The Fas/Fas ligand system triggers the extrinsic apoptotic pathway and is involved in several inflammatory conditions, also at the skin level. The Fas/Fas ligand cell death pathway plays a major role in anoikis, a type of apoptosis characterized by cell detachment. As pemphigus is characterized by loss of cell to cell adhesion, we evaluated the role of(More)
BACKGROUND Survivin is detected in few adult normal cells and it is highly expressed in cancer. Nuclear survivin facilitates cell cycle entry, whereas the mitochondrial pool protects cells from apoptosis. Survivin is overexpressed in keratinocyte stem cells (KSCs) and protects them from apoptosis. METHODS As KSCs are at the origin of squamous cell(More)
In human epidermis, keratinocyte stem cells (KSC) are characterized by high levels of β1-integrin, resulting in the rapid adhesion to type IV collagen. Since epithelial tumors originate from KSC, we evaluated the features of rapidly adhering (RAD) keratinocytes derived from primary human squamous cell carcinoma of the skin (cSCC). RAD cells expressed higher(More)
BACKGROUND A non-steroidal, anti-inflammatory moisturizing cream containing rhamnosoft, ceramides, and L-isoleucine (ILE) (pro-AMP cream) has been recently developed for the specific treatment of atopic eczema (AE) of the face. In this trial, we evaluated the clinical efficacy and tolerability of pro-AMP cream in the treatment of facial AE in children in(More)
Squamous Cell Carcinoma-derived Stem-like Cells (SCC-SC) originate from alterations in keratinocyte stem cells (KSC) gene expression and sustain tumor development, invasion and recurrence. Since survivin, a KSC marker, is highly expressed in SCC-SC, we evaluate its role in SCC-SC cell growth and SCC models. Survivin silencing by siRNA decreases clonal(More)
Eryfotona AK-NMSC (ISDIN Spain) is a film-forming medical device in cream or fluid formulation containing the DNA-repair enzyme photolyase and high-protection UV filters in liposomes (repairsomes) indicated in the treatment of cancerization field in patients with actinic keratosis (AK) or non-melanoma skin cancer (NMSC). Photolyase is an enzyme that(More)
INTRODUCTION Sunscreen protection in subjects with actinic keratosis (AK) is highly recommended to prevent clinical evolution of this in situ skin cancer condition. Use of topical anti-cyclooxygenase drugs such as diclofenac and piroxicam reduces the number of lesions and improves the cancerization field. A film-forming medical device in a cream formulation(More)
In order to investigate the value of MRI in the staging of renal cell carcinoma and to compare the results of MRI and CT, the authors evaluated by means of MRI and CT 42 patients affected with renal cell carcinoma. All patients underwent surgery, and pathology of the surgical specimens was performed. A comparison was made between the surgical and pathologic(More)
Atopic eczema (AE) is a skin disease very common in paediatric population and face region is commonly involved. AE of the face represents a therapeutic challenge limiting the use, especially for long periods, of corticosteroid topical products due to the high risk of atrophic skin changes. Skin barrier alterations and reduction of innate immune mechanisms(More)
AIM Treatment of plantar and periungueal warts (so called "difficult-to-treat" warts, DTW) and external genital warts (EGW) remains unsatisfactory. Medical or invasive procedures are partially effective and/or painful. Furthermore recurrences rates after treatments are still a relevant problem for all the available therapies. Nitric-zinc complex is a(More)
