A recently developed real-time computed tomography (CT) fluoroscopy system, which provides effective reconstruction and display of CT images, was used to monitor nonvascular interventional procedures performed in 57 patients. Biopsy thoracic lesions (n = 38), biopsy or drainage pelvic 6), aspiration intracranial hematomas 9), other 4) were performed. successfully depicted the entire procedure all In lesions, a mean 1.3 passes necessary gain access lesion. Sufficient cytologic samples...
Ultrasound-guided quadratus lumborum block is a regional anesthetic technique which can provide perioperative analgesia for all age groups, including pediatric patients undergoing abdominal surgery. We hypothesized that the would be as efficacious caudal block, gold standard of lower anesthesia, in providing pain control after ureteral reimplantation but also have longer duration.Forty-seven between ages 1 and 17 years bilateral surgery via low transverse incision were enrolled randomized...
We investigated the relationship of lymph node metastasis to primary tumor size and microscopic appearance in 92 resected specimens obtained from patients with roentgenographically occult lung cancer (ROLC) located at a site along airway between main bronchus sub-subsegmental bronchi. Most were discovered by mass screening. All treated surgically after bronchoscopic localization cancer. The bronchial tree was serial-sectioned into 2-mm thick blocks margin resection Bronchial wall invasion...
Object. The authors assessed the diagnostic value of 201 Tl Cl single-photon emission computerized tomography (SPECT), performed after gamma knife surgery (GKS) for metastatic brain tumors in differentiating tumor recurrence from radiation injury. Methods. Of 6503 treated with GKS, SPECT was required 72 to differentiate between and When index greater than 5, lesion diagnosed as a recurrence. < 3.0 it called In cases 3 repeated once per month until 5 or less 3. If fluctuated 2 months,...
Diffusion-weighted imaging (DWI) is a functional technique based on the ability to depict movement of water molecules. The magnitude molecule expressed as apparent diffusion coefficient (ADC) value. Its usefulness in diagnosis malignant tumors has gained interest. purpose this study was evaluate DWI detecting lymph node metastases colorectal cancer. subjects were 46 consecutive patients (mean age 71.4 ± 8.7 years) with cancer, treated by radical surgery from 2006 2008. size metastatic nodes...
Transient postoperative urinary incontinence is a bothersome complication of holmium laser enucleation the prostate (HoLEP). The effects preoperative pelvic floor muscle exercise (PFME) for early recovery continence after HoLEP have never been elucidated. aim this study was to determine benefit preoperatively started PFME HoLEP.We randomly assigned patients start and continue postoperatively (group A) or no earlier than period B). primary outcome time complete control, defined as pad usage....
Object The authors prospectively analyzed volume changes in vestibular schwannomas (VSs) after Gamma Knife surgery (GKS). Methods Among 104 VSs treated by GKS at the Chiba Cardiovascular Center between 1998 and 2004, 87 consecutively unilateral observed on follow-up MR imaging for least 5 years were analyzed. These lesions harbored 31 men 56 women, with a mean age of 58.6 (range 29–80 years). Gd-enhanced each lesion was measured serially every 3 months during 1st year 6 thereafter using...
ABSTRACT In this study, we developed a shear and cooling milling machine (SCMM) to investigate the continuous mechanochemical treatment of starch with maleic acid. The temperature upper metal millstone, referred as SCMM, was maintained at 10°C by chiller flow. Corn acid (MA) were dry‐blended treated in SCMM repeatedly. effects repetition analyzed using Fourier transform infrared spectroscopy, wide‐angle X‐ray diffraction measurement, scanning electron microscopy. reaction between corn MA...
[Purpose] The purpose of this study was to clarify the benefits early mobilization for mechanically ventilated patients their survival discharge home from hospital. [Subjects and Methods] Medical records were retrospectively analyzed who satisfied following criteria: age ≥ 18 years; performance status 0-2 independent living at before admission; mechanical ventilation more than 48 h; after ventilation. Mechanically in (EM) group (n = 48) received therapy, limb exercise chest physiotherapy,...
ABSTRACT Purpose We examined the feasibility of using a head‐mounted display (HMD) to improve ergonomics sonographic‐guided interventional procedures. Methods Five physicians with experience more than 20 central venous catheterizations participated in this study. Each participant performed five pairs simulated jugular vein catheterization under sonographic guidance and without HMD. The procedure time was determined as well number head movements, needle redirections, posterior wall punctures,...
Objective To determine the safety and efficacy of one‐surgeon basketing technique for stone extraction during flexible ureteroscopy when carried out by novice surgeons under instructor guidance. Methods We retrospectively compared perioperative results, complications “stone‐free” rate (defined as ≤2 mm fragments on kidney–ureter–bladder imaging 1 month after ureteroscopy) between experienced (group A, n = 50) B, using technique. Results Baseline patients’ characteristics were similar two...
Abstract Background The caudal epidural block is one of the most commonly used regional anesthetic techniques in children. Administration morphine via injection enables analgesia, even for upper abdominal surgery. thoracic paravertebral has also been successfully to treat perioperative pain during procedures pediatric patients. Aim In current study, we compared two surgery infants determine whether them was preferable other. Methods Consecutive patients under 12 months age who underwent were...
Holmium laser enucleation of the prostate (HoLEP) has been a widely utilized minimally invasive surgical procedure for benign hyperplasia. The current study aimed to compare outcomes and King's Health Questionnaire (KHQ) assessment scores following HoLEP between younger men those aged ≥75 years.This prospective single-center compared perioperative complications, postoperative urinary conditions, KHQ (nine categories) years (group A) <75 B) before 1, 3, 6 months after surgery.A total 100...

Hemophagocytic lymphohistiocytosis (HLH), which is associated with various underlying conditions, characterized by hypercytokinemia. Because it frequently lethal, immediate mitigation of the hypercytokinemia vital to save patients, particularly when treatments for patient's condition are ineffective on HLH. We herein present a case Hodgkin lymphoma HLH in did not improve even after chemotherapy. attempted patient using hemoperfusion polymyxin B-immobilized fiber column remove cytokines;...
Objectives. To evaluate 24-hour intraocular pressure (IOP) variation in patients with primary open-angle glaucoma (POAG) treated triple eye drops. Subjects and Methods. The IOP was measured 74 eyes POAG (seated) on therapy (PG analogue, β -blocker, carbonic anhydrase inhibitor) at about every 3 hours. Results. peak 13.5 ± 3.1 1:00, the trough 12.6 2.4 mmHg 7:00. 7:00 significantly lower than that 10:00, 3:00 (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Objectives To assess the impact of patients’ interest in sex on satisfaction after robot‐assisted radical prostatectomy, longitudinal changes urinary and sexual functions bothers were evaluated. Methods A total 101 patients underwent prostatectomy our institution. Based interest, they divided into high‐interest low‐interest groups. Overall satisfaction, function, bother, bother evaluated using expanded prostate cancer index composite questionnaire preoperatively at 1, 3, 6, 12 months...
