Background: This study investigated the association between pesticide exposure in Brazil (2005-2013) with rates of central nervous system (CNS) and cardiovascular system (CVS) congenital abnormalities in 2014.
Method: An exposure variable was established from data on production and sales of pesticides (kg) per crop area (ha) for 2012 and 2013 years. The Brazilian states were divided into three categories: high, medium, and low pesticide use and rate ratios were estimated for each group of states (CI: 95 %).
Results: In 2013 and 2014, the high use group presented a 100 and a 75 % increase, and the medium group a 65 and 23 % increase, respectively, in the risk of CNS and CVS congenital abnormalities at birth, compared to the low use group.
Conclusion: These findings suggest that pesticide exposure could be associated with increased risk of congenital malformations at birth in Brazil.

Introduction: The advancements in neonatal resuscitation and surgical care have enabled children with congenital abnormalities to receive corrective surgeries and achieve lifespans well into adulthood. These patients may require long-term follow-up as they continue to have risks of developing sequelae from their original diseases or surgical interventions.
Purpose: This study aimed to investigate the current practice and barriers to the transition of care (TOC) from the perspectives of adult surgeons.

Pre- and postoperative photos to assess results are widely used in plastic and reconstructive surgery, for instance, in patients with cleft lip and palate (CL/P). Evaluations are often performed by assessment panels by viewing the photos. However, these are prone to be subjective.

Most of the malformations of the polymicrogyria spectrum are caused by destructive lesions of the neocortex during the third trimester of pregnancy, triggered by hypoxic-ischemic, hemorrhagic or infectious events, with neuroinflammation as a common pathophysiological mechanism. Our study investigated hydrocortisone treatment in attenuating inflammation, malformations development and seizures predisposition in mice subjected to neonatal transcranial freeze lesion. Our results show attenuation of malformation and predisposition to febrile seizures, with concomitant reduction of macrophages/microglia after neonatal freeze lesion, polarizing them towards an anti-inflammatory profile.
