Cerebrovascular Complication in Tuberculous Meningitis

BACKGROUND: Cerebral infarction as a complication of tuberculous meningitis (TBM) is not uncommon, but has been rarely reported. The purposes of this study were to evaluate the clinical characteristics of cerebral infarction secondary to TBM and investigate the predictive values for cerebral infarction in patients with TBM. METHODS: We prospectively collected patients with TBM for 24 months. Patients were divided into two groups, either patients with stroke or without stroke. We compared the demographic features, clinical, laboratory, and neuroradiologic findings between the two groups. We classified the stroke subtype with neuroimaging findings. RESULTS: The 26 patients were diagnosed as TBM, and 6 patients had complications with cerebral infarction. The neutrophil percentage in the cerebrospinal fluid (CSF) leukocyte were significantly higher in patients with stroke than in patients without stroke (p=0.0098). On initial CT scan, meningeal enhancement was found in 9 patients, and 4 of them complicated with stroke. However, there were no significant differences in the other clinical and laboratory features such as demographic features, interval between meningitis onset time and treatment initiation time, peripheral white blood cell count, and CSF findings. In six patients with stroke, lacunar infarctions and non-lacunar territorial infarctions were found in 3 patients, respectively. In territorial non-lacunar infarction patients, one patient died due to herniation. CONCLUSIONS: We suggest that the possibility of cerebral infarction under the treatment of TBM should be considered, when the patient shows focal neurologic signs, meningeal enhancement on the CT scan and sustained polymorphic CSF pleocytosis.

Cerebral White Matter Lesions and Apolipoprotein E polymorphism

BACKGROUND: Cerebral white matter lesions(WMLs), such as leukoaraiosis, may be related to damage from cerebral ischemia and may also be associated with the degenerative process. The apolipoprotein E (APOE) 4 allele is a risk factor for degenerative diseases, such as Alzheimer`s disease, and ischemic brain damage through acceleration of atherosclerosis. No study has been performed regarding WMLs and APOE genotype in Korea. We investigated the association between WMLs and APOE among Koreans. METHODS: Brain MRI was performed in 225 subjects(ages 61 to 85 years) without neuropsychiatric disease randomly selected from the Ansan Health Cohort Study. WMLs observed on 225 MRI scans were rated in terms of severity by 2 raters. All study subjects underwent APOE genotyping. RESULTS: WMLs were observed in 109(48.4%) of subjects. In the subjects with WMLs, the distribution of APOE genotypes was 0.9% for epsilon 2/epsilon 2, 11.0% for epsilon2/epsilon3, 1.8% for epsilon2/epsilon4, 61.5% for epsilon3/epsilon3, 22.9% for epsilon3/epsilon4, and 1.8% for epsilon4/epsilon4, respectively. The distribution of APOE genotypes did not differ between subjects with and without WMLs. CONCLUSION: These data suggest that there is no association between WMLs and APOE genotypes in Koreans.

A Case of Pachydermoperiostosis / 대한피부과학회지

Pachydermoperiostosis is a very rare hereditary disease characterized by hyperostosis, clubbing of fingers, coarse skin, furrowing, oiliness of the skin of the face, marked furrowing of the scalp, hyperhidrosis of the hands and feet and elephant feet. This condition affects males more often than females, and it's first evident is during adolescence. We report a case of pachydermoperiostosis in a 21-year-old male who developed mild clubbing of phalanges and spade-like enlargement of the feet and progrssive thickening of the skin of his face, palm and sole since puberty.
