Abstract
BACKGROUND Clear cell sarcomas (CCSs) are translocated aggressive malignancies, most commonly affecting young adults with a high incidence of metastases and a poor prognosis. Research into the disease is more feasible when adequate models are available. By establishing CCS cell lines from a primary and metastatic lesion and isolating healthy fibroblasts from the same patient, the in vivo process is accurately reflected and aspects of clinical multistep carcinogenesis recapitulated. METHODS Isolated tumor cells and normal healthy skin fibroblasts from the same patient were compared in terms of growth behavior and morphological characteristics using light and electron microscopy. Tumorigenicity potential was determined by soft agar colony formation assay and in vivo xenograft applications. While genetic differences between the two lineages were examined by copy number alternation profiles, nuclear magnetic resonance spectroscopy determined arginine methylation as epigenetic features. Potential anti-tumor effects of a protein arginine N-methyltransferase type I (PRMT1) inhibitor were elicited in 2D and 3D cell culture experiments using cell viability and apoptosis assays. Statistical significance was calculated by one-way ANOVA and unpaired t-test. RESULTS The two established CCS cell lines named MUG Lucifer prim and MUG Lucifer met showed differences in morphology, genetic and epigenetic data, reflecting the respective original tissue. The detailed cell line characterization especially in regards to the epigenetic domain allows investigation of new innovative therapies. Based on the epigenetic data, a PRMT1 inhibitor was used to demonstrate the targeted antitumor effect; normal tissue cells isolated and immortalized from the same patient were not affected with the IC50 used. CONCLUSIONS MUG Lucifer prim, MUG Lucifer met and isolated and immortalized fibroblasts from the same patient represent an ideal in vitro model to explore the biology of CCS. Based on this cell culture model, novel therapies could be tested in the form of PRMT1 inhibitors, which drive tumor cells into apoptosis, but show no effect on fibroblasts, further supporting their potential as promising treatment options in the combat against CCS. The data substantiate the importance of tailored therapies in the advanced metastatic stage of CCS.

Abstract
BACKGROUND Skin cancer is one of the most common cancers in the UK. Patients with suspicious skin lesions are assessed clinically with/without dermoscopy, and lesions still considered suspicious are then surgically removed or have the diagnosis confirmed by a punch biopsy. AIM To evaluate the diagnostic accuracy of the in vivo VivaScope© reflective confocal microscopy (RCM) system, a noninvasive technology designed to provide a more accurate presurgical diagnosis, leading to fewer biopsies of benign lesions, or to provide greater accuracy for lesion margins. METHODS MEDLINE, EMBASE and the Cochrane Library were searched to identify studies evaluating dermoscopy plus RCM, or RCM alone, with histopathology as the reference test. Clinical experts were also contacted for information on unpublished studies. RESULTS Eleven studies met the inclusion criteria but were too heterogeneous to be combined by meta-analysis. Results indicated that VivaScope subsequent to dermoscopy may improve diagnostic accuracy of malignant melanomas compared with dermoscopy. For margin delineation, the data suggest that mapping using VivaScope 1500 for lentigo maligna (LM) and LM melanoma may improve accuracy in terms of complete excision of lesions compared with dermoscopically determined margins. For basal cell carcinoma, the limited data show high diagnostic accuracy with both VivaScope 1500 and VivaScope 3000. Evidence on the effectiveness of VivaScope in diagnosing cutaneous squamous cell carcinomas was very limited. CONCLUSION The use of VivaScope 1500 following dermoscopy may improve patient care and management of suspicious skin lesions, although the generalizability of these results to the UK population remains unclear.

Abstract
OBJECTIVES Cochrane Reviews should address the most important questions for guideline writers, clinicians, and the public. It is not possible to keep all reviews up-to-date, so the Cochrane Airways Group (CAG) decided to prioritize updates and new reviews without requesting additional resources. The aim of the objective was to develop pragmatic and transparent prioritization techniques to identify 25 to 35 high-priority updates from a total of 270 CAG Reviews and become more selective over which new reviews we publish. STUDY DESIGN AND SETTING We used elements from existing prioritization processes, including existing health care uncertainties, expert opinion, and a decision tool. We did not conduct a full face-to-face workshop or an iterative group decision-making process. RESULTS We prioritized 30 reviews in need of updating and aimed to update these within 2 years. Within the first 18 months, nine of these have been published. CONCLUSION A pragmatic approach to prioritization can indicate priority reviews without an excessive drain on time and resources. The steps provide us with better control over the reviews in our scope and can be built on in the future.

Abstract
OBJECTIVES This paper describes the natural course of irritable hip pain associated with spinal rigidity and pain in the thoracic region with subsequent development of mild kyphosis in a girl with a mutation in the collagen 2 alpha 1 gene (type II collagenopathy). METHODS Phenotypic and genotypic characterization was carried out in a 14-year-old girl to identify the underlying pathology of severe irritable hip pain associated with thoracic spinal rigidity and pain. Detailed clinical examination, skeletal survey and genetic testing were performed accordingly. Bernese periacetabular osteotomy was used to alleviate pain and to improve the anatomical correlation of the acetabular and femoral heads. RESULTS Short stature associated with acetabulo-femoral dysplasia, spinal osteochondritis (Scheuermann's disease) and mild thoracic kyphosis were the most prominent abnormalities. Genetic analysis showed a heterozygous mutation in the collagen type II gene (COL2A1-c.1636G>A, p. G546S). A Bernese periacetabular osteotomy was performed to improve the clinical status of the patient. There was significant improvement in the extrusion index, the acetabular index and the lateral center-edge angle. CONCLUSIONS Hip dysplasia and Scheuermann's osteochondritis have never been reported in connection with a mutation in COL2A1 (collagenopathy type II). Awareness is needed for careful phenotypic and genotypic characterization in patients with irritable hip pain and spinal stiffness.
