often inaccurate. The sensitivity of the human eye in interpreting large numbers of images decreases with increasing number of cases‚ particularly when only a small number of those images shows abnormalities. Therefore‚ it is useful to construct computer systems to aid early diagnosis of breast cancer with mammography. An automated computer system could evaluate all mammograms and point out the areas which are detected as abnormal. Ideally‚ if the sensitivity and specificity of the computer system

The negative predictive values of white cell count and C-reactive protein for acute appendicitis were 28% and 50%‚ respectively. Sensitivity of the ultrasound to detect acute appendicitis was 60% with a negative predictive value of 31%; 30% of patients had complicated appendicitis. Histology results showed a normal appendix in 11% of patients. The 30-day mortality rate was 1.4%. Though

Preliminary research of the current prevalence and management patterns of speech and language disorders is necessary before more in-depth epidemiologic analyses may be undertaken. One source of data for this type of study is electronic medical records (EMR) extracted from primary care clinics themselves. . EMRs provide patient histories in the form of diagnoses‚ prescriptions‚ billing information‚ referrals laboratory testing and other information recorded by the attending physician. Thus‚ EMRs present

Four kinds of ELISA here are here illustrated as you may concern: Direct ELISA (1) Direct ELISAs involve attachment of the antigen to the solid phase‚ followed by an enzyme-labeled antibody. This type of assay generally makes measurement of crude samples difficult‚ since contaminating proteins compete for plastic binding sites. Indirect ELISA (2) Indirect ELISAs also involve attachment of the antigen to a solid phase‚ but in this case‚ the primary antibody is not labeled. An enzyme-conjugated

2- What is the application of isozymes in clinical diagnosis? Give the names of some enzymes used in diagnostic kits. Testing the serum content is a very useful tool in the clinical diagnosis in general. Normally the enzymes are present inside the cells and the enzyme activity in the serum is very low. As the tissue gets damaged‚ due to a disease or infection‚ enzymes can be released from the damaged cells into the serum. As enzymes are biological catalysts‚ the detection of the presence and the

Some risk factors for poor mental health in the post-partum period can be identified prenatally; however prenatal screening tools developed to date have had poor sensitivity and specificity. The objective of this study was to develop a screening tool that identifies women at risk of distress‚ operationalized by elevated symptoms of depression and anxiety in the post-partum period using information collected in the prenatal

Both are relatively straight forward and use seven criteria readily obtained in the setting and evaluation of mild TBI. A head-to-head comparison of the two found that they had equivalent sensitivity in determining the need for neurosurgical intervention‚ but the Canadian CT Head Rules had a far superior specificity (76.3% versus 12.1%).(47) Because the incidence of TBI is highest in age groups 0 to 4 and 15 to 24‚ there are often many more years of life expectance at stake.2 Therefore‚ the threshold
