Background: Maxillary sinus floor augmentation is a procedure that is indicated in cases when the volume of the posterior maxillary bone is inadequate. The goal of this treatment is to obtain sufficient amount of bone tissue in order to gain osseointegration of endosseous implants. Purpose: The purpose of this study was to conduct a clinical and histological analysis of calcium sulfate (CaS) as bone graft substitute in sinus floor augmentation. Material and Methods: Ten patients with edentulous maxillas were included in this study. They had moderate to severe atrophy of the posterior maxilla. Surgiplaster (Classimplant®, Rome, Italy) was used as graft material in the maxillary sinus and was covered by BioGide® (Geistlish Pharmaceutical, Wolhusen, Switzerland). After 4 months of graft healing, 40 dental implants were placed and a biopsy for histomorphometry was taken at these occasions. The specimens were viewed by light microscope, and the extent of bone regeneration and remaining graft material was evaluated. Radiographs were taken at the time of sinus augmentation and after 4 months of graft healing. Results: At the time of abutment surgery, one implant was considered as a failure and was consequently removed, giving a survival rate of 97.5% after 1 year of loading. Radiographs showed a mean of 26.5% shrinkage of the augmented area. A significant resorption of CaS was noted with a mean value of 8.8% of remaining graft material after 4 months of healing. The biopsies also revealed new bone formation with a mean value of 21.2% of the total biopsy area. Histology showed signs of an acellular substitution of CaS with bone-like tissue. Conclusion: The results of this study show that new bone regeneration occurs in the maxillary sinus after augmentation with CaS. This enabled successful placement, integration, and loading of dental implants in the posterior maxilla, as only 1 of 40 implants was lost during 1 year of follow-up. © 2009 Wiley Periodicals, Inc.

The future interferon-free treatment of hepatitis C virus (HCV) infection could include NS3 protease inhibitors (PIs) for potent pan-genotypic effect. We studied the prevalence of pre-existing PI resistance associated amino acid variants (RAVs) in 126 treatment-naive patient samples of HCV genotypes 1a, 2b and 3a, the most common genotypes in Sweden. The NS3 genes were each amplified by nested PCR method with degenerated primers to enable a broad genotype analysis. Population sequencing method was used, and the sequences were aligned with the NS3 sequence from HCV genotype 1a H77 strain. Interpretation of fold-change resistance to NS3 candidate drugs were done from already published phenotypic resistance data. The prevalence of known PI RAVs at baseline in genotype 1a was 28% (15/53), either single (V36L or Q80K/R) or combinations (T54A/S and V55A/I) of mutation(s). In genotype 2b, specific mutations like V36L, Q80G and S122R of viral NS3 protease gene were found in 100% (11/11). These may be the natural polymorphisms unique to genotype 2b. Similarly, specific mutations like V36L and D168Q were found uniquely in all 3a samples (30/30). The natural PI RAVs found in genotype 1a, although with relatively weak resistance, could still render up to 10-fold-resistance to the approved (boceprevir and telaprevir) and the 2nd generation PIs (faldaprevir and simeprevir). Moreover, the natural polymorphisms in genotype 2b (i.e. S122R) and 3a (i.e. D168Q), with inherent PI drug resistance of up to 20 and 700 fold respectively, would explain why current PIs are primarily directed against genotype 1. © 2013 Elsevier B.V.

BACKGROUND: The clinical effect of routine intracoronary thrombus aspiration before primary percutaneous coronary intervention (PCI) in patients with ST-segment elevation myocardial infarction (STEMI) is uncertain. We aimed to evaluate whether thrombus aspiration reduces mortality. METHODS: We conducted a multicenter, prospective, randomized, controlled, open-label clinical trial, with enrollment of patients from the national comprehensive Swedish Coronary Angiography and Angioplasty Registry (SCAAR) and end points evaluated through national registries. A total of 7244 patients with STEMI undergoing PCI were randomly assigned to manual thrombus aspiration followed by PCI or to PCI only. The primary end point was all-cause mortality at 30 days. RESULTS: No patients were lost to follow-up. Death from any cause occurred in 2.8% of the patients in the thrombus-aspiration group (103 of 3621), as compared with 3.0% in the PCI-only group (110 of 3623) (hazard ratio, 0.94; 95% confidence interval [CI], 0.72 to 1.22; P = 0.63). The rates of hospitalization for recurrent myocardial infarction at 30 days were 0.5% and 0.9% in the two groups, respectively (hazard ratio, 0.61; 95% CI, 0.34 to 1.07; P = 0.09), and the rates of stent thrombosis were 0.2% and 0.5%, respectively (hazard ratio, 0.47; 95% CI, 0.20 to 1.02; P = 0.06). There were no significant differences between the groups with respect to the rate of stroke or neurologic complications at the time of discharge (P = 0.87). The results were consistent across all major prespecified subgroups, including subgroups defined according to thrombus burden and coronary flow before PCI. CONCLUSIONS: Routine thrombus aspiration before PCI as compared with PCI alone did not reduce 30-day mortality among patients with STEMI. Copyright © 2013 Massachusetts Medical Society.

IMPORTANCE: A strategy using mechanical chest compressions might improve the poor outcome in out-of-hospital cardiac arrest, but such a strategy has not been tested in large clinical trials. OBJECTIVE: To determine whether administering mechanical chest compressions with defibrillation during ongoing compressions (mechanical CPR), compared with manual cardiopulmonary resuscitation (manual CPR), according to guidelines, would improve 4-hour survival. DESIGN, SETTING, AND PARTICIPANTS: Multicenter randomized clinical trial of 2589 patients with out-of-hospital cardiac arrest conducted between January 2008 and February 2013 in 4 Swedish, 1 British, and 1 Dutch ambulance services and their referring hospitals. Duration of follow-up was 6 months. INTERVENTIONS: Patients were randomized to receive either mechanical chest compressions (LUCAS Chest Compression System, Physio-Control/Jolife AB) combined with defibrillation during ongoing compressions (n = 1300) or to manual CPR according to guidelines (n = 1289). MAIN OUTCOMES AND MEASURES: Four-hour survival, with secondary end points of survival up to 6 months with good neurological outcome using the Cerebral Performance Category (CPC) score. A CPC score of 1 or 2 was classified as a good outcome. RESULTS: Four-hour survival was achieved in 307 patients (23.6%) with mechanical CPR and 305 (23.7%) with manual CPR (risk difference, -0.05%; 95%CI, -3.3%to 3.2%; P > .99). Survival with a CPC score of 1 or 2 occurred in 98 (7.5%) vs 82 (6.4%) (risk difference, 1.18%; 95%CI, -0.78%to 3.1%) at intensive care unit discharge, in 108 (8.3%) vs 100 (7.8%) (risk difference, 0.55%; 95%CI, -1.5%to 2.6%) at hospital discharge, in 105 (8.1%) vs 94 (7.3%) (risk difference, 0.78%; 95%CI, -1.3%to 2.8%) at 1 month, and in 110 (8.5%) vs 98 (7.6%) (risk difference, 0.86%; 95%CI, -1.2%to 3.0%) at 6 months with mechanical CPR and manual CPR, respectively. Among patients surviving at 6 months, 99%in the mechanical CPR group and 94%in the manual CPR group had CPC scores of 1 or 2. CONCLUSIONS AND RELEVANCE: Among adults with out-of-hospital cardiac arrest, there was no significant difference in 4-hour survival between patients treated with the mechanical CPR algorithm or those treated with guideline-adherent manual CPR. The vast majority of survivors in both groups had good neurological outcomes by 6 months. In clinical practice, mechanical CPR using the presented algorithm did not result in improved effectiveness compared with manual CPR. TRIAL REGISTRATIONL: Identifier: NCT00609778.

This retrospective cross-sectional study was carried out to study the association between different levels of hyponatremia and the occurrence of epileptic seizures in patients without a prior epilepsy diagnosis. We identified from the hospital database, 363 inpatients of a Swedish County hospital who between March 2003 and August 2006 were found to have serum sodium levels <125 mm. Medical records were reviewed and we identified 11 patients with seizures in conjunction with their hyponatremia. Seizures were the only neurologic manifestation of hyponatremia in patients with serum sodium levels >115 mm. Of 150 patients reviewed with serum sodium levels of 120-124 mm, one had a seizure. Using 120-124 mm as reference, odds ratios (95% confidence interval) for having seizures at serum sodium levels of 115-119 mm was 3.85 (0.40-37.53), 8.43 (0.859-82.85) at 110-114 mm, and 18.06 (1.96-166.86) at <110 mm. © 2011 International League Against Epilepsy.

Purpose: We describe the long-term prognosis in 257 first-time anterior shoulder dislocations (255 patients, aged 12–40 years) registered at 27 Swedish emergency units between 1978 and 1979. Methods: Half the shoulders were immobilised for 3–4 weeks after repositioning. Follow-ups were performed after two (questionnaire), five (questionnaire), 10 (questionnaire and radiology) and 25 (questionnaire and radiology) years in 227 patients (229 shoulders). Twenty-eight patients died during the 25 years of observation. Results: Early movement or immobilisation after the primary dislocation resulted in the same long-term prognosis. Recurrences increased up to 10 years of follow-up, but, after 25 years, 29 % of the shoulders with ≥2 recurrences appeared to have stabilised over time. Arthropathy increased from 9 % moderate to severe and 11 % mild at 10 years, to 34 % moderate to severe and 27 % mild after 25 years. Alcoholics had a poorer prognosis with respect to dislocation arthropathy (P < 0.001). Age <25 years and/or bilateral instability represent a poorer prognosis, where stabilising surgery is necessary in every second shoulder. Fracture of the greater tuberosity means a good prognosis, and we have found no evidence that athletic activity, gender, a Hill–Sachs lesion and minor rim fractures had any prognostic impact. During the 25 years in which these patients were followed, 28/255 died (11 %), representing a mortality rate (SMR) that was more than double that of the general Swedish population (P < 0.001). Conclusion: Almost half of all first-time dislocations at the age of <25 years will have stabilising surgery and two-thirds will develop different stages of arthropathy within 25 years. © 2016, European Union.

The aim of our study was to estimate uptake of prostate-specific antigen (PSA) testing in an entire country, including time trends and geographical differences. Data from the Swedish Cancer Register on prostate cancer incidence between 1980 and 2007 and published data from the Gothenburg branch of the European randomized study of screening for prostate cancer (ERSPC), a population-based PSA screening study, were used in two models of changes in incidence of prostate cancer as a proxy for uptake of PSA testing in all 24 Swedish counties. The estimated annual PSA testing, irrespective of previous years' exposure, reached a peak of 12% of all men in 2004 and decreased thereafter to 6% in 2007 and varied from less than 5 to 20% between counties. Under the assumption that men who underwent annual PSA testing were previously unexposed to PSA testing, the cumulated uptake of PSA testing in men aged 55-69 years in Sweden increased from zero in 1997 to 56% in 2007. Our study shows that it is possible to estimate uptake of PSA testing in the population from the prostate cancer incidence pattern. There were large geographical variations in uptake of PSA testing despite a uniform health care system in Sweden and there was a substantial increase in the uptake of PSA testing during the study period, despite that there were no national recommendations for PSA-based prostate cancer screening.

Background: In 2 Swedish hospitals, 88 consecutive shoulders underwent Bankart repair (B), and 97 consecutive shoulders underwent Bristow-Latarjet repair (B-L) for traumatic anterior recurrent instability. Materials and methods: Mean age at surgery was 28 years (B-L group) and 27 years (B group). All shoulders had a follow-up by letter or telephone after a mean of 17 years (range, 13-22 years). The patients answered a questionnaire and completed the Western Ontario Shoulder Index (WOSI), Disability of Arm Shoulder and Hand (DASH), and SSV (Simple Shoulder Value) assessments. Results: Recurrance resulted revision surgery in 1 shoulder in the B-L group and in 5 shoulders in the B group (P = .08). Redislocation or subluxation after the index operation occurred in 13 of 97 B-L shoulders and in 25 of 87 of B shoulders (after excluding 1 patient with arthroplasty because of arthropathy, P = .017) Of the 96 Bristow shoulders, 94 patients were very satisfied/satisfied compared with 71 of 80 in the B series (P = .01). Mean WOSI score was 88 for B-L shoulders and 79 for B shoulders (P = .002) B-L shoulders also scored better on the DASH (P = .002) and SSV (P = .007). Patients had 11° loss of subjectively measured outward rotation with the arm at the side after B-L repair compared with 19° after Bankart (P = .012). The original Bankart, with tunnels through the glenoid rim, had less redislocation(s) or subluxation(s) than shoulders done with anchors (P = .048). Conclusions: Results were better after the Bristow-Latarjet repair than after Bankart repairs done with anchors with respect to postoperative stability and subjective evaluation. Shoulders with original Bankart repair also seemed to be more stable than shoulders repaired with anchors. © 2011 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Transfer of the coracoid (Bristow-Latarjet [B-L]) is used to stabilize anterior shoulder instability. We report the long-term results of our first 31 operations with this method. Materials and methods: Thirty-six patients (mean age, 26.7years) had a B-L repair from 1977 to 1979. Five patients died, and during 2012 to 2013, the remaining 31 shoulders had a follow-up with questionnaire, physical examination, Western Ontario Shoulder Instability Index, Subjective Shoulder Value, Subjective Assessment of Shoulder Function, subjective assessment of loss of motion, and radiologic imaging. Results: One patient required revision surgery because of recurrence and another because of repeat dislocation. Six patients reported subluxations. Eighteen patients (58%) were very satisfied, and 13 (42%) were satisfied. The mean Western Ontario Shoulder Instability Index score (100 possible) was 85, and the median score was 93. According to Samilson-Prieto classification of arthropathy of the shoulder, 39% were classified as normal, 27% as mild, 23% as moderate, and 11% as severe. The classification of arthropathy varied with observers and radiologic views. Age younger than 22years at the primary dislocation meant less arthropathy at follow-up (. P=.045). Conclusion: The degree of arthropathy 33 to 35years after the B-L repair seems to follow the natural history of shoulder dislocation with respect to arthropathic joint degeneration. Postoperative restriction of external rotation does not increase later arthropathy. © 2015 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: We evaluated the results of the May modification of the Bristow-Latarjet procedure (" coracoid in standing position" ) in 319 shoulders with respect to (1) coracoid healing and position and (2) surgical treatment of the joint capsule. Methods: From 1980 until 2004, all shoulders with a Bristow-Latarjet repair were registered at our hospital. This study consists of 3 different cohorts with respect to follow-up. Series 1, 118 shoulders operated on during 1980 through 1985, had 15 years' radiographic and clinical follow-up. Series 2, 167 shoulders that had surgery during 1986 through 1999, underwent retrospective follow-up by a questionnaire and scores-Western Ontario Shoulder Instability Index; Disabilities of the Arm, Shoulder and Hand; and Subjective Shoulder Value-after 10 to 23 years. Series 3, 34 shoulders treated during 2000 through 2004, with an added modified Bankart repair (" capsulopexy" ) in 33 shoulders, were prospectively followed up for 5 to 8 years with the same questionnaire and scores as series 2. Results: Of 319 shoulders, 16 (5%) had 1 or more redislocations and 3 of these (1%) had revision surgery because of remaining instability. One or more subluxations were reported in 41 shoulders (13%). The worst scores were found in 16 shoulders with 2 or more subluxations (P < .001). Radiographs showed bony healing in 246 of 297 shoulders (83%), fibrous union in 34 (13%), migration by 0.5 cm or more in 14 (5%), and no visualization in 3 (1%). Five of six shoulders that had the transplant positioned 1 cm or more medial to the glenoid rim had redislocations (83%, P = .001). Shoulders with migrated transplants did not differ from those with bony or fibrous healing with respect to redislocations and subluxations. When just a horizontal capsular shift was added to the transfer, the recurrence rate (redislocations or subluxations) decreased, with 2 of 53 (4%)compared with 37 of 208 (18%) with just anatomic closure of the capsule (P = .005), and the Western Ontario Shoulder Instability Index score improved (92 vs 85.6, P = .048). In total, for 307 of 319 shoulders (96%), patients were satisfied or very satisfied at final follow-up. Conclusion: The open Bristow-Latarjet procedure yields good and consistent results, with bony fusion of the coracoid in 83%. A position of the coracoid 1 cm or more medial to the rim meant significantly more recurrences. The rate of recurrences decreased and subjective results improved when a horizontal capsular shift was added to the coracoid transfer. © 2012 Journal of Shoulder and Elbow Surgery Board of Trustees.
