Pulmonary blastomycosis - A great masquerader
- [Show abstract] [Hide abstract]
ABSTRACT: A chronically implantable neural information transducer is being developed for physiological and clinical applications. The technology is based on microfabricated silicon structures which can eventually integrate signal processing circuitry on the same substrate. The micromachined probe structure has been optimized for biocompatibility. Fabrication and design aspects of the probe which determine the ultimate signal to noise ratio of the system have been identified and are being optimized. A sensor and analytical technique for non-destructive assessment of thin film passivation layers has been identified and will be used to develop passivation technology for chronically implantable neural information sensors.Electron Devices Meeting, 1986 International; 02/1986

ABSTRACT: Clinically, blastomycosis can be difficult to recognize even in the endemic areas where clinicians are aware of this problem. In only 18% of 123 patients from the University of Mississippi Medical Center (Jackson, MS) blastomycosis was correctly suspected at the initial patient evaluation. Pneumonia sensu latu (40%), malignant tumors (16%), and tuberculosis (14%) were the most common misdiagnoses. The false first impression frequently resulted in unnecessary surgeries or treatment delays, with patients receiving inefficient antibiotic therapy for months. The presence of cutaneous involvement by the disease makes its' recognition easier for the clinician, raising the percentage of correct initial diagnosis to 64%. To evaluate the association with immunodepression, the presence of other diseases was also searched among the 123 patients. An immunodepressive condition preceded the fungal disease in 25% of patients. Another associated disease commonly found in blastomycotic patients was diabetes mellitus (22%). Blastomycosis is correctly suspected at the first clinical evaluation in only a small percentage of patients; pneumonia, cancer, and tuberculosis are the most common clinical considerations. Cutaneous involvement leads the clinician to the correct diagnosis in the majority of cases. One fourth of the patients with blastomycosis had underlying immunodepressive conditions, and underlying diabetes mellitus is present in 22% of patients.Annals of Diagnostic Pathology 07/2002; 6(3):194-203.

Article: Blastomycosis and Pregnancy[Show abstract] [Hide abstract]
ABSTRACT: Blastomycosis is an exceedingly uncommon complication of pregnancy, rarely encountered by the practicing obstetrician. However, recognizing its presence during pregnancy and expeditiously initiating appropriate therapy is of critical importance to the mother and fetus. Mississippi has the highest prevalence of blastomycosis in North America. Nevertheless, there have been only three pregnancies complicated by this fungal disease at the University of Mississippi Medical Center (Jackson, MS) during two decades. During the same time frame there were another 120 blastomycotic patients treated at the University of Mississippi Medical Center. As a condition of partial immunodepression, a nonobligatory opportunistic fungal disease like blastomycosis can complicate pregnancy. From data on our three patients and 16 other published cases, it seems that fetal risk exceeds maternal risk. There were a total of 20 babies born from mothers with blastomycosis. Only two babies (10%) had transplacental infection and both succumbed to blastomycosis. None of the 18 affected mothers for whom data was available died of the disease. Furthermore, there was never progression in the mothers, with 14 complete cures and considerable postpartum regressions of lesions in the other four women. Even the three women who received no treatment had either noticeable improvement or total regression of the disease after delivery. One of the two stillborns with blastomycosis was born to an untreated mother.Annals of Diagnostic Pathology 09/2002; 6(4):211-5. DOI:10.1053/adpa.2002.34729 · 1.11 Impact Factor
