OBJECTIVE To describe and evaluate outcomes of a multidisciplinary, minimally invasive approach combining lacrimoscopy and fluoroscopically guided stenting for management of nasolacrimal apparatus (NLA) obstruction in dogs.

DESIGN Prospective, nonrandomized clinical trial.

ANIMALS 16 client-owned dogs with confirmed NLA obstruction.

PROCEDURES Dogs underwent CT contrast dacryocystorhinography, rhinoscopy, and lacrimoscopy. Whenever possible, the NLA was stented, typically with fluoroscopic guidance.

RESULTS Median duration of clinical signs prior to treatment was 3.2 months (range, 0.2 to 14 months). Causes of NLA obstruction were a foreign body (n = 5), dacryocystitis (4), stenosis secondary to fibrosis (3), granulation tissue (1), or granulation tissue in association with a small foreign body (1); a cause was not identified in 2 dogs. Stents were placed in 14 of 16 (88%) dogs for a median duration of 5.6 weeks (range, 1.3 to 9.4 weeks). Stenting was not possible in 2 dogs with stenosis of the NLA secondary to granulation tissue or fibrosis. Owners of all 16 dogs reported at least 60% clinical improvement with median improvement rated as 95%, and owners of 8 dogs reporting complete resolution of signs. Two dogs required antimicrobial administration because of dacryocystitis that persisted after stent removal; a foreign body was not found in either dog.

CONCLUSIONS AND CLINICAL RELEVANCE Overall clinical response and owner-rated improvement for dogs with NLA obstruction that underwent lacrimoscopy and fluoroscopically guided stenting were high, especially given that these dogs had failed to respond to conventional treatment.

OBJECTIVE To evaluate outcomes for cats treated with orally administered famciclovir 3 times/d for clinical signs attributed to naturally occurring feline herpesvirus type 1 (FHV-1) infection and to assess variables related to owner satisfaction with the treatment.

DESIGN Retrospective case series.

ANIMALS 59 client-owned cats.

PROCEDURES Medical records were reviewed to identify cats treated for presumed FHV-1 infection from 2006 through 2013 with ≥ 1 follow-up visit. Signalment, duration of clinical signs, prior treatment, examination findings, diagnostic test results, concurrent treatments, and outcome data were recorded. Owners were asked to complete a survey regarding patient- and treatment-related variables. Data were compared between cats that received low (approx 40 mg/kg [18 mg/lb]) and high (approx 90 mg/kg [41 mg/lb]) doses of famciclovir, PO, 3 times/d.

RESULTS Patient age ranged from 0.03 to 16 years. Conjunctivitis (51/59 [86%]), keratitis (51 [86%]), blepharitis (19 [32%]), nasal discharge or sneezing (10 [17%]), and dermatitis (4 [7%]) were common findings. Clinical improvement was subjectively graded as marked in 30 (51%) cats, mild in 20 (34%), and nonapparent in 9 (15%). Median time to improvement was significantly shorter, and degree of improvement was significantly greater in the highdose group than in the low-dose group. Adverse effects potentially attributable to famciclovir administration were reported for 10 cats. On the basis of survey responses, most (29/32 [91%]) owners were satisfied with their cat's treatment.

CONCLUSIONS AND CLINICAL RELEVANCE Famciclovir at the prescribed dosages was associated with improved clinical signs in cats with presumed FHV-1 infection, and few adverse effects were attributed to the treatment. Further studies are needed to assess whether a famciclovir dosage of 90 versus 40 mg/kg, PO, 3 times/d would result in increased efficacy and shorter treatment time.
