Thank you very much, that solves it!

Hi all,

I have come across a very curious phenomenon in LaTeX; below is a minimal working example. All text after the \theorem{Hello} is still italicized!

\documentclass{article}
\usepackage{amsthm}

\begin{document}

\newtheorem{theorem}{Theorem}[section]

Hello

\theorem{Hello}

hi

\end ...
