Use of bone scintigraphy in the early diagnosis of bisphosphonate related osteonecrosis of the jaw. Case report and review of the literature
2018
The main aim of the present report is to show the potential utility of bone scintigraphy for the diagnosis of jaw osteonecrosis. We report the history of a 62-year-old woman underwent breast cancer surgery in 2010. Moreover, patient received postoperative radiotherapy and chemotherapy. Intravenous bisphosphonates were also added to the treatment strategy to reduce the risk of bone metastasis. However, a hypermetabolic focus on left hemimandible was evidenced with a bone scintigraphy during follow up. After a careful study, the diagnosis of Bisphosphonate Related Ostneonecrosis of the Jaw (BRONJ) was carried out. This case highlights that bone scintigraphy may be extremely helpful for the ea…
Laser speckle imaging for early detection of microbial colony forming units
2021
In this study, an optical contactless laser speckle imaging technique for the early identification of bacterial colony-forming units was tested. The aim of this work is to compare the laser speckle imaging method for the early assessment of microbial activity with standard visual inspection under white light illumination. In presented research, the growth of Vibrio natriegens bacterial colonies on the solid medium was observed and analyzed. Both – visual examination under white light illumination and laser speckle correlation analysis were performed. Based on various experiments and comparisons with the theoretical Gompertz model, colony radius growth curves were obtained. It was shown that…
Motivos de participación en el Programa de Prevención del Cáncer Colorrectal de la Comunidad Valenciana según sexo, edad y clase social
2014
Objective: To know the reasons to participate or not in a colorectal cancer (CCR) screening programme and to analyze the differences by sex, age and social class. Methods: Cross-sectional study by a telephone survey directed to a sample of men and women aged between 50-74 year old, participants (n = 383) and non participants (n = 383) in the CCR screening programme of Valencian Community. Descriptive analysis and logistic regression models estimating the Odds Ratio (p < 0.05). Results: The main reasons to participate are "it is important for health" (97.9 %) and "the test is easy" (97.6 %); and to non participate are "no CCR symptoms" (49.7 %) and "didn't receive invitation letter" (48.3 %)…
Participación informada en el Programa de Prevención del Cáncer Colorrectal de la Comunidad Valenciana desde una perspectiva de género
2018
Abstract Objective: To examine the factors that influence informed participation in a Colorectal Cancer Screening Programme (CRCSP) from a gender perspective. Methods: Cross-sectional telephone survey directed to men and women invited to participate (2009-2010) in the Valencian Community CRCSP (Spain). Sample size: 785 subjects. Outcome variables: participation in CRCSP and being informed. Bivariate and multivariate analysis using logistic regression models (95% confidence interval [95%CI], p <0.05). Results: Being a woman (odds ratio [OR]: 1.52; 95%CI: 1.06-2.19), receiving information from a general practitioner (OR: 1.64; 95%CI: 1.05-2.55) and being informed (OR: 1.54; 95%CI: 1.08-2.21) …
Pap Testing in a High-Income Country with Suboptimal Compliance Levels: A Survey on Acceptance Factors among Sicilian Women
2018
Cervical cancer screening is uncommon, especially in low-income countries and among lower socioeconomic status people in high-income countries. The aims of this study were to examine the adherence of Sicilian women to Pap testing and to identify the determinants of this in a population with a secondary prevention attitude lower than high-income countries and the national average. A cross-sectional study called &ldquo
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 …
In vivo study of different methods for diagnosing pit and fissure caries
2015
Background In recent years the early detection of such caries has gained importance, since it may avoid unnecessary dental tissue damage and allow minimally invasive dental treatment. A study is made of 5 systems for diagnosing caries: traditional visual and tactile methods, DIAGNOdent, VistaProof and CarieScan. Material and Methods A prospective study was made in the Department of Stomatology, Dental Pathology and Therapeutics Teaching unit of the University of Valencia (Valencia, Spain), involving the analysis of 32 teeth (molars or premolars of both arches scheduled for filling or for use as posts in dental bridges) in 28 patients. The following caries diagnostic methods were applied: vi…
Recent advances on nanomaterial based electrochemical and optical aptasensors for detection of cancer biomarkers
2018
Abstract Cancer is a real menace to all societies globally since it is the leading cause of premature mortality in men and women. The incidence of malignancies is enhancing as a result of plenty factors. Physically and economically concerns that occur in cancers patients cannot be neglected. However, current diagnostic methods and cure duration do not fulfill patients requirements. Therefore, it is essential to detect and diagnose cancer biomarkers as soon as possible and overcome the current burdens. Novel aptasensors is emerging as one of the most promising strategies for early recognition of cancer. Aptamers an artificial DNA or RNA sequences, possess plenty of merits such as easy produc…
Early detection of contamination and defect in foodstuffs by electronic nose: A review
2017
Abstract Electronic nose (e-nose) has emerged as a potential instrument in various areas of food safety assessment for rapid early detection of contamination and defect in food production chain. E-nose is an innovative measurement system designed for detecting and discriminating complex odors through mimicking the working mechanism and the principal building blocks of the mammalian olfactory system. This paper describes a literature update of the applications of the e-nose for ensuring health and safety in the food industry. Finally, its future trend, perspectives and challenging problem are also mentioned.
The use of spiral CT in the detection and management of a permanent maxillary first molar with single root and single canal : a rare occurrence
2017
A sound knowledge of the normal tooth morphology and its numerous variations is essential to the success of endodontic therapy. While extra canals and lateral canals are routinely encountered and documented, there also exists the rare possibility of a fewer number of canals than normal. Early detection of such an occurrence is critical to the prevention of iatrogenic errors during endodontic treatment. The advent of spiral CT as a diagnostic tool serves as a much needed confirmation to understand the complex three dimensional anatomy of teeth. The aim of this case report is to highlight one such case reporting unusual morphology of the permanent maxillary first molar displaying single canal…
