Screw fixation of radial head fractures: Compression screw versus lag screw—A biomechanical comparison

2009

Abstract Introduction Secondary loss of reduction and pseudarthrosis due to unstable fixation methods remain challenging problems of surgical stabilisation of radial head fractures. The purpose of our study was to determine whether the 3.0 mm Headless Compression Screw (HCS) provides superior stability to the standard 2.0 mm cortical screw (COS). Materials and methods Eight pairs of fresh frozen human cadaveric proximal radii were used for this paired comparison. A standardised Mason II-Fracture was created with a fragment size of 1/3 of the radial head's articular surface that was then stabilised either with two 3.0 mm HCS (Synthes) or two 2.0 mm COS (Synthes) according to a randomisation …

Minimally invasive plate fixation in femoral shaft fractures

1997

Bridge-plating with its advantages in terms of vascularity and bone healing is a well established procedure today in the treatment of comminuted femoral fractures. Bridge-plating means that the fracture site is not interfered with during the operative procedure. This paper introduces a surgical technique in which the plate is inserted through isolated proximal and distal incisions only, behind the vastus lateralis. Alignment is secured by the plates, the fracture site remains untouched, fixation and screw insertion is restricted to the proximal and distal main fragments. Longitudinal femoral fractures extending right into the trochanteric and or condylar areas are the main indication for mi…

18F-FDG PET/CT in cardiovascular infection and inflammation.

2021

The diagnosis of cardiovascular infection and inflammation by [18F]FDG PET/CT in Nuclear Cardiology is of growing interest, because with respect to echocardiography this technique has improved the certainty in the diagnosis of infective endocarditis in patients with prosthetic valves, the increasing number of patients with implantable cardiac devices because of the progressive ageing of the population, as well as in patients with suspected large vessel vasculitis. All are serious clinical situations which require correct diagnosis and appropriate treatment as soon as possible, because they can cause severe complications, high mortality and also increased health care costs. We review the use…

Chelation of synaptic zinc induces overexcitation in the hilar mossy cells of the rat hippocampus.

2004

Complete removal of synaptic zinc by the chelator dietyldithiocarbamate (DEDTC; 500 mg/kg i.p.) in rat was followed by convulsive behaviour including wet dog shakes alternating immobility. Histological analysis 1 day after DEDTC administration detected expression of heat shock protein in the hippocampus restricted to hilar cells. These cells colocalize the marker for neurons and the glutamate receptor GluR2/3 showing that they are excitatory neurons. Additionally, they projected to the contralateral dentate gyrus. Therefore, they correspond to hilar mossy cells. These data show that the synaptic zinc has a role in normal hippocampus avoiding overexcitation, that would impair functionality e…

Nonalcoholic fatty liver disease, association with cardiovascular disease and treatment. (I). Nonalcoholic fatty liver disease and its association wi…

2016

Non-alcoholic fatty liver disease (NAFLD) comprises a series of histologically lesions similar to those induced by alcohol consumption in people with very little or no liver damage. The importance of NAFLD is its high prevalence in the Western world and, from the point of view of the liver, in its gradual progression from steatosis to steatohepatitis, cirrhosis, and liver cancer. During the last decade it has been observed that NAFLD leads to an increased cardiovascular risk with acceleration of arteriosclerosis and events related to it, being the main cause of its morbidity and mortality. This review, updated to January 2016, consists of two parts, with the first part analysing the associa…

Minimal Reporting Standards for Active Middle Ear Hearing Implants.

2017

There is currently no standardized method for reporting audiological, surgical and subjective outcome measures in clinical trials with active middle ear implants (AMEIs). It is often difficult to compare studies due to data incompatibility and to perform meta-analyses across different centres is almost impossible. A committee of ENT and audiological experts from Germany, Austria and Switzerland decided to address this issue by developing new minimal standards for reporting the outcomes of AMEI clinical trials. The consensus presented here aims to provide a recommendation to enable better inter-study comparability.

Impact of COVID-19 on the work of Spanish dentists: An early response to the pandemic

2021

Background This study aimed to assess the quality of the information about COVID-19 that Spanish dentists felt they were provided; their opinion about the actions by Health Institutions; their perception of the risk infection at work; and the security measures implemented to prevent contagion. Material and Methods A specific questionnaire was developed and made available online from March 18th to 20th 2020. Dentists working in Spain were invited to answer. Questions were divided in 4 sections: demographic data and professional activity; specific information on COVID-19 and opinion about the decisions taken by Dental Councils and Health Authorities; risk assessment for SARS-CoV-2 in dental p…

Red Ear Syndrome

2016

The Red Ear syndrome (RES) is an intriguing syndrome originally described for the first time nearly 20 years ago. RES is characterized by unilateral/bilateral episodes of pain and burning sensation of the ear, associated with ipsilateral erythema. RES episodes are indeed isolated in some patients, but they can occur in association with primary headaches, including in particular migraine in the developmental age. Although the underlying pathophysiological mechanisms are still uncertain, in the recent years the described comorbidities have aroused increasing interest because of possible clinical implications. Moreover, RES seems to be more often associated with clinical features of migraine p…
