RESUMEN
Background and Objectives: The objective of this study was to assess the effectiveness of using a peri-cervical tourniquet in reducing blood loss during a laparoscopic myomectomy. Materials and Methods: This prospective study evaluated the impact of performing a concomitant tourniquet placement during a laparoscopic myomectomy (LM). A total of 60 patients were randomly allocated to one of two groups: 30 patients who underwent an LM with a tourniquet placement (the TLM group) and 30 patients who benefited from a standard LM (the SLM group). This study's main objective was to evaluate the impact of tourniquet use on perioperative blood loss, which is quantified as the difference in the pre- and postoperative hemoglobin levels (Delta Hb) and the postoperative blood transfusion rate. Results: The mean Delta Hb was statistically lower in the TLM group compared to the SLM group: 1.38 g/dL vs. 2.41 g/dL (p < 0.001). The rate of postoperative iron perfusion in the TLM group was significantly lower compared to the SLM group (4 vs. 13 patients; p = 0.02). All four patients that required a blood transfusion were from the SLM group. On average, the peri-cervical tourniquet fastening time was 10.62 min (between 7 and 15 min), with no significant impact on the overall operative time: 98.50 min for the TLM group compared to 94.66 min for the SLM group. Conclusions: Fastening a tourniquet during a laparoscopic myomectomy is a valuable technique to effectively control intraoperative bleeding and enhance surgical outcomes.

STUDY OBJECTIVE: To present a case of a cesarean scar ectopic pregnancy treated by laparoscopic resection followed by isthmocele repair. DESIGN: A case report. SETTINGS: The University Gynecology Clinic of the Emergency Clinical City Hospital TimiÈoara, TimiÈoara, România. BACKGROUND: Cesarean scar pregnancy is a rare form of ectopic pregnancy. In recent years, its prevalence has risen because of the increasing number of cesarean sections. An early diagnosis can lead to early management, decreasing the risk of life-threatening complications such as uterine rupture and massive hemorrhage. Many therapeutic options are available, medical and surgical, but the current literature suggests that the laparoscopic approach with ectopic pregnancy resection is the best option. CASE REPORT: We present the case of a 30-year-old woman with a previous cesarean section in 2012 who was diagnosed by transvaginal ultrasound with a 6-week live pregnancy implanted at the level of the cesarean scar. The initial management was the administration of a 2-dose methotrexate protocol, but after 72 hours the transvaginal ultrasound showed an embryo with cardiac activity still present associated with an increased beta human chorionic gonadotropin level. We decided on laparoscopic surgical treatment, aiming to extract the pregnancy and repair the scar defect. A similar case was presented by Mahgoub et al [1], but their case had a different evolution, with decreasing levels of hCG. INTERVENTIONS: In order to reduce the blood loss, the anterior trunks of the hypogastric arteries were clipped. The side wall peritoneum was cut bilaterally, and the ureters and the hypogastric arteries were dissected. Next, we performed the dissection of the vesicouterine space. Because of the previous cesarean section, the identification of the correct dissection plane was difficult. A uterine manipulator was used to facilitate the dissection. The exact location of the gestational sac was demonstrated using intraoperative transvaginal ultrasound. To reduce the bleeding, Glypressin (Ferring GmbH, Saint Prex, Switzerland) was injected at the level of the uterine scar. The cesarean scar was cut using a monopolar knife. The gestation sac was reached easily and then extracted from the abdominal cavity with the use of an endobag. In order to obtain proper healing, the margins of the scar were resected using cold scissors. The hysterotomy was closed using a double-layered suture with 2.0 Vicryl (Ethicon Inc., Cincinnati, OH). We used methylene blue to verify the tightness of the suture. The final step was the removal of the clips. MEASUREMENTS AND MAIN RESULTS: The operative time was 85 minutes with minimal blood loss of about 20 mL. The patient recovered well and was discharged 2 days after the procedure. A transvaginal ultrasound was performed 1 month after the surgery showing good healing of the anterior uterine wall. CONCLUSION: The laparoscopic approach with excision and repair of the uterine wall represents a safe and efficient therapeutic option for the treatment of the cesarean scar ectopic pregnancy.

STUDY OBJECTIVE: To present a case of uterine prolapse in a pregnant patient at 10 weeks of gestation who was successfully treated by laparoscopic promontohysteropexy. To our knowledge, this is the first case of laparoscopic promontopexy during pregnancy to be reported in the literature. DESIGN: Step-by-step description of the surgery using videos (Canadian Task Force classification 3). SETTING: Uterine prolapse is a rare condition in young patients and is extremely rare in pregnant women. The reported incidence of uterine prolapse during pregnancy is 1/10,000 to 15,000 deliveries [1]. To date, only a few cases of prolapse during pregnancy have reported in the literature, most of which were treated with pessary insertion. A case involving laparoscopic surgery for uterine prolapse during pregnancy was reported by Matsumoto et al 1999 [2], but the authors did not perform the promontohysteropexy technique. INTERVENTION: A 27-year-old patient with uterine prolapse at 10 weeks of gestation was referred to our clinic for severe pelvic pain. Conservative treatment with pessary insertion was attempted but failed. Consequently, the patient was scheduled for laparoscopic promontohysteropexy. The surgery was made difficult by the increased size and softness of the uterus. To create an adequate surgical field, the sigmoid colon and right adnexa were suspended at the abdominal wall. The peritoneum above the promontorium was incised, and the longitudinal ligament was dissected. The paravesical spaces were opened, and the vesicovaginal space was dissected. A polypropylene mesh in the shape of an inverted "T" was introduced. The small arm was sutured to the anterior vaginal wall, and the posterior arms were passed through the posterior leaves of the broad ligament and fixed to the cervix at the level of the uterosacral ligaments. Both posterior arms were fixed at the level of the promontory using the Protack device (Medtronic, Minneapolis, MN). The mesh was completely covered with peritoneum. The patient was discharged 3 days after surgery, with no pain and with normal pelvic floor status. The pregnancy proceeded uneventfully, and she delivered a 3500-g healthy baby by scheduled cesarean section at 39 weeks of gestation. During surgery, the position of the mesh around the uterus was assessed. The mesh was completely covered with peritoneum, and there were no adhesions due to mesh insertion. At 6 months after delivery, pelvic floor status was reassessed and found to be normal. Written informed consent for reporting this case was obtained from the patient before the procedure. The procedure was performed in accordance with the ethical standards laid down in the 1964 Declaration of Helsinki and its later amendments. The Institutional Review Board and Ethical Committee of Victor Babes University of Medicine and Pharmacy ruled that approval was not required for this study. CONCLUSION: Laparoscopic promontohysteropxy can be performed during pregnancy if conservative treatment, such as pessary insertion, fails to restore the normal pelvic floor status.

OBJECTIVE: To investigate if early pregnancy serum neopterin concentrations (EPSN) could predict spontaneous preterm birth (SPB). METHODS: EPSN was measured in 92 sera collected from 46 pregnant women with birth at term and 40 sera from 20 pregnant women with preterm birth. Two sera were collected for each case: in the first and early second trimester. RESULTS: EPSN concentrations correlate with gestational age (ρ=0.275, P=0.001), a correlation which was present in both groups: term and preterm birth. EPSN were higher in pregnancies with SPB compared with normal pregnancies (6.27±1.03 vs. 6.04±0.15, P=0.039). Patients with SPB showed a considerable increase of EPSN in the second trimester compared with patients with birth at term (7.30±1.53 vs. 6.16±0.23, P=0.043). A sharper increase was found in the group with SPB before 32 weeks of pregnancy (wp) (9.83±4.36 vs. 6.16±0.23, P=0.016). Pregnant women with an early second trimester serum neopterin value of above 8 nmol/L are associated with a risk of SPB before 32 wp (odds ratio=14.4, P=0.01) and of SPB before 34 wp (odds ratio=3.6, P=0.05), respectively. CONCLUSIONS: EPSN increases with the gestational age and predicts SPB in asymptomatic pregnant women.

BACKGROUND: Persistent infections with high risk human papillomaviruses (HR-HPV) cause virtually all cervical cancers. METHODS: An observational study was conducted aiming to estimate the rate of HPV infection persistence after LEEP in patients with high grade squamous intraepithelial lesions (HSIL). Moreover, the study investigated if persistence is age related. For this reason a total of 110 patients were included between January 2010 and June 2015. RESULTS: At 6 months after LEEP the overall HPV infection persistence rate was 40.9 %, at 12 months 20 % and at 18 months 11.8 %. Type 16 showed the highest persistence rate: 27.3 % at 6 months, 12.7 % at 12 months and 10 % at 18 months after LEEP. The persistence for HPV type 16 at 6 months after LEEP was significantly higher in the group > =36.5 years old compared to the persistence rate in the group <36.5 years old (p = 0.0027, RR = 2.75, 95 %ϵ(1.34; 5.64)) (see Table 3). CONCLUSIONS: LEEP does not completely eradicate HPV infection. HPV persistence rate after LEEP is higher in infections with type 16 and in women older than 36.5 years.

Background. Persistent human papillomavirus (HPV) infection is a necessary event in cervical cancer tumorigenesis. Our objectives were to estimate the rate of HPV infection persistence after large loop excision of the transformation zone (LEEP) in patients with high grade squamous intraepithelial lesions (HSIL) and to investigate if HPV persistence is type related. Methods. We conducted a prospective study on 89 patients with HSIL treated with LEEP. DNA HPV was performed before surgery and at 6, 12, and 18 months after LEEP. Results. Four patients were excluded from the study. The HPV persistence in the remaining 85 patients was 32.95% (6 months), 14.12% (12 months), and 10.59% (18 months). Type 16 had the highest persistence rate, 23.5% (6 months), 11.8% (12 months), and 8.2% (18 months). Coinfection was found to be 54.12% before LEEP and 18.8% (6 months), 4.7% (12 months), and 3.5% (18 months) after LEEP. The rate of coinfections including type 16 was 46.83% of all coinfections. Coinfection including type 16 was not correlated with higher persistence rate compared to infection with type 16 only. Conclusions. HPV infection is not completely eradicated by LEEP in patients with HSIL lesion on PAP smear. HPV persistence after LEEP is influenced by HPV type. HPV type 16 has the highest persistence rate.
RESUMEN
STUDY OBJECTIVE: The objective of this systematic review is to investigate the impact of laparoscopic myomectomy techniques on pregnancy outcomes, with a specific focus on the correlation between the type of suture used during the procedure and the incidence of uterine rupture. Additionally, the study aims to examine how the localization and size of myomas, key factors in laparoscopic myomectomy, may influence fertility outcomes. DATA SOURCES: extensive searches were conducted using MDPI, PubMed, Web of Science, and Cochrane Library databases from 2008 to November 2023. METHODS OF STUDY SELECTION: The study involved women of reproductive age diagnosed with fibroids who underwent surgical removal of fibroids using either laparotomy or laparoscopy. The evaluation of pregnancy outcomes focused on indicators such as live birth rates, miscarriage rates, stillbirth rates, premature delivery rates, and cases of uterine rupture. Quality assessment was systematically performed by employing the National Institutes of Health Study Quality Assessment Tools, with the subsequent formulation of clinical recommendations that were meticulously graded in accordance with the robustness of the underlying evidence. RESULTS: The pregnancy outcomes post-myoma treatment, as reflected in one of the presented tables, show a promising number of pregnancies and live births, but also indicate the potential risks of miscarriages and preterm births. The diversity in outcomes observed among various studies underscores the imperative for tailored patient care, as well as the necessity for additional research aimed at optimizing fertility and pregnancy outcomes following myoma treatment. CONCLUSION: This study offers insights into the criteria for patient selection and intraoperative methodologies specifically related to laparoscopic myomectomy. To enhance our understanding of the associations between fibroid characteristics (location, size) and reproductive outcomes, additional research is warranted, particularly through well-designed clinical trials.
RESUMEN
Introduction: Uterine leiomyomas are common benign pelvic tumors. Currently, laparoscopic myomectomy (LM) is the preferred treatment option for women in the fertile age group with symptomatic myomas. The authors hypothesize that combining LM with a bilateral temporary occlusion of the hypogastric artery (TOHA) using vascular clips minimizes uterine blood flow during surgery and can significantly reduce surgery-associated blood loss. Materials and methods: This single-center, prospective randomized study was conducted at the Department of Obstetrics and Gynecology, Municipal Emergency Clinical Hospital Timisoara, Romania. Patients aged between 18 and 49 who preferred laparoscopic myomectomy and wished to preserve fertility were included, provided they had intramural uterine leiomyomas larger than 4 cm in diameter that deformed the uterine cavity. The study analyzed data from 60 laparoscopic myomectomies performed by a single surgeon between January 2018 and December 2020. Patients were randomly assigned to either: "LM + TOHA" group (29 patients), and "LM" group (31 patients). The study's main objective was to evaluate the impact of TOHA on perioperative blood loss, expressed as mean differences in Hb (delta Hb). Results: Delta Hb was statistically lower in the "LM + TOHA" group compared to "LM" group, with mean ± standard (min-max): 1.68 ± 0.67 (0.39-3.99) vs. 2.63 ± 1.06 (0.83-4.92) g/dL, respectively (p < 0.001). There was a statistically significant higher need for postoperative iron perfusion in the "LM" group, specifically 0 vs. 12 patients (p < 0.001), and lower postoperative anemia in "LM + TOHA" group (p < 0.001). Necessary artery clipping time was 10.62 ± 2.47 (7-15) minutes, with no significant impact on overall operative time: 110.2 ± 13.65 vs. 106.3 ± 16.48 (p = 0.21). There was no difference in the length of hospitalization or 12-month post-intervention fertility. Discussion: Performing bilateral TOHA prior to laparoscopic myomectomy has proven to be a valuable technique in reducing surgery-associated blood loss, while minimizing complications during surgery, with no significant increase in the overall operative time. Clinical trial registration: ISRCTN registry, (www.isrctn.com), identifier ISRCTN66897343.
RESUMEN
An isthmocele, also known as a caesarean scar defect, is a long-term complication of caesarean sections with an increasing incidence. Although is often asymptomatic, it is a novel recognised cause of abnormal uterine bleeding, and it is a major risk factor for caesarean scar pregnancies or uterine ruptures in subsequent pregnancies. Currently there are no guidelines for the diagnosis and management of this condition. Several surgical techniques for the correction of isthmocele are proposed, including laparoscopic excision, vaginal repair, a combined laparoscopic-vaginal approach or more recently hysteroscopic resection. We present the case of a GII PI, 29 years old patient with a previous c-section who presented in our clinic with a positive pregnancy test for pregnancy confirmation. The ultrasound examination revealed an intrauterine evolutive 8 weeks pregnancy and a caesarean scar defect. After counselling the patient opted for pregnancy continuation and laparoscopic correction of the isthmocele. The surgery was performed under ultrasound guidance. The defect was resected, and the uterus was closed with a continuous two-layer suture. No intraoperative or postoperative complications were present. The pregnancy continued uneventfully A caesarean section was performed at term revealing a fully healed scar.
RESUMEN
We report the case of a 29-year-old patient with low-grade squamous intraepithelial lesion (L-SIL), negative human papilloma virus (HPV), positive p16/Ki-67 dual-staining and colposcopy suggestive for severe dysplastic lesion. The patient underwent a loop electrosurgical excision procedure (LEEP), the pathology report revealing mesonephric hyperplasia and adenocarcinoma. The patient also opted for non-standard fertility-sparing treatment. The trachelectomy pathology report described a zone of hyperplasia at the limit of resection towards the uterine isthmus. Two supplementary interpretations of the slides and immunohistochemistry (IHC) were performed. The results supported the diagnosis of mesonephric adenocarcinoma, although with difficulty in differentiating it from mesonephric hyperplasia. Given the discordant pathology results that were inconclusive in establishing a precise diagnosis of the lesion and the state of the limits of resection, the patient was referred to a specialist abroad. Furthermore, the additional interpretation of the slides and IHC were performed, the results suggesting a clear cell carcinoma. The positive p16/Ki-67 dual-staining prior to LEEP, the non-specific IHC and the difficulties in establishing a diagnosis made the case interesting. Given the limitations of cytology and the fact that these variants are independent of HPV infection, dual staining p16/Ki-67 could potentially become useful in the diagnosis of rare adenocarcinoma variants of the cervix, however further documentation is required.
RESUMEN
Patients diagnosed with low-grade squamous intraepithelial lesion ((L-SIL) or atypical squamous cells of undetermined significance (ASC-US) are subjected to additional investigations, such as colposcopy and biopsy, to rule out cervical intraepithelial neoplasia 2+ (CIN 2+). Especially in young patients, lesions tend to regress spontaneously, and many human papilloma virus (HPV) infections are transient. Dual-staining p16/Ki-67 has been proposed for the triage of patients with ASC-US or L-SIL, but no prospective study addressing only this subgroup of patients has been conducted so far. We performed a prospective study including all eligible patients referred for a loop electrosurgical excision procedure (LEEP) in the Department of Obstetrics and Gynecology of TimiÈoara University City Hospital. HPV genotyping and dual-staining for p16/Ki-67 were performed prior to LEEP, at 6 and 12 months after LEEP. A total of 60 patients were included in the study and completed the follow-up evaluation. We analyzed the sensitivity and specificity for biopsy-confirmed CIN2+ using the 95% confidence interval (CI) of high-risk human papilloma virus (HR-HPV), dual-staining p16/Ki-67, colposcopy, and combinations of the tests on all patients and separately for the ASC-US and L-SIL groups. Dual-staining p16/Ki-67 alone or in combination with HR-HPV and/or colposcopy showed a higher specificity that HR-HPV and/or colposcopy for the diagnosis of biopsy confirmed CIN2+ in patients under 30 years. Colposcopy + p16/Ki-67 and HR-HPV + colposcopy + p16/Ki-67 showed the highest specificity in our study.
RESUMEN
The objective of our paper is to underline the importance of assessing microarray genetic analysis for the detection of chromosomal abnormalities in rare cases such as left atrial isomerism, mostly in the context of antenatally detected syndromes. We present the case of a 26-year-old primipara, at 26 weeks of gestation, with prior first trimester normal anomaly scan, who presented in our department accusing lower abdominal pain. An anomaly ultrasound examination of the fetus revealed cardiomegaly with increased size of the right atrium, non-visualization of the atrial septum or the foramen ovale, malalignment of the three-vessel view, location of the superior vena cava above the two-vessel view, slight pericardial effusion, and no interruption of the inferior vena cava nor presence of azygos vein being noted. Associated extracardiac abnormalities, such as small kidneys at the level of the iliac fossa, micrognathia, dolichocephaly with hypoplasia of the cerebellum, increased nuchal fold, and reduced fetal movements were also reported. A diagnostic amniocentesis was performed, and, while the conventional rapid prenatal diagnostic test of the multiplex quantitative fluorescent polymerase chain reaction (PCR) came as normal, the microarray analysis (ChAS, NCBI Built 37 hg 19, detection of microdeletions or microduplications larger than 100 kb) revealed two chromosomal abnormalities: a 22.84 Mb loss of genetic material in the 18q21.31-18q23 chromosomal region and a gain of 22.31 Mb of genetic material in the 20p13-20p11.21 chromosomal region. After the termination of pregnancy, a necropsy of the fetus was performed, confirming heterotaxy syndrome with a common atrium, no atrial septum, superior vena cava draining medianly, and pulmonary veins that drained into the lower segment of the left atrium due to an anatomically enlarged single common atrium. The extracardiac findings consisted of two bilobar lungs, dysmorphic facies, low-set ears, nuchal fold edema, and small kidneys located in the iliac fossa. These findings are conclusive evidence that left atrial isomerism is a more complex syndrome. The genetic tests of the parents did not reveal any translocations of chromosomes 18 and 20 when the Fluorescent in situ Hybridization (FISH) analysis was assessed. The antenatal detection of corroboration between different structural abnormalities using serial ultrasound examinations and cardiac abnormalities, together with the detection of the affected chromosomes, improves the genetic counseling regarding the prognosis of the fetus and the recurrence rate of the condition for siblings.

Due to a high rate of transient human papillomavirus (HPV) infection, HPV genotyping has a low specificity for high-grade cervical lesions, especially in young women. p16/Ki-67 dual immunocytochemical staining can also be used for the detection of oncogenic changes in cervical cells. Our aim was to compare the performance of p16/Ki-67 dual staining and HPV genotyping in the detection of high-grade cervical lesions in patients with atypical squamous cells of undetermined significance (ASCUS)/low-grade squamous intraepithelial lesion (LSIL) on Pap smear. We retrospectively analyzed 310 patients with ASCUS/LSIL on Pap smear, who underwent colposcopy. Among these, 161 patients with suspected lesions detected by colposcopy were referred for biopsy. HPV genotyping by LINEAR ARRAY HPV Genotyping Test (CE-IVD) and p16/Ki-67 dual staining by CINtec PLUS Cytology kit was performed prior to cervical biopsy. The overall sensitivity and specificity of HPV genotyping for the detection of cervical intraepithelial neoplasia (CIN) 2-3 was 79% and 72%, respectively in patients with ASCUS, and 85% and 64%, respectively in patients with LSIL. For p16/Ki-67 test, sensitivity and specificity rate was 66% and 93%, respectively in ASCUS and 59% and 79%, respectively in LSIL group. The specificity of p16/Ki-67 staining was significantly higher in both groups in patients aged <30 years compared to patients >30 years old (p < 0.001). Our results showed that p16/Ki-67 dual staining has a higher specificity compared to HPV genotyping, especially in patients under 30 years old. This indicates the usefulness of p16/Ki-67 testing in the triage of patients with ASCUS/LSIL and <30 years old, prior to referral for colposcopy and biopsy.

p16÷Ki-67 dual-stained cytology, either alone or combined with human papillomavirus (HPV) 16÷18 genotyping, could be a useful tool for triage for colposcopy of HPV-positive patients. Based on this background, we aimed at comparing the diagnostic performance of the p16÷Ki-67 dual staining test, and high-risk HPV test for the detection of high-risk cervical intraepithelial neoplasia (CIN2÷3) in patients diagnosed with low-grade squamous intraepithelial lesion (LSIL) on Pap smear. We performed a retrospective study including 184 patients with LSIL cytology on Pap smear, of which 64 were referred for biopsy after colposcopy. Prior biopsy HPV genotyping and dual staining test were performed on all 64 patients. The mean age of the patients selected for conization was 36 years and seven months. The pathological exam showed that 28.13% (18÷64) from the patients LSIL on cytology were actually having CIN2÷3: 12 cases with CIN2, five cases with CIN3 and one case of in situ cervical carcinoma. HPV positive were 56.25% (36÷64) of the patients with LSIL. The p16÷Ki-67 dual staining test was positive in 29.69% (19÷64) of the patients with LSIL. Among women with LSIL cytology, the sensitivity and specificity of the HPV genotyping test for predicting CIN2÷CIN3 were 94.44% (17÷18) and 58.7% (27÷46), respectively. The sensitivity and specificity of the p16÷Ki-67 dual staining test were 66.67% (12÷18) and 84.78% (39÷46), respectively. Our results agree with other data available in literature and suggest that the p16÷Ki-67 dual staining test could be included in the management protocol of patients with modified cytology as a triage test before referring those patients for colposcopy.

Despite the implementation of various screening programs in many countries, cervical cancer continues to be a major health problem. Cervical cytology is the most used screening method, but human papillomavirus (HPV) genotyping, alone or in combination with cytology, has gained ground during the last years. Still, one of the major limitations of HPV-genotyping is the low specificity of HPV as a screening method in young women that are HPV-positive, but with no potential for future disease. Obviously, there is a need for a better screening algorithm. The ideal screening test for cervical high-grade lesions should detect the effect of high-risk (HR)-HPV infection after cell transformation, but not before, and should accurately identify the cases that are more likely to experience disease progression to neoplasia. Solid data regarding the benefit of immunocytochemistry in the evaluation of the patients with modified cervical cytology have been published recently. The use of the dual staining with p16INK4a and Ki-67 could increase specificity of the method for the detection of atypical cells and may perform better in predicting the risk of high-grade dysplasia in the near future.

Vasa praevia is a rare but very dangerous obstetrical condition. The purpose of our article is to evaluate data available in literature that indicate in vitro fertilization as a risk factor for vasa praevia. PubMed Library and Cochrane Database were searched using the keywords vasa praevia, in vitro fertilization, velamentous cord insertion, placenta praevia. The conditions related to in vitro fertilization that increase the risk of vasa praevia formation were identified and discussed. Also, the diagnosis and management options were reviewed. In vitro fertilization represents a risk factor for vasa praevia and all such pregnancies should be screened by transvaginal ultrasound for vasa praevia.

Umbilical cord knot (UCK) affects around 1% of pregnancies and tightening of UCK is a very rare and highly unpredictable complication of pregnancy that can lead to fetal demise or neonatal death. The majority of authors agree that very little could be done to prevent fetal deaths in pregnancies with undiagnosed tight UCK. We herein report the case of a 39-year-old, gravidity five, parity three, pregnant woman at 40 weeks and five days age of pregnancy, whose pregnancy evolved without complications and who was admitted to hospital for the management of the birth. Although the last ultrasound examination before birth showed a reversible arterial redistribution in the fetus dependent on the postural status of the pregnant women and other factors associated with umbilical cord knot were present, the diagnosis was missed because of the factors' non-specificity. After a spontaneous labor without complications a dead male fetus, weight 3300 g, without heartbeat, Apgar score 0 was delivered. Macroscopic and microscopic findings confirmed that the cause of neonatal death was asphyxia caused by a tight UCK. The aim of our paper is to present the dramatic outcome of a pregnancy with a fetus with a tight umbilical cord knot (UCK), to bring to attention the signs that suggested the diagnosis, and to review the literature on this subject.

Only a few studies in the literature have reported the contribution of endothelial progenitor cells (EPCs) in ovarian tumors, and with regard to malignant tumors, the data on the pre-existing endothelium insertion rate and the extent to which these cells contribute to tumor angiogenesis is controversial. The present study demonstrated the existence of EPCs and evaluated the expression of two markers, AC133 (also known as cluster of differentiation 133 or prominin) and tyrosine kinase with immunoglobulin-like and EGF-like domains 2 (Tie2), signaling the presence of EPCs in the pre-existing endothelium. In total, 62 female patients who were diagnosed with ovarian tumors were retrospectively selected over a four-year period. Immunohistochemical analyses used Tie2 and AC133 as primary antibodies. In total, 27.4% of ovarian tumor cases expressed AC133 and Tie2 in blood vessel endothelial cells. The expression of these two markers did not correlate with the clinicopathological prognostic parameters, histological type, vascular microdensity or vessel type. The expression of AC133 and Tie2 in blood vessel endothelial cells contributes to angiogenesis progression in cases where the budding process is reduced or absent, as shown by the inverse correlation with the rate of proliferation of the endothelial cells.
