Thrombocytopenia with absent radii (the TAR syndrome)
The American Journal of the Medical Sciences
|September 1, 1980
Abstract:
The congenital association of thrombocytopenia and absent radii has been designated the TAR syndrome. This article describes a female with the TAR syndrome who presented with the first known onset of hemorrhagic phenomenon at the age of 47, the oldest age of onset described in the literature. The incidence, clinical manifestations, differential diagnosis, course, and effects of treatment of the syndrome are reviewed, and proposed etiologic factors are discussed.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
