The fate of implant after endoscopic injection of dextranomer/hyaluronic acid in vesicoureteral reflux: time to partial reabsorption and stabilization

2020

Summary Background/introduction Vesicoureteral reflux (VUR) potentially leads to renal damage, scarring, and eventually end-stage renal disease. Endoscopic treatment is well tolerated in children, it has reduced costs, and it effectively prevents urinary tract infections (UTIs), while avoiding long term antibiotics use. Objective With the aim to investigate the time needed to reach the stabilization of the dextranomer/hyaluronic acid (Dx/HA) implants and to identify cut-off heights to ensure the success of the procedure, the authors analyzed ultrasonographic (US) intra-operative appearance of the mounds following endoscopic treatment for VUR and repeated the measurements during serial posto…

Hyaluronic Acid in the Treatment of Pain Due to Knee Joint Immobilisation

1995

This open, randomised study was carried out in order to evaluate the safety and efficacy of a course of 5 intra-articular injections (one per week) of hyaluronic acid (HA), administered to patients with pain and joint stiffness resulting from immobilisation of the knee in a plaster cast. The study was made in comparison with an untreated control group. 30 patients of both genders, aged between 18 and 65 years, immobilised in a plaster cast for at least 20 days and presenting with pain and reduced mobility, were included in the study. The results of the study show that, in comparison with the control group, treatment with HA produced a more rapid and effective reduction in pain and increase …

Ibandronic acid subsequent to raloxifene: Effect on bone metabolism and on cardiovascular risk factors

2015

s / Maturitas 81 (2015) 144–190 161 Materials andmethods: This randomized double-blind clinical trialwas carried out inAhvaz (Iran) fromAugust toDecember 2010. Forty postmenopausal women with symptoms of vaginal atrophy were randomly allocated to two groups to take vaginal suppositories of either 5mg hyaluronic acid sodium salt (n=20) or 1mg vitamin E (n=20) for 8 weeks. The symptoms of vaginal atrophy were evaluated by a self-assessed 4-point scale and the composite score was determined as none, mild, moderate, and severe in four periods. Results: The results showed that the symptoms were relieved significantly in both groups (P<0.001). The relief of symptomswas significantly superior in t…

A hyaluronic acid/cyclodextrin based injectable hydrogel for local doxorubicin delivery to solid tumors

2020

Localized delivery of anticancer drugs is often the most useful therapeutic approach for the treatment of solid tumors. The use of injectable polymeric systems that maximize drug concentration in the proximal area of the tumor represents an extremely advantageous therapeutic strategy. Here, the development of an injectable in situ forming hydrogel was accomplished by exploiting the azo-type Michael reaction between an amine derivative of hyaluronic and vinylsulfone functionalized -cyclodextrins complexing doxorubicin. This injectable system can be easily prepared and administered with timelines compatible with normal operating room procedures, as demonstrated by rheological tests. In vitro…

Safety of intra-articular hip injection of hyaluronic acid products by ultrasound guidance: an open study from ANTIAGE register.

2013

Abstract. – OBJECTIVE: We developed a standardized technique for ultrasound guided intra-articular injection of the hip joint with the purpose of extending routine intra-articular injection of hyaluronans and steroids to the hip, as commonly used in the knee. In this article we report the safety of this technique in an extended series of patients. PATIENTS AND METHODS: Patients were injected supine with an anterosuperior approach under ultrasound guidance. The Us probe is applied with a target device for biopsy. RESULTS: The standardised technique was used to inject 1906 patients with 4002 injections of hyaluronan products over a four-year period. The treatment was well tolerated with few, …

New Modalities in Knee Osteoarthritis Treatment Using Autologous Bone Marrow-Derived Mononuclear Cells

2018

Abstract The clinical effects on knee osteoarthritis (OA) symptoms and tissue structure were evaluated after bone marrow-derived mononuclear cell intraarticular injection. A group of 32 patients with 34 knee joints in stage II–III osteoarthritis were treated by intraarticular injection of mononuclear cell suspension. Clinical results were obtained by KOOS (Knee Osteoarthritis Outcome Score) and KSS (Knee Society Score) scores during a 12 months follow-up period. Radiological evaluation was performed using magnetic resonance imaging. A comparison with a control group of 28 patients treated with routinely used three hyaluronic acid intra-articular injections was made. No adverse effects were …

Hip viscosupplementation under ultra-sound guidance riduces NSAID consumption in symptomatic hip osteoarthritis patients in a long follow-up. Data fr…

2011

Introduction: Non-steroidal anti-inflammatory drugs (NSAIDs) consumption is strictly related to a high gastrointestinal and cardiovascular mortality and morbidity rate. Osteoarthritis Research Society International (OARSI) recommendations in patients with symptomatic hip or knee OA stated that NSAIDs should be used at the lowest effective dose but their long-term use should be avoided if possible. OARSI guidelines for the treatment of the hip OA include the use of viscosupplementation, which aims to restore physiological and rheological features of the synovial fluid. Objective: Aim of this multicentric, open and retrospective study is to investigate if NSAID consumption may be reduced by t…

Scientific evidence on the usefulness of intraarticular hyaluronic acid injection in the management of temporomandibular dysfunction

2010

Abstract Hyaluronic acid (HA) is found in high concentrations in cartilage and synovial fluid, and is an important component of the extracellular matrixes ? exerting joint lubrication and buffering actions thanks to its viscoelastic properties. The present study examines the scientific evidence found in the current literature on the usefulness of the intraarticular injection of HA in patients with temporomandibular dysfunction. A literature search was made up until May 2008 in the following databases: PubMed / MEDLINE. Of the articles found in the literature, the present review included 18 relevant studies on the application of HA in the temporomandibular joint (TMJ). The quality, level of …

Hyaluronan‐coated poly(propylene imine) dendrimers as biomimetic nanocarriers of doxorubicin

2022

A coating technology based on low molecular weight hyaluronic acid (HA) and ferulic acid (FA) was applied to the coating of low generation poly(propylene imine) dendrimers through a biocompatible hexa(ethylene glycol) spacer. The ensuing HA-FA-HEG-PPID dendrimeric materials showed interesting loading capability (between 7.65% and 9.08%) regarding anticancer agent doxorubicin, and their interactions with the drug appeared to hamper the drug release in the physiological environment. Thus, the stable nanostructured loaded delivery systems were able to internalize into cells expressing the HA receptor CD44 and to demonstrate high cytotoxicity comparable to that shown by equivalent amounts of fr…
