First nosocomial outbreak of SME-4-producing Serratia marcescens in South America.

Carbapenemase-producing-Serratia marcescens isolates, although infrequent, are considered important nosocomial pathogens due to their intrinsic resistance to polymyxins, which limits therapeutic options. We describe a nosocomial outbreak of SME-4-producing S. marcescens in Buenos Aires city which, in our knowledge, represents the first one in South America.

[Functional Dyspepsia and infection by Helicobacter pylori: a causal relation does not exist].

Unlabelled: The role of Helicobacter pylori (Hp) in Non Ulcer Dyspepsia (NUD) has been a controversial issue.

Objectives: 1) To determine the frequency of Upper Gastrointestinal Endoscopy (UGE) in patients suffering NUD in whom endoscopy was indicated in our Service, 2) To determine the prevalence of infection by Hp in patients with NUD in whom endoscopy was done, 3) To find an association of clinical and historical facts among patients with and without Hp infection.

Population And Sample: 91 consecutive patients, free of esophageal or gastro-intestinal organic disease by endoscopic criteria from a total of 132, in a period of six months.

[History of patients with pelvic floor dysfunction].

Objectives: 1) To determine differences between sexes; 2) To determine differences by sex and age groups in symptom onset, time of evolution, clinical forms and probable associated causes.

Population And Sample: 83 consecutive patients with diagnosed PCP (X age = 50.9 SE 2.

[Esophageal sensitivity. Projection of esophageal pain induced by balloon distension].

Unlabelled: The esophagus is source of several kinds of painful sensibility. Esophageal sensoriality follows the general visceral sensibility laws with some individual differences. We have investigated the areas of pain projection induced by a progressive balloon distension in 2 cm scales from 38 to 22 cm.
