageal cancer for which endoscopic laryngo-pharyngeal surgery (ELPS) and endoscopic submucosal dissection (ESD) were performed simultaneously. The patient was a 67-year-old male. During his follow-up for distal gastrectomy performed earlier for stomach cancer, an upper gastrointestinal endoscopy revealed three primary cancers superficial hypopharyngeal cancer, superficial esophageal cancer, and esophagogastric junction cancer. Total resection of the remnant stomach was performed followed by hypopharyngeal ELPS combined with esophageal ESD. He developed aspiration pneumonia after the surgery; however, he recovered and was discharged on the 16th day. Thus, safe and effective endoscopic therapy can be performed even for double superficial cancers of the laryngopharynx and esophagus.Effective leukemia treatment is seriously hampered by drug resistance. The possible roles of epigenetic mechanisms have recently been considered in cancer drug resistance. With conventional anti-cancer drugs, including alkylating drugs, anti-metabolite drugs, topoisomerase inhibitors, and microtubule inhibitors, which have been available for half a century, the drug resistance often occurs due to decreased expression of target enzymes, with increased expression of drug export pumps. The alterations of target gene expression and increased export pump function might be caused by epigenetic changes, such as changes of methylation status, as well as changes of histone acetylation status. In addition, newly developed anti-cancer drugs, including small molecule drugs such as kinase inhibitors, antibody drugs, and immune modulatory drugs, also showed development of drug resistance within a year, although these drugs show significant efficacy in conventional anti-cancer drug-resistant patients. The resistant cells showed increased expression of bypass pathways, activation of downstream cascades, decreased expression of antigens of tumor cells, increased DNA repair activity, and increased expression of drug export pumps, also suggesting epigenetic changes. In this paper, drug resistance to cancer therapy and the possible roles of epigenetic mechanisms are reviewed.Purpose Off-pump coronary arterial bypass grafting (OPCAB) has become a common practice for coronary artery bypass grafting (CABG) in Japan, with approximately 65% CABG procedures currently being performed using OPCAB. However, it is unclear whether OPCAB is superior in terms of associated mortality, incidence of complications, graft patency rate, and long-term outcomes compared with conventional CABG (CCABG). Methods Literature consideration was performed, mainly based on observational studies involving large samples and randomized controlled trials (RCTs). Results Many RCTs indicated that the acute-phase and long-term mortality rates were comparable between CCABG and OPCAB or that OPCAB was inferior to CCABG. In contrast, many observational studies indicated that OPCAB was superior to CCABG. Conclusion CABG is a delicate procedure, the outcomes of which vary in accordance with the patient's condition as well as the level of expertise of the associated institution and surgeon. In the future, we hope that reports will emerge with excellent results, including long-term results, from Japanese institutions experienced in performing OPCAB.Purposes Patients who require surgeries for traumatic post-tracheotomy tracheal stenosis (PTTS) often cannot be supported using conventional airway management approaches. This study documents the use of extracorporeal membrane oxygenation (ECMO) in patients with PTTS. Methods Patient characteristics, procedure, and outcome of patients who required tracheal reconstruction surgery for PTTS supported by ECMO were retrieved and analyzed. GW4064 cell line Results Four patients (mean age 28 years; range 17-48 years) with traumatic PTTS underwent tracheal reconstruction surgery supported by ECMO. The mean time from removal of tracheotomy tube to admission was 3.2 months (range 1-9 months). The mean diameter of the stenotic segment was 5 mm (range 4-6 mm). One patient underwent tracheoplasty and semi-tracheostomy with venoarterial ECMO urgently. Three patients underwent tracheal resection and end-to-end anastomosis (TRE) with venovenous ECMO empirically. Intervention success was achieved in 100% (4/4) of patients. The mean duration of ECMO was 35.3 hours (range 16-53 hours). The overall survival rate was 100% (4/4) within a mean follow-up of 26 months (range 7-57 months). Conclusions ECMO is a safe and feasible method to support oxygenation for patients with critical traumatic PTTS during tracheal reconstruction surgery.We examined the effects of a single or 2.5-fold dose of dephereline [a gonadotropin-releasing hormone (GnRH) analogue] as well as the drainage of the smaller follicle at the time of insemination on ovulation in dairy cows with two follicles of pre-ovulatory size in the same ovary. The three study groups included 220 monovular cows (control), 110 non-drained cows with two follicles, and 110 cows with two follicles, of which one was drained. In each group, cows treated with a single dose or 2.5-fold dose of dephereline showed similar results following treatment. Ovulation failure of the non-drained follicle occurred in 29.1% of the drained cows, whereas ovulation occurred in 96% of the non-drained and control cows. Twin pregnancy was recorded in 19.4% of the pregnant non-drained cows with two follicles. In conclusion, the increased dephereline dose did not improve the ovulation rate in any group. Follicular drainage, however, prevented twin pregnancy in cows with two follicles, but also resulted in an increase in the non-drained follicle's rate of ovulation failure.
