Vito, 1, Rome 00168, ItalyEmail eleonora.nucera@policlinicogemelli.itAbstract: Allergy to natural rubber latex (NRLA) from Hevea brasiliensis is a relevant public health issue, in particular in healthcare workers and groups at risk. Clinical manifestations of NRLA can range from mild skin disorders to life-threatening systemic reactions. Prevention measures remain the gold-standard treatment for patients suffering from NRLA, but the only etiological therapy able to influence the natural history of NRLA is specific desensitization. This review aims to underline the epidemiological, clinical and diagnostic aspects of NRLA, and carries out a complete and wide-ranging review of the current literature on NRLA management and immunotherapy.Keywords: latex, immunotherapy, desensitization

Nickel (Ni) oral hyposensitization treatment (NiOHT) is an effective management approach for Ni allergy. No healthrelated quality of life (HRQoL) data exist for the pre- and post-treatment with NiOHT in systemic nickel allergy syndrome (SNAS). The aims of this study were (a) to explore HRQoL in SNAS patients, (b) to assess changes of HRQoL after 1 year of NiOHT; (c) to evaluate psychological status of patients. SNAS patients completed the ShortForm 36-Item Health Survey and Psychological General Well-Being Index before and 1 week after the end of NiOHT. Moreover, psychological state was assessed with the Minnesota Multiphasic Personality Inventory (MMPI-2). A total of 52 patients self-reported pre- and post-treatment questionnaires. HRQoL was poor at baseline. After 1 year of NiOHT, all outcome measure scores improved by about 20% with respect to baseline data (P < 0.01 for all indices, except depressed mood). Finally, 33 patients performed the MMPI-2. High rates for hypochondriasis and depression were noted. Furthermore, most of the patients had high scores for anxiety, depression, and health concerns. This is the first study showing that NiOHT improves HRQoL of SNAS patients, which can be considered a “personalized medicine” approach

Introduction: The only etiological and decisive therapy, able to influence the natural history of latex allergy is the specific desensitization. Aim: To verify the clinical efficacy and immunological changes determined by latex sublingual immunotherapy in allergic patients who underwent this treatment for at least 3 years. Material and methods: We enrolled 76 patients (16 males and 60 females, mean age 34 years old) with evidence of a natural rubber latex allergy. To assess the effectiveness of the immunotherapy we performed a latex skin prick test, specific IgE and IgG4 and challenge tests before and after at least 3 years of desensitization. Results: We observed a reduction in the mean diameter of the wheal area at the skin prick test and a decrease in latex specific IgE while no significant changes of latex IgG4 values were found. Moreover a reduction of symptoms and scores at the provocation tests were remarked. Conclusions: Although the primary prevention (which still remains the gold standard treatment for patients suffering from the latex allergy) sublingual immunotherapy can be offered with efficacy in addition to symptomatic treatment to selected patients.

BACKGROUND: Vaccines are very effective medical tools for disease prevention and life span increase. Controversies have raised concern about their safety, from autism to polio vaccine contamination with simian virus 40 (SV-40). Hysteria surrounding vaccine-associated risks has resulted in a declining number of vaccinations in developed countries. Outbreaks of vaccine-preventable diseases (e.g. measles) have occurred in Europe and North America, causing also some causalities. OBJECTIVES: In this review, data on safety and efficacy of vaccines are discussed, showing that the benefits of vaccines far outweigh the risks and that it is important to comply with vaccination protocols, to avoid spreading of severe, preventable diseases. METHODS: Those opposed to vaccinations suggest that scientific literature supporting vaccines is influenced by pharmaceutical companies. In this review, studies on influenza produced by independent scientists and those authored by those who received some kind of benefit from the industry are discussed separately. All the chosen papers were selected through a MEDLINE research. RESULTS: Vaccination rates are decreasing, even though they are effective public health tools. Influenza, for example, is responsible for 250,000-500,000 deaths each year, according to the WHO. Yet, campaigns to extend influenza vaccine to all elderly subjects report little success, because of the vaccine scare and because not all patients develop immunity following vaccination. CONCLUSIONS: This review proves that vaccine hysteria is detrimental because: 1) it causes an increased morbidity and mortality from preventable diseases; 2) it jeopardizes research for new vaccines; 3) patients are reluctant to accept any form of immune-therapy, commonly referred to as "vaccination"
