BackgroundChildren in developing country suffer the highest burden of pneumonia. However, few studies have evaluated associations between poverty and pneumonia.MethodsA prospective population-based study on pneumonia was carried out as part of the Latin America Epidemiological Assessment of Pneumococcus (LEAP study). Chest x-rays were obtained for children one to 35 months old with suspected pneumonia presenting to emergency care centers and hospital emergency rooms in Goiania, Brazil. Chest radiographs were evaluated according to WHO guidelines. Clustering of radiologically-confirmed pneumonia were evaluated using a Poisson-based spatial scan statistic. Associations between census socioeconomic indicators and pneumonia incidence rates were analyzed using generalized linear models.ResultsFrom May, 2007 to May, 2009, chest radiographs were obtained from 11 521 children with clinical pneumonia; 3955 episodes were classified as radiologically-confirmed. Incidence rates were significantly higher in very low income areas (4825.2 per 105) compared to high income areas (1637.3 per 105). Spatial analysis identified clustering of confirmed pneumonia in Western (RR 1.78; p = 0.001) and Southeast (RR 1.46; p = 0.001) regions of the city, and clustering of hospitalized pneumonia in the Western region (RR 1.69; p = 0.001). Lower income households and illiteracy were associated with pneumonia incidence.ConclusionsIn infants the risk of developing pneumonia is inversely associated with the head of household income and with the woman educational level. Areas with deprived socioeconomic conditions had higher incidence of pneumonia and should be targeted for high vaccination coverage.

Under programme conditions the effectiveness of Hib conjugate vaccine in infants with radiologically confirmed pneumonia was 31% (95% CI: -9%, 57%) showing the potential benefit of Hib immunization in the prevention of likely non-bacteraemic pneumonia.

Um amplo espectro de anomalias congênitas pode afetar qualquer nível do trato gastrintestinal, do esôfago ao ânus. A atresia é uma importante causa de obstrução gastrintestinal, com alta taxa de morbidade em recém-natos. Há diversos mecanismos patológicos possíveis para explicar esta malformação e duas explicações clássicas de sua gênese são um defeito de recanalização do tubo intestinal ou uma interrupção no suprimento sanguíneo durante a vida intra-uterina. Os autores fazem uma revisão da literatura com ensaio iconográfico dos achados de imagem em crianças com atresia do trato gastrintestinal.

Apresentamos um caso de uma criança com dois anos e oito meses de idade,acometida pela forma recessiva da displasia craniometafisária. São enfatizados os achados clínico-radiológicos, bem como seus principais diagnósticos diferenciais, baseados em dados de breve revisão literária.
