Abstract
Paracoccidioidomycosis (PCM), initially reported in 1908 in the city of São Paulo, Brazil, by Adolpho Lutz, is primarily a systemic and neglected tropical mycosis that may affect individuals with certain risk factors around Latin America, especially Brazil. Paracoccidioides brasiliensis sensu stricto, a classical thermodimorphic fungus associated with PCM, was long considered to represent a monotypic taxon. However, advances in molecular taxonomy revealed several cryptic species, including Paracoccidioides americana, P. restrepiensis, P. venezuelensis, and P. lutzii, that show a preference for skin and mucous membranes, lymph nodes, and respiratory organs but can also affect many other organs. The classical diagnosis of PCM benefits from direct microscopy culture-based, biochemical, and immunological assays in a general microbiology laboratory practice providing a generic identification of the agents. However, molecular assays should be employed to identify Paracoccidioides isolates to the species level, data that would be complemented by epidemiological investigations. From a clinical perspective, all probable and confirmed cases should be treated. The choice of treatment and its duration must be considered, along with the affected organs, process severity, history of previous treatment failure, possibility of administering oral medication, associated diseases, pregnancy, and patient compliance with the proposed treatment regimen. Nevertheless, even after appropriate treatment, there may be relapses, which generally occur 5 years after the apparent cure following treatment, and also, the mycosis may be confused with other diseases. This review provides a comprehensive and critical overview of the immunopathology, laboratory diagnosis, clinical aspects, and current treatment of PCM, highlighting current issues in the identification, treatment, and patient follow-up in light of recent Paracoccidioides species taxonomic developments.

Abstract
INTRODUCTION The study aimed to show the situation of paracoccidioidomycosis in the state of Maranhão, Brazil. METHODS This study is a descriptive case series developed in two stages. First, a survey of cases originating from the state of Maranhão at the Instituto de Doenças Tropicais Natan Portela, Piauí (IDTNP) from 1997 to 2007, and second, the clinical description of 29 cases diagnosed in the Centro de Referências em Doenças Infecciosas e Parasitárias, Maranhão (CREDIP) from 2004 to 2010. RESULTS Two hundred and sixteen cases have been cataloged at the IDTNP. West, east, and central regions of the state of Maranhão recorded 90.3% of cases proving to be important areas for study. The western region, with a prevalence of 10.8/100,000 inhabitants, has a significantly higher proportion of cases than the northern, southern, and eastern regions (p < 0.05). The occurrence was higher in men with 89.3% of cases, and the male-to-female ratio was 8.4:1. The majority of patients were older than 20 years, lived in rural areas, and had farming or soil management as main occupation (73.8%). At CREDIP, 29 cases were diagnosed, of which 26 (89.6%) had multifocal manifestations. Mucous tissues were involved more (75.8%) frequently, followed by lymph nodes, skin, and lungs with 65.5%, 39% and 37.9 %, respectively. The diagnosis was made by combining direct examination, culture, and histopathology. CONCLUSIONS The study shows the geographical distribution and the epidemiological and clinical aspects of paracoccidioidomycosis, revealing the significance of the disease to the state of Maranhão.

Abstract
Paracoccidioidomycosis (South American blastomycosis) is an uncommon, progressive systemic mycosis, potentially fatal if untreated. It is virtually restricted to persons spending time in Latin America. Reports of oral lesions are extremely rare in the English-language literature. Three adults with oral lesions as the first sign of paracoccidioidomycosis are described; this appears to be the largest series in the dental literature. The oral lesions had a characteristic appearance with a granular purpuric surface. The upper gingiva was a typical site, but lesions were also seen in the palate, tongue, and buccal mucosa. Two of the patients proved to have detectable pulmonary involvement. Long-term systemic ketoconazole therapy produced resolution of oral lesions in all cases.

Abstract
The effect of Ketoconazole (KTZ) on the hamster experimental intratesticular paracoccidioidomycosis was studied employing different treatment schedules. KTZ long course treatment beginning at an early stage of the infection was effective in preventing fungal proliferation, dissemination to lymph nodes, spleen and kidneys, and in maintaining low levels of humoral and cellular specific immune responses. KTZ short course treatment starting at an advanced stage of disease resulted in a more severe histopathological picture without significant changes in the immunological profile. The drug prolonged the life span of hamsters infected with Paracoccidioides brasiliensis, but did not prevent mortality. Toxic necrosis of the bone marrow occurred in normal animals receiving 120 mg/kg/day of KTZ but with lower doses no morphologic alterations were observed in heart, lungs, kidneys, adrenals, spleen, liver, intestine or bone marrow.

Abstract
Foram, tratados 12 doentes atendidos na Disciplina de Moléstias Infecciosas e Parasitárias da Faculdade de Medicina de Botucatu com diagnóstico etiológico de paracoccidioidomicose que apresentavam lesões orgânicas múltiplas e evolução prolongada. O tratamento foi realizado por 18 meses, com o ketoconazol, pela via oral, nas doses diárias de 400 mg no primeiro mês e de 200 mg nos meses seguintes. Todos os doentes foram acompanhados durante o tratamento e, em média 4 meses e meio após o mesmo, clínica, radiológica e sorologicamente pelas reações de imunofluorescência indireta, precipitinas e imunodifusão em gel. A competência imunitária foi avaliada em todos os doentes antes do tratamento e repetida em quatro, no final do mesmo. Os resultados mostraram que houve recaída em 5 doentes. A droga foi bem tolerada e a imunodifusão em gel e a hemossedimentação foram as provas que mostraram maior paralelismo com a evolução clínica.

Abstract
The results of ketoconazole therapy in 38 patients with active paracoccidioidomycosis are described. Treatment consisted of a 200 mg tablet a day for 6 months. Evaluation was accomplished by means of a scoring system and the results were as follows: none of the patients worsened during therapy, one was found to be unchanged, five had minor improvement, 330 had major improvement, and there was complete resolution of the pretherapy conditions in 13. These findings plus the lack of toxicity of the drug and the facility for oral administration, make of ketoconazole a first line drug for the treatment of paracoccidioidomycosis.
