Placental mesenchymal dysplasia (PMD) is an uncommon vascular anomaly of the placenta characterized by placentomegaly with multicystic placental lesion on ultrasonography and mesenchymal stem villous hyperplasia on histopathology. Placental mesenchymal dysplasia should be considered in the differential diagnosis of cases of multicystic placental lesion such as molar pregnancy, chorioangioma, subchorionic hematoma, and spontaneous abortion with hydropic placental changes. However, lack of high-velocity signals inside the lesion and a normal karyotype favor a diagnosis of PMD...

OBJECTIVE: The aim of this study was to comparatively study a novel model and existing models of predicting postmolar gestational trophoblastic neoplasia (GTN). METHODS: Two hundred twenty-two patients with complete hydatidiform moles were enrolled retrospectively. A natural regression was noted in 195 patients (spontaneous regression group), whereas the remaining 27 patients entered postmolar GTN (postmolar GTN group). The upper limits of the 95% confidence interval of human chorionic gonadotropin (hCG) values and hCG regression rates were calculated aggregately from the spontaneous regression group...

Gestational trophoblastic neoplasia (GTN) is a spectrum of diseases including partial and complete hydatidiform moles, placental site trophoblastic tumor, and choriocarcinoma. One of the most important considerations is recognition of the possibility of GTN after molar pregnancy or even normal pregnancy. It is common practice to use chest x-ray for the detection of pulmonary metastasis. Computed tomography imaging of the lungs is ordered if lung lesions are noted on chest x-rays. However, understanding the limitations of chest x-rays is important for detecting smaller pulmonary lesions...

The Gestational Trophoblastic Disease includes an interrelated group of diseases originating from placental tissue, with distinct behaviors concerning local invasion and metastasis. The high sensitivity of the serial dosages of human chorionic gonadotrophin, combined with advances in chemotherapy treatment, have made gestational trophoblastic neoplasia curable, most often through chemotherapy. However, surgery remains of major importance in the management of patients with gestational trophoblastic disease, improving their prognosis...

In assisted reproduction, embryos derived from monopronucleated (1PN) zygotes are considered abnormal and unsuitable for clinical use. Outcomes of 1PN-derived embryos designated for preimplantation genetic screening (PGS) were analysed. These embryos, especially from intracytoplasmic sperm injection (ICSI), were found to have a low developmental potential; 1PN and 2PN day 5 blastocyst development for IVF was 14.8% versus 36.4% (P < 0.0001), and for ICSI, 6.6% versus 34.0% (P < 0.0001), respectively. With the use of comparative genomic hybridization or next-generation sequencing, PGS was successfully carried out for 74 IVF and 32 ICSI 1PN-derived blastocysts, revealing adjusted abnormality rates of 39...

BACKGROUND: Invasive mole is responsible for most cases of localized gestational trophoblastic neoplasia. Gestational trophoblastic disease describes a number of gynecologic tumors that originate in trophoblastic layer including hydatidiform mole (complete or partial), invasive mole, choriocarcinoma, placental site trophoblastic tumor and epitheloid trophoblastic tumor. Invasive mole may arise from any pregnancy event although in most cases is diagnosed after molar pregnancy. Overall cure rate in low risk patients is nearly 100% and in high-risk patient 90%...

BACKGROUND/AIMS: We updated human chorionic gonadotropin (hCG) regression curves created in the eighties after evacuation of complete and partial molar (CM and PM, respectively) pregnancies using modern hCG assays. We created similar curves for patients in need of chemotherapy (gestational trophoblastic neoplasia [GTN]). METHODS: A total of 126 patients who were diagnosed with gestational trophoblastic disease from 1990 to 2014 were included. We compared curves from 2 groups, CM and PM, with historical ones...

Gestational trophoblastic disease (GTD) is a spectrum of both benign and malignant gestational tumors, including hydatidiform mole (complete and partial), invasive mole, choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. The latter four entities are referred to as gestational trophoblastic neoplasia (GTN). These conditions are aggressive with a propensity to widely metastasize. GTN can result in significant morbidity and mortality if left untreated. Early diagnosis of GTD is essential for prompt and successful management while preserving fertility...

Tooth eruption is defined as the movement of a tooth from its site of development within the alveolar process to its functional position in the oral cavity. The process of tooth eruption can be divided into different phases: pre-eruptive bone stage, alveolar bone stage, mucosal stage, preocclusal stage, occlusal stage and maturation stage. Any disturbance in these phases can lead to eruptive anomalies. The incidence of unerupted teeth is usually higher among permanent teeth than among deciduous ones. Of the primary teeth reported as unerupted, second deciduous molars are the teeth most frequently involved, followed by primary central incisors...

Introduction. Intra-amniotic infection (IAI) is a major cause of preterm labor and adverse neonatal outcome. We evaluated amniotic fluid (AF) proteolytic cascade forming biomarkers in relation to microbial invasion of the amniotic cavity (MIAC) and IAI in preterm pregnancies with intact membranes. Material and Methods. Amniocentesis was made to 73 women with singleton pregnancies; 27 with suspected IAI; and 46 controls. AF biomarkers were divided into three cascades: Cascade 1: matrix metalloproteinase-8 (MMP-8), MMP-9, myeloperoxidase (MPO), and interleukin-6; Cascade 2: neutrophil elastase (HNE), elafin, and MMP-9; Cascade 3: MMP-2, tissue inhibitor of matrix metalloproteinases-1 (TIMP-1), MMP-8/TIMP-1 molar ratio, and C-reactive protein (CRP)...

We present our experience of using the HDlive silhouette inversion mode to assess complete hydatidiform mole early in pregnancy. The HDlive silhouette inversion mode clearly depicted the number, size, and spatial position of molar vesicles, compared with conventional two-dimensional sonography or the HDlive inversion mode. Moreover, spatial relationships among molar vesicles, intrauterine anechoic fluid collection, and the uterine wall enabled the clear localization of the lesion. This technique provides new insights, and has the potential to supplement conventional two-dimensional sonography in the diagnosis of complete hydatidiform mole...

Lactoferrin and lysozyme are 2 glycoproteins with great antimicrobial activity, being part of the nonspecific defensive system of human milk, though their use in commercial products is difficult because human milk is a limited source. Therefore, many investigations have been carried out to produce those proteins in biological systems, such as bacteria, yeasts, or plants. Mammals seem to be more suitable as expression systems for human proteins, however, especially for those that are glycosylated. In the present study, we developed a bicistronic commercial vector containing a goat β-casein promoter and an internal ribosome entry site fragment between the human lactoferrin and human lysozyme genes to allow the introduction of both genes into bovine adult fibroblasts in a single transfection...

Joubert syndrome (JS) is an autosomal recessive disorder, which is characterized by hypotonia, ataxia, psychomotor delay, and variable occurrences of oculomotor apraxia and neonatal breathing abnormalities. JS is clinically and genetically heterogeneous. The present study investigated a typical JS family. The 'molar tooth sign' was observed in the proband through magnetic resonance imaging. Other symptoms of JS include cerebellar vermis hypoplasia/dysplasia, oculomotor apraxia and intellectual disability. High‑throughput sequencing revealed that JS was caused by coiled‑coil and C2 domain containing 2A (CC2D2A) compound heterozygous mutations...
