Prevalence of cardiovascular pathologies in elderly population living in an industrialized area, compared to a control population residing in a rural area.

The development of cardiovascular pathologies is potentially connected to the surrounding environment, partly due to purely environmental factors, like exposition to pollutions, or anthropological ones, like the type of manual or stressing working activities. The relevant literature has already widely discussed the correlation between the acute and chronic exposition to atmospheric pollutants of different types and the pathogenetic events, such as the atherogenesis, thrombosis, and hypertension, The present study intends to verify this idea on a larger population exposed to different geographical conditions, comparing an agricultural village (Pachino-Siracusa) with an industrialized area (Augusta-Siracusa), both having identical sanitary services of basic importance. On the basis of the specific rates of hospitalizations, we compared the prevalence of cardiovasular pathologies in the resident populations. These studies confirmed the negative influence of the risk factors deriving from the environmental pollutions even on the cardiovascular aging, displaying an increased rate of hospitalization for angina pectoris, myocardial infarction and cardiac arrhytmias in the industrialized population.

Studies on health in elderly observation centers (abbreviated from Italian: COSA): a multidimensional evaluation (MDE) of an elderly population frequenting a diurnal center in Catania.

The worldwide progressive aging of the population forces us to reconsider the strategies of evaluation the effects of the geriatric "tsunami" on the health politics. The present study on the COSA (abbreviated from the Italian name: "Centro Osservazione Salute Anziani") has the aim to investigate the effects of a new form called Specialistic Geriatric Assistance on the already existing geriatric services in our territory, like UVG (Unità Valutazione Geriatrica), ADI (Assistenza Domiciliare Integrata), MMG (Medici di Medicina Generale). The present preliminary studies were carried out a group of elderly people frequenting the elderly day center "Villa Angela" located in Catania. We enrolled 42 subjects, 29 females and 13 males, in the age-range of 65-89 years (mean=73.6 years). An evaluation protocol was used for the participants, having two parts. The first part was a general one performing an accurate anamnestic examination, while the second part evaluated the cognitive and affective spheres, and the levels of autonomy and autosufficiency. The data obtained show that that the elderly population of the daily center "Villa Angela" in Catania is affected by numerous pathologies and comorbidities, which all increase the total risk of disabilities. The subjects use a high number of medicines (sometimes more than 10), which is not always justified by the pathologies found in them. Considering the functional profiles of the patients, the sanitary services offered to them are appropriate, because almost all of the elderly people were autonomous and autosufficient, having still adequate physical performances. The higher cognitive performance seemed to be reduced in more than 50% of the patients, showing almost always a slight or moderate deterioration. The depressive state measured by the GDS seemed to reach the deflection of joy of life 54.8%, while the established depression was detected in 12%. These results emphasize the importance of the functional psychogeriatric screening, which is able to reveal an early diagnosis of depression in the geriatric ages. For this, and many other motifs, we believe that these preliminary examinations suggest to organize at least one COSA available to our elderly people.

Effects of two estroprogestins containing ethynilestradiol 30 microg and drospirenone 3 mg and ethynilestradiol 30 microg and chlormadinone 2 mg on skin and hormonal hyperandrogenic manifestations.

Hyperandrogenic manifestation in women, such as seborrhea, acne and increased hair growth are common reasons of psychological distress. Skin appearance is very important for young women. This study evaluated the hormonal and skin effects of two estroprogestins (EPs) containing ethinyl-estradiol (EE) 30 microg associated with drospirenone (DRSP) 3 mg or chlormadinone acetate (CMA) 2 mg, respectively. Fifty-five women with signs and symptoms of hyperandrogenism (seborrhea, acne and increased hair growth) were enrolled in the study; randomly, 30 women were treated with EE 30 microg + DRSP 3 mg and 25 with EE 30 microg + CMA 2 mg. Follicle-stimulating hormone (FSH), luteinising hormone (LH), 17-hydroxyprogesterone (17OHP), androstenedione (A), testosterone (T), dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG) and free androgen index (T x 100/SHBG, FAI) were assessed at baseline, and after 3 and 6 months of treatment with EPs. Effects on seborrhea, acne and increased hair growth (as Ferriman-Gallwey score) were also evaluated at the same time points. Finally, skin hydration, transepidermal water loss (TEWL) and skin homogeneity were studied with non-invasive technique during the study. Treatment for 6 months with both EPs decreased significantly the circulating androgen levels (A, T, DHEAS) and FAI, and increased SHBG levels; also skin pattern was improved. EP containing EE and DRSP was better than EP containing EE and CMA as for skin changes, as seborrhea, acne, increased hair, hydration, homogeneity and overall quality of the skin; moreover, hormonal changes (as FAI) under therapy were more pronounced with EE/DRSP than EE/CMA. These effects may be considered in EP choice and could be important in improving patient's compliance and quality of life in hyperandrogenic women.

Clinical and instrumental evaluation of skin improvement after treatment with a new 50% pyruvic acid peel.

BACKGROUND: Pyruvic acid is an alpha-keto acid that presents keratolytic, antimicrobial, and sebostatic properties as well as the ability to stimulate new collagen production and elastic fibers formation. Because of its low pKa and its small dimension, it penetrates rapidly and deeply through the skin, so far as to be considered a potent chemical peel agent. It has proven its efficacy for the treatment of many dermatological conditions such as acne, superficial scarring, photodamage, and pigmentary disorders. Pyruvic acid application usually induces intense burning, and the postpeeling period is characterized by erythema, desquamation, and, sometimes, crusting. OBJECTIVE: The aim of the study is to assess the efficacy and tolerability of 50% pyruvic acid in a new non-erythematogenic formulation (pyruvic acid 50%, dimethyl isosorbide, propylene glycol, ethyl alcohol, dimethyl sulfone, ethyl lactate, water) for the treatment of photodamage, superficial scarring, and melasma. MATERIALS AND METHODS: Twenty subjects affected by photodamage, superficial scarring, and melasma, but otherwise healthy, entered the study. Four peeling sessions were performed once every 2 weeks. The patients were evaluated clinically and by means of several noninvasive methods in order to monitor the following parameters: hydration, color (erythema and pigmentation), elasticity, skin smoothness, skin roughness, scaliness, and wrinkles. RESULTS: The patients did not report any discomfort either during the peeling session or during the postpeeling period, without any impact on their social life. We did not observe any case of persistent erythema as well as any case of postinflammatory hyperpigmentation. Instrumental evaluations showed a significant reduction in the degree of pigmentation in patients with melasma, a significant increase in skin elasticity, and an improvement of the degree of wrinkling in all the patients. CONCLUSION: This innovative formulation of 50% pyruvic acid peel has been shown to be safe and effective to treat photodamage, melasma, and superficial scarring, allowing the patients to carry out regularly their working life as well as their social life. Furthermore, the results have been evaluated by means of noninvasive devices, which have permitted one to quantify the improvements.

Erbium:YAG laser and cultured epidermis in the surgical therapy of stable vitiligo.

OBJECTIVE: To induce complete and reproducible repigmentation of large "stable" vitiligo lesions by means of autologous cultured epidermal grafts using a rapid, simple, and minimally invasive surgical procedure. DESIGN: Achromic epidermis was removed by means of appropriately settled erbium:YAG laser, and autologous epidermal grafts were applied onto the recipient bed. Melanocyte content was evaluated by dopa reaction. The percentage of repigmentation was calculated using a semiautomatic image analysis system. SETTING: A biosafety level 3-type cell culture facility, a surgical ambulatory department, and a dermatological department in a hospital. PATIENTS: Twenty-one patients with different types of vitiligo were admitted to the study and treated with autologous cultured epidermal grafts. Inclusion criteria were failure of at least 2 standard medical approaches; no therapy for at least 12 months; no progression of old lesions or appearance of new lesions; no Koebner phenomenon within the past 18 months; and no autoimmune disorders. RESULTS: The average percentage of repigmentation in 21 patients was 75.9% (1759.7 cm2 repigmented/2315.8 cm2 transplanted). Three patients showed a reactivation of their vitiligo and did not show repigmentation. The remaining 18 patients, with 43 distinct lesions, showed an average percentage of repigmentation of 90% (1759.7 cm2 repigmented/1953.4 cm2 transplanted). CONCLUSIONS: Under appropriate conditions, cultured epidermal grafts induce complete repigmentation of stable vitiligo lesions. Erbium:YAG laser surgery can supply a fast and precise tool for disepithelialization, hence allowing treatment of large vitiligo lesions during a single surgical operation.

Evidence for the association of human papillomavirus infection and cutaneous squamous cell carcinoma in immunocompetent individuals.

OBJECTIVE: The aim of our study was to evaluate human papillomavirus (HPV) infection as a risk factor for cutaneous squamous cell carcinoma (SCC) in immunocompetent individuals. DESIGN: Hospital-based case-control study. SETTING: Referral center for dermatologic diseases for central and southern Italy. PARTICIPANTS: Consecutive patients with histologically confirmed cutaneous SCC (n = 46) and control subjects (n = 84) chosen by frequency matching (age and sex) among patients admitted with unrelated diseases. MAIN OUTCOME MEASURE: Infection with epidermodysplasia verruciformis-related HPV types, blindly assessed by serologic testing (viruslike particle enzyme-linked immunosorbent assay). Information was obtained on known potentially confounding risk factors (family history, history and signs of sun exposure, and pigmentary traits) and on history of HPV-related lesions and diseases, assessed by interview and examination by a dermatologist. RESULTS: Positive serologic findings for HPV type 8 were associated with SCC (odds ratio, 3.2; 95% confidence interval, 1.3-7.9) independently of other risk factors, whereas positive serologic findings for HPV type 15 were negatively associated with SCC (odds ratio, 0.4; 95% confidence interval, 0.2-0.9). Other variables significantly associated with the tumor were family history of skin cancer, professional or recreational sun exposure, light eye color, high number of solar keratoses and seborrheic keratoses on the body surface, and residency in radon-emitting buildings. CONCLUSIONS: Positive serologic findings for HPV type 8 are associated with SCC occurrence in immunocompetent individuals. Viral infection could act as a cofactor in the tumor development, along with genetic predisposition, solar radiation, and other environmental exposures. If confirmed, these findings could open new perspectives for treatment and prevention of SCC.
