Prolidase deficiency in two dermatological patients in western Sicily.

Prolidase deficiency is a rare disorder inherited through an autosomal recessive gene. The hallmark of the disorder are iminodipeptiduria, chronic skin ulcers, recurring infections, mental retardation and characteristic facial appearance, although prolidase deficiency can occur with no clinical manifestation. The primary biological function of the enzyme involves the metabolism of collagen degradation products and the recycling of proline for collagen resynthesis.

Timing of quality of life improvements in psoriatic patients treated with different systemic therapies.

Psoriasis impacts the quality of life (QoL) by disrupting overall health and social life. Thus, the use of a QoL evaluation item is crucial in assessing a therapeutic regimen. Also, faster improvements in QoL lead to better patient compliance, but very few studies compare psoriasis traditional and biologic therapies timing.

A Case of Moderate Hidradenitis Suppurativa and Psoriasis Treated with Secukinumab.

Hidradenitis suppurativa (HS) is a disorder of the apocrine gland causing a chronic, recurrent and painful inflammation. It is a disabilitating condition and, though many therapeutic options are available, the response is often ineffective in most cases and patients can present many recurrences with physical and psychological sequelae. Recent data had shown increased interleukin (IL)-17 serum levels in patients with HS.

Gender differences in adverse drug reactions in dermatological patients in west Sicily: an epidemiological study.

Purpose: The purpose of this study was to show that gender also plays an important role in pharmacokinetics, pharmacodynamics, and drug toxicity. It is only fair to take into account the so-called "gender-based medicine."

Methods: We again selected admission for cutaneous adverse drug reaction (CADRs), from January 2012 to July 2012, in order to detect and verify, in an analytical way, the substantial gender differences in adverse drug reactions in term incidence, clinical manifestations, severity and drugs involved.

Refractory acne and 21-hydroxylase deficiency in a selected group of female patients.

Background: Excessive androgen production, suspected in women when acne is accompanied by hirsutism and menstrual irregularities, may be due to congenital adrenal hyperplasia. This inherited disorder of cortisol biosynthesis is caused in more than 90-95% of all cases by 21-hydroxylase deficiency (21-OHD). The steroid 21-hydroxylase gene (CYP21) has a high degree of variability.
