The eye worm, a parasite that lives in humans and other primates. People contract the parasite when bitten by infected deer flies. The larvae of the worm enter the bloodstream and later develop into adult worms. Symptoms may not appear for months or years after the bite of the fly. The worms migrate through the skin causing local inflammatory reactions called Calabar swellings. The worms can often be seen migrating across the conjunctiva and cornea of the eye. Hence, the name “eye worm.” The worm sometimes enters the brain causing encephalitis. The microfilarial (tiny thread-like) form of the worm is found in blood and lymphatic fluid during the day and in the lungs at night. The insect vector (that carries the parasite) is the deer fly Chrysops which lives in swampy areas of the forest, principally in the Congo River region, Sudan, and Ethiopia. Diagnosis is by detection of the microfilariae in the blood. Protective measures against the flies include the use of a repellent, long-sleeved shirts and long pants, and the use of bednets when sleeping. Treatment is with diethylcarbamazine (DEC) or ivermectin (Stromectol). DEC can also be used for prophylaxis. The disease caused by loa loa is called loiasis or lymphatic filariasis.
Having to do with a lobe. For example, lobar pneumonia is pneumonia in a single lobe of a lung.
Part of an organ that appears to be separate in some way from the rest. A lobe may be demarcated from the rest of the organ by a fissure (crack), sulcus (groove), connective tissue or simply by its shape. For example, there are the frontal, parietal, temporal, and occipital lobes of the brain. The word […]
An operation to remove an entire lobe of the lung.

- Lobstein's disease
Osteogenesis imperfecta type I. An inherited, generalized connective tissue disorder featuring bone fragility and blue sclerae (blue whites of the eyes). The classic mild form of “brittle bone disease.” It is a dominant trait with males and females affected. One copy of the mutant gene is sufficient to cause the disease. Clinically it is characterized […]
