THE SO-CALLED PRESYSTOLIC MURMUR,

Presystolic murmur in atrial fibrillation.

tI he lollowing eschange was aicepted tor publication in October l976. Due to space constraints relating to submission of original airticles its publication had to be delayed. To the Editor: Doctors Tavel and Bonner in their recent editorialt have advanced a detailed and compelling refutation of the concept that a presystolic murmur can occur in mitral stenosis with atrial fihrilla-tion. We wel...

The so-called Stabilizer Theorem

Theorem 1.1 (Hrushovski’s Theorem 3.5). Let G be a definable group, X a definable subset, and G̃ be the ∨-definable group generated by X. Suppose all this data is defined over a model M . Suppose μ is an M-invariant translation-invariant ideal on subsets of G̃. Let q be a wide type over M , contained in G̃. Identify q with its ∧-definable set of realizations. Suppose (F) there exist two realizatio...

So-called hypertrophic emphysema.

Before discussing the pathogenesis and clinical aspects of this disease, clarification of some of the pertinent terminological definitions may be in order. Hypertrophic emphysema is the most commonly used designation of this disease. Also, it is known under the following names: genuine emphysema, idiopathic emphysema, diffuse vesicular emphysema, obstructive emphysema, dystrophlc emphysema, pul...

Preventing those so-called stillbirths.

Increased recognition of the disproportionately large contribution of newborn health to global child survival has fuelled efforts to address neonatal mortality in resource-limited settings. Stillbirths have not been as well studied despite the fact that more than 3 million stillbirths occur annually, a disease burden that approaches that of postnatal deaths. The poorest countries have the highe...
