Abstract：
UNASSIGNED: To investigate the hypotheses that in patients with SSc, the temperature gradient between the dorsum of the foot and toes (distal-dorsal difference [DDD]) is \'more negative\' (toes cooler) than in healthy controls, is greatest along the first (great) toe and that the severities of thermographic abnormalities in the feet and hands are correlated.
UNASSIGNED: Thermographic images of the dorsum of each hand and foot were captured using a thermal camera attached to an iPhone in 40 patients with SSc and 20 healthy controls. DDDs along the fingers (index, middle, ring and little) and toes (great toe and \'others\') were measured.
UNASSIGNED: There was a non-significant trend for the great toes to be colder in patients with SSc than in controls. The mean great toe DDD was more negative in patients (right: -2.89°C, left: -2.91°C, mean: -2.90°C) than in controls (right: -2.36°C, left: -2.42°C, mean: -2.39°C) (P = 0.37 for mean values). Patients\' great toes were colder than \'other\' (lesser) toes (right: -2.58°C, left: -2.63°C), although not significantly. In patients with SSc, finger and great toe temperature gradients were correlated (r = 0.406, ρ = 0.01).
UNASSIGNED: Our findings suggest that the great toe is the coldest in patients with SSc and that patients with the coldest fingers tend to have the coldest toes. Severe RP symptoms in the hands should prompt podiatry assessment and foot care education. Mobile phone thermography is a convenient tool for assessing the digital vasculature but first requires validation in larger studies with a longitudinal component.

摘要：
■为了研究SSc患者的假设，与健康对照组相比，脚部和脚趾背侧之间的温度梯度（远侧-背侧差[DDD]）为“更负”（脚趾更冷），在第一（大）脚趾上最大，并且脚和手的热成像异常的严重程度是相关的。
■使用连接到iPhone的热像仪捕获了40名SSc患者和20名健康对照者的每只手脚背部的热成像图像。沿着手指的DDDs(食指，中间,测量环和小）和脚趾（大脚趾和“其他”）。
■SSc患者的大脚趾比对照组冷的趋势不明显。患者的平均大脚趾DDD更阴性（右：-2.89°C，左：-2.91°C，平均：-2.90°C）比对照组（右：-2.36°C，左：-2.42°C，平均值：-2.39°C）（平均值P=0.37）。患者\'大脚趾比\'其他\'（较小）脚趾更冷（右：-2.58°C，左:-2.63°C),虽然不是很重要。在SSc患者中，手指和大脚趾温度梯度相关（r=0.406，ρ=0.01）。
■我们的研究结果表明，大脚趾是SSc患者中最冷的，手指最冷的患者往往脚趾最冷。手部严重的RP症状应提示足病评估和足部护理教育。手机热成像是评估数字脉管系统的便捷工具，但首先需要在具有纵向分量的大型研究中进行验证。
