Changing patterns in the histopathology of idiopathic nephrotic syndrome in children.

BACKGROUND: It is widely accepted that minimal change nephrotic syndrome (MCNS) is the most common cause of nephrosis in children. Recent studies have demonstrated an increasing incidence of focal segmental glomerulosclerosis (FSGS) in adults. METHODS: To determine possible changes in the etiology of childhood nephrosis, the clinical charts of 152 pediatric patients diagnosed with idiopathic nephrotic syndrome between 1978 and 1997 were reviewed. Histopathological diagnosis was available in 105 patients. RESULTS: MCNS was present in 35% of all biopsies, whereas FSGS was observed in 31%. Even if we assume that all patients without a histological diagnosis had MCNS (presumptive MCNS), the total incidence of MCNS (biopsy proven + presumptive) in our population was only 55%. We observed a dramatic increase in the incidence of FSGS during recent years. Before 1990, FSGS was diagnosed in 23% of all renal biopsies but increased to 47% afterward (P = 0.02). This pattern was observed in all ethnic groups. In African Americans, there was a trend for an increase in the incidence of FSGS from 38% before 1990 to 69% after 1990. A similar trend was observed in Caucasians (from 20 to 45%) and Hispanics (from 8 to 33%) Hispanics had the highest incidence of MCNS (biopsy proven + presumptive: 73%), followed by Caucasians (53%) and African Americans (37%). The mean age for presentation of nephrotic syndrome in African Americans (8.0 +/- 0.9 years) was higher than in Caucasians (4.1 +/- 0.05) and Hispanics (3.3 +/- 0.5). CONCLUSIONS: Our study showed that the incidence of FSGS in children with idiopathic nephrotic syndrome has increased recently. Furthermore, in African American children. FSGS is the most common cause of nephrotic syndrome. These findings may have significant implications in the management of childhood nephrotic syndrome.

Dietary polyunsaturated fats and malignant melanoma.

The consumption of polyunsaturated fat of a group of patients with malignant melanoma was compared to that of various groups of control subjects to determine whether such dietary fats predispose to the development of malignant melanoma. The results are tabulated with reference to various associated factors, and a statistical assessment of their significance is presented. The writers were unable to agree on the interpretation of the results, and present two opposing views on whether the ingestion of polyunsaturated fat is associated with the incidence of malignant melanoma.

Response of leukocytes in chickens infected with the avian schistosome Austrobilharzia variglandis (Trematoda).

Leukocyte levels were monitored weekly in chickens infected with the avian schistosome Austrobilharzia variglandis. Changes in relative and absolute numbers of leukocytes were recorded over a 7-week period beginning 1 week before exposure. There was a significant increase (P less than 0.001) in total leukocytes, peaking at 5.8 X 10(4) cells/mm3 on day 21 postexposure; controls had 2.4 X 10(4) cells/mm3 on that day. The leukocyte count declined over the next 3 weeks, returning to nearly normal levels by day 42 postexposure. With the exception of eosinophils, which peaked 35 days postexposure, all leukocyte subpopulations peaked in number on day 21. Increases in heterophils and monocytes were related to the schistosome egg burden.

A new method for the identification and enumeration of chicken heterophils and eosinophils.

A method for the direct counting of chicken heterophils and eosinophils using Phloxine B stain and a hemacytometer is described. A solution of 0.1% Phloxine B in 50% propylene glycol stained heterophils and eosinophils obtained from peripheral blood. The cytoplasm of heterophils became completely stained, whereas that of the eosinophils stained incompletely, thereby enabling these cells to be distinguished easily from each other. Identification of cell type was confirmed by comparing cell counts prepared from blood smears stained with Wright's stain with wet mounts (hemacytometer preparations) stained with Phloxine B.
