Hypokalemia and hyperkalemia are the most commonly encountered electrolyte abnormalities in hospitalized patients. Because untreated hypokalemia or hyperkalemia is associated with high morbidity and mortality, it is important to recognize and treat them immediately. Hypokalemia and hyperkalemia can result from disruptions in transcellular homeostasis or in the renal regulation of K＋ excretion. Although the recognition is simple, appropriate management requires...

The Value of Serum Concentration of Cystatin C as a Marker for Glomerular Filtration Rate in Children and Adolescents
Young-Su Jung, In-Seok Lim
Clin Exp Pediatr. 2005;48(6):614-618.   Published online June 15, 2005
Purpose : Cystatin C has been proposed for the assessment of glomerular filtration rate, being more accurate than creatinine determination. We measured serum cystatin C concentrations in the pediatric population, and analysed the correlation between cystatin C and glomerular filtration rate. Methods : Cystatin C and creatinine were measured by the particle enhanced nephelometric immunoassay and Jaff method, respectively, in...

Bronchogenic cysts are rare congenital anomalies that arise early in gestation from abnormal budding of the developing respiratory system. Mediastinal bronchogenic cysts account for 10-15 percent of all primary mediastinal masses; 63.7 percent of patients are symptomatic. Common symptoms are fever, chest pain, cough, dyspnea, and dysphagia. Gastrointestinal symptoms except dysphagia are rare. It can be life threatening with compression,...
