Identification of a Peptide Produced by Bifidobacterium longum CECT 7210 with Antirotaviral Activity
2016
Rotavirus is one of the main causes of acute diarrhea and enteritis in infants. Currently, studies are underway to assess the use of probiotics to improve rotavirus vaccine protection. A previous work demonstrated that the probiotic strain Bifidobacterium longum subsp. infantis CECT 7210 is able to hinder rotavirus replication both in vitro and in vivo. The present study takes a systematic approach in order to identify the molecule directly involved in rotavirus inhibition. Supernatant protease digestions revealed both the proteinaceous nature of the active substance and the fact that the molecule responsible for inhibiting rotavirus replication is released to the supernatant. Following pur…
Selection of New Probiotics for Endometrial Health
2019
Microbiota is a crucial player in gynecologic health, in which bacteria can shift to a dysbiotic state triggering a pathogenic process. Based on an ecological understanding of the problem, the aim of this study is to select a potential probiotic strain to improve female reproductive tract based on its capacity to initially lower pH and to promote the reduction of pathogenic bacteria. Based on this rationale, strain Lactobacillus rhamnosus BPL005 was initially selected for its capacity to reduce in vitro pH levels and produce organic acids. Subsequently, strain L. rhamnosus BPL005 (CECT 8800) was demonstrated to have a protective role on endometrial infections in an in vitro model of bacteri…
Analysis of the morphology and composition of tooth apices apicectomized using three different ablation techniques.
2011
Objectives: To investigate apicectomies performed using burs, a CO2 laser or an Er:YAG laser and to evaluate the following aspects: morphology of apicectomized surfaces, presence of failures at the dentin/obturation material interface (marginal fit) of the apical portions of the root canals, and the proportions of chemical elements in the apicectomized surfaces. Study design: Twenty-four teeth were divided into three groups of eight and each group underwent apicectomy by one of three different ablation techniques: bur, CO2 laser or Er:YAG laser. The morphology of the apicectomized surfaces was then analyzed using scanning electron microscopy and their chemical composition was analyzed by en…
Clinical follow-up after surgery of lumbar disc prolapses. A critical analysis.
1990
A retrospective clinical study was made on 987 patients with lumbar disc disease treated by discectomy. All patients had been operated on in the Department of Neurosurgery (University-Hospital Mainz). 545 patients were males, and 442 females (1.2:1). Patients in the 4th decade of life were affected most often (33.5%). Perioperative complications occurred in 5.4%, with discitis as the single major complication (1.9%). 83% of all patients who underwent discectomy could return to their normal occupation.
Treatment of injuries to the inferior alveolar nerve after endodontic procedures.
1998
Overextension of filling material into the mandibular canal after root treatment in the lower jaw is a rare but serious complication. Mechanical compression, chemical neurotoxicity and local infection may cause irreversible nerve damage. A report on 11 patients with neurological complaints of the inferior alveolar nerve after endodontic treatment is summarised. The neurological findings are dominated by hypaesthesia and dysaesthesia. Half of the patients reported pain. Hyperaesthesia is found much more rarely. Nearly all the patients had a combination of one or more symptoms. Initial X-rays showed root filling material in the area of the mandibular canal. Nine cases were treated with apicec…
Dysphagia Prevention in Anterior Cervical Discectomy Surgery: Results from a Prospective Clinical Study
2019
Background: Dysphagia is a common complication after anterior cervical discectomy surgery (ACDS). Recent studies have shown that reducing the endotracheal tube cuff pressure, local irrigation with methylprednisolone, and minimizing the pharynx/esophagus retraction can decrease the incidence of postoperative dysphagia after ACDS. This is the first study assessing the efficacy of all these 3 measures simultaneously. Methods: This prospective study included 35 patients (group 1) who underwent ACDS with the adoption of all the 3 preventive measures. Group 1 was compared with a homogenous group of 35 patients who underwent regular ACDS (group 2). Postoperative dysphagia and odynophagia were eval…
Clinical and radiological features of hybrid surgery in multilevel cervical degenerative disc disease.
2015
Purpose: Although several studies have established the safety and efficacy of cervical disc arthroplasty (CDA) as compared to anterior cervical discectomy and fusion (ACDF), few studies have investigated the role of hybrid surgery (HS) that incorporates ACDF and CDA techniques in multilevel cervical degenerative disc disease (MLCDDD). Methods: This prospective study enrolled patients with MLCDDD who underwent HS. Twenty consecutive patients who underwent HS were compared with patients who underwent ACDF and CDA at the same level of surgery. Patients were followed up for more than 2 years. Intraoperative parameters, clinical features and outcome scores were recorded. Radiological assessments…
Evaluation of appendicitis risk prediction models in adults with suspected appendicitis.
2019
Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (pro…
Periapical surgery of maxillary posterior teeth : A review of the literature
2006
En los últimos años, la cirugía periapical ha evolucionado gracias a la incorporación de avances diagnósticos y técnicos. El objetivo del presente artículo es realizar una revisión bibliográfica de los trabajos publicados sobre cirugía periapical en los dientes antrales; hemos revisado el Medline y las revistas españolas de Odontología desde 1974 hasta el 2003. Comentamos la anatomía del seno maxilar, el diagnóstico de las lesiones periapicales y la relación del seno maxilar con los dientes antrales; también la técnica quirúrgica, sus consideraciones especiales, y el pronóstico de la cirugía periapical en estos dientes. Los trabajos recientes plantean que la proximidad de los dientes antral…
Sealing ability of five different retrograde filling materials.
1996
The sealing ability of Amalgam, Harvard-Cement, Diaket, gold-leaf, and Ketac-Endo as retrofilling materials was investigated. Paper cones were fixed with Harvard-Cement in the instrumented roots of 100 extracted human incisors. Apicectomy was performed and a 2-mm-deep retrograde cavity was prepared. Teeth were assigned to five groups (n = 20); each group received a different filling material. Surfaces of the roots were isolated with nail polish. Teeth, were stored in 1% methylene blue dye for 72 h. Roots were sectioned, and the depth of dye penetration was evaluated through a stereomicroscope. Retrofills with Ketac-Endo showed significantly less leakage compared with amalgam. There was no s…
