Background: The SCORing Feline Allergic Dermatitis scale (SCORFAD) is a validated dermatological scale assessing reaction patterns associated with allergic dermatitis in cats. While no pathognomonic reaction pattern is recognised with flea allergy dermatitis (FAD), miliary dermatitis is more common.

Hypothesis/objective: This study aimed to document regional cutaneous reaction patterns of cats with fleas using a modified SCORFAD (mSCORFAD).

The medical management of chronic canine pruritic dermatologic conditions is challenging and often frustrating. This is a report that shows one way of aiding the management of pruritic dogs using a remote monitoring device. It is often difficult for veterinarians to get dog owners to return to the clinic once a dog is treated.

Background: Disruptions in sleep and pain are frequent complaints following total knee arthroplasty (TKA). Perioperative sleep disturbances may lead to decreased pain tolerance as well as other consequences. The purpose of this study is to evaluate the effectiveness of self-guided meditation for improving sleep quality following TKA.

Historic data show that home flea infestations can be managed by treating all animals on the premises with a highly effective flea control product. The use of effective products has also been shown to reduce pruritus and minimize dermatologic lesions in both cats and dogs. Therefore, an in-home study was conducted in West Central Florida USA to evaluate the efficacy of a topically applied selamectin-sarolaner formulation to control fleas in naturally infested cats over a 12-week period.

Background: The purpose of this study was to determine the optimal window for collection of patient-reported outcome measures (PROMs) after total joint arthroplasty (TJA).

Methods: Our prospectively collected institutional joint registry was queried for patients who underwent primary, unilateral TJAs. The primary outcomes were the net changes in WOMAC, SF-12 MCS, SF-12 PCS, OHS, KSCRS, and UCLA activity rating system at 6, 12, and 24 months postoperatively.

Article Synopsis
  • A study in west central Florida evaluated the effectiveness of two flea control products, lotilaner (Credelio) and spinosad (Comfortis), on client-owned dogs to establish baseline efficacy and detect any future resistance.
  • Forty-four households were randomized to receive either treatment, and various assessments were conducted at multiple time points to measure flea counts and dermatological symptoms.
  • Results showed both products significantly reduced flea counts (over 99% reduction at Week 1) and improved skin condition scores, with lotilaner demonstrating lower flea counts than spinosad at Week 4.

Article Synopsis
  • A study in west central Florida evaluated the effectiveness of two flea control products, lotilaner (Credelio®) and spinosad (Comfortis®), on client-owned dogs to track and compare flea infestations and related dermatological signs over time.* -
  • The study involved 44 households where dogs were randomized to receive either product, with flea counts and skin condition assessments conducted at multiple time points, revealing significant reductions in flea populations after treatment.* -
  • Both treatments were highly effective, achieving over 99% flea count reduction within a week and maintaining a 100% flea-free status by Week 8, with the lotilaner group showing slightly better results at Week 4.*

Background: Squamous cell carcinoma (SCC) is the most commonly reported neoplasm of the nasal planum and treatment is focused on localized disease. Rostral maxillectomy and/or nasal planectomy are considered standard of care for excision of nasal planum SCC; however, the cosmetic outcome of these procedures can be deemed unacceptable by many pet owners.

Objectives: The study aim was to evaluate the efficacy of combination carbon dioxide (CO ) laser surgery and cryosurgery as a palliative treatment modality in dogs with nasal SCCs.

Article Synopsis
  • The Burkholderia cepacia complex (Bcc) is a rising cause of opportunistic infections in dogs, particularly those on immunosuppressive medications.
  • A study examined four dogs with Bcc-related dermatitis, highlighting diverse clinical symptoms and severe histopathological findings, including significant inflamed skin conditions.
  • Treatment varies, with most dogs responding to certain antibiotics, though one case developed severe sepsis and resistance, ultimately leading to euthanasia.

Article Synopsis
  • Fluralaner was found to be more effective than selamectin for controlling flea infestations in cats, achieving a 96.6% reduction in fleas within 7 days compared to 79.4% with selamectin.
  • At the end of a 12-week study, 100% of cats treated with fluralaner were flea-free, in contrast to only 38.5% of those treated with selamectin.
  • Additionally, 95% of homes with fluralaner-treated cats experienced complete flea eradication, significantly higher than the results observed in homes treated with selamectin.

Background: An in-home investigation of naturally flea infested dogs was conducted in West Central Florida, USA to evaluate and compare the effectiveness of two different oral flea adulticides to control flea infestations, minimize dermatologic lesions and reduce pruritus over an 8-week period.

Methods: Twenty-nine dogs living in 19 homes and another 26 dogs residing in 16 different homes were orally administered either a sarolaner or spinosad chewable, respectively on day 0 and once between days 28-30. Products were administered by study personnel according to label directions.

Background: A study was conducted to evaluate and compare the effectiveness of two different oral flea and tick products to control flea infestations, reduce pruritus and minimize dermatologic lesions over a 12 week period on naturally infested dogs in west central FL USA.

Methods: Thirty-four dogs with natural flea infestations living in 17 homes were treated once with a fluralaner chew on study day 0. Another 27 dogs living in 17 different homes were treated orally with an afoxolaner chewable on day 0, once between days 28-30 and once again between days 54-60.

The purposes of this study were to determine whether the storage mite, Tyrophagus putrescentiae, could survive and thrive on dog food and if mould growth was important to their survival. All of the chambers (n = 42) were started with 10 female mites and evaluated every other day for mite survival and for the spontaneous development of mould. Ten chambers tested the effect of low moisture on mite survival.

The moth genus Nemoria (Lepidoptera: Geometridae) includes 134 described species whose larvae and adults display a considerable range of phenotypic plasticity in coloration and morphology. We reconstructed the phylogeny of 54 species of Nemoria and seven outgroups using characters from the mitochondrial genes, Cytochrome Oxidase I and II (COI and COII), and the nuclear gene, Elongation Factor-alpha (EF-1alpha). Maximum parsimony, maximum likelihood and Bayesian inference were used to infer the phylogeny.
