Treatment of Acute Delirium in a Patient with Parkinson's Disease by Transfer to the Intensive Care Unit and Administration of Dexmedetomidine.

The treatment of delirium or psychosis in patients with Parkinson's disease (PD) can be complicated by the limited number of pharmacological agents that can be used in this population. Typical and atypical antipsychotics are contraindicated, as they can worsen motor symptoms. The treatment of acute delirium is even more complicated in the hospital setting, as many medications deemed safer in this population are only available in oral form.

Diabetes-enhanced tumor necrosis factor-alpha production promotes apoptosis and the loss of retinal microvascular cells in type 1 and type 2 models of diabetic retinopathy.

Retinal microvascular cell loss plays a critical role in the pathogenesis of diabetic retinopathy. To examine this further, type 1 streptozotocin-induced diabetic rats and type 2 Zucker diabetic fatty rats were treated by intravitreal injection of the tumor necrosis factor-specific inhibitor pegsunercept, and the impact was measured by analysis of retinal trypsin digests. For type 2 diabetic rats, the number of endothelial cells and pericytes positive for diabetes-enhanced activated caspase-3 decreased by 81% and 86%, respectively, when treated with pegsunercept (P < 0.
