The fungal disease mucormycosis has affected Tasmanian platypuses for nearly three decades. We investigated the influences of mucormycosis on the hematologic, plasma biochemical, and other indicators of health in free-living platypuses across 18 Tasmanian river catchments. Live trapping enabled sampling of 161 (apparently) healthy and six ulcerated, mucormycosis-affected platypuses in 75 rivers and streams between January 2008 and June 2009. There were no obvious differences in any hematologic or biochemical measures between healthy and mucormycosis-affected platypuses. However, multivariate analysis revealed that ulceration was associated with living at higher altitudes, low tail fat content (high tail fat index), and low trypanosome load. There was evidence of overall lymphocytosis and monocytosis in animals from areas currently affected by mucormycosis, which suggests that some level of immune response to the introduced fungus is now widespread in disease-affected catchments. Animals from currently, historically, and possibly disease-affected catchments had lower neutrophil counts, mean cell volumes, plasma alkaline phosphatase, alanine aminotransferase, and aspartate aminotransferase levels, and higher plasma gamma-glutamyl transpeptidase and platelet counts compared to animals from catchments with no evidence of infection. Reference intervals were generated for all hematologic and biochemical measurements. Since this is the most comprehensive, systematic, and large-scale assessment of the health of the Tasmanian platypus to date, these references intervals should act as the standard against which future studies of platypuses in Tasmania should be compared.

We present the case of a 68-year old gentleman with previously diagnosed myelodysplastic syndrome with pancytopenia who presented with exophthalmia, rhinorrhea, and ophthalmoplegia. Nasal endoscopy revealed black necrotic lesions. He was diagnosed with rhino-orbital mucormycosis and commenced on intravenous antifungals. Despite this therapy he progressed to have total unilateral loss of visual acuity and cutaneous necrosis. He underwent emergency orbital exenteration and extensive cheek and sinus debridement. Necrotic lesions were found in the orbit, the maxillary and ethmoidal sinuses. He underwent reconstruction of this defect using a free myocutaneous ALT flap with a segment of vastus lateralis. Prior to surgery his anemia and thrombocytopenia were addressed with packed red cell and platelet transfusions as well as preoperative thromboelastography (TEG) to measure functional fibrinogen to platelet ratio. Intraoperative platelet administration was guided by repeated TEG analysis. There were no significant intraoperative or postoperative bleeding complications and both flap and donor site healed unremarkably. Few reports exist in the literature related to free tissue transfer in patients with hematological disorders but low platelet count has been implicated in an increased complication rate.
