Immunity to diphtheria in the 4-70 year age group in Italy.

Diphtheria antibody level in serum samples obtained from 270 subjects aged 4-70 was measured by in vitro seroneutralization test on Vero cells. Of the studied population, 27.8% had an antibody titre below the protective level (< 0.01 IU/ml). The prevalence of susceptible subjects showed a significant age-related increase (p < 0.01), with the highest value (53.8%) in the 31-40 age group. Mean antibody titre was maximum in individuals aged 13-14, then decreased reaching the minimum level in the 41-50 age group. These data suggest that in individuals aged 30-50, diphtheria immunity is not satisfactory, both for prevalence of immune subjects and for antibody levels. Therefore, a revaccination of adults with reduced doses of diphtheria toxoid may be advisable.

Tetanus immunity in a partially vaccinated population of children in a district of Naples (Secondigliano).

A general opinion is that compliance with the compulsory immunization programme of children is excellent in Italy. We have studied antitetanus immunity in relation to vaccination history in a sample of 444 school children born between 1977 and 1981 in a district of Naples. Information on vaccination history was collected by interviewing the parents and validated using the official vaccination certificates. Titration of antibodies against tetanus was carried out by the immunoenzymatic method. 0.9% of our study subjects had not been vaccinated at all and only 21.2% had received 4 vaccine doses. In 18 children the presence of antitetanus antibodies was not detected; 14 of them had received one or more doses of vaccine. The lack of compliance with the vaccination programme was associated with a remarkable delay in administering the tetanus vaccine. In the population reported here, the percentage of subjects only partially covered is higher than that found in other regions of Italy.

Detection of anti-HIV antibodies in immunoglobulin preparations: the significance of antibodies to the HIV-envelope.

Four hundred and sixty-eight immunoglobulin preparations, produced between 1969 and 1989, were examined for anti-HIV antibodies by means of two competitive immunoenzymatic assays and the Western blot test. This study refers the results obtained by the three different methods. Such results show that the detection of anti-HIV antibodies in immunoglobulins may be performed on a routine basis using commercial kits intended for human sera. The meaning of the test and the role of antibodies against the HIV envelope proteins are emphasized.

[Nutrition errors in children].

Errors in the childhood feeding administration are commonly met, particularly during the first and second year of life, according to the poor or vague knowledge among paediatricians. A first proof of this assumption is given when, as a consequence of digestive disturbance, caused by a wrong nourishment, the paediatrician suggests remedies that, substantially, make the same primitive mistakes. A second proof is given when a particular diet, due to the presence of intestinal disturbance and already seen to be inefficacious, is reproposed, even more than once, with industrial aliments which differ from the ones used in the name and the brand but not in the composition. Finally, another proof is given when in the exclusion therapy due to an intolerance towards gluten, towards cow's milk, towards disaccharides, the paediatrician inserts, in the diet, products containing, respectively, the above mentioned components. These and other mistakes are reported in the present casuistry (121 cases), the majority of which (75 cases) is accompanied by specific examples. Between the cases that mostly stand out we find the so called "precocious weaning" as cause of digestive disturbance and, frequently, as initial moment of a chain of errors responsible, in their turn for the protraction and the chronicization of the aforementioned intestinal pathology.

[Herpesvirus simplex disease in the newborn infant. Clinical aspects, diagnosis, prophylaxis, therapy].

Herpes Simplex virus infection (Particularly by HVS2) is one of the most important disease transmitted by mother to newborn because of the seriousness of symptoms and the high incidence of genital infection of pregnants. Transmission of congenital HVS infection occurs usually by contact with infected genital secretions during the birth process, but there is evidence that transplacenter transmission also may occur. Emphasis must be placed then on prophylaxis of genital infection of pregnants and of their partners. Specific Immunoglobulins with high antibody titre are recommended for prophylaxis. An anti HVS2 vaccine without oncogen property os still at experimental stage. This prophylaxis is inadequate for the newborn of infected mother: this one must be treated with newer antiviral agents (Acyclovir), even is absence of herpetic lesion and other symptoms.

[Sinusitis in children. Personal case study].

The presence of sinusitis has been found out 85 times out of 278 cases of acute relapsing respiratory diseases in children between 4 and 12 years of age. The maxilla sinuses have been those most frequently stricken; the frontal sinuses come next and last at a distance the sphenoidal sinus. A close relationship between the entity of basic respiratory pathology and the presence and seriousness of the sinusitis has been observed. There also seems to be a rather close relationship between the frequency of the presence of sinusitis in children with respiratory pathology either relapsing or chronic and climatic environmental situation. A damp climate with persistent fog together with industrial atmospheric pollution seems to favour the considered pathology in an undisputed way.
