    No full text
    Epithelioid sarcomas (ES) are rare soft issue tumours of obscure histogenesis. Diagnosis is often difficult as specific morphological and immunohistochemical patterns do not exist. Two distinct clinico-pathological entities have been identified: the classic or distal type and the proximal type. Recently, immunohistological detection of Ca 125 was described in ES, as well as loss of INI 1 expression. The authors describe in this paper the morphological and immunohistochemical features of two cases of priximal ES of the vulva. Immunoreactivity for CA 125 and loss of INI 1 expression were present in both cases. These results confirm previous observations in Asian reports showing that these markers can be used as immunohistochemical markers for the diagnostic assessment of ES

    Purpose: to assess the effects of the combination of pelvic floor rehabilitation, intravaginal estriol and Lactobacillus acidophil administration on stress urinary incontinence (SUI), urogenital atrophy and recurrent urinary tract infections in postmenopausal women. Methods: 136 postmenopausal women with urogenital aging symptoms were enrolled in this prospective randomized study. Patients: randomly divided into two groups and each group consisted of 68 women. Interventions: Subjects in the triple therapy (group I) received 1 intravaginal ovule containing 30 mcg estriol and Lactobacilli acidophili (50 mg lyophilisate containing at least 100 million live bacteria) such as once daily for 2 weeks and then two ovules once weekly for a total of 6 months as maintenance therapy plus pelvic floor rehabilitation. Subjects in the group II received one intravaginal estriol ovule (1 mg) plus pelvic floor rehabilitation in a similar regimen. Mean outcome measures: We evaluated urogenital symptomatology, urine cultures, colposcopic findings, urethral cytologic findings, urethral pressure profiles and urethrocystometry before, as well as after 6 months of treatment. Results: after therapy, the symptoms and signs of urogenital atrophy significantly improved in both groups. 45/59 (76.27 %) of the group I and 26/63 (41.27 %) of the group II referred a subjective improvement of their incontinence. In the patients treated by triple therapy with lactobacilli, estriol plus pelvic floor rehabilitation, we observed significant improvements of colposcopic findings, and there were statistically significant increases in mean maximum urethral pressure, in mean urethral closure pressure, as well as in the abdominal pressure transmission ratio to the proximal urethra. Conclusions: our results showed that triple therapy with L. acidophili, estriol plus pelvic floor rehabilitation was effective and should be considered as first-line treatment for symptoms of urogenital aging in postmenopausal women

    Objective: To study the molecular features of mesenchymal stem cells from Wharton Jelly (WJ-MSCs) of umbilical cord to predict their differentiation capacity. Design: Comparison of gene expression from mesenchymal stem cells of male and female umbilical cord Setting: University hospital Patient (s): umbilical cords (n = 12, 6 males and 6 females) retrieved from spontaneous full-term vaginal delivery of healthy women Intervention: we analyzed the expression of the stemness related genes C-MYC, OCT4, SOX2 and NANOG and of the epigenetic modulating gene DNA-methyltransferase 1 (DNMT1). Mean outcome measure: WJ-MSCs were isolated by standard procedures and immunophenotypically characterized. Gene expression analysis of stemness related genes and the epigenetic modulating gene DNMT1 were performed by real-time PCR Results: expression of the OCT4 and DNMT1 genes was significantly higher in WJ- MSCs isolated from male subjects, as compared to MSCs isolated from female-derived WJ. The resulting higher expression of OCT4 and DNMT1 in WJ-MSCs from males as compared with female WJ-MSCs for the first time identifies a specific relationship between stemness genes, an epigenetic modulator, and gender differences. Conclusion: our findings disclose novel biomedical implications in WJ-MSCs related to the sex of the donor, thus providing additional cues to exploit their regenerative potential in allogenic transplantation

    Aim: The aim of this study was to assess the influence of glucose metabolism on the expression of glycosaminoglycans (GAGs) and proteoglycans (PGs) in pregnant women. Material and Methods: Seventy-six women in the first trimester of pregnancy (10–13 weeks) attending the Gynecologic and Obstetric Clinic, University of Sassari, were enrolled and gave early morning urine samples. Groups I, II and III included women with serum glucose values of 65–89 mg/dL, 90–99 mg/dL and 100–125 mg/dL, respectively. Urine GAGs/PGs distribution was determined by electrophoresis on cellulose acetate strips. Urinary N-Acetyl-β-glucosaminidase was estimated kinetically. Results: Analysis of urinary GAGs/PGs electrophoretic profiles showed a significant increase in heparan sulfate (HS) excretion (P = 0.017) as well as a reduced chondroitin sulfate (CS) excretion (P = 0.048) in the group II pregnant women compared with the group I, and higher values of the HS/CS ratio in groups II and III compared to group I. Furthermore, we observed a positive correlation among fasting blood glucose levels and the relative content of HS, the HS/CS and urinary trypsin inhibitor/CS ratios, and the N-Acetyl-β- glucosaminidase levels. Conclusions: The assessment of risk factors for gestational diabetes mellitus should also take into account fasting blood glucose values of 90–99 mg/dL, as the findings of our study indicated an alteration in the metabolism of GAGs during the early stages of pregnancy.</br

    Background: The cellular tumor suppressor protein p16INK4a (p16) has been identified as a biomarker for transforming human papilloma virus (HPV) infections. P16 is a cyclin-dependent kinase inhibitor that regulates the cell cycle and cell proliferation by inhibiting cell cycle G1 progression. Purpose of the study: To confirm the role of p16 as biomarker for transforming HPV infections and possible clinical applications in histological samples from the uterine cervix. Materials and Methods: The subject of this study included 56 biopsies of the cervical canal collected from January 2012 to September 2012 in the Institute of Pathology of the University of Sassari. The search for HPV immunohistochemistry was performed with the monoclonal antibody DAKO 1:25, while for the detection of p16 was used CINtecTM p16 (INK4a) histology kit. Results: In 56 biopsies performed in women aged between 23 and 69 years, the authors highlighted, by histological analysis, 24 cases of low-grade squamous intraepithelial lesion (LSIL) - cervical intraepithelial neoplasia (CIN1) and 31 cases of high-grade squamous intraepithelial lesion (HSIL) - CIN2/3); 15 CIN2, 14 CIN3, and two cervical squamous cell carcinoma in situ (SCIS). One case was an infiltrating squamous cell carcinoma (ISC). In 24 CIN1, there was a 16.67% positivity for p16 and an equal percentage occurred for HPV. In 15 cases of CIN2 the percentage of positivity for p16 was considerably increased (73.33%), unlike the search for HPV which had a positivity rate of 20%. Finally, in 14 cases of CIN3, and in three carcinomas, the positivity for p16 was equal to 100%, however the search for HPV positivity was between 0% and 7.14%. Conclusions: These results demonstrated that p16 was a highly sensitive marker of cervical dysplasia. The authors have shown that p16 overexpression increased with the severity of cytological abnormalities and that had a greater ability to identify the viral infection compared to the classical immunohistochemical staining for HPV

    Partial trisomy of the long arm of chromosome 1: prenatal diagnosis, clinical evaluation and cytogenetic findings: case report and review of the literature

    No full text
    Partial trisomy of the long arm of chromosome 1 is a relatively rare cytogenetic anomaly. Its phenotype has still not been completely defined, because of the cytogenetic heterogeneity of the cases so far described. We report a prenatal case of partial 1q trisomy associated with partial monosomy 4q, secondary to balanced maternal translocation t(1;4). The trisomic segment extended from 1q31.1 to qter and the monosomy 4q was from 4q35.2 to qter. The phenotypic anomalies found by post-mortem and autopsy examinations were compared with those of similar cases reported in the literature. We performed standard cytogenetics and fluorescence in situ hybridization. Cerebral ventriculomegaly, present in our case, seemed to be a constant feature in partial 1q trisomies, so this cerebral malformation could be considered as the main echographic marker for this chromosomal imbalance and trisomy 1q should be added to the list of chromosomal abnormalities associated with ventriculomegaly

    MiRNAs, a small family of non-coding RNA, are now emerging as regulators of stem cell pluripotency, differentiation, and autophagy, thus controlling stem cell behavior. Stem cells are undifferentiated elements capable to acquire specific phenotype under different kind of stimuli, being a main tool for regenerative medicine. Within this context, we have previously shown that stem cells isolated from Wharton jelly multipotent stem cells (WJ-MSCs) exhibit gender differences in the expression of the stemness related gene OCT4 and the epigenetic modulator gene DNA-Methyltransferase (DNMT1). Here, we further analyze this gender difference, evaluating adipogenic and osteogenic differentiation potential, autophagic process, and expression of miR-145, miR-148a, and miR-185 in WJ-MSCs derived from males and females. These miRNAs were selected since they are involved in OCT4 and DNMT1 gene expression, and in stem cell differentiation. Our results indicate a difference in the regulatory circuit involving miR-148a/DNMT1/OCT4 autophagy in male WJ-MSCs as compared to female cells. Moreover, no difference was detected in the expression of the two-differentiation regulating miRNA (miR-145 and miR-185). Taken together, our results highlight a different behavior of WJ-MSCs from males and females, disclosing the chance to better understand cellular processes as autophagy and stemness, usable for future clinical applications

    No full text
    Study Objective: To report our experience with robotic total mesometrial resection (R-TMMR) comparing perioperative results with a series of laparoscopic total mesometrial resections (L-TMMRs). Design: Multicenter retrospective case-control study (Canadian Task Force classification II-2). Setting: Catholic University of the Sacred Heart of Rome (Italy) and Campobasso (Italy). Patients: From July 2013 to August 2015 all cervical cancer patients with preoperative FIGO stage IA2 to IB1 were assessed at preoperative magnetic resonance imaging scan and clinically confirmed by investigation under anesthesia, complying strictly with the FIGO criteria. Surgical and postsurgical data of the TMMR procedures were collected. Interventions: R-TMMR and L-TMMR for early cervical cancer were performed. Measurements and Main Results: Twenty-one women underwent R-TMMR (cases) and 42 patients were submitted to L-TMMR (control subjects) for early cervical cancer. The median estimated blood loss was 150 mL in the cases and 200 mL in the control subjects (p = .992). The median operative time, calculated from the beginning of intraperitoneal procedures to skin closure, was 246 minutes in the cases and 260 minutes in the control subjects (p = .913). The median time to discharge from the hospital was postoperative days 4 (range, 2-5) and 6 (range, 4-15) for R-TMMR and L-TMMR, respectively (p = .001). Conclusion: The few differences we registered do not seem to be clinically relevant, thus making the 2 procedures comparable. Further prospective trials are needed to confirm our results
