Long-term results of upper respiratory syndrome surgery and gastrointestinal tract medical treatment in 51 brachycephalic dogs

OBJECTIVES: After a first clinical study showing a high prevalence of gastrointestinal tract diseases in brachycephalic dogs presented for upper respiratory syndrome, a prospective study was performed to determine the influence of medical treatment for gastrointestinal tract disorders associated with upper respiratory syndrome surgery. METHODS: The gastrointestinal tract and respiratory disorders of 61 brachycephalic dogs presented for upper respiratory syndrome were evaluated. Together with surgery of the upper respiratory tract, a specific gastrointestinal medical treatment was administered. A minimal follow-up of six months was required for inclusion. RESULTS: Palatoplasty with rhinoplasty was the most common surgical correction (88.5 per cent). The mortality rate in the perioperative period was 3.3 per cent. Minor complications accounted for 26.2 per cent of cases. No aspiration pneumonia was encountered. A sufficient follow-up was obtained in 51 dogs. The improvement was judged by the owners as excellent or good in 88.3 per cent of the respiratory disorders and in 91.4 per cent of the gastrointestinal disorders. Clinically, a statistically significant improvement was obtained for both respiratory and gastrointestinal disorders. CLINICAL SIGNIFICANCE: In comparison with other studies, digestive tract medical treatment combined with upper respiratory surgery seems to decrease the complication rate and improve the prognosis of dogs presented for upper respiratory syndrome.     

Granulomatous giant cell submandibular sialadenitis in a dog

A 4-month-old dog was presented with a progressive swelling of the submandibular area. The history, course, cytological, and sialographic findings were consistent with an aseptic pyogranulomatous sialadenitis with concurrent duct blockage. This rare entity, responsive to medical treatment, appears to be similar to the granulomatous giant cell sialadenitis of humans.     

Uveodermatologic syndrome in a rat terrier

A 4 yr old intact male rat terrier presented with severe bilateral nonresponsive panuveitis. Bilateral uveitis, blepharospasm, conjunctival hyperemia, diffuse corneal edema, peripheral bullous retinal detachment, and secondary ocular hypertension were noted. Ocular lesions progressed despite aggressive medical treatment and were followed by cutaneous depigmentation and crusting along the nasal planum. Intensive oral and topical anti-inflammatory and topical antiglaucoma medications were administered, but the ocular disease progressed. A bilateral enucleation was performed. Uveodermatologic syndrome was diagnosed from histopathologic examination of a skin biopsy as well as histopathology of both globes after bilateral enucleation. To maintain control of the dermatologic lesions, oral azathioprine was initiated, but it was not well tolerated by this patient. Immunosuppressive doses of oral cyclosporine and anti-inflammatory doses of oral prednisone were used to control the depigmentation and crusting skin lesions.     

Traumatic corneal laceration with associated lens capsule disruption: a retrospective study of 77 clinical cases from 1999 to 2009

Objective Examine prognostic factors that may indicate when surgical lens removal is indicated to prevent vision‐threatening complications in patients presented following traumatic perforating corneal laceration with associated lens capsule disruption. Procedures Seventy‐seven patients (10 cats and 67 dogs) were evaluated with this injury; of these, 47 were presented acutely and treated surgically and/or medically. Successful outcome was defined as functional vision in the treated eye. Results The 47 patients with acute injuries were divided into 3 treatment groups A‐C for comparison; A ‐ corneal repair/lens removal (n = 15), B ‐ corneal repair/no lens removal (n = 9), C – medical management (n = 23). Groups A and B showed a significantly greater rate of vision loss compared to Group C that was most obvious greater than 18 months post‐injury (P = 0.029 and 0.0097, respectively). Cox proportional hazards regression analysis found a significantly higher increased rate of vision loss in Group A (HR = 4.5; P = 0.023) and a higher but nonsignificant increased rate of vision loss in Group B (HR = 3.0; P = 0.23) compared to Group C after controlling for age and cause of injury. The length of the corneal laceration and time interval from injury to referral were also relevant prognostic factors. Conclusions Medical management is an appropriate therapy for patients of all ages suffering perforating corneal injuries with associated lens capsule disruption. Patients with corneal injuries requiring surgical repair or managed by lens removal following corneal repair suffered vision‐threatening complications approximately 3 to 4.5 times the rate of patients treated by medical management, respectively. Favorable prognostic signs for treatment by medical management include good corneal wound apposition and a formed anterior chamber without uveal prolapse or continued aqueous leakage.     

Type IV dermoid sinus,intramedullary dermoid cyst and spina bifida in a Cane Corso

A 1-year-old male Cane Corso was presented for progressive hindlimb neurologic deficits, with a history of suspected recurrent meningitis. Physical examination and advanced diagnostic imaging findings were suggestive of a thoracic dermoid sinus extending into the dura mater, and spina bifida. After initial medical treatment, the lesion was surgically excised, and the presence of an intramedullary cyst in continuation with the dermoid sinus was confirmed, requiring partial durectomy and myelotomy for removal. Histopathological examination of the excised tissue confirmed the diagnosis of a dermoid sinus associated with an intramedullary dermoid cyst. After surgery, the dog temporarily declined neurologically but then showed progressive neurological improvement. This report describes presentation and successful surgical treatment of a type IVa dermoid sinus associated with an intramedullary dermoid cyst and spina bifida in a dog.     

Cholangiohepatitis and pancreatitis secondary to severe gastroduodenal ulceration in a foal

A 2-month-old foal was presented with clinical signs of colic. Gastroduodenal ulceration was suspected. A poor response to medical treatment and signs of gastroduodenal obstruction led to celiotomy and an attempted bypass procedure. The foal was euthanized and postmortem examination revealed gastric ulceration, segmental duodenal stenosis, and severe chronic cholangiohepatitis and pancreatitis.     

A retrospective study of presentation, treatment, and outcome of free-ranging raptors in Greece (1997-2000).

A retrospective study was conducted on free-ranging raptors (n = 402) presented to the Veterinary Medical Teaching Hospital, School of Veterinary Medicine, Aristotle University of Thessaloniki, Greece, during a 3-yr period (1997-2000). Representatives of 19 species were admitted from taxonomic orders Accipitriformes (n = 295), Falconiformes (n = 35), and Strigiformes (n = 72). Traumatic injuries (n = 305, 75.8%) were the most common cause of presentation in all raptors. Starvation (n = 38 birds, 9.4%) was the second most common reason, whereas toxicoses (n = 28, 6.9%) were suspected in a limited number of birds. Orphans (n = 31, 7.7%) were presented during breeding season primarily because of inappropriate human intervention. Surgical and medical treatment was given to all birds when necessary. In total, 229 (56.9%) of the presented raptors were successfully rehabilitated and released, 121 (30%) were rehabilitated but nonreleasable, whereas 52 (12.9%) of them died despite treatment. Human intervention (79.2%) plays the most important role in birds of prey morbidity and mortality.     

Discospondylitis in association with an intra-abdominal abscess in a dog

An 11-year-old German shepherd dog cross was presented with a six-week history of weight loss and abdominal distension. A diagnosis of abdominal abscess and discospondylitis was made. The dog responded to surgical excision of the abscess and conservative medical treatment for discospondylitis.     

Accidental colchicine poisoning in a dog

A 14-month-old toy poodle-cross was presented, after ingesting the owner's colchicine medication, with severe gastrointestinal disturbances and in shock. Despite aggressive medical management, the patient was euthanized approximately 24 hours after the ingestion. The clinical features, treatment, and necropsy findings of colchicine poisoning are discussed.     

Acute pancreatitis attributed to dietary indiscretion in a female mixed breed canine

A female, mixed-breed dog was presented with signs of abdominal discomfort and vomiting of 24 h duration following an episode of dietary indiscretion. Clinical signs, previous medical history, and diagnostic tests supported a diagnosis of acute pancreatitis. Specific and supportive treatment was instituted, and clinical signs resolved 10 d after presentation.     

Retinal detachment in horses: 40 cases (1998-2005)

OBJECTIVE: To determine clinical features, ophthalmic examination findings, etiology, treatment, and outcome of horses diagnosed with retinal detachment (RD). ANIMALS STUDIED: Forty horses, presented to the North Carolina State University and The Ohio State University Veterinary Teaching Hospitals from 1998 to 2005 that were diagnosed with RD. PROCEDURE(S): Horses with documented RD, confirmed either on ophthalmic examination or by ultrasonography, and with a complete medical record were included. Information retrieved from the medical records included signalment, presenting complaint, duration of clinical signs, ophthalmologic examination findings, diagnostics performed, identified cause of the retinal detachment, treatment given, and outcome. RESULTS: Forty horses (46 eyes) were diagnosed with RD. Mean +/- SD duration of clinical signs of ocular disease was 10.5 +/- 14.7 months. Thirty-four horses presented with unilateral involvement, 6 with bilateral, 14 with partial and 32 with complete RD. Ultrasonography was used to make the diagnosis in 26 eyes, while RD was diagnosed on routine ocular examination in 20 eyes. Bullous RD was the only type of RD observed, although small vitreal traction bands were considered secondary to the underlying inflammation or trauma. RD caused by equine recurrent uveitis (ERU) was diagnosed in 27 of 40 (67.5%) horses. Trauma-induced RD involved 10 of the 40 horses (25%). Presenting problems included known ERU (n = 16), acute or progressive vision loss (n = 9), known ocular trauma (n = 6), cataract (n = 6), and a cloudy cornea (n = 3). No horses regained vision after RD despite therapy. Many eyes were enucleated or eviscerated, or the horses were euthanized. Seven eyes with complete RD were noted to be unchanged and comfortable with medical therapy. CONCLUSIONS: The visual prognosis of RD in horses is grave; however, horses with nontraumatic RD (most commonly ERU) may be able to maintain a comfortable but blind globe with anti-inflammatory medical therapy.     

Septic peritonitis and uroperitoneum secondary to subclinical omphalitis and concurrent necrotizing cystitis in a colt

A 15-day-old American Quarter horse colt was presented for depression and pyrexia. Peritonitis was diagnosed following peritoneal fluid analysis. Exploratory laparotomy revealed an area of focal necrosis over the dorsal wall of the urinary bladder leading to peritonitis and uroperitoneum. The affected area of the urinary bladder was resected and the peritonitis resolved with medical treatment.     

Acupuncture as a treatment modality for back problems.

Concepts of acupuncture in traditional Chinese medicine are presented for clarity and contrast to Western medical concepts. Various acupuncture techniques and methods are discussed including dry needling, electroacupuncture, acupuncture using hypodermic needles, and injecting various solutions into the acupuncture sites. Potential complications and precautions are also presented. A type of chronic back pain is discussed that is possibly associated with a radiculopathically induced, hypersensitivity myofascial syndrome that presents as a fibromyalgia-like syndrome. Effective acupuncture treatment for the described chronic fibromyalgia-like syndrome is discussed.     

Laparoscopic esophagopexy,fundopexy, and hiatal herniorrhaphy for refractory regurgitation in a racing Alaskan husky sled dog

A 2-year-old intact female Alaskan husky sled dog was presented with a history of chronic exercise-induced regurgitation refractory to medical management. Previous diagnostics were unremarkable except for an endoscopic examination and histopathologic evaluation of the upper gastrointestinal tract that revealed the presence of Helicobacter spp. and mild non-specific inflammation of the proximal duodenum. A laparoscopic hiatal herniorrhaphy, esophagopexy, fundopexy, and ovariectomy were performed without complications in anesthesia or surgery and clinical improvement was observed with continued follow-up for 8 months after surgery.Key clinical message:Surgical treatment for hiatal hernia may be considered in racing Alaskan sled dogs with regurgitation refractory to gastric protectant therapy.     

PARACLOACAL GLAND CARCINOMA IN A SUGAR GLIDER (PETAURUS BREVICEPS)

A male sugar glider (Petaurus breviceps) was presented to the National Taiwan University Veterinary hospital for repeated self-mutilation of the cloacal region. After correction of husbandry deficiencies and medical management of the lesion, the condition improved but a pericloacal mass was found. Surgical removal of the mass resolved the self-mutilation, and a dorsal paracloacal gland carcinoma was diagnosed on histopathological examination. Straining to defecate and a pericloacal mass could indicate neoplasia in sugar gliders. A tumor should be differentiated from chronic inflammation, infection, paracloacal gland impaction, and hyperplasia. Surgical removal is recommended as a treatment for paracloacal gland carcinoma in sugar gliders. Further monitoring is suggested after surgical removal of the tumor.     

Successful resolution of a preputial prolapse in an alpaca using medical therapy

A 2-year-old intact male alpaca was presented for a post-breeding preputial prolapse of 5 days duration. The internal lamina of the prepuce was prolapsed approximately 6 cm and the exposed preputial epithelium was edematous and necrotic. Following 7 days of medical treatment, resolution of the preputial prolapse was achieved.     

Focal myasthenia gravis in a dog.

A 10-month-old American cocker spaniel was evaluated for megaesophagus, aspiration pneumonia, but no appendicular muscle weakness. During hospitalization, weakness of the facial muscles developed, this resolved with anticholinesterase administration. Serum antibodies against acetylcholine receptors were documented, confirming the diagnosis of focal myasthenia gravis. Diagnosis, management, and medical treatment are discussed.     

Prevalence of gastrointestinal tract lesions in 73 brachycephalic dogs with upper respiratory syndrome

OBJECTIVES: To determine the prevalence of gastrointestinal tract lesions in brachycephalic dogs with upper respiratory tract disease. METHODS: The gastrointestinal tract and respiratory disorders of 73 brachycephalic dogs presented with upper respiratory signs were evaluated. Clinical signs and endoscopic and histological anomalies of the upper digestive tract were analysed. RESULTS: A very high prevalence of gastrointestinal tract problems in brachycephalic dogs presented with upper respiratory problems was observed clinically, endoscopically and histologically. Endoscopic anomalies of the upper digestive tract were present even in dogs without digestive clinical signs. Furthermore, histological evaluation of the digestive tract sometimes showed inflammatory lesions not macroscopically visible at endoscopy. Statistical analysis showed a relationship between the severity of the respiratory and digestive signs. This was significant in French bulldogs, males and heavy brachycephalic dogs. CLINICAL SIGNIFICANCE: These observations show a correlation between upper respiratory and gastrointestinal tract problems in brachycephalic breeds with upper respiratory disease. Surgical treatment of respiratory disease could improve the digestive clinical signs, and/or gastro-oesophageal medical treatment could improve the outcome for surgically treated brachycephalic dogs.     

A case of gastrinoma in a Shih-Tzu dog

A five-year-old male Shih-Tzu dog presented with severe vomiting and weight loss. The clinical signs were successfully improved by an eight-day treatment with an H(2)-receptor antagonist, gastrointestinal protectant and antibiotics. Ten days later, however, recurrence of vomiting was seen despite continuous medical treatment. Based on clinical signs and the results of various diagnostic tests including CBC, biochemical analysis, contrast radiography, and endoscopy, a duodenal or pancreatic neoplasm was suspected and exploratory laparotomy was conducted. Some swollen pancreatic regions were found, and biopsy of the pancreas indicated the diagnosis of a gastrin-secreting tumor. Consequently, based on a high serum gastrin level as well as clinical signs and immunohistological findings, we diagnosed the disease as canine gastrinoma, a rare tumor of the pancreas.
