Alopecia is defined as the loss of hair in areas of the body where normal hair would be expected. Alopecia can represent a mere cosmetic problem with no risk to the patient, however, it can also occur as a consequence of an internal disease with potentially serious implications. As such, a methodical approach and an accurate diagnosis are prerequisites for the correct management of alopecia cases.

The first step in approaching alopecia is to assess whether the hair loss is primary and not associated with inflammation, or whether, on the contrary, it is due to self-trauma (broken hairs, erosions) or skin inflammation.

The clinical examination should, therefore, initially aim to identify signs of follicular inflammation and infection that must be differentiated from clinical alterations associated with non-inflammatory alopecic diseases. Erythema, papules, pustules, lichenification, self-trauma recognized by broken hairs, excoriations, erosions and ulcerations are suggestive of an inflammatory process associated with pruritus.

In the case of non-inflammatory alopecia, a mere cosmetic problem, with no risk to the patient, may be present, or the alopecia may be the manifestation of a systemic disease. In this case, there can be potentially serious consequences for the patient if the condition is not correctly identified and corrected.

With this class we intend to provide the appropriate tools for a correct identification of the clinical signs associated with the different types of alopecia, as well as for its correct diagnosis.

  • Otitis externa (OE) is defined as an acute or chronic inflammation of the external ear canal. In dogs, it is a very common alteration, being reported to represent up to 20% of all visits seen in the daily small animal clinic. In cats, otitis externa is less common, accounting for about 4% of all medical cases. Although it is often considered a diagnosis, otitis externa is just a clinical sign, almost always resulting from an underlying primary cause, almost always involving a secondary infection, and in which other predisposing and perpetuating factors also contribute to the disease. For the effective management of all cases of otitis, these factors must be identified and controlled.
  • Otitis media (OM) usually occurs as an extension of otitis externa and can occur in up to 80% of cases of chronic otitis, being a frequent cause of therapeutic failure in the management of OE.
  • With this class we intend to define the most appropriate therapeutic approaches taking into account the different clinical scenarios.

  • Unlike dogs, external otitis (OE) is much less frequent in cats, being a reason for consultation in only 2% of cases.
  • The primary causes of otitis externa in cats differ to some extent from those in dogs, requiring an adapted and specific diagnostic approach.
  • The purpose of this talk is therefore to summarize the various causes associated with the development of otitis externa in cats.

  • One of the most frequent veterinary consult complaints is otitis externa (OE). Approximately 20% of all canine patients have some type of ear disease.
  • Otitis externa occurs as a consequence of a multitude of causes and factors. Primary causes result in ear canal inflammation, predisposing factors increase the risk for the development of otitis, and perpetuating factors delay a clinical cure. The control of these factors is the key to avoid chronicity and recurrence of otitis externa.
  • The purpose of this lecture is, therefore, to summarize the various factors and causes associated with canine otitis externa development.

  • Feline atopic syndrome is a chronic disease and allergenic avoidance, when possible, is the best possible option. If this is not possible, a combination of etiological, symptomatic and nutritional therapies must be instituted, depending on each case
  • The purpose of this lecture is, therefore, to summarize the various treatment options for feline atopic syndrome

  • Cats show unique reactive and lesional patterns in their skin conditions. These reaction patterns reflect the skin's response to various inflammatory stimuli, and they are just that in themselves: patterns, not definitive diagnoses.
  • The most common reaction patterns are usually indicative of allergic disease, however, other differential diagnoses, such as infectious and parasitic diseases, should be systematically considered and excluded.
  • The most common reaction patterns are: self-induced alopecia; head and neck pruritus; miliary dermatitis; eosinophilic granuloma complex.
  • The goals of this class will be to present the clinical presentation of the cutaneous reaction patterns considered characteristic of feline atopic syndrome.

  • Historically, in the treatment of pyoderma, empirical systemic antibiotic therapy based on the clinical presentation was considered adequate, with an emphasis on the selection of an adequate antibiotic dose and duration of treatment.
  • With the recent emergence of multi-resistant bacteria, the approach to pyoderma has changed, and the correct diagnosis through cytological analysis and bacterial culture is now of great importance as it allows us to ensure the responsible use of systemic antibiotic therapy.
  • The objectives of this class are to provide keys for a correct choice of the most appropriate treatment for different types of pyoderma.

  • Scaling is an accumulation of loose debris from the stratum corneum (corneocytes). Scaling can have various appearances and be dry, thin, slab or greasy and vary in color from white, silver, yellow, brown or grey.
  • Corneocytes are the end product of epidermal keratinization and the normal loss of these cells is not visible to the naked eye as corneocytes are released individually or in small groups. In abnormal scaling, there is a loss of large scales. Scaling may be primary in primary idiopathic seborrhea and ichthyosis. However, scaling is more often secondary to a chronic inflammatory process. In the presence of pruritus, the differential diagnosis should include parasitic infections, allergies, infectious diseases such as pyoderma or Malassezia dermatitis.
  • If pruritus is not present, differential diagnoses should include primary endocrinopathies, demodicosis, dermatophytosis, leishmaniasis, nutritional imbalances, metabolic diseases, and cutaneous neoplasia such as cutaneous epitheliotropic lymphoma. In cats, exfoliative dermatitis associated or not with thymoma should also be considered.

  • LED is a relatively benign, autoimmune condition that affects the dog's nasal planum and in which systemic manifestations are absent.
  • It is the second most common immune-mediated skin pathology in dogs.
  • Exposure to ultraviolet light aggravates and exacerbates LED and there are breeds that may be predisposed since they are reported more frequently, as the Collie, Shetland Sheep Dog, Australian Shepherd, German Shepherd and Siberian Husky.
  • Therapeutic approaches are multiple and different effectiveness has been reported.

  • In recent years, new therapeutic options have been developed for the management of CAD, and, in parallel with the evolution in the knowledge of the pathophysiology of this condition, a new way of looking at the manner we use these new therapies has also emerged.
  • Currently, a proactive therapeutic approach is emphasized in which, while correcting the underlying pathogenesis whenever possible, active relapses are actively prevented, through a constant control of the inflammation associated with the allergic condition.
  • In this new therapeutic approach, the management of CAD is done in two phases:
  • A first phase of REACTIVE therapy, in which the active clinical signs (pruritic and lesional being acute or chronic) is rapidly controlled in order to induce clinical remission;
  • A second phase of PROACTIVE therapy with the goal of preventing relapses, through the regular control of subclinical inflammation.
