shigellosis is an important public health problem, especially in developing countries. antibiotic treatment of bacterial dysentery, aimed at resolving diarrhea or reducing its duration is especially indicated whenever malnutrition is present. first-line drugs include ampicillin and trimethoprim sulfamethoxazole(tmp-smx); however multidrug-resistance has occurred and careful antibiotic selection...

The clinical and laboratory findings of 290 cases of bloody diarrhea who presented to the department of Diarrhea Training and Treatment between June 1998 and May 2002 were investigated, and compared to those of two consecutive cases who had watery diarrhea. The bloody diarrhea group had higher mean age, higher frequencies of diarrhea, lower frequencies of vomiting, and shorter durations of diar...

Seven of the nine people present at the barbeque developed diarrhea with abdominal cramps between 3 to 10 days following the barbeque (Fig.1). Two had bloody diarrhea. The two children with bloody diarrhea (an 11-month-old male and a 15-year-old female) and one with non-bloody diarrhea (a 4-year-old female) sought medical attention. There was sufficient stool from two of these children (the 11-...

While the patient was diagnosed with norovirus gastroenteritis based on the presence by chance of positive norovirus antigen in the stool samples, endoscopic as well as pathological examinations demonstrated left-sided ischemic colitis.

An accurate diagnosis remains the foundation for a succ...

We present an analysis of strain and patient factors associated with the development of bloody diarrhea and hemolytic uremic syndrome (HUS) among Shiga toxin-producing Escherichia coli (STEC) patients registered in Denmark in a 6-year period. Of 343 STEC patients, bloody diarrhea developed in 36.4% and HUS in 6.1%. In a multivariate logistic regression model, risk factors for bloody diarrhea we...

18.9) and also weakly associated with development of bloody diarrhea (OR = 2.5) (2). Avery uses the term endogeneity as it is used in econometric analyses; however, the term “intermediary variable,” i.e., a factor in the causal pathway leading from exposure to disease, is more frequently used in epidemiology. In this context, we chose to consider bloody diarrhea as a potential confounder (3). A...
