Concurrent Varicella-Zoster Virus Reactivation and Recurrent Herpes Simplex Virus Infection in the C2 Dermatome With Varicella-Zoster Virus Encephalitis: A Case Report and Review of the Literature.

Herpes simplex virus (HSV) and varicella-zoster virus (VZV) are common viruses that are present in the general population. However, it is uncommon for both viruses to coincide at the same time and location. These viruses infect the nervous system to establish latency and have been associated with neurological disorders.

What's Eating You? Tropical Rat Mite (Ornithonyssus bacoti).

The tropical rat mite (Ornithonyssus bacoti) commonly infests wild and pet rodents, but they are not host specific. Bodily contact with wild or domesticated rodents is the most common source of infestation. Mites can live off many mammal hosts for a long period of time; therefore, living in quarters infested by mice can lead to mite exposure.

Bacteriophages: An Alternative to Combat Antibiotic Resistance?

Antibiotic resistance has become one of the largest pitfalls of modern medicine, and this has fueled the search for a safe and effective alternative. Of these alternatives, bacteriophage (phage) therapy has emerged as a potential option since it is capable of destroying pathogenic bacteria, without disrupting commensal bacterial populations. Although numerous studies have shown its efficacy in various conditions such as dysentery, sepsis, and meningitis, very little research has focused on its prospective usage to treat dermatological conditions.

Considerations for cutaneous physiologic changes of pregnancy that fail to resolve postpartum.

Pregnancy prompts many adaptive and unique physiologic modifications, with cutaneous changes being possibly the most noticeable. These cutaneous changes are of interest to physicians, since they must be diagnosed as anticipated normal physiologic changes or potentially harmful and managed accordingly. Research has been conducted on physiologically normal and abnormal cutaneous manifestations of pregnancy but is lacking in regard to the persistence of these changes after delivery.

DMSO: an aid to combat pain and pruritus.

Dimethyl sulfoxide (DMSO) is a highly reactive by-product of paper production in the form of an odorless, colorless liquid that has been studied since the 1860s. Initially it was utilized as a solvent, but more recently it is being investigated for therapeutic applications. Owing to its versatility, the use of DMSO has been proposed in many different medical fields for a variety of applications, with possibly the widest use being in the field of dermatology.

Pain and Pruritus: a study of their similarities and differences.

Pruritus is one of the most common dermatologic complaints and, as the most common dermatologic symptom, is a major contributor to frequent dermatology visits. Chronic pruritus mirrors another major medical condition faced by millions of Americans each year - chronic pain. In older literature, pain and pruritus were thought to have been conveyed by the same C fiber, and the proportion contributing to pruritus was just a small subset of this general fiber.
