Dr. Ana Velez speaks about common skin infections that are clinically relevant to the internist and infectious disease physician. She covers the identification of these infections, complications, and medical and surgical management, based on the depth of skin affected. She covers impetigo, erysipelas, cellulitis, fasciitis, and myonecrosis. Some infections mentioned include staphylococcal infections (including MRSA), clostridium, polymicrobial necrotizing fasciitis, Fournier’s gangrene, Pseudomonas folliculitis, and herpes zoster (shingles).

Dr. Pakhi explains how lighter and darker skinned people can be affected by pigmentation and discolouration of the skin. She considers where the color is located, like the epidermis, and suggestions peels and microdermabrasion treatments for dermal and deeper colours. Some pigmentation can be caused by lifestyle choices! New medical video every Tuesday and Thursday.

Psoriasis is a very common inflammatory skin condition affecting about 3% of the world population. It is a CHRONIC disease that evolves in the form of RECURRENT inflammatory flare-ups followed by periods of partial or complete remission. Psoriasis can begin at any age but often develops in young adulthood. The disease may LOOK contagious, but it is NOT.
The most common type, known as PLAQUE psoriasis, is characterized by the presence of red, raised, itchy and SCALY patches of skin. The plaques usually appear on the scalp, in front of the knees and behind the elbows.
Less common types include:
– Guttate psoriasis: lesions occur in the form of SMALL numerous spots over a large area of the body. This type primarily affects children and young adults.
– Inverse psoriasis: SMOOTH patches of inflamed skin that worsen with friction and sweating. These are usually found in between skin FOLDS.
– Pustular psoriasis: an uncommon form with pus-filled, NON-infectious blisters.
– Erythrodermic: a rare but SEVERE, potentially life-threatening form, with WIDEspread lesions all over the body.
Psoriasis has a strong GENETIC component, with multiple genes linked to the SUSCEPTIBILITY to the disease. Most of the identified genes are involved in the immune system, notably inflammatory pathways. In some families, psoriasis is an autosomal DOMINANT trait. Flare-ups can be trigged by a variety of factors, including infections, traumatic injuries, stress, smoking, alcohol use and certain medications. The FIRST lesion usually appears after an upper respiratory tract infection. The exact mechanism is not fully understood but likely to involve an OVERreaction of the body’s inflammatory response. Inflammation DILATES blood vessels, releasing chemicals, resulting in redness and itchiness. Large numbers of activated T-cells infiltrate the epidermis and INDUCE proliferation of skin cells. The cells divide and move up QUICKLY, in the matter of DAYS instead of weeks. This causes cells to build up rapidly on the surface of the skin and form SCALY patches.
Common complications include eye diseases, known as OCULAR psoriasis; and chronic joint inflammation in the fingers and toes, known as psoriatic arthritis. Psoriasis also associates with higher risks of cardiovascular diseases, obesity, diabetes, low self-esteem and depression.
Most people with MILD to moderate psoriasis can be treated effectively with TOPICAL agents. These creams and ointments have several effects: anti-inflammatory, slowing down skin cell growth, and reducing scaling and itching.
Severe psoriasis may benefit from additional treatment such as phototherapy – the use of natural or artificial UV light to SLOW skin cell proliferation and REDUCE inflammation. The exposure time should be controlled to avoid UNwanted skin damage and cancers.
SYSTEMIC treatment is considered when other methods fail. This type of treatment involves ORAL administration or INJECTION of drugs that REDUCE cell growth or SUPPRESS the immune system.

This lecture explains about the the autosomal and x linked inheritance. This video explains the properties of sex linked inheritance and the genetics pedigree.
Autosomal trait is the one where the gene responsible for the trait is carried by Autosomes or body cell chromosomes.
Sex linked trait or X linked trait is the one where the gene responsible for the trait is carried by X chromosomes. So most of the X linked trait is predominant ion male as males have only one X chromosome.

Hello guys welcome back to our channel. Todays video will be about THE 10 Most Common Skin Disorders that human beings suffer.Skin disorders can vary greatly in symptoms and severity. They can be temporary or permanent, and may be painless or painful. Some have situational causes, while others may be genetic. Some skin conditions are minor while others can be life-threatening.
1. Acne (Acne vulgaris) – Acne is the most common skin disorder in the U.S .It is a skin condition that occurs when your hair follicles become plugged with oil and dead skin cells. It often causes whiteheads, blackheads or pimples, and usually appears on the face, forehead, chest, upper back and shoulders. Acne is most common among teenagers, though it affects people of all ages.
2. Atopic dermatitis (Eczema) – The prevalence of Atopic Dermatitis is 7.3 percent among U.S. adults. Atopic dermatitis is one of the most common forms of eczema seen in children. The exact cause of atopic dermatitis is not known, however researchers believe it may involve genetics, the environment, and/or the immune system.

3. Shingles (Herpes Zoster) – Shingles is a viral infection that results from the varicella-zoster virus (VZV), the same virus that causes chickenpox. It typically affects a single sensory nerve ganglion and the skin surface that the nerve supplies. It is estimated that 1 in 3 people in the United States develop shingles during their lifetime.

4. Hives (Urticaria) – Hives are swollen, pale red bumps, patches, or welts on the skin that appear suddenly. They can happen because of allergies or other reasons. Hives are usually itch, but they may also burn or sting. They can show up anywhere on your body, including the face, lips, tongue, throat, and ears. Acute urticaria (hives) affects 15-20% of the general population at some time during their lifetime
