Gastroentological investigations.

In this fourth article in the Concepts in Anatomy series, Anne-Marie Ramsay joins John Clancy and Andrew McVicar in examining the upper and lower gastrointestinal tract and identifies some common homeostatic imbalances. Diagnostic tests for detecting abnormalities are described, highlighting the importance of the nurse's role in caring for the patient throughout these procedures. This series is based on Physiology and Anatomy, a homeostatic approach, 2nd ed, John Clancy and Andrew McVicar (eds), Edward Arnold, London, 1995, currently in print.

Myalgic encephalomyelitis--a persistent enteroviral infection?

Myalgic encephalomyelitis is a common disability but frequently misinterpreted. Amongst 6,000 patients referred for general microbiological diagnosis between 1975 and 1987, 420 cases were recognized. Coxsackie B neutralization tests, in 205 of these, demonstrated significant titres in 103/205 (50%), while of 124 additionally investigated for enteroviral IgM, 38/124 (31%) were positive. This illness is distinguished from a variety of other post-viral states by an unique clinical and epidemiological pattern characteristic of enteroviral infection. Prompt recognition and advice to avoid over-exertion is mandatory. Routine diagnosis, specific therapy and prevention, await further technical advances.

Exploring the benefits of medical record automation.

During the past two years University Health Center, Burlington, VT., has been involved in the development and testing of a problem-oriented automated medical record. Although the achievements to date have largely been predicated on the effective use of the sophisticated computer technology, the system's basic premise and foremost requirement remains simply to improve the collection and presentation of patient clinical information.

Effects of phosphate limitation of growth on the cell-wall and lipid composition of Saccharomyces cerevisiae.

The phosphorus content of phosphate-limited Saccharomyces cerevisiae was only 71% of that of non-limited yeast. Walls prepared from phosphate-limited cells contained slightly less phosphorus than control walls. No evidence was obtained for the presence in these walls of uronic acid or succinyl residues. The carbohydrate content of walls of phosphate-limited yeast was less than that of non-limited walls, and this was reflected in a decreased glucan content. There was only a slight decrease in glucosamine content while the protein content increased. The major change in the lipid composition of phosphate-limited yeast was a decrease in both sterol esters and triacylglycerols. There was a decrease in total lipid content, but increased production of phosphatidylethanolamine and phosphatidylcholine. The phosphatidylserine content was decreased. These results suggest that there are fewer intracellular low-density vesicles in phosphate-limited yeast.

Clinical and biochemical findings in ten patients with benign myalgic encephalomyelitis.

Ten patients in whom the clinical findings were consistent with the syndrome variously described as 'benign myalgic encephalomyelitis', 'epidemic neuromyasthenia', 'Royal Free disease' and 'Icelandic disease' were investigated for blood levels of myoglobin and various enzymes. Although there is no clinical resemblance between the two diseases, the biochemical pattern bears a close similarity to that found in Duchenne muscular dystrophy (DMD) though differing sharply in that no rise in creatinine kinase levels was found. These findings are discussed with particular reference to recent suggestions that the permeability of cell membranes may be impaired by changes in intracellular energy mechanisms.

Aeromonas hydrophila sepsis in a patient undergoing hemodialysis therapy.

Aeromonas hydrophila septicemia complicated by a generalized cutaneous vasculitis developed in a patient receiving home hemodialysis therapy. Because the Aeromonas organism is found in many natural water sources, the possibility that this patient's hemodialysis system became contaminated was explored. Although cultures from the patient's home environment showed no Aeromonas sp, the possibility still exists that the site of contamination was in the dialysis system.

'Epidemic neuromyasthenia' 1955-1978.

A record of fifty-three patients admitted to the Infectious Diseases Department of the Royal Free Hospital between April 1955 and September 1957 suffering from 'epidemic neuromyasthenia' establishes the fact that the condition was endemic in the general population before, during and after the outbreak among the staff of the hospital. A further outbreak occurred in North Finchley between 1964 and 1967 and sporadic new cases are still being encountered. The majority of these patients show evidence of involvement of the central and sympathetic nervous systems and the reticulo-endothelial system. Abnormal muscular fatigability is the dominant clinical feature and it is suggested that mitochondrial damage may provide an explanation for this phenomenon. Enzyme tests carried out in seven cases show pathologically high levels of lactic dehydrogenase, and glutamic oxalo-acetic transaminase. A follow-up study suggests that there is one group of patients that recovers completely or nearly completely, a second that recovers but is subject to relapses and a third that shows little or no recovery, these patients remaining incapacitated.
