[Secular trend in infant deaths by congenital malformations in Argentina (1980-2018)].

Introduction: Congenital malformations (CM) represent the second cause of infant death in Argentina.

Objective: To analyze the secular trend (1980-2018) of infant deaths due to CM at the regional and provincial level.

Material And Methods: The data come from the DEIS (Ministry of Health) and include the absolute number of deaths and live births and deaths by CM coded according to ICD-10 (Codes Q00-Q99).

Microcephaly infant mortality in Brazil before zika outbreak.

Introduction: We present temporal and spatial variation of deaths from microcephaly in children under 1 year of age is analyzed at regional, state, and municipal level in the pre-Zika period in Brazil.

Materials And Methods: Data on births and deaths of infants with microcephaly was obtained from DATASUS from 1996 to 2013. Infant mortality rate from microcephaly (IMR-M) was estimated at Region, Federative Unit (UF), and Municipality level.

[Spatial and temporal analysis of infant mortality from microcephaly in Argentina (1998-2012)].

Due to the increase in cases of microcephaly caused by Zika virus in Brazil, the Ministry of Health of Argentina recommends increasing surveillance of this malformation. In order to deepen the knowledge of the epidemiological behavior of microcephaly in the country, infant mortality by microcephaly is analyzed between 1998 and 2012. The data come from the Direction of Statistics and Health Information (DEIS).

[Infant mortality from congenital malformations in Chile: temporal and spatial analysis, 1997-2011].

Objective: To analyze the spatial and temporal distribution (1997-2011) of infant mortality resulting from congenital malformations (CM) in Chile.

Methods: Data on births and deaths among infants aged less than one year using ICD-10 coding were obtained from the National Statistics Institute. The percentage of deaths from CM (PD-CM) and the infant mortality rate from CM (IMR-CM) during three different periods (1997-2001, 2002-2009, 2007-2011) were estimated for Chile's administrative and natural regions (Norte Grande, Norte Chico, Central, Austral, and Sur), broken down by systems (nervous, cardiovascular, digestive, genitourinary, musculoskeletal, and chromosomal abnormalities) and by 28 specific malformations.
