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...

PROBLEM: Resistance to methotrexate is a leading clinical problem in gestational trophoblastic neoplasia (GTN), but there are limited laboratory models for this condition. METHOD OF STUDY: We created isogenic trophoblastic cell lines resistant to methotrexate and compared these to the parent cell lines using gene expression microarrays and qRT-PCR followed by mechanistic studies using recombinant cytokines, pathway inhibitors, and patient sera. RESULTS: Gene expression microarrays and focused analysis by qRT-PCR revealed methotrexate led to type I interferon upregulation, in particular interferon alpha 2 (IFNA2), and methotrexate resistance was associated with chronic low level increases in type I interferon expression...

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...

The sphincter of Oddi (SO) is a smooth muscle valve regulating the flow of biliary and pancreatic secretions into the duodenum, initially described in 1887 by the Italian anatomist, Ruggero Oddi. SO dysfunction (SOD) is a broad term referring to numerous biliary, pancreatic, and hepatic disorders resulting from spasms, strictures, and relaxation of this valve at inappropriate times. This review brings attention to various factors that may increase the risk of SOD, including but not limited to: cholecystectomy, opiates, and alcohol...

BACKGROUND: Symmetric (SDMA) and asymmetric (ADMA) dimethylarginines have emerged as novel biomarkers of cardiovascular disease (CVD) in several disease settings associated with atherosclerosis. Rheumatoid arthritis (RA) is a chronic systemic inflammatory disease characterized by high CVD mortality and morbidity. ADMA and SDMA levels are abnormal in RA patients, but their correlation with assessments of endothelial function and structure remains unknown. We aimed to investigate whether SDMA and ADMA are associated with carotid intima media thickness (cIMT) and arterial stiffness as well as non-invasive assessments of in vivo micro- and macrovascular endothelial function in RA patients with high systemic inflammatory load...

OBJECTIVE: Women older than 40 years develop gestational trophoblastic neoplasia (GTN) after a hydatidiform mole (HM) more often than do younger women. Therefore, in elderly women, primary hysterectomy has been advocated as first-line treatment. The aim of the present study was to evaluate whether hysterectomy could reduce the incidence of GTN after a diagnosis of HM. METHODS: Seventy-six of 442 patients referred to our unit for an HM between 1994 and 2015 were older than 40 years old...

INTRODUCTION: Chronic anal fissure is associated with significant morbidity and reduction in quality of life mostly in young healthy adults. Glyceryl Trinitrate, a most commonly used agent for treatment, is associated with incidence of headache causing discontinuation of treatment. There is belief that endoanal application instead of perianal is associated with lower incidence of headache. This study is to compare the incidence and severity of headache in between perianal and endoanal application of GTN ointment...

OBJECTIVES: In patients with systemic sclerosis (SSc), fingertip digital ulcers (DUs) are believed to be ischaemic, and extensor surface DUs a result of mechanical factors/microtrauma. Our aim was to assess blood flow response to topical glyceryl trinitrate (GTN) compared to placebo in SSc DUs, looking for differences in pathophysiology between fingertip and extensor lesions. METHOD: This was a double-blind, randomised, crossover, placebo-controlled study. Sixteen (6 fingertip, 10 extensor) DUs were each studied twice (one day apart): once with GTN and once with placebo ointment...

OBJECTIVE: Decreased brain-derived neurotrophic factor (BDNF) level has been reported in the hippocampus of hypertensive rats. The present study explored whether brain neurons and/or endothelial cells are targeted by hypertension with respect to BDNF expression and the potential of physical exercise to cope with hypertension. METHODS: Physical exercise was induced in spontaneously hypertensive rats (SHR) and Wistar Kyoto (WKY) rats. The hippocampus of sedentary and exercised rats (n = 6 for each group) were used for western blots to assess proBDNF, mature BDNF (mBDNF), tropomyosin-related kinase B (TrkB), P-TrkB (TrkB phosphorylated at tyrosine 816), synaptophysin, endothelial nitric oxide synthase (eNOS) and eNOS phosphorylated at serine 1177 protein levels...

Choriocarcinoma is one of the gestational trophoblastic neoplasia (GTN) that originate in the chorionic villi and the extravillous trophoblast. Long non-coding RNA (lncRNA) is a type of non-protein-coding RNAs that have recently been implicated in human tumoriogenesis. The present study investigated the role of an lncRNA LINC00261 in the cell proliferation, metastasis and apoptosis in choriocarcinoma cell lines. The transcription level of lncRNA LINC00261 was significantly lower in choriocarcinoma tissues and in choriocrcinoma cell lines...

Choriocarcinoma is a malignant gestational trophoblastic neoplasia (GTN) and one of the curable types of gynecological cancer. However, 10% of choriocarcinoma patients have a poor prognosis, particularly when they have metastasis, apart from pulmonary metastasis, or do not go into remission by the second chemotherapeutic regimen. We herein present the case of a 36-year-old patient who had choriocarcinoma with metastases to the lungs, liver and kidneys. The 5th and 6th regimens with cisplatin for choriocarcinoma failed and the patient developed brain metastases...

Gestational trophoblastic disease (GTD) is a group of conditions that originate from the abnormal proliferation of trophoblastic cells. GTDs encompass hydatidiform moles (HMs) and gestational trophoblastic neoplasia (GTN). GTNs are a group of malignant diseases that require chemotherapy, or more aggressive treatment. There is a requirement for more tumor markers to predict the development of GTN from HMs. The current study evaluated the expression of maspin and tumor protein p53 (p53) in GTD, and their role in predicting the development of GTN...
