Disappearance and prevalence of extended-spectrum β-lactamase-producing Escherichia coli and other coliforms in the wastewater treatment process.

Antibiotic-resistant bacteria (ARBs) can now be detected not only in clinical institutions but also in wastewater treatment plants (WWTPs), extending the range of emergence to residential areas. In this study, we investigated the change of antibiotic-resistant Escherichia coli (E. coli) and other coliforms in each treatment process at WWTPs.

Growth and Decay of Fecal Indicator Bacteria and Changes in the Coliform Composition on the Top Surface Sand of Coastal Beaches during the Rainy Season.

High counts of bacteria are present in beach sand, and human health threats attributable to contact with sand have been reported. In this study, we investigated fecal indicator bacteria in the top surface sand of coastal beaches. Monitoring investigations were performed during a monsoon when rainfall occurs randomly, and the composition of the coliforms was analyzed.

Clinical efficacy and value of redistributed subclavian arterial infusion chemotherapy for locally advanced breast cancer.

Purpose: The aim of this study was to evaluate the efficacy and safety of redistributed subclavian arterial infusion chemotherapy (RESAIC). We have focused on the local response, quality of life (QOL), and complications. We have also investigated factors that influence the local response of RESAIC.

Radiologic-pathological correlation of punctate hyperechoic foci by ultrasound in stereotactic vacuum-assisted breast biopsy samples.

Purpose: To correlate punctate hyperechoic foci (PHF) on ultrasound (US) with microcalcifications detected by mammography (MMG) and at histopathology.

Materials And Methods: Forty-eight subjects who underwent stereotactic vacuum-assisted breast biopsy (SVABB) for evaluation of breast microcalcifications between April and December 2008 were evaluated for 191 lesions obtained after SVABB. The concordance between PHF on US with microcalcifications detected on MMG and histopathology was therefore evaluated for 191 lesions.

Clinical application of a new indwelling catheter with a side-hole and spirally arranged shape-memory alloy for hepatic arterial infusion chemotherapy.

A new indwelling catheter, G-spiral (GSP), was developed for hepatic arterial infusion chemotherapy (HAIC) by way of an implanted catheter-port system (CPS). Here we evaluated its physical properties and the outcomes of its clinical use. The GSP vessel-fixing power and its ability to follow a guidewire were determined with a vascular in vitro model, and Student t test was used to determine statistical significance (P < 0.

A case of a fibroadenoma coexisting with an invasive lobular carcinoma in the breast.

A case of a fibroadenoma coexisting with an invasive lobular carcinoma of the breast in a 60-year-old female is presented, and its pathological features are correlated with high-resolution magnetic resonance imaging (HR-MRI) and other imaging findings. The patient presented with the chief complaint of having a palpable mass in her right breast for 3 months. Mammography revealed a lobular mass with a micro-lobulated margin, which suggested a malignant nature; however, it included coarse calcifications.

Development of a new subclavian arterial infusion chemotherapy method for locally or recurrent advanced breast cancer using an implanted catheter-port system after redistribution of arterial tumor supply.

Locally or recurrent advanced breast cancers can receive arterial blood supply from various arteries, such as the internal thoracic artery (ITA), the lateral thoracic artery, and the other small arterial branches originating from the subclavian artery. Failure to catheterize and subsequent formation of collateral arterial blood supply from various arteries are some of the reasons why the response to conventional selective transarterial infusion chemotherapy is limited and variable. To overcome this problem, we developed a new subclavian arterial infusion chemotherapy method using an implanted catheter-port system after redistribution of arterial tumor blood supply by embolizing the ITA.

Central venous access port-related complications in outpatient chemotherapy for colorectal cancer.

Background: The current standard chemotherapy for advanced or metastatic colorectal cancer in Japan is FOLFOX or FOLFIRI therapy. Although both therapies include continuous infusion of 5-fluorouracil (5-FU), outpatient home chemotherapy is possible by placing a central venous access port (CV-port) and using a portable disposable pump. The port system has been placed more frequently since the approval of FOLFOX.

Hepatic arterial infusion chemotherapy through a port-catheter system as preoperative initial therapy in patients with advanced liver dysfunction due to synchronous and unresectable liver metastases from colorectal cancer.

Purpose: We retrospectively evaluated the safety and efficacy of preoperative initial hepatic arterial infusion chemotherapy (HAIC) through a port-catheter system in patients with liver dysfunction due to synchronous and unresectable liver metastases. The aim of HAIC was to improve patients' clinical condition for later surgical removal of primary colorectal cancer.

Methods: Port-catheter systems were placed radiologically in 21 patients (mean age 58.

Chest wall dissemination of nocardiosis after percutaneous transthoracic needle biopsy.

We described a case of chest wall dissemination after percutaneous transthoracic needle biopsy. A 65-year-old man had a lung nodule which was suspected to be lung carcinoma. He underwent percutaneous transthoracic needle biopsy using an 18G semiautomated biopsy needle and pathologic diagnosis showed organizing pneumonia.

Bilateral pneumothorax after unilateral transthoracic puncture.

Pneumothorax is a common complication following transthoracic interventional procedures. Most often, this occurs unilaterally on the side of the intervention. Bilateral pneumothorax following unilateral puncture is rare, but may mandate emergent chest tube insertion.

Pseudo-occlusion of the hepatic artery during hepatic arterial infusion chemotherapy.

Hepatic arterial occlusion (HAO) is frequently encountered in patients receiving hepatic arterial infusion chemotherapy (HAIC) via an implanted port-catheter system. Usually, HAO precludes continuation of HAIC, and treatment for liver metastases is changed to systemic chemotherapy. However, two cases were encountered in which, even though HAO was diagnosed by arteriography via the port, the hepatic artery was actually patent.

Radiologic removal and replacement of port-catheter systems for hepatic arterial infusion chemotherapy.

Objective: The purpose of our study was to retrospectively evaluate the safety and efficacy of radiologic removal and replacement of port-catheter systems.

Materials And Methods: Between January 1999 and December 2004, 532 patients with unresectable advanced liver cancer underwent radiologic placement of port-catheter systems at our institution. Of these, 18 patients (nine men and nine women; age range, 32-83 years; mean age, 53.

[Retrospective analysis of tegafur/uracil (UFT) plus oral leucovorin (LV) regimen in patients with advanced colorectal cancer].

The clinical efficacy and safety of tegafur/uracil (UFT) plus oral Leucovorin (LV) regimen for advanced or metastatic colorectal cancer were studied retrospectively. From September 2003 to March 2005, 82 patients were treated with UFT (300 mg/m(2)/day)/LV (75 mg/day) at our institute. The objective overall response rate was 14.
