Percutaneous Cementoplasty in the Palliative, Multimodal Treatment of Primary Bone Tumors of the Distal Aspect of the Radius in Four Dogs

Objective— To (1) evaluate the analgesic effect of percutaneous cementoplasty (PC) in dogs with primary bone tumor (PBT) of the distal aspect of the radius and (2) evaluate the impact on the course of disease by adding PC to a palliative, multimodal treatment protocol in these dogs.
Study Design— Prospective pilot study.
Animals— Dogs (n=4) with PBT of the distal aspect of the radius.
Methods— Tumor lesions were filled percutaneously with polymethylmethacrylate under fluoroscopic guidance. Pamidronate was administered once in a week before PC. Radiotherapy and chemotherapy were initiated 2 and 6 weeks after PC, respectively. Force plate analysis was performed immediately before 2, and 6 weeks after PC. Survival time was defined from PC to euthanasia.
Results— Two dogs had a significant increase in peak vertical force 2 weeks after PC ( P =.043) and remained free of lameness for 18 and 20 weeks, respectively. One dog had an acute relapse after an initially lame-free period of 10 days. The remaining dog failed to improve ( P =.686). Three dogs developed at least 2 complications including transient worsening of the lameness after PC, cement leakage, wound infection and suspected thromboembolism in combination with cough and anemia. Median survival was 4.8 months (range, 1–5.7 months).
Conclusions— PC in combination with pamidronate significantly improved lameness in 2 dogs; however, PC is not risk-free. Deep wound infection, intraarticular cement leakage, and venous thrombosis were the main complications.
Clinical Relevance— PC might be a useful addition to established palliative, multimodal treatment protocols in dogs with PBT; however, because of the complications encountered PC warrants further study before routine use can be considered.     

Resection of a Large Intra‐Abdominal Tumor in the Mexican Axolotl: A Case Report

Objective— This case report describes the surgical removal of an intra‐abdominal tumor from a Mexican axolotl (Ambystoma mexicanum). The animal was admitted with left abdominal swelling that had increased over 4 months. Methods— Surgical removal was performed under general anesthesia with MS222 under an operating microscope. Exploratory laparotomy was performed through 2.5 dorsocranial skin incision in the left flank, followed by subcutaneous dissection. Results— The tumor involved the spleen, was adjacent to the descending colon, and supplied by vessels from the spleen, stomach, and colon. The mass was removed by clamping and transecting the spleen and the peritoneum was closed with a continuous suture pattern, while abdominal muscles and skin were closed in layers. After a total duration time of anesthesia of 90 minutes the animal was kept in prophylactic antibiotic baths. Tissue sections revealed characteristics of both lymphangiosarcoma and lymphosarcoma with an appearance typical for a malignant tumor. Conclusions— Abdominal surgery was performed in an axolotl and the surgical wound healed without complication.     

Integumental Structure in a Friesian Calf with Congenital Hypo-or Atriehosis Combined with Prognathia Inferior

Abstract— The integumental structure in a Friesian calf with congenital hypo-or atrichosis and prognathia is described. The most important feature was the presence of primary hair follicles with full glandular complements but without the hair forming parts (hair bulb with matrix).
Résumé— La structure du tégument d'un veau Frison atteinte d'une hypoou atrichose et d'un prognatisme est décrite. La principale caractéristique est l'existance de follicules pileux primaires possédant l'ensemble des glandes annexes, mais dépourvus de partie productrice de poil (bulbe avec matrice).
Zusammenfassung— Die Arbeit beschreibt die Hautstruktur eines Schwarzbunte-Kalbes mit Hypo-oder Atrichosis, die mit Prognathia inferior gekoppelt ist. Als wichtigste Beobachtung fällt auf, daß die vorhandenen Primärhaarfollikel die voile Ausstattung mit beiden Drüsentypen zeigen, der gesamte proximale Follikelanteil, der das eigentliche Haar bildet (Haarbulbus mit Haarmatrix), jedoch fehlt.
Resumen  Se describe la estructura integumentaria de un ternero frisón que padecía hipo/atricosis acom-pañada de prognosis mandibular. La característica relevante fué la presencia folículosos primarios junto con anexos glandulares completos, pero careciendo de las partes formadoras del pelo (bulbo piloso y matríz).     

Canine Thyroid Function in Adiposity and Certain Skin Ailments Studied by the EU Test

Abstract— Erythrocyte uptake in vitro of ¹³¹I-labelled triiodothyronine (EU test) was studied in dogs. A simultaneous estimation of blood cholesterol was made. The results indicate that hypothyreotic dogs can be detected by determination of EU and possibly of cholesterol. Dogs exhibiting alopecia and/or adiposity were shown to have significant lower EU and higher cholesterol values than clinical healthy dogs and those affected by acanthosis nigricans or dermatosis caused by infections or parasites. Résumé— L'auteur a étudié, chez le chien, l'absorption in vitro par les erythrocytes de la tri-iodothyronine I¹³¹ (test AE), cet examen étant accompagné du calcul estimatif du cholestérol sanguin. Les résultats obtenus portent à conclure que la détermination de 1'AE et, éventuellement, du cholestérol permet de déceler l'hypothyroïdie chez le chien. II a été constaté que chez les chiens atteints d'alopécie et/ou d'adiposité, les valeurs AE sont sensiblement plus faibles et les valeurs de cholestérol plus élevées que chez les sujets cliniquement normaux et chez ceux qui sont atteints soit d'acanthosis nigricans, soit de dermatoses dues aux infections ou aux parasites. Zusammenfassung— Erytrocytupptag in vitro av ¹³¹I-märkt trijodtyronin (EU-test) under-söktes samtidigt med blodkolesterolbestämning på hundar. Resultaten tyder på att hypothyros hos hund kan upptäckas genom denna bestämning av EU, eventuellt kombinerad medkolesterolbestämning. Hundar med alopcia och/eller adipositas visade sig ha signifikant lägre EU och högre kolesterolhalt än kliniskt friska djur och sadana som hade acanthosis nigricans eller dermatoser av infektiöst eller parasitärt ursprung.
