There’s a Fungus Among Us!

Ringworm is a fairly common and highly contagious skin, nail, and hair or fur infection that despite its name does not always manifest as a ring and is NOT caused by a worm! Ringworm is actually caused by a fungus! There are several different types of fungi that are responsible for ringworm infections and many of them are zoonotic, meaning the infection can be transmitted to and from both humans and pets. The infection is easily spread by skin to skin contact and from objects or surfaces that have been touched by an infected person or pet such as clothing, towels or bedding, and brushes or combs. The fungi also occur in soil.

So what does a ringworm infection look like?

Symptoms of Ringworm in Pets

Ringworm is not a life-threatening disease, but it is very contagious and does require the intervention of a veterinarian. Knowing the symptoms of ringworm can help you catch the disease before it passes to humans or other pets.

ringworm3aRingworm usually presents as circular areas of hair loss throughout the body. These lesions may start to heal in the center as they enlarge, creating a patchy appearance, and may become inflamed or scabbed.

Ringworm usually does not itch. The affected hair follicles are brittle and break easily, which helps spread the disease throughout your home. In some cases the fungus infects the claws, making them brittle and rough.

Contact your veterinarian if your dog or cat experiences any or all of these symptoms:ringworm3

  • Circular areas of hair loss
  • Dry, brittle hair
  • Scabby, inflamed skin
  • Rough, brittle claws

How is Ringworm diagnosed?

Often your veterinarian can determine from the symptoms your pets has that it is a ringworm infection. There is also a special type of ultraviolet lamp called a Woods Lamp that can be used. Some types of ringworm fungi will fluoresce when exposed to this light.

Unfortunately, not all ringworm infections will fluoresce. Your veterinarian may need to set up a culture to determine the best course of treatment.

How is ringworm treated?

Your veterinarian will determine the best course of treatment. The most common way to treat ringworm is to use a combination of topical therapy (application of creams, ointments or shampoos) and systemic oral therapy (administration of anti-fungal drugs by mouth). In order for treatment to be successful, all environmental contamination must be eliminated.  All surfaces must be cleaned and all bedding should be washed. Humans should be diligent about washing hands frequently and thoroughly. If you suspect you have ringworm you should see your doctor. The earlier the infection can be diagnosed the more the chance of spreading the infection decreases.

Hyperadrenocorticism? Is that even a real word?

What is it?

Hyperadrenocorticism (more commonly known as Cushing’s disease) is an overproduction of cortisol hormone. At normal levels, cortisol helps in response to stress and regulate the immune system. Cushing’s disease is one of the most common endocrine diseases in dogs.

Some common symptoms include:

  • Increased thirstcushings2
  • Increased urination
  • Increased hunger
  • Increased panting
  • Distended abdomen
  • Obesity
  • Loss of hair
  • Muscle weakness and loss
  • Darkening of skin
  • Lack of energy
  • Increased Urine Cortisol:Creatinine Ratios

Not all symptoms are present in every patient and some of these symptoms can also be seen with other diseases. Only your veterinarian can diagnose if your pet has Cushing’s.

There are multiple causes:cushings1

  • Excessive administration of corticosteroid medications.
  • Benign pituitary tumor (rarely can be malignant).
  • Adrenal gland tumor (adrenal-dependent hyperadrenocorticism/ADH).
  • Pituitary-dependent hyperadrenocorticism (PDH) – the body naturally produces too much hormone.

Diagnosis

Your pet’s veterinarian will first take a detailed history and do a complete physical exam. Next step is to perform a full blood chemistry, complete blood count, and urinalysis. These diagnostics will help the veterinarian get a bigger picture of what is happening in the body. Further testing that can help diagnose specific causes include: urine cortisol/creatinine ratio then ACTH stimulation test or Dexamethasone suppression test. The stimulation and suppression tests help determine specifically how much cortisol is being produced and how best it should be treated.

Treatment

  • Excessive administration of corticosteroid medications: Treatment is to slowly wean off the medications according to your veterinarian’s instructions.
  • Benign pituitary tumor and Adrenal gland tumor: First, a metastases check is performed to make sure the tumor has not spread to other organs. Then, a medication is given called trilostane (Vetoryl) to shrink the tumor. Once the tumor has decreased in size, it is removed.
  • Pituitary-dependent hyperadrenocorticism: The pet is put on trilostane for life. This controls the production of cortisol.

Living with Cushing’s Disease

This is a serious disease, but it can be managed if pet owners and veterinarians work together. This is a lifelong diagnosis and does require medications to be given long term. Periodic monitoring will be required to make sure the treatment is going as it should and to help the veterinarians know if an adjustment needs to be made.

Itchy Itchy Scratchy Scratchy – Can you get my Backey?

We all hate allergy season sneezing watery eyes and headaches. Luckily there are medications that relieve us from these symptoms, but did you know that your dogs can get allergies too? Dogs can experience skin luhf,allergies due to the pollen and other substances in the air. Dogs can also experience a chronic inflammatory skin condition called atopic dermatitis that could need lifelong management; in fact 10% of dogs have some kind of atopic dermatitis. Whether it is seasonal allergies or a chronic condition, dogs’ instinct will have them licking, scratching, and chewing at their skin to relieve the itch. This can cause hair loss and major irritation to the skin which can result in skin infections. But don’t worry – relief is just a short drive to your neighborhood veterinarian clinic!

There are medications similar to humans’ Claritin and Zyrtec, that are given orally on a daily basis. But what if those don’t help or your dog doesn’t like to take pills? Another option? Cytopoint, an injection that can relieve itch for 4-8 weeks. Cytopoint is a protein based (not chemical) medication that works similar to the cytodog’s immune system. When the “itching” signal is sent by your dog’s body to the brain it causes the reaction to start scratching or chewing. Cytopoint intercepts that signal to prevent your pet from scratching and allowing their skin to heal working similar to antibodies in their immune system. Because Cytopoint is not a chemical medication dogs’ bodies are able to break it down naturally. Meaning it does not get eliminated through the liver and kidney so no harm can be done to your pets’ organs. This makes it safe for dogs of all ages and can be used alongside other medications your pup may be taking.

If you and your veterinarian decide Cytopoint injections are the best option for your furry friend, they can began feeling relief within 1 day and damaged skin can begin to heal within 7 days. After the first injection your vet may want to see your dog in 4 weeks to see the progress of the Cytopoint after which the two of you can discuss how often your dog may need an injection. The idea is to extend the time between shots and get your dog longer relief.  Your veterinarian will help you recognize signs that it is time for your pup to get their next injection. Another helpful tool is the itch tracker located on the Cytopoint website (https://www.cytopoint4dogs.com/resources.aspx), this chart can help you determine when it is time to bring your pet in for the next injection.

If you think your dog has allergies or an atopic dermatitis, set up an appointment with your veterinarian and ask about using Cytopoint. Start the journey to a longer itch free lifestyle because both you and your dog deserve relief from allergies!

Creepy Crawly Skin Mites

Is your pet loosing hair on their face/around eyes/mouth/ears for no reason? They might be scratching themselves silly or not at all? It is a possibility that your pet has mange. Luckily, this is a treatable disease.

Kinds of Mange

  • Demodectic Mange “Demodex”
  • Sarcoptic Mange “Scabies”

Demodectic Mange “Demodex” is a mite that is normally found in the hair follicles of all cats and dogs, but can become a health problem when found in excessive amounts. The immune system usually keeps the mite numbers in check. Demodex mites can become excessive if the animal has a compromised immune system (ex. puppies, poor nutrition, stressed animals, parasite infestation, or chronic disease). Demodex is commonly found in young animals (3 months-1 year old) and animals that have had a history of demodex earlier in life. Demodex mites in canines are named Demodex canis and demodex mites in felines are named Demodex cati and Demodex gatoi. There are three different forms of demodex: Localized (isolated spots on body), Generalized (entire body is affected), and Demodectic Pododermatitis (paws are just affected).

Clinical SignsUntitled2

  • Alopecia (hair loss) on face, around eyes, mouth, and ears. If severe case, they can have hair loss on forelegs and trunk too.
    • The mites feed on the hair follicle, which is what makes the hair fall out.
  • Erythema (redness) with crusty patches can be seen. When this is seen it is called “Red Mange”.
  • In severe cases (Generalized Demodex) the animal can have a fever, whole body hair loss, and a secondary skin infection.
  • The most important clinical sign is that the animal is NONPURITIC (not itchy). This helps identify Demodex compared to other mange mites.

Diagnosis

  • Skin scraping. After treatment, the animal should be rechecked twice and have two negative scrapings to verify that treatment is working.
  • Culture if secondary skin infection is present.

Treatment Options

  • Oral treatments
  • Topical treatments
  • Injections
  • Shampoos/Dips
  • Oral antibiotics if secondary skin infection present.
  • In the old days there was a myth that dipping the animal in motor oil was a good home remedy. This is FALSE. Motor oil can cause severe rashes and destroy healthy skin. It can also be absorbed through the skin and cause blood pressure issues. PLEASE – do not dip you animal in motor oil.

Untitled1Prognosis

  • Prognosis is good in localized and pododermatitis forms if proper treatment is followed.
  • The generalized form of Demodex can be fatal because of the severity of infection.
  • Demodex canis and Demodex cati are not contagious to humans and other animals.
  • Demodex gatoi is contagious to other animals and all animals in the household should be treated.
  • It is important to know that treatments will never completely remove the mites. It will just help control them to normal numbers so it does not affect the animal’s skin.
  • Relapse is possible because every mite cannot be killed, but it is more likely to happen if no recheck skin scrapes were preformed. Relapse is common 6-12 months after treatment.
  • Breeders should not use previously infected animals because it can be hereditary.

Prevention

  • There is currently no preventative measures against Demodex. There are a few simple things you can do to avoid it. A healthy immune system can help prevent the recurrence of mange. It’s therefore important to keep your dog on a regular feeding schedule, with lots of water and healthy meals, and plenty of exercise.

Sarcoptic Mange “Scabies” is a mite that burrows into the epidermis and lays eggs. This causes severe itching and inflammation within the skin. Scabies can infest almost all species of haired animals. It is very contagious to other animals and humans by direct contact. Scabies can occur in dogs/cats of any age, sex, or breed. Canine scabies mites are named Sarcoptic scabiei and feline scabies mites are named Notoedres cati.

Clinical Signs

  • Red, crusty lesions on ears, elbows, and trunk of animal.
  • Severely puritic (itchy)
    • This distinguishes it from Demodectic Mange
  • Secondary bacterial skin infections due to self trauma from itching.

Diagnosis

  • Skin scraping
  • Skin biopsies

Treatment Options

  • Oral treatments
  • Topical treatments
  • Injections
  • Shampoos/Dips
  • Antibiotics to control secondary bacterial skin infection
  • Anti-itch medications

Prognosis

  • Prognosis is good if proper treatment is followed and the secondary bacterial infection is not extreme.
  • Animals can remain contagious for 2-4 weeks during treatment.
  • If you see red papules on yourself there is a chance you could have scabies. Contact your physician.

Prevention

  • There is currently no preventative measures against Scabies. There are a few simple things you can do to avoid it. A healthy immune system can help prevent the recurrence of mange. It’s therefore important to keep your dog on a regular feeding schedule, with lots of water and healthy meals, and plenty of exercise. Also avoid contact with infected animals.
