A case of third trimester uterine prolapse resulting in vaginal delivery by placement of an intravaginal balloon.

Pregnancies complicated by uterine prolapse are rare, occurring in 1 in 10 000 to 15 000 deliveries. We report a case of uterine prolapse at 36 weeks of gestation that resulted in vaginal delivery by placement of a colpeurynter (intravaginal balloon). The patient was a 33-year-old pregnant woman with a history of uterine prolapse during her previous pregnancy.

Betamethasone use and risk factors for pulmonary edema during the perinatal period: a single-center retrospective cohort study in Japan.

Background: A few studies have reported that maternal administration of antenatal corticosteroids increased the risk of pulmonary edema (PE). However, despite the increasing usage rate of betamethasone as antenatal corticosteroid, maternal administration of betamethasone as a risk factor for PE has not been well studied. This study aimed to evaluate how maternal backgrounds and complications, tocolytic agents, and betamethasone affect the incidence of PE during the perinatal period and determine the risk factor for PE.

Isolated levocardia: prenatal diagnosis and management.

Isolated levocardia (IL) is a rare condition of situs anomaly in which there is a normal left-sided heart (levocardia) with dextro position of the abdominal viscera. IL has been reported in children and adults with complex cardiac defects, whereas there are only few published reports regarding the prenatal diagnosis of IL. We report two prenatal cases of IL diagnosed by ultrasonography and magnetic resonance imaging (MRI).

Classification using hierarchical clustering of tumor-infiltrating immune cells identifies poor prognostic ovarian cancers with high levels of COX expression.

Local immune status is influenced by the tumor microenvironment. This study aims to characterize the local immune/microenvironment status by examining tumor-infiltrating immune cells, as well as cyclooxygenase (COX) expression in tumor cells, and to analyze the relationship with the prognosis of ovarian cancers. Using immunohistochemical staining of 70 ovarian cancer specimens, the numbers of CD8+, CD57+, and CD1a+ cells infiltrating intraepithelial or stromal spaces were counted (six parameters).

Malignant transformation of mature cystic teratoma of the ovary including three cases occurring during follow-up period.

The aim of this study was to seek for factors which lead to the early diagnosis of malignant transformation from mature cystic teratoma. Fourteen patients with malignant transformation from mature cystic teratoma of the ovary were analyzed retrospectively for precise clinicopathology and prognosis. The results demonstrated that although all the patients with stage Ia disease were disease-free, only 2 out of 7 patients were stage Ic to IV and disease-free in the follow-up period.

Intractable recurrent cervical cancer with pelvic bone involvement successfully treated with external hemipelvectomy.

The indication of external hemipelvectomy for lateral recurrent cervical cancer involving the pelvic bone is controversial. We report the second longest surviving patient of recurrent cervical cancer successfully treated by external hemipelvectomy. A 38-year-old woman who had undergone conization for stage Ia1 cervical cancer six years earlier had severe right inguinal pain.

Immunostimulatory effect of Fms-like tyrosine kinase 3 ligand on peripheral monocyte-derived dendritic cells and natural killer cells: utilization for ovarian cancer treatment.

Systemic administration of Fms-like tyrosine kinase 3 ligand (FLT3L) has been considered to be a major route of delivery for tumor immunotherapy because expression of its receptor, FLT3, was detected predominantly in hematopoetic progenitor cells. However, several studies indicate that FLT3L locally overexpressed in tumor or dendritic cells (DCs) also shows an anti-tumor effect. In the current study, we found that FLT3 expression is not present in monocytes but is instead induced in DCs through the differentiation process resulting from stimulation by GM-CSF and IL-4.

Neuropilin-1 promotes unlimited growth of ovarian cancer by evading contact inhibition.

Objective: Neuropilin-1 (NRP-1) is a receptor for both semaphorin and vascular endothelial growth factor and is up-regulated in a variety of human cancers. While there are some reports of NRP-1 expression in ovarian neoplasm, those results differ in pattern of its expression and its role in ovarian cancer is still unclear. We sought to investigate the expression pattern and role of NRP-1 in ovarian cancer.

Oncogenic property of acrogranin in human uterine leiomyosarcoma: direct evidence of genetic contribution in in vivo tumorigenesis.

To identify potential oncogenes that contribute to the development of uterine leiomyosarcoma, we conducted a cDNA microarray analysis between normal uterine smooth muscle and uterine leiomyosarcoma. We found that acrogranin (also named PCDGF or progranulin) is overexpressed in uterine leiomyosarcoma. With immunohistochemical staining of 12 leiomyosarcoma cases, we verified acrogranin expression in tumor cells.

In vivo anti-tumor effect of dual release of cisplatin and adriamycin from biodegradable gelatin hydrogel.

The objective of this paper is to investigate the in vivo anti-tumor effect by dual release of cisplatin (CDDP) and adriamycin (ADM) from a biodegradable hydrogel. Hydrogels with different water contents were prepared through the chemical crosslinking of gelatin by various concentrations of glutaraldehyde. Aqueous solution of CDDP, ADM or their mixture (CDDP+ADM) was impregnated into the freeze-dried hydrogel, followed by air-drying to obtain the dried hydrogel incorporating the corresponding drug.

Increased expression of calcium-binding protein S100 in human uterine smooth muscle tumours.

S100 proteins belong to the EF-hand Ca(2+ )-binding protein family and regulate a variety of cellular processes via interaction with different target proteins. Several diseases, including cancer and melanoma, are related to the abnormal expression of S100 proteins, which are expressed in cell- and tissue-specific manners. We investigated the expression of S100 family members in human uterine smooth muscle tumours.

PEP-19 overexpression in human uterine leiomyoma.

Although uterine leiomyomas represent one of the most common neoplasms in adult women, their pathogenesis remains poorly understood. A cDNA microarray analysis was performed to search for candidate genes expressed to a greater degree in leiomyoma compared with matched myometrium. A total of 15 candidate genes was obtained; neuron-specific protein PEP-19 (Purkinje cell protein 4; PCP 4) exhibited a striking difference in expression between leiomyoma and myometrium.

Expression of cold-inducible RNA-binding protein in the normal endometrium, endometrial hyperplasia, and endometrial carcinoma.

Cold-inducible RNA-binding protein (CIRP), an 18-kD protein in the mouse and human, is induced by lowering the temperature of cultured cells. CIRP is possibly a cell cycle regulator because its overexpression results in prolongation of G1 phase in vitro. We investigated the immunohistochemical expression of CIRP in 39 endometrial carcinomas, 12 endometrial hyperplasias, and 27 normal endometria using polyclonal antibody against CIRP and confirmed by Western blot analysis.

Tranilast inhibits the proliferation of uterine leiomyoma cells in vitro through G1 arrest associated with the induction of p21(waf1) and p53.

Uterine leiomyoma is a mesenchymal tumor composed of smooth muscle cells with fibrous tissues and many mast cells. Tranilast is known to suppress fibrosis or to work as a mast cell stabilizer and is reported to inhibit proliferation of vascular smooth muscle cells. In this study, we examined the effects of tranilast on cultured human leiomyoma cells in vitro to evaluate whether this agent has the potential to inhibit the growth of uterine leiomyomas.

Secreted frizzled related protein 1 is overexpressed in uterine leiomyomas, associated with a high estrogenic environment and unrelated to proliferative activity.

Secreted frizzled related protein 1 (sFRP1) is a modulator of Wnt signaling. Recently, aberrations of Wnt signaling were reported to be involved in the pathology of various human neoplasms. We investigated the expression and function of sFRP1 in uterine leiomyomas.
