Growth failure: an unusual clinical problem

An unusual eigenvalue problem

We discuss an eigenvalue problem which arises in the studies of asymptotic stability of a self-similar attractor in the sigma model. This problem is rather unusual from the viewpoint of the spectral theory of linear operators and requires special methods to solve it. One of such methods based on continued fractions is presented in detail and applied to determine the eigenvalues.

An unusual airway problem.

ON WE~Y ~A~E OCCASIONS it may be necessary to ventilate each lung separately in association with major injuries to the trachea. A double lumen tube (e.g. Carlens tube) may be unsatisfactory ff the defect in the trachea is of such a location and magnitude as to allow an air leak when the tracheal cuff is inflated. The following is a ease report describing the management of the airway of a patien...

An Unusual Suspect Causing Hypoxemic Respiratory Failure

Introduction: Antisynthetase syndrome (ASS) is characterized by the presence of anti-Jo-1 antibodies in conjunction with clinical findings of fever, polymyositis-dermatomyositis, and interstitial lung disease (ILD). Inflammatory myopathies carry a high risk of malignancy, but this association is less well outlined in ASS. We present the case of a patient with ASS who developed non-Hodgkin's lym...

An unusual cause of heart failure.

Pelvic arteriovenous malformations (AVMs) are uncommon entities that can present with symptoms resulting from compression of adjacent structures, ischemia due to 'steal phenomenon' or, rarely, heart failure. We present a case of heart failure in a patient who presented to our facilities for heart transplant and a prior diagnosis of idiopathic dilated cardiomyopathy; further evaluation revealed ...
