Gastrointestinal dysmotility complicating Behçet's syndrome: description of a newly recognised clinical phenotype.

Objectives: Gastrointestinal dysmotility may arise in a variety of auto-immune and auto-inflammatory diseases and hitherto has not been described in Behçet's syndrome (BS).

Methods: We present data on a cohort of seven patients under our care who presented with symptoms of and investigations compatible with an immune associated disorder of gastrointestinal motility, or enteric neuropathy.

Results: We describe the clinical features and investigation results.

Alternative male mating tactics of the endemic Red Sea parrotfish Scarus ferrugineus.

The present study shows that small non-territorial terminal-phase males of the rusty parrotfish Scarus ferrugineus are reproductively active and are comparable with initial-phase males in behaviour, rates of participation during group-spawning and success in streaking into pair spawning. Large territorial terminal-phase males defend contiguous territories for several hours during the morning where they pair spawn with initial-phase females.
