Validation study of the Mini-Mental State Examination in a Malay-speaking elderly population in Malaysia.

Background/aims: In view of the differing sensitivity and specificity of the Mini-Mental State Examination (MMSE) in the non-English-speaking populations, we conducted the first validation study of the Malay version (M-MMSE) in Malaysia among 300 subjects (from the community and outpatient clinics).

Methods: Three versions were used: M-MMSE-7 (serial 7), M-MMSE-3 (serial 3) and M-MMSE-S (spell 'dunia' backwards). Dementia was assessed using the criteria of the Diagnostic and Statistical Manual of Mental Disorders IV.

Serological evidence of possible human infection with Tioman virus, a newly described paramyxovirus of bat origin.

Tioman virus, a relatively new paramyxovirus, was isolated from fruit bats (Pteropus species) on Tioman Island, Malaysia, in 2001. The objective of this study was to determine the prevalence of antibodies to T. virus in island inhabitants, by use of comparative ELISA and serum neutralization assays.

Racial background is a determinant factor in the maintenance dosage of warfarin.

Warfarin is a drug commonly used in the prevention of thromboembolic events. There have been reports suggesting that racial background may influence warfarin dose requirements. Malaysia is a multiracial country in which there are 3 major races, Malay, Chinese, and Indian.

Nipah virus infection: pathology and pathogenesis of an emerging paramyxoviral zoonosis.

In 1998, an outbreak of acute encephalitis with high mortality rates among pig handlers in Malaysia led to the discovery of a novel paramyxovirus named Nipah virus. A multidisciplinary investigation that included epidemiology, microbiology, molecular biology, and pathology was pivotal in the discovery of this new human infection. Clinical and autopsy findings were derived from a series of 32 fatal human cases of Nipah virus infection.

Relapsed and late-onset Nipah encephalitis.

An outbreak of infection with the Nipah virus, a novel paramyxovirus, occurred among pig farmers between September 1998 and June 1999 in Malaysia, involving 265 patients with 105 fatalities. This is a follow-up study 24 months after the outbreak. Twelve survivors (7.

Nipah encephalitis outbreak in Malaysia, clinical features in patients from Seremban.

Background: An outbreak of viral encephalitis occurred among pig industry workers in Malaysia in September 1998 to April 1999. The encephalitis was attributed to a new paramyxovirus, Nipah virus. This is a description of the clinical features of 103 patients treated in the Seremban Hospital with characterization of the prognostic factors.
