RESUMEN
BACKGROUND: Chest drain displacement is a common clinical problem that occurs in 9-42% of cases and results in treatment failure or additional pleural procedures conferring unnecessary risk. A novel chest drain with an integrated intrapleural balloon may reduce the risk of displacement. METHODS: A prospective randomised controlled trial comparing the balloon drain to standard care (12â F chest drain with no balloon) with the primary outcome of objectively defined unintentional or accidental chest drain displacement. RESULTS: 267 patients were randomised (primary outcome data available in 257, 96.2%). Displacement occurred less frequently using the balloon drain (displacement 5 of 128, 3.9%; standard care displacement 13 of 129, 10.1%) but this was not statistically significant (OR for drain displacement 0.36, 95% CI 0.13-1.0, Chi-squared 1â degree of freedom (df)=2.87, p=0.09). Adjusted analysis to account for minimisation factors and use of drain sutures demonstrated balloon drains were independently associated with reduced drain fall-out rate (adjusted OR 0.27, 95% CI 0.08-0.87, p=0.028). Adverse events were higher in the balloon arm than the standard care arm (balloon drain 59 of 131, 45.0%; standard care 18 of 132, 13.6%; Chi-squared 1â df=31.3, p<0.0001). CONCLUSION: Balloon drains reduce displacement compared with standard drains independent of the use of sutures but are associated with increased adverse events specifically during drain removal. The potential benefits of the novel drain should be weighed against the risks, but may be considered in practices where sutures are not routinely used.

BACKGROUND: Solitary fibrous tumours of the pleura (SFTP), or pleural fibromas, are rare tumours that generally, but not universally, follow a benign course. Surgical resection is the standard treatment, but there are no evidence-based guidelines regarding the management of these tumours. METHODS: Five databases were searched from inception to April 1, 2019 for studies reporting on SFTP management. RESULTS: Twenty-seven studies met the inclusion criteria (1542 patients, all non-comparative case series); 98% of these patients underwent resection and all SFTP included were pathologically diagnosed. 394 out of 1299 cases (30.5%, 95% CI 27.8-32.8%) were malignant with recurrence rates of between 0% and 42.9%. A pleural effusion was always associated with a negative outcome, but no other features were consistently reported to have negative associations. Preoperative biopsies incorrectly reported malignant histology in two studies. Over 25% of cases of recurrence occurred when a complete (R0) resection had been achieved. The first recurrence occurred >5â years after the initial resection in at least 23% of cases. CONCLUSIONS: There is strong evidence to support long-term surveillance after surgical resection of SFTP, even where a complete (R0) resection has been achieved; however, there is no clear evidence to inform clinicians regarding the selection of patients who should undergo resection. The rates of malignant SFTP and SFTP recurrence are higher than previously reported. Only those that were pathologically diagnosed or resected were included, which may bias the data towards more aggressive tumours. Data collection on radiologically diagnosed SFTP is required to draw conclusions regarding the timing and need for intervention.
RESUMEN
BACKGROUND AND OBJECTIVE: Chemical pleurodesis is performed for patients with MPE with a published success rate of around 80%. It has been postulated that inflammation is key in achieving successful pleural symphysis, as evidenced by higher amounts of pain or detected inflammatory response. Patients with mesothelioma are postulated to have a lower rate of successful pleurodesis due to lack of normal pleural tissue enabling an inflammatory response. METHODS: The TIME1 trial data set, in which pleurodesis success and pain were co-primary outcome measures, was used to address a number of these assumptions. Pain score, systemic inflammatory parameters as a marker of pleural inflammation and cancer type were analysed in relation to pleurodesis success. RESULTS: In total, 285 patients were included with an overall success rate of 81.4%. There was a significantly higher rise in CRP in the Pleurodesis Success group compared with the Pleurodesis Failure group (mean difference: 19.2, 95% CI of the difference: 6.2-32.0, P = 0.004) but no significant change in WCC. There was no significant difference in pain scores or analgesia requirements between the groups. Patients with mesothelioma had a lower rate of pleurodesis success than non-mesothelioma patients (73.3% vs 84.9%, χ2 = 5.1, P = 0.023). CONCLUSION: Change in CRP during pleurodesis is associated with successful pleurodesis but higher levels of pain are not associated. Patients with mesothelioma appear less likely to undergo successful pleurodesis than patients with other malignancies, but there is still a significant rise in systemic inflammatory markers. The mechanisms of these findings are unclear but warrant further investigation.

BACKGROUND: Pleural effusion echogenicity on ultrasound has previously been suggested to allow identification of exudates. A case series suggested that homogenously echogenic effusions are always exudates. With modern imaging techniques and more advanced ultrasound technology, this may no longer be true. OBJECTIVES: This study aims to prospectively assess the predictive value of echogenicity in the identification of exudates. METHOD: Patients undergoing thoracic ultrasound before pleural fluid sampling were analysed prospectively (n = 140). Pleural fluid was classified as an exudate if both fluid total protein (TP) > 29 g/L and fluid lactate dehydrogenase (LDH) > 2/3 upper limit of normal serum LDH (which is 255 IU/L in females and 235 IU/L in males) were present. If only one of these criteria was met, the effusion was considered to have discordant biochemistry. RESULTS: Fifty-five (39%) patients had non-echogenic and 85 (61%) had echogenic effusions. Six (7.1%) patients with echogenic effusions had transudates; the median fluid TP for this group was 18.5 g/L (IQR 9.75) and median LDH 63.0 IU/L (IQR 40.3). The specificity of echogenicity identifying exudates from transudates, excluding patients with discordant biochemistry, was 57.1%, positive predictive value (PPV) 90.3%, sensitivity 65.1%, and negative predictive value (NPV) 21.0%. The specificity of echogenicity identifying exudates (including discordant biochemistry) from transudates was 57.1%, PPV 92.9%, sensitivity 62.7%, and NPV 14.5%. CONCLUSIONS: Echogenicity of a pleural effusion has a low specificity for identifying an underlying exudate, and the echogenic qualities of the fluid should not influence clinical decision-making.

Prior talc pleurodesis does not result in worsened outcomes from subsequent indwelling pleural catheter use, and patients should not be dissuaded from choosing talc as a primary treatment for recurrent pleural effusion. http://ow.ly/qAAC30mYmr3.
RESUMEN
BACKGROUND: Malignant pleural effusion (MPE) is common and imposes a significant burden on patients and health-care providers. Most patients require definitive treatment, usually drainage and chemical pleurodesis, to relieve symptoms and prevent fluid recurrence. Thoracic ultrasound (TUS) can identify the presence of pleural adhesions in other clinical scenarios, and could therefore have a role in predicting long-term pleurodesis success or failure in MPE. METHODS: Patients undergoing chest tube drainage and talc slurry pleurodesis for symptomatic MPE were recruited to a prospective observational cohort pilot study assessing whether TUS findings pre-talc and post-talc instillation predicted treatment outcome. Participants underwent TUS examination immediately before, and 24 h after talc slurry administration to derive pleural adherence scores for the affected hemithorax. The recorded TUS scans were additionally scored by two independent assessors blinded to the patient's clinical status. The primary outcome was pleurodesis success at 1-month and 3-month follow-up. RESULTS: Eighteen participants were recruited to the pilot study. Participants who suffered pleurodesis failure had a lower pleural adherence score at 24 h post-talc instillation than those who were successful (difference of 6.27; 95% CI, 3.94-8.59). TUS examination was acceptable to patients, while TUS scoring was highly consistent across all assessors (intraclass correlation coefficient, 0.762; 95% CI, 0.605-0.872). CONCLUSION: A TUS-derived pleural adherence score may facilitate early prediction of long-term outcomes following chemical pleurodesis, with implications for personalized care and decision making in MPE. Further research is needed to evaluate this novel finding. TRIAL REGISTRY: ClinicalTrials.gov; No. NCT02625675; URL: www.clinicaltrials.gov.

BACKGROUND: The prevalence of malignant pleural effusion is increasing worldwide, but prognostic biomarkers to plan treatment and to understand the underlying mechanisms of disease progression remain unidentified. The PROMISE study was designed with the objectives to discover, validate, and prospectively assess biomarkers of survival and pleurodesis response in malignant pleural effusion and build a score that predicts survival. METHODS: In this multicohort study, we used five separate and independent datasets from randomised controlled trials to investigate potential biomarkers of survival and pleurodesis. Mass spectrometry-based discovery was used to investigate pleural fluid samples for differential protein expression in patients from the discovery group with different survival and pleurodesis outcomes. Clinical, radiological, and biological variables were entered into least absolute shrinkage and selection operator regression to build a model that predicts 3-month mortality. We evaluated the model using internal and external validation. FINDINGS: 17 biomarker candidates of survival and seven of pleurodesis were identified in the discovery dataset. Three independent datasets (n=502) were used for biomarker validation. All pleurodesis biomarkers failed, and gelsolin, macrophage migration inhibitory factor, versican, and tissue inhibitor of metalloproteinases 1 (TIMP1) emerged as accurate predictors of survival. Eight variables (haemoglobin, C-reactive protein, white blood cell count, Eastern Cooperative Oncology Group performance status, cancer type, pleural fluid TIMP1 concentrations, and previous chemotherapy or radiotherapy) were validated and used to develop a survival score. Internal validation with bootstrap resampling and external validation with 162 patients from two independent datasets showed good discrimination (C statistic values of 0·78 [95% CI 0·72-0·83] for internal validation and 0·89 [0·84-0·93] for external validation of the clinical PROMISE score). INTERPRETATION: To our knowledge, the PROMISE score is the first prospectively validated prognostic model for malignant pleural effusion that combines biological and clinical parameters to accurately estimate 3-month mortality. It is a robust, clinically relevant prognostic score that can be applied immediately, provide important information on patient prognosis, and guide the selection of appropriate management strategies.

BACKGROUND: Pleural infection is a common complication of pneumonia associated with high mortality and poor clinical outcome. Treatment of pleural infection relies on the use of broad-spectrum antibiotics because reliable pathogen identification occurs infrequently. We performed a feasibility interventional clinical study assessing the safety and significance of ultrasound (US)-guided pleural biopsy culture to increase microbiological yield. In an exploratory investigation, the 16S ribosomal RNA technique was applied to assess its utility on increasing speed and accuracy vs standard microbiological diagnosis. METHODS: Twenty patients with clinically established pleural infection were recruited. Participants underwent a detailed US scan and US-guided pleural biopsies before chest drain insertion, alongside standard clinical management. Pleural biopsies and routine clinical samples (pleural fluid and blood) were submitted for microbiological analysis. RESULTS: US-guided pleural biopsies were safe with no adverse events. US-guided pleural biopsies increased microbiological yield by 25% in addition to pleural fluid and blood samples. The technique provided a substantially higher microbiological yield compared with pleural fluid and blood culture samples (45% compared with 20% and 10%, respectively). The 16S ribosomal RNA technique was successfully applied to pleural biopsy samples, demonstrating high sensitivity (93%) and specificity (89.5%). CONCLUSIONS: Our findings demonstrate the safety of US-guided pleural biopsies in patients with pleural infection and a substantial increase in microbiological diagnosis, suggesting potential niche of infection in this disease. Quantitative polymerase chain reaction primer assessment of pleural fluid and biopsy appears to have excellent sensitivity and specificity.

IgG4-related disease (IgG4-RD) is a multi-system fibro-inflammatory disorder with classical histopathological findings, often in the context of elevated serum IgG4 levels. The thoracic manifestations of IgG4-RD are numerous and can mimic several common and better known conditions. The objective of this study was to outline the frequency and nature of thoracic involvement in a prospective cohort of IgG4-RD patients who met defined diagnostic criteria. Over 40% of IgG4-RD patients had clinicoradiological and/or histological evidence of thoracic involvement, predominantly mediastinal lymphadenopathy, the majority associated with multi-system disease outside the chest. Thoracic involvement was associated with a higher serum IgG4 level, potentially representing greater disease activity or spread. Our data highlight the diverse nature of thoracic IgG4-RD, and the importance of knowledge and recognition of the condition among respiratory physicians who are likely to encounter this disease entity on an increasing basis.

PURPOSE OF REVIEW: Small-bore chest tubes are widely used in the management of common pleural disease. Guidelines suggest that patients with malignant pleural effusions, pneumothorax and pleural infection may be successfully managed with small-bore drains. However, good quality data is often lacking. This article reviews the evidence for the treatment efficacy and potential adverse effects of different chest tube sizes. RECENT FINDINGS: In a large randomised study, the small difference in pain scores between large and small drains was not clinically significant. However, small-bore chest tubes commonly suffer from blockage or inadvertent removal, and may not be as effective in providing successful pleurodesis for malignant pleural effusions. SUMMARY: Although they may be effective in managing pleural infection, and less painful than large drains, small bore drains may be less effective for pleurodesis.

Mycobacterium bovis is a rare cause of tuberculosis in humans, but should be considered in individuals at risk secondary to medical comorbidities (notably immunocompromise) or occupational exposure. Most cases are secondary to reactivation of latent infection in elderly individuals although cases of primary infection still occur, usually involving animal-to-human transmission. Pleural fluid culture in the context of suspected tuberculous pleuritis is frequently negative and pleural biopsy significantly increases the likelihood of confirming the diagnosis histologically and microbiologically. Although thoracoscopic biopsies are the reference standard, closed pleural biopsies are an appropriate and more accessible alternative in the majority of cases - these should be done under direct ultrasound guidance to maximise diagnostic yield. Treatment for M. bovis infection is with prolonged combination anti-tuberculous therapy, using an alternative to pyrazinamide as the organism is inherently resistant to this drug.

Use of medical thoracoscopy by respiratory physicians is increasing. This survey of experienced thoracoscopists was conducted to establish current practice of medical thoracoscopy and physicians' opinion of theoretical cases using 20 video clips. Results suggest an increasing trend towards day-case thoracoscopy but that caution is required when making diagnosis on macroscopic appearance: malignant and benign disease could only be differentiated in 59% of cases, and trapped lung is difficult to predict at thoracoscopy.

Patients with an unexplained pleural effusion often require urgent investigation. Clinical practice varies due to uncertainty as to whether an effusion should be drained completely before diagnostic imaging. We performed a retrospective study of patients undergoing medical thoracoscopy for an unexplained effusion. In 110 patients with paired (pre- and post-drainage) chest X-rays and 32 patients with paired computed tomography scans, post-drainage imaging did not provide additional information that would have influenced the clinical decision-making process.

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.
RESUMEN
BACKGROUND: The minimal important difference (MID) is essential for interpreting the results of randomised controlled trials (RCTs). Despite a number of RCTs in patients with malignant pleural effusions (MPEs) which use the visual analogue scale for dyspnea (VASD) as an outcome measure, the MID has not been established. METHODS: Patients with suspected MPE undergoing a pleural procedure recorded their baseline VASD and their post-procedure VASD (24 hours after the pleural drainage), and in parallel assessed their breathlessness on a 7 point Likert scale. FINDINGS: The mean decrease in VASD in patients with a MPE reporting a 'small but just worthwhile decrease' in their dyspnea (i.e. equivalent to the MID) was 19mm (95% CI 14-24mm). The mean drainage volume required to produce a change in VASD of 19mm was 760ml. INTERPRETATION: The mean MID for the VASD in patients with a MPE undergoing a pleural procedure is 19mm (95% CI 14-24mm). Thus choosing an improvement of 19mm in the VASD would be justifiable in the design and analysis of future MPE studies.

BACKGROUND: Intercostal chest drain (ICD) insertion is considered a core skill for the general physician. Recent guidelines have highlighted the risks of this procedure, while UK medical trainees have reported a concurrent decline in training opportunities and confidence in their procedural skills. OBJECTIVES: We explored clinicians' attitudes, experience and knowledge relating to pleural interventions and ICD insertion in order to determine what changes might be needed to maintain patient safety and quality of training. METHODS: Consultants and trainees delivering general medical services across five hospitals in England were invited to complete a questionnaire survey over a 5-week period in July and August 2014. RESULTS: 117 general physicians (32.4% of potential participants; comprising 31 consultants, 48 higher specialty trainees, 38 core trainees) responded. Respondents of all grades regarded ICD insertion as a core procedural skill. Respondents were asked to set a minimum requirement for achieving and maintaining independence at ICD insertion; however, only 25% of higher specialty trainees reported being able to attain this self-imposed standard. A knowledge gap was also revealed, with trainees managing clinical scenarios correctly in only 51% of cases. CONCLUSIONS: Given the disparity between clinical reality and what is expected of the physician-in-training, it is unclear whether ICD insertion can remain a core procedural skill for general physicians. Consideration should be given to how healthcare providers and training programmes might address issues relating to clinical experience and knowledge given the implications for patient safety and service provision.
