Objective Computer-aided-surgery in ENT surgery is mainly used for sinus surgery but navigation accuracy still reaches its limits for skull base procedures. Knowledge of navigation accuracy in distinct anatomical regions is therefore mandatory. This study examined whether navigation accuracy can be improved in specific anatomical localizations by using hybrid registration technique. Study design Experimental phantom study. Setting Operating room. Subjects and methods The gold standard of screw registration was compared with automatic LED-mask-registration alone, and in combination with additional surface matching. 3D-printer-based skull models with individual fabricated silicone skin were u…

Population-based cancer registries in Spain and their role in cancer control

2010

Abstract Population-based cancer registries (PBCRs) are a key element for cancer control. They measure cancer incidence and trends, provide indicators for planning and evaluating cancer control activities, and undertake research. The first two PBCRs in Spain were established in Zaragoza in 1960 and Navarre in 1970, but it was from 1980 to 1995 when most of the existing registries went into operation. Today, 26.5% of the Spanish population is served by a cancer registry. All registries’ quality-control indicators meet the inclusion criteria for comparability and quality of data required by the International Agency for Research on Cancer, and indeed some fulfil most of the excellence criteria…

Adjuvant versus Neoadjuvant Radiochemotherapy for Locally Advanced Rectal Cancer A Progress Report of a Phase-III Randomized Trial (Protocol CAO/ARO/…

2001

The standard treatment for patients with clinically resectable rectal cancer is surgery. Postoperative radiochemotherapy is recommended for patients with advanced disease (pT3/4 or pN+). In recent years, encouraging results of preoperative radiotherapy have been reported. This prospective randomized phase-III trial (CAO/ARO/AIO-94) compares the efficacy of neoadjuvant radiochemotherapy to standard postoperative radiochemotherapy. We report on the design of the study and first results with regard to toxicity of radiochemotherapy and postoperative morbidity. Patients and Methods: Patients with locally advanced operable rectal cancer (uT3/4 or uN+, Mason CS III/IV) were randomly assigned to pr…

Cervical Motion Preserving Procedures (TDR)

2019

Symptomatic cervical degenerative disc disease leading to radiculopathy is a common problem with an incidence of 0.83–1.79 per 1.000 person years. While many episodes of radicular symptoms can be successfully managed by conservative therapy, patients with refractory symptoms or a significant paresis are candidates for a surgical treatment. However, different surgical techniques are available to treat cervical degenerative disc disease, as anterior cervical discectomy without fusion, anterior cervical discectomy with fusion or posterior foraminotomy. Anterior cervical discectomy with fusion as described in the 1960’s (Chap. 3) is currently regarded as the gold standard. Although ACDF provide…

Use of Zoledronic Acid in a Neonate with Subcutaneous Fat Necrosis Complicated with Severe, Refractory Hypercalcemia.

2019

Objective Subcutaneous fat necrosis (SCFN) is a rare condition that may occur in the neonatal period. SCFN is an inflammatory disorder of the adipose tissue, usually found in full-term healthy infants who have a history of intrauterine or perinatal distress. It is usually a self-limited condition; however, in some cases, it can get complicated, leading to severe hypercalcemia that may be life-threatening. Study Design We report and describe a classic presentation of SCFN that led to severe hypercalcemia refractory to standard treatment. The diagnosis of SCFN was made based on the finding of subcutaneous nodules and of hypercalcemia. The serum calcium level reached 16.6 mg/dL. Hypercalcemia…

Complications of harvesting a connective tissue graft from the palate. A retrospective study and description of a new technique

2017

Background Connective tissue graft (CTG) is considered as the gold standard for the treatment of gingival recessions (GR). There are few studies assessing the complications that can arise in the donor site when harvesting a connective tissue graft (CTG) and how the harvesting technique can influence those complications. Material and methods A retrospective clinical study was carried out in order to compare the complications observed in 40 patients with Miller class I, II and III GR ≥ 3 mm, after using the trap-door technique (TD) in the control group and a newly described technique, the "UPV/EHU technique", in the test group. Patients were consecutively allocated to each treatment group. Pa…

Swallowing impairment in neurologic disorders: The role of videofluorographic swallowing study

2018

Patients with neurologic diseases almost inevitably develop various degrees of swallowing disorders during their life. Dysphagia is one of the main negative prognostic factors in this class of patients, leading to severe morbidity (i.e. aspiration pneumonia, dehydration, malnutrition, and life quality deterioration) and to a noticeable increase in public health spending. Videofluorographic swallowing study is considered the gold standard technique for swallowing impairment assessment. It is aimed at early identification of the risk of aspiration, definition of the kind and grade of dysphagia, and an indication to suspend oral nutrition and adopt other feeding strategies, and define when the…

Evaluation of treatment outcomes in a 3 years post-graduate orthodontic program using the peer assessment rating (par)

2014

Objectives: To maintain high treatment quality it is important to evaluate orthodontic treatment results using objective methods. Outcome assessments allow private practitioners and university students to evaluate their results and raise the level of treatment outcomes. The aim of this study was to assess the orthodontic treatment outcome in a post-graduate orthodontics program in the University of Valencia (Spain) and to determine whether the treatment outcome is related to several factors as gender, age at start of the treatment, treatment duration, treatment method, extraction-non extraction treatment and cooperation needed. Material and Methods: A sample of 50 patients treated in the po…

Evaluation of the quality of publications on randomized clinical trials using the Consolidated Standards of Reporting Trials (CONSORT) statement guid…

2011

The main reason for conducting a clinical trial (CT) is to test the effect of a drug or medical procedure to improve treatment of a disease. CTs contribute most when they are rigorously conducted and the results are published adequately. The aim of this study is to assess, using the CONSORT statement guidelines, the quality of reporting of completed CTs conducted at a tertiary hospital to determine which sections of the articles should be improved. CTs published between 2002 and 2008 were identified by searching the MEDLINE and Cochrane Library. Forty of 127 completed CTs were published. There was a marked increase in the number of articles and the quality of the journals that published the…

Comparison of the ability of alternative birthweight and fetal weight standards to identify preterm newborns at increased risk of perinatal death

2013

Objective To compare prediction of perinatal deaths among preterm infants based on fetal weight standards versus a new subpopulation-based birthweight standard. Design Population-based cohort study. Setting France. Population A total of 9100 preterm singletons, born between 24 and 36 weeks of gestation in 2000–09, in Burgundy (France). Methods We first classified all newborns as either small for gestational age (SGA) or not, based on alternative fetal weight or birthweight standards, including a new birthweight standard that excludes infants born to mothers with disease related to the weight of a fetus. Based on discrepancies between the different classifications, we then divided the newbor…
