31 cases of non-fulminant hepatitis A complicated by acute renal insufficiency are reported in the literature. Two-thirds of those patients needed dialysis, usually when depending on the severity of their hyperbilirubinemia. This report concerns the first published case of non-fulminant cholestatic hepatitis A complicated by acute renal insufficiency in which a spontaneous remission of renal function occurred without need for dialysis despite a very severe hyperbilirubinemia.

Abstract A screening test for increased concentrations of lysozyme (muramidase) in the urine is described.

A patient with a penile lesion belonging both grossly and microscopically to the disease commonly known as "sclerosing lipogranuloma of the genital organs" confessed that at one time he had injected a suspension of pumice subcutaneously into his penis. This remarkable story was verified when a biopsy of the "lipogranuloma" proved to contain large amounts of rhombic crystals consisting of bundles of crystalline rods strongly birefringent in polarized light and closely resembling the crystal structure of pumice. In view of this finding it seems advisable to replace the term "sclerosing lipogranuloma of the genital organs" by the designation "factitious genital sclerogranuloma." The patient suffered also from familial symmetrical lipomatosis. In our opinion the coexistence of these two diseases is fortuitous.
