    Childhood idiopathic nephrotic syndrome in Turkey
    (Blackwell Publishing Asia, 2002) Bircan, Z; Yilmaz, AY; Katar, S; Vitrinel, A; Yildirim, M
    Background : It has been reported that there are racial and regional differences in peak incidence age, histopathological features and response to steroid therapy in childhood idiopathic nephrotic syndrome. Methods : One hundred and thirty-eight patients with a diagnosis of idiopathic nephrotic syndrome, followed up in 1994-2000, were assessed retrospectively. The aim of this study was to assess the patients response pattern to steroid therapy, to determine whether the duration of the initial steroid therapy alters the steroid response pattern of the disease and to assess renal biopsy results. Results : One hundred and fourteen patients who initially received only steroid therapy and were followed up regularly were classified according to response pattern. Of the 114 patients, 30 children had an initial response, 25 children had infrequent relapse, 19 had frequent relapse, 25 had steroid dependence and 15 children had steroid resistance. The 99 patients with steroid responsive nephrotic syndrome were divided into two groups with respect to duration of the initial steroid therapy. There was no statistically significant difference between standard and short therapy groups with respect to the steroid response patterns. Percutaneous renal biopsy was performed in 43 of the 138 patients. Mesengioproliferative glomerulonephritis was the most common histopathological lesion, followed by membranoproliferative glomerulonephritis. The proportions of membranous glomerulonephritis, focal segmental glomerulosclerosis and minimal change nephrotic syndrome were low in our group. Conclusions : Our study group is similar to one reported from Saudi Arabia with respect to the steroid response pattern and to Saudi Arabian and Nigerian reports with respect to the histopathology. Although it has been reported that short initial steroid therapy was followed by a higher rate of relapses, there was no statistically significant difference between standard and short therapy groups with respect to the relapse rate in our study group.

    Does albumin and furosemide therapy affect plasma volume in nephrotic children?
    (Springer, 2001) Bircan, Z; Kervancioglu, M; Katar, S; Vitrinel, A
    Albumin infusions transiently increase plasma volume (PV) and oncotic pressure, and may restore diuretic responsiveness in nephrotic edema. To determine if albumin and furosemide therapy have an effect on PV in nephrotic children, 14 severely edematous children with minimal change nephrotic syndrome were evaluated with standard clinical parameters (heart rate, blood pressure, body weight, pretibial edema, abdominal circumference) and echocardiography [inferior vena cava index (IVCI), inferior vena cava collapsibility index (IVCCI)] before, 1 h and 24 h after albumin (20%, 0.5 g/kg, 1 h) and furosemide (2 mg/kg, IV) therapy. An increase in IVCI (P <0.05), decrease in IVCCI (P<0.05), edema (P0.005), and hematocrit (P <0.005) were statistically significant 1 h after albumin and furosemide therapy, with a transient effect 24 h later. Body weight (P <0.005), abdominal circumference (P <0.05), and edema (P <0.005) decreased significantly at 24 h. It is concluded that albumin and furosemide therapy increases PV transiently in nephrotic edema, returning to baseline values at 24 h with a decrease in body weight, abdominal circumference, and edema.

    Henna-induced hemolytic anemia and acute renal failure
    (Turkish J Pediatrics, 2001) Devecioglu, C; Katar, S; Dogru, Ö; Tas, MA
    Henna is a traditional cosmetic agent ana is used worldwide, especially in the Middle East. Its active agent is lawsone (2-hydroxy-1,4-naphthoquinone). Henna is not only applied to hands or hair as a cosmetic agent in traditional ceremonies, but is also applied to the body on lesions in the treatment of seborrheic dermatitis or fungal infections. However, its application over the body or in newborns is rare. Here we report a 27-day-old boy who developed hemolytic anemia and acute renal failure following topical application of henna to his abdomen, intertriginous region and legs to treat diaper rash.
