Fertility after "only B-Lynch" suture: A case report and literature review

Abstract Objective A new fertility assessment after a B-Lynch suture without a concomitant uterine devascularization is proposed. Case Report The case of a 37-year-old woman who experienced postpartum hemorrhage due to uterine atony during cesarean delivery of the previous pregnancy is reported. A B-Lynch brace suturing technique, not associated to any other hemostatic surgical procedure, was carried out. One year later and after an uncomplicated pregnancy of 39 weeks, the patient delivered a healthy infant by an elective cesarean section. Only omental adhesions were found on the anterior surface of the uterus as a consequence of the previous B-Lynch suture. Conclusion The B-Lynch hemostatic surgical procedure, alone, does not seem to have a negative impact on fertility. Additional clinical evidences in a greater case-series of patients are needed to assess the value of the method for fertility preservation

The influence of air pollution on the phyllosphere microflora composition of Tillandsia leaves (Bromeliaceae).

The effect of air pollution on total phyllospheric microflora from two species of the epiphytic neo tropical genus Tillandsia (Bromeliaceae) was studied by comparing unpolluted plants living in a forest (Escazú, San José) with polluted ones from an urban site of Costa Rica (San José city). Dilutions of homogenized leaf samples were plated on media suitable for each microbial group. For each microorganism group, total counts were performed and purified strains of randomly chosen colonies were identified. There was a global reduction in the number of living microorganisms due to pollution effects, especially yeasts and bacteria, while nitro gen-fixing microorganisms and fungi were les s affected. Our results showed that the phyllosphere microflora of Tillandsia plants living in a tropical urban environment changes in terms of number and species composition of yeasts and bacteria with respect to plants living in unpolluted environment

Preventing Persistence of HPV Infection with Natural Molecules

Human papillomavirus (HPV) infection is one the most common sexually transmitted infections worldwide. In most cases, the infection is temporary and asymptomatic; however, when persistent, it may lead to lesions that can evolve into cancer in both women and men. Nowadays, prophylactic vaccination is the primary preventive strategy for HPV infections, but vaccines do not cover all types of HPV strains. Scientific research has uncovered the beneficial role of some natural supplements in preventing persistent HPV infections or treating HPV-related lesions. We review the current insight into the roles of natural molecules in HPV infection with a special focus on epigallocatechin gallate (EGCG), folic acid, vitamin B12, and hyaluronic acid (HA). Specifically, EGCG from green tea extracts plays a critical role in suppressing HPV oncogenes and oncoproteins (E6/E7), which are responsible for HPV oncogenic activity and cancer development. Folic acid and vitamin B12 are essential vitamins for multiple functions in the body, and accumulating evidence suggests their importance in maintaining a high degree of methylation of the HPV genome, thus decreasing the likelihood of causing malignant lesions. HA, due to its re-epithelizing property, may prevent HPV virus entry in damaged mucosa and epithelia. Thereby, based on these premises, the combination of EGCG, folic acid, vitamin B12, and HA may be a very promising therapeutic approach to prevent HPV persistence

The challenge of FIGO type 3 leiomyomas and infertility: Exploring therapeutic alternatives amidst limited scientific certainties

Uterine leiomyomas (ULs) are non-cancerous tumors composed of smooth muscle cells that develop within the myometrium and represent the most prevalent pathological condition affecting the female genital tract. Despite the volume of available research, many aspects of ULs remain unresolved, making it a "paradoxical disease" where the increase in available scientific literature has not been matched by an increase in solid evidence for clinical management. Fertility stands at the top of the list of clinical issues where the role of ULs is still unclear. The leiomyoma subclassification system, released by the International Federaion of Gynecology and Obstetrics (FIGO) in 2008, introduced a new and more effective way of categorizing uterine fibroids. The aim was to go beyond the traditional classification "subserosal, intramural and submucosal", facilitating a detailed examination of individual ULs impact on the female reproductive system. The "type 3 UL" is a special type of myoma, characterized by its complete myometrial development while encroaching the endometrium. It is a unique "hybrid" between a submucous and an intramural UL, that may exert a detrimental "double hit" mechanism, which is of particular interest in patients wishing pregnancy. To date, no robust evidence is available regarding the management of type 3 ULs. The aim of this narrative review is to provide a comprehensive overview of the physiopathological mechanisms that type 3 UL may exert on fertility, and to present new perspectives that may help us to better understand both the need for and the methods of treating this unique type of fibroid

Feasibility and Surgical Outcomes of Hysteroscopic Myomectomy of FIGO Type 3 Myoma: A Systematic Review

The latest classification from the Fédération Internationale de Gynécologie et d'Obstétrique (FIGO) has reclassified type 3 myomas, changing their classification from intramural to submucosal. While hysteroscopic myomectomy is considered the gold standard treatment for patients experiencing symptoms from submucosal myomas, there are currently no specific guidelines available for managing type 3 myomas, and the optimal surgical approach remains uncertain. Methods: The search for suitable articles published in English was carried out using the following databases (PROSPERO ID CRD42023418602): MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Cochrane Methodology Register), Health Technology Assessment Database, Web of Science and search register. Only original studies reporting data on hysteroscopic myomectomy of type 3 myoma were considered eligible. The main outcomes investigated were the effectiveness and feasibility of hysteroscopic myomectomy and reproductive outcomes after surgical treatment. Results: Two hundred and sixty-one studies were screened and nineteen of these were read for eligibility. Three studies encompassing 56 patients in total were included. Among the overall population studied, three patients needed an additional procedure to completely remove the myoma and five cases of post-surgical synechiae were recorded. No complications were reported. Of 42 patients wishing for pregnancy, the cumulative live birth rates before and after the hysteroscopic myomectomy were 14.3% and 42.9%, respectively. Conclusions: Hysteroscopic myomectomy appears to be a safe and feasible approach. Nevertheless, data reported in the literature are extremely scarce and based on studies with few patients enrolled. New evidence is needed to assess the safety and effectiveness of hysteroscopic treatment for FIGO type 3 myomas

COVID-19 and Pregnancy: An Updated Review about Evidence-Based Therapeutic Strategies

The COVID-19 pandemic posed a significant challenge for clinicians in managing pregnant women, who were at high risk of virus transmission and severe illness. While the WHO declared in May 2023 that COVID-19 is no longer a public health emergency, it emphasized that it remains a global health threat. Despite the success of vaccines, the possibility of new pandemic waves due to viral mutations should be considered. Ongoing assessment of the safety and effectiveness of pharmacological therapies is crucial in clinical practice. This narrative review summarizes the evidence-based therapeutic strategies for pregnant women with COVID-19, considering over three years of pandemic experience. The review discusses the safety and effectiveness of various drug regimens (antivirals, anticoagulants, corticosteroids, immunoglobulins, monoclonal antibodies, and therapeutic gases) and procedures (prone positioning and extracorporeal membrane oxygenation). Drugs with contraindications, inefficacy during pregnancy, or unknown adverse effects were excluded from our evaluation. The aim is to provide healthcare professionals with a comprehensive guide for managing pregnant women with COVID-19 based on lessons learned from the pandemic outbreak

I diritti umani nella Cooperazione allo sviluppo: il caso della Convenzione di Lomé (1975-1995)

La presente tesi mira a comprendere il ruolo giocato dalla discussione relativa all'inserimento dei diritti umani nella Convenzione di Lomé, un accordo di cooperazione allo sviluppo tra la CEE ed il gruppo ACP (Africa, Caraibi e Pacifico). Questa discussione influenzò profondamente l'evoluzione della Convenzione da accordo particolarmente innovativo nel campo della cooperazione allo sviluppo ad accordo squilibrato tra le due parti con una forte condizionalità degli aiuti economici. L'inserimento dei diritti umani nella Convenzione trovò forte opposizione dagli ACP, venendo escluso da Lomé II, prima di essere accolto in Lomé III e IV, diventando così il primo accordo di cooperazione allo sviluppo a includere considerazioni relative ai diritti umani. Questo processo si è accompagnato al progressivo arricchimento del concetto di sviluppo, che acquisì progressivamente nuove dimensioni non esclusivamente economiche. Questo processo viene analizzato con un'attenta ricerca storiografica sull'evoluzione delle quattro Convenzioni di Lomé, e della progressiva avanzata del tema dei diritti umani al suo interno, in un campo pressoché inesplorato dalla storiografia. My research aims to investigate the role of human rights in shaping concepts, contents and practices of EC’s development cooperation relations with developing countries. More specifically, I intend to determine whether and to what extent did the insertion of human rights in the theoretical framework underlaying the very concept of development affect relations between the EC and a substantial group of developing countries, the ACP. This interrelation was embodied by the Lomé Convention, a large agreement that established an equal partnership between ACP and EC, signed in 1975 and renewed in 1979, 1984, 1989 and 1995. The Lomé relationship, which represents the most durable and innovative North-South cooperative agreement, underwent radical changes in both theory and practice, turning from model of an equitable industrial/developing countries relationship to an asymmetric one in which the EC, as donor, could attach economic and political conditions to the granting of aid to the ACP. These changes were the result of the growing interrelation between development and human rights, embodied in the progressive insertion of the latter in the Convention

Likelihood of Accomplishing an In-Patient Hysteroscopic Myomectomy in a One-Step Procedure: A Systematic Review and Meta-Analysis

Purpose. To assess the feasibility rate of one-step hysteroscopic myomectomy according to the technique adopted. Methods. In July 2016, PubMed, ClinicalTrials.gov, SCOPUS, Scielo, and AJOL databases were used for searching references. Series of in-patient hysteroscopic myomectomies reporting success rate in only one-step procedure, categorization of submucous fibroids, explanation of the surgical technique, and description of patients were considered eligible for meta-analysis (retrospective, prospective randomized studies). Two authors extracted the data. Rate of myomectomies accomplished in only a surgical step and rate of intraoperative complications were extracted per protocol. A modified GRADE score was used for quality assessment. Random-effect models were already assumed. Mean rates were compared among subgroups. Results. One thousand two hundred and fifty-seven studies were screened and 241 of these were read for eligibility. Seventy-eight series were included in qualitative synthesis and 24 series were included in quantitative synthesis. Wide heterogeneity was found. In series with <50% of G2 myomas treated, the slicing technique feasibility rate was 86.5% while techniques for enucleating the deep portion of the myomas showed a feasibility rate of 92.3% (p<0.001). In series with ≥50% of G2 myomas treated, the slicing technique feasibility rate was 70.6% while techniques for enucleating the deep portion of myomas showed a feasibility rate of 88.4% (p<0.001). Complications were significantly lower for alternative techniques to the classical slicing. Conclusion. In case of submucous myomas with intramural development, the slicing technique was correlated with a lower rate of in-patient hysteroscopic myomectomies accomplished in a one-step procedure and a higher complications rate

Effectiveness and Safety of Posterior Vaginal Repair with Single-Incision, Ultralightweight, Monofilament Propylene Mesh: First Evidence from a Case Series with Short-Term Results

Objective. The use of transvaginal mesh is controversial, and over time, multiple surgical methods for the treatment of posterior vaginal prolapse (PVP) have been proposed including different surgical approaches and techniques. To date, no clear conclusion has been reached about the use of mesh for reinforcing transvaginal posterior repair. The aim of this study was to evaluate the feasibility, safety, and effectiveness of a novel, ultralightweight mesh for the treatment of PVP. Methods. We performed a single-center, prospective observational study on consecutive patients referred for primary or recurrent, symptomatic stage II PVP (according to the international Pelvic Organ Prolapse Quantification System) from April 2017 to September 2018. In all patients, transvaginal posterior repair was augmented with a single-incision, isoelastic polypropylene mesh. Data about the postoperative outcomes were collected until December 2019. Results. A total number of 15 patients were included. The median follow-up after surgery was 18 months (IQR=14). Surgery was completed in all cases without complications. Regarding the anatomical outcomes (as measured according to POP-q classification), a significant improvement was observed in terms of Bp, D, and C (p<0.05). The functional outcomes were significantly ameliorated after surgery, with a reduction of bulge symptom, stypsis, incomplete evacuation, and excessive staining (p<0.05). The quality of life was significantly improved in the majority of patients (p<0.05). Median patients' satisfaction rate was 100% (IQR=22.5%). Neither early nor late postoperative complications occurred. Conclusions. Single-incision, ultralightweight polypropylene meshes were safe and highly effective in the treatment of PVP. As our study has some limitations, further large, controlled studies are needed
