The presence of fluoride in drinking water can be either beneficial or harmful for human health, depending on its concentration. Most adverse effects of fluoride are observed at high concentrations (above 1.5 mg/L). This study was aimed to evaluate the effect of fluoride concentrations in drinking water on spontaneous abortion in two regions: one with low fluoride concentration and another with high fluoride concentration. The results showed that there is a relationship between the concentration of fluoride in drinking water and abortion, so that the risk of abortion increased at high concentrations of fluoride...

Insular gliomas were previously considered inoperable lesions and were typically treated via biopsy, chemotherapy and/or radiation, if not observation alone. Stereotactic biopsies of low grade insular gliomas can underestimate tumor grade or fail to establish malignancy. Moreover, the survival advantages of maximal safe resection for insular lesions are increasingly being recognized. As such, early surgical resection is increasingly being performed. As with most lesions, a differential diagnosis exists for apparent insular gliomas, with definitive diagnosis generally obtained upon resection...

It has been proposed that transcobalamin 2 (TCN2) and the transcobalamin 2 receptor (TCN2R) are associated with idiopathic recurrent spontaneous abortion (RSA). The aim of the present study was to investigate the impact of TCN2 rs1801198 and TCN2R rs2336573 polymorphism on RSA in a sample of Iranian population. This case-control study was done on 92 RSA patients and 93 normal, fertile women. Genotyping of the TCN2 rs1801198 and TCN2R rs2336573 variants was done by polymerase chain reaction restriction fragment length polymorphism (PCR-RFLP)...

Women (n = 300) at 'low risk' for a preterm birth (PTB), a singleton pregnancy and for a 16-24 week period of gestation (POG) were randomised to undergo cervical length (CL) measurement by transvaginal sonography (TVS) or not. The aim was to see if routine CL measurement and treatment of a short CL reduced the PTB rate. 'Low risk' was defined by an absence of a prior abortion or PTB of a singleton infant (>16 to <37 weeks) due to a spontaneous preterm labour (PTL) or a preterm pre-labour rupture of membranes (pPROM)...

With fewer than 200 reported cases, Cushing's syndrome (CS) in pregnancy remains a diagnostic and therapeutic challenge. In normal pregnancies, misleading signs may be observed such as striae or hypokalemia, while plasma cortisol and urinary free cortisol may rise up to 2-3-fold. While the dexamethasone suppression test is difficult to use, reference values for salivary cortisol appear valid. The predominant cause is adrenal adenoma (sometimes without decreased ACTH), rather than Cushing's disease. There are considerable imaging pitfalls in Cushing's disease...

BACKGROUND: First deliveries in women older than 35, 40, or 45 are at increased risk for adverse pregnancy outcomes compared with those in younger women. However, specific relationships between each additional year of maternal age and pregnancy risks remain unclear, and absolute risks at each maternal age are not known. METHODS: Using a population-based cohort of nulliparous women in British Columbia, Canada, from 2004-2014 (n=203,414), We examined relationships between maternal age (modeled flexibly to allow curvilinear shapes) and pregnancy outcomes using logistic regression...

Osseous metaplasia of the endometrium is a rare condition characterized by the presence of mature or immature bone in the endometrium. Most cases present with secondary infertility following an abortion or chronic endometritis. Some patients are asymptomatic, while others have menstrual abnormalities such as menorrhagia or oligomenorrhea. Removal of the bony fragments helps in spontaneous conception. We hereby present two cases of osseous metaplasia of the endometrium with radiological and pathological correlation...

BACKGROUND: Spontaneous abortions are the most common complication of pregnancy. Clotrimazole and miconazole are widely used vaginal-anti-mycotic agents used for the treatment of vulvovaginal candidiasis. A previous study has suggested an increased risk of miscarriage associated with these azoles, which may lead health professionals to refrain from their use even if clinically indicated. The aim of the current study was to assess the risk for spontaneous abortions following first trimester exposure to vaginal-anti-mycotics...

Stress during pregnancy increases the risk to develop psychological disorders such as depression during pregnancy or in the postpartum period. According to the neurotrophin hypothesis of depression, the pathophysiology of depression is caused by reduced neurotrophic activity in the brain. However, most studies only focus on the molecular changes happening to the offspring upon gestational stress. To gain insight into the potential molecular changes happening in the stressed dams, C57Bl6/J mice were stressed during their first week of gestation...

PROBLEM: To explore whether IL-33/ST2 axis modulates the polarization and efferocytosis of decidual macrophages (dMφs). METHOD OF STUDY: The phenotype characteristics of dMφs from both normal pregnant women and recurrent spontaneous abortion (RSA) patients were determined by real-time polymerase chain reaction (RT-PCR) and flow cytometry (FCM). Then, the efferocytosis and expression of IL-33 and its receptor (ST2) in dMφs were analyzed by FCM. Finally, the effects of sST2, a decoy receptor for IL-33 that inhibits the IL-33/ST2 signaling pathway, on the polarization and efferocytosis of dMφs and human macrophage cell line U937 were investigated...

Melatonin is a neurohormone synthesized from the aromatic amino acid tryptophan mainly by the pineal gland of mammals. Melatonin acts as a broad-spectrum antioxidant, powerful free radical scavenger, anti-inflammatory agent, anticarcinogenic factor, sleep inducer and regulator of the circadian rhythm, and potential immunoregulator. Melatonin and reproductive system are interrelated under both physiological and pathological conditions. Oxidative stress, inflammation, and immune dysregulation are associated with the pathogenesis of the female reproductive system which causes endometriosis (EMS), recurrent spontaneous abortion (RSA), and polycystic ovary syndrome (PCOS)...

Introduction: Pregnancy is an immune paradox. While the immune system is required for embryo implantation, placental development and progression of gestation, excessive inflammation is associated with pregnancy failure. Similarly, the cytokine IL-17A plays an important role in defence against extracellular pathogens, but its dysregulation can lead to pathogenic inflammation and tissue damage. Although expression of IL-17 has been reported during pregnancy, the cellular source of this cytokine and its relevance to gestation are not clear...

In the present study, the mechanisms underlying the pathogenesis of unexplained recurrent spontaneous abortion (URSA) were explored. The protein and mRNA expression of two C-type lectin-like receptors (CLRs), namely dendritic cell-specific intercellular adhesion molecule-3-grabbing non-integrin (DC-SIGN) and mannose receptor (MR), and two Toll-like receptors (TLRs), namely TLR2 and TLR4, in the decidua and dendritic cells (DCs) was compared between URSA patients and normal controls. URSA patients had significantly lower protein and mRNA expression of DC-SIGN and significantly higher expression of TLR2 and TLR4 in decidual tissues compared with normal controls...

Diclofenac is a widely used analgesic so that exposure during pregnancy may frequently occur. Most publications have evaluated the safety of NSAIDs on pregnancy outcome as a group of substances. Specific data on diclofenac are rare. This observational cohort study used the German Embryotox pharmacovigilance database to assess the risk of major birth defects and spontaneous abortion after first trimester exposure to diclofenac. A group of 260 women who took diclofenac during first trimester was compared to 778 non-exposed pregnancies...
