Yosuke Tamasaki, Hironobu Ueshima, Sakatoshi Yoshiyama, Satoshi Higuchi, Hiroshi Otake
Open Journal of Anesthesiology (OJAnes) , 2019, DOI: 10.4236/ojanes.2019.94006
Abstract: Background: An ear-fitting thermometer probe “NIPRO CE THERMO?” (Nipro Corporation, Osaka, Japan, new CE thermo) for both ears was newly developed in 2017. Since new release, we have never investigated about an accuracy of the new CE thermo. In this time, the accuracy of the CE thermo was investigated. Methods: The correlation between the tympanic membrane temperature, measured using the new CE thermo, and the esophageal temperature of 30 patients (right ear: 16 patients, left ear: 14 patients) was measured in the prospective observational study. Results: A good correlation (r = 0.721) and no measurement error (within 1?C in mean ± 2SD) between the two temperatures were observed using Bland-Altman analysis. The correlation and measurement error for each ear yielded the same results. Conclusion: The tympanic membrane temperature, measured using the new CE thermo, showed good correlation with the esophageal temperature and could be used as a central temperature in the perioperative period.

Keisuke Suzuki, Masaya Niitsu, Tomohiko Kamo, Satoshi Otake, Yusuke Nishida
Open Journal of Therapy and Rehabilitation (OJTR) , 2019, DOI: 10.4236/ojtr.2019.73005
Abstract: Background: Diabetic peripheral neuropathy (DPN) changes leg muscle coordination during walking and reduces stability. The aim of this study was to determine whether rhythmic auditory stimulation (RAS) affected the gait performance of patients with DPN. Methods: Forty DPN patients (mean age, 59.1 ± 9.4 y) were randomly allocated to RAS and control groups in equal numbers. The participants in each group underwent 2 weeks of supervised rehabilitative treatment (40 min/day) as inpatients. This included walking twice a day, during which the RAS group participants walked in time with a metronome set at a self-chosen, comfortable rate. We compared gait function, lower limb muscle co-contraction, and gait stability before and after the intervention for both groups, calculated the change in score for each parameter, and assessed differences between the groups with unpaired t-tests and ANCOVA. Results: RAS was associated with significant improvement in all parameters. In the control group, there was no improvement in cadence, co-contraction, or gait stability (vertical). Compared with the control group, the RAS group showed improvement in co-contraction and gait stability. Conclusion: RAS may be helpful for improving the lower limb muscle coordination and gait function of DPN patients.
Focused Review: Efficacy of the Rector Spinae Plane Block  [PDF]
Hironobu Ueshima, Hiroshi Otake
Open Journal of Anesthesiology (OJAnes) , 2018, DOI: 10.4236/ojanes.2018.87022
Abstract: Since the original publication on the erector spinae plane (ESP) block in 2016, the technique of the ESP block has evolved significantly in the last few years. This review highlights recent developments in the technique for administering the ESP block and proposes directions for future research. Continuous efforts are being aimed at improving understanding regarding the administration of the ESP block. Current reports suggest that the ESP block provides effective analgesia in thoracic and abdominal sites in patients of all ages. However, no cohort studies or randomized controlled trials were performed in 2016 and 2017. The ESP block is an effective analgesic tool in a wide range of sites. However. We are uncertain how effective the ESP block is compared to other types of regional anesthesia. Therefore, more research on ESP blocks is required.
A Dependence of Crystallinity of In2O3 Thin Films by a Two-Step Heat Treatment of Indium Films on the Heating Atmosphere  [PDF]
Yuichi Sato, Fumito Otake, Hirotoshi Hatori
Journal of Modern Physics (JMP) , 2010, DOI: 10.4236/jmp.2010.16051
Abstract: A difference in crystallinity of In2O3 thin films on sapphire substrates by heat treatment of indium films was reported. Indium films were heated in an inert atmosphere or in air until they reached a specified temperature and then oxidized in air at much higher temperatures. Crystallinity of the In2O3 thin film which was heat-treated in air from room temperature was quite poor. On the other hand, narrow X-ray rocking curves of the In2O3 films were obtained when the temperature was increased in an inert atmosphere to a specified tem-perature.
Stereo-Selective Synthesis of 5-Norbornene-2-exo-carboxylic Acid—Rapid Isomerization and Kinetically Selective Hydrolysis  [PDF]
Miki Kanao, Atsushi Otake, Kousuke Tsuchiya, Kenji Ogino
International Journal of Organic Chemistry (IJOC) , 2012, DOI: 10.4236/ijoc.2012.21005
Abstract: Simple and efficient stereo-selective synthesis of exo-5-norbornene-2-carboxylic acid (NBCA) is reported. Preliminary studies on base promoted isomerization of methyl 5-norbornene-2-carboxylate (MNBC) revealed that rapid isomerization was accomplished with sodium tert-butoxide (tBuONa), and the exo-content at the equilibrium was ca. 60%. The hydrolyses of endo-rich MNBC (endo/exo = 80/20) under various conditions were carried out. The exo selectivity for resulting NBCA was improved when the hydrolysis was conducted with equimolar water at room temperature in the presence of the stronger base (tBuONa) (endo/exo: 18/82). Whereas the use of excess amount of water led to rapid and non-selective hydrolysis affording high endo content of the product. The plausible reaction mechanism involving rapid equilibrium of thermodynamic isomerization and kinetically preferred hydrolysis of exo ester is proposed.

Keiichi Uchida, Mikihiro Inoue, Kohei Otake, Yuhki Koike, Masato Kusunoki
Open Journal of Pediatrics (OJPed) , 2013, DOI: 10.4236/ojped.2013.32010

Background: This study aimed to survey the use of complementary and alternative medicine (CAM) therapies in Japanese children with major pediatric surgical diseases. Methods: This survey was mailed to each family of 355 patients. Results: One hundred fifty-three (43%) of 355 mailed questionnaires were completely returned. Forty-one (27%) of 153 parents responded that they used CAM for their child. There was no significant difference in CAM use according to sex, mean age, follow-up duration, family CAM users, and associated disorders between CAM users and non-users. Children with inflammatory bowel disease (IBD) were significantly more likely to use CAM than children without IBD (65% vs 21%, p = 0.0001). Only 20% of parents informed the attending physicians about CAM before its use. Conclusions: It is important for physicians caring for children with pediatric surgical disease, especially IBD, to be familiar with common forms of CAM.

Growth of Graphene Nanocoil in a SiC Container: A Molecular Dynamics Study  [PDF]
Swastibrata Bhattacharyya, Shotaro Otake, Shota Ono, Riichi Kuwahara, Kaoru Ohno
Advances in Materials Physics and Chemistry (AMPC) , 2016, DOI: 10.4236/ampc.2016.65012
Abstract: Graphene nano structures find their application in modern nano electronics because of their excellent mechanical, unique electronics and electrical properties owing to the ballistic transport, where the charge carriers can move freely without getting scattered. In this work, we show a possibility to grow a miniaturised coil from a pre-existing graphene coil layer using molecular dynamics simulation. From our calculations it was observed that isolated carbon atoms get attached to the edge of the initial graphene coil and form an extension of the coil structure. The growth process depends strongly on the chirality of the growth front as well as the growth temperature. An optimal temperature between 2000 - 2300 K was proposed for all the edge structures except armchair (2500 K) type for the maximum number of the new hexagonal rings. Our results predict a technique that can be adopted experimentally to grow graphene nanocoil.
Regardless of the Puncture Angle, a Tuohy Needle with Sand-Blasted Steel at the Tip of the Bevel Is a Valid Needle on the Ultrasonic Images  [PDF]

Open Journal of Anesthesiology (OJAnes) , 2016, DOI: 10.4236/ojanes.2016.67017
Abstract: Background: A high ability to visualize the needle on the ultrasonic images is necessary to perform the ultrasound-guided nerve block safely. The Rafa Tuohy needleR (Vygon, Paris, France, Rafa) is a non-stimulating Tuohy needle with sand-blasted steel at the tip of the bevel. We examined the degree to which the Rafa enhanced the visibility of ultrasonic images compared with the non-coated Tuohy needle. Methods: We punctured the Blue Phantom. The dimensions of both the Rafa and the non-coated Tuohy needles were 18 G × 80 mm. The puncture angle is 30 degrees and 45 degrees from the Blue Phantom. We measured the intensity of the tip of the bevel at a depth of 0.5, 1.0, 1.5 and 2.0 cm for the puncture angle of 30 degrees, and 0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 cm for the puncture angle of 45 degrees. Six anesthesiologists with more than seven years of experience performed three punctures using each needle. Results: As an outcome, we concluded that at a puncture angle of both 30 degrees and 45 degrees, the intensity of the non-coated Tuohy needle decreased with the depth. On the other hand, at an angle of 30 degrees, the intensity of the Rafa needle did not decrease, and at an angle of 45 degrees the intensity only decreased very slightly as the depth increased. Conclusions: The Tuohy needle with sand-blasted steel at the tip of the bevel provided greater visualization than the non-coated Tuohy needle on the ultrasound images.

Ichikawa Yuki, Hironobu Ueshima, Hiroshi Otake, Akira Kitamura
International Journal of Clinical Medicine (IJCM) , 2017, DOI: 10.4236/ijcm.2017.83019
Abstract: We investigated the efficacy of ultrasound-guided pectoral nerves (PECS) block for modified radical mastectomy surgery retrospectively. Methods: We measured that pain scores and the use of additional analgesic drugs were recorded in the postoperative care unit within 24 hours after the operation. Postoperative complications (i.e., nausea and vomiting) were noted. Results: Patients who received the PECS block under general anesthesia (PECS group) reported lower visual analog scale pain scores at 0, 1, 2, 4, 6, 12, 24 hours after the operation than patients who did not receive PECS block under general anesthesia (control group). Moreover, the use of additional analgesic drugs during the first 24 hours after surgery was lower in the PECS group than in the control group. While in the postoperative care unit, the PECS group had less nausea and vomiting than the control group. Conclusion: The PECS block provides effective postoperative analgesia within the first 24 hours after breast cancer surgery.

Abstract: Background: Pectoral nerves (PECS) block has been reported to be effective for a perioperative analgesia for breast cancer surgery. In addition, we may consider that the PECS block is also effective for motor function in postoperative period. Therefore, we investigated the effect of PECS block for motor function in postoperative period. Methods: This study selected the patients performed the breast cancer surgery between April and September, 2015. The study surveyed the difficulty of movement of the upper limbs at postoperative day 5 (D5) and postoperative month 6 (M6) by performing telephone survey. We counted the number of patients who complained of the difficulty of movement of the upper limbs. All results were compared using the chi- squared test. P < 0.05 was considered statistically significant. Results: 93 patients received only general anesthesia (G group). 85 patients received PECS block with general anesthesia (P group). The number of the P group at D5 was 2 patients. On the other hand, the number of the G group was 15 patients (P = 0.042). In the same way, the number of the P group M6 was no patient. On the other hand, the number of the G group was 10 patients (P = 0.043). Conclusion: A PECS block is effective for motor function recovery in the early postoperative period after breast cancer surgery.
