    Evolution of peripheral vs metabolic perfusion parameters during septic shock resuscitation. A clinical-physiologic study
    (W B SAUNDERS CO-ELSEVIER INC, 2012) Hernandez, Glenn; Pedreros, Cesar; Veas, Enrique; Bruhn, Alejandro; Romero, Carlos; Rovegno, Maximiliano; Neira, Rodolfo; Bravo, Sebastian; Castro, Ricardo; Kattan, Eduardo; Ince, Can
    Purpose: Perfusion assessment during septic shock resuscitation is difficult and usually complex determinations. Capillary refill time (CRT) and central-to-toe temperature difference (Tc-toe) have been proposed as objective reproducible parameters to evaluate peripheral perfusion. The comparative evolution of peripheral vs metabolic perfusion parameters in septic shock resuscitation has not been studied. We conducted a prospective observational clinical-physiologic study to address this subject.

    Optimal length of triple therapy for H pylori eradication in a population with high prevalence of infection in Chile
    (BAISHIDENG PUBLISHING GROUP INC, 2007) Riquelme, Arnoldo; Soza, Alejandro; Pedreros, Cesar; Bustamante, Andrea; Valenzuela, Felipe; Otarola, Francisco; Abbott, Eduardo; Arellano, Marco; Medina, Brenda; Pattillo, Alejandro; Greig, Douglas; Arrese, Marco; Rollan, Antonio
    AIM: To compare the efficacy of 7-d versus 14-d triple therapy for the treatment of H pylori infection in Chile, with a prevalence of 73% in general population. METHODS: H pylori-infected patients diagnosed by rapid urease test, with non-ulcer dyspepsia or peptic ulcer disease were randomized to receive omeprazole 20 mg bid, amoxicillin 1 g bid, and clarithromycin 500 mg bid for 7 (OAC7) or 14 (OAC14) d. Primary outcome was eradication rate 6 wk after the treatment. Subgroup analysis was carried out considering the eradication rate among patients with or without peptic ulcer disease and eradication rate among smokers or non-smokers.
