Acne keloidalis nuchae (AKN) is a chronic inflammatory dermatosis of the scalp that causes scarring alopecia. The etiology of AKN has been associated with an immune response vs. follicular antigens. AKN is characterized by fibrotic papules and plaques that can converge in tumor-like lesions; subclinical disease has been reported in perilesional areas, which could impact its development. Early diagnosis and treatment are essential to reduce morbidity and preserve and minimize healing. Various treatments have been established including optimal medical therapy, surgical excision, and light sources. An updated description of treatments (algorithm included) used for AKN is suggested based on the clinical lesions.

Background and aims
Previous results of the Dermatology-Life-Quality-Index (DLQI) validation in Colombia based on the classical test theory (CTT) perspective have showed the need to delve into its measurement properties. Therefore, we aimed to assess the structural validity, internal consistency and item response analysis of the DLQI through the item response theory (IRT) or the Rasch model.
Material and methods
We assessed the dimensionality of the DLQI, determined its difficulty, discrimination and differential functioning and went on to evaluate its internal consistency and discriminative validity among patients with inflammatory and non-inflammatory skin disease. We recruited Colombian patients with different skin diseases.
Results
Data of 865 patients (mean age, 49.3 years; 61% females) were included. DLQI-scores ranged from 0 up to 30. Internal consistency for dichotomous item #7 showed a McDonald's Omega coefficient of 0.85 (95%CI, 0.84–0.87) and a Cronbach's α coefficient of 0.86 (95%CI, 0.84–0.88). For ordinal item #7, the McDonald's Omega coefficient was 0.87 (95%IC: 0.85–0.89) and Cronbach's α coefficient, 0.84 (95%CI, 0.82–0.87). Horn's parallel analysis revealed the presence of DLQI unidimensionality with a 1-factor solution. Only item #1 fitted the PCM model. The remaining items, including item #9, did not show adequate fit due to overlapping responses and order changes.
Conclusions
The validity of DLQI-COL based on Rasch analysis proved not to be a suitable instrument to evaluate QoL in our dermatologic population. A refined version of the scale with an adequate cross-cultural adaptation and validation process is needed to obtain an appropriate and reliable version of the instrument for QOL measuring in Colombian patients with skin diseases.
