Surgical management of neurovascular bundle in uterine fibroid pseudocapsule.

The authors propose that intracapsular myomectomy be recommended to maximize the potential for future fertility and to minimize the risk of labor dystocia or uterine rupture during pregnancy or labor.

Systematic review and meta-analysis on persistent left superior vena cava on prenatal ultrasound: associated anomalies, diagnostic accuracy and post-natal outcome.

To quantify the prevalence of chromosomal anomalies in fetuses with persistent left superior vena cava (PLSVC), assess the strength of the association between PLSVC and coarctation of the aorta and ascertain the diagnostic accuracy of antenatal ultrasound in correctly identifying isolated cases of PLSVC.

Detection of Residual/Recurrent Cervical Disease after Successful LEEP Conization: the Possible Role of mRNA-HPV Test

BACKGROUND Loop Electrosurgical Excision Procedure (LEEP) represents the mainstay technique for CIN2+ removal. The major concern in conservative treatment is to verify whether CIN eradication was complete, since incomplete excision is associated with an increased risk of cervical cancer. The histopathologic evaluation of resection margins status is far from perfect, since cervical lesions may recur in 5-15% of patients who had conisation specimens with clean margins. Current follow-up protocol of patients treated by conisation for high grade CIN is manly based on the combination of cytology-plus- HPV-DNA testing. This approach showed high sensitivity but low specificity level in detecting recurrence. The consequence were overdiagnosis and overtreatment, especially in youngest women, in which spontaneous regression rate of CIN is substantial. In this longitudinal study we investigated whether patients age, cone depth and pre-conisation HPV-load level, may be used as predictive markers for residual/recurrent CIN after conisation. Then we aimed to examined the role of E6/E7 mRNA testing during post-conization follow-up. METHODS The study, focused on the outcome of 116 patients treated for CIN by LEEP, included three consecutive steps. Firstly, the authors analysed the prevalence of residual/recurrence disease after conization; then, they investigated which factors may influence treatment failure even when resection margins were clean; finally, they evaluated the diagnostic accuracy of E6/E7 mRNA test as predictive marker of recurrence. RESULTS HPV infection was detected in 31% of patients at 6-month follow-up and in 11.2% of patients, at 24-month follow-up. Younger women showed higher rate of recurrence than older ones. The risk of residual/recurrent infection did not correlate with cone-depth. Recurrence is higher in patients with low viral load level than in those having high load levels. mRNA test showed higher specificity and positive predictive value than the combination cytology-plus-HPV-DNA test. CONCLUSION The inclusion of mRNA test within the current protocol of follow-up would efficiently and earlier predict the risk of residual/ recurrent cervical abnormalities after conisation. This molecular strategy would also reduce overtreatment, particularly in patients above 30 years of age.

Intrapartum sonographic signs: new diagnostic tools in malposition and malrotation

Abstract In the past years, numerous studies have been published on the use of ultrasound during labor, showing this is an effective, accurate and objective tool for the assessment of the fetal head position and station. Literature affirmed that traditional transvaginal digital examination is highly subjective and dependent on the operator’s experience. On the contrary, the use of intrapartum suprapubic transabdominal ultrasound can improve accuracy in determination of fetal head position and the precise knowledge of the location of specific fetal head landmarks in relationship to maternal pelvis. Intrapartum ultrasound will assist obstetricians in the diagnosis of normal labor progression, suggesting when medical and or operative intervention should be taken in case of complications. During each fetal head movement, there is a very specific relationship between fetal head landmarks and well-identified maternal structures, so the ultrasound diagnosis is performed step by step. In this review, we summarized the clinical situation of the fetal head in the pelvis and the relative ultrasonographic signs. Moreover, we collected all the ultrasonographic measures to diagnose the fetal head progression and rotations in the birth canal.

Molecular alterations in endometrial archived liquid‐based cytology

Endometrial cancer is one of the most common gynecological malignancy worldwide and its prevalence is increasing. The introduction of liquid‐based cytology (LBC) and endoflower dispositive in routine practice gives the possibility to examine endometrial cells by cytological diagnosis and may also release the opportunity to study molecular alterations, in endometrioid type cancer in which carcinogenesis is well known. We gathered 72 cases of endometrial LBC samples and corresponding formalin‐fixed paraffin‐embedded (FFPE) blocks, collected from 2004 to 2010. DNA was isolated from both samples using standard protocols. DNA quality and quantity were assessed using Nanodrop and BIOMED2 multiplex PCR. Mutations in exon 5 of PTEN and exon 20 of PI3K were studied using Sanger sequencing. DNA with good quality and amount was isolated from 67/72 FFPE cases. In these samples, two cases were found to harbor mutations in exon 5 of PTEN. No PI3K mutations were identified. LBC samples were then assessed to verify the concordance with the FFPE DNA results. The results obtained were concordant, that is the wild type cases in FFPE were also wild type in LBC and vice versa for the mutated case. Unfortunately, the second case of mutation in PTEN could not be confirmed in LBC due to low amount of DNA obtained. Detection of molecular alterations in LBC will open a new era for the detection in asymptomatic women of precursor lesions that could evolve into cancer and for endometrial cancer diagnosis and screening in selected high‐risk women.

NEUROTRANSMITTERS AND NEUROPEPTIDES EXPRESSION IN THE UTERINE SCAR AFTER CESAREAN SECTION.

Peptides and neuropeptides influence the uterine disorders of healing or cicatrization, chronic pelvic pain and disorder of pregnancy, labor and puerperium. They also promote changes in the lower uterine segment (LUS) during pregnancy, labor and delivery. We investigated the tissue quantity of neurotensin (NT), neuropeptide tyrosin (NPY) and Protein Gene Product 9.5 (PGP 9.5) in women submitted to elective cesarean section (CS) and urgent CS. During surgery, authors biopsied tissue samples of vesico-uterine space (VUS) to detect nerve fibers, and compared them. VUS samples from 106 patients have been evaluated with light microscopy, immunochemistry and Immunohistochemistry, and finally by Quantimet Leica analyzer software. Significantly higher amount of nerve fibers, containing NT, NPY and PGP 9.5 have been found in VUS tissue samples obtained during the first elective CS and during the first urgent CS were respectively 5±0.7, 7±0.6 and 5±0.9 CU and 2.5±0.5, 3.6±0.4 and 3.5±0.9 CU (p<0.05). This neurotransmitter reduction should indicate the inflammatory damage of cervical tissue for LUS over distension in dystocic-prolonged labor before CS. These results may be correlated with the decrease of NT, NPY and PGP 9.5, responsible for an optimal healing and LUS functions. In our opinion, the presence of neuropeptides reduction in uterine samples of women undergoing urgent CS may be due to a prolonged fetal head station in LUS, with a tissue denervation, in consequence of both overdistension and inflammatory process of the dystocic LUS.
