Use of a Cardiac Access Port for Repeated Collection of Blood Use of a Cardiac Access Port for Repeated Collec- tion of Blood Samples from Desert Tortoises (Gopherus agassizii) J. WIMSATT, DVM, PHD, J. D. JOHNSON, DVM, AND B. A. MANGONE, DVM Abstract _ Repeated collection of blood samples may be required during pharmacokinetic studies and can be challenging in tortoises because of size and location of the major vessels. The technique described here is relatively safe, inexpensive, and potentially reversible. A sterile rubber stopper is surgically inserted into a hole drilled in the plastron over the heart to allow collection of multiple blood samples over a period of several days or weeks, using a 27-gauge needle. During surgical placement of the port, pericardial excision was performed on some tortoises, but not others, to assess the risk of cardiac tampanade when collecting samples. In 13 of 14 tortoises, the technique appeared to be well tolerated. Pericardiectomy did not appear to be neces- sary. Ports were left in 6 tortoises for 6 months without evidence of adverse effects. Ports were removed from 5 other tortoises, and the defect in the plastron was repaired; these tortoises appeared healthy 8 months later. Four months after removal of the port, 2 other tortoises were euthanatized as a result of advanced respiratory tract disease. Postmortem examination revealed that the plastron defects were completely filled with bone; however, they also had evidence of mild fibrotic myocardial changes that were attributed to repeated cardiocentesis.

Abstract: The gross and microscopic lesions of tissues making up the head of amphibians and reptiles are reviewed and described. Tissues from the integument, musculoskeletal system, nasal cavity and oropharynx, special senses (eye and ear) and central nervous system are included. Etiologic categories include infectious, noninfectious and neoplastic disease. Introduction Diseases of the head can affect a number of organ systems including skin, upper gastrointestinal and respiratory systems, musculoskeletal system, special senses, and central nervous system. A variety of infectious, noninfec- tious, and neoplastic causes are possible. This presentation will cover the gross and histologic features of common conditions seen in a diagnostic pathology practice. General disease categories are infectious, noninfectious, and neoplasia. Infectious disease may be due to viruses, bacteria, fungi, and parasites. Noninfectious conditions include trauma and toxins. Reported neoplasms include epithelial, mesenchymal, and melanomas/chromatophoromas. Skin Infectious disease Viral disease: A number of viral infections have been reported to involve the skin of amphibians and reptiles. These include herpesvirus in both, poxvirus in both, papillomavirus possibly in both and iridovirus/ranavirus in both amphibians and reptiles. Herpesvirus: Cutaneous herpes infection has been reported in Italian frogs.1 Grossly small variably-sized, white to gray vesicles are seen. Histologically there is epidermal hyperplasia, epithelial cell karyomegaly and intra- nuclear inclusion body formation. In reptiles, grey patch disease (Chelonid herpesvirus 1) affects cultured green turtle hatchlings.
