Recurrent epidemic hepatitis A associated with consumption of raw shellfish, probably controlled through public health measures.

Between April 1984 and January 1985, in the Italian seaport of Livorno, the annual incidence of serologically confirmed acute hepatitis A doubled to 46 per 100,000 population. The exposure histories of each of 75 jaundiced subjects with serologically confirmed hepatitis A were compared with up to four, randomly chosen-, age-, sex-, and neighborhood-matched controls. Illness was strongly associated with consumption of raw mussels and clams within six weeks of onset of illness.

[Statistical and epidemiological studies on cases of infectious mononucleosis treated in the Infectious Diseases Division of the Livorno Hospitals between 1964 and 1977].

Reference is made to a series of 133 patients with infectious mononucleosis admitted to a hospital department over a period of 14 yr. The incidence of the disease is assessed in terms of sex, age, season, and occupation. Its duration and the average length of hospital stay are also computed.

[Clinical and hematological manifestations of infectious mononucleosis. Personal cases].

An account of the incidence and features of fever, angina, adenopathy and splenomegaly in infectious mononucleosis is followed by an explanation of the importance of palpebral oedema, nasal obstruction, and exanthema and enanthema, the characteristics of which may prove of diagnostic assistance. Attention is drawn to the presence of maculopapular and itching exanthema, particularly after semi-synthetic penicillins. An assessment is also made of liver, myocardial and renal changes, since it is felt that involvement of these organs is an integral part of the clinical picture.

[Australia antigen and viral hepatitis. Clinico-statistical considerations].

204 cases of viral hepatitis, 192 related to the MS1 form and 12 to MS2, were studied for the presence of Au. antigen and possible relations between this and the course of the disease. The antigen was encountered in 12 cases of the first group (6.

[Case of severe renal insufficiency appearing during a course of viral hepatitis].

Notes on the literature data concerning renal alterations observed in the course of virus diseases, and on the results of experiments designed to show the nephrotoxic action of viruses and their possible investigation of certain nephropathies, are followed by the presentation of a case of serious renal insufficiency in a young woman with virus hepatitis. The clinical data, the history and the results of blood chemistry and function tests showed this to be attributable to glomerulonephritis, probably caused by the same virus.
