Symptomatic burden in myeloproliferative neoplasms is present in most patients and compromises quality of life. We sought to validate a broadly applicable 18-item instrument (Myeloproliferative Neoplasm Symptom Assessment Form [MPN-SAF], coadministered with the Brief Fatigue Inventory) to assess symptoms of myelofibrosis, essential thrombocythemia, and polycythemia vera among prospective cohorts in the United States, Sweden, and Italy. A total of 402 MPN-SAF surveys were administered (English [25%], Italian [46%], and Swedish [28%]) in 161 patients with essential thrombocythemia, 145 patients with polycythemia vera, and 96 patients with myelofibrosis. Responses among the 3 administered languages showed great consistency after controlling for MPN subtype. Strong correlations existed between individual items and key symptomatic elements represented on both the MPN-SAF and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30. Enrolling physicians' blinded opinion of patient symptoms (6 symptoms assessed) were highly correlated with corresponding patients'responses. Serial administration of the English MPN-SAF among 53 patients showed that most MPN-SAF items are well correlated (r > 0.5, P < .001) and highly reproducible (intraclass correlation coefficient > 0.7). The MPN-SAF is a comprehensive and reliable instrument that is available in multiple languages to evaluate symptoms associated with all types of MPNs in clinical trials globally. © 2011 by The American Society of Hematology.

Aims/hypothesis: We determined the shape of the metabolic memory of HbA1c and its contribution to retinopathy, as well as the importance of reducing HbA1c to prevent progression of retinopathy. Methods: The relative risk contribution of HbA1c values at different points in time to current progression of retinopathy was determined in the DCCT patients. Results: HbA1c 2 to 3 years earlier had the greatest relative risk contribution to current progression of retinopathy. HbA1c up to 5 years earlier made a greater contribution than current values, while values from 8 years earlier still had an important impact. When HbA1c had been at 8% for a long period and was subsequently lowered to 7%, the salutary effects did not begin to appear until 2 to 3 years after lowering. The hazard function for a constant level of HbA1c increased with time. The numbers needed to treat when reducing HbA1c from 8.3% to 8% from diagnosis was estimated to be 1,688 for the first 3 years and 13 for the period 9 to 12 years. Survival functions when reducing HbA1c from 8% to 7% show that pre-study glycaemic control dominates the effect on progression of retinopathy during the first years of a trial. Conclusions/interpretation: The most harmful effect of hyperglycaemia on progression of retinopathy in type 1 diabetes initially increases, but declines after roughly 5 years. The salutary effect of reducing HbA1c accelerates with time and becomes greater in clinical practice than has been previously understood. Clinical trials should preferably be designed for long periods or include patients with low previous glycaemic exposure to distinguish trial effects from those of the metabolic memory. © 2010 Springer-Verlag.

Background: Previous studies are contradictory in terms of the function, regeneration potential, insertion point, and crosssectional area of the semitendinosus and gracilis tendons after harvest for anterior cruciate ligament (ACL) reconstruction. Hypotheses: In the long term, the tendons will regenerate in most patients with a more proximal point of insertion, the crosssectional area of the tendons will be smaller compared with the nonoperated contralateral side, and the patients will be weaker in terms of the internal rotation and deep flexion of the knee. Study Design: Case series; Level of evidence, 4. Methods: Nineteen patients (9 women and 10 men) who had undergone ACL reconstruction a minimum of 6 years earlier, median 8.5 years (range, 6-11 years), with ipsilateral semitendinosus and gracilis autografts, underwent bilateral magnetic resonance imaging (MRI) of their knees. An experienced, independent musculoskeletal radiologist evaluated all MRI examinations. To evaluate the function, strength measurements in deep knee flexion and internal rotation were performed using an isokinetic strength-testing machine. Results: The semitendinosus tendon had regenerated in 17 of 19 (89%) patients and the gracilis tendon in 18 of 19 (95%) patients, as seen on MRI. There were no significant differences between the point of insertion for the tendons on the operated and nonoperated sides. The cross-sectional areas of the regenerated tendons revealed no significant differences compared with the normal tendons on the contralateral side, as measured 4 cm above the joint line. The patients were significantly weaker in terms of deep knee flexion at 60 and 180 deg/sec, but they were stronger in terms of internal rotation of the tibia at 60 deg/sec in the operated leg compared with the nonoperated leg. Conclusion: The semitendinosus and gracilis tendons regenerated in the majority of patients and regained an almost normal point of insertion on the pes anserinus a minimum of 6 years after harvest. The regenerated tendons had a cross-sectional area similar to that on the nonoperated contralateral side. The patients revealed a strength deficit in deep knee flexion but not in internal rotation. © 2012 The Author(s).

Background: The Swedish National Anterior Cruciate Ligament Register provides an opportunity for quality surveillance and research. Purpose: The primary objective was to recognize factors associated with a poorer outcome at an early stage. Study Design: Case series; Level of evidence, 4. Methods: Registrations are made using a web-based protocol with 2 parts: a patient-based section with self-reported outcome scores and a surgeon-based section, where factors such as cause of injury, previous surgery, time between injury and reconstruction, graft selection, fixation technique, and concomitant injuries are reported. The self-reported outcome scores are registered preoperatively and at 1, 2, and 5 years. Results: Approximately 90% of all anterior cruciate ligament (ACL) reconstructions performed annually in Sweden are reported in the register. Registrations during the period 2005-2010 were included (n = 17,794). After excluding multiligament reconstructions and reoperations, the male:female ratio was 57.5:42.5 for both primary (n = 15,387) and revision (n = 964) surgery. The cause of injury was soccer in approximately half the male patients and in one third of the female patients. All subscales of the Knee injury and Osteoarthritis Outcome Score (KOOS) were significantly improved 1, 2, and 5 years postoperatively in patients undergoing primary reconstructions. In terms of the KOOS, revisions did significantly less well than primary reconstructions on all follow-up occasions, and smokers fared significantly less well than nonsmokers both preoperatively and at 2 years. Patients who had concomitant meniscal or chondral injuries at reconstruction did significantly less well preoperatively and at 1 year in terms of most KOOS subscales compared with patients with no such injuries. At 5 years, a significant difference was only found in terms of the sport/recreation subscale. Double-bundle reconstructions revealed no significant differences in terms of all the KOOS subscales at 2 years compared with single-bundle reconstructions (114 double-bundle vs 5109 single-bundle). During a 5-year period, 9.1% (contralateral, 5.0%; revision, 4.1%) of the patients underwent a contralateral ACL reconstruction or revision reconstruction of the index knee. The corresponding figure for 15- to 18-year-old female soccer players was 22.0%. Conclusion: Primary ACL reconstruction significantly improves all the subscales of the KOOS. Young female soccer players run a major risk of reinjuring their ACL or injuring the contralateral ACL; revision ACL reconstructions do less well than primary reconstructions, and smokers do less well than nonsmokers. © 2012 The Author(s).

Introduction: Corticoid therapy is well-known to improve the symptoms of psoriasis. Addison's disease is an autoimmune disease which leads to a loss of cortisol production in the adrenal glands. This case report describes a patient with wide-spread psoriasis for 34 years who was cured when Addison's disease was detected and substitution to reach normal biological cortisol levels was introduced. Case Report: A 59-year-old man was diagnosed with Addison's disease. He had been tired for several years and had had difficulties in continuing his work. His brother had Addison's disease and recommended him to make a screen for the disease. Synacthen test diagnosed Addison's disease with a clear deficiency of cortisol production. After substitution with hydrocortisone the patient's constitution improved rapidly and he felt no longer tired during work. At the same time, all skin lesions of psoriasis disappeared as well as aches in several joints, both symptoms having been present for a couple of decades. Previously, salves of cortisol had been used to reduce the symptoms of psoriasis, but now, 1-2 years later, after the treatment of Addison's disease, no symptoms in the skin or joints have reoccurred. Conclusions: This report illustrates that Addison's disease, although a rare condition, should be kept in mind before treatment of psoriasis is started. Especially if other symptoms such as fatigue are present, a screening test of serum cortisol in the morning should be liberally made. The report also illustrates a need of examining corticoid levels in patients with psoriasis compared to the general population. Copyright © 2010 S. Karger AG.

Ten patients, age 60 (48-75 years), with osteoarthritis (OA) of the hip and 10 patients, age 82.5 (60-90 years), with fracture of the collum femoris (FCF; minimum Garden stage III) underwent an open biopsy procedure from the internal obturator tendon in conjunction with a total hip replacement. The histological evaluation revealed that all tendon samples in the OA group revealed scar tissue; the corresponding was found in 50% of patients in the FCF group (P=0.02). There were also more GAGs (P=0.023) and calcium deposits (P=0.001) in the samples from the OA group. The ultrastructural evaluation revealed fewer small and medium-sized fibrils (P=0.001) and more non-collagenous extracellular matrix (ECM) (P=0.003) in the OA group. Taken together, the samples from the internal obturator tendon in the OA group revealed a more degenerative appearance with more scar tissue, change in fibril diameter distribution and more non-collagenous ECM. Our findings suggest that OA and periarticular tendinopathy are closely linked. Further research is needed to determine whether musculotendinous changes in the deep rotators are sequelae of joint pathology, or a contributing factor in the development of degenerative joint change. © 2011 John Wiley & Sons A/S.

Background: Perioperative fluid therapy can influence postoperative hospital stay and complications after elective colorectal surgery. This trial was designed to examine whether an extremely restricted perioperative fluid protocol would reduce hospital stay beyond the existing fast-track hospital time of 7 days after surgery. Methods: Patients were randomized to restricted or standard perioperative intravenous fluid regimens in a single-centre trial. Randomization was stratified for colonic, rectal, open and laparoscopic surgery. Patients were all treated within a fast-track protocol (careful preoperative preparation, optimal analgesia, early oral nutrition and early mobilization). The primary endpoint was length of postoperative hospital stay. The secondary endpoint was complications within 30 days. Results: Seventy-nine patients were randomized to restricted and 82 to standard fluid therapy. Patients in the restricted group received a median of 3050 ml fluid on the day of surgery compared with 5775 ml in the standard group (P < 0·001). There was no difference between groups in primary hospital stay (median 6·0 days in both groups; P = 0·194) or stay including readmission (median 6·0 days in both groups; P = 0·158). The proportion of patients with complications was significantly lower in the restricted group (31 of 79 versus 47 of 82; P = 0·027). Vasopressors were more often required in the restricted group (97 versus 80 per cent; P < 0·001). Conclusion: Restricted perioperative intravenous fluid administration does not reduce length of stay in a fast-track protocol. © 2011 British Journal of Surgery Society Ltd.

The aim of this manuscript is to review the current knowledge in terms of retro-trochanteric pain syndrome, make recommendations for diagnosis and differential diagnosis and offer suggestions for treatment options. The terminology in the literature is confusing and these symptoms can be referred to as 'greater trochanteric pain syndrome', 'trochanteric bursitis' and 'trochanteritis', among other denominations. The authors focus on a special type of sciatica, i. e. retro-trochanteric pain radiating down to the lower extremity. The impact of different radiographic assessments is discussed. The authors recommend excluding pathology in the spine and pelvic area before following their suggested treatment algorithm for sciatica-like retro-trochanteric pain.

The aim of this prospective registry-based population study was to investigate the efficacy of extralevator abdominoperineal excision (ELAPE) regarding local recurrence rates within 3 years after surgery. Background: Local recurrence of rectal cancer is more common after abdominoperineal excision (APE) than after anterior resection. Extralevator abdominoperineal excision was introduced to address this problem. No largescale studies with long-term oncological outcomes have been published. Methods: All Swedish patients operated on with an APE and registered in the Swedish ColoRectal Cancer Registry 2007 to 2009 were included (n=1397) and analyzed with emphasis on the perineal part of the operation. Local recurrence at 3 years was collected from the registry. Results: The local recurrence rates at 3 years [median follow-up, 3.43 years (APE, 3.37 years; ELAPE, 3.41 years; not stated: 3.43 years)]were significantly higher for ELAPE compared with APE (relative risk, 4.91). Perioperative perforationwas also associatedwith anincreased riskof local recurrence (relative risk, 3.62). There was no difference in 3-year overall survival between APE and ELAPE. In the subgroup of patients with very low tumors (≤ 4cm from the anal verge), no significant difference in the local recurrence rate could be observed. Conclusions: Extralevator abdominoperineal excision results in a significantly increased 3-year local recurrence rate as compared with standard APE. Intraoperative perforation seems to be an important risk factor for local recurrence. In addition to significantly increased 3-year local recurrence rates, the significantly increased incidence of wound complications leads to the conclusion that ELAPE should only be considered in selected patients at risk of intraoperative perforation. © 2015 Wolters Kluwer Health, Inc.

Background - rationale for study: Atrial fibrillation is associated with an increased risk of stroke and mortality which is reduced by treatment with Warfarin. The most commonly used tool to assess the effectiveness of warfarin therapy is the time in therapeutic Range (TTR) of International Normalised Ratio (INR) 2.0-3.0. Our aim was to study whether INR variability, as assessed by the standard deviation of transformed INR (SDT INR) is more prognostically important than the TTR. Methods and Results: We studied 19,180 patients with atrial fibrillation on warfarin therapy to evaluate the association of TTR and that of SDT INR with all-cause mortality, stroke, bleeding and hospitalisation. The SDT INR was more prognostically important than the TTR. One standard deviation (SD) higher of SDT INR had a hazard ratio (HR) of 1.59 (95% CI 1.52-1.66) of mortality compared with 1.18 (95% CI 1.13-1.24) for one SD lower of TTR. For the other 3 events the HR was also higher for the SDT INR than for the TTR (stroke 1.30 (95% CI 1.22-1.39) vs. 1.06 (95% CI 1.00-1.13), bleeding 1.27 (95% CI 1.20-1.35) vs. 1.07 (95% CI 1.01-1.14), hospitalisation 1.47 (95% CI 1.45-1.49) vs. 1.13 (95% CI 1.10-1.15). When both metrics were included in the same analysis only the SDT INR was of significant predictive value. Conclusions: The SDT INR is a better predictor of mortality, stroke, bleeding and hospitalisation than the TTR in patients with atrial fibrillation receiving warfarin therapy. © 2011 Elsevier Ltd.
