1例27孕周胎儿的中毒性表皮坏死松解症

世界核心医学期刊文摘（皮肤病学分册） 2005年第6期1卷 50-51页

Toxic epidermal necrolysis (TEN) is very rare in the newborn period. So far, three cases of TEN in newborns have been reported worldwide. We report a premature infant of 27 weeks’ gestational age with TEN at 4 weeks of age. Sepsis treated by an antibiotic combination regimen preceding the TENwas a common feature of all four cases. In our patient, coagulase-negative staphylococci could be identified by blood culture, whereas the previously reported patients suffered from klebsiella pneumoniae sepsis or Escherichia coli sepsis. Possibly, the uniform association with septic infection in the cases of TEN in the neonatal period might hint at a causal association, thus differentiating it from TEN in older children or adults.

软X线治疗皮肤基底细胞癌和鳞状细胞癌

Background: We have used a schedule for soft x-ray therapy of epithelial malignancies that takes into account the clinically diagnosed tumor involution under treatment. Objective: We sought to evaluate the effectiveness of this schedule in terms of cure rate and late ulcerations. Methods: Patients with 1267 consecutively irradiated (1988- 1992) basal cell and squamous cell carcinomas were followed up (average 77months). Results: The recurrence rate (5.1% ) was related to tumor size and thickness and to the time-dose-fractionation factor. The frequency of ulcerations (6.3% ) depended on field size, hardness of the x-rays, and in smaller fields (diameter up to 4 cm) on total dose, and time-dose-fractionation factor. Of all ulcerations, 82.5 % could be conservatively cured. Limitations: We have no evidence that our radiation schedule is superior to those published by other authors. Conclusion: These results verify the

Basal cell carcinoma (BCC) is the most common tumor in humans and is defined as a slow-growing, locally invasive, epithelial skin tumor which rarely metast *** first line treatment is surgical excisionwith histologic examination of the tumormargins, but numerous alternative therapies are available. A 75- ya r old patient with the most destructive form of BCC, ulcusterebrans, involving the scalp and invading the frontal bone. We discuss the problems and therapeu tic limitations for this unusual BCC variant.

The vacuum heat treatment with overpressure gas quenching is more and more accepted due to considerable advantages compared to the traditional oil and salt bath processes. Continuous further developments and new concepts like multi-directional cooling systems, a separate quenching chamber and "sub zero" systems lead towards an oxidation free and low distortion vacuum heat treatment for a broad range of parts and materials. Short and energy saving processes guarantee a high economic efficiency and environmental compatibility. The "sub zero" system which is integrated into the standard vacuum furnace achieves a heat treatment result with a high conversion of retained austenite in fully automatic hardening and tempering processes.

The Compact Linear Collider （CLIC） is a future e＋e linear collider. The CLIC study concentrated on a design of center-of-mass energy of 3 TeV and demonstrated the feasibility of the technology. However, the physics also demands lower energy collision. To satisfy this, CLIC can be built in stages. The actual stages will depend on LHC results. Some specific scenarios of staged constructions have been shown in CLIC Concept Design Report （CDR）. In this paper, we concentrate on the main linac lattice design for Ecm=l TeV CLIC aiming to upgrade from E~.,=500 GeV CLIC and then to Ecru=3 TeV one. This main linac accelerates the electron or positron beam froth 9 GeV to 500 GeV. A primary lattice design based on the 3 TeV CLIC main linac design and its optimization based on the beam dynamics study will be presented. As we use the same design principles as 3TeV CLIC main linac, this optimization is basically identical to the 3 TeV one. All the simulations results are obtained using the tracking code PLACET.

The optimal control of complex thermal energy systems is a challenge due to their dynamic behavior andconstantly changing boundary conditions. To maximize the energy efficiency of such a dynamic system, optimaltrajectories for the controlled variables are needed. Extensive system knowledge is required to model the systemaccurately enough to be able to compute optimal trajectories. The high computational cost of computingoptimal control solutions with traditional approaches, especially with changing boundary conditions, oftenmakes this approach unusable for applications with limited computational power, such as real-time applicationson electronic control units (ECUs). This study investigates a possible solution to this challenge using a simplifiedexample system. Optimal control solutions for different boundary and initial conditions are generated forthe selected solar thermal system using a direct multiple shooting algorithm. Based on Bellman’s optimalityprinciple, the generated solutions are transformed into a data set of optimal state–action pairs. On this basis,different types of neural networks are trained, specifically a feed-forward, a recurrent, and a radial basisfunction network. Thus, data generation and training can be performed offline, and the required online computations are significantly reduced since the evaluation of a trained neural network requires comparatively lowcentral processing unit (CPU) power. The trained neural network controllers are tested for their ability to outputnear-optimal control actions based on the current system state. The feed-forward and recurrent neural networksshow promising initial results in this regard. Open questions and the need for improvements are discussed.

A 36- year-old man presented with a giant congenital melanocytic n evus and multiple disseminated melanocytic nevi. After he had developed neurological sym ptoms (grand mal seizures), a cerebral metastasis of a malignant melanoma withou t a primary melanoma was found. The patient was diagnosed as having a neurocutan eous melanosis with a cerebral metastasis. In spite of a variety of therapeutic attempts (surgery, radiation therapy and chemotherapy) he followed a rapidly pro gressive, lethal course with increased intracranial pressure, hydrocephalus and spinal metastases.

Fruit and leaf shoot of litchi （Litchi chinensis） infestation by naturally occurring populations of the fruit bprer, Conopomorpha sinensis larvae and C. sinensis parasitization rates were determined in litchi orchards in northern Thailand at high （ca. 1 400 m ASL） and low （ca. 800 m ASL） elevations with different, non-overlapping fruiting seasons. In addition, spray applications of Bacillus thuringiensis var. aizawai, the natural compound spinosad and the chemical pesticide imidacloprid were conducted in the field to test the effects of these agents on C. sinensis fruit infestation rate. Fruit infestation rate and fruit growth, studied in a low elevation orchard, were sigmoidal and showed a highly significant positive correlation （P ≤ 0.01）. Leaf shoot infestation rate in the low elevation orchard decreased in the course of the fruiting season （March until May）, but increased in the high elevation orchard, where no fruits were present within the same period of time. Together, these results indicate that females of C. sinensis clearly prefer fruits over shoots for oviposition. If no fruits are available, which was the case in the high elevation orchard during that time, they are constrained to lay their eggs on shoots. The parasitization rate of C. sinensis larvae in untreated fruits was 54.3%. The parasitoid species were Chelonus chailini （90.8%） and Phanerotoma sp. （9.2%）. In the leaf shoots, C. sinensis was found to be parasitized by Phanerotoma sp. and Apanteles briareus. The applications of the different active agents had no significant effect on C. sinensis fruit infestation compared to the untreated control. Besides the cryptic life of the larvae, this is most probably explained by the fact that C. sinensis has several generations during the fruiting season. Because of the high parasitization rates recorded, an alternative and more effective control measure than the application of pesticides might be the augmentative release of parasitoids.
