Disease relevance of Hematemesis

• Patient symptoms may vary from abdominal or back pain with gastro-intestinal bleeding to just hematemesis or melena [1].
• The diagnosis is suggested by the triad of chronic dysphagia, hematemesis, and acute neurologic signs [2].
• According to our review of the literature, this is the first report of a patient with a large celiac arterial aneurysm who exhibited hematemesis from gastric varices [3].
• Fibronectin, platelet factor 4 and beta-thromboglobulin in endemic hepatosplenic schistosomiasis: relation to acute hematemesis [4].
• To address whether inherent somatostatin levels determined clinically evident disease severity (epg, hepatomegaly, splenomegaly, hematemesis, ascites), the mean somatostatin values of the inactive disease status group and severe morbidity group were compared [5].

High impact information on Hematemesis

• Because of recurrent hematemesis in spite of sclerosing therapy on two occasions, the beta antagonist propranolol was begun [6].
• To further investigate the relationship between piroxicam and gastrointestinal bleeding, a 14-month prospective case study was undertaken of all patients hospitalized in Tromso, Norway, for hematemesis, melena, or perforation [7].
• A comparison of aspirin and acetaminophen consumption in 346 matched pairs of patients with hematemesis and melena and general population control subjects has shown associations between intake of both drugs and bleeding [8].
• Thirty patients had the triad of vomiting, hematemesis and alcoholism [9].
• Hematemesis. American College of Radiology. ACR Appropriateness Criteria [10].

Chemical compound and disease context of Hematemesis

• At multivariate analysis, the presence of anti-HCV was independently associated with previous parenteral anti-schistosomal therapy, a history of hematemesis and seropositivity for anti-HBc [11].
• A 57-yr-old male on long-term steroid therapy presented with hematemesis, fever, and a retroperitoneal fluid collection [12].
• This study was undertaken to evaluate the effect of various cimetidine and ranitidine administration schedules on intragastric pH in patients with recent episodes of hematemesis [13].
• Hepatitis and hematemesis complicating nicotinic acid use [14].
• Oral atropine alone was effective in 11 cases, was converted to intravenous atropine in 2 cases, and was terminated in 1 case because of hematemesis [15].

Biological context of Hematemesis

• While the host modulates the course of the disease by developing a cell mediated immunity, ultimately the inflammation in the liver interferes with portal blood flow that may lead to portal hypertension, portal-systemic shunts and fatal hematemesis [16].

Anatomical context of Hematemesis

• We present here a case of sudden onset of wretching and vomiting after IV infusion of cis-platinum for recurrent carcinoma of the uterine cervix in which the patient had profuse hematemesis secondary to three posterior gastroesophageal tears requiring operative intervention after failure of nonsurgical management [17].

Gene context of Hematemesis

• METHODS: Ninety children (mean age 7.3 +/- 3.0 years) with portal hypertension [extra-hepatic portal venous obstruction (EHPVO) 83, cirrhosis 7] presenting with hematemesis and/or melena were subjected to EST using 3% phenol in water as sclerosant [18].

Analytical, diagnostic and therapeutic context of Hematemesis

• As a small amount of hematemesis occurred just after a percutaneous transhepatic portography was performed, emergency EIS was carried out, following which the serum total bilirubin level markedly increased, mainly with a direct fraction, until it reached 70 mg/dl [19].
