Panniculitis: another clinical expression of gout.

Gouty panniculitis is an unusual clinical manifestation of gout, characterized by the deposition of monosodium urate crystals in the lobular hypodermis. Its pathogenesis is poorly understood but is associated with hyperuricemia, and the clinical presence of indurate subcutaneous plaques, which may precede or appear subsequently to the articular clinical expression of tophaceous gout. The aim of this report is to describe the clinical characteristics and potential risk factors for the development of lobular panniculitis secondary to chronic tophaceous gout.

Trypanosoma cruzi, causative agent of Chagas disease, affects not only cardiac and intestinal structures but also neurological structures. A high prevalence of T. cruzi infection occurs in Colombia, prompting the present study.

Trypanosoma cruzi-associated cerebrovascular disease: a case-control study in Eastern Colombia.

Trypanosoma cruzi infection is a common cause of cardiopathy in South America leading it eventually to an established stroke; however, the association between T. cruzi infection itself and cerebrovascular disease is still unknown. We did a case-control study at Eastern Colombia and found that T.
