Daily in our practice we use terms of anatomy. Some of these terms are directly linked to the name of their discoverer. Very often, we ignore or have forgotten the history of these anatomists. The author, with a short repertory refreshes our memory.
Tenon's capsule is at the forefront of today's strabismus news. Its function as a muscle pulley was recognized by Tenon himself in 1806. Neiger, then Koornneef, and more recently Demer gave a more modern description of Tenon's capsule. The anterior or muscular part is made up of collagen, elastic, and smooth muscle fibers. It forms a sleeve around extraocular muscles from the Tenon foramen to their scleral insertion. Directly in front of the foramen, it includes a zone of strong capsular-muscular adherence, which is also solidly suspended by ocular suspension system to the periosteum of the orbit; the intermuscular membrane consolidates the adherence zones of the rectus muscles. The posterior part is simply a condensation of collagenous fibers. The function of Tenon's capsule is essential. At the place where it adheres to the muscles, the sleeve that it forms around the muscles plays the role of a pulley diverting the muscle's path, with the pulley representing the proximal functional insertion of the muscle. The position of a rectus muscle's pulley is stable during ocular movements perpendicular to the axis of this muscle because of the transversal and radial fastening of the capsular-muscular adherence zone. During movements along the muscle axis, the pulley moves with the ocular globe. In fact, it is positioned actively to accompany the ocular globe's movements. The anomalies of these pulleys can contribute to or be responsible for an extraocular muscle imbalance: a position anomaly, an instability, a displacement, or a pathological adherence of one pulley can be the cause. Surgery of Tenon's pulley has always been an integral part of extraocular muscle surgery. Any intervention on the muscular level involves, to a lesser or greater extent, the operated muscle's pulley. Different examples demonstrate this.

Several aspects of Shrapnell's career are still little known or erroneously typed. 1. Some historians of Medicine profess that Dr. Shrapnell was the inventor of a shell which bears his name. 2. Others neglect the negative points of Shrapnell's paper published in 1832 on the pars flaccida. To be able to comment on these different aspects of Shrapnell's life and work we compared the biographies of the anatomist and of the artillery officer. We noticed the positive and also the negative points of his paper. We conclude that: 1. Dr. Shrapnell was not an artillery officer, but the two men were present in the British Army; their surnames, their names and the period when they lived were about the same. 2. Errors in Shrapnell's paper were due to the philosophy and lack of anatomical and pathological knowledge of the time. 3. Otologists' reception was better than that of the Anatomists because for the Otologists, Shrapnell's membrane was recognized as an important original area of cholesteatoma, whereas for the Anatomists it was just a detail.
Morgagni, Baillie, and Rokitansky were three giants in pathology. They established the foundations for classification of diseases. Their combined contributions to clinical knowledge outweighed all that had been learned in medicine in the prior history of the human race. It is remarkable that their achievements were made without using microscopy.
Temporary occlusion of large vessels (the Matas test) to test the adequacy of collateral circulation is part of daily clinical practice. Nevertheless, only a few clinicians are aware of Rudolph Matas and his pioneering work in different fields of medicine. A legendary New Orleans surgeon, Rudolph Matas (1860-1957) lived nearly a century. During that time he witnessed enormous progress in medicine and greatly contributed to its evolution. He is unanimously recognized as the father of modem vascular surgery for his creation and popularization of aneurysmorrhaphy, a technique for the definitive treatment of aortic and peripheral aneurysms. He also made significant contributions to the then burgeoning fields of anesthesia, critical care, and infectious disease (yellow fever in particular). In 1911, he wrote a landmark article in which he described a challenge test to assess the degree and efficacy of the collateral circulation in patients under consideration for permanent occlusion of a major vessel. Matas studied the feasibility of such a test by temporarily occluding the carotid and femoral arteries in dogs for variable periods of time. In the introduction to his seminal article on the subject, he stated that "the chief object of this inquiry has been to determine whether the large arteries can be occluded long enough to make it possible to observe the effect of the arrested circulation in the territory supplied by the occluded vessel, without irreparably damaging the artery during the period of observation." He definitively achieved his stated goal: the Matas test, although greatly modified by contemporary endovascular techniques to be safer and more reliable, is in essence still routinely performed worldwide 90 years after its initial description.
Untreated rupture of an aneurysm of the abdominal aorta is fatal in almost 100% of the patients. In the majority of cases the assessment of a correct, early diagnosis is simple (hypotension, backache, abdominal pain, pulsating resistance in the abdomen) and makes a prompt surgical or endovascular operation possible. In some instances however rupture of aneurysms of the abdominal aorta simulates other clinical conditions (acute cholecystitis, acute diverculitis of the sigmoid) which may delay the correct diagnosis and reduce the patient's chance of survival. The author describes, based on historical documents, the treacherous course of the disease in the scientific genius Albert Einstein where rupture of an aneurysm simulated acute cholecystitis, and in the world literature this symptomatology was subsequently described as Einstein's sign.

The aim of our paper is to describe Kandinsky-Clerambault's Syndrome, which has important cultural-historical value in the history of psychiatry, and to illustrate the syndrome by means of a case report. Although its component symptoms are known among Western psychiatrists, the syndrome's specific name is generally unknown. The authors suggest that detailed clinical descriptions of some specific conditions may contribute to a more detailed knowledge of psychopathology, a more colorful and memorable view of conditions, with an increased awareness of the historical and cultural origins of psychiatry.
Superficial thoracic wall and dorsal vein of the penis phlebitis are uncommon diseases. Both are known as Mondor's disease. Two cases have been diagnosed in a short period of time in a Southern. Spain primary care clinics.
