Review Case Reports
Optic disc oedema and diabetes mellitus: a case report with review.
Optic disc oedema is a neurological complication of diabetes mellitus. Typically, the patient is a young diabetic with minimal symptomatology but severe bilateral optic disc oedema discovered on routine eye examination. It is a relatively benign condition which on occasion can result in a residual visual deficit, but requires no specific intervention and represents a subgroup of anterior ischaemic optic neuropathy (AION). We present a patient with insulin dependent diabetes and asymptomatic bilateral optic disc oedema, with a brief review of the syndrome and its pathogenesis.

We report two cases of heparin induced thrombocytopenia (HIT), in patients who required anticoagulation for extracorporeal procedures (haemodialysis and cardiopulmonary bypass) one associated with recurrent thrombosis of the artificial circuits. Resolution of thrombocytopenia and successful anticoagulation were achieved using a low molecular weight heparinoid (LMWH) Org 10172. Anticoagulation was monitored using estimations of plasma anti-factor Xa activity. These cases demonstrate that LMWH provides safe and effective anticoagulation in patients in whom unfractionated heparin has caused HIT.

Coeliac plexus block is a safe procedure with relatively few side-effects. We report two cases of persistent severe diarrhoea following coeliac plexus block and explore the possible reasons for this previously unrecognised side-effect. We postulate that somatostatin analogue may be useful as treatment for diarrhoea following neurolytic coeliac plexus block that is unresponsive to conventional anti-diarrhoeal agents.
