    Abstract Dural AVMs can produce a wide variety of symptoms related to raised intracranial pressure, venous congestion, and cerebral ischaemia. We present a unique case of reversible dementia, due to venous hypertension. The cerebral ischaemia was caused by extensive bilateral arteriovenous malformations of the external carotid system, which drained into the superior sagittal and transverse sinuses and resulted in venous hypertension. Although partial occlusion by endovascular embolization and ligation procedures had some effect, only ‘scalping and silastic implantation' gave satisfactory amelioration of symptoms.

    Notes:
    Abstract: Although genetic factors have been strongly implicated in determining bone mineral density (BMD), the role of the vitamin D receptor (VDR) polymorphism remains controversial. An overall consensus is difficult, as the populations studied have been heterogeneous with respect to menopausal status and ethnicity. Moreover, some studies have examined only small populations, and relatively few studies have been conducted in Asian populations. There is mounting evidence that calcium homeostasis in Asian populations differs from that in Caucasians. This difference may be mediated, in part, through VDR effects. In a cross-sectional study we have examined the relationship between the VDR polymorphism and BMD in 272 women (mean age 75 years) and 237 men (mean age 73 years) of Chinese origin from Hong Kong. Consistent with other studies in Asian populations we found higher frequencies of the T, b and a alleles compared with those reported in Caucasian populations. Moreover, no significant difference in BMD was observed when subjects were grouped by a combination of the genotypes (bbAATT, bbAaTT, bbaaTT, BbAaTt, BbAATt). These results suggest that VDR polymorphism is not associated with BMD in elderly Hong Kong Chinese men and women.
