BACKGROUND: High-resolution carotid ultrasonography is considered a fundamental technique for the investigation of the vascular system. However, it is still very unclear whether ultrasonographic studies of carotid arteries are useful for the prediction of cardiovascular events in patients with coronary heart disease. We have tried to assess the usefulness of carotid ultrasonography to predict the severity of coronary artery stenosis in the patients with ischemic heart disease. METHODS: We studied in 80 patients(53 men, 27 women) with acute chest pain, mean ages 63.1 10.8 yr(35 to 84 yrs), who underwent both coronary angiography and carotid ultrasonography with 10 MHz transducer. The patients who had received revascularization procedure were excluded. We classified the patients into two groups, the control group without significant coronary stenosis(23 patients) and the coronary artery disease(CAD) group(57 patients) with significant stenosis(>50%). The intima-media thickness (IMT) was measured in the far wall of CCA at 10 mm proximal to carotid bulb and the abnormal IMT was defined when the measurement was greater than mean IMT+2 SD of control group(>0.99 mm). Serum total cholesterolQlC), low density lipoprotein(LDL), high density lipoprotein(HDL), triglyceride(TG) and lipoprotein (a) (LP(a)) were measured and history of hypertension, diabetes mellitus, and smoking were investigated. RESULTS: A significant difference in IMT of the CCA was found between control and CAD group(0.75+/-0.12mm vs. 1.02+/-0.34 mm; p<0.001). Also a significant difference in the existence of plaque(control; 26.1% vs. CAD; 73.7%, p<0.00l) and the number of plaque(control; 0.39+/-0.94 vs. CAD; 2.20+/-1.87 p<0.001) was found. The existence and number of carotid plaque were more conelated with coronary artery stenosis severity than carotid IMT. The sensitivity of IMT for prediction of significant CAD was 42.1%, the specificity 95.7%, the positive predictive value 96%, and the negative predictive value 40%. The sensitivity of plaque presence on the carotid artery for prediction of CAD was 73.7%, the specificity 73.9%, the positive predictive value 87.5% and the negative predictive value 53.1%. Among the risk factors, age and LP(a) were correlated with IMT of CCA, and diabetes, hypertension, age were correlated with the presence of plaque. Smoking and hypertension were correlated with coronary artery disease. CONCLUSION: Carotid atherosclerosis was significantly correlated with severity of coronary atherosclerosis. We therefore suggest that carotid ultrasonography is useful to predict the severity of coronary artery stenosis and that the best index of coronary artery stenosis severity may be carotid plaque rather than carotid intima-media thickness.

A 9-year-old Korean boy with lissencephaly was found dead at home. He had previously been diagnosed with lissencephaly that presented with infantile spasm on the basis of magnetic resonance imaging and electroencephalogram results. Antemortem chromosomal banding revealed a normal karyotype. A legal autopsy was requested to eliminate the possibility of neglect or abuse by his parents. The autopsy findings revealed type I lissencephaly with the associated microcephaly. No external wounds or decubitus ulcers were noted. Postmortem fluorescence in situ hybridization for the LIS1 locus and nucleotide sequence analysis of the whole coding regions of the LIS1 gene did not reveal any deletions. The antemortem and postmortem findings revealed that lissencephaly syndrome was associated with isolated lissencephaly sequence. External causes of death were excluded by the full autopsy and toxicology test results. Because patients with mental retardation are frequently victimized and suffer neglect or abuse, thorough external and internal examinations should be conducted at the time of autopsy.

The present report discusses four cases of chronic renal failure, which developed symptoms of parkinsonism in response to levosulpiride. The temporal relationship between levosulpiride discontinuation and the disappearance of parkinsonism suggests a causal link. In addition, decreased striatal dopamine transporter bindings assessed by [I-123] IPT SPECT were observed in two patients suggesting that a dopamine blocking agent causes the dysfunction of nigrostriatal dopaminergic neurons and that such injury may be involved in the pathogenesis of drug-induced parkinsonism.

Flumazenil, an imidazobenzodiazepine, is the first benzodiazepine antagonist and is being used to reverse the adverse pharmacological effects of benzodiazepine. There have been a few reports on the central nevous system side effects with its use. We report a patient with generalized ballism following administration of flumazenil. The mechanism through which flumazenil induced this symptom is unknown. It is conceivable that flumazenil may antagonize the GABA-benzodiazepine receptor complex and induce dopamine hypersensitivity, thus induce dyskinesic symptoms.

Intraspinal bronchogenic cysts are rare congenital cystic lesions. In all the reported cases, the cysts have been located in the cervical, upper thoracic or thoracolumbar segments. We report the case of an intraspinal bronchogenic cyst in the sacral location. We present the case of a 5-month-old female with a skin dimple in the midline over the sacral vertebra. Magnetic resonance image of the lumbar and sacral vertebra revealed a dermal sinus tract and an epidural cystic mass at the S2 level. The patient underwent the removal of the dermal sinus tract and the cyst. The cystic mass was shown to be connected to the subarachnoid space through a slender pedicle from the dura. The cyst was diagnosed to be a bronchogenic cyst based on the results of the histopathological examination. We conclude that intraspinal bronchogenic cysts may appear in the sacral location.

BACKGROUND: The aim of this study was to clarify to what extent bacterial meningitis could be distinguished from aseptic or tuberculous meningitis through C-reactive protein (CRP) in adults. METHODS: We retrospectively analyzed the medical records of 91 patients aged 15~81 years who had been hospitalized for acute meningitis and underwent lumbar puncture due to suspected central nervous system infection. RESULTS: We included 50 patients with aseptic meningitis, 23 patients with acute bacterial meningitis, and 18 patients with tuberculous meningitis. Blood CRP was higher in bacterial meningitis. None of the patients with bacterial meningitis had a CRP value of under 20 mg/dl. The CRP values were under 20 mg/dl in 92% of the patients with aseptic meningitis and in 73% of those with tuberculous meningitis. Taking a CRP level of above 20 mg/dl as a positive discriminatory factor for bacterial meningitis, the sensitivity and specificity were 1.0, 0.88. To better predict whether a patient has bacterial or nonbacterial meningitis, we developed a canonical discriminant function equation using CRP and CSF parameter, and finally concluded that blood CRP was a good predictive indicator that differentiated bacterial meningitis from aseptic or tuberculous meningitis at admission. CONCLUSIONS: The CRP measurement, is easily performed and inexpensive. We believe it is worth analyzing CRP whenever meningitis is suspected, it can also limit the unnecessary use of antibiotics.
