RESUMO
OBJECTIVES: To describe placental findings on prenatal ultrasound and anatomopathological examination in women with Zika virus (ZIKV) infection, and to assess their association with congenital ZIKV infection and severe adverse outcome, defined as fetal loss or congenital Zika syndrome (CZS). METHODS: This was a prospective study of pregnancies undergoing testing for maternal ZIKV infection at a center in French Guiana during the ZIKV epidemic. In ZIKV-positive women, congenital infection was defined as either a positive reverse transcription polymerase chain reaction result or identification of ZIKV-specific immunoglobulin-M in at least one placental, fetal or neonatal sample. Placental ZIKV-infection status was classified as non-exposed (placentae from non-infected women), exposed (placentae from ZIKV-infected women without congenital infection) or infected (placentae from ZIKV-infected women with proven congenital infection). Placentae were assessed by monthly prenatal ultrasound examinations, measuring placental thickness and umbilical artery Doppler parameters, and by anatomopathological examination after live birth or intrauterine death in women with ZIKV infection. The association of placental thickness during pregnancy and anatomopathological findings with the ZIKV status of the placenta was assessed. The association between placental findings and severe adverse outcome (CZS or fetal loss) in the infected group was also assessed. RESULTS: Among 291 fetuses/neonates/placentae from women with proven ZIKV infection, congenital infection was confirmed in 76 cases, of which 16 resulted in CZS and 11 resulted in fetal loss. The 215 remaining placentae from ZIKV-positive women without evidence of congenital ZIKV infection represented the exposed group. A total of 334 placentae from ZIKV-negative pregnant women represented the non-exposed control group. Placentomegaly (placental thickness > 40 mm) was observed more frequently in infected placentae (39.5%) than in exposed placentae (17.2%) or controls (7.2%), even when adjusting for gestational age at diagnosis and comorbidities (adjusted hazard ratio (aHR), 2.02 (95% CI, 1.22-3.36) and aHR, 3.23 (95% CI, 1.86-5.61), respectively), and appeared earlier in infected placentae. In the infected group, placentomegaly was observed more frequently in cases of CZS (62.5%) or fetal loss (45.5%) than in those with asymptomatic congenital infection (30.6%) (aHR, 5.43 (95% CI, 2.17-13.56) and aHR, 4.95 (95% CI, 1.65-14.83), respectively). Abnormal umbilical artery Doppler was observed more frequently in cases of congenital infection resulting in fetal loss than in those with asymptomatic congenital infection (30.0% vs 6.1%; adjusted relative risk (aRR), 4.83 (95% CI, 1.09-20.64)). Infected placentae also exhibited a higher risk for any pathological anomaly than did exposed placentae (62.8% vs 21.6%; aRR, 2.60 (95% CI, 1.40-4.83)). CONCLUSIONS: Early placentomegaly may represent the first sign of congenital infection in ZIKV-infected women, and should prompt enhanced follow-up of these pregnancies. Copyright © 2019 ISUOG.

OBJECTIVE: Female genital mutilation (FGM) covers all procedures involving partial or total removal of the external genitalia for non-therapeutic purposes. The period of pregnancy and childbirth is probably more at risk of complications for these women. The main aim of this study was to compare obstetrical, maternal and neonatal outcomes in patients with a history of female genital mutilation with patients without such a history. METHODS: All deliveries taking place between January 2005 and June 2022 at Besançon University Hospital in patients with a history of FGM were included. This group was compared with a randomly selected group of deliveries of patients with no history of FGM. A total of 87 deliveries with a history of FGM were included and compared with 696 deliveries with no history of FGM. RESULTS: There were significantly more instrumental deliveries (27.6% vs. 17.5%, P=0.01), more caesarean sections (23% vs. 14.1%, P=0.01), more episiotomies (9.2% vs. 0.7%, P<0.01), more first-degree perineal tears (30.8% vs. 20.8%, P=0.02), second-degree (13.9% vs. 5.3%, P<0, 01), third-degree (3.1% vs. 0.2%, P=0.02), more anterior perineal tears (23.1% vs. 2.5%, P<0.01), increased duration of pushing efforts (13 min vs. 10 min, P=0.05) and greater blood loss (297 cc vs. 165 cc, P<0.01) in the group with a history of FGM. There was no statistically significant difference in neonatal outcome. CONCLUSION: The obstetrical prognosis of patients with a history of FGM is significantly poorer. Neonatal prognosis remains unchanged.

BACKGROUND: Despite being first identified in 1947, Zika virus-related outbreaks were first described starting from 2007 culminating with the 2015 Latin American outbreak. Hypotheses indicate that the virus has been circulating in Asia for decades, but reports are scarce. METHODS: We performed serological analysis and screened placental samples isolated in 2008 for the presence of Zika virus from pregnant women in Ho Chi Minh City (Vietnam). RESULTS: None of the placental samples was positive for Zika virus. Four serum samples out of 176 (2.3%) specifically inhibited Zika virus, with variable degrees of cross-reactivity with other flaviviruses. While one of the four samples inhibited only Zika virus, cross-reactivity with other flaviviruses not included in the study could not be ruled out. CONCLUSION: Our results support the conclusion that the virus was not present among pregnant women in the Vietnamese largest city during the initial phases of the epidemic wave.
RESUMO
BACKGROUND: We report here a case of a healthy 23-year-old female patient who was assessed at the gynecology emergency department for genital ulcers, fever, and blurred vision. After suspicion of herpes simplex virus-2 lesions, the diagnosis of Behçet's disease was made. We report this case with the aim of including Behçet's disease in the differential diagnosis of genital ulcers, and emphasize the emergency of the vision loss that can be irreversible. CASE PRESENTATION: A healthy 23-year-old European female patient was assessed by gynecology in the emergency department for genital lesions associated with fever and blurred vision. At first, these lesions were suspected to be primary herpes simplex virus-2 infection One day later, she experienced decreased visual acuity in both eyes. After 4 days of worsening genital ulcers and persistent blurred vision, the patient was referred to the ophthalmology department. Fundoscopic examination showed retinal hemorrhages that were consistent with the first presentation of Behçet's disease. CONCLUSIONS: This case demonstrates that genital ulcers can be the very initial symptom of this ophthalmologic emergency. The differential diagnosis of genital ulcers is challenging. Behçet's disease should be included, especially when associated with systemic or ocular manifestations, and should be considered an emergency for the gynecologist to prevent long-term vision loss.

The intracellular bacterium Waddlia chondrophila, which belongs to the Chlamydiales order, was found to be associated with miscarriage in humans. There is little to no knowledge regarding the mode of infection, impact on the neonate and pathophysiology of this emerging bacterium. We have previously shown that W. chondrophila induces a systemic infection, organ pathology and elicits T helper type 1-associated humoral immunity in a murine model of genital infection. In the present study, we took advantage of this model of infection to evaluate the impact of this bacterium on the mouse pregnancy. We used two routes of inoculation, vaginal and intrauterine, to introduce infection before and after mating. Our results show that genital infection by W. chondrophila did not have any significant impact on gestation length and maternal weight gain, nor on the number of offspring and their weight. This observation indicates that the mouse model of infection is not suitable to study the effect of W. chondrophila on pregnancy and alternative models of infection, including in vitro ones, should be used. Moreover, an indirect immunopathological mechanism activated by this bacterium should be further explored.
RESUMO
Waddlia chondrophila and Simkania negevensis are emerging Chlamydia-related bacteria. Similar to the pathogenic organisms Chlamydia pneumoniae and Chlamydia trachomatis, these emerging bacteria are implicated in human genital infections and respiratory diseases. We used a screening strategy based on a newly developed S. negevensis-specific quantitative real-time PCR (qPCR) and a pan-Chlamydiales qPCR. We could not detect S. negevensis in 458 respiratory, genitourinary, cardiac and hepatic samples tested. One urethral swab was positive for W. chondrophila. We observed a low prevalence of Chlamydiales in respiratory samples (1/200, 0.5%), which suggests that C. pneumoniae is an uncommon respiratory pathogen. Furthermore, we screened 414 human serum samples from Switzerland, England and Israel and observed a low prevalence (<1%) of exposure to S. negevensis. Conversely, humans were commonly exposed to W. chondrophila, with seroprevalences ranging from 8.6% to 32.5%. S. negevensis is not a clinically relevant pathogen, but further research investigating the role of W. chondrophila is needed.
RESUMO
Since the 1950s, medical communities have been facing with emerging and reemerging infectious diseases, and emerging pathogens are now considered to be a major microbiologic public health threat. In this review, we focus on bacterial emerging diseases and explore factors involved in their emergence as well as future challenges. We identified 26 major emerging and reemerging infectious diseases of bacterial origin; most of them originated either from an animal and are considered to be zoonoses or from water sources. Major contributing factors in the emergence of these bacterial infections are: (1) development of new diagnostic tools, such as improvements in culture methods, development of molecular techniques and implementation of mass spectrometry in microbiology; (2) increase in human exposure to bacterial pathogens as a result of sociodemographic and environmental changes; and (3) emergence of more virulent bacterial strains and opportunistic infections, especially affecting immunocompromised populations. A precise definition of their implications in human disease is challenging and requires the comprehensive integration of microbiological, clinical and epidemiologic aspects as well as the use of experimental models. It is now urgent to allocate financial resources to gather international data to provide a better understanding of the clinical relevance of these waterborne and zoonotic emerging diseases.

Mycoplasma hominis and Ureaplasma spp. may colonize the human genital tract and have been associated with adverse pregnancy outcomes such as preterm labour and preterm premature rupture of membranes. However, as these bacteria can reside in the normal vaginal flora, there are controversies regarding their true role during pregnancy and so the need to treat these organisms. We therefore conducted a retrospective analysis to evaluate the treatment of genital mycoplasma in 5377 pregnant patients showing symptoms of potential obstetric complications at 25-37 weeks of gestation. Women presenting with symptoms were routinely screened by culture for the presence of these bacteria and treated with clindamycin when positive. Compared with uninfected untreated patients, women treated for genital mycoplasma demonstrated lower rates of premature labour. Indeed preterm birth rates were, respectively, 40.9% and 37.7% in women colonized with Ureaplasma spp. and M. hominis, compared with 44.1% in uncolonized women (Ureaplasma spp., p 0.024; M. hominis, p 0.001). Moreover, a reduction of neonatal complications rates was observed, with 10.9% of newborns developing respiratory diseases in case of Ureaplasma spp. colonization and 5.9% in the presence of M. hominis, compared with 12.8% in the absence of those bacteria (Ureaplasma spp., p 0.050; M. hominis, p <0.001). Microbiological screening of Ureaplasma spp. and/or M. hominis and pre-emptive antibiotic therapy of symptomatic pregnant women in late pregnancy might represent a beneficial strategy to reduce premature labour and neonatal complications.
