Otitis externa no more than 4 to 7 days. The ear should be left open. It is imperative that visualization of an intact tympanic membrane (eardrum) is noted. Use of certain medications with a ruptured tympanic membrane can cause tinnitus, vertigo, dizziness and hearing loss in some cases. Otitis externa responds well to treatment, but complications may occur if it is not treated. Individuals with underlying diabetes, disorders of the immune system, or history of radiation therapy to the base of the skull are more likely to develop complications, including malignant otitis externa. In these individuals, rapid examination by an otolaryngologist (ear,
Translocase of the outer membrane Translocase of the outer membrane The translocase of the outer membrane (TOM) is a complex of proteins found in the outer mitochondrial membrane of the mitochondria. It allows movement of proteins through this barrier and into the intermembrane space of the mitochondrion. Most of the proteins needed for mitochondrial function are encoded by the nucleus of the cell. The outer membrane of the mitochondrion is impermeable to large molecules greater than 5000 Daltons. The TOM works in conjunction with the translocase of the inner membrane (TIM) to translocate proteins into the mitochondrion. Many of the proteins in the TOM complex,
