Green Pleural Effusion in a Patient With Hodgkin Lymphoma.

A 35-year-old man presented with fever, drenching sweats, severe shoulder pain, and bilateral cervical and supraclavicular lymphadenopathy on physical exam. Computed tomography of the chest showed hilar, mediastinal, and supraclavicular adenopathy, multiple pulmonary nodules, and a left-sided pleural effusion. Thoracentesis revealed a green pleural effusion. After a systematic workup and core biopsy analysis of a supraclavicular lymph node, the patient was diagnosed with Hodgkin lymphoma. The green pleural effusion fluid was attributed to increased pleural fluid viscosity rarely seen in patients with lymphoma.

Diagnosis of Pleural Mesothelioma: Is Everything Solved at the Present Time?

Ranked high in worldwide growing health issues, pleural diseases affect approximately one million people globally per year and are often correlated with a poor prognosis. Among these pleural diseases, malignant pleural mesothelioma (PM), a neoplastic disease mainly due to asbestos exposure, still remains a diagnostic challenge. Timely diagnosis is imperative to define the most suitable therapeutic approach for the patient, but the choice of diagnostic modalities depends on operator experience and local facilities while bearing in mind the yield of each diagnostic procedure. Since the analysis of pleural fluid cytology is not sufficient in differentiating historical features in PM, histopathological and morphological features obtained via tissue biopsies are fundamental. The quality of biopsy samples is crucial and often requires highly qualified expertise. Since adequate tissue biopsy is essential, medical or video-assisted thoracoscopy (MT or VATS) is proposed as the most suitable approach, with the former being a physician-led procedure. Indeed, MT is the diagnostic gold standard for malignant pleural pathologies. Moreover, this medical or surgical approach can allow diagnostic and therapeutic procedures: it provides the possibility of video-assisted biopsies, the drainage of high volumes of pleural fluid and the administration of sterile calibrated talcum powder under visual control in order to achieve pleurodesis, placement of indwelling pleural catheters if required and in a near future potential intrapleural therapy. In this context, dedicated diagnostic pathways remain a crucial need, especially to quickly and properly diagnose PM. Lastly, the interdisciplinary approach and multidisciplinary collaboration should always be implemented in order to direct the patient to the best customised diagnostic and therapeutic pathway. At the present time, the diagnosis of PM remains an unsolved problem despite MDT (multidisciplinary team) meetings, mainly because of the lack of standardised diagnostic work-up. This review aims to provide an overview of diagnostic procedures in order to propose a clear strategy.

Etiology of exudative pleural effusion among adults: differentiating between tuberculous and other causes, a multicenter prospective cohort study.

Objectives: Exudative pleural effusions have a broad etiology and usually necessitate further investigative workup, including invasive procedures. This study aimed to evaluate and compare the demographic, clinical, and biochemical characteristics of tuberculous, malignant, and chronic inflammatory pleural effusions. Methods: This is a 2-year prospective cohort study of patients referred for medical thoracoscopy with an exudative pleural effusion. Results: A total of 159 patients were enrolled in the study, with a mean age of 42.49 ± 13.8 years and the majority being males 121 (76.1%). As expected, patients with tuberculous effusions were significantly younger than those with non-tuberculous effusions (37.7 ± 10.9 vs 49.1 ± 14.9, P <0.001). Serum analysis showed significantly lower white blood cell count (7.5 × 109/L ± 2.7 vs 9.0 × 109/L ± 3.3, P = 0.004), higher total protein (76.2 g/dL ± 10.1 vs 70.2 g/dL ± 8.9, P <0.001), and higher median C-reactive protein (median 77.5, interquartile range 51-116 vs median 40.5, interquartile range 8-127, P <0.001) among tuberculous compared with non-tuberculosis effusions. Conclusions: Our study validates previous findings showing similar results in patients with tuberculous pleural effusions. A predictive model incorporating different demographic and clinical/laboratory characteristics may be useful in the early etiologic characterization of exudative pleural effusion.

Common Ultrasound-Guided Procedures.

Ultrasound guidance is fundamental to procedural safety and success. For many emergency department (ED) procedures, the use of ultrasound improves first-pass success rate, time-to-completion, and complication rate when compared with traditional landmark-based techniques. Once learned, the general principles of ultrasound guidance may be adapted across a broad range of bedside procedures.

The CIRrhotic Ascites Severity (CIRAS) model predicts hepatic hydrothorax at all stages of ascites.

BACKGROUND: Hepatic hydrothorax (HH) is a rare but severe manifestation of cirrhotic ascites. Whether HH development relates to ascites severity is uncertain and simple clinical models to predict HH from all stages of ascites are missing. The recently published CIRrhotic Ascites Severity (CIRAS) model using only ascites-related variables may serve this purpose. AIM: We investigated if the CIRAS model within one year predicts the development of HH requiring thoracentesis in patients with cirrhosis and ascites. METHODS: We used data from 1090 patients with cirrhosis and all severities of ascites enrolled in three randomized clinical trials with available CIRAS model scores and no history of HH. Fine and Gray regression was applied to estimate the CIRAS model's ability to predict HH. RESULTS: Thirty-five patients developed HH requiring thoracentesis. The CIRAS model stratified patients at different risks for HH and increasing CIRAS score was associated with a higher risk for HH (sHR 1.49 [95% CI: 1.19-1.86]). The CIRAS model's discriminatory ability achieved an AUC of 0.67 (95% CI: 0.56-0.77); higher than of the cirrhosis severity scores Child-Pugh and MELD variants. CONCLUSION: The CIRAS model predicts the development of HH in cirrhosis patients with any grade of ascites, suggesting a potential for improved pre-emptive HH management. This complements the general movement towards personalised treatments and care.

The Chest Pain That Never Went Away: A Case of Complex Cardiopulmonary Pathologies in a 64-Year-Old Caucasian Male.

Chest pain is a common and complex symptom that can arise from various etiologies, ranging from benign musculoskeletal conditions to life-threatening cardiovascular events. It is a hallmark symptom of myocardial infarction, angina, and other ischemic heart diseases, necessitating prompt and thorough evaluation. Ongoing chest pain post-procedures and medication administration presents a diagnostic challenge, as it may be indicative of an exacerbation of underlying conditions. We present the case of a 64-year-old Caucasian male who initially presented with severe and persistent chest pain suggestive of an anterior wall ST-elevation myocardial infarction (STEMI). He had a history of coronary artery disease and had recently undergone cardiac catheterization. Despite prompt administration of nitroglycerin and aspirin, the patient's symptoms persisted, prompting emergent percutaneous coronary intervention (PCI). Subsequent to PCI, ongoing chest discomfort persisted, prompting further investigation, which revealed a concurrent lung mass and nodules on imaging. Additional interventions, including repeated PCI procedures and thoracentesis, were undertaken. Unfortunately, the patient's clinical course rapidly deteriorated, culminating in cardiac arrest and unsuccessful resuscitative efforts. This case highlights the complexities inherent in managing intricate cardiovascular conditions and emphasizes the critical importance of maintaining vigilance for concomitant pathologies.

Bilothorax as a complication of endoscopic retrograde cholangiopancreatography: A rare case report and literature review.

INTRODUCTION: Bilothorax is a rare and poorly documented condition in the medical literature, with following hepatobiliary procedures being the most common cause. We present a case of bilothorax following endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. CASE PRESENTATION: A 71-year-old woman with a history of prior percutaneous biliary stone removals presented with Charcot's triad and was diagnosed with cholangitis due to a distal common bile duct stone. She underwent ERCP with successful stone extraction and stent placement. Two days later, she developed a right-sided pleural effusion diagnosed as a post-ERCP bilothorax. She was treated with thoracentesis and antibiotics, and her condition significantly improved. After 15 days, she was discharged, and a one-month follow-up showed no complications or recurrence. CLINICAL DISCUSSION: Bile is a potent chemo irritant that can cause adhesive pleurodesis. Besides, accompanying cholangitis can lead to pleural infection and empyema. In this patient, early diagnosis leading to timely pleural drainage decisions helped avoid potential consequences. CONCLUSION: Post-ERCP bilothorax is a rare complication but can lead to severe consequences. Nonoperative management by pleural drainage is a safe and effective strategy if diagnosis is made early, helping patients avoid more invasive interventions.

Gravity- vs Wall Suction-Driven Large-Volume Thoracentesis: A Randomized Controlled Study.

BACKGROUND: Prior studies have found no differences in procedural chest discomfort for patients undergoing manual syringe aspiration or drainage with gravity after thoracentesis. However, whether gravity drainage could protect against chest pain due to the larger negative-pressure gradient generated by wall suction has not been investigated. RESEARCH QUESTION: Does wall suction drainage result in more chest discomfort compared with gravity drainage in patients undergoing large-volume thoracentesis? STUDY DESIGN AND METHODS: In this multicenter, single-blinded, randomized controlled trial, patients with large free-flowing effusions of ≥ 500 mL were assigned at a 1:1 ratio to wall suction or gravity drainage. Wall suction was performed with a suction system attached to the suction tubing and with vacuum pressure adjusted to full vacuum. Gravity drainage was performed with a drainage bag placed 100 cm below the catheter insertion site and connected via straight tubing. Patients rated chest discomfort on a 100-mm visual analog scale before, during, and after drainage. The primary outcome was postprocedural chest discomfort at 5 min. Secondary outcomes included measures of postprocedure chest discomfort, breathlessness, procedure time, volume of fluid drained, and complication rates. RESULTS: Of the 228 patients initially randomized, 221 were included in the final analysis. The primary outcome of procedural chest discomfort did not differ significantly between the groups (P = .08), nor did the secondary outcomes of postprocedural discomfort and dyspnea. Similar volumes were drained in both groups, but the procedure duration was longer in the gravity arm by approximately 3 min. No differences in rate of pneumothorax or reexpansion pulmonary edema were noted between the two groups. INTERPRETATION: Thoracentesis via wall suction and gravity drainage results in similar levels of procedural discomfort and dyspnea improvement.

The effect of pleural drainage on pulse oximetry in a post-operative thoracic surgery population.

BACKGROUND: Pleural effusions in post-operative thoracic surgery patients are common. Effusions can result in prolonged hospitalizations or readmissions, with prior studies suggesting mixed effects of pleural drainage on hypoxia. We aimed to define the impact of pleural drainage on pulse oximetry (SpO2) in post-thoracic surgery patients. METHODS: A retrospective study of post-operative thoracic surgery patients undergoing pleural drainage was performed. SpO2 and supplemental oxygen (FiO2) values were recorded at pre- and post-procedure. The primary outcome was difference in pre-procedural and post-procedural SpO2. RESULTS: We identified 95 patients with a mean age of 65 (SD - 13.8) years undergoing 122 pleural drainage procedures. Mean drainage volume was 619 (SD-423) mL and the majority of procedures (88.5 %) included a drainage of <1000 mL. SpO2 was associated with an increase from 94.0 % (SD-2.6) to 97.3 % (SD-2.0) at 24-h (p < 0.0001). FiO2 was associated with a decrease from 0.31 (SD-0.15) to 0.29 (SD-0.12) at 24-h (p = 0.0081). SpO2/FiO2 was associated with an increase from 344.5 (SD-99.0) to 371.9 (SD-94.7) at 24-h post-procedure (p < 0.0001). CONCLUSIONS: Pleural drainage within post-operative thoracic surgery patients offers statistically significant improvements in oxygen saturation by peripheral pulse oximetry and oxygen supplementation; however the clinical significance of these changes remains unclear. Pleural drainage itself may be requested for numerous reasons, including diagnostic (fevers, leukocytosis, etc.) or therapeutic (worsening dyspnea) evaluation. However, pleural drainage may offer minimal clinical impact on pulse oximetry in post-operative thoracic surgery patients.

A Multidisciplinary Curriculum to Standardize Chest Procedures Training for Trainees in General Surgery, Emergency Medicine, and Critical Care.

Introduction: Critical care, emergency medicine, and surgical trainees frequently perform surgical and Seldinger-technique tube thoracostomy, thoracentesis, and thoracic ultrasound. However, approaches to teaching these skills are highly heterogeneous. Over 10 years, we have developed a standardized, multidisciplinary curriculum to teach these procedures. Methods: Emergency medicine residents, surgical residents, and critical care fellows, all in the first year of their respective programs, underwent training in surgical and Seldinger chest tube placement and securement, thoracentesis, and thoracic ultrasound. The curriculum included preworkshop instructional videos and 45-minute in-person practice stations (3.5 hours total). Sessions were co-led by faculty from emergency medicine, thoracic surgery, and pulmonary/critical care who performed real-time formative assessment with standardized procedural steps. Postcourse surveys assessed learners' confidence before versus after the workshop in each procedure, learners' evaluations of faculty by station and specialty, and the workshop overall. Results: One hundred twenty-three trainees completed course evaluations, demonstrating stable and positive responses from learners of different backgrounds taught by a multidisciplinary group of instructors, as well as statistically significant improvement in learner confidence in each procedure. Over time, we have made incremental changes to our curriculum based on feedback from instructors and learners. Discussion: We have developed a unique curriculum designed, revised, and taught by a multidisciplinary faculty over many years to teach a unified approach to the performance of common chest procedures to surgical, emergency medicine, and critical care trainees. Our curriculum can be readily adapted to the needs of institutions that desire a standardized, multidisciplinary approach to thoracic procedural education.

Tuberculous Pericardial Effusion With Pleural Effusion in an Indian Female: A Rare Case.

Tuberculosis can present at various extrapulmonary sites. However, even in endemic countries, concomitant involvement of different sites in the same patient is rarely reported. Further, tuberculous pericarditis represents a fraction of all tuberculosis infections and is an uncommon form of extrapulmonary tuberculosis. In underdeveloped nations, it is the most frequent cause of massive pericardial effusion. Additionally, it is the most common cause of constrictive pericarditis in adults, which has a high death rate and a poor prognosis. Furthermore, concomitant pleural effusion due to Mycobacterium tuberculosis is infrequently reported. Herein, a case of concomitant pericardial and left-sided pleural effusion in an Indian female is reported. She came with complaints of breathlessness, chest pain, night sweats, and loss of appetite. A diagnostic pleural thoracentesis and pericardiocentesis helped establish the diagnosis, and she was commenced on antituberculous treatment for 168 days.

Ultrasound-Assisted and Ultrasound-Guided Thoracentesis: An Educational Review.

Thoracentesis is one of the most important invasive procedures in the clinical setting. Particularly, thoracentesis can be relevant in the evaluation of a new diagnosed pleural effusion, thus allowing for the collection of pleural fluid so that laboratory tests essential to establish a diagnosis can be performed. Furthermore, thoracentesis is a maneuver that can have therapeutic and palliative purposes. Historically, the procedure was performed based on a physical examination. In recent years, the role of ultrasound has been established as a valuable tool for assistance and guidance in the thoracentesis procedure. The use of ultrasound increases success rates and significantly reduces complications. The aim of this educational review is to provide a detailed and sequential examination of the procedure, focusing on the two main modalities, the ultrasound-assisted and ultrasound-guided form.

Successful Treatment of Congenital Chylothorax by Early Use of Prednisolone: A Case Report.

Congenital chylothorax is the most common form of pleural effusion during the neonatal period; however, no treatment strategy exists. The pathogenesis and etiology of this disease are not fully understood; hence, several cases are difficult to treat. Some patients with chylothorax may not survive due to severe respiratory distress. Prednisolone (PSL) is sometimes used to treat congenital chylothorax but is rarely used in the early postnatal period. In this report, we describe a neonate with prenatal pleural effusion who was successfully treated with PSL from day one after requiring endotracheal intubation and ventilator management due to a postnatal diagnosis of chylothorax. The patient was extubated at four days of age, weaned from the ventilator at 10 days of age, and discharged home at 40 days of age after a total of 10 days of administration. Although the mechanism of action of PSL in chylothorax is unknown, and because it is a steroid, side effects such as gastrointestinal perforation and susceptibility to infection should be noted. The present case suggests the utility of early PSL administration for the treatment strategy of congenital chylothorax.

Re-expansion Pulmonary Edema (REPE) Following Thoracentesis: Is Large-Volume Thoracentesis Associated with Increased Incidence of REPE?

PURPOSE: To determine the safety and efficacy associated with drainage volumes greater than 1,500 mL in a single, unilateral thoracentesis without pleural manometry measurements. MATERIALS AND METHODS: This retrospective, single-institution study included 872 patients (18 years and older) who underwent ultrasound-guided thoracentesis. Patient and procedures data were collected including demographics, number of and laterality of thoracenteses, volume and consistency of fluid removed, and whether clinical or radiologic evidence of re-expansion pulmonary edema (REPE) developed within 24 h of thoracentesis. Fisher's exact test was used to test the significance of the relationship between volume of fluid removed and evidence of REPE. RESULTS: A total of 1376 thoracenteses were performed among the patients included in the study. The mean volume of fluid removed among all procedures was 901.1 mL (SD = 641.7 mL), with 194 (14.1%) procedures involving the removal of ≥ 1,500 mL of fluid. In total, six (0.7%) patients developed signs of REPE following thoracentesis, five of which were a first-time thoracentesis. No statistically significant difference in incidence of REPE was observed between those with ≥ 1,500 mL of fluid removed compared to those with < 1,500 mL of fluid removed (p-value = 0.599). CONCLUSIONS: Large-volume thoracentesis may safely improve patients' symptoms while preventing the need for repeat procedures.

Resident physician training in bedside pleural procedures: A one-year experience at a teaching hospital.

BACKGROUND AND OBJECTIVE: This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects. MATERIALS AND METHODS: The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023. RESULTS: 463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications. CONCLUSION: Bedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety.

The Clinical and Economic Implications of Different Treatment Pathways for Patients With Rapidly Recurrent Malignant Pleural Effusion.

BACKGROUND: Malignant pleural effusion (MPE) is a common cancer complication. Clinical and economic implications of different recurrent MPE treatment pathways have not been evaluated fully. RESEARCH QUESTION: What clinical outcomes, complications, health care resource use, and costs are associated with various rapidly recurrent MPE treatment pathways? STUDY DESIGN AND METHODS: This retrospective cohort study using Surveillance, Epidemiology and End Results Medicare data (2011-2015) included patients 66 to 90 years of age with rapidly recurrent MPE. Rapid recurrence was defined as receipt of a second pleural procedure within 14 days of the first thoracentesis, including nondefinitive repeated thoracentesis or a definitive treatment option including chest tube, indwelling pleural catheter (IPC), or thoracoscopy. RESULTS: Among 8,378 patients with MPE, 3,090 patients (36.9%) had rapidly recurrent MPE (mean ± SD age, 75.9 ± 6.6 years; 45.6% male; primary cancer, 62.9% lung and 37.1% other). Second pleural procedures were nondefinitive thoracentesis (62.3%), chest tube (17.1%), IPC (13.2%), or thoracoscopy (7.4%). A third pleural procedure was required more frequently if the second pleural procedure was nondefinitive thoracentesis vs chest tube placement, IPC placement, or thoracoscopy (70.3% vs 44.1% vs 17.9% vs 14.4%, respectively). The mean number of subsequent pleural procedures over the patient's lifetime varied significantly among the procedures (1.74, 0.82, 0.31, and 0.22 procedures for patients receiving thoracentesis, chest tube, IPC, and thoracoscopy, respectively; P < .05). Average total costs after the second pleural procedure to death adjusted for age at primary cancer diagnosis, race, year of second pleural procedure, Charlson comorbidity index, cancer stage at primary diagnosis, and time from primary cancer diagnosis to diagnostic thoracentesis were lower with IPC ($37,443; P < .0001) or chest tube placement ($40,627; P = .004) vs thoracentesis ($47,711). Patients receiving thoracoscopy ($45,386; P = .5) incurred similar costs as patients receiving thoracentesis. INTERPRETATION: Early definitive treatment was associated with fewer subsequent procedures and lower costs in patients with rapidly recurrent MPE.

Non-traumatic Diaphragmatic Eventration With Extrapulmonary Tuberculosis Presenting As Pleural Effusion in an Indian Male: The First Report of Its Type.

Tuberculosis is rampant in endemic countries. Extrapulmonary tuberculosis, like pleural effusion, is infrequently reported in outpatient departments. However, diaphragmatic eventration is rare and is not reported in active tuberculosis. Herein, the first-of-its-type case of a diaphragmatic eventration with tuberculous right pleural effusion in an Indian male is presented. The diagnosis was challenging and achieved through radiometric investigations and diagnostic pleural tapping. He was put on an anti-tuberculous treatment based on his weight.

Atypical Pleural Effusion in an Immunocompetent Patient With Valley Fever: A Case Study and Review of the Literature.

Valley fever is a fungal infection, commonly of the lungs, caused by Coccidioides immitis or Coccidioides posadasii. This disease is endemic to the southwestern United States, Central America, and South America. Infected individuals are typically asymptomatic but may develop community-acquired pneumonia. On rare occasions, coccidioidomycosis can present with severe complications in addition to the pulmonary manifestation. In this study, a 58-year-old immunocompetent male presented to the Emergency Department with a cough, night sweats, and pleuritic chest pain. Despite the administration of broad-spectrum antimicrobials, he developed a large right pleural effusion that did not resolve following thoracentesis. Serology was positive for Coccidioides, and the patient was referred to a thoracic surgeon due to persistent effusion. It is rare for patients with coccidiomycosis to develop a large pleural effusion requiring surgical intervention, especially in immunocompetent individuals. This case highlights the importance of monitoring patients with unresolved acute pneumonia in endemic areas and considering Coccidioides as a possible etiology.
