[Observational research on the dental compliance of growing children. A behavioral analysis].

Epidemiology has always focused attention on analysis of environmental variables, in addition to biological or physico-chemical elements, that affect the onset and development of dental pathologies. However, other environmental events, such as behavioural repertoires, that may interfere with medical treatment, reducing the chances of recovery, have never been analysed. This study, which was performed in two groups of children aged between six and ten who were examined either inside or outside to school setting, aimed to identify, in addition to the incidence of dental pathologies, the frequency of occurrence of those patterns that risk developing into non-compliant behaviour repertoires to the dentist setting. Results show a generalised response of fear and anxiety in both groups, particularly in older children. It is suggested that the prevention of biological as wall as maladaptive behavioural patterns might lead to a reduction of the social burden determined by the cost of medical care.

The quantitative determination of neomycin sulphate by a diffusion technique on agar plates by the method of the European Pharmacopoeia, 2nd edition--evaluation of precision and reproducibility of the method.

The medium recommended by the European Pharmacopoeia (EP), 2nd edition, for the microbiological determination of neomycin by the agar diffusion method was tested and compared with the medium recommended by the EP, 1st edition. The tests were carried out in different laboratories. The medium recommended by the EP, 2nd edition, gave greater precision and reproducibility than the previous medium. The possibility of using a reference standard of almost pure neomycin B for both the determination of framycetin and neomycin was evaluated. The results demonstrated that the medium recommended by the EP, 2nd edition, gave better precision and reproducibility. Difficulty in achieving valid assays was practically the same with both media.

The role of mycoplasmas in sexually transmitted vaginitis.

Mycoplasmas were isolated from 325 female subjects who came to a gynaecological out-patient clinic for many different reasons. Micro-organisms can also be isolated in a high percentage from apparently healthy subjects. Our data indicate that mycoplasma can be either simple commensals in the uro-genital apparatus or saprophytes. In vulvo-vaginitis mycoplasma can cause a type of pathology which is always associated with the presence of other pathogens.

[Bacteriological study at the vaginal level in sexually active women].

We have studied the microbiological environment of the vagina in 202 sexually active women when they came into an outpatient gynecological hospital. By some specific bacterioscopic and cultural examinations we have tried to understand the pathological role of some microrganism in sexually transmitted diseases. An elevated incidence of mycoplasm in asymptomatic subjects has shed light on the probable saprophytic behaviour of these microrganisms.

[Standardization and stability of reagents for the titration of anti-tetanus antibodies by means of the passive hemagglutination technic].

The evaluation of the antitetanus immunity in human sera is of primary importance for the carrying out of an adequate prophylaxis and treatment of tetanus. Tetan Test is a diagnostic kit for the titration of the antitetanus antibodies, by means of the passive hemagglutination technique. Tetan Test is examined under the point of view of the preparation techniques and the process and final controls which warrant the quality and the standardization of the product itself. The stability of Tetan Test, after storage at the temperatures: 67 degrees C, 52 degrees C, 37 degrees C, 22 degrees C is evaluated. The excellent results obtained allow the use of the product also in hot climates, in developing countries, where the storage at the advised temperatures is not possible.
