Hypoventilation may be caused by an uneven distribution of inspired air (as in bronchitis), obesity, neuromuscular or skeletal disease affecting the thorax, decreased response of the respiratory center to carbon dioxide, or a reduced amount of functional lung tissue, as in atelectasis, emphysema, and pleural effusion.
Seborrheic Keratosis Causes Wart Like Skin Growths. Seborrheic keratosis causes wart like skin growths to appear on just about every body thatâs over age 40. Although they resemble skin cancer, these keratosis tumors are benign.
Warts are non-cancerous skin growths caused by a viral infection in the top layer of the skin. The common wart is a small, hard, rough bump that usually occurs on the hands and fingers, but they can be flat and smooth. Salicylic acid softens the skin layers that form the wart so that they can be rubbed off.
