CIRRHOSIS OF THE LIVER—Clinical Course in 2,377 Patients at San Francisco General Hospital

The records of 2,377 patients with Laennec''s cirrhosis were reviewed for the period 1947-1957. The chief presenting symptom was ascites in 46 per cent, bleeding in 23 per cent, coma in 18 per cent, jaundice in 9 per cent, and both jaundice and ascites in 4 per cent. Nearly half of the patients died during the period under study—one-third from hepatic failure, one-third from gastrointestinal bleeding, and one-third from other causes, most of which were related to alcoholism.Massive gastrointestinal bleeding occurred in 21 per cent of the patients at some time in their clinical course, and in the 10 per cent of these in whom ulcer was demonstrated, one-fifth died as a result of the hemorrhage. Of those presumed to be bleeding from esophageal varices, 64 per cent died at the first hemorrhage and 10 per cent at subsequent hemorrhages; 85 per cent of all those who bled from varices were dead at the end of one year, and 91 per cent were dead at the end of three years.The survival curve of a group of patients who bled once and were good operative risks but had received no operative treatment was compared to the survival curve for entire group who survived the first hemorrhage. The three-year survival in the good risk group was 47 per cent; for the group as a whole it was 30 per cent. The difference in mortality rate was primarily due to an increased number of deaths from hepatic failure in the combined group, whereas 60 per cent of the good risk group died of recurrent gastrointestinal hemorrhage.As 86 per cent of those who were to die of gastrointestinal bleeding did so at the first hemorrhage, it was concluded that any decided improvement in the salvage rate achievable by operation must come from some means of diagnostic forecast of the likelihood of bleeding, with resort to prophylactic operation in such cases.     

Allescheria boydii and Aspergillus fumigatus Skin Test Antigens

May, Lewis K. (Woman's Medical College of Pennsylvania, Philadelphia), Ralph A. Knight, and H. William Harris. Allescheria boydii and Aspergillus fumigatus skin test antigens. J. Bacteriol. 91:2155-2157. 1966.-Protein and polysaccharide fractions were extracted from culture filtrates of Allescheria boydii and Aspergillus fumigatus by the methods of Seibert and of Heidelberger, and injected intradermally into guinea pigs previously infected with these fungi. The diameter of erythema and induration was determined at 8, 24, and 48 hr. The protein and polysaccharide antigens yielded specific skin reactions in homologously infected guinea pigs. Erythema appeared at 8 hr with both the protein and polysaccharide antigens. At this time, the polysaccharide skin tests showed erythema and a central blanched wheal. A similar wheal was not observed with the protein. The erythema of the polysaccharide reaction began fading at 24 hr, whereas the protein reaction remained unchanged through 48 hr with both antigens. In guinea pigs, the area of erythema was more constant and thus easier to measure than was induration.     

Cerebrovascular Occlusive Disease—Experience with Panarteriography in 300 Consecutive Cases

Three hundred patients with cerebrovascular occlusive disease have had cerebral angiographic examination at the Veterans Administration Hospital, San Francisco, in the last five years. The present technique consists of preliminary visualization of the aortic arch and the major extracranial branches, followed by selective study of the subclavian and carotid arteries as necessary for evaluation of the intracranial circulation.Nine major complications occurred (an over-all incidence of 3 per cent). Two patients died after angiography and seven had major neurologic deficits persisting for more than 24 hours. Three of these patients had permanent damage, but four recovered completely.One-third of the patients had extracranial disease and one-third had intracranial disease. No significant lesion was found in the remainder. In the 212 patients with lesions, multiple lesions were common, the average number being three. Six patients had brain tumors and five had aneurysms.The mechanism of the stroke could be ascertained readily in most of the patients, but the extent of the disease and the resulting symptoms varied considerably. Several patients with occlusion of most of the cerebral vessels had minimal symptoms, while others had catastrophic symptoms but only minimal findings at arteriography.
