First-line therapy for disseminated or localized instances of pyoderma gangrenosum is systemic treatment by corticosteroids and ciclosporin. Topical application of clobetasol, mupirocin, and gentamicin alternated with tacrolimus can be effective.

Pyoderma gangrenosum ulcers demonstrate pathergy, that is, a worsening in response to minor trauma or surgical debridement. Significant care should be taken with dressing changes to prevent potentially rapid wound growth. Many patients respond differently to different types of treatment, for example some benefit from a moist environment, so treatment should be carefully evaluated at each stage.

Papules that begin as small "spouts" can be treated with Dakins Solution to prevent infection and wound clusters also benefit from this disinfectant. Wet to dry applications of Dakins can defeat spread of interior infection. Heavy drainage can be offset with Coban dressings. Grafting is not recommended due to tissue necrosis.

If ineffective, alternative therapeutic procedures include systemic treatment with corticosteroids and mycophenolate mofetil; mycophenolate mofetil and ciclosporin; tacrolimus; thalidomide; infliximab; or plasmapheresis.

There is currently a phase III trial for the use of the IL-1B modulating agent gevokizumab in treating the ulcers of pyoderma gangrenosum.

Intertrigo is treated by addressing associated infections, by removing moisture from the site, and by using substances at the site to help maintain skin integrity. If the individual is overweight, losing weight may also help. Relapses of intertrigo are common.

Keeping the area of the intertrigo dry and exposed to the air can help prevent recurrences, as can removing moisture from the area using absorbent fabrics or body powders, including plain cornstarch and judiciously used antiperspirants.

Greases, oils, and barrier ointments, may help by protecting skin from moisture and from friction. Antifungal powders, most commonly clotrimazole 1%, may also be used in conjunction with a barrier ointment. Diaper rash ointment can also help.

Fungal infections associated with intertrigo may be treated with prescription antifungals applied directly to the skin (in most cases) or systemic antifungals, including fluconazole, nystatin, and griseofulvin.

Intertrigo is also a known symptom of vitamin B6 deficiency.

Medications with good evidence include ivermectin and azelaic acid creams and brimonidine, doxycycline, and isotretinoin by mouth. Lesser evidence supports metronidazole cream and tetracycline by mouth.

Metronidazole is thought to act through anti-inflammatory mechanisms, while azelaic acid is thought to decrease cathelicidin production. Oral antibiotics of the tetracycline class such as doxycycline and oxytetracycline are also commonly used and thought to reduce papulopustular lesions through anti-inflammatory actions rather than through their antibacterial capabilities.

Using alpha-hydroxy acid peels may help relieve redness caused by irritation, and reduce papules and pustules associated with rosacea. Oral antibiotics may help to relieve symptoms of ocular rosacea. If papules and pustules persist, then sometimes isotretinoin can be prescribed.

The flushing and blushing that typically accompanies rosacea is typically treated with the topical application of alpha agonists such as brimonidine and less commonly oxymetazoline or xylometazoline.

Treating rosacea varies depending on severity and subtypes. A subtype-directed approach to treating rosacea patients is recommended to dermatologists. Mild cases are often not treated at all, or are simply covered up with normal cosmetics.

Therapy for the treatment of rosacea is not curative, and is best measured in terms of reduction in the amount of facial redness and inflammatory lesions, a decrease in the number, duration, and intensity of flares, and concomitant symptoms of itching, burning, and tenderness. The two primary modalities of rosacea treatment are topical and oral antibiotic agents. Laser therapy has also been classified as a form of treatment. While medications often produce a temporary remission of redness within a few weeks, the redness typically returns shortly after treatment is suspended. Long-term treatment, usually one to two years, may result in permanent control of the condition for some patients. Lifelong treatment is often necessary, although some cases resolve after a while and go into a permanent remission. Other cases, left untreated, worsen over time.

Sweating causes lesions to form, but lesions aggravated by sweat usually return to "normal" fairly quicklyavoiding sweat is not a reason to avoid exercise. Minor outbreaks can be controlled with prescription strength topical cortisone creams. More severe eruptions usually clear up after treatment for one to three months with Accutane or tetracycline. If these fail or the outbreak is severe, PUVA phototherapy treatments, antifungal pills and cortisone injections are alternatives.

Some research has suggested a correlation of Grover's disease with mercury toxicity in which case Dimercaptosuccinic acid might help.

Large doses of glucocorticoids are the treatment of choice, and are administered until the signs have resolved. In uncomplicated cases, this can take up to a month. If dogs are not treated promptly and with high doses of steroids, severe scarring may occur. If there is evidence of secondary bacterial infection, treatment with antibiotics is required.

Acne treatment may require oral tetracycline antibiotics or isotretinoin. Treatments directed at tumor necrosis factor (TNF) (infliximab, etanercept) and interleukin-1 (anakinra) have shown a good response in resistant arthritis and pyoderma gangrenosum. Other traditional immunosuppressant treatments for arthritis or pyoderma gangrenosum may also be used.

Commonly used dietary supplements include:

- Omega-6 fatty acids (e.g., safflower or sunflower oil)

- Omega-3 fatty acids (e.g., fish oils)

- Vitamin A.

Immunosuppressant and anti-inflammatory therapy serves to stop on-going destruction of the sebaceous glands. Like other inflammatory diseases, most animals receive an initial course to stop the inflammation and treatment is tapered off to the lowest dose that keeps the disease in remission. Oral cyclosporine may be used. Corticosteroids (e.g. prednisone) are used only if pruritus is a major clinical feature.

Other treatments include lindane, benzyl benzoate, crotamiton, malathion, and sulfur preparations. Lindane is effective, but concerns over potential neurotoxicity have limited its availability in many countries. It is banned in California, but may be used in other states as a second-line treatment. Sulfur ointments or benzyl benzoate are often used in the developing world due to their low cost; Some 10% sulfur solutions have been shown to be effective, and sulfur ointments are typically used for at least a week, though many people find the odor of sulfur products unpleasant. Crotamiton has been found to be less effective than permethrin in limited studies. Crotamiton or sulfur preparations are sometimes recommended instead of permethrin for children, due to concerns over dermal absorption of permethrin.

Systemic corticosteroids such as (prednisone) can produce rapid improvement and are the “gold standard” for treatment. The temperature, white blood cell count, and eruption improve within 72 hours. The skin lesions clear within 3 to 9 days. Abnormal laboratory values rapidly return to normal. There are, however, frequent recurrences. Corticosteroids are tapered within 2 to 6 weeks to zero.

Resolution of the eruption is occasionally followed by milia and scarring. The disease clears spontaneously in some patients. Topical and/or intralesional corticosteroids may be effective as either monotherapy or adjuvant therapy.

Oral potassium iodide or colchicine may induce rapid resolution.

Patients who have a potential systemic infection or in whom corticosteroids are contraindicated can use these agents as a first-line therapy.

In one study, indomethacin, 150 mg per day, was given for the first week, and 100 mg per day was given for 2 additional weeks. Seventeen of 18 patients had a good initial response; fever and arthralgias were markedly attenuated within 48 hours, and eruptions cleared between 7 and 14 days.

Patients whose cutaneous lesions continued to develop were successfully treated with prednisone (1 mg/kg per day). No patient had a relapse after discontinuation of indomethacin.

Other alternatives to corticosteroid treatment include dapsone, doxycycline, clofazimine, and cyclosporine. All of these drugs influence migration and other functions of neutrophils.

Pyoderma means any skin disease that is pyogenic (has pus). These include superficial bacterial infections such as impetigo, impetigo contagiosa, ecthyma, folliculitis, Bockhart's impetigo, furuncle, carbuncle, tropical ulcer, etc. Autoimmune conditions include pyoderma gangrenosum. Pyoderma affects more than 111 million children worldwide, making it one of the three most common skin disorders in children along with scabies and tinea.

Oral ivermectin is effective in eradicating scabies, often in a single dose. It is the treatment of choice for crusted scabies, and is sometimes prescribed in combination with a topical agent. It has not been tested on infants, and is not recommended for children under six years of age.

Topical ivermectin preparations have been shown to be effective for scabies in adults, though only one such formulation is available in the United States at present, and it is not FDA-approved as a scabies treatment. It has also been useful for sarcoptic mange (the veterinary analog of human scabies).

Intertrigo refers to a type of inflammatory rash (dermatitis) of the superficial skin that occurs within a person's body folds. These areas are more susceptible to irritation and subsequent infection due to factors that promote skin breakdown such as moisture, friction, and exposure to bodily secretions such as sweat, urine or feces. Areas of the body which are more likely to be affected by intertrigo include the inframammary fold, intergluteal cleft, armpits, and spaces between the fingers or toes. Skin affected by intertrigo is more prone to infection than intact skin.

The term "intertrigo" commonly refers to a secondary infection with bacteria (such as "Corynebacterium minutissimum"), fungi (such as "Candida albicans"), or viruses. A frequent manifestation is candidal intertrigo.

Intertrigo occurs more often in warm and humid conditions. Generally, intertrigo is more common in people with a weakened immune system including children, the elderly, and immunocompromised people. The condition is also more common in people who experience urinary incontinence and decreased ability to move.

Pseudomonal pyoderma is a cutaneous condition, a superficial infection of the skin with "P. aeruginosa".

Pentoxifylline is a useful add on treatment to compression stockings and may also help by itself. It works by reducing platelet aggregation and thrombus formation. Gastrointestinal disturbances were reported as a potential adverse effect.

Sulodexide, which reduces the formation of blood clots and reduces inflammation, may improve the healing of venous ulcers when taken in conjunction with proper local wound care. Further research is necessary to determine potential adverse effects, the effectiveness, and the dosing protocol for sulodexide treatment.

An oral dose of aspirin is being investigated as a potential treatment option for people with venous ulcers. A 2016 Cochrane systematic review concluded that further research is necessary before this treatment option can be confirmed to be safe and effective.

Oral zinc supplements have not been proven to be effective in aiding the healing of venous ulcers, however more research is necessary to confirm these results.

Many canine skin disorders can have a basis in poor nutrition. The supplementation of both omega fatty acids, 3 and 6, have been shown to mediate the inflammatory skin response seen in chronic diseases. Omega 3 fatty acids are increasingly being used to treat pruritic, irritated skin. A group of dogs supplemented with omega 3 fatty acids (660 mg/kg [300 mg/lb] of body weight/d) not only improved the condition of their pruritus, but showed an overall improvement in skin condition. Furthermore, diets lacking in essential fatty acids usually present as matted and unkept as the first sign of a deficiency. Eicosapentaenoic acid (EPA), a well known omega 3, works by preventing the synthesis of another omega metabolite known as arachidonic acid. Arachidonic acid is an omega 6, making it pro-inflammatory. Though not always the case, omega 6 fatty acids promote inflammation of the skin which in turn reduces overall appearance and health. There are skin benefits of both these lipids, as a deficiency in omega 6s leads to a reduced ability to heal and a higher risk of infection, which also diminishes skin health. Lipids in general benefit skin health of dogs, as they nourish the epidermis and retain moisture to prevent dry, flaky skin.

Pyoderma gangrenosum is a condition that causes tissue to become necrotic, causing deep ulcers that usually occur on the legs. When they occur, they can lead to chronic wounds. Ulcers usually initially look like small bug bites or papules, and they progress to larger ulcers. Though the wounds rarely lead to death, they can cause pain and scarring.

The disease was identified in 1930. It affects approximately 1 person in 100,000 in the population. Though it can affect people of any age, it mostly affects people in their 40s and 50s.

Vitamins are one of many of the nutritional factors that change the outward appearance of a dog. The fat soluble vitamins A and E play a critical role in maintaining skin health. Vitamin A, which can also be supplemented as beta-carotene, prevents the deterioration of epithelial tissues associated with chronic skin diseases and aging. A deficiency in vitamin A can lead to scaly of skin and other dermatisis related issues like alopecia Vitamin E is an antioxidant. Vitamin E neutralizes free radicals that accumulate in highly proliferative cells like skin and prevent the deterioration of fibrous tissue caused by these ionized molecules. There are also a couple of water-soluble vitamins that contribute to skin health. Riboflavin (B2) is a cofactor to the metabolism of carbohydrates and when deficient in the diet leads to cracked, brittle skin. Biotin (B7) is another B vitamin that, when deficient, leads to alopecia.

Blastomycosis-like pyoderma (also known as "Pyoderma vegetans") is a cutaneous condition characterized by large verrucous plaques with elevated borders and multiple pustules.

Two layers of skin created from animal sources as a skin graft has been found to be useful in venous leg ulcers.

Artificial skin, made of collagen and cultured skin cells, is also used to cover venous ulcers and excrete growth factors to help them heal. A systematic review found that bilayer artificial skin with compression bandaging is useful in the healing of venous ulcers when compared to simple dressings.

Studies on the treatment of cryofibrinoginemic disease have involved relatively few patients, are limited primarily to case reports, and differ based on whether the disease is primary or secondary. In all cases of cryofibrinogenemic disease, however, patients should avoid the exposure of afflicted body parts to cold weather or other environmental triggers of symptoms and avoid using cigarettes or other tobacco products. In severe cases, these individuals also risk developing serious thrombotic events which lead to tissue necrosis that may result in secondary bacterial infections and require intensive antimicrobial therapy and/or amputations. Careful treatment of these developments is required.

Treatment of secondary cryofibrinoginemic disease may use the same methods used for treating the primary disease wherever necessary but focus on treating the associated infectious, malignant, premalignant, vasculitis, or autoimmune disorder with the methods prescribed for the associated disorder. Case report studies suggest that: corticosteroids and immunosuppressive drug regimens, antimicrobial therapy, and anti-neoplastic regimens can be effective treatments for controlling the cryfibrinoginemic disease in cases associated respectively with autoimmune, infectious, and premalignant/malignant disorders.

What happens after your child is diagnosed with CRMO/CNO?

Find a doctor who has experience with patients with CRMO/CNO. CRMO/CNO in children is generally treated by a pediatric rheumatologist. Ask your doctor for a referral.

Why do we treat CRMO/CNO?

- Reduce inflammation

- Prevent bone damage and bone deformities

- Decrease pain

How is CRMO/CNO treated?

CRMO/CNO is different for each patient. Not every child responds to every treatment. Your doctor may need to try several medications before finding the one that works for your child. In severe cases, doctors may combine medications to treat the disease. Your doctor will work with you and your child to help find the best treatment.

For some CRMO/CNO patients, the disease can be managed with non-steroidal anti-inflammatory drugs (NSAIDs). NSAIDs are the first line treatment. However, if NSAIDs are not effective, or if your child does not tolerate NSAIDs well, second line treatments are available.

First line treatments include Naproxen (Aleve), Celecoxib (Celebrex) Meloxicam (Mobic), Piroxicam (Feldene), Indomethacin (Indocin), Diclofenac (Voltaren).

Second line treatments include corticosteroids (Prednisone/Prednisolone), Methotrexate (Otrexup, Rasuvo, Trexall), Sulfasalazine (Azulfidine), Pamidronate (Aredia), Zolendronic Acid (Zometa), Adalimumab (Humira), Etanercept (Enbrel), Infliximab (Remicade).

These medications are also used in children with other inflammatory and/or bone conditions. Side effects may occur while taking these medications. Your physician will have a discussion with you prior to starting any new treatment.

Grover's disease (GD) is a polymorphic, pruritic, papulovesicular dermatosis characterized histologically by acantholysis with or without dyskeratosis. Once confirmed, most cases of Grover's disease last six to twelve months, which is why it was originally called "transient". However it may last much longer. Nevertheless, it is not to be confused with relapsing linear acantholytic dermatosis.
