A 30-year-old man presented to the emergency department with rapidly worsening swelling of the lips (see accompanying figure) that began three hours earlier. He had a history of a developmental disability and hypertension treated with lisinopril (Zestril) for two years. He had no previous episodes of swelling. Physical examination revealed localized swelling of the upper and lower lips, but no ...

A 70 year old man, a non-smoker, presented with a painful swelling over the right sternoclavicular joint and low grade continuous fever for a period of two months. The patient had been empirically started on antituberculous therapy on the suspicion of tuberculous osteomyelitis, but his fever and swelling persisted. On clinical examination, a hard and tender swelling was present over the right s...

The swelling of percolation clusters as models for gelling branched polymers is analyzed by using a simple mean-field approach (for all dimensions) and a Monte-Carlo simulation (for d = 3, bond fluctuation method). The numerical swelling exponent ~' = 0.443 + 0.008 shows a significant deviation from the lattice animals solution ~' = 0.5, which is caused by the difference between quenched and an...
