Joint laxity in canine hip dysplasia assessed using the hip flexed not distracted ventrodorsal view.

OBJECTIVES: The ventrodorsal hip extended standard view is conventionally used for radiographic screening of canine hip dysplasia. However, because the ventrodorsal hip extended standard view minimises hip joint laxity, several alternative views have been proposed. Our aim was to evaluate a new ventrodorsal hip flexed and not distracted view to assess joint laxity, by comparing it with the ventrodorsal hip extended standard and ventrodorsal hip flexed and distracted views. MATERIALS AND METHODS: Between April 2013 and March 2017, all dogs referred to the University of Naples "Federico II" for the diagnosis of canine hip dysplasia were studied using the ventrodorsal hip extended standard, ventrodorsal hip flexed and not distracted and ventrodorsal hip flexed and distracted views. The Norberg angle and the laxity index were measured for each view. RESULTS: Overall, 102 dogs, 67 males and 35 females, mean age 15 months, were included. The mean (±standard deviation) Norberg angles were 99.77° (±10.42°), 89.29° (±14.32°) and 91.80° (±13.50°) for the ventrodorsal hip extended standard, ventrodorsal hip flexed and not distracted and ventrodorsal hip flexed and distracted views, respectively. The mean (± standard deviation) laxity indices were 0.19 (± 0.14), 0.39 (± 0.25) and 0.36 (± 0.21), respectively. The ventrodorsal hip flexed and distracted and ventrodorsal hip flexed and not distracted views had lower Norberg angle and higher laxity index values compared with the ventrodorsal hip extended standard view. The ventrodorsal hip flexed and distracted and ventrodorsal hip extended standard views are in strong agreement for the measurement of both Norberg angle and laxity index, as confirmed by Bland-Altman analysis and the intraclass correlation coefficient. CLINICAL SIGNIFICANCE: The ventrodorsal hip flexed and distracted and ventrodorsal hip flexed and not distracted views obtained with the hip in a neutral position reveal joint laxity better than the ventrodorsal hip extended standard view. Unlike the ventrodorsal hip flexed and distracted view, the ventrodorsal hip flexed and not distracted view does not require human operators or special devices for positioning the dog. The wide age range of the dogs enrolled might have influenced the laxity index measurements, since capsular fibrosis in older dogs reduces laxity.

Management of cutaneous discomfort in patients with scleroderma: a clinical trial.

Systemic sclerosis (scleroderma) is a disease of unknown cause, the hallmark of which is induration of the skin. This bad condition of the skin influences negatively the quality of life of patients with scleroderma. The aim of the study was to verify the efficacy of two formulations, specifically designed to wash, moisturize and soothe the scleroderma skin. An independent, randomized, double blind, controlled trial was conducted in the Department of Rheumatology of "A. Galateo" Hospital in San Cesario di Lecce. Forty-six women affected by scleroderma, and treated with Iloprost every month, were divided into two groups: group 1 followed a specific treatment with cleansing formulation only, group 2 followed a combined treatment with the cleansing solution and the moisturizing solution. In addition, a third group was evaluated: 14 women, who did not undergo intravenous Iloprost therapy, were treated simultaneously with the cleansing formulation and the moisturizing formulation. The three treatments lasted for 4 weeks. Reduction in trans epidermal water loss (TEWL), increase in moisturization of the stratum corneum, reduction in Skin Score and improvement in quality of life were assessed. Very significant improvement in quality of life occurred in each group. Group 2 obtained very significant improvement in hydration and reduction in skin score and TEWL. The study showed that the daily use of both formulations proved to be effective in washing, hydrating and soothing the skin of patients with scleroderma, especially in association with Iloprost therapy.
