Association of low pregnancy associated plasma protein-A with increased umbilical artery pulsatility index in cases of fetal weight between the 3rd and 10th percentiles: a retrospective cohort study.

OBJECTIVES: This study aims to evaluate if low levels of serum maternal pregnancy associated plasma protein-A (PAPP-A) during the first trimester are related to increased umbilical artery pulsatility index (UA PI) later in pregnancy, in cases of estimated fetal weight between the 3rd and 10th percentiles, in order to establish PAPP-A as a predictor of this particular cases of fetal growth restriction (FGR). METHODS: An observational, retrospective cohort study, conducted at a tertiary University Hospital located in Oporto, Portugal. Pregnant women who did the first trimester combined screening, between May 2013 and June 2020 and gave birth in the same hospital, with an estimated fetal weight (EFW) between the 3rd and 10th percentiles were included. The primary outcome is the difference in increased UA PI prevalence between two groups: PAPP-A<0.45 MoM and PAPP-A≥0.45 MoM. As secondary outcomes were evaluated differences in neonatal weight, gestational age at delivery, cesarean delivery, neonatal intensive care unit hospitalization, 5-min Apgar score below 7 and live birth rate between the same two groups. RESULTS: We included 664 pregnancies: 110 cases of PAPP-A<0.45 MoM and 554 cases with PAPP-A≥0.45 MoM. Increased UA PI prevalence, which was the primary outcome of this study, was significantly different between the two groups (p=0.005), as the PAPP-A<0.45 MoM group presents a higher prevalence (12.7 %) when compared to the PAPP-A≥0.45 MoM group (5.4 %). The secondary outcome cesarean delivery rate was significantly different between the groups (p=0.014), as the PAPP-A<0.45 MoM group presents a higher prevalence (42.7 %) than the PAPP-A≥0.45 MoM group (30.1 %). No other secondary outcomes showed differences between the two groups. CONCLUSIONS: There is an association of low serum maternal PAPP-A (<0.45 MoM) during the first trimester and increased UA PI (>95th percentile) later in pregnancy, in cases of EFW between the 3rd and 10th percentiles. However, this association is not strong enough alone for low PAPP-A to be a reliable predictor of increased UA PI in this population.

Fetal lipomyelomeningocele: A closed neural tube defect diagnosed at second-trimester ultrasound examination.

Fetal lipomyelomeningocele was suspected during the second-trimester ultrasound and confirmed by magnetic resonance imaging. The pregnancy took its course and a term neonate was delivered. At 2 years of age lipomyelomeningocele surgical removal was performed. The patient is now 4 years old and, despite neurogenic bladder, is a healthy boy with normal psychomotor development for his age. This case illustrates the favorable prognosis of this entity and the importance of prompt diagnosis and multidisciplinary counseling.

Mature Cystic Teratoma of Ovary with Abnormally High Levels of Ca19-9: A Case Report.

Mature cystic teratomas, or dermoid tumors, are the most common benign ovarian neoplasms in young women. Malignant transformation is rare, and occurs in less than 2% of the cases. The heterogeneous histological composition of these tumors may be responsible for the occasional elevation of various tumor markers, such as Ca19-9 and Ca125. We describe one case of mature cystic teratoma in a 50-year old woman with the second highest level of Ca19-9 (8922.76 UI/mL) described in the literature. We concluded that abnormal levels of Ca19-9 are not necessarily associated with ovarian malignancy, and may lead to unnecessary medical intervention and patient anxiety. Therefore, the clinical features, imaging studies and antigen testing should be interpreted carefully, and should not limit the surgical approach.

Hyperreactio luteinalis encountered during caesarean delivery of an uncomplicated spontaneous singleton pregnancy.

We report a rare case of hyperreactio luteinalis presenting as an incidental finding during caesarean section in an uncomplicated spontaneous singleton pregnancy. Caesarean section was performed due to failure to progress in labour, and delivered a healthy male neonate. The mother's analytical tests revealed a hyperandrogenic state without any other relevant alterations. Ovarian volume and testosterone serum concentration normalised in 2 months. The expectant management of this case permitted conservation of both ovaries in a young woman without adding morbidity.

Mature Cystic Teratoma of Ovary with Abnormally High Levels of Ca19-9: A Case Report / Teratoma maduro cístico do ovário com níveis aberrantes de Ca19-9: caso clínico

Abstract Mature cystic teratomas, or dermoid tumors, are the most common benign ovarian neoplasms in young women. Malignant transformation is rare, and occurs in less than 2% of the cases. The heterogeneous histological composition of these tumors may be responsible for the occasional elevation of various tumor markers, such as Ca19-9 and Ca125. We describe one case of mature cystic teratoma in a 50-year old woman with the second highest level of Ca19-9 (8922.76 UI/mL) described in the literature. We concluded that abnormal levels of Ca19-9 are not necessarily associated with ovarian malignancy, and may lead to unnecessary medical intervention and patient anxiety. Therefore, the clinical features, imaging studies and antigen testing should be interpreted carefully, and should not limit the surgical approach.

Resumo Os teratomas maduros císticos do ovário, ou tumores dermoides, são as neoplasias benignas mais frequentes em mulheres jovens. A sua transformação maligna é rara, e ocorre emmenos de 2% dos casos. A composição histológica heterogénea destes tumores pode ser responsável pela ocasional elevação de marcadores tumorais, como o Ca19-9 e o Ca125. Descrevemos umcaso de teratoma maduro cístico do ovário numa paciente de 50 anos com o segundo valor mais elevado de Ca19-9 (8922,76 UI/mL) descrito na literatura. Concluímos que níveis anormalmente elevados de Ca19-9 não estão necessariamente associados a tumores malignos, e podem conduzir a intervenções médicas desnecessárias e contribuir para o aumento da ansiedade da paciente. Portanto, as características clínicas, os estudos imagiológicos e os marcadores tumorais devem ser interpretados cuidadosamente, e não devem limitar o tipo de conduta cirúrgica.
