Clinical Characteristics of Retroperitoneal Fibrosis Patients at a Tertiary Hospital in Japan.

Retroperitoneal fibrosis (RPF) is a rare cause of hydronephrosis and progressive renal dysfunction with unidentified origin. RPF is categorized into idiopathic RPF with/without immunoglobulin G4 (IgG4)-related disease (IgG4-RD), and secondary RPF. Identifying the underlying cause is challenging and often associated with delayed diagnosis or therapeutic interventions.

Atlantoaxial Subluxation Associated With Chronic Motor Tics.

Head jerking is one of the most common symptoms of motor tics, and because of this, patients are at an increased risk of cervical spine disorders. However, there have been no reports of atlantoaxial subluxation in the English literature. To the best of our knowledge, this is the first case of atlantoaxial subluxation associated with chronic motor tics.

Germline Whole-Gene Deletion of FH Diagnosed from Tumor Profiling.

Hereditary leiomyomatosis and renal cell carcinoma (HL (RCC)) entails cutaneous and uterine leiomyomatosis with aggressive type 2 papillary RCC-like histology. HLRCC is caused by pathogenic variants in the FH gene, which encodes fumarate hydratase (FH). Here, we describe an episode of young-onset RCC caused by a genomic FH deletion that was diagnosed via clinical sequencing.

Incidence and risk factors for postpartum hemorrhage among transvaginal deliveries at a tertiary perinatal medical facility in Japan.

Postpartum hemorrhage (PPH) remains a leading cause of maternal death worldwide, and it is important to understand the relative contributions of different risk factors. We assessed the incidence of these among cases of transvaginal delivery. Between June 2013 and July 2016, a prospective cohort study was conducted at a tertiary perinatal medical facility in Japan.

Case of uterine rupture after multiple intrauterine operations and uterine artery embolization.

Uterine rupture is rare but may result in both maternal and fetal death. The factors involved in such deaths depend on each case, but uterine artery embolization (UAE), the common treatment for hemorrhage, is possibly one factor. UAE may be related to uterine rupture or placenta accreta, but few data exist regarding UAE and uterine rupture.

Primary peritoneal carcinosarcoma arising from the Douglas pouch: A case report.

Primary peritoneal carcinosarcoma is extremely rare and only few cases have been reported in the literature to date. We herein present a case of carcinosarcoma of the Douglas pouch in a 73-year-old Japanese woman. The patient complained of fever and lower abdominal pain, and a large pelvic mass (>10 cm in diameter) was detected, with rectal invasion.

Malignant lymphoma of the uterine cervix presumptively diagnosed by Pap smear: A case report.

Malignant lymphoma of the uterine cervix is exceedingly rare and is difficult to diagnose by cervical cytology. The current study presents a case of malignant lymphoma of the uterine cervix that was presumptively diagnosed by cervical cancer screening in which the patient had no clinical symptoms. The anterior lip of the uterine cervix was occupied by a macroscopic hemorrhagic tumor.

Choosing the uterine preservation surgery for placental polyp determined by blood flow evaluation: A retrospective cohort study.

Background: A placental polyp is an intrauterine polypoid mass or pedunculated mass occurring from residual trophoblastic tissue following abortion, cesarean section or vaginal delivery. Recently uterine preservation surgery represented by transcervical resection (TCR) has been performed for placental polyps. However TCR without intravascular intervention, including uterine artery embolization (UAE) may cause profound bleeding which necessitate emergency laparotomy.

Ethylene Biosynthesis Is Promoted by Very-Long-Chain Fatty Acids during Lysigenous Aerenchyma Formation in Rice Roots.

In rice (Oryza sativa) roots, lysigenous aerenchyma, which is created by programmed cell death and lysis of cortical cells, is constitutively formed under aerobic conditions, and its formation is further induced under oxygen-deficient conditions. Ethylene is involved in the induction of aerenchyma formation. reduced culm number1 (rcn1) is a rice mutant in which the gene encoding the ATP-binding cassette transporter RCN1/OsABCG5 is defective.

RCN1/OsABCG5, an ATP-binding cassette (ABC) transporter, is required for hypodermal suberization of roots in rice (Oryza sativa).

Suberin is a complex polymer composed of aliphatic and phenolic compounds. It is a constituent of apoplastic plant interfaces. In many plant species, including rice (Oryza sativa), the hypodermis in the outer part of roots forms a suberized cell wall (the Casparian strip and/or suberin lamellae), which inhibits the flow of water and ions and protects against pathogens.

Ethylene promotes submergence-induced expression of OsABA8ox1, a gene that encodes ABA 8'-hydroxylase in rice.

A rapid decrease of the plant hormone ABA under submergence is thought to be a prerequisite for the enhanced elongation of submerged shoots of rice (Oryza sativa L.). Here, we report that the level of phaseic acid (PA), an oxidized form of ABA, increased with decreasing ABA level during submergence.
