Background: Impetigo herpetiformis (IH) is a rare skin disorder that occurs during pregnancy. It was previously associated with high maternal and fetal mortality and morbidity, but now has a better prognosis. Case Report: We report a case of a pregnant woman with IH who presented with generalized erythematous pustular eruptions in the 32nd week of gestation. The IH progressed rapidly, and gestational hypertension was observed in the 36th week. The lesions did not subside, despite treatment with corticosteroids and phototherapy. She delivered a healthy male baby via cesarean section in the 37th week. One month after her delivery, her skin returned to normal, except for residual pigmentation, with complete recovery 3 months postpartum. Conclusion: An experienced medical team comprising obstetricians, dermatologists, perinatologists and neonatologists is critical to aggressively treat this life-threatening specific dermatosis of pregnancy and to prevent ensuing complications, such as fluid and electrolyte imbalance, secondary infection and placental insufficiency.
Pregnancy with pulmonary hypertension (PH) seriously threatens the life and safety of mothers and infants. Here, the long-term effect of maternal PH on the postpartum growth of rat offspring was focused for the first time, as well as explored the role of Myadm in PH rats before pregnancy based upon the previous findings. Patients with PH are prone to hypoxemia, leading to insufficient placental structure and function, which affects the organ function of fetuses, followed by evidence that differently expressed genes (DEGs) existed in the heart of maternal PH newborn rats and enriched in pathways related to cardiac and nerve development on human infants with similar birth outcome: low birth weight (LBW). LBW was one of the possible birth outcomes of pregnancy with PH, especially severe PH, accompanied by evidence that offspring derived from mothers with PH presented lower birth weights and slower growth rates than those derived from normal control mothers in a rat model. Besides, maternal PH rat offspring showed cardiac remodeling and a significant elevation of the expression levels of hypoxia- and inflammation-related markers in the cerebral cortex at both 10 and 14 weeks of age, respectively. What is more, the previous studies found that the overexpression of Myadm could result in the remodeling of the pulmonary artery. And targeting Myadm to intervene PH before pregnancy could alleviate sustained low weight growth in maternal PH rat offspring, and the pathological changes of the cardiac–cerebral system caused by maternal PH, including enlarged right heart cavity, loss of cardiomyocytes, abnormal heart index, as well as cerebral cortex hypoxia and the inflammatory state as they grew up to a certain extent. The findings show the pathological significance of maternal PH on offspring growth and the cardiac–cerebral development in a rat model, as well as point out the potential treatment target, which may provide a further reference for pregnancy outcomes in women with PH and healthy development of offspring to some extent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
