Background Hand eczema (HE) is a frequent, long-lasting disease with both personal and societal repercussions. Consequently, more information is needed on factors that maintain symptoms. Objectives In this study, patients with HE were followed for 6 months from the first visit to a dermatologist to identify factors associated with severe disease and a poor prognosis. Methods Study participants were 799 patients with HE from nine dermatological clinics in Denmark. Severity assessment of the HE was done at baseline and at the 6-month follow-up using the Hand Eczema Severity Index (HECSI) and by patients using a self-administered photographic guide. Additional information was obtained from a baseline questionnaire. Results At baseline, 60·3% assessed their HE as moderate to very severe using the self-administered photographic guide compared with 36·1% at follow-up. The mean HECSI value decreased from 19·9 points at baseline to 11·2 points at follow-up ( P < 0·001). In a multivariable logistic regression analysis, statistically significant associations with severe HE at baseline were older age ( P < 0·001), atopic dermatitis ( P = 0·01) and ≥ 1 positive patch test ( P < 0·001). Being an unskilled worker was a predictor for a poor prognosis at follow-up ( P = 0·04), and the presence of frequent symptoms during the previous 12 months was associated with severe initial disease ( P = 0·02) and a poor prognosis ( P = 0·04). Conclusions Overall, the disease had improved 6 months after the dermatological examination: nevertheless, many patients continued to have significant symptoms. Dermatologists should pay special attention to patients with frequent eruptions and to unskilled workers. [ABSTRACT FROM AUTHOR]

Preliminary case reports have suggested an association between Campylobacter jejuni infection and occurrence of perimyocarditis. In the present study we analysed the incidence of perimyocarditis requiring hospitalization in a Danish cohort of 6,204 patients with Campylobacter-positive stool cultures and compared it to the incidence in a matched control cohort comprising 62,040 subjects. We found no cases of pericarditis in the Campylobacter population and an incidence rate of 3.2 [95% confidence interval (CI): 0.8–12.9] per 100,000 person-years in the control population. The incidence rate of myocarditis was 16.1 (95% CI: 2.3–114.4) per 100,000 person-years in the Campylobacter population compared to 1.6 (95% CI: 0.2–11.4) per 100,000 person-years in the control cohort. We found no statistically significant difference in perimyocarditis between the two groups. [ABSTRACT FROM AUTHOR]

This national population-based study was conducted as part of the development of a national automated surveillance system for hospitalacquired bacteraemia and ascertains the utilization of blood cultures (BCs). A primary objective was to understand how local differences may affect interpretation of nationwide surveillance for bacteraemia. From the Danish Microbiology Database, we retrieved all BCs taken between 2010 and 2013 and linked these to admission data from the National Patient Registry. In total, 4 587 295 admissions were registered, and in 11%, at least one BC was taken. Almost 50% of BCs were taken at admission. The chance of having a BC taken declined over the next days but increased after 4 days of admission. Data linkage identified 876 290 days on which at least one BC was taken; 6.4% yielded positive results. Ten species, Escherichia coli, Staphylococcus aureus, Klebsiella pneumoniae, Streptococcus pneumoniae, Enterococcus faecium, Enterococcus faecalis, Pseudomonas aeruginosa, Candida albicans, Enterobacter cloacae and Klebsiella oxytoca, accounted for 74.7% of agents for this purpose classified as pathogenic. An increase in BCs and positive BCs was observed over time, particularly among older patients. BCs showed a seasonal pattern overall and for S. pneumoniae particularly. A predominance of male patients was seen for bacteraemias due to S. aureus, E. faecium and K. pneumoniae. Minor differences in BCs and positive BCs between departments of clinical microbiology underpin the rationale of a future automated surveillance for bacteraemia. The study also provides important knowledge for interpretation of surveillance of invasive infections more generally. [ABSTRACT FROM AUTHOR]

Introduction: Patients with generalised joint hypermobility, including knee hypermobility (GJHk), often experience knee pain and are typically managed with low-intensity strength training and/or proprioceptive training as part of standard care. However, not all patients experience satisfactory outcomes. High-load strength training may offer additional benefits, such as increased muscle cross-sectional area, neural drive and tendon stiffness, which may reduce pain and improve active knee joint stability during movement tasks and daily activities. So far, no randomised controlled trials (RCTs) have compared high-load strength training with traditional treatment strategies (standard care) for this patient group., Methods and Analysis: In this RCT, we aim to recruit patients with GJHk and knee pain from primary care physiotherapy clinics in the Region of Southern Denmark and via social media. Patients with competing injuries or experience with high-load strength training will be excluded. Patients will be randomised (1:1 ratio) to either 2 weekly sessions of high-load strength training or standard care for 12 weeks. The primary outcome is self-reported knee pain during an activity nominated by the patient as the most aggravating for their present knee pain measured using the Visual Analogue Scale for Nominated Activity (VAS NA , 0-100; 0=no pain and 100=worst imaginable pain). This will be collected at baseline, 6 weeks, 12 weeks and 12 months. Secondary outcomes include self-reported knee function and adverse events (collected at baseline, 12 weeks and 12 months), objective measurements including a 5-repetition maximum single-leg press, proprioception and single-leg-hop for distance (collected at baseline and 12 weeks), and a range of other outcome measures such as fear of movement, tendon stiffness and global perceived effect. We aim to recruit 90 patients in total to detect a 10 mm group difference in the primary outcome with 80% power., Ethics and Dissemination: This study was funded by Independent Research Fund Denmark (grant number 2034-00088B) on 14 June 2022; the Regional Committees on Health Research Ethics for Southern Denmark approved it (S-20230050) on 30 August 2023. The first recruitment site opened on 15 February 2024, and the final results will be submitted to a peer-reviewed journal to inform rehabilitation strategies for symptomatic GJHk.Protocol version 1, dated 4 July 2024., Trial Registration Number: NCT06277401., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Hand hygiene (HH) among health care workers (HCWs) is crucial in preventing infections in nursing homes. However, HH compliance (HHC) among HCWs remains low. This study aimed to investigate the effect of feedback lights on HCWs' HHC., Methods: A 5-month interventional study was conducted in 3 wards in a nursing home in Denmark. During the intervention period, a green light with a smiley appeared on the alcohol-based hand rub (ABHR) dispensers when HCWs used the ABHR, acknowledging HCWs for using the ABHR. HHC was monitored using an automatic HH monitoring system (AHHMS)., Results: A total of 64 HCWs were enrolled. The AHHMS collected 23,696 HH opportunities in apartments and dirty utility rooms. Overall, HHC in the apartments increased from 50% at baseline (95% CI: 48, 53) to 56% (95% CI: 54, 58) during the intervention. However, the increased HHC level was not sustained during follow-up., Conclusions: The AHHMS enabled the assessment of the intervention. We found a significant effect of light-guided feedback in the apartments. However, the increased HHC was not sustained after the light was switched off., (Copyright © 2024 The Authors.

The emergence of bloodstream infections (BSI) caused by vancomycin-resistant Enterococci (VRE) has caused concern. Nonetheless, it remains unclear whether these types are associated with an excess risk of severe outcomes when compared with infections caused by vancomycin-susceptible Enterococci (VSE). This cohort study included hospitalized patients in Denmark with Enterococcus faecium -positive blood cultures collected between 2010 and 2019 identified in the Danish Microbiology Database. We estimated 30-day hazard ratio (HR) of death or discharge among VRE compared to VSE patients adjusted for age, sex, and comorbidity. The cohort included 6071 patients with E. faecium BSI (335 VRE, 5736 VSE) among whom VRE increased (2010-13, 2.6%; 2014-16, 6.3%; 2017-19; 9.4%). Mortality (HR 1.08, 95%CI 0.90-1.29; 126 VRE, 37.6%; 2223 VSE, 37.0%) or discharge (HR 0.89, 95%CI 0.75-1.06; 126 VRE, 37.6%; 2386 VSE, 41.6%) was not different between VRE and VSE except in 2014 (HR 1.87, 95% CI 1.18-2.96). There was no interaction between time from admission to BSI (1-2, 3-14, and >14 days) and HR of death ( P  = 0.14) or discharge ( P  = 0.45) after VRE compared to VSE, despite longer time for VRE patients (17 vs. 10 days for VSE, P  < 0.0001). In conclusion, VRE BSI was not associated with excess morbidity and mortality. The excess mortality in 2014 only may be attributed to improved diagnostic- and patient-management practices after 2014, reducing time to appropriate antibiotic therapy. The high level of mortality after E. faecium BSI warrants further study.

Background: Elderly nursing home residents are vulnerable to infection from micro-organisms. Hand hygiene is considered one of the most important measures to prevent transmission., Aim: To determine the effect of increased accessibility to alcohol-based hand rub (ABHR) in nursing home wards by monitoring hand hygiene compliance (HHC) among healthcare workers (HCWs)., Methods: An 11-month intervention study was conducted in a Danish six-ward nursing home. Data were collected using an automatic hand hygiene monitoring system (AHHMS). After a baseline period, one extra ABHR dispenser was placed in each of the 150 apartments. Baseline HHC was compared with the HHC during an immediate intervention period and a long-term intervention period., Findings: A total of 159 HCWs were included. The AHHMS registered 341,078 hand hygiene opportunities. Overall baseline HHC was 31% (95% confidence interval: 30-32). A significant +18% absolute immediate effect (first five months) (95% CI: 17-19; P < 0.0001) and +13 percentage points (95% CI: 11-14; P < 0.0001) long-term effect (another four months) were recorded. HCWs working day shifts and short-term employees had a higher baseline HHC than HCWs working evening/night shifts. However, HCWs working night shifts achieved the greatest long-term effect with a mean +27 percentage point difference (P < 0.0001)., Conclusion: Placing an additional ABHR dispenser strategically within staff workflow significantly increased HHC among HCWs, demonstrating a noteworthy effect. The study is the first to report the effect on nursing home dispenser accessibility as a single intervention and to show a significant unmet potential., (Copyright © 2024 The Authors.

Background: Little is known about the challenges faced by women with a neuromuscular disease (NMD) when having to go to the toilet in other places than home; a topic that is highly important for participation and bladder health., Objective: The aim was to investigate whether women with NMD have problems in going to the toilet when not at home, the problems' impact on their social activities, education, and working life, which strategies they use to manage the problems, and the prevalence of lower urinary tract symptoms (LUTS)., Methods: A national survey containing questions on type of NMD, mobility, impacts on social activities, education, working life, and bladder health was developed by women with NMD and researchers. LUTS were assessed by the International Consultation on Incontinence Questionnaire Female Lower Urinary Tract Symptoms Modules (ICIQ-FLUTS). Female patients≥12 years (n = 1617) registered at the Danish National Rehabilitation Centre for Neuromuscular Diseases were invited., Results: 692 women (43%) accepted the invitation; 21% were non-ambulant. 25% of respondents avoided going to the toilet when not at home. One third of respondents experienced that problems in going to the toilet impacted their social life. 43% of respondents refrained from drinking to avoid voiding when not at home, 61% had a low frequency of urinating, 17% had experienced urinary tract infections, and 35% had experienced urine incontinence. Problems were seldom discussed with professionals, only 5% of participants had been referred to neuro-urological evaluation., Conclusion: The results highlight the difficulties in urinating faced by women with NMD when not at home and how these difficulties impact functioning, participation, and bladder health. The study illustrates a lack of awareness of the problems in the neuro-urological clinic. It is necessary to address this in clinical practice to provide supportive treatment and solutions that will enable participation for women with NMD.

Purpose: To describe the occurrence of SARS-CoV-2 infections, deaths and outbreaks among residents in Danish long-term care facilities (LTCFs) from February 2020 to February 2021., Methods: Danish COVID-19 national register data from a newly implemented automated surveillance system was used to describe incidence rate and deaths (per 1000 residents' years), number of tests, SARS-CoV-2 infections and outbreaks among LTCF residents. A case was defined as a LTCF resident with a positive SARS-CoV-2 PCR test. An outbreak was defined as two or more cases in one LTCF within a 14-day period, and considered closed if no new cases had occurred within 28 days. Death was defined as occurring within 30-days of a positive test., Results: A total of 55,359 residents living in 948 LTCFs were included. The median age of the residents was 85 years and 63% were female. There was a total of 3712 cases found among residents across 43% of all LTCFs. Nearly all (94%) cases were linked to outbreaks. Higher numbers of cases and outbreaks were seen in Denmark's Capital Region compared to other regions. Overall, 22 SARS-CoV-2 deaths and 359 deaths (non-SARS-CoV-2) per 1000 resident years were identified in the study period., Conclusion: Less than half of LTCFs identified any cases. The majority of cases were linked to outbreaks, emphasizing the importance of preventing introductions of SARS-CoV-2 into the facilities. Furthermore, it highlights the need to invest efforts into infrastructures, routine procedures and monitoring of SARS-CoV-2 in LTCFs to limit the introduction and the spread of SARS-CoV-2., (© 2023.

From October 2022 through January 2023, nine patients with NDM-5/OXA-48-carbapenemase-producing Enterobacter hormaechei ST79 were detected in Denmark and subsequently one patient in Iceland. There were no nosocomial links between patients, but they had all been treated with dicloxacillin capsules. An NDM-5/OXA-48-carbapenemase-producing E. hormaechei ST79, identical to patient isolates, was cultured from the surface of dicloxacillin capsules in Denmark, strongly implicating them as the source of the outbreak. Special attention is required to detect the outbreak strain in the microbiology laboratory.

Background: Knowledge of the prevalence and socio-demographic characteristics of physical impairments is limited. This study aimed to determine the prevalence of physical impairments among adults in Denmark, both in total and according to nine common diagnostic subgroups, describe the socio-demographic and socio-economic profile, and compare the data with those of the general adult population., Methods: This descriptive, cross-sectional, register-based study evaluated the general socio-demographic and socio-economic variables, including sex, age, geographical region, origin, educational level, occupation, marital status, and disability level, of adults with physical impairments extracted by diagnosis from the Danish National Patient Register and Statistics Denmark by 31 December 2018. These data were compared with those of the general adult population in Denmark extracted from Statistics Denmark by January 2019., Results: In total, 606,857 adults with physical impairments were identified. Of the nine selected diagnoses, osteoarthritis (69.4%) was the most prevalent, followed by acquired brain injury (29.0%), rheumatoid arthritis (6.7%), multiple sclerosis (2.6%), spinal cord injury (1.5%), cerebral palsy (1.2%), amputation (0.7%), muscular dystrophy (0.5%), and poliomyelitis (< 0.1%). There were large variations in the socio-demographic and socio-economic profile between the nine diagnostic subgroups. The adults with physical impairments were more often women, were older, were less often immigrants and employed adults, had a lower educational level, and were more commonly married than the general adult population. Only the geographical region did not differ., Conclusion: The nine subgroups with diagnoses related to the musculoskeletal system represent 13% of the adult Danish population. The socio-demographic and socio-economic profile varied largely between the nine diagnostic subgroups, and almost all variables differed significantly between adults with physical impairments and the general adult population in Denmark. These findings reveal patterns and trends on socio-demographic and socio-economic variables essential for future planning at a societal level, including the healthcare and social sectors., (© 2022.

Denmark hosted four games during the 2020 UEFA European championships (EC2020). After declining positive SARS-CoV-2 test rates in Denmark, a rise occurred during and after the tournament, concomitant with the replacement of the dominant Alpha lineage (B.1.1.7) by the Delta lineage (B.1.617.2), increasing vaccination rates and cessation of several restrictions. A cohort study including 33 227 cases was conducted from 30 May to 25 July 2021, 14 days before and after the EC2020. Included was a nested cohort with event information from big-screen events and matches at the Danish national stadium, Parken (DNSP) in Copenhagen, held from 12 June to 28 June 2021. Information from whole-genome sequencing, contact tracing and Danish registries was collected. Case-case connections were used to establish transmission trees. Cases infected on match days were compared to cases not infected on match days as a reference. The crude incidence rate ratio (IRR) of transmissions was 1.55, corresponding to 584 (1.76%) cases attributable to EC2020 celebrations. The IRR adjusted for covariates was lower (IRR 1.41) but still significant, and also pointed to a reduced number of transmissions from fully vaccinated cases (IRR 0.59). These data support the hypothesis that the EC2020 celebrations contributed to the rise of cases in Denmark in the early summer of 2021.

Study Design: Cross-sectional study., Objectives: To describe the socio-demographics, injury characteristics, prevalence of shoulder and neck symptoms, weekly participation in leisure time physical activity (LTPA) and quality of life (QoL) of individuals with spinal cord injury in Denmark (SCI)., Setting: Nation-wide community survey, Denmark., Methods: Individuals with SCI for >2 years were included from three SCI rehabilitation departments. Questionnaire data regarding socio-demographic details, SCI injury characteristics, medical history, shoulder and neck symptoms, LTPA and QoL were collected., Results: Of 2454 potential participants, 1517 (62%) responded to the survey (mean age = 56.2, SD 16.1, 37% female, 42% tetraplegia, 23% complete SCI, mean time since injury = 16.9, SD 13.5). 75% used some form of assistive mobility device. Responders and non-responders showed no sex or injury type/severity differences. Shoulder and neck symptoms within the past 3 months were reported by 63 and 67% respectively, with 51% reporting shoulder symptoms within the past week. Among those with symptoms, 61% had experienced shoulder symptoms and 56% neck symptoms, for more than 30 days during the previous 3 months. Symptoms often prevented participants from performing their usual activities (due to shoulder symptoms 46%, neck symptoms 41%)., Conclusions: A high prevalence of self-reported shoulder and neck symptoms was found, which may limit physical function and social activities. We succeeded in generating the Danish Spinal Cord Injury Shoulder (DanSCIS) dataset, which comprised a substantial proportion of Danish adults with SCI. Future studies using data from this cohort will investigate patterns and associations between shoulder/neck symptoms, use of assistive mobility devices, LTPA and QoL.

In June-November 2020, SARS-CoV-2-infected mink were detected in 290 of 1,147 Danish mink farms. In North Denmark Region, 30% (324/1,092) of people found connected to mink farms tested SARS-CoV-2-PCR-positive and approximately 27% (95% confidence interval (CI): 25-30) of SARS-CoV-2-strains from humans in the community were mink-associated. Measures proved insufficient to mitigate spread. On 4 November, the government ordered culling of all Danish mink. Farmed mink constitute a potential virus reservoir challenging pandemic control.

BackgroundCarbapenemase-producing Escherichia coli are increasing worldwide. In recent years, an increase in OXA-244-producing E. coli isolates has been seen in the national surveillance of carbapenemase-producing organisms in Denmark.AimMolecular characterisation and epidemiological investigation of OXA-244-producing E. coli isolates from January 2016 to August 2019.MethodsFor the epidemiological investigation, data from the Danish National Patient Registry and the Danish register of civil registration were used together with data from phone interviews with patients. Isolates were characterised by analysing whole genome sequences for resistance genes, MLST and core genome MLST (cgMLST).ResultsIn total, 24 OXA-244-producing E. coli isolates were obtained from 23 patients. Among the 23 patients, 13 reported travelling before detection of the E. coli isolates, with seven having visited countries in Northern Africa. Fifteen isolates also carried an extended-spectrum beta-lactamase gene and one had a plasmid-encoded AmpC gene. The most common detected sequence type (ST) was ST38, followed by ST69, ST167, ST10, ST361 and ST3268. Three clonal clusters were detected by cgMLST, but none of these clusters seemed to reflect nosocomial transmission in Denmark.ConclusionImport of OXA-244 E. coli isolates from travelling abroad seems likely for the majority of cases. Community sources were also possible, as many of the patients had no history of hospitalisation and many of the E. coli isolates belonged to STs that are present in the community. It was not possible to point at a single country or a community source as risk factor for acquiring OXA-244-producing E. coli .

Background: Hand hygiene compliance (HHC) among health care workers remains suboptimal, and good monitoring systems are lacking. We aimed to evaluate HHC using an automated monitoring system., Methods: A prospective, observational study was conducted at 2 Danish university hospitals employing a new monitoring system (Sani nudge). Sensors were located on alcohol-based sanitizers, health care worker name tags, and patient beds measuring hand hygiene opportunities and sanitations., Results: In total, 42 nurses were included with an average HHC of 52% and 36% in hospitals A and B, respectively. HHC was lowest in patient rooms (hospital A: 45%; hospital B: 29%) and highest in staff toilets (hospital A: 72%; hospital B: 91%). Nurses sanitized after patient contact more often than before, and sanitizers located closest to room exits and in hallways were used most frequently. There was no association found between HHC level and the number of beds in patient rooms. The HHC level of each nurse was consistent over time, and showed a positive correlation between the number of sanitations and HHC levels (hospital A: r = 0.69; hospital B: r = 0.58)., Conclusions: The Sani nudge system can be used to monitor HHC at individual and group levels, which increases the understanding of compliance behavior., (Copyright © 2019 Association for Professionals in Infection Control and Epidemiology, Inc.

Background: The benefits of extensive lymph node dissection as performed in complete mesocolic excision are still debated, although recent studies have shown an association with improved long-term outcomes. However, none of these studies had an intention-to-treat design or aimed to show a causal effect; therefore in this study, we aimed to estimate the causal oncological treatment effects of complete mesocolic excision on right-sided colon cancer., Methods: We did a population-based cohort study involving prospective data collected from four hospitals in Denmark. We compared the oncological outcome data of patients at one centre performing central lymph node dissection and vascular division after almost complete exposure of the proximal part of the superior mesenteric vein (ie, the complete mesocolic excision group) with three other centres performing conventional resections with unstandardised and limited lymph node dissection (ie, non-complete mesocolic excision; control group). We included data for all patients in the Capital Region of Denmark undergoing elective curative-intent right-sided colon resections for stages I-III colon cancer, as categorised by the Union for International Cancer Control (UICC; 5th edition), from June 1, 2008, to Dec 31, 2013. Patients were followed-up for 5·2 years after surgery. The primary outcome was the cumulative incidence of recurrence after 5·2 years of surgery. Inverse probability of treatment weighting and competing risk analyses were used to estimate the possible causal effects of complete mesocolic excision. This study is registered with ClinicalTrials.gov, number NCT03754075., Findings: 1069 patients (813 in the control group and 256 in the complete mesocolic excision group) underwent curative-intent elective surgery for right-sided colon cancer during the study period. None of the patients were lost to follow-up regarding survival or recurrence status, and consequently no patient was censored in the analyses. The 5·2-year cumulative incidence of recurrence was 9·7% (95% CI 6·3-13·1) in the complete mesocolic excision group compared with 17·9% (15·3-20·5) in the control group, and the absolute risk reduction of complete mesocolic excision after 5·2 years was 8·2% (95% CI 4·0-12·4; p=0·00015). In the control group, 145 (18%) of 813 patients were diagnosed with a recurrence and 281 (35%) died during follow-up, whereas in the complete mesocolic excision group 25 (10%) of 256 patients were diagnosed with a recurrence and 75 (29%) died during follow-up., Interpretation: This study shows a causal treatment effect of central mesocolic lymph node excision on risk of recurrence after resection for right-sided colon adenocarcinoma. Complete mesocolic excision has the potential to reduce the risk of recurrence and improve long-term outcome after resection for all UICC stages I-III of right-sided colon adenocarcinomas., Funding: The Tvergaard Fund, Helen Rude Fund, Krista and Viggo Petersen Fund, Olga Bryde Nielsen Fund, and Else and Mogens Wedell-Wedellsborg Fund., (Copyright © 2019 Elsevier Ltd.

Aim: Several biomechanical factors, such as knee joint hypermobility (KJH), are suggested to play a role in the etiology of knee joint symptoms and knee osteoarthritis. Nevertheless, the prevalence or consequences of KJH solely or included in the classification of generalized joint hypermobility (GJHk) is unknown for a general population. Therefore, the objectives were to report the prevalence of self-reported GJHk and KJH, as well as the association of these conditions to knee joint symptoms, severity and duration of symptoms, and health-related quality of life (HRQoL) in a Danish adult population., Method: This study is a cross-sectional population-based survey of 2056 Danish adults. Respondents received online questionnaires of GJHk and KJH, knee joint symptoms, the severity and duration of these, as well as HRQoL., Results: Total response rate was 49% (n = 1006). The prevalence of self-reported GJHk and KJH was 13% and 23%, mostly representing women. More than half of the respondents with GJHk and KJH had knee joint symptoms. The odds for reporting knee joint symptoms, severity of knee joint symptoms and duration of knee joint symptoms were twice as high for respondents with GJHk and KJH. Respondents with GJHk and KJH reported lower HRQoL., Conclusion: GJHk and KJH were frequently reported in the Danish adult population, mostly in women. Respondents with GJHk and KJH were two times more likely to report knee joint-related symptoms such as pain, reduced performance of usual activity and lower HRQoL. The impact of these conditions on HRQoL is comparable with knee osteoarthritis., (© 2017 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.)

Background: Rotator cuff tear is a common cause of shoulder disability and results in patients predominantly complaining of pain and loss of motion and strength. Traumatic rotator cuff tears are typically managed surgically followed by ~ 20 weeks of rehabilitation. However, the timing and intensity of the postoperative rehabilitation strategy required to reach an optimal clinical outcome is unknown. Early controlled and gradually increased tendon loading has been suggested to positively influence tendon healing and recovery. The aim of this trial is therefore to examine the effect of a progressive rehabilitation strategy on pain, physical function and quality of life compared to usual care (that limits tendon loading in the early postoperative phase) in patients who have a rotator cuff repair of a traumatic tear., Methods: The current study is a randomized, controlled, outcome-assessor blinded, multicenter, superiority trial with a two-group paralleled design. A total of 100 patients with surgically repaired traumatic rotator cuff tears will be recruited from up to three orthopedic departments in Denmark, and randomized to either a progressive early passive and active movement program or a limited early passive movement program (usual care). The primary outcome measure will be the change from pre-surgery to 12 weeks post-surgery in the Western Ontario Rotator Cuff Index questionnaire. Secondary outcomes include the Disabilities Arm, Shoulder and Hand questionnaire (DASH), range of motion, strength and tendon healing characteristics from ultrasound measurements at 12 months follow up., Discussion: We hypothesized that patients who receive the progressive rehabilitation strategy will benefit more with respect to pain reduction, physical function and quality of life than those who receive care as usual. If this is confirmed our study can be used clinically to enhance the recovery of patients with traumatic rotator cuff tear., Trial Registration: ClinicalTrials.gov, NCT02969135 . Registered on 15 November 2016.

Aim: To investigate whether complete mesocolic excision (CME) might carry a higher risk of bowel dysfunction and subsequent reduction in quality of life compared with conventional resection., Method: A cross-sectional questionnaire study based on data from a national survey regarding long-term bowel function and a population-based cohort study comparing CME (study group) with conventional resection (control group). A total of 622 patients undergoing elective resection for Stage I-III sigmoid adenocarcinoma at four university colorectal centres between June 2008 and December 2014 were eligible to receive the questionnaire in mid-November 2015. Primary outcomes were four or more bowel movements daily, nocturnal bowel movements, unproductive call to stool, obstructive sensation and impact of bowel function on quality of life (QOL)., Results: One hundred and twenty-seven (69.0%) and 289 (66.0%) patients in the study and control groups, respectively, responded to the questionnaire after medians of 4.41 [interquartile range (IQR) 2.50, 5.83] and 4.57 (IQR 3.15, 5.82) years, respectively (P = 0.048). CME was not associated with: increased risk of four or more bowel movements daily [adjusted OR 1.14 (95% CI 0.59-2.14; P = 0.68)], nocturnal bowel movements [adjusted OR 1.31 (0.66-2.53; P = 0.43)], unproductive call to stool [adjusted OR 0.99 (0.54-1.77; P = 0.97)] or obstructive sensation [adjusted OR 1.01 (0.56-1.78; P = 0.96)]. While one in five patients in both groups had moderate to severe impact of bowel function on QOL, there was no association with CME., Conclusion: For patients with sigmoid cancer, CME is associated with neither higher risk of bowel dysfunction nor impaired QOL., (Colorectal Disease © 2018 The Association of Coloproctology of Great Britain and Ireland.)

Aim: Both the Danish and the National Institute of Clinical Excellence (NICE) guidelines recommend prolonged thromboprophylaxis (PT) with low-molecular-weight heparin (LMWH) for 28 days postoperatively after elective surgery for colon cancer. The evidence relies on data from two randomized clinical trials (RCTs) that included not only colon cancers but also other abdominal cancers or benign colorectal diseases. Neither of those studies investigated the risk of venous thromboembolism (VTE) under enhanced recovery after surgery (ERAS). We aim to describe the risk of VTE and estimate the cost of preventing one case of VTE by PT under ERAS., Method: This was a retrospective study of 2230 patients undergoing elective surgery for colon cancer Stage I-III in the Capital Region of Denmark, 1 June 2008 to 31 December 2013. Patients who were discharged on postoperative day 28 or later, died during admission or were discharged with a vitamin K antagonist, novel oral anticoagulants or LMWH were excluded. Patients with rectal cancer only were not included. End-points were symptomatic VTE diagnosed within 60 days postoperatively., Results: Three-hundred and thirty patients were excluded. For the remaining 1893, the median length of stay (LOS) was 4 [interquartile range (IQR): 3-5] days. Of these 1893 patients, four (0.20%) experienced a nonfatal symptomatic VTE. All four patients had other postoperative complications before the VTE. The cost of each symptomatic VTE prevented is estimated to be between £63 709 and £111 455 when medication and home-care nursing are included., Conclusion: The risk of symptomatic VTE after uncomplicated, elective surgery for colon cancer with ERAS seems negligible and the cost-effectiveness of PT to prevent one symptomatic VTE seems questionable., (Colorectal Disease © 2017 The Association of Coloproctology of Great Britain and Ireland.)

The surveillance of Clostridium difficile (CD) in Denmark consists of laboratory based data from Departments of Clinical Microbiology (DCMs) sent to the National Registry of Enteric Pathogens (NREP). We validated a new surveillance system for CD based on the Danish Microbiology Database (MiBa). MiBa automatically collects microbiological test results from all Danish DCMs. We built an algorithm to identify positive test results for CD recorded in MiBa. A CD case was defined as a person with a positive culture for CD or PCR detection of toxin A and/or B and/or binary toxin. We compared CD cases identified through the MiBa-based surveillance with those reported to NREP and locally in five DCMs representing different Danish regions. During 2010-2014, NREP reported 13 896 CD cases, and the MiBa-based surveillance 21 252 CD cases. There was a 99·9% concordance between the local datasets and the MiBa-based surveillance. Surveillance based on MiBa was superior to the current surveillance system, and the findings show that the number of CD cases in Denmark hitherto has been under-reported. There were only minor differences between local data and the MiBa-based surveillance, showing the completeness and validity of CD data in MiBa. This nationwide electronic system can greatly strengthen surveillance and research in various applications.

Objectives: To translate and adapt the Western Ontario Shoulder Instability (WOSI) questionnaire into Danish and, to evaluate measurement properties of an electronic Danish WOSI version., Methods: The Swedish WOSI version was used for translation and adaptation into Danish followed by examination of test-retest reproducibility (14-day interval) besides concurrent and construct validity. Concurrent validity was examined by comparing WOSI in paper version with an electronic version, whereas construct validity was examined by comparing WOSI with Numeric Pain Rating Scale (NPRS) and the Oxford Shoulder Score (OSS). Reproducibility was evaluated with Intraclass correlations (ICC), Standard Error of Measurement (SEM), minimal detectable change (MDC) and limits of agreement (LOA). Validity was evaluated with Pearson's ( r) and Concordance Correlation Coefficients (CCC)., Results: 41 subjects (median age 34, range 18-57) were included in the analysis of reproducibility. An ICC of 0.97 (95% CI 0.95 to 0.99) for the total WOSI score was found. SEM was 100.1, resulting in an MDC of 277.5 and LOAs within the range of -246.4 and 308.6. 25 subjects (median age 34, range 18-72) were included in the analysis of concurrent validity obtaining a CCC of 0.96 (95% CI 0.91 to 0.98). Construct validity was investigated in 62 subjects (median age 31, range 18-72) obtaining correlations of 0.83 (95% CI 0.68 to 0.97) (NPRS) and 0.79 (95% CI 0.62 to 0.94) (OSS)., Conclusions: An electronic Danish version of WOSI presented excellent test-retest reproducibility and acceptable measurement errors. Also, concurrent validity between paper and electronic version was highly satisfactory as was the construct validity. Surprisingly, though, the NPRS correlated more with WOSI than OSS., Competing Interests: Competing interests: None declared., (© Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Background: The Danish Hospital-Acquired Infections Database (HAIBA) is an automated surveillance system using hospital administrative, microbiological, and antibiotic medication data., Aim: To define and evaluate the case definition for hospital-acquired urinary tract infection (HA-UTI) and to describe surveillance data from 2010 to 2014., Methods: The HA-UTI algorithm defined a laboratory-diagnosed UTI as a urine culture positive for no more than two micro-organisms with at least one at ≥10(4)cfu/mL, and a probable UTI as a negative urine culture and a relevant diagnosis code or antibiotic treatment. UTI was considered hospital-acquired if a urine sample was collected ≥48h after admission and <48h post discharge. Incidence of HA-UTI was calculated per 10,000 risk-days. For validation, prevalence was calculated for each day and compared to point prevalence survey (PPS) data., Findings: HAIBA detected a national incidence rate of 42.2 laboratory-diagnosed HA-UTI per 10,000 risk-days with an increasing trend. Compared to PPS the laboratory-diagnosed HA-UTI algorithm had a sensitivity of 50.0% (26/52) and a specificity of 94.2% (1842/1955). There were several reasons for discrepancies between HAIBA and PPS, including laboratory results being unavailable at the time of the survey, the results considered clinically irrelevant by the surveyor due to an indwelling urinary catheter or lack of clinical signs of infection, and UTIs being considered HA-UTI in PPS even though the first sample was taken within 48h of admission., Conclusion: The HAIBA algorithm was found to give valid and valuable information and has, among others, the advantages of covering the whole population and allowing continuous standardized monitoring of HA-UTI., (Copyright © 2016 The Healthcare Infection Society.

Background: Generalised Joint Hypermobility (GJH) is suggested as an aetiological factor for knee injuries in adolescents and adults. It is presumed that GJH causes decreased joint stability, thereby increasing the risk of knee injuries during challenging situations like jumping and landing. The aim was to study the extent and risk of knee injuries in children with GJH and knee hypermobility., Methods: In total, 999 children (9-14 years) were tested twice during spring 2012 and 2013 with Beighton's Tests (BT) for hypermobility, a 0-9 scoring system. GJH was classified with cut-point ≥5/9 on both test rounds. On basis of weekly cell phone surveys of knee pain, children requiring clinical examination were seen. Traumatic and overuse knee injuries were registered by WHO ICD-10 diagnoses. Logistic regression and Poisson regression models with robust standard errors were used to examine the association between GJH and knee injuries, taking into account clustering on school class levels., Results: Totally, 36 children were classified GJH on both test rounds. Overuse knee injuries were the most frequent injury type (86 %), mainly apophysitis for both groups (61 %), other than patella-femoral pain syndrome for the control group (13 %). For traumatic knee injuries, distortions and contusions were most frequent in both groups (51 % resp. 36 %), besides traumatic lesions of knee tendons and muscles for the control group (5 %). No significant association was found between overuse knee injuries and GJH with/without knee hypermobility (OR 0.69, p = 0.407 resp. OR 0.75, p = 0.576) or traumatic knee injuries and GJH with/without knee hypermobility (OR 1.56, p = 0.495 resp. OR 2.22, p = 0.231)., Conclusions: Apophysitis, distortions and contusions were the most frequent knee injuries. Despite the relatively large study, the number of children with GJH and knee injuries was low, with no significant increased risk for knee injuries for this group. This questions whether GJH is a clinically relevant risk factor for knee injuries in school children aged 9-14 years. A fluctuation in the individual child's status of GJH between test rounds was observed, suggesting that inter- and intra-tester reproducibility of BT as well as growth may be considered important confounders to future studies of children with GJH.

Background: Application of the principles of total mesorectal excision to colon cancer by undertaking complete mesocolic excision (CME) has been proposed to improve oncological outcomes. We aimed to investigate whether implementation of CME improved disease-free survival compared with conventional colon resection., Methods: Data for all patients who underwent elective resection for Union for International Cancer Control (UICC) stage I-III colon adenocarcinomas in the Capital Region of Denmark between June 1, 2008, and Dec 31, 2011, were retrieved for this population-based study. The CME group consisted of patients who underwent CME surgery in a centre validated to perform such surgery; the control group consisted of patients undergoing conventional colon resection in three other hospitals. Data were collected from the Danish Colorectal Cancer Group (DCCG) database and medical charts. Patients were excluded if they had stage IV disease, metachronous colorectal cancer, rectal cancer (≤ 15 cm from anal verge) in the absence of synchronous colon adenocarcinoma, tumour of the appendix, or R2 resections. Survival data were collected on Nov 13, 2014, from the DCCG database, which is continuously updated by the National Central Office of Civil Registration., Findings: The CME group consisted of 364 patients and the non-CME group consisted of 1031 patients. For all patients, 4-year disease-free survival was 85.8% (95% CI 81.4-90.1) after CME and 75.9% (72.2-79.7) after non-CME surgery (log-rank p=0.0010). 4-year disease-free survival for patients with UICC stage I disease in the CME group was 100% compared with 89.8% (83.1-96.6) in the non-CME group (log-rank p=0.046). For patients with UICC stage II disease, 4-year disease-free survival was 91.9% (95% CI 87.2-96.6) in the CME group compared with 77.9% (71.6-84.1) in the non-CME group (log-rank p=0.0033), and for patients with UICC stage III disease, it was 73.5% (63.6-83.5) in the CME group compared with 67.5% (61.8-73.2) in the non-CME group (log-rank p=0.13). Multivariable Cox regression showed that CME surgery was a significant, independent predictive factor for higher disease-free survival for all patients (hazard ratio 0.59, 95% CI 0.42-0.83), and also for patients with UICC stage II (0.44, 0.23-0.86) and stage III disease (0.64, 0.42-1.00). After propensity score matching, disease-free survival was significantly higher after CME, irrespective of UICC stage, with 4-year disease-free survival of 85.8% (95% CI 81.4-90.1) after CME and 73.4% (66.2-80.6) after non-CME (log-rank p=0·0014)., Interpretation: Our data indicate that CME surgery is associated with better disease-free survival than is conventional colon cancer resection for patients with stage I-III colon adenocarcinoma. Implementation of CME surgery might improve outcomes for patients with colon cancer., Funding: Tvergaards Fund and Edgar and Hustru Gilberte Schnohrs Fund., (Copyright © 2015 Elsevier Ltd.

Background: Blue-collar workers have a high risk of occupational contact dermatitis, but epidemiological studies are scarce., Objectives: To investigate allergic contact dermatitis in blue-collar workers with dermatitis registered by the Danish Contact Dermatitis Group., Methods: A retrospective analysis of patch test data from 1471 blue-collar workers and 1471 matched controls tested between 2003 and 2012 was performed. A logistic regression was used to test for associations., Results: The blue-collar workers often had occupational hand dermatitis (p < 0.001). Atopic dermatitis was less commonly observed among blue-collar workers (19.6%) than among controls (23.9%) (p = 0.005). Allergens with a statistically significant association with the occupational group of blue-collar workers were epoxy resins, methyldibromo glutaronitrile, 2-bromo-2-nitro-1,3-propanediol, potassium dichromate, and methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI). The following occupations were additionally identified as risk factors for contact sensitization to MCI/MI and MI, epoxy resins, and potassium dichromate, respectively: painting, construction work, and tile setting/terrazzo work., Conclusion: Contact allergy is a major problem among blue-collar workers. The data indicate a healthy worker effect among blue-collar workers diagnosed with dermatitis, as blue-collar workers were diagnosed significantly less often with atopic dermatitis than were controls., (© 2014 John Wiley & Sons A/S.

Background: Occupational contact dermatitis among hairdressers is frequent, owing to daily exposure to irritants and allergens., Objectives: To identify sensitization to the most common allergens associated with the occupation of hairdressing., Methods: Patch test results of 399 hairdressers and 1995 matched controls with contact dermatitis, registered by the Danish Contact Dermatitis Group between January 2002 and December 2011, were analysed. All patients were patch tested with the European baseline series, and hairdressers were additionally tested with the hairdressing series., Results: Occupational contact dermatitis (p < 0.001) and hand eczema (p < 0.001) were observed significantly more often among hairdressers than among controls. Atopic dermatitis was less commonly observed among hairdressers (21.3%) than among controls (29.4%) (p < 0.01). Allergens from the European baseline series with a statistically significant association with the occupation of hairdressing were p-phenylenediamine, thiuram mix, and benzocaine. Frequent sensitizers from the hairdressing series were ammonium persulfate, toluene-2,5-diamine, 3-aminophenol, and 4-aminophenol. Cysteamine hydrochloride and chloroacetamide emerged as new sensitizers., Conclusions: These results indicate a healthy worker effect among hairdressers diagnosed with eczema. Ammonium persulfate and p-phenylenediamine remain frequent sensitizers in hairdressers with contact dermatitis. Cysteamine hydrochloride and chloroacetamide should be included in future surveillance studies., (© 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.)

Background: Painters are among the occupational groups that most commonly experience occupational contact dermatitis, but few investigations exist concerning this occupation., Objectives: To characterize painters with contact dermatitis and identify the most common allergens associated with the occupation. Materials and methods. All patch test results of 219 painters and 1095 matched controls registered by the Danish Contact Dermatitis Group between 2001 and 2010 were analysed., Results: Hand eczema (p < 0.0001) and occupational contact dermatitis (p < 0.0001) were observed significantly more often in the painters than in the group of controls. Sensitizations to the following allergens from the European baseline series were associated with the occupation and were statistically significant: methylchloroisothiazolinone/methylisothiazolinone, epoxy resin, formaldehyde, and quaternium-15. Three different isothiazolinones emerged as the most frequent sensitizers of the allergens tested in addition to the baseline series., Conclusions: The results indicate that painters have an increased risk of developing occupational hand eczema. Isothiazolinones and epoxy resin proved to be the two most frequent sensitizers in painters., (© 2012 John Wiley & Sons A/S.)

With the emergence of reduced susceptibility of Clostridium difficile to metronidazole and vancomycin the value of antimicrobial susceptibility testing has increased. The aim of our study was to evaluate disk diffusion for susceptibility testing of C. difficile by comparing disk diffusion results with MICs from gradient tests and to propose zone diameter breakpoint correlates for the EUCAST epidemiological cut-off values (ECOFFs) recently published. We tested 211 clinical isolates of C. difficile, from patients with diarrhoea hospitalized at Aarhus and Odense University Hospitals, Denmark. Furthermore, ten clinical isolates of C. difficile from the Anaerobe Reference Laboratory, University Hospital of Wales, with known reduced susceptibility to either metronidazole or vancomycin, were included. Isolates were tested with Etest gradient strips and disk diffusion towards metronidazole, vancomycin and moxifloxacin on Brucella Blood Agar supplemented with hemin and vitamin K. We found an excellent agreement between inhibition zone diameter and MICs. For each MIC value, the inhibition zones varied from 0 to 8 mm, with 93% of values within 6 mm for metronidazole, 95% of values within 4 mm for vancomycin, and 98% of values within 4 mm for moxifloxacin. With proposed zone diameter breakpoints for metronidazole, vancomycin and moxifloxacin of WT ≥ 23 mm, WT ≥ 19 and WT ≥ 20 mm, respectively, we found no very major errors and only major errors below 2%. In conclusion, we suggest that disk diffusion is an option for antimicrobial susceptibility testing of C. difficile., (© 2012 The Authors.

Background: Information is sparse regarding the association between international travel and hospitalization with non-typhoidal Salmonella bacteremia. The aim of this study was to determine the proportion, risk factors and outcomes of travel-related non-typhoidal Salmonella bacteremia., Methods: We conducted a 10-year population-based cohort study of all patients hospitalized with non-typhoidal Salmonella bacteremia in three Danish counties (population 1.6 million). We used denominator data on Danish travellers to assess the risk per 100,000 travellers according to age and travel destination. We used patients contemporaneously diagnosed with travel-related Salmonella gastroenteritis as reference patients to estimate the relative risk of presenting with travel-related bacteremia as compared with gastroenteritis. To evaluate clinical outcomes, we compared patients with travel-related bacteremia and patients with domestically acquired bacteremia in terms of length of hospital stay, number of extraintestinal focal infections and mortality after 30 and 90 days., Results: We identified 311 patients hospitalized with non-typhoidal Salmonella bacteremia of whom 76 (24.4%) had a history of international travel. The risk of travel-related bacteremia per traveller was highest in the age groups 15-24 years (0.8/100,000 travellers) and 65 years and above (1.2/100,000 travellers). The sex- and age-adjusted relative risk of presenting with bacteremia was associated with travel to Sub-Saharan Africa (odds ratio 18.4; 95% confidence interval [6.9-49.5]), the Middle East (10.6; [2.1-53.2]) and South East Asia (4.0; [2.2-7.5]). We found high-risk countries in the same three regions when estimating the risk per traveller according to travel destination. Patients hospitalized with travel-related bacteremia had better clinical outcomes than patients with domestically acquired bacteremia, they had a shorter length of hospital stay (8 vs. 11 days), less extraintestinal focal infections (5 vs. 31 patients) and a lower risk of death within both 30 days (relative risk 0.2; [0.1-0.7]) and 90 days (0.3; [0.1-0.7]). A healthy traveller effect was a plausible explanation for the observed differences in outcomes., Conclusions: International travel is a notable risk factor for being hospitalized with non-typhoidal Salmonella bacteremia and the risk differs between age groups and travel destinations. Healthy travellers hospitalized with bacteremia are less likely to have poor outcomes than patients with domestically acquired bacteremia.

The aims were to test the intraexaminer reproducibility and report the presence of specific clinical variables of scapular dyskinesis in cases with trapezius myalgia and healthy controls, along with general health and work ability. A total of 38 cases and 23 controls were tested for scapular dyskinesis, general health, and work ability, and 19 cases and 14 controls participated in the reproducibility study. Intraexaminer reproducibility was good to excellent for 6 of 10 clinical variables (Intraclass Correlation Coefficient [ICC] 0.76-0.91; kappa 0.84-1.00), and fair to good for four variables (ICC 0.42-0.74), test for muscular weakness having the lowest ICC (0.42). Cases showed significantly larger medial border misalignment, larger lower horizontal distance of the inferior scapular angle and larger passive shoulder internal rotation, by 110% (1.02 cm), 15% (1.38 cm), and 8% (5.5°), respectively. Cases with the highest degree of scapular dyskinesis showed reduced work ability and general health. The present specific clinical variables on scapular dyskinesis showed satisfactory intraexaminer reproducibility. An increased standardization must be implemented to increase reproducibility of tests for muscular weakness, and the interexaminer reproducibility must be tested for all variables. Finally, scapular dyskinesis in cases with trapezius myalgia must be followed longitudinally for clinical importance.

Background: No generally accepted classification scheme for hand eczema exists. The Danish Contact Dermatitis Group recently developed a guideline defining common clinical types and providing criteria for aetiological types., Objectives: To test the concepts of this guideline in a group of hand eczema patients., Methods: Seven hundred and ten hand eczema patients were included from seven dermatology clinics in Denmark. The hand eczema was classified into one of five clinical types, with standard photographs as reference. The severity was scored by the physician, who also made a final aetiological diagnosis., Results: Irritant contact dermatitis was most frequent in chronic, dry fissured hand eczema (44.3%), pulpitis (41.7%), and nummular hand eczema (40.9%), whereas allergic contact dermatitis dominated in vesicular types of hand eczema, with recurrent (35%) and few (24.2%) eruptions. Hyperkeratotic palmar hand eczema was the only clinical type that constituted a distinct subgroup; it was found most frequently in older men and had the strongest relationship, although not significant, with non-specific dermatitis., Conclusions: The relationship between clinical type of hand eczema and aetiological diagnosis fitted with general experience, but no simple relationship was found. This emphasizes that patch testing and exposure analysis are mandatory. Hyperkeratotic palmar hand eczema was identified as a distinct clinical subtype., (© 2011 John Wiley & Sons A/S.)

Background: Many studies show a relation between reduced lumbar motor control (LMC) and low back pain (LBP). However, test circumstances vary and during test performance, subjects may change position. In other words, the reliability--i.e. reproducibility and validity--of tests for LMC should be based on quantitative data. This has not been considered before. The aim was to analyse the reproducibility of five different quantitative tests for LMC commonly used in daily clinical practice., Methods: The five tests for LMC were: repositioning (RPS), sitting forward lean (SFL), sitting knee extension (SKE), and bent knee fall out (BKFO), all measured in cm, and leg lowering (LL), measured in mm Hg. A total of 40 subjects (14 males, 26 females) 25 with and 15 without LBP, with a mean age of 46.5 years (SD 14.8), were examined independently and in random order by two examiners on the same day. LBP subjects were recruited from three physiotherapy clinics with a connection to the clinic's gym or back-school. Non-LBP subjects were recruited from the clinic's staff acquaintances, and from patients without LBP., Results: The means and standard deviations for each of the tests were 0.36 (0.27) cm for RPS, 1.01 (0.62) cm for SFL, 0.40 (0.29) cm for SKE, 1.07 (0.52) cm for BKFO, and 32.9 (7.1) mm Hg for LL. All five tests for LMC had reproducibility with the following ICCs: 0.90 for RPS, 0.96 for SFL, 0.96 for SKE, 0.94 for BKFO, and 0.98 for LL. Bland and Altman plots showed that most of the differences between examiners A and B were less than 0.20 cm., Conclusion: These five tests for LMC displayed excellent reproducibility. However, the diagnostic accuracy of these tests needs to be addressed in larger cohorts of subjects, establishing values for the normal population. Also cut-points between subjects with and without LBP must be determined, taking into account age, level of activity, degree of impairment and participation in sports. Whether reproducibility of these tests is as good in daily clinical practice when used by untrained examiners also needs to be examined.

Background: Fragrances frequently cause contact allergy, and cosmetic products are the main causes of fragrance contact allergy. As the various products have distinctive forms of application and composition of ingredients, some product groups are potentially more likely to play a part in allergic reactions than others., Aim: To determine which cosmetic product groups cause fragrance allergy among Danish eczema patients., Method: This was a retrospective study based on data collected by members of the Danish Contact Dermatitis Group. Participants (N = 17,716) were consecutively patch tested with fragrance markers from the European baseline series (2005-2009)., Results: Of the participants, 10.1% had fragrance allergy, of which 42.1% was caused by a cosmetic product: deodorants accounted for 25%, and scented lotions 24.4%. A sex difference was apparent, as deodorants were significantly more likely to be listed as the cause of fragrance allergy in men (odds ratio 2.2) than in women. Correlation was observed between deodorants listed as the cause of allergy and allergy detected with fragrance mix II (FM II) and hydroxyisohexyl 3-cyclohexene carboxaldehyde., Conclusion: Deodorants were the leading causes of fragrance allergy, especially among men. Seemingly, deodorants have an 'unhealthy' composition of the fragrance chemicals present in FM II., (© 2011 John Wiley & Sons A/S.)

Introduction: Treatment of hip fractures has evolved since the introduction of fast-track surgical programs in the late 1990s. The aim of our study was to describe the quality of treatment and care related to fast-track hip fracture surgery in Denmark by external audit of patient records., Material and Methods: This was a national multicenter audit of hospital charts from each hospital treating ≥ 50 hip fracture patients per year (n = 594)., Results: The study demonstrated significant variability in treatment and care of patients with hip fractures among the regions of Denmark. Pain management, nutritional screening, ambulation characteristics, training in activities of daily living, and rehabilitation planning were consistently inadequate. Length of stay was 7-11 days., Conclusion: Although the principles for fast-track surgery have been adapted to some extent at all departments in Denmark with an annual treatment of at least 50 patients with hip fractures, no single department has implemented the whole package. Hospital stay has been reduced since the introduction of fast-track regimes, and improvements were seen in many of the quality indicators. Implications for future practice include better adherence to clinical guidelines, a more homogeneous documentation system in nursing, promotion of evidence-based standards, and improved treatment and care of the physical and psychological consequences of hospitalization.

Background: Fragrance mix II (FM II) is a relatively new screening marker for fragrance contact allergy. It was introduced in the patch test baseline series in Denmark in 2005 and contains six different fragrance chemicals commonly present in cosmetic products and which are known allergens., Aim: To investigate the diagnostic contribution of including FM II in the baseline series by comparing it with other screening markers of fragrance allergy: fragrance mix I (FM I), Myroxylon pereirae and hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC)., Method: Retrospective study of 12 302 patients consecutively patch tested with FM II by members of the Danish Contact Dermatitis Group 2005-2008., Results: FM II gave a positive patch test in 553 patients (4.5%), and in 72.2% of these patients the reaction was judged to be clinically relevant. FM II ranked second in detecting fragrance allergy, after FM I. If FM II had not been included as a screening marker in the baseline series, 15.6% (n = 202) of individuals with fragrance allergy would not have been identified by the other fragrance screening markers (FM I, M. pereirae or HICC)., Conclusion: FM II contributes substantially to detecting fragrance allergy. It ranked second among the fragrance screening markers tested in the baseline series and detects individuals with an allergy who otherwise would not have been identified., (© 2010 John Wiley & Sons A/S.)

Invasive disease as a result of Campylobacter is rarely reported. We reviewed 46 cases of blood stream infection with Campylobacter in a Danish population with complete follow-up. The incidence was 2.9 per 1 million person-years with a peak incidence in the age group above 80 years. In the population, the ratio of notified bacteraemia/enteritis patients with Campylobacter infection was 0.004. Patients with bacteraemia were older and had higher comorbidity, e.g. alcoholism, immunosuppression, previous gastrointestinal surgery or HIV infection. We found 26% of blood isolates resistant to ciprofloxacin. The length of hospitalization was significantly longer in bacteraemia patients, whereas the outcome was favourable with 28-day mortality of 4% in bacteraemia patients and 1% in enteritis patients. None of the bacteraemia patients relapsed within 365-day follow-up.

Background: Parasitic helminth infections can protect against allergic airway inflammation in experimental models and have been associated with a reduced risk of atopy and a reduced course of asthma in some observational studies. Although no clinical evidence exists to support the use of helminth therapy for allergic disease, the helminth Trichuris suis has demonstrated efficacy in treatment of inflammatory bowel disease., Objective: To determine efficacy of helminth therapy for allergic rhinitis., Methods: We conducted a double-blind, placebo-controlled, parallel group trial in which 100 subjects age 18 to 65 years with grass pollen-induced allergic rhinitis were randomly assigned to ingest a total of 8 doses with 2500 live T suis ova or placebo with an interval of 21 days. The primary outcome was a change in mean daily total symptom score for runny, itchy, sneezing nose (maximum change, 9.0) or in percentage of well days during the grass pollen season., Results: Treatment with T suis ova (N = 49) compared with placebo (N = 47) caused transient diarrhea peaking at day 41 in 33% of participants (placebo, 2%), and increased eosinophil counts (P < .001) and T suis-specific IgE (P < .05), IgG (P < .001), IgG(4) (P < .003), and IgA (P < .001), whereas there was no significant change in symptom scores (0.0; 95% CI, -0.5 to 0.4; P = .87), well days (3%; 95% CI, -9% to 14%; P = .63), total histamine (P = .44), grass-specific IgE (P = .76), or diameter of wheal reaction on skin prick testing with grass (P = .85) or 9 other allergens., Conclusion: Repeated treatment with the helminth T suis induced a substantial clinical and immunologic response as evidence of infection, but had no therapeutic effect on allergic rhinitis., (Copyright 2010 American Academy of Allergy, Asthma & Immunology.

We investigated the association between the amount of alcohol-based hand rub (hereafter, "hand rub") used and the incidence of healthcare-acquired bloodstream infection (HCR-BSI) from 2004 through early 2008. The amount of hand rub used increased significantly, and the incidence of HCR-BSI remained stable. There was no significant association between the amount of hand rub used and the incidence of HCR-BSI.

Background: Since 2004, we have promoted alcohol-based hand rubbing (HR) with an e-learning program (ELP) among hospital staff. This study sought to determine whether an ELP improves adherence to correct HR., Methods: This was a cohort study of staff members at Aarhus University Hospital, Skejby, Denmark who completed the ELP and were repeatedly observed for correct HR before and after clinical procedures in 2006 and/or 2007., Results: Of the 496 participants, 13% completed the ELP in both 2006 and 2007, 29% completed the ELP only in 2006, 15% completed the ELP only in 2007, and 43% never completed the ELP. Compared with noncompleters, completers of the 2006 and 2007 ELP had a significantly higher adherence to correct HR both before clinical procedures (odds ratio [OR] = 1.54; 95% confidence interval [CI] = 1.11 to 2.13) and after clinical procedures (OR = 1.40; 95% CI = 1.03 to 1.89). Time since completing the ELP seemed to be inversely associated with adherence to correct HR., Conclusion: Completion of an ELP may have a positive impact on the performance of correct HR. The demands of lifelong education and training of hospital staff may call for the use of an ELP as a supplement to existing efforts aimed at improving HR to help prevent health care-related infections.

Background & Aims: Various commensal enteric and potentially pathogenic bacteria may be involved in the pathogenesis of inflammatory bowel diseases (IBD). We compared the risk of IBD between a cohort of patients with documented Salmonella or Campylobacter gastroenteritis and an age- and gender-matched control group from the same population in Denmark., Methods: We identified 13,324 patients with Salmonella/Campylobacter gastroenteritis from laboratory registries in North Jutland and Aarhus counties, Denmark, from 1991 through 2003, and 26,648 unexposed controls from the same counties. Of these, 176 exposed patients with IBD before the infection, their 352 unexposed controls, and 80 unexposed individuals with IBD before the Salmonella/Campylobacter infection were excluded. The final study cohort of 13,148 exposed and 26,216 unexposed individuals were followed for up to 15 years (mean, 7.5 years)., Results: A first-time diagnosis of IBD was reported in 107 exposed (1.2%) and 73 unexposed individuals (0.5%). By age, gender, and comorbidity adjusted Cox proportional hazards regression analysis, the hazard ratio (95% confidence interval) for IBD was 2.9 (2.2-3.9) for the whole period and 1.9 (1.4-2.6) if the first year after the Salmonella/Campylobacter infection was excluded. The increased risk in exposed subjects was observed throughout the 15-year observation period. The increased risk was similar for Salmonella (n = 6463) and Campylobacter (n = 6685) and for a first-time diagnosis of Crohn's disease (n = 47) and ulcerative colitis (n = 133)., Conclusions: In our population-based cohort study with complete follow-up, an increased risk of IBD was demonstrated in individuals notified in laboratory registries with an episode of Salmonella/Campylobacter gastroenteritis.

We hypothesised that haematological malignancies increase the risk of acquiring zoonotic Salmonella or Campylobacter gastroenteritis. The population-based study comprised all first-time Salmonella/Campylobacter gastroenteritis cases in two Danish counties (1991-2003), with age- and gender-matched controls from the background population. We linked the study cohort to registries to obtain data on malignancies, chemotherapy (yes/no), and main comorbidities diagnosed before Salmonella/Campylobacter gastroenteritis. Based on this design, we determined incidence rate ratios (IRR) in conditional logistic regression analyses, and we used weighted mean regression curves to evaluate fluctuations in risk 0-5 years after the malignancy diagnosis. Sixty-eight of 13,324 cases (0.5%) and 29 of 26,648 controls (0.1%) had haematological malignancy before their Salmonella/Campylobacter gastroenteritis. Comorbidity-adjusted IRR for Salmonella/Campylobacter gastroenteritis in patients with haematological malignancy as compared to patients without malignancy were 4.46 [95% confidence intervals (CI), 2.88-6.90] for all individuals, 8.33 (95% CI, 4.31-16.1) for Salmonella, and 2.17 (95% CI, 1.15-4.08) for Campylobacter. Stratification on chemotherapy treatment did not change these estimates. In time-related analyses, IRR were 7-8 in the first 2 years after the haematological malignancy diagnosis and 4-5 in the following 3 years. Patients with haematological malignancy had increased long-term risk of enquiring Salmonella or Campylobacter gastroenteritis.
