Acute bronchiolitis is a common disease of infants affecting the small airways. Rarely, acute bronchiolitis may occur in adolescents and adults. Here, we present four unrelated adolescent patients with severe clinical presentation and unique CT imaging with extensive tree-in-bud pattern, representing a rare clinical phenotype of acute diffuse panbronchiolitis. This characteristic disease pattern caused by inhalation injury from waterpipes, smoked tobacco, and cannabinoids must be differentiated from e-cigarette or vaping product-use-associated lung injury (EVALI). Visual diagnosis of CT and an early diagnostic procedure for detection and differentiation of inhaled hazards, including sample storage for future identification of novel noxious agents, are warranted.

Human Applications of the Anstadt Cup: Implications for Non-Blood-Contacting Biventricular Support.

Background: Direct mechanical ventricular actuation (DMVA) with the Anstadt cup is effective for non-blood-contacting biventricular support. Pneumatic regulation of a silicone device augments ventricular pump function. Vacuum attachment facilitates diastolic augmentation critical for biventricular support.

This study evaluates the efficacy of deep learning models in identifying infarct tissue on computed tomography perfusion (CTP) scans from patients with acute ischemic stroke due to large vessel occlusion, specifically addressing the potential influence of varying noise reduction techniques implemented by different vendors. We analyzed CTP scans from 60 patients who underwent mechanical thrombectomy achieving a modified thrombolysis in cerebral infarction (mTICI) score of 2c or 3, ensuring minimal changes in the infarct core between the initial CTP and follow-up MR imaging. Noise reduction techniques, including principal component analysis (PCA), wavelet, non-local means (NLM), and a no denoising approach, were employed to create hemodynamic parameter maps.

Objective: To evaluate the relationship between infarct pattern, inferred stroke mechanism and risk of recurrence in patients with ischaemic stroke. The question is clinically relevant to optimise secondary stroke prevention investigations and treatment.
Design: We conducted a retrospective analysis of the dabigatran treatment of acute stroke II (DATAS II) trial (ClinicalTrials.
Impact of corticosteroids on improving lung compliance in a patient with pulmonary microscopic polyangiitis.

Microscopic polyangiitis (MPA) is a small-vessel vasculitis characterised by systemic infiltration, with a primary focus on the renal and pulmonary systems. One of its more lethal pulmonary manifestations is diffuse alveolar haemorrhage (DAH), although the spectrum of lung pathology in MPA is vast and calls for immediate immunosuppressive therapy. Our case looks at an older woman initially presenting with MPA-induced rapid progressive glomerulonephritis.

Waterhouse-Friderichsen Syndrome (WFS) is a rare but life-threatening condition characterized by massive adrenal hemorrhage. WFS represents one of the features of the Overwhelming Post-Splenectomy Infection, which occurs any time after spleen removal and is recognized as the most serious complication in asplenic patients. We report a fatal case of WFS resulting from Streptococcus pneumoniae infection in a vaccinated and splenectomized patient.
