Patient-Reported Outcome Measures in Patients with and without Non-Expandable Lung Secondary to Malignant Pleural Effusion-A Single-Centre Observational Study.

Background: Malignant pleural effusion (MPE) affects up to 15% of patients with malignancy, and the prevalence is increasing. Non-expandable lung (NEL) complicates MPE in up to 30% of cases. However, it is not known if patients with malignant pleural effusion and NEL are more symptomatic in activities of daily living compared to patients with MPE with expandable lung.

Ultrasound in predicting improvement in dyspnoea after therapeutic thoracentesis in patients with recurrent unilateral pleural effusion.

Background: In patients with recurrent pleural effusion, therapeutic thoracentesis is one way of relief. Correct prediction of which patients will experience relief following drainage may support the management of these patients. This study aimed to assess the association between ultrasound (US) characteristics and a relevant improvement in dyspnoea immediately following drainage.

[Not Available].

The incidence of pleural disease is increasing and the mortality and morbidity is high. Many recent RCTs have resulted in evidence-based guidelines published in 2023, pointing towards a more individualized and specialized management. Most patients with pleural disease are admitted at the A and E but can be managed in outpatient clinics.

Ultrasound in the Diagnosis of Non-Expandable Lung: A Prospective Observational Study of M-Mode, B-Mode, and 2D-Shear Wave Elastography.

Background: Non-expandable lung (NEL) has severe implications for patient symptoms and impaired lung function, as well as crucial implications for the management of malignant pleural effusion (MPE). Indwelling pleural catheters have shown good symptom relief for patients with NEL; hence, identifying patients early in their disease is vital. With the inability of the lung to achieve pleural apposition following thoracentesis and the formation of a hydropneumothorax, traditionally, chest X-ray and clinical symptoms have been used to make the diagnosis following thoracentesis.

Clinical characteristics of chylothorax: results from the International Collaborative Effusion database.

Background: Chylothorax is an uncommon medical condition for which limited data are available regarding the contemporary aetiology, management and outcomes. The goal of this study was to better define these poorly characterised features.

Methods: The medical records of adult patients diagnosed with chylothorax at 12 centres across Europe, America and South Africa from 2009-2021 were retrospectively reviewed.

Additional Up-Front Thoracic Ultrasound in the Workup of Patients with Unilateral Pleural Effusion: A Prospective Observational Pilot Study.

Background: In patients with pleural effusion, specific ultrasound characteristics are associated with pleural malignancy.

Objectives: This study aimed to evaluate the added value of an additional, up-front, systematic thoracic ultrasound (TUS) to standard imaging in patients with unilateral pleural effusion of unknown cause in a clinical setting.

Methods: In a prospective observational pilot study, patients referred for workup and thoracentesis of a unilateral pleural effusion received up-front TUS following a set protocol in addition to available imaging and US guiding the thoracentesis or diagnostic puncture.

Inhaled Corticosteroids in Patients with Chronic Obstructive Pulmonary Disease and Risk of Acquiring Infection. A Multiregional Epidemiological Study.

Background: Inhaled corticosteroids (ICS) are associated with an increased risk of clinical pneumonia among patients with chronic obstructive pulmonary disease (COPD). It is unknown whether the risk of microbiologically verified pneumonia such as pneumococcal pneumonia is increased in ICS users.

Methods: The study population consists of all COPD patients followed in outpatient clinics in eastern Denmark during 2010-2017.

Prediction of Time to Next Therapeutic Thoracentesis and Identification of Risk Factors of Rapid Pleural Fluid Recurrence: A Prospective Observational Study.

Background: The value of pre-booked repeated thoracentesis in patients with recurrent pleural effusion is reliant on the estimation of time to next drainage. Identifying factors associated with rapid pleural fluid recurrence could be supportive.

Objective: We aimed to evaluate the ability of the patient and physician to predict the time to next therapeutic thoracentesis and to identify characteristics associated with rapid pleural fluid recurrence.

Suspected Lung Cancer with Suspicious Liver Lesions: Diagnostic Yield and Safety of Same-Day Bronchoscopy and Liver Biopsy in the Hands of a Pulmonologist.

Background: Bronchoscopy and endobronchial ultrasound (EBUS) are standard procedures for the diagnosis and staging of patients suspected of lung cancer. If the patient simultaneously presents with suspicious liver lesions, it is tradition to refer the patient to a radiologist for ultrasound-guided percutaneous liver biopsy.

Objective: The aim of this study was to investigate the results and complications when the pulmonologist performs all three procedures in the same setting.

Asymptomatic lung nodules in dental professionals: A diagnostic challenge.

Dental care workers are frequently exposed to various types of volatile organic and inorganic compounds. In addition to biological materials, these compounds include silica, heavy metals, and acrylic plastics. Such exposures may cause respiratory symptoms, but the nonspecific nature of these symptoms often means that the etiology is difficult to discern.

Positron emission tomography-computed tomography (PET-CT) in suspected malignant pleural effusion. An updated systematic review and meta-analysis.

The role of PET and integrated PET-CT in the diagnostic workup of suspected malignant pleural effusions is unknown. Earlier systematic reviews (published 2014 and 2015) both included pleural pathology without effusion, and reached contradictory conclusions. Five studies have been published since the latest review.

The prevalence of tumour markers in malignant pleural effusions associated with primary pulmonary adenocarcinoma: a retrospective study.

Background: Oncological treatment of primary pulmonary adenocarcinoma (AC) includes drugs targeting the pathways involving (PD-L1), (EGFR) mutation and (ALK). The aim of the study was to report the prevalence of these tumour markers in pleural fluid with cytology positive for pulmonary AC and the potential influence of volume pleural fluid tested.

Methods: We retrospectively reviewed all thoracenteses performed in a two-year period at our interventional unit at Department of Respiratory Medicine at Zealand University Hospital Naestved, Denmark.

[Malignant pleural effusion].

Malignant pleural effusion (MPE) is a common condition, often associated with a high level of symptoms. In this review, several palliative treatments for symptomatic MPE are summarised, including repeated thoracentesis, pleurodesis and insertion of indwelling pleural catheters. Choice of treatment depends on patient symptoms, life expectancy, pleural fluid production, expected effect of oncological treatment, whether trapped lung is suspected or not, and patient preferences.

Asymptomatic pleural thickening with effusion as the only manifestation of IgG4-related disease.

Immunoglobulin G4 (IgG4)-related disease is a systemic fibroinflammatory disorder that can affect almost any tissue. Isolated IgG4 pleural disease is a rare manifestation and, when present, is usually described in patients presenting with dyspnoea. We present a case of asymptomatic isolated IgG4 pleural effusion and highlight that IgG4-related disease should be remembered as a differential diagnosis in patients with pleural effusion and pleural thickening, even if asymptomatic and without any other organ involvement.

Pleural epithelioid hemangioendothelioma mimicking pleural empyema: A case report.

Malignant pleural effusion is an important and difficult differential diagnosis to pleural empyema. Epithelioid hemangioendothelioma is an uncommon vascular tumor, which typically occurs in liver, lung or bone. We present an extremely rare case of primary pleural epithelioid hemangioendothelioma mimicking pleural empyema.

Aspiration of Pericardial Effusion Performed with EUS-B-FNA in Suspected Lung Cancer.

Ultrasound-guided needle aspiration via the esophagus using the endobronchial endoscope (EUS-B-FNA) is increasingly being performed by the pulmonologist for the diagnosis of lung cancer, but we have little experience and data available in the literature especially with respect to staging of the disease. We present 2 cases of EUS-B-guided aspiration of malignant pericardial effusion performed in the same setting as bronchoscopy and endobronchial ultrasound. No complications were observed.
