We present four cases of patients admitted to an acute geriatric unit with a presumptive diagnosis of bronchiolitis obliterans organizing pneumonia between 2001 and 2005. Because of the difficulty of performing transbronchial biopsy in these patients, who showed a variety of clinical presentations, the suspected diagnosis was based on clinical and radiological findings and a favorable response to empirical corticosteroid treatment. The clinical and radiological features of this entity in the elderly, as well as the therapeutic options, are reviewed.

Bronchiolitis obliterans (BO) is a disease characterized by airway obstruction and fibrosis that can occur in all age groups. Bronchiolitis obliterans syndrome (BOS) is a clinical manifestation of BO in patients who have undergone lung transplantation or hematopoietic stem cell transplantation. Persistent inflammation and fibrosis of small airways make the disease irreversible, eventually leading to lung failure.

Objective: Bronchoscopy plays a critical role in the diagnosis and management of lung transplant recipients. We retrospectively evaluated the safety, complications, and efficacy of transbronchial biopsy (TBB) in detecting and grading early rejection.
Materials And Methods: We retrospectively assessed the complications associated with TBB and the adequacy of pathological diagnoses in patients who underwent lung transplantation at Koşuyolu Yüksek İhtisas Training and Research Hospital from December 1, 2016, to April 30, 2023.

Background: Bronchiolitis obliterans syndrome (BOS) is one of the most devastating outcomes of chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). This remains an area of unmet clinical need for optimal therapy for BOS patients partly due to the limited understanding of pathogenic mechanisms.
Methods: We collected blood samples from 22 patients with cGVHD and 11 patients without cGVHD following allo-HSCT.

Currently, the barrier to successful lung transplantation is ischemia and reperfusion injury, which can lead to the development of bronchiolitis obliterans. Paclitaxel and methotrexate are drugs known to inhibit cell proliferation and have anti-inflammatory effects, and the association of these drugs with cholesterol-rich nanoparticles has been shown to be beneficial in the treatment of other transplanted organs. Thirty-three male Sprague Dawley rats were divided into 3 groups: Basal group, no intervention; Control group, received only nanoparticles; Drug group, paclitaxel and methotrexate treatment.

After the cancellation of COVID-19 epidemic control measures in 2023, cases of pediatric bronchiolitis caused by Mycoplasma pneumoniae (MP) have been reported successively, with some children experiencing residual bronchiolitis obliterans (BO). Currently, the diagnosis of bronchiolitis Mycoplasma pneumoniae pneumonia (MPP) primarily relies on high-resolution computed tomography (HRCT). To establish a predictive model for bronchiolitis MPP, a retrospective analysis was conducted.
