Emergencias en Dermatología?

In the present conference we will differentiate between those diseases that are potentially life-threatening (emergency) from those that are not (urgency).

Since the enclosed time of the conference we will develop only some of them and provide concepts for others.

Urgency

Hot spot: hot patch that is triggered by any pathology that causes itching or pain.

Juvenile cellulitis: pseudopyoderma, adiva puppies or juvenile pyoderma. It is an immune-mediated disease that usually affects puppies under 4 months of age.

Acute otitis: associated with pruritic diseases such as AD.

Acute itching in AD or sarcoptic mange: pruritus intensity is such that it immediately requires attention.

Angioedema: generalized edema that primarily affects the head.

Hives: flat elevations that appear and disappear rapidly.

Small burns.

Pharmacodermy or drug adverse reactions.

Located vasculitis: the classic example is the thromboembolism that usually occurs in some breeds such as Dachshund.

Erythema multiforme is an uncommon disease in dogs characterized by a sudden onset of inflammatory skin disease. Erythema multiforme may have a moderate course and spontaneous regression after a few weeks.

Emergencies

Burns over large body surfaces.

Pharmacodermy or drug adverse reactions.

Stevens-Johnson syndrome is believed to come from a disorder of the immune system. The immune reaction can be caused by infections, drugs or medications. In some groups, the drug reaction can be intensified by genetic factors.

Toxic epidermal necrolysis is a rare, life-threatening, ulcerative vesiculobullous disorder of the skin and mucous membranes. Toxic epidermal necrolysis and Stevens-Johnson syndrome in humans are thought to be the same disease, the second one being less extensive and severe. It is considered an adverse drug reaction.

Non-traditional pemphigus foliaceus presentation: this explosive presentation of pemphigus, crowned with collarettes and widespread crusts, characterized by unusual speed manifestation, requires prompt treatment.

Chronic pruritus: Some dogs are often euthanized in cases of uncontrollable pruritus caused primarily by chronic allergies.

Pyoderma caused by methicillin-resistant bacteria.

Chronic otitis: In general, many dogs are often euthanized for this cause since there are often resistant bacteria.

Generalized vasculitis: Vasculitis is a reaction characterized by a mistaken immune response, mainly directed to blood vessels. The pathophysiology is unclear and includes a variety of mechanisms that act inducing necrotic and inflammatory changes in the wall of blood vessels. It may be cutaneous or systemic. The most common injuries are erythema, plaques and hemorrhagic bullae, hives and serpiginous lesions and sometimes edema. Then, necrosis comes and can result in crater-like ulcerative lesions. The lesions can appear anywhere on the body including oral cavity and mucous membranes. Vasculitis treatment requires immunomodulatory drugs. In less severe cases, doxycycline or pentoxifylline are used.
