Comparative Study Clinical TrialTriage of patients with acute gastrointestinal bleeding for intensive care unit admission based on risk factors for poor outcome.
This study's aim was to determine the prognostic factors and to develop a triage system for intensive care unit (ICU) admission of patients with gastrointestinal bleeding (GIB). This prospective, observational study included 411 adults consecutively hospitalized for GIB. Each patient's selected clinical findings and laboratory values at presentation were obtained. ⋯ End-organ dysfunction, active bleeding, hepatic cirrhosis, and high APACHE II scores were independent predictors of poor outcome with odds ratios of 3:1, 3:1, 2:3, and 1:1, respectively. The ICU admission rate was 37%. High APACHE II score, active bleeding, end-organ dysfunction, and hepatic cirrhosis are independent predictors of poor outcome in patients with GIB and can be used in the triage of these patients for ICU admission.

Randomized Controlled Trial Comparative Study Clinical TrialSulpiride versus metoclopramide in nononcologic patients with vomiting or nausea.
Metoclopramide, a benzamide substitute, is used frequently as an antiemetic drug. Sulpiride, another benzamide substitute, was investigated and found to be safe and effective in a handful of studies involving only oncologic or other severely symptomatic patients. In this investigation the authors compared prospectively the antiemetic efficacy of sulpiride versus metoclopramide in a double-blind, randomized study involving 36 nononcologic patients with transient vomiting or nausea of various etiologies. ⋯ Efficacy of the two drugs proved similar, and at the end of the study, 14 and 13 of 18 patients on sulpiride or metoclopramide respectively were asymptomatic. Only transient, minor side effects were reported in one patient in each group. The authors conclude that sulpiride is an effective and safe antiemetic drug that can be adopted legitimately in such cases as a first choice, or serve as an equipotent alternative to metoclopramide in patients sensitive to the latter.

Randomized Controlled Trial Clinical TrialPharmacokinetic interaction between acetaminophen and lansoprazole.
Because of its minimal gastric toxicity, acetaminophen is the analgesic of choice for patients with gastric acid-related disorders. Because proton pump inhibitors are widely used, concomitant prescription of acetaminophen and lansoprazole would be prevalent. This crossover study was conducted to investigate an acetaminophen-lansoprazole interaction. ⋯ The peak plasma concentration of acetaminophen and the time to its occurrence were significantly higher and shorter, respectively, during the lansoprazole session than during the control session. Neither the elimination half-life nor the area under the curve was significantly different between the two sessions. Lansoprazole hastens the absorption of acetaminophen solution, but little modifies its elimination rate and bioavailability.

Nine hundred seventy-nine cases of pill esophagitis due to nearly 100 different medications are reviewed. Pill-induced injuries occur when caustic medicinal pills dissolve in the esophagus rather than passing rapidly into the stomach as intended. Most patients suffer only self-limited pain, but esophageal hemorrhage, stricture, and perforation may occur, and fatal injuries have been reported. The incidence of this iatrogenic injury can be reduced but not eliminated by emphasizing the importance of taking pills while upright and with plenty of fluids.

Safety of endoscopic procedures has been a major issue over the last 10 years. Outbreak of new infectious diseases (type C) hepatitis, Creutzfeldt-Jakob disease) underlines the necessity for strengthening cleaning and disinfection guidelines. ⋯ Improvements from a hygienic point of view of both endoscopes and washer-disinfectors are important goals for manufacturers. Adequate training of endoscopic staff is one of the most crucial points to achieve the highest quality control standards in digestive endoscopy.
