Arteriovenous fistulas for hemodialysis created using a long-term absorbable suture: a safe solution and a measure to minimize myointimal hyperplasia.

BACKGROUND/AIMS: The goal of the therapeutic management of patients affected by end-stage renal disease (ESRD) is to maintain the vascular access (VA) as long as possible. Myointimal hyperplasia development in the vascular walls of arteriovenous fistulas (AVFs) is considered one of the most important factors responsible for procedure failure. These alterations could be linked to hemodynamic changes in the anastomosis and to the presence of the surgical suture itself. We report our preliminary experience, discussing the use and the possible benefits of an absorbable suture in polyglycolide trimethylene carbonate (PTC) in AVF creation. METHODS: Seventy-four AVFs were created as primary access for hemodialysis (HD), using PTC, over 4 years. Age, gender, ESRD etiology, artery and vein preoperative diameters, AVF survival outcome, and the number of AVFs created per year were recorded. The Kaplan-Meier method was used to analyze AVF survival rates. RESULTS: No dehiscences, pseudoaneurysms, or failures in the 'critical' period related to PTC absorption were recorded. Kaplan-Meier analysis was used to evaluate AVF survival; 12-month primary AVF survival (74.33%) and AVF failure (25.67%) rates, 9 'early' (8.22%) and 10 'late' failures (13.51%), and a 360-day mean survival were found. CONCLUSIONS: Our data indicate that PTC, a well known and widely used material for sutures in vascular surgery, is safe and effective in AVF creation. Potential advantages of PTC sutures are represented by a reduced myointimal hyperplasia formation in the AVF vascular walls, prolonging the AVF lifespan and avoiding re-interventions.

[Pregnancy and breast-feeding: developmental stages of mother-child bonding].

Several authors, confronting the mother-child relationship during pregnancy and breast-feeding, talk about an uterine and extra-uterine symbiosis. In this way, one bypasses the fact that the so called unions end with the processes of separation constituted by the birthing/birth (by the termination, that is to say, of the first maternal nurturing (that of placenta) as well as by the termination of the second maternal nurturing (that of the individual breast-feedings). The careful observation of these unions demonstrates that they coexist and they imply equilibrium through the processes of separation that not only allow a partial autonomy of the developments of mother and child, but also make room for the detachments represented by the birthing/birth and by the end of the individual breast feedings. The author is trying to illustrate some physiological and pathological equilibrium between these tendencies towards reciprocal dependence and reciprocal mother-child autonomy.

[Composite materials in pedodontics].

A brief account is given of the features of 1st and 2nd generation compounds and their clinical applications. Reference is made to many years of personal experience in an assessment of their long-term results.

[Supernumerary teeth in the deciduous dentition].

The Authors presented sovrannumeraries (S) teeth in primary dentition, and the pedodontic, surgical and orthodontic problems. Semeiotics signs, and X Ray suggested, are described. All the types of S. teeth are showed: supplementaries, conoides, tuberculates and infundibuliformes. For every type characteristics, problems and surgical timing are described. Tuberculates and infundibuliformes teeth are the most dangerous for the permanent teeth interrupted: eruption delay, dilacerations, impactions, fusion, follicles, diseases, are reported. The direction of the growth of S. teeth must be analyzed. If the direction is external the timing of surgery is very important. Finally the Authors emphasized the role of cooperation of pedodontist, with oral surgeon and orthodontist for to obtain good results.

[Epidemiological studies of malocclusion in the school population of a mountain district].

Authors report the prevalence of malocclusions in 2227 school children of a mountain district. The frequency of this pathology is very high especially in the first and third class of Angle's classification. The prevalence in this sample results also statistically higher than in a sample of school children of the plane in the province of Pavia, particularly in six years old children and in the Angle's classes we have mentioned. Authors remember the importance that preventing medicine, through sanitary education, can play in the pathology depending on personal behaviours.
