Methylphenidate-associated myopathy

Pediatric Rheumatology, 2012
Methods We describe a case of a 13 yo girl diagnosed with ADHD since early childhood, in MP use for the past 3 years. She complained about a mild discomfort of proximal muscles of the lower limbs and cramps for the previous 3 months. Routine exams revealed increased aminotransferases levels (AST 192 UI/L; ALT 222 UI/L), suggesting hepatotoxicity.

Multianalyte Approach—Including Automated Preparation of Calibrators—for Validated Quantification of 82 Drugs in Whole Blood by Liquid Chromatography–Tandem Mass Spectrometry

Drug Testing and Analysis, EarlyView.
In forensic bioanalysis, often multianalyte approaches are used given their increased effectiveness but can be difficult to develop and maintain in the laboratory, for example, in terms of calibrator solution preparation. A fast, simple, and robust liquid chromatography–tandem mass spectrometry (LC–MS/MS) method for the quantification of 82 classic ...

UHPLC‐QTOFMS Urine Drug Screening With Dilute‐and‐Shoot Sample Preparation and Vacuum‐Insulated Probe‐Heated Electrospray Ionization

Drug Testing and Analysis, EarlyView.
The new ionization technique, vacuum‐insulated probe‐heated electrospray, allows for a simple dilute‐and‐shoot sample preparation to be used with liquid chromatography time‐of‐flight mass spectrometry in urine drug screening. Comparison with a method relying on solid‐phase extraction and conventional electrospray ionization shows improved performance ...

Workplace Drug Testing—Prevalence of Positive Test Results, Most Common Substances, and Importance of Medical Review

Drug Testing and Analysis, EarlyView.
Among 23,900 urine and oral fluid drug tests from Swedish workplaces, 4.6% tested positive for controlled substances. Cannabis, amphetamine, cocaine and benzodiazepines were most common. Many samples containing opiates, amphetamine or benzodiazepines were MRO verified as being due to medical prescriptions, while cannabis or cocaine were almost entirely
