Case 276: Pulmonary Veno-Occlusive Disease and Pulmonary Capillary Hemangiomatosis Disease.

HistoryA 34-year-old man presented to the emergency department of our hospital for progressive shortness of breath and worsening productive cough of 2 weeks duration. He reported a 10-kg weight loss over 4 months but denied experiencing fever, chills, night sweats, or gastrointestinal, musculoskeletal, or neurologic symptoms. His medical history was unremarkable.

Variability of CT Airways Measurements in COPD Patients Between Morning and Afternoon: Comparisons to Variability of Spirometric Measurements.

Rationale And Objectives: Computed tomography (CT) airways measurements can be used as surrogates to spirometric measurements for assessing bronchodilation in a particular patient with chronic obstructive pulmonary disease. Although spirometric measurements show variations within the opening hours of a hospital department, we aimed to compare the variability of CT airways measurements between morning and afternoon in patients with chronic obstructive pulmonary disease to that of spirometric measurements.

Materials And Methods: Twenty patients had pulmonary function tests and CT around 8 am and 4 pm.

Effect of total lung capacity, gender and height on CT airway measurements.

Objective: Testing the hypothesis that CT airway measurements could be influenced by total lung capacity (TLC), gender and height in normal individuals.

Methods: In this ethics committee-approved prospective trial, 87 healthy never-smoking volunteers who provided written informed consent were included. From a helical CT scan of the chest, the wall thickness (WT) and the lumen area were twice measured in the third- and fourth-generation airways by three readers using a dedicated software.
