Colonoscopy based colitis surveillance is widely accepted to try to prevent development of and ensure early detection of colitis-associated colorectal cancer. Traditionally this has been performed with quadrantic random biopsies throughout the colon. Chromoendoscopy "dye-spray" with targeted biopsies only has been shown to increase dysplasia detection 4 to 5 fold on a per lesion basis. It has therefore been suggested that random biopsies should be abandoned as they do not increase dysplasia detection nor change patient clinical course. Recent British guidelines for colitis surveillance have strongly endorsed chromoendoscopy. This short review summarizes current international guidelines and looks at how to optimize white light colonoscopy in colitis considering: bowel preparation, withdrawal time, high definition, and structure enhancement. Data for advanced imaging techniques are reviewed including positive evidence in favor of chromoendoscopy, and limited data suggesting autofluoresence imaging may be promising. Narrow band imaging does not increase dysplasia detection in colitis. Confocal endomicroscopy might potentially reduce biopsies beyond that of chromoendoscopy but does not offer a clear detection advantage. Pan-colonic chromoendoscopy with targeted biopsies increases dysplasia detection and is the standard of care in the United Kingdom. It is likely that the use of chromoendoscopy for colitis surveillance will become widely accepted internationally.

This study provides a closer look to the possibility of having advanced practice in public health nursing by analyzing the power relations between nursing practice and social structures. Representatives from the public health sector, national authorities, and the private sector were invited in a round table discussion. Transcriptions were coded and later on categorized and analyzed drawing upon the concepts of Foucault. Foucauldian analysis hands an important insight on how social structures and institutions can steer the creation of an advanced practice in public health nursing in the Philippines. Various social institutions view the relevance of a master's prepared nurse according to their societal roles and functions. Requisite competencies of a master's prepared nurse in public health nursing include fulfilling the role of a clinician, leader and manager, supervisor, and a researcher. PRBON, CHED, DOH, and nursing schools need to work together to define the knowledge of an advanced practice in public health nursing, to implement appropriate surveillance mechanisms, and to establish a compliant practice.

Monoclonal gammopathy of renal significance is defined as any B cell or plasma cell clonal lymphoproliferation which neither causes tumor complications nor meets any current hematological criteria for specific therapy, with one or more kidney lesions related to the produced monoclonal immunoglobulin, such as amyloidosis. A 50-year-old male presented with heavy proteinuria and blood tests showing IgA and Lambda paraproteinemia. Light microscopy showed mesangial eosinophilic ground substance extending into the capillary loops, and positive staining within the glomeruli and vessel walls for amyloid P immunohistochemistry was also noted. Immunofluorescence showed positive staining for IgA and Lambda in the mesangia and capillary loops. Electron microscopy exhibited organized fibrils measuring 4–5 nm in diameter in the mesangia, glomerular basement membranes and vessel walls. We interpreted the overall findings as atypical renal amyloidosis with IgA and Lambda deposition on immunofluorescence. Further amyloid typing using laser microdissection-liquid chromatography and mass spectrometry will be useful.

BACKGROUND: Massive retracted rotator cuff tears represent a therapeutic dilemma, particularly in the young and middle-aged patients who are not appropriate for a reverse total shoulder replacement. Interposition grafting using human dermal allograft offers an alternative treatment. METHODS: A retrospective review of all patients who underwent interposition grafting using human dermal allograft between December 2013 and May 2015 for massive rotator cuff tears at our tertiary referral center was performed. Preoperative and 6 month postoperative magnetic resonance imaging (MRI) assessments were performed in all patients, with postoperative graft integrity being the primary outcome measure. Clinical evaluation was performed using the Oxford shoulder score, Constant score, and Disabilities of the Arm, Shoulder and Hand (DASH) score. RESULTS: The mean age at the time of follow-up was 54 years. On MRI, 84% of grafts were seen to have failed at 6 months. Strength was grossly reduced on the operative side when supraspinatus and subscapularis were tested; despite this, Constant score (mean, 48.2) was comparable to that in the previous reports. DASH and Oxford scores were a mean of 24.94 and 37.16, respectively. CONCLUSIONS: Based on these results, in particular the MRI findings, we cannot advocate the use of dermal allograft as an interposition graft for the repair of massive rotator cuff tears.

Background/Aims: STRETTA improves the quality of life and reduces the need for anti-reflux medication in select patients, especially those with uncomplicated gastro-esophageal reflux disease (GERD). We aimed to review the outcomes of STRETTA in patients with medically refractory GERD, who had undergone previous gastric surgery. Methods: This was a review of a prospective database in a British center. Since 2016, all GERD patients who underwent STRETTA and had a history of previous gastric surgery were studied (n=11). Anti-reflux medication pre- and post-STRETTA was evaluated. The outcomes were assessed objectively by the change in anti-reflux medication and subjectively through a pre- and post-procedure GERD-health-related quality of life (HRQL) questionnaire. Results: The median length of follow-up was 23 months. Nine patients demonstrated improved GERD-HRQL scores following STRETTA (82%). Of the 7 patients who underwent fundoplication, all reported improved symptoms, with 3 patients discontinuing the medication and 3 patients on a reduced dose of proton pump inhibitor. Four patients underwent surgery other than fundoplication, of which 2 reported improvement and discontinued the proton pump inhibitor. Two patients reported no improvement. Conclusions This study demonstrates that STRETTA is successful in reducing refractory GERD in patients with previous gastric surgery. The outcomes were comparable to published outcomes in patients with uncomplicated GERD with no previous history of gastric surgery.

A 26-year-old male member of the Australian Defense Force presented with a history of central abdominal pain of 4 weeks duration and peripheral eosinophilia consistent with eosinophilic enteritis. Acute hookworm disease was diagnosed as the cause. Adult worms recovered from feces after therapy with albendazole were morphologically consistent with Ancylostoma ceylanicum. As the patient had been deployed with the Regional Assistance Mission to Solomon Islands for 6 months prior to this presentation, it is very likely that the A. ceylanicum was acquired in Solomon Islands. Until now, it has been assumed that any Ancylostoma spp. recovered from humans in Solomon Islands is A. duodenale. However, this case demonstrates that human hookworm infection acquired in the Solomon Islands could be caused by A. ceylanicum.

BACKGROUND: Although safe and effective, a wide array of complications of esophageal stent placement continues to pose a significant challenge to clinicians in providing optimal care for their patients. METHODS: To identify factors associated with migration of self-expandable metal stent (SEMS) used in treating malignant and benign disease of esophagus, a retrospective study analyzing 105 cases (85 patients) of esophageal SEMS placement between January 2013 and June 2015 was conducted. All cases were performed in a single tertiary referral center. The key outcomes of interest were SEMS migration rates based on indication, stent type, design, and endoscopic findings prior to SEMS placement. Technical success rate, other major adverse outcomes and subgroup analysis of interest were also performed. RESULTS: Overall esophageal SEMS migration rate was 26.7%. Significantly higher rates of stent migration were associated with fully covered stent use (38.1% vs 9.5%, P = 0.001) and stent use in benign conditions (43.9% vs 15.6%, P = 0.002). Our multivariable analysis also showed statistically significant increased risk of migration for SEMS placement in distal esophagus (P = 0.006). CONCLUSIONS: This study validated some of previously reported predictors of stent migration. In addition, stent use in benign esophageal disease was found to be a significant risk factor of SEMS migration. Large, prospective studies are necessary to further clarify modifiable risk factors to reduce the rate of SEMS migration.
