SDF-1/CXCR4 signaling axis determines the proliferative potential and site-specific cancer metastasis. Recent studies suggest involvement of the axis and steroidal hormone in ovarian cancer metastasis. Here we hypothesize that mifepristone (RU486), a well-known progesterone-based abortifacient, might interfere this axis and inhibit ovarian cancer metastasis. Mifepristone at concentrations < IC50 inhibited expression of CXCR4 on cell surface of ovarian cancer SKOV-3 and IGROV-1, and reduced expression of the intracellular CXCR4 protein and its related mRNA activated by SDF-1...

A standard strategy against ascites, a common symptom observed in cirrhotic and cancer patients, includes restriction of sodium intake and use of a diuretic. Paracentesis is a widely applied method against refractory ascites that do not react to such treatment. However, emerging fatigue and hemodynamic instability are possibly attributable to a loss of protein included in ascites. Cell-free and Concentrated Ascites Reinfusion Therapy (CART) is also applied against refractory ascites. CART comprises three processes...

Ascites is a major complication of cirrhosis. There are several evidence-based articles and guidelines for the management of adults, but few data have been published in relation to children. In the case of a pediatric patient with cirrhotic ascites (PPCA), the following questions are raised: How are the clinical assessment and ancillary tests performed? When is ascites considered refractory? How is it treated? Should fresh plasma and platelets be infused before abdominal paracentesis to prevent bleeding? What are the hospitalization criteria? What are the indicated treatments? What complications can patients develop? When and how should hyponatremia be treated? What are the diagnostic criteria for spontaneous bacterial peritonitis? How is it treated? What is hepatorenal syndrome? How is it treated? When should albumin be infused? When should fluid intake be restricted? The recommendations made here are based on pathophysiology and suggest the preferred approach to diagnostic and therapeutic aspects, and preventive care...

To date, the lack of chemo-naive cell models limited exploratory studies to define novel therapies for Burkitt lymphoma (BL). To obtain a useful tool for biological and translational studies for this tumor, we established the RALE051 cell line from the malignant ascitic fluid cells of a patient at initial diagnosis, not previously exposed to any treatment. The cell line was characterized by karyotyping, fluorescence in situ hybridization (FISH), single nucleotide polymorphism (SNP) array, immunohistochemistry, and RNA-Seq, revealing the persistence of biological and molecular features observed in the primary ascitic fluid, such as the cell morphology and immunophenotype, the occurrence of a t(8;22) translocation deregulating MYC, knock-out ID3 mutations in a compound homozygous state, and a mutated TP53...

Circulating cell-free DNA (ccfDNA) can be found in various body fluids, i.e., blood (serum and plasma), urine, pleural effusions, and ascites. While ccfDNA predominantly originates from physiological processes, a fraction might be related to pathological events, e.g., cancer. Aberrant DNA methylation, which is considered a hallmark of cancer, can be assessed accurately in ccfDNA. Consequently, DNA methylation testing in body fluids represents a powerful diagnostic tool in the clinical management of malignant diseases...

The exact role of malignant ascites in the development of intraperitoneal ovarian cancer metastases remains unclear. In this report we sought to establish if ascites can determine the efficiency of transmesothelial invasion of ovarian cancer cells, and, if so, whether the fluid generated by highly aggressive serous and undifferentiated tumors will promote the invasion more effectively than ascites from less aggressive clear cell and endometrioid cancers. The study showed that the invasion of ovarian cancer cells (SKOV-3 and primary cancer cells) across monolayered peritoneal mesothelial cells was elevated upon mesothelial cell exposure to fluid produced by serous and undifferentiated cancers, as compared with cells subjected to ascites from clear cell and endometrioid tumors...

A 36-year-old woman with essential thrombocythemia (ET) was admitted to our hospital for acute lower abdominal pain. Given no family history of bleeding disorder, she was diagnosed with acquired von Willebrand syndrome. Despite having a medical history of venous thrombosis, she had never been treated for ET because of her preferences. On admission, CT scan revealed massive hemorrhage in the ascending colon with the leakage of a contrast agent. Furthermore, a delayed enhancement of fluid collection in the Douglas fossa followingcontrast CT indicated bloody ascites...

Idiopathic nephrotic syndrome (INS) is a kidney disease characterized by massive proteinuria. Protein loss leads to decreased oncotic pressure shifting the fluids into the interstitial space causing edema, complications such as infections and thromboembolism occur. We report a 7-year-old, diagnosed with NS presenting with a relapse. He developed ascites and scrotal edema followed by severe scrotal pain and redness, progressing rapidly to ecchymosis in the inguinal areas not in continuity with the scrotum. Ultrasound with color Doppler was inconclusive, scrotal exploration was done along with skin incision in the inguinal areas and scrotum, which appeared to relieve the condition rapidly...

Bacterial translocation (BT) is an important mechanism in the development of infection in liver cirrhosis. The migration and colonization of bacteria and/or bacterial products from the bowel to mesenteric lymph nodes is a controlled process in healthy persons. Increased intestinal permeability, bacterial overgrowth and defect of gut-associated lymphatic tissue promote impaired BT in cirrhotics. We reviewed the reports on markers used for the evaluation of BT published between 1987 and 2016. We focused on the clinical consequences of BT in cirrhosis, as indicated by the values of the BT markers...

Percutaneous image-guided ablation is performed throughout many areas of the body for various pathologies including hepatic malignancies. Heat and cold-based ablative technologies are effective and well-tolerated with an acceptable safety profile. However, ablative therapies may be technically more challenging and cause collateral thermal injury if the targeted lesion is adjacent to critical organs. Previously, techniques including artificial ascites and pneumoperitoneum have been utilized to displace or insulate critical structures from the ablation zone...
