The successful treatment of microscopic polyangiitis associated with non-tuberculous mycobacterial-pulmonary disease.

While the incidence and prevalence of non-tuberculous mycobacterial-pulmonary disease (NTM-PD) are increasing and microscopic polyangiitis (MPA) is common in East Asian countries, case reports of MPA associated with NTM-PD are limited. A 72-year-old male receiving treatment for NTM-PD with antibiotics was referred to our hospital with fever and arthralgia that developed a few months previously. A blood test revealed the presence of the myeloperoxidase antineutrophil cytoplasmic antibody (MPO-ANCA) and renal impairment. Based on a pathological examination of renal tissue, which showed crescentic glomerulonephritis, the patient was diagnosed with MPA. Due to acute kidney injury and strongly positive MPO-ANCA, pulse steroid therapy was initiated followed by intravenous rituximab (RTX). The patient also received plasmapheresis (14 sessions). Renal dysfunction was reversed. MPA associated with NTM-PD is extremely rare and, thus, there is currently no established treatment. Our patient was diagnosed with MPA based on the findings of renal biopsy while receiving treatment for NTM-PD. RTX and plasmapheresis combined with systemic glucocorticoid therapy were initiated before these clinical conditions had fully recovered. Although MPA secondary to NTM-PD may be more refractory to treatment than primary MPA in the presence of a very low interferon-gamma (IFN-γ) level, this case was successfully treated with steroids, RTX, and plasmapheresis.

Effect of exercise therapy on cytokine secretion in the saliva of bedridden patients.

[Purpose] The number of bedridden patients requiring nursing care in Japan has increased sharply in recent years because of its aging population and advances in medical care and has become a major social issue. Because bedridden patients are susceptible to nursing and healthcare-associated pneumonia, it is very important to improve their immunocompetence. Therefore, the effect of exercise therapy on stimulation of cytokine secretion in the saliva of bedridden patients was investigated. [Subjects and Methods] The subjects of this study were bedridden patients admitted to nursing care facilities. They were instructed to perform active assistive movement in the supine and sitting positions, with vital signs used as an index of the exercise load. Thirty-five patients fulfilled the inclusion criteria, which included cerebrovascular disease as the main cause of being bedridden and at least 6 months since onset. Interleukins were measured by enzyme-linked immunosorbent assay as immune mediators. [Results] Vital signs improved significantly after therapeutic exercise intervention, and the IL-6, IL-8, IL-15, and IL-17 levels also increased significantly after the intervention. [Conclusion] The results demonstrated that measurement of saliva samples may offer a safe minimally invasive method of measuring immune response in bedridden patients. This study suggests that exercise therapy may hold promise as an effective means of improving immunity in bedridden patients and may contribute to preventing aspiration pneumonia and promoting spontaneous recovery.

Effects of clinical practice focusing on level-3 OSCE items.

[Purpose] This study examined the effects of clinical training focusing on level-3 OSCE (analytical and therapeutic skills) items, and compared the achievement levels of physical (PT) and occupational (OT) therapist students. [Subjects] A total of 282 (165 PT and 117 OT) students enrolled at our university between 2008 and 2010 were studied. [Methods] OSCE scores were compared between before and after clinical training focusing on level-3 OSCE items, and between PT and OT students. [Results] Scores for 5 out of the 6 level-3a items were significantly higher after than before clinical training. Increases in scores of 2 or 3 level-3b and -3c items were also observed after clinical training. There were no marked differences between PT and OT students in scores for level-3a, -3b, and -3c items before clinical training. In contrast, after clinical training, OT students' scores for 3a and 3c items related to dressing were higher than those of PT students, and the latter's scores for 3b items related to transfer were higher than those of the former. [Conclusion] The results suggest level-3 OSCE items are effectively taught during clinical training.

OSCE-based Clinical Skill Education for Physical and Occupational Therapists.

[Purpose] The aim of this study was to examine the applicability of the Objective Structured Clinical Examination (OSCE) to postgraduate education systems for novice and mid-career therapists in workplaces. [Subjects] Physical and occupational therapists with 1 to 5 years of clinical experience took the OSCE to assess their learning, with a physical or occupational therapy faculty member and a clinical supervisor as examiners. Another clinical supervisor acted as a simulated patient. [Methods] A Wilcoxon signed-rank test was performed to compare skills between before and after OSCE-based learning, and a Mann-Whitney U test was used to compare them between therapists with 1 to 2 years (novice) and 3 to 5 years (mid-career) of clinical experience. [Results] While no experience-related differences were observed in behavioral aspects, mid-career therapists exhibited markedly higher scores compared with novices in technical aspects, such as skills to guide patients for standing up, transfer, and dressing. [Conclusion] The OSCE may be sufficiently applicable to postgraduate education systems in workplaces.

Reliability of the OSCE for Physical and Occupational Therapists.

[Purpose] To examine agreement rates between faculty members and clinical supervisors as OSCE examiners. [Subjects] The study subjects were involved physical and occupational therapists working in clinical environments for 1 to 5 years after graduating from training schools as OSCE examinees, and a physical or occupational therapy faculty member and a clinical supervisor as examiners. Another clinical supervisor acted as a simulated patient. [Methods] The agreement rate between the examiners for each OSCE item was calculated based on Cohen's kappa coefficient to confirm inter-rater reliability. [Results] The agreement rates for the behavioral aspects of the items were higher in the second than in the first examination. Similar increases were also observed in the agreement rates for the technical aspects until the initiation of each activity; however, the rates decreased during the middle to terminal stages of continuous movements. [Conclusion] The results may reflect the recent implementation of measures for the integration of therapist education in training schools and clinical training facilities.

Standardization of Clinical Skill Evaluation in Physical/Occupational Therapist Education -Effects of Introduction of an Education System Using OSCE-.

[Purpose] A major issue in physical/occupational therapist education is the improvement of students' clinical techniques. In this study, we introduced an education system using an Objective Structured Clinical Examination (OSCE), and made an attempt at standardization of its evaluation. [Subjects] The subjects were 227 students in the classes of 2008 to 2010 who enrolled at our university between 2004 and 2006, before the introduction of the education system using OSCE, and 221 students in the classes of 2011 to 2013 who enrolled between 2007 and 2009, after the introduction. [Methods] Performances in attitude and skills (performance in clinical training and OSCE) were compared between before and after the introduction of OSCE. OSCE results were compared between before and after clinical trainings at each OSCE Level; and the correlation of between performances in clinical training and OSCE was examined. [Results] Performances in OSCE and clinical training (attitude, skills) were improved by the introduction of the education system using OSCE, but no significant correlation was observed in the relationship between performances in OSCE and clinical training. [Conclusion] Further studies should be conducted aiming at the standardization of clinical skill evaluation in postgraduate education to establish an education system using OSCE.

Long-term plasma levels and dose modulation of alacepril in patients with chronic renal failure.

Because most angiotensin-converting enzyme inhibitors are excreted into urine, any decrease in renal function increases the plasma levels of these drugs. This study was designed to investigate the appropriate doses of alacepril in patients with chronic renal failure. The total plasma concentration of captopril, an active metabolite of alacepril, was measured in 47 patients with chronic renal failure or normal renal function. Fifteen patients on chronic hemodialysis were also enrolled in this study. In patients treated with 12.5, 25 and 50 mg alacepril, the plasma concentration of captopril was linearly correlated with serum creatinine and creatinine clearance (Ccr). There was an approximately 40% decrease of the plasma captopril concentration after 4 h of hemodialysis. Among patients treated with 25 or 50 mg alacepril for 4.5 years, the plasma concentration of captopril gradually increased along with an increase in serum creatinine (from 2.0 to 5.8, and from 1.9 to 7.1 mg/dL, respectively). Although the plasma concentration of captopril was higher in the 50 mg group, the increase in serum creatinine during this period was not different between the two groups. The plasma aldosterone concentration did not increase during this period. These data suggest that alacepril should be reduced from 50 to 25 and 12.5 mg/day in patients with a serum creatinine level of greater than 2-3 and 4-6 mg/dL, respectively, in order to maintain a plasma level equivalent to that in subjects with normal renal function receiving 50 mg/day alacepril. For patients on chronic hemodialysis, 12.5 mg alacepril is the appropriate dose.

The features of dry eye disease in a Japanese elderly population.

PURPOSE: The purpose of this study is to assess the features of dry eye disease in a Japanese elderly population. METHODS: One hundred thirteen left eyes of 113 pensioners (50 males, 63 females; mean age, 67.5 +/- 5.7 years) aged over 60 years were recruited in this study. The subjects underwent careful slit-lamp examinations of the conjunctiva, ocular surface, and the eye lids. Tear film breakup time (BUT) examinations, Schirmer test-I, and fluorescein staining of the ocular surface and transillumination of the eyelids were also performed. Dry eye symptomatology was assessed with a symptom questionnaire. Japanese Dry Eye Diagnostic Criteria were used in this study. RESULTS: Ocular tiredness, irritation, dryness, and foreign body sensation were the most frequently reported symptoms by the patients. A total of 73.5% of the eyes had definite dry eyes. A total of 39.8% of the eyes had a Schirmer test reading <5 mm. Mean Schirmer test value was 9.4 +/- 7.8 mm. The mean BUT score was 4.0 +/- 2.8 seconds. A total of 76.9% of the eyes had positive fluorescein staining of the cornea. Meibomian gland dysfunction and conjunctivochalasis were found as frequent factors in relation to dry eye disease with meibomian grand dropout showing positive correlation with tear instability. CONCLUSION: Qualitative and quantitative disorders of the tear film were far more common than recognized in this population of elderly subjects, meibomian gland dysfunction being the most common associate of the tear film disorder and dry eye status. Conjunctivochalasis (conjunctival laxity), although commonly associated with dry eye disease in the elderly, was observed not to be related to age or gender in this study.

Successful treatment of a patient with severe calcific uremic arteriolopathy (calciphylaxis) by etidronate disodium.

A 59-year-old woman with a 10-year history of hemodialysis was admitted to our hospital for painful skin ulcers on her right thigh, right calf, and left upper arm. A whole-body plain computed tomographic scan showed diffuse calcification of the uterus and marked calcification of the mitral valve. Skin biopsy specimens from the left thigh showed calcium deposition in numerous small blood vessels in the dermis and fat, leading to a diagnosis of calcific uremic arteriolopathy (CUA). Despite antibiotic therapy and aggressive wound care for 2 months, the skin ulcers enlarged and the patient's general condition worsened. Surprisingly, oral administration of etidronate disodium (200 mg/d) strikingly improved the focal infection and decreased the size of the skin ulcers within several days. She was discharged from the hospital 2 months later, when epithelialization of the ulcers was almost complete. We report a case of CUA that was improved dramatically by treatment with etidronate. Etidronate therapy should be considered for refractory CUA.

Short-term effects of external and internal biliary drainage on liver and cellular immunity in experimental obstructive jaundice.

BACKGROUND/PURPOSE: The effects of preoperative biliary drainage for obstructive jaundiced patients are controversial. Although experimental studies have proven the benefit of internal biliary drainage (ID) over external biliary drainage (ED), ID has several clinical problems, such as clogging or tube replacement. The aim of this study was to determine whether there were any differences in T-cell function, liver function, and histology, between rats in ID and ED groups in short-term experiments. METHODS: Following bile duct ligation (BDL) for 14 days, rats in the ED and ID groups had 7 days of ED and 7 days of ID, respectively. Normal rats were used as negative controls (control group). For positive controls, we used a group with BDL and no drainage (BDL group). Serum bilirubin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and alkaline phosphatase (ALP) were measured, splenic T-cell proliferation was assayed to check cellular immunity, and liver histology was examined. RESULTS: Recovery of bilirubin and ALT was similar in the ED and ID groups. Recovery of AST was worse in the ID group than in the ED group, but the difference was not statistically significant. Levels of ALP in the BDL and ID groups were significantly higher than those in the control and ED groups. Rats in the BDL group showed a significant decrease in T-cell function compared to the control group. The ED group showed better recovery of T-cell function than the ID group in the 7 days after relief of obstructive jaundice. The livers in the ID group demonstrated histologically moderate interface hepatitis with periportal inflammation and lymphocyte infiltration, which strongly suggested incomplete tube obstruction, but those in the ED group showed minimal change. CONCLUSIONS: ED is superior to ID concerning the recovery of cellular immunity and liver inflammation in the short-term after relief from biliary obstruction in this model. As the patency of the tube is well maintained in ED compared to ID, patency of the tube is essential to obtain good recovery of cellular immunity, irrespective of the drainage method.

Pre- and post-operative adjuvant chemotherapy in colorectal cancer.

A multi-center randomized controlled study was conducted in order to investigate the usefulness of pre- and post-operative adjuvant chemotherapy in colorectal cancer. The patients were stratified into those with colon cancer and those with rectal cancer and divided into 2 groups, Group A and Group B. The patients in Group A received tegafur suppositories (750 mg/day) from 1 to 2 weeks prior to surgery, to 2 weeks following surgery and then oral administration of tegafur and uracil (UFT) (260 mg/m(2)) for 1 year. The patients in Group B, on the other hand, received only UFT (260 mg/m(2)) for 1 year beginning week 2 after surgery. Although there was no significant difference between Groups A and B in the 5-year survival rate, the 5-year disease-free survival rate was significantly higher in Group A, especially for rectal cancer (p<0.05). In addition, remote metastases tended to be suppressed for both colon and rectal cancer in Group A (p=0.08 and p=0.072). There was no serious adverse reaction to tegafur. Pre- and post-operative adjuvant chemotherapy with tegafur had fewer adverse reactions and was convenient to administer. Thus, it was considered useful for suppression of postoperative distant metastasis in colorectal cancer.
