A 42-year-old man with primary tongue cancer was admitted to our palliative care center for the control of pain due to multiple bone metastases. On 30th day after admission, he was suffering from pneumonia. And on 37th day, chest radiograph demonstrated pericardial emphysema, which developed to the pericardial abscess. Chest Computed Tomography showed lymph nodes metastases around the left main bronchus, and revealed that there was a fistula between the left main bronchus and the pericardium. The patient was faced to the difficulty in taking spine position because of excessive excretion of the sputum. Pericardiocentesis was then performed percutaneously and a tube for the drainage was placed. After the placement of drain tube, he restored good night sleep in the spine position and the complaints were reduced. Palliat Care Res 2008; 3(2): 321-325

Recent studies showed that high biocompatibility and reduction of uremic toxin contributed to the improvement of freatment outcome in hemodialysis patients.Therefore, a high-flux membrane dialyzer, especially polysulfone (PS) membrane, was generally used in dialysis. However, it was suggested that the higher efficiency of reduction in uremic toxins might cause an increase in the albumin leakage through the dialyzer membrane during dialysis, resulting in a decrease in serum albumin concentration. In this study, we used two different dialyzer membranes with high biocompatibility, namely, ethylenevinylalcohol (EVAL) membrane and improved PS membrane with a very lower leakage of serum albumin. After using these two types of mambrane of six straight months, we examined the effect of each dialyzer membrane characteristic on the serum total protein and albumin concentration. The reduction rates of each uremic solute and serum total protein concentration were significantly higher. The serum albumin concentration and its rate of change with the passing of time tended to increase in the case of the PS membrane. But in the case of EVAL membrane, these values tended to decrease. These results suggested that the differences in the changes in the serum total protein and albumin concentration might result from the differences in the efficiency of the reduction of uremic toxins. Therefore, it is necessary to consider the usage of the dialyzer membrane with a higher reduction of uremic solutes and a lower leakage of serum albumin to add to the higher biocompatibility specially in hemodialysis patients with hypoproteinemia.

The purpose of this study was to examine the effects of crocetin on the pupillary response during accommodation induced by visual display terminal (VDT) work. This clinical study was conducted as a randomized, double-blind, placebo-controlled, crossover trial in healthy adult volunteers with subjective symptoms of eye fatigue. In this study, the pupillary response during accommodation was evaluated using pupil constriction ratio (PCR). PCR was measured before and after VDT work, after rest at baseline, and at each intervention period. Following analysis of variations in PCR, the variation in PCR after rest significantly increased in the crocetin group. According to the visual analog scale questionnaire, subjective symptoms of eye fatigue significantly improved. These results show that ingestion of crocetin for 4 weeks is effective in mitigating the pupillary response during accommodation associated with VDT work.

Due to the widespread acceptance of gastric and esophageal endoscopic submucosal dissections (ESDs), the number of medical facilities that perform colorectal ESDs has grown and the effectiveness of colorectal ESD has been increasingly reported in recent years. The clinical indications for colorectal ESD at the National Cancer Center Hospital, Tokyo, Japan include laterally spreading tumor (LST) nongranular type lesions >20 mm and LST granular type lesions >30 mm. In addition, 0-IIc lesions >20 mm, intramucosal tumors with nonlifting signs and large sessile lesions, all of which are difficult to resect en bloc by conventional endoscopic mucosal resection (EMR), represent potential candidates for colorectal ESD. Rectal carcinoid tumors less than 1 cm in diameter can be treated simply, safely, and effectively by endoscopic submucosal resection using a ligation device and are therefore not indications for ESD. The en bloc resection rate was 90%, and the curative resection rate was 87% for 806 ESDs. The median procedure time was 60 minutes, and the mean size for resected specimens was 40 mm (range, 15 to 150 mm). Perforations occurred in 23 (2.8%) cases, and postoperative bleeding occurred in 15 (1.9%) cases, but only two perforation cases required emergency surgery (0.25%). ESD was an effective procedure for treating colorectal tumors that are difficult to resect en bloc by conventional EMR. ESD resulted in a higher en bloc resection rate as well as decreased invasiveness in comparison to surgery. Based on the excellent clinical results of colorectal ESDs in Japan, the Japanese healthcare insurance system has approved colorectal ESD for coverage.

STUDY DESIGN: In vivo biomechanical study using a three-dimensional (3D) musculoskeletal model for elderly individuals with or without pelvic retroversion. PURPOSE: To evaluate the effect of pelvic retroversion on the sagittal alignment of the spine, pelvis, and lower limb in elderly females while standing and walking. OVERVIEW OF LITERATURE: Patients with hip–spine syndrome have concurrent hip-joint and spine diseases. However, the dynamic sagittal alignment between the hip joint and spine has rarely been investigated. We used a 3D musculoskeletal model to evaluate global spinopelvic parameters, including spinal inclination and pelvic tilt (PT). METHODS: A total of 32 ambulant females (mean age=78 years) without assistance were enrolled in the study. On the basis of the radiographic measurement for PT, participants were divided into the pelvic retroversion group (R-group; PT≥20°) and the normal group (N-group; PT<20°). A 3D musculoskeletal motion analysis system was used to analyze the calculated value for the alignment of spine, pelvis, and lower limb, including calculated (C)-PT, sagittal vertical axis (C-SVA), pelvic incidence, lumbar lordosis, T1 pelvic angle (C-TPA), as well as knee and hip flexion angles while standing and walking. RESULTS: While standing, C-PT and C-TPA in the R-group were significantly larger than those in the N-group. Hip angle was significantly smaller in the R-group than in the N-group, unlike knee angle, which did not show difference. While walking, C-SVA and C-TPA were significantly increased, whereas C-PT decreased compared with those while standing. The maximum hip-flexion angle was significantly smaller in the R-group than in the N-group. There was a significant correlation between the radiographic and calculated parameters. CONCLUSIONS: The 3D musculoskeletal model was useful in evaluating the sagittal alignment of the spine, pelvis, and leg. Spinopelvic sagittal alignment showed deterioration while walking. C-PT was significantly decreased while walking in the R-group, indicating possible compensatory mechanisms attempting to increase coverage of the femoral head. The reduction in the hip flexion angle in the R-group was also considered as a compensatory mechanism.

The purpose of this study was to confirm the causal structure model of muscle, motor and living functions utilizing structural equation modeling (SEM) . As subjects, 103 community-dwelling older men and women, aged 65.7±6.9years of age, participated in the study to measure muscle cross-sectional area, maximum voluntary contractions, muscle power, 4 physical performance tests, and 16 questionnaires regarding ability of activities of daily living. The causal structure model of muscle, motor and living functions was hypothesized to be a hierarchical causal structure. The causal structure model of muscle function was hypothesized to be a hierarchical causal structure consisting of 3 sub-domains of muscle mass, muscle strength, and muscle power. Data analysis procedures were as follows : a) testing of construct validity of muscle function variables using confirmatory factor analysis (CFA) in SEM ; b) testing of causal structure using SEM ; c) testing of factor invariance using multi-group analysis for gender. The highest goodness of fit indices was obtained in the causal structure model of muscle, motor and living functions (NFI= .928, CFI= .978, RMSEA =.061) . The causal coefficient of muscle function to motor function was .98 (p<.05), followed by.34 for motor function to living function. From the results of multi-group analysis, the measurement invariance model indicated the highest goodness of fit indices (TLI=.968, CFI .977) . It was concluded that the hierarchical causal relation was among muscle, motor and living functions, and in which muscle function was consisted of 3 sub-domains.

The purpose of this study was to confirm the reliability and validity of a physical fitness questionnaire (PFQ) with self-rating for elderly people applying structural equation modeling (SEM) . As subjects, 105 community-dwelling older men and women aged 67.1±6.1 years participated in the study to measure 13 PFQ items and 13 performance tests. The data analysis procedures were as follows : a) testing reliability of PFQ ; b) testing of construct validity of PFQ using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) ; c) testing of criterion-related validity of PFQ to the performance tests using SEM ; d) testing of correlations of the PFQ to walking ability using SEM. Cronbaeh's alpha coefficient for consistency reliability of the PFQ was .83. Four common factors of muscle strength-power, endurance, coordination, and flexibility were extracted in EFA. The high and enough goodness of fit indices were obtained in the confirmatory factor structure model, and in each sub-domain of criterion-related validity to performance tests and correlation to walking ability models. The criterion-related validity coefficient of muscle strength and power was .77, followed by .66 for endurance, .59 for coordination and .82 for flexibility. The correlation coefficient of muscle strength and power to walking ability was -.51, followed by -.58 for coordination, - .43 for endurance and - . 28 for flexibility. These results indicated that the PFQ consisting of 13 items and 4 sub-domains satisfied reliability and construct validity although criterion related validity to performance tests was insufficient. It was concluded that the PFQ is of useful for physical fitness checking of elderly people.
