| diabetic neuropathy | <neurology, pathology> Long standing or poorly controlled diabetes can cause permanent peripheral and autonomic nerve dysfunction known as diabetic neuropathy. Origin: Gr. Pathos = disease (27 Sep 1997) |
|---|---|
| diabetic patient | Diabetes mellitus is a disorder that is caused by the insufficient production of the pancreatic hormone insulin. Without insulin cells are unable to absorb glucose, necessary for cellular metabolism and energy production. Patients may have type I diabetes (juvenile onset) or type II diabetes (adult onset). Individuals with either condition are considered to be diabetic. (27 Sep 1997) |
| diabetic polyneuropathy | A distal, symmetrical, generally sensorimotor polyneuropathy that is a frequent complication of diabetes mellitus. (05 Mar 2000) |
| diabetic puncture | A puncture at a point in the floor of the fourth ventricle of the brain which causes glycosuria. Synonym: Bernard's puncture. (05 Mar 2000) |
| diabetic retinitis | See: diabetic retinopathy. (05 Mar 2000) |
| diabetic retinopathy | <ophthalmology, pathology> A major cause of blindness in diabetics. Retinal disease results from adverse effects on the blood vessels which supply the retina. Swollen retinal vessels which leak fluid into the retina are commonly seen on physical examination of the eyes. Poorly controlled insulin dependent diabetes and/or hypertension are the major risk factors. Symptoms include decreased vision and colour perception. Origin: Gr. Pathos = disease (27 Sep 1997) |
| Arneth formula | The normal, approximate ratio of polymorphonuclear neutrophils, based on the number of lobes in the nuclei, as follows: 1 lobe, 5%; 2 lobes, 35%; 3 lobes, 41%; 4 lobes, 17%; 5 lobes, 2%. (05 Mar 2000) |
| Bazett's formula | A formula for correcting the observed Q-T interval in the electrocardiogram for cardiac rate: corrected Q-T = Q-T sec/✓R -R sec. (05 Mar 2000) |
| Bernhardt's formula | <nutrition> A formula used to calculate the ideal weight, in kilograms, for an adult; it is the height in centimeters times the chest circumference in centimeters divided by 240. (14 Aug 2000) |
| Black's formula | A translation of Pignet's formula into British measurements: F = (W + C) -H; F is the empirical factor, W is the weight in pounds, C the chest girth in inches at full inspiration, and H the height in inches; a man is classed as very strong when F is over 120, strong between 110 and 120, good 100 to 110, fair 90 to 100, weak 80 to 90, very weak under 80. (05 Mar 2000) |
| Broca's formula | A fully developed man (30 years old) should weigh as many kilograms as he is centimeters in height over and above 1 meter. (05 Mar 2000) |
| Van Slyke's formula | The value obtained when the square root of the urine flow (when below 2 ml/min) is multiplied by the urine urea concentration and divided by the whole blood urea concentration; represents an old empirical adjustment for the effect of low urine flow on urea excretion; sometimes corrected for body size by dividing by some function of body weight or surface area. Later, plasma concentration was substituted for blood concentration in the calculation. The normal value is about 54 ml/min per 1.73 m2 in an adult person. Synonym: Van Slyke's formula. (05 Mar 2000) |
| Mall's formula | A formula for determining the age (in days) of a human embryo; calculated as the square root of its length (measured from vertex to breech) in millimeters multiplied by 100. (05 Mar 2000) |
| Ranke's formula | A = grams of albumin per liter of a serous fluid: then, A = (sp. Gr. -1000) × 0.52 -5.406. (05 Mar 2000) |
| rational formula | In chemistry, a formula that indicates the constitution as well as the composition of a substance. (05 Mar 2000) |
