Vulvovaginal candidiasis (VVC), particularly the recurrent form, remains an intractable problem for clinicians, microbiologists, and patients. It is essential to confirm the clinical diagnosis by mycological methods and avoid empirical therapy. The recovery of yeast in fungal culture, such as on Sabouraud dextrose agar, remains the gold standard for diagnosis. In this investigation, we examined 474 participants, including 122 (25.7%) with acute VVC cases, 249 (52.5%) who had recurrent VVC (RVVC) cases, and 103 (21.7%) healthy controls. We also administered a questionnaire to obtain information on patient lifestyle and medical, gynecological, and sexual history. In addition, we compared the performance of chromID Candida agar (CAN2) to CHROMagar Candida (CAC) and Sabouraud dextrose agar with gentamicin and chloramphenicol (SGC2). The yeasts were identified by conventional methods including the germ tube test, microscopic morphology on cornmeal-Tween 80 agar, and the commercial API 20C AUX system. We detected yeasts in 60 of 122 (49.2%) patients with acute VVC cases, 110 of 249 (44.2%) with RVVC cases, and in 35 of 103 (34%) healthy controls (P = 0.07). A total of 205 samples were found to be positive for fungi (43.2%), of which 176 (85.9%) were monofungal, and 29 (14.1%) were polyfungal. In addition, 198 of these samples (96.6%) were positive on CAN2, 195 (95.1%) on CAC, 189 (92.2%) on SGC2, and 183 (89.3%) samples on all three (P = 0.17). The 234 yeast isolates recovered were C. albicans (n = 118), C. glabrata (n = 82), C. kefyr (n = 11), C. krusei (n = 9), C. lipolytica (n = 3), C. colliculosa (n = 2), C. parapsilosis (n = 2), C. pelliculosa (n = 2), C. tropicalis (n = 2), and other species of Candida (n = 3). Of the 29 polyfungal populations, 28 (96.6%) were detected in CAN2, 25 in (86.2%) CAC, and 25 (86.2%) on both (P = 0.35). Notably, we detected the high predominance of C. albicans+C. glabrata (86.2%) in polyfungal populations. Briefly, the detection of C. albicans after 24 h of incubation was easier on CAN2 (64.4%) than on CAC (25.4%). This study showed that CAN2 is a rapid and reliable medium for immediate identification of C. albicans and for detecting polyfungal populations in vaginal specimens. We observed that the use of antibiotics, intrauterine devices, as well as, perineal laceration, short anovaginal distance (< 3 cm), and genital epilation in common areas are predisposing factors for RVVC (P < 0.001). In addition, we detected that the use of menstrual pad, using an (IUD), and having a history of childbirth increased the risk of both acute and recurrent VVC (P < 0.01), whereas the use of a daily pad and walking daily significantly decreased the risk of both acute and recurrent VVC (P < 0.01).

Objective: To compare clinical and laboratory findings between the early-onset preeclampsia (EOP) and late-onset preeclampsia (LOP). Methods: This prospective longitudinal study was performed at a tertiary referral university clinic. All patients meeting the inclusion criteria were divided into two groups, the EOP group and the LOP group, according to gestational age at the onset of disease. The distinction criterion for early versus late onset was set as week 34 of gestation. Clinical and laboratory findings, and maternal–perinatal outcomes were compared between the groups. Results: A total of 157 patients with preeclampsia were included. A significant difference was observed between the groups in terms of diagnosis and severity of the disease (p = 0.007 and <0.001, respectively). The history of previous preeclampsia, diastolic blood pressure and hourly urine output on admission to the hospital were significantly different between the groups (p = 0.016, 0.018 and 0.024, respectively). Latent period for delivery and postpartum hospitalization time were longer in the EOP group than in the LOP group (p = 0.024 and 0.002, respectively). The patients with EOP received betamethazone (p < 0.001) and MgSO4 (p = 0.029) more frequently. Neonatal characteristics such as birth weight, low APGAR score and admission to neonatal intensive care unit were significantly different between the groups (p < 0.001, for all variables). Total proteinuria at 24 h was found significantly higher in the EOP group than in the LOP group (p = 0.012). Conclusion: The results confirmed the opinion that EOP is a distinct and more severe clinical entity than LOP. In particular, higher proteinuria is associated with EOP.

Context: Recent studies have suggested a direct contribution of nicotine − the addictive component of tobacco and tobacco smoke − to human carcinogenesis, and it remains the most common harmful substance to which pregnant women are exposed. Also, it has deleterious effects on the fetus. The sperm of smoking fathers and newborns of smoking mothers have elevated frequencies of chromosome translocations and DNA strand breaks. Objective: We tried to understand the genotoxic effect of nicotine in pregnancies of active or passive smoking mothers. For this reason, we provide the evidence that nicotine exposure in vitro has detrimental effects on fetal cells. Materials and methods: We examined the effect of nicotine sulphate on amniotic cells by designing an experimental setting consisting fetal cells grown in nicotine containing medium (25 ng/mL) in study group and fetal cells grown in control medium, which did not contain nicotine. Results: According to our findings, there is a significant difference of chromosomal aberrations (CAs) between nicotine containing medium grown cells and control medium grown cells, determined by the χ2 test (P <0.001). We found CAs in 21.5% of cells analyzed. The 19.4% of the all cells had numerical aberrations. Chromosomes 21, 22, 8, 15 and 20 related numerical abnormalities were found to be the most frequent numerical abnormalities. Conclusion: Results of this study confirm that the nicotine leads to significant direct genotoxic effects in human fetal cells in vitro. We speculate that there is an association between prenatal exposure to cigarette smoke and in utero aneuploidies.
