Caleb Hillier Parry
Caleb Hillier Parry ( born October 21, 1755 in Cirencester, † March 9, 1822 in Bath ) was an English physician. He is the first to describe the hyperthyroidism (1786, published 1825) and Parry - Romberg syndrome. He devoted himself to further studies of the arterial pulse and the angina pectoris.
Life
Parry, eldest son of the pastor Joshua Parry and his wife Sarah Hillier learned during his school days at Cirencester Grammar School the young Edward Jenner, with whom he formed a lifelong friendship. Jenner was later to devote his work to Enquiry into the Causes and Effects of the Variolae vaccinae. From 1770 to 1773 Parry visited the Dissenters ' Academy in Warrington. He then studied medicine at Edinburgh University. 1775 was followed by a two -year stay at Thomas Denman in London, then Parry returned to Edinburgh, where he was in 1778 received his doctorate with a thesis on rabies ( De rabie contagiosa vulgo canina ). He married in the same year Sarah Rigby and traveled with her for nine months, the Netherlands and France. 1779, the couple settled in Bath, where Parry's practice, however, started off sluggish. 1785 visited the suffering from angina pectoris anatomist and surgeon John Hunter the spa town of Bath and was supervised during his stay by Caleb Hillier Parry. This increased its reputation locally clear Parry's practice flourished increasingly. Among his patients in Bath included William Herschel, Edmund Burke and naval officers like Admirals Richard Howe and George Rodney. 1789 Parry had an estate in the north- east of the city building, he also bought land in order to pursue his lifelong passion, and sheep. From 1799 to 1817 Parry was on General Hospital operates ( later The Royal Mineral Water Hospital ) and at the Casualty Hospital in Bath.
On October 28, 1816 health already battered Parry suffered a stroke that paralyzed him on the right side and his speech impaired ability. Until his death he was still searching active. He died on 9 March 1822 and was buried in Bath Abbey.
Caleb Hillier Parry's sons were the physician Charles Henry Parry (1779-1860), who published his records after his father's death, and the admiral and Arctic explorer William Edward Parry ( 1790-1855 ). The couple had seven more children.
Work
Parry was interested in many things, he was concerned with the collection of fossils and belonged in 1807 to the founding members of the Geological Society of London.
From 1788 to 1793 found a regular meeting of the Gloucestershire Medical Society, a gathering of country doctors, including Parry and Jenner, at the Fleece Inn, Rodborough in Stroud instead. In a lecture on angina pectoris Parry laid in July 1788 the foundations of his 1799 published font Inquiry into the Symptoms and Causes of Syncope anginosa, Commonly called angina pectoris before, in which he and Jenner basis of individual cases and their autopsy findings on pathological changes in the coronary arteries ( " ossification " ) and the aorta was received and creates a connection to the symptoms of angina pectoris.
1816 Parry published findings on the arterial pulse, which he had taken part in animal testing; including the conclusion that the arterial pulse is due to the rhythmic contraction of the heart. He also noted that a compression of the common carotid artery in the region of the carotid sinus leads to a drop in heart rate. This mechanism was later recognized as Karotissinusreflex. Parry examined the effect of such compression in various diseases.
A published until three years after Parry's death collection of medical writings also shows him as one of the first to describe Parry - Romberg syndrome, hemiatrophy of the face. In the same publication, also provide case descriptions of Hirschsprung's disease and hyperthyroidism. The first of the eight case descriptions for hyperthyroidism had Parry in 1786 and produced, by which he is one of the Erstbeschreibern.
A 900 works comprehensive collection of medical literature has been passed after Parry's death by his son to the Royal United Hospital in Bath, then came to a municipal library, and in 1950 was donated to the University of Bristol. The collection includes, among others, early modern works of William Harvey, Andrew Boordes and Santorio Santorios.
