| external respiratory nerve of Bell | <anatomy, nerve> Arises from the fifth, sixth, and seventh cervical nerves (roots of brachial plexus), descends the neck behind the brachial plexus, and is distributed to the serratus anterior muscle; it is somewhat unusual in that it courses on the superficial aspect of the muscle is supplies; its paralysis results in "winged scapula".

| Krause's respiratory bundle | A slender, compact fibre bundle extending longitudinally through the dorsolateral region of the medullary tegmentum, surrounded by the nucleus of the solitary tract, below the obex decussating over the central canal, and descending over some distance into the upper cervical segments of the spinal cord. It is composed of primary sensory fibres that enter with the vagus, glossopharyngeal, and facial nerves, and in part convey information from stretch receptors and chemoreceptors in the walls of the cardiovascular, respiratory, and intestinal tracts; in rostral parts of the tract impulses are generated by the receptor cells of the taste buds in the mucosa of the tongue. Its fibres are distributed to the nucleus of the solitary tract. Synonym: tractus solitarius, fasciculus rotundus, fasciculus solitarius, funiculus solitarius, Gierke's respiratory bundle, Krause's respiratory bundle, round fasciculus, solitary bundle, solitary fasciculus.

| lower respiratory tract smear | A group of cytologic specimens containing material from the lower respiratory tract and consisting mainly of sputum (spontaneous, induced) and material obtained at bronchoscopy (aspirated, lavaged, brushed); used for cytologic study of cancer and other diseases of the lungs. Synonym: bronchoscopic smear, sputum smear. (05 Mar 2000) |

Chronic diseases can interfere with red blood cell production in addition to shortening red blood cell life span in the body. Symptoms are largely due to the underlying disease. Haemoglobin and haematocrit are generally low. Iron studies may be low to normal. Red blood cell indices may usually normal. (27 Sep 1997) |
| benign familial chronic pemphigus | Recurrent eruption of vesicles and bullae that become scaling and crusted lesions with vesicular borders, predominantly of the neck, groin, and axillary regions; autosomal dominant inheritance, presenting in late adolescence or early adult life. Synonym: Hailey-Hailey disease. (05 Mar 2000) |
| candidiasis, chronic mucocutaneous | A clinical syndrome characterised by development, usually in infancy or childhood, of a chronic, often widespread candidiasis of skin, nails, and mucous membranes. It may be secondary to one of the immunodeficiency syndromes, inherited as an autosomal recessive trait, or associated with defects in cell-mediated immunity, endocrine disorders, dental stomatitis, or malignancy. (12 Dec 1998) |
| granulomatous disease, chronic | A recessive x-linked defect of leukocyte function in which phagocytic cells ingest but fail to digest bacteria, resulting in recurring bacterial infections with granuloma formation. (12 Dec 1998) |
| persistent chronic hepatitis | A benign chronic hepatitis that may follow acute viral hepatitis A or B, or complicate bowel diseases; after six months, liver biopsy changes are mild, unlike active chronic hepatitis; rarely, if ever, progresses to cirrhosis, portal hypertension, or liver failure.
