In order to evaluate the value of vertebral angiography in assessment of hemifacial spasm, we reviewed retrospectively the vertebral angiography of 28 patients(30 cases) with surgically proved hemifacial spasm but normal CT scans of posterior fossa. There were 9 males and 19 females. Angiography revealed vascular focus of hemifacial spasm located at anterior inferior cerebellar artery, posterior inferior cerebellar artery, and vertebral artery in 19, 9, and 2 cases respectively. Right side was involved in 20 cases. All involved vessels were elongated, tortuous, and dilated. In conclusion, vertebral angiography was valuable in evaluating hemifacial spasm of vascular origin in the posterior fossa.

Melorheostosis is a rare disease entity of bone with an etiology and pathogenesis. It cause pain and stiffness in an affected limb, and dense bone formation along the side of bone resembles the flow of candle dripping. Two cases of the disease involving left hand and wrist, and right lower leg are reported with the review of literature.

A sepsis or multiple organ dysfunction occurs frequently in the intensive care unit and causes a significant number of mortality and morbidity. Somtimes polyneuropathy of varying severity occurs in association with a sepsis or critical illness. Since the clinical evaluation is often difficult, electrophysiologic studies are employed to reveal a definitive evidence for polyneuropathy. The purpose of this study was to investigate the frequency of polyneuropathy and to determine the electrophysiologic features of critically ill patients. The subjects were 23 patients between ages of 42 and 72 with a sepsis or systemic inflammatory response syndrome combinded with the multiple organ failure. The results revealed reductions in the amplitude of compound motor action potential and sensory nerve action potential, as the most marked abnormality. Needle EMG revealed the signs of denervation of limb muscles. Approximately 65.3% of adult patient with sepsis or multiple organ dysfunction has an axonal polyneuropathy. We suspect that the axonal polyneuropathy is related to the severity of multiple organ dysfunction.

OBJECTIVE: The study was performed to evaluate whether thallium reinjection (RI) distinguishes viable from nonviable myocardium among myocardial segments which showed persistent perfusion defect (PD) in patients with acute myocardial infarction (AMI). MATERIALS AND METHODS: We studied 22 patients underwent PTCA after AMI. SPECT was performed in all patients using dipyridamole stress- 4 hour redistribution (RD) followed by 24 hour RI protocols. Dysfunctional segs were classified into 5 groups: 1) normal, 2) reversible, 3) mild to moderate PD, 4) severe PD and 5) reverse redistribution (RR). All patients underwent follow up echocardiography after 4 months to assess regional wall motion (WM) improvement such as a criteria of viable myocardium. RESULTS: A total of 127 segs with abnormal WM was analyzed. Of 74 segs with PD, 17 (23%) showed enhanced uptake after 24 hour RI. Five of 17 segs (29%) with PD that responded to RI with enhanced thallium uptake showed WM improvement. WM improvement were seen in the 24 of 57 segs (42%) not responding to RI. All four segs (100%) with RR that responded to RI showed improvement. WM improvement were not seen in the 5 of 8 segs (71%) with RR not responding to thallium RI. Eleven (73%) of 15 segs with mild-moderate PD after RI showed improvement, but 33% of segs with severe PD after RI did not showed improvement. Segs with mild-moderate PD after RI and fill in after RI showed improvement in comparison to segs with severe PD after RI(p<0.05). CONCLUSIONS: These data indicate that because only small proportion of PD showed further perfusion improvement after RI and predictive value by the uptake after RI was low, there was limited role of RI after myocardial infarction. Usefulness of RI could be found in segs showing RR responding to RI in AMI reflects viable myocardium.

Double primary cancer is defined as the case of primary malignant tumors in one person, which must be arisen in different sites and have a different histologic appearances in each other. The number of reported cases of multiple primary malignant tumors has increased in recent years, because of more developed diagnostic procedure and long survival of cancer patients, We have experienced 4 cases of double primary malignant tumors which were stomach cancer with colon, bronchus and esophagus cancer, and report these cases with review of literatures.
