Abstract

AIDS patients often present without visual symptoms despite severe vision-threatening cytomegalovirus (CMV) retinitis. A new self-examination chart, the Teich Target (copyright 1993, Steven A. Teich, pat. no. 370259), which tests the central 45 degrees of vision, was evaluated for its ability to screen AIDS patients for CMV retinitis. It was compared with the Amsler grid (which tests the central 20 degrees of vision) in 50 consecutive AIDS patients referred for ophthalmologic evaluation by a single practitioner. Of 19 patients found to have CMV retinitis, 12 (63%) noted scotomas with the Teich Target compared with 7 (37%) with the Amsler grid (p < 0.05). Overall, 13 of 20 (65%) infectious retinitis cases were detected by the Teich Target. and 7 of 20 (35%) with the Amsler grid (p < 0.05). All scotomas noted on the Amsler grid were detected by the Teich Target. Four visually asymptomatic patients with newly diagnosed CMV retinitis noted scotomas only with the Teich Target. Both methods detected a branch retinal artery occlusion, but only the Teich Target detected a quadrantanopsia due to cerebral toxoplasmosis. There were no false positives with either method. In this small series, the Teich Target was more effective than the Am...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
