Minimally invasive techniques in the treatment of saphenous varicose veins.
2008
Lower extremity venous insufficiency is common and increases with age. In addition to classical symptoms, it may result in skin changes and venous ulcers. Chronic venous insufficiency has a great impact on patients' health-related quality of life and is associated with considerable health care costs. Surgical ligation Of the junction with or without stripping has been the standard of care in the treatment of insufficient great and small saphenous veins. However, the recurrence rates are relatively high and surgery may be associated with serious adverse events and considerable down time; it is also cosmetically Suboptimal. To improve efficacy, patients' health-related quality of life and tre…
Mirizzi syndrome in a patient with partial gastrectomy with Billroth II anastomosis: A case report
2020
Highlights • Obstructive jaundice may be a challenge for differential diagnosis. • Mirizzi Syndrome may simulate clinical and radiological presentation of common bile duct stones. • ERCP hardly achieves cannulation of biliary duct in altered anatomy, so gastroscope may be a correct choice in these cases. • Surgical treatment is essential in Mirizzi Syndrome.
Intravenous thrombolysis for acute ischaemic stroke in patients on direct oral anticoagulants.
2018
BACKGROUND AND PURPOSE Whereas intravenous thrombolysis (IVT) is allowed for acute ischaemic stroke in patients on vitamin K antagonists with international normalized ratio ≤1.7, there are no similar recommendations for patients on direct oral anticoagulants (DOACs), notably due to the lack of coagulation tests to assess the therapeutic effects. Although the literature is scarce, consisting of small case series and retrospective studies, considering the frequency of this situation the French Vascular Neurology Society and the French Study Group on Haemostasis and Thrombosis have worked on a joint position paper to provide a practical position regarding the emergency management of ischaemic …
The role of electrotherapy in reducing the pain of patients with knee osteoarthritis during the COVID-19 pandemic
2020
Introduction. Osteoarthritis is considered to be the most common form of arthritis and a leading disability cause worldwide, especially due to the painful symptom. The latter is a clinical marker in evaluating the limits of joint mobility and therefore, the pain reduction is a goal of the recovery treatment for patients with knee osteoarthritis. The purpose of this study was to show whether the pain phenomenon characteristic of knee osteoarthritis can be reduced by electrotherapy, even in the context of the COVID-19 pandemic. Material and method. The study lasted 5 months and included 171 patients diagnosed clinically and radiologically with knee osteoarthritis. The followed parameters were…
Effects of sclerosing agents on head and neck hemangiomas : a systematic review
2019
Background The aim of this study was to systematically review the literature for studies that investigated the effects of sclerosing agents on head and neck hemangiomas. Material and methods Clinical trials, cohort studies, and descriptive studies were considered eligible and selected in a two-phase process. Six main electronic databases, in addition to three grey literature databases, were searched. Risk of bias (RoB) was assessed using the "Meta-Analysis of Statistics Assessment and Review Instrument" checklist. From fifty-six considered eligible, five were finally included. Results One article were judged at low, one at moderate, and three at high RoB. The sclerosing agents investigated …
Outpatient Treatment of Hemorrhoidal Disease: The Alternative Way to Treat Hemorrhoidal Disease in a Simple, Safe and Effective Manner.
2021
Background:: Hemorrhoidal disease is a widespread problem in healthy working patients. The traditional surgical approaches cause a loss of several working days related to the post-- operative course that is often painful. To avoid these problems while offering a symptoms resolution in patients with low degrees hemorrhoids, the non-surgical treatments are nowadays largely proposed in proctological clinics. Methods: We resume the recent literature on the issue to offer a practical and easy to use guide for clinicians. Results: Rubber band ligation, injection sclerotherapy and infrared coagulation are cost effective, safe and effective treatments for patients with II- and III-degree hemorrhoi…
Clinical Pitfalls in Diagnosis of Nonmuscle-Invasive Bladder Cancer
2015
Current global economic crisis imposes healthcare system to reduce unnecessary investigations and increase early detection of tumors, to decrease the costs of an advanced disease. Several diagnostic pitfalls may occur dealing with bladder cancer (BC), particularly in nonmuscle-invasive (NMIBC) one. Hematuria, the commonest sign in NMIBC, is often underestimated. Urinary cytology is highly specific for high-grade tumors, but has a low sensitivity for low-grade BC, is operator dependent, and not always obtainable in clinical practice. Numerous urinary tests are available to ameliorate the accuracy of cytology, but none of them is routinly used in urological practice. Ultrasound could hardly …
High-performance liquid chromatographic determination of diuretics in urine by micellar liquid chromatography.
1992
The use of micellar liquid chromatography for the determination of diuretics in urine by direct injection of the sample into the chromatographic system is discussed. The retention of the urine matrix at the beginning of the chromatograms was observed for different sodium dodecyl sulphate (SDS) mobile phases. The eluent strengths of a hybrid SDS-methanol micellar mobile phase for several diuretics were compared and related to the stationary phase/water partition coefficient with a purely micellar mobile phase. The urine band was appreciably narrower with a mobile phase of 0.05 M SDS-5% methanol (v/v) at 50 degrees C (pH 6.9). With this mobile phase the determination of bendroflumethiazide an…
First combined flux chamber survey of mercury and CO2 emissions from soil diffuse degassing at Solfatara of Pozzuoli crater, Campi Flegrei (Italy): M…
2014
Abstract There have been limited studies to date targeting gaseous elemental mercury (GEM) flux from soil emission in enriched volcanic substrates and its relation with CO 2 release and tectonic structures. In order to evaluate and understand the processes of soil–air exchanges involved at Solfatara of Pozzuoli volcano, the most active zone of Campi Flegrei caldera (Italy), an intensive field measurement survey has been achieved in September 2013 by using high-time resolution techniques. Soil–air exchange fluxes of GEM and CO 2 have been measured simultaneously at 116 points, widely distributed within the crater. Quantification of gas flux has been assessed by using field accumulation chamb…
Investigation on the stability of dispersion of zirconia nanoparticles prepared by microwave- hydrothermal synthesis
2005
Difficulties in reproducing the performances of nanoparticles dispersions are obstructive for the progress of the nanotechnology. A plausible reason for this variability is the lack of the control of the stability as well as the dimensions of the nanoparticles in the dispersions. In this work we report results of investigations on the stability of zirconia nanoparticles in aqueous medium, monitoring nanoparticles sizes by means of Transmission Electron Microscopy (TEM), Dynamic Light Scattering (DLS). Nanocrystalline zirconia powders, prepared by microwave-hydrothermal synthesis, were determined to be 6-8 nm in size by TEM observations. By using DLS technique the as-prepared dispersions wit…
