The case of a 24‐year‐old male patient affected by follicular occlusion tetrad (acne conglobata, hidradenitis suppurativa, pilonidal cyst and dissecting cellulitis of the scalp) associated with clinical signs of pachyonychia congenita (PC)‐2 (focal palmoplantar keratoderma, plantar pain, onycodystrophy and multiple cysts) is reported. The diagnosis was supported by genetic analysis that showed heterozygous mutation within the exon 1 of KRT17 gene. This case may reflect different expressions of a phenotypic spectrum induced by a common genetic alteration. [ABSTRACT FROM AUTHOR]

The article discusses research involving adult patients with erythematous-desquamative dermatitis to assess the prevalence of bushy capillaries in lesional skin. Topics covered include the findings of the analysis of psoriatic plaques, bushy capillary microvascular pattern in psoriasis versus atopic dermatitis and contact dermatitis and the evaluation of the vascular pattern by videodermatoscopy (VD).

Background: Hidradenitis suppurativa (HS) is a chronic, relapsing, inflammatory skin disease characterized by painful inflamed nodules, recurrent abscesses and fistulas located in apocrine gland–bearing body sites. The negative impact of HS on patient's quality of life (QoL) has been reported to be greater than other dermatologic conditions as psoriasis and atopic eczema, and its improvement is an important goal in disease management. Nowadays, there are no specific validated QoL instruments available for HS and generic dermatologic questionnaires are used. Objective: The objective of this study was to demonstrate the validity, reliability and responsiveness of HIDRAdisk, a new innovative tool designed for rapid assessment of HS burden and, at the same time, an intuitive graphic visualization of the measurement outcome. Methods: A multicentre, longitudinal, observational study was conducted to validate the HIDRAdisk compared with other validated questionnaires [Skindex‐16, Dermatology Life Quality Index (DLQI), Work Productivity and Activity Impairment–General Health (WPAI:GH)] and to evaluate its correlation with disease severity in Italian patients with any degree of HS severity, as measured by Hurley stage and HS Physician Global Assessment (HS‐PGA). Results: A total of 140 patients (59% women; mean age 34.9 ± 11.0 years) were enrolled in 27 dermatologic centres. HIDRAdisk showed a strong correlation with Skindex‐16 and DLQI, and a good one with WPAI:GH (correlation coefficient: 0.7568, 0.6651 and 0.5947, respectively) and a statistically significant correlation with both Hurley stage and HS‐PGA. Very good internal consistency (Cronbach coefficient >0.80; intraclass correlation coefficient >0.6), with correlation between the 10 items, good test–retest reliability (Spearman correlation coefficient, 0.8331; P < 0.0001) and responsiveness to changes were demonstrated. Conclusion: Our study shows that HIDRAdisk, a short and innovative visual HS QoL instrument, has been psychometrically validated in Italian language and it may help improve the management of HS once implemented in routine clinical practice.

The article offers information on the comparison of clinical and ultrasound scores in patients with hidradenitis suppurativa (HS). Topics discussed include information on the use of the ultrasound techniques for diagnosis and assessment of HS disease severity; discussions on the using sonographic scoring system for HS; and the information on the clinical assessment for the complementary tests.

Background: Different lifestyle and dietetic factors have been linked with the onset and severity of acne. Objective: To assess the complex interconnection between dietetic variables and acne. Methods: This was a reanalysis of data from a case-control study by using a semantic connectivity map approach. 563 subjects, aged 10-24 years, involved in a case-control study of acne between March 2009 and February 2010, were considered in this study. The analysis evaluated the link between a moderate to severe acne and anthropometric variables, family history and dietetic factors. Analyses were conducted by relying on an artificial adaptive system, the Auto Semantic Connectivity Map (AutoCM). Results: The AutoCM map showed that moderate-severe acne was closely associated with family history of acne in first degree relatives, obesity (BMI ≥ 30), and high consumption of milk, in particular skim milk, cheese/yogurt, sweets/ cakes, chocolate, and a low consumption of fish, and limited intake of fruits/vegetables. Conclusion: Our analyses confirm the link between several dietetic items and acne. When providing care, dermatologists should also be aware of the complex interconnection between dietetic factors and acne. [ABSTRACT FROM AUTHOR]

Background The last decades have witnessed an increasing interest for the psychosocial aspects of chronic skin diseases, such as psoriasis. Nonetheless, systematic assessments of the impact of psoriasis on patients' lives are rarely done in daily clinical practice. The existing instruments are mostly meant to be completed by patients alone, and rarely comprise a graphical representation of the results. Objective To develop a questionnaire allowing both a quick assessment of the impact of psoriasis on patients and, at the same time, an intuitive graphic visualization of the outcome of the test. Methods A preliminary version of an Italian questionnaire aimed to assess the global impact of psoriasis on patients, meant to be filled in together by the patient and the dermatologist and to produce visual, intuitive results, was developed through focus groups. The instrument was then the object of a Delphi survey addressed to a panel of experts, to assess both the need of possible improvements of the questionnaire (in terms of the formulations of the questions and of the domains to be explored) and the usefulness of the questionnaire. Results A 10-item questionnaire in Italian, taking into account different aspects of the burden of psoriasis on the patient, was developed. The answers are given on a 10-point visual analogue scale and graphically represented on a disc as a polygon. Conclusions A formal validation of the questionnaire and a study to assess potential clinical and psychological benefits of a systematic implementation of the instrument in daily practice are planned.
