[EX Q]: Abstract: Three myopic patients who wore soft contact lenses developed unilateral Acanthamoeba keratitis that presented with unusual infiltrates that appeared to be located along the corneal nerves. These infiltrates were found in the midstroma, beginning paracentrally, and extending to the limbus in a radial pattern. The epithelium overlying these infiltrates was intact. In two patients, the central epithelium had a stippled, almost dendritiform appearance leading to the misdiagnosis of herpes simplex keratitis. Cultures from corneal scrapings of two patients and cultures of a corneal biopsy from one patient, which included an area of presumed neural involvement, grew Acanthamoebae. All three patients used homemade saline solutions (salt tablets dissolved in distilled water). In one patient, Acanthamoebae were found in the contact lens case solution. In our recent experience, Acanthamoebae have also been found in the distilled water bottle and the saline solution made from distilled water and salt tablets in two additional patients with A. keratitis. Distilled water, which is not sterile, has proven to be one potentially avoidable source of A. keratitis in contact lens wearers.

[EX Q]: Abstract: We report a case of a small infant apparently dying of the Sudden Infant Death Syndrome (SIDS) with a postmortem blood dicyclomine level of 200 ng/mL. Review of the literature and the comparison with blood dicyclomine values from four rabbits given equivalent doses suggests that a blood dicyclomine value of 200 ng/mL probably is in the therapeutic range for infants. Although safely used for years for infantile colic, recently, the administration of dicyclomine has been related to acute episodes of apnea, seizures, and coma. In the absence of those acute reactions, we feel that a 200-ng/mL blood dicyclomine level in a child dying of apparent SIDS should not prevent categorization of the death as SIDS.

[EX Q]: Abstract: The apolipoprotein B-100 (apoB-100) gene in leukocytes and the apoB-100 messenger RNA (mRNA) and translated apolipoprotein in the livers from normal and abetalipoproteinemic individuals were evaluated. Four complementary DNA probes for apoB-100 covering the 5', middle, and 3' regions of the apoB-100 mRNA were utilized and Southern blot analysis indicated that the apoB-100 gene is present in abetalipoproteinemia without major insertions or deletions. Polyadenylated hepatic apoB-100 mRNA from two abetalipoproteinemic patients was normal in size, and the concentration of apoB-100 mRNA was increased sixfold compared with control hepatic apoB-100 mRNA levels. ApoB-100 was detected in hepatocytes of abetalipoproteinemic patients by immunohistochemical techniques. These results indicate that the biochemical defect in abetalipoproteinemic patients studied is most consistent with a posttranslational defect in apoB-100 processing or secretion with an up-regulation of the apoB-100 mRNA.
