RESUMO
The authors present a case of a probable Pott disease from central/southern Mexico, dated 300 BC to 500 AD. This case highlights the importance of iconotopsy/iconodiagnosis for a better description of the natural history of diseases, especially as a complement to morphological analyses of human remains (paleopathology) and laboratory exams (DNA or immunology testing).

BACKGROUND: Mycobacterium leprae infection has recently been detected in wild armadillos in Brazil. Leprosy is still endemic in Brazil and although its transmission is mostly by person-to-person contact, many cases report no history of previously known leprosy contact. It has been suggested that other sources of M. leprae may contribute to the transmission of leprosy in some areas. AIM: Our objective was to investigate whether contact with armadillos is associated with leprosy. METHODS: A case-control study was carried out in Brazil. Data was collected from 506 leprosy patients and 594 controls on exposure to armadillos and age, sex, place of birth and living conditions. Univariate analysis and unconditional logistic regression were conducted to investigate whether leprosy was associated with exposure to armadillos. RESULTS: Direct armadillo exposure was reported by 68% of leprosy cases and by 48% of controls (P < 0.001) roughly doubling the risk of leprosy, with odds ratio (OR) 2.0, 95% confidence interval (CI) [1.36-2.99]. CONCLUSION: The results of this study suggest that direct exposure to armadillos is a risk factor for leprosy in Brazil.

This randomized, single blind clinical trial was performed to compare the efficacy and toxicity of BP88 Sodium Stibogluconate (SS) to Glucantime(R) (N-methyl-glucamine), (GL). Sixty-three patients were randomly assigned to one of two groups: 32 patients were treated with GL and 3l patients were treated with SS. Both groups received 15mg Sb+5/kg/day for 20 days. Toxicity was evaluated through EKG, urea, creatinine, AST, ALT, alkaline phosphatase, amylase, and lipase, assessed before treatment, on day 10 and day 20 of treatment and 90 days after treatment. In the group treated with GL, 81% (26/32) of patients were cured compared to 77% (24/31) in the SS group. Five (16%) patients relapsed in the GL group compared to 6 (19%) in the SS group. One patient in each group did not respond to treatment. AST, ALT, amylase, and lipase were more elevated in the SS group (p < 0.05). In conclusion, the efficacy of both treatments was similar although there was more toxicity in the ES group.

We describe two patients who underwent cardiac transplantation for chronic cardiomyopathy of Chagas' disease, and in whom the disease was reactivated with the development of cutaneous lesions. In both cases, the skin lesions regressed completely after 2 months of therapy with allopurinol.
