Whose Stress is Making Me Sick? Network-stress and Emotional Distress in African-American Women

Research on stress-related health outcomes in African-American women often neglects “network-stress”: stress related to events that occur to family, friends, or loved ones. Data from the African-American Women's Well-Being Study were analyzed to examine self-stress and network-stress for occurrence, perceived stressfulness, and association with symptoms of psychological distress. Women reported a higher number of network-stress events compared with self-stress events. Occurrences of network-stress were perceived as undesirable and bothersome as self-stress. Both types of stress were significantly associated with psychological distress symptoms. Including network-stress may provide a more complete picture of the stress experiences of African-American women.

Comparing Operative Exposures of the Le Fort I Osteotomy and the Expanded Endoscopic Endonasal Approach to the Clivus

Objectives We compare surgical exposures to the clivus by Le Fort I osteotomy (LFO) and the expanded endoscopic endonasal approach (EEEA). Methods Ten cadaveric specimens were imaged with 1.25-mm computed tomography. After stereotactic navigation, EEEA was performed followed by LFO. Clival measurements included lateral and vertical limits to the midline lower extent of exposure (t test). Results For EEFA and LFO, respectively, maximal lateral exposure in millimeters (mean ± standard deviation) was 24.5 ± 3.7 and 24.5 ±  − 3.8 (p = 0.99) at the opticocarotid recess (OCR) and 25.1 ±  − 4.1 and 24.1 ±  − 3.0 (p = 0.53) at the foramen lacerum level; lateral reach at the hypoglossal canals was 39.0 ±  − 5.88 and 56.1 ±   − 5.3 (p = 0.0004); and vertical extension was 56.0 ±  − 4.1 and 56.3 ±  − 3.4 (p = 0.78). Conclusions For clival exposures, LFO and EEEA were similar craniocaudally and laterally at the levels of the OCR and foramen lacerum. LFO achieved greater exposure at the level of the hypoglossal canal.     

Localized orthodontic space closure for unilateral aplasia of lower second premolars

The present study aimed to determine whether routine orthodontic space closure can be successfully achieved in patients with unilateral aplasia of the lower second premolars without extracting contralateral or opposing teeth. The dental records and lateral cephalograms of 17 consecutively treated subjects (11 females, 6 males) aged between 14.8 and 19.3 years at the end of active treatment (mean 16.1 years) were analysed. The spaces were closed by 'push-and-pull' mechanics (PPM). Pre- and post-treatment data were compared using a Student's t-test. At the end of active treatment, all parameters (ANB, SNA, SNB, ML/NL, U1-NA, L1-NB, overbite and overjet, upper and lower midline, upper and lower space balance) presented mean values close to accepted norms with satisfactory standard deviations (SDs). Five indicators of success changed significantly: (1) Space closure in the aplastic region was achieved. (2) On the aplastic side, a mean mesial molar relationship of 1.12 (SD 0.18) cusp width (cw) was achieved. The mean alteration from pre- to post-treatment was 1.53 cw (SD 0.29, P 相似文献   

The first invention patents in general anaesthesia

Dra, Zimmer describes in this work the evolution of general anaesthesia for surgeries, quoting the recorded invention patents, since the 1st one performed in France - an ether anaesthesia - in 1846, 2 years after Wells had used nitrous oxide as gas for a surgery (december 1844).     

Change in caries prevalence after implementation of a fluoride varnish program

Objective : In 1996 the caries prevalence of schoolchildren living in Neukölln, a district of Berlin, Germany, was higher than the mean of total Berlin. Hence, a special preventive program including the application of fluoride varnish was initiated. All 49 primary schools of the district joined the project. The aim of the present study was to evaluate in a cross‐sectional study whether the preventive program resulted in a reduced caries prevalence. Methods : The complete program included oral health education as well as the application of a highly concentrated fluoride varnish (Duraphat®). All children whose parents' consent was given could receive fluoride varnish twice a year. All children were examined once a year by four calibrated dentists. The baseline examination was conducted in 1995–96, the final examination in 1999–2000 (1995–96: n= 7,748; 1996–97: n= 15,673; 1997–98: n= 19,362; 1998–99: n= 19,822; 1999–2000: n= 17,984). Results : A total of 80,589 dental records were used for data analysis. A decline of DMFT‐values was observed in all age groups and school years. The major improvement was found in school year 1999–2000, when the program had been established for four years. Conclusion : The described program may be an effective public health measure for 6‐ to 12‐year‐old children with high caries prevalence.     

The early international dental congresses

The importance of the dissemination of scientific and clinical advances brought about by the early international dental congresses cannot be underestimated. The congresses in 1889, 1893, 1900 and 1909 set the pattern for discussion and association for the rest of the twentieth and, now, the beginning of the twenty-first century.
