The tattooed population in Italy: a national survey on demography, characteristics and perception of health risks.

BACKGROUND: In recent years, Italy has seen a constant upward trend in the practice of tattooing. The Italian National Health Institute has conducted a national survey to determine the prevalence of tattooed people in Italy and to study related features of the phenomenon. AIM: Establish the prevalence and characteristics of the tattooed population and evaluate awareness of the risks associated with tattoos, which can contribute to consumer health protection. METHODS: Computer-assisted telephone interviews and computer-assisted web interviews were completed by a sample of the general population; 7608 people aged between 12 and 75+. RESULTS: The prevalence of tattooed people was 12.8% of the general population in Italy (95% CI: 12.05%-13.55%), equivalent to an estimated 6 900 000 tattooed individuals. Tattoos were more prevalent among women, at 13.8%, while tattooed men accounted for 11.8%. The vast majority of tattooed subjects had decorative tattoos of small dimensions, with a higher prevalence of monochromatic tattoos. Only a minority of tattooed participants reported having cosmetic tattoos (3.0%) or medical tattoos (0.5%). According to the data, 3.3% of tattooed subjects claimed complications or reactions; of these, only 21.3% consulted a dermatologist/general practitioner; more than half (51.3%) did not consult anyone. In general, only 58.2% of the sample were aware of health risks. The Italian survey showed that 36.7% of all tattoos had been performed in the last five years prior to the interview. CONCLUSIONS: The estimated prevalence of tattoos in Italy is in agreement with the statistics of the European Union. The prevalence in the age group 35-44 years is almost double that of the Italian population and it is higher in women than in men. Tattooing is relevant to public health. The high number of tattooed Italians, the potential long-term effects on health and the reported complications call for the awareness of health authorities. Appropriate intervention should ensure safer tattooing by reinforcing the training of tattooists, by improving surveillance and by providing information to raise public awareness of the risks and contraindications of tattooing.

Medical tattooing, the new frontiers: a case of nail bed treatment.

The primary objective of medical tattooing is to restore part of a patient's physical integrity. Moreover, the procedure seeks to assist in psychological recovery from the physical and/or psychological consequences of disease, surgery or trauma. The method described in this brief note marks a step forward in the field of such tattooing. The treatment simulates reconstruction of the nail bed, as the nails of the big toes had previously been removed through a surgical avulsion procedure. This treatment, agreed with the physician and performed by a tattooist with proven experience in medical tattooing, also involved the use of specific colour nuances that resulted in an extremely realistic outcome.

Simultaneous analysis of 17alpha-estradiol and 17beta-estradiol in bovine serum by liquid chromatography-tandem mass spectrometry.

A new LC-MS/MS method for the separation, identification and quantification of residues of 17alpha-estradiol (17alpha-E2) and 17beta-estradiol (17beta-E2) in bovine serum is reported. Deuterium-labelled 17beta-estradiol was used as internal standard. The method was in-house validated in accordance with European Union criteria and adopted in a proficiency study organised by the Community Reference Laboratory (CRL-RIVM, Bilthoven, The Netherlands). The analytes were extracted from serum using acetate buffer, purified by C18 solid-phase extraction (SPE) and chromatographed on a C18 LC column. They were then ionized in a heated nebulizer (HN) interface operating in negative ion mode, where only intact deprotonated molecules, [M-H](-), were generated at m/z 271 and 274 for 17alpha/17beta-E2 and 17beta-E2-d(3), respectively. The decision limits obtained (CCalpha, i.e., critical concentration alpha) were 0.06 ng/mL and 0.03 ng/mL, respectively for 17alpha-E2 and 17beta-E2. Detection capability (CCbeta, i.e., critical concentration beta) values were 0.08 ng/mL and 0.04 ng/mL, respectively, for 17alpha-E2 and 17beta-E2. Precision, accuracy and specificity were satisfactory, recovery ranged from 86.3% to 93.2% and the method resulted sensitive for the required purposes. This method is currently in use for Official Control purposes.
