Postoperative femoral neuropathy.

Postoperative femoral neuropathy is more common than it is generally appreciated. It can occur by a number of different mechanisms after a wide variety of operations as a result of either direct or indirect injury. Most instances occur after abdominopelvic operations and are associated with the placement of self-retaining retractors.

Acute renal failure and non-Hodgkins lymphoma in a patient with minimal change glomerulonephritis.

Two rare features of minimal change glomerulonephritis occurring together in an adult patient are described. A 70-year-old man presented with acute renal failure and the nephrotic syndrome. Investigation revealed minimal change glomerulonephritis and non-Hodgkins lymphoma.

Transitional cell carcinoma of upper urinary tract: some prognostic indicators.

Thirty cases of transitional cell carcinoma were reviewed over a twenty-year period. The incidence of bladder tumor recurrence was no different in those who had complete or incomplete nephroureterectomy. Grade and stage correlated well with survival.

Aluminium encephalopathy: clinical and immunological features.

Aluminium encephalopathy is a specific syndrome occurring in dialysis patients and linked to high aluminium levels in dialysis water. We present the features of 38 cases seen in a single dialysis and transplantation unit. Serum immunoglobulin levels and the prevalence of histocompatibility antigens are discussed.

Systemic lupus erythematosus: Renal involvement and prognosis.

In 20 cases of systemic lupus erythematosus the renal biopsy findings permitted morphological classification with features of prognostic value. Glomerulosclerosis and interstitial fibrosis correlated best with the clinical course. Renal involvement, with a 90% 5 year survival, may have less sinister implications for this population, in contrast with the poor prognosis reported in comparable series.

IgA nephropathy-An immunopathological study.

IgA nephropathy is described in 11 cases out of a total of 177 renal biopsies examined representing an incidence of 6.2 per cent.Reference is made to comparable studies from other centres.

The Periodic Schiff-Methenamine (PASM) staining of renal biopsies-A light and electron microscopic study.

Methods for Periodic Schiff-Methenamine Silver (PASM) staining of human kidney glomerular basement membranes in epoxy resin-embedded one μm thick sections were investigated. Removal of the resin prior to staining gave better resolution of cytological detail than sections which were still embedded in the resin. Various methods for the fixation of renal biopsies were compared; osmium tetroxide fixation produced the best visual differentiation of the glomerular basement membrane as a distinct entity from the deposits adjacent to it.
