| diarrhoea, antibiotic-induced | A bacterium called Clostridium difficile (C.difficile), one of the most common causes of infection of the large bowel (colon). Patients taking antibiotics are at particular risk of becoming infected with C. Difficile. Antibiotics disrupt the normal bacteria of the bowel, allowing C. Difficile bacteria (and other bacteria) to become established and overgrow the colon. Many persons infected with C. Difficile bacteria have no symptoms but can become carriers of the bacteria and infect others. In other people, a toxin produced by C. Difficile causes diarrhoea, abdominal pain, severe inflammation of the colon (colitis), fever, an elevated white blood count, vomiting and dehydration. In severely affected patients, the inner lining of the colon becomes severely inflamed (a condition called pseudomembranous colitis). Rarely, the walls of the colon wear away and holes develop (colon perforation), which can lead to a life-threatening infection of the abdomen. (12 Dec 1998) |
| transport antibiotic | A substance that makes biomembranes permeable to certain ions. (05 Mar 2000) |
| barotrauma, otic | See: Barotitis. (12 Dec 1998) |
| communicating branch of otic ganglion to auriculotemporal nerve | <anatomy, nerve> A branch of the otic ganglion joining the roots of the auriculotemporal nerve to convey postsynaptic parasympathetic fibres to the parotid gland. Synonym: ramus communicans ganglii otici cum nervo auriculotemporali. (05 Mar 2000) |
| communicating branch of otic ganglion to chorda tympani | A small branch of the otic ganglion conveying sensory fibres to the chorda tympani. Synonym: ramus communicans cum chorda tympani. (05 Mar 2000) |
| communicating branch of otic ganglion with medial pterygoid nerve | <anatomy, nerve> Branch of otic ganglion joining the nerve to the medial pterygoid muscle. Synonym: ramus communicans ganglii otici cum nervo pterygoideo mediali. (05 Mar 2000) |
| communicating branch of otic ganglion with meningeal branch of mandibular nerve | <anatomy, nerve> A branch of otic ganglion to the meningeal branch of mandibular nerve conveying postsynaptic parasympathetic fibres which run back to the main stem of the mandibular nerve for distribution to the parotid gland via the auriculotemporal nerve. Synonym: ramus communicans ganglii otici cum ramo meningeo nervi mandibularis. (05 Mar 2000) |
| otic | Relating to the ear. Origin: G. Otikos, fr. Ous, ear (05 Mar 2000) |
| otic abscess | A cerebral abscess usually involving the temporal lobe or cerebellar hemisphere, due to extension of suppuration of the middle ear. Synonym: otogenous abscess. (05 Mar 2000) |
| otic barotrauma | Middle ear problems due to changing atmospheric pressures, as when a plane descends to land. The problems include ear pain, ringing, diminished hearing and, sometimes, dizziness. Alternate terms include aerotitis: aerotitis media, barotitis, barotitis media. (12 Dec 1998) |
| otic capsule | The cartilage capsule surrounding the inner ear mechanism; in elasmobranchs, it remains cartilaginous in the adult; in the embryos of higher vertebrates, it is cartilaginous at first but later becomes bony (at approximately 23 weeks in humans). (05 Mar 2000) |
| otic ganglion | An autonomic ganglion situated below the foramen ovale medial to the mandibular nerve; its postganglionic, parasympathetic fibres are distributed to the parotid gland. Synonym: ganglion oticum, Arnold's ganglion, auricular ganglion, otoganglion. (05 Mar 2000) |
| otic pits | Paired depressions, one on either side of the head of the embryo, marking the location of the future auditory vesicles. Synonym: otic pits. (05 Mar 2000) |
| otic placodes | Paired ectodermal placode's that sink below the general level of the superficial ectoderm to form the auditory vesicles. Synonym: otic placodes. (05 Mar 2000) |
