Dimensional alterations of the gingiva related to changes of facial/lingual tooth position in permanent anterior teeth of children

Abstract Maxillary and mandibular anterior permanent teeth in 38 children aged 7–12 years were examined 2 × with an interval of 2 years to determine whether spontaneous facial/lingual tooth position changes were related to alterations of the widths of keratinized and attached gingiva and the clinical crown height. Measurements included dental plaque, gingival inflammation, probing depth, and width of keratinized and attached gingiva. In addition, study casts from the baseline and 2-year examinations were used to measure clinical crown height and tooth position. The results showed that significant alterations in the widths of the keratinized and attached gingiva took place when the teeth changed positions in facial or lingual directions. The changes in gingival widths could to some extent be coupled to changes in clinical crown height. In teeth moving lingually, the gingival widths increased and the clinical crown height decreased. In teeth moving facially, the gingival widths decreased, and the facial gingiva sometimes receded. These gingival alterations call for examination of the facial gingiva as part of the monitoring of the development of the permanent dentition.     

Therapeutic traditions in type 2 diabetes — are they changing?

The utilisation of antidiabetic drugs reflects both the prevalence of diabetes and the different therapeutic traditions of physicians. A questionnaire survey to study attitudes to the use of oral antidiabetic drugs amongst physicians and possible changes in treatment habits was carried out in a representative sample of Finnish physicians (n=454) in 1992 and the results were compared with those of a similar survey carried out in 1985, and with drug utilisation statistics.The mean fasting blood glucose level at which a physician would start pharmacological treatment was 8.7 mmol·l^–1, which was significantly lower than in the 1985 survey. The responses to various case histories suggested a more active approach to pharmacological treatment compared to the 1985 survey. Insulin treatment especially seems to have gained in popularity. This change in attitude was paralled by an increase in the consumption of antidiabetic drugs in Finland during the observation period. The increase in use of oral drugs was steeper in Finland than in Norway and Sweden.Whether this active approach will improve the metabolic control and prognosis of patients with Type 2 diabetes, remains to be demonstrated.     

Relative bioavailability of four controlled-release nifedipine products

Four controlled-release nifedipine products were investigated in two clinical studies. In study 1, 22 healthy male volunteers took part in an open, multiple-dose, randomized, crossover study to determine the relative bioavailablity of two 10 mg controlled-release nifedipine tablet (Adalat® Retard, Bayer), administered 12 hourly, and one 20 mg controlled-release nifedipine tablet (Adalat® Retard, Bayer) administered 12 hourly. In study 2, 24 healthy male volunteers took part in an open, multiple-dose, randomized, three-period, crossover study to determine the relative bioavailability of (i) two 30 mg nifedipine gastro-intestinal therapeutic system (GITS) tablets (Adalat® XL, Bayer) administered once daily; (ii) one 60 mg nifedipine GITS tablet (Adalat® XL, Bayer) administered once daily; and (iii) one 20 mg plus one 10 mg nifedipine controlled-release tablet (Adalat® Retard, Bayer), administered 12 hourly. In both studies detailed pharmacokinetic data, in particular with respect to the controlled-release characteristics of the different formulations, were collected. Results of both studies indicate that all nifedipine products investigated are bioequivalent with respect to the extent of absorption of nifedipine. The nifedipine GITS products (Adalat® XL) have better controlled-release properties than the Adalat® Retard product, and are suitable for once-a-day administration.     

十二烷氮酮氟尿嘧啶凝胶治疗疣及银屑病150例

443例(男225例,女218例;年龄36±14a)皮肤病患者,其中150例(扁平疣52例、寻常疣55例、银屑病43例)外用含1.8％十二烷氮(艹卓)酮的1％氟尿嘧啶(5-FU)凝胶作为治疗组,148例外用1％5-FU凝胶及145例外用2.5％5-FU霜作为2个对照组。经双盲对照临床试验,结果表明含1.8％十二烷氮(艹卓)酮的1％5-FU凝胶的疗效明显优于2个对照组(P<0.01及P<0.005)。证明氮(艹卓)酮对5-FU确有渗透促进作用。     

第二产程产妇自由体位分娩效果的研究
