Dirofilaria repens in the eyelid:case report of subcutaneous manifestation

PURPOSE. The authors report a case of eyelid subcutaneous filariasis. METHODS. Thorough history, eye examination, surgical intervention, and parasitologic analysis. RESULTS. An adult Dirofilaria repens worm was extracted from the right upper eyelid in a man living in Italy presenting to our department with lid swelling. CONCLUSIONS. Due to increasing migration of populations to Europe, rare manifestations of ocular filariasis are becoming more common. Surgery was both diagnostic and therapeutic.

All-optical techniques enabling packet switching

Scalability of packet switched cross-connects that utilize all-optical signal processing is a crucial issue that eventually determines the future role of photonic signal processing in optical networks. After reviewing several labeling techniques, we discuss in this talk label stacking techniques and its benefits for scalable optical burst and packet switched nodes. All-optical signal processing techniques enabling label stacked processing and all-optical devices for ultrafast packet switching will be also presented
