It is known that cochlear implantation for deaf patients with eosinophilic otitis media (EOM) is safe and can provide good speech perception. However, the best timing of implant surgery in patients with EOM is not yet known. The aim of this case report is to suggest the appropriate timing of the surgery in EOM patients with deaf. Cochlear implantation was indicated in two patients with EOM. One underwent cochlear implantation in the absence of any ear discharge. In the other case, implant surgery was delayed for three years due to persistent ear discharge. No complications related to implant device or skin flap were observed in either case. The speech recognition score after implantation was good in the first case and poor in the second case. Perioperative complications were manageable even in the patient with persistent ear discharge. However, the delay in implant surgery due to the persistent ear discharge resulted in a poor speech recognition score. Early implantation should be considered even in EOM patients with ear discharge, although the presence of active middle ear inflammation is regarded as one of the contraindications for implantation according to the current Japanese guidelines.

Preoperative echography of a saphenous vein graft (SVG) was studied. In 58 cases of consecutive coronary artery bypass grafting, 31 patients underwent SVG echography. Preoperative assessment revealed vein caliber, branching, or varicose saphenous veins. The location of the saphenous vein was marked. Saphenous veins were harvested by the open harvest technique, and the caliber of the veins and the availability of the anastomosis device were recorded. Postoperative morbidity was recorded. Preoperative findings revealed that four (6.5%) of 62 femoral saphenous veins were estimated as “not graftable” because of being a varicose vein or having a small caliber. Seven of 32 lower saphenous veins were estimated as “not graftable”. The mean discrepancy of the caliber was 0.6 mm undersized with preoperative estimation. During harvesting, one of 31 patients had a wrong marking. We were able to use all harvested veins. The morbidity of saphenous harvesting was observed in two (6.5%) of 31 patients. One patient whose marking was wrong had minor skin necrosis. Another patient experienced a hematoma because of the excess effect of warfarin. Preoperative ultrasonic mapping of the saphenous vein reduced useless harvesting, provided information concerning anastomosis device availability, and seemed to reduce morbidity because dissection can be minimal.

Background: Liquid-based cytology (LBC) is a method of manufacturing cyto-diagnostic specimens. Improved accuracy is expected from standardizing specimen production and use of this method is rapidly spreading in oral cytology. On the other hand, LBC reportedly requires training to show peculiar cell findings compared to those of conventional smear cytology (CVC). Few studies have compared detailed cell findings for oral CVC and LBC. Objectives: The aim of this study was to compare cytological findings between CVC and LBC using cytomorphological image analysis. Materials and Methods: Cytological specimens were collected from 20 patients (negative for squamous neoplasia in 10, dysplasia in 5, squamous cell carcinoma in 5) and 5 controls of the tongue between January 2017 and December 2018. Two different preparation techniques were investigated cytomorphologically for CVC and LBC (BD CytorichTM). Results: LBC showed significantly higher cell numbers than CVC for all lesions. LBC-to-CVC ratio ranged from 9.52 (hyperkeratosis) to 1.87 (deep cells in oral squamous cell carcinoma (OSCC)). Nuclear area of normal, hyperkeratosis, and inflammation were significantly higher in LBC than those of CVC. Hyperchromasia was significantly more frequent with CVC than with LBC for hyperkeratosis, inflammation, dysplasia and OSCC. There was no significant difference in circularity between CVC and LBC among all lesions. Conclusion: Only one cytomorphological disadvantage was seen with LBC, in the form of decreased hyperchromasia. Further clarification of the advantages and disadvan

Wind-driven power harvestings attract attentions since their target wind speeds are quite low less than the so-called cut-in wind speed, which is generally recognized as around 3 m/s. The extant power harvestings driven by wind-induced-air-column-resonations (i.e. acoustic-pressures) are still lacking simplicity, scale flexibility and solid strategies for practical applications. Therefore, the piezoelectric power harvesters via acoustic-pressures driven by low-speedwind-forces with resonating-tubes and wind-collectors were invented so as to complement all the lacks. The wind-collector as well as the resonating-tube contributed to upraise the power harvesting density. The champion power harvesting density of 19.5 nW/dm2 could be procured at 2.3 m/s of an artificial wind and the optimal resonating-tube and wind-collector. Power harvesting proofs from the natural wind with low mean speeds down to about 0.6 m/s were successfully obtained. The cut-in wind speed of the prototype piezoelectric power harvester was found to be quite low as about 0.4 m/s, signifying its ubiquity. Finally, a multi-bundle pendant-type piezoelectric power harvester was specifically presented together with professing the solid and multiple strategies for practical applications.

＜正＞’Bright spots’ is an auroral feature well observed on postnoon auroral oval by satellite UV imageries. Because of strong atmospheric absorption on UV emissions, however, UV ’bright spots’ cannot be directly observed on the ground. All sky images obtained at Zhongshan in the Antarctic have been used to study the conjugate visible features of ’bright spots’ aurora in Polar UV images covering the northern oval. Two case studies shown for the first time that bright spots in satellite UVI might be associated with spirals along a bright arc aurora in all sky images. Ground observation on aurora spirals with high temporal and spatial resolution camera allowed us to clarify that bright spots might be of the scale of 10-100 km and last for less than 1 minute. Investigation with all-sky images indicates that UV bright spots might display same rotation sense as aurora spirals do, namely, counter-clockwise in magnetic field direction.

A left ventricular (LV) free wall rupture is a highly lethal condition. A 75-year-old female who experienced chest pain was diagnosed as having an acute aortic dissection Stanford type A and underwent emergent surgery. Under cardiopulmonary bypass with LV venting through the right superior pulmonary vein, a proximal aortic stamp was formed. The patient was cooled, selective antegrade brain perfusion was performed, and a hemiarch repair was performed. After the patient was transferred to the intensive care unit, her blood pressure suddenly fell to 50 mmHg. She had a blowout rupture in the left ventricular anterolateral free wall. Since the bleeding hall was not large and the damage to the surrounding left ventricular tissue was not very wide, an off-pump multilayered sutureless repair was performed by using three layers of collagen fleece squares with fibrinogen-based impregnation (TachoComb;CSL Behring, Tokyo, Japan) and three layers of gelatin-resorcin-formalin glue reinforced by an equine pericardial patch (Xenomedica;Edwards Lifesciences, LLC, Irvine, CA). The blow-out rupture seemed to be caused by perioperative myocardial infarction generated by the compression of the left ventricular vent to the LV lateral wall. The patient was free from re-rupture or aneurysm enlargement. The thickness of the hemostatic material seemed to help control the bulging of the aneurysm and to prevent further LV aneurysm enlargement and re-rupture.

A 73-year-old male patient with a 3-year history of hemodialysis was admitted for the treatment of pericardial effusion. Echocardiography suggested a diagnosis of effusive pericarditis. Pericardiocentesis was performed several times. Six weeks after the admission, the patient developed cardiac tamponade. Surgical pericardiotomy showed the epicardium had a diffuse shaggy and hemorrhagic surface. To control diffuse oozing, fibrin sealant patches (Tachosil;CSL Behring, Tokyo, Japan) were attached to the epicardium. Oozing was then controlled.
