Diagnoses recorded in the chapter E of Minimum Data Set (MDS) were analyzed in patients requiring care admitted in a geriatric hospital in Sapporo, Japan. They were classified as: A-diseases causing care-requiring conditions, B-their symptoms, and C-coexisting diseases requiring no care. Orthopedic diseases were not analyzed because they were not adequately recorded in MDS system. Class A diagnoses varied, but only five diagnoses were responsible for 3% or more of the total patients who required care. They were 1) Alzheimer's disease (AD), 2) Parkinson's disease, 3) dementia other than AD without neurological symptoms, 4) dementia other than AD with sequelae of stroke, and 5) sequelae of stroke without dementia. These diagnoses pooled represented over 90% of all patients. "Diagnoses and symptoms" in MDS were useful to 1) describe medical problems briefly in a predetermined format, 2) evaluate urgent or unstable conditions separately from stable diagnoses and symptoms, and 3) use common information by various professions, but have difficulties because 1) preselected diagnoses were few and unsuited to practices in Japan, 2) it is impossible to record a previous disease in the past that initiated the process leading to the present disabilities, and 3) it is also impossible to record the severities of the diseases and symptoms. 相似文献
Objectives: We performed the Sauvé–Kapandji procedure for treating disorders of the distal radioulnar joint (DRUJ) in patients with rheumatoid arthritis (RA) or osteoarthritis (OA). This study aimed to compare and clarify the results of the SK procedure between RA and OA patients. We report the one-year follow-up results of patients who underwent the SK procedure to correct the DRUJ disorder caused by RA or OA.
Methods: The study included 22 wrists of 19 patients with RA and 10 wrists of nine patients with OA. Pain, grip strength and range of motion of the wrist were examined clinically. For the evaluation of the stability of the carpus, ulnar stump and bone union, parameters were measured using radiographs. Shortened disabilities of the arm, shoulder and hand questionnaire (QuickDASH) was used for functional evaluation.
Results: Wrist pain reduced in all cases, and bone union was achieved in all wrists. The QuickDASH score significantly improved in both patients with RA and OA. In patients with RA, the range of motion increased significantly with regard to supination but decreased significantly with regard to palmar flexion. Carpal alignment and ulnar stump stability were maintained well at one-year follow-up.
Conclusion: The Sauvé–Kapandji procedure for treating disorders of the distal radioulnar joint DRUJ showed good results clinically and radiographically, irrespective of RA or OA. 相似文献
Objectives: To determine the tentative diagnostic criteria and disease severity classification for Castleman disease (CD) and describe the clinical and pathologic features among human herpesvirus 8 (HHV-8) negative idiopathic multicentric CD (iMCD) in the Japanese population.
Methods: We established the working groups for the research of CD in Japan and had meetings to discuss and define the tentative diagnostic criteria and disease severity classification for CD. We subsequently analyzed 142 patients classified into iMCD by using the nationwide Japanese patient registry.
Results: We proposed the preliminary diagnostic criteria and disease severity classification for CD based on our discussion. In addition, we made a proposal for the disease activity score. We identified clinical and pathological features of patients with iMCD diagnosed by these diagnostic criteria. In the disease severity classification, 37, 33 and 30% patients were categorized into mild, moderate and severe diseases, respectively.
Conclusion: This is the first proposal for diagnosis and classification of CD by the Japanese group. Further studies are required to validate whether they can distinguish CD from other inflammatory diseases and to determine their sensitivity and specificity. 相似文献
Pro-phenol oxidase [pro-PO; zymogen of phenol oxidase (monophenol, L-dopa:oxygen oxidoreductase, EC 1.14.18.1)] is present in the hemolymph plasma of the silkworm Bombyx mori. Pro-PO is a heterodimeric protein synthesized by hemocytes. A specific serine proteinase activates both subunits through a limited proteolysis. The amino acid sequences of both subunits were deduced from their respective cDNAs; amino acid sequence homology between the subunits was 51%. The deduced amino acid sequences revealed domains highly homologous to the copper-binding site sequences (copper-binding sites A and B) of arthropod hemocyanins. The overall sequence homology between silkworm pro-PO and arthropod hemocyanins ranged from 29 to 39%. Phenol oxidases from prokaryotes, fungi, and vertebrates have sequences homologous to only the copper-binding site B of arthropod hemocyanins. Thus, silkworm pro-PO DNA described here appears distinctive and more closely related to arthropod hemocyanins. The pro-PO-activating serine proteinase was shown to hydrolyze peptide bonds at the carboxyl side of arginine in the sequence-Asn-49-Arg-50-Phe-51-Gly-52- of both subunits. Amino groups of N termini of both subunits were indicated to be N-acetylated. The cDNAs of both pro-PO subunits lacked signal peptide sequences. This result supports our contention that mature pro-PO accumulates in the cytoplasm of hemocytes and is released by cell rupture, as for arthropod hemocyanins. 相似文献
We evaluated the efficacy of pleurodesis using OK-432 (Picibanil) for the treatment of pneumothorax associated with pulmonary lymphangioleiomyomatosis (LAM). Seven episodes of pneumothorax in five patients with LAM were treated with pleurodesis using OK-432. First, all patients underwent tube thoracostomy drainage. After drainage, 5 or 10 KE of OK-432 was administered via the tube. If incomplete lung expansion or a continuous air leak occurred, an additional 5 KE of OK-432 was administered. Of the five patients, two developed pneumothorax for the first time and three had a history of previous pneumothorax. The mean total dose of OK-432 administered was 13.6 KE, and the mean period of tube drainage was 11 days. The only recurrence of ipsilateral pneumothorax after OK-432 pleurodesis was observed seven years and eight months later in association with chronic respiratory failure in one patient. This patient was successfully treated with repeated pleurodesis using OK-432 during mechanical ventilation, and no recurrence has developed in the eight years since then. The main side effects of the procedure with OK-432 were fever and chest pain, which were well controlled by non-steroidal anti-inflammatory drugs. The study concluded that pleurodesis with OK-432 was an effective and safe treatment for intractable and recurrent pneumothorax associated with LAM. 相似文献
We investigated the effects of metformin on myocardial metabolism during ischemia by 31P-nuclear magnetic resonance (NMR) in isolated rabbit hearts. Metformin was administered 60 min prior to induction of global ischemia, or in combination with a nitric oxide synthase inhibitor, N(G)-nitro-L-arginine methyl ester (L-NAME), at 5 min or 60 min prior to the ischemia. Normothermic global ischemia was then carried out for 45 min. Twenty-eight hearts were divided into 4 experimental groups consisting of 7 hearts each: a control (C) group; an M group receiving metformin treatment alone; an M+L (5) group receiving metformin treatment with L-NAME at 5 min before ischemia; and an M+L (60) group receiving metformin treatment with L-NAME at 60 min before ischemia. During ischemia, the decrease in adenosine triphosphate (ATP) was significantly inhibited in the M group in comparison with the C group (p < 0.01). However, this preservation of ATP in the M group was inhibited in the M+L (5) group during ischemia. In contrast, in the M+L (60) group, this preservation of ATP in the M group was not inhibited during, but not at the end of, ischemia. These results suggest that metformin has a significant beneficial effect for improving the myocardial energy metabolism during myocardial ischemia. This cardioprotection may be more dependent on nitric oxide synthase during ischemia than during pre-ischemia. 相似文献
A 53-year-old male was admitted to our hospital complaining of high fever with chillness, cough and dyspnea after traveling to Arizona in the United States. The chest X-ray films taken on admission showed consolidation in the right middle lung field and bilateral nodular shadows. The laboratory data revealed an increase in white blood cell counts with eosinophilia, and a rise in erythrocyte sediment rate and serum C-reactive protein. The biopsied lung specimen by video-assisted thoracoscopic surgery showed granulomatous inflammation consisting of eosinophils and giant cells. In addition, typical spherules filled with endopores were detected in the specimen. The diagnosis of primary pulmonary coccidioidomycosis was made. After the treatment of a three months' regimen with itraconazole at the daily dosage of 200 mg, the patient's symptoms, laboratory data and radiological findings markedly improved. 相似文献
Although Ca(2+)/calmodulin-dependent protein kinase-II (CaMK) is known to phosphorylate different Ca(2+) cycling proteins in the cardiac sarcoplasmic reticulum (SR) and regulate its function, the status of CaMK in heart failure has not been investigated previously. In this study, we examined the hypothesis that changes in the CaMK-mediated phosphorylation of the SR Ca(2+) cycling proteins are associated with heart failure. For this purpose, heart failure in rats was induced by occluding the coronary artery for 8 weeks, and animals with >30% infarct of the left ventricle wall plus septum mass were used. Noninfarcted left ventricle was used for biochemical assessment; sham-operated animals served as control. A significant depression in SR Ca(2+) uptake and release activities was associated with a decrease in SR CaMK phosphorylation of the SR proteins, ryanodine receptor (RyR), Ca(2+) pump ATPase (SR/endoplasmic reticulum Ca(2+) ATPase [SERCA2a]), and phospholamban (PLB) in the failing heart. The SR protein contents for RyR, SERCA2a, and PLB were decreased in the failing hearts. Although the SR Ca(2+)/calmodulin-dependent CaMK activity, CaMK content, and CaMK autophosphorylation were depressed, the SR phosphatase activity was enhanced in the failing heart. On the other hand, the cAMP-dependent protein kinase-mediated phosphorylation of RyR and PLB was not affected in the failing heart. On the basis of these results, we conclude that alterations in SR CaMK-mediated phosphorylation may be partly responsible for impaired SR function in heart failure. 相似文献
Elevated intraocular pressure (IOP) is one of the most important risk factors for the development of glaucoma, which is a progressive optic neuropathy. Lowering IOP is currently the only therapeutic approach to the therapy of glaucoma. Since the use of pilocarpine eye drops for glaucoma treatment was reported in the late 1870s, academic researchers and pharmaceutical companies attempted to discover new drugs with more potent, prolonged, and safer IOP‐reducing effects. These persistent efforts finally paid off, and prostanoids with FP‐receptor agonist activity were found to be very potent IOP‐lowering agents. To date, three prostanoids (latanoprost, travoprost and bimatoprost) have been launched in many countries, and now a new FP‐receptor agonist, tafluprost, is entering clinical development. All of these prostanoids are superior to the β‐adrenoceptor antagonists in their IOP‐lowering efficacy, and no severe side effects have been reported in their long‐term clinical use. In addition, tafluprost may be expected to improve ocular blood flow. Hence, prostanoids currently occupy center stage among glaucoma medications. It cannot be denied that in terms of efficacy, safety, patient compliance, and medical economy prostanoids are currently the first‐line medicines among ocular antihypertensive drugs. 相似文献
