BACKGROUND: The relationship between the anterior site of acute myocardial infarction(MI) and occurrence of stroke has become a recent subject of much debate in the relevant literature. The object of this study was to examine the incidence of ischemic stroke during the hospitalization after an acute MI and to identify predictors of MI-related stroke. METHOD: We performed retrospective analysis of 452 patients with acute MI admitted to department of Neurology or Cardiology from January 1990 to August 1997. Patients with a stroke during hospitalization after acute MI were recruited for this study. RESULT: Thirteen cases were recorded. Seventy-seven percent (10/13) of the strokes occurred within 4 days after onset of MI. Multivariate analysis identified the following as independent predictors of stroke : History of hypertension(OR. 2.6: CI, 1.1 to 5.9), previous stroke(OR, 22.3: CI, 5.9 to 84.9) and congestive heart failure (CHF)(OR, 15.4: CI, 2.2-108.6). Transthoracic echocardiography(TTE) was performed in 349/452(77%) during hospitalization. The incidence of left ventricular thrombosis(LVT) in patients with anterior MI who received thrombolytic and anticoagulant therapy was not significantly different from that in patients with anterior MI who didn't(2.6% vs 6.1%, p=0.265). Stroke developed in only one of these patients with LVT. Thrombolytic and anticoagulant therapy were more frequently used in patients without stroke compared with stroke.(p<0.05). CONCLUSION: The incidence of stroke after acute MI is 2.9% and more frequent within the 4 days after MI. History of hypertension, previous stroke and congestive heart failure (CHF) were the factors independently favoring the occurrence of stroke, but there is no relation between the occurrence of stroke and anterior site of MI. Although intravenous thrombolytics followed by full anticoagulation treatment appeared to provide protection against ischemic stroke, it has no effect in the incidence of left ventricular thrombi in this study.

BACKGROUND AND OBJECTIVES: Qualitative oculomotor abnormalities have been reported in parkinsonian patients for many years, but conflicting results have been obtained. This study was performed to evaluate the correlation between the severity of the disease and the abnormalities of the ocular movements in idiopathic parkinson's disease. METHODS: We gave the vestibular function tests in patients with idiopathic parkinson's disease and normal controls. Eye movement recordings were made with automated electronystagmography and rotation test was performed. A total of 46 patients (mean age : 61.2+/-6.7) and 24 controls (mean age : 60.5+/-4.3) were studied. The severity of the disease was divided into two groups by modified Hoehn & Yahr staging ; H-Y stage 1 and 2 as a mild group and stage 3 and 4 as a severe group. RESULTS: Saccadic latency and accuracy, pursuitic gain and velocity, vestibulo-ocular reflex (VOR) suppression by vision were significantly altered in patients, whereas mean velocity of optokinetic nystagmus (OKN) and VOR gain in darkness were normal. Alteration of saccadic latency and accuracy, pursuitic gain and velocity, VOR suppression by vision were profound in the severe group compared with a mild group and controls, but the above parameters did not differ between a mild group and controls. In a hemiparkinson's group, saccadic latency and accuracy, pursuitic gain, OKN mean velocity and gain was not different between the both sides. CONCLUSION: The results indicate that severe Parkinson's disease damages nigrostriatal or other specific pathways which were involved in the regulation of the saccadic, pursuitic and pursuitic-mediated visual fixation system. In a hemiparkinson's group asymmetric damage of dopaminergic innervation which was involved in the regulation of ocular movements was not found.

Although some cases of benign positional vertigo are associated with a chronic ipsilateral sensorineural hearing loss, an association with simultaneous ipsilateral sudden deafness is rare. We report a 53-year old woman with sudden deaf-ness with simultaneous positional vertigo in the same ear characterized by benign paroxysmal positional vertigo of pos-terior semicircular canal type. After a modified Epley particle-repositioning maneuver, the patient's vertigo was resolved. Clinical and neuro-otologic evaluations suggested that the lesion responsible for this patient was probably located within inner ear rather than within the vestibulocochlear nerve.

A case of liver cell adenoma that was incidentally found at postmortem examination of a neonate who died of E. coli sepsis is described. The adenoma was a sharply demarcated, not encapsulated mass located subcapsularly in the right lobe, and was pale tan to light yellowish round nodule of 0.9 cm in diameter. Microscopically, the tumor was composed of sheets and cords of uniform and slightly enlarged hepatocytes separated by dilated sinusoids. There were no portal zones or central veins to suggest the normal lobular architecture. The nuclei were bland and the cytoplasm varied from clear to acidophilic, containing lipid vacuoles. Ultrastructural examination showed that the hepatocytes of the tumor had highly differentiated organelles, reminiscent of normal hepatocytes.

Foreign body ingestion in children is commonly encountered and this usually resolves spontaneously. Single magnet ingestion usually does not need additional medical treatment. However, multiple magnets can attract each other in intestinal loops and several complications can develop such as bowel obstruction and fistula formation. In this situation, endoscopic and/or surgical intervention is inevitably required. Therefore, making the correct diagnosis is needed for cases of magnets ingestion, and this should be done as soon as possible for children. We report here on a case of gastroduodenal fistula and duodenal obstruction caused by the interaction of four magnets.

We report a man who presented anterior chest pain with mild weakness of both hands while swimming. Initially, he was admitted to the department of internal medicine for evaluation and management of suspected myocardial infarction. Cardiac evaluations including coronary angiogram showed the patient to be normal. Spinal MRI showed a hyperintense signal on the sagittal T2-weighted images at the cervical spinal cord (C6-7). When a patient with chest pain shows weakness in both arms, not only cardiac evaluation but also spine work up is needed.

Objective/BACKGROUND: Serum levels of anti-acetylcholine receptor antibody (AChR-Ab), interleukin-2 (IL-2) and soluble interleukin-2 receptor (sIL-2R) may represent markers of disease severity in myasthenia gravis (MG). This study was performed to evaluate the correlations between disease severity and immunological parameters such as serum AChR-Ab, IL-2 and sIL-2R level and between each immunological parameters. METHODS: Serum levels of AChR-Ab, IL-2 and sIL-2R were measured in 30 MG patients and in 22 healthy controls. Results : Serum levels of AChR-Ab and sIL-2R were higher in MG than in healthy controls (p<0,01). The occurrence of IL-2 positive serum samples was 46.7% in MG but none in controls. There were no significant correlations between disease severity and immunological parameters and between each immunological parameters. Conclusions : Serum IL-2 and sIL-2R levels may not represent markers of disease severity in MG, In order to further document the correlation between each parameters, follow-up of individual patients with serial serum samplings may be necessary.

Lafora's disease is one of the major causes of progressive myoclonic epilepsy. The main clinical manifestrations are epilepsy, both generalized and focal, severe and progressive myoclonus, progressive dementia and cerebellar sign, then leading to death within 2-10 years. The definite diagnosis depends on the detection of the characteristic PAS positive inclusions, which are present in various tissues including the brain, liver, muscle and skin. We presented two brothers who showed typical clinical features of this disorder, confirmed by skin and muscle biopsy.

BACKGROUND: The development of new drugs or alternative therapies effective against methicillin-resistant Staphylococcus aureus (MRSA) is of great importance, and various natural anti-MRSA products are good candidates for combination therapies. We evaluated the antibacterial activities of a Phellinus baumii ethyl acetate extract (PBEAE) and its synergistic effects with beta-lactams against MRSA. METHODS: The broth microdilution method was used to determine the minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of the PBEAE. The PBEAE synergistic effects were determined by evaluating the MICs of anti-staphylococcal antibiotic mixtures, with or without PBEAE. Anti-MRSA synergistic bactericidal effects of the PBEAE and beta-lactams were assessed by time-killing assay. An ELISA was used to determine the effect of the PBEAE on penicillin binding protein (PBP)2a production. RESULTS: The MICs and MBCs of PBEAE against MRSA were 256-512 and 1,024-2,048 microg/mL, respectively. The PBEAE significantly reduced MICs of all beta-lactams tested, including oxacillin, cefazolin, cefepime, and penicillin. However, the PBEAE had little or no effect on the activity of non-beta-lactams. Time-killing assays showed that the synergistic effects of two beta-lactams (oxacillin and cefazolin) with the PBEAE were bactericidal in nature (Deltalog10 colony forming unit/mL at 24 hr: 2.34-2.87 and 2.10-3.04, respectively). The PBEAE induced a dose-dependent decrease in PBP2a production by MRSA, suggesting that the inhibition of PBP2a production was a major synergistic mechanism between the beta-lactams and the PBEAE. CONCLUSIONS: PBEAE can enhance the efficacy of beta-lactams for combined therapy in patients infected with MRSA.
