Twitch transdiaphragmatic pressure (Tw Pdi) measured with magnetic stimulation of the phrenic nerve is used to follow up patients and to assess the effect of clinical treatments on diaphragm function. However the reproducibility of Tw Pdi on different occasions has been little studied. We investigated 32 normal subjects, measuring Tw Pdi elicited by bilateral magnetic stimulation of the phrenic nerves on two to 14 occasions. Sniff transdiaphragmatic pressure (sniff Pdi) was also measured. The mean value of Tw Pdi and sniff Pdi were 28+/-5 and 134+/-24 cm H(2)O, respectively. The within subjects coefficient of variation was 11% for both Tw Pdi and sniff Pdi. We conclude that there is a variability of Tw Pdi and the variability of Tw Pdi is the same as that of sniff Pdi.
We report two cases, of 48- and 53-year-old women, with huge intrathoracic extrapulmonary tumors which originated from the diaphragm. In these cases the totally resected tumors were examined histologically and immunohistochemically, and based on these studies benign localized solitary fibrous tumors originating from the diaphragmatic pleura were diagnosed. We observed no recurrence in the long-term follow-up, which was necessary for these cases due to the tumors' unpredictable clinical behavior even when they were thought to be benign histologically. Because of the huge sizes of these tumors, originating from the diaphragmatic pleura with pedicles, and benign clinical outcome correlating with the histological examination, these cases are thought to be worthy of interest.
Extraskeletal osteosarcoma is a rare malignancy that has not been previously reported to arise from the diaphragm. We describe the case of a 47-year-old woman who had a large thoracic mass found at operation to be an extraskeletal osteosarcoma arising from the diaphragm. The tumor was completely resected en bloc with a margin of surrounding diaphragm, which necessitated a diaphragmatic reconstruction. The literature concerning this rare tumor is reviewed.
