CONTEXT Naphyrone (naphthylpyrovalerone) is a cathinone derivative and recreational drug related to mephedrone. CASE We report a 31-year-old man who ingested a dose of naphyrone (100 mg), which produced acute sympathomimetic toxicity with restlessness, insomnia, anxiety, and hallucinations lasting for 2 days. Naphyrone was detected in the patient's plasma(More)
BACKGROUND AND OBJECTIVE Phenotyping cocktails use a combination of cytochrome P450 (CYP)-specific probe drugs to simultaneously assess the activity of different CYP isoforms. To improve the clinical applicability of CYP phenotyping, the main objectives of this study were to develop a new cocktail based on probe drugs that are widely used in clinical(More)
The mutation cluster region (MCR) of adenomatous polyposis coli (APC) is located within the central part of the open reading frame, overlapping with the region encoding the 20 amino acid repeats (20R) that are beta-catenin-binding sites. Each mutation in the MCR leads to the synthesis of a truncated APC product expressed in a colorectal tumour. The MCR(More)
In this work, we investigated whether activity routines of stroke rehabilitation patients can be discovered from body-worn motion sensor data and without data annotation using topic modeling. Information about the activity routines performed by stroke patients during daily life could add valuable information to personal therapy goals. As topic model input,(More)
We report on a patient with Pneumocystis jirovecii pneumonia who developed fever, rash, eosinophilia and hepatitis 10 days after initiation of a therapy with sulfamethoxazole and trimethoprim. A DRESS syndrome was diagnosed and the therapy was changed successfully to pyrimethamine and dapsone. We describe the clinical picture, causative drugs, pathogenesis,(More)
BACKGROUND AND OBJECTIVE Activity of human cytochrome P450 enzymes (CYPs) shows high inter-and intra-individual variability, which is determined by genetic and non-genetic factors. Using a combination of CYP-specific probe drugs, phenotyping cocktails allow simultaneous assessment of the activity of different CYP isoforms. The objective of this study was to(More)
BACKGROUND Monitoring natural behavior and activity routines of hemiparetic rehabilitation patients across the day can provide valuable progress information for therapists and patients and contribute to an optimized rehabilitation process. In particular, continuous patient monitoring could add type, frequency and duration of daily life activity routines and(More)
We present a motion-adaptive duty-cycling approach to estimate orientation using inertial sensors. In particular, we deploy a proportional forward-controller to adjust the duty-cycle of inertial sensing units (IMU) and the orientation estimation update rate of an extended Kalman filter (EKF). In sample data recordings and a simulated daily life dataset from(More)
We report on a 16 year old patient with a hemorrhagic bullous form of a Henoch-Schönlein purpura. The cause for the event could not be determined, but the patient recovered without complications. Since he had begun a therapy with isotretinoin due to an acne inversa 3 weeks before, a possible association between the event and the treatment could not be(More)
