Clinical Method

Abstract Objective.—To develop breast cancer outcomes data relating pathologic tumor variables at diagnosis with clinical method of detection. Design.—Anatomic pathologists assessed 30 consecutive breast cancers at each institution, resulting in an aggregate database of 4232 breast cancers. Setting.—Hospital-based laboratories from the United States (98%), Canada, Australia, and Belgium. Participants.—One hundred ninety-nine laboratories in the 1999 College of American Pathologists Q-Probes voluntary quality improvement program. Main Outcome Measures.—Pathologic variables indicative of favorable outcomes included percentage of carcinomas detected at the in situ stage, tumors ≤1 cm in diameter, and invasive cancers with lymph nodes negative for metastases. Results.—All outcomes measures, including percent in situ carcinomas (26.9% vs 13.8%), tumor size ≤1 cm (57.8% vs 36.5%), and lymph node–negative status (77.8% vs 64%), were more favorable when tumors were detected by screening mammography (P < .001) compared to all other detection methods. Conclusions.—This study demonstrates an opportunity for pathologists to develop outcomes information of interest to health care organizations, providers, patients, and payers by integrating routine oncologic surgical pathology and clinical breast cancer detection data. Such readily obtained interim outcomes data trended and benchmarked over time can demonstrate the relative clinical efficacy of preventive breast care provided by health care systems long before mortality data are available.

Regulation Compliance

The phenomenon of wastewater sample aging is supposed to be treated with a low temperature autosampler. This work presents two examples of treated wastewater, the quality of which varies with the time of conservation. This evolution may pose some problems with respect to regulation compliance or process control. After the explanation of the mechanisms involved in sample aging, some recommendations are proposed in order to improve the UV off-line measurement of TSS and COD of treated wastewater.

A non-optimised treatment of wastewaters containing organic and biological substances is very often accompanied by an accidental emanation of hydrogen sulphide H2S and therefore leads (i) to an undesirable odour in the vicinity of water treatment plants, and (ii) to a potential hazard for the neighbouring population. Fast, sensitive and reliable monitoring devices are hence of significant importance. Chalcogenide and chalcohalide glasses are new promising membrane materials for detection of heavy metal ions and toxic anions and particularly well adapted for continuous in situ monitoring and industrial process control. In the present paper, we will discuss analytical characteristics of new chalcogenide glass chemical sensors for detection of S2− and dissolved H2S, which allow reliable process control to be carried out at natural pH of wastewaters.
