Abstract
Numerous intrapleural therapies have been adopted to treat a vast array of pleural diseases. The first intrapleural therapies proposed focused on the use of fibrinolytics and DNase to promote fluid drainage in empyema. Numerous case series and five randomized controlled trials have been published to determine the outcomes of fibrinolytics in empyema treatment. In the largest randomized trial, the use of streptokinase had no reduction in mortality, decortication rates or hospital days compared with placebo in the treatment of empyema. Criticism over study design and patient selection may have potentially affected the outcomes in this study. The development of dyspnoea is common in the setting of malignant pleural effusions. Pleural fluid evacuation followed by pleurodesis is often attempted. Numerous sclerosing agents have been studied, with talc emerging as the most effective agent. Small particle size of talc should be avoided because of increased systemic absorption potentiating toxicity, such as acute lung injury. Over the past several years, the use of chronic indwelling pleural catheters have emerged as the preferred modality in the treating a symptomatic malignant pleural effusion. For patients with malignant-related lung entrapment, pleurodesis often fails due to the presence of visceral pleural restriction; however, chronic indwelling pleural catheters are effective in palliation of dyspnoea. Finally, the use of staphylococcal superantigens has been proposed as a therapeutic model for the treatment of non-small lung cancer. Intrapleural instillation of staphylococcal superantigens increased median survival by 5 months in patients with non-small cell lung cancer with a malignant pleural effusion.

Abstract
BACKGROUND More than 30% of patients with pleural infection either die or require surgery. Drainage of infected fluid is key to successful treatment, but intrapleural fibrinolytic therapy did not improve outcomes in an earlier, large, randomized trial. METHODS We conducted a blinded, 2-by-2 factorial trial in which 210 patients with pleural infection were randomly assigned to receive one of four study treatments for 3 days: double placebo, intrapleural tissue plasminogen activator (t-PA) and DNase, t-PA and placebo, or DNase and placebo. The primary outcome was the change in pleural opacity, measured as the percentage of the hemithorax occupied by effusion, on chest radiography on day 7 as compared with day 1. Secondary outcomes included referral for surgery, duration of hospital stay, and adverse events. RESULTS The mean (±SD) change in pleural opacity was greater in the t-PA-DNase group than in the placebo group (-29.5±23.3% vs. -17.2±19.6%; difference, -7.9%; 95% confidence interval [CI], -13.4 to -2.4; P=0.005); the change observed with t-PA alone and with DNase alone (-17.2±24.3 and -14.7±16.4%, respectively) was not significantly different from that observed with placebo. The frequency of surgical referral at 3 months was lower in the t-PA-DNase group than in the placebo group (2 of 48 patients [4%] vs. 8 of 51 patients [16%]; odds ratio for surgical referral, 0.17; 95% CI, 0.03 to 0.87; P=0.03) but was greater in the DNase group (18 of 46 patients [39%]) than in the placebo group (odds ratio, 3.56; 95% CI, 1.30 to 9.75; P=0.01). Combined t-PA-DNase therapy was associated with a reduction in the hospital stay, as compared with placebo (difference, -6.7 days; 95% CI, -12.0 to -1.9; P=0.006); the hospital stay with either agent alone was not significantly different from that with placebo. The frequency of adverse events did not differ significantly among the groups. CONCLUSIONS Intrapleural t-PA-DNase therapy improved fluid drainage in patients with pleural infection and reduced the frequency of surgical referral and the duration of the hospital stay. Treatment with DNase alone or t-PA alone was ineffective.

Abstract
BACKGROUND To study the efficacy and complications of percutaneous small bore pigtail catheters for tube thoracostomy. METHODS 50 cases of pleural effusion requiring drainage were enrolled in the study. Pigtail catheters of the size 9 to 12 F were used. RESULTS The procedure was successful in 46/50 (92%) cases. Fibrinolytic therapy and pleurodesis was successful through these tubes. Complications included blockade in 4 (8%), small pneumothorax in 10 (20%) and chest pain at tube thoracostomy site requiring analgesics in 30 (60%). CONCLUSION Small bore pigtail catheters are safe, comfortable, cost effective and have few complications especially in loculated pleural effusions.

Abstract
Effective palliative treatment in malignant pleural effusion can only be carried out when the lung is fully expanded after drainage of effusion. We investigated the efficacy of intrapleural fibrinolytics for lysing fibrin deposits and improving lung reexpansion in patients with malignant pleural effusion. We randomly allocated 47 patients with malignant pleural effusion into 2 groups: a fibrinolytic group of 24 were given 3 cycles of 250,000 U intrapleural streptokinase; the control group of 23 received pleural drainage only. Pleurodesis with 5 mg of talc slurry was performed in all patients who had lung reexpansion after drainage. Patient characteristics, pleural drainage, lung expansion assessed by chest radiography, and pleurodesis outcomes were compared between the 2 groups. Patient characteristics were similar in both groups. Lung reexpansion was adequate for performing talc pleurodesis in 96% of patients in the fibrinolytic group and 74% in the control group. In the fibrinolytic group, the mean volume of daily pleural drainage before streptokinase administration was 425 mL, and it increased significantly to 737 mL after streptokinase infusion. Intrapleural administration of streptokinase is advisable for patients with malignant pleural effusion.

Abstract
OBJECTIVE To determine the comparative effectiveness of common pleural drainage procedures for treatment of pneumonia complicated by parapneumonic effusion (ie, complicated pneumonia). DESIGN Multicenter retrospective cohort study. SETTING Forty children's hospitals contributing data to the Pediatric Health Information System. PARTICIPANTS Children with complicated pneumonia requiring pleural drainage. MAIN EXPOSURES Initial drainage procedures were categorized as chest tube without fibrinolysis, chest tube with fibrinolysis, video-assisted thoracoscopic surgery (VATS), and thoracotomy. MAIN OUTCOME MEASURES Length of stay (LOS), additional drainage procedures, readmission within 14 days of discharge, and hospital costs. RESULTS Initial procedures among 3500 patients included chest tube without fibrinolysis (n = 1762), chest tube with fibrinolysis (n = 623), VATS (n = 408), and thoracotomy (n = 797). Median age was 4.1 years. Overall, 716 (20.5%) patients received an additional drainage procedure (range, 6.8-44.8% across individual hospitals). The median LOS was 10 days (range, 7-14 days across individual hospitals). The median readmission rate was 3.8% (range, 0.8%-33.3%). In multivariable analysis, differences in LOS by initial procedure type were not significant. Patients undergoing initial chest tube placement with or without fibrinolysis were more likely to require additional drainage procedures. However, initial chest tube without fibrinolysis was the least costly strategy. CONCLUSION There is variability in the treatment and outcomes of children with complicated pneumonia. Outcomes were similar in patients undergoing initial chest tube placement with or without fibrinolysis. Those undergoing VATS received fewer additional drainage procedures but had no differences in LOS compared with other strategies.

Abstract
BACKGROUND Pleural empyema is a serious condition with a considerable mortality rate and morbidity. This study evaluated the correlations between several potential prognostic factors (age, predisposing diseases, early drainage, insufficient initial antimicrobial therapy, thoracic surgical treatment, intrapleural fibrinolysis, and nosocomial status) and outcome. METHODS Danish patients with positive pleural cultures attending 3 hospitals over a 9-y period, were identified in the laboratory databases. Clinical details and outcome were evaluated retrospectively by audit of the medical records. RESULTS We included 158 patients in this study. The overall mortality was 27% and the median length of stay was 29 days. Mortality correlated independently with several factors: nosocomial infection (odds ratio (OR) 2.62, 95% confidence interval (CI) 1.71-4.16), predisposing conditions (OR 2.17, 95% CI 1.50-3.14), and also with the possibly interventional factors of sufficient initial antimicrobial therapy (OR 0.45, 95% CI 0.31-0.65), thoracic surgery treatment (OR 0.27, 95% CI 0.14-0.52) and local fibrinolytic therapy (OR 0.13, 95% CI 0.06-0.28). Delay in chest tube drainage more than 2 days was not independently correlated with mortality. The initial biochemical diagnostics of non-purulent pleural effusions (63%) did not follow the current international guidelines. CONCLUSION Factors correlating independently with survival included the possible interventional parameters of fibrinolytic therapy, insufficient initial antimicrobial therapy, and having thoracic surgery treatment.

Abstract
Empyema thoracis causes high mortality, and its incidence is increasing in both children and adults. Parapneumonic effusions (PPEs) develop in about one-half of patients hospitalized with pneumonia, and their presence increases mortality by about four-fold. PPEs can be divided into simple PPEs, complicated PPEs, and frank empyema. Two guideline statements on the management of PPEs in adults have been published by the British Thoracic Society (BTS) and the American College of Chest Physicians; a third guideline statement published by the BTS focused on management of PPEs in children. The two adult guideline statements recommend drainage of the pleural space in complicated PPEs and frank empyema. They also recommend the use of intrapleural fibrinolysis in those who do not show improvement. The pediatric guideline statement recommends adding intrapleural fibrinolysis to those treated by tube thoracostomy if they have loculated pleural space or thick pus. Published guideline statements on the management of complicated PPEs and empyema in adults and children recommend the use of intrapleural fibrinolysis in those who do not show improvement after pleural space drainage. However, published clinical trial reports on the use of intrapleural fibrinolysis for the treatment of pleural space sepsis suffer from major design and methodologic limitations. Nevertheless, published reports have shown that the use of intrapleural fibrinolysis does not reduce mortality in adults with parapneumonic effusions and empyema. However, intrapleural fibrinolysis enhances drainage of infected pleural fluid and may be used in patients with large collections of infected pleural fluid causing breathlessness or respiratory failure, but a proportion of these patients will ultimately need surgery for definite cure. Intrapleural streptokinase and urokinase seem to be equally efficacious in enhancing infected pleural fluid drainage in adults. In most of the published studies in adults, the use of intrapleural fibrinolysis was not associated with serious side effects. There is emerging evidence that the combination of intrapleural tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) is significantly superior to tPA or DNase alone or placebo in improving pleural fluid drainage in patients with pleural space infection. In children, intrapleural fibrinolysis has not been shown to reduce mortality, but has been shown to enhance drainage of the pleural space and was safe. In addition, two prospective, randomized trials have shown that intrapleural fibrinolysis is as effective as video-assisted thoracoscopic surgery for the treatment of childhood empyema and is a more cost-effective treatment and therefore should be the primary treatment of choice.

Abstract
We retrospectively analyzed the data of 119 patients who were treated for empyema thoracis from 1999 to 2007. There were 87 men with a mean age of 63.9 years (range, 19–79 years) and 32 women with a mean age 55.2 years (range, 26–78 years). The empyema was right-sided in 73 patients and left-sided in 46. The etiology was parapneumonic in 43.7% of cases, postoperative in 42.0%, posttraumatic in 11.8%, and due to other causes in 2.5%. Eight (6.7%) patients underwent surgery on admission because of unstable clinical status; all 8 survived. Fibrinolysis was used in 111 (93.3%) patients; of these, 88 (73.9%) were successfully treated by intrapleural urokinase instillation, and 23 (19.4%) failed treatment and underwent surgery. All 88 patients who had successful fibrinolytic therapy survived, they accounted for 1.8% of the morbidity. In the 23 patients who underwent surgery after failed treatment, there were 3 deaths, accounting for 2.7% overall mortality and 6.3% morbidity. Treating thoracic empyema in patients with significant comorbidities is challenging. Intrapleural urokinase administration might be beneficial in high-risk patients, but in those without significant comorbidities, early surgery may be considered.

Abstract
BACKGROUND New information is available on pleural diseases. The authors selected articles to make recommendations on diagnostic and treatment aspects of pleural diseases. MATERIALS AND METHODS Eleven articles published in the English language between 2004 and 2007 were chosen. The basis of selection of the articles was the impact on daily practice, change in prior thinking of a disease process or specific treatment modality, as well as proper design and execution of the study. 5-Amino-laevulinic acid with fluorescent light combined with white light may allow further diagnostic yield in undiagnosed pleural disease. FDG-PET may allow prognostication of patients with pleural tumors. Utilizing ultrasound by trained Emergency Department physicians is a rapid and effective technique to evaluate non-traumatic pleural effusions in symptomatic patients. Serum osteopontin levels may distinguish patients exposed to asbestos with benign disease from those with pleural mesothelioma. Administration of streptokinase in patients with empyema does not need for surgical drainage, length of hospital stay, or mortality as compared to conventional treatment with chest tube drainage and intravenous antibiotics. Silver nitrate may be an alternative agent to talc for producing pleurodesis. Routine use of graded talc (50% particles greater than 25 microns) is recommended to reduce the morbidity associated with talc pleurodesis. Study design does not permit us to conclude that aspiration of spontaneous pneumothorax is as effective as chest tube drainage. Pleural catheter may prove to be an important palliative modality in treating debilitated patients or patients with trapped lung who show symptomatic improvement with drainage; however, at the present time, these catheters cannot be considered a first line treatment option for patients with malignant pleural effusion. One of the studies reviewed showed no significant difference in tract metastasis in patients with malignant mesothelioma undergoing an invasive pleural procedure with or without irradiation to the procedure site. However, the design of the trial does not allow us to make this conclusion at the present time.

Abstract
Epmyema thoracis is associated with high mortality ranging between 6% to 24%. The incidence of empyema is increasing in both children and adults; the cause of this surge is unknown. Most cases of empyema complicate community- or hospital-acquired pneumonia but a proportion results from iatrogenic causes or develops without pneumonia. Parapneumonic effusions (PPE) develop in about one half of the patients hospitalized with pneumonia and their presence cause a four-fold increase in mortality. Three stages in the natural course of empyema have long been described: the exudative, fibrinopurulent, and organizing phases. Clinically, PPE are classified as simple PPE, complicated PPE, and frank empyema. Simple PPE are transudates with a pH > 7.20 whereas complicated PPE are exudates with glucose level <2.2 mmol/l and pH < 7.20. Two guidelines statements on the management of PPE in adults have been published by the American College of Chest Physicians (ACCP) and the British Thoracic Society (BTS). Although they differ in their approach on how to manage PPE, they agree on drainage of the pleural space in complicated PPE and frank empyema. They also recommend the use of intrapleural fibrinolysis and surgical intervention in those who do not show improvement, but the level of evidence for the use of intrapleural fibrinolysis is not high highlighting the need for more research in this area. A recently published large randomized trial has shown no survival advantage with the use of intrapleural streptokinase in patients with pleural infection. However, streptokinase enhances drainage of infected pleural fluid and may still be used in patients with large collection of infected pleural fluid causing breathlessness or ventilatory failure. There is emerging evidence that the combination of intrapleural tPA/DNase is significantly superior to tPA or DNase alone, or placebo in improving pleural fluid drainage in patients with pleural space infection. A guideline statement on the management of PPE in children has been published by the BTS. It recommends the use of antibiotics in all patients with PPE in addition to either video-assisted thoracoscopic surgery (VATS) or tube thoracostomy and intrapleural fibrinolysis. Prospective randomized trials have shown that intrapleural fibrinolysis is as effective as VATS for the treatment of childhood empyema and is a more economic treatment and therefore, should be the primary treatment of choice.

Abstract
BACKGROUND The aim of this study was to improve the efficacy of treatment of complicated pleural effusions. METHODS In this prospective study, 76 consecutive children (average age 5.0 +/- 4.14 years) fulfilling the required classification criteria were duly treated with chest tube placement and divided into two groups depending on the presence of encapsulated or non-encapsulated effusions. Treatment of the former group was supplemented by intrapleural fibrinolysis. The effectiveness of treatment was assessed in terms of chest tube dwell-time and total length of hospitalization. Regression analysis was performed using independent factors that were associated with these dependent factors. Value differences for P < 0.05 were considered significant. RESULTS The ultrasound pleural distance and lactic-dehydrogenase content in the pleural fluid was significantly associated with the length of treatment (P < 0.01). Improved response to treatment, reduced duration of hospitalization (9.2 +/- 1.9 vs 11.5 +/- 0.9; P < 0.01) and tube dwell-time (7.6 +/- 1.3 vs 9.5 +/- 0.9; P < 0.01) was achieved in the intrapleural-fibrinolysis-treated group (n= 38) compared with controls (n= 38), with virtually the same total tube output (606.1 +/- 257.5 vs 673.1 +/- 347.4; P= 0.175). All patients were completely cured. Following 104 applications of the fibrinolytic agent there was one change in coagulation parameters: hypofibrinogenemia (in 1%). CONCLUSIONS The authors recommend intrapleural fibrinolysis as an effective and safe alternative treatment strategy in treating encapsulated pleural effusions in children.

Abstract
BACKGROUND Intrapleural urokinase has been shown to be effective in the treatment of pleural effusions in children. However, optimal dosing in children is debated. The aim of this study was to prospectively evaluate a specific pediatric protocol of intrapleural urokinase. METHODS All children admitted to a single institution over a 6-year period with a diagnosis of pleural empyema were managed with chest tube and fibrinolytics. Clinical data were collected prospectively. Urokinase (56,000 IU in 56 mL saline/m(2) body surface) was administered twice daily, and was continued until resolution of the effusion. Further operative treatment was considered if urokinase treatment was unsuccessful after >/=3 days. Results are shown as median values (interquartile range). RESULTS Forty-one consecutive children aged 4.4 (3.2-6.9) years were included in the study, and received 420,000 (280,000-750,000) IU of urokinase over 7 (4-8) days. Suction through the chest drain was applied for 8 (6-10) days, and IV antibiotics were discontinued after 12 (10-15) days from the start of intrapleural fibrinolytics. Four children (9.8%) required 5 additional operative procedures (3 thoracoscopic debridements and 2 minithoracotomic debridements). Patients were discharged after 13 (11-16) days from the beginning of intrapleural urokinase. No major side effects attributable to urokinase were observed. CONCLUSION Intrapleural instillation of urokinase according to a specific pediatric protocol results in a high success rate when applied as a primary treatment in children with pleural empyema. Administration of a size-adjusted dose of urokinase proved to be safe and could optimize drug utilization.

Abstract
Pleural infections represent an important group of disorders that is characterized by the invasion of pathogens into the pleural space and the potential for rapid progression to frank empyema. Previous epidemiologic studies have indicated that empyema is increasing in prevalence, which underscores the importance of urgent diagnosis and effective drainage to improve clinical outcomes. Unfortunately, limited evidence exists to guide clinicians in selecting the ideal drainage intervention for a specific patient because of the broad variation that exists in the intrapleural extent of infection, presence of locules, comorbid features, respiratory status, and virulence of the underlying pathogen. Moreover, many patients experience delays in both the recognition of infected pleural fluid and the initiation of appropriate measures to drain the pleural space. The present review provides an update on the pathogenesis and interventional therapy of pleural infections with an emphasis on the unique role of image-guided drainage with small-bore catheters.

Abstract
BACKGROUND Pleural empyema is a collection of pus between the lungs and the chest wall. There is debate about treatment options with the advent of both fibrinolytic enzymes to facilitate tube drainage and less invasive video-assisted thoracoscopic surgery (VATS). OBJECTIVES To determine which was more effective: surgical (using thoracoscopy or thoracotomy) or non-surgical techniques (thoracocentesis, chest tube drainage); and to establish whether there was an optimum time for intervention. SEARCH STRATEGY In this updated review we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2005, issue 3) which contains the Acute Respiratory Infections Group's specialized register; MEDLINE (January 2002 to July Week 4, 2005); and EMBASE (January 2001 to 3rd Quarter 2005). Bibliographies, reference lists of identified studies and review articles were handsearched. Personal communication with authors is ongoing. There were no language restrictions. SELECTION CRITERIA Randomised controlled trials (RCTs) of surgical techniques versus non-surgical approaches for treatment of pus in the pleural cavity in children and adults but not neonates. Studies of empyema associated with tuberculosis or malignancy were excluded. DATA COLLECTION AND ANALYSIS Trial quality was assessed using Jadad criteria (Jadad 1996). Authors were contacted for missing information. The primary outcomes were death or resolution of the empyema. Secondary outcomes addressed the length of time chest tubes were required, pain, hospital stay and any complications. MAIN RESULTS Only one small randomised study was identified. Some methodological quality considerations cast doubt on the validity of the study with regard to patient selection, unclear allocation concealment and outcome assessor blinding and it scored 'B' overall (Jadad score 3). When compared with chest tube drainage combined with streptokinase, video-assisted thoracoscopic surgery (VATS) had a significantly higher primary treatment success and patients spent less time in hospital. Each treatment group suffered one mortality. The latest search revealed no further published randomised studies but communication with authors revealed two ongoing studies comparing conventional chest tube drainage plus antibiotics with and without fibrinolytics with video-assisted thorascopic surgery (VATS). A small unpublished study is awaiting assessment that compared chest tube drainage and antibiotics with thoracoscopy or thoracotomy plus antibiotics. AUTHORS' CONCLUSIONS It seems that for large, loculated pleural empyemas VATS is superior to chest tube drainage in terms of duration of chest tubes in situ and length of hospital stay. However, there are questions about validity in the one study which met the inclusion criteria and the study has too few participants to draw conclusions. There are risks of complications (associated with all treatments) which may not be apparent with small numbers. Larger studies are needed.

Abstract
Intrapleural fibrinolytic therapy (IFT) provides clinical benefit in the treatment of complicated pleural parapneumonic effusion (CPE). Whether IFT influences the proinflammatory cytokines production and fibrinlytic activity is currently unclear. Therefore, we collected pleural effusion samples from CPE patients with IFT (study group) and patients without IFT (control group). A membrane human inflammatory cytokines array kit was used to compare the difference of targeted cytokine production between these two groups. Enzyme-linked immunosorbent assay (ELISA) methods were used for quantitative analysis of targeted cytokines and fibrinolytic enzymes. The results showed there were no significant differences between the study (n = 16) and control (n = 14) groups in patients' demographic data. After fibrinolytic therapy, the patients in the study group had significant lower plasminogen activator inhibitor (PAI) level (732.36+/-254.09 ng/mL vs 1,509.36+/-1,340.11 ng/mL, p<0.05) and higher urokinase plasminogen activator (u-PA) level (75.56+/-41.70 ng/mL vs 6.87+/-5.07 ng/mL, p<0.05) than they did before treatment. Moreover, the tissue inhibitors of metalloproteinase-2 (TIMP-2) (1,560.03+/-403.49 pg/mL vs 3,686.45+/-1,263.83 pg/mL, p<0.05) and inflammatory chemokine, regulated on activation normal T-cell expressed and secreted/chemokine (C-C motif) ligand 5 (RANTES), (293.58+/-212.93 pg/mL vs 749.27+/-53.79 pg/mL, p<0.05), were also significantly lower in the study group after fibrinolytic therapy, but not in the control group. In conclusion, intrapleural fibrinolytic treatment with urokinase could enhance fibrinolytic activity and decrease TIMP-2 and RANTES production.

Abstract
The proenzyme single-chain urokinase plasminogen activator (scuPA) more effectively resolved intrapleural loculations in rabbits with tetracycline (TCN)-induced loculation than a range of clinical doses of two-chain uPA (Abbokinase) and demonstrated a trend toward greater efficacy than single-chain tPA (Activase) (Idell S et al., Exp Lung Res 33: 419, 2007.). scuPA more slowly generates durable intrapleural fibrinolytic activity than Abbokinase or Activase, but the interactions of these agents with inhibitors in pleural fluids (PFs) have been poorly understood. PFs from rabbits with TCN-induced pleural injury treated with intrapleural scuPA, its inactive Ser195Ala mutant, Abbokinase, Activase, or vehicle, were analyzed to define the mechanism by which scuPA induces durable fibrinolysis. uPA activity was elevated in PFs of animals treated with scuPA, correlated with the ability to clear pleural loculations, and resisted (70-80%) inhibition by PAI-1. Alpha-macroglobulin (alphaM) but not urokinase receptor complexes immunoprecipitated from PFs of scuPA-treated rabbits retained uPA activity that resists PAI-1 and activates plasminogen. Conversely, little plasminogen activating or enzymatic activity resistant to PAI-1 was detectable in PFs of rabbits treated with Abbokinase or Activase. Consistent with these findings, PAI-1 interacts with scuPA much slower than with Activase or Abbokinase in vitro. An equilibrium between active and inactive scuPA (k(on) = 4.3 h(-1)) limits the rate of its inactivation by PAI-1, favoring formation of complexes with alphaM. These observations define a newly recognized mechanism that promotes durable intrapleural fibrinolysis via formation of alphaM/uPA complexes. These complexes promote uPA-mediated plasminogen activation in scuPA-treated rabbits with TCN-induced pleural injury.

Abstract
PURPOSE To assess the feasibility and effectiveness of intrapleural recombinant tissue-type plasminogen activator (r-tPA) in the treatment of loculated parapneumonic effusions (PPEs). MATERIALS AND METHODS A single-arm prospective study of 25 consecutive patients with loculated PPEs was analyzed. All patients received 6-mg doses of intrapleural r-tPA on a defined schedule via a thoracostomy tube. The volume of output from the tubes was recorded and analysis of the fluid composition performed. Follow-up was both clinical and radiographic, with all patients undergoing pre- and postprocedural computed tomography. RESULTS Eighteen of the 25 patients (72%) required no additional intervention and had a complete clinical and radiographic response with the fibrinolytic therapy. Seven patients (28%) were treated with video-assisted thoracoscopic surgery, but no patient required thoracotomy for total decortication. There were no hemorrhagic complications. CONCLUSIONS Intrapleural r-tPA is effective in the treatment of loculated PPEs. It can be performed safely and in some patients may avoid the need for additional surgical intervention.

Abstract
BACKGROUND Intrapleural recombinant tissue plasminogen activator (r-TPA) has been successfully evaluated in pediatric patients with complicated parapneumonic pleural effusion (CPE) and pleural empyema (PE). Yet, there is no data concerning r-TPA in adults with CPE/PE. The aim of our study was to investigate the efficacy and complications of r-TPA in adult patients with CPE/PE. METHODS Twenty consecutive patients (mean age 50+/-18.9 years) with pleural infection (14 CPE and 6 PE) were included. Chest tube was inserted under guidance of chest ultrasound and/or computed tomography. After failure of pleural fluid drainage, 25mg of r-TPA was administered intrapleurally in a single daily dose. The evaluation was made according to imaging and clinical status. RESULTS The mean volume of fluid increased significantly after r-TPA administration (p<0.0001). White blood cells count (WBC) and C-reactive protein (CRP) were significantly improved after r-TPA instillations (both p<0.0001). Significant clinical and imaging improvement was noted in all but one patient after r-TPA administration (overall p<0.0001). Complications observed were mild: pain in 4 (25%) and local bleeding in 3 (15%) patients. The median number of r-TPA instillations was 3 (range 2-5). CONCLUSION Intrapleural instillation of r-TPA at a dose of 25 mg is a well-tolerated and effective treatment in 95% of our adult patients with CPE/PE.

Abstract
The administration of various fibrinolytic agents for the treatment of empyema has been reported in past studies. Most of the current literature has shown favorable outcomes in terms of increased tube drainage, improved chest radiography, and reduction in surgical intervention. However, a randomized controlled trial that compared streptokinase to placebo showed no significant reduction in mortality. To date, there have been no randomized controlled trials evaluating the safety, efficacy, and administration of recombinant tissue plasminogen activator for the treatment of empyema in the adult population. The authors report the use of a 10 mg daily dose of intrapleural recombinant tissue plasminogen activator for 6 days in a 57-year-old, white, male patient with empyema that was unresponsive to antibiotic therapy and chest tube drainage. They conclude that intrapleural administration of recombinant tissue plasminogen activator in conjunction with antibiotic therapy for the treatment of empyema in this patient resulted in increased chest tube drainage and provided complete resolution of all signs and symptoms of his infection.

Abstract
Our aim was to compare intrapleural streptokinase (SK) treatment and simple tube drainage in the treatment of children with complicated parapneumonic pleural effusion. A retrospective review of medical records included patient demographics, clinical presentation, biochemical and microbial studies of pleural effusion, radiographic evaluation of chest tube drainage, use of fibrinolytic agents and type of surgical intervention. During the 2.5-year period (1999-2002), 53 children (29 M, 24 F) with complicated parapneumonic effusions or empyema were identified. Closed tube drainage and antibiotic treatment were administered to patients with a diagnosis of complicated parapneumonic effusion (n = 24) until October 2000; after that time point, intrapleural streptokinase was added to this regimen (n = 29). The median age at the time of presentation was 2.5 years (range: 5 months-14.6 years). There were no significant differences in terms of clinical outcomes between the two groups. The average length of hospital stay was 19.1 +/- 5.5 and 21.9 +/- 11.2 days for the drainage and streptokinase groups, respectively; the time to afebrile state after admission was 5.8 +/- 4.1 and 7.6 +/- 7.5 days. The percentage of patients who eventually required surgical intervention was 8.3% for the drainage group and 20.6% for the streptokinase group. In conclusion, in the treatment of complicated parapneumonic effusions or empyema, the adjunctive treatment with intrapleural SK does not significantly reduce durations of fever, chest tube drainage and hospital stay, and the need for surgery, regardless of the stage of the disease, compared to simple closed tube drainage.

Abstract
BACKGROUND Pleural effusions and empyema may complicate lower respiratory tract infections. Treatment of these collections of pus includes surgical drainage and the use of intra-pleural fibrinolysis to break down fibrin bands that may cause loculation. OBJECTIVES To conduct a systematic review of the benefit of adding intrapleural fibrinolytic therapy to intercostal tube drainage in the treatment of complicated para pneumonic effusions and empyema to reduce mortality or the need for subsequent surgical debridement of the pleural space. SEARCH STRATEGY We searched the Cochrane Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. Trial authors were contacted for further information and details regarding the possibility of unpublished trials was requested. The most recent search was conducted in November 2006. SELECTION CRITERIA All studies in the review were Randomised Controlled Trials in adult patients with post-pneumonic empyema or complicated parapneumonic effusions who had not had prior surgical intervention or trauma. The intervention was an intrapleural fibrinolytic agent (streptokinase or urokinase) via an intercostal chest drain (ICD) versus control, or a comparison of the two agents. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data . Study authors were contacted for further information. MAIN RESULTS Seven studies met the eligibility criteria of the review, recruiting 761 participants. The only consistent end points in all trials were treatment failure, as gauged by the requirement for additional intervention including surgery or death. In studies where patients had either loculation and empyema, there was no significant difference in the risk of death with fibrinolytics (RR 1.08; 95% CI 0.69 to 1.68). When treatment failure was considered as surgical intervention, fibrinolytics reduced the risk of this outcome (RR 0.63; 95% CI 0.46 to 0.85), but there is discordance between earlier positive studies and the more recent negative study by Maskell. AUTHORS' CONCLUSIONS Intrapleural fibrinolytic therapy confers significant benefit in reducing the requirement for surgical intervention for patients in the early studies included in this review but not in the more recently published Maskell study. The reasons for this difference are uncertain. Separate subgroup analysis of proven loculated/septated effusions from the available data in our meta-analysis suggests a potential overall treatment benefit with fibrinolytics, but these results should be treated with caution as the data are incomplete and the benefit is not significant in the subgroup of high quality trials (Cochrane Grade A). Intrapleural fibrinolytics have not been shown to significantly increase adverse events, but the confidence interval is too wide to firmly exclude this possibility.

Abstract
PURPOSE To retrospectively determine the effectiveness of and risk for hemorrhage with intrapleural adjunctive tissue plasminogen activator (tPA) administered via chest tubes placed with imaging guidance. MATERIALS AND METHODS This HIPAA-compliant study was approved by the institutional review board of Massachusetts General Hospital, with informed consent waived. A retrospective review of 66 patients (age range, 1-95 years; mean age, 55 years; 44 male, 22 female) who received intrapleural tPA between 2000 and 2006 was performed. Overall effectiveness of tPA was defined as successful drainage without need for additional decortication or video-assisted thoracoscopic surgery. Primary and secondary effectiveness were defined as effectiveness after one and two cycles of tPA, respectively. Imaging findings and complications were recorded. Hemorrhagic complications were noted, and the Fisher exact test was used to show whether concurrent systemic anticoagulation increased bleeding risk. RESULTS Fifty-seven (86%) of 66 patients underwent complete drainage with tPA without further surgical procedures. Primary effectiveness was seen in 52 (87%) of 60 patients and secondary effectiveness was seen in five (83%) of six. Loculation of fluid was the most common finding in this selected cohort. Number of fluid pockets, pleural heterogeneity, and pleural thickness were not predictors of effectiveness. There were five major pleural hemorrhages in four patients across five tPA cycles. Hemorrhages occurred only in patients receiving therapeutic anticoagulation (four of 12) and in none of the other patients (P < .001). No hemorrhages occurred in the 38 patients receiving prophylactic anticoagulation. CONCLUSION Intrapleural tPA is effective in improving drainage of loculated effusions not drained with catheters alone; prophylactic systemic anticoagulation does not increase bleeding risk with intrapleural tPA, but therapeutic anticoagulation is associated with a significantly increased risk of pleural hemorrhage.

Abstract
BACKGROUND Posttraumatic empyema increases patient morbidity, mortality and length of hospital stay, and the cost of treatment. The aim of this study was to identify the risk factors for posttraumatic empyema and to review our treatment outcomes in patients with this condition. METHODS A total of 2261 patients who were admitted with thoracic traumas and underwent tube thoracostomy between January 1989 and January 2006 were investigated retrospectively. Posttraumatic empyema developed in 71 patients. Logistic regression was used to assess the association between potential risk factors for posttraumatic empyema. All values were expressed as the mean+/-S.D. RESULTS Eight hundred and thirty-six (37%) of the patients had penetrating type trauma, while 1425 (63%) had blunt type trauma. The rate of posttraumatic empyema development was 3.1% for all patients. Pulmonary contusion was seen in 221 (9.8%) patients and fractures of more than two ribs were seen in 191 (8.4%) patients. Tube thoracostomy placement was performed in the emergency room in 1728 (76.4%) patients, in the hospital ward in 197 (8.7%), in the intensive care unit in 182 (8.0%), and in the operating room in 154 (6.8%). The duration of tube thoracostomy was 6.11+/-2.99 (1-21) days. Retained haemothorax was seen in 175 (7.7%) patients. The mean lengths of hospital and intensive care unit stay were 6.42+/-3.45 and 2.36+/-2.66 days, respectively. The analysis showed that duration of tube thoracostomy (OR, 2.49, p<0.001), length of intensive care unit stay (OR, 4.21, p<0.001), and presence of contusion (OR, 3.06, p<0.001), retained haemothorax (OR, 5.55, p<0.001), and exploratory laparotomy (OR, 2.46, p<0.001) were independent predictors of posttraumatic empyema. The relative risk of posttraumatic empyema was higher than 1 for each of the following risk factors: penetrating trauma (OR, 1.59, p=0.055), associated injuries (OR, 1.12, p=0.628) and fractures of more than two ribs (OR, 1.60, p=0.197). CONCLUSION Prolonged duration of tube thoracostomy and length of intensive care unit stay, and the presence of contusion, laparotomy and retained haemothorax are independent predictors of posttraumatic empyema. Use of prophylactic antibiotics may be recommended in patients with these risk factors.

Abstract
We investigated the efficacy and safety of intrapleural instillation of recombinant tissue plasminogen activator (Alteplase) in 120 patients with complicated pleural effusion (CPE) or empyema. These 120 patients had failed simple chest tube placement and conventional medical treatment. The patients included 52 with empyema, 41 with CPE, 10 with hemothorax, and 17 with complicated malignant pleural effusions. A total of 345 doses of Alteplase were instilled intrapleurally in these patients, with doses ranging from 10 to 100 mg daily. Most patients required 3 to 4 doses of alteplase. After Alteplase therapy, complete resolution of CPE/empyema occurred in 102 patients (85%), partial resolution in 10 patients (8%), and failure to respond in 8 patients (7%). All patients who failed to respond to Alteplase treatment had either chronic empyema or empyema associated with lung abscesses. Adverse effects of Alteplase therapy were chest pain in 7 patients (6%) and bleeding at the chest tube site in 2 patients (2%).

Abstract
OBJECTIVE To present our method of treating pleural infection by using a combination of image-guided chest tube drainage and intrapleural fibrinolytics. PATIENTS AND METHODS We retrospectively reviewed the medical charts and radiographs of 30 consecutive patients with pleural infection who were seen at our institution from December 15, 1995, to July 1, 2006, 27 of whom received intrapleural urokinase or tissue-type plasminogen activator. End points were death, length of stay in the hospital, and percentage of patients who needed surgery. RESULTS Placement of chest tubes required image guidance 45.7% of the time. Three patients (10%; 95% confidence interval, 2.1%-26.5%) died of complications from pleural infection. None of the 30 patients (0%; 95% confidence interval, 0%-9.5%) required surgery for treatment of pleural infection. The median hospital length of stay was 11 days. CONCLUSIONS In the treatment of pleural infection, intrapleural urokinase or tissue-type plasminogen activator in combination with careful image-guided placement of chest tubes is highly effective in resolving the effusion and curing the infection.

Abstract
BACKGROUND The use of video-assisted thoracic surgery (VATS) in the treatment of pleural empyema has been proposed since the early 1990s, but among surgeons, its use varies considerably, and the results are discordant. This report aims to provide a retrospective assessment of the authors' experience and the literature on VATS in an effort to ascertain rational criteria for the use of this technique. METHODS Over a period of 12 years, a total of 120 cases of pleural empyema were recorded. The patients were assessed with chest x-ray, computed tomography, ultrasound, and thoracentesis. On the basis of clearly defined clinical and radiographic parameters, 38 patients underwent VATS immediately, whereas the remaining 82 were treated initially by means of tube thoracostomy. The latter was found to be sufficient for only 10 patients. Consequently, for the remaining 72 patients, it was decided to proceed also with VATS. RESULTS The procedure was performed completely by VATS in 101 patients (91.8%), whereas in 9 patients (8.2%) it was necessary to convert to thoracotomy. The postoperative course was uneventful for 98 of the 110 patients (89%), whereas the remaining 12 patients experienced complications, including one case of persistent empyema (0.9%) treated by thoracotomy. The mean chest tube duration was 6 days (range, 3-25 days). The mean postoperative hospital stay was 7.1 days (range, 5-17 days). Of the 80 patients completing a 6-month follow-up evaluation, the results were considered good for 72, moderately good for 8, and less than satisfactory for 2 patients. CONCLUSIONS In conclusion, the authors consider VATS to be the technique of first choice for the treatment of pleural empyema when the disease is advanced or tube thoracostomy fails. It provides excellent results with a low level of invasiveness and considerably reduces the need for thoracotomy. These results can be achieved with good videothoracoscopic experience and the use of a very precise technique.

Abstract
Empyema necessitans is a rare complication of pleural space infections and occurs when the infected fluid dissects spontaneously into the chest wall from the pleural space. This process may result from bronchopleural extension of a peripheral lung infection. These cases result from inadequate treatment of an empyema and usually occur after a necrotizing pneumonia or pulmonary abscess. We present two cases of empyema thoracic necessitans.

Abstract
OBJECTIVE AND BACKGROUND The aim of this study was to investigate the effectiveness of intrapleural heparin or heparin combined with human recombinant DNase in the treatment of empyema. METHODS Empyema was induced in rabbits with an intrapleural injection of 10(9)Pasteurella multicoda organisms in infusion agar via a surgically placed chest tube. Once empyema was verified, a blinded investigator administered drugs via the chest tube. There were three treatment groups each with six rabbits. One group was given 1000 IU heparin, a second group was given 1000 IU heparin plus 1 mg of human recombinant DNase via chest tube and the control group received saline. The rabbits received treatment every 12 h for a total of six treatments and the volume of each treatment was 3 mL. The animals were sacrificed at day 10 and the amount of empyema and pleural thickening was scored macroscopically on a scale of 0-6. RESULTS The total volume of pleural effusion aspirated was significantly higher in the heparin group (25.8+/-10.7 mL) compared with either saline (8+/-8.9) or heparin plus human recombinant DNase (6.8+/-6.1) groups (P=0.003). The mean empyema and pleural thickening scores did not differ significantly between the groups (P=0.8, P=0.5 respectively). A weak correlation was found between total volume of aspirated pleural fluid and pleural parameters of white blood cell counts and LDH levels (r=0.546 and P=0.02, r=0.631 and P=0.02 respectively). CONCLUSION The intrapleural administration of 1000 IU heparin alone or in combination with 1 mg of human recombinant DNase is no more effective than saline in the treatment of empyema in rabbits. Intrapleural heparin significantly increased the drainage of pleural fluid compared with the combination and saline group.

Abstract
AIM To assess the effect of intrapleural urokinase, vis-à-vis simple pleural drainage, on residual pleural thickening in a series of patients suffering from loculated tuberculous pleural effusion. PATIENTS AND METHOD Twenty-nine patients (21 males and 8 females) with loculated pleural effusion were studied. These patients were randomly allocated to one of two groups: one group received intrapleural urokinase (n=12) and the other was treated by simple drainage with suction (n=17). The urokinase (125,000 UI) was administered into the pleural cavity via an intrathoracic tube. This procedure was repeated every 12h until the quantity of pleural fluid obtained was less than 50 cm3, at which point the intrathoracic tube was removed. RESULTS In both groups, the biochemical analysis of the pleural fluid was an exudate and the fluid had a serous appearance. Pleural thickening when the drainage tube was removed was 8.09+/-3.36 mm for the group treated with urokinase, and 14.78+/-17.20mm (P>0.05) for the control group. Residual pleural thickening measured upon completion of medical treatment at 6 months was 1.45+/-0.89 mm for the group treated with urokinase and 7.47+/-10.95 mm for the control group (P<0.05). In the control group, only two patients presented over 10mm of residual pleural thickening. The mean quantity of fluid drained in the two groups was 1.487+/-711 ml for the patients with urokinase, and 795+/-519 ml for the control group (P<0.01). CONCLUSION Our study shows that patients with loculated tuberculous pleural effusion treated with urokinase suffered less from residual pleural thickening, as measured after six months, than those treated by simple drainage. It is therefore suggested that the administration of intrapleural urokinase is a safe and effective treatment for those patients who drain a larger quantity of pleural fluid.

Abstract
To evaluate the effective dose frequency (once daily vs. twice daily) of intrapleural urokinase treatment in children who required tube thoracostomy for drainage of a complicated parapneumonic effusion, we designed a randomised prospective study in a tertiary medical centre in Taiwan. From June 2002 to January 2005, 30 paediatric patients with complicated parapneumonic effusion who had received chest tube drainage were randomised 1 : 1 to the once-daily (urokinase 5000-6000 IU/kg/dose) or twice-daily (urokinase 2500-3000 IU/kg/dose) treatment. We compared clinical manifestations and outcomes in both groups. There were no differences in pleural effusion characteristics between the groups. Six patients had Streptococcus pneumoniae, one had Staphylococcus aureus, one had Group A Streptococcus, and 22 had unknown pathogens. There were no significant differences between the once- vs. twice-daily group in the amount of drained pleural fluid (564.9 +/- 422.1 ml vs. 560.5 +/- 198.6 ml, respectively), fever duration after chest tube insertion (4.3 +/- 3.2 days vs. 5.3 +/- 2.7 days), or total admission days (14.3 +/- 3.9 days vs. 14.6 +/- 3.0 days) (p > 0.05 for all). Only two patients (one in each group) required the surgery. Thus, we found that both once- and twice-daily administration of urokinase were similarly efficacious, and resulted in good clinical outcomes. Both obviated the need for surgery in most (93%) cases of pneumonia with complicated parapneumonic effusion in this series. A larger, multicentre study is necessary to verify our findings.

Abstract
Pneumonia with secondary pleural infection causes considerable morbidity and mortality. Intrapleural instillation of fibrinolytic agents to dissolve fibrinous adhesions is intended to improve pleural fluid drainage and prevent pleural loculations. In the last 20 years their application in the every day clinical practice has dragged much of attention and several studies have supported their use in the management of parapneumonic pleural effusions (PPE) and pleural empyema (PE). However, recent published data cast doubt on the effectiveness of intrapleural fibrinolytic agents in promoting drainage of infected pleural effusions. Pending future clinical trials, fibrinolytic therapy may be used selectively in patients who fail drainage with appropriately sized, image-guided chest tubes if reasons exist to delay or avoid definitive surgical drainage. The scope of this article is to systematically review evidence for the efficacy of intrapleural fibrinolytic therapy in the treatment of PPE and PE with emphasis on controlled trials and present some of the future perspectives.

Abstract
Pneumonia with complicated parapneumonic effusion and empyema is increasing in incidence and continues to be a source of morbidity in children seen in our institution. Current diagnostic modalities include chest radiographs and CT scanning with ultrasound being helpful in some situations. Exact management of empyema remains controversial. Although open thoracotomy drainage is well accepted in children, video-assisted thoracoscopic surgery (VATS) drainage has become more prevalent in the current era. Over the last 4 years, we have treated 58 children with intrapleural placement of pigtail catheters and administration fibrinolytics consisting of tissue plasminogen activator (tPA). Successful drainage and resolution of 54 of the 58 effusions was achieved with percutaneous methods alone. There was no mortality or 30-day recurrence. Mean hospital stay was 9.1 days (range 5 to 21) and mean chest catheter removal was 6 days post placement (range 1.5 to 20). Of the four patients that failed percutaneous tube therapy, 3 underwent video assisted thoracic surgery (VATS), and one had open thoracotomy with decortication. Based on our experience, tPA administered through a small bore chest tube for drainage of complicated parapneumonic effusions has become our standard practice. We reserve VATS for treatment failures and open thoracotomy and decortication for patients with VATS failure.

Abstract
We conducted a phase I study to determine a recommended dose (RD) of S-1 for chemo-radiotherapy consisting of S-1+ radiotherapy for T 2 N 0 larynx cancer. The method of administration used to assess the RD was irradiation with 2 Gy/day for 5 days a week until a total dose of 60 Gy, and concomitant administration of S-1 once a day for 2 weeks beginning on the day therapy was started followed by 2 weeks off the drug and 2 weeks on the drug with the dose escalating from S-1 60 mg/body/day (level 1) to 80 mg/body/day (level 2), and then to 100 mg/body/day (level 3). 18 patients were enrolled. 4 patients developed an adverse event of grade 3 radiation dermatitis which became a dose-limiting toxicity (DLT) at level 3. We then concluded that 100 mg/body/day was the maximum tolerated dose (MTD) of S-1 and decided that the RD of S-1 was 80 mg/body/day.

Abstract
PURPOSE OF REVIEW Pleural effusions, lung abscess and empyema remain a commonly encountered clinical problem and a significant source of morbidity. The aim of this review is to summarize recent developments with emphasis on controlled trials. RECENT FINDINGS There is wide variation in the management of infectious pleural effusions, partly because of the relative lack of randomized controlled trials. The recent MRC/BTS UK controlled trial of interapleural streptokinase for pleural infection assessed the efficacy of intrapleural streptokinase compared with placebo in complicated parapneumonic effusions. The study showed no difference in the primary end point, mortality, or in the need for surgery or length of the hospital stay among patients with pleural infection. The first large report published for over a decade has suggested that the bacteriological characteristics of lung abscess have changed. SUMMARY The major recent development in the management of pleural infections is the finding that we should dampen the ardor for the routine use of fibrinolytic agents in all patients with pleural infections. We strongly recommend the necessity for additional, well-designed trials to help determine optimal care for these seriously ill patients.

Abstract
Parapneumonic effusion is a common clinical problem, and those that go on to develop pleural infection have high morbidity and mortality. The process of pleural infection evolution involves changes in pleural physiology that are increasingly being elucidated and understood. The microbiology of pleural infection has changed over recent years, with clear differences emerging between hospital- and community-acquired infections. Using biochemical surrogates of infection, chest drainage can be undertaken rationally for those who do not respond to antibiotics alone. Recent data suggest that fibrinolytics do not influence outcomes in pleural infection. The optimal type and timing of surgery remain controversial.

Abstract
OBJECTIVES There have been no controlled studies to test the efficacy of tissue plasminogen activator (tPA) or recombinant human deoxyribonuclease (rhDNase) in the treatment of empyema. In vitro studies show that streptokinase without rhDNase does not liquefy empyemic material from rabbits. However, the combination of streptokinase and streptodornase and rhDNase have been shown to liquefy pus in vitro. The aim of this study was to determine if tPA or rhDNase, or a combination of the two, is more effective than saline solution in the treatment of empyema in rabbits. MATERIALS AND METHODS Empyema was induced in rabbits using 10(9) Pasteurella multicoda organisms in infusion agar injected via a surgically placed chest tube. Once empyema was verified, a blinded investigator administered one of four treatments via the chest tube: 3 mL of saline solution; 4 mg of alteplase (recombinant tPA); 1 mg of rhDNase; or 4 mg of alteplase and 1 mg of rhDNase. The rabbits received a treatment every 12 h following the initial for a total of six treatments. The animals were killed at day 10, and the degree of empyema and pleural peel was scored macroscopically on a scale of 0 to 4. RESULTS The combination group had a significantly lower mean empyema score (1.83 +/- 0.75) than did the saline solution group (3.86 +/- 0.38, p = 0.001), rhDNase group (3.17 +/- 0.75, p = 0.012), and alteplase group (3.71 +/- 0.49, p = 0.02) [+/- SD]. The total volume of pleural fluid was markedly higher in the alteplase and rhDNase combination group (142 +/- 79.1 mL) or the alteplase group (231 +/- 78.0 mL) compared to either the rhDNase group (0.8 +/- 1.6 mL) or the saline solution group (5.8 +/- 14.0 mL). CONCLUSION The combination of alteplase and rhDNase is more effective in the treatment of rabbit empyema than either agent alone. The intrapleural injection of alteplase alone or in combination with rhDNase leads to the production of large amounts of pleural fluid.

Abstract
BACKGROUND Randomized controlled trials have shown conflicting findings about the role of intrapleural fibrinolytic therapy for the treatment of empyema and complicated parapneumonic effusions in adult patients. OBJECTIVES To assess the clinical efficacy and summarize the current evidence of intrapleural fibrinolytic use in patients with empyema and complicated parapneumonic effusions in adult patients. METHODS We performed a meta-analysis of all properly randomized trials comparing intrapleural fibrinolytic agents with placebo in adult patients with empyema and complicated parapneumonic effusions. Outcome of primary interest was the reduction of death and surgical intervention. RESULTS We included five trials totaling 575 patients. The number of enrolled patients for each trial was small, except for the recent trial by Multicenter Intrapleural Sepsis Trial (MIST1) group. Compared with placebo, intrapleural fibrinolytic therapy was associated with a nonsignificant reduction in death and need for surgery (27.6% of the treatment group vs 32.8% of the control group; random-effects pooled risk ratio, 0.55; 95% confidence interval, 0.28 to 1.07; heterogeneity, p = 0.023). A separate analysis for outcomes on either death or need for surgery also showed nonsignificant results. CONCLUSION Our meta-analysis does not support the routine use of fibrinolytic therapy for all patients who require chest tube drainage for empyema or complicated parapneumonic effusions. However, there was significant heterogeneity of the treatment effects among the trials. Selected patients might benefit from the treatment.

Abstract
Patients with pleural infections have a high risk of morbidity and mortality with prolonged hospitalization. The best methods for treating pleural infections remain debatable. Although the increasing drainage volume effect of streptokinase adjunctive to chest-tube, is well known, its effect on clinical outcomes like duration of hospitalization and need for further surgery, remains controversial. The aim of this study was to analyze the etiological and microbiological factors for pleural infections, and assess the effect of streptokinase adjunctive to chest tube for clinical outcomes. Charts of patients with a chest disease department discharge diagnosis of complicated parapneumonic effusion or empyema were retrospectively reviewed. Of the 107 patients (85 male), the mean age was 47.9+/-17.1 years. The most frequently shown bacteriological agent was Staphylococcus aureus. Drainage with thoracentesis was used in 44 patients (group 1); chest tube was performed in 44 patients (group 2) and intrapleural streptokinase was given after chest tube insertion in 19 patients (group 3). Mean hospitalization time in group 1 was shorter than the other two groups (P<0.05), but there was no significant difference between group 2 and 3. Our mortality rate was 8.4%. Success rates were 95.4%, 65.9% and 78.5% in groups 1, 2, and 3, respectively (P>0.05). Intrapleural streptokinase is a safe procedure but it did not effect the duration of hospitalization, mortality and success rate. Mortality remains especially high in patients with concomitant disease.
