Abstract

Originally introduced by Morton, the concept of hypertrophy of the medial cortex and the entire shaft of the second metatarsal as an objective sign of increased mobility of the first ray has not been subjected to much scrutiny. The goal of the current study was to assess the clinical relevance and reliability of radiographic measures of hypertrophy of the second metatarsal in relation to mobility of the first ray, pes planus, and tightness of the gastrocnemiussoleus in both control subjects and patients with diagnosed disorders of the forefoot. Four study groups of forty-three subjects each were evaluated. The cohort included an asymptomatic control group as well as three groups made up of patients with symptoms and a diagnosis of hallux valgus, hallux rigidus, or interdigital neuroma. Mobility of the first ray (as measured with a device and method described by Klaue et al.), arch height, and ankle dorsiflexion were measured on physical examination. Plain weight-bearing radiographs and previously established equations were used to determine hypertrophy and the length of the second metatarsal, and the hallux valgus and first-second intermetatarsal angles were measured on plain radiographs as well. There was no significant differ...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.
