Delayed diagnosis of breast cancer as a result of normal mammograms.

Review of the effects of a normal mammogram on the treatment of 36 women with palpable breast carcinomas during a two-year period showed that 17 patients had biopsies performed within two months of their normal mammograms and 19 patients had biopsies delayed for three to 24 months. Of the 17 who had biopsies within one month of a normal mammogram, three (17.6%) had extension of disease to axillary nodes. Of 19 patients whose biopsy was delayed, cancer was found in axillary nodes of 11 (57.9%). Normal mammograms should not preclude biopsy of a breast mass.

[Collagen disease with pure red cell anemia and perimembraneous glomerulonephritis (author's transl)].

Record on a case of collagen disease with pure red cell anemia and perimembraneous glomerulonephritis. The direct antiglobulin tests with anti-IgG and anti-kappaserum were positive as were the tests on antinuclear serum-antibodies. During therapy with fluocortolon and azathioprin the anemia remitted completely even when therapy was stopped. The antiglobulin tests became negative, the glomerulitis remained active, there was no deterioration of renal function.

[Perimembranous glomerulonephritis after treatment with D-penicillamine. Report on 31 cases (author's transl)].

This report includes 31 patients who developed a perimembranous glomerulonephritis generally 7 months after the onset of the treatment of various illnesses with D-Penicillamine. In all cases the patients had a proteinuria, associated with a hematuria in 12 cases. After the treatment was stopped 8 patients rapidly developed a nephrotic syndrome, while its onset was more gradual in 12 other patients. 5 patients initially with a nephrotic syndrome had no proteinuria at the time of a second biopsy made up to 12 months later. In these 5 cases the typical changes of perimembranous glomerulonephritis observed on electron microscopy were much reduced in the second biopsy.

Semiautomated turbidimetric microbiological assay for determination of cefazolin.

The Autoturb System, a semiautomated system for photometric bioassay, was used to determine cefazolin content. Suitable conditions for the assay using Streptococcus faecalis ATCC 10541 as the indicator organism included a medium pH of 6.0 to 7.0 and an incubation time of 3 to 3.5 h at 36 C. Multiple independent assays of samples from a common batch showed the test to be highly reproducible. Accuracy of the turbidimetric assay was evaluated by comparing data obtained from a chemical (hydroxylamine) and a biological (disk diffusion) assay. The available data show the turbidimetric assay to be a rapid, accurate, and reproducible method for determining the biological activity of cefazolin samples.
