Dislocation after total hip replacement is more common in the early, postoperative period. Postoperative intraarticular haematoma and remaining seroma fluid and/or weakened posterior soft tissue wall may be contributing factors. Our purpose was to compare and follow with sonography the resorption of the postoperative volume of intraarticular fluid/synovial oedema after total hip arthroplasty (THA)
Despite numerous studies documenting the association between cancer and venous thromboembolism (VTE), the reason for the excessive risk in certain cancers remains obscure. No large-scale studies have yet investigated the independent effects of cancer type, site and growth pattern. Between 1970 and 1982, 23,796 standardised autopsies were performed, representing 84% of all in-hospital deaths in an
Achilles tendinopathy is common and treatment with eccentric exercises seems promising. We designed a prospective randomized clinical trial to test the hypothesis that eccentric calf muscle exercises reduce pain and improve function in patients with Achilles tendinopathy. Forty-four patients were recruited from primary care (mean age: 45 years; 23 women; 65% active in sports) and randomized to thr
This dissertation deals with techniques for designing integrated amplifiers with high linearity. Amplifiers with operating frequencies from Audio to RF have been built. An enhanced feedback configuration, capable of very low distortion, is presented. Also presented is a statistical method for relating the distortion of a wideband signal to the total harmonic distortion (THD) of a single tone. Two
The aim of this study was to study the relationship between physician-assessed quality of life parameters, i.e., toxicity and physical performance, and patients' self-reports of their quality of life (QoL). QoL was assessed at baseline and before each treatment. using the EORTC QLQ-C30. The WHO performance score (PS) and toxicity were assessed in physician interviews. The correlations between the
Extended x-ray absorption fine structure measurements have been used to characterize the low-temperature, thermally induced structural relaxation of amorphous InP. We show reductions in both chemical and structural disorder associated with homopolar and heteropolar bonding, respectively, are operative during structural relaxation of this amorphous compound semiconductor. The latter is analogous to
Effluent from alkali extraction of chlorinated pulp was treated with ultrafiltration (UF). Three different ultrafiltration (UF) membranes were tested. The permeate from one of the UF membranes was further treated with reverse osmosis (RO). Titration curves for the permeates from the different UF and R0 membranes were determined. The concentration of charged compounds was calculated from the titrat
1. The topographical organization of mossy fibre input to the forelimb area of the paravermal C3 zone in cerebellar lobules IV and V was investigated in barbiturate-anaesthetized cats and compared with the previously described microzonal organization of climbing fibre input to the same part of the cortex. Recordings were made in the Purkinje cell and granule cell layers from single climbing fibre
The screen-printed four-electrode system was used as the amperometric transducer for determination of phenols and pesticides using immobilised tyrosinase. peroxidase. acetylcholinesterase and butyrylcholinesterase. Acetylthiocholine chloride was chosen as substrate for cholinesterases to measure inhibition by pesticides, hydrogen peroxide served as co-substrate for peroxidase to measure phenols. T
A prospective randomized double-blind trial was performed comparing conventional low-dose heparin with a LMWH fragment (Kabi 2165, Fragmin) for thromboprophylaxis in elective general abdominal surgical patients. The first dose of the fragment was given in the evening before surgery, and thereafter every evening. There were 1002 analyzable patients, 826 having received correct prophylaxis. Sixty th
Singular and supersingular finite rank perturbations of self-adjoint operators are studied using methods from renormalization theory for quantum fields. It is shown that the ideas from dimensional and Pauli-Villars regulatizations can be applied to determine uniquely certain finite rank supersingular perturbations. Approach is based on the regularization of homogeneous singular quadratic forms.
Popular Abstract in Swedish Under de senaste decennierna har en omfattande omstrukturering ägt rum av den psykiatriska vården. Verksamheterna vid de gamla mentalsjukhusen har avvecklats genom en omfattande nerdragning av slutenvårdplatser. Psykiatrins långtidssjuka patienter skulle återföras till det sociala liv de under lång tid varit avskärmade ifrån. I samband med omorganiseringen till den s kIn the past few decades a comprehensive restructuring of psychiatric care has taken place in Sweden. The activities of the traditional closed institutions have been curtailed through a drastic reduction in the number of beds available in such institutions. "Day treatment," has arisen as a new form of intensive outpatient care in the new, geographically localized psychiatric care of patients with l
Popular Abstract in Swedish Övervikt är ett av vår tids största hälsoproblem, kanske till och med det största. Det finns de som menar att redan idag utgör övervikt globalt sett en viktigare orsak till sjukdom än undernäring och infektionssjukdomar. Framtidsscenariot beskrivs som alarmerande. Folk kommer att i en tidigare aldrig skådad omfattning insjukna i överviktens följdsjukdomar. Medierna harThe prevalence of overweight and obesity is rising each year not only on a national but also on a global level. The future scenario is troublesome. The media are among the most important social institutions in influencing people’s knowledge, perceptions and actions. The media provide citizens with health messages and contribute thereby to their health development. This dissertation deals with two
Objective To compare the performances of 2 methods, telomerase repeat amplification protocol (TRAP) in situ and antibodies to the hTERT protein, in assessing telomerase activity. Study Design TRAP in situ and immunomercial antibody (NCL-hTERT) was performed on 54 body cavity effusions. The results were compared and correlated to diagnosis. Results Thirty-four effitsions from patients with verified
M. A. Persinger (2002) claimed that transcranial magnetic stimulation with weak, complex magnetic fields evokes mystical experiences. However, in a double-blind experiment, P. Granqvist, M. Fredrikson, P. Unge, A. Hagenfeldt, S. Valind., et al. (2005) found no effects of field exposure on mystical experiences (N = 89), though a minority of participants reported spontaneous mystical experiences. Fo
OBJECTIVES: To study bowel ischaemia in transfemorally placed endoluminal grafting (TPEG) for abdominal aortic aneurysms, and any relation to cytokine response or postoperative fever. DESIGN: Prospective not randomised. University hospital setting. MATERIAL: Fourteen cases of conventional surgery and 23 cases of endovascular technique for infrarenal abdominal aortic aneurysm repair. METHODS: Tonom
