[more ▼] Abstract The objective of this retrospective study was to report the efficacy of a single daily oral dose of phenylpropanolamine (PPA) in the treatment of urethral sphincter mechanism incompetence (USMI) in bitches. Nine bitches diagnosed with USMI were treated with a single daily dose (1.5 mg/kg) of PPA for at least 1 month. Urethral pressure profiles (UPP) were performed in 7 dogs before treatment and repeated in 4 of them after treatment. Treatment with PPA resulted in long-term continence in 8/9 bitches. One dog did not respond to PPA and was treated surgically later. Recheck UPPs showed a significant increase in maximal urethral closure pressure in the 4 bitches after treatment with PPA compared to before treatment. In conclusion, long-term continence can be achieved in bitches affected with USMI after administration of a single daily dose of PPA (1.5 mg/kg).

[more ▼] Objectives: To evaluate the clinical efficacy of the transobturator vaginal tape inside-out (TVT-O) in incontinent female dogs affected with urethral sphincter mechanism incompetence (USMI) and to determine its urodynamic and morphologic effects. Study Design: Case series. Animals: Incontinent spayed female dogs (n=7). Methods: TVT-O tape was inserted in 7 incontinent female dogs diagnosed with USMI. Urethral pressure profilometry (UPP) and vaginourethrograms were performed preoperatively, and 1 and 3 months postoperatively. Clinical efficacy of the technique was evaluated and complications reported. Follow-up information was evaluated by a telephone questionnaire. Results: All dogs were continent immediately after the procedure. Incontinence recurred 2 months after surgery in 1 dog and was treated by phenylpropanolamine administration. At mean follow-up time of 11.3 months, 6 of 7 dogs were continent. An iatrogenic urethral tear occurred intraoperatively in 1 dog. No postoperative complications were encountered. The postoperative UPPs showed significantly increased maximal urethral closure pressure and integrated pressure. Postoperative vaginourethrograms were unremarkable. The surgical procedure did not modify the location of the urinary bladder neck in dogs with a ‘‘pelvic urinary bladder’’ preoperatively. Conclusions: TVT-O was efficient in maintaining short term continence in 6 of 7 dogs affected with USMI. Urethral sphincter mechanism incompetence (USMI) is the most common cause of acquired urinary incontinence in female dogs.1 It mainly affects mostly middle-aged, large breed, spayed female dogs.2,3 Clinical signs such as urine leakage during sleep or periods of excitement may develop a few weeks to several years after spaying, most commonly after 2–3 years.2,4,5 The cause is multifactorial with numerous factors identified or suspected to contribute to incontinence, including urethral tone and length, position of the urinary bladder neck, breed, size, neutering, obesity, age, and tail docking.2,3,6–16 The initial treatment of USMI is usually medical. Alpha-adrenergic drugs (eg, phenylpropanolamine [PPA]) are commonly used17–19 and the reported success rate ranges from 85–97% continence.19–22 Short-acting estrogens (estriol) [less ▲] Detailed reference viewed: 33 (9 ULg) Transobturator Vaginal Tape Inside Out for Treatment of Urethral Sphincter Mechanism Incompetence in Female Dogs: Cadaveric Study and Preliminary Study in Continent Female DogsClaeys, Stéphanie ; ; De Leval, Jean et alin Veterinary Surgery : The Official Journal of the American College of Veterinary Surgeons (2010), 39(8), 957-968 ABSTRACT Objectives – 1) To describe a surgical technique adapted from the “transobturator vaginal tape inside-out” (TVT-O) used in women and to define the trajectory of the tape on cadavers, and 2) To ... [more ▼] ABSTRACT Objectives – 1) To describe a surgical technique adapted from the “transobturator vaginal tape inside-out” (TVT-O) used in women and to define the trajectory of the tape on cadavers, and 2) To determine the urodynamic and morphological effects of the TVT-O in continent bitches. Study Design – Cadaveric and experimental in vivo study. Animals – Fresh female canine cadavers (n = 12) and spayed female Beagle dogs (n = 2). Methods – 1) TVT-O was inserted in 12 cadavers. Dissection was performed and distances between the tape and neighboring structures were recorded. 2) TVT-O was inserted in 2 continent female Beagle dogs. Urethral pressure profilometry (UPP) and vaginourethrograms were performed preoperatively, immediately after surgery and 2, 4, and 6 months postoperatively. Histopathology was performed 6 months after surgery. Results – 1) TVT-O tape was consistently located in a perineal space before entering the obturator foramina and was located at a safe distance from major neurovascular structures including the femoral vessels and the obturator nerve. 2) UPP showed an increased integrated pressure postoperatively up to 4 postoperative months. Vaginourethrograms performed postoperatively showed a ventral displacement and narrowing of the distal urethra. Histopathological examination of the tissues surrounding the tape revealed a mild fibroblastic proliferation with a mild to minimal lympho-plasmocytic inflammatory infiltration. Conclusions - TVT-O is a feasible and accurate procedure which can be performed in continent bitches with a low risk of complications.

In this second part of a three-part review, the pathophysiology of impaired urethral contractility (including urethral hyper- and hypotonicity) in the bitch and in women is discussed. Urethral sphincter mechanism incompetence (USMI) is the most common form of acquired urinary incontinence in bitches and is characterized by a decreased urethral tone. The pathophysiology and current recommended medical treatment options for USMI and cases of modified urethral tonicity due to a neurological disorder or functional outlet obstruction are discussed. Treatment options in human medicine in cases of impaired urethral contractility are described.

[more ▼] OBJECTIVE: To describe outcome of treatment with propofol and phenobarbital for status epilepticus (SE) after portosystemic shunt (PSS) attenuation. CASE OR SERIES SUMMARY: Three dogs without preceding seizure activity, were diagnosed with a single extrahepatic PSS. Following standard preoperative medical therapy, an ameroid constrictor was placed surgically. Recovery was uneventful until spontaneous SE developed 46-96 hours after surgery. After unsuccessful seizure control with benzodiazepines, dogs were treated with a bolus of propofol followed by a propofol constant rate infusion. Phenobarbital was concurrently administered and supportive care was optimized. All dogs recovered uneventfully over the next 7-9 days. Over the following months phenobarbital was slowly tapered. All dogs have been free from antiepileptic drugs for several months, without recurrence of neurologic signs. NEW OR UNIQUE INFORMATION PROVIDED: In this case series, we describe the treatment of 3 dogs with propofol and phenobarbital for refractory SE following attenuation of a single congenital PSS. After weaning of the propofol constant rate infusion, and tapering and discontinuation of phenobarbital over the following months, all dogs experienced a complete recovery. This study provides evidence that use of propofol in combination with phenobarbital may be efficacious for management of SE in dogs after PSS surgery.

Epiglottic cysts, laryngeal granulomas and nasopharyngeal turbinates in English Bulldogs were other previously unreported findings. No significant correlation between the respiratory score and any of the BWBP variables was detected. Compared to healthy dogs, brachycephalic dogs had a significantly lower Te/Ti ratio (expiratory time over inspiratory time), peak inspiratory flow (PIF) per kg bodyweight (BW), significantly higher peak expiratory flow (PEF) per kgBW, PEF/PIF, and enhanced pause. These variations are compatible with upper airway obstructions primarily in the extrathoracic airways. Following surgery, a significant decrease in PEF/PIF was detected. The study showed that BWBP could be used to characterise the respiratory strategy in brachycephalic dogs before and after surgery.

[more ▼] Urethral sphincter mechanism incompetence (USMI) is the most common cause of urinary inence in dogs. Surgery may be recommended if the animal does not respond to medical treatment or becomes refractory. In this third part of a three-part review, surgical options for the treatment of USMI are described. Colposuspension is the most frequently described procedure and offers a fair prognosis, with about 50% of the dogs being continent after surgery and most of the reminder being improved or more responsive to medical treatment. Urethropexy offers a similar success rate, but with a higher rate of complications. Endoscopic injection of collagen is an attractive technique due to its minimally invasive nature and low risk of adverse effects. Initial results may however deteriorate with time. Other procedures have been reported, but involve a low number of cases and have resulted in variable success rates. In women, stress urinary incontinence is mainly treated by minimally invasive procedures involving vaginal placement of sub-urethral slings.

[more ▼] L’incompétence du sphincter urétral (ISU) est la cause la plus fréquente d’incontinence urinaire chez la chienne adulte. Elle affecte typiquement les chiennes stérilisées, d’âge moyen et de grande race. Son traitement est initialement médical. La phénylpropanolamine (PPA) est le traitement médical de choix et son taux de succès varie de 85 à 97 % de continence. Des études expérimentales antérieures ont démontré l’avantage urodynamique d’une administration de PPA une fois par jour par rapport à l’administration 3 fois par jour recommandée habituellement. Aucune étude clinique n’a cependant été réalisée jusqu’à présent pour confirmer l’efficacité de ce protocole de traitement chez la chienne incontinente. Un traitement chirurgical est recommandé en cas de non réponse ou de réponse partielle au traitement médical, si la chienne devient réfractaire au traitement ou développe des effets secondaires, ou si les propriétaires ne souhaitent pas administrer un médicament à long terme. De nombreuses techniques chirurgicales ont été décrites pour traiter l’ISU chez la chienne mais aucune à l’heure actuelle ne permet de garantir un taux de continence complète élevé et ce, à long terme et avec un faible taux de complications. Le traitement de l’incontinence urinaire d’effort chez la femme est principalement chirurgical et implique le placement d’une bandelette sous-urétrale par voie vaginale. Parmi les techniques décrites, la TVT-O offre un très bon taux de succès et présente très peu de complications postopératoires. Les objectifs de ce travail étaient donc d’évaluer l’efficacité clinique d’un dosage quotidien unique de PPA et d’adapter la technique TVT-O à la chienne en passant par une étude préliminaire sur cadavres et chiennes Beagles saines pour ensuite l’utiliser chez des chiennes incontinentes atteintes d’ISU, afin d’en évaluer les effets cliniques, urodynamiques et morphologiques. Dans la première étude, l’efficacité clinique de la PPA administrée une seule fois par jour à un dosage de 1.5 mg/kg a été démontrée. En effet, le suivi à long terme (23.9 mois en moyenne) montre que 8 chiennes sur 9 étaient continentes après traitement. Une chienne n’a pas répondu à la PPA et a été traitée chirurgicalement. Aucun effet secondaire n’a été observé chez les animaux traités. D’un point de vue urodynamique, l’administration de PPA augmente significativement les valeurs de pression urétrale maximale de fermeture (MUCP). L’administration de PPA 2 à 3 fois par jour, telle que recommandée habituellement, n’est donc pas utile puisqu’une administration quotidienne unique, plus pratique et moins coûteuse pour les propriétaires, suffit à maintenir la continence chez 89 % des chiennes traitées. La faisabilité de la technique TVT-O a ensuite été évaluée chez la chienne. La dissection de 12 cadavres de chiennes après mise en place de la bandelette montre que la TVT-O est faisable chez la chienne moyennant certaines adaptations. Une épisiotomie est notamment nécessaire chez la chienne contrairement à la femme. Les résultats montrent que la bandelette est située à une distance raisonnable des structures neuro-vasculaires importantes, y compris les vaisseaux fémoraux et le nerf obturateur, minimisant le risque de les léser. Elle est également localisée de manière constante en arrière du muscle élévateur de l’anus, en région périnéale, rendant ainsi le risque de lésion vésicale quasi inexistant. La technique apparaît donc peu risquée et reproductible chez la chienne. L’application de la TVT-O chez 2 chiennes Beagles continentes nous a ensuite permis d’observer l’absence de complications intra- et postopératoires. D’un point de vue urodynamique, la pression intégrée (aire sous la courbe d’UPP représentant la résistance urétrale) est augmentée jusqu’à 4 mois après l’intervention. Les vagino-urétrographies postopératoires montrent un déplacement ventral et un rétrécissement de l’urètre distal juste en avant du méat urinaire. D’un point de vue histologique, les tissus entourant la bandelette montrent une réaction fibroblastique modérée accompagnée d’une réaction inflammatoire lympho-plasmocytaire légère à modérée. La bandelette semble donc relativement inerte et bien tolérée chez le chien. La tolérance de la bandelette est d’une importance majeure puisqu’une réaction inflammatoire excessive peut induire une érosion vaginale ou urétrale pouvant entraîner une infection. La TVT-O a ensuite été réalisée sur 8 chiennes incontinentes atteintes d’ISU. Après un suivi de 2 semaines à 12 mois (moyenne, 7.3 mois), 7 des 8 chiennes sont continentes. Une chienne a récidivé 2 mois après la chirurgie et a été traitée à la PPA. D’un point de vue urodynamique, MUCP et la pression intégrée sont augmentées significativement après l’intervention. L’augmentation de pression se situe principalement au niveau de l’urètre moyen. Il apparaît donc que la localisation du pic de pression urétrale postopératoire ne correspond pas à la localisation anatomique de la bandelette. Les vagino-urétrographies, pour la plupart non remarquables, montrent que la bandelette ne modifie pas la position du col vésical puisque les vessies en position pelvienne en préopératoire le restent en postopératoire. Une complication intra-opératoire s’est produite chez une chienne chez qui une lésion urétrale caudale a été créée pendant l’intervention. Aucune complication postopératoire n’a été observée. Les résultats cliniques à court et moyen terme de l’utilisation de la TVT-O dans le traitement de l’ISU chez la chienne sont donc très favorables. L’hypothèse d’un rétablissement d’un support urétral déficient, entraînant une restauration de la fonction urétrale, reste à démontrer.

[more ▼] OBJECTIVES: To evaluate the effectiveness of rhinotomy and surgical debridement associated with topical administration of 2 per cent enilconazole and oral itraconazole in dogs with severe or recurrent sinonasal aspergillosis. METHODS: A standard rhinotomy was performed on seven dogs. In the initial study, the bone flap was left attached cranially and replaced at the end of the procedure. In the main study group, the bone flap was discarded. Nasal passages were debrided and irrigated with enilconazole solution for one hour. Oral itraconazole was administered to four dogs for one month postoperatively. Follow-up rhinoscopy was performed in all dogs. RESULTS: All three dogs in the initial study had recurrence of the disease and two dogs had a second surgery to remove the flap. The main study group included four dogs in which the flap was initially removed, and the two dogs from the initial study that required a second surgery. At follow-up rhinoscopy, five dogs were free of aspergillus but had bacterial or inflammatory rhinitis and one dog had a small aspergilloma but was subsequently asymptomatic. Telephone follow-up revealed that four dogs were asymptomatic, one dog had intermittent sneezing and serous nasal discharge, and one dog had intermittent epistaxis. CLINICAL SIGNIFICANCE: Rhinotomy with removal of the flap combined with one-hour infusion of 2 per cent enilconazole and oral itraconazole resulted in satisfactory outcome in dogs with severe or recurrent aspergillosis.
