Objective: To explore whether an occupational therapy intervention combined with physiotherapy rehabilitation improved hip fracture patient outcomes regarding emotional distress, fatigue, independence and function. Design: Randomized controlled trial. Setting: Inpatient trauma ward in a rehabilitation and trauma hospital. Participants: One hundred and twenty-two patients admitted into hospital for hip fracture. Intervention: Patients were randomly assigned to a standard care group (SC, n = 61) or a combined treatment group (CT, n = 61). The SC group received conventional hospital care for hip fracture patients and the CT group underwent occupational therapy as well. Main measures: Patients’ emotional distress (GHQ-28), perceived fatigue (the first item of the BASDAI using a 0–100 visual analogue scale scale), level of independence (Modified Barthel Index) and function (Harris Hip Score) were measured at baseline and one, three and six months after the intervention. Results: Patients in the CT group experienced a considerable decrease of emotional distress at three and six months ( p = 0.005 and p < 0.001, respectively). A between-group analysis showed significant differences in emotional distress at one, three and six months ( p < 0.001). Although fatigue levels decreased in the SC group, the most significant decline was reported by the CT group at six months ( p < 0.001, mean difference = 14 points). Regarding independence level, significant differences were found within groups at each stage, but also between groups at one month in favor of the CT group. Function improved in both groups compared with baseline ( p < 0.001), but no significant differences were found in functionality between groups. Conclusion: Although both groups reported significant improvements, patients in the CT group had better scores in emotional distress and dependence throughout follow-up and better scores in all measures at six months.

Background Computed tomography (CT) is the gold standard for evaluation of pulmonary nodules and is at the same time responsible for the majority of the collective effective dose. Purpose To evaluate radiation dose and efficacy of computer-assisted detection (CAD) for solid pulmonary nodules in low dose chest CT performed at 70 kV. Material and Methods CAD was performed upon chest CT with 70 kV and 100 kV (gold standard) at manufacture’s recommended tube current of 87 mAs (collimation, 64 × 0.6 mm). Detection rate for pulmonary nodules and size measurements of both techniques were compared to each other. Radiation dosage in terms of effective dose (E) was measured using an Alderson-Rando Phantom. Results Seventy-four patients with 301 solid nodules were included in the study. CAD detection rate was similar for 70 kV (94.7%) and 100 kV (92.4%). Mean transversal nodule diameter was 5.5 mm for 70 kV and 5.7 mm for 100 kV with an average volume of 0.12 mL (both techniques). Derived from the phantom measurements patient examinations resulted in an E of 0.51 mSv (70 kV) versus 2.02 mSv (100 kV). Conclusion 70 kV low-dose chest CT is suitable for CAD based lung nodule analysis at a fraction of the radiation burden of the standard technique. Since the measurements are highly accurate, 70 kV CT could be used for detection of pulmonal lesions as well as follow-up studies.

Published: November 2013

Background Sporadic hemiplegic migraine (SHM) is defined as migraine attacks associated with some degree of motor weakness during the aura phase and where no first-degree relative has identical attacks. SHM has a wide inter- and intraindividual clinical spectrum and, in case of prolonged aura symptoms and disturbed consciousness, can mimic several other acute neurological diseases. Case In 1996, during his wedding night, a 28-year-old man developed left face, arm and leg weakness, nausea and a throbbing headache. Neurological examination on presentation revealed stupor, fever, meningism and left hemiplegia. There were no abnormalities on emergency magnetic resonance. Lumbar puncture showed mild lymphocytic pleocytosis and slightly elevated protein. He received symptomatic treatment. Subsequent genetic analysis revealed the T666M mutation in the CACNA1A gene of chromosome 19. He was diagnosed with SHM. In 2005, at the end of another episode of hemiplegic migraine (HM), he for the first time developed an episode of paranoid psychosis with anxiety and visual hallucinations. The psychiatric symptoms resolved within a week. Discussion All perfusion SPECT and transcranial Doppler studies performed in the first days of HM attacks were consistent with hyperemia of the hemisphere contralateral to the neurological signs. FDG-PET/CT in January 2013 revealed a diffusely reduced glucose metabolism of the supratentorial cortex and marked asymmetric hypometabolism of the left cerebellum. The finding of progressive cortical metabolic dysfunction over years appears as a new finding. Glucose hypometabolism may indicate primary neuronal dysfunction as the cause of the prolonged deficits.

Published: November 2013

Background: There has been no study about treatment guidelines for arthroscopic repair according to the size of bony Bankart lesions of less than 25% of the glenoid width. Purpose: To evaluate the results of arthroscopic repair for bony Bankart lesions managed with different repair techniques based on their size. Study Design: Case series; Level of evidence, 4. Methods: Between March 2005 and February 2009, 44 of 52 consecutive patients with bony Bankart lesions with a size of less than 25% of the entire glenoid were managed with an arthroscopic approach. Of those patients, 34 (77%) were available for outcome analysis at a minimum 24 months’ follow-up (mean, 34 months; range, 24-60 months). The size of the fragment was measured by computed tomography (CT) and classified as small (<12.5% of the inferior glenoid width) and medium (12.5%-25%). Sixteen lesions were classified as small (small group), and 18 were classified as medium (medium group). For small lesions, capsulolabral repair using suture anchors without excision of the bony fragment was performed. For medium lesions, anatomic reduction and fixation using suture anchors was performed, and the adequacy of reduction was assessed by CT postoperatively. The visual analog scale (VAS) for pain score and modified Rowe score for bony Bankart repair were compared and the postoperative recurrence rate investigated. Results: One patient from the small group (6.3%) and 1 patient without anatomic reduction of the bony fragment in the medium group (5.6%) experienced traumatic redislocations. The mean VAS score improved from 1.7 preoperatively to 0.5 at final follow-up, and the mean Rowe score improved from 59 to 91 (both P < .001). The mean postoperative Rowe scores increased from 58 to 92 in the small group and from 60 to 91 in the medium group (both P < .001). Residual joint incongruity measuring ≤2 mm on both axial and coronal scans, which was considered an anatomic reduction, was present in 14 cases (77.8%) in the medium group. In the medium group, the mean postoperative Rowe scores increased from 60 to 95 in cases of anatomic reduction compared with an increase from 56 to 76 in cases of nonanatomic reduction. The Rowe score was statistically correlated with anatomic reduction of medium-sized bony fragments ( P = .046). Conclusion: In small Bankart lesions, restoration of capsulolabral soft tissue tension alone may be enough, whereas in medium lesions, the osseous architecture of the glenoid should be reconstructed for more functional improvement and less pain.

Background: Osteochondritis dissecans (OCD) is a disorder of subchondral bone and articular cartilage whose incidence in children is not clearly known. Purpose: The purpose of this study was to assess the demographics and epidemiology of OCD of the knee in children. Study Design: Descriptive epidemiology study. Methods: A retrospective chart review of an integrated health system was performed on patients with OCD of the knee aged 2 to 19 years from 2007 to 2011, with over 1 million patients in this cohort. Lesion location, laterality, and all patient demographics were recorded. The incidence of OCD was determined for the group as a whole and by sex and age group (2-5 years, 6-11 years, and 12-19 years). Patient differences based on age, sex, and ethnicity were analyzed, and using multivariable logistic regression models, associations between age, sex, ethnicity, and diagnosis of OCD of the knee were evaluated. Results: One hundred ninety-two patients with 206 OCD lesions of the knee fit the inclusion criteria. No OCD lesion of the knee was found in 2- to 5-year-old children. One hundred thirty-one (63.6%) lesions were in the medial femoral condyle, 67 (32.5%) were in the lateral femoral condyle, 96 (50.0%) lesions were right sided, 82 (42.7%) were left sided, and 14 (7.3%) were bilateral. The incidence of patients with OCD of the knee aged 6 to 19 years was 9.5 per 100,000 overall and 15.4 and 3.3 per 100,000 for male and female patients, respectively. Those aged 12 to 19 years represented the vast majority of OCD, with an incidence of 11.2 per 100,000 versus 6.8 per 100,000 for those aged 6 to 11 years. For those aged 6 to 11 and 12 to 19 years, female patients had an incidence of 2.3 and 3.9 per 100,000, respectively, while male patients had an incidence of 11.1 and 18.1 per 100,000, respectively. Multivariable logistic regression analysis revealed a 3.3-fold increased risk of OCD of the knee in patients aged 12 to 19 years compared with those aged 6 to 11 years ( P < .001; 95% confidence interval [CI], 2.37-4.48), and male patients had 3.8 times a greater risk of OCD of the knee than female patients ( P < .001; 95% CI, 2.71-5.41). Based on race and ethnicity, blacks had the highest odds ratio of OCD of the knee compared with all other ethnic groups. Conclusion: In this population-based cohort study of pediatric OCD of the knee, male patients had a much greater incidence of OCD and almost 4 times the risk of OCD compared with female patients. Also, patients aged 12 to 19 years had 3 times the risk of OCD of the knee as compared with 6- to 11-year-old children.

Published: November 2013

Background: Chronic exertional compartment syndrome can present either as anterolateral lower leg pain or as painful muscle herniation. If an athlete or a soldier wants to continue training, there is no proven effective nonoperative treatment, and fasciotomy of 1 or more of the lower leg muscle compartments is usually recommended. Our clinical protocol differs from most reported ones in the use of the forefoot rise test to increase pressure and provoke pain and our recommending minimal surgery of the anterior compartment only. We present results of surgery based on our clinical management flowchart. Methods: Patients who had surgery during a 12-year period were reviewed by telephone interview or office examination. Pain was graded from 0 (none) to 4 (unbearable). Preoperative resting and exercise anterior compartment pressures were evaluated in most subjects before and immediately following a repeated weight-bearing forefoot rise test. Surgery was under local anesthesia, limited to the anterior compartment only and percutaneous (excepting muscle hernias). There were 36 patients, mean age 24 years. Results: Of 16 patients who were originally operated unilaterally, 5 patients were later operated on the other side. Mean presurgery resting pressure was 56 mm Hg (40-80 mm Hg) rising to 87 mm Hg (55-150 mm Hg) with exercise. Mean exercise pain score dropped from 2.9 presurgery to 1.3 postsurgery (n = 35, P < .0001). Complications included superficial peroneal nerve injury (3 legs in 3 patients, 1 requiring reoperation). Conclusion: When we used our clinical management flowchart based on the forefoot rise test, percutaneous fasciotomy of the anterior compartment alone provided good clinical results. Care must be taken to prevent injury to the superficial peroneal nerve in the distal lower leg. Level of Evidence: Level IV, retrospective case series.

Published: November 2013

Purpose: To evaluate the long-term results of endovascular and hybrid treatment in patients with Trans-Atlantic Inter-Society Consensus (TASC) II type “C” and “D” aortoiliac lesions and to highlight, in contrast to TASC II guidelines, the importance to analyze individually the lesions of a single iliac axis. Methods: From January 2008 to December 2012, 50 patients with TASC II type C and D aortoiliac lesions underwent endovascular or hybrid treatment. In 38 patients (76%), the lesions were treated by endovascular approach, while in 12 (24%) patients surgical treatment was adopted. All patients underwent a postoperative surveillance program at 1, 3, and 6 months for the first year and every 6 months thereafter. Results: Technical success was achieved in all patients (100%). The postoperative complication rate was 4%. Primary patency rate was 93.3% at 1 year, 90.2% at 2 years, and 86.6% at 3 years. Cumulative secondary patency rate was 97.7% at 1, 2, and 3 years. Survival after 1 and 2 years was 94.8% and after 3 years was 91.1%. Limb salvage was 100% for the entire period of follow-up. Conclusions: In contrast to TASC II guidelines, the endovascular or hybrid treatment should be considered a valid approach for type C and D lesions. The hybrid treatment, in selected cases, is an effective method to improve the runoff, which plays a key role in the success of the treatment of multilevel stenoocclusive lesions. In TASC II C to D iliac lesions, a specific overview of each axis is necessary in order to select the most appropriate treatment.
Role of ultrasound in the understanding and management of vasculitis
Authors: Schmidt Wolfgang A. 
Published: November 2013

Vasculitis is characterized by a circumferential vessel-wall thickening (‘halo’), which can be visualized by modern imaging techniques. In particular, the resolution of ultrasound has increased to 0.1 mm. Ultrasound detects abnormalities that are pathognomonic even in arteries with a diameter below 1 mm. It is particularly helpful in the diagnosis of large-vessel vasculitides, such as classic temporal arteritis, large-vessel giant-cell arteritis (GCA), Takayasu arteritis and idiopathic aortitis. Echocardiography is important for determining cardiac involvement in Takayasu arteritis and also for examining the coronary arteries of children with suspected Kawasaki disease, which is a medium-vessel vasculitis. In small vessel vasculitides ultrasound has only a role for determining the distribution or organ involvement. Fast-track clinics for the diagnosis of GCA help to initiate treatment before complications such as blindness occur; patients receive appointments within 24 h in these clinics. Clinical examination and ultrasound of temporal and axillary arteries are performed by an experienced rheumatologist. In most cases this is able to determine if GCA is present. Temporal artery biopsy can be still carried out in ambivalent cases. The wall swelling of temporal arteries disappears after 2–3 weeks of glucocorticoid treatment. After 3 days of treatment, diagnosis becomes more difficult with ultrasound in some cases. In larger arteries, such as the axillary arteries, wall thickening disappears within months. It tends to be darker (more hypoechoic) in acute disease because of oedema.

Abstract

Background
Hybridization is a useful strategy to alter the genotypes and phenotypes of the offspring. It could transfer the genome of one species to another through combing the different genome of parents in the hybrid offspring. And the offspring may exhibit advantages in growth rate, disease resistance, survival rate and appearance, which resulting from the combination of the beneficial traits from both parents.

Results
Diploid and triploid hybrids of female grass carp (Ctenopharyngodon idellus, GC, Cyprininae, 2n = 48) × male blunt snout bream (Megalobrama amblycephala, BSB, Cultrinae, 2n = 48) were successfully obtained by distant hybridization. Diploid hybrids had 48 chromosomes, with one set from GC and one set from BSB. Triploid hybrids possessed 72 chromosomes, with two sets from GC and one set from BSB.
The morphological traits, growth rates, and feeding ecology of the parents and hybrid offspring were compared and analyzed. The two kinds of hybrid offspring exhibited significantly phenotypic divergence from GC and BSB. 2nGB hybrids showed similar growth rate compared to that of GC, and 3nGB hybrids significantly higher results. Furthermore, the feeding ecology of hybrid progeny was omnivorous.
The 5S rDNA of GC, BSB and their hybrid offspring were also cloned and sequenced. There was only one type of 5S rDNA (designated type I: 180 bp) in GC and one type of 5S rDNA (designated type II: 188 bp) in BSB. However, in the hybrid progeny, diploid and triploid hybrids both inherited type I and type II from their parents, respectively. In addition, a chimera of type I and type II was observed in the genome of diploid and triploid hybrids, excepting a 10 bp of polyA insertion in type II sequence of the chimera of the diploid hybrids.

Conclusions
This is the first report of diploid and triploid hybrids being produced by crossing GC and BSB, which have the same chromosome number. The obtainment of two new hybrid offspring has significance in fish genetic breeding. The results illustrate the effect of hybridization and polyploidization on the organization and variation of 5S rDNA in hybrid offspring.

AbstractBackgroundPsoriasis is a chronic autoimmune disease in which T cells have a predominant role in initiating and perpetuating the chronic inflammation in skin. However, the mechanisms that regulate T cell activation in psoriasis are still incompletely understood. The objective of the present study was to characterize the main genetic pathways associated with T cell activation in psoriasis.ResultsGene expression profiles fromin vitroactivated T cells were obtained from 17 psoriasis patients and 7 healthy controls using Illumina HT-12 v4 microarrays. From a total of 47,321 analyzed transcripts, 42 genes were found to be differentially expressed between psoriasis and controls (FDR p-value < 0.1, absolute fold-change > 1.2). Using an independent cohort of 8 patients and 8 healthy controls we validated the overexpression ofSPATS2L(p-value =0.0009) andKLF6(p-value =0.0012) genes in activated T cells from psoriasis patients. Using weighted correlation analysis we identifiedSPATS2LandKLF6coexpression networks, which were also significantly associated with psoriasis (p-value < 0.05). Gene Ontology analysis allowed the identification of several biological processes associated with each coexpression network. Finally, using Gene Set Enrichment Analysis over the global T cell transcriptome we also found additional genetic pathways strongly associated with psoriasis (p-value < 0.0001).ConclusionsThis study has identified two new genes,SPATS2LandKLF6, strongly associated with T cell activation in psoriasis. Functional analyses of the gene expression profiles also revealed new biological processes and genetic pathways associated with psoriasis. The results of this study provide an important insight into the biology of this common chronic inflammatory disease.
An ERP-study of brand and no-name products

Published: November 2013

Abstract

Background
Brands create product personalities that are thought to affect consumer decisions. Here we assessed, using the Go/No-go Association Task (GNAT) from social psychology, whether brands as opposed to no-name products are associated with implicit positive attitudes. Healthy young German participants viewed series of photos of cosmetics and food items (half of them brands) intermixed with positive and negative words. In any given run, one category of goods (e.g., cosmetics) and one kind of words (e.g., positive) had to be responded to, whereas responses had to be withheld for the other categories. Event-related brain potentials were recorded during the task.

Results
Unexpectedly, there were no response-time differences between congruent (brand and positive words) and incongruent (brand and negative words) pairings but ERPs showed differences as a function of congruency in the 600–750 ms time-window hinting at the existence of implicit attitudes towards brand and no-name stimuli. This finding deserves further investigation in future studies. Moreover, the amplitude of the late positive component (LPC) was found to be enhanced for brand as opposed to no-name stimuli.

Conclusions
Congruency effects suggest that ERPs are sensitive to implicit attitudes. Moreover, the results for the LPC imply that pictures of brand products are more arousing than those of no-name products, which may ultimately contribute to consumer decisions.
