Management of malignant pleural effusion in Italian clinical practice: a nationwide survey.

BACKGROUND: Pleural disease (PD), particularly malignant pleural effusion (MPE), is a common cause of hospital admission and its prevalence is rising worldwide. Recent advances in diagnostic and therapeutic options, such as Indwelling Pleural Catheters (IPCs), have simplified PD treatment, allowing an effective outpatients management. Therefore, dedicated pleural services can improve PD care, guaranteeing specialized management and optimizing time and cost. We aimed to provide an overview on MPE management in Italy, mainly focused on distribution and characteristics of pleural services and IPCs use. METHODS: A nationwide survey, endorsed by the Italian Thoracic Society, was distributed by email to members of selected subgroups in 2021. RESULTS: Ninety (23%) members replied, most of whom being pulmonologists (91%). MPE resulted the most common cause of pleural effusion and was managed with heterogenous approaches, including talc pleurodesis via slurry (43%), talc poudrage (31%), repeated thoracentesis (22%) and IPCs insertion (2%). The setting of IPC insertion was inpatient care in 48% of cases, with a predominance of draining frequency every other day. IPC management mainly relied on caregivers (42%). The presence of a pleural service was reported by 37% of respondents. CONCLUSIONS: The present study provides an extensive overview of MPE management in Italy, showing a highly heterogeneous approach, a scarce prevalence of out-patient pleural services, and a still limited adoption of IPCs, mainly due to lack of dedicated community care systems. This survey emphasizes the need of promoting a higher spreading of pleural services and an innovative healthcare delivery with more favourable cost-benefit ratio.

Percutaneous transthoracic catheter drainage for lung abscess: a systematic review and meta-analysis.

OBJECTIVES: To evaluate the outcomes of patients receiving image-guided percutaneous catheter drainage (PCD) for lung abscesses in terms of treatment success, major complications, and mortality as well as the predictors of those outcomes. METHODS: Embase and OVID-MEDLINE databases were searched to identify studies on lung abscesses treated with PCD that had extractable outcomes. The outcomes were pooled using a random-intercept logistic regression model. Multivariate Firth's bias-reduced penalised-likelihood logistic regression analyses were performed to identify predictors of treatment success and complications. Methodological quality was assessed by summing scores of binary responses to items regarding selection, ascertainment of exposure and outcome, causality of follow-up duration, and reporting. RESULTS: From 26 studies with acceptable methodological quality (median score, 4; range, 3-5), 194 patients were included. The pooled rates of treatment success and major complications were 86.5% (95% confidence interval [CI], 78.5-91.8%; I2 = 23%) and 8.1% (95% CI, 4.1-15.3%; I2 = 26%), respectively. Four patients eventually died from uncontrolled lung abscesses (pooled rate, 1.5%; 95% CI, 0.2-11.1%; I2 = 36%). Malignancy-related abscess (odds ratio [OR], 0.129; 95% CI, 0.024-0.724; p = .022) and the occurrence of a major complication (OR, 0.065; 95% CI, 0.02-0.193; p < .001) were significant predictors of treatment failure. Traversing normal lung parenchyma was the only significant risk factor for major complications (OR, 27.69; 95% CI, 7.196-123.603; p < .001). CONCLUSION: PCD under imaging guidance was effective for lung abscess treatment, with a low complication rate. Traversal of normal lung parenchyma was the sole risk factor for complications, and malignancy-related abscesses and the occurrence of major complications were predictors of treatment failure. KEY POINTS: • The pooled treatment success rate of PCD for lung abscess was reasonably high (86.5%); malignancy-related abscesses and the occurrence of a major complication were predictors of treatment failure. • The pooled rate of percutaneous transthoracic catheter drainage-related major complications was 8.1% and traversing normal lung parenchyma by the catheter was the only risk factor. • The pooled mortality rate from uncontrolled lung abscesses with percutaneous transthoracic catheter drainage was low.

Classification and analysis of outcome predictors in non-critically ill COVID-19 patients.

BACKGROUND: Early detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected patients who could develop a severe form of COVID-19 must be considered of great importance to carry out adequate care and optimise the use of limited resources. AIMS: To use several machine learning classification models to analyse a series of non-critically ill COVID-19 patients admitted to a general medicine ward to verify if any clinical variables recorded could predict the clinical outcome. METHODS: We retrospectively analysed non-critically ill patients with COVID-19 admitted to the general ward of the hospital in Pordenone from 1 March 2020 to 30 April 2020. Patients' characteristics were compared based on clinical outcomes. Through several machine learning classification models, some predictors for clinical outcome were detected. RESULTS: In the considered period, we analysed 176 consecutive patients admitted: 119 (67.6%) were discharged, 35 (19.9%) dead and 22 (12.5%) were transferred to intensive care unit. The most accurate models were a random forest model (M2) and a conditional inference tree model (M5) (accuracy = 0.79; 95% confidence interval 0.64-0.90, for both). For M2, glomerular filtration rate and creatinine were the most accurate predictors for the outcome, followed by age and fraction-inspired oxygen. For M5, serum sodium, body temperature and arterial pressure of oxygen and inspiratory fraction of oxygen ratio were the most reliable predictors. CONCLUSIONS: In non-critically ill COVID-19 patients admitted to a medical ward, glomerular filtration rate, creatinine and serum sodium were promising predictors for the clinical outcome. Some factors not determined by COVID-19, such as age or dementia, influence clinical outcomes.

Medical thoracoscopy without pleural fluid: How I do it.

Thoracoscopy is a commonly used minimally invasive procedure in the field of interventional pulmonology. While medical thoracoscopy is the widely preferred modality, modifications to the technique and expansion in the scope of its utility have always challenged the conventional approach. We describe a modified technique of medical thoracoscopy in absence of pleural effusion also known as dry thoracoscopy under sedation and local anaesthesia.

Novel use of the endobronchial ultrasound through esophagus (EUS-B): Diagnosis of thyroid lesions.

There is paucity in literature on the use of endobronchial ultrasound through esophagus (EUS-B) for the diagnosing thyroid gland lesions. We report the first case of colloid goiter diagnosed using EUS-B- FNA technique. A 77-year-old man presented with ophthalmic symptoms and an incidental finding of lung nodule on chest x-ray. The computed tomography of thorax revealed a left upper lobe nodule and an oval shaped left paratracheal lesion near left pole of thyroid gland. EUS-B- FNAC was performed which lead to the diagnosis of colloid goiter.

Percutaneous lung abscess drainage: revisiting the old gold standard.

Lung abscess is defined as the necrosis of lung tissue with cavity formation due to varied etiology. The treatment of lung abscesses is medical involving antibiotics and chest physiotherapy. The failure of medical line of management requires an invasive surgical or percutaneous approach for drainage and control of infection. While the literature is ample regarding the surgical approach, it is rather scarce on the percutaneous approach. The percutaneous drainage has been most studied with computed tomography guidance. With our case series we describe to the treatment of lung abscesses non-responsive to medical management, by a bedside minimally invasive ultrasound or fluoroscopy guided percutaneous drainage approach.

Convex probe endobronchial ultrasound guided transbronchial/transoesophageal fine needle aspiration (C-EBUS-TBNA/EUS-B FNA) of pleural lesions: A single center experience and review of literature.

The evaluation of pleural diseases has been well established. If pleurocentensis is non-diagnostic, the second investigation depending upon availability could be either closed pleural biopsy or image guided pleural biopsy or thoracoscopic pleural biopsy (medical or surgical). Pleural disease presenting as thickness/mass/nodule in the mediastinum is difficult to access through ultrasound or computed tomography and will need thoracoscopy. Thoracoscopy is an invasive procedure which can be difficult to perform in localized mediastinal pleural disease without effusion or poor health condition not suitable for general anesthesia. An alternative method that can be utilized is sampling of pleural lesion through convex probe endobronchial ultrasound (CEBUS) either through the central large airways or from esophagus if the lesions are in proximity. We present our center's experience in diagnosing pleural lesion using C-EBUS in 4 patients along with review of the literature.

A case report on expanding horizon of endobronchial ultrasound through esophagus.

Endobronchial ultrasound has revolutionized the field of bronchoscopy and has become one of the most important tools for the diagnosis of intrathoracic lymphadenopathy and para-bronchial structures. The reach of this technique has not been limited to these structures and pleural lesions have been at times accessible. To our knowledge, pleural fluid collections have not been accessed with endobronchial ultrasound (EBUS) through oesophageal approach and rationale behind using this approach. We report a case of 70 years old man who has been referred from physician for the EBUS in view of hilar mass with mediastinal lymphadenopathy with pleural effusion. The endobronchial ultrasound through oesophagus (EUS-B) was done for thoracocentesis and lymph node cytology evaluation and ultimately endobronchial biopsy of hilar mass was done as rapid on-site (ROSE) analysis of lymph node was suggestive of necrotic tissue. The cytology report of lymph node and pleural effusion was positive for malignant cells. The final diagnosis was metastatic poorly differentiating adeno-squamous carcinoma.

The Additional Value of Lower Respiratory Tract Sampling in the Diagnosis of COVID-19: A Real-Life Observational Study.

Background: Since December 2019, SARS-CoV-2 has been causing cases of severe pneumonia in China and has spread all over the world, putting great pressure on health systems. Nasopharyngeal swab (NPS) sensitivity is suboptimal. When the SARS-CoV-2 infection is suspected despite negative NPSs, other tests may help to rule out the infection. Objectives: To evaluate the yield of the lower respiratory tract (LRT) isolation of SARS-CoV-2. To evaluate the correlations between SARS-CoV-2 detection and clinical symptoms, and laboratory values and RSNA CT review scores in suspect patients after two negative NPSs. To assess the safety of bronchoscopy in this scenario. Method: A retrospective analysis of data from LRT sampling (blind nasotracheal aspiration or bronchial washing) for suspected COVID-19 after two negative NPS. Chest CT scans were reviewed by two radiologists using the RSNA imaging classification. Results: SARS-CoV-2 was detected in 14/99 patients (14.1%). A correlation was found between SARS-CoV2 detection on the LRT and the presence of a cough as well as with typical CT features. Typical CT resulted in 57.1% sensitivity, 80.8% accuracy and 92.3% NPV. Neither severe complications nor infections in the personnel were reported. Conclusions: In suspect cases after two negative swabs, CT scan revision can help to rule out COVID-19. In selected cases, with consistent CT features above all, LRT sampling can be of help in confirming COVID-19.

Predictors of Worse Prognosis in Young and Middle-Aged Adults Hospitalized with COVID-19 Pneumonia: A Multi-Center Italian Study (COVID-UNDER50).

Obesity as well as metabolic and cardiovascular comorbidities are established, significant predictors of worse prognosis in the overall COVID-19 population, but limited information is available on their roles in young and middle-aged adults (aged ≤ 50 years). The main objectives of the present Italian multi-center study were to describe clinical characteristics and role of selected prognostic predictors in a large cohort of young and middle-aged hospitalized patients. Nine pulmonology units, across north and center of Italy, were involved in this retrospective study. Comorbidities were classified according to their known or potential association with COVID-19. A total of 263 subjects were included. The prevalence of obesity was 25.9%, mechanical ventilation (MV) was needed in 27.7%, and 28 in-hospital deaths occurred (10.6%). Obesity and older age were the only independent, significant predictors for MV. Comorbidities, such as hypertension, diabetes, asthma, and increased D-dimer levels were significantly associated with higher mortality risk, regardless of age, body mass index, and MV. Obesity in young and middle-aged adults is a strong predictor of a more complicated COVID-19, without, however, evidence of a significant effect on in-hospital mortality. Selected comorbidities, including hypertension, diabetes and asthma, significantly impact survival even in a younger population, suggesting the need for prompt recognition of these conditions.

The Medical Concrete Cancer of the Lung: A Unique Case Report.

A 53-year-old 10 pack year smoker and concrete worker for 12 years presented to us with a lung mass proven to be small cell lung cancer on lung biopsy. An industrial terminology of concrete cancer already exists defining the wear and tear in concrete due to various interactions. The interactions of concrete and smoke on lung, predisposed and increased the risk of lung cancer probably as an additive effect which we label as the medical concrete cancer of the lung.

A novel procedure of endobronchial ultrasound-guided transbronchial needle aspiration for pulmonary parenchymal lesions: The ZUTAM technique.

Convex probe-endobronchial ultrasound (CP-EBUS) has been proven to be safe and accurate for identifying malignancy and granulomatous disease affecting the mediastinum and hilum. CP-EBUS can be used for intraparenchymal lesions also and has been shown to be efficacious. A subset of lesions particularly suited for CP-EBUS are those completely surrounded by lung parenchyma, centrally located, and typically close to but without an airway leading directly to them. We report a case of transbronchial needle aspiration (TBNA) done from a nodule of size 11 mm in the superior segment of the right lower lobe. EBUS-TBNA was done from this lesion, which was 5 mm away from the bronchus in the lung parenchyma with intervening normal lung tissue in between. TBNA was performed by compressing the abutting normal lung tissue, thus causing compression collapse of the intervening normal lung. We labeled this Zealous Unique Trans Arterial Maneuver as the "ZUTAM" technique.

Prolonged Low-Dose Methylprednisolone in Patients With Severe COVID-19 Pneumonia.

BACKGROUND: In hospitalized patients with coronavirus disease 2019 (COVID-19) pneumonia, progression to acute respiratory failure requiring invasive mechanical ventilation (MV) is associated with significant morbidity and mortality. Severe dysregulated systemic inflammation is the putative mechanism. We hypothesize that early prolonged methylprednisolone (MP) treatment could accelerate disease resolution, decreasing the need for intensive care unit (ICU) admission and mortality. METHODS: We conducted a multicenter observational study to explore the association between exposure to prolonged, low-dose MP treatment and need for ICU referral, intubation, or death within 28 days (composite primary end point) in patients with severe COVID-19 pneumonia admitted to Italian respiratory high-dependency units. Secondary outcomes were invasive MV-free days and changes in C-reactive protein (CRP) levels. RESULTS: Findings are reported as MP (n = 83) vs control (n = 90). The composite primary end point was met by 19 vs 40 (adjusted hazard ratio [aHR], 0.41; 95% CI, 0.24-0.72). Transfer to ICU and invasive MV were necessary in 15 vs 27 (P = .07) and 14 vs 26 (P = .10), respectively. By day 28, the MP group had fewer deaths (6 vs 21; aHR, 0.29; 95% CI, 0.12-0.73) and more days off invasive MV (24.0 ±â€…9.0 vs 17.5 ±â€…12.8; P = .001). Study treatment was associated with rapid improvement in PaO2:FiO2 and CRP levels. The complication rate was similar for the 2 groups (P = .84). CONCLUSION: In patients with severe COVID-19 pneumonia, early administration of prolonged MP treatment was associated with a significantly lower hazard of death (71%) and decreased ventilator dependence. Treatment was safe and did not impact viral clearance. A large randomized controlled trial (RECOVERY trial) has been performed that validates these findings. Clinical trial registration. ClinicalTrials.gov NCT04323592.

Esophageal ultrasound with ultrasound bronchoscope (EUS-B) guided left adrenal biopsy: Case report with review of literature.

A 45-year old man, chronic smoker with a pancoast tumor due to squamous cell carcinoma has been described. The initial diagnosis of lung carcinoma was based on a scant tissue so the exact cell typing was not possible. The initial treatment consisted of platinum based chemotherapy and radiotherapy. He developed a left adrenal lesion on treatment. There was a possibility of metachronous primary. Also, a large tissue sample was required for tumor markers. The lung mass was difficult to access and was static on treatment. A left adrenal biopsy was considered to be more appropriate. A novel approach for left adrenal lesion with esophageal ultrasound using ultrasound bronchoscope (EUS-B) was successfully performed. This article is aimed at describing the use of EUS-B for transdiaphragmatic structures.

Esophageal ultrasound with ultrasound bronchoscope (EUS-B) guided transvascular needle aspiration (TVNA).

We have described a 67-year-old man, diagnosed to have adenocarcinoma of lung by transvascular approach with esophageal ultrasound using ultrasound bronchoscope (EUS-B). To the best of our knowledge this is the first case where EUS-B has been used for transvascular fine needle aspiration cytology to diagnose lung carcinoma.

Multivitamin pill aspiration leading to hemorrhagic bronchial necrosis.

This article highlights the serious but reversible effects of multivitamin pill aspiration into the lungs. If diagnosed early and treated promptly the harmful effects of the pill constituents on the lungs and airways can be attenuated. An early bronchoscopy and a high index of suspicion is required in order not to miss these events. We have described a case of multivitamin pill aspiration in a young healthy male and the good response to early intervention.
