Reliability and validity of the Italian version of the Chronic Pain Grade questionnaire in patients with musculoskeletal disorders.
The aim of this study is to analyse the psychometric properties of the Italian version of the Chronic Pain Grade (CPG) questionnaire within a population of chronic musculoskeletal pain patients. The CPG questionnaire was adapted following the translation and back-translation methodologies. There were 576 patients with chronic musculoskeletal pain. ⋯ Discriminant validity, assessed by comparing the CPG dimensions in patients with and without other health conditions, showed that the CPG shows moderate association with the presence of co-morbidities. Furthermore, the CPG Disability Score was inversely correlated (p=0.01) to years of formal education. In conclusion, the Italian version of the CPG questionnaire has shown to be valid and reliable for evaluating the severity of chronic musculoskeletal pain, with metric properties in agreement with the original, widely used version.

Clinical TrialTreatment of complex regional pain syndrome type I of the hand with a series of intravenous regional sympathetic blocks with guanethidine and lidocaine.
The aim of this study was to evaluate the efficacy of guanethidine and lidocaine in the treatment of complex regional pain syndrome (CRPS) type I of the hand. Seventeen patients, aged between 33 and 72 years, suffering from CRPS type I of the hand received two series of intravenous regional sympathetic block (Bier's block) sessions with guanethidine and lidocaine according to the following therapeutic protocol: (1) 5 sessions (once every second day) composed of intravenous regional administration of 15 mg guanethidine and 1 mg lidocaine/kg body weight each and (2) 20 sessions (twice a week) composed of intravenous regional administration of 10 mg guanethidine and 1 mg lidocaine/kg body weight each. ⋯ No side effects were observed. The above-described therapeutic protocol method resulted in excellent pain relief and full restoration of both function and range of movement of the affected extremity in 17 patients suffering from CRPS type I of the hand.

Toxic effects of povidone-iodine on synovial cell and articular cartilage.
The objective of this study was to investigate the toxic effects of povidone-iodine (PVI). A series of MTT assay of cultured synovial cells stimulated by PVI have been made. Test for assay of membrane-toxic effect of PVI and lactate dehydrogenase (LDH) has also been carried out. ⋯ Fibrin deposition has been observed even in the synovium of 1-day stimulation. On the 7th day, a serum total iodine concentration has been 544 microg/dl, 4,440 IU/ml for CPK concentration, and 2,049 IU/ml for LDH concentration, while the control concentrations have been 7.1 microg/dl, 491 IU/ml, and 700 IU/ml, respectively. Our experiment has disclosed that PVI preparation is strongly cytotoxic to synovial cell and articular cartilage.

Randomized Controlled Trial Comparative StudyEfficacy of salmon calcitonin in complex regional pain syndrome (type 1) in addition to physical therapy.
The aim of the study was to assess the efficacy of salmon calcitonin, which was suggested as effective in the treatment of complex regional pain syndrome type 1 (CRPS 1). Patients who had suffered trauma to their upper extremities and developed CRPS 1 were included into this randomised, controlled single-blind study. The diagnosis was made according to the clinical examination and scintigraphy. ⋯ The control examination showed similar results for allodynia, hyperalgesia and trophic changes, whereas remarkable improvement was observed in the rest of the parameters within groups. On the other hand, between the two groups there was no significant difference in any of the parameters (p>0.05) This randomised, single-blind study showed that all of the patients with acute CRPS 1 in their upper extremities after trauma, who were treated with either paracetamol or calcitonin along with physical therapy, recovered in all parameters significantly, but without any difference between groups. We can conclude that calcitonin does not make any favourable contribution in the treatment of patients with acute CRPS 1; physical therapy combined with only a simple analgesic is an efficient means of therapy.
