Study design: A retrospective, multicenter study.Objectives: To investigate the relationship between bowel and bladder management methods and symptomatic autonomic dysreflexia (AD) during hospitalization in patients with spinal cord injury (SCI).Setting: Twenty-eight Rosai hospitals in Japan.Methods: The study subjects were 571 patients with SCI who had been admitted to 28 Rosai hospitals between April 1997 and March 2007 for rehabilitation therapy and fulfilled the following criteria: (1) SCI at or above sixth thoracic level, (2) discharged from hospital after more than 4 months of admission for initial injury and (3) lack of pressure ulcers, deep venous thrombosis, ureteral and renal stones or heterotopic ossification throughout hospitalization to exclude possible influence of these complications on cardiovascular reflexes. The study subjects were examined for the incidence of symptomatic AD according to age, sex, ASIA Impairment Scale, injury level, bowel and bladder management techniques at discharge.Results: The Rosai Hospital registry included 3006 persons with SCI during 1997-2007, and 571 patients fulfilled the above criteria. The highest incidence of symptomatic AD was diagnosed in subjects using reflex voiding and in those using manual removal of stool. By contrast, the lowest incidence of symptomatic AD was in those on continent spontaneous voiding and continent spontaneous defecation.Conclusion: Medical staff should evaluate the presence of AD in patients with SCI at or above the T6 level under bladder and bowel management such as reflex voiding and manual removal of stool. © 2011 International Spinal Cord Society All rights reserved.

Interleukin-6 (IL-6) is produced by contracting skeletal muscles and then released into the circulation and considered to mediate the health benefits of exercise against chronic diseases. Individuals with spinal cord injury (SCI) are reported to be at higher risk of developing metabolic diseases. We investigated the IL-6 responses to 20-min arm crank ergometer exercise at 60% of maximum oxygen consumption in eight trained individuals with cervical SCI (CSCI) between C6 and C7, and eight able-bodied trained healthy subjects. The plasma concentrations of IL-6, adrenaline, prostaglandin E 2 and cortisol were measured before, immediately after the exercise, 1 and 2 h after exercise. At rest, the plasma adrenaline concentration was significantly lower in individuals with CSCI than in able-bodied subjects (P < 0.01). On the other hand, the concentration of IL-6 was significantly higher at rest in individuals with CSCI (2.18 ± 0.44 pg/ml, mean ± SEM) than the control (1.02 ± 0.22 pg/ml, P < 0.05). In able-bodied subjects, the plasma adrenaline concentration increased significantly immediately after the exercise (P < 0.01) and returned to the baseline level at 1 h after exercise, and the plasma IL-6 level increased significantly at 1 h after exercise (1.91 ± 0.28 pg/ml, P < 0.05) and returned to the baseline level at 2 h after exercise. In contrast, adrenaline and IL-6 levels were steady throughout the study in individuals with CSCI. The lack of exercise-related IL-6 response in individuals with CSCI could be due to muscle atrophy and sympathetic nervous system dysfunction. © 2011 Springer-Verlag.

Study design:Non-randomized study.Objective:The mechanism underlying exercise-induced argumentation of natural killer cell cytotoxic activity (NKCA) in humans remains unclear. To address this, NKCA responses were studied during and after exercise in persons with cervical spinal cord injury (CSCI) and dysfunctional sympathetic nervous system.Setting:Kibikogen Rehabilitation Center for Employment Injuries.Methods:We examined the NKCA responses to 20-min arm-crank ergometer exercise at 60% of maximum oxygen consumption in eight persons with CSCI (between C6 and C7) and six able-bodied subjects. NKCA, adrenaline, and cortisol were measured before, immediately after exercise, 1 h after exercise, and 2 h after exercise.Results:In able-bodied subjects, NKCA increased immediately after exercise (P<0.01) and then decreased to below the pre-exercise level 1 h after exercise, before recovering to the baseline level at 2 h after exercise. Plasma adrenaline concentrations increased significantly immediately after exercise (P=0.01) and returned to the baseline level 1 h after exercise. The plasma cortisol level did not change throughout the study. In contrast, NKCA, plasma concentrations of adrenaline, and cortisol did not change throughout the study in subjects with CSCI.Conclusion:In subjects with CSCI, the lack of response in NKCA throughout the experiment is probably mainly due to a dysfunctional sympathetic nervous system. © 2010 International Spinal Cord Society All rights reserved.

The positioning skill of the radiological technologist is essential for obtaining accurate diagnostic information of an organ and for reducing X-ray exposure in radiography. We previously reported on the development of a computed tomography (CT) image-based training tool. A three-dimensional phantom was produced by using computer graphics. Positioning was performed on a PC, and the plane image corresponding to the performed positioning was produced and displayed. In this study, the algorithm which produces the plane image from the CT image data was improved in order to obtain an image quality comparable to the X-ray image obtained by the Computed radiography (CR) system. The CT value and linear attenuation coefficient were calculated from the CT image data based on the fundamental interactions between X-rays and an object. By using the linear attenuation coefficient, a plane image with the same image quality as the CR image could be produced. © 2012 IEEE.

An appropriate and quick positioning technique is essential for obtaining accurate diagnostic information in radiography. In this study, a computed tomography (CT) image-based training tool which can assist the students is developed and the X-ray training method using CT images for positioning in radiography is proposed. First, from the CT image data of the phantom scanned beforehand, the three-dimensional (3D) phantom using solid model is constructed and the positioning on a personal computer (PC) using the 3D phantom is performed. Next, the plane image corresponding to the displayed phantom position from the CT image data is calculated. By using our developed tool, it is expected that students could perform the positioning training without having to expose X-rays and develop the films. © 2011 IEEE.

Study design:Non-randomized study.Objectives:Previous studies indicated that at least 2-h leg exercise at more than 60% maximum oxygen consumption (VO 2 max) increased plasma interleukin (IL)-6 in able-bodied (AB) subjects. The purpose of the present study was to compare IL-6 response to arm exercise in AB subjects and persons with spinal cord injury (SCI).Setting: Wakayama Medical University in Japan.Methods:Six subjects with SCI between T6 and T10 and seven AB subjects performed 2-h arm crank ergometer exercise at 60%VO 2 max. Plasma catecholamines, IL-6, tumor necrosis factor (TNF)-α and high-sensitivity C-reactive protein (hsCRP) were measured before exercise, 60-min exercise, immediately and 2 h after the completion of exercise.Results:Arm exercise increased myoglobin and plasma IL-6 levels in SCI and AB (P<0.01), but there were no differences in them between the two groups throughout the study. Plasma levels creatine kinase, lactate dehydrogenase, TNF-α and hsCRP did not change throughout the study in both groups.Conclusion:These findings suggest neither significant muscle damage nor inflammatory response during exercise. The increase in plasma IL-6 in SCI was not unexpected, confirming that moderate intensity and relatively long-arm exercise is safe and beneficial for SCI subjects with regard to IL-6 excretion, as in AB subjects. © 2011 International Spinal Cord Society.

In radiography the human body must be accurately and quickly positioned under X-ray equipment in order to obtain an image of the examined organ. The good positioning skill of the radiological technologist is essential for obtaining accurate diagnostic information of an examined organ and for reducing X-ray exposure in radiography. In this study, we developed a computed tomography (CT) image-based training system which could assist the students to train the positioning practice. By using a personal computer (PC) the positioning could be simulated. First, from the CT image data of the phantom scanned beforehand, we constructed the three-dimensional (3D) phantom based on a solid model and we performed the positioning of the 3D phantom on the PC. Next, we calculated the plane image from the CT image data corresponding to the positioned phantom and displayed the calculated plane image. By using our proposed training system, it was expected that students could perform the positioning training at the same time without having to expose X-rays and develop the films. ©2010 IEEE.

Mammographic X-ray equipment uses a radiographic grid to remove the scatter radiation and improve image contrast. The grid causes striped lines to appear on the film and may degrade diagnostic information. This study deals with the mechanism of the gridline appearance, the gridline image on the mammographic film, and a method for eliminating the gridlines. In this study, the background noise caused by the radiographic grid is investigated by using a one-dimensional Fourier transform and the characteristics of the gridlines on the X-ray film are clarified. In addition, a new method that reduces the background noise caused by the radiographic grid on mammographic film is proposed by using non-linear image filtering. To eliminate gridlines effectively, the region of the filter is considered and V-filtering and median filtering are performed as methods of image filtering. In an experiment using a breast phantom, a signal-to-noise ratio (SNR) in the microcalcification region is calculated. The SNR of the image processed by median filtering after the V-filtering is increased. The value of the power spectrum at a frequency that represents the periodic noise made by the gridlines is decreased. The validity of image filtering is confirmed. This proposed image-filtering method is found to be useful for eliminating gridlines in the X-ray image. © 2011 The Institution of Engineering and Technology.

Study design:Non-randomized study.Objective:We reported that individuals with cervical spinal cord injury (CSCI) showed no increase in natural killer cell activity (NKCA) in response to 20-min arm exercise. It could be argued that this lack of response was owing to the short duration and intensity of the exercise.Setting:The 29th Oita International wheelchair marathon race.Methods:The present study compared the effects of wheelchair half-marathon race on natural killer (NK) cell count, NKCA and other hematological and hormonal parameters in six subjects with CSCI and seven control subjects with spinal cord injury between T4 and L1 (SCI), before, immediately after and 2 h after recovery.Results:NK cell counts increased at both time points after the race in SCI, but not in CSCI, compared with before the race. NKCA increased immediately in both groups of subjects after the race, and then returned to the pre-race level at 2 h after the race. Plasma cortisol did not change in both groups throughout the study. Plasma adrenaline increased sharply in SCI after the race, then returned to the pre-race level at 2 h after the race, whereas no change was observed in CSCI throughout the study.Conclusion:The present study demonstrated that wheelchair half-marathon race increases NKCA despite the lack of increase in plasma adrenaline in CSCI, suggesting the activation of NKCA by mechanisms other than circulating adrenaline level. © 2012 International Spinal Cord Society.

A retrospective multicenter study.To investigate the characteristics of bowel dysfunction in elderly people with traumatic central cord syndrome (TCCS).A total of 28 Rosai hospitals in Japan.The Rosai Hospital registry included 3006 persons with spinal cord injury during 1997-2007. The study subjects were 186 patients with TCCS (160 men, 26 women; mean age, 61.711.6 years, s.d.). Patients were divided according to age into the young group (<50 years, n=30), the middle-age group (50-69 years, n=112) and the elderly group (70 years, n=44). We assessed the differences in bowel management techniques (spontaneous, rectal medications and manual emptying) and activity of daily living (ADL) with respect to bowel care at discharge among the three groups.Continent spontaneous defecation was the most common bowel management method (50%, 93/186). The percentage of elderly subjects on continent spontaneous defecation (36.4%) was significantly less than that of the young group (66.7%; P<0.05). Furthermore, the percentage of elderly patients who required no bowel care (18.2%) was significantly less than those of the young (53.3%) and middle-age groups (41.1%; P<0.01). However, few differences in bowel care-related ADL were recognized among the three groups in patients who required manual emptying.The results identified significantly fewer patients aged 70 years with continent spontaneous defecation or independent for bowel care compared with younger patients. The results also highlighted the clinical importance of bowel dysfunction associated with TCCS especially in elderly people.
