Alternative name(s): bacterial labyrinthitis; serous labyrinthitis
Definition: An ear disorder involving inflammation of the canals of the inner ear (semicircular canals, labyrinth), resulting in dizziness.
Lack of intrinsic factor
Alternative name(s): Addisonian (juvenile) lack of intrinsic factor; congenital lack of intrinsic factor
Definition: An absence of a natural substance normally present in the stomach and essential to the digestion of vitamin B-12. Lack of intrinsic factor leads to pernicious anemia and vitamin B-12 deficiency.
Congenital lack of intrinsic factor causes inadequate absorption of vitamin B-12 starting around 6 months of age, while the juvenile type tends to manifest itself at an age greater than 10 years. There is an autosomal recessive inheritance pattern suggested in the congenital form.
Lacrimal gland tumor
Definition: A tumor in the glands that secrete tears. These two glands are located above and to the side of each eye. The tumor can be benign or malignant (cancer).
Definition: Lactic acidosis occurs when lactic acid accumulates in the blood stream at a faster rate than it can be eliminated. Lactic acid is produced in the presence of decreased oxygen. The most common cause of increased lactic acid is intensive exercise in which the body builds up an oxygen debt.
Alternative name(s): myasthenic syndrome
Definition: A condition characterized by muscle weakness that improves with continued contraction of the muscle.
Definition: A rare inherited skin condition of the newborn in which scaly plate-like layers of skin are shed (desquamated).
Laryngeal nerve damage
Definition: Damage to one of the pair of nerves attached to the larynx (voice box). This can result in loss of voice or obstruction to breathing. Damage to the recurrent laryngeal nerve is especially common during heart surgery and/or chest surgery. In infants and children, injury to this nerve is often manifested by a weak cry or a hoarse voice.
Definition: Inflammation of the larynx generally associated with hoarseness or loss of voice.
Alternative name(s): surgery using laser

Lateral collateral ligament (LCL) injury
Alternative name(s): knee injury - lateral collateral ligament; injury - knee - LCL; injury - LCL; injury - lateral collateral ligament
Definition: An injury to the lateral collateral ligament (LCL), a ligament extending from the top-outside surface of the fibula to the bottom-outside surface of the femur. The ligament prevents the knee joint from side-to-side (lateral) instability. Sports injuries that produce LCL tears in children are also very likely to produce breaks (called epiphyseal fractures) in the "growing part" of the thigh bone (femur) or shin bone (tibia).
First degree lateral collateral ligament (LCL) injury
Second or third degree lateral collateral ligament (LCL) injury
