Influenza vaccination can trigger various adverse reactions, and thrombocytopenia is also rarely reported. Although patients with mild thrombocytopenia are sometimes asymptomatic, severe thrombocytopenia can cause severe bleeding. We herein report a rare case of severe thrombocytopenia that occurred within one day of influenza vaccination and diffuse alveolar hemorrhage (DAH) leading to acute respiratory failure. The patient was treated with glucocorticoid pulse therapy, intravenous immunoglobulin, and temporary mechanical ventilation, and eventually he made a full recovery. Vaccine-related thrombocytopenia and DAH should be considered adverse reactions, even if they develop very soon after vaccination.

The influence of maternal vitamin B12 malnutrition on testicular development of offspring was examined using soy protein-based B12-deficient diets with or without 0.5% DL-methionine supplementation. Dams were fed the B12-deficient diet throughout gestation and lactation, whereas dams in a control group were fed a control diet which contained cyanocobalamin in the B12-deficient diet without methionine. Offspring born to dams fed the B12-deficient diet without methionine showed poor testicular development, e.g. decreased numbers of seminiferous tubules containing healthy spermatocytes and a high ratio of apoptotic cells per all germ cells. The abnormality was rarely observed in the group fed the B12-deficient diet with methionine. It was likely that the testicular abnormality of offspring was caused by B12-deficiency post partum and was prevented by the methionine supplementation. These observations suggested that maternal B12 nutritional status during the pre-weaning period is quite important for spermatogenesis of male offspring and that the requirement of B12 for testicular development is to produce active B12-dependent methionine synthase.

There are many articles about the conflicts or dilemmas with which teachers confront. In these studies, conflicts are treated from two aspects: the one is structural conflicts which include status conflict or role conflict (Ambivalence), and the other is conflicts on the level of action (Dilemma). They treat dilemmas, however, just as the restatement of ambivalences, that is, they do not examine the particular features of dilemmas. This paper focuses on the dilemma itself with which teachers confront in the face-to-face situation. Such dilemma should be caused when teachers find out no response from their students (situational dilemma). When one tries to resolve a dilemma in one situation, it might bring out another new dilemma. In some cases, this causes a vicious cycle. There are very few sociological studies on the features of such a vicious cycle and the mechanism by which it is created. This paper analyzes, using the concepts of "situational dilemma" and "strategy," the problematic face-to-face situation and the vicious cycle which comes out in the effort of the resolution of dilemma. Firstly, I describe the features of the dilemma with which teachers confront in the interaction with their students (situational dilemma). Secondly, I explain the significance of strategies teachers use as a means of avoiding such a dilemma. By using the concepts of "situational dilemma" and "strategy" as the core of the study, we shall be able to make clear the process of the reproduction of teachers' alienated situation. Furthermore, it should provide a new perspective for the studies of staffroom culture, occupational socialization and deviance of teachers.
