In France, smallpox and poliomyelitis have almost disappeared thanks to generalized vaccination, no case of small pox has been reported since 1975. 17 cases of poliomyelitis were reported in 1975. These two vaccinations remain compulsory. The prophylaxis of measles, which is a very common disease, is based on vaccination recommended for young children, particularly those living in groups. The frequency of severe forms of flu is reduced by vaccination which is advised in the elderly and in weak or exposed subjects. Rubella raises the problem of contamination of pregnant women. It is recommended to vaccinate young girls and also, after serological reactions, women who are professionally exposed to the disease. Epidemic virus hepatitis (virus A) is increasing in frequency, whereas transfusion hepatitis is becoming less common since the strict application of measures of prophylaxis. The spread of rabies, mainly in the fox, is worrying for public health workers. No case of human rabies has been noted in France. Preventive anti-rabic treatment is applied in the case of a patient bitten by a suspicious animal.

The conditions for a sensitive and specific solid-phase radioimmunoassay (RIA) for the detection of IgM antibodies to hepatitis A virus (HAV) were optimized, and the RIA was used to assay sera from patients with hepatitis. IgM antibodies to HAV reached highest concentrations between one and three weeks after onset of icterus and were measurable in follow-up sera for at least 12 months after infection. To prove the specificity, the IgG antibodies were separated from patient sera by sucrose density-gradient centrifugation. The remaining IgM antibodies, after treatment with beta-mercaptoethanol, did not bind in the RIA, and, when the anti-IgM antibody bound to the solid phase was replaced with anti-IgG, a negative result was obtained with incubation of IgM antibody to HAV. Also, the presence of IgG was shown not to interfere with measurement of IgM antibody to HAV. Finally, as a further specificity control, 50 sera positive for rheumatoid factor or from patients infected with hepatitis B virus, cytomegalic inclusion disease, infectious mononucleosis, influenza A virus, rubella, or measles were tested, and all of these sera were negative for IgM antibody to HAV.

Rubella antibody titers were determined pretransplant and then serially posttransplantation in 52 consecutive patients whose renal allografts survived at least three months. Group A patients (18) had antibody titers greater than or equal to 1:128 in the posttransplant period. Group B (24) had intermediate antibody titers that never rose higher than 1:64. Group C (10) consistently had antibody titers less than 1:8. Group A did not differ from groups B and C with respect to age, race, sex, type of transplant, underlying renal disease, or maximum complement fixation antibody titers posttransplant to cytomegalovirus or herpes simplex virus, type 1. Group A did differ from groups B and C in its frequency of hepatitis, chronic liver disease, episodes of late rejection (greater than or equal to 21 days after transplant), transplant nephrectomy required for rejection, infections whose defense involves intact cell-mediated immunity, and the number of late rejection episodes per patient. Mechanisms underlying these associations are not known but apparently are not related to HLA phenotype.

The state of hygiene in a dental office in the canton of Bern was examined. 22 bacteriological tests were made on the surfaces around the treatment area. Also, the water from the sprays and the most important instruments were tested. Before cleaning and disinfection the test objects showed an average of 110 microorganisms per 100 cm2. The species are enumerated. Particularly infected were polishing brushes, "slurry-water", dentures polished and cleaned with water, also the water from the dental unit. The results show that improvement is badly in need. Also a warning is given for the possible transmission of hepatitis. Female dentists and dental assistants are cautioned to get a german measles vaccination.

In accordance with the system of viral species, viral disorders of the oral mucosa may be classified with regard to their intensity of affection. There are but few viral infections exclusively affecting the oral mucosa like e.g. 1. Glossitis papulosa of Michelson, representing a special form of vaccinia inoculata, 2. Gingivo-stomatitis herpetica and 3. warts of the mucosa or condyloma-like papillomas of the oral mucosa including oral papillomatosis, that, itself shows morphological and clinical similarities to laryngeal papilloma. A second group of disorders mainly affecting the oral mucosa includes the "Aphthoid of Pospischill and Feyrter", Zahorsky's herpangina and other viral infections by the Coxsackie group, like vesicular stomatitis. The 3rd group represents viral infections of other organs in which affection of the oral mucosa is a prerogative, e.g. smallpox, varicella, foot-and-mouth disease and pharyngo-conjunctival fever. A 4th group includes those viral infections of the organs in which co-affection of oral mucosa occurs frequently or once in a while (at occasions). Here, we find eczema vaccinatum, herpes zoster, herpes simplex of the oral mucosa mostly on the hard palate, eczema herpeticatum, post-herpetic Erythema exsudativum multiforme, Mononucleosis infectiosa Pfeiffer, viral flu, German measles, parotitis epidemica, rubeola and ECHO-exanthema. A 5th and last group is made up by viral infections of other organs, in which affection of the oral mucosa hardly occurs at all. This group contains paravaccinal Ecthyma contagiosum, poliomyelitis, viral infection of the city of Marburg and some Arbovirus infections. Relatively few viral disorders never co-exist with lesions on the oral mucosa like e.g. Virus-hepatitis or some viral encephalitides. Groups 1 and 2, most important of all, are presented in detail regarding clinics, diagnostics, differential-diagnosis and therapy. The disorders within the other 3 groups are discussed only regarding their importance in the field of ENT-related symptoms of the oral mucosa. A number of pictures and tables completes important clinical details and give further hints to their differential-diagnosis.

Six girls and one boy with cronic active hepatitis (CAH) of unknown etiology were between 9 and 15 years at the clinical onset of their illness. After beginning immunosuppressive therapy the course of their disease was followed from one to ten years. All had markedly increased IgG, high titres of smooth muscle antibodies (SMA) and antinuclear antibodies of IgG class in the earliest serum specimens tested. Therapy resulted in an improved sense of well-being and a decrease in SGOT, IgG and titres of SMA. Very high titres of measles antibodies were observed in all cases. In one of the cases CAH manifested itself after measles and in another after rubella infection. The first case in our series of patients died of liver failure after 5 years of illness. The other patients have survived and are able to live a normal life. The possibility of CAH should be considered when children develop symptoms of hepatitis. Longterm immunosuppressive treatment with regular clinical and laboratory evaluation is important. Estimation of titres of SMA is an additional parameter of value in following of the activity of CAH in these young patients.

High antibody titres against rubella and measles viruses have recently been associated with certain chronic disorders such as chronic active hepatitis and occasionally with acute hepatitis. The present study was designed to evaluate the frequency of this association with acute hepatitis. Haemagglutination inhibition (HI) and complement fixation (CF) antibodies to rubella, measles and influenza A viruses were determined in 97 consecutive patients with acute viral hepatitis and in 97 control persons matched by sex and age. In patients, particularly in those over 30 years of age, a small but statistically significant increase in rubella HI titres was seen. In 3 hepatitis cases the rubella HI titres were very high (greater than or equal to 2 560). The antibody levels against measles and influenza A viruses did not differ from the controls. The present data indicate that a small proportion of acute hepatitis patients show a transient strong humoral immune response to rubella virus. The reason for this is not known.

One of the most important aspects of preparing travelers for destinations throughout the world is providing them with immunizations. Before administering any vaccines, however, a careful health and immunization history and travel itinerary should be obtained in order to determine vaccine indications and contraindications. There are three categories of immunizations for foreign travel. The first category includes immunizations which are routinely recommended whether or not the individual is traveling. Many travelers are due for primary vaccination or boosting against tetanus-diphtheria, measles-mumps-rubella, pneumococcal pneumonia, and influenza, for example, and the pre-travel visit is an ideal time to administer these. The second category are immunizations which might be required by a country as a condition for entry; these are yellow fever and cholera. The final category contains immunizations which are recommended because there is a risk of acquiring a particular disease during travel. Typhoid fever, meningococcal disease, rabies, and hepatitis are some examples. Travelers who are pregnant or who are infected with the human immunodeficiency virus require special consideration. Provision of appropriate immunizations for foreign travel is an important aspect of preventing illness in travelers.

A computer-assisted comparative analysis of the amino acid sequences of (putative) thiol proteases encoded by the genomes of several diverse groups of positive-stranded RNA viruses and distantly related to the family of cellular papain-like proteases is presented. A high level of similarity was detected between the leader protease of foot-and-mouth-disease virus and the protease of murine hepatitis coronavirus which cleaves the N-terminal p28 protein from the polyprotein. Statistically significant alignment of a portion of the rubella virus polyprotein with cellular papain-like proteases was obtained, leading to tentative identification of the papain-like protease as the enzyme mediating processing of the non-structural proteins of this virus. Specific grouping between the sequences of the proteases of alpha-viruses, and poty- and bymoviruses was revealed. It was noted that papain-like proteases of positive-stranded RNA viruses are much more variable both in their sequences and in genomic locations than chymotrypsin-related proteases found in the same virus class. A novel conserved domain of unknown function has also been identified which flanks the papain-like proteases of alpha-, rubi- and coronaviruses.
