abstract background: clinical risk index of babies (crib), score for neonatal acute physiology (snap), an update of the clinical risk index for babies score (crib ii) and score for neonatal acute physiology - perinatal extension (snap-pe) are scoring devices developed in neonatal intensive care units. this study reviewed these scoring systems in critically ill neonates to determine how well the...

background in 1996, donovan and colleagues represented a scoring system for better prediction of hirschsprung disease (hd). objectives our objective was to devise another scoring system that uses a checklist of radiologic and clinical signs to determine the probability of hd in suspicious patients. patients and methods in a diagnostic accuracy study, 55 children with clinical manifestations of ...

background cystic fibrosis is a complex progressive disease which assessing its progression and severity is essential. for this purpose there are scoring systems available to evaluate the disease severity. objectives the aim of the present study was to determine the clinical status of cf patients using shwachman score system in the pediatric pulmonary ward of masih daneshvari hospital. patients...

in this retrospective study the recorded data from 75 dairies 2932 cows with papillomatous digital dermatitis “pdd” were considered and a simple scoring system for assessing cow cleanliness was used to determine whether hygiene scores were correlated with individual pdd cow. screening cows at the parlor by using a water hose method and verification the case following inspecting restrained cows ...

All regions of Earth’s biosphere that we have studied—the waters of Earth’s oceans, the soil beneath our feet, and even the air we breathe—teem with viruses. Viral particles are among the smallest biological entities on the planet, with the average viral particle measuring about 100 nm in length: a size so small that five thousand viruses, lined end to end, would fit across the thickness of a h...

background: to reduce the mortality and morbidity rates of cystic fibrosis (cf) patients, and to have an effective clinical management, it is important to monitor the progression of the disease. the aim of this study was to evaluate the progression of lung disease in cf patients by means of assessing the correlation of the ct scoring system with clinical status and pulmonary function test at th...
