BACKGROUND: Rotator cuff disease is uncommon in primary glenohumeral osteoarthritis. Consequently, the prognostic implications of rotator cuff disease in patients undergoing prosthetic replacement for the treatment of primary glenohumeral osteoarthritis are uncertain. The purpose of this study was to report the effects of the condition of the supraspinatus tendon and the rotator cuff musculature on the results of shoulder arthroplasty in the treatment of primary osteoarthritis. METHODS: Five hundred and fifty-five shoulders in 514 patients who had an arthroplasty for the treatment of primary glenohumeral osteoarthritis as part of a multicenter study were evaluated. Forty-one shoulders had a partial-thickness tear of the supraspinatus, and forty-two had a full-thickness tear. Ninety shoulders had moderate (stage-2) fatty degeneration of the infraspinatus, and nineteen had severe (stage-3 or 4) degeneration. Eighty-four shoulders had moderate fatty degeneration of the subscapularis, and fifteen had severe degeneration. The influence of the condition of the supraspinatus tendon and the infraspinatus and subscapularis musculature on the postoperative outcome was evaluated with respect to the scores according to the system of Constant and Murley, active mobility, subjective satisfaction, radiographic result, and rate of complications. RESULTS: The shoulders were evaluated at a mean of 43.1 months postoperatively. With the numbers available, supraspinatus tears were not found to influence the postoperative outcome with respect to the total Constant score, active mobility, subjective satisfaction, radiographic result, or rate of complications. Additionally, the treatment of these tears did not markedly influence the outcome parameters. Conversely, both shoulders with moderate fatty degeneration and those with severe degeneration of the infraspinatus were associated with poorer results than those with no degeneration with respect to the total Constant score (p < 0.0005), active external rotation (p < 0.0005), active forward flexion (p = 0.001), and subjective satisfaction (p = 0.031). Similar although less dramatic results were seen with fatty degeneration of the subscapularis. CONCLUSIONS: This study demonstrates that minimally retracted or nonretracted rotator cuff tears that are limited to the supraspinatus tendon do not appreciably affect most shoulder-specific outcome parameters in shoulder arthroplasty performed for the treatment of primary osteoarthritis. Conversely, fatty degeneration of the infraspinatus and, less importantly, subscapularis musculature adversely affects many of these parameters.  相似文献

BackgroundAntibodies to cyclic citrullinated peptide (anti-CCP) and IgM rheumatoid factor (IgM-RF) are well-established serological markers for rheumatoid arthritis (RA). Lupus-like disease with antinuclear antibodies (ANA) has been reported during TNFα antagonist therapy. Our objectives were to investigate the effect of infliximab therapy on these three autoantibodies in patients with established RA and to look for correlations linking IgM-RF and anti-CCP titres to a treatment response (defined as a good or moderate EULAR response) after 48 weeks of infliximab therapy.MethodsThirty-six patients with long-standing RA not responding to disease-modifying anti-rheumatic drugs (DMARDs) received intravenous infliximab (starting dose: 3 mg/kg) at 0, 2, and 6 weeks then at 8-week intervals, in combination with a DMARD. At baseline, week 24, and week 48, C-reactive protein (CRP) and the erythrocyte sedimentation rate (ESR) were determined and the disease activity score (DAS28) was calculated. Serum samples collected at the same time points were used to measure anti-CCP (commercial second-generation ELISA), IgM-RF (quantitative nephelometric assay), and ANA (indirect immunofluorescence in HEp2 cells). Correlations linking baseline autoantibody titres to changes in autoantibody levels were examined.ResultsAt baseline, tests were positive for anti-CCP in 31/36 (94.6%) patients, IgM-RF in 29/36 (80.5%) patients, and ANA in 16/36 (44%) patients. IgM-RF titres decreased significantly (p < 0.001), whereas anti-CCP showed little change (p = 0.053). ANA titres increased significantly (p < 0.001). The treatment response was not associated with changes in anti-CCP or IgM-RF titres during infliximab therapy (OR for a response in patients with a 50% anti-CCP decrease, 0.77 [95%CI, 0.16–3.58]; OR for a response in patients with a 50% IgM-RF decrease, 0.82 [95%CI, 0.16–4.13]).ConclusionsDuring infliximab therapy used to treat established RA, IgM-RF titres showed larger decreases than anti-CCP titres. Changes in IgM-RF and anti-CCP failed to correlate with the 48-week treatment response.  相似文献

PURPOSE: During liver transplantation, excessive blood losses are correlated with increased morbidity and mortality. Blood losses are particularly high in the case of urgent liver transplantation for fulminant hepatic failure (FHF). Recombinant activated factor VII (rFVIIa) has shown promise in treating the coagulopathy of liver disease. We review our experience with the use of rFVIIa in treating the coagulopathy of FHF during urgent liver transplantation. CLINICAL FEATURES: We report four patients with FHF who met King's College criteria for liver transplantation and in whom rFVIIa was used after conventional means for treating the associated coagulopathy had failed. In all patients, the coagulation defect was corrected by rFVIIa. However, thrombotic complications occurred in two patients (myocardial ischemia and portal vein thrombosis) and the implication of rFVIIa cannot be excluded. CONCLUSION: We conclude that rFVIIa is effective in the correction of the coagulopathy associated with FHF. However, thrombotic events are of concern and therefore, further studies are warranted to define the safety of rFVIIa in that setting.  相似文献

BACKGROUND: The aim of this retrospective study was to evaluate clinical presentation and long-term outcome of patients treated surgically for complicated liver hydatid cysts. PATIENTS AND METHODS: Eighty-four patients with liver hydatid cysts underwent an operation at the Geneva University Hospital between 1980 and 1999. Clinical presentation, postoperative morbidity, mortality, and long-term recurrence rate were evaluated. RESULTS: Among the 84 patients with liver hydatid disease, 35 patients (41%) presented complicated cysts (ie, cysts that had developed a fistula into adjacent structures or organs). In most patients, the fistula communicated with the biliary tree (n = 25), but we also observed communication with the right lung (n = 3), the right diaphragm (n = 2), liver parenchyma (n = 1), and peritoneal cavity (n = 1). Complete removal of the cystic disease was possible in 24 of 35 patients (70%). In 11 patients, fragments of cysts were not removed because of their location adjacent to main vessels. Postoperatively, 8 patients (23%) developed a severe complication (grade II and III). There were no postoperative deaths, and no recurrences of hydatid disease were observed with a median follow-up of 8.6 years (complete follow-up was obtained in 69% of patients). CONCLUSIONS: Complicated liver hydatid disease is frequent and was observed in almost half of patients operated for liver hydatid cysts at our center. Using a surgical strategy aimed at complete removal of cystic and pericystic tissue with simultaneous treatment of the fistulous tract, we observed 23% postoperative morbidity, no mortality, and no recurrence of disease with a median follow-up of >8 years.  相似文献

BACKGROUND: Only 2 large (more than 100 patients) prospective trials comparing pancreatogastrostomy (PG) with pancreatojejunostomy (PJ) after pancreatoduodenectomy (PD) have been reported until now. One nonrandomized study showed that there were less pancreatic and digestive tract fistula with PG, whereas the other, a randomized trial from a single high-volume center, found no significant differences between the two techniques. METHODS: Single blind, controlled randomized, multicenter trial. The main endpoint was intra-abdominal complications (IACs). RESULTS: Of 149 randomized patients, 81 underwent PG and 68 PJ. No significant difference was found between the two groups concerning pre- or intraoperative patient characteristics. The rate of patients with one or more IACs was 34% in each group. Twenty-seven patients sustained a pancreatoenteric fistula (18%), 13 in PG (16%; 95% confidence interval [CI] 8-24%) and 14 in PJ (20%; 95% CI 10.5-29.5%). No statistically significant difference was found between the 2 groups concerning the mortality rate (11% overall), the rate of reoperations and/or postoperative interventional radiology drainages (23%), or the length of hospital stay (median 20.5 days). Univariate analysis found the following risk factors: (1) age > or =70 years old, (2) extrapancreatic disease, (3) normal consistency of pancreas, (4) diameter of main pancreatic duct <3 mm, (5) duration of operation >6 hours, and (6) a center effect. Significantly more IAC, pancreatoenteric fistula, and deaths occurred in one center (that included the most patients) (P = .05), but there were significantly more high-risk patients in this center (normal pancreas consistency, extrapancreatic pathology, small pancreatic duct, higher transfusion requirements, and duration of operation >6 hours) compared with the other centers. In multivariate analysis, the center effect disappeared. Independent risk factors included duration of operation >6 hours for IAC and for pancreatoenteric fistula (P = .01), extrapancreatic disease for pancreatoenteric fistulas (P < .04), and age > or =70 years for mortality (P < .02). CONCLUSIONS: The type of pancreatoenteric anastomosis (PJ or PG) after PD does not significantly influence the rate of patients with one or more IAC and/or pancreatic fistula or the severity of complications.  相似文献

Cardiovascular disease (CVD) is the leading cause of mortality in women. In fact, CVD is responsible for a third of all deaths of women worldwide and half of all deaths of women over 50 years of age in developing countries. The prevalence of CVD risk factor precursors is increasing in children. Retrospective analyses suggest that there are some clinically relevant differences between women and men in terms of prevalence, presentation, management and outcomes of the disease, but little is known about why CVD affects women and men differently. For instance, women with diabetes have a significantly higher CVD mortality rate than men with diabetes. Similarly, women with atrial fibrillation are at greater risk of stroke than men with atrial fibrillation. Historically, women have been underrepresented in clinical trials. The lack of good trial evidence concerning sex-specific outcomes has led to assumptions about CVD treatment in women, which in turn may have resulted in inadequate diagnoses and suboptimal management, greatly affecting outcomes. This knowledge gap may also explain why cardiovascular health in women is not improving as fast as that of men. Over the last decades, mortality rates in men have steadily declined, while those in women remained stable. It is also becoming increasingly evident that gender differences in cultural, behavioural, psychosocial and socioeconomic status are responsible, to various degrees, for the observed differences between women and men. However, the interaction between sex-and gender-related factors and CVD outcomes in women remains largely unknown.  相似文献

Between 1985 and 1988 45 patients with descending thoracic or thoracoabdominal aortic aneurysms underwent selective arteriography of the intercostal and lumbar arteries to delineate preoperatively the artery of Adamkiewicz and the thoracic radicular artery. Identification of these vessels failed in five patients (11%), was considered complete in 31 patients (69%) and incomplete in nine (20%). Selective arteriography classified these patients into four groups: groups A and B--the artery of Adamkiewicz arose respectively above and below the zone of operation; group C--the artery arose directly from the segment to be operated; and group D--origin could not be determined. All 30 patients in group C underwent a spinal cord revascularization procedure (complete in 20 cases, incomplete in 10). Spinal cord complications occurred in 9/45 patients (20%). No spinal cord complications occurred in groups A and B; their incidence was 5% in group C when revascularization was complete, and 50% when revascularization was incomplete; and 60% had complications in group D (p less than 0.01). Spinal cord complications were more frequent (p less than 0.05) when the artery of Adamkiewicz arose from an intercostal or lumbar artery obliterated at its aortic origin but filled through collaterals or when spinal cord circulation was interrupted for more than 45 minutes. This study confirms the importance of preserving arterial supply to the spinal cord during repair of descending thoracic and thoracoabdominal aneurysms. The information obtained from spinal cord arteriography allows the prediction of complications and informs the choice of the appropriate surgical technique.  相似文献

PURPOSE: To estimate the potential public health impact of treatment with new medications intended to preserve vision in patients with neovascular age-related macular degeneration (AMD). METHODS: A Markov model was used to simulate the natural history of AMD over the lifetime of patients with diagnosed neovascular AMD from clinical trials and epidemiologic surveys. It applied to a cohort of patients aged 75 years, with newly diagnosed neovascular AMD in one eye, whose visual acuity was 0.7 logMAR. Probabilities were calculated for the risk of AMD in the remaining eye and for premature mortality. Results of the model were expressed as the duration of low vision (worse eye VA>1.0 and better eye VA>0.7 logMAR) and blindness (bilateral VA >1.0 logMAR). Health consequences of blindness and low vision were estimated for depression, hip fractures, institutionalization, and life expectancy. RESULTS: For AMD patients with a 50% probability of VA >1.0 logMAR at 1 year, in one eye, the probability of lifetime bilateral blindness was >47%. The patients would live approximately 7 years with monocular vision >1.0 logMAR and an additional 4 years with bilateral blindness and a >15% probability of depression due to AMD. Life expectancy was decreased by approximately 2 years, >90/1000 patients would sustain a new hip fracture, and 1.5% of the patients would require institutional care for visual impairment due to AMD. To achieve a defined public health outcome (visual impairment and consequent comorbidity), it was necessary for the VA effectiveness of new treatments to increase in parallel with disease severity. CONCLUSIONS: Comorbidity related to visual impairment contributes significantly to the public health impact of AMD. Aggressive lesions need highly effective treatments. Models may be used to compare the public health impact of placebo-controlled clinical trial results.  相似文献

OBJECTIVES--To determine the effectiveness of intramuscular (IM) ceftriaxone sodium in the treatment of chronic donovanosis, and the acceptability to patients and staff of supervised outpatient treatment in rural clinics. METHODS--We collected demographic and sexual health data from participants using a standard questionnaire, and recorded their donovanosis lesions at baseline using genital diagrams. Treatment consisted of a single daily IM injection of 1 g ceftriaxone diluted in 2 ml of 1% lignocaine. Clinic staff followed patients for between three and 12 months, enabling the detection of late recurrences. SETTING--Rural Aboriginal communities in central Australia. PARTICIPANTS--The study describes eight women and four men with chronic donovanosis in detail, and summarises the outcome in 12 additional cases. All cases presented with advanced lesions which had failed to heal on the standard oral antibiotic regimens used in the region. RESULTS--The mean duration of infection was 3.0 years (SD 1.9 years), and between four and ten courses of antibiotics had been prescribed for six of the 12 patients. Patients received between 7-26g of ceftriaxone sodium. Clinical improvement was dramatic in most lesions, and four patients healed completely without recurrence after a total 7-10g of ceftriaxone. Mild recurrences responded to further ceftriaxone or short courses of oral antibiotics. Treatment was well tolerated, and both patient and staff compliance high. CONCLUSION--Donovanosis is an important cause of chronic genital ulceration in central Australia, and is potentially an important risk factor for HIV transmission in Aboriginal communities. The pharmacokinetics and safety profile of ceftriaxone make it a useful and cost-effective agent in the ambulatory management of donovanosis, especially in remote communities. Supervised multidrug regimens of two or more long-acting agents may provide the best answer in donovanosis, administered through the existing health care infrastructure.  相似文献
