Background: Eyelashes have both a protective and an aesthetic function. Hypotrichosis of the eyelashes may negatively influence an individual's self-perception., Objective: To evaluate efficacy and safety of topical administration of a new cosmetic preparation containing 15 keto fluprostenol isopropyl ester (80 µgr/mL) for the treatment of idiopathic hypotrichosis of the eyelashes., Methods: This is a monocentric, double-blind, vehicle-controlled study. Forty patients (18 years) with idiopathic hypotrichosis (GEA 1 or 2), who also exhibit feelings of low confidence, based on the ESQ score, were divided into two groups. Group 1: twenty women treated with once-daily 15 keto fluprostenol isopropyl ester gel and Group 2: twenty women treated only with the vehicle gel., Results: Group 1: The average difference in eyelash length measured at the midpoint of palpebral margins between T0 and T2 for Group 1 was 1633 mm and for Group B was 0.25 (P < 0.0001). Comparing the ESQ questionnaires of Groups 1 and 2 from T0 to T2, only the 80% of the patients of Group 1 declared to dedicate less time to the application of cosmetic mascara, having longer and darker lashes at T2 vs patients of Group 2, of which only 20% reported longer and darker eyelashes at T2. About safety, only one patient of Group 1 experienced sensation of ocular sensation heaviness and headache. No other side effects were referred., Conclusions: 15 keto fluprostenol isopropyl ester gel was effective in enhancing eyelash growth, with an excellent safety profile., (© 2019 Wiley Periodicals, Inc.)

This review focuses on recent evidences about human microbiome composition and functions, exploring the potential implication of its impairment in some diffuse and invalidating inflammatory skin diseases, such as atopic dermatitis, psoriasis, hidradenitis suppurativa and acne. We analysed current scientific literature, focusing on the current evidences about gut and skin microbiome composition and the complex dialogue between microbes and the host. Finally, we examined the consequences of this dialogue for health and skin diseases. This review highlights how human microbes interact with different anatomic niches modifying the state of immune activation, skin barrier status, microbe-host and microbe-microbe interactions. It also shows as most of the factors affecting gut and skin microorganisms' activity have demonstrated to be effective also in modulating chronic inflammatory skin diseases. More and more evidences demonstrate that human microbiome plays a key role in human health and diseases. It is to be expected that these new insights will translate into diagnostic, therapeutic and preventive measures in the context of personalized/precision medicine.

Female pattern hair loss (FPHL) is the most common form of alopecia in women. Affected women may experience psychological distress and impaired social functioning. Early diagnosis and initiation of treatment are desirable because treatments are more effective to avoid the progression of hair loss than stimulating regrowth. Typically, a diagnosis of FPHL can be confirmed by review of a patient's medical history and a physical examination alone. Testing a scalp biopsy is diagnostic but usually not required. In women with signs of hyperandrogenism, an investigation for ovarian or adrenal disorders should be performed. Treatment for FPHL is obscured by myths. The aim of FPHL treatment could be two-fold: Reverse or stabilize the process of hair follicle miniaturization. Mild-to-moderate FPHL in women can be treated with oral antiandrogen therapies (cyproterone acetate and spironolactone) and/or topical minoxidil with good results in many cases. If used correctly, available medical treatments arrest the progression of the disease and reverse miniaturization in most patients with mild-to-moderate FPHL. Hair systems and surgery may be considered for selected cases of severe FPHL.

Aim: Hidradenitis suppurativa (HS) is a chronic inflammatory disease, commonly characterized by painful, deep dermal abscesses and chronic draining sinus tracts. Recently, laser and light-based therapies have become more commonly used in the management of HS., Material and Methods: We report 20 HS patients treated with a 1064 nm wavelength, emitted from a diode laser, launched in an optical fibre through intracavitary modalities., Results: Each patient underwent four laser sessions, one every two weeks. we recorded a significative reduction (31%) of Sartorius score from 28.55 ± 13.04 to 19.75 ± 12.29 after 4 laser sessions (p < 0.05). No one has had a worsening of the disease., Conclusion: Intralesional diode laser 1064 nm can be a good treatment option for patients with moderate and localized hidradenitis suppurativa, because it is minimally invasive, doesn't have significant complications and provides a rapid post-treatment recovery.

Aim: Estimates of malignant melanoma (MM) incidence and prognosis vary widely. The present study was performed to analyze epidemiologic and prognostic aspects of primary MM mainly in relation to tumor thickness., Methods: We conducted a retrospective study on a cohort of 435 patients with diagnosis of primary MM between 1997 and 2011., Results: In the period 2009-2011, among the MM diagnosed 50.00% were thin, 32.43% in situ and 17.57% thicker while in 1997-1999 MM>1 mm accounted for 51.61% of diagnoses. Mean age of patients affected with thin MM was significantly lower than that of patients with MM>1 mm, and mean thickness resulted significantly lower in female patients than in males. Mean thickness of MM located on easily self-evaluable body areas was significantly lower than in those not accessible for skin self-examination. The commonest histogenetic type was superficially spreading melanoma. Mitotic rate, ulceration and vertical growth phase all resulted related to MM thickness. Out of 61 patients with thin MM who underwent SLNB, 3 resulted positive (4.92%): neither thickness >0.75 mm, nor ulceration, mitotic rate or Clark level were found to be associated with SLNB positivity. Five-year survival rate was 98.3% for thin MM patients and 76.4% for thick MM patients., Conclusion: Our trend analysis evidences a continuing increase of thinner primary MM throughout the study period, potentially enhancing patient prognosis. Regular skin self-examination could contribute to earlier recognition of MM. Identification of more powerful predictors of thin MM prognosis is necessary.
