I read with interest the article by Ozkan and colleagues1 on glandular lesions of the cervix on thinlayer Pap tests. However, a few clarifications need to be made. The authors commented on the difficulty distinguishing endocervical adenocarcinoma in situ (AIS) from high grade squamous intraepithelial lesion (HSIL) involving endocervical glands. Of the 37 ThinPrep® Pap TestsTM (Cytyc Corporation...

Diagnosis of hydatid disease (HD) is usually based on its clinical and radiologic presentation. However, radiologic appearances of bone lesions are nonspecific and mimic inflammatory diseases and neoplasms.6 Despite limited experience with fine needle aspiration biopsy (FNAB) in the evaluation of cystic bone lesions, HD is diagnosed in cytology.1-5 A 33-year-old woman presented with right hip p...

The good name of TEX One of the many wonderful things about TEX is that its behaviour is essentially the same, no matter where it runs. TEX is a fixed point, identical on all machines. The same goes for METAFONT and the Computer Modern fonts. The author of TEX, Donald Knuth, has made it perfectly clear that he does not object to anyone revising TEX(or METAFONT) just as long as the resulting pro...

The Roman imperial monarchy is generally studied from the vantage point of ancient Roman history: the “Roman emperor” is viewed and analyzed as an element of the Roman world. This conventional approach fails to place this institution in a broader comparative context, that of monarchical rulers across world history. Systematic comparison opens up new perspectives and is indispensable in identify...

Uhlmann, J.K.. Satisfying general proximity/similarity queries with metric trees, Information Processing Letters 40 (1991) 175-179. Divide-and-conquer search strategies are described for satisfying proximity queries involving arbitrary distance metrics.

This paper summarizes in a simple and intuitive way why the neutrons, the muons and the solar neutrinos cannot give any significant contribution to the DAMA annual modulation results. A number of these elements have already been presented in individual papers; they are recalled here together with few simple considerations which demonstrate the incorrectness of the claim reported in Davis (PRL 1...

We have explored pattern recognition by examining how observers identify letters. We expected 26-way classification of familiar forms to challenge the popular notion of independent feature detection (“probability summation”), but find instead that this theory parsimoniously accounts for our results. We measured the contrast required for identification of a letter briefly presented in visual noi...

The preliminary results were validated in a prospective series of 353 women. The only difference was that two fingerbreadths tallied with a gestational age of 8 9 weeks (instead of 9 10 weeks). There were 18 false-negatives (5.1%) and 31 false-positives (8.8%). The false-negatives occurred at a mean gestational age of 7.9 weeks (95% confidence interval (CI): 7.1, 8.7). The sensitivity was 93.2%...

To the Editor: In their article, “Geographic distribution of wild rabies risk and evaluation of the factors associated with its incidence in Colombia, 1982–2010,” Brito and colleagues (1) analyzed the spatial distribution of batborne rabies in Colombia and showed an association of occurrence of rabies outbreaks with climatic tendencies. The authors also identified risk clusters for rabies based...
