Coronary artery disease (CAD) was evaluated by noninvasive examination in abdominal aortic aneurysm (AAA) patients. A simultaneous operation or a 2-staged operation was performed depending on the seriousness of the condition when both diseases were combined. A total of 36 patients underwent elective repair of AAA between 1996 and 2001. Coronary angiography (CAG) was performed only in patients with suspected CAD by dipyridamole myocardial scintigraphy. Significant CAD was found in 8 patients. Simultaneous operation was performed in 4 patients, and off-pump coronary artery bypass grafting (OPCAB) was performed in all cases of simultaneous operation. In 4 patients receiving 2-staged operations, 1 standard coronary artery bypass grafting (CABG), 1 OPCAB and 2 percutaneous transluminal coronary angioplasties (PTCA) were performed prior to AAA surgery. Twenty-eight patients underwent only AAA operation. Though there were no incidents of perioperative myocardial infarction or cardiac related deaths in this group, 2 patients died due to other causes (hemorrhage and duodenal perforation). In the 8 patients associated with CAD, 1 patient died of MNMS after simultaneous operation. The other 7 patients revived their social function soon of the discharge. Dipyridamole cardiac scintigraphy was considered to be an effective examination for evaluation of CAD in AAA patients. There was no need to perform CAG in all AAA patients. The policy of choosing simultaneous operation or 2-staged operation according to the seriousness of the 2 diseases seemed to be appropriate.

OBJECTIVE: This study examined the utility of adenine for preventing clozapine-induced neutropenia. METHODS: This retrospective study examined the effect of adenine on clozapine-induced neutropenia in patients with treatment-resistant schizophrenia and was conducted at Okehazama Hospital in Japan from July 2010 to June 2013. Adenine was available for use from June 2011 onwards. Twenty-one patients started receiving clozapine treatment from July 2010 to April 2011 (the pre-adenine adoption group), and 47 patients started receiving it from May 2011 to June 2013 (the post-adenine adoption group). The effects of adenine were assessed based on changes in the patients' leukocyte counts and the frequency of treatment discontinuation due to clozapine-induced neutropenia. RESULTS: Sixty-eight patients were treated with clozapine from July 2010 to June 2013. Of the 21 patients in the pre-adenine adoption group, 4 discontinued treatment due to clozapine-induced neutropenia, whereas only 2 of the 47 patients in the post-adenine adoption group discontinued treatment. The frequency of treatment discontinuation due to clozapine-induced neutropenia was significantly lower in post-adenine adoption group than in the pre-adenine adoption group (p=0.047). CONCLUSION: Adenine decreased the frequency of treatment discontinuation due to clozapine-induced neutropenia. Our data suggest that combined treatment with clozapine and adenine is a safe and effective strategy against treatment-resistant schizophrenia.

Clozapine has been demonstrated to be useful for treating refractory schizophrenia. However, hypersalivation occurs in 31.0-97.4% of the patients treated with clozapine. Accordingly, some patients who are disturbed by their hypersalivation refuse to continue with clozapine treatment. This study investigated the efficacy of the anticholinergic agent scopolamine butylbromide against clozapine-induced hypersalivation. Five schizophrenia patients were coadministered scopolamine butylbromide (30-60 mg/day) for 4 weeks. At the baseline and after 4 weeks' treatment, we subjectively evaluated hypersalivation using a visual analog scale and objectively assessed it using the Drooling Severity Scale and Drooling Frequency Scale. As a result, improvements in the patients' Drooling Severity Scale and Drooling Frequency Scale scores, but no improvements in their visual analog scale scores, were observed after scopolamine butylbromide treatment. These results indicate that at least some schizophrenic patients with clozapine-induced hypersalivation would benefit from scopolamine butylbromide treatment. We conclude that clozapine-induced hypersalivation is one factor of stress to patients. Subjective hypersalivation was not improved, but objective hypersalivation was, by scopolamine butylbromide treatment. However, scopolamine butylbromide and clozapine possess anticholinergic effects so clinicians should closely monitor patients who take scopolamine butylbromide.

BACKGROUNDOsteoarthritis (OA) is a chronic and incurable disease, lacking effective treatment. Gene therapy offers a radical different approach to the treatment of arthritis. Even though the etiology of OA remains unclear, there is now considerable evidence to suggest that interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-alpha) are the main mediators in the pathogenesis of OA. The goal of this study was to determine the efficacy of local expression of interleukin-1 receptor antagonist (IL-1Ra) and soluble tumor necrosis factor-alpha receptor type I (sTNF-RI) by direct adenoviral-mediated intra-articular gene delivery in the rabbit model of osteoarthritis.

METHODSAdenoviral vectors containing IL-1Ra or sTNF-RI genes were constructed. OA was induced in both hind knees of 12 New Zealand white rabbits by the excision of the medial collateral ligament plus medial meniscectomy. Five days after surgery, approximately 1 x 10(8) plaque-forming units (pfu) of adenovirus were injected into the joint space of the knee through the patellar tendon. A total of 12 operated rabbits were divided into four groups. Three experimental rabbit groups received 1 x 10(8) pfu of adenovirus encoding either IL-1Ra (3 rabbits), sTNF-RI (3 rabbits) or IL-1Ra and sTNF-RI in combination (3 rabbits), into both knee joints respectively. An inflamed control group of 3 rabbits received approximately 1 x 10(8) pfu of Ad-GFP into both joints. Three days after injection of the adenovirus, both knees of each rabbit were lavaged with 1 ml of saline solution through the patellar tendon. At day 7, the rabbits were sacrificed, and the knees were lavaged, dissected and analyzed for effects of transgene expression. Levels of IL-1Ra and sTNF-RI expression in recovered lavage fluids were measured using a cytokine ELISA kit. Cartilage from the lesion areas of medial femoral condyle and synovium were fixed, embedded, sectioned and stained with hematoxylin and eosin (cartilage and synovium) and toluidine blue (cartilage). The samples were examined by light microscopy and quantitatively evaluated.

RESULTSIntra-articular delivery of IL-1Ra resulted in a significant inhibition of cartilage degradation, but did not affect synovial changes. In contrast, rabbit knee joints receiving sTNF-RI alone showed no detectable reduction in cartilage degradation. However, double gene transfer of IL-1Ra and sTNF-RI resulted in a higher suppression of the cartilage degradation and an observable reduction in synovitis. These data add to and confirm that IL-1Ra has good chondroprotective properties, but TNF-alpha blockade has little effect on joint destruction.

CONCLUSIONThe enhanced therapeutic effects of both antagonists in combination suggest inhibition of multiple inflammatory cytokines may be more efficacious than blockade of either cytokine alone in treating OA.

OBJECTIVETo investigate the relationships between sick building syndrome and mold in newly-built dwellings.

METHODSSymptoms of 61 residents in 18 dwellings were surveyed by standardized questionnaires. Mold sampling was done by gravity sampling using an open Petri dish. Potato dextrose agar (PDA) and dichloran-18% glycerol agar (DG-18) were used as the culture medium.

RESULTSThere were 6 dwellings in which at least one inhabitant complained of one or more symptoms and 12 dwellings in which none of the inhabitants complained of symptoms. There was a tendency for the dwellings with inhabitants reporting symptoms to have larger colony forming units (CFU) on PDA than those without inhabitants reporting symptoms (p=0.1), but there was no difference in DG-18 result. There was a tendency for the dwellings with inhabitants reporting symptoms to have larger CFU ofCladosporium on PDA than those without (p=0.08), but there was no difference in DG-18 result. Significantly moreUlocladium sp. was detected in the dwellings with inhabitants reporting symptoms than in those without (p=0.03).Cladosporium cladosporioides was detected in all the dwellings with inhabitants reporting symptoms and 75% of the dwellings without.Cladosporium macrocarpum andCladosporium herbarum were detected in 33% of the dwellings with inhabitants reporting e symptoms and none of the dwellings without (p=0.1).

CONCLUSIONCladosporium was dominant in the Japanese newly-built dwellings studied, andCladosporium andUlocladium were probably associated with the residents' symptoms in these newly-built dwellings.

The purpose of this study was to clarify the relationship between quality of motion and motor ability in early childhood, as well as the moderating effects of grade and gender. A total of 133 preschoolers (3- to 5-year-old class) were evaluated for quality of motion and motor ability using the “Athletic Aptitude Test II” developed by the Japan Sports Association to assess the fundamental movements of running, jumping, and throwing. Two observers evaluated quality of motion based on movies taken by tablet. The relationship between quality of motion and motor ability was determined using multiple regression analysis. In addition, we clarified the influence of grade and gender on the relationship between quality of motor and motor ability using moderation analysis. A significant relationship was found between quality of motion and motor ability for all movements. Grade moderated the relationship between the quality of running motion and the results of the 25-m run. Gender moderated the relationship between the quality of the throwing motion and the results of softball throwing. These results suggest an association between quality of motion and motor ability in early childhood, and show that improving quality of motion improves motor ability.

Because the corona disaster made group medical training difficult, we conducted resuscitation training for new students and basic medical skills training for fourth-year students without face-to-face instruction using video learning, assessment, and ICT. In the resuscitation training, the students were allowed to take a mannequin home and film themselves performing the resuscitation while learning by video. Later, group and peer assessment were conducted via Zoom, and a significant increase in self-assessment was observed. In the basic medical skills training, the students filmed their own implementation at their own pace while learning by video, and the teachers later conducted video assessment and feedback. The lack of face-to-face instruction made it possible to implement the limb spine training, which had not been possible in previous years. It is necessary to adjust the timing of the video registration by the students and the video assessment by the teachers, and to make further improvements to the system.
