A large multicenter propensity match study of sentinel lymph node biopsy feasibility in endometrioid variants of endometrial cancer
2022
Introduction: Sentinel lymph node (SLN) biopsy algorithm has been routinely applied in all endometrial endometrioid tumors, however, no studies analyzed the feasibility of SLN mapping in endometrioid variants (EV), which included villoglandular, secretory, ciliated cell, mucinous, and squamous differentiation. This study aimed to demonstrate the feasibility of SLN biopsy in EV of EC. Materials and methods: All patients undergoing minimally invasive surgical treatment for early-stage EC were included in the study. Patients were divided into 2 study groups: Group 1 which included patients with EV, and Group 2 which included patients with typical endometrioid histology. A propensity match anal…
Headspace Volatile Composition of the Flowers of Caralluma europaea N.E.Br. (Apocynaceae)
2009
The volatile constituents of the flowers of Caralluma (Apteranthes) europaea (Guss.) N.E. Br. (Apocynaceae - Asclepiadoideae) from Lampedusa Island were analyzed by headspace method. The analyses allowed the identification and quantification of 41 compounds. The main components were, among the monoterpenoids, terpinolene (23.3%), a-terpinene (19.1%) and linalool (18.4%), whereas, among the carbonylic compounds the major constituents were heptanal (2.0%), octanoic acid (2.4%) and hexanoic acid (1.7%). It is worth to mention the presence of a nitrogen containing compound, indole (0.8%) and of a sulphur containing compound, dimethylsulphide (t). The compounds found in the flowers of C. europea…
First helminthological data on the Iberian adder, Vipera seoanei.
2023
Abstract Helminth fauna and some biotic and abiotic traits were analysed in Iberian adder Vipera seoanei (Squamata: Viperidae) a European viper nearly endemic to northern Iberian Peninsula, in an attempt to confirm previous claims of relationships between this ecological traits in this genus. A total of 317 samples mostly covering the distributional range of V. seoanei, were examined. Compared with other Vipera species from the Iberian Peninsula, the helminth fauna is also impoverished in V. seoanei, but it is contrary to other Vipera species from Central and East Europe. Helminths were mostly found in adult vipers, and occurred in vipers located at the periphery of the species range, chara…
Cervical cancer and intraepithelial neoplasia
2012
Cervical cancer is the second most frequent malignancy in women. Infection with high-risk papillomaviruses causes cervical cancer and can be prevented by vaccination. Secondary prevention using cytology and/or human papillomavirus testing successfully decreases the incidence of cancer by detection of cervical intraepithelial neoplasia (CIN). Colposcopy is used to locate CIN and to assure preservation of healthy tissue when removing CIN. Diagnosis of CIN and cancer is based on histopathology. In invasive disease, imaging techniques such as MRI or PET-CT help to assess the locoregional extent of the disease. For staging, the FIGO and TNM system are applied. Laparoscopic staging, especially of…
Myomectomy in infertile women: More harm than good?
2023
Adhesion formation following gynecological surgery remains a challenge. The adoption of minimally invasive surgical approaches, such as conventional or robotic-assisted laparoscopy combined with meticulous microsurgical principles and the application of adhesion–reducing substances, is able to reduce the risk of de novo adhesion formation but do not eliminate it entirely. Myomectomy is the most adhesiogenic surgical procedure and postoperative adhesions can have a significant impact on the ability to conceive. Therefore, when surgery is performed as infertility treatment, attention should be paid to whether the benefits outweigh the risks. Among several factors, the size and the location of…
Human papillomavirus infection in couples undergoing in vitro fertilization procedures: impact on reproductive outcomes.
2011
A prospective study was performed to assess the relationship between human papillomavirus (HPV) infection in 199 infertile couples and outcome of assisted reproductive technologies (ARTs). A highly statistically significant correlation between pregnancy loss rate (proportion of pregnancies detected by β-hCG that did not progress beyond 20 weeks) and positive HPV DNA testing in the male partner of infertile couples, compared with HPV negatives, was observed (66.7% vs. 15%).
Management of Infertility: A Practical Approach
2022
Management of Infertility: A Practical Approach offers an accurate and complete reference for the management of infertility and a robust step-by-step guide for assisted reproduction technologies (ARTs), including how to plan, design and organize a clinical setting and laboratory. The book also provides an evidence-based, complete and practical description of the available methods for diagnosis and management of male and female infertility. This will be an ideal resource for researchers, students and clinicians who want to gain complete knowledge about both basic and advanced information surrounding the diagnosis and management of infertility and related disorders.
PCOS and infertility. Metformin administration and ovulation induction in patients with reproductive failures. Preliminary data
2014
The aim of this study is to investigate the effects of the metformin administration in patients with previous reproductive failures. Inclusion criteria: 13 patients with chronic anovulation and PCOS, age < 38 years old, sterility not less than 2 years, C.C. resistance, conception failure in previous cycles with only r-FSH and negativity to the multiple miscarriages tests, absence of others infertility factors. Metformin administration started 2 months before the ovulation induction. Alternatively a spontaneous menstruation it was induced by progestin. Ovulation was performed with r-FSH and patients were invited to have sexual intercourse during the 48h after the HCG trigger. Luteal support …
Uterine cervical stenosis: from classification to advances in management. Overcoming the obstacles to access the uterine cavity
2023
Background: To date hysteroscopy is the gold standard technique for the evaluation and management of intrauterine pathologies. The cervical canal represents the access route to the uterine cavity. The presence of cervical stenosis often makes entry into the uterine cavity difficult and occasionally impossible. Cervical stenosis has a multifactorial etiology. It is the result of adhesion processes that can lead to the narrowing or total obliteration of the cervical canal. Purpose: In this review, we summarize the scientific evidence about cervical stenosis, aiming to identify the best strategy to overcome this challenging condition. Methods: The literature review followed the scale for the q…
La valutazione ambientale delle strategie urbane di sviluppo: nuovi modelli per l'integrazione ambientale delle scelte in ambito urbanistico
2017
La valutazione ambientale strategica è, prima di essere codificata nelle forme della VAS, una possibile declinazione della pianificazione strategica che nelle tematiche ambientali della sostenibilità e, potenzialmente, nei paradigmi dell’ecological urbanism o del re-cycle un nuovo modo di lavorare al progetto urbanistico. Il paper descrive le attività svolte in tal senso dal Dipartimento Regionale dell’Urbanistica (DRU) della Regione Siciliana con la collaborazione scientifica di chi scrive, al fine di ripensare la VAS come un modello di progettazione della trasformazione urbana anziché come un accessorio a posteriori del Piano. L’emanazione della Direttiva 1/2015 DRU/VAS e le conseguenti a…
