Sickle cell trait as a risk factor for secondary hemorrhage in children with traumatic hyphema

American Journal of Ophthalmology

Abstract

To determine risk factors for secondary hemorrhage and poor visual outcome in children with traumatic hyphemas. We reviewed 99 eyes of 97 children younger than 18 years who had been hospitalized for hyphema within 48 hours of blunt eye trauma. Inpatient records were examined for race, age, sickle cell trait status, size of hyphema and intraocular pressure at admission, secondary hemorrhage (rebleed of hyphema), and medications while hospitalized. Fifty-five eyes of 53 children had at least 1 month of follow-up or attained best-corrected visual acuity of 20/50 or better at their last outpatient visit. Among 99 eyes of 97 children with traumatic hyphema, secondary hemorrhage occurred in nine eyes (9%). Among 72 eyes of 70 African-American children, secondary hemorrhage occurred in nine eyes (14%), whereas in 27 eyes of 27 white children, there were no secondary hemorrhages. However, when the 14 eyes of 13 sickle cell trait-positive children were excluded from the African-American group, the 57 eyes of sickle cell trait-negative African-American and white children did not have any secondary hemorrhages. The sickle cell trait-positive group had secondary hemorrhages in nine of 14 eyes (64%), significantly (P < .005) different from ...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.
