Transcutaneous oximetry has been used to define the level of amputation in arteritic patients, with discrepant results. We have studied preoperative statix oximetry in 33 arteritic patients at the Leriche-Fontaine Stage IV, who underwent 36 amputations (thighs = 6, Legs+Symes = 14, transmetatarsal = 7, toes = 9). Oximetry included the measurement, at the level of amputation, of the transcutaneous partial oxygen pressure (tc pO2), of the tissue oxygenation ratio (TOR), preferably with a precordial electrode, of the tc pO2 gain after oxygen inhalation and of the gain ratio with the reference electrode. Two patients died postoperatively, the amputation stump did not heal in another 8 patients. The tc pO2 value was 36.6 +/- 16.2 mm Hg in the healed group and 21.1 +/- 19.9 mm Hg in the non healed group. The TOR respectively was 71.2 +/- 32.7% and 38.6 +/- 29.9% in these two groups. These differences were statistically significant. The difference between the two groups in the measurements made after the oxygenation test was not statistically significant. With a tc pO2 threshold at 26 mm Hg, the sensitivity was 73% and the specificity 75%, the positive predictive value 90%, the negative predictive value 46% and the value of the test 73.5%. The thresholds calculated to be 56% for TOR, 11 mm Hg for the gain and 32% for the gain ratio, did not improve the performances of oximetry. In our study, the tc pO2 was the parameter that best allowed predicting healing was obtained with smaller values than the threshold. Other elements such as the general condition and diabetes have played a role in the prognosis. 相似文献

OBJECTIVES: To assess prevalence, characteristics, and long-term outcome of interstitial lung disease (ILD) in polymyositis (PM) and dermatomyositis (DM). To determine predictive variables of ILD course in PM/DM, and to define both clinical and biochemical features associated with ILD onset in PM/DM. METHODS: The medical records of 156 consecutive PM/DM patients in 3 medical centers were reviewed. RESULTS: Thirty-six PM/DM patients (23.1%) developed ILD. We observed that 19.4% of patients with ILD had resolution of pulmonary disorders, whereas 25% experienced ILD deterioration. Morbidity and mortality rates were as high as 13.9% and 36.4%, respectively, in PM/DM patients with ILD. Parameters of PM/DM that related to ILD poor outcome were identified as follows: Hamman-Rich-like pattern, initial diffusing capacity of carbon monoxide <45%, neutrophil alveolitis, and histologic usual interstitial pneumonia. Additionally, for the group with ILD, polyarthritis, higher values of erythrocyte sedimentation rate and C-reactive protein, presence of anti-Jo-1 antibody, and characteristic microangiopathy were significantly more frequent. CONCLUSION: Our series underlines the high frequency of ILD in PM/DM patients, resulting in increased morbidity and mortality rates. It also indicates that PM/DM patients should routinely be screened for ILD, even those patients without anti-Jo-1 antibody, because 69% of our ILD patients were seronegative for the anti-Jo-1 antibody. Our findings further suggest that PM/DM patients presenting with factors predictive of ILD poor outcome may require more aggressive therapy. 相似文献

The authors report a case of hypersensitivity angiitis presenting with cutaneous, muscular, articular, and renal signs. They suggest a possible etiological mechanism for such disorders: a circulating immune-complex disease, and criticize the often improper interpretation of the results of lymphoblast transformation tests. Hypersensitivity angiitis, "ground base disease", requires investigation for possible underlying immunity abnormalities or neoplasms. 相似文献

3 new cases of dermatomyositis associated with diffuse interstitial pulmonary fibrosis and, more exceptionally, with Sj?gren's syndrome are reported. The pulmonary fibrosis observed in patients with dermatomyositis differs from that found in other connective tissue diseases in that it follows a more acute course and may respond to corticosteroids. Thus, in 2 of these patients treated with corticosteroids (combined in 1 case with cyclophosphamide) the high percentage of lymphocytes and polymorphonuclears in the broncho-alveolar lavage fluid, which reflects alveolitis activity, was reduced and the pulmonary fibrosis was cured in one patient and stabilized in the other. 相似文献

PURPOSE: The present study was aimed at assessing the influence of age on clinical and biological features of systemic sclerosis. METHODS: This retrospective study included 151 consecutive patients with systemic sclerosis. The median age at diagnosis was 50.0 years (range: 10-84 years). Patients were divided into two groups according to their age (lower than 50.0 years of age: 73 patients, equal to or above 50 years of age: 78 patients). The following features were compared between the two groups: gender, disease duration, extent of skin sclerosis, Crest syndrome, lung fibrosis, secondary Sj?gren's syndrome, antinuclear, anticentromere, and anti-Scl70 antibodies. RESULTS: The disease duration was significantly higher in patients over 50 years of age (7.1 +/- 6.8 years vs 5.5 +/- 5.0 years, P < 0.05). Crest syndrome, secondary Sj?gren's syndrome and anticentromere antibodies were significantly more common in patients over 50 years of age (17/73 vs 30/78, P < 10(-2); 9/73 vs 20/78, P < 10(-2), and 19/73 vs 31/78, P < 0.05; respectively). Anti-Scl70 antibodies were significantly more common in patients under 50 years of age (17/73 vs 10/78, P < 10(-2)). No significant difference was found in regard to the other features. CONCLUSION: The clinical and biological patterns of systemic sclerosis are different according to the age at disease onset. Crest syndrome including anticentromere antibodies and Sj?gren's syndrome is more common in elderly patients, while anti- Scl-70 antibodies are more common in younger patients. This suggests the involvement of various mechanisms in the pathogenesis of systemic sclerosis, and that these mechanisms may depend on the age. 相似文献

There are few reports of amyloidosis diagnosed by deliberate biopsy of accessory salivary glands. Usually, a biopsy performed for dry mouth syndrome reveals an unsuspected amyloidosis. We report the case of 2 patients with lambda-type light chain monoclonal gammapathy complicated by generalized amyloidosis and in whom biopsy of the accessory salivary glands showed signs of amyloidosis. In the first patient accessory salivary gland biopsy was performed because these glands were enlarged, and the monoclonal dysglobulinaemia was subsequently diagnosed by serum immunoelectrophoresis. In the second patient with nephrotic syndrome, renal biopsy could not be carried out owing to the presence of a renal malformation; amyloidosis was confirmed by periumbilical fat aspiration, and a systematic biopsy of accessory salivary glands also showed evidence of amyloidosis. Biopsy of accessory salivary glands seems to be a particularly simple and safe method to detect generalized amyloidosis in patients with chronic inflammatory disease or monoclonal dysglobulinaemia. 相似文献
