Severe Renal Hemorrhage in a Pregnant Woman Complicated with Antiphospholipid Syndrome: A Case Report

Antiphospholipid syndrome is a systemic autoimmune disease with thrombotic tendency. Consensus guidelines for pregnancy with antiphospholipid syndrome recommend low-dose aspirin combined with unfractionated or low-molecular-weight heparin because antiphospholipid syndrome causes habitual abortion. We report a 36-year-old pregnant woman diagnosed with antiphospholipid syndrome receiving anticoagulation treatment. The patient developed left abdominal pain and gross hematuria at week 20 of pregnancy. An initial diagnosis of left ureteral calculus was made. Subsequently abdominal-pelvic computed tomography was required for diagnosis because of the appearance of severe contralateral pain. Computed tomography revealed serious renal hemorrhage, and ureteral stent placement and pain control by patient-controlled analgesia were required. After treatment, continuance of pregnancy was possible and vaginal delivery was performed safely. This is the first case report of serious renal hemorrhage in a pregnant woman with antiphospholipid syndrome receiving anticoagulation treatment and is an instructive case for urological and obstetrical practitioners

Therapies for castration-resistant prostate cancer in a new era: The indication of vintage hormonal therapy, chemotherapy and the new medicines

When advanced prostate cancer recurred during hormonal therapy and became the castration-resistant prostate cancer, "vintage hormonal therapy," such as antiandrogen alternating therapy or estrogen-related hormonal therapy, was widely carried out in Japan until 2013. This vintage hormonal therapy controlled the progression of castration-resistant prostate cancer. When castration-resistant prostate cancer relapses during these therapies, chemotherapy using docetaxel has been carried out subsequently. Since new hormonal therapies using abiraterone acetate and enzalutamide, which improve the prognosis of castration-resistant prostate cancer, became available in Japan from 2014, therapeutic options for castration-resistant prostate cancer have increased. Furthermore, the improvement of the further prognosis is promising by using cabazitaxel for docetaxel-resistant castration-resistant prostate cancer and radium-223 for castration-resistant prostate cancer with bone metastasis. An increase in therapeutic options gives rise to many questions, including best timing to use them and the indication. Furthermore, physicians have to consider the treatment for the recurrence after having carried out chemotherapy. We want to argue the difference in hormonal therapy between Japan and Western countries, and problems when carrying out new treatments, and the importance of imaging in the present review article. © 2017 The Japanese Urological Association.Embargo Period 12 month

Differential diagnosis between bacterial infection and neoplastic fever in patients with advanced urological cancer: The role of procalcitonin

It is difficult to determine the cause of high fever in patients with advanced cancer, because they tend to have both neoplastic fever and concomitant bacterial infections with elevated white blood cells and C-reactive protein levels. Procalcitonin has been reported to be a valuable marker for bacterial infections in a wide range of clinical scenarios. However, there have been no studies regarding the usefulness of procalcitonin to differentiate between febrile episodes caused by bacterial infections and neoplastic fever in patients with advanced urological cancer. In the present study, 37 febrile episodes were retrospectively analyzed. Although there were no differences in white blood cell number, C-reactive protein level or body temperature between bacterial infections and non-bacterial infections, procalcitonin levels were significantly higher in the former than the latter. Our findings suggest that measurement of procalcitonin might be valuable to determine the cause of febrile episodes in patients with advanced urological cancer, and can help clinicians to make appropriate decisions for treatment. © 2013 The Japanese Urological Association

Increases in bone turnover marker levels at an early phase after starting zoledronic acid predicts skeletal-related events in patients with prostate cancer with bone metastasis

金沢大学附属病院泌尿器科Study Type - Prognosis (case series) Level of Evidence4 What\u27s known on the subject? and What does the study add? Bone turnover markers such as BAP and 1CTP in patients with SRE or metastatic bone progression were significantly higher at later phase after starting treatment with zoledronic acid compared with those without SRE or progression. However, there are no evident biomarkers predicting SRE or survival at an early phase after starting zoledronic acid treatment. The increase in serum 1CTP and BAP levels at an early phase after starting zoledronic acid treatment predicts short SRE-free survival and overall survival. The measurement of bone turnover markers may be useful for physicians to inform patients of their prognosis and to determine the subsequent treatment plan. OBJECTIVE: To examine whether bone turnover markers could be predictive markers of the probability of newly arising skeletal-related events (SRE) after the start of zoledronic acid treatment in patients with prostate cancer with bone metastasis. PATIENTS AND METHODS: In all, 30 patients with prostate cancer with bone metastasis were treated with zoledronic acid infusion every 4 weeks. Serum C-terminal crosslinking telopeptide of type 1 collagen (1CTP), bone alkaline phosphatase (BAP), and prostate-specific antigen (PSA) levels were measured at the start of zoledronic acid treatment to establish baseline values, and every 4 weeks thereafter. To judge in the early phase whether zoledronic acid is effective in these patients, we retrospectively compared 1CTP, BAP, and PSA levels at 1, 3, and 6 months after starting zoledronic acid treatment with those at baseline. RESULTS: SRE-free survival of patients with increases of 1CTP levels at 1 and 3 months and BAP levels at 3 months were significantly poorer than those of patients with decreases in 1CTP or BAP levels (P = 0.001, P = 0.042, and P = 0.004, respectively). Overall survival of patients with increases of 1CTP levels at 1 and 3 months and of BAP levels at 6 months were significantly poorer than those of patients with decreases of 1CTP or BAP levels (P = 0.013, P = 0.027, and P = 0.035, respectively). CONCLUSION: The measurement of 1CTP and BAP levels at an early phase after starting zoledronic acid treatment may be useful for physicians to inform patients of their prognosis and to determine the subsequent treatment plan. © 2011 THE AUTHORS.

Role of surgical resection in adult urological soft tissue sarcoma: 25-Year experience

金沢大学附属病院泌尿器科The effect of chelating ligands on iron (Fe) uptake and growth of radish (Raphanus sativus L.) was investigated. The ethylenediaminetetraacetic acid (EDTA) increased 55Fe uptake in roots of radish though its subsequent translocation from roots to shoots and leaves did not increase. About 70%-80% of the total 55Fe was distributed in the roots while about 5%-15% and 11%-17% were in shoots and leaves, respectively. The EDTA increased iron uptake into the roots of radish, but not in the above ground parts of the plant. The growth of radish (Raphanus sativus L.) decreased drastically in alkaline condition (pH > 9), even though the concentration of iron was sufficient in the growth medium. The growth of radish was enhanced successfully by the addition of hydroxyiminodisuccinic acid (HIDS) and EDTA. This might be because HIDS and EDTA solubilize iron from its precipitation with hydroxides at higher pH, and increase iron bioavailability. The influence of EDTA and HIDS on radish growth was comparable. Increase of radish growth by ethylenediaminedisuccinic acid (EDDS) and methylglicinediacetic acid (MGDA) was less than those by EDTA and HIDS. Considering the reproducibility of the radish growth (biomass production) at pH 10, HIDS is supposed to be more effective compared to EDTA. © Taylor & Francis Group, LLC
