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 can appear at any age but are more common in older children and are uncommon in the elderly. A wart's appearance varies with its location and the type of virus that has caused it. For example, flat warts commonly appear on the face, neck, chest, forearms and legs. Most warts go away after a year or two, but some last for years or come back after going away. Warts can itch or bleed.
