Objective: To describe the epidemiological aspects of childhood tuberculosis (TB) in a Brazilian reference hospital. Methods: This was a retrospective study (1999-2008) of 473 subjects (0-14 year olds) with confirmed TB, or with clinical improvement by the fourth month of treatment under the unit's care, including the review of medical records, monitoring reports and notifications by the TB unit. Results: Among 473 TB cases included in the study, positive tuberculin skin test was observed in 52%, history of contact with a patient with pulmonary tuberculosis in 66%, mostly intra-household, and with the father/stepfather most commonly involved; and disseminated TB in 22%. The result of HIV testing was obtained in 265 (56%) cases, being positive in 45 (17%). The diagnosis of TB was confirmed in 31% of cases, most frequently in children older than 5 years, with negative tuberculin skin test, and in disseminated forms. Of the 65 cultures positive for TB performed in the study, drug sensitivity testing to anti-TB drugs was done in 30 (46%) clinical samples, among which 10 (33%) were resistant to one or more anti-TB drugs, and 2 (0.8%) were multi-drug-resistant. Among patients with confirmed pulmonary TB, 31% did not meet the criteria for starting anti-TB treatment according to the scores of the Ministry of Health (<= 25 points). Conclusion: The high proportion of drug-resistant TB and co-infection with HIV identified in this study highlight the necessity to carry out additional studies in order to evaluate the impact of TB control activities on childhood TB.

Peripheral blood smears of 1094 domestic cats were collected and tested by indirect immunofluorescence antibody assay for p27 antigen in cells to study the prevalence and risk factors for feline leukemia virus (FeLV) in the state of Rio de Janeiro. Sex, age, breed, outdoor access, neutering status, type of habitation (household, shelter, veterinary clinics and other places), number of household cats and clinical signs were registered on a form. Among the tested samples, 11.52% were positive. Risk factors for FeLV infection included outdoor access, age range between 1 and 5 years old, and cohabitation with numerous cats.

The occurrence of ochratoxin A (OTA) in wine from 2002 to 2008 harvest, traded in Rio de Janeiro State, was evaluated by analysing 43 national and 37 imported wines from Argentina (32) and Chile (5), adding up to 80 samples in total. OTA determination was performed using immunoaffinity columns and high-performance liquid chromatography. In 80 wine samples analysed, 25 (31.3%) were positive, presenting levels greater than 0.020 ng OTA mL(-1). It was not detected in imported wines. Within national wines, 58.1% of the samples were contaminated, with levels ranging from 0.020 to 0.050 ng mL(-1). The toxin was detected in 18 (69.2%) of 26 samples analysed of red table wine. Wines from 2008 harvest presented 84.6% of samples contaminated in 13 samples analysed. Despite the levels found in this study, they are below Brazilian tolerance limits. Nevertheless, the presence of OTA as found contributes to the human exposure to this toxin.

During 2008D2010, ticks were collected from road-killed wild animals within the Serra dos Orgaos National Park area in the state of Rio de Janeiro, Brazil. In total, 193 tick specimens were collected, including Amblyomma dubitatum Neumann and Amblyomma cajennense (F.) from four Hydrochoerus hydrochaeris (L.), Amblyomma calcaratum Neumann and A. cajennense from four Tamandua tetradactyla (L.), Amblyomma aureolatum (Pallas) and A. cajennense from five Cerdocyon thous L., Amblyomma longirostre (Koch) from one Sphiggurus villosus (Cuvier), Amblyomma varium Koch from three Bradypus variegatus Schinz, and A. cajennense from one Buteogallus meridionalis (Latham). Molecular analyses based on polymerase chain reaction targeting two rickettsial genes (gltA and ompA) on tick DNA extracts showed that 70.6% (12/17) of the A. dubitatum adult ticks, and all Amblyomma sp. nymphal pools collected from capybaras were shown to contain rickettsial DNA, which after DNA sequencing, revealed to be 100% identical to the recently identified Rickettsia sp. strain Pampulha from A. dubitatum ticks collected in the state of Minas Gerais, Brazil. Phylogenetic analysis with concatenated sequences (gltA-ompA) showed that our sequence from A. dubitatum ticks, referred to Rickettsia sp. strain Serra dos Orgaos, segregated under 99% bootstrap support in a same cluster with Old World rickettsiae, namely R. tamurae, R. monacensis, and Rickettsia sp. strain 774e. Because A. dubitatum is known to bite humans, the potential role of Rickettsia sp. strain Serra dos Orgaos as human pathogen must be taken into account, because both R. tamurae and R. monacencis have been reported infecting human beings.

This article explores the construction of publicly financed low-income housing complexes in Rio de Janeiro, Brazil, and Buenos Aires, Argentina, in the 1960s. These housing developments were possible thanks to the arrival of foreign economic and technical assistance from the Alliance for Progress. Urban scholars, politicians, diplomats and urbanists of the Americas sought to promote middle-class habits, mass consumption and moderate political behaviour, especially among the poor, by expanding access to homeownership and ‘decent’ living conditions for a burgeoning urban population. As a result, the history of low-income housing should be understood within broader transnational discourses and practices about the ‘modernization’ and ‘development’ of the urban poor.
