Commentary: coronary interventions--overview of a 16-year odyssey based on pathoanatomy: angioplasty, atherectomy, and calcifectomy.

The last 16 years have seen the development of a variety of coronary interventional procedures based on pathoanatomy. New terms have been introduced, such as atherectomy for excision of atheroma. Coronary calcification occurs in the intima and is an important marker of significant coronary artery disease. Echocardiography of the coronary arteries can detect atheroma and calcification. Ultrafast computed tomography can quantify extent of coronary calcium. New devices, such as the rotablator, can specifically treat calcified lesions, and a lesion-specific approach is now possible. The removal of atheroma is called atherectomy. The removal of calcium is called calcifectomy. New procedures spawn new terms. Atherectomy and calcifectomy complement each other, and enable us to be specific about the pathoanatomy and the matched interventional device used. This article is an overview of the evolution of lesion-specific devices and the terminologies pertaining to their use.

Metastatic tumors of the umbilicus: a review 1830-1989.

Umbilical metastases from known and unknown primary cancers are rare. The eponym "Sister Mary Joseph's nodule" has been used by generations of physicians. The first reports of this clinical sign were from Walshe in 1846. A review of the literature revealed 265 cases from then until 1989. Only 85 cases of umbilical metastasis from unknown primary tumors were found. This review should help us to focus on the common and uncommon primary sites in the diagnosis of patients with this finding. A single case report and the work-up for the hidden primary tumor are described.

Odyssey of a sailor's diagnosis since 1795 AD.

In the year 1795, a British East Indiaman bound for China had a sick sailor on board who was diagnosed as having testis cancer by the ship's surgeon, who then treated him with an antiscorbutic diet, because scurvy was rampant among the sailors. He was completely cured of his cancer, as reported in the Edinburgh Medical and Surgical Journal by Livingstone in 1805. However, the sailor actually had scurvy and not testis cancer. This diagnostic error has been perpetuated in the medical literature until rectified by Shetty after 191 years. This is reconstructed account of the sailor's case history and the ship's journey as it actually took place in 1795 AD.
