A case is described of herpetic hepatitis in a pregnant woman with primary herpetic stomatitis. Intranuclear inclusion bodies and virus particles were found in hepatocytes, and herpes virus was isolated from a liver biopsy and from oral swabs but not from blood. From rising titres of neutralizing and complement-fixing antibody it is concluded that the oral infection was a primary one. Factors predisposing to the hepatitis are discussed.

A considerable amount of information has accumulated during the past 10 years in the search for antiviral agents. Ribavirin and inosiplex are 2 interesting developments to come out of this search. Ribavirin, a synthetic nucleoside, has an unusually wide spectrum of antiviral activity, especially when tested in vitro. A large number of RNA and DNA viruses are sensitive, especially herpes viruses, poxvirus, influenza, parainfluenza, reovirus, togavirus, and RNA tumour viruses. The in vivo antiviral spectrum of activity is much narrower, with activity against herpes virus, influenza, parainfluenza, measles and adenoviruses. However, controlled clinical trials have not been uniformly successful in treating influenza, hepatitis, herpes simplex and herpes zoster. Inosiplex has been shown to have antiviral activity in vivo against influenza, herpes simplex, rhinovirus and vaccinia virus infections. However, antiviral activity has not been consistently demonstrated, and this observation led to further studies which revealed its immunomodulating effects. The accumulated evidence has indicated that inosiplex is more a prohost agent rather than an antiviral drug. Immune functions which are depressed during viral infection can be restored to normal by inosiplex therapy. At present, neither ribavirin nor inosiplex alone has been shown to be uniformly successful in the treatment of human viral diseases. Nevertheless, their potential place in chemotherapy should not be neglected, although further data are needed to determine what this place will be. Whether combining them with other antiviral agents such as interferon, acyclovir, Ara-A, and so on, would produce a potentiation of action and improved antiviral chemotherapy, will be an interesting area for further study.

Methisoprinol (Isoprinosine), a purine derivative, has been shown to exert a number of immunopharmacological effects, both in vitro and in vivo, in animal and human studies. The agent, somehow mimicking the effects of thymic factors, induces the appearance of phenotypic markers of differentiation on immature precursor T cells; enhances the proliferative response of murine and human lymphocytes to mitogens or antigens, augments helper or suppressor T cell functions and increases the production of lymphotoxin a lymphokine. It has also been shown that this drug can potentiate the effects of macrophage activating factor to stimulate macrophage, and of interferon to protect mice against experimental viral and tumor challenges. In humans, beneficial results have been reported from clinical trials testing the effects of methisoprinol in a variety of diseases including subacute sclerosing panencephalitis (SSPE), acute viral encephalitis, recurrent mucocutaneous infections due to type I and II Herpes viruses as well as in immune restoration of cancer patients with immunodepression following radiotherapy. The drug is also being studied in immunopathological disorders such as rheumatoid arthritis, systemic lupus erythematosus. Sjogren's disease and type A hepatitis. The large spectrum of effects of methisoprinol on a number of immune parameters, the increasing evidence of its therapeutic value in several pathological conditions and its safety of use qualifies this drug as an interesting immunoregulating agent.

The induction in mice of a sterile subcutaneous granuloma exerted no influence upon the mortality following their infection with herpes type 1, murine hepatitis or encephalomyocarditis viruses. Attempts to reproduce the resistance -- which has been found to occur as a result of the granulomatous reaction, in the case of bacterial, fungal or protozoa infections and tumour invasions -- by varying the route and timing of the virus inoculation or the strain of mice have failed. We conclude that it is not merely through their inflammatory properties that some non-specific immunostimulating substances enhance resistance against viral infection.

As early syphilis becomes more uncommon in the community, it will present frequently to the tertiary hospital as a diagnostic problem. Twenty patients with classic signs and symptoms of primary and secondary syphilis in whom the correct diagnosis was initially missed are presented. The importance of a routine admission Venereal Disease Research Laboratory test (VDRL) in making the correct diagnosis is emphasized. The laboratory techniques for diagnosing syphilis and recommended treatment schedules are presented. Clinical manifestations of herpes progenitalis, problems with pregnancy and association with cervical carcinoma are also presented. Enteric diseases (hepatitis, shigellosis, giardiasis and amebiasis) as sexually transmitted diseases in homosexual men are summarized.

The authors report the case of a 46-year old patient who died from fulminant herpetic hepatitis. No cause of immuno-depression was documented in this patient. No skin or mucosal herpetic lesion was found except a questionable urethritis. Herpes virus was demonstrated in the hepatocytes by electron microscopy and isolated from the serum. It was identified as herpes virus hominis type II. The low titer of circulating antibodies did not permit the distinction between herpetic primo-infection and reactivation. The features of the hepatic injury are discussed and compared with previous reports. An active diagnostic approach of herpetic hepatitis is considered.

The TORCH group: toxoplasma, rubeola, cytomegalovirus (CMV), herpes virus hominis (HSV) and also the B-virus of hepatitis (HBV) determine congenital malformations in the newborns. For this reason, the Authors leaded an epidemiologic study testing with some antibodies (anti-TORCH and anti-HBV) the serum of groups of mother-newborn of the Obstetrical Clinic of Palermo. This study became manageable because now there are available high specific immunoenzymatic methods, for example ELISA, the passive haemoagglutination and the haemoagglutination-inhibition. In our people, high concentration of rubeola, HSV and CMV and very low concentration of toxoplasma and HBV are shown. The frequency of malformation is related with the subclinical infection. The Authors suggest to extend same investigation at an higher number of pregnant women to prevent these congenital malformations.

Each time the handpiece turbine is stopped while the bur is still in the patient's mouth, almost 1 ml of microbe-laden oral fluids may be aspirated into the average dental unit water line by the retraction valve present in the dental unit. This fluid may contain an average in excess of 54,000 microorganisms per milliliter, including both facultative and obligate anaerobic bacteria of medium to high virulence. Other infectious agents including hepatitis, herpes, influenza, and other upper respiratory viruses may also be present. This germ-laden water may then be sprayed into the mouth of the next patient, possibly initiating an oral or upper respiratory tract infection. Sterilizing the handpiece between appointments, although of great significance in the prevention of disease transmission, will not totally eliminate the problem discussed here as almost 95% of the oral fluid aspirated into the dental unit went past the handpiece and into the handpiece cooling water line. Complete elimination of the retraction valve in the unit is the most effective means of solving this problem, but, with present dental unit designs, this may result in water dripping onto the patient. A viable alternative is the installation of a check valve (anti-retraction valve) downstream from the retraction valve. Installation of a check valve resulted in an almost 4,000-fold decrease in this contamination. The attachment of a check valve will have no effect on normal less virulent bacteria already present in tap water. These bacteria colonize the water lines of the dental unit and are then continually shed into the water in numbers often as high as 1,000,000 CFU/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

The review reflects the concerns of researchers of the "Stefan S. Nicolau" Institute of Virology who used electron microscopy techniques with a view to visualizing morphological features of virus structure (influenza, adeno, hepatitis, herpes, cytomegalic, Aujeszky, rabies viruses, etc.) and different aspects of the virus - host cell relationships (Sendai virus/Hep2 cells, influenza and adenovirus/mouse lung, subacute sclerosing panencephalitis/human brain or cell cultures, Coxsackie and foot-and-mouth disease virus/myofibrils, Rubarth hepatitis virus/chick embryo liver cells, a.o.). Morphological aspects of normal or tumoral cells and the influence of chemical agents (actinomycin D, EDTA), viruses, bacteria or parasites have also been studied. Mention is made of several original techniques used to obtain electron microscopy preparations.

A series of 248 consecutive patients undergoing cardiac surgery were examined in a prospective study of post-transfusion hepatitis in a single British centre. Patients received a total of 1796 units of blood or blood products (mean blood transfusion 6.28 units per patient). During five to 30 days after operation 38 of the patients showed an increase in serum transaminase activities. There was no serological evidence for fresh infection by hepatitis A or B virus, cytomegalovirus, Epstein-Barr virus, or herpes virus in any of these patients. The increase in transaminase activities was unexplained and reached over 100 IU/l (normal less than 40 IU/l) in six patients. The incidence of acute short incubation post-transfusion non-A, non-B hepatitis was therefore thought to be 2.4%. These six patients had normal liver function six months after transfusion but a further two of the surviving 228 patients had raised serum transaminase activities at six months. In one of these, liver biopsy disclosed chronic persistent hepatitis; in the other, alcoholic liver disease was suspected. The incidence of significant chronic liver disease after blood transfusion possibly attributable to a non-A, non-B hepatitis agent was therefore only 0.4%.
