Nephrogenic systemic fibrosis has been shown to cause these lesions in the lungs, pleura, diaphragm, myocardium, pericardium, and dura mater, the presence of which are typically indicative of severe progression of NSF. In cases where the lesions are manifest in the periarticular tissue, joint contractures

and restricted range of motion can often result. We provide a quick synopsis of NSF, and a short case study that describes the authors’ experience with one of their patients who requested a surgical consult as a result of being wheelchair-bound due to NSF’s sequelae.

“Background and Objectives: selleckchem The Pain Sensitivity Questionnaire (PSQ) is predictive of pain-related responses to experimental stimuli in German-speaking individuals. Here, we explored the validation of the English translation of the PSQ (PSQ-E). Methods: One hundred thirty-six patients scheduled to undergo a low back interventional procedure completed BML-275 2HCl the PSQ-E and other questionnaires including the Brief Pain Inventory. Pain ratings on a visual analog scale (VAS) were obtained following 2 standardized injections

of subcutaneous lidocaine (VAS 1, infiltration in hand; VAS 2, infiltration of procedural site). The VAS measures were compared with the PSQ-E data and other inventories using linear regression analysis with stepwise selection of variables. Results: The PSQ-E properties were in all respects similar to those of the original German PSQ. VAS 1 magnitude was predicted by PSQ-E-minor Momelotinib solubility dmso (r = 0.26,

P smaller than 0.01). VAS 2 magnitude was predicted by PSQ-E-minor (r = 0.34, P smaller than 0.001), and the prediction was significantly enhanced by further inclusion of the Brief Pain Inventory interference score (total r = 0.40, P smaller than 0.001). Conclusions: The study demonstrated that a significant correlation exists between the PSQ-E and clinically relevant pain ratings. This study validates the PSQ-E both in terms of measuring pain sensitivity and as possible means of recognizing patients with high pain sensitivity. Defining this subset of patients may have clinical utility in the future.”
“BACKGROUND: Attacks of neuropathic pain, usually abdominal, are characteristic of the acute porphyrias and accompanied by overproduction of heme-precursor molecules, specifically delta-aminolevulinic acid and porphobilinogen. The basis for the acute symptoms in these diseases has been speculative. METHODS: We review genetic acute porphyria, hereditary tyrosinemia, and an acquired condition, lead poisoning. All perturb heme synthesis and present with a similar pain syndrome. RESULTS: Although each of these conditions has characteristic urine biochemistry, all exhibit excess delta-aminolevulinic acid. Moreover, in all, treatment with hemin reduces delta-aminolevulinic acid and relieves symptoms. In contrast, use of recombinant porphobilinogen deaminase to knock down porphobilinogen in acute porphyria was ineffective.
