Active clinical trials for "Atrophy"

This randomized prospective study was designed to compare the clinical, functional and aesthetic results of two surgical techniques for microsurgical clipping of anterior circulation aneurysms

Bone resorption and atrophy in maxillary posterior region is due to severe periodontal disease and is consequent tooth extractions. Sinus pneumatisation can occur after tooth extraction and alveolar bone loss. Consequently, bone-reducing volume at that region is a great challenge to implantodontists. Sinus lifting surgery have been practiced since 80's and many biomaterials have been used to solve filling issues to maintain the sinus floor lifted in a position that can allow dental implants installation. Bone grafts have shown to be the best choice of filling grafts. Despite autologous bone are the gold standard filling biomaterial it is associates with great mortality and morbidity. So, bone allografts from tissue bank had been shown to be an advantageous alternative. Lyophilized or freeze tissue bone are the most common allografts but literature is poor in randomized controlled parallel clinical trials regarding those filling grafts for sinus lifting. The aim of this study is to perform a randomized controlled clinical trial comparing two bone allografts: lyophilized and freeze bone allografts from human bone tissue bank. The investigators want to verify which one can develop greater osteogenesis, if is there any difference between them regarding the architectural trabeculae formation, if there are different patterns of reabsorption and finally if is there any differences between them regarding primary and lately dental implants stability. To answer those questions the investigators propose firstly, to carry out microtomographic and histological analysis from trephine bone samples after six months of sinus lifting and grafting in healthy participants undergoing osseointegrated dental implants. Secondly, the primary and lately implant stability is going to be achieved employing Resonance Frequency Analysis (RFA).

Atrophic gastritis with hypochlorhydric milieu is a risk factor for gastric cancer. Microbes colonizing the acid-free stomach oxidize ethanol into acetaldehyde, a group 1 carcinogen. The aim is to assess gastric production of acetaldehyde and its inert condensation product, non-toxic 4-methyltiazolidine-2-carboxylic acid (MTCA), after alcohol intake under treatment with slow-release L-cysteine or placebo. Patients with biopsy-confirmed atrophic gastritis, low serum pepsinogen and high gastrin-17 are studied. On separate days, patients will be randomly assigned to receive 200 mg slow-release L-cysteine or placebo, then have intragastric instillation of 15% (0.3 g/kg) ethanol. After intake, gastric concentrations of acetaldehyde, ethanol, L-cysteine and MTCA are analysed for 4 hours. Expected results show mitigated exposure of the gastric mucosa to acetaldehyde.

Rotator Cuff (RC) repair will be augmented with the injection of a human amniotic fluid derived allograft at the repair interface junction. A secondary injection will be administered at the time of repair in the supraspinatus muscle body medial to the musculotendonous junction.

This study will compare clinical and radiographic outcomes of three different treatment modalities for atrophied distal extension maxillary ridges these modalities include Implant retained distal extension RPD Sinus lift and long implant and screw-retained prosthesis Short implant and screw-retained prosthesis

Tissues of the genitals of women are both androgen (testosterone) and estrogen dependent. The clitoris, vestibule, urethra, anterior vaginal wall, peri-urethral tissue, and pelvic floor all depend on androgens for normal function. In addition, the glands, which secrete lubrication during sexual arousal, also require androgens to function. Deficiencies of both estrogens and androgens occur naturally during menopause. Menopause-related deficiencies of these hormones lead to thinning in the tissues of the genital and urinary systems which have been termed Genitourinary Syndrome of Menopause (GSM). Patients with GSM will frequently complain of dryness and/or pain during sexual intercourse. Historically, GSM treatment involved both androgens and estrogens, However, over the past few decades estrogen based therapies have become much more common. More recently, clinical trials have demonstrated that local vaginal dehydroepiandrosterone (Intrarosa®) improves symptoms in menopausal women who have moderate to severe pain with intercourse. Intrarosa® vaginal inserts are a prescription medicine approved by the U.S. Food and Drug Administration (FDA) used in women after menopause to treat moderate to severe pain during sexual intercourse caused by changes in and around the vagina that happen with menopause.

The aim of this study is primarily to investigate the performance of Celegyn®, a hyaluronic acid-based vaginal cream (CE marked 0546 medical device), enriched with plant-based ingredients, in comparison with placebo, in promoting vaginal health in adult woman reporting symptoms of vulvovaginal atrophy - VVA (or atrophic vulvovaginitis)

Guided bone regeneration (GBR) is a surgical technique that uses barrier membranes to promote osteoblast cells proliferation and exclude other cells such as epithelium and connective tissue cells. GBR is often combined with bone grafting procedures. Using Absorbable membranes like collagen membrane will reduce treatment time by decreasing need for second surgery

30 postmenopausal females with senile vaginitis will be enrolled with score of <15 on the Gloria Bachman Vaginal Health Index (VHI) intramucosal injections of PRP will be adminstered and perform clinical evaluations at 0, 1, 3, and 6 months.

this study is aiming to Assess postoperative complications and bone quality and quantity in augmentation of horizontally atrophic maxillary ridge using a 1:1 mixture of autograft and xenograft particulate bone covered with collagen membrane with the new Sausage technique™ versus using the same mixture covered with titanium mesh.
