Type IV renal tubular acidosis(RTA) is due to renal tubular bicarbonate wasting associated with mineralocorticoid deficiency. In its five subtypes, IV-4 is due to pseudohypoaldosteronism(PHA) evidenced by increased plasma renin and aldosterone. PHA is believed to result from distal tubular unresponsiveness to circulating aldosterone and has normal renal and adrenal fuction. Hypoaldosteronism can easily be suspected when the patient shows typical electrolyte imbalance (hyponatremia coupled with...

The development of respiratory management of the newborn has improved the survival rates of respiratory distress syndrome in these two decades. But the incidence of complication associated with this management has been increased. Although the pathogenesis of bronchopulmonary dysplasia has not been clearly established yet, bronchopulmonary dysplasia is one of the major complication of the mechanical ventilation. There are several factors in the development of...
