Parasitological Analysis and Gill Histopathology of Pearl Dace (Semotilus Margarita) and Brook Stickleback (Culaea Inconstans) Collected from the Athabasca Oil Sands Area (Canada)

Pearl dace (Semotilus margarita) and brook stickleback (Culaea inconstans) were collected from tributaries of the Athabasca River (Alberta, Canada), upstream (reference site) and downstream of oil sands deposits where fish were expected to be exposed to naturally occurring oil sands constituents. The objective was to determine if fish collected from these sites exhibited differences in the prevalence or intensity of infection by parasites or in gill histology. Dace did not display significant differences in these parameters. Alternately, upstream stickleback were predominantly infected by complex life history parasites, while downstream fish were primarily infected by parasites with simpler life histories. Moreover, downstream stickleback exhibited significantly more clubbing and aneurysms in secondary gill lamellae relative to upstream fish. This suggested a difference in habitat quality between upstream and downstream sites. However, based on basic body condition parameters of the fish, it would appear that any impacts upon the health of the fish due to the presence of naturally occurring oil sands associated chemical constituents would have been minor.

Neuro-Behçet's disease presenting with tumour-like lesions and responding to rituximab

We describe a patient with neuro-Behçets disease (NBD) that presented with symptoms of raised intracranial pressure including papilloedema. MRI revealed tumour-like lesions which, on biopsy, confirmed an active vasculitis. Treatment was commenced with prednisone and cyclophosphamide which proved unsuccessful with enlargement of the cerebral mass lesions. Infliximab and mycophenolate were trialled also without benefit. The patient required ventriculoperitoneal shunts to relieve the symptoms of hydrocephalus. Rituximab was then commenced with significant symptomatic and imaging improvement. The case is unique, in our experience, in the need for shunting to relieve the symptoms of hydrocephalus related to vasculitis.
