Parkinsonism is a very rare complication of phenytoin. The authors experienced a 71-year-old man who presented progressive cognitive decline, postural tremor, bradykinesia and gait disturbance. Laboratory test and brain imaging revealed no abnormality that commonly causes parkinsonism. The only abnormal finding was elevation of serum phenytoin above the therapeutic level. The patient showed marked improvement of symptoms by reduction of phenytoin dosage. Here we report a case of phenytoin induced parkinsonism.

Changes in the individual symptomatology were analyzed on twenty-nine patients with Parkinson's disease who underwent thirty-five stereotaxic thalamotomies to evaluate the influence of each symptom on the surgical results. The thalamotomy could obviously improve and prevent progression of tremor and rigidity but not bradykinesia and axial symptoms. Long-term follow-up wtudy with statistical analysis suggested that progressive worsening after surgery was due not to recurrence of tremor and rigidity but aggravation of bradykinesia and axial symptoms in the natural course of the disease. We believe that timely surgical treatment should be encouraged in patients presenting symptoms of tremor and rigidity.

Whilst rare, the acute development of involuntary movements with characteristic lesions of the bilateral basal ganglia in a diabetic uremic patient is a well-demarcated clinical syndrome. Most patients with this syndrome present with either parkinsonism or chorea; however, concurrent chorea with bradykinesia or parkinsonism is rarely reported. We report herein two diabetic uremic patients who developed acute chorea and bradykinesia with characteristic MR images.

Stereotactic thalamotomy has traditionally provided good relief of tremor for patients with intractable tremor dominant in Parkinson's disease. However bradykinesia, dyskinesia and rigidity are less reliably treated with this technique. Although posteroventral pallidotomy(PVP) can alleviate dyskinesias appendicular bradykinesia and rigidity, tremor may not be completely ameliorated. Between January 1993 and May 1997, the authors performed posteroventral pallidotomy(PVP) on 69 patients with Parkinson's disease who had bradikinesia, rigidity, drug induced dyskinesia and tremor. Of these patients who had only PVPs 17(25%) patients had severe tremor, 20(29%) patients moderate tremor and 32(46 %) patients mild or no tremor after the surgery. We have combined ventrolateral thalamotomy(VLT ) and PVP in 37 patients with moderate to severe tremor. Of the 37 patients, who had both PVP and VLT, 27(73%) patients showed good improvement, and fair improve-ment in 10(27%). Except for 6 cases with transient dysarthria we did not encounter any other operative complications from the ipsilateral combined PVP and VLT. The combination of the two procedures appear to provide excellent relief for the majority of symptoms in patients suffering from advanced Parkinsons disease with rigidity bradykinesia, dyskinesia and tremor.

We describe a case of Takotsubo cardiomyopathy in an elderly woman after status epilepticus. In an emergency echocardiography, not only left ventricular apical ballooning but also right ventricular apical hypokinesia was observed. After a medical management, the patient's condition was improved and a follow-up echocardiography showed substantial recovery of left and right ventricular apical ballooning.

The purpose of this study was to investigate the frequency of depression and the relationships between various clinical features and depression in the patients with idiopathic parkinsonism. We included 113 patients of idiopathic parkinsonism who had any three of resting tremor, rigidity, bradykinesia, impaired postural reflexes or any one of the first three displaying asymmetry without definite brain lesion on brain imaging studies or metabolic derangement. We used Beck depression inventory, and the results were compared with those of 70 normal controls. The following results were obtained: 1.The patients with idiopathic parkinsonism had more severe depression than normal controls. If we@ consider the cut-point scores for depression as more than 21points of Beck depression inventory scores, the frequency of depression in idiopathic parkinsonism was 44. 1%. 2.The scores of the BDI questionare representing somatic symptoms were increased in the patient group, whether they had mild or severe parkinsonian deficits. The patients who had more severe parkinsonian deficits had higher scores. However, those representing mood and self-reproach symptoms were increased only in the late stage of idiopathic parkinsonism. 3.The severe motor symptoms, particularly bradykinesia and rigidity, poor responsiveness to L-dopa treatment, longer the duration of disease, were the factors correlated with severe depression. However the current age, age of onset, whether treated or untreated, and whether sy7rnptonis affected predominantly right or left side of the body, were not correlated with the severity of depression. On the basis of the results, when we regard no tremorous symption and the poor responsiveness to L-dopa treatment as the clinical features of idiopahtic parkinsonism, we suspect the tendency that the patients with idiopathic parkinsonism may have more severe depression than those with idiopathic P-qrkinson's disease.

BACKGROUND: Cardiovascular MR has recently been reported that it can determine the viable myocardium. We investigated this study to determine the usefulness of cardiovascular MR in prediction of wall motion recovery after revascularization in acute myocardial infarction METHODS: Both cardiovascular MR with contrast enhancement and coronary angiogram were performed in 19 patients with acute myocardial infarction who treated with precutaneous intervention or thrombolytic therapy. Six months follow-up angiogram and MR study were also preformed. Thirty two matched segments model of the left ventricle were used to analysis the wall motion change and the grade of transmural extent of hyperenhancement (TEI). RESULTS: Among 628 segments, 177 segments showed wall motion abnormality. In group of segments showing hypokinesia (68 segments), the proportion of segments showing wall motion improvement was not different from that of the akinetic segments group (109 segments) (50% vs 41.3%, p=0.26). The proportion of segments showing wall motion improvement were 60.5% in group of TEI grade 0, 58.9% in TEI grade I, 51.2% in TEI grade III, 29.4% in TEI grade IV, 8% in TEI grade V. If the groups were divided into two according to cut-off value of TEI 50%, In the group of TEI less than 50%, 67 out of 118 segments (56.8%) showed wall motion improvement in contrast with 12 out of 59 segments (20.3%) in the group of TEI above 50% (p<0.001). The status of baseline wall motion abnormality (hypokinesia or akinesia) did not effect on wall motion improvement after revascularization. CONCLUSIONS: The baseline wall motion abnormality (hypokinesia or akinesia) did not predict the wall motion improvement. But, TEI grade was significant factor to predict the wall motion improvement.

A variety of toxins cause parkinsonism and the lesions are primarily in the pallidostriatum. It usually does not respond to levodopa. We experienced a patient whose parkinsonian features developed after accidental acetone ingestion. She had rigidity, bradykinesia, gait disturbance and her speech was sluggish. Brain MRI showed bilateral basal ganglionic lesions. She was treated with levodopa and her neurological symptoms improved. To our knowledge, there has not been any previous reports of acetone causing parkinsonism. Acetone may cause parkinsonism by damaging the basal ganglia.

PURPOSE: The aim of this study was to evaluate the cardiovascular manifestations and clinical course in patients with acute carbon monoxide poisoning. METHODS: A retrospective study was conducted over a 36 month period on consecutive patients who visited an emergency medical center and were diagnosed with acute carbon monoxide poisoning. A standardized data extraction protocol was performed on the selected patients. RESULTS: A total of 293 patients were selected during the study period. Cardiac manifestations were observed in 35.2% (n=103) of the patients: hypotension in 11 patients (3.8%), ECG abnormalities in 44 patients (15.0%) and cardiac enzyme abnormalities in 103 patients (35.2%). Echocardiography was performed on 56 patients with cardiac toxicity: 12 patients had abnormal results (5 patients with global hypokinesia and 7 patients with regional wall akinesia). Five patients died within 3 hours after ED admission, and the remaining patientswere discharged alive. At 3 months after discharge, none of these patients had died.The SOFA scores in the severe cardiac toxicity group and non-severe cardiac toxicity group at the time of arrival were 2.53+/-2.29 and 2.19+/-2.12, respectively (p=0.860). CONCLUSION: Cardiovascular manifestations occurafter acute CO poisoning at arateof 35.2%. Even those with severe cardiovascular toxicity recovered well within 10 days after admission. Therefore, the importance of cardiac toxicity after acute CO poisoning is not significant initself in the clinical course, and the short-term prognosis of cardiac toxicityis unlikely to be unfavorable in acute CO poisoning.
