Iron deficiency anemia, esophageal webs, and dysphagia (difficulty swallowing). The iron deficiency is typically chronic and severe.

Proteolipid protein: Abbreviation: PLP. Also called lipophilin. The most abundant protein of myelin, the covering and insulation around nerves. The gene PLP1 that codes for PLP is on the X chromosome. Mutations in PLP cause Pelizaeus-Merzbacher disease (PMD), an X-linked recessive disorder characterized by loss of myelin. PMD causes nystagmus (rhythmical oscillation of the eyeballs), psychomotor developmental delay, tremor, spasticity (increased muscular tone), and ataxia (wobbliness).…

Inflammation of the pleura which may be caused by infection, injury or tumor. When the pleura becomes inflamed, it can produce more than the normal amount of fluid, causing a pleural effusion.

Pertaining to the pleura, the thin covering that protects the lungs. The term “pleural” is pronounced like “plural” (but does not have plural meanings).

One of the two membranes around the lungs. These two membranes are called the visceral and parietal pleurae. The visceral pleura envelops the lung, and the parietal pleura lines the inner chest wall. There is normally a small quantity (about 3 to 4 teaspoons) of fluid that is spread thinly between the visceral and parietal pleurae. The pleural fluid acts as a lubricant between the two…
