Patients with inflammatory bowel disease colitis have an increased risk of developing colorectal cancer compared with the general population. Colonoscopic surveillance remains challenging because the cancer precursor (dysplasia) can have a varied and subtle endoscopic appearance. Although historically the dysplasia was often considered endoscopically invisible, today with advanced endoscopic understanding, technique, and imaging, it is almost always visible. The frequency of different dysplasia morphologies and true clinical significance of such lesions are difficult to determine from retrospective series, many of which were performed prior to the current endoscopic era. © 2014 Elsevier Inc.

Background: Three forms of asbestos-related benign pleural disease are recognized: discrete pleural plaques, pleural effusions and diffuse pleural fibrosis. Of these, diffuse pleural fibrosis is the most significant on account of its chronicity and associated morbidity. Aims: The objectives of this study were to determine the latency of asbestos-induced diffuse pleural fibrosis, its presenting features and its clinical course once established. Methods: We conducted a retrospective review of 75 patients with asbestos-induced diffuse pleural fibrosis referred for assessment at our institution from 1992 to 2007. Diffuse pleural fibrosis was considered to be present if there was obliteration of the costophrenic angle in continuity with at least 3-mm pleural thickening, in accordance with the International Labour Organization 2000 Classification. Results: The median latency for development of diffuse pleural fibrosis from first asbestos exposure was 34 years. Seventy-three per cent of patients had unilateral disease at presentation and 24% of these were observed to develop contralateral disease after a median of 2 years. Unilateral pleural disease was commonest on the right. Forty per cent of patients presented with pleural effusions preceding the development of diffuse pleural thickening. The median latency for development of pleural effusions from onset of exposures was 38 years. Eighty per cent of the pleural effusions were unilateral. Once established, pleural thickening was reported to have remained stable in 91% on the ipsilateral side. Conclusions: The findings of this study may help in providing further insight into the natural history of diffuse pleural fibrosis to guide the clinician in the management of this condition. © The Author 2012.

We present the clinical results and survivorship of consecutive 100 Birmingham Hip Resurfacings in 90 patients at a minimum follow-up of ten years. All procedures were carried out by an independent surgeon who commenced a prospective study in 1998. Patients were assessed clinically using the Western Ontario and McMaster Universities osteoarthritis index, Short-Form 36, Harris hip score and University of California, Los Angeles activity score. Radiological analysis was performed by an independent observer and blood metal ion levels concentrations were measured at ten years post-operatively in 62 patients. The median acetabular component inclination was 46.2° (34° to 59°) and anteversion 11.0° (0° to 30°). The median chromium concentration in the unilateral group was 1.74 (0.41 to 15.23) and for the bilateral group was 2.98 (1.57 to 18.01). The equivalent values for cobalt were 1.67 (0.54 to 20.4) and 1.88 (1.38 to 19.32). In total there were eight failures giving an overall survival at ten years of 92% (95% confidence interval (CI) 86.7 to 97.3). BHR in male patients had an improved survivorship of 94.6% (95% CI 89.4 to 100) compared with females at 84.6% (95% CI 70.7 to 98.5), but this did not reach statistical significance (p = 0.119). Four of the nine BHRs with a bearing diameter of 42 mm failed. The overall results were consistent with data produced from other centres in that the clinical outcome of large male patients was extremely encouraging, whereas the survival of the smaller joints was less satisfactory. ©2012 British Editorial Society of Bone and Joint Surgery.

Introduction: The Bowel Cancer Screening Programme in England began operating in 2006 with the aim of full roll out across England by December 2009. Subjects aged 60-69 are being invited to complete three guaiac faecal occult blood tests (6 windows) every 2 years. The programme aims to reduce mortality from colorectal cancer by 16% in those invited for screening. Methods: All subjects eligible for screening in the National Health Service in England are included on one database, which is populated from National Health Service registration data covering about 98% of the population of England. This analysis is only of subjects invited to participate in the first (prevalent) round of screening. Results: By October 2008 almost 2.1 million had been invited to participate, with tests being returned by 49.6% of men and 54.4% of women invited. Uptake ranged between 55-60% across the four provincial hubs which administer the programme but was lower in the London hub (40%). Of the 1.08 million returning tests 2.5% of men and 1.5% of women had an abnormal test. 17 518 (10 608 M, 6910 F) underwent investigation, with 98% having a colonoscopy as their first investigation. Cancer (n=1772) and higher risk adenomas (n=6543) were found in 11.6% and 43% of men and 7.8% and 29% of women investigated, respectively. 71% of cancers were 'early' (10% polyp cancer, 32% Dukes A, 30% Dukes B) and 77% were left-sided (29% rectal, 45% sigmoid) with only 14% being right-sided compared with expected figures of 67% and 24% for left and right side from UK cancer registration. Conclusion: In this first round of screening in England uptake and fecal occult blood test positivity was in line with that from the pilot and the original European trials. Although there was the expected improvement in cancer stage at diagnosis, the proportion with left-sided cancers was higher than expected.

Early failure associated with adverse reactions to metal debris is an emerging problem after hip resurfacing but the exact mechanism is unclear. We analysed our entire series of 660 metal-on-metal resurfacings (Articular Surface Replacement (ASR) and Birmingham Hip Resurfacing (BHR)) and large-bearing ASR total hip replacements, to establish associations with metal debris-related failures. Clinical and radiological outcomes, metal ion levels, explant studies and lymphocyte transformation tests were performed. A total of 17 patients (3.4%) were identified (all ASR bearings) with adverse reactions to metal debris, for which revision was required. This group had significantly smaller components, significantly higher acetabular component anteversion, and significantly higher whole concentrations of blood and joint chromium and cobalt ions than asymptomatic patients did (all p < 0.001). Postrevision lymphocyte transformation tests on this group showed no reactivity to chromium or cobalt ions. Explants from these revisions had greater surface wear than retrievals for uncomplicated fractures. The absence of adverse reactions to metal debris in patients with well-positioned implants usually implies high component wear. Surgeons must consider implant design, expected component size and acetabular component positioning in order to reduce early failures when performing large-bearing metal-on-metal hip resurfacing and replacement. ©2010 British Editorial Society of Bone and Joint Surgery.

The management of erectile dysfunction (ED) has been revolutionized by the discovery of phosphodiesterase 5 (PDE5) inhibitors, which have been commercially available for more than a decade and are the first-line therapeutic option for men with ED. Sildenafil, vardenafil and tadalafil were approved by the European Medicine Agency and the US FDA for the treatment of ED on the back of their high efficacy rates and favorable safety profiles. However, despite the fact that more than 50 million patients with ED worldwide have been successfully treated with one of these PDE5 inhibitors, some men-most notably those with severe neurologic damage, diabetes mellitus or severe vascular disease-are resistant to the currently available drugs and require more-invasive treatments, such as intracavernosal injection therapy. Partly as a consequence of this, research into alternative therapeutic approaches continues, including the development of new PDE5 inhibitors, centrally acting pharmaceutical agents, and application of molecular technologies such as gene therapy and stem cell therapy. © 2010 Macmillan Publishers Limited.

We present the early clinical and radiological results of Articular Surface Replacement (ASR) resurfacings in 214 hips (192 patients) with a mean follow-up of 43 months (30 to 57). The mean age of the patients was 56 years (28 to 74) and 85 hips (40%) were in 78 women. The mean Harris hip score improved from 52 (11 to 81) to 95 (27 to 100) at two years and the mean University of California, Los Angeles activity score from 3.9 (1 to 10) to 7.4 (2 to 10) in the same period. Narrowing of the neck (to a maximum of 9%) was noted in 124 of 209 hips (60%). There were 12 revisions (5.6%) involving four (1.9%) early fractures of the femoral neck and two (0.9%) episodes of collapse of the femoral head secondary to avascular necrosis. Six patients (2.8%) had failure related to metal wear debris. The overall survival for our series was 93% (95% confidence interval 80 to 98) and 89% (95% confidence interval 82 to 96) for hips with acetabular components smaller than 56 mm in diameter. The ASR implant has a lower diametrical clearance and a subhemispherical acetabular component when compared with other more frequently implanted metal-on-metal hip resurfacings. These changes may contribute to the higher failure rate than in other series, compared with other designs. Given our poor results with the small components we are no longer implanting the smaller size. ©2010 British Editorial Society of Bone and Joint Surgery.

To compare shoulder ultrasonography with arthroscopy for detecting specific rotator cuff tears. 96 shoulders in 56 men and 34 women aged 28 to 65 (mean, 42) years with rotator cuff problems underwent a shoulder ultrasonography by a single radiologist, and then a shoulder arthroscopy by a single surgeon. The ultrasonographic and arthroscopic findings were compared with regard to tendon-specific tears and disparities in diagnosis. For detection of supraspinatus tendon tears, ultrasonography attained a sensitivity of 89%, specificity of 43%, positive predictive value of 76%, and negative predictive value of 100%. For detection of subscapularis tendon tears, ultrasonography attained a sensitivity of 30%, specificity of 100%, positive predictive value of 100%, and negative predictive value of 78%. Sensitivity, specificity, and predictive values were good in larger full-thickness tears, but were significantly reduced in sub-centimetre and partial-thickness tears, particularly of the subscapularis tendon. Surgeons should be aware of the potential disparities between ultrasonographic and arthroscopic findings and be prepared to adjust the surgical procedure during arthroscopy.

The association between inflammatory bowel disease (IBD) and colorectal cancer (CRC) has been recognised since 1925 and still accounts for 10%-15% of deaths in IBD. IBD-associated CRC (IBD-CRC) affects patients at a younger age than sporadic CRC. The prognosis for sporadic CRC and IBD-CRC is similar, with a 5-year survival of approximately 50%. Identifying at risk patients and implementing appropriate surveillance for these patients is central to managing the CRC risk in IBD. The increased risk of colorectal cancer in association with IBD is thought to be due to genetic and acquired factors. The link between inflammation and cancer is well recognised but the molecular biology, immune pathobiology and genetics of IBD-CRC are areas of much ongoing research. This review examines the literature relating to IBD-CRC, focusing on the incidence of IBD-CRC and examining potential risk factors including age at diagnosis, gender, duration and extent of colitis, severity of inflammation, family history of sporadic CRC and co-existent primary sclerosing cholangitis (PSC). Confirmed risk factors for IBD-CRC are duration, severity and extent of colitis, the presence of co-existent PSC and a family history of CRC. There is insufficient evidence currently to support an increased frequency of surveillance for patients diagnosed with IBD at a younger age. Evidence-based guidelines advise surveillance colonoscopy for patients with colitis 8 to 10 years after diagnosis, with the interval for further surveillance guided by risk factors (extent of disease, family history of CRC, post-inflammatory polyps, concomitant PSC, personal history of colonic dysplasia, colonic strictures). There is a move away from using random colonic biopsies towards targeted biopsies aimed at abnormal areas identified by newer colonoscopic techniques (narrow band imaging, chromoendoscopy, confocal microendoscopy). © 2012 Baishideng.

To estimate the prevalence of insomnia in patients with chronic back pain, and to correlate insomnia with severity of back pain and disability. 63 women and 57 men aged 24 to 83 (mean, 55) years who presented with chronic back pain for >6 months were asked to complete a self-administered questionnaire to evaluate the Insomnia Severity Index (ISI), Oswestry Disability Index (ODI), and Numerical Rating Scale (NRS) for back pain. Of the 120 patients, 25 had no insomnia, 39 had sub-threshold insomnia, and 56 had clinically significant insomnia. According to the ODI, disability was minimal in 12 patients, moderate in 38, severe in 43, bed-binding in 26, and crippling in one. Of the 120 patients, 91 rated their NRS for back pain as 5 to 10 and 29 rated it as 1 to 4. Correlation was stronger between ISI and ODI than between ISI and NRS for back pain (r=0.59 vs. r=0.38). 47% of patients with chronic back pain had insomnia. The ODI was more reliable than the NRS for back pain to detect insomnia. Back pain should be treated early to avoid serious health problems associated with insomnia.
