抄録 We treated a 72-year-old Japanese female with sustained high fever and overall body exhaustion. An infectious liver cyst and right lung pneumonia were suspected causes. Hepatic cystectomy and various antibiotics did not resolve symptoms. Pneumonia exacerbation and ascitic fluid retention, left lumbar spinal osteomyelitis, and peri-gastric lymph node abscess penetrating the stomach were observed. Mycobacterium avium was identified in sputum, ascites, vertebral body abscess puncture specimen, and pus mucus secretion in the stomach. We diagnosed a disseminated nontuberculous mycobacterial infection. She seemed immunocompetent, without signs of AIDS or hematological malignancy. Serum anti-IFN-γ autoantibodies tested positive and were suspected to be involved in the illness onset.

抄録 The electrical activity of the diaphragm (EAdi) shows global diaphragmatic activation and power output from the central nervous system. We measured the EAdi as an indicator of breathing workload in a 40-year-old man suffering from severe acute respiratory distress syndrome (ARDS) secondary to influenza pneumonia in the process of weaning from extracorporeal membrane oxygenation (ECMO). Turning off the sweep gas flow immediately led to EAdi elevation, followed by hypoxia. The patient was successfully weaned from ECMO by reference to EAdi. This is the first case report to suggest that EAdi monitoring might be useful for ARDS patients during ECMO weaning.

抄録 Internal limiting membrane (ILM) peeling is an important maneuver in vitrectomy for macular holes (MHs). A nitinol loop is a surgical instrument designed to create an edge on the ILM and peel the ILM safely and consistently. The effect of using a nitinol loop for ILM peeling on the retina is not clear. We report here on a case of an idiopathic full-thickness MH in an adult woman, in whom retinal damage was revealed after her ILM was peeled using a nitinol loop.

抄録 Although spinal cord stimulation (SCS) is a useful treatment for chronic intractable pain, the optimal method of stimulation has not yet been established. In this prospective, crossover study, we compared the efficacy of using a constant current (CC) system with that of a constant voltage (CV) system for temporal SCS. Twenty patients were enrolled and divided into two groups. For 10 patients, a CV system was applied on Days 1-5, followed by the use of a CC system on Days 6-10. For the other 10 patients, a CC system was applied for the first five days, followed by a CV system for the subsequent five days. We evaluated the alteration of pain intensity using a visual analogue scale (VAS), the area of stimulation, the stability of effect, and patient satisfaction regarding treatment. The pain scores decreased significantly after the start of the SCS. There was no significant difference in the change in VAS between the two systems. The stimulation method used for temporal SCS did not affect the reduction of pain intensity. Patients felt a wider stimulation area by the CC system compared to the CV system.

抄録 We investigated the anatomical features of the axillary nerve and its accompanying vessels with respect to the lateral wall of the greater tuberosity, focusing on the relationship between the neurovascular bundle and the proximal humeral locking plates. Magnetic resonance images of 30 Japanese patients’ shoulders were examined. Oblique sagittal images across the greater tuberosity and the neurovascular bundle, which contain the axillary nerve and posterior circumflex humeral artery and vein, were obtained. The distance between the superior aspect of the greater tuberosity and the superior and inferior borders of the neurovascular bundles was measured at the anterior, middle, and posterior edges of the greater tuberosity. The neurovascular bundle was 28.5-36.7 mm, 32.6-41.3 mm, and 38.1-47.5 mm distal to the superior aspect of the greater tuberosity at the anterior, middle, and posterior edges, respectively. We evaluated the relationship between the neurovascular bundle and 3 different locking plates, which were placed at the lateral aspect of the greater tuberosity. Only 3 or four locking screws at the most proximal part could be safely inserted without axillary nerve interference.

抄録 Oral cancer is a very common disease in South and Southeast Asia. Betel quid (BQ)- chewing and tobaccosmoking habits are etiological factors for oral cancer patients in these regions. We conducted an oral cancer screening in BQ-chewing endemic rural areas in South Myanmar for the early detection of oral cancer in BQ-chewing and smoking individuals. We examined 105 subjects who were at high risk of oral cancer due to their oral habits (BQ users and/or smokers). Three carcinoma cases were detected, and there were 8 dysplasia cases. The carcinoma detection rate was 2.9%, and the carcinoma and precancerous lesion detection rate was 10.5%. In Myanmar, oral cancer screening has been conducted sporadically on a voluntary basis, and nationwide surveys have never been performed. There are also few reports of oral cancer screening for high-risk groups among the general population in Myanmar. Our present findings highlight the need for further screening and surveys. Education on betel quid chewing- and tobacco- related oral diseases and screening for the early detection of oral cancer are of the utmost importance in the control and prevention of oral cancer.

抄録 We evaluated the feasibility of maintenance treatment using UFT (a combination of tegafur and uracil) after adjuvant platinum-based chemotherapy in patients with resected lung cancer. A prospective feasibility trial was conducted. Between 2010 and 2014, UFT was administered for 2 years sequentially after platinum-based adjuvant chemotherapy in 24 patients with resected Stage IIA-IIIA non-small cell lung cancer. The safety of UFT and the rate of treatment completion were then evaluated. The prior platinum-based chemotherapy regimens consisted of cisplatin+vinorelbine in 16 patients, carboplatin+paclitaxel in 5 and carboplatin+S-1 in one. During the subsequent UFT administration, a total of 3 patients required a dose reduction because of Grade 1 blood-stained sputum, Grade 2 numbness, and Grade 2 constipation, in one patient each. Eleven patients underwent the planned 2-year UFT administration, but 12 patients could not because of the recurrence of lung cancer in 5 patients, metachronous malignancy in one, and toxicities in 6. The completion rate for UFT administration was 64.7% (11/17). The most common type of toxicity was gastrointestinal toxicities. All of the toxicities were grade 1 or 2, and no severe toxicities were observed. UFT treatment after platinum-based chemotherapy was revealed to be feasible.

抄録 (−)-Epigallocatechin-3-gallate (EGCG) has been shown to bind to several receptors including epidermal growth factor receptor (EGFR). EGFR tyrosine kinase inhibitors and anaplastic lymphoma kinase (ALK) inhibitors are effective for non-small cell lung cancers harboring activating EGFR mutations and ALK or c-ros oncogene 1 (ROS1) fusion genes, respectively. We investigated the effects of EGCG on EGFR- or fusion gene-driven lung cancer cells such as PC-9, RPC-9, H1975, H2228 and HCC78. The five cell lines had similar sensitivity to EGCG. Phosphorylated (p)EGFR, pAkt and pErk in PC-9, RPC-9 and H1975 cells were suppressed by EGCG (50 or 100 μM). EGCG also inhibited pALK in H2228, pROS1 in HCC78, and pErk and pAkt in both cell lines. All the xenograft tumors established using the 5 cell lines in EGCG-treated groups were significantly smaller than the tumors in the vehicle-treated groups. The numbers of tumor blood vessels of xenograft tissues in EGCG-treated mice were significantly lower than those in vehicle-treated mice. In conclusion, EGCG may be effective for EGFR-driven lung tumors irrespective of the presence of T790M, and for ALK or ROS1 fusion gene-driven lung tumors.

抄録 Lavender essential oil (Lvn) has anti-inflammatory effects in an ovalbumin-sensitized murine model of asthma, and inhibits inflammatory cell infiltration into the lungs. The anti-inflammatory effects of Lvn on cell adhesion molecules are not clear. Here we evaluated the effects of Lvn and its main constituents, linalyl acetate (LA) and linalool (LO), on the expression of tumor necrosis factor-alpha (TNF-α)-induced cell adhesion molecules in murine brain endothelial bEnd.3 cells and human umbilical vein endothelial cells (HUVECs). The bEnd.3 cells were treated with Lvn, LA, or LO and subsequently stimulated with TNF-α. The mRNA expression levels of cell adhesion molecules were detected using RT-PCR. E-selectin and P-selectin protein and phosphorylated-NF-κB p65 were detected by western blotting. The effects of Lvn on HUVECs were measured by RT-PCR. In bEnd.3 cells, Lvn and LA suppressed TNF-α-induced E-selectin, P-selectin, vascular cell adhesion molecule-1, intercellular adhesion molecule-1, and phosphorylated-NF-κB p65 in the nucleus; LO did not suppress P-selectin or phosphorylated-NF-κB p65. Lvn inhibited TNF-α-induced E-selectin mRNA in HUVECs. These results indicate that Lvn and LA inhibit TNF-α-induced cell adhesion molecules in endothelial cells through the suppression of NF-κB activation. Consequently, Lvn or other essential oils including LA may be useful as alternative anti-inflammatory medicines.

抄録 We examined postprandial body positions’ effects on gastrointestinal motility, the autonomic nervous system and subjective comfort, i.e., whether lowering the head after a meal is beneficial for gastrointestinal motility and the prevention of pressure ulcer. We examined 10 healthy subjects and compared 3 body positions: (1) Seated upright. (2) Lying on a bed with the head at 60° and knees up by 20° (60° position). (3) Identical to (2) until post-meal; the head was then lowered to 30° (60°-30° position). Gastrointestinal motility was assessed as gastrointestinal sounds measured by sound-editing software. Digital plethysmography assessed autonomic nerve function as heart rate variability. The pressure ulcer risk was estimated as subjective comfort/discomfort using a visual analog scale. Gastrointestinal sounds increased post-meal. The 60°-30° position showed the highest number of sounds and longest cumulative sound duration. Post-meal, sympathetic activation was suggested in the 60° position, whereas vagal activity was relatively preserved in the 60°-30° position. The 60°-30° position was the most comfortable, and the 60° position was least comfortable. Lowering the head after a meal is beneficial to augment gastrointestinal motility and decrease the pressure ulcer risk. The 60° head-up position increases the pressure ulcer risk.

抄録 Several reports discussed colonoscopic surveillance after polypectomy and endoscopic mucosal resection (EMR) for colorectal polyps, but only a few reports focused on prognostic analyses, and none involved metachronous neoplasia after colorectal endoscopic submucosal dissection (ESD). We conducted the present study to assess the risk of adenoma recurrence requiring endoscopic treatment, and to establish appropriate post-ESD colonoscopic surveillance. We enrolled 116 patients who had undergone colorectal ESD at Okayama University Hospital between February 2008 and July 2014 and had been followed-up >12 months. We retrospectively analyzed clinicopathological features of 101 lesions from 101 patients. Metachronous adenomas were detected in 21 cases (20.8%). We divided the patients into 2 groups according to the occurrence of metachronous adenomas. Our comparison of clinicopathological characteristics between these groups showed that in the metachronous adenomas group the number of synchronous adenomas at index colonoscopy was high and the rate of laterally spreading tumor-nongranular (LST-NG) was higher. A multivariate analysis indicated that the number of synchronous adenomas was significantly associated with metachronous adenomas (HR: 2.54, 95%CI: 1.04-6.52, p<0.05). The colonoscopic surveillance planning after colorectal ESD should be more meticulous for patients with more synchronous adenomas.

抄録 Early mobilization is advocated to prevent intensive care unit-acquired physical weakness, but the patient's workload and its changes in response to body position changes have not been established. We used indirect calorimetry to determine the energy expenditure (EE) in response to body position changes, and we assessed EE's correlation with respiratory parameters in healthy volunteers: 8 males and 8 females, mean age 23.4±1.3 years. The subjects started in the resting supine position followed by a 30° head-up position, a 60° head-up position, an upright sitting position, a standing position, and the resting supine position. EE was determined in real time by indirect calorimetry monitoring the subject’s respiratory rate, tidal volume (VT), and minute volume (MV). The highest values were observed immediately after the subjects transitioned from standing to supine, and this was significantly higher compared to the original supine position (1,450±285 vs. 2,004±519 kcal/day, p<0.01). Moderate correlations were observed between VT and EE (r=0.609, p<0.001) and between MV and EE (r=0.576, p<0.001). Increasing VT or MV indicates an increasing patient workload during mobilization. Monitoring these parameters may contribute to safe rehabilitation. Further studies should assess EE in critically ill patients.

抄録 The receptor for advanced glycation end products (RAGE) is involved in inflammatory pathogenesis. It functions as a receptor to multiple ligands such as AGEs, HMGB1 and S100 proteins, activating multiple intracellular signaling pathways with each ligand binding. The molecular events by which ligand-activated RAGE controls diverse signaling are not well understood, but some progress was made recently. Accumulating evidence revealed that RAGE has multiple binding partners within the cytoplasm and on the plasma membrane. It was first pointed out in 2008 that RAGE’s cytoplasmic tail is able to recruit Diaphanous-1 (Dia-1), resulting in the acquisition of increased cellular motility through Rac1/Cdc42 activation. We also observed that within the cytosol, RAGE’s cytoplasmic tail behaves similarly to a Toll-like receptor (TLR4)-TIR domain, interacting with TIRAP and MyD88 adaptor molecules that in turn activate multiple downstream signals. Subsequent studies demonstrated the presence of an alternative adaptor molecule, DAP10, on the plasma membrane. The coupling of RAGE with DAP10 is critical for enhancing the RAGE-mediated survival signal. Interestingly, RAGE interaction on the membrane was not restricted to DAP10 alone. The chemotactic G-protein-coupled receptors (GPCRs) formyl peptide receptors1 and 2 (FPR1 and FPR2) also interacted with RAGE on the plasma membrane. Binding interaction between leukotriene B4 receptor 1 (BLT1) and RAGE was also demonstrated. All of the interactions affected the RAGE signal polarity. These findings indicate that functional interactions between RAGE and various molecules within the cytoplasmic area or on the membrane area coordinately regulate multiple ligand-mediated RAGE responses, leading to typical cellular phenotypes in several pathological settings. Here we review RAGE’s signaling diversity, to contribute to the understanding of the elaborate functions of RAGE in physiological and pathological contexts.

抄録 Although recent retrospective studies suggested that the use of β-blockers appears to help improve the mortality rate and decrease the rate of exacerbation in chronic obstructive pulmonary disease (COPD) patients with heart failure, the effects of β-blockers on COPD patients without heart failure have not been established. Based on previous reports, we have launched a multicenter, prospective, single-arm phase II study to evaluate the preventive effect of the cardioselective β-blocker bisoprolol in COPD exacerbation, in Japanese individuals with moderate-to-severe COPD who do not have heart failure but do have hypertension requiring the use of medication. The primary endpoint is the rate of mild-to-severe COPD exacerbation. The results of this study will clarify whether bisoprolol can prevent exacerbation in COPD patients without heart failure.

抄録 We describe a 40-year-old living-donor renal-transplant recipient who underwent successful ureterolithotripsy. He had been on hemodialysis for >15 years pre-transplant and underwent ureteroureterostomy along with the surgery. One year post-transplant, ultrasound examination demonstrated hydronephrosis, and CT showed a 6-mm ureteral calculus at the ureteroureterostomy site. No pain and no elevated serum creatinine were present. As the ureter was easily accessed, we performed a ureterolithotripsy, which would confirm whether a suture caused the calculus. Despite ureteral tortuosity, laser stone fragmentation succeeded. The calculus was completely removed with an antegrade guidewire. Mild postoperative ureteral stenosis resolved with a temporary ureteral stent without balloon dilation. Ureterolithotripsy is effective even in renal transplant recipients with ureteroureterostomy.

抄録 We herein present a case of a 38-year-old man who had bamboo spine and severe sacroiliitis and who was diagnosed with ankylosing spondylitis (AS). Infliximab (IFX) markedly improved the axial symptom but was discontinued due to the side effect of peripheral neuropathy. Switching from IFX to etanercept worsened the side effect. Rituximab (RTX) administration elicited a good response without side effects. RTX might be a suitable option for AS therapy when TNF inhibitors are difficult to use.

抄録 The rare developmental defect, Goldenhar syndrome is characterized by complex craniofacial and dentofacial anomalies. Here we describe the successful orthodontic treatment of a 5-year-old Japanese Goldenhar syndrome patient with mild facial asymmetry, right microtia, right-side hearing loss, and tongue-thrusting by a modification of dentofacial growth using a non-surgical orthopedic treatment approach. Improvement of the vertical discrepancies on the affected side and canted occlusal plane as well as mandibular deviation were achieved with a functional orthopaedic approach. Stable and acceptable occlusion were obtained over the 32-month post-retention period. A non-surgical orthodontic treatment approach offers satisfactory facial aesthetic outcomes in Goldenhar syndrome.

抄録 We investigated the genetic mechanisms underlying the association between human leukocyte antigen (HLA) types and the immune response to hepatitis B virus (HBV) vaccination in 84 healthy Japanese adults, and found that the HLA-DRB1*04 and HLA-DQB1*03 frequencies were higher in the low responders (<10 mIU/ml; n=9, 10.7%) compared to the responders (≥10 mIU/ml, n=75, 89.3%). The combination of DRB1*04 and DQB1*03 was associated with a low response to vaccination. The DRB1*04 and DQB1*03 haplotypes’ frequencies were significantly higher in the low responders compared to responders. Novel candidate HLA types may be important in Japanese individuals.

抄録 Cervical spine dislocation and fracture of a transverse process are isolated risk factors for vertebral artery injuries (VAIs), which can cause a life-threatening ischemic stroke. Since in vivo experiments are not possible, it has not been unclear whether damage to or extension of vertebral arteries is more predictive of a VAI. To identify the imaging characteristics associated with VAI, we analyzed 36 vertebral arteries from 22 cervical spine dislocation patients who underwent computed tomography angiography (Aug. 2008-Dec. 2014). We evaluated (1) the posttraumatic elongation of the vertebral artery and (2) the presence of fracture involving the transverse foramen. VAI was found in 20 (56%) of the 36 vertebral arteries. The rate of residual shift (vertebral artery elongation) was not markedly different between the VAI and no-VAI groups. However, the rate of >1 mm displacement into the foramen and that of fracture with gross displacement (≥2 mm) differed significantly between the groups. We found that greater displacement of fractured transverse processes with cervical spine dislocation was a risk factor for VAI. These results suggest that direct damage to the vertebral arteries by transverse process fragments is more likely to predict a VAI compared to elongation, even in cervical spine dislocation.

抄録 To identify predictive factors for conversion from laparoscopic cholecystectomy (LC) to open cholecystectomy performed for mixed indications as an acute or elective procedure. We retrospectively analyzed the data of 236 consecutive cases of LC performed in our department between January 2012 and January 2015, and evaluated preoperative risk factors for conversion and the usefulness of the 2013 Tokyo guidelines (TG2013) for diagnosing acute cholecystitis. The conversion rate in our series was 8% (19/236 cases). The following independent predictive factors of conversion were identified (p≤0.04): previous upper abdominal surgery (odds ratio (OR), 14.6), pericholecystic fluid (OR, 10.04), acute cholecystitis (OR, 7.81), and emergent LC (OR, 15.8). Specifically for patients with acute cholecystitis defined using the 2013 Tokyo guidelines, use of an antiplatelet or anticoagulant drug for cardiovascular disease (p=0.043), previous upper abdominal surgery (p<0.031) and a resident as operator (p=0.041) were predictive factors. The risk factors for conversion identified herein could help to predict the difficulty of the procedure and could be used by surgeons to better inform patients regarding the risks for conversion. The TG2013 can be an effective tool for diagnosing acute cholecystitis to make informed clinical decisions regarding the optimal procedure for a patient.
