Correlations between Psoriasis and Inflammatory Bowel Diseases

For a long time the relationship between inflammatory bowel diseases (IBDs) and psoriasis has been investigated by epidemiological studies. It is only starting from the 1990s that genetic and immunological aspects have been focused on. Psoriasis and IBD are strictly related inflammatory diseases. Skin and bowel represent, at the same time, barrier and connection between the inner and the outer sides of the body. The most important genetic correlations involve the chromosomal loci 6p22, 16q, 1p31, and 5q33 which map several genes involved in innate and adaptive immunity. The genetic background represents the substrate to the common immune processes involved in psoriasis and IBD. In the past, psoriasis and IBD were considered Th1-related disorders. Nowadays the role of new T cells populations has been highlighted. A key role is played by Th17 and T-regs cells as by the balance between these two cells types. New cytokines and T cells populations, as IL-17A, IL-22, and Th22 cells, could play an important pathogenetic role in psoriasis and IBD. The therapeutic overlaps further support the hypothesis of a common pathogenesis.

Mediterranean diet and familial dysmetabolism as factors influencing the development of acne

Aim: To investigate the effects of adherence to the Mediterranean diet and familial dysmetabolisms on acne development. Methods: A community-based case–control study was carried out in Italy enrolling cases as acneic outpatients of a dermatological ambulatory service and controls as clinically healthy acne-free subjects. Food consumption were evaluated with a validated food-frequency questionnaire, exploring the consumption of pasta, meat, cheese, fish, fruit, vegetables, and olive oil. Adherence to the traditional Mediterranean diet was assessed by a 10-point Mediterranean diet scale that incorporated the main characteristics of this diet. A logistic regression analysis estimated the variables who predicted the odds of being case, using those variables that at the univariate analysis yielded a p-value <0.25. Results are presented as odds ratio (OR) or adjusted OR (AOR). Results: The study included 93 cases (36.6% males, median age 17 years) and 200 controls (32% males, median age 16 years). The Mediterranean diet score ≥6 revealed a protective effect towards acne (crude OR 0.22, 95% CI 0.08–0.64). Logistic regression analysis showed that familial hypercholesterolaemia, diabetes, and hypertension are strong risk factors for acne (AOR 8.79, 95% CI 1.67–46.22; 3.32, 95% CI 1.27–8.63; and 2.73, 95% CI 1.07–6.96, respectively), while the Mediterranean diet represents a protective factor (score ≥6, AOR 0.31, 95% CI 0.11–0.89). Conclusions: The odds for familial dysmetabolisms was higher in cases than in controls, confirming their role in determining or maintaining acne. Moreover, this is the first study demonstrating a protective role of the Mediterranean diet in the pathogenesis of acne.

Acitretin in management of diffuse common warts: a case report

Warts are among the most commonly observed dermatological diseases, caused by human papilloma virus (HPV), usually HPV1‐2 subtypes; HPV4‐7 are rarely found and mostly related to professional exposure (butchers and dairy workers). Different therapeutical approaches are possible, depending on extension and severity of lesions. The present authors describe the case of 32‐year‐old Caucasian man, who came to our attention for the presence of numerous exophytic papules on the back of both hands and over periungual regions, which appeared about 6 months before. Histological examination confirmed the clinical suspicion of common warts (HPV4). The patient underwent therapy by acitretin for 12 weeks, obtaining during the 8th week of therapy complete resolution of skin lesions. The present authors present this case for the unusual local aggressiveness of viral warts in an immunocompetent patient successfully treated with acitetrin.

Isotretinoin for the treatment of squamous cell carcinoma arising on an epidermoid cyst.

A 63‐year‐old man showed multiple concentric erythemato‐nodular lesions of approximately 1.5–3 cm in diameter, located in the parietal and temporal region. The skin biopsy allowed histological diagnosis of infundibular epidermal cyst associated with chronic granulomatous flogosis; in one of these, a well‐differentiated squamous cell carcinoma arising from the cyst wall was found. The patient received isotretinoin at the daily dosage of 0.5 mg/kg/day for 5 months. During 1‐year follow‐up, laboratory tests, computed tomography scans, and control histology were all in the normal range, with a good improvement of the lesions. Epidermal cysts and squamous cell carcinoma are both commonly encountered in practice. However, the association of epidermal inclusion cysts and squamous cell carcinoma in the skin is very rare. In some cases, including the present one, more potent chemopreventive strategies, such as the use of systemic retinoids, must be considered. Systemic retinoids are the most heavily researched chemopreventive agents and have shown promise for multiple types of cancer, including bladder and head and neck carcinomas. We would like to recommend the possibility to administer retinoids in a squamous cell carcinoma, achieving very satisfactory results; in our case, a complete remission of malignant lesion and an improvement of epidermal cysts were made, without the development of side effects associated with retinoids.
