Axel Zöllner Urs Belser On behalf of Working Group 《Clinical oral implants research》2007,18(S3):114-116
Abstract: In order to evaluate the level of evidence of factors influencing the survival of reconstructions, systematic reviews of the relevant literature were prepared by a group of rapporteurs. The review papers were circulated to the members of the group before the conference and formed the basis for group and panel discussions. Subsequently, modifications were added to the review papers, and suggestions for consensus statements concerning the following topics were prepared and again critically reviewed in the group and in the plenum: Impact of (i) periodontal disease on the survival of tooth-supported reconstructions, (ii) post-surgical factors as supportive therapy on the survival of implant supported reconstructions, (iii) technical and/or biological complications on the survival of different types of reconstructions, (iiii) material choice for reconstructions on the survival of single crowns and fixed dental prostheses. 相似文献

Unique variant of partial anomalous pulmonary venous connection with intact atrial septum 总被引:1,自引:0,他引:1
Summary Partial anomalous pulmonary venous connections (PAPVCs) are rare in association with an intact atrial septum. However, the diagnosis should be considered in patients with otherwise unexplained findings of left-to-right shunt and right heart enlargement. An unusual variant is presented, which we considered unsuitable for operative repair, based on findings at catheterization. Developmental, hemodynamic, and surgical considerations are discussed. 相似文献

Two experiments investigated the effects of haloperidol (0.1 mg/kg) on the partial reinforcement extinction effect (PREE). In experiment 1 two groups of rats were trained to run in a straight alley using six trials/day with an intertrial interval (ITI) of 5–8 min. The continuously reinforced (CRF) group received food reward on every trial. The partially reinforced (PRF) group was rewarded on a quasi-random 50% schedule. All animals were then tested in extinction. Haloperidol was administered in a 2 × 2 design, i.e., drug-no drug in acquisition and drug-no drug in extinction. In experiment 2 two groups of rats were trained to press a lever in an operant chamber using a discrete trial procedure of ten trials/day with an ITI of 60 s. The CRF group was rewarded on each trial and the PRF group was rewarded on a quasi-random 50% schedule. Haloperidol was administered for 22 days prior to the start of the PREE procedure as well as throughout acquisition and extinction. The PREE, i.e., increased resistance to extinction of PRF as compared to CRF animals, was obtained in both experiments in all drug conditions. In both experiments haloperidol increased the rate of extinction. Experiment 1 revealed that this effect was entirely dur to the administration of the drug in extinction, independently of the drug condition in acquisition. In contrast to previous results in a one trial/day procedure, the administration of haloperidol to CRF animals did not increase resistance to extinction, failing to support the notion that neuroleptics attenuate the rewarding properties of reinforcement. 相似文献

The influence of partial gastrectomy on biochemical parameters of bone metabolism and bone density 总被引:2,自引:0,他引:2

Summary Since it has been suggested that gastric resections are followed by changes in bone metabolism, the aim of our study was to determine the biochemical parameters of bone metabolism and radial and lumbar bone density in 15 male ulcus patients treated by partial gastrectomy (Billroth II). Comparing the data with those of a corresponding control group, the lumbar bone density measured by quantitative computed tomography was statistically significantly lower (P < 0.04) in the patient group, whereas the peripheral bone mass of the distal part of the nondominant forearm measured by single-photon absorptiometry showed no statistically significant difference. In addition, a marked increase in alkaline phosphatase (P < 0.002) and urinary excretion of hydroxyproline (P < 0.003) was found in the gastrectomy group, whereas the 25-hydroxy-vitamin D levels were found to be significantly decreased (P < 0.04). Osteocalcin, a biochemical marker for osteoblast activity, and the carboxy-terminal propeptide of type I procollagen (PICP), a marker of collagen formation, were slightly but not significantly higher in gastrectomy-treated patients. The serum parathyroid hormone levels were similar in both groups. As none of the patients had any radiologic evidence of osteopenia, the changes in biochemical parameters of bone metabolism and bone mass in patients who had undergone partial gastrectomy could be a marker of latent bone loss.Abbreviations DPA/SPA

Can we predict the outcome of a partial rupture of the anterior cruciate ligament?
A prospective study of 43 cases 总被引:2,自引:0,他引:2
D. Fritschy Andreas Panoussopoulos Richard Wallensten Robin Peter 《Knee surgery, sports traumatology, arthroscopy》1997,5(1):2-5
The concept of partial rupture of the anterior cruciate ligament (ACL) has been confirmed by arthroscopic examination and
palpation. We present a prospective study of 43 patients who were diagnosed arthroscopically as suffering from a partial rupture
of the ACL by the same surgeon. The patients followed a rehabilitation protocol and were examined by an independant observer
after 5 years. Twenty-five patients had a stable knee, whereas 18 eventually suffered a complete ACL rupture. ACL partial
rupture is easily recognizable with arthroscopy, but the quantity and state of the still intact fibres is difficult to assess.
