Perineal neuromuscular fatigue.

AIM: The physiology of urinary continence during stress is complex and the role of passive and active mechanisms remains unclear. Coughing leads to a contraction of urethral rhabdomyosphincter and pelvic floor muscles leading to a positive urethro-vesical gradient and continence. Neuromuscular fatigue can involve all striated muscles, including rhabdomyosphincter, peri-urethral and pelvic floor muscles. This article reviews results of studies assessing perineal muscular fatigue in urinary incontinence. MATERIALS AND METHODS: A systematic review of the literature (Medline, Pascal and Embase) with use of the MESH keywords fatigue, stress, urinary incontinence, pelvic floor, urethra, urethral pressure, and muscle. RESULTS: Animal models have shown that the pelvic muscles (iliococcygeus and pubococcygeous) exhibit more neuromuscular fatigue than classical skeletal striated muscles (i.e. soleus muscle). Although the human external urethral sphincter is considered to be a highly fatigue-resistant muscle with its high proportion of slow muscle fibers, repeated coughing seems to lead to decreased urethral pressure in numerous women affected with stress urinary incontinence. In this case, "urethral fatigue" might be a possibility. CONCLUSIONS: Although few studies have focused on perineal muscular fatigue, such increased fatigue in pelvic floor muscles may play a role in the pathophysiologic features of stress urinary incontinence in women.

[Psychobehavioural assessment for chronic low back pain].

INTRODUCTION: Psychobehavioural assessment may be a complementary approach to assess response to treatment for pain and disability in patients with low back pain. OBJECTIVES: To assess the correlation between psychobehavioural factors and pain and disability in patients with chronic low back pain in France. METHODS: We asked 83 patients with chronic low back pain to complete questionnaires during a primary care consultation by a general practitioner. Pain was measured by a visual analog scale (VAS), disability by the Quebec Back Pain Disability Scale and psychobehavioural factors by the Fear-Avoidance Beliefs Questionnaire (FABQ) and the Coping Strategy Questionnaire (CSQ). RESULTS: Pain was poorly correlated with anxiety (R = 0.36) and scores on the FABQ 1 (R = 0.46) and FABQ 2 (R = 0.30) and not correlated with depression (R = 0.22), duration of pain evolution (R = 0,10) and body mass index (R = 0.12). The duration of stopping work was poorly correlated with disability (R = 0.35) and FABQ 1 score (R = 0.43) and not correlated with pain (R = 0.11), anxiety (R = 0.11), depression (R = 0.26) and FABQ 2 score (R = 0.23). Disability was poorly correlated with scores on the FABQ 1 (R = 0.45) and FABQ 2 (R = 0.3), anxiety (R = 0.39) and depression (R = 0.47) and not correlated with pain (R = 0.25). Dramatization is the only way to cope with pain and was correlated with pain (R = 0.34), scores on the FABQ 1 (R = 0.47) and FABQ 2 (R = 0.43), disability (R = 0.38), anxiety (R = 0.44) and depression (R = 0.46). The use of prayer was poorly correlated with FABQ 1 score (R = 0.37) and anxiety (R = 0.30). Distraction was poorly correlated with scores on the FABQ 1 (R = 0.40) and FABQ 2 (R = 0.30). No strategy was correlated with duration of pain and stopping work. DISCUSSION-CONCLUSION: All the correlation assessments with psychobehaviour factors are weak. So evaluating each of these parameters will be interesting. Duration of pain was not correlated with increasing pain or change in behavioural strategy. Psychobehavioural factors are more invalidating than pain. More study is needed to assess psychobehavioural therapies in patients with low back pain.

[Constituted adult equine from the ankle: surgical treatment by Ilizarov external fixator].

INTRODUCTION: Ilizarov's external fixator indications are classically used in children to lengthen the lower limbs. This technique is used for adults to gradually correct articular limitations, especially in the knee, ankle and foot. METHOD AND RESULTS: We report a case of a 53-year-old patient with distal microangiopathy of the lower limbs leading to amputation of the toes and a bilateral, direct, irreducible, isolated equine feature? from the back foot to 0/50/60 degrees? on retraction of the Achilles tendon. The aim of patient management was to regain walking ability. Because of vascular and cutaneous fragility, the classical surgical treatment was contra-indicated. Progressive reduction by Ilizarov's external fixator was tried. Dorsal inflection was obtained by twice-daily screwing until a radiological angle of 90 degrees was obtained between the tibia and talus. At ten weeks post-surgery, the dorsal voluntary inflection ankle amplitude was symmetrical to 0/10/60 degrees. The patient walked with orthopaedic shoes compensating for the few degrees of residual equine. DISCUSSION: Correction of adult equine without osseous deformation by Ilizarov's external fixator should be considered when conventional surgery is contra-indicated.

[Clinical evaluation of female urinary incontinence].

EXAMINATION: Clinical evaluation of stress and urge incontinence is always necessary before therapeutic decisions. Full bladder examination may reveal stress incontinence during cough when cervico-urethral hypermobility is suspected, and leak during Vasalva manoeuvre when incontinence is due to intrinsic sphincter deficiency. OBJECTIVE SCORES: Pad test objectives the quantitative importance of incontinence. Symptom scores allow intra and inter individual comparisons. Psychosocial implications are studied with specific quality of life scales. They allow better therapeutic strategies in the management of urge and stress urinary incontinence. Objective evaluation of the different treatments and medico-economic approach of incontinence are thus possible.

Cystic rheumatoid arthritis with Felty's syndrome and ankylosing spondylitis.

A 63-year-old man with strictly axial ankylosing spondylitis since the age of 28 years had a seven-year history of cystic seronegative rheumatoid arthritis with Felty's syndrome. Cysts were present in the hands, feet, wrists, shoulders, hips, one elbow, and one knee. There was no evidence of juxtaarticular demineralization, joint space loss, erosions, or joint destruction. Rheumatoid pannus was demonstrated within the cysts, particularly at the hip, ruling out cystic hip disease due to ankylosing spondylitis. HLA typing demonstrated the B27 and DR4 haplotypes. HLA B27 may be associated with a worse prognosis of rheumatoid hip involvement.

Nursing students' learning styles: a comparison of degree and non-degree student approaches to studying.

This research utilised the Lancaster inventory to investigate the approaches to studying of a group of nurse learners (n = 32) from a college of nursing and midwifery and a group of nursing undergraduates (n = 23) from an institution of higher education. It was hoped that the research would cast some light on whether the two groups approach their studying in similar or different ways, since these approaches may dictate success in educational ventures. The results indicated no statistically significant differences between the two learner groups' approaches to studying.
