Introduction: Non-invasive methods for imaging varicose veins allow quantification and evaluation of venous diseases. This paper will describe a technique to visualize superficial (subdermal) varicose veins using digital infrared imaging and analysis with special software. Method: After image acquisition, the pictures were analysed with special software that segmented the varicose veins and calculated the surface area (per gridblock) occupied by varicose veins. By comparing the surfaces occupied by varices before and after a specific treatment, one can establish which treatment method performs the best. Aim for the future: Validation of this technique and quantification of the effects of treatment modalities for superficial (subdermal) varicose veins. We also investigate the use of this technique for the other clinical CEAP stages and the potential resemblance with duplex scanning.

Selection Of

Functional assessment may be important in the selection of treatment for the post thrombotic limb. Phlebography demonstrates the anatomy of the veins and their valves but this information is often incomplete and does not necessarily reflect venous function. Pressure measurements correlate well with function, but this invasive technique is not practicable for routine use or repeated measurements.Foot volumetry is a simple non-invasive technique which measures volume at rest and gives a continuous record of changes during exercise (Thulesius et al 1973). However reports on the reproducibility of this technique and its use in the study of venous function are few. On the basis of history, clinical examination and in those with suspected deep venous insufficiency ascending phlebography, 63 patients were divided into 3 groups: normal superficial varicose veins and deep venous insufficiency. There was good reproducibility. Preliminary analysis indicates that deep venous insufficiency may be diagnosed on the basis of a reduced expelled volume on exercise and a more rapid refilling phase after exercise. We conclude that foot volumetry is a useful non-invasive technique in the assessment of deep venous insufficiency. Further studies concerning its application to selection of specific treatment for the post-thrombotic limb are indicated.Thulesius et al (1973)VASA 2 325-329

The significant growth in scientific and technological advancements within the field of dentistry has resulted in a wide range of novel treatment modalities for dentists to use. Photodynamic therapy (PDT) is an emerging, non-invasive treatment method, involving photosensitizers, light of a specific wavelength and the generation of singlet oxygen and reactive oxygen species (ROS) to eliminate unwanted eukaryotic cells (e.g., malignancies in the oral cavity) or pathogenic microorganisms. The aim of this review article is to summarize the history, general concepts, advantages and disadvantages of PDT and to provide examples for current indications of PDT in various subspecialties of dentistry (oral and maxillofacial surgery, oral medicine, endodontics, preventive dentistry, periodontology and implantology), in addition to presenting some images from our own experiences about the clinical success with PDT.

Introduction: Fibromyalgia syndrome is characterized by musculo-skeletal pain. Heart rate variability (HRV) is a versatile and promising non-invasive marker of the autonomous nervous system. Micro-physiotherapy involves manual physiotherapy that seeks to identify the primary cause of a disease or symptom and to stimulate self-healing, in which the body recognizes the aggressor (antigen) and begins the elimination process, through cellular and tissue reprogramming. Method: The sample was composed of 15 individuals, aged between 35 and 40 years, with fibromyalgia. The Nerve Express method was used to assess the variability of the heart rate. Two sessions of micro-physiotherapy were conducted using global methods, with an interval of 45 days between sessions. Results: Based on the HRV results, the high frequency band was confirmed at p=0.203, with the low frequency recording a statistically significant value of p=0.001, thereby demonstrating sympathetic activity. Upon comparison of the mean heartbeat before and after treatment, a value of p=0.0006 was obtained. A value of p=0.049 was recorded in the analysis of the median R-R interval values. Conclusion: The use of micro-physiotherapy as a treatment method for fibromyalgia effectively improved the lives of patients by promoting sympathicotonia.

Abstract Aqueous cleaning of works of art on paper is one of the most important and delicate steps in a conservation process. It allows the removal of inorganic (metals) and organic substances, such as degradation products and other contaminants. These substances are responsible for yellowing, weakening, and loss of mechanical properties of paper. In this article, the cleaning effect of gellan gum was assessed on xuan paper, a traditional Chinese paper different in composition and papermaking technology compared to many Western papers. To assess the effect of gellan gum on xuan paper, its characteristics were studied before and after cleaning utilizing non-invasive and micro-invasive techniques. Results were compared to those obtained when treating Western papers and indicated that gellan gum can be applied effectively for aqueous cleaning of xuan paper.

Electrical Bioimpedance ◽  
Low Amplitude

Thoracic electrical bioimpedance is a new non-invasive technique for obtaining haemodynamic parameters. The method involves the passing of low amperage, high frequency current through the thorax. The current induces a change of resistance within the thorax, which is registered by electrodes. The overall impedance of the thorax is a measure of the electrical resistance of the thorax to this high frequency, low amplitude current. In clinical practice, thoracic electrical bioimpedance has been applied in diagnostic, therapeutic, and prognostic use in patients with heart failure and hypertension, patients with pacemakers, within the scope of early diagnosis of implant rejection following heart transplantation, as well as in patients with kidney disorders, before and after dialysis. However, one of its most important applications is in the determination of antihypertensive therapy, because it provides the parameters that reflect the genesis of arterial blood pressure, in assessing these parameters, optimal therapy adjusted to the haemodynamic status of each patient can be prescribed.

Central sleep apnoea and Cheyne-Stokes respiration are common forms of sleep-disordered breathing, particularly in patients with co-morbidities such as cardiac and renal disease which, however, often do not require specific treatment. Physicians may encounter such patients in their outpatient clinics or as ward referrals in hospital. A typical case is presented to aid the approach to such patients, including how to make an accurate diagnosis, which of the various treatment modalities to use, and what to do if a treatment fails. The evidence for the different interventions is explored, including oxygen, modes of non-invasive positive airway pressure, and drug treatments, with particular attention to groundbreaking studies.

No data have been published on the use of infrared thermography (IRT) to evaluate sheep emotions. We assessed whether this technique can be used as a non-invasive measure of negative emotions. Two voluntary animal approach (VAA) tests were conducted (and filmed) on five ewes before and after being restrained. The restraining process was performed by a handler for five minutes. IRT was used during restraint and the VAA tests. The lacrimal caruncle temperature was significantly higher during restraint and in the VAA test after the restraint compared with the VAA test before the restraint (Wilcoxon’s test; p = 0.04). The latency period until first contact was longer in the second VAA test (132 s) than in the first one (60 s). Our preliminary results suggest that IRT, combined with behavioral data, is a non-invasive technique that can be useful to assess stress and infer about negative emotions in sheep.

Background: Post-thyroidectomy vocal cord palsy is a significant procedure associated complication and a notable contributor for medico-legal litigation. The standard technique for vocal cord evaluation and the most commonly used tool is direct laryngoscopy. Endocrine surgeons generally address the patients to otolaryngologist for laryngoscopy, leading to extra expense and time loss. Laryngoscopy causes patient annoyance and could potentially contribute to poor patient compliance. Ultrasonography is a non-invasive technique that is regularly used by endocrine surgeons to examine the thyroid region.Methods: A prospective study conducted on patients who underwent thyroidectomy between September 2016 and August 2017 at endocrine surgery department in a tertiary care institute (South India), Surgeon performed ultrasound (SPU) and Video laryngoscopy (VDL) was performed before and after elective thyroidectomy.Results: 155 patients who consented were categorized in the study, 2 of the patients included in the study had preoperative vocal cord palsy and 12 of them had unilateral postoperative vocal cord palsy detected using VDL. In general, the postoperative vocal cord palsy rate was 6.45%. Postoperative SPU was ineffective in assessing vocal cords in 16(10.32%) of patients. SPU had a sensitivity of 83.33% and negative predictive value of 97.90%, for the visualization of vocal cords in the postoperative period.Conclusions: SPU is convenient and non-invasive technique which could provide our speciality with cheap yet powerful diagnostic tool for vocal cord assessment in post-thyroidectomy patients and can potentially decrease the requirement of difficult and cumbersome VDL.

Objectives. Electrical impedance spectroscopy (EIS) is a harmless non-invasive technique that allows to measure and monitor different physiological parameters. One of the problems with establishing new procedures based on EIS is difficulty to distinguish between tissue types. For that reason, our research group have decided to assess a possibility to use nanomagnetite as a contrast medium in EIS procedures. In this work we present characterization the electrical properties of a porcine heart tissue by EIS using a magnetite particles suspension as contrast medium. Methodology. SP-150 from BioLogic Science Instruments was used as EIS equipment. Porcine heart tissue was used as biological tissue. Nanomagnetite particles were synthetized by coprecipitation and combustion methods and named NM1 and NM2, respectively. EIS device was connected at each ventricle through four hypodermic needles (38mm). Left and right ventricle was injected with NM1 and NM2 particles, respectively. Impedance measurements were acquired for each ventricle before and after the injection. Contribution. Both samples of magnetite nanoparticles were able to change electrical properties of heart tissue. Studies in vivo must be performed in order to confirm the conclusion.
