    ABSTRACT: OBJECTIVE: The worldwide incidence of cutaneous malignant melanoma (MM) has been rising steadily over the past 30 years. At the same time non-melanoma skin cancers (NMSC) are the most prevalent type of cancer in United States and Europe. Up to date, no paper has explored the influence on the general survival in patients with MM and NMSC. We decided to perform a study with the aim to evaluate the different survival in patients with MM-NMSC compared to control patients (MM-CTRL). PATIENTS AND METHODS: To evaluate prognosis in both groups, we analyzed disease-free survival (DFS) and overall survival (OS).Kaplan-Meier product was performed for the survival analysis. Median DFS was 73 months in group and 72 months in MM-CTRL patients (p = 0.4); while, median OS was 74.2 months in MM-NMSC patients and 63.1 in MM-CTRL (p < 0.001). Also at Odds-Ratio (OR), the statistical significance was maintained (p < 0.007) with a better prognostic value for MM-NMSC. RESULTS: Among group patients, the ones with a basal cell carcinoma showed a batter behavior, than the ones with squamous cell carcinoma (p = 0.01). CONCLUSIONS: Patients with MM-NMSC showed a better survival than MM-CTRL patients (p < 0.001). The causes of this improved survival are still unknown; probably the endogenous immune response can play a pivotal role in this class of patients. However, further studies are necessary to better understand this phenomenon, not yet explored in literature.

    ABSTRACT: Ink spot lentigo, also known as reticulated black solar lentigo, is a melanotic macula commonly described in fair-skinned individuals on sun-exposed areas of the body. Clinically it is a darkly pigmented type of solar lentigo; herein the term ink spot lentigo. In contrast to common solar lentigines, ink spot lentigo is reported as a unique lesion. However usually ink spot lentigo appears among several common solar lentigines. We report a series of 5 patients who presented ink spot lentigo with typical dermoscopic pattern but singular clinical features.

    ABSTRACT: Frontal fibrosing alopecia (FFA) and lichen planopilaris (LPP) are classified as scarring alopecia. Most authors consider FFA as a clinical variant of LPP on the basis of their similar histological findings; other authors think these pathologies are two different entities. We studied 48 cases of FFA and 86 cases of LPP. Clinical diagnosis was histologically confirmed and all patients underwent videodermoscopy. Moreover, histological study, identifying the main targets of these diseases, results helpful to confirm the diagnosis. FFA selectively affects vellus-like hair in the frontoparietal region and is characterized by a mild skin atrophy and a total loss of follicular openings. In LPP an involvement of total preterminal, terminal and vellus-like follicles, partial or total loss of follicular openings, diffuse hair thinning and twisting, perifollicular erythematous or violaceous papules and mild/severe spinous follicular hyperkeratosis with scalp sclerosis are the features observed. Videodermoscopy improves diagnostic capability, appearing to be helpful to underline FFA and LPP features, confirmed by histologic studies which identify and show different intensity of inflammatory process. Therefore, the two diseases could be considered two different entities on the basis of the different clinical features and the different targets, that can be related to a different pathogenetic mechanism.

    ABSTRACT: Alopecia areata (AA) has been represented as a restricted T cell-mediated autoimmune disease. Several studies have shown that cytokines may play an important role in its pathogenesis although many pathways exist. We investigated cytokine (IL-2, IL-6, IL-12 and TNFalpha) levels in peripheral blood mononuclear cell (PBMC) of 105 patients with different grade and duration of alopecia areata, to confirm that T-cell responses in AA is regulated via mechanisms of peripheral T-cell tolerance. We observed that IL-12 levels are higher for patients with bigger extensions and tend to increase according to the duration of the AA; TNFalpha, instead, is more related to the gender of the patients and to the duration. Therefore abnormalities in cytokines production, showed by our results, may suggest that T-cell responses in AA scalp are closely regulated via mechanisms of peripheral T-cell tolerance and therefore confirm that this disease has an immuno-pathogenesis. Our aim is to shed light upon the complexity of AA underlying mechanisms and indicate pathways that may suggest future treatments.

    ABSTRACT: Minoxidil, a vasodilator medication known for its ability to slow or stop hair loss and promote hair regrowth, was first introduced, exclusively as an oral drug, to treat high blood pressure. It was however discovered to have the important side-effect of increasing growth or darkening of fine body hairs; this led to the development of a topical formulation as a 2% concentration solution for the treatment of female androgenic alopecia or 5% for treating male androgenic alopecia. Measurable changes disappear within months after discontinuation of treatment. The mechanism by which it promotes hair growth is not fully understood. Minoxidil is a potassium channel opener, causing hyperpolarization of cell membranes and it is also a vasodilator, it is speculated that, by widening blood vessels and opening potassium channels, it allows more oxygen, blood and nutrients to the follicle. This can also cause follicles in the telogen phase to shed, usually soon to be replaced by new, thicker hairs in a new anagen phase. It needs to be applied regularly, once or twice daily, for hair gained to be maintained, and side effects are common. The most common adverse reactions of the topical formulation are limited to irritant and allergic contact dermatitis on the scalp. There have been cases of allergic reactions to the nonactive ingredient propylene glycol, which is found in some topical solution especially if they are galenic. Increased hair loss which can occur during Minoxidil use, is due to the synchronization of the hair cycle that the treatment induces. In this review, we described its mechanism of action, use in dermatology and some patents related to alternative treatment of allergic reactions due to its use.

    ABSTRACT: The objective of this open label study is to determine the effectiveness of Serenoa repens in treating male androgenetic alopecia (AGA), by comparing its results with finasteride. For this purpose, we enrolled 100 male patients with clinically diagnosed mild to moderate AGA. One group received Serenoa repens 320 mg every day for 24 months, while the other received finasteride 1 mg every day for the same period. In order to assess the efficacy of the treatments, a score index based on the comparison of the global photos taken at the beginning (T0) and at the end (T24) of the treatment, was used. The results showed that only 38% of patients treated with Serenoa repens had an increase in hair growth, while 68% of those treated with finasteride noted an improvement. Moreover finasteride was more effective for more than half of the patients (33 of 50, i.e. 66%), with level II and III alopecia. We can summarize our results by observing that Serenoa repens could lead to an improvement of androgenetic alopecia, while finasteride confirmed its efficacy. We also clinically observed, that finasteride acts in both the front area and the vertex, while Serenoa repens prevalently in the vertex. Obviously other studies will be necessary to clarify the mechanisms that cause the different responses of these two treatments.

    ABSTRACT: In literature many different therapies are proposed to treat Monilethrix, but a definitive therapy still doe not exist. We decided to treat four patients affected by Monilethrix, with topical minoxidil 2%, 1 ml night and day for 1 year. Minoxidil led to a an increase of normal hair shaft without any side effects in all the patients. Therefore topical minoxidil 2% could be considered a good therapy to treat Monilethrix.
