Stroke Mimic: A Case of Unilateral Thyrotoxic Hypokalemic Periodic Paralysis
Thyrotoxic hypokalemic periodic paralysis (THPP) is a condition that results in transient skeletal muscle paralysis secondary to intracellular potassium sequestration. Susceptible individuals often have an underlying channelopathy, which may be exacerbated by lifestyle factors or underlying medical comorbidities such as hyperthyroidism or diarrheal illness. Classically, THPP presents with paralysis of proximal extremity musculature. In this case, we present a rare case of unilateral THPP. Such a presentation is relevant to emergency physicians as it mimics a stroke or transient ischemic attack and should be considered on the differential for unilateral neurologic deficits
What is Apophaticism? Ways of Talking About an Ineffable God
Apophaticism -- the view that God is both indescribable and inconceivable -- is one of the great medieval traditions of philosophical thought about God, but it is largely overlooked by analytic philosophers of religion. This paper attempts to rehabilitate apophaticism as a serious philosophical option. We provide a clear formulation of the position, examine what could appropriately be said and thought about God if apophaticism is true, and consider ways to address the charge that apophaticism is self-defeating. In so doing we draw on recent work in the philosophy of language, touching on issues such as the nature of negation, category mistakes, fictionalism, and reductionism
Dilations and constrained algebras
It is well known that unital contractive representations of the disk algebra
are completely contractive. Let A denote the subalgebra of the disk algebra
consisting of those functions f whose first derivative vanishes at 0. We prove
that there are unital contractive representations of A which are not completely
contractive, and furthermore provide a Kaiser and Varopoulos inspired example
for A and present a characterization of those contractive representations of A
which are completely contractive. In the positive direction, for the algebra of
rational functions with poles off the distinguished variety V in the bidisk
determined by (z-w)(z+w)=0, unital contractive representations are completely
contractive.Comment: New to version 2 is a proof of rational dilation for the
distinguished variety in the bidisk determined by (z-w)(z+w)=
