The RI established in this study provide a useful baseline for the assessment of hematologic and biochemical data in Friesian horses residing in North America.

An 11-year-old neutered male Alaskan Malamute mixed-breed dog was presented with a complaint of polyuria/polydipsia (PU/PD), weight loss, tachypnea, regurgitation, and a previous history of nontreated osteosarcoma of the right distal radius, diagnosed 21 months prior. On physical examination, an abdominal mass was palpated. The abdominal mass was aspirated and cytologically diagnosed as a neuroendocrine tumor, suspected to be a pheochromocytoma. Laboratory examination revealed a mild anemia and thrombocytopenia, markedly elevated ATP and ALP activities, and moderate hypercalcemia. A low-dose dexamethasone suppression test and endogenous adrenocorticotropic hormone (ACTH) concentration were compatible with pituitary hyperadrenocorticism. On urinalysis, proteinuria was noted as well as a high urine metanephrine/creatinine ratio, consistent with a diagnosis of pheochromocytoma. The dog was treated with supportive care and euthanized 6 months later due to decreasing quality of life. On necropsy, an extra-adrenal pheochromocytoma (paraganglioma) was diagnosed in the caudal abdomen, and a pituitary adenoma and an osteosarcoma of the right distal radius were confirmed.

This report details a case of reversible cold agglutinins in a dog with Mycoplasma cynos pneumonia. An 11-month-old female spayed Rhodesian Ridgeback was presented for lethargy and cough. Thoracic radiographs revealed an alveolar pattern present bilaterally in the cranioventral lung lobes. Septic neutrophilic inflammation with suspected Mycoplasma sp. organisms was noted on cytologic examination of a trans-tracheal wash, and the dog was treated empirically with IV ampicillin/sulbactam and enrofloxacin pending culture results. Red blood cell agglutination was noted unexpectedly on several blood film reviews during hospitalization; however, the dog never developed clinical or laboratory evidence of hemolysis. Cold agglutinins were demonstrated based on the results of a saline dilution and cold agglutinin test that showed agglutination at 4°C but not at room temperature (21°C) or 37°C. Based on a positive culture for M cynos, the dog was treated for 8 weeks with oral enrofloxacin. After clinical and radiographic resolution of the pneumonia, repeated saline dilution and cold agglutinin tests of peripheral blood were negative at all temperatures. Reversible, asymptomatic cold agglutinins are common in human patients with mycoplasma pneumonia, but this is the first reported case in a dog.

The endangered corals Orbicella annularis and O. faveolata are crucial to Caribbean reefs because of their large size and contribution to reef framework. The objective of this study was to describe the prevalence and progression of macroscopically evident lesions affecting Orbicella spp. in shallow fringing reefs in St. Kitts. Cross-sectional surveys in the spring of 2017 demonstrated 8 predominant lesion patterns affecting 59% of corals (95% CI: 55.8-62.1%), including annular yellow-brown pigmentation, focal brown pigmentation, focal bleaching, diffuse bleaching, annular black surface deposit, focal tissue loss with skeletal erosion, focal grey pigmentation, and growth anomaly. Longitudinal surveys of 47 tagged corals were performed from August 2016-May 2017 to track lesion progression. The 2 most common lesions, annular yellow-brown pigmentation (n = 30), and focal brown pigmentation (n = 21), showed mean (±SD) partial colony mortality growth of 0.26 ± 0.5 and 0.21 ± 0.45 cm2 d-1, respectively. Annular pigmentation progression severity was associated with a marginating band of bleaching (ordinal odds ratio [OOR] = 11.0), and yellow rather than brown color (OOR = 3.8). Bleaching lesions (n = 13), occurring during a time of elevated sea surface temperature, were most severe during October-December 2016, and persisted through April 2017, months after heat stress had subsided. Annular black surface deposits (n = 3) were associated with rapid progression of acute tissue loss, whereas focal tissue loss with skeletal erosion (n = 2) regressed within months, and focal grey pigmentation (n = 2) was quiescent for the length of the study. This study enforces concern for the extent to which Orbicella spp. are declining due to disease.

This study provides useful RIs for assessment of hematology and serum biochemical variables in a geriatric population of African Green monkeys in the Caribbean.
