RESUMO
Triatoma infestans is one of the main vectors of Chagas disease in Latin America. Although the species is under control in most Latin countries, it is still necessary to maintain epidemiological surveillance. The present study aims to characterize T. infestans populations from residual foci in Bahia and Rio Grande do Sul, Brazil, comparing them with natural populations in Argentina and Bolivia. For this, we adopt the geometric morphometry of the heads. It is possible to report the morphometric variety of the studied populations. In addition, we show that the size of the heads contributes to the differentiation between populations, while the shape has less power to discriminate groups. Furthermore, we show that some natural populations have morphometric proximity to residual populations, suggesting a relationship between these triatomines. Our data do not support the origin of residual populations but demonstrate the importance of new studies with other techniques to understand the dynamics of distribution and reintroduction of these vectors in Brazilian territory.
RESUMO
INTRODUCTION: This study reports the first occurrence of Psammolestes tertius (Hemiptera, Reduviidae, Triatominae) in the state of Sergipe, Brazil. METHODS: In 2020, 95 specimens were collected from the municipality of Porto da Folha, Sergipe, Brazil. RESULTS: This finding expands the geographical distribution of the species from 15 states in Brazil to 16 and increases the biodiversity of triatomines in the state of Sergipe. CONCLUSIONS: The presence of P. tertius in the state of Sergipe demonstrated a wider distribution of this species in northeastern Brazil.

OBJECTIVE: To analyze and follow-up patients previously selected by pediatricians at the time of birth who presented altered initial physical examination results to identify the pathological changes in their hips. METHODS: A prospective cohort study was conducted involving 34 newborns (68 hips) out of a total of 1273 live births; these infants were assessed within the first days of life as altered findings were noted in the initial examination by the pediatrician. The results of clinical and ultrasonographic examination performed using the GRAF method and of specific treatments were analyzed. RESULTS: Of the 68 hips in 34 patients, 2 hips in 2 patients required intervention using the Pavlik harness for 8 weeks; a satisfactory treatment outcome was obtained in both cases. CONCLUSIONS: Despite the low orthopedic workload in medical courses, it was possible to identify data consistent with the literature, both in the presentation of clinical findings and in those that required treatment, indicating that an initial evaluation of all newborns is mandatory, especially those with risk factors. Level of evidence IV, case series.
OBJETIVO: Analisar e acompanhar os pacientes previamente selecionados por pediatras desde o nascimento, em busca de alterações patológicas nos quadris, naqueles considerados com exame físico inicial alterado. MÉTODOS: Estudo de coorte prospectivo, iniciado nos primeiros dias de vida, em 68 quadris de 34 recém-nascidos, de um total de 1.273 nascidos vivos no ano da pesquisa, devido a alguma alteração no exame inicial do pediatra. Primeiramente, foram utilizados exame clínico e ultrassonográfico, com o método de Graf, tendo sido instituído tratamento específico naqueles que se fizeram necessários. RESULTADOS: Dos 68 quadris em 34 pacientes, dois quadris em dois pacientes distintos necessitaram de intervenção com uso do suspensório de Pavlik por 8 semanas, obtendo resultado satisfatório em ambos após o término do tratamento. CONCLUSÃO: Apesar da baixa carga horária da Ortopedia nos cursos de medicina, podem-se observar dados condizentes com a literatura, tanto na apresentação de achados clínicos, quanto nos que se fez necessário o tratamento, de forma que se mostra necessária a realização de avaliação inicial adequada de todos os recém-nascidos, em especial naqueles que possuem fatores de risco. Nível de evidência IV, Série de casos.
