[The health status and bucco-dental pathology in the elderly]. / Starea de sanatate si patologia buco-dentara la vîrstnici.

By analysing in 2,769 patients the relation between bucco-dental pathology and age, it was noticed that the frequency of odontic affections decreases and that of chronic marginal periodontopathies increases with age. In the elderly, a tendency towards delaying the treatment of pulp inflammations and a very high percentage of extractions performed in the chronic marginal periodontopathies (81.8%) were noticed. The bucco-dental state of health was determined in 75 old-aged over 60 years, the ICORA and CPITN indices being used. Of these individuals, 93.3% presented various edentate forms, half without prosthetic appliance. Various degrees of pathological changes in the marginal periodontium were recorded in 92.3%, being more severe in women and individuals from rural areas.

[Bacteria detected in the duodenal aspirate of patients with biliary tract disorders]. / Consideratii asupra bacteriilor depistate în aspiratul duodenal al pacientilor cu suferinte ale cailor biliare.

In 614 patients with pains in the right hypochondrium the cyto-bacterioscopy and bile culture were performed. In 575 patients bile samples were obtained by sterile catheterization and in 39 patients by biliary tract puncture during surgical intervention. It resulted that for a reliable cyto-bacterioscopic examination and its agreement with bile culture results it is necessary to investigate only the samples with pH greater than or equal to 5 and during the first two hours after their collection. The isolated bacterial species can be considered to be etiologic agents of the biliary infection depending on the following parameters: significant quantitative threshold of minimum 10(5) colony forming units per milliliter, presence of inflammatory reaction and activity of the gastric acid barrier.
