Background: Risk of recurrent bleeding from Helicobacter pylori-negative ulcers is greater than for H pylori ulcers, but to what degree is unknown. Objective: To determine the risk of rebleeding for peptic ulcers with and without associated H pylori infection. Design: Prospective cohort study in 1 institution over 7 years. Participants: 120 patients had H pylori-negative peptic ulcer bleeding a...

Herpes simplex virus (HSV) infection, though most commonly seen in the oral, perioral and genital areas, can occur anywhere on the body. After primary infection, HSV then establishes latency in sensory nerve ganglia and reactivates intermittently, precipitated by various factors. These reactivations may be recurrent and appear in a dermatomal distribution, mimicking herpes zoster, often leading...

Recurrent or persistent infection is the major manifestation of primary immunodeficiency, which also results in atypical infection with opportunistic organisms. Young children are also vulnerable to infection and recurrent infection is common. While most children with recurrent infection have a normal immunity, it is important to recognize the child with an underlying primary immunodeficiency a...

Since recurrent bilateral breast infection due to nontuberculous mycobacterium (NTM) is rare, its diagnosis is easily overlooked; in addition, complete recovery is often difficult to achieve. We report a case of recurrent bilateral infection in a 35-year-old woman who had completed treatment for NTM. Although various infectious diseases show similar clinical conditions and imaging findings, rec...

The proportion of recurrent tuberculosis (TB) cases caused by re-infection has varied widely in previous studies. The aim of the present study was to determine the relative frequency of relapse and exogenous re-infection in patients with second episodes of TB, using DNA fingerprinting. A population-based retrospective longitudinal descriptive study was conducted in Madrid (Spain) during 1992-20...

BACKGROUND Biofilms are characteristic of some chronic or recurrent infections and this mode of growth tends to reduce treatment efficacy. Clostridium difficile infection (CDI) is associated with a high rate of recurrent symptomatic disease. The presence and behaviour of C. difficile within intestinal biofilms remains largely unexplored, but may factor in recurrent infection. METHODS A triple...

SUMMARY From April L 989 to March 1989 !here were 13 patients with small intestinal volvulus 23%, or all palients operated for small intestinal obstruction.All were male, age between 6 to 75, without any history of abdominal operation. Mortality was 38, 5% and morbidity included, intraabdominal abscesses, recurrent obstruction and wound infection were observed. Being the 3rd cause of intestin...
