Diagnostic utility of clinicodemographic, biochemical and metabolite variables to identify viable pregnancies in a symptomatic cohort during early gestation. Sci Rep 2024; 14:11172. [PMID: 38750192 PMCID: PMC11096363 DOI: 10.1038/s41598-024-61690-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 05/08/2024] [Indexed: 05/18/2024] Open
Abstract
A significant number of pregnancies are lost in the first trimester and 1-2% are ectopic pregnancies (EPs). Early pregnancy loss in general can cause significant morbidity with bleeding or infection, while EPs are the leading cause of maternal mortality in the first trimester. Symptoms of pregnancy loss and EP are very similar (including pain and bleeding); however, these symptoms are also common in live normally sited pregnancies (LNSP). To date, no biomarkers have been identified to differentiate LNSP from pregnancies that will not progress beyond early gestation (non-viable or EPs), defined together as combined adverse outcomes (CAO). In this study, we present a novel machine learning pipeline to create prediction models that identify a composite biomarker to differentiate LNSP from CAO in symptomatic women. This prospective cohort study included 370 participants. A single blood sample was prospectively collected from participants on first emergency presentation prior to final clinical diagnosis of pregnancy outcome: LNSP, miscarriage, pregnancy of unknown location (PUL) or tubal EP (tEP). Miscarriage, PUL and tEP were grouped together into a CAO group. Human chorionic gonadotrophin β (β-hCG) and progesterone concentrations were measured in plasma. Serum samples were subjected to untargeted metabolomic profiling. The cohort was randomly split into train and validation data sets, with the train data set subjected to variable selection. Nine metabolite signals were identified as key discriminators of LNSP versus CAO. Random forest models were constructed using stable metabolite signals alone, or in combination with plasma hormone concentrations and demographic data. When comparing LNSP with CAO, a model with stable metabolite signals only demonstrated a modest predictive accuracy (0.68), which was comparable to a model of β-hCG and progesterone (0.71). The best model for LNSP prediction comprised stable metabolite signals and hormone concentrations (accuracy = 0.79). In conclusion, serum metabolite levels and biochemical markers from a single blood sample possess modest predictive utility in differentiating LNSP from CAO pregnancies upon first presentation, which is improved by variable selection and combination using machine learning. A diagnostic test to confirm LNSP and thus exclude pregnancies affecting maternal morbidity and potentially life-threatening outcomes would be invaluable in emergency situations.

Muacevic A, Adler JR. The Utility of Monitoring Beta-Human Chorionic Gonadotropin Levels in an Ectopic Pregnancy. Cureus 2023; 15:e34063.

Abstract
Ectopic pregnancy, a rare complication involving embryo nidation outside the uterus, significantly impacts women's lives worldwide. About 95% of ectopic pregnancies occur in the Fallopian tubes. If not diagnosed early, the patient may suffer from tubal rupture, resulting in hemorrhage and lethal consequences. Transvaginal ultrasound (TVUS) is typically used to diagnose an ectopic pregnancy. However, over the last decade, monitoring beta-human chorionic gonadotropin (β-hCG) levels in ectopic pregnancy have evolved to detect ectopic pregnancy. But there are inconsistencies in its utility in monitoring or diagnosing ectopic pregnancy in clinical practice. This systematic review highlights the potential of monitoring β-hCG levels to accurately diagnose ectopic pregnancy. Furthermore, it showcases if β-hCG levels can determine effective treatment options to successfully resolve an ectopic pregnancy. We performed a literature search between January 2022 through December 2022 following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. The clinical evidence demonstrated that monitoring β-hCG levels, combined with TVUS, accurately diagnosed an ectopic pregnancy. Moreover, pre-treatment β-hCG levels higher than 5000 international units per liter (IU/L), statistically significant, indicated surgical management for a successful resolution of an ectopic pregnancy. Whereas lower β-hCG levels showed successful management through expectant and methotrexate treatment. Interestingly, patients who failed non-surgical treatment developed increased β-hCG levels and required surgical intervention. However, there was conflicting evidence on whether β-hCG levels could indicate tubal rupture. Nevertheless, as highlighted in this review, monitoring β-hCG levels could be crucial in the early diagnosis of ectopic pregnancy. Besides, it might significantly aid in monitoring and deciding on effective treatment options for patients with ectopic pregnancy, which could be vital to saving their lives and preserving fertility.

Abstract
Objective Ectopic pregnancy (EP) is well known for its critical maternal outcome. Early detection could make the difference between life and death in pregnancy. Our aim was to make a prompt diagnosis before the rupture occur. Thus, the predictive analytical models using both conventional statistics and machine learning (ML) methods were studied. Materials and methods A retrospective cohort study was conducted on 407 pregnancies with unknown location (PULs): 306 PULs for internal validation and 101 PULs for external validation, randomized with a nested cross-validation technique. Using a set of 22 study features based on clinical factors, serum marker and ultrasound findings from electronic medical records, analyzing with neural networks (NNs), decision tree (DT), support vector machines (SVMs), and a statistical logistic regression (LR). Diagnostic performances were compared with the area under the curve (ROC-AUC), including sensitivity and specificity for decisional use. Results Comparing model performance (internal validation) to predict EP, LR ranked first, with a mean ROC-AUC ± SD of 0.879 ± 0.010. In testing data (external validation), NNs ranked first, followed closely by LR, SVMs, and DT with average ROC-AUC ± SD of 0.898 ± 0.027, 0.896 ± 0.034, 0.882 ± 0.029, and 0.856 ± 0.033, respectively. For clinical aid, we report sensitivity of mean ± SD in LR: 90.20% ± 3.49%; SVM: 89.79% ± 3.66%; DT: 89.22% ± 4.53%; and NNs: 86.92% ± 3.24%, consecutively. However, specificity ± SD was ranked by NNs, followed by SVMs, LR, and DT, which were 82.02 ± 8.34%, 80.37 ± 5.15%, 79.65% ± 6.01%, and 78.97% ± 4.07%, respectively. Conclusion Both statistics and the ML model could achieve satisfactory predictions for EP. In model learning, the highest ranked model was LR, showing that EP prediction might possess linear or causal data pattern. However, in new testing data, NNs could overcome statistics. This highlights the potency of ML in solving complicated problems with various patterns, while overcoming generalization error of data.

Abstract
Introduction Ruptured ectopic pregnancy is one of the leading causes of maternal death. Point-of-care ultrasound (POCUS) has been shown to be highly sensitive for excluding ectopic pregnancy. Ectopic pregnancy after a hysterectomy is a rare but life-threatening occurrence. We present a case where POCUS helped to diagnose a post-hysterectomy ectopic pregnancy. Case report A 36-year-old female with a prior surgical history of hysterectomy without oophorectomy presented to the emergency department with lower abdominal pain. A POCUS revealed free fluid in the right upper quadrant with an unremarkable gallbladder. Subsequently, the pelvic POCUS noted free fluid as well as a heterogeneous structure in the right adnexa. The clinician ordered a serum beta human chorionic gonadotropin level, which was 173.2 international units per milliliter (lU/mL) (negative: < 5m IU/ml). Transvaginal ultrasound revealed a right adnexal echogenic structure with surrounding vascularity and moderate, complex free fluid suggestive of hemorrhage. Given the concern for possible ectopic pregnancy, obstetrics took the patient to the operating room where a right tubal ectopic pregnancy was confirmed. Conclusion A ruptured ectopic pregnancy is a life-threatening condition that requires rapid diagnosis. Ectopic pregnancy post hysterectomy is an uncommon occurrence infrequently considered in the differential diagnosis of lower abdominal pain, leading to considerable delays in diagnosis. Although uncommon, emergency clinicians must consider this diagnosis in female patients with lower abdominal pain.

Abstract
ABSTRACT Ectopic pregnancy (EP) is a known cause of maternal mortality and may be misdiagnosed in up to 50% of pregnant female individuals (Ann Emerg Med. 1996;28(1):10-17). Magnetic resonance imaging, with its superior soft tissue resolution, is a valuable alternative diagnostic modality to diagnose EP when transvaginal ultrasound results are inconclusive. Although an extrauterine gestational sac is the most specific finding, there are other key MRI findings that can aid in diagnosing EP. As availability of MRI access in the emergency department setting increases across the nation, its utility in women with a positive pregnancy test has also increased. Specific MRI findings that are diagnostic of EP include absence of intrauterine pregnancy, adnexal mass separate from the ovary, and hemoperitoneum. In addition, intrauterine ectopic locations, especially intramural, cornual, and cervical pregnancies, can be diagnosed with increased accuracy with the help of MRI. Magnetic resonance imaging is also useful in excluding potential mimics of EP, including adnexal cysts, ovarian neoplasms, and fibroids. In summary, providing an accurate diagnosis and determining the precise location of an EP, which is supported by the use of MRI, is imperative for guiding a patient's treatment to prevent a potentially fatal outcome.

Abstract
BACKGROUND Point-of-care ultrasound (POCUS) is useful in the evaluation of early pregnancy by confirming intrauterine pregnancy and recognizing hemorrhage from ectopic pregnancy. We sought to determine whether transabdominal POCUS by itself or in conjunction with consultative radiology ultrasound (RADUS), reduces Emergency Department (ED) treatment time for patients with ectopic pregnancy requiring operative care, when compared to RADUS alone. A secondary objective was to determine whether the incorporation of POCUS reduces time to operative care for patients with ruptured ectopic pregnancy specifically, when compared to RADUS alone. METHODS We performed a retrospective review of patients admitted for operative management of ectopic pregnancy. We excluded patients with known ectopic pregnancy and/or imaging prior to arriving to the treatment area, found not to have an ectopic pregnancy, or did not undergo operative care. Descriptive statistics, classical and nonparametric statistical analysis, and linear regression were performed. RESULTS There were 220 patients admitted with ectopic pregnancy, 111 met exclusion criteria, yielding 109 for analysis. Of 109, 36 received POCUS (23/36 also had RADUS), while 73 received RADUS only. Among the POCUS group 31/36 (86%) were classified as ruptured versus 47/73 (64%) in the RADUS group. The average ED treatment time in the POCUS group for all admitted ectopic pregnancies was 157.9 min (standard deviation [SD] 101.3) versus 206.3 min (SD 76.6) in the RADUS group (p = 0.0141). The median time to operating room (OR) for ruptured ectopic pregnancies was 203.0 min (interquartile range [IQR] 159.0) in the POCUS group versus 293.0 min (IQR 139.0) in the RADUS group (p = 0.0002). Regression analysis of the primary outcome was limited by multiple interactions and sample size. When controlling for race, positive shock index and ED visit time, POCUS was found to be associated with a significantly shorter time to OR among ruptured ectopic pregnancies compared to RADUS (p = 0.0052). CONCLUSION Compared to RADUS alone, incorporation of POCUS was associated with significantly faster ED treatment time for all ectopic pregnancies and significantly faster time to OR for ruptured ectopic pregnancies, even when combined with RADUS. When controlling for clinical differences, time to OR was still faster for patients who underwent POCUS. The integration of POCUS should be considered to expedite care for patients with ectopic pregnancy requiring operative care.

Abstract
Objective: Ectopic pregnancy (EP) is a serious condition. Delayed diagnosis could lead to life-threatening outcomes. The study aimed to develop a diagnostic predictive model for EP to approach suspected cases with prompt intervention before the rupture occurred. Methods: A retrospective cross-sectional study enrolled 347 pregnant women presenting first-trimester complications (abdominal pain or vaginal bleeding) with diagnosis suspected of pregnancy of unknown location, who were eligible and underwent chart review. The data including clinical risk factors, signs and symptoms, serum human chorionic gonadotropin (hCG), and ultrasound findings were analyzed. The statistical predictive score was developed by performing logistic regression analysis. The testing data of 30 patients were performed to test the validation of predictive scoring. Results: From a total of 22 factors, logistic regression method–derived scoring model was based on five potent factors (history of pelvic inflammatory disease, current use of emergency pills, cervical motion tenderness, serum hCG ≥1,000 mIU/ml, and ultrasound finding of adnexal mass) using a cutoff score ≥3. This predictive index score was able to determine ectopic pregnancy with an accuracy of 77.8% [95% confidence interval (CI) = 73.1–82.1], specificity of 91.0% (95% CI = 62.1–72.0), sensitivity of 67.0% (95% CI = 88.0–94.0), and area under the curve of 0.906 (95% CI = 0.875–0.937). In the validation group, no patient with negative result of this score had an EP. Conclusion: Statistical predictive score was derived with high accuracy and applicable performance for EP diagnosis. This score could be used to support clinical decision making in routine practice for management of EP.

Abstract
Objective To study factors associated with the success of single dose methotrexate (MTX) treatment in women with ectopic pregnancy. Methods This is a retrospective study of women (n=110) with ectopic pregnancy and treated with single dose of MTX. The clinical presentations, transvaginal sonography (TVS) findings, pretreatment beta-human chorionic gonadotropin (β-HCG), and progesterone values were compared between the treatment success (Group S) and treatment failure (Group F) groups. Results The overall success rate of treatment with single dose of MTX was 75.45%. The majority of patients in both groups presented with pain and bleeding (~55%), and bleeding only was the presenting symptom in about 20% of patients. Only 3 patients (3.61%) in Group S required a repeat dose of MTX. In contrast, 51.8% of the Group F patients required a repeat dose. The mean pretreatment β-HCG level was 2.3 times higher in Group F than in Group S (1734±1684 vs 4036±2940 IU/L). The data showed a β-HCG level of 3924IU/L as a suitable cut-off value with 76.19% sensitivity and 62.5% specificity to predict MTX treatment success. History of ectopic pregnancy had no relation with success/treatment failure or a repeat dose. None of the TVS findings were related to the outcome of the treatment, whereas pretreatment HCG level was a significant predictor. Conclusion The single dose MTX treatment was successful in 75.45% (83/110) of cases, with 3.61% (3/83) requiring a repeat dose of the drug. Pretreatment β-HCG level is a significant predictor of the treatment outcome.

Abstract
Ectopic pregnancy occurs when a fertilized ovum attaches outside the uterus. As a complication in approximately 1‑2% of all pregnancies, ectopic pregnancies may cause catastrophic hemorrhage as a result of invading maternal blood vessels. Therefore, early diagnosis and timely treatment are crucial for women with ectopic pregnancy. In this study, we aimed to identify and determine the efficacy of serum biomarkers for the prompt diagnosis of ectopic pregnancy. For this purpose, the serum concentrations of progesterone, β human chorionic gonadotropin (β‑hCG) and cancer antigen‑125 (CA125) were detected by solid‑phase, competitive binding chemiluminescent enzyme immunoassays. Flow cytometry was used to analyze the percentage of CD3+ T cells in women with ectopic pregnancy. Pathological analysis of tubal and villus tissues was performed by hematoxylin and eosin (H&E) staining. After receiving an injection of methotrexate (MTX), patients were examined by transvaginal ultrasound to detect the size of the echogenic mass. The results revealed that the serum levels of progesterone, β‑HCG and CA125 were significantly decreased in women with ectopic pregnancy, whereas the percentage of CD3+ T cells was increased in women with ectopic pregnancy. Histopathological examination revealed blood clots with small tissue fragments of a tubal‑type epithelium and incomplete pile structures. Five days after the MTX injection, an echogenic mass was found with a size of 1.7x1.2x1.6 cm that contained a gestational sac‑like structure and a yolk sac. On the whole, the findings of this study indicate the at the joint detection of progesterone, β‑HCG, CA125 serum levels and the CD3+ T cell percentage could be applied as a reliable indicator for the early diagnosis of ectopic pregnancy. MTX administration was determined to be an efficacious approach for the treatment of ectopic pregnancy.

Abstract
Pregnancy can be complicated with different surgical emergencies which may potentially endanger the mother as well as foetus. In the modern era of advanced diagnostics and treatments, neither of them in response to a surgical emergency in a pregnant woman should be delayed. Appropriate early intervention is essential to decrease the morbidity and mortality. Following article encompasses common surgical emergencies that can arise in a pregnant woman and tries to suggest the approach that may be taken to reduce the burden of morbidity and mortality.

Morgan BB, Kao A, Trent SA, Hurst N, Oliveira L, Austin AL, Kendall JL. Effect of Emergency Physician-Performed Point-of-Care Ultrasound and Radiology Department-Performed Ultrasound Examinations on the Emergency Department Length of Stay Among Pregnant Women at Less Than 20 Weeks' Gestation. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2018; 37:2497-2505. [PMID: 29574878 DOI: 10.1002/jum.14607] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2017] [Revised: 01/09/2018] [Accepted: 01/28/2018] [Indexed: 06/08/2023]
Abstract
OBJECTIVES We sought to confirm retrospective studies that measured an approximately 20% reduction in emergency department (ED) length of stay (LOS) in early-gestation pregnant women who receive emergency physician-performed point-of-care ultrasound (US) examinations rather than radiology department-performed US examinations for evaluation of intrauterine pregnancy (IUP). METHODS A randomized controlled clinical trial was performed at an urban academic safety net hospital and 2 Naval medical centers in the United States. The allocation was concealed before enrollment. Clinically stable adult pregnant women at less than 20 weeks' gestation who presented to the ED with abdominal pain or vaginal bleeding were randomized to receive a point-of-care or radiology US to assess for IUP. The primary outcome measure was the ED LOS. RESULTS A total of 224 patients (point-of-care US, n = 118; radiology US, n = 106) were included for the analysis. The ED LOS was 20 minutes shorter in the point-of-care US arm (95% confidence interval [CI], -54 to 7 minutes). Adjusting for variability due to the location, the ED LOS was calculated to be 31 minutes shorter (95% CI, -64 to 1 minute) than for patients in the radiology US arm. Excluding patients in the point-of-care US arm who crossed over to radiology US after an inconclusive point-of-care US examination, the ED LOS was 75 minutes shorter than in the radiology US arm (95% CI, -97 to -53 minutes). CONCLUSIONS Early-gestation pregnant ED patients requiring pelvic US were discharged earlier when point-of-care US was used rather than radiology US; however, this trial did not achieve our target of 30 minutes. Nevertheless, our data support the routine use of ED point-of-care US for IUP, saving the most time if a conclusive IUP is identified.

Abstract
BACKGROUND There is no international consensus on how to manage women with a pregnancy of unknown location (PUL). OBJECTIVES To present a systematic quantitative review summarising the evidence related to management protocols for PUL. SEARCH STRATEGY MEDLINE, COCHRANE and DARE databases were searched from 1 January 1984 to 31 January 2017. The primary outcome was accurate risk prediction of women initially diagnosed with a PUL having an ectopic pregnancy (high risk) as opposed to either a failed PUL or intrauterine pregnancy (low risk). SELECTION CRITERIA All studies written in the English language, which were not case reports or series that assessed women classified as having a PUL at initial ultrasound. DATA COLLECTION AND ANALYSIS Forty-three studies were included. QUADAS-2 criteria were used to assess the risk of bias. We used a novel, linear mixed-effects model and constructed summary receiver operating characteristic curves for the thresholds of interest. MAIN RESULTS There was a high risk of differential verification bias in most studies. Meta-analyses of accuracy were performed on (i) single human chorionic gonadotrophin (hCG) cut-off levels, (ii) hCG ratio (hCG at 48 hours/initial hCG), (iii) single progesterone cut-off levels and (iv) the 'M4 model' (a logistic regression model based on the initial hCG and hCG ratio). For predicting an ectopic pregnancy, the areas under the curves (95% CI) for these four management protocols were as follows: (i) 0.42 (0.00-0.99), (ii) 0.69 (0.57-0.78), (iii) 0.69 (0.54-0.81) and (iv) 0.87 (0.83-0.91), respectively. CONCLUSIONS The M4 model was the best available method for predicting a final outcome of ectopic pregnancy. Developing and validating risk prediction models may optimise the management of PUL. TWEETABLE ABSTRACT Pregnancy of unknown location meta-analysis: M4 model has best test performance to predict ectopic pregnancy.

Abstract
Aim: The goal of this study was to identify potential risk factors for ectopic pregnancy in women followed in German gynecological practices. Methods: The present study included pregnant women diagnosed with ectopic pregnancy and pregnant women without ectopic pregnancy followed in 262 gynecological practices between January 2012 and December 2016. The effects of demographic and clinical variables on the risk of developing ectopic pregnancy were estimated using a multivariate logistic regression model. Results: This study included 3,003 women with ectopic pregnancy and 97,194 women without ectopic pregnancy. The mean age was 31.4 years (SD=5.9 years) in ectopic pregnancy patients and 31.1 years (SD=5.6 years) in non-ectopic pregnancy patients. Women aged 36–40 (OR=1.12) and 41–45 years (OR=1.46) were at a higher risk of ectopic pregnancy than women aged 31–35 years. Prior ectopic pregnancy was strongly associated with a risk of recurring ectopic pregnancy (OR=8.17). Prior genital surgery (OR=2.67), endometriosis (OR=1.51), and eight other gynecological diseases were also positively associated with ectopic pregnancy (ORs ranging from 1.19 to 2.06). Finally, there was a 1.80-fold increase in women previously diagnosed with psychiatric disorders. Conclusions: Prior ectopic pregnancy and prior genital surgery were strongly associated with ectopic pregnancy in women followed in German gynecological practices. Psychiatric diseases had an additional impact on the risk of ectopic pregnancy.

Abstract
BACKGROUND Ectopic pregnancy (EP) is an important cause of morbidity and mortality in females of reproductive age. Proper diagnosis and treatment are critical, as complications such as rupture, hemorrhagic shock, and even death can occur. OBJECTIVE EP is a condition emergency physicians are trained to detect, yet there are multiple myths concerning its evaluation and diagnosis. This article reviews several of these myths in order to improve emergency department (ED) evaluation and diagnosis. DISCUSSION EP is a difficult diagnosis and may be missed on initial ED visit. While the diagnosis is often delayed simply due to very early presentations, it can also be missed because patients may not have all the same risk factors or demonstrate the same symptoms. They may also not demonstrate the same serum B-human chorionic gonadotropin levels and trends or have the same ultrasound findings at equivalent gestational ages. Some patients with early EP may have positive ultrasound findings with serum β-hCG levels under a defined discriminatory zone (DZ). On the other hand, some patients with an early viable intrauterine pregnancy may have no visible findings on initial ultrasound, but have serum β-hCG (quantitative) levels well above the DZ. Although rare, EP has even been demonstrated in women with negative urine β-hCG tests or low serum β-hCG levels. CONCLUSIONS While EP may be a challenging diagnosis, understanding the myths surrounding EP may help emergency physicians consider it, even when patient risk factors, symptoms, or ED laboratory or imaging studies do not initially or easily define the diagnosis.

Abstract
The purpose of this article is to help the practitioner ensure early diagnosis and response to emergencies in the first trimester by reviewing anatomy of the developing embryo, highlighting the sonographic appearance of common first-trimester emergencies, and discussing key management pathways for treating emergent cases. First-trimester fetal development is a stepwise process that can be challenging to evaluate in the emergency department (ED) setting. This is due, in part, to the complex anatomy of early pregnancy, subtlety of the sonographic findings, and the fact that fewer than half of patients with ectopic pregnancy present with the classic clinical findings of a positive pregnancy test, vaginal bleeding, pelvic pain, and tender adnexa. Ultrasound (US) has been the primary approach to diagnostic imaging of first-trimester emergencies, with magnetic resonance imaging (MRI) and computed tomography (CT) playing a supportive role in a small minority of cases. Familiarity with the sonographic findings diagnostic of and suspicious for early pregnancy failure, ectopic pregnancy, retained products of conception, gestational trophoblastic disease, failed intrauterine devices, and complications associated with assisted reproductive technology (ART) is critical for any emergency radiologist. Evaluation of first-trimester emergencies is challenging, and knowledge of key imaging findings and familiarity with management pathways are needed to ensure early diagnosis and response.

Abstract
Historically, ectopic pregnancy was a life-threatening condition where diagnosis was possible only at post mortem or laparotomy and maternal mortality was up to 90%. The evolution in the management of ectopic pregnancy has meant that diagnosis can be made using non-invasive techniques with an aim to identify the ectopic gestation before tubal rupture. This enables health care professionals to offer management options that consider not only maternal mortality, but morbidity and fertility outcomes as well. In spite of this, diagnostic techniques and management options are not without limitations. Research is currently focused on new tests with a single diagnostic capability, diagnostic and treatment algorithms and safe methods of triaging patients. This article aims to review the current literature on the diagnosis and management of ectopic pregnancy and to formulate a pathway to help individualise care and achieve the best possible outcome.

Abstract
BACKGROUND Acute abdominal pain (AAP) accounts for 7-10% of all Emergency Department (ED) visits. Nevertheless, the epidemiology of AAP in the ED is scarcely known. The aim of this study was to investigate the epidemiology and the outcomes of AAP in an adult population admitted to an urban ED. METHODS We made a retrospective analysis of all records of ED visits for AAP during the year 2014. All the patients with repeated ED admissions for AAP within 5 and 30 days were scrutinized. Five thousand three hundred and forty cases of AAP were analyzed. RESULTS The mean age was 49 years. The most frequent causes were nonspecific abdominal pain (NSAP) (31.46%), and renal colic (31.18%). Biliary colic/cholecystitis, and diverticulitis were more prevalent in patients aged >65 years (13.17% vs. 5.95%, and 7.28% vs. 2.47%, respectively). Appendicitis (i.e., 4.54% vs. 1.47%) and renal colic (34.48% vs. 20.84%) were more frequent in patients aged <65 years. NSAP was the most common cause in both age classes. Renal colic was the most frequent cause of ED admission in men, whereas NSAP was more prevalent in women. Urinary tract infection was higher in women. Overall, 885 patients (16.57%) were hospitalized. Four hundred and eighty-five patients had repeated ED visits throughout the study period. Among these, 302 patients (6.46%) were readmitted within 30 days, whereas 187 patients (3.82%) were readmitted within 5 days. Renal colic was the first cause for ED readmission, followed by NSAP. In 13 cases readmitted to the ED within 5 days, and in 16 cases readmitted between 5-30 days the diagnosis was changed. CONCLUSIONS Our study showed that AAP represented 5.76% of total ED visits. Two conditions (i.e., NSAP and renal colic) represented >60% of all causes. A large use of active clinical observations during ED stay (52% of our patients) lead to a negligible percentage of changing diagnosis at the second visit.

Abstract
Background. One of the treatment modalities for ectopic pregnancy is methotrexate. The purpose of this study is to identify the failure rate of methotrexate in treating patients with ectopic pregnancy as well as the risk factors leading to treatment failure. Methods. A retrospective chart review of 225 patients who received methotrexate as a primary management option for ectopic pregnancy. Failure of single dose of methotrexate was defined as drop of BHCG level less than or equal to 14% in the seventh day after administration of methotrexate. Results. 225 patients had methotrexate. Most of the patients (151 (67%)) received methotrexate based on the following formula: f 50 mg X body surface area. Single dose of methotrexate was successful in 72% (162/225) of the patients. 28% (63/225) were labeled as failure of single dose of methotrexate because of suboptimal drop in BhCG. 63% (40/63) of failure received a second dose of methotrexate, and 37% (23/63) underwent surgical treatment. Among patient who received initial dose of methotrexate, 71% had moderate or severe pain, and 58% had ectopic mass size of more than 4 cm on ultrasound. Conclusion. Liberal use of medical treatment of ectopic pregnancy results in 71% success rate.

Abstract
BACKGROUND Pregnant female patients with vaginal bleeding in the first trimester are seen commonly in the Emergency Department (ED) at the University Hospital of the West Indies (UHWI), Kingston, Jamaica. The protocol for the management of these patients requires that they have a sonographic evaluation performed for the purpose of localizing the pregnancy where possible, to assist with determining the risk for an ectopic pregnancy. The ultrasound examinations are performed in the radiology department. OBJECTIVE This retrospective study was conducted to evaluate how long patients wait for a pelvic ultrasound. We also sought to establish how many patients had ultrasound findings that would have allowed safe discharge home. METHODS The records of 150 patients seen in the six-month period from January 1 to July 30, 2008 were examined. Data were extracted pertaining to age, time to see an emergency room doctor, time taken for ultrasound examination to be obtained from the radiology department and the ultrasound findings. RESULT Fifty-four per cent presented to the Emergency Department with a complaint of vaginal bleeding and abdominal pain, 29% with bleeding only, 16% with abdominal pain only and one with syncope. One hundred and sixteen of the patients enrolled had an ultrasound performed at UHWI. The average waiting time for an ultrasound was 3.8 ± 2.5 hours. The majority (66/116) of the patients had an intrauterine pregnancy (IUP) demonstrated on ultrasound. Twenty-nine had no IUP, free fluid or adnexal mass. These 95 patients would likely have been discharged home. Ten patients had an adnexal mass with or without free fluid, and ten had free fluid only on ultrasound. One patient was found to have a definite ectopic pregnancy. These 21 patients would have been referred for evaluation by the obstetrician on call for further management. CONCLUSION The majority of patients had sonographic findings that would have allowed safe and timely discharge from the Emergency Department had ultrasound been available at the point of care.

Abstract
BACKGROUND: This study aimed to determine the necessity of pregnancy test in women of reproductive age admitted to emergency department (ED) in routine practice. METHODS: We retrospectively reviewed the records of patients who presented to the ED between January 1, 2006 and December 31, 2010 and received a pregnancy test. RESULTS: The median age of 1 586 patients enrolled into the study was 27 years. Of these patients, 19.55% had a positive result of pregnancy test. The most common complaint at admission was abdominal pain in 60.15% of the patients, and pregnancy test was prescribed. 15.83% of the patients with abdominal pain had a positive result of pregnancy test. Of the patients, 30.64% had nausea-vomiting at admission, and 11.52% had a positive result of pregnancy test. When other complaints were considered, the most commonly observed complaints were non-specific symptoms such as dizziness, malaise and respiratory problems. Of the patients, 70.93% were not remembering the date of last menstruation, and 9.51% showed a positive result of pregnancy test. Urinary tract infection (UTI) was commonly diagnosed with an incidence of 17.65%, which was followed by non-specific abdominal pain (NSAP) (16.77%) and gastrointestinal disorders such as gastritis and peptic ulcer (6.87%). Of the patients, 88.40% were discharged from ED, and 11.60% were hospitalized. CONCLUSION: Pregnancy test should be given to women of reproductive age as a routine practice in ED in developing countries like Turkey.

Abstract
OBJECTIVE To evaluate factors associated with accuracy of initial ultrasonography in patients with symptomatic first-trimester pregnancy. METHODS Ultrasound diagnosis in the emergency department was compared with an ultimate clinical diagnosis in women in need of a gynecologic consult. The sensitivity, specificity, positive predictive values, and accuracy of the initial ultrasound impression were calculated and stratified by criteria of diagnosis, serum human chorionic gonadotropin (hCG) levels, pain, and bleeding. RESULTS Eighteen hundred eighty women were evaluated. Overall accuracy of initial ultrasound diagnosis was 78%. A probable ultrasound diagnosis of ectopic pregnancy (adnexal mass without the presence of a yolk sac or embryo) resulted in a higher sensitivity (42.1% compared with 13.2%: P<.001) but a lower positive predictive value (82.7% compared with 98%: P<.01) compared with a definite diagnosis. A probable ultrasound diagnosis of intrauterine pregnancy (double decidual sign without yolk sac or embryo) resulted in a higher sensitivity (36.0% compared with 4.0%; P<.001) and lower positive predictive value (58.8% compared with 87.0%; P>.001) compared with a definite diagnosis. The sensitivity (34.3% compared with 75.9%; P<.01) and positive predictive value (80.4% compared with 91.5%; P=.02) were lower for diagnosis of ectopic pregnancy when serum hCG level was less than 2,000 milli-international units/mL. Ultrasonography was less accurate when bleeding was the chief complaint (72.7% compared with 84.8% P<.006) but not substantially altered by pain as a chief complaint (78.0 compared with 77.8% P>.99). CONCLUSION A substantial number of misdiagnoses can occur when initial ultrasound diagnosis of intrauterine pregnancy or ectopic pregnancy is made without evidence of a yolk sac or embryo, when hCG values are low, or when a patient has significant bleeding.

Abstract
PURPOSE Ectopic pregnancy (EP) presents a major health problem for women of child-bearing age. EP refers to the pregnancy occurring outside the uterine cavity that constitutes 1.2-1.4 % of all reported pregnancies. All identified risk factors are maternal: pelvic inflammatory disease, Chlamydia trachomatis infection, smoking, tubal surgery, induced conception cycle, and endometriosis. These developments have provided the atmosphere for trials using methotrexate as a non-surgical treatment for EP. The diagnosis measure of EP is serum human chorionic gonadotropin, urinary hCGRP/i-hCG, progesterone measurement, transvaginal ultrasound scan, computed tomography, vascular endothelial growth factor, CK, disintegrin and metalloprotease-12 and hysterosalpingography. The treatment option of EP involves surgical treatment by laparotomy or laparoscopy, medical treatment is usually systemic or through local route, or by expectant treatment. RESULTS It was concluded that review data reflect a decrease in surgical treatment and not an actual decline in EP occurrence so that further new avenues are needed to explore early detection of the EP.

Prediction of location of gestational sac for pregnancy of unknown location at first sight during exploratory surgery using the ratio of hCG in haemoperitoneum and venous serum. Eur J Obstet Gynecol Reprod Biol 2013; 169:99-102. [PMID: 23490539 DOI: 10.1016/j.ejogrb.2013.02.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2012] [Revised: 10/17/2012] [Accepted: 02/03/2013] [Indexed: 10/27/2022]
Abstract
OBJECTIVE To evaluate a practical method to predict the location of gestational sacs for pregnancy of unknown location (PUL) during exploratory surgery. STUDY DESIGN Sixty-nine cases of PUL with a positive pregnancy test and haemoperitoneum but unknown location of the gestational sac at first sight on exploratory surgery were analysed at the Department of Obstetrics and Gynaecology, Shanghai Jiaotong University. The level of hCG in the haemoperitoneum and venous serum were measured, and the ratio of hCG in haemoperitoneum and venous serum (Rp/v-hCG) was calculated. Rp/v-hCG<1.0 was taken to suggest an intrauterine gestational sac, and Rp/v-hCG>1.0 was taken to suggest an abdominal gestational sac. The sensitivity and specificity of Rp/v-hCG for predicting the location of the gestational sac were evaluated prospectively. RESULTS Among 69 cases of PUL, 17 cases (17/69) were ultimately diagnosed as abdominal gestational sacs before 9 weeks of gestation, and 52 cases (52/69) were ultimately diagnosed as intrauterine gestational sacs. The diagnostic sensitivity and specificity of Rp/v-hCG at the time of exploratory surgery for predicting the location of the gestational sac were 94.1% and 100%, respectively (kappa=0.96; P=0.039). The rate of missed diagnosis was 5.9%. The location of the gestational sac was determined during the initial exploratory procedure for 15 cases (15/17) with an abdominal gestational sac (1 case of splenic pregnancy was diagnosed during secondary surgery) and 37 cases (37/52) with an intrauterine gestational sac. With the exception of gestational sacs located in the pouch of Douglas (52.9%, 9/17), the gestational sacs (47.1%, 8/17) located in the other places were difficult to find. CONCLUSIONS Rp/v-hCG should be considered when exploratory surgery reveals no visible gestational sacs at first sight. If Rp/v-hCG is >1.0, more careful pelvic or abdominal exploration is required, rather than dilation and curettage, to locate abdominal gestational sacs.

Abstract
Abdominal pregnancy is a rare condition that is potentially life-threatening for the mother. We present a case of simultaneous ectopic pregnancies (EPs) in the right fallopian tube and in the vesicouterine pouch. A 26-year-old woman had undergone prior ovulation induction with clomiphene citrate and human chorionic gonadotropin (hCG) at an outside hospital for unexplained infertility. The patient was referred to our hospital for a suspected ectopic pregnancy at 6 weeks gestation. Transvaginal ultrasonography detected a viable fetus at the anterior left side of the uterus; therefore, we suspected a left tubal pregnancy. However, laparoscopic surgery revealed that EPs were located in both the left vesicouterine pouch and in the right fallopian tube. Resection of the right salpinx and abdominal implant were performed. Histopathological examination confirmed the simultaneous presentation of a primary abdominal pregnancy and a right tubal pregnancy. After surgery, the patient's serum hCG level returned to normal. Concurrent EPs and abdominal pregnancy are very rare. However, it should be noted that reproductive technologies sometimes cause unusual clinical situations. A thorough abdominal inspection is needed.

Abstract
BACKGROUND Emergency physicians are increasingly performing transvaginal ultrasound (TVUS) to rule out ectopic pregnancy. However, little is known about appropriate educational pathways to train emergency medicine residents in TVUS. STUDY OBJECTIVES To evaluate the ability of Emergency Medicine (EM) residents who underwent a training program in TVUS to detect the presence or absence of an intrauterine pregnancy (IUP) in patients of < 13 weeks gestation with vaginal bleeding or abdominal pain, as compared to the final interpretation of each study as determined by the Emergency Department (ED) Director of Ultrasound. METHODS This was a prospective, observational study in a single residency program. Training included a lecture, competency examination, and 10 supervised TVUSs. The EM residents then performed TVUSs with the goal of determining the presence or absence of an IUP without input from an attending physician. Correlation with the ED Director of Ultrasound was assessed for the cohort, and stratified by year of training. RESULTS There were 22 residents who performed 75 TVUSs over 17 months. Correlation with the ED Director of Ultrasound was 93.3%. Differences in correlation with the ED Director of Ultrasound were noted when compared by year of training: post-graduate year (PGY)-3 (93.3%), PGY-2 (92.1%), and PGY-1 (100%); p < 0.001. CONCLUSION Residents were able to perform TVUSs to determine the presence or absence of an IUP in patients in whom the diagnosis of ectopic pregnancy was being considered with a high degree of correlation with the ED Director of Ultrasound after a brief training program. Correlation with the ED director of ultrasound was influenced by year of training.

Abstract
STUDY OBJECTIVE We seek to assess the performance of the β human chorionic gonadotropin (β-hCG) "discriminatory zone" when using bedside pelvic ultrasonography in the evaluation of symptomatic pregnant emergency department (ED) patients. METHODS This was a cross-sectional study of bedside pelvic ultrasonography performed on consecutive pregnant patients in the first trimester who presented to the ED with abdominal pain or vaginal bleeding. Patients received pelvic ultrasonography, serum β-hCG testing, and blinded formal radiologic ultrasonography. All patients were followed for 8 weeks to determine outcomes. The sensitivity and specificity of a discriminatory β-hCG level of 3,000 mIU/mL for the diagnosis of ectopic pregnancy were calculated for patients without an intrauterine pregnancy visualized by bedside ultrasonography. RESULTS Thirty-six faculty physicians performed bedside pelvic ultrasonography on 256 patients. There were 161 cases with a confirmed visualizable intrauterine pregnancy and 29 ectopic pregnancies. Bedside ultrasonography identified 115 intrauterine pregnancies. The range of β-hCG for cases of confirmed visualizable intrauterine pregnancy with a nondiagnostic bedside ultrasonography was 15 mIU/mL to 123,368 mIU/mL (median 6,633; interquartile range 1,551 to 32,699). For patients with nondiagnostic bedside ultrasonography, using a discriminatory β-hCG level of 3,000 mIU/mL to further assess for ectopic pregnancy showed sensitivity of 35% (95% confidence interval [CI] 18% to 54%) and specificity of 58% (95% CI 48% to 67%). Finally, the overall sensitivity of bedside pelvic ultrasonography for the detection of intrauterine pregnancy was 71% (95% CI 63% to 78%), and the specificity was 99% (95% CI 94% to 100%). CONCLUSION When bedside pelvic ultrasonography does not demonstrate an intrauterine pregnancy, serum β-hCG level is not helpful in differentiating intrauterine from ectopic pregnancy in symptomatic ED patients.

Abstract
Ectopic pregnancy is a common condition with the immediate risk of life-threatening hemorrhage and subsequent risks of infertility and recurrence. Despite remarkable advances in diagnosis and treatment, ectopic pregnancies account for 9% of all maternal deaths. Early diagnosis has led to the development of innovative surgical and nonsurgical options. The choice of treatment, including expectant, medical, and surgical approaches, depends on ectopic location, symptoms, gestational age, and future fertility desires. Goals are to make the diagnosis of ectopic pregnancy early and provide the most effective and least invasive procedure while sparing future fertility when desired.

Abstract
OBJECTIVE Symptoms of vaginal bleeding and abdominal pain are common in cases of ectopic pregnancy (EP), spontaneous abortions (SAB), and complications of an intrauterine pregnancy (IUP). It is important to determine if efforts should focus on differentiating EP from an IUP (IUP + SAB) or a viable IUP from a nonviable gestation (EP + SAB) in women at risk for EP. METHODS This is a retrospective cohort study of women who presented with bleeding or pain or both during the first trimester of pregnancy. The cohort was divided into subjects diagnosed with IUP vs. (EP + SAB). The same cohort was then divided into subjects diagnosed with EP vs. (IUP + SAB). Logistic regression models based on risk factors for both outcomes (EP vs. [IUP + SAB] and IUP vs. [EP + SAB]) were obtained. ROC curves as well as Hosmer-Lemeshow goodness of fit and Akaike's information criterion (AIC) were used. RESULTS Overall, 18.1% (n = 367) of the women were diagnosed with EP, 58.8% (n = 1192) were diagnosed with an SAB, and 23.1% (n = 467) had an ongoing IUP. The area under the ROC curve for the model IUP vs. (EP + SAB) was statistically greater than the model EP vs. (IUP + SAB), p < 0.001. AIC and Hosmer-Lemeshow goodness of fit confirmed the better accuracy of the model comparing IUP vs. (EP + SAB). CONCLUSIONS Information collected at initial presentation from women at risk for EP to be used for building prediction rules should focus on differentiating a viable from a nonviable pregnancy rather than attempting to distinguish an extrauterine from an intrauterine pregnancy. However, this distinction should not affect current clinical care.

Abstract
Ectopic pregnancy is a life-threatening emergency, the incidence of which is increasing globally. There are a number of factors predisposing to this condition; today, the most common of these is salpingitis. Due to advancements in diagnostic technology it is possible to diagnose this condition early and thus try to achieve a favourable outcome for the patient. Treatment options in the form of medical and surgical modalities are widely available. As minimally invasive therapy techniques are rapidly advancing, laparoscopic treatment has become the most popular and preferred method for treating ectopic pregnancy. Both salpingotomy as well as salpingectomy can be performed through the laparoscope. This paper gives a short glimpse at the predisposing factors and the diagnostic investigations available for ectopic pregnancy and an insight into its laparoscopic treatment. It also reviews the pregnancy outcome and laparoscopic treatment of cases at the Department of Obstetrics and Gynaecology, Campus Kiel, University Hospitals Schleswig-Holstein.

Abstract
BACKGROUND Early pregnancy assessment clinics (EPAC) have been introduced and accepted as the gold standard for management of early pregnancy problems (EPP). However, EPAC are not universally available and management of EPP within the emergency department (ED) can result in prolonged waiting times, inappropriate use of resources and no clear treatment or follow-up plan being implemented. AIM To assess the effect of an early pregnancy assessment protocol (EPAP) in the ED, designed to create a cultural change among doctors in relation to EPP in order to minimise use of resources, improve treatment times for patients and establish a clear management plan where dedicated EPAC services are not available. METHODS An intervention, the EPAP was introduced to the ED and retrospective and prospective audits of the patients were carried out to assess the effect. RESULTS Implementation of the EPAP decreased treatment time by 55%, representations by 48%, pathology blood tests by 56% and formal imaging services by 85%. Gynaecological consultation increased by 37% for each patient visit to the ED and by 9% for each EPP. Total direct cost saving was 63% per patient and no adverse outcomes were recorded. CONCLUSION Introduction of the EPAP was successful in creating cultural change and delivering clinical and financial benefits to the hospital, patients and staff. Early gynaecological consultation and bedside ultrasound scanning within the ED were key factors. Similar benefits could be reproduced in other institutions and for other clinical scenarios where a need has been identified.

Abstract
Bedside emergency ultrasound has been used by emergency physicians for >20 years for a variety of conditions. In adult centers, emergency ultrasound is routinely used in the management of victims of blunt abdominal trauma, in patients with abdominal aortic aneurysm and biliary disease, and in women with first-trimester pregnancy complications. Although its use has grown dramatically in the last decade in adult emergency departments, only recently has this tool been embraced by pediatric emergency physicians. As the modality advances and becomes more available, it will be important for primary care pediatricians to understand its uses and limitations and to ensure that pediatric emergency physicians have access to the proper training, equipment, and experience. This article is meant to review the current literature relating to emergency ultrasound in pediatric emergency medicine, as well as to describe potential pediatric applications.

Abstract
We describe a woman who presented to the Emergency Department (ED) with vaginal bleeding and abdominal pain. She was initially diagnosed by the emergency physician with a molar pregnancy by transvaginal ultrasound, which was confirmed and treated by the consulting obstetrical service with a dilatation and curettage the following day. The patient was discharged home later that same day and subsequently returned to the ED after several hours complaining of an acute worsening of her abdominal pain with associated fatigue and lightheadedness. Transabdominal ultrasound performed by the emergency physician demonstrated intra-abdominal free fluid, and the obstetrical service was immediately contacted. Subsequent operative management identified a separate ruptured ectopic pregnancy in the fallopian tube that was confirmed by pathologic analysis after laparoscopic removal.

Abstract
OBJECTIVE To analyze serial human chorionic gonadotropin (hCG) levels in women presenting to the emergency department who were ultimately confirmed to have ectopic pregnancies. METHODS Human chorionic gonadotropin levels were obtained over time until definitive diagnosis. To be included, women had to have at least 2 hCG measurements. Human chorionic gonadotropin curves were characterized and their slopes calculated. RESULTS Two hundred women received diagnoses of ectopic pregnancy with the help of serial hCG values and were included in the study. No curve adequately characterized the pattern of hCG values so attention was focused on the initial 2 values. The median slope of log hCG among all subjects was 0.11 (25% increase in 2 days). However, 60% of subjects had an initial rise in hCG, and 40% had an initial fall. The rise in hCG for women with ectopic pregnancies (0.28; 75% increase in 2 days) was slower than the mean increase reported for a viable intrauterine pregnancy. The decline in hCG for women with ectopic pregnancies (-0.225; 27% decline in 2 days) was slower than the mean reported for completed spontaneous abortion. However, 20.8% of women presented with a rise in hCG values similar to the minimal rise for women with a viable gestation, and 8% of women presented with a fall in hCG values similar to women with a completed spontaneous abortion. CONCLUSION There is no single way to characterize the pattern of hCG for ectopic pregnancy. The number of women with ectopic pregnancy who experience an increase in hCG values is approximately equal to the number of those who experience a decrease. The hCG profile in women with ectopic pregnancy can mimic that of an intrauterine pregnancy or a completed spontaneous abortion in approximately 29% of cases. LEVEL OF EVIDENCE II-2.

Abstract
Background To derive an ultrasound-based prediction model for the quantification of haemoperitoneum in ectopic pregnancy (EP). Methods Retrospective study of 89 patients operated upon EP between January 1999 and March 2003 in a French Gynaecology and Obstetrics department in a university hospital. Transvaginal sonograms, clinical and biological variables from patients with haemoperitoneum ≥ 300 ml at surgery were compared with those from patients with haemoperitoneum < 300 ml or no haemoperitoneum. Sensitivity, specificity, positive and negative likelihood ratios were calculated for each parameter after appropriate dichotomization. Multiple logistic regression analysis was used to select the best combination at predicting haemoperitoneum ≥ 300 ml. Results Three parameters predicted haemoperitoneum ≥ 300 ml independently: moderate to severe spontaneous pelvic pain, fluid above the uterine fundus or around the ovary at transvaginal ultrasound, and serum haemoglobin concentration < 10 g/dL. A woman with none of these three criteria would have a probability of 5.3% for haemoperitoneum ≥ 300 ml. When two or more criterias were present, the probability for haemoperitoneum ≥ 300 ml reached 92.6%. Conclusion The proposed model accurately predicted significant haemoperitoneum in patients diagnosed to have EP.
