Salmonella infection is a common bacterial disease that affects the intestinal tract. Salmonella bacteria typically live in the intestines of animals and humans and are shed through feces. Humans become infected most frequently through contaminated water or food sources — such as poultry, meat and eggs.
Typically, people with salmonella infection develop diarrhea, fever and abdominal [...]

Antibiotic-associated diarrhea can cause signs and symptoms that range from mild to severe. Most often, you’ll have only a slight change in the bacteria in your digestive tract, which can cause loose stools or more bowel movements a day than are normal for you.

Hydronephrosis [water - kidney condition] refers to a kidney with a dilated pelvis and collecting system. It can be caused by obstruction of the ureters or bladder outlet. Hydronephrosis can also result from reflux (retrograde leakage of urine from the bladder up the ureters to the renal pelvis. Rarely, some children have hydronephrosis without either [...]

In the past decade, the single most common cause of the withdrawal or restriction of the use of drugs that have already been marketed has been the prolongation of the QT interval associated with polymorphic ventricular tachycardia, or torsade de pointes (Figure 1), which can be fatal.1 Nine structurally unrelated drugs that were marketed in [...]

Uremia describes the final stage of progressive renal insufficiency and the resultant multiorgan failure. It results from accumulating metabolites of proteins and amino acids and concomitant failure of renal catabolic, metabolic, and endocrinologic processes. No single metabolite has been identified as the sole cause of uremia. Uremic encephalopathy (UE) is one of many manifestations of [...]

Objective: To define the true incidence and nature of acidosis
in pediatric patients postcardiac surgery, using Stewart’s direct
method of measuring strong ion difference. We also wished to
compare the ability of standard indirect methods (base deficit,
lactate, anion gap, and corrected anion gap) to accurately predict
tissue acidosis.
Design: A single-center prospective observational study.
Setting: A pediatric intensive care unit in [...]
