Typical results of computer-olfactometry

After pulsed peripheral olfactory impulses it is possible, under suitable testing conditions, for specific sensory potentials to be read from the surface of the skull and, after repetitions, added up (olfactorially evoked cortical potentials). Typically, there developes a so-called twin-potential containing the equivalents of the electrical activites of the nervus trigeminus and the nervus olfactorius in two peaks of the cortex equivalents. In an objective manner, in other words without intentional or vegetative influence by the test person, it is possible by the weakening or lack of one or the other or both part-potentials to obtain information about the functioning of the olfactory sense. Typical examples will be presented.     

Encouraging results of split-liver transplantation

Two sisters affected with renal cell carcinoma (RCC) is an extremely rare finding, and may indicate a hereditary pattern or the presence of other predisposing factors. We describe here 2 sisters presenting with clear cell renal cell cancer. Examination for von Hippel-Lindau (VHL)-related features and tuberous sclerosis (M. Bourneville) was negative and both had a normal constitutional karyotype. Cytogenetic analysis of the tumor tissue of both patients showed a translocation involving chromosomes 3 and 5, resulting in loss of 3p sequences and gain of part of 5q. The 5q breakpoints were similar, but the breakpoints at 3p appeared to differ. Allelic imbalance analysis supported our observations. Microsatellite analysis revealed that both sisters inherited different chromosome 3 parental alleles. For chromosome 5, 3 different haplotypes could be deduced, but the chromosome 5 alleles overrepresented in the different tumor tissues were from different parental origin. The development of the 2 RCCs in these 2 sisters thus cannot be explained by the inheritance of a mutated VHL gene located at 3p25, nor by the inheritance of other gene defects at chromosomes 3p or 5q. Although the chance that 2 sisters develop sporadic RCC is very low, in the presented case it is probably coincidental or related to another genetic predisposition.     

Psychological results of reconstructed patients

The author attempts to present some points which seemed important to her or who impressed her at the occasion of a first psychological approach of 25 women having gone through a breast reconstruction after mastectomy for cancer. She mentions the sources of information about the reconstruction possibilities, which have urged the women to ask for reconstruction, the reactions of the partners and the possible changes on the sexual life, and the openings the reconstruction brought them from a personal and relational point of view.     

Long-term results of arthroscopic meniscectomy

A 13-year-old boy with a rare giant fusiform aneurysm at the horizontal portion of the middle cerebral artery (M1) presented with progressively severe throbbing headache. The aneurysm was reconstructed by tandem application of nine fenestrated clips and coating of the remnant of the aneurysm. However, he was readmitted 3 months later because of recurrent aneurysms at the proximal and distal M1 portions which had been coated. The aneurysms were trapped after rupture occurred during a second operation. Aneurysm trapping combined with superficial temporal artery-middle cerebral artery bypass surgery may be a better method to treat such aneurysms.

实验室测量结果的评价

为了正确、合理评价分析方法和测试数据,依据分析测试的测量参数、分析方法的精密度参数（重复性限和再现性限）以及实验室间共同试验数据,用数理统计方法论证测量结果的精密度和正确度,给出了实验室测量结果精密度和正确度检验的方法。试验数据的统计结果可作为分析方法的选择、分析测试数据精度和正确度的评定、实验室内和实验室间测试数据的比对、标准物质定值分析数据评定的判据。所提出的检验方法建立在数理统计和共同试验数据的基础上,有很好的可靠性和实用性。     

Late results of treatment of megaesophagus

Heller's operation remains the best operation but pneumatic dilatation, which has replaced other methods, gives equivalent results. Our report may be completed by better assessment of the physiopathology, new methods of exploration and more precise knowledge of the complications and failures of myotomy. Finally, the chapter, cancer and megaoesophagus, is the most important to be added.     

Choledochotomy and its results

Of 21 patient to whom after choledochotomy the external drainage of common bile duct was conducted, the suture insufficiency have occurred in 3, 2 patients died. After choledochoduodenostomy conduction the suture insufficiency was observed in 3 of 17 patients, 2 patients died. After papilloshincteroplasty conduction the complications were revealed in 5 of 23 patients, 3 patients died. Of 4 patients, in whom the twin internal drainage was conducted, 3 died.     

Functional results of percutaneous laser discectomy

The purpose of the study was to evaluate laser disc decompression with the KTP 532 laser, used in conjunction with a percutaneous technique, in contained, small to moderately sized lumbar disc herniation. Sixty-three patients who had a contained herniated nucleus pulposus (HNP) and underwent percutaneous laser disc decompression were prospectively studied. Sixty-one were available for follow-up. Access to the disc space was attained with an 18-gauge probe, followed by dilating cannulas guided with an image intensifier. Discography was not performed. The power was set at 10 W, and laser pulses were delivered for 0.2 seconds, with an interval of 0.5 seconds. A total of 1250 J was delivered to the disc space. The average follow-up was 31.75 months (range, 20 to 45 months). Overall, 44 patients (72%) achieved relief of radicular pain, and 33 patients (54%) achieved relief of low back pain. Thirty-six of 61 patients (59%) returned to work by postoperative week 4. Fourteen patients failed treatment, experiencing persistent symptoms (with scores on the Andrews and Lavyne rating scale of < or = 3). In this study group, optimal results were obtained when symptoms were treated within 1 year of presentation. Results from a historical control group are provided for comparison.
