Abstract

This study investigates the occurrence of erythematous lip lesions in a captive sun bear population in Cambodia, including the progression of cheilitis to squamous cell carcinoma, and the presence of Ursid gammaherpesvirus 1. Visual assessment conducted in 2015 and 2016 recorded the prevalence and severity of lesions. Opportunistic sampling for disease testing was conducted on a subset of 39 sun bears, with histopathological examination of lip and tongue biopsies and PCR testing of oral swabs and tissue biopsies collected during health examinations. Lip lesions were similarly prevalent in 2015 (66.0%) and 2016 (68.3%). Degradation of lip lesion severity was seen between 2015 and 2016, and the odds of having lip lesions, having more severe lip lesions, and having lip lesion degradation over time, all increased with age. Cheilitis was found in all lip lesion biopsies, with histological confirmation of squamous cell carcinoma in 64.5% of cases. Single biopsies frequently showed progression from dysplasia to neoplasia. Eighteen of 31 sun bears (58.1%) had at least one sample positive for Ursid gammaherpesvirus 1. The virus was detected in sun bears with and without lip lesions, however due to case selection being strongly biased towards those showing lip lesions it was not possible to test for association between Ursid gammaherpesvirus 1 and lip squamous cell carcinoma. Given gammaherpesviruses can play a role in cancer development under certain conditions in other species, we believe further investigation into Ursid gammaherpesvirus 1 as one of a number of possible co-factors in the progression of lip lesions to squamous cell carcinoma is warranted. This study highlights the progressively neoplastic nature of this lip lesion syndrome in sun bears which has consequences for captive and re-release management. Similarly, the detection of Ursid gammaherpesvirus 1 should be considered in pre-release risk analyses, at least until data is available on the prevalence of the vi

45. Calcinosis circumscripta in a rabbit with recurrent cervical myelopathy.

Abstract

The clinical, imaging and histopathologic findings in this case are similar to those reported in humans with calcification of the ligamentum flavum, and in dogs with calcinosis circumscripta. A 4-year-6-month old, male neutered domestic rabbit presented with a 3-week history of progressive pelvic limb ataxia. The underlying cause in this case remains unknown but calcinosis circumscripta should be included in the differential diagnosis of cervical myelopathy in rabbits. [Extracted from the article]

Abstract

Einleitung: Eine Strategie zur Veringerung von pemanenten Paresen des N. laryngeus recurrens (RLNP) in der Schildrüsenchirurgie ist die obligate Nervenpräparation. Der Effekt des intraoperativen Neuromonitorings (IONM) des N. laryngeus reccurrens (RLN) ist noch immer unklar.Methoden: Es wurden 913 Patienten mit Hemithyroidectomie oder totaler Thyroidektomie mit 1602 gefährdeten Nerven (NAR) mittels Laryngoskopie und Videostroboskopie prea- und postoperativ prospektiv untersucht. In jedem Fall wurde eine langstreckige Präparation des RLN vorgenommen. Dabei wurde kein IONM eingesetzt. Benigne (BT) (1014 NAR) und maligne Schilddrüsenerkrankungen (MT) (578 NAR) wurden getrennt analysiert. Eine RLNP wurde nicht vor 2 Jahren ihres Bestehens als permanent bezeichnet.Ergebnisse: Es wurden 2,6% und 4,5% temporäre RLNPs je Nerv in der BT bzw. MT Gruppe identifiziert, und nur 0,3% und 0,9% an permanenten RLNPs in den jeweiligen Gruppen.Schlussfolgerungen: In den meisten Studien mit Nervenpräparation war die Rate an RLNPs (temporär und permanent) niedriger als in solchen ohne Durchführung einer Nervenpräparation. Hingegen zeigten Studien mit IONM keine Verbesserung der Rate. Eine obligate Nervenpräparation verringert also die Anzahl permanenter RLNP wirksam. Neben der indirekten Laryngoskopie sollte bei allen Patienten mit nicht eindeutig normaler beidseitiger Larynxfunktion und Stimmqualität unbedingt eine Videostroboskopie durchgeführt werden, um Fehldiagnosen zu vermeiden.
