[Chromatography of urinary amino-acid in bismuth encephalopathy (author's transl)].

The urinary excretion of amino-acid have been determined by ionic exchange chromatography for 10 cases of bismuth encephalopathy and for 15 normal controls. The ninhydrine positive constituant reported by Burns in 5 cases of encephalopathy has not been detected. We are thinking it may be related to the use of a rich amino-acid solution during perfusions. We did not find any significant difference between the urinary excretion of amino-acid average value to the two groups. We found an increase excretion when severe encephalopathy were observed. Separate analysis of individual amino-acid excretion showed the following results: i) average percent of tyrosine excretion is lower in controls as in encephalopathies; ii) among the different ratios tested only SER + THR)/TYR and VAL/TYR are different in the two groups.

[Surgical treatment of loss of substance of the lower lip].

Repair of loss of substance of the lower lip has been the object of numerous studies. Each author has used his own ingenuity to describe a new type of flap aimed at restoring a particular form of loss of substance. The techniques suggested here are capable of solving a majority of problems on the basis of simple and original solutions. These flaps make it possible to resolve the problems posed by most cases of loss of substance of the lower lip. The choice of these plastic procedures permits restoration which is at one and the same time functional and anesthetic.

[Functional anatomy and terminal tubules of Stensen's duct].

The dynamic anatomy of STENSEN's duct is somewhat different from what is usually accepted. GUERRIER, COURBIER and FRANCHEBOIS had indeed admitted that the buccinator msucle acted as a passive sphincter, without however mentioning the presence of terminal siphons and canalar valvules and without drawing particular attention to their dynamic relationship. This duct should not be considered inert, as part of a theoretical bayonet-like pathway which is more topographical than functional: the buccinator muscle and STENSEN's duct with its valvules and terminal siphons should be considered together as forming the real salivation apparatus.

[The temporomandibular joint in the newborn infant. Oto-meniscal relations].

Although they are anatomically immature at the time of birth, the temporomandibular joints are able to ensure efficient suction due to the branchial blastema interposed between the two articular nuclei. This conjunctive formation is the principal factor in the constitution of the meniscus and its frena, the articular surfaces, the capsule and the ligaments. This constitutes not only an embryological but also a functional entity. The joint runs the risk of paying heavily for this functional availability, by its relationship with the ear-drum which is a potentially infectious cavity. In fact, at birth there is still evidence of the original branchial continuum between the unknit tympanal and squamosal in the shape of the posterior meniscal frenum, the conjunctivo-vascular isthmus which puts the vascularization of the mucosa of the ear-drum in communication with the very rich vascularization of the neonatal temporo-mandibular articulation. Therefore, 1/3 of the so-called congenital temporo-mandibular ankyloses, apparently without cause, could probably be explained by the otomeniscal relationship existing in the new-born baby and continuing during the first few months of life in the atmosphere in the form of a conjunctivo-vascular link.

[Masticatory sysarcosis. Significance in maxillofacial surgery and pathology].

The masticatory muscles and the vertical ramus move in a closed aponeurotic lodge; sliding spaces containing cellulo-adipose formations, veritable sysarcoses, are situated between the muscles of mastication as well as between these muscles and their osteo-aponeurotic covering. Sysarcoses are embryological, anatomical and functional units. Bichat's ball must be considered as being the antero-inferior pole of these cellulo-adipose containing spaces. Apart from the mechanical role of these spaces, their value in pathology and in traumatological surgery must again be pointed out, because firstly they are the pathways of approach and fixation of fractures of the zygomamalar region. They are also of great value in reparatory surgery as knowledge of the vascularization of the fat in these spaces enables the making of flaps of fat in the surrounding area.
