Tras la 14 ª Conferencia Internacional sobre el SIDA, ¿Cuánto sufrimiento nos espera todavía?

2002

Se tratan de analizar los factores que pueden incrementar o disminuir el sufrimiento de las personas que, soportan o van a soportar las consecuencias emocionales de la infección porVIH y/o de la aplicación o carencia de los tratamientos antirretrovirales disponibles. Su objetivo es conseguir que todos aquellos que practican comportamientos de riesgo, que se infectan con el VIH, que se someten a un tratamiento o no tienen acceso al mismo, así como también sus familiares y los agentes de salud que los atienden, puedan hacer frente a estas realidades al menor coste emocional posible. El mejor camino que nos conduce hacia este objetivo es el counselling.

Small bowel obstruction after laparoscopic gastrectomy: An atypical clinical presentation. Report of a case

2020

Abstract Introduction Postoperative adhesions represent the most common cause of acute small bowel obstruction (80%) and are usually a consequence of abdomino-pelvic surgery performed with open technique. Presentation of case A 45-year-old black man arrived at the emergency room with abdominal pain and distension three months after laparoscopic distal gastrectomy with Roux-en-Y anastomosis performed for benign pyloric stenosis. CT abdominal scan revealed some air-fluid levels in the center of the abdomen with distension of proximal jejunal loops caused by intestinal adhesions. Laparoscopic adhesiolysis was performed to restore the intestinal transit. Discussion The formation of adhesions is…

Attuali orientamenti nella diagnosi e nel trattamento delle aderenze placentari patologiche: la nostra esperienza

2010

The abnormal adherence of the placenta is a disease characterized by an anomalous miometrial infiltration of Chorionic villi. This event blocks the regular detachment of placenta in post partum and sometimes a severe bleeding that causes the urgency of a caesarean section. In the past years the incidence of this pathology has increased to about 1 in 500/600 deliveries. The cause of abnormal adherence of placenta is unknown but there are some risk factors such as prior caesarean sections, women older than 35 years of age and placenta previa. The early diagnosis is very important and it can be done by Eco-Color-doppler (eventually associated with 3d technique) and Magnetic Resonance. Objectiv…

Cubic Microcontainers Improve In Situ Colonic Mucoadhesion and Absorption of Amoxicillin in Rats

2020

An increased interest in colonic drug delivery has led to a higher focus on the design of delivery devices targeting this part of the gastrointestinal tract. Microcontainers have previously facilitated an increase in oral bioavailability of drugs. The surface texture and shape of microcontainers have proven to influence the mucoadhesion ex vivo. In the present work, these findings were further investigated using an in situ closed-loop perfusion technique in the rat colon, which allowed for simultaneous evaluation of mucoadhesion of the microcontainers as well as drug absorption. Cylindrical, triangular and cubic microcontainers, with the same exterior surface area, were evaluated based on i…

Development and Characterization of an Amorphous Solid Dispersion of Furosemide in the Form of a Sublingual Bioadhesive Film to Enhance Bioavailabili…

2017

Administered by an oral route, Furosemide (FUR), a diuretic used in several edematous states and hypertension, presents bioavailability problems, reported as a consequence of an erratic gastrointestinal absorption due to various existing polymorphic forms and low and pH-dependent solubility. A mucoadhesive sublingual fast-dissolving FUR based film has been developed and evaluated in order to optimize the bioavailability of FUR by increasing solubility and guaranteeing a good dissolution reproducibility. The Differential Scanning Calorimetry (DSC) analyses confirmed that the film prepared using the solvent casting method entrapped FUR in the amorphous state. As a solid dispersion, FUR increa…

Water absorption and hydrothermal ageing of epoxy adhesives reinforced with amino-functionalized graphene oxide nanoparticles

2021

Abstract The study is focused on quantitative characterization of water absorption and hydrothermal ageing effects in a room-temperature amine cured epoxy adhesive widely used in automotive, aerospace, construction, and marine industries. Amino-functionalized graphene oxide (mGO) nanoparticles were incorporated into the epoxy (up to 1.72 wt.%) enabled cross-linking reactions and providing high interfacial adhesion, superior reinforcement efficiency and enhanced resistance to hydrothermal ageing of nanocomposites. Anomalous water absorption accompanied by progressive weight loss of samples (down to 7%) is fitted by two-stage models considering additive and coupled contribution from water dif…

Hybrid layers of etch-and-rinse versus self-etching adhesive systems.

2010

Objective: To evaluate the effectiveness in the formation of resin tags, adhesive lateral branches and hybrid layers of five adhesive systems, when bonding to dentine. Material and Methods: Flat dentin surfaces from 25 molars were bonded with several adhesive systems according to the manufacturers? instructions. Composite build-ups were constructed incrementally with Tetric Ceram. The Specimens were sectioned parallel to the long axis. One section was treated with phosphoric acid and sodium hypochlorite in order to reveal the hybrid layer formation. The other section was stored in 30% hydrochloric acid to detect resin tags and adhesive lateral branch formation. Results: The two etch-and-rin…
