Adapting surgical 'bundles' to prevent surgical site infections in obstetrics and gynecology (Review).

Surgical site infections (SSIs) are a complication in any surgical field and they are responsible for 38% of surgery-related patient deaths. Identifying appropriate prophylaxis and solutions to combat SSIs is of global interest. Several studies and reports on SSI raise awareness of this costly complication, both in terms of physical and mental suffering, and as a monetary burden. Knowing the risk factors and implementing strategies to reduce SSI risk represent an adequate approach to reduce SSI incidence. General risk factors of SSI are applicable in the obstetrics and gynecology field, alongside its specific characteristics, including immunological changes occurring during pregnancy, as well as disturbances of vaginal microbiota. The risk of SSI is determined by patient factors but also by preoperative, intraoperative and postoperative care. 'Bundle' prevention strategies have been smartly adopted and their efficiency has been demonstrated in colorectal surgery, cesarean deliveries and gynecological oncology surgeries. 'Bundle' measures may vary among studies, but they remain important prevention methods, which contribute to decreasing SSIs, which is a favorable outcome, and thus, are increasingly used as a routine practice. Therefore, healthcare personnel should aim for the early identification of risk factors to minimize the risk of SSI. All evidence-based methods for preventing and treating SSIs in all surgical fields should be considered to be integral components in order for the best care to be provided to patients.

SARS-CoV-2 Infection during Pregnancy and Histological Alterations in the Placenta.

(1) Background: Despite the high number of cases of COVID-19 during pregnancy, SARS-CoV-2 congenital infection is rare. The role of the placenta as a barrier preventing the transmission of SARS-CoV-2 from the mother to the fetus is still being studied. This study aimed to evaluate the impact of SARS-CoV-2 infection on placental tissue. (2) Methods: This was a transversal monocentric observational study. In the study, we included pregnant women with COVID-19 who delivered at "Sfântul Pantelimon" Clinical Emergency Hospital between 1 April 2020 and 30 March 2022. Histological analyses, both macroscopic and microscopic, were performed for placentas that came from these cases. (3) Results: To date, a characteristic placental lesion has not been clearly demonstrated, but most findings include features of maternal and fetal vascular malperfusion, which probably reflect the reduction in placental blood flow due to low oxygen level from the hypoxic respiratory disease and underlying hypercoagulable state induced by the COVID-19 infection. (4) Conclusions: The histopathological aspects found in placentas that came from COVID-19-positive pregnant women are common for many other diseases, but when they are found together, they are highly suggestive for viral infectious involvement of the placenta.

Fetal sacrococcygeal immature teratoma - report of two cases and review of the literature.

Sacrococcygeal teratomas (SCTs) are rare congenital tumors. With the improvement of diagnostic imaging methods and follow-up protocols in pregnancies, in utero detection of these tumors has increased. Despite these progresses, SCTs may present difficulties in establishing in utero diagnosis and subsequent management. We present two cases of SCT in 18 weeks, respectively 22 weeks pregnancy, diagnosed using ultrasound imaging and pathologically confirmed. Also, the article aims to recapitulate clinicopathological aspects and prognosis of these lesions, following the review of the literature.

The Risk of Obstetrical Hemorrhage in Placenta Praevia Associated with Coronavirus Infection Antepartum or Intrapartum.

Background and Objectives: The aim was to evaluate the severity of obstetrical bleeding in the third trimester associated with COVID infection in placenta previa and accreta. Materials and Methods: A retrospective study was conducted to compare the risk of obstetrical bleeding in the case of placenta previa with or without associated SARS-CoV-2 infection. Patients presenting with placenta previa before labor were classified into three groups: group A (control) as no infection throughout their pregnancy, group B as confirmed infection during the 1st trimester, and group C as confirmed infection at the time of delivery. Infected patients were stratified according to the severity of signs and symptoms. The severity of obstetrical hemorrhage at birth was assessed quantitatively and qualitatively. All placentas were analyzed histologically to identify similarities. Results: Prematurity and pregnancy-induced hypertension appear significantly related to SARS-CoV-2 infection during the 3rd trimester. Placenta accreta risk increases significantly with infection during the 1st trimester. No statistically significant differences in the severity of hemorrhage associated with childbirth in cases with placenta previa between groups A and C but increased obstetrical bleeding mainly due to emergency hemostatic hysterectomy in group B driven by placenta accrete were detected. Obstetrical hemorrhage at birth in the case of coexistence of the infection was found not to correlate with the severity of the viral disease. Meanwhile, the number of days of hospitalization after birth is related to the specific treatment of COVID infection and not related to complications related to birth. Conclusions: The study finds an increased incidence of placenta accreta associated with placenta previa in cases where the viral infection occurred in the first trimester of pregnancy, associated with an increased incidence of hemostasis hysterectomies in these patients. Placental histological changes related to viral infection are multiple and more important in patients who had COVID infection in the first trimester.

Ectopic Intrauterine Device Revealed by Ureteral Colic in a 37-Week Pregnant Woman: Case Report.

Copper T intrauterine devices (IUDs) are a popular long-acting reversible contraceptive method. The most common reasons for contraceptive failure are expulsion and extrauterine migration. We report a case of a 28-year-old female, G13P3, 37 weeks pregnant, who presented to the hospital for left abdominal flank pain. The patient was admitted for treatment of left ureteral colic. The woman went into labour, and Caesarean Section was performed due to foetal distress. During the surgery, an inspection of the peritoneal cavity revealed a copper IUD embedded in the granulous tissue located in the left lateral abdominal region, which was extracted. No uterine scar tissue could be identified macroscopically. The migration of an IUD in the abdominal cavity is a rare finding, and coexistence with third-trimester pregnancy is an infrequent but serious event due to potential visceral complications. Higher gravidity can be associated with an increased risk of IUD migration in women with a non-scarred uterus.

HELLP Syndrome-Holistic Insight into Pathophysiology.

HELLP syndrome, also known as the syndrome of hemolysis, elevated liver enzymes, and low platelets, represents a severe pregnancy complication typically associated with hypertension. It is associated with increased risks of adverse complications for both mother and fetus. HELLP occurs in 0.2-0.8% of pregnancies, and, in 70-80% of cases, it coexists with preeclampsia (PE). Both of these conditions show a familial tendency. A woman with a history of HELLP pregnancy is at high risk for developing this entity in subsequent pregnancies. We cannot nominate a single worldwide genetic cause for the increased risk of HELLP. Combinations of multiple gene variants, each with a moderate risk, with concurrent maternal and environmental factors are thought to be the etiological mechanisms. This review highlights the significant role of understanding the underlying pathophysiological mechanism of HELLP syndrome. A better knowledge of the disease's course supports early detection, an accurate diagnosis, and proper management of this life-threatening condition.

Animal Models in Bladder Cancer.

BACKGROUND: Bladder cancer (urothelial cancer of the bladder) is the most common malignancy affecting the urinary system with an increasing incidence and mortality. Mouse models of bladder cancer should possess a high value of reproducibility, predictability, and translatability to allow mechanistic, chemo-preventive, and therapeutic studies that can be furthered into human clinical trials. OBJECTIVES: To provide an overview and resources on the origin, molecular and pathological characteristics of commonly used animal models in bladder cancer. METHODS: A PubMed and Web of Science search was performed for relevant articles published between 1980 and 2021 using words such as: "bladder" and/or "urothelial carcinoma" and animal models. Animal models of bladder cancer can be categorized as autochthonous (spontaneous) and non-autochthonous (transplantable). The first are either chemically induced models or genetically engineered models. The transplantable models can be further subclassified as syngeneic (murine bladder cancer cells implanted into immunocompetent or transgenic mice) and xenografts (human bladder cancer cells implanted into immune-deficient mice). These models can be further divided-based on the site of the tumor-as orthotopic (tumor growth occurs within the bladder) and heterotopic (tumor growth occurs outside of the bladder).

Pheochromocytoma as a rare hypertensive complication rarely associated with pregnancy: Diagnostic difficulties (Review).

This review provides a brief clinically relevant review of pheochromocytoma in pregnancy, to raise awareness among doctors in obstetrics and the aim is to serve as the first point of reference when confronted by their presence. Pheochromocytomas are neuroendocrine, catecholamine-secreting tumours. Despite having the highest incidence rate among other hormone-secreting adrenal tumours, they remain rare especially when associated with pregnancy. The non-specific presentation of pheochromocytomas, the difficulties in their diagnosis during pregnancy as well as the high maternal and fetal mortality rates associated with them, present a challenge. Clinical suspicion and meticulous patient history-taking remain the primary lines of defense, while biochemical proof of catecholamine excess (or their metabolites) and imaging-based localisation of the tumour are required for diagnosis. Antenatal diagnosis and complete localisation of the tumour increase the likelihood of successful outcomes for both mother and newborn. Magnetic resonance imaging (MRI) remains the method of choice during pregnancy without excluding the use of ultrasound. Treatment goals should include the avoidance of hypertensive crises while maintaining adequate uteroplacental circulation. The target blood pressure is not strictly defined but is in line with the general guideline addressing chronic hypertension during pregnancy. Antihypertensive medications remain the cornerstone in managing pheochromocytoma. As a first-line, the α-adrenergic, nonselective antagonist phenoxybenzamine is the most frequently used agent, while α1-selective adrenergic antagonists with or without the addition of ß- or ß1-blockers are also prescribed in certain cases, rendering calcium channel blockers as 'second-choice'. Blood-pressure control of the mother and the well-being of the fetus are determining factors in deciding the time of delivery, which is preferably conducted by Caesarean section. Excision of the tumour(s) remains the final treatment goal. Lifelong biochemical testing is required with or without medical treatment, to address mineralocorticoid or glucocorticoid deficits. Despite ever-improving positive outcome rates, pheochromocytoma associated with pregnancy remains a pathology with high mortality and morbidity rates.

Use of platelet-rich plasma in the treatment of infertility in poor responders in assisted human reproduction procedures.

Couple infertility is a pathology with an absolute number of cases growing markedly over the last decade in connection mainly with the increased age of couples wishing to conceive. Platelet-rich plasma (PRP) is an alternative treatment used for several years for experimental purposes. Yet, this method is not yet defined as a standard therapeutic option in the infertility protocol for poor responders in assisted human reproduction procedures. Thus, the present study is a retrospective study conducted between February 2019 and February 2020 to evaluate the effect of ovarian PRP injection in patients with a poor ovarian response (POR) to ovarian stimulation. Women (n=20; age 31-44 years) diagnosed with POR based on the European Society of Human Reproduction and Embryology criteria underwent ovarian injection with autologous PRP injection. Markers of ovarian reserve before, during the following two menstrual cycles, and at six months after treatment were followed as well as stimulation and fertilisation parameters before and post-treatment. PRP treatment resulted in increased antral follicle count and serum anti-Mullerian hormone, while levels of serum follicle-stimulating hormone and luteinising hormone were decreased. These changes were more pronounced during the 2nd menstrual cycle following treatment. By six months following the injection, their values return to pre-treatment levels and any small differences were not considered statistically significant. The average dose of gonadotropin used and duration remained statistically unchanged, but a significant increase in estradiol achieved by the day of the human chorionic gonadotropin trigger day was achieved. The cancellation rate decreased following PRP treatment while the number of collected oocytes, number of oocytes in metaphase II rose. The number of embryos (of A and B quality) resulting also increased but fell short of the significance level set (α=0.073). Following the PRP injection, two singleton pregnancies were achieved, resulting in live births at term without complications during pregnancy. Another pregnancy was achieved spontaneously 45 months following the PRP and a failed assisted human reproduction procedure. Although the group included a small number of women, the results indicate the potential benefits of an ovarian autologous PRP injection in women with POR. Positive results appear to be short-term for 2-6 months after the procedure.

Fibroblast involvement in cardiac remodeling and repair under ischemic conditions.

Cardiac fibroblasts play a main role in the physiological turnover of the extracellular matrix, as well as its pathological remodeling. A study was performed on a batch of 23 cases who died of various cardiac complications secondary to scarring myocardial infarctions. The aim of the study was to assess the fibroblast involvement in cardiac repair under ischemic conditions after myocardial infarction. Tissue myocardial samples from the left ventricle were taken from these cases for microscopy examination, in order to investigate the type and degree of fibrosis as well as the presence of cardiac interstitial fibroblasts. Multiple series of histological sections were also performed and examined, along with immunohistochemical analysis. The fibroblasts were diffusely distributed in the interstitium among the residual cardiomyocytes, showing variable expression of vimentin and smooth muscle actin. During cardiac remodeling, there was a successive interstitial deposition, first of reticulin fibers and then of collagen fibers, leading to interstitial fibrosis and myocardial replacement. There was a correlation between vimentin and smooth muscle actin expression and collagen deposition. Fibrosis with cardiac remodeling is based on maintaining proliferation capacity of the fibroblast and its capacity of protein synthesis in the extracellular matrix. Under hypoxic ischemic conditions, followed by myocardial infarction, the fibroblast switches phenotype and transdifferentiate into myofibroblast, contributing to the healing by secreting extracellular matrix proteins and collagen deposition, with subsequent cardiac remodeling and regulation of the micro-environment metabolism.

Gestational diabetes - modern management and therapeutic approach (Review).

Gestational diabetes mellitus is an important healthcare problem with serious implications both to the mother and to the foetus. The necessity of clear screening criteria for the pregnant woman and also identifying from an early stage the risk groups can be beneficial instruments for better management of gestational diabetes. The present report identify the main screening criteria for patients at risk for gestational diabetes and the therapeutic-nutritional therapy for women that have gestational diabetes. The different diagnostic criteria, as well as the new instruments through which these criteria can be applied, are still heterogeneous, and it is necessary to unify and promote them. The prevalence of gestational diabetes has significantly increased in recent years, and this has led to an increase in the direct and indirect costs of healthcare. Establishing the optimal time and initiating the correct treatment is critical to achieving glycemic control and to minimize the impact on fetal development and perinatal complications.

Endometrial stromal sarcoma in a 27-year-old woman. Case report and literature review.

Endometrial stromal tumors are very rare, representing approximately 0.2% of uterine malignancies, having an incidence of one to two from a million of women. The diagnosis cannot be established by imaging, it is histopathological only, often necessitate supplementary immunohistochemistry tests. We report the case of a 27-year-old woman who had an initial diagnosis, in another hospital, of uterine adenomyoma, established by dilatation and uterine curettage and then by subsequently histopathological exam. This diagnosis led to an initial non-oncological surgery, with interannexial total hysterectomy. The establishment of the final histopathological diagnosis of stromal endometrial sarcoma has led to a serious reassessment of the case. Making a review of the literature, we found very few cases of endometrial stromal sarcoma in young women less than 30 years old and we have not identified any clear strategy of treatment. However, from precautionary and considering that may be at risk, even with very few cases reported, the distance metastases can be present, sometimes at large intervals of time, we decided, for oncological safety, reintervention after one month. At the second surgery, it was practiced bilateral salpingo-ovarectomy, cardinal ligaments excision, partial omentectomy, bilateral pelvic lymphadenectomy extended lumbo-aortic and interaortico-cava, sampling biopsy from the inguinal femoral adenopathy and re-excision of the vaginal vault. The evolution was favorable, the patient being follow-up together with the oncologist specialist.

Clinical and morphological correlations in early diagnosis of endometrial cancer.

The prevalence of endometrial cancer among asymptomatic women is rather reduced also due to the absence of a cost-efficient test, as there are no ideal screening examinations for endometrial cancer. Several methods were proposed in medical practice to discover endometrial neoplasia at an early stage, among which: endometrial biopsy, endovaginal ultrasound, targeted biopsy hysteroscopy. This study was made on a group of 38 patients monitored for metrorrhagia in the interval between July 1, 2014-July 1, 2016. All patients were monitored clinically and by ultrasound, endometrium samples were taken by biopsied uterine curettage, and a histopathological examination was performed, completed by immunomarking, whenever necessary. The clinical and paraclinical methods allowed for the creation of a protocol by which patients were monitored. This protocol allowed for the modulation and effectiveness of the treatment, establishing the best therapeutic conduct and the remote supervision.

Antenatal diagnosis and prognostic factors of aneurysmal malformation of the vein of Galen: A case report and literature review.

RATIONALE: Vein of Galen aneurysmal malformation (VGAM) is a rare complex malformation of the cerebral vascular system consisting of arteriovenous shunts between the vein of Galen and the cerebral arteries. PATIENT CONCERNS: We present the case of a 31-year-old pregnant woman, para 1, gravida 1. DIAGNOSES: At 26 weeks' gestation who was examined for an anechoic mass on the cerebral median midline with color and pulsed Doppler. She presented with positive flow on the color and pulsed Doppler test, associated with hydrocephalus, cortical hypoplasia, cardiomegaly, jugular vein distension. INTERVENTIONS: No intervention for VGAM was done. OUTCOMES: This case of a VGAM was associated with negative prognostic factors. LESSONS: The ultrasound color Doppler together with the 3D power Doppler allowed reconstruction of the vascular connections and of the relationship of these with other anatomical structures, which contributed to establishing the prognosis.
