Diagnosis and treatment of ocular syphilis can be challenging due to the wide spectrum of clinical presentations of this sexually transmitted disease. In some cases of syphilitic panuveitis, pars plana vitrectomy (PPV) can be useful in management since it plays an important role in improving fundus examination allowing treatment of possible retinal associated lesions when vitreous inflammation is intense. We present 3 cases of patients with ocular syphilis that underwent a therapeutic PPV, vitreous sample was taken and analyzed in two of them.

Dopamine is a key neurotransmitter that links the nervous and the immune system. Bisphenol A (BPA) is an endocrine disruptor with a wide distribution in the environment that is used in the manufacturing of plastic products. Evidence shows that BPA can interfere with the central dopaminergic transmission; however, there are no previous reports of this effect outside the central nervous system.

A deep interaction between the endometrium and the invading trophoblast occurs during implantation in humans, with the acquisition of uterine receptivity to the invading embryo promoted by an elevation of pro-inflammatory cytokines in the endometrium, and the invasiveness of decidualizing endometrial stromal cells, augmented by trophoblast-derived signals. Considering that usage of angiotensin II type 1 (AT1) receptor blockers, among other renin-angiotensin system (RAS) antagonists, is associated with adverse pregnancy outcomes, here we aim to analyse the involvement of AT1 receptor in the reciprocal dialogue occurring between endometrial stroma and trophoblast cells. In human endometrial stromal cells (T-HESC) pre-incubated with a decidualization cocktail, angiotensin (Ang) II increased protein expression of prolactin and FOXO1, markers of endometrial decidualization, while promoting nuclear translocation of FOXO1.

Article Synopsis
  • Endocrine disrupting chemicals (EDCs), especially various bisphenols like BPA, can interfere with normal bodily functions and may pose a risk to public health.
  • This study investigated the relationship between maternal urinary BPA levels during pregnancy and DNA methylation in newborns, using a sample of 318 mother-child pairs from the NELA birth cohort.
  • Findings suggest that higher BPA exposure, particularly in the 24th week of pregnancy, is linked to increased LINE-1 methylation in newborns, especially boys, but the overall impact on global DNA methylation appears minimal and uncertain in biological significance.
