    Background: The standard range of D-dimer level associated with each type of gynecologic surgery is required to note the occurrence of bleeding or thromboembolism.Methods: Plasma levels of D-dimer of patients who underwent different types of gynecologic surgery were measured on the Day of Preoperative Examination (DPE) and the first postoperative day (POD-1). Patients were classified by surgery type: hysterectomy for benign diseases or cervical intraepithelial neoplasia; hysterectomy for uterine cancer; surgery for ovarian cancer; laparoscopic surgery for a benign adnexal mass; laparotomy for a benign adnexal mass; laparotomic myomectomy; cervical conization; transcervical resection of an intrauterine mass; vaginal surgery for prolapse of a pelvic organ.Results: In each type of gynecologic surgery, plasma levels of D-dimer on POD-1 were higher than those on the DPE. Prophylactic subcutaneous injection of heparin calcium for patients who underwent surgery for endometrial cancer showed no significant difference in the plasma level of D-dimer on the sixth postoperative day (POD-6) and the plasma level of D-dimer on POD-6 was in the same level as those on POD-1.Conclusions: Plasma levels of D-dimer on POD-1 were higher than those on the DPE in each type of gynecologic surgery. The D-dimer level remained high even on POD-6, and not changed by prophylactic subcutaneous injection of heparin calcium.

    Laparoscopic examination of a 77-year-old woman revealed two peritoneal loose bodies connected to fatty appendices on the rectosigmoid colon and resected at the stalks. The peritoneal loose bodies were found to be fat-containing masses on preoperative magnetic resonance imaging, and postoperative pathological examination revealed fat degeneration tissue with or without fibrous outer layers

    Vulvar microinvasive squamous cell carcinoma arising in vulvar intraepithelial neoplasia 3 complicated by genital warts and systemic lupus erythematosus: a case report

    A patient suffering from long-term systemic lupus erythematosus attended with a complaint of recurrent genital warts. Perineal white-colored skin and a peri-anal papillary protrusion adjacent to the genital warts were biopsied and determined to be vulvar intraepithelial neoplasia (VIN) 3 and microinvasive squamous cell carcinoma (SCC), respectively. These lesions were locally excised. Human papillomavirus (HPV)-6 was detected in these lesions, including in the genital warts, while HPV-56 was detected only in the perineal VIN3 and peri-anal microinvasive SCC.

    RBM10 in complete hydatidiform mole: cytoplasmic occurrence of its 50 kDa polypeptide

    Background: RNA-binding motif protein 10 (RBM10), originally identified as S1-1 protein, is a nuclear protein with likely functions in transcription and RNA splicing. The RBM10 gene maps to the X chromosome and, in female cells, is inactivated in one of the two X chromosomes near the boundary with genes escaping inactivation. This study investigated the occurrence of the RBM10 gene product in complete hydatidiform mole, which is composed of cells with paternal diploid chromosomes (46, XX).Methods: Deparaffinized normal chorion or complete hydatidiform mole tissues were hybridized with a fluorescein-conjugated RBM10 gene probe in fluorescent in situ hybridization (FISH) analysis. Immunohistochemistry and immunoelectron microscopy of the tissues were performed using an anti-RBM10 antiserum. Proteins from complete hydatidiform mole tissues and those separated by anti-RBM10-linked affinity chromatography were also examined by western blotting.Results: As expected, the RBM10 gene was detected by FISH as double spots in the nuclei of complete hydatidiform mole cells. Immunohistochemistry revealed a nuclear presence of RBM10 in normal chorion and complete hydatidiform moles, and a notable cytoplasmic presence in complete hydatidiform moles. Western blotting and immunoaffinity chromatography revealed that a 50 kDa protein was predominantly found in the cytosolic fraction of complete hydatidiform moles.Conclusions: A 50 kDa protein with common antigenicity to RBM10 was found in the cytoplasm of complete hydatidiform mole cells, and could represent one of the characteristics of the disease

    Unilateral minimal ovarian cancer with peritoneal implant and an intraepithelial carcinoma in the contralateral fallopian tube

    Get PDF
    Here we present postoperative pathology of an 82-year-old woman who presented with massive ascites, and an implant-like adenocarcinoma on her intrapelvic peritoneum, which revealed a minimal (<5mm) serous adenocarcinoma on her left ovary and an intraepithelial carcinoma on inner surface of her right Fallopian tube.  The left ovarian serous adenocarcinoma may have originated as an intraepithelial carcinoma on contralateral Fallopian tube

    Acute intraabdominal hemorrhage from an aneurysm on uterine artery

    Get PDF
    A 36-year-old woman was underwent emergency laparotomy for acute intraabdominal hemorrhage, but bleeding points were not found. Abdominal pains continued after the laparotomy, and rupture of aneurysm on uterine artery was found in angiography. An transcatheter arterial embolization was done for the uterine artery, and the aneurysm was found to disappear in 4-day-after the angiography. Rupture of an aneurysm on uterine artery should be considered for the causes of acute intraabdominal hemorrhage

    Increased oxidative stress precedes the onset of high-fat diet-induced insulin resistance and obesity

    金沢大学医薬保健研究域医学系Insulin resistance is a key pathophysiological feature of metabolic syndrome. However, the initial events triggering the development of insulin resistance and its causal relations with dysregulation of glucose and fatty acids metabolism remain unclear. We investigated biological pathways that have the potential to induce insulin resistance in mice fed a high-fat diet (HFD). We demonstrate that the pathways for reactive oxygen species (ROS) production and oxidative stress are coordinately up-regulated in both the liver and adipose tissue of mice fed an HFD before the onset of insulin resistance through discrete mechanism. In the liver, an HFD up-regulated genes involved in sterol regulatory element binding protein 1c-related fatty acid synthesis and peroxisome proliferator-activated receptor α-related fatty acid oxidation. In the adipose tissue, however, the HFD down-regulated genes involved in fatty acid synthesis and up-regulated nicotinamide adenine dinucleotide phosphate (NADPH) oxidase complex. Furthermore, increased ROS production preceded the elevation of tumor necrosis factor-α and free fatty acids in the plasma and liver. The ROS may be an initial key event triggering HFD-induced insulin resistance. © 2008 Elsevier Inc. All rights reserved

    Heparin cofactor II reduces albuminuria

    Aims/Introduction: Thrombin exerts various pathophysiological functions by activating protease-activated receptors (PARs). Recent data have shown that PARs influence the development of glomerular diseases including diabetic kidney disease (DKD) by regulating inflammation. Heparin cofactor II (HCII) specifically inactivates thrombin; thus, we hypothesized that low plasma HCII activity correlates with DKD development, as represented by albuminuria. Materials and Methods: Plasma HCII activity and spot urine biomarkers, including albumin and liver-type fatty acid-binding protein (L-FABP), were determined as the urine albumin-to-creatinine ratio (uACR) and the urine L-FABP-to-creatinine ratio (uL-FABPCR) in 310 Japanese patients with diabetes mellitus (176 males and 134 females). The relationships between plasma HCII activities and those DKD urine biomarkers were statistically evaluated. In addition, the relationship between plasma HCII activities and annual uACR changes was statistically evaluated for 201/310 patients (115 males and 86 females). Results: The mean plasma HCII activity of all participants was 93.8 ± 17.7%. Multivariate-regression analysis including confounding factors showed that plasma HCII activity independently contributed to the suppression of the uACR and log-transformed uACR values (P = 0.036 and P = 0.006, respectively) but not uL-FABPCR (P = 0.541). In addition, plasma HCII activity significantly and inversely correlated with annual uACR and log-transformed uACR increments after adjusting for confounding factors (P = 0.001 and P = 0.014, respectively). Conclusions: The plasma HCII activity was inversely and specifically associated with glomerular injury in patients with diabetes. The results suggest that HCII can serve as a novel predictive factor for early-stage DKD development, as represented by albuminuria
