Combined medical-interventional approaches for the management of complex fungal balls: a case series as a viable alternative in non-surgical patients.

Intracavitary pulmonary aspergilloma is a persistent and life-threatening infection that carries a mortality rate of up to 15%. It occurs when Aspergillus species gain entry to an existing lung cavity. In the absence of definitive treatment, patients may succumb to severe complications such as massive hemoptysis, cachexia, or secondary infections. Aspergillomas often show limited response to antifungal medications, mainly due to insufficient drug concentrations within the cavities. Surgery is frequently the preferred treatment option, but it poses significant risks, and many individuals are ineligible due to underlying health issues. We present the most extensive non-surgical fungal ball cohort to date, managed using an innovative multimodal strategy that combines antifungal therapy before and after bronchoscopic debulking. This was a cross-sectional observational study. For those who cannot undergo surgery, our medical center has pioneered a multimodal approach to aspergilloma resection. This approach combines bronchoscopic endoscopy with antifungal therapy and has been applied successfully to more than 18 patients that are presented in this series. The median age of the cohort was 58 years (range: 32-73), with an equal sex distribution. The mean percent predicted FEV1 was 65.3%. The mean follow-up duration was 3.6 years (range: 0.5-10 years). The cohort receiving antifungals systematically prior to debridement showed a reduction of the pre-existing cavity (40.38 mm versus 34.02 mm, p = 0.021). Across the 18 patients during the follow-up period, 94% remained recurrence-free (defined by symptoms and radiology). Our study fills a critical knowledge gap regarding the significance of initiating antifungal treatment before bronchoscopic debulking and presents a viable approach in these cases for which there is a current unmet therapeutic need.

The use of both medical and interventional methods to treat difficult fungal masses: A collection of cases showing efficacy for patients who can't undergo surgeryIntracavitary pulmonary aspergilloma is a serious and potentially deadly infection with a death rate of up to 15%. It happens when certain types of fungi invade existing lung cavities. Without proper treatment, patients may experience severe complications like heavy bleeding from the lungs, weight loss, or other infections. Traditional antifungal medications often don't work well because they can't reach high enough concentrations in the cavities. Surgery is usually the best option, but it's risky and not possible for many due to other health problems. Our study introduces a new way to treat aspergilloma without surgery. We've treated a significant number of patients using a combination of antifungal drugs and a procedure called bronchoscopic debulking. This involves removing the fungal growth using a thin tube inserted through the airways. Our research involved observing 18 patients treated this way. They were mostly middle-aged, with equal numbers of men and women. Their lung function was moderately impaired, and we followed them for an average of 3.6 years. We found that giving antifungal drugs before the debulking procedure helped reduce the size of the cavities. After treatment, almost all patients remained free of symptoms and signs of recurrence. This study highlights the importance of starting antifungal therapy before bronchoscopic debulking and offers a promising option for patients who can't have surgery.

Protocol for the Stather Canadian Outcomes Registry for Chest ProcedurEs (SCOPE).

INTRODUCTION: The Stather Canadian Outcomes registry for chest ProcedurEs (SCOPE registry) is a Canadian multicentre registry of chest procedures. METHODS AND ANALYSIS: The SCOPE registry is designed as a multicentre prospective database of specific bronchoscopic or other pulmonary procedures. Each procedure of interest will be associated with a registry module, and data capture designed to evaluate effectiveness of procedures on relevant patient outcomes. Participating physicians will be asked to enter data for all procedures performed in a given module. The anonymised dataset will be housed in a web-based electronic secure database. Specific modules included will be based on participating physician suggestions, capacity and consensus of the steering committee and relevance of hypotheses/research potential. ETHICS AND DISSEMINATION: The central registry is under approval from the Conjoint Health Research Ethics Board at the University of Calgary. We aim for registry data to lead to publication of manuscripts in international medical journals as the primary mode of dissemination. Data may also be used by local investigators for personal and/or institutional quality control purposes as well as to inform health policies. Data requests from non-participating investigators for use under ethics approved research protocols can be considered.

Initial Clinical Experience With a Flexible Peripheral 21-G Needle Device.

BACKGROUND: Bronchoscopic techniques can be used to safely sample peripheral lung nodules (PLN), and transbronchial needle aspiration (TBNA) can further increase the diagnostic yield. Current needle devices not necessarily designed for this indication have limitations. We report our initial experience with a new flexible nitinol peripheral TBNA needle specifically designed for such sampling. METHODS: Retrospective case review describing the first clinical cases performed with a commercially available 21-G peripheral TBNA device in 4 centers. RESULTS: Eleven different operators performed 40 procedures for PLNs of a mean size of 35.1 mm (±18), and located 18.8 mm (±18.8) from the pleural surface, with 50% of them being present in the upper lobes. Bronchoscopists rated the use of the needle as good or excellent for reaching the PLN in 27/30 (90%) of cases. The TBNA sample was diagnostic in 18/40 cases (45%) overall and in 18/28 (64.3%) of cases where a diagnosis on bronchoscopy was possible. No episode of pneumothorax, significant bleeding, hypoxemia, escalation of care, or other complications were noted. CONCLUSION: Our initial experience with a novel peripheral TBNA device appears safe and effective, and may offer technical advantages over other available devices. Additional studies will be required to confirm the role of this device in the approach to bronchoscopic sampling of parenchymal lung nodules.

Intrapleural Fibrinolysis for the Treatment of Indwelling Pleural Catheter-Related Symptomatic Loculations: A Multicenter Observational Study.

BACKGROUND: Indwelling pleural catheters (IPCs) are an effective option in the management of malignant pleural effusion. Up to 14% of patients with IPCs develop symptomatic pleural loculations causing ineffective fluid drainage and breathlessness. To our knowledge, this is the first study to describe intrapleural fibrinolytic therapy for IPC-related symptomatic loculations. METHODS: All patients who received intrapleural fibrinolytic therapy for symptomatic loculations between January 1, 2002, and June 30, 2014, in four established IPC centers were retrospectively included. Patient outcomes, treatment effectiveness, and adverse events were recorded. RESULTS: Sixty-six patients (mean age, 64.7 ± 14.2 years; 52% women) were included. Lung cancer (31.3%) and malignant pleural mesothelioma (20.3%) were the most common malignancies. Fibrinolytic instillation was performed in outpatient (61%) and inpatient settings. Tissue-plasminogen activator (n = 52), urokinase (n = 12), and streptokinase (n = 2) were used. The majority (69.7%) received only one fibrinolytic dose (range, one to six). Pleural fluid drainage increased in 93% of patients, and dyspnea improved in 83% following therapy. The median cumulative pleural fluid volume drained at 24 h posttreatment was 500 mL (interquartile range 300-1,034 mL). The area of opacity caused by pleural effusion on chest radiograph decreased from (mean, SD) 52% (14%) to 31% (21%) of the hemithorax (n = 13; P = .001). There were two cases of nonfatal pleural bleed (3%). CONCLUSIONS: Intrapleural fibrinolytic therapy can improve pleural fluid drainage and symptoms in selected patients with IPC and symptomatic loculation, but it carries a small risk of pleural bleeding. There is significant heterogeneity in its use currently, and further studies are needed to determine patient selection and optimal dosing regimen and to define its safety profile.

Severe airway injury due to alendronate aspiration.

Sequelae of foreign body aspiration can range from clinically silent and asymptomatic to immediate asphyxiation and death. Only two previous cases of bisphosphonate tablet aspiration have been reported. Ulcerative esophagitis, a known adverse effect of oral bisphosphonate formulations, occurs primarily with prolonged exposure of esophageal mucosa to the medication. Little is known about the effects of bisphosphonates on the airway mucosa. The authors present a case involving an 84-year-old woman who required multiple bronchoscopic debridements, intubation for airway protection and intensive care unit admission following airway injury believed to be due to delayed recognition of aspiration of an alendronate tablet.
