Still baffled by "cuiboliani" pneumonia...not in any sort of medical texts that I've ever seen. Though of course bad handwriting could make it look so when it was something else entirely?
Closest I can think of is Chlamydia pneumoniae, the name of a pneumonia-causing virus. It's a close cousin to the virus causing psitticosis, AKA "parrot fever".
Or maybe it could be Coccidioides immitis, a fungus causing pneumonia.
Of course, it could also be some obscure and archaic name for a sort of pneumonia...there are just about as many ways to contract the disease as you'll find stars in the sky.
The pulmonary phlebitis was likely a contributing factor--chest and adbominal surgery/injury causes the inability to take deep breaths, which can more easily cause pneumonia. Phlebitis would be rather like Boxhall's pleurisy in that breathing would likely be difficult and painful and more readily lead to the pneumonia.
On phlebitis, it's more likely to develop in pregnant women and those who are bedridden, so that makes sense.
