Definitive laceration management depends. on the time since injury, the extent and loca-. tion of the wound, available laceration repair. materials, and the skill of the physician. Guidelines for seeking surgical consultation. for laceration repair are presented in Table 1. The optimal time interval from injury to. laceration repair is not clearly defined.

This gene on chromosome 2 codes for the enzyme lactase. This enzyme enables infants to break down lactose, the main sugar in milk. In people who are lactose tolerant, the gene remains active throughout their lives.In most people who are lactose intolerant, the gene is turned off after infancy, making the digestion of dairy products difficult and painful.his enzyme enables infants to break down lactose, the main sugar in milk.

Lactose intolerance is the inability to break down a type of natural sugar called lactose. Lactose is commonly found in dairy products, such as milk and yogurt. A person becomes lactose intolerant when his or her small intestine stops making enough of the enzyme lactase to digest and break down the lactose. When this happens, the undigested lactose moves into the large intestine. The bacteria that are normally present in the large intestine interact with the undigested lactose and cause symptoms such as bloating, gas, and diarrhea. The condition may also be called lactase deficiency.
