RESUMO
Gestational diabetes mellitus (GDM) is a common metabolic disease associated with maternal and foetal complications; gut microbiome might participate in GDM pathogenesis. Possible biological links include short chain fatty acids, incretin hormones, bile acids homeostasis and peroxisome proliferator-activated receptor gamma deficiency. Gut microbiome differs in patients with GDM even in early pregnancy, but no differences are observed five years postpartum. Patients have enriched Verrucomicrobia phylum, Christensenellaceae and Lachnospiraceae families, Haemophilus, Prevotella, Actinomyces, Collinsella and Ruminococcus genera during pregnancy. Clostridiales order, Alistipes, Faecalibacterium, Blautia, Eubacterium and Roseburia genera are depleted. However, there is great heterogeneity in the reviewed studies and scientific data on the use of gut microbiome characteristics and related biomarkers in GDM risk stratification and diagnosis are scarce. Probiotics and synbiotics have been tested for prevention and treatment for GDM with limited efficacy. Future studies should explore the effect of probiotics administration at first trimester of pregnancy and their value as adjuvant therapy.

Results from studies evaluating potential effects of prenatal exposure to radio-frequency electromagnetic fields from cell phones on birth outcomes have been inconsistent. Using data on 55,507 pregnant women and their children from Denmark (1996-2002), the Netherlands (2003-2004), Spain (2003-2008), and South Korea (2006-2011), we explored whether maternal cell-phone use was associated with pregnancy duration and fetal growth. On the basis of self-reported number of cell-phone calls per day, exposure was grouped as none, low (referent), intermediate, or high. We examined pregnancy duration (gestational age at birth, preterm/postterm birth), fetal growth (birth weight ratio, small/large size for gestational age), and birth weight variables (birth weight, low/high birth weight) and meta-analyzed cohort-specific estimates. The intermediate exposure group had a higher risk of giving birth at a lower gestational age (hazard ratio = 1.04, 95% confidence interval: 1.01, 1.07), and exposure-response relationships were found for shorter pregnancy duration (P < 0.001) and preterm birth (P = 0.003). We observed no association with fetal growth or birth weight. Maternal cell-phone use during pregnancy may be associated with shorter pregnancy duration and increased risk of preterm birth, but these results should be interpreted with caution, since they may reflect stress during pregnancy or other residual confounding rather than a direct effect of cell-phone exposure.

Background: The aim of this systematic review is to summarize the evidence regarding the acceptance of uterine transplantation as infertility treatment among gynecological cancer survivors, surgical and pregnancy outcomes post-transplantation for gynecological cancer survivors, as well as relevant adverse events. Methods: PubMed and Embase were searched for records published since 2000, and extensive reference screening was performed. Results: Out of 1901 unique records identified, 7 are included in this review; 4 examined the proportion of gynecological cancer survivors among applicants for uterine transplantation, 2 examined rejection rates, pregnancy rates, and outcomes after uterine transplantation among gynecological cancer survivors, and 2 reported the frequency of relevant adverse events. Among the applicants, 60/701 (8.6%) were gynecological cancer survivors, only 1 transplanted patient was a cervical cancer survivor and achieved two live births after eight embryo transfers, and 2/27 (7.4%) of uterus transplantation recipients were diagnosed with CIN post-transplantation. Conclusions: Uterus transplantation can be regarded as an infertility treatment for absolute uterine factor infertility (AUFI), although only one gynecological cancer survivor has received a uterus transplantation. The efficacy, safety, and ethical considerations for gynecological cancer survivors need to be addressed for uterine transplantation to become an infertility treatment option for AUFI among gynecological cancer survivors.
RESUMO
INTRODUCTION: Egg freezing for social reasons is a process in which women who want to preserve their ability to fertilize their own oocytes at an older age freeze their eggs. With the help of in vitro fertilization, the cryopreservation of oocytes for future use is achieved. The aim of this article is to study the reasons, the risks and the effectiveness of the method from a worldwide aspect. METHODS: A literature search was conducted to evaluate pertinent studies, using data from the search engines PubMed, Google and UptoDate as well as the medical literature. RESULTS: The reasons for delayed procreation are non-medical, with the lack of an appropriate partner for a family being first on the list. The success rate of this method differs with the age of the woman, the number of fertilized eggs and other factors. Like every medical procedure, this method carries risks that relate to the mother (being of advanced age), the embryo and the procedure of in vitro fertilization. The policies that apply in each country differ depending on respective social, economic, religious and cultural factors. Due to the high cost of the method, its selection remains a choice for only a few, reinforcing social inequality. The question of the medicalization of reproduction remains unanswered in the industry of assisted reproduction. CONCLUSIONS: In conclusion, egg freezing for social reasons is gradually becoming more widely known, with the United States of America and Israel being at the top the list. Unfortunately, there is no official data registry, and consequently, no statistical results are yet available for Greece, even though it is a method that more and more women are considering. Nevertheless, there is an imperative need for a universal legal framework for all countries with respect for the needs of every woman and different social conditions. More research and data from the literature are needed in relation to the effectiveness of the method from moral and social perspectives.
RESUMO
Gynecological cancers pose a significant burden on women's health worldwide, necessitating innovative treatment approaches. Immunotherapy has emerged as a promising strategy, harnessing the body's immune system to combat cancer. This review aims to provide a comprehensive overview of the current landscape and future directions of immunotherapy in cervical and endometrial cancer. Methods: A thorough literature search was conducted to identify relevant studies and clinical trials. The main methods and treatments employed in immunotherapy for cervical and endometrial cancer, including immune checkpoint inhibitors, cancer vaccines, and adoptive cell therapies, are briefly described. Results: Immune checkpoint inhibitors, such as anti-PD-1/PD-L1 antibodies, have shown remarkable clinical efficacy in certain gynecological malignancies, particularly in advanced or recurrent cases. Additionally, ongoing research on cancer vaccines and adoptive cell therapies holds promise for personalized and targeted treatment options.
RESUMO
Fibroadenomas are common benign breast tumors. Fibroadenomas that exceed 5 cm in diameter, weigh more than 500 g, or replace more than four-fifths of the breast are characterized as giant. A fibroadenoma diagnosed in patients during childhood or adolescence is characterized as juvenile. An extensive PubMed search of the literature in English up until August 2022 was performed. In addition, a rare case of a gigantic fibroadenoma in an 11-year-old premenarchal girl who was referred to our adolescent gynecology center is presented here. Eighty-seven cases of giant juvenile fibroadenomas have been reported in the literature along with our case. Patients with giant juvenile fibroadenoma presented at a mean age of 13.92 years and usually after menarche. Juvenile fibroadenomas are usually unilateral, occurring either in the right or the left breast; the majority of them are diagnosed when they are already more than 10 cm in size, and they are most frequently treated with total lump excision. Differential diagnosis includes phyllodes tumors and pseudo-angiomatous stromal hyperplasia. Conservative management is feasible, but surgical excision is recommended to patients with suspicious imaging features or when the mass grows rapidly.
RESUMO
Gestational diabetes mellitus (GDM) is a common metabolic disorder among pregnant women. Dietary habits during pregnancy might alter the risk of GDM development, and populations following the Mediterranean diet are relatively understudied. This was a cross-sectional, observational study of 193 low-risk women admitted to a private maternity hospital in Greece to give birth. Food frequency data on specific food categories, selected based on previous research, were analyzed. Logistic regression models, both crude and adjusted for maternal age, body mass index before pregnancy, and gestational weight gain, were fitted. We observed no association of carbohydrate-rich meals, sweets, soft drinks, coffee, rice, pasta, bread and crackers, potatoes, lentils, and juices with GDM diagnosis. Cereals (crude p = 0.045, adjusted p = 0.095) and fruits and vegetables (crude p = 0.07, adjusted p = 0.04) appeared to have a protective effect against GDM, while frequent tea consumption was linked to higher risk of GDM development (crude p = 0.067, adjusted p = 0.035). These results strengthen previously identified associations and underline the importance and potential impact of changing dietary habits even during pregnancy in adjusting one's risk of metabolic pregnancy complications, such as GDM. The importance of healthy dietary habits is highlighted, with the goal of raising awareness amongst obstetric care specialists regarding the provision of systematic nutrition recommendations to pregnant women.
RESUMO
The initiation of puberty is a crucial timepoint of development, with its disruptions being associated with multiple physical and psychological complications. Idiopathic Central Precocious Puberty (iCPP) has been correlated with Single-Nucleotide Polymorphisms (SNPs) of certain genes that are implicated in various steps of the process of pubertal onset. The aim of this review was to gather current knowledge on SNPs of genes associated with iCPP. We searched articles published on the PubMed, EMBASE and Google Scholar platforms and gathered current literature. KISS1, KISS1R, PLCB1, PRKCA, ITPR1, MKRN3, HPG axis genes, NPVF/NPFFR1, DLK1, KCNK9Q, LIN28B, PROK2R, IGF-1, IGF2, IGF-1R, IGF-2R, IGFBP-3, insulin, IRS-1, LEP/LEPR, PPARγ2, TAC3, TACR3, Estrogen receptors, CYP3A4 and CYP19A1 were studied for implication in the development of precocious puberty. SNPs discovered in genes KISS1, KISS1R, PLCB1, MKRN3, NPVF, LIN28B, PROK2R, IRS-1 TAC3, and CYP3A4 were significantly correlated with CPP, triggering or protecting from CPP. Haplotype (TTTA)13 in CYP19A1 was a significant contributor to CPP. Further investigation of the mechanisms implicated in the pathogenesis of CPP is required to broaden the understanding of these genes' roles in CPP and possibly initiate targeted therapies.
RESUMO
The majority of young women will experience discomfort associated with menstrual cycles and miss out on education and social opportunities. Endometriosis, the presence of endometrial glands and stroma outside of uterus, is the most common cause of secondary dysmenorrhea and characterized by pain despite treatment with nonsteroidal anti-inflammatory drugs and hormonal agents. The true prevalence of adolescent endometriosis is not clear. Delay in diagnosis leads to persistent pain, affects quality of life, and potentially contributes to disease progression and subfertility. A laparoscopic diagnosis is the gold standard, but the surgical appearance may differ from adults, as endometriotic lesions are usually red or clear, making their identification a challenge for gynecologists who are unexperienced with endometriosis in adolescents. A personalized medical-surgical treatment is regarded as the most effective therapeutic strategy to achieve remission of symptoms, suppress disease progression, and protect future fertility. Studies have demonstrated how adolescent endometriosis negatively affects patients' quality of life and psychosocial functioning. Development of therapeutic interventions targeting psychosocial function and quality of life is imperative for adolescent patients.
RESUMO
BACKGROUND: Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare congenital syndrome characterized by uterovaginal agenesis. Most patients are diagnosed during adolescence, when body image and sexual identity are shaped. Our main objective was to investigate how MRKH syndrome affects psychology, quality of life (QoL), and the sexual life of patients compared with non-affected individuals. METHODS: Original peer-reviewed research papers examining psychological outcomes, QoL, and sexual function of MRKH patients were searched in PubMed. Titles, abstracts, and full text from potentially eligible records were reviewed by two independent reviewers. Case reports and papers published not in English were excluded. RESULTS: Our search identified 63 records, of which 20 were included: 10 examined psychological and psychosocial outcomes, 14 examined sexual function outcomes, and 6 examined QoL outcomes. Results may be affected by selection bias and confounding due to differences between MRKH patients and controls. CONCLUSIONS: MRKH could be associated with a higher prevalence of anxiety and depression symptoms and social insecurity compared with women of a similar age without the condition. MRKH could also be associated with greater pain and discomfort during sexual intercourse and limitations in arousal, lubrication, and orgasm. MRKH patients more commonly experience impairment of mental-health-related QoL, but physical-health-related QoL is not affected.
RESUMO
Conjoined twins represent a rare type of monoamniotic twins. Ultrasound assessment during the first trimester can facilitate the diagnosis, however further assessment by colour Doppler studies, 3D imaging, fetal echocardiography and fetal magnetic resonance imaging (MRI) is usually required in order to determine the specific fetal abnormalities and to guide appropriate pregnancy management. This case report presents a rare case of conjoined twins complicating a dichorionic-diamniotic triplet pregnancy, achieved after intracytoplasmic sperm injection (ICSI) and blastocyst transfer. A 44-year-old woman was referred for chorionicity determination to our Fetal Medicine Centre due to suspicion of conjoined twins in a triplet pregnancy. Ultrasound assessment at 11 weeks demonstrated a dichorionic triplet pregnancy which was also complicated by a rare type of conjoined twins (thoracoomphalopagus) and after a successful embryo reduction a neonate of 2200 g was delivered by caesarean section at term. The accurate diagnosis and early detection of conjoined twins by a fetal medicine specialist is crucial, especially as far as multiple pregnancies with three or more fetuses are concerned.
RESUMO
Primary spontaneous pneumothorax during pregnancy is a very rare entity. We present a 37-year-old Caucasian woman with spontaneous pneumothorax during the 32nd week of her fourth pregnancy who was treated with intercostal chest drain and was followed up with chest ultrasound. The patient experienced two more episodes of recurrent pneumothorax during pregnancy and puerperium and a uniportal video-assisted thoracoscopic surgery (VATS) was performed. Few such cases have been reported previously in the literature, and there are no relevant medical guidelines. Treatment options include surveillance of a collapsed lung, conservative management with intercostal chest drain, and surgical management with the use of VATS.
RESUMO
Uterine leiomyomas are the most common benign tumor of the female pelvis. Parasitic leiomyomas are an extremely rare entity of leiomyoma occurrence found at extrauterine sites. They are mostly diagnosed in patients with a history of gynecologic procedures and morcellators use during laparoscopic leiomyoma resection. Here we present an extraordinary case of an intraluminal leiomyoma of the sigmoid colon that was incidentally discovered during total abdominal hysterectomy and bilateral salpingo-oophorectomy, performed due to leiomyomatous uterus in a female patient with no history of previous gynecologic operations. Potential pathogenetic mechanisms that can explain the co-occurrence of leiomyomas in the uterus and the sigmoid colon are also reviewed and include genetic predisposition, the stem cell theory of leiomyomas formation, and lymphatic and vascular spread.
RESUMO
Abnormal uterine bleeding (AUB) is a common gynecological complaint in reproductive aged women. In this case report, we present a case of emergency total hysterectomy performed in a hemodynamically unstable patient due to AUB. Based on pelvic ultrasound (US) and CT scan along with the prevalence of uterine smooth muscle tumors, leiomyomatous uterus was the most likely preoperative diagnosis. The histological examination of the surgical specimen revealed a leiomyosarcoma with coagulative necrosis, cellularity, mitotic index greater than 20 mitotic figures per 10 high-power-fields, and local invasion of the myometrium at the tumor's stalk. A positron emission tomography (PET) scan was performed postoperatively. The results revealed multiple hypermetabolic secondary lesions at the lungs bilaterally, liver, vaginal cuff, peritoneal involvement, and a small lesion at the left rectus femoris muscle. Thus, tumor was classified as stage IVB uterine leiomyosarcoma according to the International Federation of Gynecology and Obstetrics (FIGO) staging. The patient was referred to an oncology center for chemotherapy and hormonal therapy. Uterine leiomyosarcomas are the most common uterine sarcomas, but remain a rare entity among uterine smooth muscle tumors. Notably, the US imaging of both leiomyosarcomas and other uterine smooth muscle tumors are practically indistinguishable. Thus, diagnosis is difficult to be established prior to surgical treatment. Overall, prognosis in case of leiomyosarcoma is poor, and tumor stage III/IV, tumor size greater than 10 cm, mitotic index greater than or equal to 20 mitotic figures per 10 high-power-fields, and reactive nuclei for Ki67 more than or equal to 10% are associated with shorter survival period. Reliable risk scores to stratify the risk of malignancy in case of leiomyomatous uterus and guide the timing of surgical treatment are totally lacking, and, thus, hindering earlier diagnosis of leiomyosarcoma and improved prognosis.
