Acute coronary syndromes due to involvement of the left main trunk usually present with subtotal occlusion and electrocardiographic pattern with predominant ST depression (non-ST-elevation myocardial infarction). The cases with complete occlusion frequently present an ST-elevation myocardial infarction pattern, but these patients usually die before reaching the hospital. We present a series of 7 patients with total left main trunk occlusion without collateral circulation showing ST-elevation myocardial infarction pattern. The electrocardiographic pattern is similar to left anterior descending coronary artery proximal occlusion to first septal and first diagonal but without ST elevation in V(1) and aVR because of left circumflex coronary artery compromise. In 4 (60%) of 7 of cases, there is also advanced right bundle-branch block plus superoanterior hemiblock. Despite severe clinical state at entrance (5/7 presented cardiac arrest/cardiogenic shock), 3 patients (43%) survived after percutaneous coronary intervention. 相似文献

Background
Several studies of autologous stem cell transplantation in primary refractory myeloma have produced encouraging results. However, the outcome of primary refractory patients with stable disease has not been analyzed separately from the outcome of patients with progressive disease.Design and Methods
In the Spanish Myeloma Group 2000 trial, 80 patients with primary refractory myeloma (49 with stable disease and 31 with progressive disease), i.e. who were refractory to initial chemotherapy, were scheduled for tandem transplants (double autologous transplant or a single autologous transplant followed by an allogeneic transplant). Patients with primary refractory disease included those who never achieved a minimal response (≥25% M-protein decrease) or better. Responses were assessed using the European Bone Marrow Transplant criteria.Results
There were no significant differences in the rates of partial response or better between patients with stable or progressive disease. However, 38% of the patients with stable disease at the time of transplantation remained in a stable condition or achieved a minimal response after transplantation versus 7% in the group with progressive disease (P=0.0017) and the rate of early progression after transplantation was significantly higher among the group with progressive disease at the time of transplantation (22% versus 2%; P=0.0043). After a median follow-up of 6.6 years, the median survival after first transplant of the whole series was 2.3 years. Progression-free and overall survival from the first transplant were shorter in patients with progressive disease (0.6 versus 2.3 years, P=0.00004 and 1.1 versus 6 years, P=0.00002, respectively).Conclusions
Our results show that patients with progressive refractory myeloma do not benefit from autologous transplantation, while patients with stable disease have an outcome comparable to those with chemosensitive disease. (ClinicalTrials.gov:) NCT00560053相似文献64.

Background and aimsPrompt identification of parapneumonic effusions has immediate therapeutic benefits. We aimed to assess whether C-reactive protein (CRP) and routine biochemistries in pleural fluid are accurate markers of parapneumonic effusions, and to evaluate their properties as indicators for drainage (complicated parapneumonic effusion).MethodsA retrospective review of 340 non-purulent parapneumonic effusions and 1,659 non-parapneumonic exudates from a single center was performed and the discriminative properties of pleural fluid routine biochemistries and, when available, CRP were evaluated. CRP, along with classical fluid parameters, was also applied to classify patients as having complicated or uncomplicated parapneumonic effusions. ROC analysis established the threshold of CRP for discriminating between groups.ResultsPleural fluids with neutrophilic predominance and CRP levels > 45 mg/dL were most likely to be parapneumonic in origin (likelihood ratio = 7.7). When attempting to differentiate non-purulent complicated from uncomplicated effusions, a CRP > 100 mg/L had the same performance characteristics (area under the curve = 0.81) as the widely accepted biochemistries pH and glucose. Combinations of CRP with pH or glucose resulted in incrementally discriminating values, pertaining to either sensitivity (75–80%) or specificity (97%), for complicated effusions.ConclusionPleural fluid CRP may be a useful adjunctive test in pleural effusions, both as a marker of parapneumonics and, particularly, as a differentiator between complicated and uncomplicated effusions. 相似文献

AIM: To compare rifaximin and insulin-like growth factor (IGF)-1 treatment of hyperammonemia and brain edema in cirrhotic rats with portal occlusion.METHODS: Rats with CCl4-induced cirrhosis with ascites plus portal vein occlusion and controls were randomized into six groups: Cirrhosis; Cirrhosis + IGF-1; Cirrhosis + rifaximin; Controls; Controls + IGF-1; and Controls + rifaximin. An oral glutamine-challenge test was performed, and plasma and cerebral ammonia, glucose, bilirubin, transaminases, endotoxemia, brain water content and ileocecal cultures were measured and liver histology was assessed.RESULTS: Rifaximin treatment significantly reduced bacterial overgrowth and endotoxemia compared with cirrhosis groups, and improved some liver function parameters (bilirubin, alanine aminotransferase and aspartate aminotransferase). These effects were associated with a significant reduction in cerebral water content. Blood and cerebral ammonia levels, and area-under-the-curve values for oral glutamine-challenge tests were similar in rifaximin-treated cirrhotic rats and control group animals. By contrast, IGF-1 administration failed to improve most alterations observed in cirrhosis.CONCLUSION: By reducing gut bacterial overgrowth, only rifaximin was capable of normalizing plasma and brain ammonia and thereby abolishing low-grade brain edema, alterations associated with hepatic encephalopathy. 相似文献

The purpose of this study was to establish the microbial aetiology and outcomes of patients with community-acquired pneumonia (CAP) treated as outpatients after presenting to a hospital emergency care unit. A prospective observational study was carried out in the Hospital Clinic of Barcelona (Barcelona, Spain). All consecutive cases of CAP treated as outpatients were included. 568 adult outpatients with CAP were studied (mean±sd age 47.2±17.6 yrs; 110 (19.4%) were aged ≥65 yrs). Aetiological diagnoses were established in 188 (33.1%) cases. Streptococcus pneumoniae was the most frequent pathogen followed by Mycoplasma pneumoniae and respiratory viruses. Legionella was detected in 13 (2.3%) cases. More than one causative agent was found in 17 (9.0%) patients. Mortality was low (three (0.5%) patients died) and other adverse events were rare (30 (5.2%) patients had complications, 13 (2.3%) were re-admitted and treatment failed in 13 (2.3%)). Complications were mostly related to pleural effusion and empyema, and re-admissions and treatment failures to comorbidities. Outpatients with CAP have a characteristic microbial pattern. Regular antipneumococcal coverage remains mandatory. Treatment failures and re-admissions are rare and may be reduced by increased attention to patients requiring short-term observation in the emergency care unit and in the presence of pleural effusion and comorbidities. 相似文献

Background
Idiopathic portal hypertension is a rare cause of portal hypertension, frequently misdiagnosed as cryptogenic cirrhosis. This study evaluates specific findings at hepatic vein catheterisation or liver stiffness in idiopathic portal hypertension.Methods
39 cases of idiopathic portal hypertension patients were retrospectively reviewed. Hepatic vein catheterisation and liver stiffness measurements were compared to matched patients with cirrhosis and portal hypertension, and non-cirrhotic portal vein thrombosis, included as controls.Results
Hepatic vein-to-vein communications were found in 49% idiopathic portal hypertension patients precluding adequate hepatic venous pressure gradient measurements in 12. In the remaining 27 patients, mean hepatic venous pressure gradient (HVPG) was 7.1 ± 3.1 mmHg. Only 5 patients had HVPG ≥ 10 mmHg. HVPG was markedly lower than in cirrhosis (17 ± 3 mmHg, p < 0.001). Mean liver stiffness in idiopathic portal hypertension was 8.4 ± 3.3 kPa; significantly higher than in non-cirrhotic portal vein thrombosis (6.4 ± 2.2 kPa, p = 0.009), but lower than in cirrhosis (40.9 ± 20.5 kPa, p = 0.005). Only 2 idiopathic portal hypertension patients had liver stiffness >13.6 kPa.Conclusions
Patients with idiopathic portal hypertension frequently have hepatic vein-to-vein communications and, despite unequivocal signs of portal hypertension, HVPG and liver stiffness values much lower than the cut-off for clinical significant portal hypertension in cirrhosis. These findings oblige to formally rule-out idiopathic portal hypertension in the presence of signs of portal hypertension. 相似文献68.

The phonology of two groups of SLI (n =5) and LD (n =5) children was analysed at age 3 and compared with two control groups: an age control (n =5) and a language level control (measured using the MLU-W) (n =5). Children with SLI and LD showed a delay in the acquisition of segments, syllabic structures and word structures, and in the simplification processes, compared with their age control group. However, SLI children also displayed significant differences vis-à-vis their language level controls, mainly in early acquisitions: vowels, nasals and stops at the segmental level, and in CV structures at the syllabic level. There is also a simplification process that seems to be more prevalent in these children than in their language level controls, namely, the deletion of unstressed syllables, mainly initial ones. The results enable SLI to be distinguished from LD and suggest that the development of SLI phonology is deviant. This deviation is interpreted as being a plateau in early acquisitions when later acquisitions have already appeared. The results are considered in the light of Leonard's surface hypothesis and an exclusively linguistic cause for this disorder is ruled out. 相似文献
