Resveratrol (3,4’,5-trihydroxy-trans-stilbene) is a natural phytoalexin found in grapes and wine, which has been extensively studied for a wide range of biological effects. A large number of stilbene-containing derivatives have displayed antioxidant and antiproliferative activities on various cancer cell lines. In this study, a series of stilbene hybrids 1-9, previously reported as peroxisome proliferator-activated receptor (PPAR) agonists, were assessed at micromolar concentrations using MTT cell viability assay in C2C12 and MCF7 cell lines...

Fibroblast growth factor 21 (FGF21) is known as a major metabolic regulator of glucose and lipid homeostasis. Continuous intracerebroventricular (i.c.v.) administration of FGF21 was found to modulate feeding and energy expenditure in rats with diet-induced obesity, suggesting a central effect by the peptide. In this context, in the present work, we studied the effects of a single central FGF21 administration (0.5-5 µg) on feeding and energy expenditure by evaluating locomotor activity, interscapular brown adipose tissue (BAT) weight, gene expression of uncoupling protein-1 (UCP-1) in BAT and plasma norepinephrine (NE) levels in Sprague-Dawley fed rats...

Atopic dermatitis (AD) leads to severe psychosocial disturbances that are quite frequently underestimated. We evaluate the quality of life (QoL) of adult patients with AD and their family members using DLQI, B-IPQ, FDLQI questionnaires, observe psychopathological features with CAQ II questionnaire and evaluate correlations between QoL, psychological disturbances and objective/subjective parameters of disease severity. A reduction in QoL has been proven by all questionnaires with statistically significant relationships between all of them...

Prevalence of chronic venous leg ulcers has increased from 55% to 75% in 10 years. We treat chronic vascular lesions according to a cyclic multiphase method that follows the instrumental and differential etiologic diagnosis of ulcers of the lower limbs. The AIMED (Anti Inflammatory Regenerative Medicine) operating model follows the diagnostic phase and is structured in 5 interconnected phases. Mare evaluation, pH control, biofilm removal and prevention and infections are approached according to the International Guidelines...

Despite the new World Health Organization data remind us how syphilis is a disease which affects both sexes equally, this pathology has always been mainly considered a male disease. While several famous men are known to be affected by syphilis, there are very few women affected by this pathology of which we have historical records. Through the lives of Mary Todd Lincoln, Catherine of Aragon, Karen Blixen and Florence Foster Jenkins, this article would like to grant dignity to all the women who contracted syphilis in the wrong historical era where, for a woman, admitting to contracting it was shameful...

Throughout the centuries, the undefended nature of man has very often manifested in cases of epidemics, which have determined scenarios of suffering and death. Through “historical” observation lens, it is possible to understand the relationship between the spread of viruses, bacteria and parasites responsible for these epidemics and the displacement of ancient or contemporary travellers. We have analysed two infective diseases, syphilis and SARS, and their role in history and in medicine.

Aesthetic surgery of female external genitalia has gained increasing popularity over the past decade, with reduction of the labia minora (labiaplasty) being the procedure most commonly requested and performed. Female external genitalia lose elasticity and volume with age, but few studies describe the techniques for labia majora augmentation. Currently, very few studies have investigated the effectiveness and safety of labia majora augmentation with hyaluronic acid (HA) injection. This study aims to evaluate the effectiveness and safety of labia majora augmentation with hyaluronic acid filler injection...

A good aesthetic result in thyroid surgery is one of the main goals, as this procedure usually involves young women affected in clearly visible anatomical areas. To minimize the detrimental effects of scarring outcome, several therapeutic options have been employed. Lasers may be an alternative choice for prevention and treatment of post-surgical thyroidectomy scar. This paper reviews literature and the current knowledge on this topic. A comprehensive search in the Cochrane Library, MEDLINE and PUBMED databases was performed to identify relevant literature investigating the role of laser therapy in both prevention and treatment of unappealing scarring after thyroid surgery...

Neauvia Stimulate® is a biocompatible, injectable hyaluronic acid (HA) filler (26 mg/ml) PEG cross-linked with 1% of calcium hydroxyapatite (CaHA) for facial soft-tissue augmentation that provides volume to tissues, followed by a process of neocollagenesis for improving skin quality. The aim of the present study is to evaluate the possible modulation of collagen synthesis after treating human fibroblasts cultured in vitro with the product (Lot. 160517-26-1/2 PEG). The experimental model proposed, despite being an in vitro system, allows the derivation of useful information to predict the possible activity of the product in further in vivo application...

In this study, microscopic, histochemical and ultrastructural observations in human skin are presented, 8 months after an injection of a novel PEGylated filler. Morphological features demonstrated an excellent integration of the filler with the connective tissue components and an effective interpenetration with the ground substance. The filler appears uniformly distributed inside the hypodermis. No segregation or encapsulation of cells and other structures was observed nor evidence of immunological adverse reaction...

An 88-year-old Caucasian man recently sought medical attention due to recrudescence of skin disease in the area of previously excised nodule (in 2002) on the nose dorsum. The original lesion was clinically considered as a pigmented basal cell carcinoma, after which histological examination revealed a superficial spreading melanoma in vertical growth face (Clark level IV; Breslow thickness 2.1 mm) arising from a pre-existing nevus. The adjacent skin also showed significant actinic damage both in the epidermis and in the dermis...

Stigmata are one of the most ancient and fascinating mysteries of the Christian religion. The word “stigmata” derives by the Greek “stigma”, that means sign, mark. Classically, stigmata are the sores inflicted on Jesus Christ during his passion and crucifixion. Today, the term stigmatized has been extended to designate several cases of individuals, who show skin sores similar to those of Christ. The Authors report a brief history of stigmata, trying to give an explanation to such a fascinating phenomenon...

Since its first description by Duncan, Tschen and Knox in 1987 in the former Archives of Dermatology (1), “Terra firma-forme dermatosis” has been variously described in medical literature, representing a strange, probably underestimated, cutaneous disease. During the last 40 years, the condition has been recorded as an undesirable as well as unexplained event, occurring mainly in childhood, characterized by a brownish-black appearance of the whole skin, resembling dirt. Recently, authors described several cases of atypical patterns of the disease, sometimes with impressing topographic clinical pictures, evocative for syndromic phenotypes...

Neotrombicula autumnalis is an arthropod living in the soil and parasitizes animals only in its larval stage. Depending on climatic conditions, one to five life cycles can take place in a single year. Human infestation is probably underestimated and can be easily missed due to non-pathognomonic cutaneous manifestations in absence of systemic signs. We describe a case of human trombiculiasis and discuss the diagnostic and therapeutic management of this ‘synanthropic’ dermatosis.

Glomerular filtration rate (GFR) has been shown to be lower than physiological values during exercise with a strong negative correlation with exercise intensity. Among new markers of renal function, neutrophil gelatinase-associated lipocalin (NGAL) seems to be very promising. It is an early, sensitive and specific marker of acute kidney injury (AKI) with two isoforms: plasma NGAL (pNGAL) and urinary NGAL (uNGAL). The aim of the present study was to assess acute variations in NGAL plasma levels after performing high endurance physical exercise in a group of professional cyclists during the two major European professional cycling competitions (Giro D’Italia and Tour de France)...

Vitamin D may have prognostic value in cardiovascular disease (CVD) patients and, in addition to conventional biomarkers, could be a valuable tool for disease management. The aim of this study was to assess the association of vitamin D status in patients with acute coronary syndrome (ACS) and to evaluate its prognostic utility. The levels of 25(OH) vitamin D were correlated with troponin T hs. Forty-eight consecutive outpatients (40 Caucasian and 8 Asian) aged between 40 and 70 years (mean 61.5, range 43-77 years) were enrolled in the study...
