Delayed chronic intracranial subdural hematoma complicating resection of a tanycytic thoracic ependymoma
2015
Background To demonstrate that the diagnosis of an intracranial subdural hematoma should be considered for patients presenting with acute or delayed symptoms of intracranial pathology following resection of a spinal tumor. Case description We present a case of a 57-year-old woman found to have a chronic subdural hematoma 1 month following resection of a thoracic extramedullary ependymoma. Evacuation of the hematoma through a burr hole relieved the presenting symptoms and signs. Resolution of the hematoma was confirmed with a computed tomography (CT) scan. Conclusion Headache and other symptoms not referable to spinal pathology should be regarded as a warning sign of an intracranial subdural…
Radiation leakage study for the Valencia applicators
2011
Abstract Introduction and purpose The Valencia applicators which are accessories of the microSelectron-HDR afterloader (Nucletron, Veenendaal, The Netherlands) are designed to treat skin lesions. These cup-shaped applicators are an alternative to superficial/orthovoltage x-ray treatment units. They limit the irradiation to the required area using tungsten-alloy shielding, and are equipped with a tungsten-alloy flattering filter allowing the treatment of skin tumors, the oral cavity, vaginal cuff, etc. The tungsten-alloy thickness to shield radiation is not the same in all parts of the applicators. This fact led us to question whether the leakage radiation differs depending on where it is me…
Faut-il réaliser un scanner quand la protéine C réactive est élevée après chirurgie colorectale ? Résultats de la cohorte IMACORS
2017
Resume Introduction Les concentrations seriques de proteine C reactive (CRP) en deca d’un seuil predefini entre le 3e et le 5e jour postoperatoire sont un marqueur fiable de l’absence de complication infectieuse apres chirurgie colorectale. Cependant, la strategie a mettre en place en cas de CRP elevee n’est pas codifiee. Le but de ce travail etait d’analyser l’utilite du scanner dans cette situation au sein d’une cohorte prospective de chirurgie colorectale reglee. Methodes Entre novembre 2011 et avril 2015, les patients ayant une CRP > 125 mg/L au 4e jour postoperatoire d’une resection colorectale reglee dans l’un des 2 centres participants ont ete inclus prospectivement dans une base. To…
Prognostic value of PCR, IL-6 and IL-10 serum levels in determining postoperative complications after geriatric surgery in diabetic patients
2010
Background The onset of postoperative septic complications has been associated to serum levels of interleukin (IL) IL-6 and IL-10. [1,2]. We have extrapolated a diabetic group from a previous study to evaluate pre and postoperative profiles of some inflammatory markers (IL-6 , IL-10 and CRP). We related the data obtained to the onset of postoperative complications. Diabetic patients have been selected because of their high rate of post-operative complications, especially surgical wound infection.
The Role of Immunosenescence in Cerebral Small Vessel Disease: A Review.
2022
Cerebral small vessel disease (CSVD) is one of the most important causes of vascular dementia. Immunosenescence and inflammatory response, with the involvement of the cerebrovascular system, constitute the basis of this disease. Immunosenescence identifies a condition of deterioration of the immune organs and consequent dysregulation of the immune response caused by cellular senescence, which exposes older adults to a greater vulnerability. A low-grade chronic inflammation status also accompanies it without overt infections, an “inflammaging” condition. The correlation between immunosenescence and inflammaging is fundamental in understanding the pathogenesis of age-related CSVD (ArCSVD). Th…
A new implant-abutment connection for bacterial microleakage prevention: An in vitro study
2017
Purpose The aim of our study is to evaluate the ability of a new type of implant (Konus Implant System®, Industrie biomediche e farmaceutiche, Italy) to isolate the internal of an implant-abutment connection from the external environment. Materials and methods To identify the capability of the implant to protect the internal space from the external environment, the passage of genetically modified Escherichia coli across implant-abutment interface was evaluated. Implants were immerged in a bacterial culture for twenty-four hours and then bacteria amount was measured inside implant-abutment interface with Real-time PCR. Results Bacteria were detected inside all studied implants, with a median…
Assisted software design of a wide variety of windings in rotating electrical machinery
2014
In this paper a software developed by the Authors for winding design is presented. In particular, this software can be used as a valid aid in design and analysis for a wide variety of windings with generic number of phases, pole pairs, slot number, etc.. The calculation of winding factors and the evaluation of their harmonic distribution is also accomplished. The software is implemented in MATLAB® environment. By means of some examples, covering the most relevant winding types, the capabilities of this software will be shown. Particularly, integer and fractional slot, single and double layer winding, concentrated windings, imbrication, belt widening and belt shifting techniques can be treat…
Risk factors for bile leakage after liver resection for neoplastic disease.
2022
Biliary leakage (BL) remains the most frequent and feared complication after hepatoresective surgery. Placement of the abdominal drainage at the end of liver surgery remains controversial due to the delicate balance between risks and potential benefits in case of BL. The study was aimed to detect possible risk factors for BL occurrence after liver surgery. We enrolled all oncologic patients who underwent liver resection from June 2016 to March 2021. BL was diagnosed according to the ISGLS definition. We have examined demographic characteristics of the patients, type of neoplasia, presence of cirrhosis, neoadjuvant chemotherapy and type of intervention. Uni- and multivariable analyses were p…
Leakage Detection via Edge Processing in LoRaWAN-based Smart Water Distribution Networks
2022
The optimization and digitalization of Water Distribution Networks (WDNs) are becoming key objectives in our modern society. Indeed, WDNs are typically old, worn and obsolete. These inadequate conditions of the infrastructures lead to significant water loss due to leakages inside pipes, junctions and nodes. It has been measured that in Europe the average value of lost water is about 26 %. Leakage control in current WDNs is typically passive, repairing leaks only when they are visible. Emerging Low Power Wide Area Network (LPWAN) technologies, and especially IoT ones, can help monitor water consumption and automatically detect leakages. In this context, LoRaWAN can be the right way to deploy…
Microbiological assessment of the implant-abutment interface in different connections: cross-sectional study after 5 years of functional loading.
2014
Objective To evaluate the bacterial microflora present inside the implant connection and in the peri-implant sulcus fluid of healthy implants, and to analyze the relationships between these harboring sites for four different implant systems after at least 5 years of functional loading. Materials and methods A cross-sectional study was performed involving 40 patients treated with metal-ceramic cemented bridges supported by at least two healthy implants functionally loaded for 5 years. Four different implant-abutment connections were studied: external hexagon (control group), double internal hexagon (test group 1), internal hexagon with external collar (test group 2), and conical connection (…
