Abstract
A 16-year-old male Guinea baboon (Papio papio) was evaluated for weakness and focal wet fur of 1-week duration. A pyothorax caused by Streptococcus anginosus was diagnosed. A surgical approach was chosen, combined with a systemic antibiotic therapy. Medical imaging and C-reactive protein follow-up revealed the resolution of the pyothorax.

Abstract
Aspergillosis is a major health problem in captive penguins due to the inhalation and the development of airborne spores of opportunistic environmental molds of the genus Aspergillus. Diagnosis is often delayed and treatments, based on the use of azole antifungals, are not fully effective. This study assesses the risk of exposure to Aspergillus sp. and determines the environmental reservoirs in the direct environment of a colony of Humboldt penguins (Spheniscus humboldti) in a zoological park in Paris, and the risk of contamination with resistant isolates. Every 15 days between February and May 2022, environmental samples (air and subtract from the nests, pond water, pigeon and penguin droppings) were carried out in the penguin enclosure as well as clinical samples (one-time non-invasive sampling on chicks), and screened for Aspergillus sp. conidia. From 191 environmental samples, 264 strains of Aspergillus including 221 strains of A. fumigatus were isolated, mostly from ambient air, in the nests, and pond water. No "at risk" areas in the penguin environment have been highlighted, nor an increased risk because of the proximity with urban wild birds. However, the load of airborne Aspergillus in the nests increased significantly with outdoor temperature. Of the 221 strains isolated, we identified only one azole-resistant strain, displaying the TR34/L98H mutation in the cyp51A gene. This low prevalence of resistant strains may probably be partly explained by the urban location of the zoological park, surrounded by kilometers of urban areas without agricultural activities.

Abstract
Very little information is available in veterinary literature concerning chemical contraception in elasmobranchs. To decrease breeding and adverse reproductive behaviors, male Potamotrygon sp., housed in two zoologic institutions, were treated using methods used in other elasmobranchs. Four animals received deslorelin acetate implants (Suprelorin 4.7 mg and 9.4 mg), four animals received a gonadotropin-releasing hormone vaccine (Improvac 50-100 µg) twice separated by 1 mon, and two animals were not treated to serve as controls. Health checks, including blood sampling, coelomic ultrasound, and sperm analysis, were performed bimonthly and then monthly over almost 2 yr. Microscopic examination of sperm never revealed any significant change in concentration or motility. Size of testes and seminal vesicles glands did not change significantly after treatment. Plasma testosterone concentrations were stable (∼1 ng/ml) in intact and vaccinated animals throughout the study period. Plasma testosterone level increased significantly after deslorelin implantation and remained very high for at least 13 mon, never returning to initial values. Peak concentration varied according to the deslorelin acetate concentration used. Aggression toward females continued despite the use of contraception. Histopathologic examination on dead stingrays revealed active testicular tissue. These results suggest that deslorelin acetate implants and GnRH vaccine are ineffective at dosages used in our cases. Implants caused a continuous stimulation of the hypothalamic-pituitary-gonadal axis that could be harmful for the animals.

Abstract
CASE DESCRIPTION A 7-month-old hand-reared female Bennett's wallaby (Macropus rufogriseus) was evaluated for bilateral ocular opacity of 3 months' duration. CLINICAL FINDINGS On physical examination, the wallaby was in good overall condition. An ophthalmic examination revealed mature cataracts in both eyes (OU). The cataracts were suspected to have a nutritional origin as it has been described in hand-reared macropods. Results of tonometry were normal OU. Results of CBC and serum biochemistry were unremarkable. The wallaby was premedicated with medetomidine and ketamine hydrochloride. Ocular ultrasonography performed while the wallaby was anesthetized revealed a thickened and opaque lens, mildly heterogeneous vitreous humor, and no sign of retinal detachment OU. An electroretinogram confirmed functional retinae OU. TREATMENT AND OUTCOME Surgery was considered necessary for welfare reasons. Phacoemulsification and vitrectomy were performed without intraoperative complication. The wallaby recovered uneventfully, and systemic NSAID, topical corticosteroid, and systemic and topical antimicrobial therapy were prescribed. One year later, the animal had vision OU. Physical examination did not show any vision-threatening postoperative complications. CLINICAL RELEVANCE The etiology of nutritional cataracts is not fully understood in macropods, but this condition is rather common in these species. To our knowledge, this is the first detailed report of a successful bilateral phacoemulsification and vitrectomy in a Bennett's wallaby.

Abstract
A 14-year-old unsexed African grey parrot (Psittacus erithacus erithacus) was presented with a 12-hour history of neurological signs and vomiting. The external physical examination of the patient revealed lethargy, moderate hypothermia, a head tilt, and horizontal nystagmus. Whole-body radiographic imaging and blood biochemistry parameters were unremarkable, and a serological test to detect bornavirus was negative. A computed tomography scan of the bird revealed a large cystic lesion located on the fourth ventricle of the brain. In spite of treatment (nonsteroidal anti-inflammatory drugs and antibiotic and antiparasitic therapy), the parrot's health continued to decline, and it was euthanatized 12 days after presentation. A complete postmortem examination was performed on the patient's brain. Histopathological interpretation of tissues submitted described a large neoformation composed of cells arranged in perivascular pseudorosettes. Hyperchromatic nuclei and marked anisokaryosis were suggestive of a malignant tumor. The tissue mass was associated with significant dilation of the fourth ventricle and a severe peripheral gliosis. The histopathological diagnosis of the neoformation was an ependymoma. Ependymomas are glial tumors of the ependymal cells that line the central canal and the ventricles of the brain and are rarely described in mammals. In birds, ependymomas were only described in budgerigars (Melopsittacus undulatus). In human medicine, the recommended treatment is surgical removal of the tumor when possible, followed by radiotherapy.

Abstract
PURPOSE In the evolution of the minimally invasive treatment of vertebral compression fractures, vertebral body stenting (VBS) was developed to reduce intraoperative and secondary loss of vertebral height. Particularly in combination with the usage of biodegradable cement, the influence of VBS on the rate of intraoperative complications and long-term outcome is unclear. The purpose of this study was to investigate the differences between balloon kyphoplasty (BKP) and VBS regarding their long-term clinical and radiological outcome in combination with calcium phosphate (CaP) application instead of polymethyl methacrylate (PMMA). METHODS This retrospective study included 49 patients with fresh mono-segmental thoracolumbar fractures without neurological signs treated with VBS or BKP and CaP cement (Calcibone). The outcome was evaluated with the visual analogue pain scale (VAS), the Oswestry disability score (ODI), and radiologically assessed. RESULTS In the course of the radiological follow-up, the VBS group showed statistically significant less vertebral height loss than the BKP group. However, with respect to VAS and ODI scores there were no statistically significant differences between the VBS and BKP group in the clinical follow-up. The rate of cement leakage was comparable in both groups. CONCLUSIONS Both techniques facilitated good clinical results in combination with absorbable cement augmentation. In particular, the VBS enabled us to benefit from the advantages of the resorbable isothermic CaP cement with an improved radiological outcome in the long term compared to BKP. However, there was a mentionable loss of reduction in the follow-up in both groups compared to previously published data with PMMA cement. These slides can be retrieved under Electronic Supplementary Material.

Abstract
One hundred fifteen patients with nonunions or delayed fracture healing were treated with high-energy shock waves. After shock wave treatment, immobilization of the fracture also was done. The followup was at least 3 months and as long as 4 years. In 87 patients (75.7%), one treatment with shock waves resulted in bony consolidation with a simultaneous decrease in symptoms. Besides negligible local reactions (swelling, hematomas, petechial hemorrhages), no complications were observed. The treatment was noninvasive, and personnel and technical requirements were not problematic. The authors concluded that the application of extracorporeal shock wave therapy should be the first choice of treatment for patients with nonunions and delayed bone fracture healing.
