Herpes gladiatorum: Facts, Symptoms, Causes, Risk Factors, Diagnosis, Treatments, Prevention and Outlook.


Herpes gladiatorum is an infection caused by herpes simplex virus type 1, a virus similar to that which causes cold sores. It is common among those who engage in high-contact sports, such as wrestling, and is also known as mat herpes. Those infected with herpes will carry the virus with them for life as there is no cure.




There will be periods where the virus is inactive and no symptoms are present, and times where it is active and causes various symptoms and flare-ups.

When the virus is active, the person carrying it is infectious and can spread herpes gladiatorum to others. The virus can be transmitted by skin-to-skin contact and is easily passed from one person to the next.

In this article, we examine the symptoms of herpes gladiatorum and the parts of the body that can be affected. We also take a look at diagnosis, treatment, and prevention of the condition.

Urinalysis Quality Control at the Point-of-Care !


The goal of any clinical diagnostic test procedure is to provide critical information in a timely manner so that appropriate actions may be taken, ultimately improving patient outcomes. Point-of-care testing (POCT) is a term that has come to describe a multitude of rapid medical tests that can be performed at or near the site of patient care. The most compelling benefit of these tests is that, as opposed to having to wait hours or days for results to arrive from an outside laboratory, clinicians can obtain the results immediately, allowing for clinical management decisions to be made while the patient is still at the care facility. While the implementation of rapid diagnostic tests dates back to ancient history (sweet-tasting urine was once commonly used to diagnose diabetes mellitus), it was not until the 1950s that these rapid diagnostic methods gained any real predictive value. Today, the popularity and demand for POCT are increasing rapidly. TriMark Publications estimates that the global market for POCT was $14.5 billion in 2016, and is expected to grow by seven percent over the next five years.




Urinalysis dipsticks at the point-of-care:


Urinalysis using multi-analyte dipsticks is a point-of-care test performed at any hospital, clinical laboratory, doctor’s office, health clinic, and nursing facility. Various iterations of these tests have existed for decades, and they continue to be among the most commonly performed tests of any kind. Urinalysis dipsticks contain discrete reagent pads to semi-quantitatively test for the presence of bilirubin, blood, creatinine, glucose, ketones, leukocytes, nitrite, pH, protein, specific gravity, and urobilinogen in a urine sample.

The Growing Impact of Cardiac Biomarkers in Clinical Chemistry.

Clinical chemistry measurements and calculations take into account an expansive set of analytes that reflect cardiac, liver, kidney, and other biological functions. Several of these discrete analytes are considered biomarkers, defined by Strimbu and Tavel as “a broad subcategory of medical signs [that are] objective indications of medical state observed from outside the patient which can be measured accurately and reproducibly.” In the case of cardiac biomarkers, the most common analytes are creatine kinase (CK), lactate dehydrogenase (LDH), and troponin (TNI). There are pros and cons to using these common chemistry tests as definitive cardiac biomarkers. However, other chemistry analytes and even some non-laboratory tests have been identified as potential cardiac biomarkers. Providing clinicians with accurate and thorough testing is important in contributing to diagnosis and ultimately to positive patient outcomes.
