Crush syndrome of children in the Marmara Earthquake, Turkey

BACKGROUND

Crush syndrome is defined as traumatic rhabdomyolysis with systemic and local complications.

METHODS

Crush syndrome and its related complications were diagnosed on the basis of clinical and biochemical data. In this study, we evaluated 20 children with crush syndrome transferred to our center in Bursa during the Marmara earthquake, 1999. We investigated the clinical and laboratory findings of these children.

RESULTS

Serum creatine kinase, aspartate aminotransferase, and alanine aminotransferase levels were high in all patients. Fifty-five percent of the patients (n=11) had one extremity injury and 45% (n=9) had multiple extremity injuries. Fasciotomy was required in 15 children. Serum muscle enzymes and D-dimer levels were high in children with multiple extremity injuries. Acute renal failure developed in 35% (n: 7/20) of them. Peak serum creatine kinase level was positively correlated with aspartate aminotransferase, alanine aminotransferase, hospitalization time, serum urea and creatinine (P<0.05).

CONCLUSIONS

Crush syndrome was more severe in children with multiple extremity injuries and acute renal failure frequently developed in these children. Peak serum creatine kinase level as well as potassium, urea, uric acid, creatinine, lactic dehydrogenase, aspartate aminotransferase, alanine aminotransferase, and calcium levels were the helpful biochemical parameters in estimating the severity of crush syndrome.

Inferior vena cava indices determine volume load in minimal lesion nephrotic syndrome

The pathogenesis of edema in nephrotic syndrome has not been entirely understood. We investigated the value of the echographic parameters [inferior vena cava index (IVCI), inferior vena cava collapsibility index (IVCCI), and left atrium diameter (LAD)] to determine the volume load in children with minimal lesion nephrotic syndrome (MLNS). Twelve children with MLNS (seven boys, five girls) were included in this study. The patients were classified into three different stages (stage A: edematous; stage B: 50% decrease in weight gain; stage C: edema free) following measurement of their ideal weights. The ideal weight of patients in stage A was increased 13 +/- 7%. Serum total protein, albumin and urine sodium levels were found to be low in these patients. Plasma renin activity (PRA) and serum aldosterone levels in stage A were significantly different from those of the control group (P<0.05). PRA and serum aldosterone levels were not different from those of the control group in stage B (P>0.05). However, the increase in PRA was significant in stage C. Although a significant weight decrease was found in stages B and C, it had no effect on IVCI, LAD, and cardiothoracic index. We consider IVCI, IVCCI, and LAD measurements by echocardiography (ECHO) to be easy and reliable clinical methods for assessing the intravascular volume load in patients with MLNS.

Pseudoxanthoma elasticum: a rare cause of hypertension in children

We describe an 11-year-old girl with severe renin-dependent hypertension. She had characteristic cutaneous, ocular, and vascular signs of pseudoxanthoma elasticum (PXE), and the diagnosis was confirmed histologically. Because PXE is a heterogeneous heritable disorder, the family was evaluated for this condition. Since the patient's mother and brother showed some manifestations of PXE, autosomal dominant inheritance is the most likely inheritance pattern in this family.
