Sudden death due to amyloidosis of intramural coronaries in a patient with amyloidosis of hip joint - An autopsy report with a review of literature.

Amyloidosis is caused by an extracellular accumulation of insoluble fibrillary protein predominantly in the kidneys, spleen, and heart. The deposition of amyloid into the joints, synovia, and osseous tissues (amyloid arthropathy) is an uncommon condition with only a few case reports in the English literature. Similarly, amyloid deposition predominantly limited to the vascular wall is rarely described.

Oesophageal speech using tracheo-oesophageal-valved prostheses is now considered the state-of-art in postlaryngectomy voice rehabilitation. One of the major drawbacks of voice prostheses is their limited device lifetime.
