[Human trichinosis. A case simulating polymyositis]. / Triquinosis humana. Un caso que simula polimiositis.

The human trichinosis is a cosmopolitan rare zoonosis in Mexico. It presents clinically, with an infectious toxic pattern. Typical symptomatology includes: fever, diarrhea, facial edema and myalgias, which can resemble other illnesses like typhoid fever, angioneurotic edema, septicemia, rheumatic disease-like vasculitis and dermato-polymyositis. The treatment is based on the use of antiparasites. In this paper a trichinosis case is described in a woman, 29 years old who lives in the metropolitan area, with a clinical pattern that suggest polymyositis. The diagnosis was confirmed through a muscle biopsy. The treatment was albendazole and prednisone with successful results.

[Wegener's granulomatosis: state of carrier of Staphylococcus aureus and combined therapy]. / Granulomatosis de Wegener estado de portador de Staphylococcus aureus y terapéutica combinada.

A series of five cases with Wegener's granulomatosis (WG) is presented: two women and three men with an average age of 37 years old, with an average time of evolution of the disease of 5 years and systemic clinical presentation (respiratory, renal and ocular affection); the ANCA were positive; three of them were carriers of Staphylococcus aureus. All the patients received combined therapy composed by trimethoprim-sulfamethoxazole-cyclophosphamide (TMS-CFM) during approximately 29 months of follow- up, except for a pregnant patient. The patients showed a satisfactory clinical evolution with improvement of the manifestations of the disease. We suggest that, due to its benefits, the combination of TMS-CFM can be useful as a therapeutic alternative in WG.
