The beta subunit of human CHORIONIC GONADOTROPIN. Its structure is similar to the beta subunit of LUTEINIZING HORMONE, except for the additional 30 amino acids at the carboxy end with the associated carbohydrate residues. HCG-beta is used as a diagnostic marker for early detection of pregnancy, spontaneous abortion (ABORTION, SPONTANEOUS); ECTOPIC PREGNANCY; HYDATIDIFORM MOLE; CHORIOCARCINOMA; or DOWN SYNDROME.
A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).
A malignant metastatic form of trophoblastic tumors. Unlike the HYDATIDIFORM MOLE, choriocarcinoma contains no CHORIONIC VILLI but rather sheets of undifferentiated cytotrophoblasts and syncytiotrophoblasts (TROPHOBLASTS). It is characterized by the large amounts of CHORIONIC GONADOTROPIN produced. Tissue origins can be determined by DNA analyses: placental (fetal) origin or non-placental origin (CHORIOCARCINOMA, NON-GESTATIONAL).
Chemical groups containing the covalent disulfide bonds -S-S-. The sulfur atoms can be bound to inorganic or organic moieties.
The alpha chain of pituitary glycoprotein hormones (THYROTROPIN; FOLLICLE STIMULATING HORMONE; LUTEINIZING HORMONE) and the placental CHORIONIC GONADOTROPIN. Within a species, the alpha subunits of these four hormones are identical; the distinct functional characteristics of these glycoprotein hormones are determined by the unique beta subunits. Both subunits, the non-covalently bound heterodimers, are required for full biologic activity.
Partial proteins formed by partial hydrolysis of complete proteins or generated through PROTEIN ENGINEERING techniques.
Hormones that stimulate gonadal functions such as GAMETOGENESIS and sex steroid hormone production in the OVARY and the TESTIS. Major gonadotropins are glycoproteins produced primarily by the adenohypophysis (GONADOTROPINS, PITUITARY) and the placenta (CHORIONIC GONADOTROPIN). In some species, pituitary PROLACTIN and PLACENTAL LACTOGEN exert some luteotropic activities.
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Luteinizing hormone regulates steroid production by the interstitial cells of the TESTIS and the OVARY. The preovulatory LUTEINIZING HORMONE surge in females induces OVULATION, and subsequent LUTEINIZATION of the follicle. LUTEINIZING HORMONE consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH and FSH), but the beta subunit is unique and confers its biological specificity.
Those protein complexes or molecular sites on the surfaces and cytoplasm of gonadal cells that bind luteinizing or chorionic gonadotropic hormones and thereby cause the gonadal cells to synthesize and secrete sex steroids. The hormone-receptor complex is internalized from the plasma membrane and initiates steroid synthesis.
Gonadotropins secreted by the pituitary or the placenta in horses. This term generally refers to the gonadotropins found in the pregnant mare serum, a rich source of equine CHORIONIC GONADOTROPIN; LUTEINIZING HORMONE; and FOLLICLE STIMULATING HORMONE. Unlike that in humans, the equine LUTEINIZING HORMONE, BETA SUBUNIT is identical to the equine choronic gonadotropin, beta. Equine gonadotropins prepared from pregnant mare serum are used in reproductive studies.
Those protein complexes or molecular sites on the surfaces of gonadal and other sensitive cells that bind gonadotropins and thereby modify the functions of those cells; hCG, LH, and FOLLICLE STIMULATING HORMONE are the major specific gonadotropins.
A major gonadotropin secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.
Hormones secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR) that stimulate gonadal functions in both males and females. They include FOLLICLE STIMULATING HORMONE that stimulates germ cell maturation (OOGENESIS; SPERMATOGENESIS), and LUTEINIZING HORMONE that stimulates the production of sex steroids (ESTROGENS; PROGESTERONE; ANDROGENS).
Lists of words, usually in alphabetical order, giving information about form, pronunciation, etymology, grammar, and meaning.
Molecular products metabolized and secreted by neoplastic tissue and characterized biochemically in cells or body fluids. They are indicators of tumor stage and grade as well as useful for monitoring responses to treatment and predicting recurrence.

A group of diseases arising from pregnancy that are commonly associated with hyperplasia of trophoblasts (TROPHOBLAST) and markedly elevated human CHORIONIC GONADOTROPIN. They include HYDATIDIFORM MOLE, invasive mole (HYDATIDIFORM MOLE, INVASIVE), placental-site trophoblastic tumor (TROPHOBLASTIC TUMOR, PLACENTAL SITE), and CHORIOCARCINOMA. These neoplasms have varying propensities for invasion and spread.
Trophoblastic growth, which may be gestational or nongestational in origin. Trophoblastic neoplasia resulting from pregnancy is often described as gestational trophoblastic disease to distinguish it from germ cell tumors which frequently show trophoblastic elements, and from the trophoblastic differentiation which sometimes occurs in a wide variety of epithelial cancers. Gestational trophoblastic growth has several forms, including HYDATIDIFORM MOLE and CHORIOCARCINOMA. (From Holland et al., Cancer Medicine, 3d ed, p1691)
Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.

A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.

A common neoplasm of early childhood arising from neural crest cells in the sympathetic nervous system, and characterized by diverse clinical behavior, ranging from spontaneous remission to rapid metastatic progression and death. This tumor is the most common intraabdominal malignancy of childhood, but it may also arise from thorax, neck, or rarely occur in the central nervous system. Histologic features include uniform round cells with hyperchromatic nuclei arranged in nests and separated by fibrovascular septa. Neuroblastomas may be associated with the opsoclonus-myoclonus syndrome. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, pp2099-2101; Curr Opin Oncol 1998 Jan;10(1):43-51)
A radiosensitive, malignant neoplasm of the testis, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. There are three variants: classical (typical), the most common type; anaplastic; and spermatocytic. The classical seminoma is composed of fairly well differentiated sheets or cords of uniform polygonal or round cells (seminoma cells), each cell having abundant clear cytoplasm, distinct cell membranes, a centrally placed round nucleus, and one or more nucleoli. In the female, a grossly and histologically identical neoplasm, known as dysgerminoma, occurs. (Dorland, 27th ed)
A malignant ovarian neoplasm, thought to be derived from primordial germ cells of the sexually undifferentiated embryonic gonad. It is the counterpart of the classical seminoma of the testis, to which it is both grossly and histologically identical. Dysgerminomas comprise 16% of all germ cell tumors but are rare before the age of 10, although nearly 50% occur before the age of 20. They are generally considered of low-grade malignancy but may spread if the tumor extends through its capsule and involves lymph nodes or blood vessels. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1646)

The effectiveness of non-surgical management of early interstitial pregnancy: a report of ten cases and review of the literature. (1/497)

OBJECTIVE: To assess the effectiveness of non-surgical management of interstitial pregnancy. DESIGN: A prospective interventional study. SUBJECTS: Eleven women with the ultrasound diagnosis of interstitial ectopic pregnancy. METHODS: Women with suspected early pregnancy complications were examined by transvaginal ultrasound. Those with the diagnosis of interstitial pregnancy were offered non-surgical treatment with methotrexate, which was administered systemically or by local injection. Follow-up with regular measurements of beta-human chorionic gonadotropin and ultrasound scans continued until the pregnancy had resolved completely. RESULTS: Ten women were managed non-surgically, and one woman opted for surgery. Five women received systemic and five local methotrexate. Local therapy was successful in all five cases (100%), whereas four out of five (80%) women receiving systemic methotrexate were cured. Significant side-effects were noted in two women following systemic therapy. In comparison, there were no side-effects in the group of women who received local therapy. There were no significant differences between the two treatment groups in the length of time taken for the pregnancy to resolve. CONCLUSIONS: Non-surgical treatment of interstitial pregnancy with methotrexate appears to be safe and effective. Local administration appears to be more successful and better tolerated by patients and may be used as the first-line therapy.  (+info)

Combined treatment modality for intracranial germinomas: results of a multicentre SFOP experience. Societe Francaise d'Oncologie Pediatrique. (2/497)

Conventional therapy for intracranial germinomas is craniospinal irradiation. In 1990, the Societe Francaise d'Oncologie Pediatrique initiated a study combining chemotherapy (alternating courses of etoposide-carboplatin and etoposide-ifosfamide for a recommended total of four courses) with 40 Gy local irradiation for patients with localized germinomas. Metastatic patients were allocated to receive low-dose craniospinal radiotherapy. Fifty-seven patients were enrolled between 1990 and 1996. Forty-seven had biopsy-proven germinoma. Biopsy was not performed in ten patients (four had diagnostic tumour markers and in six the neurosurgeon felt biopsy was contraindicated). Fifty-one patients had localized disease, and six leptomeningeal dissemination. Seven patients had bifocal tumour. All but one patient received at least four courses of chemotherapy. Toxicity was mainly haematological. Patients with diabetus insipidus (n = 25) commonly developed electrolyte disturbances during chemotherapy. No patient developed tumour progression during chemotherapy. Fifty patients received local radiotherapy with a median dose of 40 Gy to the initial tumour volume. Six metastatic patients, and one patient with localized disease who stopped chemotherapy due to severe toxicity, received craniospinal radiotherapy. The median follow-up for the group was 42 months. Four patients relapsed 9, 10, 38 and 57 months after diagnosis. Three achieved second complete remission following salvage treatment with chemotherapy alone or chemo-radiotherapy. The estimated 3-year survival probability is 98% (CI: 86.6-99.7%) and the estimated 3-year event-free survival is 96.4% (CI: 86.2-99.1%). This study shows that excellent survival rates can be achieved by combining chemotherapy and local radiotherapy in patients with non-metastatic intracranial germinomas.  (+info)

Hyperreactio luteinalis associated with chronic renal failure. (3/497)

Hyperreactio luteinalis is a rare benign condition characterized by bilateral ovarian enlargement associated with pregnancies where high concentrations of maternal serum human chorionic gonadotrophins are present. This condition may mimic the ovarian hyperstimulation syndrome. We report a case of a 34 year old woman with a history of chronic renal failure on haemodialysis who presented at 10 weeks' gestational age with hyperreactio luteinalis which was treated conservatively. Because of chronic renal failure, the presentation and course of the disease was different from that which has been previously reported.  (+info)

Characterization of human placental explants: morphological, biochemical and physiological studies using first and third trimester placenta. (4/497)

The primary objective of this study was to characterize an in-vitro model of the human placenta using morphological, biochemical and physiological parameters. Placental villi were obtained from normal first trimester and term pregnancies. The villi were incubated with Dulbecco's modified Eagle's medium: Ham's F12 nutrient mixture in a shaking water bath at 37 degrees C for up to 310 min. The viability was determined by the production of beta human chorionic gonadotrophin (HCG) and lactic dehydrogenase (LDH) and the incorporation of [3H]thymidine, [3H]L-leucine and L-[U14C]arginine, while ultrastructure was assessed by transmission electron microscopy. In the first and third trimester group, the release into the medium of the intracellular enzyme LDH remained unaltered throughout the experiment. By contrast, beta-HCG concentrations increased linearly and concentrations were higher in the first trimester than term villi (354.5 +/- 37.8 versus 107 +/- 8.1 IU/g villi protein; P < 0.001). Electron microscopy confirmed preservation of tissue viability for up to 4 h of incubation. The incorporation of thymidine (12.2 +/- 2.9 versus 5.2 +/- 0.5 nmol/g villi protein; P < 0.05), leucine (9.4 +/- 2.1 versus 1.9 +/- 0.4 nmol/g villi protein; P < 0.02) and arginine (17 +/- 4.4 versus 4.2 +/- 0.5 nmol/g villi protein; P < 0.05) were markedly higher in early than in term placenta. Furthermore, placental uptake of L-leucine by the first (9.4 +/- 2.1 versus 17 + 4.4 mol/g villi protein; P < 0.001) and third trimester placental villi (1.9 +/- 0.4 versus 4.2 + 0.5 mol/g villi protein; P < 0.001) was less than that of L-arginine. This study describes a simple technique using placental explants to determine relative rates of uptake of substrate amino acids throughout gestation.  (+info)

Cross-reaction with luteinizing hormone beta-core is responsible for the age-dependent increase of immunoreactive beta-core fragment of human chorionic gonadotropin in women with nonmalignant conditions. (5/497)

BACKGROUND: The beta-core fragment of human chorionic gonadotropin (hCGbetacf), also termed "beta-core" and urinary gonadotropin peptide (UGP), has been reported to be present in the urine of healthy women and to increase in concentration after menopause. This could reflect cross-reaction with the equivalent metabolite of luteinizing hormone (LH), the beta-LH-core. METHODS: We measured immunoreactive LH, hCG, free alpha-subunit, and free beta-subunit hCG (hCGbeta), as well as beta-core, using the S504 RIA and Triton UGP enzyme immunoassay in 274 urine samples from women with nonmalignant gynecological conditions. The molar cross-reaction of each assay with purified beta-LH-core was determined. RESULTS: Cross-reaction with beta-LH-core was 100% in the LH and the S504 beta-core assay, 5% in the Triton UGP assay, and <0.1% in the hCG, free alpha-subunit, and free hCGbeta assays. Median urine concentrations of all analytes showed an age-dependent increase. LH and free alpha-subunit concentrations were approximately 10(3) pmol/mol creatinine; hCG and S504 beta-core were approximately 10(2) pmol/mol creatinine; free hCGbeta and Triton UGP beta-core were in the tens of pmol/mol creatinine. The S504 beta-core concentrations were 10% of those of LH. S504 beta-core was strongly correlated with LH, but not with hCG or with free hCGbeta (LH, r2 = 0.45; hCG, r2 = 0.26; free hCGbeta, r2 = 0.03). The concentrations of beta-core detected by the Triton UGP assay, which has a 5% cross-reaction with beta-LH-core, were 2% of LH and 5% of the S504 beta-core concentrations. Triton UGP values correlated strongly with LH concentrations, but less well with S504 beta-core, intact hCG, and free hCGbeta (LH, r2 = 0.44; S504 beta-core, r2 = 0.33; hCG, r2 = 0.32; free hCGbeta, r2 = 0.19). CONCLUSIONS: Immunoreactive beta-core in women free of malignancies reflects cross-reaction with concentrations of the metabolite of LH, beta-LH-core, within the health-related reference interval.  (+info)

Perinatal outcome in pregnancies with a positive serum screening for Down's syndrome due to elevated levels of free beta-human chorionic gonadotropin. (6/497)

OBJECTIVE: To evaluate the potential clinical use of maternal serum free beta-human chorionic gonadotropin (beta-hCG) and uterine artery Doppler investigation to screen for placenta-related adverse outcome in pregnancies at positive risk for Down's syndrome at 15-18 weeks. DESIGN: A cohort of 329 consecutive pregnant women with a singleton viable pregnancy and a positive risk for Down's syndrome was retrospectively investigated. This group was obtained from an unselected population of 3952 women attending the same hospital over a 2-year period. Using the results of this first analysis, we selected a group of 26 women with unexplained high levels of free beta-hCG and followed them prospectively with monthly ultrasound and uterine artery Doppler examinations. RESULTS: In the retrospective cohort, risk ratios stratified for maternal serum beta-hCG multiple of the median (MoM) values indicated that the highest incidence of adverse pregnancy outcome was in those women with values of > or = 5.0. In the prospective study, pregnancy outcome was complicated by uteroplacental disorders in eight cases. Analysis of the Doppler investigation indicated that, in women with a very high level of hCG, an abnormally high uterine artery pulsatility index (PI) had lower sensitivity and negative predictive value than early diastolic notch, whereas the specificity and positive predictive value were higher for a high uterine artery PI. CONCLUSIONS: These findings suggest an association between a high level of maternal serum beta-hCG at 15-18 weeks, the presence of an early diastolic notch in the uterine artery flow velocity waveform and adverse pregnancy outcome due to abnormal development of the uteroplacental circulation. Young women with an unexplained high beta-hCG level would benefit, apart from detailed sonography of the fetus and/or karyotyping, from uterine Doppler investigation and counselling about the follow-up and management of placenta-related pregnancy disorders.  (+info)

Arteriovenous malformation of mesosalpinx associated with a 'vanishing' ectopic pregnancy: diagnosis with three-dimensional color power angiography. (7/497)

We describe two cases of pelvic arteriovenous malformation diagnosed with the aid of three-dimensional color power angiography. In both cases, beta-human chorionic gonadotropin (beta-hCG) increased to significant levels (8413 and 1560 mIU/ml, respectively); however, neither an intrauterine nor an adnexal gestational sac could be found. In each case, we observed an adnexal mass with several tortuous areas exhibiting abundant turbulent flow. The diagnosis of arteriovenous malformation was made and further assessment by three-dimensional color power angiography and magnetic resonance imaging (MRI) was carried out. The complex vascular anatomy of arteriovenous malformation, including its feeding vessels and drainage, was clearly depicted by three-dimensional color power angiography and correlated well with magnetic resonance angiography. Levels of beta-hCG decreased in subsequent tests, and eventually became negative 2-3 months later without and intervention. We believe that an involutional ectopic pregnancy induced the rapid growth of the arteriovenous malformations within the mesosalpinx. Three-dimensional color power angiography can be performed quickly and easily, using existing ultrasound equipment. It improves our understanding of complicated vasculature, and thus is a useful adjunct to two-dimensional and color Doppler ultrasound in the diagnosis of arteriovenous malformation.  (+info)

Cervical pregnancy--a conservative stepwise approach. (8/497)

A case of cervical pregnancy resistant to intramuscular methotrexate therapy is presented, which was successfully treated by intra-arterial methotrexate followed by selective prophylactic hypogastric artery embolization to avoid aggravating the vaginal bleeding. It is suggested that, in cervical pregnancies in which fertility preservation is desired, a stepwise conservative approach should be applied before resorting to surgical intervention.  (+info)

BACKGROUND Medical treatment of the rare interstitial ectopic pregnancy with methotrexate has been considered an alternative to surgical resection. AIM To determine the treatment success rate with a single-dose intravenous methotrexate/folinic acid regimen and to identify predictors of treatment outcome. METHODS A 5-year audit (April 2000-August 2005) was carried out, collecting clinical imaging data and serum beta-human chorionic gonadotrophin (beta-hCG). Time taken for complete beta-hCG resolution was recorded, and a negative beta-hCG result was used as an endpoint of successful outcome. RESULTS Of the 13 cases, two required urgent surgery for rupture on presentation. In the remaining 11 cases, intravenous methotrexate (300 mg) was used, with oral folinic acid rescue (15 mg x 4 doses). There were no side-effects. Complete beta-hCG resolution was achieved in 10 of the 11 medically treated cases (91% success rate), requiring 21-129 days. Successful outcome was seen with initial beta-hCG level as

Beta hCG Test Definition - A beta hCG test is a blood test that monitors levels of the hormone human chorionic gonadotropin (hCG) present in the body....
HCG levels are often measured as part of a maternal serum triple or quadruple screening test. These tests are done by measuring three or four substances in a womans blood and are used to estimate the babys risk of certain problems or congenital birth defects. The triple screen measures beta human chorionic gonadotropin (beta-HCG), alpha-fetoprotein (AFP), and a type of estrogen (unconjugated estriol or uE3). The quad screen measures the hormone inhibin-A in addition to the other three.. Abnormal HCG levels do not necessarily mean that there is a problem. It could simply be due to a miscalculation of pregnancy dating. Unfortunately though, abnormal HCG levels could also indicate a more serious issue. There are several things that could cause a high or low HCG level, so you should be retested within a few days to see how the levels are changing.. A high HCG level could be an indicator of a multiple pregnancy, in which there is more than one fetus present, or a molar pregnancy. A low HCG level ...

Thyrocare BETA HCG in Kolkata is health checkup package includes 1 Tests. Home sample collection and Online reports available. BETA HCG in Kolkata covers 1 parameters-
Human chorionic gonadotropin (hCG) is a glycoprotein hormone (molecular weight: MW approximately 36,000 Dalton: Da) consisting of 2 noncovalently bound subunits. The alpha subunit (92-amino acids; naked protein MW 10,205 Da) is essentially identical to that of luteinizing hormone (LH), follicle-stimulating hormone, and thyroid-stimulating hormone (TSH). The alpha subunit is essential for receptor transactivation. The different beta subunits of the above hormones are transcribed from separate genes, show less homology, and convey the receptor-specificity of the dimeric hormones. The chorionic gonadotropin, beta gene (coding for a 145-amino acid, naked protein MW 15,531 Da, glycosylated subunit MW approximately 22,500 Da) is highly homologous to the beta subunit of LH and acts through the same receptor. However, while LH is a classical tropic pituitary hormone, hCG does not usually circulate in significant concentrations. In pregnant primates (including humans) it is synthesized in the ...

This hormone, absent in the unfertilized woman, is traceable about eight days after fertilization ...
This past month could have produced a tension filled, emotionally charged blog to follow. I didnt have the heart to do it. At 5 weeks 3 days I started bleeding. A gush of blood in the toilet. My OB had me go in to her office for a urine test, and a beta hcg draw. My HCG number was fine. It had doubled up as expected from the previous draw at 15 days past ovulation. My urine tested clear for infection. I was sent home. Another small gush of blood as I was preparing steaks for the oven that evening. My husband came home and we took a taxi to the hospital. My HMO has recently consolidated its former 2 emergency rooms to one. The waiting room was packed with about 50 people. I was triage after about an hour and a half. Nobody was being called back. More people kept checking in. I was seen by a doctor nearly 7 hours after I arrived. By that time I was hungry and terrified that I was losing my pregnancy. An ultrasound showed nothing visible in my uterus. There should have been a measurable sac. The ...

OBJECTIVES: To evaluate the performance of first-trimester screening for trisomy 21 by a combination of maternal age, fetal nuchal translucency (NT) and maternal serum free beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A). In addition, the potential impact of a new individual risk-orientated two-stage approach to first-trimester screening was ...
Gestational choriocarcinoma usually arises in the uterine cavity and is associated with coincident or antecedent pregnancy. Extrauterine choriocarcinomas are very rare entities, and most of these are located in the uterine cervix. In our case, a 43-year-old woman was admitted in our hospital because she had amenorrhea for 2 months and elevated serum beta-human chorionic gonadotropin levels. The patient was considered to have an ectopic pregnancy. Initially, she was treated with methotrexate, but since there was a continuous rise in human chorionic gonadotropin levels, the patient underwent a laparoscopy, along with dilatation and curettage (D&C) of the uterine cavity. Histopathologic findings, including immunohistochemical study, led to the diagnosis of choriocarcinoma of the cervix. Finally, the patient underwent a transabdominal hysterectomy and received single agent chemotherapy with methotrexate. Our case represents a primary choriocarcinoma of the cervix, which was initially misdiagnosed as ...
Objective To establish an algorithm for first-trimester combined screening for trisomy 21 with biochemical testing from 7 to 14 weeks gestation and ultrasound testing at 11-13 weeks. Methods This was a multicenter study of 886 pregnancies with trisomy 21 and 222 475 unaffected pregnancies with measurements of free beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A) at 7-14 weeks gestation. Multiple regression modeling of log-transformed marker values was used to produce log multiples of the median (MoM) values for PAPP-A and free beta-hCG. The models included terms for the center attended and the machine used for biochemical analysis, gestational age, maternal racial origin, maternal weight, smoking status and method of conception. Bivariate Gaussian distributions were fitted to log MoM PAPP-A and log MoM free beta-hCG in trisomy 21 and in unaffected pregnancies. In each case the patient-specific risk for trisomy 21 was estimated by multiplying the ...

Our purpose was to determine the association between unexplained elevation of maternal serum human chorionic gonadotropin (hCG) in the second trimester and adverse pregnancy outcomes. MATERIAL AND METHODS: Between February 1995 and July 1999, we evaluated 1566 pregnant women who have underwent second trimester triple marker screening tests (alpha-fetoprotein, unconjugated estriol, human chorionic gonadotropin) and delivered at Severance Hospital, Yonsei Medical Center. Multiple pregnancies, abnormal fetal karyotypes, fetal anomalies, and abortions were excluded from the study. One hundred twenty-one women with hCG levels greater than 2.0 multiples of the median (MoM) were included in the study group while 1389 women with hCG levels less than 2.0 MoM served as the control group. Pregnancy outcomes were obtained from the delivery and neonatal records in our institution. Adverse pregnancy outcomes between the two groups were compared using chi-square test and Fishers exact test. RESULTS: Women ...
TY - JOUR. T1 - Clinical evaluation of human chorionic gonadotropin levels in men with testicular tumors. AU - Cochran, J. S.. AU - Walsh, P. C.. AU - Porter, J. C.. PY - 1974/1/1. Y1 - 1974/1/1. N2 - In patients with testicular tumor, HCG β serves as a sensitive, specific marker of tumor activity. Because HCG β levels correlate well with response to therapy, this test may be useful in selecting men for adjunctive irradiation or chemotherapy. HCG β is far more sensitive and specific than conventional methods for detecting HCG production. Following unilateral orchiectomy for carcinoma of the testis, elevated serum luteinizing hormone levels are common, and may be unrelated to the presence or activity of residual tumor. In this study, 25% of patients with testicular tumors had demonstrable HCG β levels. This test should provide a reliable index for following disease activity and response to therapy.. AB - In patients with testicular tumor, HCG β serves as a sensitive, specific marker of tumor ...

Pregnancy-associated plasma protein-A2 (PAPP-A2, pappalysin-2) is a large metalloproteinase, known to be required for normal postnatal growth and bone development in mice. We here report the detection of zebrafish papp-a2 mRNA in chordamesoderm, notochord, and lower jaw of zebrafish (Danio rerio) embryos, and that papp-a2 knockdown embryos display broadened axial mesoderm, notochord bends, and severely reduced cranial cartilages. Genetic data link these phenotypes to insulin-like growth factor binding protein-3 (Igfbp-3) and Bmp signaling, and biochemical analysis show specific Igfbp-3 proteolysis by Papp-a2, implicating Papp-a2 in the modulation of Bmp signaling by Igfbp-3 proteolysis. Knockdown of papp-a2 additionally resulted in angiogenesis defects, strikingly similar to previous observations in embryos with mutations in components of the Notch system. Concordantly, we find that Notch signaling is modulated by Papp-a2 in vivo, and, furthermore, that PAPP-A2 is capable of modulating Notch ...

Once human chorionic gonadotropin hormone levels are between 1000 and 2000 U/ml a transvaginal ultrasound can be carried out to show the gestational sac. hCG levels can change and the date of conception may be incorrect. When the hCG levels have reached a minimum of 2000 only then would the information from the ultrasound be considered in making a diagnosis.. To make sure that you receive an accurate diagnosis, lots of hCG tests would be carried out over a period of days. By doing the tests a few days apart any questions about the pregnancy will be answered more accurately. Levels of the hCG hormone levels are not used to provide any dates for pregnancy because the numbers are so varied. The two types of human chorionic gonadotropin testings are:. ...

Tests involving 2 markers in combination with maternal age - specifically PAPP-A (pregnancy-associated plasma protein A), free beta-hCG (beta-human chorionic gonadotropin) and maternal age - were significantly better than those involving single markers, with and without age. They detected 7 out of 10 Down-affected pregnancies (3 in 10 were missed), and a fixed 5% of all tested women got a false-positive result. The addition of further markers (triple tests) was not shown to be statistically superior; the studies included were small, with limited power to detect a difference. The screening blood tests themselves had no adverse effects for the woman, over and above the risks of a routine blood test ...
Human chorionic gonadotropin (HCG), a polypeptide hormone produced by the human placenta. HCG is composed of an alpha and a beta sub-unit. The alpha sub-unit is essentially identical to the alpha sub- units of the human pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), as well as to the alpha sub-unit of human thyroid-stimulating hormone (TSH), while the beta sub- units of these hormones differ in amino acid sequence.

The most sensitive, accurate and reliable pregnancy test is a blood test for the presence of beta HCG , often just called beta. The HCG is produced by the embryo, and is the embryos signal to the mother that pregnancy has occurred. Beta HCG levels vary according to the gestational age. In a non-pregnant woman, they are less than 10 mIU/ml. They are typically about 100 mIU/ml 14 days after ovulation (DPO) in a healthy singleton pregnancy.

Some of the tests that were done to diagnose the cancer or to find out the stage of the cancer may be repeated. Some tests will be repeated in order to see how well the treatment is working. Decisions about whether to continue, change, or stop treatment may be based on the results of these tests.. Some of the tests will continue to be done from time to time after treatment has ended. The results of these tests can show if your childs condition has changed or if the cancer has recurred (come back). These tests are sometimes called follow-up tests or check-ups.. For childhood extracranial germ cell tumors, alpha-fetoprotein (AFP) tests and beta-human chorionic gonadotropin (β-hCG) tests are done to see if treatment is working. Continued high levels of AFP or β-hCG may mean the cancer is still growing. For at least 3 years after surgery, follow-up will include regular physical exams, imaging tests, and tumor marker tests.. ...
