Context.--The Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations for proficiency testing (PT) include prohibitions against intentional PT sample referral or result communication, and specify sanctions against laboratories that violate these regulations. There has been little published analysis of sanctions against clinical laboratories because of PT violations.

Context.--Anatomic pathology diagnosis is often based on morphologic features. In recent years, an appropriate increased attention to patient safety has led to an emphasis on improving maintenance of patient identity. Decreasing or eliminating cross-contamination from one specimen to another is an example of a patient identity issue for which process ...

* Context.--Epithelioid hemangioendothelioma (EHE) is a rare vascular neoplasm of intermediate malignancy. Epithelioid hemangioendothelioma often presents a difficult diagnostic problem, especially in bone, because the epithelioid morphology and radiographic features raise the possibility of metastatic carcinoma. The current trend of small biopsies obtained with computed tomography-guided techniques exacerbates the problem. ...

* Context.--Correction factors have been proposed for estimating true potassium concentrations in blood samples with evidence of in vitro hemolysis.
Seethala, Raja - - 2009
* Context.--Recently described variants of epithelial-myoepithelial carcinoma have not been well characterized but raise a distinct set of differential diagnostic considerations than the classic type.

* Context.--A variety of document control practices are required of clinical laboratories by US regulation, laboratory accreditors, and standard-setting organizations.
Yee, Kwang - - 2009
* The health care system is extremely complex and it is currently undergoing a massive transformation with rapid advances in technology. Pathology services have been leading the technology adaptation process and will continue to evolve rapidly with the introduction of "omics" technology. Future pathology informatics systems (PIS) will need to ...
Georgiou, Andrew - - 2009
* The introduction of computerized provider order entry (CPOE) systems is associated with major changes in work processes. Implementation strategies need to consider how the technology will affect and be affected by the organization in which it is being installed. The aim of this study was to examine the potential ...
Aller, Raymond - - 2009
* Pathology and clinical laboratories produce many types of data and information that are of relevance in protecting the health of the public. Electronic linkages between laboratory/pathology information systems and public health surveillance databases help ensure that these data reach the appropriate responder rapidly, completely, and accurately. Many efforts are ...
Sintchenko, Vitali - - 2009
* Context.--Traditional biothreat surveillance systems are vulnerable to incomplete and delayed reporting of public health threats.
Furuya, Keizo - - 2009
To cope with recent advances in radiologic imaging technology, a corresponding method for pathomorphologic demonstration should be developed to promote better understanding of radiologic-pathologic correlation. We attempted to obtain gross and microscopic images by using a 3-dimensional analytic tool and virtual microscopy and to link these images with multidetector computed ...
Hess, Jay - - 2009
The field of hematopathology has been a leader in the application of new technologies for both diagnostics and therapy. The ready accessibility of blood cells for examination, the ability to quantify important indices, and the relative responsiveness of otherwise fatal hematologic diseases to chemotherapy have all contributed to rapid advances ...
Ueng, Shir-Hwa - - 2009
* Context.--Interpretation of papillary lesions of the breast remains a challenging task because of the wide morphologic spectrum encountered in the benign, atypical, and malignant subtypes. Data on clinical significance and outcome of papillary lesions, with superimposed atypia or areas similar to ductal carcinoma in situ partially replacing the benign ...
Moinfar, Farid - - 2009
* Context.--More than 25 years ago, John G. Azzopardi described a distinctive intraepithelial neoplastic breast lesion, which he designated "clinging carcinoma in situ"; he considered it as another variant of ductal carcinoma in situ, an early lesion that can easily be missed because the changes are mainly cytologic rather than ...
Sahin, Aysegul - - 2009
* Context.--The presence or absence of metastases in axillary lymph nodes is one of the most important prognostic factors for patients with breast cancer. During the past decade sentinel lymph node (SLN) biopsy has been increasingly adopted as a minimally invasive staging alternative to complete axillary node dissection.
Rakha, Emad - - 2009
Context.--Advances in the understanding of the molecular and genetic mechanisms of breast cancer have led to realization of the heterogeneity of the disease and the promise of a new era of individualized management for patients with breast cancer. The advent and use of high-throughput molecular methods for the study of ...
Kim, Chungyeul - - 2009
* Context.--Gene expression-based prognostic assays for breast cancer are now available as commercial reference laboratory tests covered by insurance.

Repetitive exposure of skin to sunlight is known to result in dermatoheliosis, characterized by photoaging and carcinogenesis. It has been demonstrated previously that relatively large amounts of ultraviolet (UV) A can produce photodamage and it is believed that UVB plays a major role in the induction of photodamage and photo ...

Fibromyalgia is a chronic rheumatismal disease characterized by widespread pain and fatigue with unknown etiology. Subtle alterations of the neuroendocrine system in fibromyalgia syndrome have been proposed as a shared pathway linking numerous etiological and perpetuating processes with symptoms and observed physiological abnormalities. The role of neurohormonal mechanisms in the ...

Osteoarthritis is the most common form of arthritis and a worldwide health problem. Many institutes and centers have been conducting research studies for years about the advantages of glucosamine sulphate derivatives and chondroitin sulphate on pain and deformities caused by osteoarthritis. The results of the research studies mentioned are discussed ...

Antiphospholipid syndrome (APS) and multiple sclerosis (MS) are two diseases that may show similar clinical and radiological findings and sometimes cause confusion. In the presence of thrombosis, repetitious abortion history, and lupus anticoagulant antibodies or anticardiolipin antibodies, APS should be considered. However, in previous studies, autoantibody levels were detected as ...
