Abstract

OBJECTIVE

The objective of this study was to report clinical outcomes of horses with naturally occurring full-thickness skin lacerations treated with an amorphous silicate dressing. We hypothesized that wounds treated with an amorphous silicate dressing would have minimal complications and lesion resolution without formation of exuberant granulation tissue.

ANIMALS

11 client-owned horses.

PROCEDURES

Clinical records of 11 horses with distal limb wounds treated with an amorphous silicate dressing were collected from participating veterinarians across the US. Wound healing progression was monitored by the veterinarian and owners.

RESULTS

None of the wounds required granulation bed debridement following treatment with topical amorphous silicate dressing. There were no complications associated with the treatment. The size of wounds varied from 5 to 20 cm in length with a median of 10 cm and from 2 to 15 cm in width with a median of 5 cm. Time to resolution varied greatly from 14 to 126 days with a median of 49 days. There was a moderate positive correlation between healing time (days) and area of the wound. All referring veterinarians and owners were satisfied with the healing of the wounds treated with the amorphous silicate dressing.

CLINICAL RELEVANCE

Treatment of equine distal limb wounds with an amorphous silicate dressing may reduce development of exuberant granulation tissue and the need for surgical debridement.

Abstract

OBJECTIVE

To identify associations between admission variables, Animal Trauma Triage (ATT) score, and Modified Glasgow Coma Scale (MGCS) score with need for transfusion or surgical interventions and survival to discharge in cats with bite wounds.

ANIMALS

1,065 cats with bite wounds.

PROCEDURES

Records of cats with bite wounds were obtained from the VetCOT registry from April 2017 to June 2021. Variables included point of care laboratory values, signalment, weight, illness severity scores, and surgical intervention. Associations between admission parameters, terciles of MGCS, quantiles of ATT scores, and death or euthanasia were assessed using univariable and multivariable logistic regression analysis.

RESULTS

872 cats (82%) survived to discharge, while 170 (88%) were euthanized and 23(12%) died. In the multivariable model, age, weight, surgical treatment, ATT and MGCS scores were associated with nonsurvival. For every 1 year of age, odds of nonsurvival increased by 7% (P = .003) and for every 1 kg of body weight, odds of nonsurvival decreased by 14% (P = .005). Odds of dying increased with lower MGCS and higher ATT scores (MGCS: 104% [95% CI, 116% to 267%; P < .001]; ATT: 351% [95% CI, 321% to 632%; P < .001). Odds of dying decreased by 84% (P < .001) in cats that underwent surgery versus those that did not.

CLINICAL RELEVANCE

This multicenter study indicated association of higher ATT and lower MGCS with worse outcome. Older age increased the odds of nonsurvival, while each kilogram increase in bodyweight decreased odds of nonsurvival. To our knowledge, this study is the first to describe associations of age and weight with outcome in feline trauma patients.

Abstract

Antibiotic recommendations for treating skin infections have been published many times in the past 30 years. Prior to 2000, the recommendations focused on the use of β-lactam antibiotics, such as cephalosporins, amoxicillin-clavulanate, or β-lactamase stable penicillins. These agents are still recommended, and used, for wild-type methicillin-susceptible strains of Staphylococcus spp. However, since the mid-2000s there has been an increase in methicillin-resistant Staphylococcus spp (MRSP). The increase among S pseudintermedius in animals coincided with the increase in methicillin-resistant S aureus that was observed in people near the same time. This increase led veterinarians to reevaluate their approach to treating skin infections, particularly in dogs. Prior antibiotic exposure and hospitalization are identified as risk factors for MRSP. Topical treatments are more often used to treat these infections. Culture and susceptibility testing is performed more often, especially in refractory cases, to identify MRSP. If resistant strains are identified, veterinarians may have to rely on antibiotics that were previously used uncommonly for skin infections, such as chloramphenicol, aminoglycosides, tetracyclines, and human-label antibiotics such as rifampin and linezolid. These drugs carry risks and uncertainties that must be considered before they are routinely prescribed. This article will discuss these concerns and provide veterinarians guidance on the treatment of these skin infections.

Abstract

Pruritus in the horse may be due to several causes, the most common being a hypersensitivity response to salivary proteins in the Culicoides genera, which may coexist with atopic dermatitis, also known as an environmental allergy to pollens, molds, dust, storage mites, etc. Less common etiologies are food allergy and contact allergy, the latter often caused by owners applying various products to the skin. Other ectoparasites, such as Chorioptes mites, may also initiate pruritus. Secondary bacterial infections (usually Staphylococcus spp) may be pruritic in and of themselves.

This article reviews the questions that need to be asked of owners to obtain a relevant history, always important for any organ system, but perhaps none more so than the skin. The various clinical findings such as alopecia and crusts and their location on the horse, diagnostic methods such as intradermal or serum testing for allergies, and subsequent hyposensitization are also discussed. Therapeutic options currently available for the potential underlying diseases, in particular for the hypersensitivity reactions to Culicoides spp or environmental allergens, are reviewed with the studies of hyposensitization over the last 40 years, as well as medications that may be effective.

While the most common causes of pruritus in the horse are known, the current understanding of the pathophysiology still needs to be investigated, and consequently, the most effective treatments for those causes need to be improved. Newer research is discussed that may eventually add to the diagnostic and therapeutic options currently available for the pruritic horse.

Abstract

OBJECTIVE

To explore veterinarians’ mental health symptom burden during COVID-19 and identify differences in symptom burden, social support, help seeking, and incentives and barriers associated with receiving help across career stages.

SAMPLE

Online survey responses from 266 veterinarians between June 4 and September 8, 2021.

PROCEDURES

Respondents were grouped by career stage (early [< 5 years of experience], middle [5 to 19 years of experience], or late [≥ 20 years of experience]), and results were compared across groups.

RESULTS

Of the 262 respondents who reported years of experience, 26 (9.9%) were early career, 130 (49.6%) were midcareer, and 106 (40.4%) were late career. The overall mean anxiety and depression symptom burden score was 3.85 ± 3.47 (0 to 2 = normal; 3 to 5 = mild; 6 to 8 = moderate; and 9 to 12 = severe), with 62 of 220 (28.1%) respondents reporting moderate to severe symptom burden. Most (164/206 [79.6%]) reported not accessing behavioral health providers, and of these, 53.6% (88/164) reported at least mild symptom burden. There were significant differences in both symptom burden and mental health help-seeking intentions across career stages, with early- and midcareer (vs late-career) veterinarians reporting higher symptom burden (P = .002) and midcareer (vs late-career) veterinarians reporting higher help-seeking intentions (P = .006). Barriers and incentives for seeking mental health care were identified.

CLINICAL RELEVANCE

Findings revealed differences in symptom burden and intentions to seek mental health care across veterinary career stages. Incentives and barriers identified serve to explain these career stage differences.

Abstract

The primary aim of this article is to provide an overview of several selected skin conditions in livestock species. Topics include ectoparasites in alpacas, antler velvet in reindeer, immune-mediated disease in goats, ectoparasites in pigs, Culicoides allergic dermatitis and parapox infection in sheep. When dealing with skin disease in livestock, it is important to collect a detailed history and undertake a thorough clinical examination to include the axilla, groin, limbs and feet. While the diagnosis will often be anticipated from the history and presentation, it is important to consider a differential diagnosis list and appropriate diagnostic testing before embarking on a poly-pharmacy approach to “rule out” causes of disease. This is particularly important where morbidity is high and the livestock of perceived high value to the keeper/owner, such as goats and small-breed pigs, or when the skin condition is long standing/chronic. Ideally, the management plan should sequentially clarify the role of microbial infection and then ectoparasites before considering less common allergic and autoimmune conditions. Skin cytology is an invaluable in-house diagnostic method that can support the findings of culture. Taking skin samples for histopathology and possibly culture may prove valuable once other diagnostic methods have been explored. Given the need to protect the use of parenteral antimicrobials, topical antimicrobial therapies can be deployed successfully. The repeated use of macrocyclic lactones (avermectins) must be balanced in terms of the risks of promoting anthelmintic resistance versus controlling or eradicating the ectoparasites that have, ideally, been specifically identified.
