âThe Fall of the House of Usherâ: Poeâs perverted perspective on the âMaimed Kingâ
The themes of medieval literature had a profound effect on the works that would follow in later generations regardless of the writerâs recognition of this influence, and one can see the way Poe leaves traces of the popular medieval motif of the âMaimed Kingâ in his short story, âThe Fall of the House of Usherâ. This thematic device, which predates the medieval period, gained prominence in the tales of King Arthur and the Grail Quest. Although there is no clear indication that Poe intentionally set out to create a gothic rendition of this traditional theme, that does not discount the possibility of âUsherâ having been conditioned in some respect by this medieval notion. Through implementing a close reading of the story and comparing it to a framework of this conception of the âMaimed Kingâ, this paper points out a number of striking similarities between the two, as well as demonstrates the far-reaching influence of medievalism in one of nineteenth-century Americaâs preeminent fiction writers, Edgar Allan Poe

Bariatric surgery and low back pain: a systematic literature review
It is estimated that one third of the world population is overweight and 20% of adults have some low back symptoms at some point of their lives. The association of obesity and low back pain and physical deterioration has been well established. We designed this study to evaluate the role of bariatric surgery (BS) for lumbar spine symptoms in obese patients. A systematic literature review was performed using the PubMed database identifying lumbar spine symptoms (pain, functional status, disability index) and/or complications of lumbar spine surgery before and after BS. Study quality was assessed according to the Oxford Centre for Evidence-Based Medicine. Ten studies were identified. Nine evaluated the role of BS in low back pain and/or functional status before and after surgery: all reported that bariatric surgery had a positive impact in improving low back pain symptoms and decreasing disability in severely obese patients. One study evaluated the role of posterior lumbar surgery in patients who were obese at the time of surgery and those who had a previous bariatric procedure: bariatric surgery decreased postoperative surgical complications. The level of the evidence was low (III and IV). Bariatric surgery in severely obese patients decreases the intensity of low back symptoms and also decreases disability secondary to back problems. Additionally, bariatric surgery may be advantageous for patients who need a posterior lumbar surgery and are severely obese. Prospective studies with longer follow-up are necessary to confirm this conclusion.10110211

Outcome of Men Presenting with Clinical Breast Problems: The Role of Mammography and Ultrasound
The purpose of this study was to determine the outcome of men presenting with clinical breast problems for breast imaging and to evaluate the role of mammography and ultrasound in the diagnosis of benign and malignant breast problems. We retrospectively reviewed clinical, radiographic, and pathologic records of 165 consecutive symptomatic men presenting to Breast Imaging over a 4 year period. We assessed the clinical indication for referral, mammographic findings, sonographic findings, histologic results, and clinical outcomes. Patients ranged in age from 22 to 96 years. Breast Imaging Reporting and Data System (BI-RADS) category 4 and 5 mammograms and solid sonographic masses were considered suspicious for malignancy. Six of 165 men (4%) had primary breast carcinoma, which were mammographically suspicious in all 6 (100%). Five were invasive ductal carcinoma and one was ductal carcinoma in situ (DCIS). Of 164 mammograms, 20 (12%) were suspicious. Six were cancer and 14 were benign. Clinical follow-up for 2 years or biopsy results were available for 138 of the 165 men (84%). Twelve with benign mammographic findings had benign biopsies. All men with benign mammography not undergoing biopsy were cancer free. Sensitivity for cancer detection (mammography) was 100% and specificity was 90%. Positive predictive value (mammography) was 32% (6 of 19) and the negative predictive value was 100%. Sonography was performed in 68 of the 165 men (41%). Three of three cancers (100%) were solid sonographic masses. There were 9 of 68 false-positive examinations (13%). Sensitivity and negative predictive value for cancer detection (ultrasound) was 100% and specificity was 74%. The most common clinical indication for referral was mass/thickening (56%). Mammography had excellent sensitivity and specificity for breast cancer detection and should be included as the initial imaging examination of men with clinical breast problems. The negative predictive value of 100% for mammography suggests that mammograms read as normal or negative need no further examination if the clinical findings are not suspicious. A normal ultrasound in these men confirms the negative predictive value of a normal mammogram.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/74705/1/j.1075-122X.2006.00298.x.pd
