A recent study has provided evidence that the use of contralateral prophylactic mastectomy (CPM) is increasing.[1] Over the 5-year period from 1998 to 2003, the CPM rate doubled. Prior studies have shown that the surgical procedures chosen by patients are most commonly influenced by physician and surgeon recommendation. This has been observed in the choice of CPM as well.[2] The data strongly s...

TO THE EDITOR—We read with interest the article by Lamagni et al that describes a steady rise from 700–800 to 1652 per annum during the 1991–2010 period of invasive group B streptococcus (GBS) infections in England and Wales, most pronounced among adults [1]. This was identified based on routine microbiology laboratory reports undertaken across these countries through an automated biosurveillan...

PURPOSE This study was conducted in order to demonstrate changing trends in colorectal cancer incidence according to sex, age group, and anatomical location in the Korean population. MATERIALS AND METHODS Data from the Korea Central Cancer Registry between 1999 and 2009 were analyzed. Annual percent changes (APCs) of sex- and age-specific incidence rates for cancer of the proximal colon (Inte...

Recent reports have shown increased sensitization to Methylchloroisothiazolinone/methylisothiazolinone. We report a retrospective study conducted at the Hospital das Clínicas--UFMG, based on the results of patch tests with the Brazilian standard series, performed on referred patients. The positive results in 359 patients from November 2009 to October 2012 were analyzed and compared with the pre...

It was recently discovered by Baik, Deift and Johansson [4] that the asymptotic distribution of the length of the longest increasing subsequence in a permutation chosen uniformly at random from Sn, properly centred and normalised, is the same as the asymptotic distribution of the largest eigenvalue of an n × n GUE random matrix, properly centred and normalised, as n → ∞. This distribution had e...

In a famous paper 8] Hammersley investigated the length L n of the longest increasing subsequence of a random n-permutation. Implicit in that paper is a certain one-dimensional continuous-space interacting particle process. By studying a hydrodynamical limit for Hammersley's process we show by fairly \soft" arguments that limn ?1=2 EL n = 2. This is a known result, but previous proofs (Vershik-...

We compute the limit distribution for the (centered and scaled) length of the longest increasing subsequence of random colored permutations. The limit distribution function is a power of that for usual random permutations computed recently by Baik, Deift, and Johansson (math.CO/9810105). In the two–colored case our method provides a different proof of a similar result by Tracy and Widom about t...
