RESUMO
OBJECTIVE: To explore the effect of the school feeding program purchase criteria on the quantity, variety and origin of food products acquired for school meals in a municipality in Brazil. METHOD: Analysis of purchase lists for two years prior and two years after implementation of the purchase criteria (2010). The origin (family farms (FF)/other providers (OP)) and nutritional characteristics (recommended/controlled) of food products were studied, registering annual varieties (n) and daily quantities (kg/day); contrast of proportions was applied. RESULTS: The acquisition of recommended products increased, and the quantity of controlled products decreased (p = 0.005). Purchase of legumes and vegetables (p < 0.05) increased and high sugar foods decreased (p = 0.02). The majority of food products in 2010 and 2011 were acquired from OP (64% and 61%), although FF provided the greatest proportion of legumes and vegetables. Ten new varieties of recommended products were incorporated, 9 of which were acquired from FF. CONCLUSION: The criteria of direct purchase from family farms resulted in an increase in the variety and quantity of healthy foods in the schools in the municipality.

Organ transplantation (TX) is a novel transmission modality of Chagas disease. The results of molecular diagnosis and characterization of Trypanosoma cruzi acute infection in naïve TX recipients transplanted with organs from infected deceased donors are reported. Peripheral blood and cerebrospinal fluid samples from the TX recipients of organs from infected donors were prospectively and sequentially studied for detection of T. cruzi by means of kinetoplastid DNA polymerase chain reaction (kDNA-PCR). In positive blood samples, a PCR algorithm for identification of T. cruzi Discrete Typing Units (DTUs) and quantitative real-time PCR (qPCR) to quantify parasitic loads were performed. Minicircle signatures of T. cruzi infecting populations were also analyzed using restriction fragment length polymorphism (RFLP)-PCR. Eight seronegative TX recipients from four infected donors were studied. In five, the infection was detected at 68.4 days post-TX (36-98 days). In one case, it was transmitted to two of three TX recipients. The comparison of the minicircle signatures revealed nearly identical RFLP-PCR profiles, confirming a common source of infection. The five cases were infected by DTU TcV. This report reveals the relevance of systematic monitoring of TX recipients using PCR strategies in order to provide an early diagnosis allowing timely anti-trypanosomal treatment.

Parotid gland metastases from malignant tumors are extremely rare. A 61-year-old woman was diagnosed with an early breast cancer with no expression of oestrogen and progesterone receptors. Five years later the patient presented a tumour in parotid gland. After total parotidectomy, microscopic analysis of the gland demonstrated an invasive duct carcinoma (IDC) with positive expression of oestrogen receptor. The patient was treated with chemotherapy followed by complementary local radiotherapy. Diagnosis of a metastasic tumour in parotid gland poses a challenge. In our case an immunohistochemical study of oestrogen receptor was fundamental to establish a diagnosis.
