    Pleural effusions in tuberculosis are commonly seen in young adults as an immunological phenomenon occurring soon after primary infection. However, the epidemiology and demographics of tuberculous pleurisy are changing due to the impact of HIV co-infection and the increasing number of pleural effusions seen as part of re-activation disease. Pleural biopsy for histology and culture is the mainstay of diagnosis with closed needle biopsy adequate in the majority of cases. Techniques such as PCR of biopsy specimens and the role of pleural fluid ADA are still being evaluated as a diagnostic aid. Tuberculous empyema is less commonly seen in the western world and the diagnostic yield from pleural fluid here is greater than in "primary" effusions. Treatment with appropriate antituberculous chemotherapy is generally successful though there is currently insufficient evidence to recommend the routine use of corticosteroids in this condition.

    A 48-year-old woman with a 3-month history of back pain was admitted for further examination of multiple left pleural nodules. She had undergone bilateral breast augmentation with silicone implants 10 years previously. Nine years after the operation, both ruptured implants were removed, and autologous fat was injected. Computed tomography revealed multiple pleural nodules suggestive of malignant pleural mesothelioma. Thoracoscopic exploration revealed multiple pleural nodules with massive pleural adhesions. The nodules were filled with viscous liquid and were histologically determined to be siliconomas. Disseminated pleural siliconoma should be recognized as a late adverse event of silicone breast implantation. PMID:26652527

    Although it is curable, tuberculosis remains one of the most frequent causes of pleural effusions on a global scale, especially in developing countries. Tuberculous pleural effusion (TPE) is one of the most common forms of extrapulmonary tuberculosis. TPE usually presents as an acute illness with fever, cough and pleuritic chest pain. The pleural fluid is an exudate that usually has predominantly lymphocytes. The gold standard for the diagnosis of TPE remains the detection of Mycobacterium tuberculosis in pleural fluid, or pleural biopsy specimens, either by microscopy and/or culture, or the histological demonstration of caseating granulomas in the pleura along with acid fast bacilli, Although adenosine deaminase and interferon-γ in pleural fluid have been documented to be useful tests for the diagnosis of TPE. It can be accepted that in areas with high tuberculosis prevalence, the easiest way to establish the diagnosis of TPE in a patient with a lymphocytic pleural effusion is to generally demonstrate a adenosine deaminase level above 40 U/L. The recommended treatment for TPE is a regimen with isoniazid, rifampin, and pyrazinamide for two months followed by four months of two drugs, isoniazid and rifampin. PMID:27499981

  16. Diagnostic Tools of Pleural Effusion

    PubMed Central

    2014-01-01

    Pleural effusion is not a rare disease in Korea. The diagnosis of pleural effusion is very difficult, even though the patients often complain of typical symptoms indicating of pleural diseases. Pleural effusion is characterized by the pleural cavity filled with transudative or exudative pleural fluids, and it is developed by various etiologies. The presence of pleural effusion can be confirmed by radiological studies including simple chest radiography, ultrasonography, or computed tomography. Identifying the causes of pleural effusions by pleural fluid analysis is essential for proper treatments. This review article provides information on the diagnostic approaches of pleural effusions and further suggested ways to confirm their various etiologies, by using the most recent journals for references.

    Pleural effusion (PE) is a very uncommon manifestation of sarcoidosis. It is equally observed in men and women, can appear at any age and in all radiologic stages, though it is more common in stages i and ii. Effusions have usually a mild or medium size and mainly involve the right side. Various mechanisms can be implicated. PE will be a serous exudate if there is an increase in the capillary permeability due to direct involvement of the pleural membrane, a chylothorax if mediastinum lymph nodes compress the thoracic duct and/or the lymphatic drainage from the pleural cavity, an hemothorax if granuloma compress or invade pleural small vessels or capillaries, and even a transudate if there is compression of the inferior vena cava, atelectasis due to complete bronchial obstruction or when the resolution of the PE is incomplete with chronic thickening of visceral pleura (trapped lung). It manifests biochemically as a pauci-cellular exudate with a predominance of lymphocytes, though there can be a preponderance of eosinophils or neutrophils. Protein concentrations are usually proportionately higher than lactate dehidrogenase, adenosine deaminase is normally low and it is possible to find increased levels of CA-125 in women. The tuberculin test is negative and pleural or lung biopsies yield the diagnosis by confirming the presence of non-caseating granulomata. These PE can have a favorable self-limited outcome, even though in most cases treatment with corticosteroids is needed, while surgery is required in a few cases. PMID:24486113

    Pleural plaques were found in 644 (6·6%) of 9,760 photofluorograms taken in 1965 in a region of Pelhřimov district; the incidence was highest in the age group 66-70 years. The advanced age of those affected may be explained by the greater frequency of the causative agent in the past. The disorder was known in Pelhřimov district as early as 1930; it was then thought to be posttuberculous. The past history of the cases was uninformative; as a rule, the only common previous disease was pleurisy with effusion, occurring in 9·7%. The general condition of those affected was excellent; only 8% were aware of the fact that pleural lesions were present. The disorder was found mainly in farmers, familial incidence was common, and if two generations of one family suffered from the condition, the older generation was affected in 100%. Pleural plaques consist morphologically of limited areas of hyalinized collagenous connective tissue with calcium salt deposits. Tubercle bacilli could not be cultivated from the lesions. Mineralological analysis showed no evidence of silicates in the pleural plaques and a normal content in the lungs. The aetiological factor responsible for the development of pleural plaques in Pelhřimov district is not known, but asbestos cannot be implicated. The unknown noxious agent is carried to the pleura by the lymph and blood stream. Pleural plaques are an endemic disorder. The traditional view that lesions are post-tuberculous appears, in the region submitted to this study, to be a possible explanation. Images PMID:5465601

  3. Pleural effusion in ARDS.

    2014-02-01

    Pleural effusion is a fluid collection within the pleural space and is a common finding in mechanically ventilated patients. It is frequently related to fluid overload, hyponcotic states, heart failure, and altered pleural pressure due to atelectasis or pneumonia. Recent literature has shown that its incidence within ARDS is increasing, even if, in most of cases, at least in the early phases, it seems of limited clinical relevance. Most of the knowledge of Pleural Effusion and of its interaction with lung/chest wall mechanics derives from a small number of experimental studies and from some clinical studies, in most of the cases performed with normal lung parenchyma. In ARDS, however, Pleural Effusion seems to have a little effect "per se" on tidal mechanics and oxygenation (increasing elastance and reducing PO2), that are already profoundly affected by the lung injury itself. To sum up all the observations, we can assume that Pleural Effusion alters regional transmural pressure, restricting more the inspiration phase, and creating an opening/closure effect that can be reverted by PEEP application in recruitable lungs. This restores volume and compliance only if the abdomen is normally expansible. Drainage of Pleural Effusion is frequently performed in ICU but the benefits and risks are not well established. Lung ultrasound is an effective technique with high sensitivity and specificity for both bedside diagnosis and drainage guidance. It may help to quantify and qualify the effusion and at the same time the grade of aeration of underling parenchyma. Aim of this review is to summarize the current evidence and opinions about the interaction between Pleural Effusion and positive pressure ventilation in the presence of ARDS, its impact on gas exchange and tidal mechanics, trying to figure out the best bedside management that is not available yet. The estimation of both lung and chest wall elastance may help in the clinical decision making whether to drain or not in

    Objectives. To study the diagnostic value of pleural fluid cholesterol in differentiating transudative and exudative pleural effusion. To compare pleural fluid cholesterol level for exudates with Light's criteria. Design. Cross sectional descriptive study. Settings. Medical wards of Tribhuvan University Teaching Hospital. Methods. Sixty two cases of pleural effusion with definite clinical diagnosis admitted in TUTH were taken and classified as transudates (19) and exudates (43). The parameters pleural fluid protein/serum protein ratio (pfP/sP), pleural fluid LDH/ serum LDH ratio, pleural fluid LDH (pfLDH) and pleural fluid cholesterol (pCHOL) were compared with clinical diagnosis with regard to their usefulness for distinguishing between pleural exudates and transudates. Results. The pCHOL values determined were 1.92 ± 0.75 for exudates, 0.53 ± 0.28 for transudates, the differences between the transudates and others are statistically significant (P < 0.0001). It is seen that pfP/sP ratio has a sensitivity of 81.4% and specificity of 82.6%; pfLDH/sLDH ratio has a sensitivity of 86% and specificity of 94.7% and pCHOL with sensitivity of 97.7% and specificity of 100% for differentiating exudative and transudative PE. Conclusion. The determination of pCHOL is of great value for distinguishing between pleural exudates and transudates and should be included in routine laboratory analysis of pleural effusion.

    Tuberculous pleural effusion (TBPE) is the most common form of extrapulmonary tuberculosis (TB) in Spain, and is one of the most frequent causes of pleural effusion. Although the incidence has steadily declined (4.8 cases/100,000population in 2009), the percentage of TBPE remains steady with respect to the total number of TB cases (14.3%-19.3%). Almost two thirds are men, more than 60% are aged between 15-44years, and it is more common in patients with human immunodeficiency virus. The pathogenesis is usually a delayed hypersensitivity reaction. Symptoms vary depending on the population (more acute in young people and more prolonged in the elderly). The effusion is almost invariably a unilateral exudate (according to Light's criteria), more often on the right side, and the tuberculin test is negative in one third of cases. There are limitations in making a definitive diagnosis, so various pleural fluid biomarkers have been used for this. The combination of adenosine deaminase and lymphocyte percentage may be useful in this respect. Treatment is the same as for any TB. The addition of corticosteroids is not advisable, and chest drainage could help to improve symptoms more rapidly in large effusions. PMID:24721286

    We report a case of delayed cholelithoptysis and pleural empyema caused by gallstone spillage at the time of laparoscopic cholecystecomy. An occult subphrenic abscess developed, and the patient became symptomatic only after trans-diaphragmatic penetration occurred. This resulted in expectoration of bile, gallstones, and pus. Spontaneous decompression of the empyema occurred because of a peritoneo-pleuro-bronchial fistula. This is the first case of such managed nonoperatively and provides support for the importance of intraoperative retrieval of spilled gallstones at the time of laparoscopic cholecystectomy.

    2016-09-01

    Malignant pleural mesotheliomas (MPM) are very aggressive tumors, which originate from the mesothelial cells of the pleural surface. The main risk factor associated with MPM is exposure to asbestos. The latency period between asbestos exposure and MPM can be 30-60 years. Clinical symptoms and signs are often nonspecifc. The diagnosis of MPM requires an adequate tissue specimen for pathological examination, and video assisted thoracoscopic surgey (VATS) is associated with the highest diagnostic yield. MPM are histologically classified into epitheloid, sacromatoid and biphasic (mixed) sub-types. Accurate staging with invasive tests, if needed, is an important step before an interdisciplinary team can decide on an optimal (multi-modal) treatment approach. A multi-modal treatment approach (surgery, radiation oncology and chemotherapy) is superior to all approaches relying only on a single modality, if the patient qualifies for it from an oncological and functional standpoint. The goal of the surgical therapy is to achieve macroscopic complete resection. There are two competing surgical approaches and philosophies: extrapleural pneumonectomy (EPP) and radical pleurectomy (RP). Over the last years a paradigm shift from EPP to RP occurred and RP is now often the preferred surgical option. PMID:27612329

    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

    Malignant pleural mesothelioma (MPM) is a deadly disease that occurs in 2,000 to 3,000 people each year in the United States. Although MPM is an extremely difficult disease to treat, with the median overall survival ranging between 9 and 17 months regardless of stage, there has been significant progress over the last few years that has reshaped the clinical landscape. This article will provide a comprehensive discussion of the latest developments in the treatment of MPM. We will provide an update of the major clinical trials that impact mesothelioma treatment in the resectable and unresectable settings, discuss the impact of novel therapeutics, and provide perspective on where the clinical research in mesothelioma is moving. In addition, there are controversial issues, such as the role of extrapleural pneumonectomy, adjuvant radiotherapy, and use of intensity-modulated radiotherapy versus hemithoracic therapy that will also be addressed in this manuscript.

  13. Pleural mesothelial cells in pleural and lung diseases

    PubMed Central

    Antony, Veena B.

    2015-01-01

    During development, the mesoderm maintains a complex relationship with the developing endoderm giving rise to the mature lung. Pleural mesothelial cells (PMCs) derived from the mesoderm play a key role during the development of the lung. The pleural mesothelium differentiates to give rise to the endothelium and smooth muscle cells via epithelial-to-mesenchymal transition (EMT). An aberrant recapitulation of such developmental pathways can play an important role in the pathogenesis of disease processes such as idiopathic pulmonary fibrosis (IPF). The PMC is the central component of the immune responses of the pleura. When exposed to noxious stimuli, it demonstrates innate immune responses such as Toll-like receptor (TLR) recognition of pathogen associated molecular patterns as well as causes the release of several cytokines to activate adaptive immune responses. Development of pleural effusions occurs due to an imbalance in the dynamic interaction between junctional proteins, n-cadherin and β-catenin, and phosphorylation of adherens junctions between PMCs, which is caused in part by vascular endothelial growth factor (VEGF) released by PMCs. PMCs play an important role in defense mechanisms against bacterial and mycobacterial pleural infections, and in pathogenesis of malignant pleural effusion, asbestos related pleural disease and malignant pleural mesothelioma. PMCs also play a key role in the resolution of inflammation, which can occur with or without fibrosis. Fibrosis occurs as a result of disordered fibrin turnover and due to the effects of cytokines such as transforming growth factor-β, platelet-derived growth factor (PDGF), and basic fibroblast growth factor; which are released by PMCs. Recent studies have demonstrated a role for PMCs in the pathogenesis of IPF suggesting their potential as a cellular biomarker of disease activity and as a possible therapeutic target. Pleural-based therapies targeting PMCs for treatment of IPF and other lung diseases need

    Fleury Feith, J; Jaurand, M-C

    2013-12-01

    It is now well established that some pleural diseases, pleural plaques and malignant mesothelioma are related to asbestos fibre exposure although the mechanism of action of asbestos fibres is not fully understood. The development of artificial mineral fibres and carbon nanotubes, which share some morphological characteristics similar to asbestos fibres, is a present concern in the context of pleural diseases. Pleural plaques develop only in the parietal pleura, and in the 1990s, clinical observations have shown that the early development of mesothelioma also occurred on the parietal pleura. The peculiarity of the parietal pleura in contrast to the visceral pleura is the presence of "stomas" which are communication holes between the pleural cavity and the parietal pleura lymphatics. Morphological observations by thoracoscopy and experimental studies have shown that inhaled fibres translocate to the pleural space and, in human, are present in the parietal pleura at specific anthracotic areas (blackspots). Fibres accumulate on the stomas, up to block and locally induce an inflammatory reaction with cytokines release, that can be the bed of mesothelioma. However, despite the experimental data and observations in human pathology, the mechanisms of fibre translocation into the pleura is not yet clearly established. PMID:24210155

    Pleural space masses and nodules are rarely described on computed tomography (CT) in veterinary medicine and have only been described in patients with neoplasia. Our purpose was to describe the CT findings and diagnoses in seven patients with pleural masses and nodules. Two patients had broad-based, plaque-like pleural masses, both of which were due to neoplasia (primary pleural carcinoma, metastatic thymoma). Two patients had well-defined pleural nodules and nodular pleural thickening, one of which had mesothelial hypertrophy, and another of which had metastatic hemangiosarcoma. Three patients had ill-defined pleural nodules to nodular pleural thickening, one of which had metastatic pulmonary carcinoma, while the other two had bacterial infection with mesothelial proliferation (n = 2), fibrinous pleuritis (n = 1), and severe mediastinal pleuritis/mediastinitis (n = 2). Five of the seven patients had focal, multifocal or diffuse smooth, and/or irregular pleural thickening. Five of seven patients had pleural effusion, and postcontrast CT was useful in several patients for delineating the pleural lesions from the effusion. All patients except one had additional lesions identified on CT besides those in the pleural space. CT is useful in identifying and characterizing pleural space lesions and could be used to guide further diagnostic procedures such as thoracoscopy or exploratory thoracotomy. Both neoplastic and nonneoplastic diseases should be considered in the differential diagnoses for pleural space masses and nodules found on CT. PMID:22092656

    Malignant mesothelioma is caused almost exclusively by occupational exposure to asbestos. During the past few years, however, increasing evidence has mounted that background exposure to asbestos could be sufficient to cause mesothelioma. Treatment of malignant mesothelioma remains a big problem. Some new approaches are on their way, and the most exciting ones are local immunotherapy in very early cases. Some success has been reported with local interferon treatment. As for treatment of metastatic pleural disease, the main purpose is symptomatic relief of dyspnea caused by fluid accumulation. The best way to achieve a lasting palliation is pleurodesis, and the most common way to do this, is by chemical means. The drug of choice in the United States has for many years been tetracycline, but since injectable tetracycline is no longer available, some substitute must be found. The substance that will "win" is not yet clear, but the two leading contestants are talc and doxycycline. Bleomycin also has its supporters, and a dark horse is quinacrine, which although not easily available in the United States, has been used in many European centers for decades. PMID:9363074

    We herein report an asymptomatic 65-year-old male with localized pleural amyloidosis mimicking malignant pleural mesothelioma. He had a history of exposure to asbestos and was admitted for investigation of an abnormal pleural thickness detected by chest radiography. Positron emission tomography showed elevation of standardized uptake value corresponding to the pleural thickness. Partial pleurectomy including the tumor was performed for the purpose of diagnosis and local disease control. The pathological examination showed that the tumor was pleural amyloidosis. The tumor was diagnosed as localized primary amyloidosis, because serum monoclonal protein concentration did not increase. Pleural amyloidosis should be considered as a differential diagnosis from pleural mesothelioma. PMID:26904248

    Involvement of pleura by sarcoidosis remains a rare manifestation and varies from pleural effusion, pneumothorax, pleural thickening, hydropneumothorax, trapped lung, hemothorax, or chylothorax. Sarcoid pleural effusions presenting as hemorrhagic effusions are even more rare. We report a case of active pulmonary sarcoidosis presenting as hemorrhagic pleural effusion requiring tissue diagnosis to rule out malignancy. The rarity of the presentation prompted us to report this case.

    Involvement of pleura by sarcoidosis remains a rare manifestation and varies from pleural effusion, pneumothorax, pleural thickening, hydropneumothorax, trapped lung, hemothorax, or chylothorax. Sarcoid pleural effusions presenting as hemorrhagic effusions are even more rare. We report a case of active pulmonary sarcoidosis presenting as hemorrhagic pleural effusion requiring tissue diagnosis to rule out malignancy. The rarity of the presentation prompted us to report this case. PMID:27625449

    Malignant mesothelioma is a tumour of serous surfaces mainly arising at the pleura or the peritoneum. The diagnosis encompasses multiple problems as there is no pathognomonic hallmark for the disease, there are multiple histological types and the differentiation from other tumours, such as adenocarcinoma or metastatic pleural disease, can represent quite a challenge. Usually a diagnosis of malignant mesothelioma carries a dismal prognosis with scarce therapeutical options.The present report concerns a patient with a diagnosis of malignant pleural mesothelioma with endobronchial extension. Biopsy specimens were obtained through fibreoptic bronchoscopy and blind needle pleural biopsy. The final diagnosis was only possible after careful histological evaluation with a combination of immunohistochemical markers. PMID:21686530

  2. Pleural controversies: indwelling pleural catheter vs. pleurodesis for malignant pleural effusions

    2015-01-01

    Malignant pleural effusions (MPE) are frequent consequences of malignant disease and significantly impair the quality of life (QoL) of patients. There are two main options for the palliation of MPE-related symptoms: obliterating the pleural space by pleurodesis to prevent further fluid reaccumulation, or chronically draining the pleural fluid with an indwelling pleural catheter (IPC). There is controversy as to which approach is superior each having advantages and drawbacks. Pleurodesis offers a higher chance of rapid resolution of the pleural effusion with an intervention that is time limited but at the expense of a more invasive procedure, the need for a hospital stay and a higher need for repeat procedures. IPC offers an outpatient solution which is less invasive but at the cost of prolonged catheter drainages and care in a significant portion of patients who will not achieve pleurodesis. Impact on QoL, symptom relief and costs do not appear to be significantly different between the two options. Treatment of MPE should be tailored to the patient’s functional status, comorbidities, prognosis and personal preferences as well as local expertise. Hybrid approaches using pleurodesis techniques and IPC concomitantly may come into play in the near future to further improve patient care. PMID:26150918

    Primary malignant myelomatous pleural effusion (PMMPE) occurs in less than 1% of patients with multiple myeloma and is diagnosed either by visualization of plasma cells on cytology or by positive flow cytometry. The presence of immature plasma cells characterized by high nucleus to cytoplasm ratio, visible nucleolus and presence of Mott cells and Russell bodies are independent poor prognostic factors. The clinician should differentiate PMMPE from secondary pleural effusion as it is associated with a significantly worse prognosis and poor overall survival. PMID:27525090

    Pleural tuberculosis is the first or second most common form of extrapulmonary tuberculosis as well as the main cause of pleural effusion in many countries. It is rare in young infants and is more common in children over 10 years of age. We report the case of a 19-month-old girl admitted for prolonged fever with unilateral pleural effusion. The mother reported a history of lymph node tuberculosis 6 years previously. Intravenous antibiotics with cefotaxime and vancomycin were started. Thoracocentesis yielded a serosanguinous exudate fluid with a lymphocyte predominance. The tuberculin skin test and PCR GeneXpert(©) on pleural fluid were negative. The initial outcome was favorable, but the chest X-rays 10 days after discharge showed bilateral pleural effusion. Pleural biopsy was proposed but the culture of pleural fluid was positive for Mycobacterium tuberculosis. The child was put under standard treatment for tuberculosis. The outcome was favorable.

    Summary Background We performed this observational prospective study to evaluate the results of the application of a diagnostic and therapeutic algorithm for complicated parapneumonic pleural effusion (CPPE) and pleural parapneumonic empyema (PPE). Material/Methods From 2001 to 2007, 210 patients with CPPE and PPE were confirmed through thoracocentesis and treated with pleural drainage tubes (PD), fibrinolytic treatment or surgical intervention (videothoracoscopy and posterolateral thoracotomy). Patients were divided into 3 groups: I (PD); II (PD and fibrinolytic treatment); IIIa (surgery after PD and fibrinolysis), and IIIb (direct surgery). The statistical study was done by variance analysis (ANOVA), χ 2 and Fisher exact test. Results The presence of alcohol or drug consumption, smoking and chronic obstructive pulmonary disease (COPD) were strongly associated with a great necessity for surgical treatment. The IIIa group was associated with increased drainage time, length of stay and complications. No mortality was observed. The selective use of PD and intrapleural fibrinolysis makes surgery unnecessary in more than 75% of cases. Conclusions The selective use of PD and fibrinolysis avoids surgery in more than 75% of cases. However, patients who require surgery have more complications, longer hospital stay, and more days on PD and they are more likely to require admittance to the Intensive Care Unit. PMID:22739734

    Mass miniature radiography in 1969 detected a high prevalence of pleural calcification in three villages in northwest Greece. In 1980 a survey of a 15% sample of the population over the age of 10 was carried out with a 80% response rate. Full-size radiographs, ventilatory capacity measurements, and a detailed questionnaire on respiratory symptoms, type of work, and residence were used. Independent classification of the 408 films by two readers using the ILO/UC scheme showed very few small opacities but a very high prevalence of pleural calcification first evident in young adults and rising to 70% in the elderly. The overall prevalence was 34.7% in men and 21.5% in women. A comparison with the 1969 survey showed a progression rate of 5% per annum. In neither sex was there a significant relation of pleural calcification to smoking, ventilatory capacity, nor type of work, though those classified as field croppers had a slightly higher prevalence. There was no obvious evidence of increased lung cancer or mesothelioma in the village. The agent responsible for this apparently benign condition was not identified.

    The burden of a number of pleural diseases continues to increase internationally. Although many pleural procedures have historically been the domain of interventional radiologists or thoracic surgeons, in recent years, there has been a marked expansion in the techniques available to the pulmonologist. This has been due in part to both technological advancements and a greater recognition that pleural disease is an important subspecialty of respiratory medicine. This article summarises the important literature relating to a number of advanced pleural interventions, including medical thoracoscopy, the insertion and use of indwelling pleural catheters, pleural manometry, point-of-care thoracic ultrasound, and image-guided closed pleural biopsy. We also aim to inform the reader regarding the latest updates to more established procedures such as chemical pleurodesis, thoracentesis and the management of chest drains, drawing on contemporary data from recent randomised trials. Finally, we shall look to explore the challenges faced by those practicing pleural medicine, especially relating to training, as well as possible future directions for the use and expansion of advanced medical interventions in pleural disease.

    Thoracic sonography is an important tool in diagnosis and assessment of pleural effusions and can provide valuable information about the characteristics of accumulated pleural fluid, in addition to improving the safety of thoracentesis. In addition to the 4 classic sonographic pleural effusion patterns (anechoic, complex nonseptate, complex septate, and homogeneously echogenic), an echogenic swirling pattern has been previously described, which was originally thought to be associated with malignant effusion. Two cases of pleural effusion with an echogenic swirling pattern are described below, illustrating that this sonographic finding can be seen in both exudative and transudative effusions.

    In the pleural empyema (PE) treatment, not depending on introduction of multiple operative procedures and the medicinal preparations application, some issues remain unsolved, including the infection agents verification, the most rapid bronchial fistula elimination and the lung volume restoration. The EP infection agents spectrum, their sensitivity to preparations were revealed, as well as the enhanced rate of the methicillin-resistant stamms (MRSA) and the microorganisms associations verification. A reduction of the infection agents sensitivity towards "simple" antibacterial preparations was established, so the physicians, treating PE, must prescribe "hard" antibiotics, what enhances its cost.

    Pleural fibrosis is defined as an excessive deposition of extracellular matrix (ECM) components that results in destruction of the normal pleural tissue architecture. It can result from diverse inflammatory conditions, especially tuberculous pleurisy. Pleural mesothelial cells (PMCs) play a pivotal role in pleural fibrosis. Calpain is a family of calcium-dependent endopeptidases, which plays an important role in ECM remodeling. However, the role of calpain in pleural fibrosis remains unknown. In the present study, we found that tuberculous pleural effusion (TPE) induced calpain activation in PMCs and that inhibition of calpain prevented TPE-induced collagen-I synthesis and cell proliferation of PMCs. Moreover, our data revealed that the levels of angiotensin (ANG)-converting enzyme (ACE) were significantly higher in pleural fluid of patients with TPE than those with malignant pleural effusion, and ACE-ANG II in TPE resulted in activation of calpain and subsequent triggering of the phosphatidylinositol 3-kinase (PI3K)/Akt/NF-κB signaling pathway in PMCs. Finally, calpain activation in PMCs and collagen depositions were confirmed in pleural biopsy specimens from patients with tuberculous pleurisy. Together, these studies demonstrated that calpain is activated by renin-angiotensin system in pleural fibrosis and mediates TPE-induced collagen-I synthesis and proliferation of PMCs via the PI3K/Akt/NF-κB signaling pathway. Calpain in PMCs might be a novel target for intervention in tuberculous pleural fibrosis. PMID:27261452

    In this study we investigate the diagnostic value of pleural fluid procalcitonin (PCT) in distinguishing infectious and noninfectious etiologies of pleural effusion. We reviewed the medical records of 75 hospitalized patients who underwent thoracentesis between 2011 and 2012. Data on pleural fluid lactate dehydrogenase (LDH), protein, albumin, cell count and differential, pH, Gram stain and culture, cytology, triglyceride, cholesterol, amylase, and PCT were collected. Data on serum LDH, protein, albumin, prothrombin time, normalized, and blood culture were also collected. Pleural effusions were classified into 2 groups, infectious and noninfectious. There were 18 infectious pleural effusions (IPE) and 57 noninfectious pleural effusions (NIPE). Median pleural fluid PCT was 1.088 ng/mL (0.312-2.940 ng/mL) in IPE and 0.123 ng/mL (0.05-0.263 ng/mL) in NIPE, with a P value < 0.0001. Pleural fluid PCT > 0.25 ng/mL had a sensitivity of 77.78% and specificity of 74.14% for diagnosing an IPE. A subgroup analysis of PCT in exudative infectious effusions versus exudative noninfectious malignant/paramalignant effusions showed higher levels in the former. PCT is a novel biomarker for diagnosing infectious pleural effusion, and it would be worthwhile to investigate the role of pleural PCT in assessing severity of illness, risk stratification, and antibiotic stewardship in hospitalized patients with pleural effusions.

    The hypersensitivity reactions induced by drugs, some widely used, like central nervous system medication, can have various presentations. The lung is a frequent target for such events. We present the case of 40-year-old male patient, non-smoker, with infant encephalopaty, seizures since age of 6 with polimorphic crisis (mainly absences), with anticonvulsivant treatment since 2011 (carbamazepine, sodium valproate, levetiracetam), with no respiratory medical history. Current symptoms started two weeks before, with chest pain, dry cough. He received no antibiotics. Chest X-ray and thoracic CT scan (27 June 2013) showed a left pleral effusion. Left exploratory thoracocentesis extracted 20 ml reddish pleural fluid: eosinophilic exsudate (60%) with normal adenosin deaminase. He also presents moderate blood eosinophilia (13.7%-1780/mm3). Pulmonary infarction with secondary pleurisy, thoracic trauma, acute pancreatitis with secondary pleurisy were excluded. No Loeffler transient infiltrates were documented, serology for Toxocara is IgG positive (historical) and not significant for current episode, no symptoms suggestive for toxocarosis (characteristic to young children, patient had no liver enlargement etc.), no hidatidosis or trichinelosis were found. As an exclusion diagnosis, a hypersensitivity reaction to anticonvulsivant medication was considered (mentioned in literature) carbamazepine and sodium valproate (even if medication was taken for a longer time), with blood and pleural eosinophilia. Together with the neurologist, the mentioned drugs were stopped and he was started on lamotrigine 2 tb/day and levetiracetam 1 tb/day, well tolerated, no absences were noticed. Total remission of blood eosinophilia and partial remission of pleural effusion were noticed. Subsequent follow-ups confirm favourable evolution, with healing of pleurisy and normal blood cell count, which are stable at 7 months after changing anticonvulsivant treatment. PMID:25241560

    In order to determine variables that correlate with malignant pleural effusion and mortality in patients with lymphoproliferative disorders and pleural effusion, a retrospective study was performed. Clinical data of hospitalized patients with a lymphoid malignancy and pleural effusion who underwent thoracentesis from January 1993 to December 2002 were collected. A logistic regression analysis was carried out to determine prognostic variables that predict malignant pleural effusion and hospital mortality. There were 86 patients who were admitted on 91 occasions. The median age was 70 years (range 4 - 92) and the male:female ratio was 44:42. Sixty-four patients (74%) had advanced disease, 43 (50%) had received prior chemotherapy and 9 (10%) were in remission. Of 91 cases of pleural effusions, 44 (48%) were bilateral, 80 (88%) were exudates and 48 (53%) were due to malignant involvement of pleura. In multivariate analysis, symptomatic pleural effusion (odds ratio 10.3, 95% confidence interval 1.7 - 98.3), pleural fluid mesothelial cell count < 5% (odds ratio 8.0, 95% confidence interval 1.4 - 58.2), pleural fluid:serum lactate dehydrogenase (LDH) > or =1 (odds ratio 6.4, 95% confidence interval 1.2 - 45.6) and pleural fluid lymphocyte percentage > or =50 (odds ratio 6.4, 95% confidence interval 1.2 - 50) were significantly correlated with malignant effusion. A secondary cancer (odds ratio 11.9, 95% confidence interval 2.3 - 88.8), pleural fluid:serum LDH > or =1 (odds ratio 10.9, 95% confidence interval 2.6 - 64.9), and pneumonia (odds ratio 6.4, 95% confidence interval 1.7 - 28.6) were significantly correlated with hospital mortality. In conclusion, malignant pleural effusion is the common etiology of pleural effusion in patients with lymphoid malignancy. Many clinical and cytochemical markers have discriminatory values in identifying malignant effusion. A high pleural fluid to serum LDH level correlates with malignant pleural involvement and hospital mortality. PMID

    A pleural effusion is an excessive accumulation of fluid in the pleural space. It can pose a diagnostic dilemma to the treating physician because it may be related to disorders of the lung or pleura, or to a systemic disorder. Patients most commonly present with dyspnea, initially on exertion, predominantly dry cough, and pleuritic chest pain. To treat pleural effusion appropriately, it is important to determine its etiology. However, the etiology of pleural effusion remains unclear in nearly 20% of cases. Thoracocentesis should be performed for new and unexplained pleural effusions. Laboratory testing helps to distinguish pleural fluid transudate from an exudate. The diagnostic evaluation of pleural effusion includes chemical and microbiological studies, as well as cytological analysis, which can provide further information about the etiology of the disease process. Immunohistochemistry provides increased diagnostic accuracy. Transudative effusions are usually managed by treating the underlying medical disorder. However, a large, refractory pleural effusion, whether a transudate or exudate, must be drained to provide symptomatic relief. Management of exudative effusion depends on the underlying etiology of the effusion. Malignant effusions are usually drained to palliate symptoms and may require pleurodesis to prevent recurrence. Pleural biopsy is recommended for evaluation and exclusion of various etiologies, such as tuberculosis or malignant disease. Percutaneous closed pleural biopsy is easiest to perform, the least expensive, with minimal complications, and should be used routinely. Empyemas need to be treated with appropriate antibiotics and intercostal drainage. Surgery may be needed in selected cases where drainage procedure fails to produce improvement or to restore lung function and for closure of bronchopleural fistula. PMID:27147861

    Mast cells (MCs) have been identified in various tumors; however, the role of these cells in tumorigenesis remains controversial. Here, we quantified MCs in human and murine malignant pleural effusions (MPEs) and evaluated the fate and function of these cells in MPE development. Evaluation of murine MPE-competent lung and colon adenocarcinomas revealed that these tumors actively attract and subsequently degranulate MCs in the pleural space by elaborating CCL2 and osteopontin. MCs were required for effusion development, as MPEs did not form in mice lacking MCs, and pleural infusion of MCs with MPE-incompetent cells promoted MPE formation. Once homed to the pleural space, MCs released tryptase AB1 and IL-1β, which in turn induced pleural vasculature leakiness and triggered NF-κB activation in pleural tumor cells, thereby fostering pleural fluid accumulation and tumor growth. Evaluation of human effusions revealed that MCs are elevated in MPEs compared with benign effusions. Moreover, MC abundance correlated with MPE formation in a human cancer cell–induced effusion model. Treatment of mice with the c-KIT inhibitor imatinib mesylate limited effusion precipitation by mouse and human adenocarcinoma cells. Together, the results of this study indicate that MCs are required for MPE formation and suggest that MC-dependent effusion formation is therapeutically addressable. PMID:25915587

    Pleural involvement in sarcoidosis is uncommon and appears in several forms. To document the incidence and characteristics of pleural effusion in sarcoidosis patients, a review of the cases diagnosed in our centre between January 2001 and December 2012 was carried out. One hundred and ninety-five patients with sarcoidosis were identified; three (two men and one woman) presented with unilateral pleural effusion (1.5%): one in the right side and two in the left. Two were in stageii and one was in stageiv. The pleural fluid of the two patients who underwent thoracocentesis was predominantly lymphocytic. One of these patients presented chylothorax and the other had high CA-125levels. In general, these effusions are lymphocyte-rich, paucicellular, serous exudates (sometimes chylothorax) and contain proportionally higher levels of protein than LDH. Most cases are treated with corticosteroids, although it may resolve spontaneously. PMID:24565689

    Extra-abdominal complications of pancreatitis such as pancreaticopleural fistulae are rare. A pancreaticopleural fistula occurs when inflammation of the pancreas and pancreatic ductal disruption lead to leakage of secretions through a fistulous tract into the thorax. The underlying aetiology in the majority of cases is alcohol-induced chronic pancreatitis. The diagnosis is often delayed given that the majority of patients present with pulmonary symptoms and frequently have large, persistent pleural effusions. The diagnosis is confirmed through imaging and the detection of significantly elevated amylase levels in the pleural exudate. Treatment options include somatostatin analogues, thoracocentesis, endoscopic retrograde cholangiopancreatography (ERCP) with pancreatic duct stenting, and surgery. The authors present a case of pancreatic pseudocyst pleural fistula in a woman with gallstone pancreatitis presenting with recurrent pneumonias and bilateral pleural effusions. PMID:27274876

From our experience we conclude that thoracoscopy, when porperly performed, is diagnostic in most pleural conditions. PMID:594934

    Pleural photodynamic therapy (PDT) has been used as an adjuvant treatment with lung-sparing surgical treatment for malignant pleural mesothelioma (MPM). In the current pleural PDT protocol, a moving fiber-based point source is used to deliver the light. The light fluences at multiple locations are monitored by several isotropic detectors placed in the pleural cavity. To improve the delivery of light fluence uniformity, an infrared (IR) navigation system is used to track the motion of the light source in real-time at a rate of 20 - 60 Hz. A treatment planning system uses the laser source positions obtained from the IR camera to calculate light fluence distribution to monitor the light dose uniformity on the surface of the pleural cavity. A novel reconstruction algorithm is used to determine the pleural cavity surface contour. A dual-correction method is used to match the calculated fluences at detector locations to the detector readings. Preliminary data from a phantom shows superior light uniformity using this method. Light fluence uniformity from patient treatments is also shown with and without the correction method.

    Pleural disease is common with a rising case frequency. Many of these patients will be symptomatic and require diagnostic and/or therapeutic procedures. Patients with pleural disease present to a number of different medical specialties, and an equally broad range of clinicians are therefore required to have practical knowledge of these procedures. There is often underestimation of the morbidity and mortality associated with pleural interventions, even those regarded as being relatively straightforward, with potentially significant implications for processes relating to patient safety and informed consent. The advent of thoracic ultrasound (TUS) has had a major influence on patient safety and the number of physicians with the necessary skill set to perform pleural procedures. As the variety and complexity of pleural interventions increases, there is increasing recognition that early specialist input can reduce the risk of complications and number of procedures a patient requires. This review looks at the means by which complications of pleural procedures arise, along with how they can be managed or ideally prevented. PMID:26150919

    There is no detailed information about benign asbestos pleural effusion (BAPE). The aim of the study was to clarify the clinical features of BAPE. The criteria of enrolled patients were as follows: (1) history of asbestos exposure; (2) presence of pleural effusion determined by chest X-ray, CT, and thoracentesis; and (3) the absence of other causes of effusion. Clinical information was retrospectively analysed and the radiological images were reviewed. There were 110 BAPE patients between 1991 and 2012. All were males and the median age at diagnosis was 74 years. The median duration of asbestos exposure and period of latency for disease onset of BAPE were 31 and 48 years, respectively. Mean values of hyaluronic acid, adenosine deaminase, and carcinoembryonic antigen in the pleural fluid were 39,840 ng/mL, 23.9 IU/L, and 1.8 ng/mL, respectively. Pleural plaques were detected in 98 cases (89.1%). Asbestosis was present in 6 (5.5%) cases, rounded atelectasis was detected in 41 (37.3%) cases, and diffuse pleural thickening (DPT) was detected in 30 (27.3%) cases. One case developed lung cancer (LC) before and after BAPE. None of the cases developed malignant pleural mesothelioma (MPM) during the follow-up. PMID:26689234

    Abstract To study the performance of serum and pleural lactate dehydrogenase (LDH) level in predicting survival in patients with adenocarcinoma lung presenting with malignant pleural effusions (MPE) at initial diagnosis. Retrospective cohort study of the patient hospitalized for adenocarcinoma lung with MPE in year 2012. Univariate analyses showed lower pleural fluid LDH 667 (313–967) versus 971 (214–3800), P = 0.04, female gender 9 (100%) versus 27 (41.5%), P = 0.009, never smoking status 9 (100%) versus 36 (55.3%), P = 0.009, and epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) therapy 8 (89%) versus 26 (40%), P = 0.009 to correlate with survival of more than 1.7 year versus less than 1.7 year. In multivariate analysis, low pleural fluid LDH and female gender maintained significance. The pleural LDH level of ≤1500 and >1500 U/L discriminated significantly (P = 0.009) between survival. High pleural LDH (>1500 IU/L) predicts shorter survival (less than a year) in patients with adenocarcinoma lung presenting with MPE at the time of initial diagnosis. This marker may be clinically applied for selecting therapeutic modality directed at prevention of reaccumulation of MPE. Patients with low pleural LDH may be considered suitable for measures that provide more sustained effect on prevention of reaccumulation such as chemical pleurodesis or tunneled pleural catheter.

    2015-06-01

    Undiagnosed pleural effusions present an increasing diagnostic burden upon healthcare providers internationally. The investigation of pleural effusions often requires the acquisition of tissue for histological analysis and diagnosis. Historically there were two options for tissue biopsy: a 'gold standard' surgical biopsy or a "blind" closed pleural biopsy. Over the last decade however, image-guided Tru-cut biopsies and local anaesthetic thoracoscopic (local anaesthetic thoracoscopy) biopsies have become more widespread. Image-guided techniques acquire samples under ultrasound (US) or computed tomography (CT) guidance whereas LAT involves the direct visualisation and biopsy of the pleura with pleuroscopy. Both techniques have been shown to be superior to 'blind' closed pleural biopsy for the diagnosis of pleural or metastatic malignancy. However, closed biopsy remains a viable method of investigation in areas of high incidence of tuberculosis (TB). Beyond this, each investigative technique has its own advantages and disadvantages. Image-guided biopsy is less invasive, usually carried out as an outpatient procedure, and enables tissue biopsy in frail patients and those with pleural thickening but no pleural fluid. Local anaesthetic thoracoscopy (LAT) provides diagnostic and therapeutic capabilities in one procedure. Large volume thoracentesis, multiple pleural biopsies and talc poudrage can be carried out in a single procedure. The overall diagnostic yield is similar for both techniques, although there are no large-scale direct comparisons. Both techniques share low complication rates. PMID:26150917

    2016-01-01

    Mesothelioma is a rare pulmonary malignancy commonly associated with asbestos exposure. Its presentation is insidious and non-specific, with complaints of chest pain, dyspnea and cough. Chest X-ray may demonstrate unilateral pleural effusion. CT and PET scans may highlight nodular pleural plaques. Diagnosis often times is difficult with negative imaging and negative pleural fluid studies. In rare cases, hydropneumothoraces may be seen. We report a case of malignant pleural mesothelioma presenting as recurrent hydropneumothorax with negative CT scan of the chest for pleural abnormalities and negative pleural fluid studies.

    Objective To compare the multidetector CT (MDCT) features of malignant pleural mesothelioma (MPM) and metastatic pleural disease (MPD). Materials and Methods The authors reviewed the MDCT images of 167 patients, 103 patients with MPM and 64 patients with MPD. All 167 cases were pathologically confirmed by sonography-guided needle biopsy of pleura, thoracoscopic pleural biopsy, or open thoracotomy. CT features were evaluated with respect to pleural effusion, pleural thickening, invasion of other organs, lung abnormality, lymphadenopathy, mediastinal shifting, thoracic volume decrease, asbestosis, and the presence of pleural plaque. Results Pleural thickening was the most common CT finding in MPM (96.1%) and MPD (93.8%). Circumferential pleural thickening (31.1% vs. 10.9%, odds ratio [OR] 3.670), thickening of fissural pleura (83.5% vs. 67.2%, OR 2.471), thickening of diaphragmatic pleura (90.3% vs. 73.4%, OR 3.364), pleural mass (38.8% vs. 23.4%, OR 2.074), pericardial involvement (56.3% vs. 20.3%, OR 5.056), and pleural plaque (66.0% vs. 21.9%, OR 6.939) were more frequently seen in MPM than in MPD. On the other hand, nodular pleural thickening (59.2% vs. 76.6%, OR 0.445), hilar lymph node metastasis (5.8% vs. 20.3%, OR 0.243), mediastinal lymph node metastasis (10.7% vs. 37.5%, OR 0.199), and hematogenous lung metastasis (9.7% vs. 29.2%, OR 0.261) were less frequent in MPM than in MPD. When we analyzed MPD from extrathoracic malignancy (EMPD) separately and compared them to MPM, circumferential pleural thickening, thickening of interlobar fissure, pericardial involvement and presence of pleural plaque were significant findings indicating MPM than EMPD. MPM had significantly lower occurrence of hematogenous lung metastasis, as compared with EMPD. Conclusion Awareness of frequent and infrequent CT findings could aid in distinguishing MPM from MPD.

    Pleural lipomas are benign tumours that develop at the expense of adipose tissues, and they never evolve towards liposarcoma. Located usually at the mediastinal, bronchial and pulmonary levels, a pleural situation is extremely rare. Chest X-rays usually detect them and computed tomography scans confirm the diagnosis. As complications occur, a wait-and-see policy is common. We report our pleural lipoma surgical exeresis experience since 1999. We have operated on five cases of pleural lipomas among nearly 1800 cases of thoracic exeresis: three male and two female patients, without obesity (in all cases, body mass index (BMI) < 28). The mean age was 54.6 years (range 35–72 years). Four patients were electively operated and one in emergency, three with video-assisted thoracic surgery (VATS) procedure and two with open chest surgery, without recurrent cases. Advancements in VATS have greatly reduced the morbidity rate of these benign tumours especially if exeresis is performed early on a small, uncomplicated adhesion-free tumour. On the other hand, the operation may be deleterious, complicated by the presence of a large lipoma or in a complicating situation. In our opinion, we should revise the wait-and-see policy when facing these lesions considering their evolutionary potential. We should advise VATS in pleural lipomas. PMID:22371386

    Objective Although tuberculous pleural effusion (TPE) is commonly characterized by lymphocytic predominance and high adenosine deaminase (ADA) levels, it may present with neutrophilic predominance or low ADA levels, which are more commonly found in parapneumonic effusion (PPE) or malignant pleural effusion (MPE), respectively. A few studies have observed that the atypical pleural fluid profiles of these cases of TPE may resolve at follow-up thoracentesis. However, these observations were incompletely analyzed and lacked comparison with proper control groups. Thus, limited data are available comparing the sequential pleural fluid changes between TPE and PPE or MPE with similar pleural fluid profiles. Methods TPE, PPE, and MPE patients who underwent sequential thoracentesis were retrospectively reviewed. The sequential changes in the pleural fluid profiles were compared between neutrophilic TPE and PPE, and lymphocytic TPE and MPE with low ADA levels. Results Twenty-three TPE patients (16 with neutrophilic exudates, seven with lymphocytic exudates), 72 cases of PPE with neutrophilic exudates, and 18 cases of MPE with lymphocytic exudates were included in the analysis. A sequential shift to lymphocytic exudates occurred significantly more often in TPE than in PPE cases. The initial and follow-up ADA levels in TPE cases with a lymphocytic shift were significantly higher than those in PPE cases with a lymphocytic shift. The ADA levels in the TPE cases with initial lymphocytic exudates and low ADA levels significantly increased at follow-up thoracentesis. For the TPE and MPE cases with initial lymphocytic exudates and ADA levels <40 U/L, the frequency of effusion with ADA levels ≥40 U/L at the second thoracentesis was significantly higher in the TPE cases. Conclusion Follow-up thoracentesis may provide useful information for clinical decision-making in suspected atypical TPE cases with neutrophilic exudates or low ADA levels. PMID:27374670

    Pleural effusion is a common problem dealt by most of the practicing clinicians. Some causes for pleural effusion are less often considered as a differential diagnosis owing to its rarity. Here we report a case of renal amyloidosis on alternate day haemodialysis for about two months time presenting with left sided pleural effusion. On evaluation this turned out to be a case of amyloidosis on thoracoscopic pleural biopsy suggesting the possibility of Primary systemic amyloidosis. PMID:26029558

The radiology report obtained prior to admission did not describe the location of the Infuse-a-Port catheter. After a bedside thoracentesis demonstrated results consistent with chemotherapy infusate in the pleural space, further review of the medical imaging demonstrated that the catheter was in the pleural space.

    Background Breast cancer is the second most common etiologic cause in malignant pleural effusions (MPE). The aim of this study was to investigate the efficacy of long term pleural catheters in inducing self sclerosis in pleural effusions of breast cancer patients. Methods In this study, 26 patients with breast cancer relapleural effusions that occurred between January 2011 and July 2013, who were considered not to undergo any other treatments and managed with prolonged pleural catheters (Jackson-Pratt silicone flat drain), were retrospectively analyzed. Thirty pleural catheters were inserted in 26 patients. All patients were female, mean age was 52 (range, 37-66) years old. Drainage over 1,500 mL per day was not allowed in order to avoid a lung edema. The catheters were removed in patients who had restoration of lung expansion and drainage under 50 mL/day. Results The histologic subtypes in pleural effusions were invasive ductal carcinoma in 18 patients, ductal carcinoma in situ in 4, invasive lobular carcinoma in 2, tubular carcinoma in 1, and medullary carcinoma in 1. Three of the 26 patients underwent bilateral catheter insertion, and one patient underwent a reinsertion of the catheter into the same hemithorax due to a recurrence. The catheters were retained for a mean period of 18 days (range, 11-38 days). In one patient with invasive ductal carcinoma and paramalignant pleural effusion (PMPE) (3.8%), a recurrent pleural effusion was seen 34 days after removal of the catheter. There were no complications. One patient died while the catheter was in place. Conclusions Prolonged catheters for the management of pleural effusions in selected patients have become more popular than other treatment alternatives due to a shorter length of stay and lower costs. We recommend the use of Jackson Pratt (JP) silicone flat drains which in our opinion provide effective pleurodesis in addition to easy application in recurrent effusions caused by breast cancer.

    Diaphragmatic hernias that are diagnosed in adulthood may be traumatic or congenital in nature. Therefore, respiratory specialists need to be aware of the presentation of patients with these conditions. In this report, we describe a case series of patients with congenital and traumatic diaphragmatic hernias and highlight a varied range of their presentations. Abnormalities were noted in the thorax on the chest radiographs, but it was unclear as to the nature of the anomaly. The findings on thoracic ultrasound conducted by a pulmonologist helped to direct appropriate investigations avoiding unnecessary interventions. Instead of pleural effusions, consolidation or collapse, thoracic computed tomography demonstrated diaphragmatic hernias which were managed either conservatively or by surgery. There is increasing evidence that pulmonary specialists should be trained in thoracic ultrasonography to identify pleural pathology as well as safely conducting pleural-based interventions.

    Carbimazole, an antithyroid drug, is associated with a significant number of side effects, but pleuropulmonary complications are rare. We report the case of a 42-year-old Caucasian man who developed dyspnoea secondary to bilateral exudative pleural effusions while on carbimazole therapy. Extensive investigations, including a vasculitic screen, ruled out other potential causes for this patient's clinical presentation. This patient's pleural effusions gradually resolved within a few months of stopping carbimazole therapy, suggesting a role for the latter in the aetiopathogenesis of his presentation. Clinicians should consider discontinuing treatment with carbimazole and introducing alternative antithyroid therapy in this setting, once other potential causes of a pleural effusion have been systematically ruled out.

    1971-01-01

    The incidence, morbid anatomy, histology, and relationship of hyaline pleural plaques to exposure to asbestos has been studied. Plaques were found in 12·3% of 334 hospital necropsies (in an urban population in Glasgow, 41 cases). In 85·3% (35 cases) asbestos bodies were found in the lungs. There is evidence of a dose-response relationship between the number of asbestos bodies found in the lungs and the presence of pleural plaques. The selective distribution of plaques within the pleural cavities suggests that mechanical factors play a part in their localization. Histological examination contributed little to understanding the mechanism of plaque formation; that asbestos bodies have been detected in only a few cases suggest that their presence in the parietal pleura is not essential to plaque formation. The suggested mechanisms of plaque formation are discussed. Images PMID:5556121

    The aims of this study were to evaluate whether a recently published study used to objectively monitor pleural fluid volumes in dogs could be successfully employed in cats and secondly to assess its accuracy. Eleven feline cadavers were selected. Using the trans-sternal view employed in dogs, linear measurements from the pleural surface of the midline of the sternebra at the centre of the heart to the furthest ventro-lateral point of both right and left lung edges were recorded. Isotonic saline was injected using ultrasound guidance into both right and left pleural spaces and the measurements were repeated using standard increments until 400 ml total volume was reached. The mean measurement increased in a linear relationship with the cube root of fluid volume for all cats individually. An equation was produced to predict the volume of fluid from the mean linear measurement for all cats combined: Volume=[-3.75+2.41(mean)](3)(P<0.001) but variability in the slope of the curve for individual cats limited the accuracy of the combined equation. Equations were derived to predict the constant and slope of the curve for individual cats using the thoracic measurements made, but the residual diagnostic graphs demonstrated considerable variability. As in dogs, good correlation was found between the ultrasonographic measurement and fluid volume within individual cats. An accurate equation to predict absolute pleural fluid volume was not identified. Further analysis with reference to thoracic measurements did not increase accuracy. In conclusion, this study does provide a method of estimating absolute pleural fluid volume in cats, which may be clinical useful for pleural fluid volume monitoring but this is yet to be validated in live cats.

    On a global scale, tuberculosis (TB) remains one of the most frequent causes of pleural effusions. Our understanding of the pathogenesis of the disease has evolved and what was once thought to be an effusion as a result of a pure delayed hypersensitivity reaction is now believed to be the consequence of direct infection of the pleural space with a cascade of events including an immunological response. Pulmonary involvement is more common than previously believed and induced sputum, which is grossly underutilised, can be diagnostic in approximately 50%. The gold standard for the diagnosis of tuberculous pleuritis remains the detection of Mycobacterium tuberculosis in pleural fluid, or pleural biopsy specimens, either by microscopy and/or culture, or the histological demonstration of caseating granulomas in the pleura along with acid fast bacilli (AFB). In high burden settings, however, the diagnosis is frequently inferred in patients who present with a lymphocytic predominant exudate and a high adenosine deaminase (ADA) level, which is a valuable adjunct in the diagnostic evaluation. ADA is generally readily accessible, and together with lymphocyte predominance justifies treatment initiation in patients with a high pre-test probability. Still, false-negative and false-positive results remain an issue. When adding closed pleural biopsy to ADA and lymphocyte count, diagnostic accuracy approaches that of thoracoscopy. The role of other biomarkers is less well described. Early pleural drainage may have a role in selected cases, but more research is required to validate its use and to define the subpopulation that may benefit from such interventions. PMID:26150911

We report a case of a young man with a history of asthma who presented with cough, left-sided pleuritic chest pain and was found to have lobar atelectasis and an eosinophilic, empyematous pleural effusion. Bronchoscopy and sputum cultures grew Aspergillus fumigatus, and testing confirmed strong allergic response to this mold, all consistent with a diagnosis of ABPA. This novel and unique presentation of ABPA expands on the differential diagnosis of eosinophilic pleural effusions. PMID:21311176

    A 34-year-old female presented with end-stage renal disease (ESRD) treated by peritoneal dialysis (CAPD) complained of a dry cough. Chest X-ray and chest computed tomography (CT) scan revealed massive right hydrothorax. Because the glucose concentration of pleural fluid was markedly high compared with that of serum, we performed isotope and contrast peritoneography. We used CT for localizing it. MRI was also trying to show transdiaphragmatic leakage in peritoneoflural fistula. Temporary discontinuation of CAPD, tetracycline instillation into the pleural space and surgical patch grafting of the diaphragmatic leak have all been described. A novel method may be video-assisted talc pleurodesis. PMID:22111056

    Iatrogenic pulmonary barotrauma and cerebral arterial gas embolism (CAGE) may complicate a variety of medical procedures, such as certain types of surgery, drug administration through thoracic drainage, pneumoperitoneum, cystoscopy, bronchoscopy, etc. Hyperbaric oxygen treatment following the guidelines for CAGE in diving is the treatment of choice. Pleural streptokinase instillation is a common treatment for parapneumonic pleural effusion and may lead to CAGE. We present such a complication in a 79-year-old woman with a left-sided empyema. Neurological recovery was reasonable, but a left hemiparesis persisted. Prompt treatment of CAGE is necessary to avoid permanent injury and severe disability. PMID:24510333

    Pleural effusion in the horse can be caused by diseases such as pneumonia, trauma, pulmonary abscesses and thoracic neoplasms. Besides clinical (auscultation, percussion) and radiographic diagnostic procedures, the ultrasonic examination represents a method that supplies detailed information on quantity and location of fluid in the pleural space. By means of ultrasonic examination the most favourable position for a thoracentesis can be determined. Control of thoracentesis' efficiency as well as exact supervision of the disease's course are made feasible by repeated sonographic examinations. PMID:2694447

    Lymphatic filariasis is one of the major public health problems across the globe. Clinical manifestations usually depend on the site of lymphatic involvement. A 21-year-old female resident of a non-endemic filarial region presented with axillary lymphadenopathy, bilateral pleural effusion, ascites and pedal oedema. Fine-needle aspiration cytology (FNAC) of axillary lymph nodes revealed microfilariae. On the administration of diethyl carbamazine, lymph nodes gradually disappeared, the patient improved symptomatically and the filarial antigen test after treatment was negative. We report this case of bilateral axillary lymphadenopathy with pleural effusion and ascites as a rare manifestation of filariasis. PMID:21914673

    Although during the last few years there have been several important changes in the diagnostic or therapeutic methods, pleural effusion is still one of the diseases that the respiratory specialist have to evaluate frequently. The aim of this paper is to update the knowledge about pleural effusions, rather than to review the causes of pleural diseases exhaustively. These recommendations have a longer extension for the subjects with a direct clinical usefulness, but a slight update of other pleural diseases has been also included. Among the main scientific advantages are included the thoracic ultrasonography, the intrapleural fibrinolytics, the pleurodesis agents, or the new pleural drainages techniques. PMID:24698396

    Closed pleural biopsy used to be a popular method of evaluation of pleural effusion. With the advent of thoracoscopy, this valuable method is being neglected. Studies have shown that closed pleural biopsy especially done with image guidance has high yield and low complication rate as compared to thoracoscopy. Given the ease of the procedure and the less cost involved, imaged guided closed pleural biopsy should be considered as the initial diagnostic step in undiagnosed pleural biopsy especially in developing countries with high prevalence of tuberculosis.

    Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Pleural involvement is relatively rare. Development of pleural effusion in sarcoidosis needs to be evaluated for other causes, especially tuberculosis in endemic countries. Sarcoid pleural effusion responds to systemic corticosteroids. We are presenting case of 42 year old male patient of sarcoidosis who developed massive pleural effusion while on treatment with steroids, which was attributed to disease per se. Sarcoidosis as a cause of massive pleural effusion has not been mentioned before in published literature. PMID:26744683

    Background Tuberculous pleural effusion (TPE) exhibits different characteristics according to pleural fluid cellular predominance or whether the pleural fluid is free-flowing or loculated. However, its categorization based on either of these factors alone may be insufficient to properly reflect the heterogeneous manifestation of TPE. We evaluated the characteristics of the four TPE groups classified according to cellular predominance and whether the fluid is free-flowing or loculated. Methods A cohort of 375 patients with TPE was retrospectively reviewed. Clinical, radiological, and laboratory findings were compared between neutrophilic and lymphocytic TPE, and between free-flowing and loculated effusion for both neutrophilic and lymphocytic TPE. Results Lymphocytic TPE and neutrophilic TPE were observed in 336 (90%) and 39 (10%) patients, respectively. Pleural fluid loculation was present in 36% and 31% of the patients in the lymphocytic and neutrophilic groups, respectively. A few parameters of the laboratory findings between neutrophilic and lymphocytic TPE patients showed significant differences. However, these significant differences were prominently observed when comparing free-flowing and loculated subgroups of the respective neutrophilic and lymphocytic groups. Pleural fluid pH, lactate dehydrogenase, and adenosine deaminase levels were significantly different among the four subgroups. The neutrophilic loculated subgroup exhibited the most intense pleural inflammation and the highest mycobacterial yields when compared to the other subgroups. However, the percentage of neutrophils in the pleural fluid was not positively associated with the probability of culture-positive effusion. Conclusions The heterogeneous manifestation of TPE would be better characterized by using a classification system based on combined pleural fluid cellular predominance and loculation, with the neutrophilic loculated subgroup contributing to most of the clinically significant

    Background. There are no available literatures on massive pleural effusions (MPE) in our country. Aim. To determine the aetiology of MPE and compare the mortality rate between malignant and nonmalignant MPE in adult Nigerians. Methods. A prospective study of all the patients diagnosed with nontraumatic pleural fluid collections for one year in two tertiary federal hospitals in Southern Nigeria. A total of 101 consecutive patients with pleural fluid collections were studied. Diagnoses were made by clinical features and laboratory and radiological investigations. Results. Forty-eight patients (47.5%) had MPE with a mean age of 43 years ± 14.04 and 35 were females. Thirty patients (62.5%) were diagnosed with nonmalignant conditions (21 from pulmonary tuberculosis (PTB) and 9 from other causes). Haemorrhagic pleural collections were from malignancy in 12 (30.8%) and from PTB in 6 (15.4%). Straw-coloured collections were from malignancy in 9 (23.1%), from PTB in 8 (20.1%), and from posttraumatic exudative effusion in 3 (7.7%). Compared with nonmalignant MPE, patients with malignant collections had higher mortality within 6 months (8/18 versus 0/30 with a P value of 0.000). Conclusion. The presentation of patients with nontraumatic haemorrhagic or straw-coloured MPE narrows the diagnosis to PTB and malignancy with MPE cases being a marker for short survival rate. PMID:27437443

    Uniform light fluence distribution for patients undergoing photodynamic therapy (PDT) is critical to ensure predictable PDT outcome. However, common practice uses a point source to deliver light to the pleural cavity. To improve the uniformity of light fluence rate distribution, we have developed a treatment planning system using an infrared camera to track the movement of the point source. This study examines the light fluence (rate) delivered to chest phantom to simulate a patient undergoing pleural PDT. Fluence rate (mW/cm2) and cumulative fluence (J/cm2) was monitored at 7 different sites during the entire light treatment delivery. Isotropic detectors were used for in-vivo light dosimetry. Light fluence rate in the pleural cavity is also calculated using the diffusion approximation with a finite-element model. We have established a correlation between the light fluence rate distribution and the light fluence rate measured on the selected points based on a spherical cavity model. Integrating sphere theory is used to aid the calculation of light fluence rate on the surface of the sphere as well as inside tissue assuming uniform optical properties. The resulting treatment planning tool can be valuable as a clinical guideline for future pleural PDT treatment.

    The therapeutic options available for the management of malignant pleural effusions associated with a restricting malignant cortex remain unsatisfactory. The efficacy of pleuroperitoneal shunts was evaluated in 16 patients with recurrent malignant effusions. There were no operative deaths; one patient died on the third postoperative day as a result of lymphangitis carcinomatosa. The median hospital stay was five (range 3-21) days. Palliation was obtained in all but one of the other 15 patients. There was no appreciable reaccumulation of pleural fluid as judged by radiography. Two patients developed occlusion of the shunt. In one case this was due to blood clots in the pleural catheter and necessitated insertion of a new shunt. The other shunt was removed because of obstructing infected fibrin debris, and a rib resection was performed. There were eight deaths related to the underlying malignancy after a mean interval of 7.3 (range 1.5-23) months. The other six patients are still alive, with a mean survival of 11.0 (range 5-20) months, and have achieved good symptomatic relief. The insertion of a pleuroperitoneal shunt can offer effective palliation for patients with recurrent malignant pleural effusions. Images PMID:1696401

    Pleural thickenings can be found in asbestos exposed patient's lung. Non-invasive diagnosis including CT imaging can detect aggressive malignant pleural mesothelioma in its early stage. In order to create a quantitative documentation of automatic detected pleural thickenings over time, the differences in volume and thickness of the detected thickenings have to be calculated. Physicians usually estimate the change of each thickening via visual comparison which provides neither quantitative nor qualitative measures. In this work, automatic spatiotemporal matching techniques of the detected pleural thickenings at two points of time based on the semi-automatic registration have been developed, implemented, and tested so that the same thickening can be compared fully automatically. As result, the application of the mapping technique using the principal components analysis turns out to be advantageous than the feature-based mapping using centroid and mean Hounsfield Units of each thickening, since the resulting sensitivity was improved to 98.46% from 42.19%, while the accuracy of feature-based mapping is only slightly higher (84.38% to 76.19%).

    Pleural thickenings can be caused by asbestos exposure and may evolve into malignant pleural mesothelioma. While an early diagnosis plays the key role to an early treatment, and therefore helping to reduce morbidity, the growth rate of a pleural thickening can be in turn essential evidence to an early diagnosis of the pleural mesothelioma. The detection of pleural thickenings is today done by a visual inspection of CT data, which is time-consuming and underlies the physician's subjective judgment. Computer-assisted diagnosis systems to automatically assess pleural mesothelioma have been reported worldwide. But in this paper, an image analysis pipeline to automatically detect pleural thickenings and measure their volume is described. We first delineate automatically the pleural contour in the CT images. An adaptive surface-base smoothing technique is then applied to the pleural contours to identify all potential thickenings. A following tissue-specific topology-oriented detection based on a probabilistic Hounsfield Unit model of pleural plaques specify then the genuine pleural thickenings among them. The assessment of the detected pleural thickenings is based on the volumetry of the 3D model, created by mesh construction algorithm followed by Laplace-Beltrami eigenfunction expansion surface smoothing technique. Finally, the spatiotemporal matching of pleural thickenings from consecutive CT data is carried out based on the semi-automatic lung registration towards the assessment of its growth rate. With these methods, a new computer-assisted diagnosis system is presented in order to assure a precise and reproducible assessment of pleural thickenings towards the diagnosis of the pleural mesothelioma in its early stage.

    INTRODUCTION: The performance of blind closed pleural biopsy (BCPB) in the study of pleural exudates is controversial. OBJECTIVE: To assess the diagnostic yield of BCPB in clinical practice and its role in the study of pleural exudates. METHODS: Data were retrospectively collected on all patients who underwent BCPB performed between January 1999 and December 2011. RESULTS: A total of 658 BCPBs were performed on 575 patients. Pleural tissue was obtained in 590 (89.7%) of the biopsies. A malignant pleural effusion was found in 35% of patients. The cytology and the BCPB were positive in 69.2% and 59.2% of the patients, respectively. Of the patients with negative cytology, 21 had a positive BCPB (diagnostic improvement, 15%), which would have avoided one pleuroscopy for every seven BCPBs that were performed. Of the 113 patients with a tuberculous effusion, granulomas were observed in 87 and the Lowenstein culture was positive in an additional 17 (sensitivity 92%). The overall sensitivity was 33.9%, with a specificity and positive predictive value of 100%, and a negative predictive value of 71%. Complications were recorded in 14.4% of patients (pneumothorax 9.4%; chest pain 5.6%; vasovagal reaction, 4.1%; biopsy of another organ 0.5%). CONCLUSIONS: BCPB still has a significant role in the study of a pleural exudate. If an image-guided technique is unavailable, it seems reasonable to perform BCPB before resorting to a pleuroscopy. These results support BCPB as a relatively safe technique. PMID:23951560

    The aim of this study was to explore the diagnostic value of IL-31 levels in the pleural fluid and plasma to differentially diagnose tuberculous and malignant pleural effusion. We enrolled 91 cases, including tuberculous pleural effusion (TPE, n = 50), malignant pleural effusion (MPE, n = 41), other cases including pneumonia with pleural fluid, pulmonary tuberculosis and healthy people as controls. Whole blood was stimulated with the M. tuberculosis–specific antigens and plasma was collected. The multiplex bead-based cytokine immunoassay was employed to measure the levels of various cytokines. IL-31 was found to be the most prominent cytokine (P < 0.0001), and with an optimal cut-off value of 67.5 pg/mL, the sensitivity and specificity for the diagnosis of TPE were 86% and 100%, respectively. Furthermore, the tuberculosis-specific IL-31 levels in the plasma of TPE patients were higher than that of MPE patients (P = 0.0002). At an optimal cut-off value of 23.9 pg/mL, the sensitivity and specificity for the diagnosis of TPE were 92.9% and 85.7%, respectively. Ultimately, the combination of pleural fluid with the plasma tuberculosis-specific IL-31 levels improved the sensitivity and specificity to 94.0% and 95.1%, respectively. Thus, we identified a novel biomarker for the diagnosis of TPE for clinical application. PMID:26864868

    Patient: Male, 77 Final Diagnosis: Pleural small cell carcinoma Symptoms: Chest pain • shortness of breath Medication: — Clinical Procedure: Thoracocentesis Specialty: Pulmonology Objective: Rare disease Background: Small cell lung carcinoma (SCLC) usually presents as lung or mediastinal lesions. It is very rare for SCLC to present primarily as an isolated pleural effusion with no lung or mediastinal lesions. Case Report: We report the case of a 77-year-old white male with a 60-pack year history of smoking, chronic obstructive pulmonary disease (stage IV), and asbestos exposure who presented with shortness of breath and left lateral chest pain for 7 days. On physical examination, he was very short of breath, with a prolonged expiratory phase on chest auscultation. Laboratory results were normal except for leukocytosis and chest radiograph revealing left-sided pleural effusion. Computerized tomography (CT) scanning of the chest with IV contrast showed left-sided pleural effusion without any lung or mediastinal lesions. Thoracentesis was performed and fluid was sent for analysis. Repeat CT chest/abdomen/pelvis, done immediately following thoracocentesis, did not show any masses or lymphadenopathy. Fluid analysis, including cytology and immunostain pattern, was consistent with small cell carcinoma. Conclusions: Small cell lung cancer presenting as an isolated pleural effusion is extremely rare. It requires close attention to cytology and immunohistochemistry of pleural fluid samples. It also has implications for management and should be managed as limited-stage SCLC. PMID:26714576

    The mechanism(s) by which chronic inhalation of indium phosphide (InP) particles causes pleural fibrosis is not known. Few studies of InP pleural toxicity have been conducted because of the challenges in conducting particulate inhalation exposures, and because the pleural lesions developed slowly over the 2-year inhalation study. The authors investigated whether InP (1 mg/kg) administered by a single oropharyngeal aspiration would cause pleural fibrosis in male B6C3F1 mice. By 28 days after treatment, protein and lactate dehydrogenase (LDH) were significantly increased in bronchoalveolar lavage fluid (BALF), but were unchanged in pleural lavage fluid (PLF). A pronounced pleural effusion characterized by significant increases in cytokines and a 3.7-fold increase in cell number was detected 28 days after InP treatment. Aspiration of soluble InCl3 caused a similar delayed pleural effusion; however, other soluble metals, insoluble particles, and fibers did not. The effusion caused by InP was accompanied by areas of pleural thickening and inflammation at day 28, and by pleural fibrosis at day 98. Aspiration of InP produced pleural fibrosis that was histologically similar to lesions caused by chronic inhalation exposure, and in a shorter time period. This oropharyngeal aspiration model was used to provide an initial characterization of the progression of pleural lesions caused by InP. PMID:19995279

    Diagnosis of pleural plaques (PPs) is commonly straightforward, especially when a typical appearance is observed in a context of previous asbestos exposure. Nevertheless, numerous causes of focal pleural thickening may be seen in routine practice. They may be related to normal structures, functional pleural thickening, previous tuberculosis, pleural metastasis, silicosis or other rarer conditions. An application of a rigorous technical approach as well as a familiarity with loco-regional anatomy and the knowledge of typical aspects of PP are required. Indeed, false-positive or false-negative results may engender psychological and medico-legal consequences or can delay diagnosis of malignant pleural involvement. Correct recognition of PPs is crucial, as they may also be an independent risk factor for mortality from lung cancer in asbestos-exposed workers particularly in either smokers or former/ex-smokers. Finally, the presence of PP(s) may help in considering asbestosis as a cause of interstitial lung disease predominating in the subpleural area of the lower lobes. The aim of this pictorial essay is to provide a brief reminder of the normal anatomy of the pleura and its surroundings as well as the various aspects of PPs. Afterwards, the common pitfalls encountered in PP diagnosis will be emphasized and practical clues to differentiate actual plaque and pseudoplaque will be concisely described. PMID:26539633

    Pleural spread is difficult to treat in malignancies, especially in lung cancer and thymoma. Monotherapy with surgery fails to have a better survival benefit than palliative chemotherapy, the currently accepted treatment. Photodynamic therapy utilizes a photosensitizer to target the tumor site, and the tumor is exposed to light after performing a pleurectomy and tumor resection. However, the benefits of this procedure to lung cancer or thymoma patients are unknown. We retrospectively reviewed the clinical characteristics and treatment outcomes of patients with lung cancer or thymoma with pleural seeding who underwent pleural photodynamic therapy and surgery between 2005 and 2013. Eighteen patients enrolled in this study. The mean patient age was 52.9 ± 12.2 years. Lung cancer was the inciting cancer of pleural dissemination in 10 patients (55.6%), and thymoma in 8 (44.4%). There was no procedure-related mortality. Using Kaplan-Meier survival analysis, the 3-year survival rate and the 5-year survival rate were 68.9% and 57.4%, respectively. We compared the PDT lung cancer patients with those receiving chemotherapy or target therapy (n = 51) and found that the PDT group had better survival than non-PDT patients (mean survival time: 39.0 versus 17.6 months; P = .047). With proper patient selection, radical surgical resection combined with intrapleural photodynamic therapy for pleural spread in patients with non-small cell lung cancer or thymoma is feasible and may provide a survival benefit.

    Background: The diagnostic approach to exudative pleural effusion remains an underappreciated aspect of modern thoracic medicine. 15-20% of the pleural effusions remain undiagnosed. The most efficient approach to pleural exudates remains uncertain and controversial particularly if acquisition of pleural tissue is required. The clinician needs to consider various factors when confronted with the choice between closed pleural biopsy (CPB) and thoracoscopy. Hence this study was planned to compare the diagnostic efficacy of CPB and Thoracoscopic pleural biopsy (TPB). Materials and Methods: This was a prospective interventional study in patients of exudative pleural effusion. CPB was performed by Cope's biopsy needle. Then inspection of the pleural cavity was performed by single port rigid thoracoscope (KARL, STORZ TELECAM DX II 20 2330 20) with viewing angle of zero (0) degrees and biopsy taken from the diseased or unhealthy parietal pleura. Accordingly we compared the results of CPB and TPB. Results: 46 Patients underwent this study. In all 46 patients both CPB and TPB were performed. TPB was diagnostic in 36 cases (78.2%) while CPB was diagnostic only in 10 cases i.e. 21.7%. 10 (21,7%) cases remained undiagnosed. On thoracoscopic examination 30 patients were having nodularity, 25 (54.3%) were having adhesions and 20 (43.5%) were having hyperemia. 79.3% of the patients with nodularity turned out to be malignant and 71.4% of patients with adhesions and hyperemia tubercular. Conclusions: TPB has much greater diagnostic efficacy than CPB. PMID:27169119

    A case of primary macroglobulinemia with pleural and gastric involvement was presented. A 48-year-old female was admitted with productive cough. On physical examination neither lymphoadenopathy nor hepatosplenomegaly were found. In addition, no bleeding tendency nor disturbance of the visual acuity were detected. Her chest roentgenogram showed a moderate amount of pleural effusion in the left pleural cavity without infiltration in the lung fields and no evidence of swollen hilar or mediastinal lymphnodes. A monoclonal M-band of to IgM-kappa type was observed in her serum and the pleural effusion. The diffuse ulcerative lesion in the gastric mucosa was detected by gastrofiberscopy. The lymphoid cells taken from the pleural effusion and the gastric mucosa stained positively with fluorescein-conjugated antiserum to u or the kappa chain. Pleural effusion and gastric infiltration of lymphoid cells improved remarkably following ACOP therapy. PMID:2113145

    Objective. To describe a patient with unilateral exudative pleural effusion that developed after commencement of carbimazole. Methods. We describe the presentation and clinical journey of an elderly woman who presented to the chest physicians initially with pleural effusion but was followed up by the endocrinology team. Result. The patient was a 77-year-old Caucasian woman who presented with symptoms of breathlessness and a confirmed unilateral pleural effusion while being on treatment for thyrotoxicosis. Her symptoms needed recurrent hospital admission for investigations and drainage, but no potential cause was identified after extensive investigations. A drug-induced exudative effusion consequent to carbimazole intake was diagnosed as discontinuation of the drug lead to complete resolution of the effusion with no recurrence. Conclusion. Physicians and Endocrinologist must bear in mind that this potentially rare complication of carbimazole while treating patients of thyrotoxicosis as appearance of similar features in their patients while being on carbimazole should lead to the discontinuation of the drug, and alternative treatment strategy should be considered.

    Extrapleural pneumonectomy was introduced in the 1940s for the treatment of extensive infections of the lung and pleural space. Over the past 20 years, the extrapleural pneumonectomy technique has been modified and applied to the treatment of locally advanced malignant pleural mesothelioma, achieving substantial reductions in mortality. The current mortality rate of 3.4% at the Brigham and Women's Hospital has permitted us to expand our use of this operation to treat locally advanced lung cancer and thymoma. The extrapleural pneumonectomy technique consists of five basic steps: (1) Incision and exposure of the parietal pleura: (2) Dissection of the tumor and parietal pleura from the chest wall, diaphragm, and mediastinum: (3) Division and control of the pulmonary vessels and bronchus followed by lymph node dissection: (4) En bloc resection of the lung, pleura, pericardium, and diaphragm; (5) Reconstruction of the diaphragm and pericardium. Extrapleural pneumonectomy is a complex and challenging operation. Accompanied by a 60% minor and major complication rate, it requires a unique management approach to achieve 3.4% mortality. Primary contributing factors to the reduction in mortality include a reduced operative time of 3 h, refinements in operative technique, and improved selection of patients. The technique discussed below is the culmination of 20 years' experience with malignant pleural mesothelioma at the Brigham and Women's Hospital/Dana Farber Cancer Institute, Boston, MA USA.

    Pleural infections have high morbidity and mortality, and their incidence in all age groups is growing worldwide. Not all infectious effusions are parapneumonic and, in such cases, the organisms found in the pleural space are not the same as those observed in lung parenchyma infections. The diagnostic difficulty lies in knowing whether an infectious effusion will evolve into a complicated effusion/empyema, as the diagnostic methods used for this purpose provide poor results. The mainstays of treatment are to establish an early diagnosis and to commence an antibiotic regimen and chest drain as soon as possible. This should preferably be carried out with fine tubes, due to certain morphological, bacteriological and biochemical characteristics of the pleural fluid. Fluid analysis, particularly pH, is the most reliable method for assessing evolution. In a subgroup of patients, fibrinolytics may help to improve recovery, and their combination with DNase has been found to obtain better results. If medical treatment fails and surgery is required, video-assisted thoracoscopic surgery (VATS) is, at least, comparable to decortication by thoracotomy, so should only undertaken if previous techniques have failed. Further clinical trials are needed to analyze factors that could affect the results obtained, in order to define new evidence-based diagnostic and therapeutic strategies that provide more effective, standardized management of this disease.

    There are three major challenges in the diagnosis of malignant pleural mesothelioma: mesothelioma must be distinguished from benign mesothelial hyperplasia; malignant mesothelioma (and its subtypes) must be distinguished from metastatic carcinoma; and invasion of structures adjacent to the pleura must be demonstrated. The basis for clarifying the first two aspects is determination of a panel of monoclonal antibodies with appropriate immunohistochemical evaluation performed by highly qualified experts. Clarification of the third aspect requires sufficiently abundant, deep biopsy material, for which thoracoscopy is the technique of choice. Video-assisted needle biopsy with real-time imaging can be of great assistance when there is diffuse nodal thickening and scant or absent effusion. Given the difficulties of reaching an early diagnosis, cure is not generally achieved with radical surgery (pleuropneumonectomy), so liberation of the tumor mass with pleurectomy/decortication combined with chemo- or radiation therapy (multimodal treatment) has been gaining followers in recent years. In cases in which surgery is not feasible, chemotherapy (a combination of pemetrexed and platinum-derived compounds, in most cases) with pleurodesis or a tunneled pleural drainage catheter, if control of pleural effusion is required, can be considered. Radiation therapy is reserved for treatment of pain associated with infiltration of the chest wall or any other neighboring structure. In any case, comprehensive support treatment for pain control in specialist units is essential: this acquires particular significance in this type of malignancy. PMID:25059587

    We assessed the utility of ultrasound to guide the selection of closed pleural biopsy technique and site and to assess the respective contributions of repeat thoracentesis and closed pleural biopsy in 100 consecutive patients with undiagnosed pleural exudates. Thoracentesis was more likely to be diagnostic in TB than malignancy (77.8% vs 31.0%, p<0.001). The addition of ultrasound-guided biopsy increased the combined yield for all diagnoses from 48.0% to 90.0% (p<0.001), for malignancy from 31.0% to 89.7% (p<0.001) and for TB from 77.8% to 88.9% (p=0.688). Our findings suggest that this minimally invasive approach has a high diagnostic yield. PMID:25997433

    Analysis of pleural fluid can have, on its own, a high diagnostic value. In addition to thoracocentesis, a diagnostic hypothesis based on medical history, physical examination, blood analysis and imaging tests, the diagnostic effectiveness will significantly increase in order to establish a definite or high probable diagnosis in a substantial number of patients. Differentiating transudates from exudates by the classical Light's criteria helps knowing the pathogenic mechanism resulting in pleural effusion, and it is also useful for differential diagnosis purposes. An increased N-terminal pro-brain natriuretic peptide, both in the fluid and in blood, in a due clinical context, is highly suggestive of heart failure. The presence of an increased inflammatory marker, such as C-reactive protein, together with the presence of over 50% of neutrophils is highly suggestive of parapneumonic pleural effusion. If, in these cases, the pH is<7.20, then the likelihood of complicated pleural effusion is high. There remains to be demonstrated the usefulness of other markers to differentiate complicated from uncomplicated effusions. An adenosine deaminase > 45 U/L and>50% lymphocytes is suggestive of tuberculosis. If a malignant effusion is suspected but the cytological result is negative, increased concentrations of some markers in the pleural fluid can yield high specificity values. Increased levels of mesothelin and fibruline-3 are suggestive of mesothelioma. Immunohistochemical studies can be useful to differentiate reactive mesothelial cells, mesothelioma and metastatic adenocarcinoma. An inadequate use of the information provided by the analysis of pleural fluid would results in a high rate of undiagnosed effusions, which is unacceptable in current clinical practice.

    Abstract The diagnosis of malignant pleural effusions may be challenging when cytological examination of aspirated pleural fluid is equivocal or noncontributory. The purpose of this study was to identify protein candidate biomarkers differentially expressed in the pleural fluid of patients with mesothelioma, lung adenocarcinoma, lymphoma, and tuberculosis (TB). A multiplex protein biochip comprising 120 biomarkers was used to determine the pleural fluid protein profile of 29 mesotheliomas, 29 lung adenocarcinomas, 12 lymphomas, and 35 tuberculosis. The relative abundance of these predetermined biomarkers among groups served to establish the differential diagnosis of: malignant versus benign (TB) effusions, lung adenocarcinoma versus mesothelioma, and lymphoma versus TB. The selected putative markers were validated using widely available commercial techniques in an independent sample of 102 patients. Significant differences were found in the protein expressions of metalloproteinase-9 (MMP-9), cathepsin-B, C-reactive protein, and chondroitin sulfate between malignant and TB effusions. When integrated into a scoring model, these proteins yielded 85% sensitivity, 100% specificity, and an area under the curve (AUC) of 0.98 for labeling malignancy in the verification sample. For lung adenocarcinoma–mesothelioma discrimination, combining CA19-9, CA15-3, and kallikrein-12 had maximal discriminatory capacity (65% sensitivity, 100% specificity, AUC 0.94); figures which also refer to the validation set. Last, cathepsin-B in isolation was only moderately useful (sensitivity 89%, specificity 62%, AUC 0.75) in separating lymphomatous and TB effusions. However, this last differentiation improved significantly when cathepsin-B was used with respect to the patient's age (sensitivity 72%, specificity 100%, AUC 0.94). In conclusion, panels of 4 (i.e., MMP-9, cathepsin-B, C-reactive protein, chondroitin sulfate), or 3 (i.e., CA19-9, CA15-3, kallikrein-12) different protein

    A 43-year-old male with chronic kidney disease on maintenance hemodialysis presented with breathlessness, cough and right-sided abdominal pain. Examination revealed a large right-sided pleural effusion and subsequent thoracocentesis yielded an exudate. Although the fluid culture was sterile, sputum culture produced Moraxella catarrhalis. Tuberculosis was ruled out by pleural fluid analysis and pleural biopsy. Antibiotics were administered and subsequent radiograms indicated resolution of the effusion. This is a rare case of a large unilateral pleural effusion secondary to M. catarrhalis infection in a nonsmoker with no pre-existing pulmonary pathology. PMID:23393539

    We review the literature on the use of point-of-care ultrasound to evaluate and manage pleural effusions. Point-of-care ultrasound is more sensitive than physical exam and chest radiography to detect pleural effusions, and avoids many negative aspects of computerized tomography. Additionally, point-of-care ultrasound can assess pleural fluid volume and character, revealing possible underlying pathologies and guiding management. Thoracentesis performed with ultrasound guidance has lower risk of pneumothorax and bleeding complications. Future research should focus on the clinical effectiveness of point-of-care ultrasound in the routine management of pleural effusions and how new technologies may expand its clinical utility.

    Background The presence of tumour cells in pleural fluid or tissue defines an effusion as malignant. Cytology analysis of the pleural fluid has about 60% diagnostic sensitivity. Several tests have been proposed to improve diagnosis—among them, the concentrations of tumour markers in pleural fluid. We evaluated whether the concentrations of tumour markers in pleural fluid could improve the diagnosis of malignant pleural effusion (mpe) when cytology is doubtful. Methods Lymphocytic pleural fluids secondary to tuberculosis or malignancy from 156 outpatients were submitted for cytology and tumour marker quantification [carcinoembryonic antigen (cea), cancer antigen 15-3 (ca15-3), carbohydrate antigen 19-9 (ca19-9), cancer antigen 72-4 (ca72-4), cancer antigen 125 (ca125), and cyfra 21-1). Oneway analysis of variance, the Student t-test or Mann–Whitney test, and receiver operating characteristic curves were used in the statistical analysis. Results Concentrations of the tumour markers cea, ca15-3, ca125, and cyfra 21-1 were higher in mpes than they were in the benign effusions (p < 0.001), regardless of cytology results. The markers ca19-9 and ca72-4 did not discriminate malignant from benign effusions. When comparing the concentrations of tumour markers in mpes having positive, suspicious, or negative cytology with concentrations in benign effusions, we observed higher levels of cea, ca15-3, cyfra 21-1, and ca125 in malignant effusions with positive cytology (p = 0.003, p = 0.001, p = 0.002, and p = 0.001 respectively). In pleural fluid, only ca125 was higher in mpes with suspicious or negative cytology (p = 0.001) than in benign effusions. Conclusions Given high specificity and a sensitivity of about 60%, the concentrations of tumour markers in pleural effusions could be evaluated in cases of inconclusive cytology in patients with a high pre-test chance of malignancy or a history of cancer.

    Purpose To evaluate the association of pleural tags with visceral pleural invasion of non-small cell lung cancer (NSCLC) that does not abut the pleural surface. Materials and Methods This retrospective study was approved by the institutional review board. Informed consent was waived. The study of NSCLC that does not abut the pleura in 141 patients (44 patients [31.2%] with visceral pleural invasion proved by pathologic analysis and 97 patients [68.8%] without pleural invasion) was conducted at a single tertiary center. The pleural tags were classified into three types (type 1, one or more linear pleural tag; type 2, one or more linear pleural tag with soft tissue component at the pleural end; and type 3, one or more soft tissue cord-like pleural tag) and prioritized into types 3, 2, and 1 when more than one type was present. Diagnostic accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and positive likelihood ratio (LR) were calculated. Results In the absence of pleural tags, no pleural invasion was found. The presence of type 2 pleural tags was moderately associated with visceral pleural invasion with the following results: positive LR, 5.06; accuracy, 71%; sensitivity, 36.4%; specificity, 92.8%; PPV, 76.2%; and NPV, 69.6%. Type 1 pleural tags provided weak evidence to rule out visceral pleural invasion (positive LR, 0.38). Type 3 pleural tags indicated minimal increase in the likelihood of visceral pleural invasion (positive LR, 1.68). Conclusion Type 2 pleural tags on conventional CT images can increase the accuracy of early diagnosis of visceral pleural invasion by NSCLC that does not abut the pleura. (©) RSNA, 2015.

    In-vivo light Dosimetry for patients undergoing photodynamic therapy (PDT) is one of the important dosimetry quantities critical for predicting PDT outcome. This study examines the light fluence (rate) delivered to patients undergoing pleural PDT as a function of treatment time, treatment volume and surface area, and its accuracy as a function of the calibration accuracies of each isotropic detector and the calibration integrating sphere. The patients studied here were enrolled in Phase II clinical trial of Photofrin-mediated PDT for the treatment of non-small cell lung cancer with pleural effusion. The ages of the patients studied varied from 34 to 69 year old. All patients were administered 2mg per kg body weight Photoprin 24 hours before the surgery. Patients undergoing photodynamic therapy (PDT) are treated with laser light with a light fluence of 60 J/cm^2 at 630nm. Fluence rate (mW/cm^2) and cumulative fluence (J/cm^2) was monitored at 7 different sites during the entire light treatment delivery. Isotropic detectors were used for in-vivo light dosimetry. The anisotropy of each isotropic detector was found to be within 30%. The mean fluence rate delivery varied from 37.84 to 94.05 mW/cm^2 and treatment time varied from 1762 to 5232s. We have established a correlation between the treatment time and the treatment volume. The results are discussed using an integrating sphere theory and the measured tissue optical properties. The result can be used as a clinical guideline for future pleural PDT treatment.

    Background Malignant pleural effusions (MPE) are a common and fatal complication in cancers including lung or breast cancers, or malignant pleural mesothelioma (MPM). MPE animal models and immunotherapy trials in MPM patients previously suggested defects of the cellular immunity in MPE. However only few observational studies of the immune response were done in MPM patients, using questionable control groups (transudate…). Methods We compared T cell populations evaluated by flow cytometry from blood and pleural effusion of untreated patients with MPM (n = 58), pleural metastasis of adenocarcinoma (n = 30) or with benign pleural lesions associated with asbestos exposure (n = 23). Blood and pleural fluid were also obtained from healthy subjects, providing normal values for T cell populations. Results Blood CD4+ or CD8+ T cells percentages were similar in all groups of patients or healthy subjects. Whereas pleural fluid from healthy controls contained mainly CD8+ T cells, benign or malignant pleural effusions included mainly CD4+ T cells. Effector memory T cells were the main T cell subpopulation in pleural fluid from healthy subjects. In contrast, there was a striking and selective recruitment of central memory CD4+ T cells in MPE, but not of effector cells CD8+ T cells or NK cells in the pleural fluid as one would expect in order to obtain an efficient immune response. Conclusions Comparing for the first time MPE to pleural fluid from healthy subjects, we found a local defect in recruiting effector CD8+ T cells, which may be involved in the escape of tumor cells from immune response. Further studies are needed to characterize which subtypes of effector CD8+ T cells are involved, opening prospects for cell therapy in MPE and MPM. PMID:23816056

    The aim is to examine whether the changes in pleural fluid interleukin (IL)-1β, IL-2, IL-6, and IL-8 levels were significant in differential diagnosis of childhood pleural effusions. IL-1β, IL-2, IL-6, and IL-8 levels in pleural fluids of all 36 patients were measured. The levels of IL-1β, IL-2, IL-6, and IL-8 in pleural fluids were statistically significantly higher in the transudate group compared with those of the exudate group. The levels of IL-1β, IL-6, and IL-8 were also found to be statistically significantly higher in the empyema group compared with both the parapneumonic and the tuberculous pleural effusion groups. The levels of IL-2 and IL-6 were detected to be statistically significantly higher in the tuberculous pleural effusion group in comparison with those of the parapneumonic effusion group. The results showed that pleural fluids IL-1β, IL-2, IL-6, and IL-8 could be used in pleural fluids exudate and transudate distinction. PMID:15770060

    Thoracic trauma or pneumothorax can result in pleural fluid eosinophilia. In this study we investigated the role of the eosinophilopoietic cytokine IL-5 in three cases of post-traumatic eosinophilic pleural effusions (EPE). Using a specific immunoenzymatic assay, significant levels of IL-5 were found in EPE (range 100-3000 pg/ml), while IL-5 was undetectable (< 25 pg/ml) in corresponding serum samples and in non-eosinophilic pleural fluids. IL-5 present in pleural fluids was found bioactive in a proliferative assay using a mouse CTLL-2 cell line transfected with the cDNA corresponding to the alpha chain of the human IL-5 receptor. Using a reverse polymerase chain reaction (PCR) method, we found IL-5 mRNA expression within pleural mononuclear cells from patients with EPE, but not in corresponding peripheral blood mononuclear cells (PBMC), confirming that IL-5 is synthesized locally in the pleural cavity. In the two cases in which pleural CD4+ cells were purified, these cells were identified as the major source of IL-5. Taken together, these data indicate that the development of post-traumatic EPE is related to a local secretion of IL-5 by CD4+ cells present in the pleural cavity. Images Fig. 1 PMID:8100745

    Asbestos-induced pleural fibrosis is the most common radiographic abnormality among asbestos-exposed persons. Circumscribed pleural plaques and diffuse pleural thickening account for more than 90% of the asbestos-induced chest wall abnormalities, and their prevalence is expected to increase for the next 15 to 20 years. Several investigators have recently found that pleural plaques and diffuse pleural thickening independently contribute to the development of restrictive lung function. The work presented in this paper indicates that asbestos-induced pleural fibrosis is also associated with evidence of interstitial lung abnormalities, even among those with normal parenchyma on chest X-ray film. These parenchymal abnormalities include an increased percentage of lymphocytes on bronchoalveolar lavage and an increase in the interstitial changes observed on high-resolution chest computerized tomography (HRCT) scan. However, neither a lymphocytic alveolitis nor an interstitial parenchymal fibrosis influenced the relationship between pleural fibrosis and restrictive lung function. We conclude that asbestos-induced pleural disease contributes to the development of restrictive lung function and identify a group of exposed individuals who are at excess risk of asbestosis.

    Pleural fluid analysis yields important diagnostic information in pleural effusions in combination with clinical history, examination, and radiology. For more than 30 years, the initial and most pragmatic step in this process is to determine whether the fluid is a transudate or an exudate. Light's criteria remain the most robust in separating the transudate-exudate classification which dictates further investigations or management. Recent studies have led to the evaluation and implementation of a number of additional fluid analyses that may improve the diagnostic utility of this method. This paper discusses the current practice and future direction of pleural fluid analysis in determining the aetiology of a pleural effusion. While this has been performed for a few decades, a number of other pleural characteristics are becoming available suggesting that this diagnostic tool is indeed a work in progress. PMID:22448326

    A 19-year-old man with large malignant pleural and pericardial effusions with tamponade physiology and signs of congestive heart failure presented for emergent subxiphoid pericardial window. Surgical drainage of the pericardium was complicated by a paradoxical cardiovascular collapse that failed to respond to pressors and intravenous fluids. Suspecting a pericardial perforation, a median sternotomy was performed and revealed an intact heart. The arterial pressure was promptly restored after drainage of the pleural effusion. It is proposed that, in patients presenting with tamponading pericardial and pleural effusions, drainage of the pleural effusion be given priority. The pathophysiology of low cardiac output states resulting from pericardial and large pleural effusion is discussed and the literature reviewed. PMID:27555190

    Pleural effusions are one of the rarest complications reported in patients with silicone gel filled breast implants. The silicone implants have potential to provoke chronic inflammation of pleura and subsequent pulmonary complications such as pleural effusion. Herein, we report a 44-year-old female who presented with left sided pleural effusion, six weeks after a silicone breast implantation surgery. The most common infectious, inflammatory, and malignant causes of pleural effusion were excluded with pleural fluid cytology and cultures. With recurrent effusion in the setting of recent surgery, the chemical reaction to silicone breast implants was sought and exploration was performed which revealed foreign body reaction (FBR) to silicone material. The symptoms dramatically improved after the explantation. PMID:26693375

    A case of sarcomatoid malignant pleural mesothelioma showing extremely rare growth pattern is described. A 63-year-old man presented to our hospital with left pleural effusion. A computed tomography (CT) scan of the chest showed diffusely thickened left visceral and parietal pleura associated with intermingled pulmonary infiltrative shadowing. Biopsy of the pleura under general anaesthesia confirmed the diagnosis of sarcomatoid malignant pleural mesothelioma. The patient underwent left extra-pleural pneumonectomy. Histopathologically, the sarcomatoid spindle tumour cells changed their morphology to polygonal cells in the pulmonary parenchyma and grew upwards, filling the alveolar space without the destruction of its septa, showing an alveolar-filling growth pattern. The current report indicates a case of sarcomatoid pleural mesothelioma that shows an alveolar-filling growth pattern, despite having not been thoroughly categorized in the World Health Organization (WHO) classification.

    An algorithm of preoperative mediastinal nodal staging with endobronchial/endoesophageal ultrasonography (EBUS/EUS) and transcervical extended mediastinal lymphadenectomy (TEMLA) combined with laparoscopy/peritoneal lavage and cytology was analyzed to establish the realistic criteria for radical multimodality treatment of malignant pleural mesothelioma (MPM). The algorithm included computed tomography (CT), thoracoscopy with multiple pleural biopsies and talc pleurodesis, EBUS/EUS and one-stage TEMLA and laparoscopy/peritoneal lavage and cytology of the fluid. Forty-two patients were diagnosed from 1 January 2004 to 31 December 2008. There were 16 women and 26 men in ages ranging from 43 to 77 years (mean 57.8); 31 epithelioid, 2 sarcomatoid and 9 biphasic type MPM. 21/42 patients were considered possible candidates for multimodality treatment. Three patients who received neoadjuvant chemotherapy were excluded from this study. EBUS/EUS was performed to stage the mediastinal nodes. In 3/18 patients metastatic nodes were discovered. In the rest of the 15 patients simultaneous TEMLA and laparoscopy/peritoneal lavage and cytology of the fluid were performed. In three patients TEMLA was positive, in six patients laparoscopy was positive and in two patients both TEMLA and laparoscopy were positive. Finally, 4/42 (9.5%) patients underwent thoracotomy with one exploration (chest wall infiltration) and three pleuropneumonectomies with the subsequent chemo- and radiotherapy. The proposed algorithm of preoperative staging spared the majority of MPM patients from futile surgery. PMID:19843550

    Splenosis is a rare condition described as ectopic splenic tissue implantation generally after a splenic rupture. A 35-year-old male patient who had a history of splenectomy operation due to gunshot wound seven years ago was referred to our hospital with complaints, including exhaustion, sweating and shortness of breath. Thoracic computed tomography of the patient showed nodular pleural thickenings at the level of the left lower lobe, which proved to be unrelated with the presenting symptoms. The patient underwent a minithoracotomy for diagnosis and treatment. During the intraoperative observation, dark-colored, soft, multiple nodular lesions with a biggest size of 2 cm inside the visceral pleura over an area of 5 x 10 cm in dimension were observed. Also, a few tiny nodules in the lung parenchyma approximately 1-cm deep to the pleural nodules were palpated. The lesions were excised. The histopathological examination of the specimen showed splenic tissue in the lung parenchyma and pleura, so the lesions were accepted as splenosis. Pleuropulmonary splenosis, which develops generally after simultaneous rupture of the diaphragma and spleen, is a very rare condition. Most of the patients are asymptomatic and the lesions are detected accidentally. If the diagnosis can be made preoperatively, surgical excision is not needed. Images Figure 1 Figure 2 PMID:16916134

    The ability to deliver uniform light dose in Photodynamic therapy (PDT) is critical to treatment efficacy. Current protocol in pleural photodynamic therapy uses 7 isotropic detectors placed at discrete locations within the pleural cavity to monitor light dose throughout treatment. While effort is made to place the detectors uniformly through the cavity, measurements do not provide an overall uniform measurement of delivered dose. A real-time infrared (IR) tracking camera is development to better deliver and monitor a more uniform light distribution during treatment. It has been shown previously that there is good agreement between fluence calculated using IR tracking data and isotropic detector measurements for direct light phantom experiments. This study presents the results of an extensive phantom study which uses variable, patient-like geometries and optical properties (both absorption and scattering). Position data of the treatment is collected from the IR navigation system while concurrently light distribution measurements are made using the aforementioned isotropic detectors. These measurements are compared to fluence calculations made using data from the IR navigation system to verify our light distribution theory is correct and applicable in patient-like settings. The verification of this treatment planning technique is an important step in bringing real-time fluence monitoring into the clinic for more effective treatment.

    Purpose: We previously reported our technique for delivering intensity modulated radiation therapy (IMRT) to the entire pleura while attempting to spare the lung in patients with malignant pleural mesothelioma (MPM). Herein, we report a detailed pattern-of-failure analysis in patients with MPM who were unresectable or underwent pleurectomy/decortication (P/D), uniformly treated with hemithoracic pleural IMRT. Methods and Materials: Sixty-seven patients with MPM were treated with definitive or adjuvant hemithoracic pleural IMRT between November 2004 and May 2013. Pretreatment imaging, treatment plans, and posttreatment imaging were retrospectively reviewed to determine failure location(s). Failures were categorized as in-field (within the 90% isodose line), marginal (<90% and ≥50% isodose lines), out-of-field (outside the 50% isodose line), or distant. Results: The median follow-up was 24 months from diagnosis and the median time to in-field local failure from the end of RT was 10 months. Forty-three in-field local failures (64%) were found with a 1- and 2-year actuarial failure rate of 56% and 74%, respectively. For patients who underwent P/D versus those who received a partial pleurectomy or were deemed unresectable, the median time to in-field local failure was 14 months versus 6 months, respectively, with 1- and 2-year actuarial in-field local failure rates of 43% and 60% versus 66% and 83%, respectively (P=.03). There were 13 marginal failures (19%). Five of the marginal failures (38%) were located within the costomediastinal recess. Marginal failures decreased with increasing institutional experience (P=.04). Twenty-five patients (37%) had out-of-field failures. Distant failures occurred in 32 patients (48%). Conclusions: After hemithoracic pleural IMRT, local failure remains the dominant form of failure pattern. Patients treated with adjuvant hemithoracic pleural IMRT after P/D experience a significantly longer time to local and distant failure than

    Background: Medical thoracoscopy is a minimally invasive procedure used in diagnostic and therapeutic applications for pleural diseases. In this study, we describe our experience in the outcome and analysis of thoracoscopy in undiagnosed pleural effusion presenting to our center. Materials and Methods: This is a prospective study conducted over last 2 years. We performed thoracoscopy in 129 cases of undiagnosed exudative pleural effusions using rigid thoracoscope. Clinical, radiological, cyto and histopathological data of the patients were collected prospectively and analyzed. Results: The overall diagnostic yield of thoracoscopic pleural biopsy was 110/129 (85.2%) in patients with undiagnosed pleural effusion, and 19/129 (14.8%) patients remained unexplained. Histopathological diagnosis confirmed malignancy in 66.4% patients (both primary and metastatic pleural carcinoma), tuberculosis in 28.2%, others including parapneumonic effusion in 4 cases followed by multiple myeloma, lupus pleuritis, and pulmonary langerhans cell histiocytosis in one case each. Procedure-related mortality was nil. Minor complications related to the procedure include hemorrhage, subcutaneous emphysema, etc. Conclusion: Thoracoscopy is relatively a safe and well-tolerated procedure with high diagnostic accuracy in undiagnosed pleural effusions, decreasing the need of formal diagnostic thoracotomy. Every chest physician must, therefore, consider this procedure to decrease the time lag in achieving the final diagnosis and to initiate the treatment as early as possible. PMID:27625443

    Lymphocytic pleurisy is commonly observed in tuberculosis and cancer. Noninvasive biomarkers are needed to distinguish tuberculous pleural effusion (TPE) from malignant pleural effusion (MPE) because current clinical diagnostic procedures are often invasive. We identified immune response biomarkers that can discriminate between TPE and MPE. Fourteen pleural effusion biomarkers were compared in 22 MPE patients and five TPE patients. Of the innate immunity biomarkers, the median levels of interleukin (IL)-1β and interferon-induced protein-10 (IP-10) were higher in TPE patients than in MPE patients (P<0.05 and P<0.01, respectively). Of the adaptive immunity biomarkers, the median levels of IL-13 and interferon-γ (IFN-γ) were higher in TPE patients than in MPE patients (P<0.05). In addition, the levels of basic fibroblast growth factor were higher in MPE patients than in TPE patients (P<0.05). Receiver operator characteristic analysis of these biomarkers was performed, resulting in the highest area under the curve (AUC) for IP-10 (AUC =0.95, 95% confidence interval, P<0.01), followed by IL-13 (AUC =0.86, 95% confidence interval, P<0.05). Our study shows that five biomarkers (IL-1β, IP-10, IFN-γ, IL-13, and basic fibroblast growth factor) have a potential diagnostic role in differentiating TPE from MPE, particularly in lung cancer-related MPE.

    Objective: To determine diagnostic yield of Closed Pleural Biopsy (CPB) and Cytology in Exudative Pleural Effusion (PE). Methods: This prospective comparative study was conducted at Chest Unit-II & Medical Unit-IV of Dow University of Health Sciences, Karachi Pakistan from January 2011 till December 2014. Results: Ninety-four patients with exudative PE were finally included. The mean age (SD) was 44.0 (13.8) years. Overall Specific Diagnosis was reached in 76/94 patients; 46 Tuberculosis PE (TPE) & 30 Malignant PE (MPE). CPB diagnosed all TPE patients alone and 28/30 of MPE. Cytology diagnosed only 10/30 patients of MPE with 8 patients having both CPB & Cytology positive for malignancy whereas in the remaining two cases only Cytology positive. The sensitivity of CPB in detecting TPE and MPE was 93.9% and 82.4% respectively whereas specificity for both was 100%. The diagnostic yield of cytology in detecting MPE is only (33.3%). The diagnostic yield of CPB for TPE and MPE is 100% and 93.3% respectively. The overall specific diagnostic yield of CPB is 78.7%. Conclusion: CPB is better than pleural fluid cytology alone with the later adding little to diagnostic yield when both combined in distinguishing TPE from MPE, the two main differential of exudative PE in a TB-Endemic country.

    A 55-year-old carpenter developed pleurisy with pleural effusion on the right side in 2000 and on the left side in 2003. No known causes of pleurisy were found. He had been occupationally exposed to asbestos during a 6-month-period in 1971 while working with roof sheets made of asbestos cement. In the literature there is evidence of asbestos being a cause of benign pleural effusion. We found it likely that the pleurisy with pleural effusion found in this patient was an occupational condition and it should therefore be notified as industrial injury. PMID:21040677

    A pleural effusion is excess fluid that collects in the pleural cavity, the fluid-filled space that surrounds the lungs. Surplus amounts of such fluid can impair breathing by limiting the expansion of the lungs during inhalation. Measuring the fluid volume is indicative of the effectiveness of any treatment but, due to the similarity to surround regions, fragments of collapsed lung present and topological changes; accurate quantification of the effusion volume is a difficult imaging problem. A novel code is presented which performs conditional region growth to accurately segment the effusion shape across a dataset. We demonstrate the applicability of our technique in the segmentation of pleural effusion and pulmonary masses.

    Pleural pigtail catheter placement is associated with many complications including pneumothorax, hemorrhage, and chest pain. Air embolism is a known but rare complication of pleural pigtail catheter insertion and has a high risk of occurrence with positive pressure ventilation. In this case report, we present a 50-year-old male with bilateral pneumonia who developed a pneumothorax while on mechanical ventilation with continuous positive airway pressure mode. During the placement of the pleural pigtail catheter to correct the pneumothorax, the patient developed a sudden left sided body weakness and became unresponsive. An air embolism was identified in the right main cerebral artery, which was fatal.

    Pleural effusion in the presence of cirrhosis and ascites is well recognized. Peritoneal fluid is thought to enter the pleural cavity either because of overloaded lymphatics or a structural defect between the peritoneal and chest cavities. Pleural effusion rarely occurs in the absence of demonstrable ascites. This report describes the scintigraphic diagnosis of peritoneo-pleural communication in a patient with cryptogenic cirrhosis and pleural effusion without ascites. PMID:7805325

    Objective To determine the patho-mechanism of pleural effusion or hydropneumothorax in Mycobacterium avium complex (MAC) lung disease through the computed tomographic (CT) findings. Materials and Methods We retrospectively collected data from 5 patients who had pleural fluid samples that were culture-positive for MAC between January 2001 and December 2013. The clinical findings were investigated and the radiological findings on chest CT were reviewed by 2 radiologists. Results The 5 patients were all male with a median age of 77 and all had underlying comorbid conditions. Pleural fluid analysis revealed a wide range of white blood cell counts (410–100690/µL). The causative microorganisms were determined as Mycobacterium avium and Mycobacterium intracellulare in 1 and 4 patients, respectively. Radiologically, the peripheral portion of the involved lung demonstrated fibro-bullous changes or cavitary lesions causing lung destruction, reflecting the chronic, insidious nature of MAC lung disease. All patients had broncho-pleural fistulas (BPFs) and pneumothorax was accompanied with pleural effusion. Conclusion In patients with underlying MAC lung disease who present with pleural effusion, the presence of BPFs and pleural air on CT imaging are indicative that spread of MAC infection is the cause of the effusion.

    The causes and situation of exudative pleural effusion vary from one area to another. A cross-sectional study was conducted on 327 patients with exudative pleural effusion in South Khorasan province (Iran). The patients were older than 12 years and comprised 172 (52.6%) males and 155 (47.4%) females. The study commenced in 2007 with seven years duration. The Light’s criteria were used to define exudative effusion. Procedures including pleural fluid analysis, microbiological study, pleural biopsy, and systemic investigations were conducted to determine the special cause of pleural effusion. The mean age of the patients was 63.4±18.4 years. Malignancies, tuberculosis, and parapneumonia pleural exudation were diagnosed in 125 (38.2%), 48 (14.7%), and 45 (13.8%) cases, respectively. Among malignant effusions, metastasis from lung cancer made 48 (38.4%) of the cases. The origin of metastasis was not determined in 44 (35.2%) patients. The mean age of patients was not significantly different between malignant (66.9±14.3 years) and tuberculosis (63.9±19.7 years) cases (P=0.16). The older age of tuberculosis patients could be a new discussion point on the overall impression created on the subject of tuberculosis pleural exudation (TB-PLE) occurring in young people.

    PubMed

    Lew, Susie Q

    2010-01-01

    Hydrothorax in a patient treated with peritoneal dialysis (PD) poses a diagnostic dilemma. Hydrothorax due to migration of dialysis fluid across the diaphragm and into the pleural space creates a serious complication of PD but generally does not threaten life. Shortness of breath causes the patient to seek medical attention. A sudden diminution in dialysis adequacy or poor ultrafiltration rate constitutes a unique marker for patients treated with PD compared to the general population. This article reviews the etiology for hydrothorax specifically in the PD population. Thoracentesis with chemical analysis of the fluid, imaging studies with and without contrast or markers, and video-assisted thoracoscopic surgery play important roles in the evaluation of hydrothorax. A conservative PD regimen, surgical intervention, and pleurodesis provide treatment options to those receiving PD. PMID:20056973

    Malignant pleural mesothelioma (MPM) is associated with a poor prognosis. The main components of multimodality treatment include surgery, chemotherapy, and radiation therapy. Surgery remains controversial. Two procedures are currently offered: extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D). The recent scientific literature suggests that P/D is a well-tolerated procedure, with the potential of becoming a default procedure in multimodality regimens. However, the precise treatment schemes and surgical procedures are yet to be established. In our study, we review the advantages and disadvantages of EPP and P/D, summarize the post-EPP and post-P/D observations (including mortality, morbidity, and median survival time), and discuss the choice of surgical technique (EPP vs. P/D). Moreover, we highlight the aspects of the multimodality treatments that are offered to MPM patients, including chemotherapy, radiotherapy, intensity-modulated radiation therapy, and other types of therapy.

    Malignant pleural effusion (MPE) is a common but serious condition that is related with poor quality of life, morbidity and mortality. Its incidence and associated healthcare costs are rising and its management remains palliative, with median survival ranging from 3 to 12 months. During the last decade there has been significant progress in unravelling the pathophysiology of MPE, as well as its diagnostics, imaging, and management. Nowadays, formerly bed-ridden patients are genotyped, phenotyped, and treated on an ambulatory basis. This article attempts to provide a comprehensive overview of current advances in MPE from bench to bedside. In addition, it highlights unanswered questions in current clinical practice and suggests future directions for basic and clinical research in the field. PMID:27246596

    Tube thoracostomy is usually the first step to treat several thoracic/pleural conditions such as pneumothorax, pleural effusions, haemothorax, haemo-pneumothorax and empyema. Today, a wide range of drains is available, ranging from small to large bore ones. Indications for an appropriate selection remains yet matter of debate, especially regarding the use of small bore catheters. Through this paper, we aimed to retrace the improvements of drains through the years and to review the current clinical indications for chest drain placement in pleural/thoracic diseases, comparing the effectiveness of small-bore drains vs. large-bore ones.

    Malignant pleural effusion (MPE) is common and difficult to treat. In the vast majority of patients the presence of MPE heralds incurable disease, associated with poor quality of life, morbidity and mortality. Current therapeutic approaches are inefficient and merely offer palliation of associated symptoms. Recent scientific progress has shed light in the biologic processes governing the mechanisms behind the pathobiology of MPE. Pleural based tumors interfere with pleural fluid drainage, as well as the host vasculature and immune system, resulting in decreased fluid absorption and increased pleural fluid production via enhanced plasma extravasation into the pleural space. In order to achieve this feat, pleural based tumors must elicit critical vasoactive events in the pleura, thus forming a favorable microenvironment for tumor dissemination and MPE development. Such properties involve specific transcriptional signaling cascades in addition to secretion of important mediators which attract and activate host cell populations which, in turn, impact tumor cell functions. The dissection of the biologic steps leading to MPE formation provides novel therapeutic targets and recent research findings provide encouraging results towards future therapeutic innovations in MPE management.

    Pleural effusion is a frequent complication in patients undergoing hemodialysis (HD). We report a patient on HD with a novel cause of recurrent unilateral pleural effusion. A 45-year-old female patient on long-term maintenance HD presented to us with recurrent unilateral pleural effusion. She had a history of poor quality dialysis, severe anemia and severe hypertension. Despite correcting these factors and even after undergoing successful renal transplantation, she continued to have recurrent effusion. Left upper extremity venography demonstrated severe stenosis of the subclavian vein and an increased venous flow in the ipsilateral arteriovenous (AV) fistula. Ligation of the AV fistula led to dramatic resolution of the pleural effusion. Hemodialysis patients who develop unexplained pleural effusions ipsilateral to a functioning AV fistula should be investigated for stenosis in the brachiocephalic vein, particularly those patients who have had previous catheterizations of the jugular or subclavian veins on the same side as the effusion. Correcting the stenosis by venous angioplasty and/or ligation of the ipsilateral fistula can dramatically resolve the pleural effusion. A high index of suspicion is required to diagnose this complication for meaningful intervention. PMID:22237229

    About 20% of hospitalized patients with bacterial pneumonia have an accompanying pleural effusion. Parapneumonic effusions (PPE) are associated with a considerable morbidity and mortality. The main decision in managing a patient with a PPE is whether to insert a chest tube (complicated PPE). Imaging (i.e., chest radiograph, ultrasound and computed tomography) and pleural fluid analysis (i.e., pH, glucose, lactate dehydrogenase, bacterial cults) provide essential information for patient management. Therefore, all PPEs should be aspirated for diagnostic purposes. This may require image-guidance if the effusion is small or heavily loculated. According to the current guidelines, any PPE that fulfills at least one of the following criteria should be drained: size > or = 1/2 of the hemithorax, loculations, pleural fluid pH < 7.20 (or alternatively pleural fluid glucose < 60 mg/dl), positive pleural fluid Gram stain or culture, or purulent appearance. The key components of the treatment of complicated PPE and empyema are the use of appropriate antibiotics, provision of nutritional support, and drainage of the pleural space by one of the following methods: therapeutic thoracentesis, tube thoracostomy, intrapleural fibrinolytics, thoracoscopy with breakdown of adhesions or thoracotomy with decortication. The routine use of intrapleural fibrinolytic therapy remains controversial. (c) 2009 Elsevier España, S.L. All rights reserved. PMID:19889319

    Lungs from seven cases of diffuse pleural fibrosis with known asbestos exposure were studied to determine the gross and microscopic pathological features and relate these to the analysed mineral fibre content of the lung. All seven individuals had had substantial exposure, ranging from two to 25 years, and chronic chest problems and at necropsy all cases met the criteria for compensatable disease. Macroscopically, all had extensive visceral pleural fibrosis and extensive areas of adhesions, and four also had discrete parietal pleural plaques. The histological features were similar in all the cases--most strikingly the basket weave pattern of the thickened pleura and a dense subpleural parenchymal interstitial fibrosis with fine honeycombing, extending up to 1 cm into the underlying lung. The similar histological appearances raise the possibility that diffuse pleural fibrosis and pleural plaques have a similar pathogenesis. Amphibole asbestos (crocidolite and amosite) counts were high in six of the seven cases and chrysotile counts in four; four cases had high mullite counts, but the importance of this is not known. It is concluded that diffuse pleural fibrosis is a specific asbestos associated entity, of uncertain pathogenesis, with mineral fibre counts falling between those found with plaques and those in minimal asbestosis.

    Metastatic melanoma is a rare form of skin cancer, but one that comes with a high mortality rate. Pulmonary involvement is frequently seen in metastatic melanoma with only 2% of malignant melanoma patients with thorax metastasis presenting with pleural effusions. Herein, we report an extremely rare case of black pleural effusion from thoracic metastasis of cutaneous malignant melanoma. A 74-year-old man with known metastatic melanoma presented with a 1-month history of worsening lower back and hip pain and was found to have extensive osseous metastatic disease and multiple compression fractures. The patient underwent an uneventful kyphoplasty; however, the following day, he became acutely hypoxic and tachypneic with increased oxygen requirements. Radiographic evaluation revealed new bilateral pleural effusions. Bedside thoracentesis revealed a densely exudative, lymphocyte-predominant black effusion. Cytological examination showed numerous neoplastic cells with melanin deposition. A diagnosis of thoracic metastasis of malignant melanoma was established based on the gross and microscopic appearance of the pleural fluid. To the best of our knowledge, this is the first reported case of black pleural effusions secondary to metastatic melanoma in the United States. Despite the rarity of this presentation, it is important to determine the etiology of the black pleural effusion and to keep metastatic melanoma as a differential diagnosis. PMID:26078741

    Infections caused by carbapenem-resistant, Gram-negative bacteria are an increasing clinical challenge, since the antimicrobial treatment options are often limited to colistin methanesulfonate. No data are available regarding the pharmacokinetics of colistin in pleural fluid. We report the case of a 92-year old man with ventilator-associated pneumonia and pleurisy caused by Acinetobacter baumannii and Escherichia coli, which were both multidrug-resistant. After an unsuccessful treatment with intravenous colistin methanesulfonate and imipen-em-cilastatin, the addition of intra-pleural colistin methanesulfonate to the intravenous treatment led to a prompt clinical, radiological and microbiological resolution. This is the first report of a successful use of intra-pleural colistin in the literature. The intra-pleural colistin therapy should be considered in selected cases of pleurisy caused by multi-resistant Gram-negative bacteria. PMID:25276329

    PDT dose is the product of the photosensitizer concentration and the light fluence in the target tissue. For improved dosimetry during plural photodynamic therapy (PDT), a PDT dose dosimeter was developed to measure both the light fluence and the photosensitizer concentration simultaneously in the same treatment location. Light fluence and spectral data were rigorously compared to other methods of measurement (e.g. photodiode, multi-fiber spectroscopy contact probe) to assess the accuracy of the measurements as well as their uncertainty. Photosensitizer concentration was obtained by measuring the fluorescence of the sensitizer excited by the treatment light. Fluence rate based on the intensity of the laser spectrum was compared to the data obtained by direct measurement of fluence rate by a fiber-coupled photodiode. Phantom studies were done to obtain an optical property correction for the fluorescence signal. Measurements were performed in patients treated Photofrin for different locations in the pleural cavity. Multiple sites were measured to investigate the heterogeneity of the cavity and to provide cross-validation via relative dosimetry. This novel method will allow for accurate real-time determination of delivered PDT dose and improved PDT dosimetry. PMID:27053825

    To verify the hypothesis that by enmeshing lubricants, microvilli reduce the coefficient of kinetic friction (μ) of pleural mesothelium, μ was measured during reciprocating sliding of rabbit's visceral against parietal pleura before and after addition of hyaluronan, and related to the morphological features of the microvillar network. Because no relation was found between μ or μ changes after hyaluronan and microvillar characteristics, the latter are not determinants of the frictional forces which oppose sliding of normal mesothelial surfaces under physiological conditions, nor of the effects of hyaluronan. Addition of hyaluronan increased μ slightly but significantly in normal specimens, probably by altering the physiological mix of lubricants, but decreased μ of damaged mesothelia, suggesting protective, anti-abrasion properties. Indeed, while sliding of an injured against a normal pleura heavily damaged the latter and increased μ when Ringer was interposed between the surfaces, both effects were limited or prevented when hyaluronan was interposed between the injured and normal pleura before onset of sliding.

    Malignant pleural mesothelioma (MPM), the incidence increased with each passing day, is an important lethal disease due to the limited survive with available treatment methods and with the lack of a standard treatment. Response and survive rates of cytotoxic agents which is used in MPM treatment are not good enough. Therefore, treatment studies of MPM seem to quite important and urgent. In cancer therapy, convensional chemotherapeutic agent applications, due to the lack of selectivity, lead to systemic toxicity. Besides the limited solubility of the agent used, the distribution between the cells is weak. It is very difficult to the pass through cellular barriers, particularly, drug resistance may develop to the treatment. All of these reasons lead to failure in the treatment process. Because of the fact that cytotoxic drugs either kill the rapidly growing and dividing cells or make them disfunctional by showing toxic effect on them, to avoid the side effects and to make an inherent effect for cytotoxic drug of active ingredient given for treatment on tumor, different studies have been under investigation. At the present time, nanocarriers as one of these solutions seem to have an important place. Nanocarriers are promising for the development of therapeutic effectiveness and safety. It seems that use of the nanocarrier in the treatment of mesothelioma has a potential, as effective alternative a method, with improve of the drug efficacy and reduce of toxicity in normal tissues.

    Pleural mesothelioma has been diagnosed in 52 patients in three hospitals on Merseyside between 1955 and 1970, 60% being diagnosed from operation specimens and the rest from postmortem tissues. Necropsies eventually held on nearly half the operation cases confirmed the diagnosis, giving a necropsy rate of 70% for the series. The morbid anatomy conformed to earlier descriptions except that widespread metastases were much commoner than has usually been described. Histological findings agreed with previous accounts of the tumour, except that, in our hands, special acid mucopolysaccharide staining was less reliable than Southgate's mucicarmine, which was of value in differential diagnosis. Association with asbestos was confirmed from industrial histories in 80% of cases, the commonest industries involved being shipbuilding and repairing in men and sackware repairing in women. Lungs of industrial mesothelioma cases showed basal asbestosis in 17% and excessive asbestos bodies in almost all the rest. Quantitative comparison of asbestos bodies in lung smears from mesothelioma cases compared with lung smears from other Merseyside adults showed much higher counts in the mesothelioma cases. The interval from first exposure to asbestos until appearance of mesothelioma ranged between 13 and 63 years, with a mean of 42 years. We think the incidence of mesothelioma will continue to rise with the increased use of asbestos until about 40 years after adequate protective measures have been taken. Images PMID:5101273

    Background Thoracoscopy with a semirigid instrument is a recent technique for diagnosing pleural diseases. The purpose of this study was to report diagnostic yield and complications of the method. Patients and methods. Patients with pleural effusion of unknown origin and/or pleural irregularities suspicious for pleural malignancy were included after less invasive means of diagnosis had failed. All procedures were performed under local anaesthesia with intravenous sedation/analgesia with a single point of entry with a semirigid thoracoscope (Olympus LTF-160). Data were collected prospectively between 2008 and 2012. Results One hundred fifteen thoracoscopies were performed on 111 patients. The median age was 65 years (range 28–86 years), 14.4% were female and 85.6% male. Seventy-three (65.8%) patients had malignant pleural disease (malignant mesothelioma, metastatic cancer) and 38 (34.2%) had benign disease. The sensitivity, negative predictive value, and accuracy of the procedure for malignancy were 96.0%, 93.0%, and 97.4% respectively. Pleurodesis was carried out in 34 patients; in 32 (94.1%) it was assessed as successful after 1 month. There were 24 adverse events: three empyemas/pleural infections, three bronchopleural fistulae after chest tube placement and lung re-expansion, five patients had excessive pain after pleurodesis, six patients had sedation-associated hypotension, and seven patients had self-limited fever after plerodesis. One patient died 11 days after a procedure for advanced carcinoma. Conclusions Semirigid thoracoscopy is an accurate and safe method for evaluation of pleural diseases and useful for therapeutic talc pleurodesis. PMID:24587782

    Objective To determine the extent of linezolid and ertapenem penetration into the empyemic fluid using a rabbit model of empyema. Methods An empyema was created via the intrapleural injection of Escherichia coli bacteria (ATCC 35218) into the pleural space of New Zealand white rabbits. After an empyema was verified by thoracocentesis, 24 hours post inoculation, linezolid (10 mg/kg) and ertapenem (60 mg/kg) were administered intravenously into 10 and 8 infected empyemic rabbits, respectively. Antibiotic levels were determined in samples of pleural fluid and blood serum, collected serially at 1, 2, 4, 6 and 8 hours, after administration each of the two antibiotics. Results Linezolid as well as ertapenem penetrate well into the empyemic pleural fluid, exhibiting a slower onset and decline compared to the corresponding blood serum levels. Equilibration between blood serum and pleural fluid compartments seems to occur at 1.5 hours for both linezolid and ertapenem, with peak pleural fluid levels (Cmaxpf of 2.02 ± 0.73 «mu»g/ml and Cmaxpf of 3.74 ± 1.39 «mu»g/ml, correspondingly) occurring 2 hours post antibiotics administration and decreasing very slowly thereafter. The serum concentrations for both antibiotics were significantly lower from the corresponding pleural fluid ones during the 8 hours collecting data, with the exception of samples collected at the 1st hour (Cmaxserum of 2.1 ± 1.2 «mu»g/ml for linezolid and Cmaxserum of 6.26 ± 2.98 «mu»g/ml for ertapenem). Conclusion Pleural fluid levels of both antibiotics are inhibitory for common specified pathogens causing empyema. PMID:20482752

    One hundred and one (6%) of 1,678 patient studied had bilateral reexpansion pulmonary oedema(RPO). On the whole, one thousand, seven hundred and seventy nine (1,779) pleural spaces were studied, fifteen pleural spaces (0.8%), with mean age of 23 +/- 4.5 years had RPO. Among these 15 patients with RPO, the mean period of lung collapse before pneumothorax (PThx) was evacuated was 31.8 +/- 21.8 days and for hydrothorax (HThx) was 31.3 +/- 30.1 days; for 15 patients without RPO (controls), matched for age and sex, the mean period of lung collapse before CTTD was 7.5 +/- 4.1 days and 5.4 +/- 1.3 days respectively for PThx and HThx. The differences in the period of lung collapse among patients with RPO and those without, for each pleural disease was statistically significant (P < 0.03). Volume of pleural fluid drained before RPO was noticed was 2196 +/- 1103 mls, for the 15 matched patients without RPO (controls), it was 1060 +/- 115 mls (p < 0.05). Volume of pleural fluid drained among the patients with SR (Severe response), MR (mild to moderate response) and RD (radiological diagnosis) did not correlate with severity of response. We conclude that prevention of RPO is the desired goal in the management of pleural effusion or Pneumothorax. RPO is commonest among young patients who have had lung collapse for 7 or more days. In these circumstances RPO is prevented, its incidence and severity reduced by methods of gradual evacuation of PThx or pleural fluid drainage. PMID:12690682

    Introduction Malignant pleural effusion can complicate most cancers. It causes breathlessness and requires hospitalisation for invasive pleural drainages. Malignant effusions often herald advanced cancers and limited prognosis. Minimising time spent in hospital is of high priority to patients and their families. Various treatment strategies exist for the management of malignant effusions, though there is no consensus governing the best choice. Talc pleurodesis is the conventional management but requires hospitalisation (and substantial healthcare resources), can cause significant side effects, and has a suboptimal success rate. Indwelling pleural catheters (IPCs) allow ambulatory fluid drainage without hospitalisation, and are increasingly employed for management of malignant effusions. Previous studies have only investigated the length of hospital care immediately related to IPC insertion. Whether IPC management reduces time spent in hospital in the patients’ remaining lifespan is unknown. A strategy of malignant effusion management that reduces hospital admission days will allow patients to spend more time outside hospital, reduce costs and save healthcare resources. Methods and analysis The Australasian Malignant Pleural Effusion (AMPLE) trial is a multicentred, randomised trial designed to compare IPC with talc pleurodesis for the management of malignant pleural effusion. This study will randomise 146 adults with malignant pleural effusions (1:1) to IPC management or talc slurry pleurodesis. The primary end point is the total number of days spent in hospital (for any admissions) from treatment procedure to death or end of study follow-up. Secondary end points include hospital days specific to pleural effusion management, adverse events, self-reported symptom and quality-of-life scores. Ethics and dissemination The Sir Charles Gairdner Group Human Research Ethics Committee has approved the study as have the ethics boards of all the participating hospitals. The

    Introduction: Pleural empyema is a severe complication of various diseases. The essential is the inserting a drain into the pleural cavity and evacuation of the pus. Sometimes the pus is very thick and its evacuation and re-expansion of the lung is very difficult. Methods: We report a group of 10 patients with intrapleural administration of Pulmozyme (dornase alpha) in dosages of either 2.5 mg once or on two separate occasions. All of the patients had a chest tube inserted into the pleural cavity. Measurement of viscosity was done before and after the instillation of the dornase alpha. Results: In six patients dornase alfa was introduced into the pleural cavity once. Three of them received this on the 4th whilst the rest were treated with the agent on the 6th day. Four patients received the dornase alpha twice because of the small amount of drainage fluid after the previous instillation. Five patients were discharged from hospital with complete re-expansion of their lungs. Two patients were qualified for a surgical operation since the lung was trapped and did not re-expand. Three patients had to be discharged with a drain as a result of incomplete re-expansion of the lung. In all the patients the density of the pus after administering the dornase alpha decreased and the amount of the pus drainage increased. Conclusions: Dornase alpha may be used in some patients with pleural empyema with good results. PMID:26885174

    Background: One of the most common indications for pleuroscopy is undiagnosed pleural effusion, which comprises about 25% of all cases of pleural effusions, which remain undiagnosed despite primary tests. Pleuroscopy was performed for the first time in Iran in Masih Daneshvari hospital located in Tehran. The aim of this study was to assess the diagnostic yield of pleuroscopy performed in this center in Iran. Materials and Methods: Three-hundred patients with undiagnosed pleural effusions were enrolled in this study. For all patients, primary tests including pleural effusion analysis, cytology and closed pleural biopsy (if needed) were conducted and all of them were inconclusive. The semirigid thoracoscopy (pleuroscopy) was performed for all patients for diagnostic purposes. Results: Eighty-seven percent of the peluroscopies were diagnostic and 67% of them were diagnosed as malignancy while the rest were diagnosed as tuberculosis. Only 11 patients developed minor complications. Conclusion: In conclusion, pleuroscopy is a safe procedure when performed by a skilled and experienced practitioner; it has a high diagnostic yield and results in only minor complications.

    The aim of this study was to find an ultrasonographic method to estimate pleural fluid volume in dogs. Nine canine cadavers of mixed breed were studied. Using a transsternal view, linear measurements from the pleural surface of the midline of the sternebra at the center of the heart to the furthest ventrolateral point of both right and left lung edges were recorded. Isotonic saline was injected using ultrasound guidance into both right and left pleural spaces and the measurements were repeated using standard increments until 1000 ml total volume was reached. No relationship was identified between mean distance and injected volume up to 100 ml. Thereafter, the mean distance increased in an approximately linear relationship with the cube root of fluid volume. There was a high correlation (r > or = 0.899) between the ultrasonographic measurement and fluid volume within individual dogs, but it was not possible to produce a useful equation to calculate absolute pleural fluid volume for new subjects. Nevertheless, ultrasonography may be used to semiquantitatively monitor pleural fluid volume, so that a decrease in the mean linear measurement obtained reflects a decrease in the total fluid volume.

    Abstract Context US EPA proposed a Reference Concentration for Libby amphibole asbestos based on the premise that pleural plaques are adverse and cause lung function deficits. Objective We conducted a systematic review to evaluate whether there is an association between pleural plaques and lung function and ascertain whether results were dependent on the method used to identify plaques. Methods Using the PubMed database, we identified studies that evaluated pleural plaques and lung function. We assessed each study for quality, then integrated evidence and assessed associations based on the Bradford Hill guidelines. We also compared the results of HRCT studies to those of X-ray studies. Results We identified 16 HRCT and 36 X-ray studies. We rated six HRCT and 16 X-ray studies as higher quality based on a risk-of-bias analysis. Half of the higher quality studies reported small but statistically significant mean lung function decrements associated with plaques. None of the differences were clinically significant. Many studies had limitations, such as inappropriate controls and/or insufficient adjustment for confounders. There was little consistency in the direction of effect for the most commonly reported measurements. X-ray results were more variable than HRCT results. Pleural plaques were not associated with changes in lung function over time in longitudinal studies. Conclusion The weight of evidence indicates that pleural plaques do not impact lung function. Observed associations are most likely due to unidentified abnormalities or other factors. PMID:25518994

    Of the 1.5 million people diagnosed with pleural effusion in the USA annually, ~178 000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied.This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was performed to obtain baseline characteristics. The aetiology of the effusions was determined using standardised criteria. Mortality was determined at 30 days and 1 year.247 unilateral and 61 bilateral thoracenteses were performed. Malignant effusion had the highest 30-day (37%) and 1-year (77%) mortality. There was substantial patient 30-day and 1-year mortality with effusions due to multiple benign aetiologies (29% and 55%), congestive heart failure (22% and 53%), and renal failure (14% and 57%, respectively). Patients with bilateral, relative to unilateral, pleural effusion were associated with higher risk of death at 30 days and 1 year (17% versus 47% (hazard ratio (HR) 2.58, 95% CI 1.44-4.63) and 36% versus 69% (HR 2.32, 95% CI 1.55-3.48), respectively).Patients undergoing thoracentesis for pleural effusion have high short- and long-term mortality. Patients with malignant effusion had the highest mortality followed by multiple benign aetiologies, congestive heart failure and renal failure. Bilateral pleural effusion is distinctly associated with high mortality. PMID:25837039

    2015-01-01

    Pleural disease is frequently encountered by the chest physician. Pleural effusions arise as the sequelae of underlying disease processes including pressure/volume imbalances, infection and malignancy. In addition to pleural effusions, persistent air leaks after surgery and bronchopleural fistulae remain a challenge. Our understanding of pleural disease including its diagnosis and management, have made tremendous strides. The introduction of the molecular detection of organism specific infection, risk stratification and improvements in the non-surgical treatment of patients with pleural infection are all within reach and may be the standard of care in the very near future. Malignant pleural effusion management continues to evolve with the introduction of tunneled pleural catheters and procedures combining that and chemical pleurodesis. These advances in the diagnostic and therapeutic evaluation of pleural disease as well as what seems to be an increasing multidisciplinary interest in the space foretell a bright future.

    The authors made a retrospective analysis of 51 patients with non-small-cell lung cancer with pleural effusion, not associated with tumor lesion of pleural leaves. Out of 51 operated patients 45 (88%) proved to be resectable. Among 45 patients (20 pneumonectomies, 24 lobectomies and 1 bilobectomy) combined interventions were fulfilled in 15 patients. In 27 (60%) out of 45 patients there was an injury of mediastinal lymph nodes, in 13 (29%)--intrapulmonary and root nodes. Complicated course of the postoperative period was noted in 27% of patients, lethality was 2%. One year survival after resection was 86%, three and five year survival was 54% and 30% respectively. The indices of survival reliably depended on the degree of lymphogenic dissemination. The presence of pleural effusion can not be a reason for refusal to fulfill radical surgical intervention.

    We reviewed the outcome of guided percutaneous catheter drainage of pleural fluid collections in 18 patients over a 5-year period. Catheter positioning was guided by fluoroscopy in 10 (56%) cases, CT in seven (39%), and sonography in one (6%). Included were 16 patients with empyemas and one each with a sterile hematoma and transudate. In nine of the patients, previous surgical chest tube drainage had been unsuccessful. The majority of collections were treated with a 12- or 14-French catheter and closed underwater seal drainage. Twelve (80%) of the 15 patients who had an adequate trial of guided drainage were cured. Propyliodone oil suspension contrast sinography after catheter placement showed two clinically unsuspected bronchopleural fistulas. Although an extensive multilocular pleural collection was a contraindication to percutaneous catheter drainage, the thick fibrous peel of a chronic empyema was not. Drainage of pleural fluid collections with radiographic guidance ensures proper catheter placement and is successful in a high percentage of cases. PMID:3055887

    Pleural biomarkers allowing to mini-invasively discriminate benign from malignant pleural effusions are needed. Among potential candidates, microparticles (MPs) are extracellular vesicles that vectorize antigen derived from the parent cell. We hypothesized that tumor-derived MPs could be present in the pleural liquid and help to identify patients with malignant pleural effusions. Using highly sensitive flow cytometry and cryo-electron microscopy, we showed that large amounts of MPs from hematopoïetic and vascular origin could be detectable in pleural fluids. Their level did not differ between benign (n = 14) and malignant (n = 71) pleural effusions. Analysis of selected tumoral associated antigens (podoplanin, mucin 1 and EpCAM, epithelial-cell-adhesion-molecule) evidenced for the first time the presence of tumor-derived MPs expressing EpCAM in malignant pleural fluids only (Specificity = 93%, Sensitivity = 49% and 45% for flow cytometry and ELISA, respectively). The detection of EpCAM-positive-MPs (EpCAM + MPs) by flow cytometry showed a better specificity and sensitivity than ELISA to distinguish between pleural carcinoma and the others malignant pleural effusions (MPE; Sp: 96% vs 89%; Se: 79% vs 66%). Combining EpCAM+ MPs and cytology improved the diagnosis of MPE compared to cytology alone. This study establishes the basis for using EpCAM+ MPs as a promising new biomarker that could be added to the armamentarium to mini-invasively identify patients with malignant pleural effusions.

The detection of EpCAM-positive-MPs (EpCAM + MPs) by flow cytometry showed a better specificity and sensitivity than ELISA to distinguish between pleural carcinoma and the others malignant pleural effusions (MPE; Sp: 96% vs 89%; Se: 79% vs 66%). Combining EpCAM+ MPs and cytology improved the diagnosis of MPE compared to cytology alone. This study establishes the basis for using EpCAM+ MPs as a promising new biomarker that could be added to the armamentarium to mini-invasively identify patients with malignant pleural effusions.

    Multiple myeloma is a clonal B-cell malignancy, characterised by proliferation of plasma cells and secretion of paraproteins. These plasma cells accumulate predominantly in the bone marrow; rarely, they invade other areas, especially the thorax. Myeloma presenting with a pleural effusion is rare and reported in only 6% of patients with myeloma. Such patients generally present late and have a poor prognosis. Here, we describe a patient presenting with a lung mass, renal failure and a massive unilateral pleural effusion due to multiple myeloma who was treated successfully. PMID:27520995

    We present the case of thoracic aortic aneurysm associated with the tuberculous pleural effusion. An 82-year-old woman underwent emergency stent graft under a diagnosis of dissecting thoracic aortic aneurysm. Preoperative computed tomography revealed right pleural effusion supposed to the hemothorax caused by the dissecting aneurysm. But, the effusion was sanguineous color fluid and it was determined to result from pulmonary tuberculosis. The medical team was exposed to the pulmonary tuberculosis; fortunately no one became infected. Physicians should be aware of the possibility of an infected aortic aneurysm and prepare for pathogen transmission. PMID:27499987

    Visceral leishmaniasis (VL) is usually characterized by splenomegaly, pallor and fever. Pleural effusion is an uncommon feature of this disease, which is encountered in immunocompromised patients. Here, we report a case of VL with pleural effusion in an immunocompetent patient. Pulmonary symptoms in VL are usually related to bacterial lung infection, vagal nerve compression by splenomegaly, and hypoalbuminaemia with mild pulmonary edema. Our patient presented with cough and chest pain. The clinical features of this case were baffling since they mimicked that of pulmonary tuberculosis. This case report emphasizes the need to recognize the diverse nature of presentation of this curable yet fatal infectious disease. PMID:24669085

    We herein report the case of a 61-year-old Japanese male with localized pleural metastases of renal cell carcinoma. The patient was admitted to our hospital because of dyspnea on exertion and left-sided pleural effusion. He had undergone right radical nephrectomy 10 years previously. Contrast-enhanced whole-body computed tomography revealed scattered nodular thickening of the left pleura with contrast enhancement and left-sided pleural effusion. Thoracoscopy performed under local anesthesia was applied to obtain a biopsy of the pleural nodules, and the specimen was consequently diagnosed as exhibiting pleural metastasis of renal cell carcinoma, clear cell type.

    The variety of strategies in the treatment of parapneumonic pleural empyema demonstrates the ambiguity for the method of choice. Parapneumonic pleural empyema has been classified into different stages and classes. While the American Thoracic Society (ATS) classification is based on the natural course of the disease, or according to the radiological, physical and biochemical characteristics respectively, the American College of Chest Physicians (ACCP) has categorized the patients with pleural empyema according to the risk of a poor outcome. The British Thoracic Society (BTS) developed a treatment algorithm based on a systematic review of peer-reviewed literature. With regard to this classification the management of parapneumonic and postoperative pleural empyema is based on the stage of the disease. Therapeutic strategies include chest tube alone, chest tube with fibrinolysis, thoracoscopic debridement and decortication in open or minimally invasive techniques, closed empyemectomy, or treatment with thoracomyoplasty, open window treatment or vacuum clothing with negative pressure. The different conservative and operative therapeutic possibilities determinate the central treatment function of thoracic surgery. PMID:23807591

    A sudden increase in pleural pressure such as coughing or a valsalva maneuver causes a transient increase in left ventricular stroke volume but the mechanism is not known. To help understand this phenomenon we studied 7 normal volunteers during spontaneous breathing and when breathing under positive pleural pressure. The positive pressure was developed by expiring against a 24cm H/sub 2/O threshold load. Radionuclide ventriculopgraphy using a double gating technique as performed. Image data were acquired during the cardiac cycles occurring during positive pleural pressure by means of a pressure transducer coupled to an EKG gate. They were compared to data acquired by EKG gating alone under quiet respiration as control. Results are shown for end diastolic (EDC), end systolic (ESC) and stroke counts (SC) and are expressed as % change from control for each parameter. The authors conclude that a transient increase in positive pleural pressure comparable to that reached during forceful coughing increases stroke volume and cardiac output through a combination of increased end diastolic volume with a lesser increase in end systolic volume. This effect was seen in the absence of any change in cardiac rhythm or rate.

    The growing utilisation of indwelling pleural catheters (IPCs) has put forward a new era in the management of recurrent symptomatic pleural effusions. IPC use is safe compared to talc pleurodesis, though complications can occur. Pleural infection affects <5% of patients, and is usually responsive to antibiotic treatment without requiring catheter removal or surgery. Pleural loculations develop over time, limiting drainage in 10% of patients, which can be improved with intrapleural fibrinolytic therapy. Catheter tract metastasis can occur with most tumours but is more common in mesothelioma. The metastases usually respond to analgaesics and/or external radiotherapy. Long-term intermittent drainage of exudative effusions or chylothorax can potentially lead to loss of nutrients, though no data exist on any clinical impact. Fibrin clots within the catheter lumen can result in blockage. Chest pain following IPC insertion is often mild, and adjustments in analgaesics and drainage practice are usually all that are required. As clinical experience with the use of IPC accumulates, the profile and natural course of complications are increasingly described. We aim to summarise the available literature on IPC-related complications and the evidence to support specific strategies. PMID:26870384

  18. Use of anabolic-androgenic steroids masking the diagnosis of pleural tuberculosis: a case report

    PubMed Central

    2009-01-01

    Introduction Tuberculous pleural effusions are not always easy to diagnose but the presence of a lymphocyte-rich exudate associated with an increased adenosine deaminase level and a positive skin test result are highly sensitive diagnostic signs. Case presentation We report a case of pleural tuberculosis in a 31-year-old white male patient from Caracas, Venezuela who was negative for human immunodeficiency virus and presented 2 weeks after injecting the anabolic-androgenic steroid nandrolone decanoate, in whom all the tests for tuberculosis were initially negative; an eosinophilic pleural effusion with a low adenosine deaminase level, a negative tuberculin skin test and negative for acid-fast bacilli staining and culture of the pleural fluid. After excluding other causes of eosinophilic pleural effusion malignant pleural effusion was suspected. The patient did not return until 4 months later. The second thoracentesis obtained a pleural fluid suggestive for tuberculosis, with a predominance of lymphocytes, an elevated adenosine deaminase level (51 U/l) and a positive tuberculin skin test. Culture of pleural fragments confirmed pleural tuberculosis. Conclusion This case suggests that the use of an anabolic-androgenic steroid masks the definitive diagnosis of pleural tuberculosis by changing the key diagnostic parameters of the pleural fluid, a finding not previously reported. Available evidence of the effects of anabolic steroids on the immune system also suggests that patients using anabolic-androgenic steroids might be susceptible to developing tuberculosis in either reactivating a latent infection or facilitating development of the disease after a recent infection.

    Pleural infection is a frequent clinical condition. Prompt treatment has been shown to reduce hospital costs, morbidity and mortality. Recent advances in treatment have been variably implemented in clinical practice. This statement reviews the latest developments and concepts to improve clinical management and stimulate further research. The European Association for Cardio-Thoracic Surgery (EACTS) Thoracic Domain and the EACTS Pleural Diseases Working Group established a team of thoracic surgeons to produce a comprehensive review of available scientific evidence with the aim to cover all aspects of surgical practice related to its treatment, in particular focusing on: surgical treatment of empyema in adults; surgical treatment of empyema in children; and surgical treatment of post-pneumonectomy empyema (PPE). In the management of Stage 1 empyema, prompt pleural space chest tube drainage is required. In patients with Stage 2 or 3 empyema who are fit enough to undergo an operative procedure, there is a demonstrated benefit of surgical debridement or decortication [possibly by video-assisted thoracoscopic surgery (VATS)] over tube thoracostomy alone in terms of treatment success and reduction in hospital stay. In children, a primary operative approach is an effective management strategy, associated with a lower mortality rate and a reduction of tube thoracostomy duration, length of antibiotic therapy, reintervention rate and hospital stay. Intrapleural fibrinolytic therapy is a reasonable alternative to primary operative management. Uncomplicated PPE [without bronchopleural fistula (BPF)] can be effectively managed with minimally invasive techniques, including fenestration, pleural space irrigation and VATS debridement. PPE associated with BPF can be effectively managed with individualized open surgical techniques, including direct repair, myoplastic and thoracoplastic techniques. Intrathoracic vacuum-assisted closure may be considered as an adjunct to the standard

    INTRODUCTION AND OBJECTIVES Tuberculosis and cancer are the main causes of pleural effusion. Pleural involvement is associated with migration of immune cells to the pleural cavity. We sought to characterize the immunophenotype of leukocytes in the pleural effusion and peripheral blood of patients with tuberculosis or malignancy. METHODS Thirty patients with tuberculosis (14) or malignancy (16) were studied. A control group included 20 healthy blood donors. RESULTS Malignant phycoerythrin pleural effusions showed higher percentages of CD3, CD4, CD3CD45RO, and CD20CD25 lymphocytes and lower percentages of CD3CD25 and CD20HLA-DR when compared to PB lymphocytes. Compared to PB, tuberculous effusions had a higher percentage of lymphocytes that co-expressed CD3, CD4, CD3CD45RO, CD3TCRαβ, CD3CD28, and CD20 and a lower percentage of CD14, CD8 and CD3TCRγδ-positive lymphocytes. Malignant effusions presented higher expression of CD14 whereas tuberculous effusions had higher expression of CD3 and CD3CD95L. Peripheral blood cells from tuberculosis patients showed higher expression of CD14, CD20CD25 and CD3CD95L. Compared with the control cells, tuberculosis and cancer peripheral blood cells presented a lower percentage of CD3CD4 and CD3CD28-positive cells as well as a higher percentage of CD3CD8, CD3CD25 and CD3CD80-positive cells. CONCLUSIONS Tuberculous and malignant peripheral blood is enriched with lymphocytes with a helper/inducer T cell phenotype, which are mainly of memory cells. CD14-positive cells were more frequently found in malignant effusions, while CD3-positive cells expressing Fas ligand were more frequently found in tuberculous effusions. PMID:18925324

    CYFRA 21-1 assay, measuring cytokeratin 19 fragments, was compared with carcinoembryonic antigen (CEA) assay, as an addition to cytological analysis for the diagnosis of malignant effusions. Both markers were determined with commercial enzyme immunoassays in pleural fluid from 196 patients. Cytological analysis and/or pleural biopsy confirmed the malignant origin of the effusion in 99 patients (76 carcinomas, nine pleural mesotheliomas and 14 non-epithelial malignancies). Effusions were confirmed as benign in 97 patients (33 cardiac failures, 39 infectious diseases--including 12 tuberculosis-- and 25 miscellaneous effusions). Both markers were significantly higher in malignant than in benign effusions. All the patients with non-epithelial malignancies presented CYFRA and CEA values lower than the 95% diagnostic specificity thresholds (100 and 6 ng ml(-1) respectively). The diagnostic sensitivity in the group of carcinomas and mesotheliomas was similar for CYFRA (58.8%) and CEA (64.7%). However, CEA had a significantly higher sensitivity in carcinomas (72.4% vs 55.3%), while CYFRA had a clearly higher sensitivity in mesotheliomas (89.9% vs 0%). Interestingly, 12 out of the 16 malignant effusions with a negative cytology were CEA and/or CYFRA positive. Regarding their high diagnostic sensitivity and their complementarity, CEA and CYFRA appear to be very useful for the diagnosis of malignant pleural effusions when cytology is negative.

    Introduction Pleural effusion is a common clinical problem that can complicate many medical conditions. Breathlessness is the most common symptom of pleural effusion of any cause and the most common reason for pleural drainage. However, improvement in breathlessness following drainage of an effusion is variable; some patients experience either no benefit or a worsening of their breathlessness. The physiological mechanisms underlying breathlessness in patients with a pleural effusion are unclear and likely to be multifactorial with patient-related and effusion-related factors contributing. A comprehensive study of the physiological and symptom responses to drainage of pleural effusions may provide a clearer understanding of these mechanisms, and may identify predictors of benefit from drainage. The ability to identify those patients whose breathlessness will (or will not) improve after pleural fluid drainage can help avoid unnecessary pleural drainage procedures, their associated morbidities and costs. The PLeural Effusion And Symptom Evaluation (PLEASE) study is a prospective study to comprehensively evaluate factors contributing to pleural effusion-related breathlessness. Methods and analysis The PLEASE study is a single-centre prospective study of 150 patients with symptomatic pleural effusions that require therapeutic drainage. The study aims to identify key factors that underlie breathlessness in patients with pleural effusions and develop predictors of improvement in breathlessness following effusion drainage. Participants will undergo evaluation pre-effusion and post-effusion drainage to assess their level of breathlessness at rest and during exercise, respiratory and other physiological responses as well as respiratory muscle mechanics. Pre-drainage and post-drainage parameters will be collected and compared to identify the key factors and mechanisms that correlate with improvement in breathlessness.

    IL-17-producing CD8(+) T lymphocytes (Tc17 cells) have recently been detected in many cancers and autoimmune diseases. However, the possible implication of Tc17 cells in tuberculous pleural effusion remains unclarified. In this study, distribution and phenotypic features of Tc17 cells in both tuberculous pleural effusion (TPE) and peripheral blood from patients with tuberculosis were determined. The effects of proinflammatory cytokines and local accessory cells (pleural mesothelial cells) on Tc17 cell expansion were also explored. We found that TPE contained more Tc17 cells than the blood. Compared with IFN-γ-producing CD8(+) T cells, Tc17 cells displayed higher expression of chemokine receptors (CCRs) and lower expression of cytotoxic molecules. In particularly, Tc17 cells in TPE exhibited high expression levels of CCR6, which could migrate in response to CCL20. Furthermore, IL-1β, IL-6, IL-23, or their various combinations could promote Tc17 cell expansion from CD8(+) T cells, whereas the proliferative response of Tc17 cells to above cytokines was lower than that of Th17 cells. Pleural mesothelial cells (PMCs) were able to stimulate Tc17 cell expansion via cell contact in an IL-1β/IL-6/IL-23 independent fashion. Thus this study demonstrates that Tc17 cells marks a subset of non-cytotoxic, CCR6(+) CD8(+) T lymphocytes with low proliferative capacity. The overrepresentation of Tc17 cells in TPE may be due to Tc17 cell expansion stimulated by pleural proinflammatory cytokines and to recruitment of Tc17 cells from peripheral blood. Additionally, PMCs may promote the production of IL-17 by CD8(+) T cells at sites of TPE via cell-cell interactions. PMID:23299924

    Abstract We investigated the role of F-18 fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) for the differential diagnosis of malignant and benign pleural effusion. We studied 36 consecutive patients with histologically proven cancer (excluding malignant mesothelioma) who underwent FDG-PET/CT for suspected malignant pleural effusion. Fourteen patients had cytologically proven malignant pleural effusion and the other 22 patients had either negative cytology or clinical follow-up, which confirmed the benign etiology. We examined the maximum standardized uptake values (SUVmax) of pleural effusion and the target-to-normal tissue ratio (TNR), calculated as the ratio of the pleural effusion SUVmax to the SUVmean of the normal tissues (liver, spleen, 12th thoracic vertebrae [Th12], thoracic aorta, and spinalis muscle). We also examined the size and density (in Hounsfield units) of the pleural effusion and pleural abnormalities on CT images. TNR (Th12) and increased pleural FDG uptake compared to background blood pool were significantly more frequent in cases with malignant pleural effusion (P < 0.05 for both). The cutoff TNR (Th12) value of >0.95 was the most accurate; the sensitivity, specificity, and accuracy for this value were 93%, 68%, and 75%, respectively. FDG-PET/CT can be a useful method for the differential diagnosis of malignant and benign pleural effusion. PMID:26200610

    The aim of this study was to investigate the association between image characteristics on preoperative chest CT and severe pleural adhesion during surgery in lung cancer patients. We included consecutive 124 patients who underwent lung cancer surgeries. Preoperative chest CT was retrospectively reviewed to assess pleural thickening or calcification, pulmonary calcified nodules, active pulmonary inflammation, extent of emphysema, interstitial pneumonitis, and bronchiectasis in the operated thorax. The extent of pleural thickening or calcification was visually estimated and categorized into two groups: localized and diffuse. We measured total size of pulmonary calcified nodules. The extent of emphysema, interstitial pneumonitis, and bronchiectasis was also evaluated with a visual scoring system. The occurrence of severe pleural adhesion during lung cancer surgery was retrospectively investigated from the electrical medical records. We performed logistic regression analysis to determine the association of image characteristic on chest CT with severe pleural adhesion. Localized pleural thickening was found in 8 patients (6.5%), localized pleural calcification in 8 (6.5%), pulmonary calcified nodules in 28 (22.6%), and active pulmonary inflammation in 22 (17.7%). There was no patient with diffuse pleural thickening or calcification in this study. Trivial, mild, and moderate emphysema was found in 31 (25.0%), 21 (16.9%), and 12 (9.7%) patients, respectively. Severe pleural adhesion was found in 31 (25.0%) patients. The association of localized pleural thickening or calcification on CT with severe pleural adhesion was not found (P = 0.405 and 0.107, respectively). Size of pulmonary calcified nodules and extent of emphysema were significant variables in a univariate analysis (P = 0.045 and 0.005, respectively). In a multivariate analysis, moderate emphysema was significantly associated with severe pleural adhesion (odds ratio of 11.202, P = 0.001). In conclusion, severe

    A 78-year-old woman complained of twisting-like pain in her left lower chest. During physical examination, friction rubbing was noted in both lungs. Chest radiography showed extensive bilateral pleural calcification. High-resolution computed tomography confirmed the presence of bilateral calcified pleural plaques. The patient had worked at a Japanese asbestos factory in Taiwan for 1 year when she was 16 years old. Her job involved picking out asbestos fibers from crushed asbestos minerals, but no protective equipment was used at that time. This is believed to be the first reported case of asbestos-related disease in Taiwan that resulted from asbestos mining. We also summarize the history of domestic asbestos mining, importation of asbestos, and trends in asbestos use in Taiwan. PMID:21195893

    Pleural effusion, secondary to a metastasis from a malignant hepatoblastoma, was diagnosed in a 3-year-old Appaloosa gelding. Severe hemorrhagic transudate in both pleural cavities resulted in acute onset of labored breathing, tachypnea, tachycardia, and jugular vein pulsation. Results of ultrasonography and radiography of the ventral lung field and cranial portion of the abdomen initially were nondiagnostic, as were results of cytologic examination of peritoneal fluid and tracheal wash specimens. Moderately high serum gamma-glutamyl transferase and alkaline phosphatase activities, despite normal hepatocyte-specific enzyme (sorbital dehydrogenase) activity, were indicative of biliary stasis without hepatocyte destruction. The horse was euthanatized. Necropsy revealed a 47-kg hepatoblastoma, with metastases in the lungs and intestines. PMID:2537279

    Background Prolonged air leak is the major cause of morbidity after pulmonary resection. In this study we used in vitro and in vivo experiments to investigate an innovative approach based on the use of human umbilical cord blood platelet gel. Materials and methods In vitro, a scratch assay was performed to test the tissue repair capability mediated by cord blood platelet gel compared to the standard culture conditions using human primary mesothelial cells. In vivo, an iatrogenic injury was made to the left lung of 54 Wistar rats. Cord blood platelet gel was placed on the injured area only in treated animals and at different times histological changes and the presence of pleural adhesions were evaluated. In addition, changes in the pattern of soluble inflammatory factors were investigated using a multiplex proteome array. Results In vitro, mesothelial cell damage was repaired in a shorter time by cord blood platelet gel than in the control condition (24 versus 35 hours, respectively). In vivo, formation of new mesothelial tissue and complete tissue recovery were observed at 45±1 and 75±1 hours in treated animals and at 130±2.5 and 160±6 hours in controls, respectively. Pleural adhesions were evident in 43% of treated animals compared to 17% of controls. No complications were observed. Interestingly, some crucial soluble factors involved in inflammation were significantly reduced in treated animals. Discussion Cord blood platelet gel accelerates the repair of pleural damage and stimulates the development of pleural adhesions. Both properties could be particularly useful in the management of prolonged air leak, and to reduce inflammation. PMID:23736928

    Pleural effusions are resistant to standard therapy, which causes discomfort and can require prolonged hospitalization. As an alternative, pleuroperitoneal shunting for pleural effusions of various etiologies was evaluated. We implanted 36 shunts in 29 patients. Two patients had bilateral shunts and five had shunt revisions. The effusion was related to a malignancy in 22 patients, postoperative chylothorax in two patients, and other causes in five patients. Therapeutic thoracentesis had been attempted in 28 patients, and eight had had chest tube placement previously with attempted sclerosis. Seven patients had a trapped lung syndrome. There was no operative mortality. All patients were deemed ready for discharge from the hospital if they had recovered from the operation within 48 hours. Five patients had poor results, either because of a moribund status or their refusal or inability to pump the shunt. Of the remaining 24 patients, four had good results with temporary improvement, and excellent results were achieved in 20 patients (83.3%), who experienced symptomatic relief and stabilization or regression of pleural effusion until the time of their death. Patients with chylothorax experienced complete resolution. The 14 patients with malignant effusions had a median survival of 4 months, and there were no instances of peritoneal tumor seeding. In conclusion, pleuroperitoneal shunting is an alternative therapy for pleural effusions that requires a limited hospitalization only, is associated with minimal and short-term discomfort, achieves excellent results in properly selected patients, and is the only viable therapy when lung expansion cannot be achieved.

    Tuberculous pleuritis is a common manifestation of extrapulmonary tuberculosis and is the most common cause of pleural effusion in many countries. Conventional diagnostic tests, such as microscopic examination of the pleural fluid, biochemical tests, culture of pleural fluid, sputum or pleural tissue, and histopathological examination of pleural tissue, have known limitations. Due to these limitations, newer and more rapid diagnostic tests have been evaluated. In this review, the authors provide an overview of the performance of new diagnostic tests, including markers of specific and nonspecific immune response, nucleic acid amplification and detection, and predictive models based on combinations of markers. Directions for future development and evaluation of novel assays and biomarkers for pleural tuberculosis are also suggested. PMID:18448504

    The diagnosis of pleural tuberculosis continues to be a challenge due to the low sensitivity of traditional diagnostic methods. Better and more rapid tests are needed for diagnosis of pleural TB. In this study, pleural fluids were tested with rapid test to determine Mycobacterium tuberculosis (MTB antigen). Affinity chromatography was used to purify specific polyclonal antibodies against MTB antigen. Pleural samples after decontamination were treated with proteinase K. Rapid test for pleural fluids was prepared by specific antibody. Rapid test was performed on 85 pleural fluid patients. The patients had a mean age of 46.55 ± 15.96 years and 38 were men. The performance of rapid test, using proteinase K, was found to be the most impressive: sensitivity 93%, specificity 94%, PPV 90%, and NPV 96% compared with adenosine deaminase test (ADA), PCR, smear, and culture. The present study did demonstrate that modified TB rapid test can substantially improve the diagnosis of extrapulmonary TB. PMID:26693840

    The acquisition of histologic material is obligatory in order to establish the diagnosis of malignant pleural mesothelioma (MPM). In particular, tissue acquisition in cases of "dry" MPM (focal pleural thickening without pleural effusion or mediastinal lymph node involvement) is usually performed via a thoracoscopic pleural biopsy. In contrast, the techniques for performing echoendoscopic (transbronchial or transesophageal) needle aspiration of pleural lesions have only rarely been reported due to the theoretical limitations of tissue acquisition in such cases. We herein report the first case of "dry" MPM successfully diagnosed via endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in a 73-year-old man presenting with a pleural mass in the right costovertebral recess, adjacent to the carina. The patient underwent radical resection, and a definitive pathological examination confirmed the diagnosis of epithelioid MPM. PMID:24583437

    Malignant pleural mesothelioma is a rare and aggressive malignancy of the pleura correlated with exposure to asbestos, with a medium survival of 11–12 months after diagnosis. A case of a 67-year-old male who had previously worked in the asbestos industry and is a current smoker is reported. The computed tomography evaluation revealed a right pleural mass with pleural thickening, and the pleural biopsy confirmed a diagnosis of malignant pleural mesothelioma. He was treated with chemotherapy consisting of etoposide, paclitaxel, and pegylated liposomal doxorubicin hydrochloride. After completion of chemotherapy, radiologic evaluation confirmed a reduction of pleural thickening and improvement in his symptoms. A complete presentation of each drug formulation and characteristics are also included in this paper. The patient’s follow-up is continuing, and computed tomography reveals stable disease 9 years after initial examination. PMID:23055748

    During a cross sectional medical survey of 2815 insulation workers with 30 years or more from onset of asbestos exposure conducted from 1981 to 1983, a positive history of benign pleural effusion was found in 20 (0.71%). Two or three such episodes had occurred in four of these 20 subjects. The chest x ray abnormalities in these cases were characterised by pleural fibrosis in 19 and diffuse pleural fibrosis with blunting of the corresponding costophrenic angle in 16. In the total group of 2815 insulation workers diffuse pleural fibrosis was found in 142 (5.0%). Thus diffuse pleural fibrosis with blunting of the corresponding costophrenic angle is a frequent residual abnormality after benign pleural effusion. Its impact on pulmonary function can be pronounced. Images PMID:3260799

    Localized malignant pleural mesothelioma (LMPM) is a rare tumor with good prognosis by surgical resection. We report an atypical case of malignant pleural sarcomatoid mesothelioma (SM) in an asymptomatic 65-year-old woman, who had no history of exposure to asbestos. She presented with a small pleural mass without pleural effusion and was misdiagnosed as a benign localized fibrous tumor (BLFT) on pathologic examination through a surgical tumor specimen. However, seven months later, the patient returned with serious cancerous symptoms. A large recurrent tumor mass was found within the chest wall invading at the old surgical resection site. SM, a subtype of LMPM, was confirmed with histopathogy and immunohistochemisty. In conclusion, malignant pleural mesothelioma (MPM) can present with typical radiologic finding similar to a BLFT, and has a wide histopathologic presentation in biopsy specimen. A thorough pathologic investigation should be attempted even when a pleural mass resembles benign, localized, and small on radiologic studies. PMID:27293862

    We used quantitative reflectance autoradiography to compare the concentration of albumin in visceral pleural lymphatics at the cranial and caudal ends of the sheep's lung in the vertical (60 degrees head-up) and horizontal (supine) positions. Twelve to fourteen hours after injecting 125I-albumin intravenously we placed four anesthetized sheep in the vertical position to establish a microvascular hydrostatic pressure gradient along the vertical height of the lung. We placed two anesthetized sheep in the horizontal position. Four hours later, we fixed the left lung and removed visceral pleural tissue blocks from the cranial and caudal ends, separated by a 15-cm distance, along the costovertebral margin. We measured the silver grain density in the pleural lymphatic autoradiograms by dark-field reflectance microspectrophotometry. In the vertical position, the lymph albumin concentration at the cranial end (top) of the lung averaged 2.5 +/- 0.4 g/dl compared with the caudal end (bottom), which averaged 1.8 +/- 0.3 g/dl. The difference (42% greater at the top than the bottom) is significant (P less than 0.05). The computed gradient in perimicrovascular interstitial albumin osmotic pressure was 0.26 +/- 0.13 cmH2O/cm lung height. There were no differences between the cranial and caudal lymphatic groups in the two horizontal sheep. We conclude that in the sheep lung there is a gradient in perimicrovascular albumin concentration due to the vertical gradient in microvascular hydrostatic pressure.

    For the differential diagnosis between fibrous pleuritis and other malignancies such as lung cancer, multiple immunostaining is essential to diagnose pleural mesothelioma. For cytological diagnosis of pleural effusions, differentiation between mesothelioma cells and reactive mesothelial cells is very difficult. Therefore, histological diagnoses of tumor tissues obtained via biopsy are essential. To diagnose epthelioid mesothelioma, more than 2 positive and negative markers must be consistent with those known for mesothelioma. To diagnose sarcomatoid mesothelioma, keratin is usually positive, differentiating the diagnosis from that for real sarcoma. For surgical treatment for pleural mesothelioma, extrapleural pneumonectomy (EPP) and pleurectomy/decortication (P/D) are usually performed. The proportion of P/D increases because of the low death rates with surgery and similar survivals. However, a trimodal approach, such as EPP with chemotherapy and radiotherapy, is best for longer survival and expected to be curative. For chemotherapy, only cisplatin (CDDP) combined with pemetrexed (PEM) is effective, and no other agents have been identified for this disease. Nowadays, clinical immunotherapy trials start with phase II study. PMID:27210080

    Malignant pleural effusion (MPE) can complicate most malignancies and is a common clinical problem presenting to respiratory and cancer care physicians. Despite its frequent occurrence, current knowledge of MPE remains limited and controversy surrounds almost every aspect in its diagnosis and management. A lack of robust data has led to significant practice variations worldwide, inefficiencies in healthcare provision, and threats to patient safety. Recent studies have highlighted evolving concepts in MPE care that challenge traditional beliefs. Advancing laboratory techniques have improved the diagnostic yield from pleural fluid cytology, minimizing the need for invasive tissue biopsies, even in many cases of mesothelioma. Imaging-guided biopsy is comparable to thoracoscopy in suitable patients, if cytological examination was noncontributory. Cumulating evidence for the benefits of indwelling pleural catheters (IPCs) has led some centers to adopt this approach as first-line definitive management for MPE over conventional talc pleurodesis. The optimal technique of talc pleurodesis is still debated despite its use for many decades. Strategies combining pleurodesis and IPC are being studied. MPE consists of a heterogenous group of diseases and careful phenotyping of malignant effusion patients can provide important clinical information that will advance the field and allow better stratification of patients and planning of therapy accordingly. This review addresses the controversies in MPE diagnosis and management and exposes the deficits in knowledge of MPE that should be the focus of future research. PMID:25463163

    This study examines the light fluence (rate) delivered to patients undergoing pleural PDT as a function of treatment time, treatment volume and surface area. The accuracy of treatment delivery is analyzed as a function of the calibration accuracies of each isotropic detector and the calibration integrating sphere. The patients studied here are enrolled in a Phase I clinical trial of HPPH-mediated PDT for the treatment of non-small cell lung cancer with pleural effusion. Patients are administered 4mg per kg body weight HPPH 24-48 hours before the surgery. Patients undergoing photodynamic therapy (PDT) are treated with light therapy with a fluence of 15-60 J/cm2 at 661nm. Fluence rate (mW/cm2) and cumulative fluence (J/cm2) is monitored at 7 different sites during the entire light treatment delivery. Isotropic detectors are used for in-vivo light dosimetry. The anisotropy of each isotropic detector was found to be within 15%. The mean fluence rate delivery and treatment time are recorded. A correlation between the treatment time and the treatment volume is established. The result can be used as a clinical guideline for future pleural PDT treatment.

    Pleural effusion is a known entity in patients undergoing allogeneic hematopoietic stem cell transplantation (HSCT); however, the incidence, risk factors, and morbidity-mortality outcomes associated with pleural effusions remain unknown. We retrospectively evaluated pleural effusions in 618 consecutive adult patients who underwent allogeneic HSCT from January 2008 to December 2013 at our institution. Seventy one patients developed pleural effusion at a median of 40 days (range, 1 - 869) post-HSCT with the cumulative incidence of 9.9% (95% CI, 7.7 - 12.5%) at 1 year. Infectious etiology was commonly associated with pleural effusions followed by volume overload and serositis type chronic GVHD. In multivariate analysis, higher comorbidity index (P = 0.03) and active GVHD (P = 0.018) were found to be significant independent predictors for pleural effusion development. Higher comorbidity index, very high disease risk index, ≤7/8 HLA matching, and unrelated donor were associated with inferior overall survival (OS) (P < 0.03). More importantly, patients with pleural effusion were noted to have poor OS in comparison to patients without pleural effusion (P < 0.001). Overall, pleural effusion is a frequently occurring complication after allogeneic HSCT, adding to morbidity and mortality and hence, early identification is required. Am. J.

    A 22-year-old Asian male presented with fever, non-productive cough, right-sided pleuritic chest pain and was found to have a large right hydropneumothorax. A chest tube was placed. Pleural fluid analysis revealed a lymphocytic predominant exudate and he was subsequently started on four-drug daily anti-tuberculosis therapy (isoniazid, ethambutol, rifampin, pyrazinamide). Pleural biopsy revealed acid-fast bacilli. Given his persistent pleural effusion, he was given four doses of intrapleural tissue plasminogen activator (tPA) and dornase alpha (DNase) via his chest tube over a period of 6 days resulting in clinical and radiologic improvement. Pleural biopsy and pleural fluid culture specimens later revealed Mycobacterium tuberculosis. Intrapleural tPA-DNase therapy has demonstrated improved resolution of infections and shortened hospitalizations for parapneumonic infectious effusions. However, there is little literature on the use of intrapleural fibrinolytics specifically for pleural tuberculosis associated effusions. Furthermore, the American Thoracic Society does not comment on therapeutic thoracentesis or intrapleural fibrinolytic therapy in their recommendations for treatment of pleural tuberculosis. In our case of pleural TB-associated hydropneumothorax, the use of intrapleural tPA-DNase therapy facilitated pleural fluid drainage and resulted in near-complete resolution of the effusion.

    BACKGROUND: The proportion of T and B lymphocytes in pleural fluids and blood may point to the presence of local immunological phenomena in pleural disorders. AIM: Aim of study was to evaluate the lymphocyte phenotype and the ratio between helper (CD4+) and cytotoxic/suppressor (CD8+) lymphocytes in malignant and non-malignant effusions. MATERIAL AND METHODS: We studied 48 patients with pleural effusions. First group had 18 patients with tuberculosis pleural effusions; second group had 20 patients with malignant pleural fluids, third group had 10 patients with transudates and 30 healthy controls. We investigated the distribution of T and B lymphocytes, T cells with helper/inducer CD4 or suppresser/cytotoxic CD8 phenotypes and the CD16 subset. RESULTS: Results showed decreases levels of CD3, CD4, and CD16 T cells in blood of patients versus healthy controls. There were increases in the percentage of the CD3 and CD4 T cells in the pleural fluid compared with values in the blood with statistical significance in tuberculous pleurisy. The values of CD8 were similar in the pleural fluid and in blood. Levels of CD16 were non-significantly higher in pleural fluid in all groups. CONCLUSION: This study confirms the hypothesis that pleural cavity is compartment with immunological reactivity and results could be used in differential diagnosis together with other examinations.

    The relationship between the occurrence of neoplastic diseases and the presence of pleural plaques was studied in a series of 1097 autopsies performed in Turin from the adult general population. In men, pleural plaques showed an association with the presence of laryngeal, pulmonary, esophageal, and colorectal cancer. Only cancer of the larynx was strongly related to the occurrence of such pleural changes. This autopsy investigation confirms previous observations by others based on x-ray findings, and suggests that pleural plaques may be regarded as risk indicators of possibly asbestos-related tumors in the general population.

    Background Vascular endothelial growth factor (VEGF) may play a role in pleural fluid formation, as it represents a potent inducer of capillary permeability. We aimed to investigate the diagnostic utility of VEGF levels in pleural fluid and serum in patients with pleural effusions with initially negative diagnostic work up. Methods Seventy-one patients with exudative lymphocytic pleural effusions undiagnosed after initial diagnostic work up were enrolled in this prospective study and their clinical course was followed up to 24 months. VEGF levels were measured in serum and pleural fluid by using immunoenzymometric assay. Results During the follow up period, in 43 patients the pleural effusion was eventually attributed to malignancy while in the rest 28 patients it was due to non-malignant causes (benign and unknown origin). Patients with malignancy had significantly higher VEGF levels in pleural fluid compared to patients with non-malignant effusions (1,506 vs. 588 pg/dL, P=0.0001), while no statistically significant difference was found in the VEGF serum levels between the two groups. Conclusions Pleural VEGF levels may be helpful in identifying malignant pleural effusion (MPE) in patients with negative diagnostic work up at the initial assessment and help in selecting patients for more invasive procedures.

    Malignant pleural mesothelioma (MPM) is an asbestos-related cancer with a median survival of 12months. The MPM incidence is 1-6/100,000 and is increasing as a result of historic asbestos exposure in industrialized countries and continued use of asbestos in developing countries. Lack of accurate biomarkers makes diagnosis, prognostication and treatment prediction of MPM challenging. The aim of this review is to identify the front line of MPM biomarkers with current or potential clinical impact. Literature search using the PubMed and PLoS One databases, the related-articles function of PubMed and the reference lists of associated publications until April 26th 2015 revealed a plethora of candidate biomarkers. The current gold standard of MPM diagnosis is a combination of two positive and two negative immunohistochemical markers in the epithelioid and biphasic type, but sarcomatous type do not have specific markers, making diagnosis more difficult. Mesothelin in serum and pleural fluid may serve as adjuvant diagnostic with high specificity but low sensitivity. Circulating proteomic and microRNA signatures, fibulin-3, tumor cell gene-ratio test, transcriptomic, lncRNA, glycopeptides, pleural fluid FISH assay, hyaluronate/N-ERC mesothelin and deformability cytometry may be important future markers. Putative predictive markers for pemetrexed-platinum are tumor TS and TYMS, for vinorelbine the ERCC1, beta-tubuline class III and BRCA1. Mutations of the BAP1 gene are potential markers of MPM susceptibility. In conclusion, the current status of MPM biomarkers is not satisfactory but encouraging as more sensitive and specific non-invasive markers are emerging. However, prospective validation is needed before clinical application. PMID:25979846

    In-vivo light dosimetry for patients undergoing photodynamic therapy (PDT) is critical for predicting PDT outcome. Patients in this study are enrolled in a Phase I clinical trial of HPPH-mediated PDT for the treatment of non-small cell lung cancer with pleural effusion. They are administered 4mg per kg body weight HPPH 48 hours before the surgery and receive light therapy with a fluence of 15-45 J/cm2 at 661 and 665nm. Fluence rate (mW/cm2) and cumulative fluence (J/cm2) are monitored at 7 sites during the light treatment delivery using isotropic detectors. Light fluence (rate) delivered to patients is examined as a function of treatment time, volume and surface area. In a previous study, a correlation between the treatment time and the treatment volume and surface area was established. However, we did not include the direct light and the effect of the shape of the pleural surface on the scattered light. A real-time infrared (IR) navigation system was used to separate the contribution from the direct light. An improved expression that accurately calculates the total fluence at the cavity wall as a function of light source location, cavity geometry and optical properties is determined based on theoretical and phantom studies. The theoretical study includes an expression for light fluence rate in an elliptical geometry instead of the spheroid geometry used previously. The calculated light fluence is compared to the measured fluence in patients of different cavity geometries and optical properties. The result can be used as a clinical guideline for future pleural PDT treatment.

    Background Fibroblast specific protein-1 (S100A4) is related with many fibrotic diseases, but its role in the pathogenesis of pleural fibrosis has not been fully elucidated. Then we aim to investigate the expression and effect of fibroblast specific protein-1 (S100A4) in pleural tuberculosis and, subsequently, pleural fibrosis. Methods The expression of S100A4 in pleura was examined in 30 patients with pleural tuberculosis and 5 control (disease-free) patients by immunohistochemistry using the streptavidin-peroxidase (S-P) conjugated method. Results The expression of S100A4 in pleura was mainly distributed in the nucleus and cytoplasm of fibroblasts and vascular endothelial cells, and the positive rate was 90.0% (27 out of 30 patients with pleural tuberculosis). There were no expressions of S100A4 in the control group. In the pleura of all 30 patients with pleural tuberculosis, S100A4 had a higher expression in the two- to eight-week duration of the disease. Conclusions S100A4 plays an important role in the phenotypic transformation of pleural mesothelial cells and the development of pleural fibrosis. PMID:24885536

    Renal lymphangiectasia is a disorder of the lymphatic system of the kidneys, which can be congenital or acquired. Although the exact etiology remains unknown, an obstructive process resulting from several causes, including infection, inflammation or malignant infiltration, has been suggested to be responsible for the acquired form. This disorder may be associated with several pathologies. We report a case of a 24-year-old man with renal lymphangiectasia presenting with polycythemia, ascites and pleural effusion associated with hepatitis C virus (HCV) infection in an intravenous (IV) drug user. Our case is the first in the literature that shows an association between HCV infection and IV drug use. PMID:26858768

    Air travel is contraindicated in patients with a pneumothorax but was necessary because of the exigencies of war in three patients. Three patients with high velocity missile injuries to the chest and pleural adhesions are reported. All had to be evacuated by air, without an intercostal drain or oxygen supplement, from the war stricken area of Northern Somalia (Horn of Africa) to Mogadishu. Two patients with a partial pneumothorax flew on military transport aeroplanes at an altitude of 3000 m in a non-pressurised cabin and recovered rapidly after a few days in hospital. One patient, transported on a small Cessna aeroplane, died after developing bilateral tension pneumothoraces. Images PMID:1481187

    The vast majority of teratomas originating from more than a single germ layer are benign. Often, such teratomas are initially asymptomatic. Later symptoms are caused by the weight per se of the teratoma and include chest pain, cough, dyspnea, and/or recurrent attacks of pneumonia. A mediastinal teratoma is treated by total surgical resection of the mass. Here, we report a case of giant mature cystic teratoma mimicking a pleural effusion in the thorax at the 7-month-old female patient with a symptom of persistent pulmonary infection and tachypnea.

    Malignant mesothelioma is a relatively uncommon malignancy. Although the pathogenesis is primarily related to asbestos, the role of ionizing radiation is more controversial. We report the case of a 41-year-old male who developed pleural mesothelioma. He had both, a prior short asbestos exposure and a thoracic radiotherapy for Hodgkin's disease 26years before. The evidence for radiotherapy as cause for mesothelioma is expanding and the diagnosis of mesothelioma in patients who had previous irradiation should be kept in mind. PMID:23796498

    Although pain and dyspnoea are common symptoms in pleural diseases, there are few studies on the sensory innervation of the pleura. Using rabbits, after removal of all muscles in the intercostal space to be studied, we investigated the afferents of the internal intercostal nerve by applying to the internal thoracic wall pieces of gauze soaked in warmed (37°C), buffered saline (mechanical stimulation) or solutions containing lactic acid, inflammatory mediators or capsaicin (chemical stimulation). The afferent conduction velocity ranged from 0.5 to 14 m s−1. Most units (97%) were activated by mechanical stimulation of the pleura (local positive pressure range = 4.5–8.5 cmH2O) and we found a linear relationship between the discharge rate of afferents and the force applied to the thoracic wall. The majority of mechanosensitive units (70%) also responded to one or several chemical agents. Thus, the afferents were activated by lactic acid (49%) and/or a mixture of inflammatory mediators (50%). Local application of capsaicin elicited an initial increased or decreased background afferent activity in 57% of the afferents, a delayed decrease in firing rate being noted in some units initially activated by capsaicin. Capsaicin blocked the afferent response to a further application of inflammatory mediators but did not affect the mechanosensitive units. Thus, sensory endings connected with thin myelinated and unmyelinated fibres in the internal intercostal nerve detect the mechanical and chemical events of pleural diseases. PMID:15975985

    Hydrothorax as a complication of peritoneal dialysis (PD) is a rare but recognized event. Proposed mechanisms for the development of a pleuro-peritoneal communication include congenital diaphragmatic defects, acquired weakening of diaphragmatic fibers caused by high intra-abdominal pressures during peritoneal dialysis, and impairments in lymphatic drainage. Pleural fluid analysis and diagnostic imaging assist in differentiation from other causes of pleural effusion. Nearly 50% of patients with this diagnosis have resolution of hydrothorax after temporary cessation of PD with interim hemodialysis for 2-6 weeks. Historically, other treatment options have included conventional pleurodesis and open thoracotomy with direct repair, producing variable results. With the advent of video-assisted thoracoscopy (VATS), surgical repairs and pleurodesis are now frequently performed under direct visualization with minimal invasiveness. We report a case of hydrothorax in a patient after recent introduction to peritoneal dialysis. Pleuro-peritoneal communication was documented with thoracentesis and radionuclide scanning. VATS pleurodesis with talc was performed. Repeat scintigraphy performed 1 week after the procedure revealed no residual communication, and patient was able to resume PD without further complications.

    This paper reports on an unusual case of pleural epitheloid mesothelioma in a nine-month-old male, mixed breed dog. The dog was presented in-extremis and, on post mortem examination, multiple, exophytic, frequently pedunculated, yellowish-red, soft to firm masses ranging from 3 mm to 6 cm in diameter were diffusely distributed over, and attached to, the pericardial and parietal pleural surfaces. Microscopically, these masses consisted of round to partially polygonalshaped, anaplastic cells with minimal cytoplasm and hyperchromatic nuclei covering papillomatous projections or as part of more densely cellular masses. A supporting fibrovascular stroma and mitotic figures were also evident. Constituent tumour cells were labeled positively with antibodies against both vimentin and cytokeratin. In contrast, the same cells exhibited equivocal labeling with an antibody directed against calretinin antigen and did not label with antibodies against carcinoembryonic antigen (CEA) and milk fat globule-related antigen (MFGRA). Such tumours are rare in dogs, particularly in such a young animal. PMID:21851687

    Pleural photodynamic therapy (PDT) has been used as an adjuvant treatment with lung-sparing surgical treatment for mesothelioma with remarkable results. In the current intrapleural PDT protocol, a moving fiber-based point source is used to deliver the light and the light dose are monitored by 7 detectors placed in the pleural cavity. To improve the delivery of light dose uniformity, an infrared (IR) camera system is used to track the motion of the light sources. A treatment planning system uses feedback from the detectors as well as the IR camera to update light fluence distribution in real-time, which is used to guide the light source motion for uniform light dose distribution. We have improved the GUI of the light dose calculation engine to provide real-time light fluence distribution suitable for guiding the surgery to delivery light more uniformly. A dual-correction method is used in the feedback system, so that fluence calculation can match detector readings using both direct and scatter light models. An improved measurement device is developed to automatically acquire laser position for the point source. Comparison of the effects of the guidance is presented in phantom study.

    Photodynamic therapy (PDT) is a form of non-ionizing radiation therapy that uses a drug, called a photosensitizer, combined with light to produce singlet oxygen ((1)O2) that can exert anti-cancer activity through apoptotic, necrotic, or autophagic tumor cell death. PDT is increasingly being used to treat thoracic malignancies. For early-stage non-small cell lung cancer (NSCLC), PDT is primarily employed as an endobronchial therapy to definitively treat endobronchial or roentgenographically occult tumors. Similarly, patients with multiple primary lung cancers may be definitively treated with PDT. For advanced or metastatic NSCLC and small cell lung cancer (SCLC), PDT is primarily employed to palliate symptoms from obstructing endobronchial lesions causing airway compromise or hemoptysis. PDT can be used in advanced NSCLC to attempt to increase operability or to reduce the extent of operation intervention required, and selectively to treat pleural dissemination intraoperatively following macroscopically complete surgical resection. Intraoperative PDT can be safely combined with macroscopically complete surgical resection and other treatment modalities for malignant pleural mesothelioma (MPM) to improve local control and prolong survival. This report reviews the mechanism of and rationale for using PDT to treat thoracic malignancies, details prospective and major retrospectives studies of PDT to treat NSCLC, SCLC, and MPM, and describes improvements in and future roles and directions of PDT.

    OBJECTIVES: Delay in the treatment of pleural infection may contribute to its high mortality. In this retrospective study, we aimed to evaluate the diagnostic accuracy of pleural adenosine deaminase in discrimination between Gram-negative and Gram-positive bacterial infections of the pleural space prior to selecting antibiotics. METHODS: A total of 76 patients were enrolled and grouped into subgroups according to Gram staining: 1) patients with Gram-negative bacterial infections, aged 53.2±18.6 years old, of whom 44.7% had empyemas and 2) patients with Gram-positive bacterial infections, aged 53.5±21.5 years old, of whom 63.1% had empyemas. The pleural effusion was sampled by thoracocentesis and then sent for adenosine deaminase testing, biochemical testing and microbiological culture. The Mann-Whitney U test was used to examine the differences in adenosine deaminase levels between the groups. Correlations between adenosine deaminase and specified variables were also quantified using Spearman’s correlation coefficient. Moreover, receiver operator characteristic analysis was performed to evaluate the diagnostic accuracy of pleural effusion adenosine deaminase. RESULTS: Mean pleural adenosine deaminase levels differed significantly between Gram-negative and Gram-positive bacterial infections of the pleural space (191.8±32.1 U/L vs 81.0±16.9 U/L, p<0.01). The area under the receiver operator characteristic curve was 0.689 (95% confidence interval: 0.570, 0.792, p<0.01) at the cutoff value of 86 U/L. Additionally, pleural adenosine deaminase had a sensitivity of 63.2% (46.0-78.2%); a specificity of 73.7% (56.9-86.6%); positive and negative likelihood ratios of 2.18 and 0.50, respectively; and positive and negative predictive values of 70.6% and 66.7%, respectively. CONCLUSIONS: Pleural effusion adenosine deaminase is a helpful alternative biomarker for early and quick discrimination of Gram-negative from Gram-positive bacterial infections of the pleural space

    Objective The present study investigated effect of using pump on postoperative pleural effusion in patients who underwent coronary artery bypass grafting. Methods A total of 256 patients who underwent isolated coronary artery bypass grafting surgery in the Cardiovascular Surgery clinic were enrolled in the study. Jostra-Cobe (Model 043213 105, VLC 865, Sweden) heart-lung machine was used in on-pump coronary artery bypass grafting. Off-pump coronary artery bypass grafting was performed using Octopus and Starfish. Proximal anastomoses to the aorta in both on-pump and off-pump techniques were performed by side clamps. The patients were discharged from the hospital between postoperative day 6 and day 11. Results The incidence of postoperative right pleural effusion and bilateral pleural effusion was found to be higher as a count in Group 1 (on-pump) as compared to Group 2 (off-pump). But the difference was not statistically significant [P>0.05 for right pleural effusion (P=0.893), P>0.05 for bilateral pleural effusion (P=0.780)]. Left pleural effusion was encountered to be lower in Group 2 (off-pump). The difference was found to be statistically significant (P<0.05, P=0.006). Conclusion Under the light of these results, it can be said that left pleural effusion is less prevalent in the patients that underwent off-pump coronary artery bypass grafting when compared to the patients that underwent on-pump coronary artery bypass grafting.

    A panel of tumour markers including carcinoembryonic antigen (CEA), carbohydrate antigen (Ca)15-3, Ca125 and Ca19-9 were measured in the lysate of sediments and in the supernatants of pleural effusions of patients with benign and malignant disease. The tumour markers were also measured in the serum of the same patients. Of these patients, 32 had benign diseases (12 trasudative effusions associated with cirrhosis and 20 with non-malignant exudates: 12 pleuritis and 8 other inflammations) and 103 had malignant effusions (37 breast cancers, 29 lung cancers, 10 ovary cancers, 6 kidney cancers, 11 mesotheliomas and 10 lymphomas). We showed the highest level of CEA in pleural effusions of lung cancer followed by that in pleural effusions of breast cancer; whereas Ca15-3 was very high in the pleural effusions of breast and lung cancer. Concerning the lysate of sediment, CEA was high in the pleural effusions of patients with lung cancer and Ca15-3 in those of patients with breast cancer. The other markers are much less useful. For the remaining tumours, none of the markers tested appear to aid in the diagnosis of disease. In conclusion, our data suggest that the combined determination of tumour markers on supernatants and sediments of pleural effusion may provide additional information on the nature of pleural effusion, especially for cases with negative cytology.

    Background Malignant pleural mesothelioma is a rare, invasive and often fatal neoplasm that develops in the thin layer of tissue surrounding the lungs known as the pleura. Although rare, mesotheliomas do occur in the young; their characteristics are distinct from those of older patients. Case presentation This is a case report of a 17-year-old boy who had moderate dyspnea, cough, right-sided pleuritic chest pain, fever, headache and no weight loss. Physical examination showed a right pleural effusion and chest roentgenograms revealed a homogenous opacity on lower right hemithorax. Biochemical analysis of pleural fluid showed hemorrhagic/turbid effusion compatible with exudate. It was initially treated as an empyema. The pleural fluid culture was negative. Adenosine deaminase level was 34.3 U/L (admission) and 19.02 U/L (two weeks after). Pleural fluid smear and culture for Mtb were negative. During the open pleural biopsy, thickened pleura and multiple pale yellow nodules in the lung were observed. The histopathological report was compatible with malignant pleural mesothelioma. With this diagnosis, a chemotherapy regimen with cisplatin was initiated. After two cycles, the patient had no clinical and radiological improvement. The patient is currently under regular follow up. Conclusion MPM is rare in young adults and its clinical presentation makes it different from mesothelioma in elderly patients, so it will be necessary to identify the new risk factors that can identify these patients.
