Utility of culture and molecular methods using AllplexTM Bacterial Vaginosis Plus Assay (SeegeneⓇ) as a tool for endometriosis, infertility and recurrent pregnancy loss diagnosis.

Endometriosis, infertility, or recurrent pregnancy loss (RPL) are entities characterised by a decrease in Lactobacillus spp. and an increase in bacterial vaginosis-associated bacteria, (BVAV) according with 16S rRNA sequencing studies. However, the use of nucleic acid amplification tests (NAAT) as a tool for diagnosis algorithms is unknown. Seventy-four patients were included, with a median age of 36.5 years old (IQR: 34-39) including infertility (n=31), endometriosis (n=25), or RPL (n=18), for culturing and NAAT using the Allplex™ Bacterial Vaginosis Plus (ABVP) assay (SeegeneⓇ) with endometrial samples. The objective was determining the utility of ABVP assay for diagnosing the entities. Forty-six microorganisms were isolated from 31 out of 74 patients (41.9 %). Twenty-five endometrial samples (33.8 %) were positive for some targets included in the ABVP-assay, with median Ct value ∼37 (IQR: 31.3-37.1) and Qt value 1.43 Log10copies/reaction (IQR:1.1-2.6). For Lactobacillus species, sensitivity and specificity were 80 % and 84 %, respectively. Gardnerella vaginalis, 63.6 % and 95.7 %. No significant increase in BVAV was detected in any of the gynaecological entities. The ABVP and culture based algorithm did not show utility as a tool for endometriosis, infertility, or RPL diagnosis.

Síndrome de Herlyn-Werner-Wünderlich y diagnóstico tardío: a propósito de un caso / Herlyn-Werner-WÜnderlich syndrome with late diagnosis: a propos of a case

Herlyn-Werner-Wünderlich syndrome is a rare congenital anomaly that affects the genitourinary system. It is defined by the triad of uterus didelphys, obstructed hemivagina, and ipsilateral renal agenesis. It consists in a Mullerian anomaly. Most patients remain asymptomatic until the menarche, when they present dysmenorrhea, pelvic pain, and a pelvic mass is noticed due to hematocolpos. We present the case of a 32-year-old patient studied for infertility. 3D transvaginal ultrasound and hysterosalpingography showed uterus didelphys and a blind hemivagina. Speculoscopy during menses revealed a normal cervix and a little orifice on the lateral vagina where blood could be seen draining from a fistulized hemivagina. The abdominal ultrasound showed ipsilateral renal agenesis, confirming the suspected diagnosis.

El síndrome de Herlyn-Werner-Wünderlich es una anomalía congénita del tracto urogenital. Se caracteriza por la tríada de útero didelfo, hemivagina obstruida y agenesia renal unilateral. La mayoría de pacientes se mantienen asintomáticas hasta la menarquia, cuando debutan con dismenorrea, dolor pélvico y masa palpable debido al hematocolpos asociado. Presentamos el caso de una paciente de 32 años en estudio por problemas de fertilidad. Se realizó estudio ecográfico 3D e histerosalpingografía, donde se observó útero bicorne completo con doble canal cervical, con impresión diagnóstica de vagina homolateral ciega. A la especuloscopia durante el periodo menstrual se observó cérvix de hemivagina normal y orificio de salida en cara lateral, por donde drenaba sangre de hemivagina ciega (probablemente fistulizada). Se realizó una ecografía abdominal que constató agenesia renal izquierda, confirmándose el diagnóstico.

Utility of Three-Dimensional Ultrasonography to Assess the Position of Essure Tubal Occlusion Device and Its Complications.

BACKGROUND: To determine the utility of three-dimensional (3D) sonography to control the position of hysteroscopic sterilizing device compared to hysterosalpingography (HSG). METHODS: A prospective observational study was carried out on 139 patients who underwent hysteroscopic tubal occlusion method between February 2012 and May 2013. Patients underwent 3D ultrasound scan to control device positioning, and they also underwent HSG as an additional control method. Comparison between both methods was carried out. RESULTS: In all, 17 (12.2%) devices were inserted due to a hydrosalpinx and 122 (87.8%) due to sterilization purposes. In 124 (89.2%) cases, sonography correlated completely to HSG findings. Sonography-positive predictive value was 89.5% to detect correct device positioning. Just 4 (2.8%) patients did not present complete tubal occlusion 3 months after device insertion; one of them presented device expulsion, 2 of them presented previous hydrosalpinx (tubal occlusion was confirmed after 6 months), and the last case rejected to undergo further controls but device seem to be effective. CONCLUSIONS: 3D sonography seems to be effective for the control of sterilization device positioning, but it also detects insertion complications and device migration. Further studies would be required to assess our findings and the role of sonography in case of hydrosalpinx.
