Discordant SOX-1 antibodies results in paraneoplastic Lambert-Eaton syndrome diagnosis by the clinical laboratory.

Background: Anti-Sry-like high mobility group box 1 (anti SOX-1) proteins are rare onconeural antibodies associated with paraneoplastic Lambert-Eaton myasthenic syndrome (LEMS). Few patients with anti-SOX-1 antibodies and negative anti-glial nuclear antibody reactivity have been described to date.

Case Subject And Methods: Our case involves a 72-year-old female patient with progressive girdle weakness, sensation of heaviness in the lower limbs, predominantly distal and associated with circulatory problems together with instability when walking, with a high suspicion of an autoimmune myopathic disorder.

Computer physician order entry (CPOE) as a strategy to estimate laboratory activity and costs associated with cancer clinical trials.

Introduction: Most of clinical laboratories are not properly reimbursed for their activity related to clinical trials (CTs) conducted in their institutions due to a lack of measurement strategies. We implemented a specific computer physician order entry (CPOE) environment for CTs in order to facilitate ordering to providers and estimate the associated costs to be compared with the standard of care (SOC).

Materials And Methods: Four specific electronic formularies, restricted to two new virtual CTs clinical services (onco - CT and haemo - CT), were implemented in January 2015.

"Send & hold" clinical decision support rules improvement to reduce unnecessary testing of vitamins A, E, K, B1, B2, B3, B6 and C.

Background: We assessed the impact of several "send & hold" clinical decision support rules (CDSRs) within the electronical request system for vitamins A, E, K, B1, B2, B3, B6 and C for all outpatients at a large health department.

Methods: When ordered through electronical request, providers (except for all our primary care physicians who worked as a non-intervention control group) were always asked to answer several compulsory questions regarding main indication, symptomatology, suspected diagnosis, vitamin active treatments, etc., for each vitamin test using a drop-down list format.

Utility of routine laboratory preoperative tests based on previous results: Time to give up.

Introduction: The usefulness and cost-effectiveness of routine laboratory preoperative tests (POTs) have been challenged recently. In fact, the American Society of Anesthesiologists (ASA) Task Force has stated that test results obtained from the medical record within 6 months of surgery generally are mostly acceptable. The aim of our study was to evaluate the degree of utility of POTs and their clinical benefit based on this recommendation.

Failure to review STAT clinical laboratory requests and its economical impact.

Background: Failure to follow-up laboratory test results has been described as one of the major processes contributing to unsafe patient care. Currently, most of the laboratories do not know with certainty not only their rate of missed (or unreviewed) requests but the economical cost and impact that this issue implies. The aim of our study was to measure that rate and calculate the resulting costs.
