Abstract Objective: to describe the filling process of the Child Health Record (CHR) in health care services. Methods: descriptive study held in Belo Horizonte, Minas Gerais, Brazil; an interview was conducted with parents/guardians of children aged 3-5 years old; 21 essential items to child monitoring were observed in the CHR during the 2014 Multi-vaccination Day; fields that should be filled in maternity wards, Primary Health Care (PHC), and other services were assessed separately. Results: 367 children (96.1%) were included; 44.5% of CHR presented ≥60% of completeness; among the items that should be recorded in maternity wards, birth weight showed the highest proportion of completeness (64.5%); for those that should be filled in PHC/other services, records of vaccines (94.0%) presented the highest completeness; there was more filling in maternity wards than in PHC and other services (p<0.001). Conclusion: a low proportion of filling was observed, especially in PHC and other services.

Drug resistance is a global threat and one of the main contributing factors to tuberculosis (TB) outbreaks. The goal of this study was to analyse the molecular profile of multidrug-resistant TB (MDR-TB) in the state of Santa Catarina in southern Brazil. Fifty-three MDR Mycobacterium tuberculosis clinical isolates were analysed by spoligotyping and a partial region of the rpoB gene, which is associated with rifampicin resistance (RMP-R), was sequenced. Some isolates were also distinguished by their mycobacterial interspersed repetitive units (MIRU). S531L was the most prevalent mutation found within rpoB in RMP-R isolates (58.5%), followed by S531W (20.8%). Only two MDR isolates showed no mutations within rpoB. Isolates of the Latin American Mediterranean (LAM) family were the most prevalent (45.3%) found by spoligotyping, followed by Haarlem (9.4%) and T (7.5%) families. SIT106 was found in 26.4% of isolates and all SIT106 isolates typed by MIRU-12 (5 out of 14) belong to MIT251. There was a high correlation between the S531W mutation and the LAM family mainly because all SIT2263 (LAM9) isolates carry this mutation. Among isolates with the S531W mutation in rpoB MIRU demonstrates a cluster formed by four isolates (SIT2263 and MIT163) and very similar profiles were observed between eight of the nine isolates. Better characterisation of TB isolates may lead to new ways in which to control and treat TB in this region of Brazil.

The identification of mycobacteria is essential because tuberculosis (TB) and mycobacteriosis are clinically indistinguishable and require different therapeutic regimens. The traditional phenotypic method is time consuming and may last up to 60 days. Indeed, rapid, affordable, specific and easy-to-perform identification methods are needed. We have previously described a polymerase chain reaction-based method called a mycobacteria mobility shift assay (MMSA) that was designed for Mycobacterium tuberculosis complex (MTC) and nontuberculous mycobacteria (NTM) species identification. The aim of this study was to assess the MMSA for the identification of MTC and NTM clinical isolates and to compare its performance with that of the PRA-hsp65 method. A total of 204 clinical isolates (102 NTM and 102 MTC) were identified by the MMSA and PRA-hsp65. For isolates for which these methods gave discordant results, definitive species identification was obtained by sequencing fragments of the 16S rRNA and hsp65 genes. Both methods correctly identified all MTC isolates. Among the NTM isolates, the MMSA alone assigned 94 (92.2%) to a complex or species, whereas the PRA-hsp65 method assigned 100% to a species. A 91.5% agreement was observed for the 94 NTM isolates identified by both methods. The MMSA provided correct identification for 96.8% of the NTM isolates compared with 94.7% for PRA-hsp65. The MMSA is a suitable auxiliary method for routine use for the rapid identification of mycobacteria.

OBJETIVO: Identificar micobactérias não tuberculosas (MNT) isoladas de sítios estéreis em pacientes internados no Hospital Universitário Clementino Fraga Filho, Rio de Janeiro (RJ) entre 2001 e 2006. MÉTODOS: Durante o período do estudo, 34 isolados de MNT de sítios estéreis de 14 pacientes, a maioria HIV positivos, foram submetidos a identificação fenotípica e hsp65 PCR-restriction enzyme analysis (PRA, análise por enzimas de restrição por PCR do gene hsp65). RESULTADOS: A maioria dos isolados foi identificada como Mycobacterium avium, seguida por M. monacense, M. kansasii e M. abscessus em menores proporções. CONCLUSÕES: A combinação de PRA, um método relativamente simples e de baixo custo, com algumas características fenotípicas pode fornecer a identificação correta de MNT na rotina de laboratórios clínicos.

OBJECTIVE: To identify nontuberculous mycobacteria (NTM) isolated from sterile sites in patients hospitalized between 2001 and 2006 at the Clementino Fraga Filho University Hospital, located in the city of Rio de Janeiro, Brazil. METHODS: During the study period, 34 NTM isolates from sterile sites of 14 patients, most of whom were HIV-positive, were submitted to phenotypic identification and hsp65 PCR-restriction enzyme analysis (PRA). RESULTS: Most isolates were identified as Mycobacterium avium, followed by M. monacense, M. kansasii, and M. abscessus. CONCLUSIONS: The combination of PRA, a relatively simple and inexpensive method, with the evaluation of a few phenotypic characteristics can allow NTM to be accurately identified in the routine of clinical laboratories.

INTRODUÇÃO: As taxas de resistência aos fármacos constituem um dos pilares da avaliação dos programas de controle da tuberculose. A demora na obtenção dos resultados, conseqüência da metodologia convencional utilizada, faz com que haja a necessidade de avaliação de novos testes, mais rápidos e menos onerosos. OBJETIVO: Comparar técnicas fenotípicas rápidas para determinação do perfil de susceptibilidade de M. tuberculosis, utilizando indicadores de viabilidade celular, com o teste das proporções em Löwenstein-Jensen, padrão-ouro. MÉTODO: Foram utilizadas 166 cepas de M. tuberculosis com o perfil de susceptibilidade conhecido. A concentração mínima inibitória de cada fármaco foi determinada, em microplaca, utilizando-se meio líquido e os indicadores de oxi-redução, Alamar Blue® e brometo de tetrazolium. O ponto de corte entre a cepa sensível e a resistente foi estabelecido como concentração mínima inibitória maior ou igual a 0,2 mg /mL para isoniazida e 1,0 mg /mL para rifampicina. RESULTADOS: Houve concordância total entre os dois métodos de determinação da concentração mínima inibitória. Comparando os resultados dos testes com o padrão-ouro, obteve-se uma concordância de 95%, para isoniazida e rifampicina. O tempo para obtenção dos resultados foi de 7 dias, contrastando com os 28 dias pelo método convencional. CONCLUSÃO: Os testes para determinação da concentração mínima inibitória, em meio líquido, utilizando indicadores de oxi-redução, são rápidos e podem se utilizados como alternativa rápida na determinação de susceptibilidade de cepas de M. tuberculosis.

BACKGROUND: Knowledge of the rates of drug resistance is one of the pillars of tuberculosis control program evaluation. Data from low-resource countries are scarce and results are delayed due to the techniques employed. There is therefore an urgent need for evaluation of faster and less onerous testing methods. OBJECTIVE: To compare the performance of rapid colorimetric assays for phenotyping that employ oxidation-reduction indicators to determine the susceptibility profile of Mycobacterium tuberculosis with the gold-standard proportion method on Lowenstein-Jensen Medium. METHOD: We analyzed 166 M. tuberculosis strains of known susceptibility. Minimal inhibition concentrations for isoniazid and rifampicin were determined in microplates, using a liquid medium and Alamar Blue and tetrazolium bromide indicators. To measure agreement the Kappa value was used. Cutoff values between sensitive and resistant strains were defined as 0.2mg/mL and 1.0mg/mL for isoniazid and rifampicin, respectively. RESULTS: There was 100% concordance between Alamar Blue and tetrazolium bromide methods in the determination of minimal inhibition concentrations. Agreement between the colorimetric method and the Lowenstein-Jensen was 95% for isoniazid and rifampicin. Using the colorimetric method, results were obtained within 7 days, in contrast to the 28 days required for the conventional method. CONCLUSIONS: Assays to determine minimal inhibition concentrations in liquid medium and employing oxidation-reduction indicators proved to be rapid and inexpensive. This method has the potential to become a faster, alternative method for determining susceptibility of M. tuberculosis strains in developing countries.
