在糖尿病患者中所见到的甲改变可分为感染性、血管性、神经病性和其它类型.感染感染性疾病组的发生率极高,其病因可能是细菌或真菌.细菌类包括绿脓杆菌,金黄色葡萄球菌、大肠杆菌、普通变形杆菌等.这类感染通常是急性的,引起近端和侧面甲褶的甲沟炎,可致部分或整个甲母的破坏,继以持久的甲板异常.此外,急性病变可累及近端甲褶与甲床,导致甲暂时性生长障碍,表现为甲表面的横行凹陷(Beau线).甲细菌感染的另一种表现是甲床与上覆的甲板分离.呈淡绿黑色的甲变色,可能由假单孢菌属移生所致.这种损害尽管可持续性地进行保守治疗,仍应作X线检查以除外骨髓炎.与糖尿病有关的感染中,以真菌感染最 A change seen in patients with diabetes can be divided into infectious, vascular, neuropathic and other types of infectious diseases, the incidence of extremely high incidence of etiology may be bacteria or fungi bacteria include Pseudomonas aeruginosa , Staphylococcus aureus, Escherichia coli, Proteus vulgaris, etc. Such infections are usually acute and cause paronygias of the proximal and lateral nails, which can cause damage to some or all of the nauplii, followed by long-lasting deformities In addition, acute lesions can involve the proximal nail fold and the nail bed, resulting in a temporary growth disturbance, manifested as a Beau line on the surface of the nail.Another manifestation of a bacterial infection is the nail bed with overlying decks Isolated. A pale green-black hypochromism, possibly caused by Pseudomonas, which, despite sustained and conservative treatment, is still subject to X-ray examination to exclude osteomyelitis.
