ABSTRACT
Leprosy is an ancient infectious disease caused by Mycobacterium leprae. According to comparative genomics studies, this disease originated in Eastern Africa or the Near East and spread with successive human migrations. The Europeans and North Africans introduced leprosy into West Africa and the Americas within the past 500 years. In Brazil, this disease arrived with the colonizers who disembarked at the first colonies, Rio de Janeiro, Salvador and Recife, at the end of the sixteenth century, after which it was spread to the other states. In 1854, the first leprosy cases were identified in State of Amazonas in the north of Brazil. The increasing number of leprosy cases and the need for treatment and disease control led to the creation of places to isolate patients, known as leprosaria. One of them, Colonia Antônio Aleixo was built in Amazonas in 1956 according to the most advanced recommendations for isolation at that time and was deactivated in 1979. The history of the Alfredo da Matta Center (AMC), which was the first leprosy dispensary created in 1955, parallels the history of leprosy in the state. Over the years, the AMC has become one of the best training centers for leprosy, general dermatology and sexually transmitted diseases in Brazil. In addition to being responsible for leprosy control programs in the state, the AMC has carried out training programs on leprosy diagnosis and treatment for health professionals in Manaus and other municipalities of the state, aiming to increase the coverage of leprosy control activities. This paper provides a historical overview of leprosy in State of Amazonas, which is an endemic state in Brazil.

Leprosy, an infectious disease caused by Mycobacterium leprae, affects mostly the skin and peripheral nerves. The polymethylmethacrylate has been used as bone cement, knee and intraocular implants as a bioexpansor, filling the area where it is applied. We describe the case of a Brazilian male with tuberculoid leprosy who developed muscular wasting between the metacarpals of both hands. Ten years after leprosy treatment, he was submitted to five applications of 10% polymethylmethacrylate. The treatment was successful, improving the appearance of his hands leading to a positive impact on the patient's life.

BACKGROUND: Although awareness of the relevance of leprosy and human immunodeficiency virus (HIV) coinfection is increasing worldwide, several aspects of this co-occurrence are not fully understood. METHODS: We describe clinical, pathological, immunological, and therapeutic long-term follow-up of a cohort of 25 individuals with leprosy and HIV infection from Manaus, Amazonas. RESULTS: Careful description of our cohort indicates a higher prevalence of leprosy in an HIV-positive population than that in the general population. We also observed upgrading shifting of leprosy clinical forms after initiation of highly active antiretroviral therapy and multidrug therapy and an impact of HIV infection on leprosy granuloma formation, among other features. CONCLUSION: Taken together, these new insights allow the proposition of a classification system that includes (1) leprosy and HIV true coinfection, (2) opportunistic leprosy disease, and (3) leprosy related to highly active antiretroviral therapy.
