Most of the patients already had difficult-to-diagnose intestinal trouble, which was one reason why they were in Boston's famed Massachusetts General Hospital in the first place. Many of them were children. But unaccountably, when doctors gave them tests, some of the patients developed worse diarrhea...
Detection of any kind of highly infectious Salmonella* anywhere in the U.S.-particularly in a hospital-is enough to set disease detectives working overtime. Salmonellosis is a particularly severe diarrhea, often accompanied by vomiting, acute cramps and fever; and it can be fatal to feeble youngsters and oldsters. In the Boston case, it fell to Pediatrician David J. Lang to find out whatdunit. From case records, Dr. Lang concluded that while some of the children had been infected with S. cubana when they entered the hospital, others had picked up the infection there. That made the job tougher. Dr. Lang...
Contagious Cuddling. The germs in question comprise the bacteria Shigella and Salmonella along with Escherichia coli, a common cause of infant diarrhea. Since these organisms reproduce slowly by cell division, microbiologists used to think that it would take a long time for drug-resistant strains to multiply and populate a hospital. Not so, indicates recent research. In addition to cell divi sion, these bacteria have a second way of passing on their "R factor" (drug resistance). When they cuddle up close to other bacteria, the R factor is transmitted by means of DNA (deoxyribonucleic acid), which bears chemical instructions...
...effects of severe lactase deficiency can be both distressing and dramatic. After drinking a glass of milk, the victim soon doubles up with cramps that may spread across his entire distended abdomen. He suffers nausea and flatulence, and then a profuse, watery diarrhea. The mechanism of these reactions has now become clear, say Dr. Struthers and his Colorado colleague, Dr. Fred Kern Jr. Lactase is supposed to do its sugar-splitting work along the lining of the small bowel; if the enzyme is missing or in short supply, the undigested sugar passes into the large bowel, where it is promptly...
...research in lactase function are being drawn to doctors' attention for use in their daily practice, the A.M.A. Journal has been moved to rhapsodize editorially: "What a joy to the clinician to find the arcane skills of research scientists directed to such matters as bloating, flatulence, cramps and diarrhea!" The Journal adds: "Some patients will now acquire a new dignity, with the status of enzyme deficiency rather than neurosis...
