Abstract:

Background—Human chorionic gonadotropin (hCG) is normally produced and secreted by trophoblastic cells during pregnancy and from gestational trophoblastic neoplasms. It is also detected in ovarian, stomach, and colon adenocarcinomas, as well as in squamous cell carcinoma of the oesophagus. Recently, interest in its role in the pathogenesis of tumours has been enlivened after the presence of βhCG in the cell membrane of several malignant cells was shown in vitro.Aims—To investigate the circulating concentrations of βhCG in patients with exocrine pancreatic adenocarcinoma and to examine its pote

Abstract:

Background: Point-of-care testing (POCT) provides shorter turn-around times and, in many cases, potentially improves medical decision making. The AQT90 FLEX® benchtop immunoanalyzer (Radiometer Medical ApS, Copenhagen, Denmark) allows for the determination of beta-human chorionic gonadotropin (βhCG) in 18 min. The main aim of this study was to evaluate the impact of measuring βhCG using the AQT90 analyzer in the gynecology emergency department (ED) compared to the standard practice of using central laboratory blood testing on the patient length of stay (LOS). Methods: The evaluation consisted

Abstract:

Background: Gestational trophoblastic disease encompass a spectrum of neoplastic disorders that arise from placental trophoblastic tissue after abnormal fertilisation. Most molar pregnancies spontaneously resolve after uterine evacuation with no further sequelae. However, at any time during or after gestation malignant transformation may occur in approximately 10% to 20% of molar pregnancies. Quantification of βHCG is considered as the ideal method of post molar surveillance. The regression of the disease could be reliably assessed by observing the changes in low resistance flow which parallel

Abstract:

The stability of free βhCG (human chorionic gonadotrophin) was assessed using a dual α-fetoprotein and free βhCG assay. A significant increase in free βhCG concentration was observed in heparinized samples left unseparated for 24 h or more, the mean increase in 21 samples being 10.2% after 24 h ( P = < 0.001), increasing to 45.7% after 96 h. Similar results were also obtained in clotted samples. The effect of the increase in free βhCG on the Down's risk estimate was calculated to assess the impact of delayed sample transport and separation. The Down's risk increased in all samples with incr

Abstract:

Background: Gestational trophoblastic disorders are among the rare human tumors that can be cured even in the presence of widespread dissemination. Authors can anticipate the development of persistent trophoblastic disease by identifying high risk factors affecting βhCG regression in vesicular mole. The study of this aim was to determine the incidence of gestational trophoblastic disorders and persistent trophoblastic disease in our institution. Factors affecting regression of βhCG and thereby leading to persistent disease are assessed.Methods: The study was conducted for a period of 2 years a

Abstract:

We report a retrospective study on serum and cerebrospinal fluid (CSF) alpha-fetoprotein (AFP) and β-human chorionic gonadotropin (βhCG) determination in a series of 30 patients bearing intracranial germ cell tumors. At diagnosis five patients had high serum and CSF AFP levels. No patient had positive serum AFP and negative CSF AFP or vice versa. Twelve of 30 patients had serum βhCG levels above 5 mIU/mL, eight had high βhCG only in CSF, and ten were completely negative. During treatment and follow-up both markers were accurate indicators of the response to therapy, decreasing rapidly and ofte

Abstract The aim of this study was to evaluate the variations in the balance between total (free and combined) circulating α and β subunits of human chorionic gonadotrophin (hCG) in trisomy 21 and 18. Maternal serum samples were collected at 10 and 11 weeks of gestation from 22 singleton pregnancies with trisomy 21 (n=17) and trisomy 18 (n=5) and 66 chromosomally normal controls, matched for gestational age. The hCG and free α and β subunits circulating levels were measured using specific immunoradiometric assays and converted in a common unit system obtained using calibration of the assays wi

Abstract:

Introdução: O conceito de restrição do crescimento fetal tardio (CFT) foi introduzido para descrever fetos com insuficiência placentária que não é grave o suficiente para resultar em CFT com fluxo arterial umbilical anormal, mas é grave o suficiente para associar-se com alto risco perinatal ou complicações de longo prazo. Entretanto, há necessidade de retroceder a investigação para o primeiro trimestre, na esperança de possível intervenção. Objetivo: Realizar revisão bibliográfica do tema.
