I saw the "hot cross bun" sign: a knead-to-know finding.

The "hot cross bun" sign is a rare radiologic sign seen on magnetic resonance imaging that can help direct the diagnosis of the cerebellar subtype of multiple system atrophy. It indicates damage to the transverse pontocerebellar fibers and can be seen in other pathologies including spinocerebellar ataxia. The name for this radiologic sign was coined in 1998, likening the cruciform hyperintensity on imaging to the English spiced bun marked with a cross and historically eaten on the Christian religious holiday Good Friday.

Disaggregating Asian American Cigarette and Alternative Tobacco Product Use: Results from the National Health Interview Survey (NHIS) 2006-2018.

Introduction: Asian Americans suffer high rates of smoking and tobacco-related deaths, varying by ethnic group. Trends of cigarette and alternative tobacco product use among Asian Americans, specifically considering ethnic group, sex, and nativity, are infrequently reported.

Methods: Using National Health Interview Survey (NHIS) data from 2006-2018 and the 2016-2018 alternative tobacco supplement (e-cigarettes, cigars, smokeless tobacco, pipes), we explored cigarette and alternative tobacco product use by Asian ethnic group (Asian Indian (n = 4373), Chinese (n = 4736), Filipino (n = 4912)) in comparison to non-Hispanic Whites (NHWs (n = 275,025)), adjusting for socioeconomic and demographic factors.
