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.
A wart is typically a small, rough, non-cancerous tumor that grows on the top layer of skin. They often resemble a solid blister or a cauliflower, and can seem either very light or very dark compared to the normal skin surrounding it. They're usually painless, but can cause itching and burning if they are in high-friction areas.
