A 53-year-old man complaining of vertigo initially consulted a nearby hospital. While undergoing a medical examination, which included abdominal ultrasonography and a CT scan, a dilatation of the pancreatic duct was found. The patient was then admitted to our hospital for a more thorough examination. Laboratory findings revealed an elevated elastase-1 level and a DM-pattern of 75 g-OGTT. ERP showed a localized constriction in the main pancreatic duct and diffuse dilatations of the distal main duct. A cytologic examination revealed no malignant cells in the pancreatic juice. Even so, though a carcinoma was not confirmed, a pancreaticoduodenectomy was performed, since a carcinoma of the pancreas head was suspected. A histological examination of the resected specimen uncovered a nonfunctioning islet cell carcinoma, 8 mm in diameter. This case was considered fortunate, in that an early stage pancreatic cancer, adjacent to the main duct, had been detected by imaging diagnoses.

Changing the interaural time difference (ITD) of continuous band noise applied to both ears causes a shift in the perceived lateralization of the noise and evokes the special potentials called "time-shift evoked potentials (TPEPs)". These potentials consist of a positive-negative-positive complex, like a slow vertical response (SVR). Each peak latency of this potential, however, was about 20 msec longer than in the SVR. Testing of 45 volunteers with normal hearing revealed that the feature of this response matched the hearing function test results of detecting lateral position of a sound image. Therefore it could be useful as an objective testing for the hearing function of sound latelization. The following were established as the conditions for use, in clinical practice: time difference between ears: 0.7 msec; sound intensity: 30 dB SL at 500-Hz band noise; stimulus interval: 3.0 sec.; and potential recording from Cz on the scalp. This response was tested in 29 cases of hearing disorders (14 cases of inner ear deafness, 2 cases of tinnitus without deafness, 6 cases of peripheral vertigo, 5 cases of intracranial disease, 1 case of functional hearing loss, 1 case of head trauma), and the results were compared with those of the directional hearing test, auditory brainstem response (ABR), and SVR, by using the chi-square test. The results of the directional hearing test and ABR were shown to be correlated with this ERP, and SVR was shown to be independent of it. Thus, it was concluded that this potential is useful as a clinical test. The significance of the conclusions is explained on the basis of Berjeik's theory.
