Abstract
Primitive neuroectodermal tumor (PNET) is a general term used in scientific literature for a heterogeneous group of small round-cell malignant tumors primarily arising from neural crest cells. These are extremely aggressive neoplasms which usually occur within soft tissue or bone of young adults. Ovarian tumors composed of primitive neuroectodermal elements are extremely rare, with only few case reports in scientific literature. Due to being so exceedingly rare, PNETs are frequently misdiagnosed and there are no standard therapeutic guidelines. Young patients seem to have better prognoses and individualized strategy is recommended. Limited data suggests that various gene deletions as well as amplifications may be crucial factors for tumorigenesis and the aggressive behavior of PNET. In this paper, we performed a brief review of all cases of primary ovarian PNETs published in the scientific literature to date, in regard to their clinical, histopathological, and therapeutic aspects, with the aim to provide a more comprehensive understanding of this exceedingly rare pathology.

Abstract
This study provides a conceptual exploration of an innovative telemedicine-enhanced team-based care (TETC) model, tailored to prenatal care, integrating a multidisciplinary team approach with advanced telemedicine technologies. The algorithm developed for TETC aims to optimize communication and coordination among healthcare professionals, including obstetricians, midwives, nutritionists, and mental health experts. This cohesive team structure ensures a comprehensive care plan encompassing all facets of maternal and fetal health. Leveraging telemedicine tools like video conferencing and digital health records, the model supports remote consultations and coordinated care, proving particularly advantageous during pandemics or in regions with limited healthcare access. Central to the TETC model is patient-centered care, focusing on personalized care plans attuned to the individual needs, health status, and socioeconomic backgrounds of pregnant women. This approach not only enhances accessibility and convenience by diminishing the necessity for physical consultations but also ensures continuity of care throughout pregnancy. This continuity is crucial for consistent health parameter tracking and early risk identification. The paper discusses the model's design, operational workflow, and ethical and legal considerations, providing implementation guidelines and potential applications. The TETC model, rooted in current technological capabilities and healthcare frameworks, underscores the need for close collaboration with healthcare professionals to adhere to medical standards and address real-world requirements effectively.

Abstract
During pregnancy, hormonal and immune adaptations are vital for supporting the genetically distinct fetus during elevated infection risks. The global prevalence of HPV necessitates its consideration during pregnancy. Despite a seemingly mild immune response, historical gestational viral infections underscore its significance. Acknowledging the established HPV infection risks during pregnancy, our review explores the unfolding immunological changes in pregnant women with HPV. Our analysis aims to uncover strategies for safely modulating the immune system, mitigating adverse pregnancy consequences, and enhancing maternal and child health. This comprehensive narrative review delves into the existing knowledge and studies on this topic.

Abstract
Acute promyelocytic leukemia (APL) is generated by the PML-RARA fusion gene. In patients suffering from APL, the early diagnosis and treatment are essential in the successful management. We reported a case of a 27-year-old 17th-week pregnant patient diagnosed with APL. After an extensive hematological diagnostic panel, the acute promyelocytic leukemia was confirmed, and the patient received all-trans retinoic acid (ATRA), idarubicin (IDA), and dexamethasone, following national guidelines. Due to ATRA-related differentiation syndrome, the therapy was adjusted, and hydroxycarbamide was added with a good outcome. The patient was admitted to the ICU secondary to hypoxemic respiratory failure on the 2nd day after hospital admission. Our patient received an individualized drug combination, adjusted by the clinical response. Furthermore, the drugs used in APL treatment are all teratogenic. Despite various major complications, including severe acute respiratory distress syndrome (ARDS), which needed mechanical ventilation; ICU-acquired myopathy; and spontaneous abortion, the patient had a good outcome and was transferred from the ICU after a total stay of 40 days. APL during pregnancy is a rare entity of intermediate-risk APL. Our study emphasized the need for individualized therapy in a rare case of a pregnant woman diagnosed with a potentially fatal hematologic disease.

Abstract
Objective. We aim to evaluate the implications of cesarean delivery compared to natural birth by analyzing newborns’ systemic and cerebral oxygenation levels during the first 10 minutes of life. Design. This paper presents a 4-year prospective cohort study. Setting. Polizu Maternity, "Alessandrescu-Rusescu" National Institute for Mother and Child's Protection, Bucharest, Romania. Patients. Randomly selected pregnant women and their fetuses. Interventions. During the 10 min following umbilical cord clamping, regional cerebral oxygen saturation (rcSO2) was measured using the INVOS 5100 device and peripheral oxygen saturation (SpO2) was determined using the Masimo SET pulse oximeter in neonates from cesarean and natural deliveries. Main outcome measures. The cerebral fractional tissue oxygen extraction (cFTOE) in the first 10 minutes of life was calculated based on these values. Results. Newborns delivered vaginally showed higher rcSO2 levels at 1 minute of life than those born via C-section (40.5 ± 16.5% vs 33.7 ± 14.8%, AUC = 0.625; IC 95%: 0.506 - 0.743; p = 0.043). Neonatal cFTOE at 1 minute of life was significantly higher in caesarean-delivered newborns versus naturally born neonates (0.40 ± 0.25 vs 0.50 ± 0.19, p = 0.03; AUC = 0.638; IC 95%: 0.517-0.758; p = 0.023). Conclusions. Prelabor cesarean delivery seemingly plays a significant role in the process of fetal and neonatal cerebral oxygenation immediately postnatally, which is highlighted by lower rcSO2 and higher cFTOE values. Cerebral oxygen saturation monitoring in the delivery room allows the optimization of oxygen therapy in order to prevent the consequences of hypoxia or hyperoxia.

Abstract
Background. Clear cell carcinoma of the ovary developing in the background of an ovarian teratoma represents an extremely rare entity of the gynecologic tract. Giving the rarity of this entity, the histologic challenges, prognosis and the adequate treatment is still uncertain. Methods. We herein present a case of clear cell carcinoma coexisting with a teratoma, accompanied by a scrutinous literature review. The authors have reviewed all case reports published in the literature (1978-2021), adding our new case, in order to enrich current literature data. Results. A thorough search of the PubMed/MEDLINE and Google Scholar databases has revealed 7 cases of clear cell carcinoma of the ovary developing in association with a teratoma. Out of the 7 cases, 4 were part of a more complex tumor, including other malignancies (e.g. angiosarcoma, endometrioid carcinoma). The mean size of the tumors was 16 cm and most patients died of disease or suffered multiple recurrences. Additionally, we report a case of a 54-year-old patient who presented with an ovarian tumor and which upon microscopic examination featured a cystic structure lined by squamous keratinizing epithelium and sebaceous glands. Inside the wall of the cyst, a small nodule made out of tubules and papillae lined by clear cells, which invaded the surrounding stroma was identified. Four months later, the patient developed a small nodule in the liver and she has subsequently received adjuvant chemotherapy. Conclusion. Clear cell carcinoma of the ovary developing in association with a teratoma is an extremely rare entity, that requires thorough sampling of the cyst and which is usually associated with a relatively poor prognosis.

Abstract
The human papilloma virus (HPV) infection, caused by a ubiquitous virus typically transmitted through the direct contact of infected organs, either through the skin or mucosa, is the most common sexually transmitted infection, placing young women at a high risk of contracting it. Although the vast majority of cases spontaneously clear within 1-2 years, persistent HPV infection remains a serious concern, as it has repeatedly been linked to the development of multiple malignancies, including cervical, anogenital, and oropharyngeal cancers. Additionally, more recent data suggest a harmful effect of HPV infection on pregnancy. As the maternal hormonal environment and immune system undergo significant changes during pregnancy, the persistence of HPV is arguably favored. Various studies have reported an increased risk of adverse pregnancy outcomes among HPV-positive women, with the clinical impact encompassing a range of conditions, including preterm birth, miscarriage, pregnancy-induced hypertensive disorders (PIHD), intrauterine growth restriction (IUGR), low birth weight, the premature rupture of membranes (PROM), and fetal death. Therefore, understanding the mechanisms employed by HPV that negatively impact pregnancy and assessing potential approaches to counteract them would be of interest in the quest to optimize pregnancy outcomes and improve child survival and health.

Abstract
BACKGROUND/AIM The incidence of early pregnancy loss widely varies according to age, being considerably higher in older women. Severe congenital malformations play an important role in pregnancy loss, having a high risk of recurrence. Congenital heart defects are the most common congenital abnormalities, thus the diagnosis of such malformations in aborted embryos is important for establishing both a possible cause for pregnancy loss and for correctly counseling the parents. Pathologic examination of the heart that is only a few millimeters in size, is very challenging. PATIENTS AND METHODS A pathologic examination protocol using transverse microscopic sections at the level of the 4-chamber and 3-vessel planes is proposed for heart evaluation. RESULTS Two 9-10 gestational weeks embryos were microscopically examined using transverse slides of the thorax. The 4-chamber and 3-vessel slides were analyzed and compared to 11-13 weeks ultrasound images of the 4-chamber and 3-vessel views from 10 cases. The pathologic examination provided a detailed view of the ventricles, atria and great vessels, sometime surpassing even the ultrasound examination that was performed at a later gestational age. CONCLUSION We consider our proposed pathologic examination protocol feasible for evaluating normal heart structures and ruling out severe congenital heart disease.

Abstract
Ovarian cancer is one of the most common causes of death in women as survival is highly dependent on the stage of the disease. Ovarian cancer is typically diagnosed in the late stage due to the fact that in the early phases is mostly asymptomatic. Genomic instability is one of the hallmarks of ovarian cancer. While ovarian cancer is stratified into different clinical subtypes, there still exists extensive genetic and progressive diversity within each subtype. Early detection of the disorder is one of the most important steps that facilitate a favorable prognosis and a good response to medical therapy for the patients. In targeted therapies, individual patients are treated by agents targeting the changes in tumor cells that help them grow, divide and spread. Currently, in gynecological malignancies, potential therapeutic targets include tumor-intrinsic signaling pathways, angiogenesis, homologous-recombination deficiency, hormone receptors, and immunologic factors. Ovarian cancer is usually diagnosed in the final stages, partially due to the absence of an effective screening strategy, although, over the times, numerous biomarkers have been studied and used to assess the status, progression, and efficacy of the drug therapy in this type of disorder.

Abstract
Invasive breast cancer is a heterogeneous disease, both in its histopathological classification and clinical course. Glycogen-rich clear cell carcinoma of the breast is an extremely rare subtype of invasive breast carcinoma, accounting for up to 3% of all breast carcinomas. The tumor is composed of polygonal cells with abundant clear cytoplasm containing glycogen and has a very controversial prognosis. Solid papillary pattern is an uncommon morphological variant of breast carcinoma which is associated with indolent behavior in the absence of an invasive component. To date, there are only three cases of glycogen-rich clear cell carcinoma with solid papillary pattern reported in the English literature. In this article, we present two cases of glycogen-rich clear cell carcinoma of the breast, encountered in our daily clinical practice over a period of 5 years (2015-2020) and perform a brief review of currently published literature. Unlike most cases of glycogen-rich clear cell carcinoma documented to date, follow-up of our case featuring solid papillary pattern revealed extremely favorable clinical outcome, suggesting a better prognosis for tumors with this morphology.

Abstract
MicroRNAs applications were vastly studied throughout the years, spanning from potential cancer biomarkers to targeted therapies for various diseases. Out of these utilizations, this paper focuses on their role in male infertility. Approximately 10–15% of worldwide couples are affected by infertility. Out of these, 50% are due to male determinants. The majority of cases still have an undetermined cause. Previous studies have found that the aberrant expression of microRNAs could be linked to certain reproductive dysfunctions in males. Further on, this study looked into the most recent literature published on this subject in order to assess the connection between the up-/down-regulation of various microRNAs and the roles they play in male infertility. MicroRNAs were found to be abundant and stable in the seminal liquid, which led to a facile identification using regular RNA detection methods. It was observed that the concentration of microRNAs in semen was modified in the case of patients suffering from asthenozoospermia and azoospermia. Moreover, idiopathic male infertility was associated with a single nucleotide polymorphism of the microRNA binding site. Future studies should focus their attention on discovering future treatments against male infertility targeting specific microRNAs and also on developing new and improved contraceptive methods.

Abstract
Introduction: Lymph node metastasis is regarded as an important prognostic factor for predicting disease recurrence and survival in patients with colorectal cancer. Several studies suggest that the lymph node ratio has a greater importance in survival than the number of metastatic lymph nodes. The scope of this study is to examine the 5-year survival of rectal cancer patients, examining several prognostic factors with emphasis on lymph node status. Material and Methods: A retrospective study was conducted at single surgical clinic from Romania, using data from patients who have been treated for rectal cancer between January 2009 and December 2014. Patient present status and regarding the multimodal treatment was assessed through telephonic method, data was extracted from the electronic database of the clinic and histopathological reports. Results: A total number of 144 patients affected by rectal cancer were assessed. Statistical analysis of the variables showed that age (p=0.001), T stage(p=0.049), N stage (p=0.005), LNR (p=0.006), type of surgery (p 0.001), presence of vascular invasion (p 0.001), metastases (p 0.001), to be significant prognostic factors for survival. Conclusions: The 5-year survival of the patients we included in the study was 63,9%. Nodal status, expressed by lymph node ratio proved to be a significant prognostic factor of patient survival.

Abstract
Polycystic ovary syndrome (PCOS) is a complex disorder that affects around 5% to 10% of women of childbearing age worldwide, making it the most common source of anovulatory infertility. PCOS is defined by increased levels of androgens, abnormal ovulation, irregular menstrual cycles, and polycystic ovarian morphology in one or both ovaries. Women suffering from this condition have also been shown to frequently associate certain cardiovascular comorbidities, including obesity, hypertension, atherosclerosis, and vascular disease. These factors gradually lead to endothelial dysfunction and coronary artery calcification, thus posing an increased risk for adverse cardiac events. Traditional markers such as C-reactive protein (CRP) and homocysteine, along with more novel ones, specifically microRNAs (miRNAs), can accurately signal the risk of cardiovascular disease (CVD) in PCOS women. Furthermore, studies have also reported that increased oxidative stress (OS) coupled with poor antioxidant status significantly add to the increased cardiovascular risk among these patients. OS additionally contributes to the modified ovarian steroidogenesis, consequently leading to hyperandrogenism and infertility. The present review is therefore aimed not only at bringing together the most significant information regarding the role of oxidative stress in promoting CVD among PCOS patients, but also at highlighting the need for determining the efficiency of antioxidant therapy in these patients.

Abstract
Accumulated evidence on the clinical roles of microRNAs (miRNAs) in cancer prevention and control has revealed the emergence of new genetic techniques that have improved the understanding of the mechanisms essential for pathology induction and progression. Comprehension of the modifications and individual differences of miRNAs and their interactions in the pathogenesis of gynecological malignancies, together with an understanding of the phenotypic variations have considerably improved the management of the diagnosis and personalized treatment for different forms of cancer. In recent years, miRNAs have emerged as signaling molecules in biological pathways involved in different categories of cancer and it has been demonstrated that these molecules could regulate cancer-relevant processes, our focus being on malignancies of the gynecologic tract. The aim of this paper is to summarize novel research findings in the literature regarding the parts that miRNAs play in cancer-relevant processes, specifically regarding gynecological malignancy, while emphasizing their pivotal role in the disruption of cancer-related signaling pathways.

Abstract
Background: The SARS-CoV2 infection has rapidly spread throughout the world, particularly affecting those with underlying conditions. Objective: To assess the impact of SARS-CoV-2 on the most prevalent comorbidities, among people who died of COVID-19 in Romania. Methods: The study comprised 814 deaths caused by COVID-19 between 22nd March and 8th May, 2020 as reported by the Ministry of Health. WHO data regarding deaths of the general population of Romania was used for comparison. The study analyzed the demographics, number and prevalence of comorbidities and calculated the relative risk for each comorbidity. Results: The study sample consisted of 61.4% males and 38.6% females; the mean age was 68.2 y; 90.9% of deaths occurred in people 50+ years. The mean number of pre-existing conditions was 2.73 (SD = 1.521), with 97.4% of the patients having at least one. The most prevalent comorbidities were hypertension (43.1%), diabetes (33.2%), and coronary heart disease (26.0%). The calculated relative risk of death due to COVID-19 was divided into 3 risk categories: high impact comorbidities (RR > 3) included diabetes RR = 6.426 (95% CI, 4.965–8.318), chronic renal disease RR = 4.338 (95% CI, 3.556–5.292) and hypertension RR=3.261 (95% CI, 2.687–3.958). The medium impact (RR = 2–3) group comprised chronic pulmonary disease RR = 2.615 (95% CI, 2.061–3.319) and chronic liver disease RR = 1.577 (95% CI, 1.183–2.104) and the low impact group (RR<2) –coronary heart disease RR = 0.664 (95% CI, 0.581–0.758), cancer RR = 0.515 (95% CI, 0.416–0.637) and stroke RR = 0.468 (95% CI, 0.370–0.593). Conclusion: In the studied sample, SARS-CoV-2 had a greater impact on people with diabetes, chronic renal disease and hypertension and a lesser impact on those with coronary heart disease, cancer and stroke. Therefore, future policies in Romania should focus on shielding people in the high-risk group and prioritizing them for vaccination, whilst encouraging those in the low risk group to continue seeking treatment for their underlying diseases.

Abstract
Objective: Congenital heart disease (CHD) is the most common birth defect and represents the leading cause for mortality and morbidity in infants and young adults. Early fetal echocardiography is usually considered a highly specialized scan. The goal of this study is to evaluate the impact of operator's experience in assessing still images of the 4-chamber view and 3-vessels view and to evaluate the feasibility and the performance of a first trimester screening protocol for CHD.Methods: An online questionnaire consisting of still images of the 4-camber view and 3-vessel view from 50 normal and abnormal cases was reviewed by an expert group made of seven obstetricians specialized in fetal medicine and a nonexpert group made of 13 obstetricians that are certified in ultrasound. After individually visualizing each image set made of the 4-chamber view and 3-vessel view, they had to conclude if the case was normal or abnormal and what images were abnormal.Results: A total of 50 image sets of both normal and abnormal fetal hearts were examined by the 20 reviewers, resulting in 1000 evaluations. The expert group achieved a detection rate of 97.1% with a false positive rate of 5.7%. The nonexpert group achieved also a good detection rate of 91.3% but with a much higher false positive rate of 33.9%. The most frequently missed CHD involved the great arteries and had a normal 4-chamber view. In the majority of false positive cases the 3-vessel view was incorrectly interpreted as abnormal.Conclusions: A screening protocol for CHD, based on the 4-chamber view and 3-vessel view alone can offer a good detection rate for CHD with a small false positive rate, but only if it is implemented by highly specialized sonographers.

Abstract
The study of miRNAs started in 1993, when Lee et al. observed their involvement in the downregulation of a crucial protein known as LIN-14 in the nematode Caenorhabditis elegans. Since then, great progress has been made regarding research on microRNAs, which are now known to be involved in the regulation of various physiological and pathological processes in both animals and humans. One such example is represented by their interaction with various signaling pathways during viral infections. It has been observed that these pathogens can induce the up-/downregulation of various host miRNAs in order to elude the host’s immune system. In contrast, some miRNAs studied could have an antiviral effect, enabling the defense mechanisms to fight the infection or, at the very least, they could induce the pathogen to enter a latent state. At the same time, some viruses encode their own miRNAs, which could further modulate the host’s signaling pathways, thus favoring the survival and replication of the virus. The goal of this extensive literature review was to present how miRNAs are involved in the regulation of various signaling pathways in some of the most important and well-studied human viral infections. Further on, knowing which miRNAs are involved in various viral infections and what role they play could aid in the development of antiviral therapeutic agents for certain diseases that do not have a definitive cure in the present. The clinical applications of miRNAs are extremely important, as miRNAs targeted inhibition may have substantial therapeutic impact. Inhibition of miRNAs can be achieved through many different methods, but chemically modified antisense oligonucleotides have shown the most prominent effects. Though scientists are far from completely understanding all the molecular mechanisms behind the complex cross-talks between miRNA pathways and viral infections, the general knowledge is increasing on the different roles played by miRNAs during viral infections.

Abstract
Romania has drastically improved an array of health indicators in recent years, including maternal mortality rates, which decreased from 1990 to 2015, but the mortality rates are still high, ranking among the first in Europe. Preeclampsia and eclampsia constitute one of the primary causes of maternal death in the country. The study was conducted from early January to the end of February 2019 to assess the current state of resident physicians’ and midwives’ knowledge of preeclampsia and eclampsia reflected in their practice at a clinical hospital in southern Romania. Self-administered questionnaires were used for data collection. Most of the investigated resident physicians and midwives (87.5%) answered correctly regarding the correct definition of preeclampsia. The first choice of procedure for the patient with preeclampsia (vaginal delivery or C-section) was chosen correctly by only 37.5% of the participants. Regarding the correct identification of the necessary paraclinical tests used for women with suspected preeclampsia, 58.3% of the participants answered correctly. As far as the correct identification of the possible risks of dexamethasone administration to mothers is concerned, only 29.2% of the participants answered correctly. Also, 58.3% of the participants answered correctly regarding the correct identification of contraindicated uterotonic drugs for women with diagnosed hypertension. Resident physicians and midwives are aware of pregnancy complications, but they hold limited knowledge specific to pregnancy complications as preeclampsia and eclampsia. It is imperative to promote studies to evaluate the impact of enhancing their training to include additional content related to the early detection and management of preeclampsia and eclampsia.

Abstract
MicroRNAs (miRNAs) represent a class of small, non-coding RNAs with the main roles of regulating mRNA through its degradation and adjusting protein levels. In recent years, extraordinary progress has been made in terms of identifying the origin and exact functions of miRNA, focusing on their potential use in both the research and the clinical field. This review aims at improving the current understanding of these molecules and their applicability in the medical field. A thorough analysis of the literature consulting resources available in online databases such as NCBI, PubMed, Medline, ScienceDirect, and UpToDate was performed. There is promising evidence that in spite of the lack of standardized protocols regarding the use of miRNAs in current clinical practice, they constitute a reliable tool for future use. These molecules meet most of the required criteria for being an ideal biomarker, such as accessibility, high specificity, and sensitivity. Despite present limitations, miRNAs as biomarkers for various conditions remain an impressive research field. As current techniques evolve, we anticipate that miRNAs will become a routine approach in the development of personalized patient profiles, thus permitting more specific therapeutic interventions.

Abstract
G-coupled protein receptors (GCPR) involve several signaling pathways, some of them being coupled with intracellular calcium (Ca2+) mobilization. GPCRs were involved in migration, invasion and metastasis of different types of cancers, including ovarian cancer. Many studies have discussed the essential contribution of GPCRs activated by steroid hormones in ovarian cancer. However, ovarian cancer is also associated with altered signals coming from the nervous system, the immune system or the inflammatory environment, in which GPCRs are ‘sensing’ these molecular signals. Many studies have been oriented so far on ovarian cell lines (most of them being of human cell lines), and only few studies based on animal models or clinical studies have been devoted to the expression changes or functional role of GPCRs in ovarian cancer. In this paper, we review the alterations of GPCRs activated by neurotransmitters (muscarinic receptors, serotonin receptors, dopamine receptors, adrenoceptors) or inflammation-associated molecules (bradykinin receptors, histamine receptors, chemokine receptors) in ovarian cancer and we discuss their potential as histological biomarkers.

Abstract
The acquisition of the infant�s microbiota is a vastly researched subject and of high interest. As more information is gathered, scientists prove the link between an unbalanced microbiome and certain afflictions. Antibiotics are widely used drugs and one of the factors that can shape the composition of the infant�s gut bacterial colonization. In this paper we aim to present the natural history of the child�s microbiome and the way it can be influenced by the use of antibiotics.

Abstract
Postpartum depression is a serious and frequent condition that affects a significant proportion of new mothers in developed countries. Despite its high prevalence and proven deleterious outcomes for both mother and child, there remains an increasing need to expand our knowledge regarding new methods that ensure the discovery of at-risk patients. Many theories have been developed over the years, mainly focusing on hormonal imbalances that occur after childbirth. This review has the purpose to analyze the existing literature and to summarize the latest findings on neuroactive molecules which may predict postpartum depression in new mothers.

Abstract
Iodine is a fundamental component of thyroxine (T4) and tri-iodothyronine (T3), thyroid hormones which are essential for the natural growth and development of the child. Pregnant women are required to generate higher amounts of thyroid hormones in order to meet both their own and their children�s needs, therefore iodine intake should be enhanced by over 50% during this period. The normal neurodevelopment of the fetus is made possible through sufficient amounts of T3 available in the fetal brain, which are derived from the mother�s own free T4. Low levels of maternal free T4 that can be witnessed in iodine deficiency contribute to the poor neurodevelopment of the fetus. The most severe outcome of maternal iodine deficiency is, without doubt, cretinism. This review is therefore meant to highlight the necessity for more rigorous investigations into the extent and importance of maternal iodine deficiency in the child�s development.

Abstract
Preeclampsia is a multi-system disorder unique to human pregnancy with multi-system involvement. Worldwide, it causes ]500,000 fetal and neonatal deaths and ]70,000 maternal deaths every year. Limited knowledge of health professionals in direct connection with complications of pregnancy, and inability to keep up with medical knowledge, has potentially severe effects on the quality of care and increases maternal and perinatal mortality. The aim has been to identify the impact of an intensive educational program regarding preeclampsia on health professionals knowledge at Clinical Hospital of Obstetrics and Gynecology Polizu in Bucharest, Romania. The study design was quasi-experimental. A total of 89 health professionals, including 12 resident physicians, 12 midwives and 65 nurses at Clinical Hospital of Obstetrics and Gynecology Polizu in Bucharest in the Department of Obstetrics and Gynecology participated in the study. The study was designed in three phases: Assessment phase, Implementation phase and Evaluation phase. The intensive educational program regarding preeclampsia has a highly significant positive influence on the knowledge of health professionals. There was a clear transfer of knowledge among the participants. The following resulted across all 31 examined knowledge areas: Resident physicians: Category Score /Criteria Pre-Test (No./%): Inadequate 1 (8.3%), Moderate 9 (75%), Adequate 2 (16.7%), Midwives: Category Score /Criteria Pre-Test (No./%): Inadequate 8 (66.7%), Moderate 4 (33.3%), Adequate 0 (0%), Nurses: Category Score /Criteria Pre-Test (No./%): Inadequate 60 (92.3%), Moderate 5 (7.7%), Adequate 0 (0%). After Trainingsprogramm, the amount of knowledge in the field preeclampsia increased impressively: Resident physicians: Category Score /Criteria Post-Test (No./%): Inadequate 0 (0%), Moderate 0 (0%), Adequate 12 (100%), Midwives: Category Score /Criteria Post-Test (No./%): Inadequate 0 (0%), Moderate 3 (25%), Adequate 9 (75%) with a (p[0.002), Nurses: Category Score /Criteria Post-Test (No./%): Inadequate 0 (0%), Moderate 10 (15.4%), Adequate 55 (84.6%) with a (p[0.001). Based on the findings of the study, it can be concluded that the intensive educational program regarding preeclampsia led up updating of the knowledge and improved qualification of the health professionals. This is expected to improve the quality of care for patients and reduce maternal and perinatal preeclampsia-related mortality in Romania.

Abstract
In the management of preeclampsia/eclampsia, it would be useful at least at European level, to have clear protocols for early detection and approach of cases with hypertension, as well as to create an algorithm to identify the predisposition to hypertensive pregnancy pathology. The aim has been to identify the favorable factors and the evolution of the pregnancy in the 100 patients admitted to the obstetrics clinic between January 2014 and December 2018, aged between 15-44 years, who have been diagnosed with preeclampsia. In recent years, the management of pregnant women with preeclampsia has improved a lot due to a better understanding of the pathogenesis and a refinement of adequate pregnancy monitoring. Obesity has been shown to be a risk factor in preeclampsia. Several studies have identified preeclampsia as an inflammatory condition. A large number of inflammatory markers, such as C-reactive protein (PCR) and Interleukin 6 (IL-6), have been shown to be elevated in pregnant women with preeclampsia.

Abstract
In the last years, procalcitonin (PCT) has been proposed as an early marker of infections in newborns having registered different results. In this study, we aimed to investigate the value of serum procalcitonin for the diagnosis of sepsis in neonates and children procalcitonin in the diagnosis of neonatal sepsis and in children up to 1 year in the pathology of therespiratory system, gastrointestinal pathology, etc. At first, we established the clinical and paraclinical signs of systemic inflammation: increasing the temperature of the system, tachycardia, laboratory test: leukocytosis, C-reactive protein - for the diagnosis of sepsis.Some studies show that PCT gave a sensitivity between 83-100% and a specificity between 70-100% in early diagnosis of neonatal sepsis [1-7]; other researches question the accuracy of PCT in detecting neonatal sepsis.Procalcitonin (PCT) has been proposed as a marker of bacterial sepsis in critically ill patients. PCT is a precursor of calcitonin and a 116 amino acids protein. PCT levels more than 0.5 mg/dl are useful to determine the type of infectious process (bacterial or not).

Abstract
The fields of toxicology and chemical risk assessment seek to reduce, and eventually replace, the use of animals for the prediction of toxicity in humans. In this context, physiologically based kinetic (PBK) modelling based on in vitro and in silico kinetic data has the potential to a play significant role in reducing animal testing, by providing a methodology capable of incorporating in vitro human data to facilitate the development of in vitro to in vivo extrapolation of hazard information. In the present article, we discuss the challenges in: 1) applying PBK modelling to support regulatory decision making under the toxicology and risk-assessment paradigm shift towards animal replacement; 2) constructing PBK models without in vivo animal kinetic data, while relying solely on in vitro or in silico methods for model parameterization; and 3) assessing the validity and credibility of PBK models built largely using non-animal data. The strengths, uncertainties, and limitations of PBK models developed using in vitro or in silico data are discussed in an effort to establish a higher degree of confidence in the application of such models in a regulatory context. The article summarises the outcome of an expert workshop hosted by the European Commission Joint Research Centre (EC-JRC) - European Union Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM), on "Physiologically-Based Kinetic modelling in risk assessment - reaching a whole new level in regulatory decision-making" held in Ispra, Italy, in November 2016, along with results from an international survey conducted in 2017 and recently reported activities occurring within the PBK modelling field. The discussions presented herein highlight the potential applications of next generation (NG)-PBK modelling, based on new data streams.

Abstract
Worldwide, 5-8% of pregnant women are diagnosed with preeclampsia. This disease increases the morbidity and mortality of the fetus and pregnant woman, especially in developing countries. Preeclampsia is characterized by systolic blood pressure ] 140mmHg or diastolic blood pressure] 90mmHg as measured twice, and 24 h proteinuria �0.3 g, after 20 weeks of gestation. The cause of preeclampsia is still incompletely elucidated. Numerous studies have suggested to modernize the definition of preeclampsia by incorporating key biomarkers of either placental or vascular origins, including placental growth factor (PIGF) and antiangiogenic factors such as tyrosine kinase-1 (sFlt-1) in the diagnosis of preeclampsia and the risk of occurrence of the disease in the second trimester of pregnancy [1-5]. We studied a group of 50 patients with a 21-week pregnancy diagnosis, we calculated the ratio between sFlt-1 and PIGF and we tested to see if there was an association between this ratio and the resistivity index (IR) of the uterine artery using the artery Doppler ultrasound. The PIGF level in our group was decreased in women who developed preeclampsia compared to the control group where this problem did not occur. Doppler ultrasound examination during the second trimester of pregnancy may provide extra data for prediction of preeclampsia. Although much of pathophysiology of preeclampsia has been explained, the exact etiology of this disorder remains unclear. It is certain that before the clinical signs of preeclampsia are detectable, there is an imbalance between pro-angiogenic and anti-angiogenic factors.

Abstract
In Romania it is estimated that there are half a million patients with endometriosis. The main symptoms are pain (70% of patients with chronic pelvic pain have endometriosis) and infertility (50% of infertile patients have endometriosis). It is difficult to make an accurate diagnosis. Numerous studies show a 7-10-year delay in diagnosis in women in developing countries. 47% of patients should be seen by more than 5 physicians over time until the diagnosis is established. The treatment for endometriosis is the surgical procedure and it is most often performed laparoscopically. The present study was carried in the Obstetrics and Gynecology Departments of the Pius Brinzeu Emergency Clinical Hospital Timisoara. We have included in this study patients who were hospitalized between 2013 and 2017. We have 142 patients who qualified for this study. All the patients had made the same medical tests: we collected information about their age, the neutrophil, lymphocyte and CA125 values, the position of the cyst and the cyst dimension. The aim of this study is to find if there is any association between the CA-125 markers (coelomic epithelial antigen) and the neutrophil-to-lymphocyte ratio in patients who were diagnosed with ovarian endometriosis by transvaginal ultrasound. In all cases the patients underwent laparoscopic surgery. After performing a correlation and regression analysis we obtained that we have a positive strong significant association between the CA 125 values and the ratio values (r=0.94; R2=0.88; p[0.001) . After the surgical excision of endometriosis, CA-125 can be used to monitor the evolution of endometriosis outbreaks, especially when there is a recurring severe pain.

Abstract
Pesticides are key stressors of soil microorganisms with reciprocal effects on ecosystem functioning. These effects have been mainly attributed to the parent compounds, while the impact of their transformation products (TPs) has been largely overlooked. We assessed in a meadow soil (soil A) the transformation of iprodione and its toxicity in relation to (i) the abundance of functional microbial groups, (ii) the activity of key microbial enzymes, and (iii) the diversity of bacteria, fungi, and ammonia-oxidizing microorganisms (AOM) using amplicon sequencing. 3,5-Dichloroaniline (3,5-DCA), the main iprodione TP, was identified as a key explanatory factor for the persistent reduction in enzymatic activities and potential nitrification (PN) and for the observed structural changes in the bacterial and fungal communities. The abundances of certain bacterial (Actinobacteria, Hyphomicrobiaceae, Ilumatobacter, and Solirubrobacter) and fungal (Pichiaceae) groups were negatively correlated with 3,5-DCA. A subsequent study in a fallow agricultural soil (soil B) showed limited formation of 3,5-DCA, which concurred with the lack of effects on nitrification. Direct 3,5-DCA application in soil B induced a dose-dependent reduction of PN and NO3--N, which recovered with time. In vitro assays with terrestrial AOM verified the greater toxicity of 3,5-DCA over iprodione. "Candidatus Nitrosotalea sinensis" Nd2 was the most sensitive AOM to both compounds. Our findings build on previous evidence on the sensitivity of AOM to pesticides, reinforcing their potential utilization as indicators of the soil microbial toxicity of pesticides in pesticide environmental risk analysis and stressing the need to consider the contribution of TPs in the toxicity of pesticides on the soil microbial community.IMPORTANCE Pesticide toxicity on soil microorganisms is an emerging issue in pesticide risk assessment, dictated by the pivotal role of soil microorganisms in ecosystem services. However, the focus has traditionally been on parent compounds, while transformation products (TPs) are largely overlooked. We tested the hypothesis that TPs can be major contributors to the soil microbial toxicity of pesticides using iprodione and its main TP, 3,5-dichloroaniline, as model compounds. We demonstrated, by measuring functional and structural endpoints, that 3,5-dichloroaniline and not iprodione was associated with adverse effects on soil microorganisms, with nitrification being mostly affected. Pioneering in vitro assays with relevant ammonia-oxidizing bacteria and archaea verified the greater toxicity of 3,5-dichloroaniline. Our findings are expected to advance environmental risk assessment, highlighting the potential of ammonia-oxidizing microorganisms as indicators of the soil microbial toxicity of pesticides and stressing the need to consider the contribution of TPs to pesticide soil microbial toxicity.

Abstract
Muscle tissue is a highly specialized type of tissue, made up of cells that have as their fundamental properties excitability and contractility. The cellular elements that make up this type of tissue are called muscle fibers, or myofibers, because of the elongated shape they have. Contractility is due to the presence of myofibrils in the muscle fiber cytoplasm, as large cellular assemblies. Also, myofibers are responsible for the force that the muscle generates which represents a countless aspect of human life. Movements due to muscles are based on the ability of muscle fibers to use the chemical energy procured in metabolic processes, to shorten and then to return to the original dimensions. We describe in detail the levels of organization for the myofiber, and we correlate the structural aspects with the functional ones, beginning with neuromuscular transmission down to the biochemical reactions achieved in the sarcoplasmic reticulum by the release of Ca2+ and the cycling of crossbridges. Furthermore, we are reviewing the types of muscle contractions and the fiber-type classification.

Abstract
Hydroxyl radical (.OH) is highly reactive, and therefore very short-lived. Finding new means to accurately detect .OH, and testing the ability of known .OH scavengers to neutralize them in human biological fluids would leverage our ability to more effectively counter oxidative (.OH) stress-mediated damage in human diseases. To achieve this, we pursued the evaluation of secondary products resulting from .OH attack, using a detection system based on Fenton reaction-mediated D-phenylalanine (D-Phe) hydroxylation. This reaction in turn generates o-tyrosine (o-tyr), m-tyrosine (m-tyr) and p-tyrosine (p-tyr). Here, these isomers were separated by HPLC, equipped with fluorescence detectors due to the natural fluorescence of these hydrotyrosines. By extension, we found that, adding radical scavengers competed with D-Phe on .OH attack, thus allowing to determine the .OH quenching capacity of a given compound expressed as inhibition ratio percent (IR%). Using a kinetic approach, we then tested the .OH scavenging capacity (OHSC) of well-known antioxidant molecules. In a test tube, N,N'-dimethylthiourea (DMTU) was the most efficient scavenger as compared to Trolox and N-Acethyl-L-cysteine, with NAC being the less effective. OHSC assay was then applied to biological fluid samples as seminal plasma, human serum from normal subjects and patients undergoing hemodialysis (HD), colostrum and human breast milk from mothers that received daily doses of 30g of chocolate (70% cocoa) during pregnancy. We found that a daily administration of dark chocolate during pregnancy almost doubled OHSC levels in breast milk (1.88 ± 0.12 times, p < 0.01). Furthermore, HD treatment determined a significant reduction of serum OHSC concentration (54.63 ± 2.82%, p < 0.001). Our results provide evidence that Fenton reaction-mediated D-Phe hydroxylation is a suitable method for routine and non-invasive evaluation of .OH detection and its scavenging in human biological fluids.

Abstract
A limited number of microRNAs (miRNAs, miRs) have been reported to control postnatal cardiomyocyte proliferation, but their strong regulatory effects suggest a possible therapeutic approach to stimulate regenerative capacity in the diseased myocardium. This study aimed to investigate the miRNAs responsible for postnatal cardiomyocyte proliferation and their downstream targets. Here, we compared miRNA profiles in cardiomyocytes between postnatal day 0 (P0) and day 10 (P10) using miRNA arrays, and found that 21 miRNAs were upregulated at P10, whereas 11 were downregulated. Among them, miR-31a-5p was identified as being able to promote cardiomyocyte proliferation as determined by proliferating cell nuclear antigen (PCNA) expression, double immunofluorescent labeling for α-actinin and 5-ethynyl-2-deoxyuridine (EdU) or Ki-67, and cell number counting, whereas miR-31a-5p inhibition could reduce their levels. RhoBTB1 was identified as a target gene of miR-31a-5p, mediating the regulatory effect of miR-31a-5p in cardiomyocyte proliferation. Importantly, neonatal rats injected with a miR-31a-5p antagomir at day 0 for three consecutive days exhibited reduced expression of markers of cardiomyocyte proliferation including PCNA expression and double immunofluorescent labeling for α-actinin and EdU, Ki-67 or phospho-histone-H3. In conclusion, miR-31a-5p controls postnatal cardiomyocyte proliferation by targeting RhoBTB1, and increasing miR-31a-5p level might be a novel therapeutic strategy for enhancing cardiac reparative processes.

Abstract
An important step in building a computational model is its documentation; a comprehensive and structured documentation can improve the model applicability and transparency in science/research and for regulatory purposes. This is particularly crucial and challenging for environmental and/or human exposure models that aim to establish quantitative relationships between personal exposure levels and their determinants. Exposure models simulate the transport and fate of a contaminant from the source to the receptor and may involve a large set of entities (e.g. all the media the contaminants may pass though). Such complex models are difficult to be described in a comprehensive, unambiguous and accessible way. Bad communication of assumptions, theory, structure and/or parameterization can lead to lack of confidence by the user and it may be source of errors. The goal of this paper is to propose a standard documentation protocol (SDP) for exposure models, i.e. a generic format and a standard structure by which all exposure models could be documented. For this purpose, a CEN (European Committee for Standardisation) workshop was set up with objective to agree on minimum requirements for the amount and type of information to be provided on exposure models documentation along with guidelines for the structure and presentation of the information. The resulting CEN workshop agreement (CWA) was expected to facilitate a more rigorous formulation of exposure models description and the understanding by users. This paper intends to describe the process followed for defining the SDP, the standardisation approach, as well as the main components of the SDP resulting from a wide consultation of interested stakeholders. The main outcome is a CEN CWA which establishes terms and definitions for exposure models and their elements, specifies minimum requirements for the amount and type of information to be documented, and proposes a structure for communicating the documentation to different users.

Abstract
MERLIN-Expo is a library of models that was developed in the frame of the FP7 EU project 4FUN in order to provide an integrated assessment tool for state-of-the-art exposure assessment for environment, biota and humans, allowing the detection of scientific uncertainties at each step of the exposure process. This paper describes the main features of the MERLIN-Expo tool. The main challenges in exposure modelling that MERLIN-Expo has tackled are: (i) the integration of multimedia (MM) models simulating the fate of chemicals in environmental media, and of physiologically based pharmacokinetic (PBPK) models simulating the fate of chemicals in human body. MERLIN-Expo thus allows the determination of internal effective chemical concentrations; (ii) the incorporation of a set of functionalities for uncertainty/sensitivity analysis, from screening to variance-based approaches. The availability of such tools for uncertainty and sensitivity analysis aimed to facilitate the incorporation of such issues in future decision making; (iii) the integration of human and wildlife biota targets with common fate modelling in the environment. MERLIN-Expo is composed of a library of fate models dedicated to non biological receptor media (surface waters, soils, outdoor air), biological media of concern for humans (several cultivated crops, mammals, milk, fish), as well as wildlife biota (primary producers in rivers, invertebrates, fish) and humans. These models can be linked together to create flexible scenarios relevant for both human and wildlife biota exposure. Standardized documentation for each model and training material were prepared to support an accurate use of the tool by end-users. One of the objectives of the 4FUN project was also to increase the confidence in the applicability of the MERLIN-Expo tool through targeted realistic case studies. In particular, we aimed at demonstrating the feasibility of building complex realistic exposure scenarios and the accuracy of the modelling predictions through a comparison with actual measurements.

Abstract
MicroRNAs represent nonprotein coding small RNA molecules that are very stable to degradation and responsible for gene silencing in most eukaryotic cells. Increased evidence has been accumulating over the years about their potential value as biomarkers for several diseases. MicroRNAs were predicted to be involved in nearly all biological processes from development to oncogenesis. In this review, we address the importance of circulating microRNAs in different conditions associated with pregnancy starting with the implantation period to preeclampsia and we shortly describe the correlation between placental circulating miRNAs and pregnancy status. We also discuss the importance of microRNAs in recurrent abortion and ectopic pregnancy.

Abstract
BACKGROUND Although most postmenopausal women diagnosed with endometrial cancer usually present with vaginal bleeding, when complete cervical stenosis is present, this sign may be missing. In these cases, the patient usually complaints for pelvic or abdominal pain while the transvaginal ultrasonography might reveal the presence of an intrauterine fluid collection in association with a thickened endometrial lining. CASE REPORT We present the case of a 65-year-old patient who presented with association of pelvic pain, enlarged uterine cavity with an underlying hematometra and an irregular, thickened endometrium who was submitted to surgery for total histerectomy, bilateral adnexectomy, pelvic and para-aortic lymph node dissection. CONCLUSION Histopathological studies revealed the presence of a well-differentiated endometrial adenocarcinoma. At three years of follow-up, the patient is free of any recurrent disease.

Abstract
Objective To assess iodine status (median urinary iodine concentration) in 118 pregnant women during the third trimester from endemic or non-endemic areas, a decade after implementation of Universal Salt Iodization in Romania. Subjects and methods One hundred and eighteen pregnant women in the third trimester were included in the study group (age range: 16 - 46 years, mean age: 28.78 years). Median urinary iodine concentration (UIC) and body mass index (BMI) were evaluated. Data regarding region of provenance, smoking habits during pregnancy, education level, iodized salt intake, bread intake, iodine supplements, comorbidities (iron deficiency anemia) and birth weight were assessed. Morning urine was collected to measure median UIC. The study was approved by the Local Ethics Committee. Results Median UIC in the study group was 206 mcg/L, reflecting iodine sufficiency during pregnancy. There is a statistically significant difference between pregnant women with and without iodine supplements from rural areas (281.5 versus 196.1 mcg/L, respectively, p=0.023). In the subgroup without iodine supplementation, there was a significant difference between overweight and obese subjects vs. normal weight subjects (232.5 versus 194 mcg/L, p=0.012). Only in the subgroup with a daily intake of less than 5 slices of bread (usually containing iodized salt) we found significant differences between those with and without iodine supplements (245.2 versus 128.3 mcg/L). Iron deficiency anemia was found in 29.66% and 19.49% were current smokers during pregnancy. Conclusions Median UIC in the study group was 206 mcg/L, reflecting iodine sufficiency during pregnancy. The difference between the subgroup with iodine supplements and the subgroup without iodine supplements was not statistically significant, probably due to the excessive consumption of bread and other bakery products which is traditional in Romania.

Abstract
Uterine fibroids or uterine leiomyomas are the most common benign tumors of the uterus among women of fertile age, while the etiology is still incompletely elucidated. The occurrence and development of the fibromatosis may be related to certain risk factors and genic mechanisms, although the exact causes are not yet fully known. The development of uterine fibroids is correlated not only with the metabolism and with the level of female sexual hormones, estrogen, and progesterone, but also with the number of these hormone receptors expressed on the surface of the myometrium. Proliferative effects of estrogen and progesterone may be exercised through proinflammatory factors (TNF alpha), growth factors (IGF1, IGF2, TGFbeta3 and betaFGF) or inhibitors of apoptosis (p53 suppression). A number of predisposing factors such as ethnicity - black skin, early menarche, nulliparity, caffeine and alcohol, chronic inflammation, obesity, were also identified. Approximately 40% of the uterine fibroids are caused by the same cytogenetic alterations found in the other tumor types such as kidney, lung, or leiomyosarcoma. As part of a system dysfunction, uterine fibromatosis was connected to other disorders such as AHT (arterial hypertension), endometrium adenocarcinoma, adenomyosis, endometriosis, diabetes mellitus, breast tumors, seemingly with a common causality. The action and effect of some hormonal imbalances over the various organs depend on the histological and local expression particularities of the various receptors, being the cause for many disorders, among which the uterine fibromatosis, coexisting or accompanying the later. This article examines and summarizes the latest data refreshed literature etiopathogenesis offering indicators of uterine fibroids.

Abstract
Introduction. Adenomyosis is a widespread disease usually affecting the late reproductive years of the women's life, which has a great impact on their fertility. The most common form is diffuse adenomyosis, while focal adenomyosis, a cystic variant, is very rare, particularly in patients younger than 30 years old. Materials and methods. We reported a rare case of a 20-year-old Caucasian woman with cystic adenomyosis who was admitted in our service with severe chronic pelvic pain, dysmenorrhea, and menorrhagia, who had received conservative surgical treatment to preserve fertility and improve her obstetrical prognosis. Results and Discussions. Although the necrobiosis of a uterine fibroid was suspected preoperatively, the extemporaneous histopathological exam revealed adenomyosis associated with fibroleiomyoma with hyaline dystrophy and multiple foci of endometriosis of cystic formation in the wall of a young woman without any risk factors. Conclusion. Although a rare lesion in young patients, cystic adenomyosis should be considered when chronic pelvic pain is exacerbated during menstruation and is associated with a uterine tumor. In young patients, the differential diagnosis should be made with uterine malformations (hematometra), necrobiosis of uterine fibroids, pelvic endometriosis. The surgical treatment should be conservative with the excision of the lesion, always taking into account fertility preservation in young patients.

Abstract
Endometrial stromal sarcomas are rare gynecologic malignancies characterized by the presence of cells that resemble those of the endometrial stroma during the prolipferative phase of the menstrual cycle. They are classified as low grade or high grade tumors depending on the mitotic index, the second one being usually associated with poor prognosis and high recurrence rate. We present the case of a 46-year-old patient who was previously submitted to surgery for an endometrial stromal sarcoma followed by adjuvant radiotherapy; 18 months later she was diagnosed with a pelvic recurrence invading the urinary bladder trigone and the rectosigmoid so she was submitted to a total pelvic exenteration.

Abstract
Celiac disease (CD) is characterized by an abnormal immune response in susceptible individuals to dietary gluten derived from wheat, rye and barley. The disease affects not only the small bowel mucosa, but also many other extraintestinal organs resulting bone, liver, neurologic, skin and reproductive system disorders. The details of the pathogenic mechanism are not perfectly clear yet, but it is now proved that both humoral and cellular immune responses are triggered and autoimmune mechanisms are implicated. Studies have shown association of different pregnancy outcomes with maternal celiac disease. In this review, the most frequent fetal and neonatal outcome related to CD are presented, with a special focus on intrautherine growth restriction (IUGR) and prematurity. The need of active case finding of CD is discussed.

Abstract
Fetal tumors are rare and can be difficult to diagnose in utero. In this presentation, we report an infantile hemangiopericytoma of the tongue, and also review the clinical characteristics, imaging appearances, perinatal differential diagnosis, and potential treatments of this tumors. Prenatal diagnosis of lingual fetal tumors with two-dimensional (2D) ultrasound presents a challenge to sonographers and perinatologists because these lesions are rare, usually develop in the third trimester of pregnancy and need a multidisciplinary approach. We describe an lingual tumor and moderate polyhydramnios which were prenatally detected at 31 weeks of gestation with two- dimensional ultrasound. The application of the surface mode of three-dimensional ultrasound improved the visualization of this tumor. Fetal Magnetic resonance imaging was performed to help in prenatal differential diagnostic. The option of prenatal cytology gained by amniocentesis should also be considered. To our knowledge there are no prenatal reports of similar cases. However, in our experience every information provided during the pregnancy, a correct and early diagnose of fetal condition helps to cope with the demands of perinatal management and to explain to the parents and neonatologists the findings of the case.

Abstract
Insulin-like growth factor-I (IGF-I) has been shown to stimulate extravillous trophoblast (EVT) cell migration and invasion, and to play a crucial role in placental function, thereby, influencing placental development and fetal growth. Insufficient invasion of EVT cells into the uterine endometrium leads to pregnancy-related complications, including spontaneous abortion, fetal growth restriction (FGR), and pregnancy-induced hypertension (PIH). Insulin-resistant conditions such as polycystic ovary syndrome (PCOS) and gestational diabetes mellitus (GDM) have also been associated with abortion and PIH. However, the effects of IGF-I on EVT cells under insulin-resistant conditions have not been elucidated yet. The current study was undertaken to analyze the effects of IGF-I under insulin-resistant conditions and to determine whether improvement in insulin sensitivity alters IGF signaling and cell migration in the EVT. Incubation with pioglitazone, an insulin sensitizer, increased peroxisome proliferator-activated receptor-γ (PPARγ) expression after 48 h. A 48-h pre-incubation with insulin reduced the phosphorylation and concentration of the insulin receptors, which were increased by insulin treatment. Long-term exposure to insulin reduced phosphorylation of the IGF-I receptor, insulin receptor substrate-1 (IRS-1), and Akt, and also reduced EVT cell migration. However, when the cells were incubated with pioglitazone in addition to insulin for 48 h, the phosphorylation of these proteins was restored. This combination partially reversed the inhibitory effect of insulin on EVT cell migration. These results suggest that abnormalities in pregnancy that are induced by loss of insulin sensitivity can be treated by improving insulin sensitivity.
