The nationwide prevalence of latent tuberculosis infection (LTBI) in Italian patients with psoriasis has never been investigated. To estimate the nationwide prevalence of LTBI in Italian patients with psoriasis who are candidates for systemic treatment. Data were obtained from the Psocare Registry on those patients (n=4946) with age >18years, systemic treatment at entry specified and tuberculin skin test (TST) performed according to the Mantoux method. LTBI diagnosis was based on a positive TST result in the absence of any clinical, radiological or microbiological evidence of active tuberculosis. Latent tuberculosis infection was diagnosed in 83% of patients with psoriasis (409 of 4946). The prevalence of LTBI was lower in patients on biologics than in those on conventional systemic treatments, ranging from 43% (19 of 444) of patients on adalimumab to 31% (eight of 26) of those on psoralen-ultraviolet A (P<005). Independent factors associated with LTBI were male sex [odds ratio (OR) 130, 95% confidence interval (CI) 104-162; P=002], age over 55years (OR 293, 95% CI 218-393; P<0001) and being entered into a conventional treatment (OR 383, 95% CI 310-474; P<0001). Positive history of tuberculosis was seen in 1% of patients (n=49). The nationwide prevalence of LTBI in Italian patients with psoriasis candidate to systemic treatment is high, and screening is recommended prior to biological treatment.

We're always looking for well-written reviews of books, music, movies, television shows, websites, video games and other products. When writing a review, concentrate on exactly what you liked or didn't like. Give examples of strengths and weaknesses, be descriptive and provide background information on an author, director, actor or musician, if possible. Find professional reviews in magazines or newspapers and see how reviewers deal with their topic, but be sure to express your own voice in your review. Grammar Hint for Reviews: When describing a book, movie, album or anything else, use the present tense. Book Reviews Discuss an author's technique, strengths and weaknesses instead of focusing on the plot. Does the story flow? Is there a strong sense of character and place? Did you stay up until dawn to finish it? Is it good reading for teenagers? What influence did it have on you and why? If you've read other books by the same author, discuss how this book compares. Movie Reviews Think of the major Oscar categories and consider the performances, music, lighting and setting, etc. Do these work together? Did some hold up while others didn't? If the movie is based on a book, discuss whether one is better than the other and why. If the movie is a remake, compare the film to its original. Remember that a well-written movie review should discuss strengths and weaknesses. Some readers may not have seen a movie yet, so don't give away an exciting scene or the ending! College Reviews Begin by providing an overview of the college, including location, size and a description of the campus and/or dorm life. Think about all aspects of your college visit. What academic, athletic and after-class programs are available? What are the students like? What makes the college different from others? Every school has strengths and weaknesses. Be objective. Consider what the school has to offer and who might enjoy or benefit the most from attending there.
Which aspects should be included in all three reviews?
