Relationship between extreme values of first trimester maternal pregnancy associated plasma Protein-A, free-ß-human chorionic gonadotropin, nuchal translucency and adverse pregnancy outcomes.

OBJECTIVE: The aim of our study was to investigate the relationship between extreme values of first trimester screening markers and adverse obstetric outcomes. MATERIALS AND METHODS: Our study was conducted by examining the prenatal and postnatal perinatal records of 786 singleton gestations between the ages of 18-40, who applied to Prof. Dr. Cemil Tasçioglu City Hospital outpatient clinics for first-trimester screening for aneuploidy, between January 1, 2017 and December 31, 2019. RESULTS: The presence of small for gestational age (SGA) was found to be statistically significant for the <5 percentile (<0.37) pregnancy-associated plasma protein A (PAPP-A) group (p = 0.016). For <5 percentile ß-hCG group, the presence of gestational diabetes mellitus (GDM), premature rupture of membrane (PROM) and preterm premature rupture of membrane (PPROM) was determined as a statistically significant risk (p = 0.015, p = 0.005, p = 0.02 respectively) In the univariate test, fetal death rate was found to be high for ≥90 percentile at nuchal translucency (NT), but the presence of fetal death was found to be statistically insignificant in logistic regression analysis. (p: 0.057). CONCLUSION: First trimester screening test can be used in predicting pregnancy complications. In this study we found that serum levels of PAPP-A are associated with developing SGA, while GDM, PROM and PPROM are more common in low serum free ß-hCG.

A rare case presentation: pregnancy and gastric carcinoma.

BACKGROUND: Gastrointestinal system (GIS) malignancy with pregnancy is a very rare condition and is not common outside Japan. The incidence is between 0.025-0.1% for each pregnancy. GIS malignancies are diagnosed late in pregnancy and detected at an advanced stage. The most common cause of this condition is that the symptoms such as vomiting, nausea, loss of appetite and abdominal growth are mistaken with pregnancy and malignancy is overlooked. Especially in the second trimester, symptoms such as nausea and vomiting, weight loss, melena, hematemesis and deep anemia should suggest malignancy. Upper GIS endoscopy and colonoscopy are the recommended screening methods in these patients, especially in the third trimester. CASE PRESENTATION: We present a rare case presenting to our emergency room with the complaint of bloody vomiting, at the 36th week of gestation with a live singleton pregnancy, and receiving the diagnosis of undifferentiated gastric carcinoma from the biopsy taken from the ulcerated lesion on the stomach cardia, with upper GIS endoscopy performed due to deep anemia, who underwent simultaneous cesarean section and subtotal gastrectomy. CONCLUSION: Gastrointestinal system (GIS) malignancy with pregnancy is a very rare condition, but it should be considered when symptoms such as nausea and vomiting, weight loss, melena, hematemesis and deep anemia occur, especially in the second trimester, and endoscopic screening should be recommended. Because of the delay in diagnosis of malignancy and the detection in advanced stages, patients should be referred for treatment without delay.
