Objectives: To investigate the prevalence and recurrence rates of spontaneous pneumothorax (SP) in patients with diffuse cystic lung diseases (DCLDs).
Methods: We retrospectively identified and analyzed medical records of patients with DCLDs encountered at the First Affiliated Hospital of University of Science and Technology of China from Jan 1, 2017 to December 31, 2023.
Results: A total of 289 patients were identified with DCLDs; 212 females and 77 males, with a median age of 48 years (range, 18-81 years).

Introduction: Amyloidosis, a polymeric deposition disease classified according to protein subtype, may have varied pulmonary manifestations. Its anatomic-radiologic phenotypes include nodular, cystic, alveolar-septal, and tracheobronchial forms. Clinical presentation may range from asymptomatic parenchymal nodules to respiratory failure from diffuse parenchymal infiltration or diaphragmatic deposition.

Methods: A retrospective, population-based cohort of adults with incident ASS residing in Olmsted County, Minnesota, in 1998-2019, was assembled.
Introduction: Acute exacerbation of interstitial lung disease (AE-ILD) often results in death and poses significant challenges in clinical management. While corticosteroids are frequently employed, the optimal regimen and their clinical efficacy remain uncertain. To address this knowledge gap, we undertook a systematic review to evaluate the impact of steroid therapy on clinical outcomes in patients experiencing AE-ILD.
View Article and Find Full Text PDFAspiration-related syndromes comprise a broad spectrum of diseases affecting the airways and lung parenchyma resulting from inadvertent entry of oropharyngeal or gastric contents into the respiratory tract. The diagnosis can be challenging given lack of self-reported symptoms and unwitnessed or silent aspiration events. Aspiration is a common finding in healthy individuals suggesting that host defenses play a critical role in the pathophysiology.

We aimed to assess for variants of honeycombing associated with a more favorable prognosis.
Methods: A computer-assisted search was conducted to identify patients encountered at Mayo Clinic from 1998 to 2022 who had undergone chest CT that manifested exuberant honeycombing.
A 62-year-old woman came to our hospital with worsening cough and dyspnea over the preceding week, during which time she had been treated with azithromycin and prednisone for suspected pneumonia. She had no fever, chills, or sweats, but her cough had become productive of clear to blood-tinged phlegm during the interval. Medical history was significant for insulin-dependent diabetes mellitus and OSA.

In particular, patients without clinically evident muscle involvement pose a significant diagnostic challenge.
Methods: A computer-assisted search was conducted to identify patients with amyopathic interstitial lung disease associated with the presence of myositis-specific autoantibodies.
Background: Chronic lymphocytic leukemia (CLL) is the most common type of leukemia in Western countries. Although various patterns of lung involvement with CLL have been reported, data on clinicoradiologic presentation are sparse.
Methods: A computer-assisted search was conducted to identify patients encountered at Mayo Clinic from 1998 to 2022 and had leukemic pulmonary infiltrates (LPI) with CLL demonstrated on lung biopsy.

Histopathologic criteria of usual interstitial pneumonia (UIP)/idiopathic pulmonary fibrosis (IPF) were defined over the years and endorsed by leading organizations decades after Dr. Averill A. Liebow first coined the term UIP in the 1960s as a distinct pathologic pattern of fibrotic interstitial lung disease.
View Article and Find Full Text PDFCombined pulmonary fibrosis and emphysema (CPFE) syndrome refers to co-occurrence of two disease processes in the lung that can be difficult to diagnose but is associated with high morbidity and mortality burden. Diagnosis of CPFE is challenging because the two diseases can counterbalance respective impairments resulting in deceivingly normal-appearing chest radiography and spirometry in a dyspneic patient. Although an international committee published the terminology and definitions of CPFE in 2022, consensus on exact diagnostic criteria and optimal management strategy is yet to be determined.

The patient underwent total right hip arthroplasty in an outside hospital because of osteoarthritis; there was no history of trauma. After 48 h, she experienced dyspnea with severe hypoxemia.

There is a lack of data on long-term outcomes among adults with LCH. We conducted a retrospective record review of 219 adults (aged ≥18 years) with LCH.
View Article and Find Full Text PDFDiffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare, but increasingly recognized entity that primarily affects middle-aged and elderly women. It is characterized by abnormal proliferation of pulmonary neuroendocrine cells (PNECs) and is considered a preinvasive lesion for carcinoid tumorlets/tumors. Sometimes, DIPNECH is accompanied by constrictive bronchiolitis which usually manifests as chronic cough and/or dyspnea, along with airflow limitation on spirometry.

Traditionally, biological staging systems are used to stratify disease severity. Reduced aerobic capacity has recently been described as useful in identifying higher risk of cardiovascular events and death.

This study aimed to better characterize the presenting features and relevant aspects in optimizing the diagnosis and treatment of mediastinal paragangliomas.
Methods: A computer-assisted search of electronic health records was performed to identify adult patients (≥18 years) who underwent evaluation for a primary mediastinal paraganglioma at Mayo Clinic between January 2000 and April 2022.
