Abstract

To determine the frequency and computed tomography (CT) characteristics of ovarian cysts in women of different ages. Five hundred ninety-five contrast-enhanced CT studies performed in 430 females aged 10 or older between January 2001 and December 2006 were retrospectively reviewed. For each study, we recorded the presence of ovarian cysts larger than 5 mm in diameter, with or without a hyperenhancing rim (HR, NR). The frequencies and CT characteristics of HR and NR cysts were analyzed according to phase of the menstrual cycle and patient age. Independent-sample t test, analysis of variance, chi test, and Fisher exact test were used to compare continuous data and categorical data between groups. Ovarian cysts were more frequently seen on CT studies of women between the ages of 20 and 49 years than on those of women older than 50 years (P = 0.004). Cysts with no HR were seen in every age group; HR cysts were present only in patients younger than 50 years. Cysts with HR were seen more frequently during periovulatory and secretory phase than during menses and proliferative phase (P = 0.003). Cysts with HR had a mean volume of 1.8 cm; NR cysts had a mean volume of 5.3 cm (P = 0.004). Cysts with HR had a thicker wall (3.4 mm vs imper...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.
