The human clinical manifestations of staphylococcic infections of the eyelids, conjunctiva, and cornea are discussed. The corneal lesions occurring during the course of staphylococcic infections of the lid develop after the disease has been present in the eyelid for several years, but are not always correlated with the degree of activity. The peripheral infiltrations and ulcerations either are ...

Uniformly severe corneal infections were produced in rabbits by intracorneal injection of a few viable Pseudomonas aeruginosa. The bacteria multiplied rapidly, and within 24 hr, about 10 million organisms were present. The numbers remained stable thereafter. Polymorphonuclear leukocytes (PMNs) began to infiltrate peripheral stroma 24 hr after inoculation. By 32 hr, ring-shaped dense accumulatio...

Experiments were designed in a bioassay system to analyze the effect of elevated (from 5.9 mM to 7.5-45.9 mM) extracellular K+ concentration on the release of endothelium-derived relaxing factor. Segments of canine femoral artery with endothelium (donor segment) were mounted in an organ bath and perfused with modified Krebs-Ringer bicarbonate solution; the effluent from the donor segment was us...

Two cases of corneal cysts are reported, one sclerocorneal and the other intracorneal. The two conditions differ in pathogenesis, appearance, course, and management.

Introduction: Double aortic arch (DAA) is a congenital anomaly of the aortic arch. It is the most common type of complete vascular ring. When it occurs, the connected segment of the aortic arch and its branches encircle the trachea and esophagus, leading to symptoms related to these two structures. Case Report: We present a case of a newborn baby who developed biphasic stridor immediately after...
