[The impact of a sore throat score on clinical management of streptococcal angina].

Objective: To establish the validity and the role of a clinical sore throat score in clinical management of streptococcal angina on a first visit to a primary care provider.

Methods: This study included 168 patients. The sore throat score had 5 criteria: age, fever, absence of cough, tender anterior cervical nodes, tonsillar swelling or exudate.

[The distribution of anaerobic morpho-types in sub gingival plaque associated with periodontal disease].

The authors' goal has been to establish the distribution of anaerobic morpho-types in sub gingival plaque collected from patients with periodontal disease. The study included 26 patients. Samples of sub gingival plaque were transported in thioglycolate broth.

[Methods of microbiological diagnosis in periodontal disease].

Microbiological findings together with clinical and radiological diagnosis are essential for rationale use of antibiotics in periodontal disease. Methods used for microbiological diagnosis are: microscopy, cultivation, gas liquid chromatography, PCR, immuno-assays (ELISA, immunofluorescence), FISH. Each of them has some advantages and disadvantages related to cost, accessibility, sensitivity, duration.

Bioactive polymers: in vitro and in vivo study of controlled release neomycin.

Neomycin is coupled on xanthan-a polysaccharide of microbial biosynthesis produced by Xanthomonas campestris-through ionic complexation. The kinetics of neomycin release, in vitro, at pH = 8.2 is studied.
