Paracoccidioidomycosis in children in the state of Rio de Janeiro (Brazil): Geographic distribution and the study of a "reservarea"

Revista do Instituto de Medicina Tropical de São Paulo (1998)

Adrelírio José Rios Gonçalves A. T. Londero Glaura Martha Florim Terra Ronaldo Rozenbaum Thalita Fernandes de Abreu

Thirty six cases of acute disseminated paracoccidioidomycosis in 3 to 12 year-old children, natives of the state of Rio de Janeiro, were seen in the period 1981-1996. All patients were residents in the rural region of 15 counties, scattered on the Southwestern part of this state. The rural region of two neighboring counties, where 16 cases (44.4%) occurred, was visited. It exhibited the environmental conditions that are considered favorable to the survival of P. brasiliensis. The most important of these conditions, abundant watercourses and autochthonous forest, are distributed on well defined and limited areas, in which the dwellings are also localized. Probably, a careful epidemiological study of forthcoming cases of the disease in children may facilitate the search for the micro-niche of the fungus.

Coxiella burnetii, the agent of Q fever in Brazil: its hidden role in seronegative arthritis and the importance of molecular diagnosis based on the repetitive element IS1111 associated with the transposase gene

Memórias do Instituto Oswaldo Cruz (2012)

Tatiana Rozental Luis Filipe Mascarenhas Ronaldo Rozenbaum Raphael Gomes Grasiely Souza Mattos

Coxiella burnetii is the agent of Q fever , an emergent worldwide zoonosis of wide clinical spectrum. Although C. burnetii infection is typically associated with acute infection, atypical pneumonia and flu-like symptoms, endocarditis, osteoarticular manifestations and severe disease are possible, especially when the patient has a suppressed immune system; however, these severe complications are typically neglected. This study reports the sequencing of the repetitive element IS1111 of the transposase gene of C. burnetii from blood and bronchoalveolar lavage (BAL) samples from a patient with severe pneumonia following methotrexate therapy, resulting in the molecular diagnosis of Q fever in a patient who had been diagnosed with active seronegative polyarthritis two years earlier. To the best of our knowledge, this represents the first documented case of the isolation of C. burnetii DNA from a BAL sample.

Mycobacterium haemophilum: Emerging or Underdiagnosed in Brazil?

Emerging infectious diseases (2002)

Jorge Luiz Mello Sampaio Venâncio Avancini Ferreira Alves Sylvia Cardoso Leão Vanda Dolabela de Magalhães Marinês Dalla Valle Martino

To the Editor: Mycobacterium haemophilum was first described in 1978 by Sompolinsky et al. (1) as the cause of cutaneous infections in a patient with Hodgkin disease.Since then, fewer than 100 cases have been reported worldwide, mostly among immunocompromised patients (2), although M. haemophilum infection has also been described in immunocompetent patients as the cause of cervical, submandibular, and perihilar lymphadenopathy in children and of pulmonary nodules in an adult (3-5).Cases have been reported from United States, Australia, Canada, France, Israel, and the United Kingdom, but to date no reports have originated in South America.The most frequent clinical sign of M. haemophilum infection in adults is a skin or joint lesion.Less common sites for isolation of M. haemophilum include the respiratory tract, blood, bone marrow, bone, and central venous catheters (2,6).M. haemophilum is unique among Mycobacterium species owing to its special growth requirements: it grows best at 30°C and requires an iron supplement (hemin or ferric ammonium citrate).We report here the characterization of three strains of M. haemophilum isolated from patients living in three states in two distinct regions of Brazil, Rio de Janeiro and São Paulo (southeast region) and Bahia (northeast region).The first strain was detected in Rio de Janeiro in December 2000 from a blood culture of a 67-year-old man who had received a kidney transplant in 1988 at the age of 55 years and was undergoing immunosuppressive treatment with prednisolone and mycophenolate mofetil.

Clinical Epidemiological Study of 171 Cases of Cryptococcosis

Clinical Infectious Diseases (1994)

Ronaldo Rozenbaum Adrelírio José Rios Gonçalves

We retrospectively studied 171 patients with cryptococcosis who were divided into three groups according to their associated predisposing conditions (if any): group 1 comprised nonimmunosuppressed patients, group 2 comprised patients with AIDS, and group 3 comprised those patients with other conditions and/or who were users of immunosuppressive drugs. Analysis and correlation of the behavior of the mycosis among the three groups showed differences in the demographic data, clinical forms and manifestations of cryptococcosis, laboratory results, morbidity and mortality rates, and histopathologic aspects. Study of the clinical isolates of Cryptococcus neoformans from 83 patients with cryptococcosis showed that 75 were characterized as C. neoformans variety neoformans and eight as C. neoformans var. gattii. Comparison of the distribution of the gattii and neoformans varieties between the nonimmunosuppressed (group 1) and immunosuppressed (groups 2 and 3) patients showed a significant statistical difference (P < .01).
