[New attachment formation with guided tissue regeneration. Review of the literature].

Restoring gum epithelial-conjunctive attachment on calcified tooth surfaces is the main objective of every treatment program of periodontal lesions. Research works are resulting today in a better understanding of biological mechanisms involved in tissue healing or rebuilding processes. These scientific studies allow to control such new therapeutics that can create a biocompatible environment essential to the metabolism of regenerating cells.

[Increase of blood lead in alcoholism. Relation with blood pressure].

Blood lead levels and blood pressure were measured on admission in 161 chronic alcoholic patients (121 men and 40 women) hospitalized for detoxification. The mean lead level was 280 micrograms/l and the highest value, in one patient, was 725 micrograms/l. These figures were as high as those of subjects under occupational exposure to lead. Blood lead level was correlated with blood pressure, and the statistical correlation appeared to be independent. Blood lead level was also correlated with serum gamma-glutamyl-transferase concentration and with the mean corpuscular volume. Wine drinkers had higher blood lead level than beer and/or liquor drinkers (mean: 298 micrograms/l versus 225 micrograms/l respectively), which fits with the higher lead content of wine.

[Arsenous anhydride poisoning. Peripheral neuropathy and changes in cognitive functions].

The authors report the evolution over an 11 months period of a case of subacute intoxication with arsenic in a 30 years old woman. In addition to the classical peripheral neuropathy, we observed impairment of the superior neurological functions which improved together with the neuropathy. These malfunctions are rarely described in the literature although arsenic seems to cross the blood-brain barrier easily. There is no other explanation, and we believe arsenic to be responsible for these disturbances. We suggest systematic testing of the superior neurological functions in cases of arsenic intoxication.
