Comparison of results of combined liver-kidney transplantation vs. isolated liver transplantation
2013
Introduction. Combined liver-kidney transplantation (LKT) is the best therapeutic option for patients with end-stage liver and kidney disease. Objectives. To analyze baseline characteristics and clinical outcome of LKT compared to isolated liver transplantation (LT). Material and methods. The study included 16 LKT performed between 1998 and 2006 and 32 LT matched by age, sex, date and indication for transplantation. Demographic, pretransplant, post-transplant and survival variables were analyzed. Results. As planned by the study design, mean age, distribution by sex and indication for LT were similar between groups. The most common indication for LT was HCV- and/or alcohol-induced cirrhosis…
The Role of Endoscopy in the Treatment of Acute Traumatic Anterior Epidural Hematoma of the Cervical Spine: Case Report
1997
OBJECTIVE AND IMPORTANCE: Epidural hematoma (EDH) of the spine represents an uncommon neurosurgical disorder that sometimes requ;res emergent surgical decompressive therapy. Traumatic EDH of the cervical spine is exceedingly rare. The hematoma is usually located dorsally in the epidural space. We present one case of acute EDH located ventrally in the cervical spine. Special emphasis is placed on the role of spinal endoscopy in surgical treatment. CLINICAL PRESENTATION: After a fall from a tree, a 69-year-old man with rapidly increasing tetraparesis was referred to our institution. Plain films of the cervical spine revealed nothing abnormal. The results of computed tomography were highly sus…
Computer-aided detection of cerebral microbleeds in susceptibility-weighted imaging.
2014
Susceptibility-weighted imaging (SWI) is recognized as the preferred MRI technique for visualizing cerebral vasculature and related pathologies such as cerebral microbleeds (CMBs). Manual identification of CMBs is time-consuming, has limited reliability and reproducibility, and is prone to misinterpretation. In this paper, a novel computer-aided microbleed detection technique based on machine learning is presented: First, spherical-like objects (potential CMB candidates) with their corresponding bounding boxes were detected using a novel multi-scale Laplacian of Gaussian technique. A set of robust 3-dimensional Radon- and Hessian-based shape descriptors within each bounding box were then ex…
Antimicrobial Lubricant Did Not Reduce Infection Rate in Transrectal Biopsy Patients in a Large Randomized Trial Due to Low Complication Rates
2018
Abstract Background Transrectal prostate biopsy (pbx) is the most frequent outpatient procedure in the urological field. Septic complications are a major health issue. Objective To evaluate complication rates with or without an antimicrobial lubricant. Design, setting, and participants A total of 1000 patients received pbx between 2013 and 2015. Information about complications was collected by a 3-wk questionnaire. Return rate was 73.2% (n = 732). Intervention Randomization for pbx with the instillation of an antimicrobial lubricant (intervention group, n = 385) or the standard lubricant (control group, n = 347) was performed. Outcome measurements and statistical analysis Multivariable anal…
<title>Noninvasive detection of intracerebral hemorrhage using near-infrared spectroscopy (NIRS)</title>
1998
Intracerebral Hemorrhage (IH) is an important cause of secondary brain injury in neurosurgical patients. Early identification and treatment improve neurologic outcome. We have tested Near Infrared Spectroscopy (NIRS) as an alternative noninvasive diagnostic tool compared to CT-Scans to detect IH. We prospectively studied 212 patients with neurologic symptoms associated with intracranial pathology before performing a CT-scan. NIRS signals indicated pathologies in 181 cases (sensitivity 0.96; specificity 0.29). In a subgroup of subdural hematomas NIRS detected 45 of 46 hematomas (sensitivity 0.96; specificity 0.79). Identification of intracerebral hemorrhage using NIRS has the potential to al…
Transient Focal Neurological Events in Cerebral Amyloid Angiopathy and the Long-term Risk of Intracerebral Hemorrhage and Death: A Systematic Review …
2021
Importance Transient focal neurological episodes (TFNEs) are a frequently overlooked presentation of cerebral amyloid angiopathy (CAA), a condition with prognostic implications that are still not well described. Objective To perform a systematic review and meta-analysis to examine the factors associated with incident lobar intracerebral hemorrhage (ICH) and death in patients with CAA presenting with TFNEs. Data Sources A systematic review and individual participant meta-analysis including (1) a hospital-based cohort and (2) the results obtained from a systematic search performed in MEDLINE and Embase completed in December 2019. Study Selection Included studies were observational reports of …
Experimental Hypertensive Intracerebral Mass Hemorrhage in Cats
1986
About two–thirds of all patients with spontaneous intracerebral hemorrhage suffer from systemic hypertension. Additionally systemic hypertension is the main factor indicating a poor prognosis of intracerebral hemorrhage. This has been shown in our statistical evaluation of 117 cases of conservatively treated spontaneous intracerebral hemorrhage. More than 48% of the hypertensive patients died, but only 30% of the normotensive patients (Fig. 1). In an experimental study we investigated the influence of systemic hypertension and normotension on epidural pressure and on the formation of brain edema during the first 12 h after artificial intracerebral hemorrhage.
The Influence of Systemic Hypertension on Intracranial Pressure and Edema Formation in Experimental Intracerebral Hemorrhage
1986
Systemic hypertension is not only the most frequent cause of intracerebral hemorrhage but also the most important complication of this disease. In our clinical investigation of 117 cases almost 70% of the patients suffered from systemic hypertension. Despite advances in diagnosis (Schiirmann, Dei Anang, 1980) mortality of hypertensive patients was 48%. Normotensive hemorrhages showed a better prognosis: only 31% of the patients died and 33% (17% in hypertensive patients) obtained good neurological recovery (Wallenfang et al., 1985).
Les accidents vasculaires cérébraux du nouveau-né et de l’enfant
2009
The clinical presentation, risk factors, causes, vital or functional prognosis, and acute management options for stroke occurring in neonates and children are specific, differing from those observed in young adults. Compared with the adult population, less is known about the epidemiology of stroke in the under-18 population where the disease could become more frequent because of advances in both neonatal resuscitation techniques for cerebral disorders and neuroimaging techniques enabling the diagnosis of small lesions. Clinical features are often delayed, especially in neonates, and unlike epilepsy or dystonia of the affected limb, which are frequent complications, aphasia is rather rare. T…
Postlumbar Puncture Headache Syndrome
2003
Publisher Summary This chapter presents a study on acute and chronic pain related to postlumbar puncture headache syndrome. The symptoms of the postlumbar puncture headache (PLPH) syndrome are positional, beginning in the upright posture and subsiding or improving when the patient reclines. Sometimes symptoms of PLPH occur spontaneously without a detectable dural defect. In these instances, suggested causes include a hyperactive resorption of cerebrospinal fluid (CSF) or a spontaneous mechanical dural hole. Magnetic resonance imaging (MRI) scans in patients with intracranial hypotension—either after LP or spontaneously—show meningeal enhancement, subdural effusions, and downward brain displ…
