RESUMEN
Purpose: To evaluate the effectiveness of treatments for ocular toxoplasmosis (OT).Methods: A review of charts was conducted from patients who experienced an active episode of OT treated at the Federal University of São Paulo and associated sites. OT charts were reviewed to determine treatment effectiveness based on clinical judgment, taking clinical course and outcome into consideration in addition to change in best-corrected visual acuity. Treatment emergent adverse events (TEAEs) were used to assess safety.Results: Overall, 451/1200 patient charts met the inclusion criteria. The most commonly prescribed treatment was trimethoprim + sulfamethoxazole (52.3%) followed by pyrimethamine + sulfadiazine (28%). Treatment was successful in 96.9% of patients. Irrespective of the treatment, active lesions were resolved in 63.9% of patients within 6 weeks. Vision improved in 56.3% of patients. The incidence of TEAEs was low (10%).Conclusions: All treatments were effective for active episodes of OT, with few side effects.

Toxoplasma gondii infection may be attributed to the ingestion of pork meat and contaminated water. In southern Brazil, the prevalence of blindness caused by T. gondii is the highest in the world. Our purpose is to determine the frequency of T. gondii DNA in commercial fresh sausage and cured salami samples from Rio Grande do Sul state, south of Brazil. A total of 118 samples (sausage and salami) from 8 different producers were collected and DNA was extracted. Real-time polymerase chain reaction (qPCR) technique was performed to detect T. gondii DNA using B1 marker. The frequency of T. gondii DNA among the total number of samples (sausage and salami) was 39% (46/118). Among these, a higher frequency of positivity was observed in the sausage samples (47.5%) when compared with the salami samples (17%). However, the mean parasite concentration was significantly higher in the salami samples. The prevalence of T. gondii DNA in fresh sausage and cured salami may indicate that infected pigs may be an important source of infections and a public health hazard to be considered.
