RESUMEN

OBJECTIVE: Effect of photobiomodulation therapy (PBMT) in patients with CCLR after TPLO surgery by measuring C-reactive protein (CRP), percentage weight bearing, lameness using a short form of a composite measure pain scale, evaluated by the clinician and owners, and surgical site infection. SAMPLE: 54 client-owned dogs with CCLR undergoing unilateral TPLO surgery were enrolled in this study between April 5, 2021, through April 10, 2022. METHODS: The study population was randomly assigned to either a treatment group receiving PMBT (24 dogs) or a control group (30 dogs). PMBT was performed on the treatment group immediately after induction, and 6 hours, 24 hours, 48 hours, and 8 weeks postoperatively. The control group received sham PMBT (device turned off) at the same time. Evaluation of CRP, CMPS-SF, evidence of SSI, and %WB were evaluated for all dogs 24 hours preoperatively, and then 24 hours, 48 hours, and 8 weeks postoperatively. Owners completed CMPS-SF and subjective evaluations weekly for 8 weeks postoperatively. RESULTS: No statistically significant differences were found between treatment groups when evaluating CRP, %WB, and CMPS-SF by the clinician and weekly evaluation of the CMPS-SF by owners. Although no statistically significant differences were found in patients developing surgical site infections between treatment groups, SSI was only observed in patients in the control group (5/30, 16.6%). Most were minor/superficial infections (4/30 13.3%), and a single dog (1/30, 3.3%) had a major/deep surgical site infection. CLINICAL RELEVANCE: Although with promising but not statistically significant differences between groups, surgical site infections may be reduced after PBMT application.

RESUMEN

Persistent socket pain is a condition described in humans after enucleation of the eye. This report aims at describing this condition in dogs. A 10-year-old male-neutered crossbreed was presented to the referral veterinary surgeon for enucleation of the right ocular globe. Anaesthesia and surgery were uneventful although during the postoperative period the dog was reluctant to open the mouth and to be explored by the referral veteterinary surgeon. Despite treatment with meloxicam, paracetamol and tramadol, no improvements were observed. Ten weeks after surgery, the dog was referred to the Dick White referrals for further investigations. Ophthalmic examination was normal, though palpation of the wound triggered an avoidance response. Magnetic resonance imaging showed changes compatible with orbital cellulitis. The area of interest was evaluated with the use of the mechanical Von Frey filaments. A response, characterised by sudden turning of the head and attempts to withdraw it, was evoked with filament 4.93 (8.0 g) during stimulation of the periorbital area. After induction of anaesthesia, an ultrasound-guided injection containing levobupivacaine 0.5% and methylprednisolone was performed within the retrobulbar area. Three hours after recovery from anaesthesia, no discomfort was observed during palpation of the area. Re-evaluation was performed with the Von Frey filaments; no response could be evoked during testing with all 20 filaments (from 2.36 to 6.65) applied on either side of the face. The patient was discharged with a course of gabapentin and, 3 weeks after the intervention, the dog showed no clinical signs of pain. Persistent socket pain is an unpleasant sensation at the level of the enucleated orbit, and it should be regarded as a challenging condition to diagnose and treat. The MRI findings appeared to be essential to select the most appropriate interventional treatment. The injection of local anaesthetic and steroid into the retrobulbar space was useful for both confirming the diagnosis and treating pain by reducing the peripheral signalling and decreasing the residual inflammation.

RESUMEN

A 10-week-old male, Xoloitzcuintle (Mexican hairless dog), weighing 8.9 kg was presented after its owner accidentally stepped on its paw. The dog presented with acute pain, inflammation and grade IV lameness in the right hind paw. A complete transverse fracture in the right proximal tibia was diagnosed from radiography. The dog underwent a minimally invasive plate osteosynthesis (MIPO) procedure. After surgery, photobiomodulation therapy combined with static magnetic field (PBMT-sMF) was applied twice daily for 21 days. A multi-wavelength PBMT-sMF device was applied at three sites using different frequencies: proximal and distal of the fracture zone (3000 Hz, 40.35 J per site, and 300 s per site) and in the fracture zone (250 Hz, 39.11 J and 300 s per site). Follow up radiographies were performed after surgery and treatment with PBMT-sMF. Eighteen days post-surgery the healing process of bone was advanced. Fifty-five days post-surgery the callus was enlarged. In addition, radiographic union and clinical union was evidenced by closure of the fracture gap. This case report has reported the use of PBMT-sMF in order to accelerate and improve bone healing following a MIPO procedure on a complete transverse fracture in the proximal tibia of a puppy.

RESUMEN

The objective of this report is to describe the use and outcome of stereotactic body radiation therapy (SBRT) for treatment of pheochromocytomas in 8 dogs. Pheochromocytomas are an uncommon but challenging tumour to manage. Adrenalectomy is the standard of care for treatment of pheochromocytomas in both animals and humans; however, unpredictable catecholamine secretion from the tumour and vascular and local invasion of the tumour and thrombi can pose life-threatening perioperative and anaesthetic risks. SBRT has been investigated as an alternative to adrenalectomy in human patients with pheochromocytomas. Eight dogs with clinical signs, an adrenal mass, and cytology and/or urine normetanephrine/creatinine ratios consistent with pheochromocytoma were treated with SBRT in lieu of adrenalectomy. Three dogs presented with acute hemoabdomen. Seven dogs had caval tumour invasion, 3 with extension into the right atrium. Following SBRT, all dogs had complete resolution of clinical signs and reduced urine normetanephrine/creatinine ratio and/or tumour size. No significant anaesthetic complications were encountered. Acute radiation toxicity was limited to grade I gastrointestinal signs in 3 dogs and resolved within 1-2 days of symptomatic therapy. Five of 8 dogs were alive at the time of follow up, with a median follow up time of 25.8 months. SBRT resulted in a favourable outcome and mitigated the life-threatening risks of adrenalectomy in these 8 dogs. SBRT may be a safe and effective alternative to adrenalectomy for pheochromocytomas in dogs with non-resectable tumours, or for owners averse to the risks of surgery.

RESUMEN

A 5-week-old male intact Golden Retriever puppy was presented for a history of vomiting and diarrhea with hematochezia. Ultrasound findings confirmed the presence of an ileocecocolic intussusception. Surgical correction was declined because of financial concerns. Based on a pediatric procedure used in humans, an ultrasound-guided hydrostatic reduction (USGHR) was performed. This procedure consisted in injecting saline rectally under controlled pressure to mechanically reduce the intussusception. Reduction of the intussusception and evaluation of potential complications were concurrently evaluated by ultrasound during the procedure. No recurrence was observed the next day and the puppy was discharged. Follow-up indicated that the dog was still doing well 6 months later. This case report describes a new technique in veterinary medicine allowing successful nonsurgical reduction of an ileocecocolic intussusception in a dog. This procedure is innovative, simple, and substantially decreases the cost and minimizes morbidity potentially associated with surgical management.

RESUMEN

OBJECTIVE: To evaluate the effects of ileocecocolic junction (ICJ) resection on gastrointestinal signs, biochemical parameters, and nutritional variables in dogs and cats. ANIMALS: 20 dogs and 15 cats that underwent ICJ resection between January 2008 and June 2020. PROCEDURES: Medical records of dogs and cats that underwent ICJ resection were reviewed, and clinical signs, laboratory abnormalities, and nutritional information were obtained. Additional follow-up information was obtained by contacting primary care veterinarians or owners. A subset of dogs (n = 6) and cats (2) were evaluated in the hospital via clinical examination, clinicopathologic testing, nutritional testing, and abdominal ultrasound. RESULTS: Twenty dogs and 15 cats underwent resection of the ICJ for treatment of a variety of conditions. Ten of 20 dogs (50%) and 11/15 cats (73%) were reported by their owners to have a good long-term outcome based on the lack of long-term gastrointestinal signs or the ability to control gastrointestinal signs with diet and supplements alone. Despite owner-reported good outcomes, long-term diarrhea, weight loss, and muscle loss were common. Of the 6 dogs evaluated in the hospital, 3/6 (50%) had muscle loss, 2/6 (33%) had low taurine concentrations, and 1 dog each had low cobalamin, folate, 25-hydroxyvitamin D, and ionized calcium. Neither of the 2 cats evaluated in the hospital had nutritional abnormalities identified. CLINICAL RELEVANCE: Owners should be informed of the possibility of long-term gastrointestinal clinical signs and the potential need for long-term nutritional management after ICJ resection.

RESUMEN

Advancements within the field of veterinary surgical oncology are constantly presenting themselves, especially with continued development of comprehensive cancer programs. With the use of more advanced imaging techniques within veterinary medicine, tumor staging is improving and techniques novel to veterinary medicine are being evaluated for potential clinical application. Recommended tumor staging and treatment approach for apocrine gland anal sac adenocarcinoma in dogs has evolved, with the anticipation of good long-term patient outcomes. Preoperative staging for mast cell tumors and recommendations for surgical margins to obtain for wide surgical excision is being reassessed by surgeons.

RESUMEN

BACKGROUND: Eyelid mass removal and cryotherapy application using only local anaesthesia and restraint may benefit patients with high anaesthesia risks. OBJECTIVE: To evaluate and validate cryosurgery application using the CryoPen XL® on palpebral masses under local anaesthesia for patients not suitable for general anaesthesia. METHODS: Thirty patients underwent the procedure between November 2015 and April 2020. The procedure steps were as follows: skin preparation and local anaesthesia of the affected eyelid; debulking by resection and/or squeezing out the inspissated material; cryosurgery and post-operative care using topical medication, antibiotics and anti-inflammatory ointment. The medical records of the patients who underwent the operation were evaluated. Moreover, a telephonic survey with the pet owners was performed to determine recurrence, time to recurrence, survivability and side effects. RESULTS: Among the 30 owners, 29 responded to the survey. Ten (10/38, 26.3%) masses recurred with an average time to recurrence of 6.0 months. The estimated average depths for all, non-recurred, and recurred masses were 1.89, 1.88 and 1.90 mm, respectively. The average recurrence rate and time to recurrence were higher and earlier, respectively, than previously reported values. However, no patient presented intra- or post-operative complications. CONCLUSION: These findings suggest that local anaesthesia and cryosurgery using the CryoPen XL® can be used in patients with eyelid masses who are not suitable for general anaesthesia. Compared with the surgical eyelid mass removal and blepharoplasty procedure, the reported procedure is time- and cost-effective, with the additional benefit of not requiring general anaesthesia.

RESUMEN

OBJECTIVES: Hydrotherapy is a common part of the postoperative care after surgical treatment of thoracolumbar intervertebral disc extrusion in dogs. There are currently no guidelines on when to commence hydrotherapy after surgery. Early hydrotherapy may be associated with an increased risk of postoperative complications including surgical site infection and neurological deterioration. The goal of this study was to report the prevalence and types of postoperative complications in dogs receiving early hydrotherapy. MATERIALS AND METHODS: Eighty-three dogs commencing hydrotherapy within 5 days after surgical treatment for thoracolumbar intervertebral disc extrusion were included in a retrospective descriptive study. All postoperative complications were recorded. RESULTS: Ten minor and 16 major complications were recorded in a total of 26 dogs. The majority of recorded complications were unlikely, but not excluded to be, caused by the initiation time of hydrotherapy. One dog developed a surgical site infection and one dog had a confirmed further extrusion of the originally operated intervertebral disc, which may have been influenced by early initiation of hydrotherapy. CLINICAL SIGNIFICANCE: Early hydrotherapy is possibly associated with occurrence of postoperative complications. Associations between the reported complications and early hydrotherapy, and possible benefits of early hydrotherapy, need to be further investigated before early initiation of hydrotherapy can be recommended.

RESUMEN

OBJECTIVE: To retrospectively compare the efficacy and duration of effect of three commonly used locoregional blocks in dogs undergoing pelvic limb orthopaedic surgery. STUDY DESIGN: Retrospective clinical study. ANIMALS: A total of 236 dogs that underwent pelvic limb surgery and were administered a locoregional technique. METHODS: A total of 236 hospital records were reviewed and 230 included in statistical analysis. Dogs were grouped as following: electrostimulation-guided pre-iliac femoral and sciatic nerve block (group PFS, n = 70); ultrasound-guided saphenous and sciatic nerve block (group SS, n = 76); or lumbosacral epidural (group EPI, n = 84). In group EPI, bupivacaine 0.5% or ropivacaine 0.75% was used with morphine. Dogs were pain scored (short form of the Glasgow Composite Measure Pain Scale) hourly following recovery from anaesthesia. Analysed data included: time to first postoperative dose of methadone, pain score at that time, intraoperative rescue analgesia, intraoperative hypotension and ability to walk and urinate overnight. Separate analyses were performed including all pelvic limb surgeries and including only elective stifle surgeries. Kruskal-Wallis and Mann-Whitney tests were performed. A p value < 0.05 was considered significant. The median (range) is reported. RESULTS: For all pelvic limb surgeries, the time to first postoperative methadone was 530 (110-1337), 440 (140-1030) and 466 (135-1094) minutes in groups EPI, PFS and SS, respectively, and was not significantly different. Postoperatively, 10/84, 15/70 and 12/76 dogs in groups EPI, PFS and SS, respectively, did not require methadone (nonsignificant). Significantly fewer dogs in group EPI (18%) required intraoperative rescue analgesia compared with group SS (38%), but not compared with PFS (30%). Significantly more dogs in group EPI had hypotension intraoperatively (30%) and urinary retention postoperatively (62%). CONCLUSIONS AND CLINICAL RELEVANCE: Intraoperative analgesia may be superior with EPI than SS for some surgeries of the pelvic limb, but not for stifle surgeries. All three techniques provided similar requirement for postoperative analgesia, but EPI caused higher incidence of intraoperative hypotension and postopertive urinary retention.

RESUMEN

The aim of this study was to investigate the analgesic efficacy of a preoperative acupuncture treatment in 24 client-owned dogs undergoing thoracolumbar hemilaminectomy. Dogs were randomly assigned to either group A (Acupuncture) or group C (Control). Before skin incision, group A was treated with acupuncture, performed under general anaesthesia for 30 min. Rescue intraoperative fentanyl was administered following a 20% increase in cardiovascular parameters compared to baseline values, measured before incision. An observer masked to the treatment assessed pain, pre- and postoperatively, with the Glasgow (GCPS), the Colorado (CPS) pain scales and a Visual Analogue Scale (VAS); additionally, the mechanical thresholds (MT) were measured with the Electronic von Frey Anaesthesiometer (EVF) at four points located near the herniated disc. The groups were compared with respect to intraoperative cardiovascular and respiratory variables, rescue fentanyl administered in total and at different surgical events (first incision [FI], drilling [DR], disc removal [RE] and skin suturing [ST]), and pre- and postoperative pain scores and MT. Group A received less fentanyl than group C (P = 0.014); this difference was significant at FI P = 0.035) and RE (P = 0.004). The improvement in postoperative CPS score (P = 0.013), VAS score (P = 0.003) and MT (P = 0.001) compared to preoperative values was greater for group A than for group C, whereas the treatment assignment had no effect on postoperative changes in GCPS compared to baseline. Pre-operative acupuncture may help improving perioperative analgesia in dogs with intervertebral disc herniation undergoing thoracolumbar hemilaminectomy.

RESUMEN

OBJECTIVE: To describe 4 Great Danes with colonic torsions and describe the risk of torsion recurrence in this breed, which has not previously been reported. This study also describes pneumocolon as a rapid and noninvasive diagnostic for confirmation of colonic torsion. SERIES SUMMARY: Four Great Danes were presented with nonspecific gastrointestinal (GI) clinical signs. Colonic torsion was diagnosed in each case with either plain radiography identifying pneumocolon or contrast radiography (barium enema). Bloodwork in each case revealed nonspecific changes. Each case had a previous gastropexy, 3 of which were prophylactic and 1 as a surgical emergency for gastric dilatation-volvulus. Three cases had favorable outcomes with emergency surgical intervention and returned to normal activity levels with resolution of clinical signs. Two cases of colonic torsion recurred, 1 of which occurred subsequent to a prior left-sided colopexy. One case of recurrence had persistent clinical signs following surgical revision and was euthanized. NEW OR UNIQUE INFORMATION PROVIDED: This is the first report describing pneumocolon to identify a colonic torsion, providing a rapid and low-morbidity diagnostic aid and to describe the recurrence of colonic torsion in 2 dogs. Support to a previous hypothesis for an association between colonic torsion and altered GI motility is provided. Prior publications reporting colonic torsion and entrapment in German Shepherd Dogs associated with disruption of the duodenocolic ligament reported no recurrence following correction without colopexy. The recurrence in these 2 dogs suggests colonic torsion in Great Danes may represent a different or more severe form of this condition.

RESUMEN

Alternative treatments to surgery in canine degenerative lumbosacral stenosis (DLSS) remain limited and reliable predictors of outcome are lacking. The aims of this clinical trial were threefold: to assess the usefulness of single epidural steroid injection (ESI) in DLSS, to compare the outcomes of ESI and decompressive surgery, and evaluate ESI as a predictor of outcome following decompressive surgery. Dogs diagnosed with DLSS were prospectively recruited and administered an ESI. If clinical signs persisted or relapsed, decompressive surgery was recommended. Follow-up was obtained. Thirty-two dogs underwent ESI with 17 having subsequent surgery. Improvement after ESI was seen in 27/32 dogs (84.4%), with 17/22 (77.2%) relapsing within 6 months (n = 15/17 relapsing within 2 months). Five dogs failed to respond to ESI and another five (15.6%) presented a persistent post-ESI favourable response (mean follow-up time, 9.4 months). Post-surgical improvement occurred in all dogs. Outcome appeared more favourable following surgical decompression, with a trend towards reduced pain, increased mobility, and greater quality of life score. This study was unable to demonstrate that ESI could predict surgical outcome. ESI was confirmed as an effective treatment in most but not all cases, leading to transient alleviation of clinical signs for longer than previously reported. ESI provided a complete and apparently long-term sustained resolution of clinical signs in a subset of dogs. Despite this, there was indication that surgical decompression can lead to a more favourable outcome. Epidural steroid injection has a role in the management of DLSS dogs, particularly when surgery is not an option.

RESUMEN

BACKGROUND: Recent studies have reported contrasting results of the effects of laser therapy on post-operative intervertebral disk herniation, with a lack of evidence-based advantages of this modality within a rehabilitation protocol. The aim of this study was to report the clinical effects of photobiomodulation therapy within a post-operative rehabilitation protocol in dogs submitted to surgery for thoracolumbar disk extrusion. Twenty-four dogs were included in the study (12 dogs treated with laser therapy and rehabilitation protocol and 12 dogs treated with same rehabilitation protocol but without laser therapy). RESULTS: All dogs treated with laser therapy showed improved neurological status (Modified Frankel Score more than 3 within 30 days of physiotherapy starting) if deep nociception on admission was maintained (P = 0.04). However, Kaplan-Meier analysis did not show any statistical difference in time to regain ambulatory ability, although there was a tendency for a shorter mean time of 14.2 ± 8.55 days in the laser group versus 24 ± 18.49 days in the no laser group. CONCLUSIONS: The use of laser therapy in the post-operative rehabilitation of dogs affected by intervertebral disc extrusion and submitted to surgery for spinal decompression could help improve their neurological status.

RESUMEN

A qualitative survey was electronically distributed to practicing veterinarians in the state of Missouri to evaluate the frequency of use and economic impact of low-level laser therapy (LLLT) for the treatment of osteoarthritis (OA) in dogs in Missouri. The survey response rate was 10% (89/867). Approximately half (43%) of respondents had LLLT units, of which all used LLLT for OA treatment in dogs. In respondents without LLLT units, 20% referred patients for LLLT OA treatment. Training was most often obtained in-house by a representative of the LLLT unit manufacturer (76%). Treatment dose was largely unknown and chosen by predetermined settings on the LLLT unit (65%). In the majority of patients (84%), no treatment site preparation was performed. An average of four patients with OA were treated per wk with an average cost per treated joint of $28 (range: $15-45). This study provides insight into the current clinical use and estimated annual economic impact ($6.2 million per year) of treating a single OA joint in dogs with LLLT by Missouri veterinarians. The frequency with which LLLT is used in the treatment of OA combined with the variation in training and treatment protocols supports the need for further research regarding the application and efficacy of LLLT in dogs with OA.

The use of hyperbaric oxygen therapy (HBOT) is an accepted method of supporting wound healing in human medicine. Yet, because of the risk of complications associated with HOBT, a safer modification of the therapy, known as L-HOBT (lower pressure and lower oxygen concentration), is increasingly used nowadays. Therefore, due to the lack of literature reports regarding the clinical use of L-HBOT in animals, the authors decided to present the results of L-HBOT supportive treatment of postoperative wounds after hemimastectomy compared to classic treatment. The study group included 12 bitches divided into two groups: group A (assisted L-HBOT) and group B (classic treatment). In addition to conventional treatment, the supportive therapy included 1.5 hours of hyperbaric chamber therapy for 5 consecutive days, starting 24 hours after surgery (1500hPa pressure and 26% oxygen concentration in the chamber). The patients were followed and evaluated throughout the course of the treatment by two independent doctors. The results of the treatment revealed no negative clinical impact of L-HOBT supportive therapy on the body of the animals. At the same time, postoperative wounds after L-HOBT healed faster and with fewer postoperative complications compared to the control group. This resulted in a shorter treatment period, terminating with an earlier skin suture removal.

RESUMEN

BACKGROUND: Gallbladder mucoceles (GBM) typically are treated by cholecystectomy. Medical management rarely has been reported and medical and surgical management have not been compared. HYPOTHESIS/OBJECTIVES: To compare survival of dogs treated for GBM by medical management or cholecystectomy or both. ANIMALS: Eighty-nine client-owned dogs diagnosed with GBM that received cholecystectomy or medical treatment or both from 2011 to 2017. METHODS: Potential cases were identified by searching the medical records database. Data collected included signalment, clinicopathologic results, treatments, and ultrasonographic images and reports. Dogs were grouped according to the treatment received (medical management, surgical treatment, or both) that was chosen at the discretion of the attending veterinarian. Survival analysis was performed and prognostic variables identified and compared between treatment groups. RESULTS: Of dogs surviving at least 14 days after diagnosis, median survival times were 1802 (95% confidence interval [CI], 855-not reached) days, 1340 (95% CI, 444-1340) days, and 203 (95% CI, 18-525) days, for the surgical, medical, and medical then surgical treatment groups, respectively, and differed significantly (P < .0001). Gallbladder mucocele type (P = .05), serum alkaline phosphatase activity (P = .0001), and serum creatinine (P = .002) and phosphorus (P = .04) concentrations were associated with decreased survival across groups. Suspicion of biliary rupture on abdominal ultrasound (AUS) examination was correlated with increased survival in the surgical group (P = .02). CONCLUSIONS AND CLINICAL IMPORTANCE: Cholecystectomy for the treatment of GBM results in the best long-term survival in dogs surviving the immediate postoperative period (14 days) compared to medical management. Although medical management is associated with shorter survival compared to surgical treatment, it is a reasonable alternative when surgery cannot be pursued.

RESUMEN

Background: Proptosis is a serious traumatic disease commonly affecting small breed dogs and possibly causing loss of vision, with globe replacement surgery (GRS) being essential in most of the cases after stabilizing the patient's condition. Aim: To determine the common dog breeds and clinical findings associated with traumatic proptosis and demonstrate the short-term complications following GRS. Methods: The study was performed on 15 client-owned small-breed dogs presented with unilateral traumatic proptosis. Dogs were examined at initial presentation to determine the concurrent abnormalities associated with globe prolapse. The globe was replaced within the orbit and avulsed extraocular muscles were identified and sutured. Endoscopic examination of the ocular fundus was achieved 1 and 3 weeks after GRS in one Pekingese diagnosed with glaucoma. Complications following GRS were recorded. Results: Pekingese (53.3%) and Griffon (26.7%) were the most affected dogs with proptosis in Egypt. Bruised, hyperemic and swollen conjunctiva and periorbital tissue, lateral globe retraction, cloudy cornea, and miosis were common clinical findings associated with proptosis. Exposure keratitis, keratoconjunctivitis sicca, and exotropia were identified in all 15 patients at presentation. Complications following GRS included phthisis bulbi (53.3%), strabismus (26.7%), and lateral exotropia (20%). Intraocular pressure was reduced to 22 mmHg 3 weeks after GRS in the only patient diagnosed with glaucoma, and endoscopic evidence of optic nerve cupping was identified. Conclusion: Clinical findings associated with proptosis at initial presentation may have influenced the outcome of GRS. Favorable prognosis may be given to patients with relatively high potential for vision at initial presentation and ≤2 extraocular muscle avulsions. Immediate surgical intervention following the occurrence of proptosis should be advised to achieve favorable disease prognosis.

RESUMEN

CASE DESCRIPTION A 2.5-year-old 12-kg (26.4-lb) castrated male Miniature American Shepherd was referred because of a 3-week history of a localized crusted skin lesion on the digital pad of digit 3 of the right hind limb. CLINICAL FINDINGS Skin lesions were noted on the digital pads of the right hind limb. Serum biochemical analyses indicated severe hypercholesterolemia and hypertriglyceridemia. Ultrasonography of the terminal portion of the aorta and other major arterial vessels revealed substantial arteriosclerotic change. TREATMENT AND OUTCOME Medical treatments included administration of atorvastatin calcium, a low-fat diet, and omega-3 fatty acids to reduce serum lipids concentration; clopidogrel to prevent thrombosis; pentoxifylline to improve microcirculatory blood flow; clomipramine hydrochloride and trazodone hydrochloride to help with the behavioral problems; and gabapentin to help with pain management and behavioral problems. Surgical management included amputation of the initial digit involved, then eventually the entire initial limb involved. The response to treatment was poor, and euthanasia was elected. Postmortem findings revealed severe, widespread, and chronic intimal atherosclerosis; mild, widespread, and degenerative changes in the cerebral cortex; and edema and vascular congestion in the meninges. CLINICAL RELEVANCE To the authors' knowledge, this was the first report of skin necrosis secondary to atherosclerosis in a dog. Although the incidence of atherosclerosis has been considered very low in dogs, it should be investigated in dogs with severe hyperlipidemia. Primary hyperlipidemia has not been previously described in Miniature American Shepherd dogs but was the suspected underlying metabolic disorder.

RESUMEN

OBJECTIVE: To determine the effects of low-level laser therapy (LLLT) on clinical outcomes in dogs with cranial cruciate ligament disease treated with tibial plateau leveling osteotomy (TPLO). STUDY DESIGN: Randomized, placebo-controlled clinical trial. Owners and surgeons (care providers and assessors) were masked. ANIMALS: Ninety-five dogs were admitted for TPLO and assigned to 1 of 2 groups, laser group (LG; n = 51) or placebo group (PG; n = 44). METHODS: Three treatments (laser or placebo) were administered within a 4-day perioperative period. A fourth treatment was recommended and was accepted in 28.4% of cases (LG, n = 14; PG, n = 13). Dogs in the LG group received laser at wavelengths 660 nm red (100 mW) and at 800, 905 and 970 nm infrared (maximum 15 W continuous wave, 20 W peak pulsed wave), administered simultaneously. Dogs in the PG group received placebo laser (660 nm, 4 mW). Other treatments were identical. Outcomes were measured by difference in clinical metrology instruments (Liverpool Osteoarthritis in Dogs and adjusted Canine Orthopedic Index [COI]), osteotomy healing on a radiographic scale, time to cessation of nonsteroidal anti-inflammatory drug administration, and wound healing by owner questionnaire. RESULTS: The only difference detected between groups consisted of a greater improvement in the gait section of the adjusted COI (ACOI) in the LG group (median [interquartile range; IQR] = 6 [4-7.5]) compared with the PG group (median [IQR] = 4 [2-6]; P < .05). CONCLUSION: The laser protocol used in this study was associated with a greater improvement in ACOI gait in dogs treated with TPLO but did not improve any other clinical metrology instrument scores or bone healing. CLINICAL SIGNIFICANCE: This study provides some evidence that LLLT may improve the gait of dogs recovering from a TPLO, as assessed by owners.
