[Total rectal prolapse in children. Modified Lockhart-Mummery operation].

A variant of the Lockhart Mummery operation for complete rectal prolapse in children is described. The modification consists of inserting a polyglactin mesh in the retrorectal presacral space. Nine children have been operated upon and followed up, some of them for more than 2 years. The immediate and long-term post-operative course has been satisfactory in all cases.

[Comparative anatomy of the velopharyngeal complex in mammals--excluding primates (1)].

From the anatomic element known with the man by the name of soft palatal-pharyngeal sphincter and which takes a major part in the phonation, the swallowing, the breathing, we have studied the evolutive morphology of the soft palatal-pharyngeal unity in several mammals. This unity which includes the levator palati and palatopharyngeus muscles is confirmed by the phylogenic and embryologic investigations. The comparative anatomy of the rat, rabbit, sheep and lion, allows to make obvious a evolutive line characterized by the gradual divergence of the axis of the two muscles common to the soft palatal and pharyngeal musculature, which could correspond with a phylogenic evolution.

[Comparative anatomy of the velopharyngeal complex in human and non-human primates (2)].

The authors describe the soft palatal-pharyngeal unity, composed of the levator palati and palatopharyngeus muscles in the adult man, the new-born and the Saimiri. They recall the importance of the soft palatal-pharyngeal sphincter in the man's phonation. After having described the general evolution of the aerodigestive tract in the no human mammals and the man, notions of evolutive morphology of the soft palatal-pharyngeal unity are established. They are characterized by the gradual divergence of the axis of the 2 muscles forming the soft palatal-pharyngeal unity ending in the appearance met in the adult man, indispensable in view of a soft palatal-pharyngeal ability allowing a articulated language.

[Contribution of radiological technics to the study of the mandibular canal. Application to human fossils and comparison with modern man and Pongidae].

Fossil mandibles from the "La Chapelle-aux-Saints" Man and Cro-Magnon "old man" are considered to be representative of Neanderthal and Cro-Magnon era. Radiographic studies of such mandibles - including C. T. Scan and panoramic views in common use in maxillofacial surgery - allowed the authors to make useful comments: the mandibular canals are nearly similar to those in Modern Man and quite different from those in Pongidae; the imaging was of adequate quality for a good evaluation of fossil internal structures.

[Optical methods in the study of superficial displacements of the lumbar vertebrae under a vertical load. Initial results and methodological aspects].

In order to assess superficial displacements under load in human lumbar vertebrae, the authors used three different optical methods: photogrammetry under non coherent light; double-exposure holographic interferometry; speckle granularity under laser exposure. Without any structural interposition, the displacements are measured within 10 mu for linear variations and 0.1 degrees for angular variations. Photogrammetry seems to be more adequate for the study of large range of displacements while holographic and speckle techniques are useful to assess, in the displacements, the part of the disc and the osseous structure deformation respectively.

[Study of the innervation of the spinal ligaments at the lumbar level].

The authors studied the innervation of the human lumbar spinal ligaments on cadaver or surgical specimens. In the ligaments annexed to the neural arch and in the posterior longitudinal ligament were found free-ending fibers and amyelinic perivascular fibers. In the anterior longitudinal ligament, coexisting with perivascular fibers were found encapsulated corpuscular formations on the ventrolateral aspect of the junction between the intervertebral disc and vertebral body. These findings comfort the role of the anterior longitudinal ligament in proprioception essential both in static and dynamic function of the spine.

[Anatomic and physiologic comments concerning the innervation and function of the omohyoid muscle in man].

Electrophysiological studies of the rather strange, enigmatic, likely vestigial omohyoid muscle led the authors to point out the dual nature of its two bellies. Electromyographically, the inferior belly with a nearly constant activity may be opposed to the superior belly with intermittent activity. Motor nerve stimulation combined with electromyographic study demonstrated the superior belly to be supplied by the ansa cervicalis while the inferior belly is supplied by the accessory nerve. Based on these findings, anatomical studies conducted with histological examination were consistent with this double innervation.

[Anatomic study of a omphalosite monster].

The authors report the main anatomical features of a twin holoacardius amorphus monster. Diagnosis of the abnormality was assured by echography at the end of a "normal" gemellary pregnancy. Echograms were consistent with the diagnosis of "amorphus monster" and this was supported by dissection. The caudal extremity of the fetus was clearly identified by the presence of recognizable lower limbs in spite of the several abnormalities of the pelvic area. The cephalic extremity was characteristic of the malformation. Examinations of visceres allowed to precisely identify digestive structures such as intestinal loops (with disseminated atresias). It could not be find any kidney structure. Medially, a small rounded mass was observed and could be identified as hypoplasic cardiac structure. Other main anatomic features consisted of an enormous liquid-filled cavity largely communicating with both the lower part of the neural tube and the basis of the cranium. The placenta was unique and two umbilical with several and large anastomotic by-passes were increased from it.

[Unusual late disclosure of left congenital diaphragmatic hernia].

A posterolateral hernia through Bochdalek foramina was discovered in a 27 months old child under unusual circumstances. During lifting an heavy weight, migration occurred of the abdominal content through the foramina into the left thorax. The size of the pleuroperitoneal communication was well demonstrated by peritoneography. Possible rupture of a diaphragmatic relaxation was eliminated on findings at surgery. Reconstructive surgery led to an uneventful recovery which is the rule in this type of late-discovered hernia.
