Abstract

A Pixel Circuit and a Gate Driver on Array for light‐emitting display are presented. By simultaneously utilizing Top‐Gate n‐type Oxide and p‐type LTPS TFTs, the circuits provide high refresh rate and low power consumption. An AMOLED panel with proposed circuits is fabricated and driving at various refresh rate ranging from 1Hz to 120Hz could be achieved.

Author

Sonoda, Tohru, Murashige, Shogo, Tanaka, Kohhei, Takase, Kenji, Katoh, Hiromi, Kataoka, Yoshiharu, Usui, Takenobu, Okada, Takuya, and Shimizu, Takahisa

Abstract

In this work, we report 30‐inch 4K rollable AMOLED display, featuring IGZO‐TFT backplane and side by side evaporation process with etching fine metal mask. Adaptive temporal aperture control is used to improve motion image quality. Roll‐up mechanics have various parts to get its flatness, quietness and stability. Finally, we demonstrate a large rollable display, showing motion images clearly and rolling up compact with a radius of 20 mm.

Abstract

99mTc-DMSA腎摂取率の再現性を健常成人で評価し, 1側の腎結石に対し, ESWLまたはPNLを施行した48症例で, 治療前後にDMSA腎シンチグラフィを施行し, 治療法の腎機能への影響を検討した。健常成人では99mTc-DMSA腎摂取率は再現性は保たれているが, 数%の変動がみられた。ESWL群, PNL群または両者併用群において治療前後で治療側腎摂取率には有意な変化はみられなかった。各群間を比較すると, PNL群および両者併用群とESWL群との間に有意な差が認められた(p, 99mTc-DMSA renal scintigraphy was utilized to investigate the influence of ESWL on renal function in comparison with that of PNL. In the beginning, the reproducibility of renal uptake rate by the scintigraphy was examined in eleven healthy volunteers under both non-diuretic and diuretic states. The renal uptake rate was shown to be sufficiently reproducible in the same person in the two different trials. However, the differences and the standard deviations were shown to be a few percentages, which were not statistically significant. Changes in the repeated renal uptake rate seem to indicate not only changes of renal function with the treatment but also some technical errors. Herein, to investigate changes in renal function of the therapeutic side, the uptake ratio rate (rate of uptake rate in the therapeutic side/uptake rate in the contral lateral side) was utilized instead of uptake rate. Renal scintigraphy was carried out in 48 patients with unilateral renal stones before and after ESWL or PNL monotherapy or the combined ESWL and PNL therapies. Within one week of treatment, the uptake ratio rate significantly decreased in patients with PNL or the combined ESWL and PNL, although DMSA uptake rate in the therapeutic side did not significantly changes. Neither renal uptake rate nor uptake ratio rate significantly changed after ESWL treatment. There was no significant difference in changes of uptake ratio rate between Siemens Lithostars Plus and the improved Dornier HM-3 lithotriptors. This study indicated that ESWL monotherapy did not affect the uptake ratio rate, although PNL monotherapy and the combined ESWL and PNL therapies may affect the uptake ratio rate to some extent.

Abstract

A case of ipsilateral pelvic transitional cell carcinoma and renal cell carcinoma (RCC), in an 82-year-old male is presented. We diagnosed this case as pelvic tumor preoperatively with retrograde pyelography and computed tomography. Operatively renal tumor was found and diagnosed as RCC. We thought it difficult to diagnose as RCC preoperatively. To date, this case is the 13th reported case diagnosed clinically.

Abstract

The case of a patient who might have developed nasogastric tube syndrome at the end of anesthesia is presented. A 62-year-old woman was scheduled for a general anesthesia with fiberscopic oro-tracheal intubation because of a predicted difficult airway. After the smooth and gentle intubation without any trauma and injury, a nasogastric tube was inserted blindly. At the end of surgery, the anesthesiologists observed the pharyngeal tissue and found significant edema on the epiglottis and arytenoids. Extubation was cancelled and the patient was moved to an intensive care unit for respiratory management. On the next day, fiberscopic observation revealed a complete recovery and the endotracheal tube was removed without any difficulty. We strongly suspected the pharyngeal injury as acute nasogastric tube syndrome and an attention to this rare complication is required by anesthesiologists.

Abstract

We describe a case of marked swelling of the tongue in a patient after a long prone position neurosurgery, who was treated for hypertension with alacepril. The tongue was not congestive and history of taking an angiotensin-converting enzyme inhibitor suggested an alacepril-induced angioedema. The day after surgery, the patient's tongue was still swollen; however, fibrescopic observation of the larynx and pharynx through the nasal cavity revealed that the edema was limited to anterior tongue, and the oral cavity and oropharynx were not involved. Although, tongue angioedema was observed, we introduced a 3-mm tube exchanger to the patient's trachea and removed the endotracheal tube. The ventilation and oxygenation were maintained, and 30 min later, the exchanger was detached. On the second postoperative day, the angioedema disappeared completely and the patient was transferred to a ward without any complication.

Abstract

Cold agglutinin (CA) reacts reversibly with red blood cells at a low temperature and may cause thromboembolism of various organs. Therefore, special consideration is required in patients with cold agglutinin disease (CAD) undergoing cardiovascular surgery requiring hypothermia. Case 1: A 71-year-old man with elevated CA was scheduled to undergo total aortic arch replacement. Preoperatively, the patient received double filtration plasmapheresis to reduce CAs. The operation was performed at a higher temperature than the patient's thermal amplitude (TA) of 30 degrees C. Case 2: A 72-year-old man with CAD underwent a coronary artery bypass grafting. The patient's TA was 32 degrees C. The operation was performed on the beating heart with normothermic cardiopulmonary bypass. We performed an agglutination test at the temperature of 24 degrees C using the blood sample from the cardiopulmonary bypass circuit and no signs of agglutination were found. In both cases, no symptom of microembolism due to cold agglutination was recognized. This may indicate the possibility that the clinical risk is smaller than the risk recognized in vitro analysis. However, no safety standards for perioperative management of patients with CA are clearly established. Generally, it is more important to figure out the TA and to prevent the low-temperature exposure below the TA. In cases of normothermic procedures, further consideration for cerebral and myocardial protection is important.
