[Wandering spleen torsion].

The ectopic spleen characterizes for absence of its suspensory ligaments and a long pedicle that are predisposed to complicate it for a torsion with commitment of the venous drainage at first and arterial at a later time himself, producing increase of its volume and infarct. This anomalous situation, it can be had to a congenital malformation of the development of its suspensory elements and fall toward the inferior abdomen or else to an inferior growth of the mesodermic yolk of that this organ originates itself. The suitable treatment is the laparoscopic splenopexy, but when it exists infarction, it is no possible avoid the splenectomy.

[Comparison of prosthetic materials for abdominal wall reconstruction. Experimental study].

To repair large abdominal deficiencies, either congenital of acquired, occasionally serious problems show up where obtaining the ideal material is concerned, in those cases where autological tissue in the right size can not be found. In this sense materials like silver, steel and tantalium darning have been used, as well as many other synthetic tissues and non porous materials like silastic. During this same period, prosthesis of reabsorbing materials have been developed and used. We present a experimental work in which we compare four prosthesic materials as there are Marlex, Silastic, polyglycolic acid and lyodura, from the clinical, biological and histopathological point of view, distinguishing the ideal material in definite pathologies.

[Vascular sutures using polyglycolic acid in growing arteries. Experimental study].

Vascular anastomoses, carried out in a growing vessel, have certain peculiarities, since with the development of the artery a stenosis may remain in the suture zone which can compromise its success. We believe that the suture material should be absorbable. We carried out an experimental study in which we performed 18 anastomoses of the femoral artery in dogs using 5/0 polyglycolic acid sutures and vascular microsurgery technique. In no case, on reoperating, did we find the existence of stenosis, granuloma, false aneurysm, or disruption. Polyglycolic acid begins to be reabsorbed after one month of evolution, and after two months the reabsorption is almost total. Biological tolerance is optimal.

[Eosinophilic pustular folliculitis (Ofuji syndrome)].

The first observation in Occident of "eosinophilic pustular folliculitis (Ofuji)" is reported. The condition is characterized by pruritic follicular sterile papulopustules on indurated erythematous plaque in the face. They extended centrifugally and the plaque proceeds with remission and exacerbations with leukocytosis and numerous eosinophils. Histological features are pustular folliculitis from the ostium to the sebaceous gland, chiefly composed of polymorphs and many eosinophiles. The treatment are corticosteroids by long-term. It is the first case studied by electron microscopy.

[Ultrastructural study of chronic gastritis].

A study of gastric biopsies with optical and electronical microscope from patients with gastritis in different stages of evolution was realized. The ultraestructural results consist in phenomenal alterations at the epitelium level, apparition of bodies of mielinic aspects in the inside of the Oxintcs cells, reduction of the number of this and the peptic cells and even the disappearance of the last. There is an increase of the mucous cells with mitotic changes, notable hyperplasia of the arget cells and intestinal metaplasia in the advanced cases. In the stroma is demonstrative the infiltration of plasmatic cells having a endoplasmatic reticule in different stages of activity, linphocytes and macrophagous full of primary and secondary lysosomas. A very important fact is the increase of the argentofilous cells and its probably relation with the appearing of the gastritis. The presence of the plasma cells and lynphocyts mark the role that takes the immunitary reaction in this process.

[Nerve endings in cryptorchid testicles].

The authors have carried out an optic and ultrastructural study of cryptorchidic testicles, confirming classical observations, but calling the attention towards the existence of an increased number of nerve endings in the cryptorchidic testicles in relation to those which have descended, and pointing out the characteristics of these endings and the regressive changes which they undergo.
