    ABSTRACT: To validate a Spanish version of the Northwick Park Neck Pain Questionnaire (NPQ) and to prove its usefulness in clinical practice. We studied 58 patients with non-inflammatory neck pain of more than 4 months duration. A blind back translation of the NPQ was made, and the resulting back-translation version was then compared with the original. The NPQ comprises 9 questions with 5 statements of increasing difficulty. Patients completed the questionnaire 3 times: on their initial assessment; 8-10 days later (test-retest); and after physiotherapy treatment 3 months later. Neck pain was assessed by a visual analogue scale (VAS). Fifty-three patients completed the questionnaire (90%). There was a good intra-class correlation between the test-retest NPQ (r = 0.63), indicating good agreement. For each of the 9 sections, agreement ranged from r = 0.43 to r = 0.85, p < 0.05 in all cases. Correlation with the VAS was also good, between r = 0.51 (test) and r = 0.74 (retest) (p < 0.05 in all cases). Pain measured by the VAS increased according to the NPQ score, grouped by percentages (p = 0.003). The mean scores for each section increased with that of the intensity of pain, in most sections showing good internal consistency. Pain and the NPQ score improved after treatment (56.1 +/- 20.2 to 29.9 +/- 20.1, p = 0.0001 and 45.9% +/- 12.7% to 28.9% +/- 15.3%, p = 0.0001 respectively), as did all the other items except for driving (p < 0.05). The Spanish version of the NPQ is a feasible, reliable and valid instrument to measure pain in Spanish-speaking patients with chronic neck pain.

    ABSTRACT: We studied the prevalence and significance of erosive azotemic osteoarthropathy (EAO) and its relationship with other osteoarticular abnormalities of dialysis-associated arthropathy (DAA). 112 patients undergoing maintenance dialysis were studied: 63 hemodialysis (HD) and 49 continuous ambulatory peritoneal dialysis (CAPD). X-ray of the hands, shoulders, pelvis and cervical spine were examined for destructive spondyloarthropathy (SDA), bone cysts (BC), EAO and subperiosteal resorption. Beta 2-microglobulin (beta 2-m) and PTH were also measured. Fifteen patients (13%) had EAO, usually in several joints of the hands, DIPs being the most frequently affected. Both patients on HD and those on CAPD had EAO, although the prevalence was higher in the HD group, 12 (19%) vs. 3 (6%). Patients with EAO were older (p < 0.05) and had more carpal tunnel syndrome (CTS) (p < 0.05) and BC (p < 0.01). Only 3 out of 15 patients with EAO had severe secondary hyperparathyroidism (sHPTH) (PTH > 500), while 9/15 had neither radiologic nor laboratory evidence of sHPTH. No differences were found regarding the duration of dialysis, or beta 2-m or PTH level. EAO is not related to sHPTH and should be included within the spectrum of the clinical manifestations of DAA. Due to its location and radiologic picture, it is possible that etiologic factors leading to primary osteoarthritis may play a role in the development and evolution of EAO.

    ABSTRACT: One hundred and one first degree relatives of 35 patients with chondrocalcinosis were examined for the presence of familial disease. Eleven subjects from nine families showed radiological chondrocalcinosis, a prevalence of familial disease of 26%. Two different patterns of disease were noted--the older generation was more commonly affected, and the younger generation and second degree relatives were exempt. Clinical and radiological differences were found between the early and late onset groups, but not between late onset and sporadic forms of chondrocalcinosis. These findings support the suggestion that the true prevalence of familial disease. is underestimated. A dominant, autosomal transmission with variable penetrance is consistent with our findings, which suggests that homozygous patients with familial chondrocalcinosis may present a more severe form of the disease.
