Background
The FricTest is used as a valuable tool for diagnosing and conducting threshold testing for Symptomatic Dermographism (SD).
Objective
In this study, the authors aimed to make a comparison between the Urticaria Activity Score (UAS), Urticaria Control Test (UCT), Visual Analog Scale (VAS), Dermatology Life Quality Index (DLQI), and Chronic Urticaria-Specific Quality of Life (CU-QoL) used to evaluate disease activity and control in the follow-up of urticaria patients and the Fric Test responses used in the diagnosis of dermographism.
Methods
71 patients with SD were included in the study. Fric test 4.0 was performed in all patients at baseline and at month 1. The correlations of Fric test scores with UCT, UAS, VAS, DLQI, and CU-QoL at baseline as well as the changes in responses of treatment in the mean scores at month 1 were performed.
Results
In the correlation analyses, positive correlations were observed between UAS, DLQI, and CU-QoL scores and changes in Fric test 4.5 mm and 4 mm responses from baseline to the first month of treatment (p < 0.05). No significant correlations were found between Fric test 3.5 mm and 3 mm responses and CU-QoL, UAS, DLQI, and VAS scores (p > 0.05).
Study limitations
This study includes results from a small sample size, and larger-scale clinical trials are needed.
Conclusion
Changes in the Fric test 4.5 mm and 4 mm responses of treatment were found to be more sensitive in detecting UCT, UAS, CU-QoL, and DLQI changes than the responses of the Fric test 3.5 mm and 3 mm.

Background
Artificial intelligence (AI) is increasingly gaining ground in dermatology, with studies reporting accuracy equal to or greater than dermatologists for the diagnosis of skin lesions from clinical and dermoscopic images.1 AI has been developed and improved constantly for dermatology, however, the focus has been much more on neoplastic diseases, due to their high prevalence and high morbidity.
Objectives
Describe the possible applications of AI in inflammatory dermatoses.
Methods
Articles published between 2013 and 2023 in Medline and Lilacs were retrieved after applying the inclusion and exclusion criteria 19 articles were selected. From each selected article, the necessary information was extracted and with this data, the present review was written.
Results
The first studies on AI in dermatology focused on the diagnosis of neoplasms, especially melanoma, due to the ease of standardization of images, obtaining accuracy equivalent to that of a dermatologist in clinical and dermoscopic lesions. Actually, there are many studies on artificial intelligence in inflammatory dermatosis, such as psoriasis, helping to calculate the PASI, hidradenitis suppurativa, and atopic dematitis.
Study limitations
The limitation of the study is that it is a literature review and because it is an innovative topic with a limited number of studies published in the literature.
Conclusions
Considerable of what is published in the literature is in computer science journals, but it is possible to perceive that there is an important interest in the area and that artificial intelligence will advance to assist dermatologists.

Background
Rosacea is the most prevalent chronic vascular-inflammatory dermatosis of the face. Its pathogenesis includes genetic and environmental factors, neurovascular alterations, and innate immunity. Many triggering and aggravating factors, as well as systemic comorbidities, have been associated with the disease, but there are few studies on its epidemiology in Brazil.
Objectives
To describe the profile of patients with rosacea treated at referral centers, as well as to investigate the presence of comorbidities, dietary aspects, worsening factors, and quality of life.
Methods
Cross-sectional and multicenter Brazilian study. Clinical and demographic data, disease severity, triggering and/or aggravating factors, diet, comorbidities, and impact on quality of life were evaluated.
Results
258 patients were included, predominantly women, between 35 and 65 years old and phototypes III, IV and II. The clinical picture ranged from mild to moderate in 89% of cases and quality of life was reasonable to slightly affected in 58% of cases. Aggravating factors for rosacea were reported by 96% of patients, with climate exposure, alcoholic beverages, and emotional changes being the most frequent. Among the foods mentioned as aggravating factors (28%), pepper, other condiments and hot beverages were the most frequently reported. Comorbidities were reported by 89% of the participants, with emphasis on endocrine (48%), psychiatric (35%), cardiovascular (31%) and gastrointestinal (28%) diseases.
Study limitations
Uncontrolled study, including patients undergoing dermatological treatment.
Conclusions
This study establishes that the profile of Brazilian patients with rosacea corroborates that described in the literature, with the presence of the disease in higher phototypes being relevant. Pepper and other condiments and hot beverages were important aggravating factors, and the presence of various comorbidities was reported by most of the patients.

Xeroderma pigmentosum (XP) is an autosomal recessive genetic disorder characterized by a defect in the nucleotide excision repair (NER) pathway, responsible for repairing DNA damage induced by ultraviolet rays. The most common symptom in affected patients is an increased photosensitivity associated with early development of cutaneous and internal malignancies.
Objective
To describe whether the follow-up of xeroderma pigmentosum patients using total body mapping (TBM) with digital dermoscopy (DD) and in vivo reflectance confocal microscopy (RCM) increases early detection of melanoma and reduces unnecessary biopsies of benign melanocytic lesions.
Methods
Twelve XP patients were followed-up with TBM and DD from February 2008 until March 2020. The number of melanocytic lesions excised (NNE) was counted before and after the surveillance with TBM, DD, and RCM.
Results
In the 12-year surveillance period, twelve XP patients were followed-up with TBM, DD, and RCM. The proportion of thinner and in situ melanomas diagnosed increased after the implementation of TBM and DD in the follow-up of this group (from 67% to 82%). The association of technologies caused a reduction in the NNE from 4.02 to 2.88 and promoted early detection of melanoma.
Study limitations
Maintaining regular follow-up with some XP patients can be challenging due to comorbidities and social issues. Although XP is a rare disease, this represents an especially small number of cases.
Conclusion
XP patients are generally submitted to multiple surgical excisions, with high morbidity. Based on this experience, TBM, DD and RCM have improved the early detection of melanoma and reduced the NNE with a positive impact on health and quality of life.

Background
Superficial infection in venous ulcers (VU) hinders healing.
Objective
To evaluate the action of hydrofiber dressing with silver (HAg) compared to collagenase ointment (Col) in VU.
Methods
Randomized controlled clinical trial in which patients with VU with superficial infection were randomized to the intervention (HAg) or comparison (Col) group. After 30 days (T30), the primary outcomes evaluated were: rate of ulcers without signs of superficial infection, decrease in bacterial load, presence of biofilm-producing bacteria, and bacterial clonality.
Results
Thirty-four patients (56 ulcers) were included ‒ 18 patients (28 ulcers) in the HAg group and 16 (28 ulcers) in the Col group. There was a reduction in ulcers with superficial infection in both groups over time but with no differences (p = 0.422). There was no decrease in total bacterial load over time (p = 0.054) or between the groups (p = 0.113). There was a reduction in the rate of ulcers with biofilm-forming bacteria over time (p = 0.047) but no differences between groups (p = 0.558). Regarding the clonality of Staphylococcus aureus, 92.8% of ulcers in the HAg group and 85% in the Col group, the clones identified at T0 were the same at T30 (p = 0.553). There was no change in the identity of Pseudomonas aeruginosa in any ulcer in either group.
Study limitations
Short follow-up time.
Conclusion
Both interventions improved the clinical and some microbiologic characteristics, but there was no difference between both interventions. In addition, most ulcers showed indistinguishable genetic profiles of S. aureus and P. aeruginosa between T0 and T30, with no difference between the groups.
