Application of narrow-band imaging combined with hysteroscopic 7Fr cold knife in the treatment of missed early miscarriage.

The application of narrow-band imaging for missed early miscarriage treatment remains unclear. This study determined the application advantages of NBI combined with hysteroscopic 7Fr cold knife embryo removal for treating missed early miscarriage. A retrospective selection of 208 patients who were hospitalized for missed early miscarriage at Hubei Provincial Maternal and Child Health Hospital from January 2023 to June 2023 were included. The patients were divided into three groups according to the treatment methods: Group A (medical abortion), Group B (NBI combined with hysteroscopic 7Fr cold knife), and Group C (ultrasound-guided vacuum aspiration). The clinical data of the three groups were analyzed, and endometrial recovery after treatment was compared to identify risk factors affecting complications after treatment for missed early miscarriage. The endometrial thickness was greatest in Group A and thinnest in Group C two weeks post-treatment. Group B had the earliest menstrual recovery and the lowest intrauterine residual and intrauterine adhesion incidences. The pregnancy termination method was the only independent risk factor for intrauterine adhesions after treatment. The time to menstrual recovery after treatment, the serum beta-human chorionic gonadotropin level at 2weeks post-treatment, and the endometrial thickness had predictive value for intrauterine retention. The combined prediction of the above indicators showed high accuracy. The use of NBI combined with hysteroscopic 7Fr cold knife embryo removal in patients with missed early miscarriage results in a lower risk of intrauterine residuals and IUA than ultrasound-guided vacuum aspiration and medical abortion. This approach leads to earlier menstrual recovery and protects the endometrium.

Retroperitoneal ectopic pregnancy from a tertiary obstetrics hospital in Vietnam: A case series and literature review.

Retroperitoneal ectopic pregnancy is an uncommon condition in clinical practice, often associated with misdiagnosis and unconventional treatment. Delayed interventions can lead to poor prognosis and sometimes catastrophic situations. Due to the limited number of reported cases in the literature, an established treatment protocol has yet to be introduced. This case series presents three instances at a tertiary women's hospital in Vietnam. In cases 1 and 2, a single approach-either surgery or a chemo-regimen-was applied. However, the third patient was treated with a combination of both therapies. This series highlights an evolution in management, progressing from incomplete removal of the gestation to a comprehensive combination of surgery and chemotherapy. Additionally, high serum beta-human chorionic gonadotropin (β-hCG) levels and suspicious ultrasound and magnetic resonance imaging (MRI) findings are crucial for establishing the diagnosis.

Abortion in evolution, caesarean scar pregnancy, and cervical ectopic: discerning the triplets on ultrasound.

On the second day of my clinical observership in the Obgyn Department of the Vienna University Hospital, I saw a suspected case of caesarean scar pregnancy on follow-up, with one of my very senior professors, in the gynaecology outpatient clinic. The 29-year-old multigravida with a previous caesarean section had earlier presented to the emergency room with vaginal bleeding at 7 weeks of gestation. Ultrasound scan revealed a non-viable low-lying gestational sac located near the caesarean section scar, with a myometrial thickness of 0.96 cm. There was minimal vascular flow during the Doppler interrogation. Her quantitative serum beta-human chorionic gonadotropin was 687 IU/l at presentation. This had dropped to 344 IU/l after 48 h, with a further drop to 39 IU/l after a week. Repeat ultrasound scan 1 week after revealed an empty uterus with no visible gestational sac, and vaginal bleeding had resolved. My professor made a final diagnosis of a spontaneous complete abortion. On reflection, this experience further reinforced the diagnostic dilemma that many clinical conditions can present, the need for a high index of suspicion in diagnosing and differentiating clinical conditions that present similar features, as well as the need for younger clinicians to leverage the better knowledge and experience of more senior colleagues to unknot knotty clinical dilemmas.

The role of inflammatory markers and βhCG levels in predicting the success of single-dose methotrexate treatment in tubal ectopic pregnancy.

To evaluate the predictive ability of serum beta human chorionic gonadotropin (βhCG) levels and inflammatory markers derived from hemogram parameters in the success of methotrexate (MTX) treatment for tubal ectopic pregnancy. This retrospective study involved the examination of patients diagnosed with tubal ectopic pregnancy and treated with a single dose of MTX at our clinic between 2018 and 2023. The monocyte-to-lymphocyte ratio (MLR), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and systemic immune-inflammation index (SII) were calculated from blood samples taken at the time of presentation. βhCG levels were recorded on days 1, 4, and 7 of treatment. The patients were categorized into successful and unsuccessful treatment groups based on their response to MTX. No statistically significant differences were found between the two groups regarding MLR, NLR, PLR, or SII values (P = 0.284, P = 0.097, P = 0.455, and P = 0.061, respectively). In the receiver operating characteristic analysis of serum βhCG from day 1 to day 4, the area under the curve value was calculated as 0.832. The cutoff value for the serum βhCG change from days 1 to 4 was -0.093 (-9.3%), with a sensitivity of 85.53% and specificity of 74.14%, and a positive predictive value (PPV) of 87.5%. There were no significant differences in inflammatory markers (MLR, NLR, PLR, and SII) between the successful and unsuccessful MTX treatment groups. The change in serum βhCG levels between days 1 and 4 can be used as an early predictor of MTX treatment success in tubal ectopic pregnancy.

Ovarian Masses in Children: Surgical Experience and Outcomes.

This study aims to review our experience of treating ovarian masses in children with an emphasis on clinical presentation, diagnosis, treatment, and outcome. We retrospectively reviewed the electronic medical records of all patients below 18 years of age who underwent surgical treatment for ovarian masses at our institute between 2009 and 2023. Study variables included demography, clinical presentation, physical findings, tumor markers, radiologic features, operative details, histopathology, follow-up status, and overall survival. During the study period, 30 patients with a mean age of 10.07 years (range: 15 days-18 years) underwent surgical treatment for ovarian masses. Nonneoplastic ovarian masses were seen in 5 (16.7%) patients, whereas 25 (83.3%) patients had benign (10 [33.3%], borderline 3 [10%], or malignant 12 [40%]) ovarian neoplasms. The most common clinical presentation in the benign group was abdominal pain (n = 6), whereas painless abdominal mass (n = 6) was the predominant complaint in children with malignant tumors. A functional ovarian mass presenting with precocious puberty or virilization was seen in 5 (16.7%) patients. On imaging, nonneoplastic and benign lesions had a mean size of 4.33 (range: 3.1-6) cm and 12.63 (range: 2.8-28) cm, respectively, whereas borderline and malignant masses had a mean tumor size of 22.5 (range: 6.5-32) cm and 12.55 (range: 3.5-18.7) cm, respectively (P < 0.05). The cystic component was identified in all nonneoplastic and benign tumors, whereas the solid component was present in all borderline and malignant lesions (P < 0.05). Tumor markers such as serum alpha-fetoprotein and beta-human chorionic gonadotropin were raised in 8 (66.67%) of malignant tumors, whereas markers were normal in all benign lesions and borderline malignant lesions and 4 (33.33%) of malignant tumors. Lactate dehydrogenase (LDH) was also raised in all malignant masses (n = 12), whereas it was normal in all benign and borderline malignant masses (n = 18). In 6 (20%) patients with nonneoplastic and benign masses with maximum tumor size <6 cm, the laparoscopic approach was adopted, whereas open surgery was preferred in the rest of the patients. At a mean follow-up of 53.5 (range: 4-117) months, all patients are alive and disease free. Preoperative imaging characteristics (tumor size and solid component) and raised tumor markers may help us to differentiate between benign and malignant ovarian pathologies. The overall prognosis of pediatric ovarian tumors seems to be favorable.

Epithelioid trophoblastic tumor in male patients with germ cell tumor: A clinicopathologic analysis of five cases

Epithelioid trophoblastic tumor (ETT) is an extremely rare chorionic-type neoplasm in the testis, with only seven cases reported in the literature. Here, we report five cases of testicular ETT from a single institution, constituting the largest series of this rare tumor to date. The patients had a mean age of 44 years (range, 20–68 years). Four patients had a previous history of testicular germ cell tumor (GCT) treated with chemotherapy, and they developed ETT in metastatic sites in a mean of 11 years (range, 3–15 years) after the initial diagnosis of testicular GCT. Only one patient had ETT in the testis. Three patients had a normal serum beta–human chorionic gonadotropin (β-hCG) level, and two patients had a level that was slightly elevated, but far below that typically seen in patients with choriocarcinoma. ETT was characterized by a proliferation of intermediate trophoblastic cells with abundant eosinophilic cytoplasm, and the tumors frequently had coagulative necrosis with eosinophilic debris, mimicking keratinizing squamous cell carcinoma. The trophoblastic phenotype of ETT was supported by its immunoreactivity for trophoblastic markers, including GATA-3 (3 of 3 cases tested), α-inhibin (3/4), p63 (3/5), and β-hCG (3/4). ETT was also positive for cytokeratin (4/4) and GCT marker SALL4 (3/3). Despite surgery and chemotherapy, two patients died of disease 17 months after ETT diagnosis, and three patients were alive with metastatic disease at a mean of 20 months (range, 15–28 months). Our results demonstrate that ETT may be an aggressive disease associated with distinct pathologic features and poor clinical outcome.

Retroperitoneal Teratoma: A Rare Entity in a Young Infant

Abstract Background: Primary retroperitoneal teratoma of infancy is rare, comprising only 3.5%–4% of all germ cell tumors. The presentation may range from an asymptomatic mass to an abdominal lump causing symptoms due to mass effect on the neighbouring organs. We present a young infant with an abdominal mass who posed a diagnostic challenge. Clinical Description: A 3monthold female infant with an uneventful antenatal and perinatal history presented with complaints of abdominal distension since 1½ months of age. A lump was palpable involving the entire right side of the abdomen, crossing the midline. Management and Outcome: Despite detailed radiological imaging and trucut biopsy, the diagnosis was unclear. A complete open laparoscopic excision of the mass followed by a biopsy confirmed the diagnosis of grade 2/3 immature teratoma. Serum alphafetoprotein levels and betahuman chorionic gonadotropin levels were normal. Chemotherapy was not administered. The patient has been on followup for the past 2½ years, doing well without any complaints. Conclusion: Early recognition and complete excision of primary retroperitoneal teratoma with mature or partly immature histopathology carries a good prognosis.

AB039. Malignant transformation of intracranial germinoma to non-germinomatous germ cell tumors-incidence, treatment strategy and outcome: a case report and literature review.

Intracranial germ cell tumors are rare neoplasms seen mainly in children and adolescents. Compared to non-germinomatous germ cell tumors (NGGCTs), germinomas typically respond well to chemo-radiotherapy and portend a better prognosis. We report here a patient with intracranial germinoma which showed complete remission following chemo-radiotherapy but re-presented with malignant transformation to NGGCT thirteen years later. We then performed a literature review to understand the treatment strategy and outcome of this rare phenomenon. Review of the patient's case note, followed by a literature review of the topic. A 13-year-old male presented with 6 weeks of polyuria and polydipsia. Imaging showed bifocal (suprasellar and pineal) lesions. Histology from an open biopsy diagnosed a germinoma. He underwent extended whole ventricular irradiation with local boost and chemotherapy, which led to complete resolution on imaging. Thirteen years later, he re-presented with headaches and diabetes insipidus. Imaging showed a new right frontal lesion with elevated serum beta-human chorionic gonadotropin (β-hCG) and alpha-fetoprotein (AFP). The tumor was excised with histology confirming a mixed tumor comprising germinoma, yolk sac, and choriocarcinoma. A literature review returned eight case reports of malignant transformation of intracranial germinoma to NGGCTs, covering eight patients (seven males, and one female; aged 5-23 years old). Four had the primary tumor located in the pineal region, three in the suprasellar region, and one at both sites. Recurrence with malignant transformation occurred at a median of 24.5 months after initial diagnosis (range, 5 months to 14 years). Five patients had recurrences intra-abdominally, all of whom had a ventriculoperitoneal shunt (VPS) inserted during the treatment of the initial tumor. Of the remaining three intracranial recurrences, two were at the same site while one at a distant site. The most common histology was yolk sac tumor (five patients), followed by two each of immature teratoma, choriocarcinoma, and embryonal carcinoma (some were mixed germ cell tumors). Of those with intra-abdominal recurrence, four died within 2 months of diagnosis. Those with intracranial recurrences survived longer, with a median survival of 15 months, and one longer than 27 months. Malignant transformation to NGGCTs is rare. Relapse can occur intracranially, or in cases where VPS was present, intraabdominally. Outcomes following transformation were poor despite aggressive treatment, with those intra-abdominal recurrences faring much worse.

Predicting the Outcomes of In Vitro Fertilization Using Baseline Maternal Serum Inflammatory Markers: A Retrospective Cohort Study.

Achieving pregnancy through in vitro fertilization (IVF) remains a challenge, with less than one-third of women succeeding. There is a pressing need for reliable predictive tools to assess the likelihood of post-IVF pregnancy. While some serum inflammatory biomarkers have been investigated for their predictive potential, substantial knowledge gaps persist. This study examined the utility of different inflammatory markers in predicting IVF outcomes. Inflammatory markers including the white blood cell count, neutrophil-to-lymphocyte ratio (NLR), platelet count, mean platelet volume, platelet distribution width, platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), erythrocyte sedimentation rate, and vitamin D3 were assessed. Study outcomes were chemical pregnancy (positive serum beta-human chorionic gonadotropin 2 weeks post-embryo transfer), clinical pregnancy (detection of pregnancy sac via transvaginal ultrasonography), and viable pregnancy (detection of fetal heart rate). Univariate and multivariate logistic regression analyses were conducted, with multivariate analysis incorporating age, body mass index, infertility duration, type, and etiology, as well as all studied serum inflammatory markers, embryo count, stage, quality, and endometrial thickness. Lower NLR (p<0.001, odds ratio [OR]=0.372 [0.247-0.559]) and CRP (p=0.035, odds ratio=0.956 [0.916-0.997]) predicted chemical pregnancy in univariate analysis, with NLR maintaining significance in multivariate analysis (p=0.022, OR=0.319 [0.120-0.848]). Lower NLR (p<0.001, OR=0.309 [0.198-0.482]) and PLR (p=0.013, OR =0.994 [0.990-0.999]) predicted clinical pregnancy, with NLR surviving multivariate analysis (p=0.005, OR = 0.217 [0.075-0.626]). Lower NLR (p<0.001, OR = 0.320 [0.198-0.516]) also predicted viable pregnancy, maintaining statistical significance in multivariate analysis (p = 0.002, OR = 0.177 [0.058-0.541]). Other studied inflammatory markers did not predict IVF outcomes. NLR emerged as a robust independent predictor of pregnancy attainment after IVF.

GCT-21. MULTINATIONAL ANALYSIS OF PEDIATRIC RELAPSED/REFRACTORY CENTRAL NERVOUS SYSTEM NON-GERMINOMATOUS GERM CELL TUMORS

Abstract BACKGROUND Patients with relapsed/refractory central nervous system (CNS) non-germinomatous germ cell tumors (NGGCTs) have poor prognosis. We explored prognostic factors to guide the management of these patients. METHODS We performed a multinational retrospective study of relapsed/refractory CNS NGGCTs. Data were summarized using standard descriptive statistics. Overall survival (OS) was evaluated using Kaplan-Meier and Fisher’s exact test to estimate odds ratios (OR) and 95% confidence intervals (CI). RESULTS We identified 31 patients from eight centers. The median age at initial diagnosis was 11 years (interquartile range (IQR): 9-15.3). Twenty patients (64.5%) suffered a relapse, and 11 patients (35.5%) had refractory disease. The median follow-up time since relapse/progression was 17.5 months (range:1-295). The median time to relapse/progression was 12.1 months (IQR: 5.5-27.5). Ten patients (32.3%) received high-dose chemotherapy (HDCx) with stem cell rescue. Sixteen patients (51.6%) received re-irradiation at relapse/progression. Nine patients (29%) achieved complete remission (CR). Ten patients (32.3%) were alive at the time of the last follow-up. Among the ten survivors, the median serum and cerebrospinal fluid (CSF) alpha-fetoprotein levels were 2.3 ng/dl (range: 0-17) and 2.1 ng/dl (range: 0-55), respectively, the median serum and CSF beta-human chorionic gonadotropin were 23 IU/L (0-168) and 139 IU/L(0-601), none underwent gross total resection, eight received HDCx, and seven received radiotherapy (craniospinal irradiation (n=6), abdominal radiotherapy (n=1)). HDCx (OR=19.8, 95%CI: 2.7-145.7; p=0.01) and achieving CR at the end of relapse treatment (OR=160, 95%CI: 8.9-2880.5; p=&amp;lt;0.001) were associated with a survival benefit. Re-irradiation (OR=3.3 95%CI: 0.53-20.9; p=0.24) was not associated with a survival benefit. CONCLUSIONS A subset of patients with relapsed NGGCTs are salvageable at relapse. HDCx and achieving CR at the end of relapse therapy were associated with a survival benefit. More studies are required to identify these patients who would benefit from salvage therapy.

Comparing the effectiveness of letrozole versus methotrexate for treatment of ectopic pregnancy: A randomized controlled trial

ObjectiveTo evaluate the efficacy of two different regimens of Letrozole, an aromatase inhibitor, in the management of ectopic pregnancy compared to methotrexate. Study DesignThis randomized controlled trial was conducted on 88 women diagnosed with ectopic pregnancy with a baseline level of serum beta-human chorionic gonadotropin under 3000 mIU/mL between June 30, 2023, and December 30, 2023, at the Department of Obstetrics and Gynecology of the Vali-e-Asr Hospital affiliated with Tehran University of Medical Sciences. Participants were allocated into either methotrexate (n = 43), 5-day course Letrozole (n = 24), or 10-day course Letrozole (n = 21) treatments. The methotrexate group received a single dose of 50 mg/m2 dosage intramuscular methotrexate. The 5-day Letrozole group received a 2.5 mg Letrozole tablet three times daily for 5 days, whereas the 10-day Letrozole group received a 2.5 mg Letrozole tablet twice daily for 10 days. The primary outcome was the treatment response, defined as the achievement of a negative serum beta-human chorionic level without the need for additional methotrexate treatment or surgery. The secondary outcomes were the need for additional methotrexate dose or laparoscopic surgery intervention. The trial protocol was prospectively registered in ClinicalTrials.gov with code NCT05918718. ResultsThe treatment response rates in methotrexate, 5-day Letrozole, and 10-day Letrozole groups were 76.7 %, 75.0 %, and 90.5 %, respectively, with no significant differences between the groups (P-value = 0.358). A total of 10 (23.3 %) patients from the methotrexate group, 3 (12.5 %) from the 5-day Letrozole group, and 2 (9.5 %) from the 10-day Letrozole group required an additional methotrexate dose, with no significant differences between the groups (P-value = 0.307). Furthermore, only 3 (12.5 %) patients, all from the 5-day Letrozole group, were suspected of tubal rupture and underwent surgery (P-value = 0.016). ConclusionOur findings suggest Letrozole as a safe alternative to methotrexate in treating stable ectopic pregnancies, with a favorable treatment response rate. However, there is still a need for future larger studies to determine the applicability of Letrozole in the EP management. Also, the non-significant higher effectiveness of the 10-day Letrozole regimen than the 5-day Letrozole group underscores the need for future research to determine the optimal Letrozole regimen for the management of ectopic pregnancy.

Proportion of hydatidiform molar gestations among patients undergoing uterine evacuation for missed abortions, associated demographics and risk factors -Experience at a single center over 18 months

Objectives: Gestational trophoblastic diseases represent a significant obstetric morbidity among women of reproductive age, with a potential to impact women’s health substantially. Molar pregnancies present as clinical aberrations in embryogenesis and placentation during the first trimester of pregnancy. Cases with missed abortions and spontaneous incomplete abortions requiring uterine evacuation, could be an opportunity to look for molar pregnancies through histopathology which otherwise could be missed. We aim to study the proportion of hydatidiform molar gestations among patients undergoing uterine evacuation in cases of missed abortion and to evaluate the demographic and risk factors associated with hydatidiform molar gestations. Material and Methods: A prospective observational, descriptive study was conducted at the Department of Obstetrics and Gynecology of a tertiary care teaching hospital over a period of 18 months. Data was collected using a pre-tested study questionnaire which included the objectives, besides the inclusion and exclusion criteria. The abortus and uterine evacuated tissue was sent for histopathologic examination by a single histopathologist. Analysis of various epidemiological characteristics and risk factors was done using the Statistical Package for the Social Sciences software version 21. Results: Out of 67 patients presenting with missed abortions or incomplete abortions during the study period, five had hydatidiform molar gestations; an incidence of 7.5%. Upon histological examination 3 (4.5%) patients had a complete mole, 2 (3%) had a partial mole while 62 (92.5%) had non-molar histopathology. Eleven (16.4%) of the study participants had a history of previous spontaneous pregnancy loss/recurrent pregnancy losses. Three among five cases detected to have molar gestations had a history of prior spontaneous abortions (60%), and the difference observed was statistically significant (P = 0.019; Odds Ratio [95% Confidence interval] 10.25 [1.459–70.257]). Hyperthyroidism and high levels of serum beta-human chorionic gonadotrophin (β-HCG) were associated with molar gestations and this was statistically significant. Conclusion: The risk of developing molar gestation is higher in patients who had previous first-trimester losses. Importantly, this should be a differential diagnosis in instances with elevated β-HCG and high thyroid hormone levels. Histopathological examination of products of conception should be considered as an essential assessment in all presentations of spontaneous abortions requiring uterine evacuation.

A Study to Determine the Reason for Lower Pregnancy Rates in Younger Women with Diminished Oocyte Reserve-less Chance of Implanting vs. Fetal Demise

Most studies find lower live-delivered pregnancy rates (LDPRs) following in vitro fertilization-embryo transfer (IVF-ET) in women with diminished oocyte reserve (DOR) vs. normal oocyte reserve (NOR) even in a younger population. How much of a discrepancy may depend on the degree of oocyte depletion in the DOR group and the follicular stimulation protocol. Some fertility specialists favor an FSH receptor up-regulation technique as the protocol to attain the maximum LDPRs in women with DOR. The objective of this study was to compare chemical, clinical, and LDPRs following IVF-ET to determine if the main time of embryo loss is very early, as evidenced by the largest discrepancy occurring in attaining even a chemical pregnancy, and/ or a large discrepancy between a chemical pregnancy and attaining a clinical pregnancy (ultrasound evidence of a gestational sac) or later losses as evidenced by showing a greater loss rate from clinical evidence of pregnancy to live delivery in those with DOR compared to NOR. Overall, the DOR group, with a mean serum anti-Mullerian hormone (AMH) level of 0.42 ng/mL, had 50% as much chance to have an LDPR/transfer as women with NOR (AMH of 4.66) despite the same number of day 3 embryos transferred. The main reduction in LDPRs occurred from embryo transfer failing to attain a positive clinical pregnancy in the DOR group. The least discrepancy was from attaining a clinical pregnancy to live delivery. Thus, for NOR from positive pregnancy test 59% of this younger age group will have a live delivery vs. 50% for DOR. Thus, the reduction in LDPRS/transfer in young women with DOR vs. NOR seems mostly very early so the DOR group does not even attain a positive serum beta human chorionic gonadotropin level. This suggests that this inferiority in attaining a live delivery may be related to aneuploidy involving large chromosomes or a marked decrease in the mitochondrial DNA of the embryo.

FDG PET/CT Findings of Primary Pulmonary Choriocarcinoma in a Postmenopausal Woman.

Choriocarcinomas usually occur in the genital tracts of reproductive-age women after a gestational event. Primary pulmonary choriocarcinoma is very rare. We describe FDG PET/CT findings of primary pulmonary choriocarcinoma with multiple intrapulmonary metastases in a postmenopausal woman with elevated serum beta human chorionic gonadotropin level. On FDG PET/CT, the large primary lung tumor showed intense FDG uptake (SUV max , 46), and the small intrapulmonary metastases showed variable FDG uptake (SUV max , 27). Primary pulmonary choriocarcinoma should be included in the differential diagnosis of FDG-avid pulmonary lesions with elevated serum beta human chorionic gonadotropin levels, including metastatic choriocarcinoma and lung cancer.

Association of Serum Proteins Electrophoretic Pattern and Serum Hormones in Women with Spontaneous Pregnancy Loss.

Pregnancy is the state of carrying a developing embryo or fetus within a female body. Once pregnancy is established, a range of endocrinological events appear in its maintenance, finally helping in the successful pregnancy. The complications which are usually observed in pregnancy are gestational diabetes, preeclampsia, preterm labor, and spontaneous pregnancy loss or miscarriage, while 10%-15% of clinically recognized pregnancies terminate into spontaneous miscarriage. Thus, many attempts have been made by different researchers for the diagnosis of high-risk pregnancy on altered protein pattern using placental villous tissue or follicular fluid, but these are difficult to obtain and results of different studies are not constant. This study was designed to identify the association (if any) among serum protein(s) electrophoretic pattern and different serum hormones in normal pregnant women (controls) and gestational age-matched women with spontaneous pregnancy loss (cases). This study was carried out for 1½ year from October 2018 to March 2020 and included 120 participants (60 normal pregnant women and 60 women with spontaneous pregnancy loss) between 20 and 45 years of age with no mean age difference. The electrophoresis of serum was carried out using slab gel electrophoretic unit and serum thyroid-stimulating hormone (TSH), total tri-iodothyronine (TT3), total thyroxine (TT4), prolactin, and beta human chorionic gonadotropin (β-hCG) levels were analyzed using TSOSH AIA analyzer at Adesh University, Bathinda. Significant variations in the expression of proteins with molecular weight around ~150 kDa, ~50 kDa, and ~25 kDa were observed in normal pregnant women and women with spontaneous pregnancy loss. However, the protein band of ~50 kDa was found to be highly expressed in the serum of 1st and 2nd trimester women experiencing spontaneous pregnancy loss. Therefore, selected protein band of ~50 kDa was further processed by ECI-mass spectrophotometry QUAD time of flight and 365 different proteins were found, out of these; 34 proteins were found to be unidentified protein products (Verified using NCBI data base). Further, TT3, total proteins, β-hCG, and prolactin level were found to be low, whereas, TSH was found to be high in women experiencing spontaneous pregnancy loss. However, difference in the level of β-hCG in the 1st trimester and TT4 among normal pregnant women and women with spontaneous pregnancy loss was observed to be statistically insignificant. This study indicated that the evaluation of serum protein variations along with hormonal profile may provide valuable information about high-risk pregnancy. Moreover, the differential expression of proteins in women with spontaneous pregnancy loss can be further explored to develop potential biomarker for the early identification of high-risk pregnancy and appropriate preventive measure.

Post molar choriocarcinoma with solitary renal metastasis in the absence of primary uterine tumor: a case report and review of the literature

BackgroundChoriocarcinoma is a rare and highly malignant form of gestational trophoblastic disease that may develop following pregnancy, abortion, or a hydatiform mole. Renal metastatic involvement by post molar choriocarcinoma is even rarer. In this case report, we describe a unique case of post molar choriocarcinoma with a solitary renal metastasis in the absence of a primary uterine tumor and metastases in other sites, which presented with urological symptoms and spontaneous renal hemorrhage.Case presentationA 41-year-old Persian woman with history of complete hydatiform mole presented with severe flank pain, nausea, vomiting, gross hematuria, and vaginal bleeding. Laboratory tests demonstrated a serum beta human chorionic gonadotropin hormone level of 60,000 mIU/mL. Imaging studies showed a lesion at the lower pole of the left kidney with active bleeding surrounded by hematoma, as well as an empty uterine cavity. Additionally, bilateral pleural effusion was detected without any lesion within the lungs. Subsequently, the patient underwent laparotomy, partial nephrectomy, and left para-ovarian cystectomy. Endometrial curettage was also carried out. The histopathology report revealed choriocarcinoma renal metastasis with high expression of beta human chorionic gonadotropin, cytokeratin 7, and Ki 67. Moreover, there were no malignant cells in the endometrial curettage specimens, and a corpus luteum cyst was found within the para-ovarian cyst. Further investigations revealed that the pleural effusion was free of malignant cells, and there was no evidence of metastatic lesions in the brain. As a result, the patient was referred to the oncology department to receive chemotherapy, and the beta human chorionic gonadotropin levels dropped to 5 mIU/mL after receiving courses of a standard regimen of etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine/oncovin over 3 weeks. Finally, monthly measurements of beta human chorionic gonadotropin levels for 6 months indicated that levels have constantly remained within normal ranges, showing no evidence of recurrence or new metastasis.ConclusionsUrological symptoms such as hematuria or spontaneous renal hemorrhage might be the only presentation of post molar choriocarcinoma with renal involvement. Thus, it can be beneficial to measure serum beta human chorionic gonadotropin levels among females of childbearing age who present with unexplained urological symptoms, especially if there is a history of prior hydatiform mole.

Rare occurrence of ovarian choriocarcinoma: ultrasound evaluation.

Choriocarcinoma of the ovary is a rare, highly malignant tumor showing malignant trophoblastic cells and produces human chorionic gonadotropins. It can be classified as gestational and non-gestational choriocarcinoma. Non-gestational choriocarcinoma is extremely rare. Treatment is Methotrexate-based chemotherapy for the gestational type. This case study is a rare case of ovarian choriocarcinoma managed by surgical resection, followed by methotrexate-based chemotherapy, and aimed to evaluate the ultrasound characteristics of ovarian choriocarcinoma and how to arrive at the diagnosis. In cases with an elevated serum beta-human chorionic gonadotropin (beta hCG), the finding of a highly vascularized adnexal mass on ultrasound evaluation should be underlined as a clue for suspecting choriocarcinoma, particularly if the female was young with no marriage history or history of sexual intercourse and also to be highly considered in married females with history of repeated abortions, molar pregnancy or uterine choriocarcinoma.

Ultrasonography Findings in Post-Methotrexate Treatment of Cesarean Scar Pregnancy

Background: Cesarean scar pregnancy (CSP) can cause life-threatening complications for pregnant women, so early diagnosis and treatment are crucial for the prevention of maternal mortality. Transvaginal color Doppler ultrasonography, along with serum beta-human chorionic gonadotropin (β-hCG) level follow-up, can be a noninvasive and proper method for the post-treatment follow-up of a CSP. The present study investigated the Doppler resistance index (RI) changes in CSPs after medical management with methotrexate (MTX), evaluated by sac diameter and serum β-hCG level measurement. Methods: Overall, 28 patients with CSP and a history of previous cesarean delivery, a gestational age of less than 9 completed weeks at ultrasonography, the decision to medical management by the gynecologist, and having a β-hCG level before treatment were enrolled and initially examined by ultrasound and Doppler studies. The RI of the closest myometrial artery to the CSP mass and its diameter underwent measurement. After 72 hours, 1 week, and 2 weeks of medical therapy with MTX, the mentioned variables were measured again and compared with the values of the pretreatment time point. Results: RI values were significantly higher at all the follow-up time points compared with the pre-treatment time points, while serum β-hCG levels were significantly lower. Moreover, sac diameter values increased 72 hours post-treatment and then represented a decline. Conclusion: Serial Doppler ultrasound examination can be a useful method to evaluate the success or failure of the medical management of CSPs, as the increase in RI values occurs rapidly after medical treatment and correlates well with serum β-hCG levels.
