Experimental cardioplasty using the latissimus dorsi muscle flap.
This study was undertaken to examine the possibility of using the latissimus dorsi muscular flap, divided in two parts thus covering the surfaces of the heart, and inserting it into the thoracic cavity by means of a segmental resection of the second rib. After cadaver case studies, 15 operations were performed on 5 Beagle dogs. The first group of 5 operations consisted of a latissimus dorsi flap graft over the heart. The second group and third group of operations (3 and 6 months later) consisted of reoperating for muscular and cardiac biopsies and electrical stimulation tests on the heart-muscle complex. The latissimus dorsi flap provided a sizable mass of contractile tissue. The haemodynamic studies showed no compressive or constrictive phenomenon of the muscle on the heart and revealed the preservation of an appropriate cardiac output for short intervals of time (2 hours), through phasic electrostimulation of the flap. The histopathological studies showed conserved muscular structure. The technical feasibility, histological adaptability and electrophysiological properties of this muscular flap makes it appropriate to develop a functional stimulation programme and perhaps adequate for the treatment of dysplasic, ischemic, tumoral and other acquired or congenital myocardial diseases.
[Veins and cellulitis].
There is no relation between what French women call "cellulitis" and the venous problems of genetic origin. It may be that cellulitis is the name given to those extra kilos, to mild obesity, to fatty deposits on the thighs and buttocks (sub-trochanteric and crural steatomeries: "jodhpurs"); the point is that cellulitis is apparent, either immediately or on pinching the skin, as an orange-peel pitting. This problem exteriorises the lobular structure of the surface fat. This derives from excessively large lobules, cutaneous relaxation, or excessive pressure on the walls separating the lobules into compartments. Slimming reduces the large areas of deposit at the base of the buttocks. Musculation of the thighs can improve their appearance. More people think they have cellulitis than are really afflicted with it; this is just one of the many deceptions associated with it.

[New emergency hand surgery (author's transl)].
Injured hands may now be divided into two categories: those in which revascularisation by suture or bypass is necessary as an acute emergency and those in which classical reparative surgery suffices. As far as the first category is concerned, those who first see such patients should undertake the vascular repair but also all the others, if this is possible and desirable, or refer the injured individuals to a specialised centre. The prodigious development of microsurgery and its teaching to hand surgeons should soon make it possible for all injured patients to derive full benefit from this revolution. However, the indications must be perfectly defined in order to avoid the creation of handicapped patients and useless increase in surgical expenditure.

[Microbial diffusion and antibiotherapy].
Cleaning leg ulcers depends on tissular and microbial enzymes, the production of which depends on good vascularization. When an aetiological treatment is started, the microbes ensure sufficient cleaning, leading to granulation and epidermization. Antibiotherapy is pointless. Sometimes it can be detrimental, replacing a natural growth with alien strains which cause diffusion. Very exceptionally, a short course of antibiotherapy may be necessary to cope with signs of diffusion, usually signifying a Group A streptococcal infection, with seasonal recrudescence. The Blue Pus Microbe has no special pathological significance. It merely indicates that the case has become chronic.
