After performing abdominal CT and gastric passage film, it was hypothesized that clinical manifestation was related to gastric malrotation. The latter was forced by the huge left pleural effusion. Draining the pleural effusion may be complicated by a trapped lung, an adverse effect where the lung does not expand post drainage. After considering the palliative therapeutic options the effusion was drained, the stomach recoiled to its anatomical position, gastric malrotation was relieved, and the patient resumed oral nutrition. Though gastric malrotation due to a huge, malignant left pleural effusion is rare, it should be considered as more patients are being treated for lung cancer.展开更多

Use of lung ultrasound (LUS) in resource-rich ICUs is still under investigation. The present study compares the utility of LUS to that of CXR in identifying pulmonary edema and pleural effusion in ICU patients. In addition, consolidation and pneumothorax were analyzed as secondary outcome measures. Material and Methods This is a prospective, single centric, observational study. Patients admitted in ICU were examined for lung pathologies, using LUS by a trained intensivist;and CXR done within 4 hours of each other. The final diagnosis was ascertained by an independent senior radiologist, based on the complete medical chart including clinical findings and the results of thoracic CT, if available. The results were compared and analyzed. Results Sensitivity, specificity and diagnostic accuracy of LUS was 95%, 94.4%, 94.67% for pleural effusion;and 98.33%, 97.78%, 98.00% for pulmonary edema respectively. Corresponding values with CXR were 48.33%, 76.67%, 65.33% for pleural effusion;and 36.67%, 82.22% and 64.00% for pulmonary edema respectively. Sensitivity, specificity and diagnostic accuracy of LUS was 91.30%, 96.85%, 96.00% for consolidation;and 100.00%, 79.02%, 80.00% for pneumothorax respectively. Corresponding values with CXR were 60.87%, 81.10%, 78.00% for consolidation;and 71.3%, 97.20%, 96.00% for pneumothorax respectively. Conclusion LUS has better diagnostic accuracy in diagnosis of pleural effusion and pulmonary edema when compared with CXR and is thus recommended as an effective alternative for diagnosis of these conditions in acute care settings. Our study recommends that a thoracic CT scan can be avoided in most of such cases.展开更多

If poorly treated, parapneumonic effusion evolves to the fibrino-purulent stage wherein antibiotic therapy alone becomes inadequate. Chest CT is the gold standard diagnostic imaging tool, however, in a resource-limited context, it may not be performed. Chest ultrasound can therefore be an alternative for drainage and intermittent follow-up of complicated parapneumonic pleural effusions. We report the case of a 4-year-old child who presented with cough, breathing difficulties and fever for over two weeks and in whom an initial chest X-ray revealed a left hemithorax white-out with an air-fluid level. Chest ultrasound revealed a left pleuropulmonary massive fluid collection with an encysted empyema. It also allowed ultrasound-guided pleural effusion drainage of a fibrino-purulent liquid which tested positive for Kocuria kristinae, a bacterium sensitive to gentamycin, vancomycin, norfloxacin and clindamycin. The next follow-up ultrasound checks showed improvement and the control chest X-ray performed one month later demonstrated pulmonary functional recovery. This case highlights the importance of ultrasound in the management and follow-up of this chest pathology in resource-limited settings.展开更多

The purpose of this study is to determine associated factors with the need for drainage of pleural effusion after diaphragm surgery. Methods and Materials: A retrospective chart review was undertaken in all women undergoing debulking surgery for stage IIIc/IV ovarian cancer from 2007-2009. Results: One hundred and eight patients were found to be eligible for the study, but 73 were the primary focus of this paper due to having undergone debulking surgery, including diaphragmatic surgery, from 2007-2009. All 73 had ablation with the argon beam coagulator, 7 had a full thickness resection, and 7 had extensive peritoneal peel. Five patients had preoperative effusions. Only 7 patients required chest drainage postoperatively. Pre-operative ascites correlated closely with postoperative effusion (p-value = 0.031) but not with drainage (p-value = 0.068). The mean age of patients requiring drainage was significantly older (73 years) than that of patients who did not require drainage (60 years) (p-value = 0.002). Conclusion: Older patients undergoing diaphragm surgery are more likely to require chest tube or thoracentesis due to concurrent symptoms. Pre-operative ascites correlates closely with the development of postoperative effusion after diaphragm surgery.展开更多

The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospec- tively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days 1 and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day 1 and ALT plus prealbumin on postoperative days 1 and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.展开更多

The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P【0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.展开更多

Objective: To demonstrate clinical features and outcome of pleural effusion. Methods: Prospective descriptive study was conducted involving 110 patients with pleural effusion admitted to a resource limited hospital in Ethiopia. Results: Males and females were almost equally represented. Cough, fever and weight loss were prominent presenting symptoms accounting 90, 77.3 and 77.3 percent respectively. Right side effusion was the common presentation 50 (45.5%). Forty (37.4%) patients had HIV infection among 107 tested. Tuberculosis was the commonest cause 78 (70.9%) followed by parapneumonic effusion 36 (32.7%) and empyema 27 (24.5%). Malignant pleural effusion was detected only in one patient. Eighty one (73.6%) improved from their illness and 7 (6.4%) died. Lympocytic pleural effusion found to be associated with tuberculosis (OR = 3.942 (1.527 - 10.179), P = 0.005. There were no associations between HIV infection, anemia, elevated ESR and side of pleural effusion with tuberculosis. Conclusion: Tuberculosis was the leading cause of pleural effusion in our setup even though etiologic diagnosis was difficult. Strengthening the laboratory and pathology services in the area is strongly recommended.展开更多

Methods: We measured adenosine deaminase (ADA) in PE, QuantiFERON TB-Gold In-Tube (QFT), and T-SPOT.TB using PB, and T-SPOT.TB using PE. The definite group of TB pleurisy included 12 patients and other disease group 33 patients. Main find-ings: Sensitivity for QFT using PB was 83% and specificity was 85%, sensitivity for T-SPOT.TB using PB was 92% and specificity was 82%, while sensitivity for ADA in PE was 83% and specificity was 76%. When we adopted the same cut-off level of a positive response for T-SPOT.TB as PB using PE, sensitivity for T-SPOT.TB using PE was 100% and specificity was 82%, respectively. Although there were no significant differences among the four diagnostic methods, sensitivity for T-SPOT.TB using PE gave the most accurate diagnosis of TB-definite patients compared to ADA in PE or QFT using PB. Conclusions: If we performed T-SPOT.TB using a local specimen from the infection site, we could obtain a higher sensitivity than IGRAs using PB or ADA in PE and the numbers of ESAT-6 and CFP-10-positive SFCs were 3 to 5 fold higher in PEMCs than in PBMCs. T-SPOT.TB using PE may become a useful diagnostic method for TB pleurisy.展开更多

ADA2<sub> </sub>is an isoenzyme,which is significantly raised in tuberculous pleural effusions both in the serum and pleural fluid.Conclusion:Estimation of ADA isoenzymes is redundant as a diagnostic aid over total ADA estimation in view of the limited improvements both in specificity and sensitivity patterns and also in term of cost-benefit ratio.展开更多

We assessed the efficacy of vascular endothelial growth factor (VEGF) in the differential diagnosis of patients with malignant and non-malignant pleural diseases. And also is assessed of the VEGF as a marker for success of chemical pleurodesis in malignant pleural effusion. Pleural effusions of 40 patients with a mean age of 55 (range, 26 to 78 years) were examined. A total of 20 patients had malignant pleural effusion;malignant mesothelioma (n=7), lung cancer (n=5) and metastatic malignancies (n=8). Twenty patients had benign pleural effusion;fibrinous pleuritis (n=6), tuberculosis (n=3) empyema (n=5), congestive heart failure (n=3), and acute pancreatitis (n=3). Definitive diagnosis was obtained in all cases with blind or open pleural biopsy, and cytological examination. VEGF levels were determined by enzyme-linked immunosorbent assay. The VEGF level of pleural effusion was comparably higher in the malignant group. The mean level of VEGF in patients with malignant pleural effusions (21.7 ± 1.8 ng/ml) was significantly (P <0.001) higher than that of (13.2 ± 1.5 ng/ml) non-malignant effusions. No significant difference was found regarding the VEGF levels and histological types in malignant pleural effusions. Negative correlation was observed between success rate of pleurodesis and VEGF level of pleural effusion (p= 0.015). The measurement of VEGF levels in pleural effusion may be useful to differentiate malignant from nonmalignant pleural effusions. VEGF level may also be an important prognostic marker for effective treatment of the patients who had malignant pleural effusions with pleurodesis. It is important issue in here whether VEGF could be useful in prognostication of outcome of chemical pleurodesis or not.展开更多

Methods Sixty-four pCVatients with EGFR-/ALK-lung adenocarcinoma with malignant pleural effusion(MPE) were admitted to the authors' hospital between January 2016 and June 2017. Patients were randomly divided into two groups: Endostar combined with pemetrexed/cisplatin(Endostar group); and bevacizumab plus pemetrexed/cisplatin(Bevacizumab group). They underwent thoracic puncture and catheterization, and MPE was drained as much as possible. Both groups were treated with pemetrexed 500 mg/m^2, intravenous drip(d1), cisplatin 37.5 mg/m^2 per time, intra-pleural injection(d1, d3). Patients in the Endostar group were treated with Endostar 30 mg per time, intra-pleural injection(d1, 3), and patients in the Bevacizumab group were treated with bevacizumab 5 mg/kg per time, intra-pleural injection(d1). Only one cycle of treatment was applied. MPE was extracted before treatment and on day 7 after treatment. The levels of vascular endothelial growth factor(VEGF) were determined using ELISA. Efficacy and side effects were evaluated according to the Response Evaluation Criteria in Solid Tumors(RECIST) version 1.1, and National Cancer Institute Common Terminology Criteria for Adverse Events(CTCAE) version 3.0 criteria. Results The objective response rates in the Endostar and Bevacizumab groups were 50.0% and 56.3%, respectively; there was no statistical difference between the groups(P > 0.05). After one cycle of treatment, the mean VEGF levels in MPE in both groups decreased significantly, and there was no significant difference in the degree of decline between the two groups(P > 0.05). In both groups, pre-treatment VEGF levels for patients achieving complete response were significantly higher than those for patients achieving stable disease + progressive disease(P < 0.05). No specific side effects were recorded. Conclusion Endostar and Bevacizumab demonstrated similar efficacy in controlling MPE in patients with EGFR-/ALK-lung adenocarcinoma through an anti-angiogenesis pathway, with tolerable side effects. The levels of VEGF in MPE could predict the efficacy of intra-pleural injection of anti-angiogenesis drugs.展开更多
文摘Mr M., 55-year-old, with metastatic adenocarcinoma of lung (stage IV) was admitted to the hospital after an earlier visit to oncology, where he presented with abdominal pain and distention suspected of having ascites for the first time. After performing abdominal CT and gastric passage film, it was hypothesized that clinical manifestation was related to gastric malrotation. The latter was forced by the huge left pleural effusion. Draining the pleural effusion may be complicated by a trapped lung, an adverse effect where the lung does not expand post drainage. After considering the palliative therapeutic options the effusion was drained, the stomach recoiled to its anatomical position, gastric malrotation was relieved, and the patient resumed oral nutrition. Though gastric malrotation due to a huge, malignant left pleural effusion is rare, it should be considered as more patients are being treated for lung cancer.
文摘Background and Aims While chest X-ray (CXR) has been a conventional tool in intensive care units (ICUs) to identify lung pathologies, computed tomography (CT) scan remains the gold standard. Use of lung ultrasound (LUS) in resource-rich ICUs is still under investigation. The present study compares the utility of LUS to that of CXR in identifying pulmonary edema and pleural effusion in ICU patients. In addition, consolidation and pneumothorax were analyzed as secondary outcome measures. Material and Methods This is a prospective, single centric, observational study. Patients admitted in ICU were examined for lung pathologies, using LUS by a trained intensivist;and CXR done within 4 hours of each other. The final diagnosis was ascertained by an independent senior radiologist, based on the complete medical chart including clinical findings and the results of thoracic CT, if available. The results were compared and analyzed. Results Sensitivity, specificity and diagnostic accuracy of LUS was 95%, 94.4%, 94.67% for pleural effusion;and 98.33%, 97.78%, 98.00% for pulmonary edema respectively. Corresponding values with CXR were 48.33%, 76.67%, 65.33% for pleural effusion;and 36.67%, 82.22% and 64.00% for pulmonary edema respectively. Sensitivity, specificity and diagnostic accuracy of LUS was 91.30%, 96.85%, 96.00% for consolidation;and 100.00%, 79.02%, 80.00% for pneumothorax respectively. Corresponding values with CXR were 60.87%, 81.10%, 78.00% for consolidation;and 71.3%, 97.20%, 96.00% for pneumothorax respectively. Conclusion LUS has better diagnostic accuracy in diagnosis of pleural effusion and pulmonary edema when compared with CXR and is thus recommended as an effective alternative for diagnosis of these conditions in acute care settings. Our study recommends that a thoracic CT scan can be avoided in most of such cases.
文摘Pleural effusion usually causes a diagnostic dilemma with a long list of differential diagnoses.Many studies found a high prevalence of pleural effusions in critically ill and mechanically ventilated patients,with a wide range of variable prevalence rates of up to 50%-60%in some studies.This review emphasizes the importance of pleural effusion diagnosis and management in patients admitted to the intensive care unit(ICU).The original disease that caused pleural effusion can be the exact cause of ICU admission.There is an impairment in the pleural fluid turnover and cycling in critically ill and mechanically ventilated patients.There are also many difficulties in diagnosing pleural effusion in the ICU,including clinical,radiological,and even laboratory difficulties.These difficulties are due to unusual presentation,inability to undergo some diagnostic procedures,and heterogenous results of some of the performed tests.Pleural effusion can affect the patient’s outcome and prognosis due to the hemodynamics and lung mechanics changes in these patients,who usually have frequent comorbidities.Similarly,pleural effusion drainage can modify the ICUadmitted patient’s outcome.Finally,pleural effusion analysis can change the original diagnosis in some cases and redirect the management toward a different way.
文摘BACKGROUND Viral pleurisy is a viral infected disease with exudative pleural effusions.It is one of the causes for pleural effusions.Because of the difficult etiology diagnosis,clinically pleural effusions tend to be misdiagnosed as tuberculous pleurisy or idiopathic pleural effusion.Here,we report a case of pleural effusion secondary to viral pleurisy which is driven by infection with epstein-barr virus.Viral infection was identified by metagenomic next-generation sequencing(mNGS).CASE SUMMARY A 40-year-old male with a history of dermatomyositis,rheumatoid arthritis,and secondary interstitial pneumonia was administered with long-term oral prednisone.He presented with fever and chest pain after exposure to cold,accompanied by generalized sore and weakness,night sweat,occasional cough,and few sputums.The computed tomography scan showed bilateral pleural effusions and atelectasis of the partial right lower lobe was revealed.The pleural fluids were found to be yellow and slightly turbid after pleural catheterization.Thoracoscopy showed fibrous adhesion and auto-pleurodesis.Combining the results in pleural fluid analysis and mNGS,the patient was diagnosed as viral pleuritis.After receiving Aciclovir,the symptoms and signs of the patient were relieved.CONCLUSION Viral infection should be considered in cases of idiopathic pleural effusion unexplained by routine examination.mNGS is helpful for diagnosis.
文摘Pleural effusion is a common complication of acute lung infection, with rising morbidity and mortality. If poorly treated, parapneumonic effusion evolves to the fibrino-purulent stage wherein antibiotic therapy alone becomes inadequate. Chest CT is the gold standard diagnostic imaging tool, however, in a resource-limited context, it may not be performed. Chest ultrasound can therefore be an alternative for drainage and intermittent follow-up of complicated parapneumonic pleural effusions. We report the case of a 4-year-old child who presented with cough, breathing difficulties and fever for over two weeks and in whom an initial chest X-ray revealed a left hemithorax white-out with an air-fluid level. Chest ultrasound revealed a left pleuropulmonary massive fluid collection with an encysted empyema. It also allowed ultrasound-guided pleural effusion drainage of a fibrino-purulent liquid which tested positive for Kocuria kristinae, a bacterium sensitive to gentamycin, vancomycin, norfloxacin and clindamycin. The next follow-up ultrasound checks showed improvement and the control chest X-ray performed one month later demonstrated pulmonary functional recovery. This case highlights the importance of ultrasound in the management and follow-up of this chest pathology in resource-limited settings.
文摘Pleural effusion is a commonly encountered respiratory disorder. In the majority of cases, a single causative agent is responsible. Pleural effusions resulting from simultaneous involvement of the membranes by two different pathologic processes are unusual.
文摘Background: Diaphragm surgery is common with advanced ovarian malignancies. The purpose of this study is to determine associated factors with the need for drainage of pleural effusion after diaphragm surgery. Methods and Materials: A retrospective chart review was undertaken in all women undergoing debulking surgery for stage IIIc/IV ovarian cancer from 2007-2009. Results: One hundred and eight patients were found to be eligible for the study, but 73 were the primary focus of this paper due to having undergone debulking surgery, including diaphragmatic surgery, from 2007-2009. All 73 had ablation with the argon beam coagulator, 7 had a full thickness resection, and 7 had extensive peritoneal peel. Five patients had preoperative effusions. Only 7 patients required chest drainage postoperatively. Pre-operative ascites correlated closely with postoperative effusion (p-value = 0.031) but not with drainage (p-value = 0.068). The mean age of patients requiring drainage was significantly older (73 years) than that of patients who did not require drainage (60 years) (p-value = 0.002). Conclusion: Older patients undergoing diaphragm surgery are more likely to require chest tube or thoracentesis due to concurrent symptoms. Pre-operative ascites correlates closely with the development of postoperative effusion after diaphragm surgery.
文摘Objective:To evaluate the diagnostic value of endostatin(ES),vascular endothelial growth factor (VEGF) and careinoembryonie antigen(CEA) in both serum and pleural effusion of lung cancer patients.Methods:Levels of ES,VEGF and CEA in 52 malignant pleural effusion due to lung cancer and 50 patients with non-malignant disease were measured by using sandwich enzymelinked immunosorbent assay and microparticle enzyme immunoassay.Results:The ES.VEGF and CEA levels in pleural effusion and serum,and their ratio(F/S) were higher in lung cancer group than that in benign group,and the differences were statistically significant(P【0.05).The diagnostic efficiency of ES+VEGF for lung cancer was superior to either single detection.The diagnostic efficiency of ES+VEGK+CEA was superior to either ES+VEGF or ES+CEA.Conclusions: The results suggest that ES,VEGF and CEA might be useful in the differentiation between benign and malignant pleural effusion due to lung cancer.In comparison with either single determination of concentration in serum or pleural fluid,the couiljined detection of two or three markers is of important clinical significance in the diagnosis of lung cancer.
文摘BACKGROUND: Pleural effusion frequently complicates hepatectomy and multiple factors contribute to its development following hepatectomy for primary liver cancer. The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospec- tively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days 1 and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day 1 and ALT plus prealbumin on postoperative days 1 and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.
文摘Postoperative pleural effusion occurs frequently after hepatectomy. The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P【0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.
文摘The occurrence of pancreatic pleural effusion,secondary to an internal pancreatic fistula,is a rare clinical syndrome and diagnosis is often missed.The key to the diagnosis is a dramatically elevated pleural fluid amylase.This pancreatic pleural effusion is also called a pancreatic pleural fistula.It is characterized by profuse pleural fluid and has a tendency to recur.Here we report a case of delayed internal pancreatic fistula with pancreatic pleural effusion emerging after splenectomy.From the treatment of this case,we conclude that the symptoms and signs of a subphrenic effusion are often obscure;abdominal computed tomography may be required to look for occult,intra-abdominal infection;and active conservative treatment should be carried out in the early period of this complication to reduce the need for endoscopy or surgery.

文摘Background and Objective:Percutaneous ultrasound-guided thermal ablation is one of the major treatment methods for liver cancer.Tumor location close to the diaphragm or gastrointestinal tract was regarded as the treatment contraindication before due to poor visibility of the tumor or increased risk of thermal injury to the adjacent organs.This study used artificial pleural effusion or ascites to extend the indications of thermal ablation for liver cancer.Methods:Artificial pleural effusion (20 cases) or ascites (36 cases) was performed in 56 difficult cases of percutaneous thermal ablation for liver tumors.The technical success rates, the rate of approaching the procedure goal, complications, and local treatment response were assessed.Results:The technical success rates were 95%(19/20) for artificial pleural effusion and 100% (36/36) for artificial ascites, the achieve purpose rates were 100%(19/19) and 91.7% (33/36), the complete ablation rates were 84.2% (16/19) and 93.9% (31/33), respectively.Coughing, transient hematuria, and subcutaneous effusion were observed in 3 patients after the procedure of artificial pleural effusion, and hydrothorax in the right chest occurred in 1 patient during the artificial ascites process.Conclusions:Thermal ablation with the use of artificial pleural effusion or ascites is a safe and effective treatment for liver tumors, and the technique can widen the indications of thermal ablation for liver tumors.
文摘Back ground: Pleural effusion is a common clinical problem with different causes. Objective: To demonstrate clinical features and outcome of pleural effusion. Methods: Prospective descriptive study was conducted involving 110 patients with pleural effusion admitted to a resource limited hospital in Ethiopia. Results: Males and females were almost equally represented. Cough, fever and weight loss were prominent presenting symptoms accounting 90, 77.3 and 77.3 percent respectively. Right side effusion was the common presentation 50 (45.5%). Forty (37.4%) patients had HIV infection among 107 tested. Tuberculosis was the commonest cause 78 (70.9%) followed by parapneumonic effusion 36 (32.7%) and empyema 27 (24.5%). Malignant pleural effusion was detected only in one patient. Eighty one (73.6%) improved from their illness and 7 (6.4%) died. Lympocytic pleural effusion found to be associated with tuberculosis (OR = 3.942 (1.527 - 10.179), P = 0.005. There were no associations between HIV infection, anemia, elevated ESR and side of pleural effusion with tuberculosis. Conclusion: Tuberculosis was the leading cause of pleural effusion in our setup even though etiologic diagnosis was difficult. Strengthening the laboratory and pathology services in the area is strongly recommended.
文摘Introduction: The objective of this study was the comparison of the results of T-SPOT.TB using pleural effusion (PE) with those of IGRAs using peripheral blood (PB) or other diagnostic methods for the diagnosis of tuberculous (TB) pleurisy. Methods: We measured adenosine deaminase (ADA) in PE, QuantiFERON TB-Gold In-Tube (QFT), and T-SPOT.TB using PB, and T-SPOT.TB using PE. The definite group of TB pleurisy included 12 patients and other disease group 33 patients. Main find-ings: Sensitivity for QFT using PB was 83% and specificity was 85%, sensitivity for T-SPOT.TB using PB was 92% and specificity was 82%, while sensitivity for ADA in PE was 83% and specificity was 76%. When we adopted the same cut-off level of a positive response for T-SPOT.TB as PB using PE, sensitivity for T-SPOT.TB using PE was 100% and specificity was 82%, respectively. Although there were no significant differences among the four diagnostic methods, sensitivity for T-SPOT.TB using PE gave the most accurate diagnosis of TB-definite patients compared to ADA in PE or QFT using PB. Conclusions: If we performed T-SPOT.TB using a local specimen from the infection site, we could obtain a higher sensitivity than IGRAs using PB or ADA in PE and the numbers of ESAT-6 and CFP-10-positive SFCs were 3 to 5 fold higher in PEMCs than in PBMCs. T-SPOT.TB using PE may become a useful diagnostic method for TB pleurisy.
文摘Objective:To assess the efficacy of ADA isoenzyme estimation over that of total ADA level in pleural fluid and serum as a more efficient diagnostic indicator in tuberculous pleural effusions in high prevalence country like India.Methods:The efficacy was analysed in total thirty four patients of pleural effusions.Total ADA was estimated by Guitsi and Galanti Calorimetric method and ADA isoenzymes with and without EHNA[Erythro-9-（2- hydroxy-3-nonyl） adenine]a potent ADA<sub>1</sub> inhibitor using the same method.Results:The results demonstrated a statistically significant values of ADA<sub>2</sub> in serum（P【0.001）,pleural fluid（P = 0.000） and significant value for the ratio of pleural fluid ADA<sub>2</sub>/serum ADA2（P【0.001） and pleural fluid ADA/ADA(<sub>2</sub>（P【0. 005）.The sensitivity and specificity values of pleural fluid ADA|2 is 81.8%and 91.6%（cut off value 60 IU/L for Tuberculous effusions）,serum ADA<sub>2</sub> 95.4%and 66%（cut off value 70 IU/L for tuberculous effusions）. ADA2<sub> </sub>is an isoenzyme,which is significantly raised in tuberculous pleural effusions both in the serum and pleural fluid.Conclusion:Estimation of ADA isoenzymes is redundant as a diagnostic aid over total ADA estimation in view of the limited improvements both in specificity and sensitivity patterns and also in term of cost-benefit ratio.

文摘In order to investigate the clinical value of vascular endothelial growth factor(VEGF) combined with interferon-γ(IFN-γ) in diagnosing malignant pleural effusion and tuberculous pleural effusion,42 cases of malignant pleural effusion and 45 cases of tuberculous pleural effusion in Tongji Hospital,from March 2004 to May 2005,were included.The carcinoembryonic antigen(CEA),VEGF and IFN-γ levels of pleural effusion were detected by using ELISA,and adenosine deaminase(ADA) activity was determined by using enzyme kinetic analytical method.The sensitivity,specificity,accuracy and area under the curve(AUCROC) of CEA and VEGF,VEGF/IFN-γ ratio,ADA and IFN-γ were measured by receiver operating characteristic curve(ROC).The results showed that CEA,VEGF levels and VEGF/IFN-γ ratio were significantly higher and the ADA and IFN-γ levels were significantly lower in malignant group than those in tuberculous group(P<0.01).The sensitivity,specificity,accuracy and AUCROC of VEGF/IFN-γ ratio(88.7%,99.8%,94.4%,0.96 respectively) were higher than those of CEA(67.8%,96.1%,82.4%,0.78 respectively) and VEGF(81.5%,84.3%,82.9%,0.79 respectively).The sensitivity,specificity,accuracy and AUCROC of IFN-γ(85.7%,96.4%,90.9%,0.94 respectively) were higher than those of ADA(80.2%,87.6%,83.8%,0.81 respectively).It was concluded that VEGF/IFN-γ ratio and IFN-γ could be used as valuable parameters for the differential diagnosis of malignant pleural effusion and tuberculous pleural effusion.
文摘Differential diagnosis of pleural effusion is an important issue, since the treatment modalities and prognosis strictly depend on early and correct diagnosis of the underlying etiology. We assessed the efficacy of vascular endothelial growth factor (VEGF) in the differential diagnosis of patients with malignant and non-malignant pleural diseases. And also is assessed of the VEGF as a marker for success of chemical pleurodesis in malignant pleural effusion. Pleural effusions of 40 patients with a mean age of 55 (range, 26 to 78 years) were examined. A total of 20 patients had malignant pleural effusion;malignant mesothelioma (n=7), lung cancer (n=5) and metastatic malignancies (n=8). Twenty patients had benign pleural effusion;fibrinous pleuritis (n=6), tuberculosis (n=3) empyema (n=5), congestive heart failure (n=3), and acute pancreatitis (n=3). Definitive diagnosis was obtained in all cases with blind or open pleural biopsy, and cytological examination. VEGF levels were determined by enzyme-linked immunosorbent assay. The VEGF level of pleural effusion was comparably higher in the malignant group. The mean level of VEGF in patients with malignant pleural effusions (21.7 ± 1.8 ng/ml) was significantly (P <0.001) higher than that of (13.2 ± 1.5 ng/ml) non-malignant effusions. No significant difference was found regarding the VEGF levels and histological types in malignant pleural effusions. Negative correlation was observed between success rate of pleurodesis and VEGF level of pleural effusion (p= 0.015). The measurement of VEGF levels in pleural effusion may be useful to differentiate malignant from nonmalignant pleural effusions. VEGF level may also be an important prognostic marker for effective treatment of the patients who had malignant pleural effusions with pleurodesis. It is important issue in here whether VEGF could be useful in prognostication of outcome of chemical pleurodesis or not.

文摘BACKGROUND Pleural effusions occur for various reasons,and their diagnosis remains challenging despite the availability of different diagnostic modalities.Medical thoracoscopy(MT)can be used for both diagnostic and therapeutic purposes,especially in patients with undiagnosed pleural effusion.AIM To assess the diagnostic efficacy and safety of MT in patients with pleural effusion of different causes.METHODS Between January 1,2012 and April 30,2021,patients with pleural effusion underwent MT in the Department of Respiratory Medicine,The Second Affiliated Hospital of Xi’an Jiaotong University(Shaanxi,China).According to the discharge diagnosis,patients were divided into malignant pleural effusion(MPE),tuberculous pleural effusion(TBPE),and inflammatory pleural effusion(IPE)groups.General information,and tuberculosis-and effusion-related indices of the three groups were analyzed.The diagnostic yield,diagnostic accuracy,performance under thoracoscopy,and complications of patients were compared among the three groups.Then,the significant predictive factors for diagnosis between the MPE and TBPE groups were analyzed.RESULTS Of the 106 patients enrolled in this 10-year study,67 were male and 39 female,with mean age of 57.1±14.184 years.Among the 74 thoracoscopy-confirmed patients,41(38.7%)had MPE,21 had(19.8%)TBPE,and 32(30.2%)were undiagnosed.Overall diagnostic yield of MT was 69.8%(MPE:75.9%,TBPE:48.8%,and IPE:75.0%,with diagnostic accuracies of 100%,87.5%,and 75.0%,respectively).Under thoracoscopy,single or multiple pleural nodules were observed in 81.1%and pleural adhesions in 34.0%with pleural effusions.The most common complication was chest pain(41.5%),followed by chest tightness(11.3%)and fever(10.4%).Multivariate logistic regression analyses showed effusion appearance[odds ratio(OR):0.001,95%CI:0.000-0.204;P=0.010]and carcinoembryonic antigen(OR:0.243,95%CI:0.081-0.728;P=0.011)as significant for differentiating MPE and TBPE,with area under the receiver operating characteristic curve of 0.977(95%CI:0.953-1.000;P<0.001).CONCLUSION MT is an effective,safe,and minimally invasive procedure with high diagnostic yield for pleural effusion of different causes.
文摘Pleural effusion after hepatectomy is associated with significant morbidity and prolonged hospital stays.Several studies have addressed the risk factors for postoperative pleural effusion.However,there are no researches concerning the role of the initial 12-h operative fluid volume.The aim of this study was to evaluate whether the initial 12-h operative fluid volume during liver resection is an independent risk factor for pleural effusion after hepatectomy.In this study,we retrospectively analyzed clinical data of 470 patients consecutively undergoing elective hepatectomy between January 2011 and December 2012.We prospectively collected and retrospectively analyzed baseline and clinical data,including preoperative,intraoperative,and postoperative variables.Univariate and multivariate analyses were carried out to identify whether the initial 12-h operative fluid volume was an independent risk factor for pleural effusion after hepatectomy.The multivariate analysis identified 2 independent risk factors for pleural effusion:operative time [odds ratio(OR)=10.2] and initial 12-h operative fluid volume(OR=1.0003).Threshold effect analyses revealed that the initial 12 h operative fluid volume was positively correlated with the incidence of pleural effusion when the initial 12-h operative fluid volume exceeded 4636 m L.We conclude that the initial 12-h operative fluid volume during liver resection and operative time are independent risk factors for pleural effusion after hepatectomy.Perioperative intravenous fluids should be restricted properly.

文摘Objective To compare intra-pleural injection efficacy and safety between Endostar and bevacizumab combined with pemetrexed/cisplatin for the treatment of malignant pleural effusion in patients with epidermal growth factor receptor(EGFR)-/anaplastic lymphoma kinase(ALK)-lung adenocarcinoma. Methods Sixty-four pCVatients with EGFR-/ALK-lung adenocarcinoma with malignant pleural effusion(MPE) were admitted to the authors' hospital between January 2016 and June 2017. Patients were randomly divided into two groups: Endostar combined with pemetrexed/cisplatin(Endostar group); and bevacizumab plus pemetrexed/cisplatin(Bevacizumab group). They underwent thoracic puncture and catheterization, and MPE was drained as much as possible. Both groups were treated with pemetrexed 500 mg/m^2, intravenous drip(d1), cisplatin 37.5 mg/m^2 per time, intra-pleural injection(d1, d3). Patients in the Endostar group were treated with Endostar 30 mg per time, intra-pleural injection(d1, 3), and patients in the Bevacizumab group were treated with bevacizumab 5 mg/kg per time, intra-pleural injection(d1). Only one cycle of treatment was applied. MPE was extracted before treatment and on day 7 after treatment. The levels of vascular endothelial growth factor(VEGF) were determined using ELISA. Efficacy and side effects were evaluated according to the Response Evaluation Criteria in Solid Tumors(RECIST) version 1.1, and National Cancer Institute Common Terminology Criteria for Adverse Events(CTCAE) version 3.0 criteria. Results The objective response rates in the Endostar and Bevacizumab groups were 50.0% and 56.3%, respectively; there was no statistical difference between the groups(P > 0.05). After one cycle of treatment, the mean VEGF levels in MPE in both groups decreased significantly, and there was no significant difference in the degree of decline between the two groups(P > 0.05). In both groups, pre-treatment VEGF levels for patients achieving complete response were significantly higher than those for patients achieving stable disease + progressive disease(P < 0.05). No specific side effects were recorded. Conclusion Endostar and Bevacizumab demonstrated similar efficacy in controlling MPE in patients with EGFR-/ALK-lung adenocarcinoma through an anti-angiogenesis pathway, with tolerable side effects. The levels of VEGF in MPE could predict the efficacy of intra-pleural injection of anti-angiogenesis drugs.
