Derby shoe. A derby (pronounced /ËdÉËrbi/ DAR-bee or in North American English /ËdÉËrbi/ DUR-bee; also called gibson) is a style of boot or shoe characterized by quarters with shoelace eyelets that are sewn on top of the vamp.

Dengue is an infectious disease caused by dengue viruses, which are transmitted to humans by mosquitoes. The rising level of dengue infections has become a serious international concern.
Dengue fever can also cause bleeding from the skin, nose, and gums. Recovery from dengue fever is often lengthy, lasting several weeks, and patients can experience lingering fatigue and depression. Infection with the dengue virus can also cause a disease called severe dengue, which is more serious than dengue fever. Although the early symptoms of severe dengue are similar to dengue fever, severe dengue has a much higher death rate.
