Epilepsy in Dogs

by admin on April 1st, 2017

Category: News, Tags:

Epilepsy means repeated or recurrent seizures or “fits” due to abnormal activity in the brain. Electrical activity is happening in the brain all the time however in some patients an additional and abnormal burst of electrical activity can occur which causes a fit. Some dogs will just have one fit but in others it becomes a regular event – this is Epilepsy. It is important to realise that Epilepsy is not a disease in itself but the sign of an abnormal brain function. The most commonly diagnosed form of epilepsy is referred to as Primary Epilepsy and is more common in certain breeds. Epilepsy does occur in cats but is much less common.

Are all fits the same?

No and as It is very likely your vet won’t see the fit taking a short video can be extremely helpful to them in deciding on the best course of action. Many types of seizure have been described in dogs and cats. The most common type is the grand mal which is the dramatic, typical fit where the patient lies on the floor and the whole body twitches and convulses rhythmically. Partial epileptic seizures that affect only one part of the body can also occur. These are less common and can be difficult to differentiate from other unusual non-epileptic movement disorders.

The seizure frequency is extremely variable between dogs (from many seizures a day to a seizure every few months). Despite being born with this functional brain disorder, dogs with primary epilepsy usually do not start seizuring before the age range of 6 months to 6 years. In the absence of disease affecting the brain, animals are typically normal in between the epileptic seizures.

 

What causes epilepsy?

The exact mechanism is unknown but in many cases the tendency to develop epilepsy is thought to be passed on genetically. In Primary epilepsy there is no obviously abnormal brain tissue and it is due to a chemical imbalance or to some ‘faulty wiring’ in the brain.

 

What is Secondary Epilepsy?

Secondary epilepsy is when the fits are being caused by another brain disorder such a brain tumour, an inflammation or infection of the brain (encephalitis), a brain malformation, a recent or previous stroke or head trauma. In other words there is an identifiable cause for the regular fits and there is some structurally abnormal brain tissue.

 

How is Epilepsy diagnosed?

The diagnosis of primary epilepsy is unfortunately a diagnosis of exclusion after elimination of other causes. There is no definitive diagnostic test for this condition and all investigations such as blood tests, brain scans and laboratory analysis of the cerebrospinal fluid (CSF), which surrounds the brain and spinal cord, will all come back as completely normal!

 

Can you cure epilepsy?

Primary Epilepsy is unfortunately a condition that the animal is born with and as such it cannot be cured. Using anti-epileptic medication such as phenobarbitone will prevent some patients having any more fits. Although complete control is the goal of treatment, in most circumstances ‘successful treatment’ is a balancing act of reducing the frequency and severity of the seizures to a low level whilst avoiding unacceptable side effects of the drugs. So a patient may still have some fits despite being on treatment.

 

When should medication be started?

This isn’t a black and white issue. A substantial number of dogs will only have one fit in their entire lifetime and so if every dog was started on treatment after its first fit then all these dogs would be receiving medication unnecessarily. However, there is some evidence to suggest that early treatment offers better long-term control of the seizures as compared to animals that are allowed to have numerous seizures prior to the onset of treatment.  We also have to take into account that anti-epileptic medications can have side effects and getting things under control will often place significant demands on you as the pet owner and carer.

Pet of the Month – April 2017 – Diarmuid

by admin on April 1st, 2017

Category: Pet of the Month, Tags:

Meet Diarmuid a handsome six month old flat coated retriever. Diarmuid has Distichiasis (‘extra eyelashes’).

Distichiasis is a common condition in dogs. It occurs when eyelashes are abnormally positioned and emerge too close to the eyelid margin.

Distichiasis can occur in any breed of dog but is most commonly seen in the American Cocker and Cocker Spaniel, Miniature and Longhaired Dachshund, Bulldog and Weimeraner breeds.

 

What are the signs of distichiasis?

In many dogs the extra eyelashes do not cause a problem, but in some cases they can rub the surface of the eye and cause irritation. The most common signs that you will notice are increased blinking/squinting of the eye, increased watering, and redness of the ‘white’ of the eye.

 

What are the treatment options for distichiasis?

Distichiasis only requires treatment if the hairs are causing irritation, conjunctivitis or corneal ulceration. There are a number of treatment options:

  • Ocular lubricants. In mild cases of distichiasis, daily use of a lubricating gel such as Viscotears, Geltears or Lacrilube may be sufficient to soften the hairs and reduce their irritation. Lifelong treatment will be required.
  • Plucking.   Sometimes the extra eyelashes can be plucked using special epilation forceps. This is particularly useful when there are only a few long hairs present. However, because the hairs will grow back after a few weeks, regular and lifelong treatment will be needed.
  • Electrolysis. Under general anaesthesia, a fine electrode is inserted into each hair follicle and a current is applied to permanently destroy the hair follicle. Once the hair follicle is destroyed the distichia cannot regrow. However, because only those hairs that happen to be present at the time of treatment can be identified and removed, new hairs may emerge at a later date and also cause irritation. The success rate of electrolysis per treatment is around 70-80%. The procedure can be repeated a number of times if necessary. Rarely, electrolysis can cause some scarring and depigmentation of the eyelids, but this is not usually severe.
  • Cryotherapy. This technique may be useful when many hairs are present. Under general anaesthesia, a probe is applied to the inner surface of the eyelid in the region of the hair follicles. Via this probe, the eyelid is frozen to destroy the hair follicles. The technique can cause some scarring and depigmentation of the eyelids. This procedure may also need to be repeated, and has a similar success rate to electolysis.
  • Surgery. Excision of a very small portion of the eyelid margin from which the distichia are growing.

As the few distichia do not appear to be bothering Diarmuid’s eyes excessively, artificial tears are being used alone at present. Should the distichiasis become more of a problem then intervention along one of the lines described above will be necessary

Elbow Dysplasia in Dogs

by admin on March 1st, 2017

Category: News, Tags:

Elbow Dysplasia simply means ‘abnormal development of the elbow joint’. The term Elbow Dysplasia includes a number of specific primary problems that affect different sites within the elbow joint. These include:
    • Elbow Dysplasia'Osteochondrosis or osteochondritis dissecans(OC or OCD)
    • Fragmented coronoid process (FCP)
    • Ununited anconeal process (UAP)

These conditions may be related to a poor fit between the three bones that make up the elbow joint. This poor fit or ‘incongruity’ can be seen on X-rays or by CT or MRI examination. In some patients, it may be difficult to identify because it is only present when the dog does certain activities, and sometimes this poor fit may have been present briefly during the dog’s development and is no longer present when investigations are performed.

These primary problems tend to develop when the puppy is only a few months of age and will commonly affect both elbow joints. Once a primary problem has started, secondary change soon follows. Secondary change takes the form of abnormal joint wear and arthritis. These secondary changes may have consequences for the rest of the dog’s life.

 

Are certain breeds prone to getting Elbow Dysplasia?

Elbow Dysplasia is a significant problem in many breeds worldwide. It is recognised in numerous breeds although large breeds seem to be most affected – particularly Labrador Retrievers, Newfoundlands, Golden Retrievers, Boxers, Rottweilers and German Shepherd Dogs. As investigation methods have improved we are increasingly recognising it in smaller breeds too.

 

Why do dogs get Elbow Dysplasia?

Elbow Dysplasia is a multifactorial disease which means that a number of factors influence its occurrence. Genetics plays an important role although the precise genetic basis of Elbow Dysplasia remains undetermined. Other factors that are thought to influence the disease include growth rate, diet, and level of activity.

 

How do I know if my pet has Elbow Dysplasia?

Not all dogs with Elbow Dysplasia will show obvious clinical signs of lameness. This may be because the condition is mild or because similar changes exist in both elbows which may mask the lameness. Clinically affected dogs with Elbow Dysplasia commonly show stiffness or lameness between 5 and 12 months of age. Typically owners describe that their dog is stiff after rest and after exercise but improves with light activity. Others will observe that their dog’s front feet begin to turn out. It is thought that this is an adaptation to elbow pain and is the dog’s way of relieving it.

 

What tests may be required?

Clinical examination may determine that the elbow joint is painful or swollen, although initially, the lameness may be difficult to localise to a particular joint. Confirmation of the diagnosis of Elbow Dysplasia is made by performing further investigations which would typically be X-rays or CT examination. X rays will often be able to determine whether your dog has elbow dysplasia either by identifying the primary problem or the osteoarthritis that occurs as a result. Three bones (humerus, radius, and ulna) combine to form the elbow joint and these overlap on radiographs. This makes identification of the primary lesion problematic in some cases.

Elbow radiographs and CT/MRI scans are important tests for detecting elbow dysplasia in dogs. CT/MRI examination is an excellent method of looking at the detailed structure of the joint and determining the precise nature of Elbow Dysplasia. It provides additional information to radiography and this can be useful when planning surgical treatments, especially in more complex cases.

Pet of the Month – March 2017 – Prince

by admin on March 1st, 2017

Category: Pet of the Month, Tags:

Our pet of the month this March is a delightful and photogenic Pomeranian puppy called Prince.

Prince had to have his right foot X-rayed after he jumped off a bed and landed awkwardly. Unfortunately, in the process he fractured all the toes of his right paw and was unable to bear weight on it.

Following surgery to stabilise the fractures using small metal pins we are really pleased to report Prince is making good progress and hopefully will be back to normal very soon.

Pet of the Month – February 2017 – Hadley

by admin on February 1st, 2017

Category: Pet of the Month, Tags:

Hadley has featured in this column before and his return to this newsletter is to highlight the need for vigilance in respect of skin tumours. Hadley suffers from a very serious form of skin cancer called a Mast Cell Tumour (MCT), and he is recovering very well following surgery to remove yet another recurrence. MCT can be very deceptive as they often start as small bumps which may remain static for many months before growing larger. It can be extremely difficult to contain, frequently recurs and may be life threatening.

MCT is the most common skin tumour in dogs; it can also affect other areas of the body, including the spleen, liver, gastrointestinal tract, and bone marrow. MCT represent a cancer of a type of blood cell normally involved in the body’s response to allergens and inflammation. Certain dogs are predisposed to MCT, including brachycephalic (flat-faced) breeds such as Boston Terriers, Boxers, Pugs, and Bulldogs, as well as retriever breeds, though any breed of dog can develop MCT.

When they occur on the skin, MCT varies widely in appearance. They can be a raised lump or bump on or just under the skin, and may be red, ulcerated, or swollen. In addition, many owners will report a waxing and waning size of the tumour, which can occur spontaneously or can be produced by agitation of the tumour, causing degranulation. Mast cells contain granules filled with substances which can be released into the bloodstream and potentially cause systemic problems, including stomach ulceration and bleeding, swelling and redness at and around the tumour site, and potentially life-threatening complications, such as a dangerous drop in blood pressure and a systemic inflammatory response leading to shock.

When MCT occur on the skin, they can occur anywhere on the body. The biological behaviour of these tumours can vary widely; some may be present for many months without growing much, while others can appear suddenly and grow very quickly. The most common sites of MCT spread (metastasis) are the lymph nodes, spleen and liver.

Diagnosis can be simply achieved via a fine needle aspirate. This requires no anesthesia and only rarely sedation. Early identification and surgical removal are key to the most favourable outcomes however aggressive forms may require radical surgery and necessitate referral to a specialist cancer referral centre.

Hadley initially found the operation sites to be very itchy after surgery, something not uncommon with MCT. After removing a few of his own sutures Hadley was given additional medication, resutured and had to wear a full body suit! We are pleased to report he is making very good progress.

Head Tilt In Dogs

by admin on February 1st, 2017

Category: News, Tags:

What does it mean if my dog has a Head Tilt?

A persistent head tilt is a sign of a balance (vestibular) centre problem in dogs. It is very similar to ‘vertigo’ in people and is often accompanied by a ‘drunken’ walk and involuntary eye movements, either side to side or up and down.

The feeling that the room is spinning due to the eye movements is what causes a feeling of nausea in both people and dogs. The signs may not be as severe as mentioned here and can just consist of a mild head tilt. Signs often seen associated with a head tilt but unassociated with balance abnormalities include a facial ‘droop’ and deafness.

Causes of a head tilt

A head tilt represents a disorder of the balance centre. However, the balance centre resides in the inner bony portion of the ear as well as the brain. So a head tilt could represent a simple ear problem or a very serious brain disease.

Ear problems which are responsible for head tilts include:

  • Infections
  • Polyps
  • Reactions to topical drops or solutions if the ear drum is damaged
  • Hits to the head
  • (Occasionally) ear tumours
  • (Rarely) a genetic abnormality affecting puppies, especially those of the Doberman breed
  • Idiopathic vestibular disease

The most common cause is what is called idiopathic vestibular disease. There is no known cause of this disease, a variant of which is also seen in people. The signs can start very suddenly and be accompanied by vomiting in severe cases. This condition, however, will resolve given time without any specific treatment.

Brain diseases responsible for balance centre dysfunction can include:

  • Tumours
  • Trauma
  • Inflammation
  • Stroke
  • Rarely, similar signs can be seen in dogs that are receiving a specific antibiotic called metronidazole. Recovery will often take place within days of stopping this medication

Clinical signs of vestibular disease – is it the ear or is it the brain?

In addition to a head tilt, signs of vestibular disease (balance centre dysfunction) include ataxia (a drunken, falling gait) and nystagmus (involuntary eye movements). There are several signs to look for which help separate out whether the origin of the disease is inner ear or brainstem (Central Nervous system – CNS).

Central nervous system localisation will often be associated with weakness on one side of the body that can manifest as ‘scuffing’ or even dragging of the legs, in addition to lethargy, and sometimes problems eating and swallowing, or loss of muscle over the head.

A balance problem associated with an inner ear disease is not likely to be associated with any of these signs. However, some dogs will exhibit a droopy face and a small pupil on the same side as the head tilt.

 

Tests recommended for a dog with a head tilt

Evaluation of an animal with a head tilt includes physical and neurologic examinations, routine laboratory tests, and sometimes x-rays. Your veterinary surgeon may carry out a thorough inspection of the ear canal, which may require sedation of your dog – this can be useful to rule out obvious growths or infections. Additional tests may be recommended based on the results of these tests or if a metabolic or toxic cause is suspected. Identification of specific brain disorders requires imaging of the brain, such as magnetic resonance imaging (MRI). Collection and examination of cerebrospinal fluid, which surrounds the brain, is often helpful in the diagnosis of certain inflammations or infections of the brain.

 

How do we treat head tilt in dogs

Treatment for vestibular dysfunction will focus on the underlying cause once a specific diagnosis has been made. Supportive care consists of administering drugs to reduce associated nausea and/or vomiting. Travel sickness drugs can be very effective. These must only be given following advice from your veterinary surgeon. Protected activity rather than restricted activity should be encouraged as this will potentially speed the improvement of the balance issues.

 

Outlook (prognosis) for head tilt in dogs

The prognosis depends on the underlying cause. The prognosis is good if the underlying disease can be resolved and guarded if it cannot be treated. The prognosis for animals with an idiopathic vestibular disease is usually good because the clinical signs can improve within a couple of months.
