Background: Upper-lung field pulmonary fibrosis (upper-PF), radiologically consistent with pleuroparenchymal fibroelastosis (PPFE), was reported to develop in patients with a history of asbestos exposure and tuberculous pleurisy, indicating that chronic pleuritis is correlated with upper-PF development. Round atelectasis reportedly emerges after chronic pleuritis. This study aimed to clarify the association between round atelectasis and upper-PF., Methods: We examined the radiological reports of all consecutive patients with round atelectasis between 2006 and 2018 and investigated the incidence of upper-PF development., Results: Among 85 patients with round atelectasis, 21 patients (24.7%) were confirmed to finally develop upper-PF lesions. Upper-PF was diagnosed after round atelectasis recognition in more than half of the patients (13/21, 61.9%), whereas upper-PF and round atelectasis were simultaneously detected in the remaining 8 patients. At the time of round atelectasis detection, almost all patients (19/21, 90.5%) had diffuse pleural thickening and round atelectasis was commonly observed in non-upper lobes of 19 patients (90.5%). Fourteen patients had round atelectasis in unilateral lung, and the remaining 7 patients had round atelectasis in bilateral lungs. Among all 14 patients with unilateral round atelectasis, upper-PF developed on the same (n = 11) or both sides (n = 3). Thus, upper-PF emerged on the same side where round atelectasis was present (14/14, 100%). The autopsy of one patient revealed a thickened parietal-visceral pleura suggestive of chronic pleuritis. Subpleural fibroelastosis was also observed., Conclusions: Upper-PF occasionally develops on the same side of round atelectasis. Upper-PF may develop as a sequela of chronic pleuritis., Competing Interests: Conflict of Interest The authors have no conflicts of interest., (Copyright © 2023 The Japanese Respiratory Society.

Background: Medical thoracoscopy (MT) is recommended in patients with undiagnosed exudative pleural effusion and offers a degree of diagnostic sensitivity for pleural malignancy. However, not all patients who undergo MT receive an exact diagnosis. Our previous investigation from 2014 summarized the long-term outcomes of these patients with nonspecific pleurisy (NSP); now, we offer updated data with the goal of refining our conclusions., Methods: Between July 2005 and August 2018, MT with pleural biopsies were performed in a total of 1,254 patients with undiagnosed pleural effusions. One hundred fifty-four patients diagnosed with NSP with available follow-up data were included in the present study, and their medical records were reviewed., Results: A total of 154 patients were included in this study with a mean follow-up duration of 61.5 ± 43.7 months (range: 1-180 months). No specific diagnosis was established in 67 (43.5%) of the patients. Nineteen patients (12.3%) were subsequently diagnosed with pleural malignancies. Sixty-eight patients (44.2%) were diagnosed with benign diseases. Findings of pleural nodules or plaques during MT and the recurrence of pleural effusion were associated with malignant disease., Conclusions: Although most NSP patients received a diagnosis of a benign disease, malignant disease was still a possibility, especially in those patients with nodules or plaques as noted on the MT and a recurrence of pleural effusion. One year of clinical follow-up for NSP patients is likely sufficient. These updated results further confirm our previous study's conclusions., (© 2021. The Author(s).)

A 46-year-old Japanese man was admitted to our hospital with a 1-year history of dyspnea and persistent right-dominant bilateral pleural effusions. Chest and abdominal computed tomography (CT) revealed no notable findings apart from the bilateral pleural effusions. 2-deoxy-2-[ 18 F]-fluoro-D-glucose (FDG) positron emission tomography-CT showed no accumulation of FDG in the thorax and abdomen. Thoracoscopy revealed numerous small (approximately 2-3 mm in size), blister-like nodules on the left parietal pleura extending from the lower third of the chest wall to the diaphragm. A pathological examination revealed lymphocyte and plasma cell infiltrates with increasing numbers of IgG4-positive plasma cells in the fibrotic pleura, indicating IgG4-related pleuritis.

The parietal pleura is often biopsied in patients with idiopathic pleural effusion, and in up to 40% of cases, a diagnosis of nonspecific pleuritis/fibrosis (NSP) is rendered. The histology of this reaction has not been well described including a pattern of B cell lymphoid hyperplasia described as "chronic follicular pleuritis (CFP)". Thirty-two cases of NSP were studied, of which 13 (41%) corresponded to CFP with the remainder displaying a fibrinous and organizing pleuritis with varying degrees of collagenization. CFP had similar etiologies as NSP with long term follow-up, including cardiac disease, pericarditis, asbestos exposure, and occult malignancy. The importance of recognizing a previously undescribed B cell/plasma cell pleural inflammatory response in reactive pleural disease is discussed., (Copyright © 2019 Elsevier Inc.

Background and Objective: Malignant pleurisy is associated with advanced oncological disease and dyspnoea is the most common presenting symptom. Pleurodesis is the preferred palliative and supportive treatment option, targeting symptom relief. The identification of clinical and endoscopic features that determine the success of talc pleurodesis in malignant pleurisy could guide clinical decision-making., Methods: All symptomatic patients with malignant pleurisy subjected to talc pleurodesis through medical thoracoscopy between January 2012 and December 2015 were included. Univariate and multivariate analyses were performed to identify factors associated with successful pleurodesis., Results: Of the 155 patients, 122 (78%) were classified as having a successful pleurodesis based on clinical and radiological criteria. Factors associated with unsuccessful pleurodesis (univariate analysis) were the presence of pleural adhesions (odds ratio (OR): 0.43 (95% CI: 0.19-0.96); P = 0.04), extensive spread of pleural lesions (OR: 0.17 (95% CI: 0.05-0.59); P = 0.001), the use of systemic corticosteroids (OR: 0.28 (95% CI: 0.10-0.83); P = 0.02) and a prolonged time period between the clinical diagnosis of the pleural effusion and the moment of pleurodesis (OR: 0.14 (95% CI: 0.06-0.32); P < 0.0001). The latter being associated with failure of pleurodesis in a multivariate analysis (OR: 0.08 (95% CI: 0.01-0.25); P < 0.0001). Chest ultrasound prior to pleurodesis showed a sensitivity of 91% and a specificity of 88% in predicting the success of pleurodesis., Conclusion: The success rate of pleurodesis in malignant pleurisy could potentially be enhanced by correct patient selection and early referral for pleurodesis. Ultrasonic assessment of pleural adhesions and potential lung expansion prior to pleurodesis is useful in clinical decision-making., (© 2018 Asian Pacific Society of Respirology.)

Background: While nontuberculous mycobacterial (NTM) pleuritis rarely complicates pulmonary NTM infection, high mortality has been reported in case reports and small studies., Objectives: The purpose of this study was to clarify the clinical features and treatment outcomes of pulmonary NTM infection cases accompanied by NTM pleuritis., Methods: Medical records of 1,044 patients with pulmonary NTM disease were retrospectively reviewed to select patients complicated by NTM-proven pleuritis. We investigated clinical characteristics, pathogens, pleural effusion examinations, radiographic findings, treatments, and clinical course of the NTM pleuritis patients., Results: Among 1,044 cases with pulmonary NTM, NTM pleuritis occurred in 15 cases (1.4%). The mean age was 69 years with a performance status of mostly 2 or better (80.0%), and 6 cases (40.0%) were complicated by pneumothorax. Subpleural cavities were radiologically detected in 11 cases (73.3%), and extrapulmonary air-fluid level was detected in 14 cases (93.3%). Eleven patients were treated with combinations of 2-4 antimycobacterial drugs, including clarithromycin, and 2 patients were treated with isoniazid, rifampicin, and ethambutol. Chest tube drainage was performed in 11 cases, and surgical approach was added in 6 cases. The pleural effusion of 2 patients treated with only antimycobacterial medications gradually deteriorated. Two patients died from NTM pleuritis, and 1 patient died from pneumonitis during a mean of 1.8 years of follow-up., Conclusions: Comorbid NTM pleuritis was difficult to treat by medical therapy alone and resulted in a poor prognosis. In addition to antimycobacterial agents, chest tube drainage and surgical procedures in the early stages should be considered to treat NTM pleuritis., (© 2018 The Author(s) Published by S.

Objective To measure the rate of the A2063G mutation in the Mycoplasma pneumoniae ( M. pneumoniae) 23S rRNA domain V in children with pneumonia and to determine the correlation between radiographic findings and the presence of the A2063G mutation. Methods Patients who were hospitalized with a confirmed diagnosis of M. pneumoniae pneumonia were enrolled in this study. M. pneumoniae strains were collected for genotype analysis. Chest radiography was performed on all children prior to and following macrolide treatment. Clinical and imaging data were obtained. Results Of 211 patients, 195 (92.42%) harboured M. pneumoniae with the A2063G mutation. No significant differences were identified in inflammation score, chest radiography inflammation absorption grade before and after macrolide treatment, or pulmonary complications (atelectasis, hydrothorax, or pleuritis) prior to macrolide treatment when children were stratified based on the presence or absence of the A2063G mutation. Conclusions A high proportion of children with pneumonia harboured strains of M. pneumoniae with the A2063G mutation in the 23S rRNA domain V. However, no obvious chest radiographic features of M. pneumoniae pneumonia were associated with the A2063G variant.

Background: Chest ultrasound (CUS) is the gold standard to detect pleural adhesions before pleural maneuvers. However, the CUS technique is not available in all countries where the assessment is only based on clinical examination and chest radiography., Objective: To assess the value of lateral decubitus chest radiography (LDCR) to detect pleural adhesions., Methods: Consecutive patients with pleural effusions undergoing LCDR followed by medical thoracoscopy the day after were identified from an institutional database. The diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for LDCR were calculated., Results: Eighty-six patients were included in the study. The sensitivity, specificity, PPV, and NPV of LDCR for the presence of adhesions taking into account the shape of the horizontal level were 71.2% (56.7-82.5), 44.1% (27.6-61.9), 66.1% (52.1-77.8), and 50% (31.7-68.3), respectively. The accuracy to predict pleural adhesions for the sign "incomplete horizontal level" was 60.5 (49.3-70.7). The accuracy to predict pleural adhesions in case of irregular aspect of the horizontal level was 53.5 (42.5-64.2)., Conclusions: The accuracy of LDCR for the detection of pleural adhesions is low in patients with pleural effusion and LDCR is not sufficient before pleural maneuvers. This has to be taken into account in countries with a high prevalence of pleural tuberculosis which usually lead to loculated pleural effusions. CUS has to be urgently included in dedicated educational programs in these areas in order to decrease the complications related to unexpected pleural adhesions and achieve better planning for the management of pleural effusions., (© 2018 S.

We herein describe the first known case of pleuritis caused by Mycobacterium kyorinense without pulmonary involvement. A 48-year-old man undergoing immunosuppressant therapy presented with cough and dyspnea. An accumulation of pleural fluid was noted; however, computed tomography revealed no pulmonary lesions. Cultures of the fluid yielded non-tuberculous mycobacteria, which was identified as Mycobacterium kyorinense. The patient recovered after 6 months of therapy with clarithromycin and moxifloxacin. Clinicians should be aware that Mycobacterium kyorinense can cause pleuritis without pulmonary involvement. When mycobacterial species are isolated from the pleural fluid, precise identification and drug susceptibility testing are warranted.

Despite similar mechanisms driving pleural fluid accumulation, the causes of pleural effusions in children differ significantly from that of adults. When a pleural effusion re-occurs in an adult, literature recommends early thoracentesis, and consideration for pleuroscopy with biopsy to guide the diagnostic evaluation. In children, there is a paucity of literature for guiding management of recurrent exudative pleural effusion. We present an unusual pediatric case of uremic pleuritis with recurrent pericardial and exudative pleural effusions., (© 2017 Wiley Periodicals, Inc.)

Computed tomography (CT) is the primary imaging modality used to investigate human patients with suspected malignant or inflammatory pleural effusion, but there is a lack of information about the clinical use of this test in dogs. To identify CT signs that could be used to distinguish pleural malignant neoplasia from pleuritis, a retrospective case-control study was done based on dogs that had pleural effusion, pre- and postcontrast thoracic CT images, and cytological or histopathological diagnosis of malignant or inflammatory pleural effusion. There were 20 dogs with malignant pleural effusion (13 mesothelioma, 6 carcinoma; 1 lymphoma), and 32 dogs with pleuritis (18 pyothorax; 14 chylothorax). Compared to dogs with pleuritis, dogs with malignant pleural effusions were significantly older (median 8.5 years vs. 4.9 years, P = 0.001), more frequently had CT signs of pleural thickening (75% vs.44%, P = 0.04), tended to have thickening of the parietal pleura only (65% vs. 13%, P = 0.01) and had more marked pleural thickening (median 3 mm vs. 0 mm, P = 0.01). Computed tomography signs of thoracic wall invasion were observed only in dogs with malignant pleural effusions (P = 0.05). There were no significant differences in pleural fluid volume, distribution or attenuation, degree of pleural contrast accumulation, amount of pannus, or prevalence of mediastinal adenopathy. Although there was considerable overlap in findings in dogs with malignant pleural effusion and pleuritis, marked thickening affecting the parietal pleural alone and signs of thoracic wall invasion on CT support diagnosis of pleural malignant neoplasia, and may help prioritize further diagnostic testing., (© 2017 American College of Veterinary Radiology.)

Background: Medical thoracoscopy is an effective and safe procedure for diagnosing pleural effusions of undetermined causes. But there are still a part of patients with pleural effusions were diagnosed as nonspecific pleurisy when no specific biopsy results were found after undergoing thoracoscopic biopsy. The long-term outcome of these patients is unclear, and anxieties about undiagnosed malignancy persist., Methods: Between July 2005 and June 2014, medical thoracoscopy using the semi-rigid instrument was performed and pleural biopsy was taken in 833 patients with pleural effusions. Fifty-two patients diagnosed with nonspecific pleurisy with available follow-up data were included in the present study and their medical records were reviewed., Results: Fifty-two patients (31 men and 21 women) were included. Mean follow up was 35.5 ± 40.9 months (range, 1-143 months). No specific diagnosis was established in 21 (40.4%) of the patients. Eight of 52 patients with nonspecific pleurisy (15.4%) were subsequently diagnosed with pleural malignancies. 23 of 52 patients (44.2%) were diagnosed as benign diseases. The recurrence of pleural effusion during followed-up and pleural nodules or plaques found in medical thoracoscopy was associated with malignant disease., Conclusion: Patients with nonspecific pleurisy after medical thoracoscopy should be closely monitored, especially in those patients with the recurrence of pleural effusion during followed-up, pleural nodules or plaques found in medical thoracoscopy. One year of clinical follow-up for patients found to have nonspecific pleurisy is likely sufficient., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Although everolimus, a mammalian target of rapamycin inhibitor, has been used as a potent immunosuppressive agent in organ transplantation, data regarding its adverse effect profile compared with that of sirolimus in clinical circumstances are limited. A 50-year-old man who underwent simultaneous liver and kidney transplantation 14 months previously was admitted with large pleural effusion, pericardial effusion, and ascites. Laboratory findings and cultures for possible infectious causes were all negative. Pericardial window surgery with drainage of the pericardial fluid was performed on day 3. Pleural and pericardial biopsy revealed non-specific inflammation without evidence of malignant cells. Everolimus was discontinued and replaced by mycophenolate mofetil on day 4. Significant clinical improvement was observed after discontinuation of everolimus, and follow-up echocardiography and chest radiography showed no recurrence of the pericardial or pleural effusion after discharge., (Copyright © 2016 Elsevier Inc.

Introduction: Whereas numerous case reports have described statin-induced lung injuries, statin-induced pleural effusions are uncommon., Case Report: An 84-year-old man presented with bilateral pleural effusions two years after starting treatment with atorvastatin. No other cause of pleural effusion was found and all symptoms and radiological signs resolved rapidly after discontinuation of the drug. Furthermore, an accidental reintroduction of the treatment resulted in recurrence of the same clinical picture, reinforcing the hypothesis that atorvastatin was responsible for this pleural effusion., Conclusion: Pleuropulmonary manifestations in a patient treated with atorvastatin should rapidly evoke an iatrogenic origin and the discontinuation of the drug should be discussed., (Copyright © 2016 SPLF.

Adult onset Still's disease (AOSD) is an uncommon, multisystemic, auto-inflammatory disorder, while breast augmentation is a very common cosmetic procedure. We describe a case in which these two coalesce, AOSD, manifested with pleuritis and pericarditis, developed after breast mammoplasty. The pathogenetic, missing link, behind the development of AOSD following mammoplasty, is thought to be the autoimmune (auto-inflammatory) syndrome induced by adjuvants (ASIA). We reviewed other cases of AOSD associated with breast mammoplasty published to date and the literature regarding AOSD and ASIA syndrome. The review is followed by a short debate of whether silicone implants should be explanted in similar, future cases.

Differentiated tactics of diagnostic videothoracoscopy (VTHS) in a pleural exudate syndrome, which ought to be treated with hydrothorax elimination and artificial pneumothorax creation, was proposed. Further roentgenological investigation permits to create a plan for the operation conduction and a certain anesthesia application. Criteria for the operation planning and the anesthesiological support choice were elaborated. Results of VTHS conduction in 261 patients in Department of Thoracic Surgery were analyzed. The differentiated tactics for the VTHS performance application have had saved the patients from the unnecessary endotracheal narcosis conduction, and reduced a pharmacological load on a patient, as well as a rate of contraindications for the operation usage and the stationary treatment duration.

Pleural infection is increasing in incidence. Despite optimal medical management, up to 30% of patients will die or require surgery. Case reports suggest that irrigation of the pleural space with saline may be beneficial.A randomised controlled pilot study in which saline pleural irrigation (three times per day for 3 days) plus best-practice management was compared with best-practice management alone was performed in patients with pleural infection requiring chest-tube drainage. The primary outcome was percentage change in computed tomography pleural fluid volume from day 0 to day 3. Secondary outcomes included surgical referral rate, hospital stay and adverse events.35 patients were randomised. Patients receiving saline irrigation had a significantly greater reduction in pleural collection volume on computed tomography compared to those receiving standard care (median (interquartile range) 32.3% (19.6-43.7%) reduction versus 15.3% (-5.5-28%) reduction) (p<0.04). Significantly fewer patients in the irrigation group were referred for surgery (OR 7.1, 95% CI 1.23-41.0; p=0.03). There was no difference in length of hospital stay, fall in C-reactive protein, white cell count or procalcitonin or adverse events between the treatment groups, and no serious complications were documented.Saline irrigation improves pleural fluid drainage and reduces referrals for surgery in pleural infection. A large multicentre randomised controlled trial is now warranted to evaluate its effects further., (Copyright ©ERS 2015.)

Familial Mediterranean fever (FMF) is a hereditary autosomal recessive ,systemic, auto-inflammatory disorder characterized by sporadic, unpredictable attacks of fever and serosal inflammation. FMF is caused by mutations in MEFV, a gene located on the short arm of chromosome 16 (16p13) which encodes a protein 'Pyrin'. The disorder has been given various names including familial paroxysmal polyserositis, periodic peritonitis, recurrent polyserositis, benign paroxysmal peritonitis, and periodic disease or periodic fever, As the name indicates, FMF occurs within families and is much more common in individuals of Mediterranean descent than in persons of any other ethnicity. It has been described in several ethnic groups including Sephardic Jews, Armenians, Turks, North Africans, Arabs, Greeks, and Italians. However, the disease is not restricted to these groups and sporadic cases have been reported. Diagnosis is usually clinical and it classically presents with unprovoked, recurrent attacks of fever and painful polyserositis mainly affecting the peritoneum (most common), synovium, and pleura that usually (but not always) begin in childhood. We present a atypical case of FMF with type 1 Diabetes Mellitus and FMF who had no fever, Mediterranean ancestory or family history and discuss his clinical features,diagnosis and management., (© Journal of the Association of Physicians of India 2011.)

The definitive diagnosis of pleural malignancy depends upon histological confirmation by pleural biopsy. CT is reported to have a high sensitivity and specificity for the diagnosis of malignant pleural disease, and is part of the routine diagnostic workup of these patients. The aim of this study was to assess the sensitivity and specificity of CT in detecting pleural malignancy prior to definitive histology obtained via thoracoscopy in a large cohort of patients with suspected malignant pleural disease. Retrospective review of thoracoscopies between January 2008 and January 2013 at two UK tertiary referral centres: Oxford and Preston. The histological results were compared with the CT reported diagnosis before the procedure. CT scan reports were assessed by independent respiratory physicians as to whether the radiologist concluded evidence of malignant pleural disease or benign features only. 211 (57%) of 370 patients included in the analysis had malignant disease: CT scans were reported as 'malignant' in 144, giving a sensitivity of 68% (95% CI 62% to 75%). Of the 159 patients with benign disease, 124 had CT scans reported as benign: specificity 78% (72% to 84%). The positive predictive value of a malignant CT report was 80% (75% to 86%), with a negative predictive value of 65% (58% to 72%). A significant proportion of patients being investigated for malignant disease will have malignancy despite a negative CT report. The use of CT alone in determining which patients should have invasive pleural biopsies should be re-evaluated, and further studies to define the diagnostic pathway are now required., (Published by the BMJ Publishing Group Limited.

Systemic lupus erythematosis (SLE) can affect the lungs and pleura, usually manifesting with pleural effusions or diffuse parenchymal disease. A rare manifestation of SLE is shrinking lung syndrome, a severe restrictive respiratory disorder. While pleuropulmonary complications of pediatric SLE are common, shrinking lung syndrome is exceedingly rare in children. We present a case of a 13-year-old girl previously diagnosed with lupus, who developed severe dyspnea on exertion and restrictive pulmonary physiology. Her chest radiographs on presentation demonstrated low lung volumes, and CT showed neither pleural nor parenchymal disease. Fluoroscopy demonstrated poor diaphragmatic excursion. While shrinking lung syndrome is described and studied in adults, there is only sparse reference to shrinking lung syndrome in children.

A 24-year-old man presented with fever and pleural effusion predominantly containing lymphocytes. Cultures of the pleural effusion and blood revealed Campylobacter fetus, and laboratory studies showed a low serum level of immunoglobulin. The patient was diagnosed with C. fetus pleuritis, bacteremia and primary hypogammaglobulinemia, and subsequent treatment with meropenem and immunoglobulin improved his condition. Although the underlying cause of the primary hypogammaglobulinemia remains unclear, the patient's status improved under immunoglobulin replacement therapy. C. fetus pleuritis is a rare infectious disease usually observed in immunocompromised hosts. We herein describe the first report of C. fetus pleuritis in a young adult with primary hypogammaglobulinemia.

Following three brief clinical reports, we review the literature concerning a rare cause of exudative pleural effusion: the presence of a foreign body in the pleural cavity. Frequently iatrogenical, this rare etiology of pleural effusion must be envisaged when this complication develops after any invasive peri-thoracic surgery and must be included in the differential diagnosis of recurrent pleural effusions. These effusions have a favorable prognosis after withdrawal of the foreign body.

Chickenpox is a viral infection usually benign and practically mandatory of the childhood. In the adult, it may know multivisceral complications as pneumonia in relationship with chickenpox which is the most frequent. One case of varicella pneumonia with a bilateral pleurisy has been noticed in a 38-year-old adult. The definite diagnosis has been based on clinical, biological and radiological arguments. Under an antiviral treatment, the evolution is favourable., (Copyright © 2013. Published by Elsevier Masson SAS.)

Objective: The pathophysiology of shrinking lung syndrome (SLS) is poorly understood. We sought to define the structural basis for this condition through the study of pulmonary mechanics in affected patients., Methods: Since 2007, most patients evaluated for SLS at our institutions have undergone standardized respiratory testing including esophageal manometry. We analyzed these studies to define the physiological abnormalities driving respiratory restriction. Chest computed tomography data were post-processed to quantify lung volume and parenchymal density., Results: Six cases met criteria for SLS. All presented with dyspnea as well as pleurisy and/or transient pleural effusions. Chest imaging results were free of parenchymal disease and corrected diffusing capacities were normal. Total lung capacities were 39%-50% of predicted. Maximal inspiratory pressures were impaired at high lung volumes, but not low lung volumes, in 5 patients. Lung compliance was strikingly reduced in all patients, accompanied by increased parenchymal density., Conclusion: Patients with SLS exhibited symptomatic and/or radiographic pleuritis associated with 2 characteristic physiological abnormalities: (1) impaired respiratory force at high but not low lung volumes; and (2) markedly decreased pulmonary compliance in the absence of identifiable interstitial lung disease. These findings suggest a model in which pleural inflammation chronically impairs deep inspiration, for example through neural reflexes, leading to parenchymal reorganization that impairs lung compliance, a known complication of persistently low lung volumes. Together these processes could account for the association of SLS with pleuritis as well as the gradual symptomatic and functional progression that is a hallmark of this syndrome.

Though pleuritis and pleural effusion are common in lupus patients they are distinctly rare as the initial manifestation of lupus. Diagnosis of lupus pleuritis is also a difficult task and often costly and lengthy immunological panels are employed to diagnose it. We report one case of systemic lupus erythematosus (SLE) presenting with lupus pleuritis as the first manifestation. We propose that demonstration LE cells have a very prominent role in differentiating lupus pleuritis from other causes of pleural effusions in SLE patients. We believe that our case is the first report from India which shows pleuritis may be a first manifestation of lupus.

Which course of action should be taken during the incidental finding of pleural thickening on chest X-ray? Aftereffect, without consequence, of an injury of the pleura, or potentially serious subclinical pathology? The differential diagnosis is wide, the radiograph nonspecific and the interobserver variability significant. In the absence of epidemiological studies and guidelines, the history and clinical examination remain the main factors in dictating investigations and management. Apical pleural thickening, which is nonspecific in the absence of parenchymal lesions, does not influence treatment recommendations for tuberculosis. Pleural plaques do not appear to increase the risk of cancer associated with asbestos and, thus, do not modify post-exposure follow-up. Incidental finding of pleural thickening remains a gray zone that opens the door to new studies.

Background: There are limited published data defining complete pleural fluid analysis, echocardiographic characteristics, or the presence or absence of ascites on sonographic or CT imaging in patients with hepatic hydrothorax., Methods: We reviewed pleural fluid analysis and radiographic, sonographic, and echocardiographic findings in 41 consecutive patients with hepatic hydrothorax referred to the Pleural Procedure Service for thoracentesis., Results: Ascites was detected on sonographic or CT imaging in 38 of 39 patients (97%). Diastolic dysfunction was found in 11 of 21 patients (52%). Contrast echocardiography with agitated saline demonstrated an intrapulmonary shunt in 18 of 23 cases (78%). Solitary hepatic hydrothorax had a median pleural fluid pH of 7.49 (fifth to 95th percentile, 7.40-7.57), total protein level of 1.5 g/dL (0.58-2.34), and lactate dehydrogenase (LDH) level of 65 IU/L (36-138). The median pleural fluid/serum protein ratio and pleural LDH/upper limit of normal serum LDH ratio were 0.25 (0.10-0.43) and 0.27 (0.14-0.57), respectively. The median absolute neutrophil count (ANC) was 26 cells/μL (1-230). Only a single patient had a protein discordant exudate despite 83% of patients receiving diuretics. When comparing solitary hepatic hydrothorax and spontaneous bacterial pleuritis, there was no statistically significant difference among pleural fluid total protein (P = .99), LDH (P = .33), and serum albumin (P = .47). ANC was higher in patients with spontaneous bacterial pleuritis (P < .0001)., Conclusions: Hepatic hydrothorax virtually always presents with ascites that is detectable on sonographic or CT imaging. The development of an "exudate" from diuretic therapy is a rare phenomenon in hepatic hydrothorax. In contrast, diastolic dysfunction and intrapulmonary shunting are common in patients with hepatic hydrothorax. There was no statistically significant change in pleural fluid parameters with spontaneous bacterial pleuritis, except an increased ANC.

Empyema after lung resection is a challenging condition to manage and is associated with a high mortality. Intrathoracic application of a vacuum-assisted closure (VAC) device is recently introduced as an adjunct in the management of this condition. A best evidence topic was constructed to address whether this approach is effective in successful chest closure and reducing hospital stay. Twenty-three papers were found using the reported search, of which nine papers were identified that provided the best evidence to answer the question. All papers were retrospective and included a total of 69 patients treated with intrathoracic VAC. There was only one cohort study and the rest were either case series or case reports. In a cohort of 19 patients reported by Palmen et al. the average duration of an open window thoracostomy in a group of patients with VAC (n=11) was 39 ± 17 days and in those without VAC (n=8) was 933 ± 1422 days. Median length of VAC treatment was 22 days (range 6-66 days) in a series of 28 patients reported by Saadi et al. Some authors excluded patients with a bronchopleural fistula (BPF) from VAC treatment. However, Groetzner et al. have safely used VAC in patients with BPF after covering the bronchus stump with an intrathoracic muscle flap. The mediastinum and the bronchus can be covered using a polyvinyl-alcohol foam. Polyurethane foam is commonly used to fill the intrathoracic cavity up to the superficial wound. The suggested starting level of negative pressure is as low as -25 mmHg to -75 mmHg depending on the presence or absence of signs of mediastinal traction; this negative pressure can gradually be increased to -125 mmHg over time. The recommended interval between VAC changes is two to five days. Accumulated evidence in this article, although limited, suggests that VAC, as an adjunct to the standard treatment, can potentially alleviate the morbidity and decrease hospital stay in patients with empyema after lung resection. VAC can reduce inpatient length of treatment and can make the condition manageable in an outpatient setting. These results are yet to be proven by larger studies and clinical trials.

Introduction: The authors report their experience in the use of subcutaneous implantable pleural port (SIPP) catheters for the treatment of symptomatic recurrent malignant pleurisy., Materials and Methods: Single-center, prospective follow-up of 137 patients (168 SIPPs)., Results: No SIPP placement failures were observed. All but 3 of the 125 evaluable patients obtained complete or partial relief of their dyspnea. Seventy-six patients (60.3%) were receiving chemotherapy. Spontaneous pleurodesis was observed within 2 months in 46 patients (36.8%). Twenty-six patients (20.8%) died during the month following SIPP placement. Forty-one patients (32%) survived for more than 6 months. The overall median survival time was 344 days. Three infectious complications (1 empyema, 2 cellulitis) and 3 mechanical complications were observed. The role of pleurodesis as prognostic factor was assessed. Seventy-one patients survived for more than 2 months, 36 with pleurodesis, 35 without pleurodesis, requiring repeated pleural aspiration. The difference observed between the two groups by the 120th day was no longer significant when chemotherapy was taken into account., Conclusion: SIPP is a safe and effective option for the outpatient management of recurrent malignant effusions and could be considered as first-line treatment in all patients with bilateral, compressive pleural effusion or poor lung reexpansion.

The purpose of the present study was to evaluate cattle and buffaloes with respiratory disorders, determine the extent of the lesions, and assess prognosis. The results were compared with the findings determined following physical examination and at slaughter. Animals were referred to Veterinary Teaching Hospitals because of inappetance, loss of body condition, cough, dyspnea, and nasal discharges. Ultrasonographically, it was possible to detect bronchopneumonia, consolidation, pleural effusion, pulmonary emphysema, and pleuritis. It was not possible to visualize lesions located deeper within the lungs where peripheral tissue was not affected. Laboratory findings included a neutrophilic leukocytosis, γ-globulinemia, and increased activity of aspartate aminotransferase. A diagnosis of respiratory disease was made on the basis of clinical and ultrasonographic findings and confirmed in 25 cases at slaughter. Bovine ultrasonography appears to be suitable as a screening tool for detection of pathologic lung processes near the pleura. Thoracic ultrasonography allows assessment of the extent and severity of pulmonary changes so that further evaluations can be considered.

The study was undertaken to improve ultrasonography using needle biopsy under ultrasound control in the diagnosis of pleurisies of various etiologies. The patients of the Department of Thoracic Surgery, who had been divided by the nosological principle (nonspecific pleurisy, tuberculosis effusions, and tumorous and posttraumatic pleurisies), were followed up. The study and statistical processing yielded major ultrasound criteria for pleural effusions and a final diagnosis was made on the basis of needle biopsy under ultrasound control with subsequent morphological verification.

Unlabelled: Pleural effusions are still representing a challenge in daily practice., Materials and Methods: This retrospective study on 221 patients with pleurisies hospitalized in our unit is focused on the contribution of different types of pleural fluid morphological evaluation in setting a correct etiological diagnosis. The algorithm of investigation included: gross aspects assessment on X-ray records and by direct observation of pleural liquid obtained by thoracentesis and microscopic assessment on cytology slides of pleural fluid and on histopathological samples obtained by pleural needle biopsies., Results: Mycobacterial etiology was the most frequent, with 72% of all cases, followed by tumoral etiology. Cytologic examination of pleural fluid was useful in establishing the final diagnosis in 66.1% of cases, histopathological assessment being imposed for the rest of cases., Discussion: Imagistic investigation offered appropriate information concerning the site and extention of pleural effusions and guided, in certain cases, the needle biopsy. Gross aspect of pleural fluid oriented quite well the suspicion diagnosis. The use of a set of cytological "formulas" was useful in filtering subsequently the suspicion diagnosis. Histopatholgical examination of pleural tissue samples established the final diagnosis in cases where etiology was still uncertain after laboratory and cytological examination and subtyped further the pathologic processes within each main category of etiology., Conclusions: A correct diagnosis of pleural effusions could be achieved only by going through a precise algorithm of investigation where, besides thorough clinical examination and laboratory tests especially of pleural liquid, morphological assessment and in particular cytologic examination of pleural liquid and histopatological examination of pleural tissue samples are essential.

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., (Copyright © 2010 Formosan Medical Association & Elsevier.

Epidemic pleurodynia is seldom reported in Southeast Asia and there has been no report from Taiwan. We conducted a retrospective chart review of children = 18 years of age in the National Taiwan University Hospital from January 1 to December 31, 2005. Epidemic pleurodynia was defined as an acute illness characterized by sharp localized pain over the chest or upper abdomen. Patients with known heart diseases or pulmonary consolidations were excluded. In total, 28 patients met the case definition of epidemic pleurodynia. Coxsackievirus B3 (CB3) was isolated in 15 (60%) of the 25 throat swab specimens. Four (14%) of the 28 patients presented chest wall tenderness and only one (6%) of the 18 patients tested had an elevated creatinine kinase level. Twenty-one (75%) of the 28 patients described pleuritic chest pains and 10 (45%) of the 22 chest radiographies exhibited pulmonary infiltrates or pleural effusions. Six patients were observed with tonsillar exudates and one was confirmed to have a CB3 urinary tract infection. The clinical features and radiological findings suggest that CB3-associated epidemic pleurodynia might be a disease of the pleura and occasionally spreads to nearby tissues, resulting in chest wall myositis, pulmonary infiltrates and myopericarditis., (Copyright © 2010 Taiwan Society of Microbiology.

Introduction: Positron emission tomography (PET) now plays a clear role in oncology, especially in chest tumours. We discuss the value of metabolic imaging in characterising pleural pathology in the light of our own experience and review the literature., Background: PET is particularly useful in characterising malignant pleural pathologies and is a factor of prognosis in mesothelioma. Metabolic imaging also provides clinical information for staging lung cancer, in researching the primary tumour in metastatic pleurisy and in monitoring chronic or recurrent pleural pathologies., Conclusions: PET should therefore be considered as a useful tool in the diagnosis of liquid or solid pleural pathologies., (Copyright © 2010 SPLF.
