Introduction: We experienced a case of pneumatosis cystoides intestinalis with intra-abdominal free air following steroid therapy for an end-stage brain tumor. Case: The patient was a 67-year-old man. He had received surgery and chemotherapy for the brain tumor, but the disease progressed and his consciousness deteriorated. Eventually, he developed aspiration pneumonia and was hospitalized. His consciousness level remained poor even after the pneumonia improved. His survival prognosis was considered to be approximately 1 month, and he was transferred to a palliative care ward. After the transfer, administration of betamethasone 8 mg/day was started for the purpose of improving his level of consciousness. Temporary improvement was observed, and administration of this drug was continued with dose adjustments, as appropriate. Six weeks after the start of betamethasone administration, when his consciousness level again deteriorated, aspiration began to recur. Chest X-rays, obtained to assess pneumonia, showed intra-abdominal free air. Pneumatosis cystoides intestinalis was confirmed by computed tomography. He had few abdominal symptoms, and was managed conservatively. He died of respiratory failure. Conclusion: Pneumatosis cystoides intestinalis is mostly secondary, and steroid therapy is considered to be one of the causes. But follow-up observation is often conservative, and judgment of discontinuation of steroid needs to be made in consideration of its effect and prognosis is there.

For diagnosis of prostate cancer, MRI was performed in 91 patients prior to prostate biopsy, and prostate cancer was detected in 37 patients. The ability of MRI diagnosis compared with biopsy was accuracy 0.84, sensitivity 0.95, and specificity 0.76.In 26 patients (14 patients with prostate cancer) from whom MR images were obtained by diffusion weighted imaging, ADC value and PSA value showed a reverse correlation significantly.The ADC value was 0.97±0.23-3mm2/sec in the cancer area, 1.51±0.20-3mm2/sec in the normal peripheral zone, and 1.47±0.12-3mm2/sec in the normal central zone. The ADC value in the cancer area was smaller than that in the normal peripheral area or in the normal central zone significantly (p<0.001).The relation between ADC value and Gleason score did not show any correlation. However, when the Gleason score was under 6, ADC value was 1.11±0.20-3mm2/sec, and when it was over 7, ADC value was 0.81±0.19-3mm2/sec which showed a lower value than the ADC value with Gleason score under 6 significantly (p<0.05).MRI was effective for visualization of prostate cancer. We concluded that pre-biopsy MRI in prostate cancer would allow not only systemic-biopsy but also accurate targeting-biopsy, and it would improve the diagnosric ability of biopsy.

Background: On receiving chemotherapy, extravasation of drugs is a severe problem. The extravasations occur more commonly in patients who are elderly, have a poor performance status, have diabetes mellitus complications or have repeatedly received chemotherapy. Also, cancer patients usually require repeated venous punctures for this treatment. Purpose and methods: For the purpose of evaluating the efficacy and safety of peripherally inserted central catheters (PICCs) for intravenous chemotherapy, we retrospectively reviewed all the cancer patients for whom PICC were inserted for chemotherapy from April 2008 to December 2010. Patients' background, duration of PICC insertion and complications were evaluated in this study. Results: Ten patients (male 4, female 6) were reviewed in this study. The median age was 59 years (17∼69). A total of 13 PICCs were inserted in 10 patients. The most common underlying disease was abdominal rhabdomyosarcoma (n=3, 30%) followed by lung cancer (n=2, 20%) and hematologic tumor (n=2, 20%). The average catheter span was 46 days. Catheter-related infections were seen in 2 cases (15.4%). No phlebitis or thrombosis usually associated with venous route was detected in PICC used for chemotherapy. Conclusions: PICC might reduce patients' discomfort such as repeated venous punctures or complications associated with chemotherapy. We suggest that PICC would be one of the effective tools in chemotherapy. Palliat Care Res 2011; 6(2): 233-236

Objectives: A survey was conducted to investigate the usability and safety of fentanyl sublingual tablets (FST) and to examine problems associated with their proper use.
Methods: Subjects were 18 cancer inpatients who received FST for breakthrough pain in their pharmacological cancer pain management. Changes in the pain score and the occurrence of adverse effects (nausea, vomiting and somnolence) were compared before and after FST administration.
Results: The pain score before FST administration was 6.4±2.4, and this was significantly improved to 3.4±2.8 at 30 min after administration (p<0.01). Somnolence occurred significantly more often 30 min and 2 h after FST administration than immediately before administration (p<0.05). There were no differences in the occurrence of nausea and vomiting before or after FST administration. Nine patients receiving FST therapy developed xerostomia, but there were no significant changes in the pain score or occurrence of adverse effects while they had xerostomia.
Conclusion: It is essential to observe the oral condition to judge whether FST therapy is indicated, and FST should be administered after providing sufficient oral care. The results indicate the possibility of increased occurrence of somnolence as an adverse effect.

Methods:
Thirty patients with LSS scheduled for spine surgery participated in this study. Lower limb pain was assessed using the Visual Analog Scale (VAS), and the patients were divided into two groups based on the mean scores (patients with scores above and below the mean were classified as the high-VAS and low-VAS groups, respectively). The kinematics of the spine, pelvis, and hip joints during gait were then measured using a 3D motion analysis system. Student paired t -tests were used to compare the angles of the spine, pelvis, and hip during gait between the two groups.
Results:
Compared to those in the low-VAS group, the spine was significantly extended and bent toward the more painful lower limb side, and the pelvis was significantly anteriorly tilted among individuals in the high-VAS group.
Conclusions
Patients with LSS experiencing severe pain in their lower limb tend to keep the spine in a more extended position, bend laterally toward the painful side, and have an anteriorly tilted pelvic posture. The dynamic spinal and pelvic alignment was closely related to the intensity of the lower limb pain.

Methods:
Thirty patients with ASD aged ≥50 years who were admitted to our hospital between July 2016 and September 2019 were included in this study. X-ray parameters (i.e., sagittal vertical axis, pelvic tilt, and pelvic incidence minus lumbar lordosis) were evaluated from the full-length standing radiographs of the subjects. Trunk and hip extensor strength was evaluated using a hand-held dynamometer. Dynamic postural changes (i.e., sagittal trunk shift during standing, sagittal trunk shift during gait, and delta sagittal trunk shift) were assessed using a three-dimensional motion analysis system. The relationships between dynamic postural change and various X-ray parameters, as well as trunk and hip extensor strength, were examined using multivariable analysis.
Results:
Multivariable analysis showed that hip extensor strength is the factor most strongly associated with dynamic postural change among the X-ray parameters and physical functions assessed in this study (β=−0.41, R2=0.12).
Conclusions
We demonstrated the association between dynamic postural change and hip extensor strength in patients with ASD. Our results may be useful to healthcare providers treating patients with ASD. Interventions for dynamic postural change in patients with ASD should focus on hip extensor strength.

The aim of the present study is to clarify the improvement of peripheral muscle oxygen consumption after successful renal transplantation. We investigated change of forearm (brachioradial muscle) muscular oxygen consumption in chronic renal failure children before and after renal transplantation. by using near-infrared spectroscopy.Oxygen consumption of brachioradial muscle was increased significantly after succesful renal transplantation. And half recovery time of brachioradial muscle oxygenation in arterial occlusion and exercise were decreased after renal transplantation.These results suggest that increased muscular blood flow and increased oxidative generation of ATP might contribute to the increased oxygen turn over after renal transplantation.

Although numerous studies have shown that each neuropsychological test is effective for diagnosing
mild cognitive impairment (MCI) or Alzheimer’s disease (AD), studies comparing diagnostic accuracies
of various neuropsychological tests are relatively rare and practical cutoff values are not available. The
present study aimed to investigate the validity of neuropsychological tests and develop cutoff values
for each in differentiating healthy control (HC), MCI and AD groups. A total of 84 HC, 187 with
MCI and 195 with AD were evaluated by the selected seven neuropsychological tests using receiver
operating characteristic (ROC) curve analysis. Logical Memory (LM) delayed recall (cutoff, 7) and
Rey Auditory Verbal Learning Test (RAVLT) delayed recall (cutoff, 6) were effective for differentiating
HC from MCI. To distinguish MCI and AD, Rey Osterrieth Complex Figure Test (ROCFT) 3 mindelayed
recall (cutoff, 6) and LM immediate recall (cutoff, 4) were excellent. Delayed recall of verbal
materials, as indexed by LM and RAVLT was sensitive for discriminating MCI from HC. Handling
visual memory traces, as indexed by ROCFT and immediate verbal information by LM were sensitive
for differentiating MCI and AD.

Objective: To validate and recalibrate Charlson and Elixhauser comorbidity indices (CCI and ECI, respectively) in a Japanese hospital-based administrative database.Methods: In this retrospective, cohort study, derivation and validation cohorts were developed to include all hospitalizations for patients aged ≥ 18 years at admission and discharged in 2015 or 2016, respectively, from an administrative database based on 287 hospitals. Seventeen CCI and 30 ECI conditions were identified using the International Classification of Diseases (ICD) -10 codes at admission or during the stay. Predictability for hospital death was evaluated using C statistics from multivariable logistic regression models including age, sex, and individual CCI/ECI conditions or the CCI/ECI score in the derivation cohort. After stepwise selection, weighted risk scores were re-assigned to each condition based on the odds ratios (CCI) or beta-coefficient (ECI), and these modified models were evaluated in the validation cohort.Results: The original CCI/ECI had good predictive abilities for hospital death: C statistics (95% confidence interval) for individual comorbidities and score models were 0.764 (0.762-0.765) and 0.731 (0.729-0.733) for CCI, and 0.783 (0.781-0.784) and 0.750 (0.748-0.752) for ECI, respectively. Modified CCI and ECI had 13 and 27 conditions, respectively, but maintained comparable predictive abilities: C statistics for modified individual comorbidities and score models were 0.761 (0.759-0.763) and 0.759 (0.757-0.760) for CCI, and 0.784 (0.782-0.785) and 0.783 (0.781-0.785) for ECI, respectively.Conclusions: The original and modified CCI/ECI models, with reduced numbers of conditions, had sufficient and comparable predictive abilities for hospital death and can be used in future studies using this administrative database.

This paper describes the concepts of assessment theory which are necessary to implement the most desirable assessments, with a particular focus on validity and utility. Validity, classically defined as a trinity of content, criterion-related, and construct, is now encompassed by construct validity. By distinguishing between validity and validation, the process of reinforcing validity through argument-based validation is proposed. Furthermore, we refer to the concept of utility, which takes into account practicality (acceptability and cost) and educational impact, in order to make the assessment practice sustainable. Finally, we will address how learner assessment relates to program evaluation.
