Of 495 patients reported in a large urban histoplasmosis outbreak, we studied 276 whose serologic tests were done in a single laboratory. Serologic test results were positive in 96% of these patients (compared with less than 5% of controls from an endemic area), cultures were positive in 22%, and special stains in 19%. The immunodiffusion test results were(More)
An outbreak of histoplasmosis in Indianapolis involving 488 clinically recognized cases including 60 patients with disseminated or fatal infection permitted statistical analysis of risk factors. Being male, white, under 5 years of age, having chronic obstructive lung disease, and living near the presumed source of the outbreak were not risk factors for(More)
We have compared risk factors for cavitary histoplasmosis in 62 patients with that manifestation of the infection and in 679 patients with other forms of histoplasmosis, and we have evaluated the clinical and laboratory findings in 45 patients with cavitary histoplasmosis who were cared for at the Indiana University Medical Center hospitals during two large(More)
Human sera from Lodwar (77 sera), Nzoia (841 sera), Masinga (251 sera), Laisamis (174 sera) and the Malindi/Kilifi area (556 sera) in Kenya were tested by indirect immunofluorescence for antibodies against Marburg, Ebola (Zaire and Sudan strains), Congo haemorrhagic fever, Rift Valley fever and Lassa viruses. Antibodies against Ebola virus, particularly the(More)
Electrical impedance measurements can give useful information about the status of individual electrodes of a cochlear implant. Impedances within the normal range (when measured in the common ground mode of stimulation) suggest that current flow occurs in the tissue and fluid of the cochlea. Low impedance measurements may suggest that particular electrodes(More)
The microbiological counts were determined in an operating room suite of 8 rooms and a hallway. The bacterial counts in an empty operating room jumped statistically from 13 CFU/ft2/hr (+/- 31) to 24.8 (+/- 58.8) when the doors were left open (people in the hallways) and 447.3 (+/- 186.7) when 5 people were introduced. The wearing of a surgical face mask had(More)
A microbial evaluation was made of adhesive plastic surgical drapes and cloth surgical drapes. These studies were done both during surgery and in the laboratory. The plastic drape does not allow bacterial penetration, lateral migration does not occur, skin bacteria do not multiply under the drape within the time periods studied and the patient drapes are(More)
The concentration of the iron-binding protein lactoferrin was measured in vaginal mucus of women throughout the menstrual cycle. Lactoferrin is proposed to limit growth of mucosal pathogens such as Neisseria gonorrhoeae. Lactoferrin concentration in mucus was highest just after menses (62.9 to 218 micrograms/mg of protein) and lowest (3.8 to 11.4(More)
An outbreak of histoplasmosis estimated to involve more than 100,000 residents in Indianapolis, Indiana, occurred between September 1978 and August 1979. In the 435 cases evaluated, 52% of the patients were between 15 and 34 years old, and 63% were black. Fifteen patients died, and 46 progressive disseminated infection. Twenty-four patients had(More)
Studies were conducted on the sensitivity and specificity of indirect fluorescent-antibody (FA) staining for identification of group B coxsackieviruses. Antisera produced in four different species (monkeys, rabbits, horses, hamsters) and immune ascitic fluids prepared in mice were compared for suitability in FA staining. The horse antisera showed high(More)
