Metabolic acidosis due to d-lactate in a patient with intestinal resection: Diagnostic challenges and nutritional strategies.

Introduction: Metabolic acidosis, marked by decreased plasma bicarbonate and arterial pH, is a common complication following extensive abdominal surgeries. D-lactate acidosis presents additional diagnostic challenges due to nonspecific symptoms.

Presentation Of Case: A 65-year-old woman with hypertension and morbid obesity was admitted to the ICU for intestinal obstruction and peritonitis due to an incarcerated hernia.

Effect of a standardized approach on infants hospitalized for apparent life threatening events.

Introduction: An apparent life-threatening event (ALTE) is a frequent cause of hospitalization in infants. However, there is little evidence about the existence of a standardized approach to discover the main etiology, although a correct causal diagnosis can affect clinical evolution, hospital stay, and health resources. Objective: To determine the effects of a standardized diagnostic approach in infants admitted with ALTE.

Exercise challenge test: is a 15% fall in FEV(1) sufficient for diagnosis?

Introduction: In the exercise challenge test (ECT), a drop in forced expiratory volume in the first second (FEV(1)) of between 10 and 15% is the determinant variable for a diagnosis of exercise-induced bronchospasm.

Hypothesis: The use of FEV(1) plus mean forced expiratory flow between 25% and 75% of the forced vital capacity (FEF(25-75%)) may increase the sensitivity of the ECT in asthmatic children.

Specific Objective: To compare FEV(1) and FEF(25-75%) changes in a group of asthmatic and healthy children.
