Stevens-Johnson syndrome (SJS) is an acute mucocutaneous eruption nosologically related to erythema multiforme (EM) and toxic epidermal necrolysis (TEN). Medications are the most common triggering factors for SJS, with anticonvulsants, sulfonamides, penicillins, allopurinol, and nonsteroidal anti-inflammatory drugs (NSAIDs) most commonly implicated. SJS is very rarely associated with tetracycli...

systemic steroids – initially intravenous hydrocortisone 100 mg 8-hourly for 3 days, followed by oral prednisolone 50 mg a day – as well as topical triamcinolone oral paste and an antiseptic mouthwash. She responded well to treatment. Strontium ranelate is a relatively new medication for the treatment of post-menopausal osteoporosis. It simultaneously increases bone formation and decreases bone...

The analysis of covariance is often used in the context of premeasure/postmeasure designs to compare treatment and control groups in both randomized [1] and nonrandomized [2] studies. The intent is to adjust the difference between the changes in the 2 groups for any difference which might exist at baseline, i.e., for any difference between the premeasures in the 2 groups. An important assumptio...

Suppose one has n points, X = {x1, . . . , xn}, in Rd (with d large). If d > n, since the points have to lie in a subspace of dimension n it is clear that one can consider the projection f : Rd → Rn of the points to that subspace without distorting the geometry of X. In particular, for every xi and xj , ‖f(xi)− f(xj)‖ = ‖xi − xj‖, meaning that f is an isometry in X. Suppose now we allow a bit o...

The Johnson-Lindenstrauss lemma shows that a set of n points in high dimensional Euclidean space can be mapped down into an O(log n== 2) dimensional Euclidean space such that the distance between any two points changes by only a factor of (1). In this note, we prove this lemma using elementary probabilistic techniques.

On Saturday, September 19th, local citizens, historians, Civil War enthusiasts, and the rare college student alike converged at the LancasterHistory.org Campus of History for the second day of the President James Buchanan National Symposium. The theme for the symposium was "The Worlds of Thaddeus Stevens and James Buchanan: Race, Gender, and Politics in the Civil War Era," thus it featured the ...
