The Appendix as a Continence Mechanism
1992
Although we have progressed very well in creating large capacity, low pressure reservoirs, the construction of a simple and reliable continent outlet still remains a problem. The appendix vermiformis serves well as a continence mechanism for either the bladder or intestinal reservoirs for urine. The different surgical techniques described in the literature are reviewed and discussed in this context. Moreover, we report on our clinical and experimental results of using the appendix during the Mainz pouch procedure for continent urinary diversion.
Eight months of physical training in warm water improves physical and mental health in women with fibromyalgia: a randomized controlled trial.
2008
Objective To evaluate the feasibility of 8 months of supervised exercise therapy in warm water and its effects on the impact of fibromyalgia on physical and mental health and physical fitness in affected women. Methods Thirty women with fibromyalgia were randomly assigned to an exercise therapy group (n = 15) or a control group (inactive) (n = 15). The impact of fibromyalgia on physical and mental health was assessed using the Fibromyalgia Impact Questionnaire and the anxiety state with State-Trait Anxiety Inventory. Physical fitness was measured using the following tests: Canadian Aerobic Fitness; hand-grip dynamometry; 10-metre walking; 10-step stair-climbing and blind 1-leg stance. Resul…
Influence of aquatic training on the motor performance of patients with haemophilic arthropathy
2009
Thirteen patients with haemophilia A took part in this study voluntarily. They underwent an aquatic training programme over a 9-week period (27 sessions; three sessions per week; 1 h per session). Their motor performance was assessed by the following cardio-respiratory and mechanical variables before and after the training programme: oxygen uptake (VO(2), mL min(-1)), relative oxygen uptake (rel VO(2), mL min(-1).kg(-1)), carbon dioxide (CO(2), mL min(-1)), respiratory quotient (R), heart rate (bpm) and the distance covered in 12 min (the Cooper test, m). Nine patients successfully completed the intervention and measurement protocols without bleeding or other adverse events. After the propo…
Health-Promoting Effects of Serial vs. Integrated Combined Strength and Aerobic Training
2016
Combined strength and aerobic training programs are widely used for improving markers of physical fitness and health. We compared the efficiency of a serial and an integrated combined training program on health and overall fitness in middle-aged females. 54 females (46.7±4.5yrs) were assigned to a serial (SCG) or an integrated (ICG) combined training group or to a control group (CG). The SCG and ICG performed a 3-month training combining aerobic dance and calisthenics. The 2 training programs differ in the sequence of aerobic and strength exercises. SCG performed the strength exercises prior to aerobic; in ICG, the aerobic and strength exercises were altered in a predetermined order. Body c…
Difference in Mortality Risk in Elderly People with Bronchial Obstruction Diagnosed Using a Fixed Cutoff or the Lower Limit of Normal of the FEV1/FVC…
2017
Background: Whether a fixed cutoff or the lower limit of normal of the FEV1/FVC ratio should be used to diagnose bronchial obstruction is still a matter of debate. This issue is particularly important for elderly people. Objectives: We used equations applicable up to 90 years of age to evaluate the mortality of elderly people diagnosed with bronchial obstruction using either a fixed cutoff of 0.7 or the lower limit of normal (LLN). Methods: Participants in the SaRA (Salute Respiratoria nell'Anziano, Italian for "Respiratory Health in the Elderly") study were grouped as follows: FEV1/FVC ≥0.7 and ≥ LLN (n = 535: F-/L-), FEV1/FVC <0.7 but ≥ LLN (n = 118: F+/L-), and FEV1/FVC <0.7 and < LLN (n…
Mild to moderate chronic airways disease does not carry an excess risk of cognitive dysfunction
2003
Whether chronic obstructive pulmonary disease (COPD) carries a risk of cognitive dysfunction prior to the onset of arterial hypoxemia is not known. Our objective was to assess both the prevalence and main correlates of subclinical cognitive dysfunction in older patients with non-hypoxemic COPD.Home-dwelling non-demented subjects over 64 years of age consecutively attending 24 outpatient Departments of Respiratory Medicine or Geriatrics because of COPD (N = 233), asthma (N = 203), non-obstructive bronchitis (N = 92) or chronic non-respiratory and non-dementing diseases (controls, N = 1080) underwent a multidimensional assessment. Cognitive status was assessed by the Mini-Mental State Examina…
Isolation and characterization of hydrocarbonoclastic bacteria from Algerian coast
2017
Backgrounds The contamination of marine environments by hydrocarbons represents a global concern with consequences on ecosystems and human health. The removal of HC by physical and/or chemical methods is expensive and disrespectful of the environment. The use of HC degrading bacteria is a good alternative for environmental remediation (bioremediation). Objectives The Algerian coastline is exposed to several types of pollutions, including hydrocarbons. The aim was to explore the bioremediation potential of its contaminated harbors for the first time. Methods To identify the hydrocarbon degrading bacteria seawater samples were collected in Sidi fredj harbor (Algeria) and used to enrichment cu…
Modelling of proton and metal exchange in the alginate biopolymer.
2005
Acid-base behaviour of a commercial sodium alginate extracted from brown seaweed (Macrocystis pyrifera) has been investigated at different ionic strengths (0.1or=I/mol l(-1)or=1.0) and in different supporting electrolytes (Et4NI, NaCl, KCl, LiCl, NaCl+MgCl2), with the aim of examining the influence of ionic medium on the proton-binding capacity and of quantifying the strength of interaction with light metal ions in the perspective of speciation studies in natural aqueous systems. Potentiometric ([H+]-glass electrode) and titration calorimetric data were expressed as a function of the dissociation degree (alpha) using different models (Henderson-Hasselbalch modified, Högfeldt three parameter…
Nasal IgE in subjects with allergic and non-allergic rhinitis
2020
Abstract Purpose The prevalence of "ocal allergic rhinitis" within individuals suffering from perennial rhinitis remains uncertain, and patients usually are diagnosed with non-allergic rhinitis. The aim of this study was to evaluate the prevalence of a potential "local allergic rhinitis" in subjects suffering from non-allergic rhinitis in a non-selected group of young students. Methods 131 students (age 25.0 ± 5.1 years) with a possible allergic rhinitis and 25 non-allergic controls without rhinitis symptoms (age 22.0 ± 2.0 years) were recruited by public postings. 97 of 131 students with rhinitis were tested positive (≥3 mm) to prick testing with 17 frequent allergens at visit 1. Twenty-fo…
Alveolar Gas Mixing in Chronic Pulmonary Hyperinflation
1991
It is well known that in chronic pulmonary hyperinflation defects in intrapulmo-nary gas mixing and in V/Q ratio are likely to occur.
