Objective:To assess the incidence of asymptomatic unruptured renal artery pseudoaneurysm(RAP)on contrast-enhanced computed tomography(CE-CT)after robot-assisted partial nephrectomy(RAPN)without parenchymal renorrhaphy.Methods:From May 2016 to December 2017,78 patients underwent RAPN for renal tumors.Inner suture was performed in the opened collecting system or renal sinus,whereas parenchymal renorrhaphy was not.For hemostasis,the soft coagulation system was used,and absorbable hemostats were placed on the resection bed.CE-CT was carried out within 7 days after surgery.Data on these patients were prospectively collected.A single radiologist determined the diagnosis of RAP.Results:Median(range)data were as follows:Patient age,65(19-82)years;radiographic tumor size,30(12-95)mm;operating time,166(102-294)min;warm ischemic time,16(7-67)min;and blood loss,15(0-4450)mL.One patient(1.6%)required a perioperative blood transfusion.No patient required conversion to open surgery or nephrectomy.CE-CT was carried out at median 6(3-7)days after surgery.CE-CT showed no RAP development in all 61 patients.Urinary leakage was not observed.One patient had acute cholecystitis,a postoperative complication classified as Clavien-Dindo grade higher than 3,which was treated with cholecystectomy.Positive surgical margin was identified in four patients(6.6%).Conclusion:RAPN using soft coagulation and absorbable hemostats without renorrhaphy appears to be feasible and safe.Our technique could eliminate the risk of RAP.

Neural Regeneration Research 2020年第1期15卷 63-64页

作者： Fumihiro kawakita Hidenori Suzuki Department of Neurosurgery Mie University Graduate School of Medicine

Cerebrovascular diseases,which include ischemic and hemorrhagic strokes,remain serious conditions with high mortality and disability worldwide(He et al.,2018).Ischemic stroke accounts for around 80%of all strokes(He et al.,2018).Hemorrhagic stroke consisting of intracerebral hemorrhage and subarachnoid hemorrhage(SAH)occurs less frequently but may cause poorer outcomes than ischemic stroke(Ji et al.,2017;Luo et al.,2018).It is also well known that aneurysmal SAH may have delayed cerebral ischemia(DCI):thus aneurysmal SAH has both characteristics of hemorrhagic and ischemic strokes(Kanamaru et al.,2019).In spite of enormous efforts to improve outcomes,no conclusive treatment exists thus far,once stroke is completed.

Transition Behavior in the Use of Complementary and Alternative Medicine during Follow-up after Radical Prostatectomy: A Multicenter Survey in Japan

引用

Health 2010年第12期2卷 1460-1465页

作者： Koji Yoshimura Yoshiteru Sumiyoshi Toshiyuki Kamoto Osamu Ogawa Yoichi Arai Yoshiyuki Kakehi Akito Terai Hiroshi Kanamaru Mutsushi Kawakita Naoko Kinukawa Department of Urology Kyoto University Graduate School of Medicine Department of Urology Shikoku Cancer Center

We evaluated the prevalence of use of complementary and alternative medicine (CAM), as well as the transitional nature of its use, before and after radical prostatectomy in Japa-nese patients with localized prostate cancer. Methods: We enrolled 376 patients, who an-swered a self-administered questionnaire on CAM use, psychological health locus of control (HLC), and general-health-related quality of life (GHQL). Detailed information regarding CAM use according to the transtheoretical model, and the time at initiation and abandonment of CAM use were assessed. Medical information was also extracted from patient charts. Results: 45.7% of patients belonged to the “precontem-plation” stage, 29.8% to the “contemplation” stage, 1.9% to the “preparation” stage, 14.4% to the “action” stage, and 8.2% to the “relapse” stage. Although patient age and educational status had a significant impact on stage of CAM use, HLC and GHQL were not associated with them. The time-course of prevalence of CAM use during follow-up was divided into three phases: “initial,” “rapid-increase,” and “main-tenance”. Conclusions: Among patients under-going radical prostatectomy, non-users can be classified into several behavioral stages, while users do not use CAM constantly during fol-low-up.

Matricellular proteins as possible biomarkers for early brain injury after aneurysmal subarachnoid hemorrhage

引用

Neural Regeneration Research 2018年第7期13卷 1175-1178页

作者： Hidenori Suzuki Hirofumi Nishikawa Fumihiro kawakita Department of Neurosurgery Mie University Graduate School of Medicine

Aneurysmal subarachnoid hemorrhage remains devastating,and the most important determinant of poor outcome is early brain injury（EBI）.In clinical settings,as a surrogate marker of EBI,loss of consciousness at ictus,poor initial clinical grades,and some radiographic findings are used,but these markers are somewhat subjective.Thus,it is imperative to find biomarkers of EBI that have beneficial prognostic and therapeutic implications.In our opinion,an ideal biomarker is a molecule that is implicated in the pathogenesis of both EBI and subsequently developing delayed cerebral ischemia（DCI）,being a therapeutic target,and can be measured easily in the peripheral blood in an acute stage.A good candidate of such a biomarker is a matricellular protein,which is a secreted,inducible and multifunctional extracellular matrix protein.There are many kinds of matricellular proteins reported,but only tenascin-C,osteopontin,galectin-3 and periostin are reported relevant to EBI and DCI.Reliable biomarkers of EBI may stratify aneurysmal subarachnoid hemorrhage patients into categories of risk to develop DCI,and allow objective monitoring of the response to treatment for EBI and earlier diagnosis of DCI.This review emphasizes that further investigation of matricellular proteins as an avenue for biomarker discovery is warranted.

Leaching of phosphorus from incinerated sewage sludge ash by means of acid extraction followed by adsorption on orange waste gel

引用

Journal of Environmental Sciences 2009年第12期21卷 1753-1760页

作者： Biplob Kumar Biswas Katsutoshi Inoue Hiroyuki Harada Keisuke Ohto Hidetaka kawakita Department of Applied Chemistry Saga University

Ashes from sewage sludge incineration have a high phosphorus content, approximately 8% （W/W）, which indicates a potential resource of the limiting nutrient. Incineration of sewage sludge with subsequent recovery of phosphorus is a relatively new sludge treatment technique. In this article, the leaching of phosphorus by using sulfuric acid as well as hydrochloric acid by means of several batch experiments was presented. At the same time a selective recovery of phosphorus by adsorption was also discussed. The effects of acid concentration, temperature and time on extraction were studied. The phosphorus leaching increased with the increase in acid concentration and temperature. Kinetic studies showed that the complete leaching of phosphorus took place in less than 4 h. Selective adsorption of phosphorus by using orange waste gel provided a hint for recovery of this natural resource, which eventually could meet the ever-increasing requirement for phosphorus. The overall results indicated that the incinerated sewage sludge ash can be treated with acid to efficiently recover phosphorus and thus can be considered a potentially renewable source of phosphorus.

Invasive group B streptococcal infection in a patient with post splenectomy for hypersplenism secondary to liver cirrhosis and portal hypertension

引用

World Journal of Emergency Medicine 2016年第1期7卷 68-70页

作者： Tomoya Okazaki Toru Hifumi Arisa Manabe Hikari Matsumura Satoshi Egawa Hideyuki Hamaya Nastuyo Shinohara Koshiro Takano Hajime Shishido Yuko Abe Kenya kawakita Masanobu Hagiike Yasuhiro Kuroda Emergency Medical Center Kagawa University Hospital Kita Kagawa 761-0793 Japan

BACKGROUND:Splenectomy in patients with liver cirrhosis(LC)is expected to become more common owing to its efficacy on portal hemodynamics.In this report we describe an alarming case of group B streptococcus(GBS)infection after splenectomy in a patient with LC.METHODS:A 72-year-old woman with a history of LC was admitted to our emergency department because of respiratory failure.The patient had received left lateral segmentectomy of the liver and splenectomy three months before admission.Pulmonary examination revealed significant wheezing during inspiration and expiration,but no crackles and stridor.Chest radiography and CT showed no infiltrates.A presumptive diagnosis of bronchial asthma caused by upper respiratory infection was made.Four days after admission,GBS infection was confirmed by blood culture and penicillin G was administered.Antibiotics were given intravenously for a total of 12 days.RESULTS:The patient was discharged on the 12th day after admission.CONCLUSIONS:Although efficacy of splenectomy in patients with LC has been reported,immune status should be evaluated for a longer period.Patients who have undergone splenectomy are highly susceptible to bacteria;moreover,LC itself is an independent risk factor for mortality in patients with sepsis.Since prophylaxis against GBS has not been established,immediate action should be taken.Emergency physicians should be aware of invasive GBS infection in the context of the critical risk factors related to splenectomy and LC,particularly the expected increase of splenectomy performed in LC patients.

Open Journal of Stomatology 2014年第8期4卷 418-423页

Schwannomas originating from the hypoglossal nerve are extremely rare neoplasms. Hypoglossal schwannomas usually occur between the third and fifth decades of life, with no sex predilection, commonly presenting as a painless, slow-growing, and lateral neck mass. The best treatment is complete surgical excision with preservation of the neural pathway, if possible. In fact, since these tumors are almost always benign, a conservative surgical approach is emphasized by most authors. We report a case of a large schwannoma of hypoglossal nerve origin in the upper neck in a 31-year-old male. Magnetic resonance imaging of the area demonstrated a 43 × 39 × 36 mm well-circumscribed mass with high and nonhomogeneous signal intensity on the right side of the upper neck. The lesion was successfully treated by extirpation, with no recurrence. The extracranial hypoglossal nerve sheath was as the origin of this tumor because the patient experienced remarkable disturbance of tongue motility after surgery.

To clarify the characteristics of gas flow in high velocity oxy-fuel (HVOF) thermal spray gun, aerodynamic research is performed using a special gun. The gun has rectangular cross-sectional area and sidewalls of optical glass to visualize the internal flow. The gun consists of a supersonic nozzle with the design Mach number of 2.0 followed by a straight passage called barrel. Compressed dry air up to 0.78 MPa is used as a process gas instead of combustion gas which is used in a commercial HVOF gun. The high-speed gas flows with shock waves in the gun and jets are visualized by schlieren technique. Complicated internal and external flow-fields containing various types of shock wave as well as expansion wave are visualized.
