Extensive Subcutaneous Emphysema Post-traumatic Tube Thoracostomy.

Bronchocutaneous fistula (BCF) is a pathologic communication between the bronchus and the subcutaneous tissue. Its diagnosis is made mainly by chest imaging, and bronchoscopy can help in accurately localizing the fistula. Treatment options include conservative and non-conservative approaches.

Acute Respiratory Distress Syndrome Secondary to Radiotherapy for Breast Cancer: A Case Report.

BACKGROUND Radiotherapy is often used as an adjuvant therapy in breast cancer following surgical resection of the primary malignant tumor. It has multiple respiratory side effects, but acute respiratory distress syndrome (ARDS) is a rare complication. We describe here the case of a woman with breast cancer who developed ARDS 1 week after her final radiotherapy session.

Two time scales for self and collective diffusion near the critical point in a simple patchy model for proteins with floating bonds.

Using dynamic Monte Carlo and Brownian dynamics, we investigate a floating bond model in which particles can bind through mobile bonds. The maximum number of bonds (here fixed to 4) can be tuned by appropriately choosing the repulsive, nonadditive interactions among bonds and particles. We compute the static and dynamic structure factor (intermediate scattering function) in the vicinity of the gas-liquid critical point.

Onset of anomalous diffusion in colloids confined to quasimonolayers.

It has been recently shown that a colloidal monolayer, e.g., formed at a fluid interface or by means of a suitable confining potential, exhibits anomalous collective diffusion.

A dynamic DFT approach to generalized diffusion equations in a system with long-ranged and hydrodynamic interactions.

We build on an existing approximation scheme to the Smoluchowski equation in order to derive a dynamic density functional theory (DDFT) including two-body hydrodynamic interactions. A generalized diffusion equation and a wavenumber-dependent diffusion coefficient D(k) are derived by linearization in the density fluctuations. The result is applied to a colloidal monolayer at a fluid interface, having bulk-like hydrodynamic interactions and/or interacting via long-ranged capillary forces.
