Nerve injury in fractures of the condylar neck.
1977
Summary Although fractures of the condylar neck belong to the most frequent injuries of the jaws, and various nerves are found in close proximity to the temporomandibular joints, only little mention is made in the literature of neurological complications arising from accidents. We have therefore carried out a prospective study on nerve injuries in 237 fractures of the articular process in the period 1971–1975. We found two cases of post-traumatic Frey's syndrome, whereby the syndrome developed from a post-traumatic auriculotemporal neuralgia. We also found loss of function of auriculotemporal, buccal and facial nerves, and loss of taste sensation of the tongue in another case, caused by dam…
Activity of superoxide dismutase copper/zinc type and prognosis in a cohort of patients with coronary artery disease.
2015
Aim: Superoxide dismutase (SOD) is important to control reactive oxygen species, but the relevance to human disease like coronary artery disease (CAD) and underlying ischemia/reperfusion injury is not clarified. Methods: For this study, 2239 patients with known CAD were prospectively followed with a median follow-up time period of 3.6 years and a maximum of 6.9 years. During follow-up cardiovascular death was reported in 103 cases. Results: SOD activity (log-transformed) was investigated as continuous and categorical variable, showing a significant influence on outcome in the fully adjusted model (p = 0.045). Conclusion: Increased SOD activity beyond the normal range in the human physiolog…
Incidence, risk factors, and prognosis of gastrointestinal hemorrhage complicating acute renal failure.
2001
Incidence, risk factors, and prognosis of gastrointestinal hemorrhage complicating acute renal failure. Background Few prospective data are currently available on acute gastrointestinal hemorrhage (AGIH) as a complication of acute renal failure (ARF). The aim of the present study was to define incidence, sources, risk factors, and outcome of AGIH in patients with ARF. Methods We performed a prospective study on an inception cohort of 514 patients admitted for ARF to a nephrology intermediate care unit. Data on clinical risk factors for bleeding, frequency of occurrence of AGIH, length of hospital stay, and in-hospital mortality were collected. Independent predictors of AGIH were identified.…
Safety of meglumine gadoterate (Gd-DOTA)-enhanced MRI compared to unenhanced MRI in patients with chronic kidney disease (RESCUE study).
2012
To prospectively compare the renal safety of meglumine gadoterate (Gd-DOTA)-enhanced magnetic resonance imaging (MRI) to a control group (unenhanced MRI) in high-risk patients.Patients with chronic kidney disease (CKD) scheduled for MRI procedures were screened. The primary endpoint was the percentage of patients with an elevation of serum creatinine levels, measured 72 ± 24 h after the MRI procedure, by at least 25 % or 44.2 μmol/l (0.5 mg/dl) from baseline. A non-inferiority margin of the between-group difference was set at -15 % for statistical analysis of the primary endpoint. Main secondary endpoints were the variation in serum creatinine and eGFR values between baseline and 72 ± 24 h …
Prevention of pressure injuries in critically ill children: A preliminary evaluation
2020
Abstract Aims To evaluate a prevention strategy implemented to reduce incidence and severity of positioning related pressure injuries affecting pediatric patients in a pediatric critical care unit. Secondary objective was to evaluate compliance with preventive recommendations. Background The skin in infants or children has important physiological and anatomical differences compared with adults. Further, factors such as the immaturity of the skin and limited activity and mobility in pediatric critical care unit, along with the pressure exerted by medical devices, increases the risk of pressure ulcers in infants and children. The most effective preventive measures specific to this intensive c…
Studies on the disposition, metabolism and hepatotoxicity of coumarin in the rat and Syrian hamster.
2002
The hepatotoxicity, metabolism and disposition of coumarin has been compared in male Sprague-Dawley rats and Syrian hamsters. The treatment of rats for 12, 24 and 42 weeks with diets containing 0.2 and 0.5% coumarin resulted in hepatotoxicity and increased relative liver weights. While levels of cytochrome P450 (CYP) and CYP-dependent enzymes were decreased, levels of reduced glutathione (GSH) and activities of UDP glucuronosyltransferase, gamma-glutamyltransferase and GSH S-transferase were increased. In contrast, coumarin produced few hepatic changes in the Syrian hamster. Following a single oral dose of 25 mg/kg [3-14C]coumarin, radioactivity was rapidly excreted by the rat and Syrian ha…
Ball Impact Position in Recreational Male Padel Players: Implications for Training and Injury Management
2021
Racket sports such as padel are characterized by the repetition of unilateral gestures, which can lead to negative adaptations like asymmetries or overuse musculoskeletal injuries. The purpose of this study was to determine the differences in ball impact positions (i.e., forward or backward of the center of gravity) in nine stroke types in a sample of forty-eight recreational male padel players. The sample included 14,478 shots corresponding to 18 matches from six tournaments. Forty-eight male padel players were classified into two groups according to their level: trained (n = 24) and novice (n = 24). Type of stroke and ball impact position were registered using a computerized motion tracki…
Comparison of Electromyographic Activity During Hip Extension Exercises Under Gravitational or Inertial Loading Conditions.
2021
Background: Hamstring injury prevention programs include strengthening, especially eccentric exercises using both gravitational and inertial loading. Inertial exercises are characterized by eccentric contractions of high intensity and velocity. This study aimed to analyze the muscular activation of the biceps femoris (BF), semitendinosus (ST), gluteus maximus (GM), and gracilis (GC) muscles during hip extension (HE) exercises performed under both gravitational and inertial loading conditions. Hypothesis: Inertial training would generate a greater activation of HE muscles than gravitational training. Study Design: Cross-sectional study. Level of Evidence: Level 4. Methods: Fifteen resistance…
Hypertonic saline solution and decompressive craniectomy for treatment of intracranial hypertension in pediatric severe traumatic brain injury.
2002
Experimental data 8 –11 and first clinical results in adults 12,13 suggest that hypertonic saline ( 1.0) may be highly effective in lowering ICP even when mannitol has lost its therapeutic potential after prolonged and repeated use. In children, only limited experience exists with the use of hypertonic saline solutions: a randomized prospective study in children with severe head injury compared the effects on ICP (increased to 15–20 mm Hg) of isotonic (0.9% NaCl) and hypertonic (3% NaCl) saline injections, demonstrating a beneficial effect of the hypertonic solution. 14 Another prospective randomized trial compared the effects of continuous infusion of either lactated Ringer’s solution (277…
Value and limits of computer-assisted tomography.
1980
Three years ago, at the VIIth International Congress of Radiology in Otorhinolaryngology, held in Copenhagen, the early impressive results of computer-assisted tomography (CAT) in otorhinolaryngology were presented. Since considerable technologic and diagnostic progress of CAT has taken place in the meantime, questions about the increase in CAT's value and the expansion of its limits are appropriate now. Computed and, in some cases, conventional tomograms of facial lesions are used in the discussion of these questions. There is no doubt of CAT's advance within the last few years; there are, however, limits of CAT to be emphasized: (a) coronal CAT might be uncomfortable (especially if the ga…
