Background
We investigated the impact of pulmonary recruitment maneuver in reducing shoulder pain after laparoscopic procedure.
Methods
We conducted a systematic review of the literature using Medline (1966–2014), Scopus (2004–2014), Popline (1974–2014),
www.ClinicalTrials.gov
(2008–2014), and Google Scholar (2004–2014) along with reference lists of electronically retrieved studies. Statistical meta-analysis was performed using the RevMan 5.1 software.
Results
Six studies were included in the present systematic review, involving 571 patients. Among them, 291 (51 %) were offered a pulmonary recruitment maneuver, and 280 patients (49 %) were treated with conventional evacuation of pneumoperitoneum that included either passive evacuation or gentle pressing of the abdominal walls with the trocar ports open. The introduction of a pulmonary recruitment maneuver significantly decreased postoperative shoulder pain 12 h (435 patients, REM, MD −1.55, 95 % CI −2.01, −1.10), 24 h (435 patients, REM, MD −1.59, 95 % CI −2.00, −1.18), and 48 h post-operatively (335 patients, REM, MD −0.93, 95 % CI −1.37, −0.50). We also identified evidence of a potential beneficial effect in the reduction of postoperative upper abdominal pain. However, discrepancies in the interpretation of abdominal pain among the included studies precluded meta-analysis of this index.
Conclusions
According to the results of our meta-analysis, pulmonary recruitment maneuver seems to be an easily performed, potentially preventive measure of post-laparoscopic shoulder pain. Further research is mandated, however, in the field, because firm results are precluded by the small number of included studies.

Botulinum toxin for the prevention and healing of wound scars: A systematic review of the literature
2015
Background
Botulinum toxin injections have been investigated for the treatment or prevention of hypertrophic scars in several clinical studies. However, its clinical effectiveness has not yet been established.
Objective
To examine all available evidence that support the use of botulinum toxin injections for the treatment or prevention of hypertrophic scars in current clinical practice.
Methods
A systematic review searching the MEDLINE (1966 to 2014), Scopus (2004 to 2014), Popline (1974 to 2014), ClinicalTrials.gov (2008 to 2014) and Cochrane Central Register of Controlled Trials (CENTRAL) (1999 to 2014) databases together with reference lists from included studies was conducted.
Results
Te n studies (255 patients) were included. Of these, 123 patients were injected with botulinum toxin type A, nine patients were offered botulinum toxin type B and the remaining 123 patients represented the control groups. Significantly improved cosmetic outcomes were observed among certain studies using the visual analogue scale (experimental group: median score 8.25 [range 6 to 10]) versus control group: median score 6.38 [range 2 to 9]; P<0.001) and the Stony Brook Scar Evaluation Scale (experimental group score: 6.7 versus control group score: 4.17; P<0.001) assessments. However, the methodological heterogeneity of the included studies, the lack of control group in the majority of them, the use of subjective scales of measurement and the frequent use of patient self-assessment precluded unbiased results.
Conclusions
Current evidence does not support the usage of botulinum toxin. Future randomized controlled trials are needed in the field to reach firm conclusions regarding its place in current clinical practice.

Mucosal melanomas exhibit discrete genetic features compared to cutaneous melanoma. Limited studies on gynecological melanomas revealed significant heterogeneity and low mutational burden. To gain further insight into their genetics and DNA repair efficiency, we systematically investigated the status of eight genes whose products are critically involved in the MAPK/ERK, PI3K/AKT, and GNAQ/11 pathways, including BRAF, NRAS, HRAS, KRAS, c-KIT, PI3K, GNAQ, and GNA11, in a series of 16 primary gynecological melanomas, covering all anatomical locations, ranging from stages I to III. Analysis either by real-time PCR coupled with fluorescence melting curve analysis or by PCR followed by direct sequencing, along with studies for DNA mismatch repair status using immunohistochemistry, disclosed that 15 out of the 16 cases displayed wild-type genotypes, with a single case of vulvar primary melanoma, harboring the activating mutation BRAFV600E. Investigations on whether this could reflect partly an efficient mismatch repair (MMR) mechanism were confirmed by normal expression of hMLH1 and hMSH2, suggesting that the lack of mutations could be explained by the operation of alternative pathogenetic mechanisms modulating downstream effectors of the signaling pathways. Our data suggest the presence of additional genetic components and provide the impetus for systematic approaches to reveal these yet unidentified genetic parameters.

We report a rare case of a large prolapsed pedunculated uterine myoma measuring 15 cm in its greater diameter. In order to make a surgical procedure safe and feasible, appropriate clinical predictors should be taken into account and pre‐ and intraoperative preparations be available to the surgeon's armamentarium.

In-hospital patients who are in the gynecologic oncology setting often suffer from malnutrition, which is one of the primary problems, the rate of which reportedly ranges from 28% to 70%. Malnutrition is a significant risk factor for immunosuppression, negatively impacting immune response and postoperative recovery capacity. At the time of the surgeries, due to their wide scope and aggressive treatments such as chemotherapy and radiotherapy, the situation becomes more serious. Those micronutrients taking part in immunonutrition, namely, arginine, omega-3 fatty acids, nucleotides, and antioxidants, have the potential to prevent inflammation, protect against infections, and promote healing after the surgery. Research has shown that immunonutrition can lower the risk of postoperative infection, promote the normal healing of wounds, and reduce the hospital stays of patients, as well as support malnutrition status during chemotherapy. This review is based on a literature search conducted in Medline, Scopus, Clinicaltrials.gov, Cochrane CENTRAL, and Google Scholar, with the last search date being November 2024. Some studies. found that perioperative immunonutrition decreases wound infections and affects some immune indexes in gynecologic oncology patients positively. However, factors such as non-compliant patients, high costs, and non-standard formulations can deter its wider use. Patient adherence drops postoperatively mainly due to nausea and decreased appetite, whereas the cost of enriched formulations acts as an economic barrier. Postoperative compliance drops from ~78% prior to surgery to ~28% due to nausea, anorexia, and chemotherapy. Additionally, cost remains a constraining factor since special formulas are 2–4 times that of normal nutrition. While immunonutrition reduces hospital stay (by ~2–3 days) and infection rate (by 25–40%), access is hindered by prohibitive initial costs and lack of insurance coverage. Approaches such as subsidized schemes, enhanced palatability, and cost–benefit analyses are required to increase adoption. In addition, the lack of standardized protocols makes the clinical community hesitant to adopt this approach. Immunonutrition is, despite these problems, still hoped to be the new adjunct to gynecologic oncology patients. In future studies, it is imperative to pay attention to the best formulations that produce the best outcomes and evaluate and implement guidelines that are based on evidence. Together, with these improvements, immunonutrition could very well be an integral part of perioperative care thus completing the process by which patients in intense treatments are benefited not only via treatment but also via quality of life.

Background: Assessing fetal growth constitutes a fundamental aim within the realm of prenatal care. Impaired prenatal growth increases the risk of perinatal mortality, morbidity, and poor newborn outcomes. Growth restriction increases the risk of premature birth problems, as well as the risk of poor neurodevelopmental outcomes and future non-communicable disorders such as hypertension and metabolic syndrome as adults. The objective of this systematic review is to accumulate current literature evidence to assess the patterns of serum adipokine levels among women with growth-restricted fetuses and assess their potential alterations in those high-risk pregnancies. Methods: Medline, Scopus, CENTRAL, Clinicaltrials.gov, and Google Scholar databases were systematically searched from inception until 31 March 2023. All observational studies reporting serum adipokine values among women with appropriately grown and growth-restricted fetuses were held eligible. Results: The current systematic review encompassed a total of 20 studies, incorporating a patient population of 1850 individuals. Maternal blood leptin emerged as the adipokine most investigated, as evidenced by 13 studies encompassing a collective sample size of 1081 patients, all of which explored its potential correlation with intrauterine growth restriction. Elevated levels of leptin were detected in fetuses with intrauterine growth restriction, although the observed difference did not reach statistical significance. Furthermore, regarding adiponectin, the meta-analysis conducted indicated that there were not any statistically significant differences observed in the mean values of adiponectin. The available data on the remaining three adipokines were extremely limited, making it difficult for any solid conclusions to be extracted. Conclusions: Though limited and inconsistent, the existing data suggest that fetal growth restriction is not linked to leptin, adiponectin, visfatin, resistin, or RBP4. More substantial prospective studies are needed to comprehend the importance of established and novel adipokines.

Clinician attitude towards sexual counseling in women with gynecologic malignancies: European Network of Young Gynaecological Oncologists (ENYGO) survey
2022
Both the location of primary disease and treatment side effects may have an impact on sexual function in oncogynecological patients. The aim of this study was to examine the prevalence, strategies, difficulties, and ideas for improvement in sexual counseling among specialists managing patients with gynecologic malignancies.
This was a cross-sectional survey study performed among healthcare professionals treating patients with gynecologic malignancies. A self-prepared questionnaire included 61 questions concerning general demographic information and different aspects of sexual counseling in the gynecologic oncology practice. Analysis included attitudes, behaviors, management strategies, difficulties, and ideas for possible systemic improvements. Statistical analysis involved descriptive statistics, two-sided chi-square test, and Fisher’s exact test.
A total of 150 respondents from 46 countries answered the survey. The majority of survey participants stated that sexual counseling of oncological patients is very important (n=73, 49%) or important (n=46, 31%). One hundred and two (68%) respondents agreed that sexual counseling of gynecologic oncology patients should be routinely provided by the specialist managing the primary disease. However, collecting information concerning sexual function is performed often or always by only 21% of respondents and 19% discuss the topic rarely or never. The most frequently indicated barriers leading to difficulties in sexual counseling include lack of time (74%), lack of specialist knowledge (55%), and patient embarrassment (48%). One hundred and seven (71%) respondents expressed interest in participating in sexual counseling workshops organized by the European Society of Gynaecological Oncology (ESGO)/European Network of Young Gynaecological Oncologists (ENYGO), 74 (49%) would like to access webinars on the topic, and 120 (80%) would be interested in materials in the ESGO online educational resources.
One of the proposed solutions to insufficient access to sexual care for women with gynecologic malignancies is providing access to specialist educational programs for both patients and healthcare specialists.

BackgroundESGO (European Society of Gynaecological Oncology) and partners are continually improving the developmental opportunities for gynaecological oncology fellows. The objectives of this survey were to evaluate the progress in the infrastructure of the training systems in Europe over the past decade. We also evaluated training and assessment techniques, the perceived relevance of ENYGO (European Network of Young Gynaecological Oncologists) initiatives, and unmet needs of trainees.MethodologyNational representatives of ENYGO from 39 countries were contacted with an electronic survey. A graduation in well/moderately/loosely-structured training systems was performed. Descriptive statistical analysis and frequency tables, as well as two-sided Fisher’s exact test, were used.ResultsNational representatives from 33 countries answered our survey questionnaire, yielding a response rate of 85%. A national fellowship is offered in 22 countries (66.7%). A logbook to document progress during training is mandatory in 24 (72.7%) countries. A logbook of experience is only utilized in a minority of nations (18%) for assessment purposes. In 42.4% of countries, objective assessments are recognized. Trainees in most countries (22 (66.7%)) requested additional training in advanced laparoscopic surgery. 13 (39.4%) countries have a loosely-structured training system, 11 (33.3%) a moderately-structured training system, and 9 (27.3%) a well-structured training system.ConclusionSince the last publication in 2011, ENYGO was able to implement new activities, workshops, and online education to support training of gynaecological oncology fellows, which were all rated by the respondents as highly useful. This survey also reveals the limitations in establishing more accredited centers, centralized cancer care, and the lack of laparoscopic training.
