JAMA -- Abstract: A large food-borne outbreak of hepatitis A. Possible transmission via oropharyngeal secretions, October 20, 1975, Levy et al. 234 (3): 289 (#)
„In Minneapolis, 107 cases of hepatitis A were identified and traced primarily to consumption of cold sandwiches served for lunch in a department store's popular basement restaurant. A sandwich-maker in the restaurant was the index patient. The date of onset of her illness and the dates of food consumption and onset of illness of infrequent restaurant patrons were consistent with accepted periods of infectivity and incubation for hepatitis A. Because the sandwich-maker frequently touched her hands to her mouth when she worked, and because we could not find evidence for fecal, airborne, or other modes of transmission, we believe that she may have contaminated food with infectious oropharyngeal secretions.“

„During intravenous and after intramuscular penicillin therapy, a spinal tap was performed on all subjects; later, assays were done. Of two patients who received intravenous penicillin G, one had 0.3 mug/ml and the other had 2.4 mug/ml penicillin in the CSF. Twelve of 13 patients who received benzathine penicillin G had no detectable penicillin in the CSF; one patient had 0.1 mug/ml penicillin in the CSF.“

„Little information is known regarding caffeine's effect on the substrate supporting sustained ventricular arrhythmias. This prospective study evaluated the effect of coffee (275 mg of caffeine) on this substrate with programmed ventricular stimulation in 22 patients with a history of symptomatic nonsustained ventricular tachycardia, ventricular tachycardia, or ventricular fibrillation. Patients underwent electrophysiological testing before and 1 hour after coffee ingestion. Mean (+/- SEM) plasma caffeine level achieved after coffee consumption was 6.2 +/- 0.5 mg/L.“

„Criteria used for making diagnoses (and rates of their prevalence) were as follows: withdrawal (94%), use continued despite knowledge of a persistent or recurrent physical or psychological problem that is likely to have been caused or exacerbated by caffeine use (94%), persistent desire or unsuccessful efforts to cut down or control use (81%), and tolerance (75%). Eleven subjects underwent the double-blind caffeine-withdrawal evaluation portion of the study, and nine (82%) of the 11 showed objective evidence of caffeine withdrawal, including eight of 11 with functional impairment. CONCLUSIONS--These results, together with other experimental evidence, suggest that caffeine exhibits the features of a typical psychoactive substance of dependence. It is valuable to recognize caffeine dependence as a clinical syndrome, since some people feel compelled to continue caffeine use despite desires and recommendations to the contrary.“
