Richner Hanhart syndrome is a rare inherited disorder involving the metabolism of tyrosine, a semi-essential amino acid and it should be considered in the differential diagnosis of a child presenting with ocular and skin lesions. We report a case of Richner Hanhart syndrome in a 19-month-old child, who presented with ocular and skin lesions.
A study was undertaken to analyze the usefulness of radiographic and ultrasonographic findings and area specific hematocrit cut off values in Dengue Hemorrhagic Fever (DHF). Of the 65 cases, 35 were DHF and 30 were Dengue Fever as per the WHO case definition. Among the DHF cases, hemoconcentration (>20%) was detected in 20 cases (57.14%), hypoproteinemia in 11 (31.42%) and clinical evidence of pleural effusion and or ascites in 25 (71.42%). Hemoconcentration based on area specific hematocrit cut off values was observed in 32 cases (91.42%). Ultrasonographic evidence of plasma leakage was seen in 32 cases (91.42%). In detecting plasma leakage, area specific hematocrit cut off values and ultrasonography had the highest sensitivity (91.42%), while ultrasonography had the highest negative predictive value of 84.21%. Clinical evidence of plasma leakage was more frequent than hemoconcentration or hypoproteinuria. Ultrasonography is an ideal non-invasive investigation to detect plasma leakage and area specific hematocrit values are useful as evidence of plasma leakage.
Bartter syndrome is an inherited renal tubular disorder with hypokalemia, hypochloremic metabolic alkalosis, normal blood pressure with hyper-reninemia and increased urinary loss of sodium, potassium and chloride. We report an infant with neonatal Bartter syndrome, who improved with potassium supplements.
Every 5 years the American Heart Association (AHA) updates the Guidelines for CPR and Emergency Cardiovascular Care (ECC). The ECC Guidelines 2000 incorporates all the current consensus of experts, from not only a variety of disciplines, but also a variety of countries and cultures and is evidence based. The new Guidelines emphasize interventions to reduce the risk of sudden deaths, early identification of respiratory failure and shock and implementation of Advanced Life Support (ALS) to treat respiratory and cardiac arrest.
