Multivariate analysis of favtors associated with early onset segmental and nonsegmental
vitiligo: a prospective observational study of 213 patients.
Basically, two types of compression pump exist: segmental, also called sequential or dynamic, and static or nonsegmental
. Static PC involves the affected limb with a single continuous high-pressure chamber, which compresses the entire limb at once.
The Efficacy of Pimecrolimus1% Cream Combined with Microdermabrasion in the Treatment of Nonsegmental
Childhood Vitiligo: A Randomized Placebo-Controlled Study.
According to a recent international consensus conference, vitiligo can be classified into two major forms: nonsegmental
vitiligo (NSV) and segmental vitiligo (SV, accounts for 5-16% of all vitiligo cases).
This is a particular issue because biopsies are often taken when patients are suspected of having idiopathic pulmonary fibrosis; however, the classic peripheral, lower lobe-predominant, nonsegmental
honeycomb fibrosis (68) is absent or the radiographic findings overlap with other processes causing fibrosis.
Combination Vitiligo: Rarely segmental and nonsegmental
types occur in same patient.

vitiligo," International Journal of Dermatology, vol.
Regarding type of vitiligo, nonsegmental
vitiligo was the most common in this study (N = 321,79.9%) followed by segmental vitiligo and focal vitiligo, 64 (15.9%) and 17 (4.2%), respectively.
Teulings and colleagues from the department of dermatology and the Netherlands Institute for Pigment Disorders at the University of Amsterdam presented a retrospective analysis of seven patients diagnosed with MAL from 2009-2014, who had been initially diagnosed with nonsegmental
in 2003 and they mentioned that nonsegmental
vitiligo (NSV) occurs due to "melanocytorrhagy" or a chronic melanocyte detachment and loss caused by trauma and other stressors including catecholamines, ROS, or autoimmune elements .
The polymorphism at position -1305, also very frequent among the 1000 Genomes populations, was associated with nonsegmental
