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...

Volume 89, Number 5 www.aafp.org/afp American Family Physician 381 An 89-year-old man had joint pain, swelling, and the inability to flex his fifth finger for several years. The swelling had appeared gradually after episodes of acute pain in that finger. He had chronic kidney disease (creatinine level of 5.3 mg per dL [468 μmol per L]) and poorly controlled diabetes mellitus (fasting glucose le...

Hydrogels are crosslinked macromolecular networks saturated by water solutions and they are an example of a swelling material. The behaviour of swelling materials can be described by a multi-component mixture model [1], which takes into account four components of the material: solid, liquid, cation and anion, together with their interactions. Hydrogels are very biocompatible because their chara...
