Visualizing Scar Development Using SCAD Assay - An Ex-situ Skin Scarring Assay
Published on: April 28, 2022
Summary
Scabies is a common, itchy skin rash caused by microscopic mites that burrow into the skin. This highly contagious condition affects people of all backgrounds and is not related to personal hygiene.
Area of Science:
- Dermatology
- Parasitology
- Public Health
Background:
- Scabies is a widespread ectoparasitic infection.
- Caused by the mite Sarcoptes scabiei, it presents as an intensely itchy rash.
- Affects all socioeconomic groups globally.
Purpose of the Study:
- To define the etiology and transmission of scabies.
- To elucidate the pathophysiology of the scabies rash.
- To inform public health strategies for scabies control.
Main Methods:
- Microscopic identification of scabies mites.
- Dermatological examination for characteristic burrows and rash.
- Epidemiological data collection on affected populations.
Main Results:
- Scabies mites reside exclusively in the stratum corneum (top skin layer).
- Mites do not penetrate the bloodstream or internal organs.
- Transmission occurs through prolonged skin-to-skin contact.
Conclusions:
- Scabies is a superficial skin infestation by mites.
- It is highly contagious and independent of host hygiene.
- Understanding mite location and transmission is key for management.

01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:30Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
01:22American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
01:27Acne Infection
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...
01:23Skin Diseases and Disorders
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:30Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
