OBJECTIVE: The purpose of this study is to analyze the distribution of plantar pressure in six balletpositions and to compare those between the skilled and unskilled ballet dancers. METHODS: Thirty eight feet of healthy ballerina were evaluated by EMED-SF (Novel GMBH Inc. Ger.) system to analyze six positions of ballet. At each position, we estimated the static and dynamic positions. The forefoot was divided into 6 different zones on the basis of head of metatarsal bones. The degree of discipline was assessed by 3 expert ballerina. RESULTS: In each position, there were significant peak pressure distribution areas. In the skilled ballerina, there was less difference in peak pressure between the static and dynamic positions in comparision with the unskilled ballerina. In the skilled ballerina, more forces are distributed to M6 area in releve position and to M3 and M6 areas in turnout positions. CONCLUSION: Six basic ballet positions could be analyzed by plantar pressure measurement. There were some differences in the distribution of planter pressure in some ballet positions between the skilled and unskilled ballet dancers.

Thrombotic thrombocytopenic purpura (TTP) and the related hemolytic uremic syndrome (HUS) are disorders characterized by thrombocytopenia, microangiopathic hemolytic anemia, a variable degree of impairment of renal function and fluctuating neurological symptoms, which are thought to be due to platelet activation and subsequent formation of thrombi in the microcirculation. The fact that there was no clear-cut clinical and laboratory features that differentiate HUS from TTP has lead to view these two syndromes as a clinical continuum. Microvascular thrombosis is the typical lesion and closely related with endothelial injury and platelet activation. Pathologic alterations of the brain parenchyma are mainly manifested by small multiple infarcts. Numerous cases of CNS complications of these syndromes have been evaluated by using CT, but few reports have mentioned the MR findings. We experienced a case of TTP-HUS that had clinical features of cortical blindness and the brain lesion was confirmed by MRI showing cerebral infarct at the occipital area but it was reversible course. So we report this case with a brief review of literature.

We report a case of lipoid pneumo nia in a 57-year-old man who had a history of ingestion of green perilla oil and residual neurologic deficit of cerebral infarction with right hemiparesis. Lipoid pneumonia was diagnosed by bronchoalveolar lavage.
