Necrotizing tracheobronchitis is a serious affection observed in ventilated newborns, frequently infants with instable hemodynamic state. It is characterized by acute episodes of airway obstruction. ⋯ The vascular theory seems to be of utmost importance in the physiopathology. Three cases are reported.

End tidal carbon monoxide levels are lower in women with gestational hypertension and pre-eclampsia.
The possible role of heme oxygenase and its byproduct carbon monoxide (CO) in the regulation of blood pressure is under investigation. The aim of this study was to compare end tidal breath CO (ETCO) levels in women with gestational hypertension (GH) or pre-eclampsia to the levels in healthy pregnant and nonpregnant women. ⋯ ETCOc levels were found to be significantly lower in women with GH/PE. Further investigation is required to determine if the lower CO levels reflect a deficient compensatory response to the increase in blood pressure or whether these are primary changes of significance to our understanding of the pathogenesis of GH/PE.
