OBJECTIVE: Long-term results of surgery for pelvic organ prolapse in terms of objective and subjective cure rates, postoperative complications and side-effects were studied retrospectively. METHODS: Two hundred and sixty-nine women underwent surgery between 1986 and 1988 and were invited to a follow-up visit in 1998-99. One hundred and twenty-eight (47%) women attended the follow-up. In the time between surgery and follow-up, 67 (25%) women had died. The medical records were reviewed for women not attending follow-up (n = 131), revealing a higher age and a more severe prolapse in the lost to follow-up group. RESULTS: The subjective cure rate, with cure of all symptoms of pelvic organ prolapse, was 46% (n = 59). The objective cure rate, with satisfactory anatomic outcome, was 56% (n = 72). If perfect results had been attained in the women who did not undergo follow-up examination, the subjective and objective cure rates would be 73% and 79%, respectively. Previous prolapse surgery, a traumatic delivery, urinary incontinence and a prolapse stage III or more seemed to be risk factors for an adverse outcome. CONCLUSIONS: In evaluating the cure rate of pelvic floor surgery not only the anatomic outcome should be studied but also the outcome in terms of side-effects and/or symptoms as resolved, persistent or new onset. An unsatisfactory anatomic outcome was not necessarily associated with symptoms. The modest cure rate after surgery may be due to the aggravation with time of pelvic floor disorder, this confounding the results of surgery. 相似文献

Medical students will influence future health care considerably. Their professional orientation while at medical school will be related to their future professional development. Therefore, it is important to study this group's view of the role of medical doctors, especially because Swedish health care is currently undergoing major changes and financial cut backs. Here, the theoretical framework was contemporary theories of competence development, which has shown that people's understanding of their work influences their actions. The aim of this study was to describe medical students' views of their future professional role in health care. In total, 57 fourth-year medical students at a Swedish university were asked to write a short essay about how they conceptualised their professional role in future health care. Fifty-three students (93%) replied. The essays were analysed qualitatively in three steps and four themes were subsequently identified: the professional role in change, organisation of health care, working conditions and the possibilities of having a balanced life. Some factors mentioned that would strongly influence the professional role were being team leader, increased specialisation, supporting the patient and computer science and technology. The students expressed ambiguous feelings about power and leadership. The results indicate that the students share a rather dark view of both the medical profession and health care, which seems to be related to stress and financial cut backs. Mentoring, time for reflection and changes in the curricula might be needed. 相似文献

AIMS: In experimental studies, morphine pharmacokinetics is different in the brain compared with other tissues due to the properties of the blood-brain barrier, including action of efflux pumps. It was hypothesized in this clinical study that active efflux of morphine occurs also in human brain, and that brain injury would alter cerebral morphine pharmacokinetics. METHODS: Patients with traumatic brain injury, equipped with one to three microdialysis catheters in the brain and one in abdominal subcutaneous fat for metabolic monitoring, were studied. The cerebral catheter locations were classified as 'better' and 'worse' brain tissue, referring to the degree of injury. Morphine (10 mg) was infused intravenously over a 10-min period in seven patients in the intensive care setting. Tissue and plasma morphine concentrations were obtained during the subsequent 3-h period with microdialysis and regular blood sampling. RESULTS: The area under the concentration-time curve (AUC) ratio of unbound morphine in brain tissue to plasma was 0.64 (95% confidence interval 0.40, 0.87) in 'better' brain tissue (P < 0.05 vs. the subcutaneous fat/plasma ratio), 0.78 (0.49, 1.07) in 'worse' brain tissue and 1.00 (0.86, 1.13) in subcutaneous fat. The terminal half-life and T(max) were longer in the brain vs. plasma and fat, respectively. The relative recovery for morphine was higher in 'better' than in 'worse' brain tissue. The T(max) value tended to be shorter in 'worse' brain tissue. CONCLUSIONS: The unbound AUC ratio below unity in the 'better' human brain tissue demonstrates an active efflux of morphine across the blood-brain barrier. The 'worse' brain tissue shows a decrease in relative recovery for morphine and in some cases also an increase in permeability for morphine over the blood-brain barrier. 相似文献

Patients with myelomeningocele may often suffer from severe spasticity. Surgical treatment of the underlying pathology such as hydromyelia and tethered cord may be successful, but failures are not uncommon. Those cases may offer a surgical challenge since further therapeutic options are limited. We present the case of a 7-year-old boy with myelomeningocele and related conditions suffering from severe spasticity and pain in his lower limbs. Surgical efforts with untethering and posterior fossa decompression failed to improve the symptoms. A test with 25 microg intrathecally delivered baclofen showed a total relief of spasticity and pain so that a pump for continuous baclofen delivery was implanted. During 32 months of follow-up, his spasticity has been under excellent control on 55-157 microg baclofen per day. Continuous delivery of intrathecal baclofen may be a surgical option to consider in patients with myelomeningocele and severe spasticity. 相似文献

The aim of this study was to explore individual and occupational factors possibly related to sensory thresholds in 484 middle-aged
men and women from the general population. Multivariate analyses were performed using a linear model including eight covariates
(age, body height, skin temperature, smoking habits, musculoskeletal symptoms during the last week before examination, isometric
muscle strength, aerobic capacity, and average physical work load during the last 15 years). Men and women were considered
separately in all analyses. Major findings were as follows: pressure pain thresholds increased with muscle strength; cold
perception thresholds on the foot improved with increasing skin temperature; vibration and warm perception thresholds on the
foot increased with age and body height; pressure pain threshold on the leg was decreased and vibration threshold on the hand
was increased in women with musculoskeletal symptoms; pressure pain thresholds were slightly increased in men reporting long-lasting
high physical work load. Significant sex differences were found for the majority of sensory thresholds, that is higher thresholds
in men. However, body height was found to be more important than gender for differences in vibration and warm perception thresholds
on the foot.

In 14 healthy female subjects, the effects of needle stimulation (acupuncture) on skin and muscle blood flow were investigated using a non-invasive custom-designed probe and photoplethysmography (PPG). In randomised order, 2–7 days apart, three modes of needle stimulation were performed on the anterior aspect of the tibia: superficial insertion (SF), insertion into the anterior tibial muscle (Mu), and insertion into the muscle including manipulation of the needle in order to elicit a distinct sensation of distension, heaviness or numbness (DeQi). Before intervention, the subjects rested for 30 min. After the intervention, the needle was left in situ for 20 min. Blood flow recordings were performed intermittently from 10 min prior to the intervention to the end of the trial. In a fourth session, serving as control, corresponding measurements were performed without any needle stimulation. Area under curve was calculated for 5-min periods prior to and after stimulation, respectively, and for the remaining 15-min period after stimulation. Compared to the control situation, muscle blood flow increased following both Mu and DeQi for 20 min, with the latter being more pronounced for the initial 5 min. Skin blood flow increased for 5 min following DeQi. However, no increase was found following SF. The DeQi stimulation was preceded by higher visual analogue scale ratings of anxiety prior to stimulation, which might have influenced skin blood flow to some extent. The results indicate that the intensity of the needling is of importance, the DeQi stimulation resulting in the most pronounced increase in both skin and muscle blood flow. 相似文献

Zusammenfassung Hintergrund: Fehler sind in der Medizin allgegenwärtig und stellen ein komplexes, multifaktorielles Geschen dar. Sie bedeuten ein erhebliches Risiko für den Patienten und haben enorme wirtschaftliche Konsequenzen für die Leistungserbringer. Systembezogener Ansatz: Unerwünschte Ereignisse haben ihre Ursache in der Regel nicht in einem einzelnen vorausgehenden Fehler. Ein effizientes Risk-Management-Konzept, das Bestandteil eines umfassenden Qualitätsmanagements, muss daher einen systembezogenen Ansatz verfolgen, der sich auf die Entdeckung und Analyse von Beinahe-Fehlern stützt und auf die Entwicklung von Abwehrmechanismen für die unerwünschten Folgen von Fehlern zielt. Die Frage "Wer ist schuld?" muss in den Hintergrund treten. Beinahe-Fehler (Near Misses) gehorchen den gleichen theoretischen und praktischen Bedingungen wir Indikatoren und bieten hierbei gegenüber der Messung von Fehlern und unerwünschten Ereignissen erhebliche methodische Vorteile. Abstract Background: Errors are a common problem in medicine and occur as a result of a complex process involving many contributing factors. Medical errors significantly reduce the safety margin for the patient and contribute additional costs in health care delivery. System Approach: In most cases adverse events cannot be attributed to a single underlying cause. Therefore an effective risk management strategy must follow a system approach, which is based on counting and analysis of near misses. The development of defenses against the undesired effects of errors should be the main focus rather than asking the question "Who blundered?". Analysis of near misses (which in this context can be compared to indicators) offers several methodological advantages as compared to the analysis of errors and adverse events. Risk management is an integral element of quality management. 相似文献

Twenty patients with acute traumatic hand injury were interviewed 8-20 days after the day of the accident. The aim of the study was to identify coping strategies, defined as thoughts or actions used by the hand-injured patients to manage stress factors and resulting emotions in the early stage. Stress factors were reported in an earlier study. The analyses of the interviews followed the first steps in the analytical process described in a modified model of grounded theory. Eleven different coping strategies were identified in the interviews. By "comparing with something worse", "positive thinking", "relying on personal capacity", "distancing" and "distracting attention" the patients tried to play down the seriousness of the problem or situation. Other coping strategies used by the hand-injured were "accepting the situation", "seeking social support", "maintaining control", "solving practical problems by oneself", "pain-relieving actions" and "active processing of the trauma experience." The findings of the study show how important it is to identify the patient's own way of coping with a stressful illness situation in order to give adequate psychosocial support. 相似文献

Thirty-five heart and kidney transplant patients were interviewed on five separate occasions during the first 2 yr after transplantation. The aim was to explore their experiences of phenomena that distinguish the transplantation from other kinds of medical treatment. The selection of informants was designed to permit comparisons between recipients with heart and kidney transplants and with living and necro-transplants. The qualitative analysis of the informants' reactions was focused on three themes; nine categories emerged. The first theme concerned general aspects of the donation and the donor and was differentiated in four categories: joy and sorrow, gratefulness and indebtedness, guilt, and inequity. The second theme related to the donor as a unique individual and included three categories: recognition and identification with the donor, influences of the donor, and relationship to the living donor. The third theme pertained to incorporation of the transplant and included two categories related to the naturalness of having a transplant, and the benevolent transplant. The informants' reactions were discussed in terms of primary and secondary processes. All informants were in an emotionally charged situation after transplantation and warded off anxiety-provoking impulses, most intensively during the first 6 months. Avoidance, suppression, and denial were the most common defence mechanisms, all of which seemed to be supported by the medical context. Other, more constructive strategies are suggested. The recipients' own interpretations of causes to possible personality changes are discussed. There were few differences between heart and necro-kidney patients concerning the reactions to the donation, the donor, and the transplant; the dividing line was more prominent between recipients with living and necro-transplants. 相似文献
