Capsule Endoscopy versus Push Enteroscopy in Patients with Occult Gastrointestinal Bleeding
2003
Background Wireless capsule endoscopy is a new method enabling non-invasive diagnostic endoscopy of the entire small intestine. In this study we prospectively examined the diagnostic precision of capsule endoscopy compared with push enteroscopy in patients with occult gastrointestinal bleeding. Methods Between July 2001 and October 2002 we examined 48 patients with suspected disorders of the small intestine using capsule endoscopy. 33 patients with obscure bleeding (19 men, 14 women, mean age 58 +/- 23 years) were prospectively examined using capsule endoscopy and push enteroscopy. Results On average, the patients had been suffering from chronic gastrointestinal bleeding for 30 +/- 36 (1-12…
Safety and efficacy of an intra-oral electrostimulator for the relief of dry mouth in patients with chronic graft versus host disease: case Series
2013
Objectives: Patients with chronic graft-versus-host disease (cGVHD) often suffer from dry mouth and oral mucosal lesions. The primary objective of this study was to investigate the safety of an intra-oral electrostimulator (GenNarino) in symptomatic cGVHD patients. The secondary objective was to study the impact on the salivary gland involvement of cGVHD patients. Study Design: This paper presents a case series. The study included patients treated for 4 weeks, randomly assigned to the active device and then crossed-over to a sham-device or vice versa. The patients and clinicians were blind to the treatment delivered. Data regarding oral mucosal and salivary gland involvement were collected.…
Effects of mat characteristics on plantar pressure patterns and perceived mat properties during landing in gymnastics.
2011
Shock absorption and stability during landings is provided by both, gymnast ability and mat properties. The aims of this study were to determine the influence of different mat constructions on their energy absorption and stability capabilities, and to analyse how these properties affect gymnast's plantar pressures as well as subjective mat perception during landing. Six mats were tested using a standard mechanical drop test. In addition, plantar pressures and subjective perception during landing were obtained from 15 expert gymnasts. The different mats influenced plantar pressures and gymnasts' subjective perception during landing of gymnasts. Significant correlations between plantar pressu…
Hostility, unemployment and health status: testing three theoretical models.
2003
This study examined three theoretical models of hostility, health and life context. According to the psychosocial vulnerability hypothesis, there is an interaction between hostility and adverse conditions. The increased health risk in hostile individuals is assumed to stem from their lower ability to benefit from existing psychosocial resources. The second hypothesis, called here the social context model, considers adverse conditions as an antecedent of both hostility and health problems. The third model states that hostility is a predictor of being selected to adverse conditions involving risk to health (the selection hypothesis). The results from a survey of a population-based random samp…
Effect of overground vs treadmill running on plantar pressure: Influence of fatigue
2013
Abstract The differences produced when running on a treadmill vs overground may call into question the use and validity of the treadmill as a piece of equipment commonly used in research, training, and rehabilitation. The aim of the present study was to analyze under pre/post fatigue conditions the effect of treadmill vs overground on plantar pressures. Twenty-seven recreational runners (17 men and 10 women) ran on a treadmill and overground at two speeds: S 1 = 3.33 m/s and S 2 = 4.00 m/s, before and after a fatigue protocol consisting of a 30-min run at 85% of their individual maximal aerobic speed (MAS). Contact time (CT in seconds), peak pressure (PP in kPa), and relative load (RL in …
Modified fixation free plug technique using a new 3D multilamellar implant for inguinal hernia repair: a retrospective study of a single operator cas…
2013
Aim: Implant fixation, mesh shrinkage and poor quality of tissue ingrowth are unresolved issues in modern hernia repair. Many complications reported in the literature such as bleeding, nerve entrapment, hematoma, pain, discomfort, and testicular complications, are considered to be a direct results of implant fixation. This article describes the outcomes of a procedure carried out using a handcrafted implant that addresses the issues consequent to point fixation. Methods: This was a retrospective study on the short, medium and long-term results of placing a-modified, fixation free three-dimensional polypropylene implant in 61 patients who underwent inguinal hernia repair using a novel delive…
Performance of a new device for the clinical determination of light discomfort
2020
PURPOSE To assess the performance of a new device for the clinical determination of light discomfort on a large sample of healthy human subjects. METHODS A total of 489 subjects ranging from 20 to 70 years old (241 men, 248 women) were evaluated with the LUMIZ™ 100 to determine light discomfort. Repeatability was assessed by means of within-subject standard deviation, coefficient of variation (CoV), and intraclass correlation coefficient (ICC). Repeated measures ANOVA, Kruskal-Wallis, and correlation analysis were applied to test for differences between repeated measures, and effect of age on reliability. RESULTS Discomfort thresholds obtained are well distributed across the light intensity…
Reliability of knee extension and flexion measurements using the Con-Trex isokinetic dynamometer.
2007
The aim of this study was to evaluate the reliability of isokinetic and isometric assessments of the knee extensor and the flexor muscle function using the Con-Trex isokinetic dynamometer. Thirty healthy subjects (15 males, 15 females) were tested and retested 7 days later for maximal strength (isokinetic peak torque, work, power and angle of peak torque as well as isometric maximal voluntary contraction torque and rate of torque development) and fatigue (per cent loss and linear slope of torque and work across a series of 20 contractions). For both the knee extensor and the flexor muscle groups, all strength data - except angle of peak torque - demonstrated moderate-to-high reliability, wi…
A key role for abdominal ultrasound examination in "difficult" diagnoses of celiac disease.
2010
Purpose To evaluate the usefulness of abdominal ultrasound examination (US) for the diagnostic workup of cases of suspected CD involving negative serum antibodies and difficult diagnosis. Materials and methods 524 consecutive patients with symptoms of suspected CD underwent an extensive diagnostic workup. 76 (14 %) were excluded since they were positive for serum anti-tTG and/or EmA antibodies. 377 were excluded since they were diagnosed with something other than CD or did not have the alleles encoding for HLA DQ 2 or DQ 8. A diagnosis of CD with negative serum antibodies was probable in 71 patients who underwent abdominal US and duodenal biopsy for histology evaluation. Results Intestinal …
Reduction of HbA1c levels following nonsurgical treatment of periodontal disease in type 2 diabetics
2009
Objectives: A study was made of the effect of nonsurgical periodontal treatment upon blood glucose control in type 2 diabetics with periodontal disease. Study design: A pre-post repeated measures analytical design was used, with a PubMed search of the related articles published up until December 2008. Results: The improvement in glycosylated hemoglobin (HbA1c) after nonsurgical periodontal treatment on comparing the baseline (8.0290±1.5539) and final values (7.7806±1.5636) was 0.2483±0.1171, and proved statistically significant (p=0.042). Conclusions: A decrease in HbA1c was observed after treatment, thus indicating improved blood glucose control in type 2 diabetics with periodontal disease.
