Rumänien
I'm sorry for any confusion, but "Rumänien" is the Swedish name for the country "Romania." It seems there might be a misunderstanding in your request as "Rumänien" is not a medical term or concept that can be defined in a medicinal context. If you have a question about Romania's healthcare system or medical practices, I would be happy to help with that.
Europe, Eastern
There is no universally accepted medical definition for "Eastern Europe." The World Health Organization (WHO) and the United Nations (UN) do not have specific definitions for geographical regions in Europe based on eastern and western divisions. These divisions are often based on historical and cultural lines, and their interpretation can vary.
