Progressive massive fibrosis in a zinc miner.

The diagnosis of progressive massive fibrosis (PMF) is traditionally associated with exposure to coal dust. Since the legislation of better control of mine dust, the incidence of PMF has declined significantly. Clinicians who are not regularly involved in the medical care of coal workers may have limited knowledge of this incapacitating problem. Physicians are reminded that PMF is a complex process that can occur after exposure to mixed respirable particles other than coal dust.

Susceptibility to rubella infection in females at high risk. Immune protection associated to population density.

Susceptibility to rubella in 428 Mexican females of childbearing age from four sanitary areas confined to a Mexican State (Queretaro) was determined. Members of the group were residents of urban and rural communities and selected by random sampling. Anti-viral antibodies were determined by inhibition of haemagglutination. Concentration was expressed as International Units of IgG anti-rubella haemagglutinin (IU/ml). Antibody concentrations lower than 15.6 (IU/ml) were regarded as non-protective. The percentage of women immune-protected to rubella in the areas varied from 28.8 to 75.6 with an average of 61.9. The difference in percentages of immune-protected females within the areas was statistically significant (chi 2 = 48.26 and p < 0.001). Immune protection was associated to population density, with less protection in less populated areas. Our results differ from the reported values of a serosurvey performed in the same state one year before: immune protection 61.9% versus 79.96%, respectively.

Correlation of serum fructosamine activity in type I diabetic children.

The serum fructosamine assay is a new commercially available test designed to measure serum glycated protein as an index of glycemic control in diabetes. The test relies on the ability of glucose bound to protein with a ketamine linkage (fructosamine) to act as a reducing agent in alkaline solution. Serum fructosamine activity was studied in 61 Type I diabetic patients attending a 2-week American Diabetes Association sponsored diabetic camp for children. The initial fructosamine level was found to correlate well with the initial HgA1C value (r = .82, p less than .001). To assess if mean blood glucose correlated with these objective parameters, the authors performed capillary blood glucoses preprandially and at bedtime on all 61 diabetic campers during the 2-week period of observation and reassessed serum fructosamine activity and HgA1C on day 14 of camp. We found the HgA1C and fructosamine correlated well with the mean daily blood glucose obtained during the preceding week (r = .45, p less than .01 and r = .58, p less than .01) respectively. Our data suggest that the serum fructosamine is as effective as the HgA1C in correlating to mean blood glucose control in this cross-sectional study of Type I diabetic patients.
