Coccidioides immitis meningitis with arthroconidia in cerebrospinal fluid: report of the first case and review of the arthroconidia literature.

The authors report the first case in which the spherules and arthroconidia of Coccidioides immitis were identified from an indwelling cerebrospinal fluid reservoir. The organism was recovered in culture. Present as isolated meningitis, the patient's infection disseminated over a 12-year period despite intrathecal and intravenous administration of amphotericin B. The unusual findings in this patient are compared with findings in 95 cases of infections containing arthroconidia reported since 1940. Arthroconidia is most likely to be found in the tissues of white male patients who are in the third or fourth decade of life and have pulmonary lesions.

Helminthosporium corneal ulcers.

Two cases of fungal corneal ulcer caused by Helminthosporium are discussed. Dematiacious fungi are pigmented filamentary molds of which Helminthosporium is representative. Ulcers due to such dematiacious fungi seem to have a better prognosis than other types of fungal corneal ulcers. The importance of classifying fungal ulcers is emphasized. Therapy is considered for these keratomycoses.

Improved transport incubator temperature control with insulating thermal cover.

INTRODUCTION: Cold stress, secondary to heat loss, can compromise infants in transport incubators during interfacility transfer. With current incubator designs, considerable radiant heat loss occurs. The use of additional external thermal insulation to reduce heat loss has been recommended for infant transports in cold environments. METHOD: A laboratory experiment was done to compare the rate of heat loss from a transport incubator with and without a commercially available, thermal insulating cover in place. The environment was a commercial freezer simulating subzero environmental temperatures. Measurements included air temperatures. inside the incubator and freezer, patterns of heater action and duration of battery power output. The significance of the different rates of cooling was compared using Pearson's r. Suboptimal battery performance was excluded by repeating one arm of the study with an external battery in place of the internal unit. RESULTS: The rate of heat loss from the incubator was: 1) significantly slower when the covered and uncovered incubators were compared (r2 = 0.52), and 2) essentially identical for the uncovered incubator with either the internal or the external battery (r2 = 0.96). CONCLUSION: In the laboratory setting, external thermal insulation slows transport incubator radiant heat loss. Clinically, this effect likely would benefit infants at risk of cold stress during interfacility transports.
