[History of anatomy in Lyon].

1. We know very little concerning the teaching of anatomy during the Middle Ages. Only two authors, who both came to live in Lyon, Lanfranc and Guy de Chauliac, wrote on the subject. On the other hand, the important development of printing in Lyon from the sixteenth century onwards, made it possible to spread the translations of classic works and most of the books on Anatomy of the Renaissance. 2. However, Lyonese Anatomy developed very slowly because hospital training was more often badly organized. The only true supporter of Anatomy has been Marc Antoine Petit, chief surgeon of the Hôtel-Dieu before the French Revolution. 3. Apart from the parallel but only transient teaching of the Royal College of Surgery, one will have to wait for the creation of an official teaching first assumed by "schools" (secondary school and preparatory school) and finally by the Faculty of Medicine created in 1877. The names of Testut and of Latarjet contributed to the reknown of the Faculty of Medicine by their anatomical studies of great value for several generations of students. 4. Recently the Faculty of Medicine has been divided into four "universities". The new buildings are larger. The "gift of corpses" has brought a remedy to the shortage of the last twenty years. Anatomical research can be pursued thanks to micro-anatomy and bio-mechanics while conventional teaching is completed by dissection.

[Non-recurrent inferior laryngeal nerve (15 operative cases)].

During surgery on the right thyroid lobe, 15 cases of non-recurrence of the inferior laryngeal nerve were observed, among which two types of equal frequency. Embryologic data explain why this abnormality is always associated with an abnormal origin of the right subclavian artery, directly from the aortic arch. The right subclavian artery generally passes behind the oesophagus in these cases. These 15 cases represent 0,79% of the 1889 cases studied during a short period (1971-1978).

Bovine ostertagiosis, a review. Analysis of types and syndromes found in France by post mortem examinations and total worm counts.

We have completed an analysis of the total worm counts (including digests) performed on 74 weaned cattle of various ages and sacrified in our laboratory. We identified 21 cases of animals suffering from Ostertagiosis (harbouring over 40,000 adults + immatures in the lumen and the mucosa) or moribund animals showing symptoms and lesions of Ostertagiosis. The results are presented with the Parasite profiles (percentage of G.I. genera) and Parasite levels ("Very low, Low and Average" for carrier animals and "High" and "Very High" for animals suffering from parasitism). We have observed typical cases of Type I on weaned calves but not on calves grazing when suckling their own dams (Charollais, Limousin type), Pretype II and typical Type II on 2 year old or older animals. Variants of Type II were found : Fasciologis/Ostertagiosis complex and Parturient Ostertagiosis which seems to be well-known by practitioners. Complexes of a clinical Type II + stage of Pretype II with 1 to 2 million hypobiotic L4 larvae could explain the difficulty to control very severe diseases. Oedematous ostertagiosis is also described as an original type or syndrome in 2 to 3 year old cattle : the typical lesion is a dramatic oedema of the abomasum which is found enlarged up to X 2 or X 3 times its normal size/weight. The abomasal folds and the edges are filled with a watery oedema and have an appearance of "foetal membranes". As only few parasites are present the disease is considered to be an allergic over reaction in adult animals. It is recommended that the peptic digestion of the abomasal mucosa and differential counts of the various developmental stages of the parasites be added to the routine technique used in diagnosis laboratories.

[Fibrous arch of the adductor muscle of the thumb (musculus Adductor pollicis)].

In 8 out of 30 cases we found the fibrous arch of the Adductor pollicis muscle. In 4 cases, the resistant arch is situated between the 2 fasciculi of the Adductor Pollicis and inserted on the upper third of the third metacarpian on its anterior face. Il resists a traction of 500 g.; in 4 other cases, it is less resisting. The connections with the deep cubital vasculo-nervous fasciculus are important, especially the deep branch of the cubital nerve which can be compressed at this level.
