Descending necrotizing mediastinitis(DNM) is one of the most lethal form of mediastinitis originating from an oropharyngeal infection. It requires an early and aggressive sugical treatment, but the operative approach and optimal form of mediastinal drainage remains controversial. We report a case of DNM in a 45-year-old male who underwent right cervicomediastinotomy to drain the deep neck space, upper mediastinum and anterior mediastinal drainage was accomplished through a subxiphoid approach. After this procedure, he steadily improved and was dischrged on hospital day 36. We report this case with a brief review of the literature.

In this paper, a new sensorless control based on an adaptive sliding mode observer is proposed for the interior permanent magnet synchronous motor(IPMSM) drives. With using voltage equation only, the adaptive sliding mode observer was investigated. The proposed adaptive sliding mode observer is applied to overcome the problem caused by using the dynamic equation. Furthermore, the Lyapunov theorem is used to prove the system stability included speed estimate and speed control. The effectiveness of the proposed algorithm is confirmed by the experiments.

Autophagy is the process of forming vesicle structure by response to nutritional deficiency or outside stress and then surrounding and decomposing cell organelles to make energy. Autophagy, which is activated by being given diverse stimuli of stress including exercise, plays an important role in generating and maintaining energy in diverse muscles as well as skeletal muscle. However, there are very few studies on the physiological mechanism to explain the effects of such autophagy on cardiac muscle both at home and abroad. Thus, this experiment was conducted through acute swimming exercise to learn what effect autophagy makes on cardiac muscle. For lab animal, 24 experimental rats were bred in groups of 6 mice (control + saline solution, control + colchicines, exercise + saline solution, exercise + colchicines) using plastic cages, with temperature of 24-25℃, 70-80% humidity and light control in 12-hour cycle for breeding room. The selected animals were supplied with pellet and sufficient water for the whole period of experiment. Before this exercise, all the subject mice were given training for adaptation for two days, 10 minutes for each, while at this exercise, 12 rats in exercise group were given exercise in the water of 35 to 36℃ in two divided sessions (1-hour swimming + 15-minute rest + 1-hour swimming). For colchicine and saline solution, three times of treatment in total were given including the two days right after adaption training and right after the main training. Samples of cardiac muscle were abstracted 24 hours after exercise while conducting Western blot by use of LC3 and p62 as antibodies to observe the change of cardiac muscle caused by autophagy. Group in treatment with colchicine showed a clearer difference in change compared to group in treatment with saline solution, while results were drawn among groups in treatment with colchicine. Compared to control group, change in LC3-II showed a significant difference for the whole group of ‘exercise + colchicine’ with a significant difference in Gel-2 and Gel-3, except Gel-1, for the analysis by gel. However, visible increase was also found in Gel-1. As to p62, compared to control group, the whole group of exercise + colchicine treatment showed significant difference. As with LC3-II, however, there was no significant difference found in Gel-1, but with significant difference in Gel-2 and Gel-3. Through this, it was found that acute swimming exercise makes significant effect on autophagy of cardiac muscle, meaning the effect of stimuli like exercise on cardiac muscle. Furthermore, supposing autophagy as apoptosis or energy source, it is considered possible to help in solving the problems of modern society by applying it to aging, sarcopenia, discontinuance in training, long-term exercise, etc.
