A simple method to treat post-kydney transplantation lymphocele
OBJECTIVE: To describe our experience with ultrasonic-guided instillation of povidone-iodine to treat post-kidney transplantation lymphocele. Patients and methods. We studied the safety and efficacy of this procedure for treatment of lymphocele in 6 male kidney transplanted recipients in which we assisted a progressive increase of creatinine and urinary proteins levels and color-Doppler ultrasonography demonstrated an increase (25,4%) of index of resistence (IR) Using eco-colorDoppler, the related-graft lymphocele location and the distance to the anterior abdominal wall were determined; then, a radiopaque double-lumen catheter was used to instillate 5% povidone-iodine 10 ml. Results. Percut…
Obtaining mesenchymal stem cells from adipose tissue of murine origin: Experimental study
Stem cells have a key role in regenerative medicine and tissue engineering. Although not immortal, they are able to expand manyfold in culture retaining at the same time their growth and multilineage potential. They also show a migratory capacity when transplanted systemically in animal model with injuries. Thanks to their properties and their plasticity stem cells are of great importance since they can be used as a tool for repair damaged tissues and organs. Mesenchymal stem cells, in particular, have the ability to differentiate into lineages of mesodermal tissues, such as skeletal muscle, bone, tendons, cartilage, and fat under appropriate culturing conditions. Recent evidence suggest th…
Enteral nutrition: Our experience with percutaneous endoscopic gastrostomy (PEG) and revision of literature
Enteral nutrition (EN), as parenteral nutrition (PN), can be used in cases of patients whose medical conditions prevent the intake of food by mouth; unlike PN, EN keeps the functionality of the digestive tract and it makes home management of patients easier. However, the experience and literature have documented a number of serious complications, fortunately rare, which depend on the methods used in EN realization. We report in this paper our experience in 44 cases of percutaneous endoscopic gastrostomy (PEG), concluding that it is a safe and complications-free procedure. We believe that a nutritional intervention is indicated when, improving nutritional status, patients can obtain a better…
Feeding the brain: the importance of nutrients for brain functions and health
‘We are what we eat’, said the philosopher Feuerbach. In fact, the quality of the food we eat affects our mind as well: the brain, which represents 2% of our body weight, consumes about 20% of the calories we eat each day. Follow a few rules could therefore help to feed properly our brain, so it works to the best of its ability. It is important to know properties of foods especially regarding their aminoacidic composition because aminoacids are components of neurotransmitters, molecules needed for brain transmission and function. It is also possible to choose specific food to prevent or support different diseases that affects nervous system.
Biocompatibility and biodegradability of electrospun phea-pla scaffolds: Our preliminary experience in a murine animal model
We obtained a nano-fibrillar scaffold starting from a polymeric solution which, through electrospinning, gave a biodegradable material with optimal mechanical features and the capacity to allow cell adhesion. In this paper we report the in-vivo application on a murine animal model of two electrospun biodegradable materials, specifically designed to create tubular structures. In one case PHEA-PLA was co-spun with silk fibroin (Fibro-PHEAPLA) by a parallel electrospinning process to obtain a scaffold with two different polymeric fibers. In the other case, PHEA-PLA was mixed with polycaprolactone (PCLPHEA-PLA) to obtain a hybrid fibers scaffold. The in-vitro assay showed fibroblast colonizatio…
A case report of a difficult dissection of the iliac vessels conducted by means of the harmonic scalpel during a kidney transplantation
Background. The “difficult” preparation of iliac vessels in the kidney transplant recipient caused by a perivascular fibrosis with satellite lymphadenopathy is sometimes burdened by post-transplant complications (lymphocele, seroma and hematoma). Both iliac vascular adhesions and satellite lymphoadenopaty are often due to reiterate femoral cannulation aimed to hemodialysis. Patients and Methods: The case report concerns a 60 years old female uremic patient, on dialysis for about 4 years with perivascular fibrosis and pelvic lymphadenopathy caused by bilateral femoral artery catheterization. In the course of kidney transplant, preparation of the iliac vessels was performed by ultrasonic scal…
