Isolated non-compaction of the myocardium as a cause of coronary and cerebral embolic events in the same patient.

2009

A 44-year-old woman with a history of smoking and previous cerebral thrombo-embolism presented to the emergency department with prolonged chest pain and ECG changes showing an acute anterior myocardial infarction. She was referred to the cath-lab for primary angioplasty. Coronary angiography showed a thrombotic occlusion at the origin of first diagonal …

High-Frequency Rotational Angioplasty

1991

In 19 patients with significant coronary artery disease, PTCR was used instead of PTCA. The PTCR was successful in all patients, but in nine patients additional PTCA was successfully performed. Coronary luminal narrowing could be reduced from 78 ± 19% to 32 ± 14% after rotablation and by combined treatment to 21 ± 14%. Only in one patient did coronary dissection occur; the patient was sent to surgery and had an uneventful outcome. No vessel perforation was observed. In one patient peripheral diagonal branch occlusion occurred. All vessels were open according to 24-control coronary angiography. Restenosis (>70% stenosis) occurred in 4/15 patients controlled after 6 months, mainly in those wi…

Optical multichannel sensing of skin blood pulsations

2004

Time resolved detection and analysis of the skin back-scattered optical signals (reflection photoplethysmography or PPG) provide information on skin blood volume pulsations and can serve for cardiovascular assessment. The multi-channel PPG concept has been developed and clinically verified in this study. Portable two- and four-channel PPG monitoring devices have been designed for real-time data acquisition and processing. The multi-channel devices were successfully applied for cardiovascular fitness tests and for early detection of arterial occlusions in extremities. The optically measured heartbeat pulse wave propagation made possible to estimate relative arterial resistances for numerous …

Condylar position indicator and T-scan system II in clinical evaluation of temporomandibular intracapsular disease.

2012

The pathogenesis of temporomandibular joint intracapsular disease (TMJI) is multifactorial and its diagnosis is not easy. In this work authors show two types of clinical analysis: the Condylar Position Indicator (CPI) and T-Scan 2 system.Twenty patients (mean age of 24.5 years) with TMJI problem and 10 healthy matched subjects (mean age: 25.4 years) were selected. Analysis of TMJI was performed on each patient by means of Condylar Position Indicator (CPI) and T-Scan System II tests.Eight patients presented vertical symmetrical condylar distraction greater than healthy subjects (P-value0.001). T-Scan showed a difference of Percentage of Force (POF) not greater than 5%. Seven patients showed …

Survival rates of a lithium disilicate-based core ceramic for three-unit esthetic fixed partial dentures: a 10-year prospective study.

2013

Purpose The aim of this prospective study was to evaluate the clinical efficacy and long-term survival rate of three-unit fixed partial dentures (FPDs) made from lithium disilicate-based core ceramic. Materials and methods Twenty-one three-unit FPDs were placed in 19 patients to replace single lost teeth in the esthetic area, following a study protocol that took clinical, esthetic, and radiologic aspects into consideration. Each case was reviewed at 1 week following placement, at 6 months, and then annually for 10 years. Statistical analysis was performed using Kaplan-Meier survival analysis. Results Out of the 19 patients, 14.3% presented reversible postoperative sensitivity. Recession was…

Arch width changes in patients with Class II division 1 malocclusion treated with maxillary first premolar extraction and non-extraction method

2016

Background The aim of this study was to determine arch width changes during maxillary first premolars extraction and non-extraction treatment in patients with Class II division 1 malocclusion. Material and methods Dental casts of 91 Class II division 1 patients (36 males and 55 females) were evaluated. The minimum age of the subjects at the beginning of treatment was above 16 years. 48 patients were treated with extraction of the maxillary first premolars and 43 patients were treated without extraction. Pre- and post-treatment maxillary and mandibular inter-canine and inter-molar arch widths were measured. Results At the end of treatment, maxillary and mandibular inter-canine widths of both…

Budd-Chiari Syndrome: Spectrum of Imaging Findings

2007

OBJECTIVE: The objective of our study was to illustrate the imaging findings of Budd-Chiari syndrome, including CT, MRI, sonographic, and angiographic findings. CONCLUSION: The key imaging findings in Budd-Chiari syndrome are occlusion of the hepatic veins, inferior vena cava, or both; caudate lobe enlargement; inhomogeneous liver enhancement; and the presence of intrahepatic collateral vessels and hypervascular nodules. Awareness of these findings is important for early diagnosis and appropriate treatment.

Oral health in children with physical (Cerebral Palsy) and intellectual (Down Syndrome) disabilities: Systematic review I

2016

Introduction Traditionally, patients with physical and/or intellectual disabilities presented greater oral pathology, owing to their condition and to other external factors. Improved social and health conditions make it necessary to update knowledge on their oral and dental health. Material and Methods For this purpose, a bibliographic review was done regarding the state of oral health of children with these two types of disability, in comparison with a control group. Some of the guidelines of the PRISMA statement were taken into account. The ranking of the articles found is based on the modified Newcastle-Ottawa Quality Assessment Scale. The final number of articles evaluated was 14. Param…
