Detection of Vibrio cholerae biotype El Tor by purging.

Previous studies have demonstrated the value of purging in detecting inapparent cholera infection, but the technique has not been generally accepted. The present study shows that the method can be recommended as a routine procedure to determine when convalescent cholera patients should be discharged from hospital. It may also be useful in detecting carriers of Vibrio cholerae and for evaluating chemotherapy. In this study, five of the eight patients who excreted vibrios after purging had been treated with 2 g of chloramphenicol daily for three days, a finding that throws doubt on the adequacy of this treatment. Purging with magnesium sulfate is simple, well tolerated and ideal for hospitalized patients or for subjects whose stools can be promptly cultured. Since magnesium sulfate is inhibitory to Vibrio cholerae, this purgative is not well suited for field studies, where there may be delays in culturing.

Search for a mass chemotherapeutic drug for cholera control. A study of Vibrio excretion following single and multiple dose treatment.

In a study designed to seek a suitable drug for mass chemotherapy during a cholera epidemic, four drugs were administered in single doses to patients with cholera in Iran. Streptomycin was administered orally; penicillin, parenterally; and chloramphenicol and a long-acting sulfa drug, both orally and parenterally. No drug consistently eliminated vibrios from the intestinal tract. Chloramphenicol was also administered in multiple doses for three days; this also failed to eliminate vibrios in one-third of 25 patients studied. The major problem with these drugs administered orally seems to be rapid elimination and poor absorption by patients with diarrhoea. The authors do not recommend any of these drugs for single-dose mass chemotherapy and consider that chloramphenicol cannot be recommended for multiple-dose mass chemotherapy.

Intravascular malignant lymphomatosis (so-called malignant angioendotheliomatosis): a case confined to the lumbosacral spinal cord and nerve roots.

Intravascular malignant lymphomatosis (IML), so-called malignant angioendotheliomatosis, was found in lumbosacral spinal cord and nerve roots of a 78-year-old women who died one month after the onset of symptoms. With regard to the majority of the 37 reviewed neurological cases in the literature, this report is unusual in that the disease was exclusively localized in the spinal cord and systemic involvement was absent. The usual clinical hallmark of the disease is a subacute dementia or encephalopathy, often associated with focal neurological signs, culminating in death within several months. The pathological features of IML characteristically include multiple small foci of necrosis of the whole brain, caused by occlusion of small vessels by noncohesive neoplastic cells and secondary changes of the vascular wall. All organs may be involved, especially the skin and the adrenals, sometimes with tumoral formations. Despite the fact that lymphoid tissues are usually spared, recent reports and the present case strongly suggest a lymphoid rather than endothelial origin of the malignant cells. The pathogenesis of this mainly intravascular lymphoma remains obscure.
