Endoscopic axillary breast augmentation combine advantages against few inconvenients. The authors discribe the surgical endoscopic technique and the medical patient management. A study on 48 patients shows the efficiency on quick professional activity (3 days) thanks to the control of inflamatory syndrom with a quick procedure and perioperatoire treatment.
The anatomy give a description of the fixation of breast ligaments, on submammary fold, on the vascularisation of the areola-nipple complex and the surgical consequence on sensibility. The innervation areola-nipple complex comes from the 4th lateral cutaneous branch. The sensitive troubles are frequent but compensed by the sensual gratification of the breast. Skin incisions have been analyticly study. Periareolar incision is less pratice than submammary or axillary incision. The concept of adequation parenchyma-implant is fondamental however the pocket is pre- or retropectoral.
Laboratories propose a large variety of mammary implants, in which the multiplicity makes it difficult for the surgeons to choose. The objective of this work was to analyze the various features of the implants proposed by manufacturers, in particular the characteristics of the shell, the specificities of the filling, and the morphology of the implants. Nine laboratories sell ten brands of mammary implants on the European market. The laboratories are: Arion, Eurosilicone, Inamed Aesthetics, Mentor, Nagor, Perouse Plastie, Poly Implants Protheses, Polytech Silimed and Sebbin. All laboratories propose smooth or textured surfaces on the shell. Only one laboratory uses a surface covered by micropolyurethane foam. The fillings consist of a saline solution or a silicone gel. One laboratory provides a filling with hydrogel containing carboxymethylcellulose. The forms suggested are round or anatomical. The various models propose a variation on the projection for the round implants and a variation on the height for the anatomical implants. Analysis of the different catalogues makes it possible to underline the lack of precision in the terms of usage, in particular for the description of the form and the texture. It is unfortunate to have very little technical information and no clinical or biological information imposed by the European standard EN 12180. This prevents the surgeon from making his choice according to the real quality of the implants.
The aim of this paper is to evaluate the so-called "American" injectable collagen, produced since 1975 by Collagen Corporation. Main interest of that work concerns an actual follow-up on millions of patients, treated since 25 years, with more than 280 clinic studies published throughout international literature. Everybody knows that--in human therapeutic--a very long follow-up and a great number of patients is a warranty for a complete security. This Collagen is natural, extracted from bovine dermis; this is the first "true cosmetic drug". Therefore, rigorous practice conditions have to be respected.
INTRODUCTION: Longitudinal melanonychia is a diagnostic and treatment problem for the surgeon. Fear of melanoma most frequently leads to total excision of nail bed, matrix and plate. METHOD: Twenty two patients, aged from 7 to 77, were operated on from 89 to 98 in our department, using different techniques (total matrix biopsy, total excision of melanonichia with direct suture, Schernberg flap). RESULTS: Thumb and index are predominant locations (11 out of 16). No malignant lesions were found histologically. Aesthetic sequellae were frequent and directly linked to the width and location of the melanonychia. Limited matrix biopsy produce the best aesthetic result. DISCUSSION: Malignant lesions are rare and our series is short. Therefore an additional multicentric study is required. Our choice is to make a limited matrix biopsy in the first place with a minimal aesthetic prejudice. Histology determines the treatment choice: excision or follow up.
Although a regulation has been in force in Israel since 1930 which committed the communities to provide for knackers' yards, until some years ago packs of jackals took care of the carcass disposal. Owing to the increase of large slaughter houses for fowl some rendering plants were also erected, which however, eliminated only the waste from these plants. For this reason the government decided to build rendering plants on the European pattern and to legislate pertinent veterinary acts. In Israel 20,000 tons fish-meal is imported annually, worth millions of dollars for feeding purposes, while no attention is as yet being paid to the processing of the national raw materials.
