Abstract

Patient with dizziness are challenging in prehospital care. The aim was to describe final diagnosis among patients assessed by EMS as suffering from dizziness with focus on time-critical conditions. Consecutive patients assessed by an EMS clinician during 12 months in a single large EMS system in Gothenburg, Sweden (660,000 inhabitants), were assessed. The study comprised patients given ESS code 11 dizziness. The main end-point was the final diagnosis (ICD code). There were 58,575 primary missions, of which 2,048 (3.5%) were assessed as ESS code 11 (dizziness). Of these, 161 (8%) were excluded. Among the remaining 1887 cases, there were 230 different ICD codes and 96 (5%) had a time-critical condition. The majority (88%) had a cerebrovascular disease. The most typical symptoms among time-critical conditions were an acute onset (63%) and nausea, vomiting (61%). When compared with non-time-critical conditions, those with time-critical conditions were older and had a higher median systolic blood pressure at EMS arrival. Among primary missions by the EMS, 3.5% had dizziness. Of these, 5% had a time-critical condition and the majority had a cerebrovascular disease. Instruments to identify time-critical conditions among patients seen...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.
