Simple Summary: Intralymphatic immunotherapy is a treatment used for allergic diseases in both humans and animals. While ultrasound-guided injections were initially common, palpation-based injections have become more popular in veterinary dermatology. Precise injection into the lymph node seems crucial for the treatment's effectiveness; therefore, this study aimed to evaluate the impact of injection method (ultrasound guidance vs. palpation-based) on clinical responses in dogs with atopic dermatitis. The retrospective analysis of 129 canine atopic dermatitis cases treated with ILIT between 2014 and 2022 found that dogs receiving ILIT via ultrasound guidance had a significantly higher success rate compared to palpation-based injections. These findings suggest that injection quality may influence treatment outcomes. Further research is needed to validate these findings. Background: Intralymphatic immunotherapy (ILIT) has been used successfully in both human and veterinary medicine as a safe and effective treatment for allergic diseases. Initially, ILIT was administered by ultrasound guidance, but palpation-based injections have become more popular among veterinary dermatologists. Data from human medicine, however, show that precise injection into the lymph node is mandatory, and injection quality clearly correlates with clinical response. Hypothesis: Our aim was to assess the impact of the injection method (ultrasound guidance versus palpation-based guidance) on clinical response in dogs with atopic dermatitis. Methods: A total of 129 canine atopic dermatitis (CAD) cases treated with ILIT between 2014 and 2022 were retrieved from the hospital clinical database. The included dogs had to receive at least three intralymphatic injections administered either by palpation or ultrasound guidance. Those cases were retrospectively assessed and compared regarding clinical response to ILIT. Results: In total, 84 dogs received ILIT by ultrasound guidance, and in 25 dogs, ILIT was injected based on palpation. The success rate of ILIT was significantly higher in the ultrasound guidance group when compared to palpation-based injections. Conclusions: Low-quality injections must be considered as a possible reason for ILIT failure in dogs. Further prospective and controlled studies are necessary to confirm these results.

Background Objectives Methods and Materials Results Conclusions and Clinical Relevance Dermatological cases are commonly encountered worldwide. Dermatology specialists and a specific dermatology curriculum may not be available in some parts of the world.This study's first objective was to describe the dermatology curricula at a sample of American and Indonesian veterinary schools. The second objective was to investigate veterinary students' opinions regarding their readiness and confidence in managing dermatological cases.Two online questionnaires were designed and distributed to veterinary schools in both Indonesia and the United States. One questionnaire was designed to evaluate the details of the dermatology coursework and distributed to a conveniently selected representative faculty of each school via email. The other questionnaire, which was distributed to veterinary students through a listserv, surveyed students' opinions about their education. Data were analysed using descriptive statistics and thematic data analysis.In the United States, 63.7% of responding veterinary schools had a specific faculty member teaching dermatology. Dermatology coursework was mandatory in 55% and 0% of schools in the United States and Indonesia, respectively. Ten of 11 responding US schools offered dermatology rotations, yet this was only required for graduation in three schools. None of the Indonesian schools offered a dermatology rotation. Students in both countries reported that they were confident in their clinical skills regardless of the presence of a board‐certified dermatology referral clinician.Our study presents an updated insight into dermatology education in the veterinary curriculum from the perspectives of both faculty and students in the United States and Indonesia.

This document provides information on the treatment options and prognosis for feline pemphigus foliaceus (PF), an autoimmune skin disease in cats. The document discusses the use of glucocorticoids, such as triamcinolone and prednisone, as well as non-glucocorticoid options like cyclosporine and chlorambucil. It emphasizes the importance of achieving disease remission and minimizing adverse effects. The document also mentions alternative treatments, such as topical steroids and oclacitinib, and highlights the need for further research in this area. The prognosis for cats with PF is generally good, but long-term therapy and relapses are common. Client education and support are important aspects of managing the disease.

IntroductionDermatological consultations represent a great part of the small animal medical clinic routine. Canine atopic dermatitis (CAD) is a common skin disease that affects a significant amount of dogs, making it a relevant consideration in clinical practice. The role of the endocannabinoid system on skin homeostasis has been described and its deregulation contributes to dermatopathies. Its function in specialized skin cells reveals an expressive therapeutic potential. Due to the difficulties and the growing scientific evidence of the therapeutic benefits of cannabis on animals, this work aimed to evaluate the anti-inflammatory effects of cannabis-derived oil in the treatment of CAD.MethodsFourteen canines diagnosed with CAD were divided into two groups: T: full spectrum high cannabidiol (CBD) cannabis oil, 2,5 mg/kg; and C: control group (treated with olive oil alone). The effectiveness was evaluated based on the degree of pruritus, dermatological evaluation (CADESI-4) and histopathological evaluation of the skin including mast cell count.ResultsDespite the theoretical basis, there were no significant results obtained between the compared treatments.DiscussionThus, it can be concluded that although full spectrum high cannabinoids therapy presents a promising approach to immunological diseases, further research is required in order to establish the actual effective cannabinoid ratio within the myriad possible combinations and for multi-target therapy of CAD.

Background: Allergic skin diseases are common in horses worldwide. The most common causes are insect bites and environmental allergens. Objectives: To review the current literature and provide consensus on pathogenesis, diagnosis, treatment and prevention. Materials and Methods: The authors reviewed the literature up to November 2022. Results were presented at North America Veterinary Dermatology Forum (2021) and European Veterinary Dermatology Congress (2021). The report was available to member organisations of the World Association for Veterinary Dermatology for feedback. Conclusions and Clinical Relevance: Insect bite hypersensitivity (IBH) is the best characterised allergic skin disease. An immunoglobulin (Ig)E response against Culicoides salivary antigens is widely documented. Genetics and environmental factors play important roles. Tests with high sensitivity and specificity are lacking, and diagnosis of IBH is based on clinical signs, seasonality and response to insect control. Eosinophils, interleukin (IL)‐5 and IL‐31 are explored as therapeutic targets. Presently, the most effective treatment is insect avoidance. Existing evidence does not support allergen‐specific immunotherapy (ASIT) using commercially available extracts of Culicoides. Hypersensitivity to environmental allergens (atopic dermatitis) is the next most common allergy. A role for IgE is supported by serological investigation, skin test studies and positive response to ASIT. Prospective, controlled, randomised studies are limited, and treatment relies largely on glucocorticoids, antihistamines and ASIT based on retrospective studies. Foods are known triggers for urticaria, yet their role in pruritic dermatitis is unknown. Recurrent urticaria is common in horses, yet our understanding is limited and focussed on IgE and T‐helper 2 cell response. Prospective, controlled studies on treatments for urticaria are lacking. Glucocorticoids and antihistamines are primary reported treatments. Background – Allergic skin diseases are common in horses worldwide.

Antimicrobial-resistant cutaneous infections are increasing in veterinary medicine. The use of systemic antibiotics should be limited to severe cases of pyoderma to decrease the microbial pressure and selection for multidrug-resistant bacteria. Topical antimicrobials with a low-resistance profile, such as chlorhexidine, benzoyl peroxide, and ethyl lactate have been used for decades in veterinary dermatology. However, new alternatives have been explored in the past decade. The goal of this review is to summarize the current knowledge on the antibacterial efficacy and clinical use, when reported, of "classic" and new treatment options for topically treating canine pyoderma. This review is intended to fill the gap from previous systematic reviews published in veterinary dermatology a decade ago. The studies reported in this review emphasize the need and desire for alternatives to the classic topical antimicrobials used in veterinary medicine to significantly reduce the use of systemic antibiotics in the spirit of appropriate antimicrobial stewardship.

Dermoscopy is a noninvasive, painless, easy‐to‐perform technique used in human and veterinary medicine for rapid and magnified in vivo observation of dermatological lesions and disease. Dermoscopy can lead to a swifter diagnosis and may eliminate the need to perform more invasive diagnostic testing such as skin biopsies. To perform dermoscopy, the clinician needs a dermoscope and a software program equipped with image capture for pattern identification. Two techniques exist for dermoscopy: standard contact, where the dermoscope is applied directly to the patient's skin with the use of a liquid interface, or noncontact, where there is no direct contact between the skin and the dermoscope. The most important criteria to be considered when using dermoscopy are the morphology/arrangement of vascular structures, scaling patterns, colours, follicular abnormalities and specific disease features. Application of dermoscopic findings should always be correlated with the patient's history, clinical signs and the morphology of the skin lesions. Dermoscopy does require an initial financial and time investment by the clinician, yet this technique can quickly and easily help to identify patterns of disease that correlate with clinical diagnosis of dermatological disease.

Local anaesthesia techniques are now essential parts of the multimodal analgesic approach applied in the care of small animals. The sensory innervation of the nose is provided by the maxillary division of the trigeminal nerve, so nasal pain can be prevented or alleviated by blocking branches of this nerve. Maxillary or infraorbital nerve block can be used if invasive procedures are performed on the nose of the canine and feline patients. Clear anatomical landmarks facilitate the placements of these blocks, which impose relatively low risk to the patients. These blocks do not require any advanced equipment and all necessary material is widely available in small animal veterinary practices. The total dose of the local anaesthetic agents should be calculated precisely to avoid toxicity. [ABSTRACT FROM AUTHOR]

Background: Human skin color, predominantly determined by the chromophores of melanin, hemoglobin, and exogenous carotenoids, is often measured to serve various medical and cosmetic applications. Although colorimetry has been used to evaluate the skin erythema in allergic dogs, the native canine skin color remains unknown. Methods: We measured the skin color in 101 healthy dogs using a calibrated optical system with a smartphone and a mobile dermatoscope DermLite DL1. The results were retrieved in the CIELAB color system and compared to the human color ranges. Results: The lightness (L*) of canine skin ranged from 28.5 to 78.3, which is slightly broader than that of human skin. There was a difference of 3.9 in redness (a*) between canine and human skin, but this variation could be attributed to the similarly valued colorimetric error of the optical system. Nonetheless, the skin yellowness was significantly different for dogs and humans (respective median b* of 12.3 versus 16.6, p < 0.01). This difference might be due to canids not being able to accumulate typically yellowish carotenoids. Furthermore, the native canine skin color did not exhibit a typical dependence between the coordinates of lightness (L*) and yellowness (b*), known as the individual typology angle, °ITA. Conclusion: We reported the first dataset of the native canine skin color in the CIELAB color space. We discovered a similarity in skin lightness and a difference in skin yellowness. However, further studies are needed for a more precise comparison of skin redness. [ABSTRACT FROM AUTHOR]

In dermatology practice, hair-loss along with pruritus represents a very common and challenging problem. Persistent or transient hair-loss is associated to a lot of skin disorders, being of secondary origin in the most cases. The evaluation of alopecic patient for diagnostic assessment should include a complete history, a general and dermatological examination followed by suitable tests. Among them, trichogram is recognized as an easy and fast aid for investigation of troubles in hair anatomy and hair growth. The present study describes some distinct trichography aspects from alopecic dogs, cats and buffaloes which were examined at Dermatology Service of Veterinary Medicine Faculty from Bucharest. In summary, trichogram offers a definitive diagnostic especially for parasitic, fungalassociated and self-induced alopecia, but also an indicative data for many other skin and hair disorders.

The article discusses the global challenges of climate change and biodiversity loss and their implications for the health sector, including veterinary dermatology. The health sector is both a significant emitter of greenhouse gases and affected by the health problems caused by climate change. Changes in temperature and precipitation can impact the prevalence and distribution of diseases, while biodiversity loss is driven by habitat destruction and pollution. The veterinary dermatology community has formed a group to address these issues and promote sustainable and climate-sensitive behavior in their profession. They also aim to support research on the impact of antiparasitic chemicals on biodiversity. The group welcomes anyone who wants to contribute to reducing their ecological footprint to join their project. [Extracted from the article]

Staphylococcus pseudintermedius is the most common cause of pyoderma in dogs. We validated a point-of-care (PoC) test based on colorimetric loop-mediated isothermal amplification (LAMP) for rapid S. pseudintermedius identification and susceptibility testing for first line antimicrobials for systemic treatment of canine pyoderma, i.e., lincosamides, first generation cephalosporins and amoxicillin clavulanate. Newly designed LAMP primers targeting clinically relevant resistance genes were combined with a previously validated set of primers targeting sps L for species identification. After laboratory validation on 110 clinical isolates, we assessed the performance of the test on 101 clinical specimens using routine culture and susceptibility testing as a reference standard. The average hands-on and turnaround times for the PoC test were 30 and 90 min, respectively. The assay showed sensitivity and specificity near 100% for both species identification and susceptibility testing when performed on bacterial cultures or clinical specimens in the laboratory. However, the PoC test yielded less accurate results when performed on-site by clinical staff (92% sensitivity and 64% specificity for species identification, 67% sensitivity and 96% specificity for β-lactam susceptibility, and 83% sensitivity and 71% specificity for lincosamide susceptibility). These results indicate that the PoC test should be adapted to a user-friendly technology to facilitate performance and interpretation of results by clinical staff. If properly developed, the test would allow veterinarians to gain rapid information on antimicrobial choice, limiting the risk of treatment failure and facilitating adherence to antimicrobial use guidelines in small animal veterinary dermatology. • A test was developed for direct antibiotic susceptibility testing on skin samples. • The average turnaround time for the assay was 90 min. • The test showed nearly 100% sensitivity and specificity in the laboratory. • Diagnostic accuracy was lower under field conditions.
