<s>[INST] Hello. Can you please help me understand the way in which actor Rudolph Valentino died back in 1926? I realize this is silly, but I m in love with him and I would like to fully understand what happened to him. Some say it was a perforated ulcer others say peritonitis and that as his condition grew worse, he developed pleurisy. I don t understand. Please help, if you have the time.Thank you. [/INST] A perforated ulcer causes peritonitis which gradually involves all intro abdominal organs. Fluid gets collected and infection sets in. These causes increased intro abdominal pressure. Ultimately the diaphragm gets involved making the infection reach pleural cavity and in turn causes pleurisy which is infection of pleura. As a result septicemia sets in and the patient dies. This could be a probable cause of Rudolph Valentino's death. Good to see such an ardent fan!! </s>
