Infantile hemangiomas (IHs) are benign lesions found in infants. Predicting the cosmetic outcome of these lesions is very difficult. Therefore, in this prospective study, we assessed whether using an infrared thermometer (IRT) to measure the surface temperature of IHs would help to predict their proliferative potential.
Between January 2012 and March 2014, we prospectively investigated 103 children up to 6 months of age with a diagnosis of IH. None of them required immediate treatment. Two projection plain photographs of the IHs were obtained and the temperature of the IH surface was measured with the IRT at each visit. The IHs in these patients were divided into three groups: stable, slightly growing and growing IHs. We analyzed temperature differences between the groups, relative operating characteristic (ROC) curves, and possible application of this method to clinical practice.
The median initial temperatures in the groups were 36.7°C for the stable group, 37°C for the slightly growing group, and 37.4°C for the growing group (P<0.01). The area under the ROC curve for the temperature values to predict growth was 0.929. Temperatures at or above 37.4°C showed a specificity of 95%, a sensitivity of 75%, a positive predictive value 81%, and a negative predictive value of 95%.
IRT is a time and cost effective tool, and is easy to learn. The surface temperature of IH reflects its remaining growth potential and could be used in the outpatient setting for the evaluation and follow-up of IH.
婴儿血管瘤（IHs）是在婴儿中发现的良性病变。预测这些病变的美容效果非常困难。因此，在这项前瞻性研究中，我们评估了使用红外温度计（IRT）测量IHs的表面温度是否有助于预测其增殖潜力。
在2012年1月至2014年3月期间，我们对103名6个月以下诊断为IH的儿童进行了前瞻性研究。他们均无需立即治疗。每次就诊时获取两张IHs的投影平片，并使用IRT测量IH表面温度。这些患者的IHs分为三组：稳定型、轻度生长型和生长型IHs。我们分析了各组之间的温度差异、相对操作特征（ROC）曲线以及该方法在临床实践中的可能应用。
稳定组的初始温度中位数为36.7°C，轻度生长组为37°C，生长组为37.4°C（P<0.01）。用于预测生长的温度值的ROC曲线下面积为0.929。温度在37.4°C及以上时，特异性为95%，敏感性为75%，阳性预测值为81%，阴性预测值为95%。
IRT是一种省时且经济高效的工具，易于掌握。IH的表面温度反映了其剩余的生长潜力，可用于门诊环境中IH的评估和随访。
