Non-endodontic periapical lesions clinically diagnosed as endodontic periapical lesions: A retrospective study over 15 years
2021
Background This study aimed to provide the frequency and demographic data of non-endodontic periapical lesions clinically misdiagnosed as endodontic periapical lesions from a Southeast Asian population over a 15-year period. Material and methods A retrospective study was conducted from departmental archives between 2005 and 2019. Cases clinically diagnosed as endodontic periapical lesions were retrieved. Then, cases with a histopathological diagnosis of non-endodontic periapical lesion were selected. Demographic data of non-endodontic periapical lesions were recorded. Radiographic features of cases with available radiographs were analyzed. Results Of 1,566 cases clinically diagnosed as endo…
Delirium: From the Operating Room to the ICU
2020
Delirium is a transitory and reversible syndrome which is potentially avoidable; nevertheless represents the most common acute encephalic dysfunction in critically ill patients. Despite this population being daily treated by anesthesiologists in the operating rooms and by critical care physicians in the Intensive care unit, delirium remains an underdiagnosed condition that is associated with a significative increase in morbidity and mortality. Furthermore, it is associated with higher costs and length of stay.
Health Policy Model: Long-Term Predictive Results Associated with the Management of HCV-Induced Diseases in Italy
2014
Background: This study is aimed at describing the epidemiological and economic burden that HCV will generate in the next few years in Italy. Furthermore, the impact that future anti-HCV treatments may have on the burden of disease was considered. The analysis has been developed over the period 2013-2030 from the Italian National Health Service (NHS) perspective.Methods: A published system dynamic model was adapted for Italy in order to quantify the HCV-infected population, the disease progression and the associated cost from 1950 to 2030. The model structure was based on transition probabilities reflecting the natural history of the disease. In order to estimate the efficacy of current anti…
ACTIVATION (PercutAneous Coronary inTervention prIor to transcatheter aortic VAlve implantaTION)
2021
Abstract Objectives This study sought to determine if percutaneous coronary intervention (PCI) prior to transcatheter aortic valve replacement (TAVR) in patients with significant coronary artery disease would produce noninferior clinical results when compared with no PCI (control arm). Background PCI in patients undergoing TAVR is not without risk, and there are no randomized data to inform clinical practice. Methods Patients with severe symptomatic aortic stenosis and significant coronary artery disease with Canadian Cardiovascular Society class ≤2 angina were randomly assigned to receive PCI or no PCI prior to TAVR. The primary endpoint was a composite of all-cause death or rehospitalizat…
Postoperative Lens Position Preoperatively Determined by Scheimpflug Photography
1999
The position of the artificial lens has an important influence on refractive power calculation. We compared the position of the crystalline lens with that of the artificial lens after cataract surgery by means of Scheimpflug photography. A difference in position of approximately 0.8 mm in the anterior direction could be determined.
Endoscope-assisted Craniotomy
1995
We describe a surgical technique to improve visualization of deep brain structures during craniotomy. The technique, developed in a cadaveric model, combines the use of an operating microscope and a solid-rod lens endoscope. Addition of the endoscope during craniotomy allows the operator to visualize structures that otherwise might not have been seen. An approach to the brain stem is demonstrated.
Übereinstimmung von klinischer Beurteilung, Heidelberg-Retina-Tomograph (HRT) und Nerve Fiber Analyzer (GDx) in der Glaukomdiagnostik
2004
BACKGROUND We have made a comparison of clinical evaluation, Heidelberg-Retina-Tomograph (HRT) and Nerve Fiber Analyzer (GDx) in diagnosing glaucoma. MATERIALS AND METHODS One eye of 38 glaucoma patients and 26 non-glaucoma patients was examined with HRT and GDx. Assignment of the patients into the two groups by clinical evaluation was performed on the basis of visual field and optic disc results. As classification criterion for glaucoma/non-glaucoma by means of the instruments we employed the statistical classification of the HRT and "the number" of the GDx. Statistical analysis was performed with Cohen's kappa and McNemar tests. Additionally, ROC curves for evaluation of the sensitivity a…
Use of digital displays and ocular surface alterations: A review.
2020
Digital display use has been accepted to be implicated as a contributing factor for dry eye disease (DED). Abnormal blinking during computer operation, including a reduced blink rate and an incomplete eyelid closure, increased palpebral fissure as consequence of high visualization angles, and meibomian gland dysfunction associated to long-term display use, are behind the increased prevalence of dry eye signs and symptoms found in digital display users. Previous research reveals significant reductions in tear volume and stability, alterations in tear film composition, including increased osmolarity, inflammatory cytokines, oxidative stress markers and reduced mucin secretion, eyelid abnormal…
Preoperative Botulinum Toxin and Progressive Pneumoperitoneum in Loss of Domain Hernias-Our First 100 Cases
2020
Objectives: Preoperative botulinum toxin type A (BT) and progressive pneumoperitoneum (PPP) are useful tools in the preparation of patients with loss of domain hernias (LODH). The purpose of our retrospective study is to report our experience in the treatment of 100 consecutive patients with LODH, with the combined use of these techniques. Methods: Of the 753 patients operated on for ventral incisional hernia between June 2010 and December 2018 in our hospital, 100 patients with LODH were analyzed retrospectively. Diameters of abdominal cavity and hernia sac, and volumes of incisional hernia (VIH) and abdominal cavity (VAC) were calculated from CT scan, based on the index of Tanaka. Results…
Spectral imaging as a tool for the evaluation of skin cancer post-operative scars
2020
Skin cancer is the most common type of cancer in the USA and worldwide.1 An early diagnosis is the key to a successful treatment. Among the skin cancers, the malignant melanoma (MM) accounts for 1% of the cases while it is responsible for the majority of deaths. Basal cell carcinoma (BCC) is the most common form of skin cancer with a very low mortality rate.2 Unfortunately, skin cancer recurrence is a common problem for MM and BCC patients. We propose a post-operative scar screening with non-invasive autofluorescence (AF) imaging to detect an early growth of any residual tissue from the cancer removal procedure. The screening images can serve also as a visual evidence for the post-op patien…
