The American College of Gastroenterology's 2016 clinical guidelines for treating lower gastrointestinal (GI) tract bleeding recommends evaluating of nasogastric tube aspiration and the ratio of blood urea nitrogen (BUN) to creatinine to differentiate upper from lower GI bleeds. There is no simple and rapid test available to predict the outcome of an early pregnancy complicated by vaginal bleeding. In this prospective study, 15 women with normal pregnancies collected a weekly urine sample between 6 and 13 weeks' gestation. A single random urine sample was obtained from 15
BACKGROUND
Impaired kidney function has been linked to both ischemic events as well as bleeding complications in several clinical conditions. Our aim was to investigate if cystatin C, creatinine and calculated glomerular filtration rate (eGFR) were related to future risk of bleeding complications,
This study was conducted to evaluate the blood urea nitrogen/creatinine (BUN/Cr) ratio for distinguishing an upper versus lower source of gastrointestinal (GI) bleeding. Charts of patients who presented to the emergency department (ED) with the diagnosis of GI bleeding from August 1995 to August
BACKGROUND
The blood urea nitrogen to creatinine ratio (BUN/CREAT) is believed to reliably discriminate upper gastrointestinal bleeding (UGIB) from lower gastrointestinal bleeding (LGIB). However, studies evaluating subsets of bleeders in whom this ratio may have real diagnostic utility are
OBJECTIVE
The aims of our study were to evaluate the blood urea nitrogen to creatinine ratio (BUN/Cr ratio) for distinguishing between an upper and lower gastrointestinal bleeding (GIB), and differentiating between the two most common causes of upper gastrointestinal bleeding (UGIB) presenting with
Serum urea/creatinine (Ur/Cr) ratios were determined in patients showing massive gastrointestinal (GI) bleeding in order to evaluate the bleeding site. In 36 cases of upper GI bleeding, serum Ur/Cr ratios were 119.1 +/- 4.0. The ratios were 54.1 +/- 12.1 and 58.4 +/- 10.3 in 23 cases of lower GI
In patients with gastrointestinal hemorrhage, delayed or late scans with Tc-99m labeled red blood cells are readily performed and have prognostic impact when early images are negative. Nevertheless, there have been no indicators for the likelihood of detecting bleeding on such images. In a review of
Blood urea nitrogen (BUN) and serum creatine concentrations were recorded from the medical records of 52 dogs with clinical evidence for upper gastrointestinal hemorrhage (UGH) at the Colorado State University Veterinary Teaching Hospital between 1988 and 1995. Eighteen of the dogs had melena, 11
Localizing the bleeding site in pediatric patients with gastrointestinal hemorrhage may require invasive and costly diagnostic procedures. A simple index to discriminate upper and lower bleeding sources would be invaluable. We evaluated the reliability of the calculated blood urea
OBJECTIVE
The aim of this study was to examine the hypothesis that patients with non-traumatic subarachnoid hemorrhage (SAH) have statistically significant subnormal creatinine levels and that the creatinine levels are associated with severity of disease.
METHODS
This was a retrospective
Gastrointestinal bleeding constitutes a third part of the hospitalizations in our service. Some times is difficult to clinically distinguish the site of bleeding. It was pointed that the urea/creatinine ratio can help to define the site of bleeding, but there is a lot of superposition in the
The urea/creatinine-ratio has been proposed as an instrument for differentiating upper from lower gastrointestinal haemorrhages. The predictability of this method was investigated in 105 cases with the source of bleeding to be in the upper gastrointestinal tract and in 31 cases in the lower
Symptomatic intracranial hemorrhage (sICH) is a known complication following administration of intravenous tissue plasminogen activator (IV tPA) for acute ischemic stroke. sICH results in high rates of death or long-term disability. Our ability to predict its occurrence is important in clinical
The predictive value of a urea/creatinine ratio > or = 100 for indicating upper gastrointestinal bleeding was evaluated in 78 consecutive patients with a history of gastrointestinal bleeding 24 hours or less before admission. Serum beta-2-microglobulin was measured to elucidate whether renal
