Clinical course and outcome of antenatally detected atrioventricular block: experience of a single tertiary centre and review of the literature.

OBJECTIVE: The objective is to study the course and outcome of fetuses with congenital atrioventricular block (AVB) in a single centre. METHODS: Retrospective analysis of cases diagnosed prenatally with second and third degree AVB. The clinical characteristics and outcome of fetal AVB were evaluated including in utero treatment. RESULTS: Sixty-two cases were studied. AVB was associated with a congenital heart defect (CHD-AVB) in 17 cases (27%), whereas it was isolated (i-AVB) in 45 (73%), 42 of which were associated with maternal antibodies. There were nine (52.9%) live births in the CHD-AVB group, five of which (55%) resulted in infant deaths. In the i-AVB group, there were 40/45 (88.9%) live births and 1/40 (2.5%) infant death; 36 (90%) babies required a permanent pacemaker. The only factor predictive of postnatal death was the presence of CHD (5/9 vs 1/39 or 48.7 [3.6; 1457.7], p < 0.001). Nineteen fetuses (40.5%) with i-AVB received steroids in utero. No difference in outcome was found between the AVB treated in utero versus the no-treatment group in terms of permanent pacemaker placement, postnatal death or development of dilated cardiomyopathy. CONCLUSION: The most important prognostic factor for congenital AVB is the association with CHD. In utero treatment remains questionable.

Fetal death as a result of placental immune reconstitution inflammatory syndrome.

A 26-year-old woman was HIV-1 diagnosed at 11 weeks of pregnancy (CD4 = 7/mm(3), HIV-1 RNA = 108,000 copies/mL) with immunity against toxoplasmosis (Toxoplasma IgG = 1800 UI/mL). A fetal death was diagnosed 7 weeks after starting HAART (CD4 = 185/mm(3), HIV-1 RNA = 391 copies/mL) with a positive Toxoplasma PCR on fetal tissues and amniotic fluid. The absence of severe toxoplasmic foetopathy, the very exaggerated and atypical placental inflammation and the immune restoration context led to the diagnosis of placental IRIS associated with Toxoplasma gondii reactivation. This outcome remains undescribed and could represent an issue in resource-limited settings where HIV-pregnant patients are often severely immunodeficient and infected with opportunistic pathogens.

Very early twin-to-twin transfusion syndrome and discordant activation of the renin-angiotensin system.

We present evidence of a first-trimester discordant renin-angiotensin system (RAS) response and structural abnormalities of the kidneys in twins with twin-to-twin transfusion syndrome (TTTS). A dark red fetus and a pale fetus were spontaneously delivered at 13.5 weeks of gestation following a double intra-uterine death. Pathological examination confirmed the placentation as monochorionic, with arteriovenous anastomoses on the chorionic plate. The donor twin had a normal heart and mildly hypoplastic kidneys, and the recipient twin had cardiomegaly and hypertrophic kidneys. Immunohistochemical analysis of the kidneys showed secretion of renin occurring in the donor but not in the recipient twin, more intense expression of angiotensin II receptor type 1 in the donor, and modifications of renal architectures in both twins. Renin protein appeared qualitatively higher in the placental territory of the recipient compared to that of donor. These findings indicate that hemodynamic discordance caused by vascular anastomoses may lead to serious physiologic and organic consequences as early as the first trimester. To our knowledge, this case presents the earliest first-trimester TTTS confirmed by a complete anatomopathological examination and is the first TTTS case to show a first-trimester discordant RAS response confirmed by immunohistochemistry.

[Unusual complication of uterine leiomyoma: spontaneous avulsion with massive hemoperitoneum]. / Complication rare d'un léiomyome utérin: énucléation spontanée avec hémopéritoine.

A 25-year-old woman gravida 0 was seen for haemoperitoneum secondary to spontaneous avulsion of a uterine leiomyoma. It is a life-threatening complication. A myomectomy was performed. Through a case, we report a revue of the literature of haemoperitoneum complicating uterine leiomyoma.

Prenatal diagnosis of a congenital bladder diverticulum. Case report and benefits of prenatal diagnosis.

A case of congenital bladder diverticulum diagnosed at 37 weeks of gestation (measured from the first day after the last day of the last menstrual period) is reported. Delivery took place 24 h later. A postnatal urologic work-up confirmed the diagnosis of asymptomatic congenital bladder diverticulum. The infant underwent laparotomic surgery at the age of 6 months, with an extravesical diverticulectomy and ureteral reimplantation. There were no complications. This is the first case reported in the literature of a prenatal diagnosis of a congenital bladder diverticulum. This new aspect allows early management and avoidance of the diagnostic meanders to which the discovery of a pelvic mass might lead, as well as the complications that can follow bladder diverticula.
