hypermetropia |
Farsightedness or hyperopia occurs when a refractive error in which light rays entering the eye are focused behind the retina. This condition is easily corrected with corrective lenses or contact lenses. (27 Sep 1997) |
hypermetropy |
A condition of the eye in which, through shortness of the eyeball or fault of the refractive media, the rays of light come to a focus behind the retina; farsightedness; called also hyperopia. Cf. Emmetropia. In hypermetropia, vision for distant objects, although not better absolutely, is better than that for near objects, and hence, the individual is said to be farsighted. It is corrected by the use of convex glasses. Hypermetrop"ic. Origin: NL. Hypermetropia, fr. Gr. Excessive +, the eye. See Hypermeter. Source: Websters Dictionary (01 Mar 1998) |

hypermobility |
Increased range of movement of joints, joint laxity, occurring normally in young children or as a result of disease, e.g., Marfan's or Ehlers-Danlos syndrome; hypermobility may result in degenerative joint disease. (05 Mar 2000) |
hypermobility syndrome |
<syndrome> A common benign childhood condition involving hypermobile joints (that can move beyond the normal range of motion). Symptoms include pains in knees, fingers, hips, and elbows. The affected joints may sprain or dislocate. Scoliosis (curvature of the spine) is more frequent. Usually improves with adulthood. Also called the joint hypermobility syndrome. (12 Dec 1998) |

hypermutable phenotype |
<molecular biology> A bacterial strain with the hypermutable phenotype is one which is unable to replace uracil (a nucleotide normally found only in RNA) with cytosine in its DNA when the uracil appears in the DNA by mistake. As a result, the strain undergoes much higher rates of mutation than other bacterial strains. (11 Jan 1998) |
hypermyotonia |

hypermyotrophy |
Muscular hypertrophy. Origin: hyper-+ G. Mys, muscle, + trophe, nourishment (05 Mar 2000) |
hypernatraemia |
<biochemistry> Abnormal elevation of blood sodium concentration. Normal blood sodium should be 136 to 142 milliequivalents per litre. Excessively high blood sodium (155+meq/l) can manifest as a decreased level of consciousness or a change in mentation. Origin: Gr. Haima = blood (11 Jan 1998) |
hypernatraemic encephalopathy |
Subarachnoid and subdural effusions in infants with hypernatraemic dehydration. (05 Mar 2000) |
hyperneocytosis |
Hyperleukocytosis in which there are considerable numbers of immature and young cells (especially in the granulocytic series); i.e., a "shift to the left" in the haemogram. Synonym: hyperskeocytosis. Origin: hyper-+ G. Neos, new, + kytos, cell, + -osis, condition (05 Mar 2000) |

hypernephroma |
<oncology, tumour> The most common form of kidney cancer which occurs when the cells lining the renal tubule undergo cancerous changes. There are approximately 18,000 new cases of renal cell carcinoma (hypernephroma) per year in the U.S. With about 8,000 deaths annually. Smoking is considered a major risk factor. Kidney dialysis patients are at increased risk for the development of hypernephroma. Family history for renal cell carcinoma is also considered a risk factor. Symptoms include haematuria, flank pain, abdominal pain, back pain, weight loss and abdominal swelling. (27 Sep 1997) |
