Necrotizing Granulomatous Dermatitis and Panniculitis Masquerading as T Cell Lymphoma.

A 51-year-old white woman with a past medical history significant for steroid-dependent ulcerative colitis, rheumatoid arthritis, and diabetes mellitus presented to the hospital with fever and painful, erythematous subcutaneous nodules on the medical aspects of both thighs. Histopathologic examination showed features suggestive of an abscess, but her condition failed to improve with intravenous broad-spectrum antibiotics. Molecular studies detected T cell receptor-β gene rearrangements.

Constitutional risk factors for focal neuropathies in patients referred for electromyography.

Background And Purpose: It is well established that patient-related constitutional features predispose to focal peripheral neuropathies. Some of these risk factors were investigated in common focal neuropathies encountered in patients referred for electromyography.

Methods: Gender, age, height and body mass index (BMI) were analysed retrospectively as risk factors for 11 focal neuropathies.

Standards for quantification of EMG and neurography.

This document is an update and extension of ICCN Standards published in 1999. It is the consensus of experts on the current status of EMG and Neurography methods. A panel of authors from different countries with different approach to routines in neurophysiological methods was chosen based on their particular interest and previous publications.

GPR40 is a low-affinity epoxyeicosatrienoic acid receptor in vascular cells.

Endothelium-derived epoxyeicosatrienoic acids (EETs) have numerous vascular activities mediated by G protein-coupled receptors. Long-chain free fatty acids and EETs activate GPR40, prompting us to investigate the role of GPR40 in some vascular EET activities. 14,15-EET, 11,12-EET, arachidonic acid, and the GPR40 agonist GW9508 increase intracellular calcium concentrations in human GPR40-overexpressing HEK293 cells (EC = 0.

Nerve conduction study of the three supraclavicular nerve branches.

Introduction: We describe a new nerve conduction study technique with reference values for the 3 branches of the supraclavicular nerve (SCN) in young healthy subjects and application of it in 2 patients.

Methods: The recording electrode was placed on the posterior border of the sternocleidomastoid muscle, 6-7 cm from the sternoclavicular joint. SCN branches were stimulated below the clavicle, 2.
