A 60-year-old man with type 2 diabetes mellitus and severe obesity (height 170 cm, weight 160 kg, BMI 55) was admitted to our hospital because of acute inferior wall myocardial infarction due to acute thromboembolism of the right coronary artery (RCA). Because of three-vessel coronary diseases, we planned coronary artery bypass grafting after the medical therapy. The patient was intubated, then suffered congestive heart failure and pneumonia, and had a tracheotomy because of obesity hypoventilation syndrome. When his general condition improved after 14 months of medical therapy, we performed the operation. At that time, his weight had decreased to 107.5 kg, and BMI decreased to 37.2. We decided that tracheotomy was necessary to avoid respiratory complications. We chose a thoracoabdominal spiral incision for 2 reasons. Firstly we needed to avoid wound contamination by the tracheotomy stoma. Secondly we decided that the left internal thoracic artery (LITA) and the right gastroepiploic artery (RGEA) were sufficient for bypass grafts to the left anterior descending artery (LAD), the diagonal branches (D1), the posterolateral artery (PL) and the posterior descending artery (PD). Before the operation, epidural anesthesia was performed for postoperative analgesia to prevent respiratory dysfunction. In the right semi-lateral position at 30°, a 4th intercostal space thoracotomy was performed, and the LITA was harvested. The skin incision was extended to the midline of the abdomen and the RGEA was harvested. The end of the LITA was anastomosed with the free RGEA as I composite and the composite was anastomosed to the LAD, the D1, the 14 PL and the 4 PL without cardiopulmonary bypass. Without any perioperative blood transfusion, the patient was discharged with no perioperative complication, including mediastinitis. With this incision, we achieved secure prevention of wound contamination by the tracheotomy stoma, harvesting of a sufficient length of the LITA and RGEA and good visualization of the anastomotic sites with less cardiac displacement than median sternotomy.

Cardiovascular surgeons have strong preferences regarding basic surgical skills. However, those basic skills have never been discussed great detail. The aim of this study is to survey the approach methods for axillary and subclavian artery targeting cardiovascular surgeons in Japan aged under 40, and to share the results of those basic skills.

STUDY DESIGN: Retrospective cohort study. PURPOSE: To investigate the effect of spinal correction on respiratory muscle strength in patients with Duchenne muscular dystrophy (DMD). OVERVIEW OF LITERATURE: Several studies have reported that scoliosis correction in patients with DMD does not improve pulmonary function. In these studies, pulmonary function was evaluated using the traditional spirometric values of percent vital capacity (%VC) and percent forced vital capacity (%FVC). However, traditional spirometry may not be suitable for patients with DMD because the results can be influenced by patient fatigue or level of understanding. Therefore, we evaluated respiratory function focusing on respiratory muscle strength using maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and sniff nasal inspiratory pressure (SNIP), in addition to %VC and %FVC. METHODS: We retrospectively reviewed 16 patients with DMD who underwent spinal correction surgery between 2006 and 2011 at Kitasato University Hospital. All patients were males, and the mean age was 13.5 years. Respiratory muscle strength was evaluated using MIP, MEP, and SNIP. Measurements were obtained preoperatively and at 1 and 6 months postoperatively, and %VC and %FVC were obtained preoperatively and within 6 months postoperatively. RESULTS: The mean preoperative and postoperative %VC values were 54.0% and 51.7%, whereas the mean %FVC values were 53.9% and 53.2%, respectively. The mean MIP, MEP, and SNIP values obtained preoperatively and at 1 and 6 months postoperatively were as follows: MIP, 40.5, 42.7 and 47.2 cm H₂O; MEP, 26.0, 28.0, and 29.0 cm H₂O; and SNIP, 33.4, 33.0, and 33.0 cm H₂O; respectively. The mean MIP and MEP values significantly improved postoperatively. There were no significant differences in SNIP, %VC, or %FVC preand postoperatively. CONCLUSIONS: By focusing on respiratory muscle strength, our results suggest that scoliosis correction in patients with DMD might have a favorable effect on respiratory function.

Background: Gingyo-gedoku-san (GGGS) is an herbal medicine approved for upper respiratory infections in Japan. We conducted an open-label, multi-center, prospective trial, comparing GGGS with oseltamivir in patients with influenza and influenza-like illness (ILI) as a pilot study.
Methods: Subjects were healthy persons aged between 16 and 40, and were enrolled from January 12, 2010 to March 24, 2011. Fifteen patients were enrolled in this trial (8 and 7 for GGGS and oseltamivir, respectively). RT-PCR was positive for pandemic influenza A (H1N1) in 10 patients. The patients were provided with either GGGS or oseltamivir for 5 days. The primary outcome was mortality and/or hospitalization 7 days after the initial diagnosis. Body temperature and other clinical characteristics were also evaluated.
Results: All patients recovered from illness without complication or hospitalization. The mean time to resolve symptoms for the GGGS and oseltamivir groups was 3.9 days and 3.3 days, respectively (p=0.43). The GGGS group appeared to have a smaller symptom score AUC than the oseltamivir group, (p=0.26). Time to recover activity level appeared to be shorter in the GGGS group (p=0.10), with shorter time to recover health status (p=0.02). Sub-group analysis on patients with positive PCR showed similar results between the two groups.
Conclusion: GGGS was associated with symptom improvements resembling oseltamivir for both influenza and ILI. Randomized controlled trials involving larger sample sizes are needed to confirm these results.
