Aim: To determine the effectiveness of ventilations in bystander cardiopulmonary resuscitation (BCPR) and to identify the factors associated with ventilation-only BCPR. Methods: From out-of-hospital cardiac arrest (OHCA) data prospectively collected from 2005 to 2011 in Japan, we extracted data for 210,134 bystander-witnessed OHCAs with complete datasets but no prehospital involvement of physician [no BCPR, 115,733; ventilation-only, 2093; compression-only, 61,075; and conventional (compressions+ventilations) BCPR, 31,233] and determined the factors associated with 1-month neurologically favourable survival using simple and multivariable logistic regression analyses. In 91,885 patients with known BCPR durations, we determined the factors associated with ventilation-only BCPR. Results: The rate of survival in the no BCPR, ventilation-only, compression-only and conventional group was 2.8%, 3.9%, 4.5% and 5.0%, respectively. After adjustment for other factors associated with outcomes, the survival rate in the ventilation-only group was higher than that in the no BCPR group (adjusted OR; 95% CI, 1.29; 1.01-1.63), but lower than that in the compression-only (0.76; 0.59-0.96) or conventional groups (0.70; 0.55-0.89). Conventional CPR had the highest OR for survival in almost all OHCA subgroups. The adjusted OR (95% CI) for survival after dividing BCPR into ventilation and compression components was 1.19 (1.11-1.27) and 1.60 (1.51-1.69), respectively. Older guidelines, female sex, younger patient age, bystander-initiated CPR without instruction, early BCPR and short BCPR duration were associated with ventilation-only BCPR. Conclusions: Ventilation is a significant component of BCPR, but alone is less effective than compression in improving neurologically favourable survival after OHCAs. © 2015 Elsevier Ireland Ltd.

Several thoracoscopic fissureless lobectomy techniques have been reported;however, the indications for the same remain controversial. One of the reasons for conversion to open lobectomy is the swelling or inflammation of lymph nodes between the lobar bronchus and the adjacent pulmonary artery. In this report, we advocate temporary segmental bronchus incision technique(T-BIT)and describe its application for lung cancer patients with fused fissures. T-BIT involves initial segmental bronchus incision before lobar bronchus stapling to safely dissect the lymph nodes between the lobar bronchus and the pulmonary artery. Eight patients who underwent thoracoscopic fissureless lobectomy with T-BIT between August 2014 and August 2016 were included in the study. Five patients underwent left upper lobectomy, one underwent left lower lobectomy, and 2 underwent right middle lobectomy. With T-BIT, complete peribronchial lymph node dissection was easily performed in all patients. There were no intraoperative complications, such as pulmonary artery bleeding or pulmonary injury. The postoperative chest tube drainage time was 2.5±0.5 days. Taken together, T-BIT appears useful for lymph node dissection in thoracoscopic fissureless lobectomy.

Purpose To evaluate the feasibility of diffusion-weighted magnetic resonance imaging (DW-MRI) for assessment of the early response to chemotherapy and outcome in patients with advanced lung cancer through comparison with fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) and computed tomography (CT). Materials and Methods Twenty-eight lung cancer patients underwent DW-MRI, FDG-PET, and CT before and after one course of chemotherapy. Changes in the apparent diffusion coefficient (ΔADC), the mean standardized uptake value (ΔSUV), and the maximum diameter (ΔMD) were measured and compared. According to the response evaluation criteria, patients were divided into two groups, responders and nonresponders, and progression-free survival (PFS) and overall survival (OS) were estimated. Results The relationship between ΔADC and ΔSUV had the highest correlation coefficient. A cutoff value of ΔADC between responders and nonresponders was estimated as 21.5%. PFS and OS between responders and nonresponders were significantly different on DW-MRI (PFS, P = 0.012; OS, P = 0.006) and on FDG-PET (PFS, P = 0.017; OS, P = 0.036), but not on CT (PFS, P = 0.105; OS, P = 0.051). Conclusion DW-MRI can be used to predict prognosis in patients with advanced lung cancer. © 2012 Wiley Periodicals, Inc.

Human herpesvirus-6 (HHV-6) is a major cause of limbic encephalitis with a dismal prognosis after allogeneic hematopoietic SCT (HSCT). A prospective, multicenter study was conducted to assess the safety and efficacy of preemptive therapy with foscarnet sodium (PFA) for the prevention of HHV-6 encephalitis. Plasma HHV-6 DNA was measured thrice weekly from day 7 until day 36 after umbilical cord blood transplantation (UCBT) or HSCT from HLA-haploidentical relatives. PFA, 90 mg/kg/day, was started when HHV-6 DNA exceeded 5 × 102 copies/mL. Mild and transient adverse events were associated with PFA in 7 of 8 patients. Twelve of 15 UCBT recipients became positive for HHV-6 DNAemia, defined by greater than 1 × 102 copies/mL of HHV-6 DNA in plasma. The virus exceeded 5 × 102 copies/mL in seven patients, whereas none of the five HLA-haploidentical HSCT recipients became positive. One patient developed mild limbic encephalitis just after initial PFA administration. Preemptive PFA therapy is safe, but as HHV-6 DNAemia can abruptly develop before neutrophil engraftment in UCBT recipients, prophylactic PFA administration from day 7 or earlier after UCBT may be needed. © 2011 Macmillan Publishers Limited All rights reserved.

Background - : Dispatcher-assisted cardiopulmonary resuscitation (DA-CPR) attempts to improve the management of out-of-hospital cardiac arrest by laypersons who are unable to recognize cardiac arrest and are unfamiliar with CPR. Therefore, we investigated the sensitivity and specificity of our new DA-CPR protocol for achieving implementation of bystander CPR in out-of-hospital cardiac arrest victims not already receiving bystander CPR. METHODS AND RESULTS - : Since 2007, we have applied a new DA-CPR protocol that uses supplementary key words. Fire departments prospectively collected baseline data on DA-CPR from January 2009 to December 2011. DA-CPR was attempted in 2747 patients; of these, 417 (15.2%) did not experience cardiac arrest. The sensitivity and specificity of the 2007 protocol versus estimated values of the previous standard protocol were 72.9% versus 50.3% and 99.6% versus 99.8%, respectively. We identified key words that may be useful for detecting out-of-hospital cardiac arrest. Multiple logistic regression analysis revealed that the occurrence of cardiac arrest after an emergency call (odds ratio, 16.85) and placing an emergency call away from the scene of the arrest (odds ratio, 11.04) were potentially associated with failure to provide DA-CPR. Furthermore, at-home cardiac arrest (odds ratio, 1.61) and family members as bystanders (odds ratio, 1.55) were associated with bystander noncompliance with DA-CPR. No complications were reported in the 417 patients who received DA-CPR but did not have cardiac arrest. CONCLUSIONS - : Our 2007 protocol is safe and highly specific and may be more sensitive than the standard protocol. Understanding the factors associated with failure of bystanders to provide DA-CPR and implementing public education are necessary to increase the benefit of DA-CPR. © 2014 American Heart Association, Inc.

Several recent studies described that high-risk human papillomavirus (HPV) infection could have a potential role in the development of malignancies other than cervical cancer, such as laryngeal carcinoma, penile carcinoma, and anal carcinoma. However, the etiological role of HPV infection in the pathogenesis of urinary tract has not been clarified. Many epidemiological studies demonstrated that HPV infections frequently occur in the external genitalia through sexual contact; however, it was reported that HPV infection could also occur in the urinary tract, including the urethra and urinary bladder. Some morphological changes of cells associated with HPV infection and mild atypical cells, suspected to be intraneoplasia, were seen in HPV-positive samples obtained from the urinary tract. Some clinical studies and meta-analysis have indicated that HPV infection is likely to have a certain etiological correlation with the development of bladder carcinoma, although its prevalence may vary according to HPV type, study population, region, histological type, detection methods, and other variables. According to the results of previous studies, the prevalence of HPV greatly widely varies in cases of bladder carcinoma. Further research by case-control or large-scales studies is thus required to reach a more definite conclusion.

Intraoperative bleeding is one of the main severe complications in complete video-assisted thoracoscopic surgery (c-VATS). We investigated whether one sealing device, the LigaSureVTM (LSV) vessel sealing system (Valleylab, Tyco Healthcare, Boulder, CO, USA) was experimentally and clinically safe and effective for c-VATS. The burst pressures (BP) of each pulmonary artery (PA) in resected lungs were measured and were compared between a thin PA group (<5 mm) and a thick PA group (≥5 mm). To investigate the influences of the sealing situations to the adequacy of sealing, BPs were measured after dry or wet conditioned PA (soaked with 0.9% saline) were sealed and cut by the LSV. Clinically, a total of 203 PA were divided with the LSV in c-VATS. The BP of the thin PA with small diameters (<5 mm) were higher than the thick PA (607 mmHg vs. 447 mmHg; P<0.05). The sealing effect was higher when the thick PA was sealed in a dry state than in a wet state (447 mmHg vs. 399 mmHg; P<0.05). However, average BP was physiologically high enough to inhibit a burst even for thick PA sealed in a wet state. There was single case of delayed bleeding sealed PA resulted from seal contact with a sucton device. These studies demonstrated the safety and efficacy of the LSV to sealed PA in c-VATS. © 2010 Published by European Association for Cardio-Thoracic Surgery.

We report here a case of pulmonary benign metastasizing leiomyoma (BML) from the uterus. A 48-year-old woman was admitted to our hospital because of multiple pulmonary nodules on the chest radiograph 7 years after total hysterectomy with removal of the left ovarium for uterine leiomyoma. A specimen of the lesion obtained by a thoracoscopic lung biopsy was consistent with leiomyoma. Histological re-evaluation of the uterine myoma showed similar histology as compared with the lung tumor. Immunohistological staining for both estrogen and progesterone receptors on the lung tissue was positive. Based on these results, we diagnosed the pulmonary lesions as BML. The patient received no treatment and has shown no evidence of exacerbation of disease during 6 years of follow up.

We report a 28-year-old woman with O157 enterohemorrhagic colitis-associated hemolytic uremic syndrome in whom seizures and transient hemiparesis developed on the 12th day after admission to hospital. Her subsequent recovery was characterized by improvements in renal function and platelet count. The patient recovered after treatment with steroid pulse and plasma exchange therapy, without any sequelae. As there have been few reports on the onset of encephalopathy in adults, we report this interesting case, with reference to the literature for possible effective treatment.

Reduced port laparoscopic surgery has been used increasingly. It is a concept that has grown out of the various efforts aimed at minimally invasive surgery, with SILS being the ultimate reduced port technique. Reduced port laparoscopic surgery has been used to perform sleeve gastrectomy in bariatric surgery and excision of benign gastric submucosal tumor, applications that generally do not require lymph node dissection or complicated reconstruction. It can be done safely, result in a permanent cure, and offer good cosmetic outcomes. Reduced port laparoscopic surgery for gastric cancer has a short history, and its usefulness has not yet been fully established. This review describes the present situation and challenges faced as well as standardized procedures and the future prospects of reduced port laparoscopic gastrectomy for gastric cancer, which my team performs almost daily. These aspects of reduced port laparoscopic surgery are presented in light of the literature. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.
