    Barium enema and colonoscopy: appropriateness of utilization in a Medicaid population (1997)

    Notes: Abstract. Background: To assess the appropriateness of utilization patterns for the barium enema and colonoscopy in a Medicaid population. Methods: From 1987 to 1991, a Medicaid managed-care database in Philadelphia revealed claims for a total of 2357 outpatient barium enemas and 896 outpatient colonoscopic examinations. The database was reviewed to determine the primary diagnostic (ICD-9-CM) codes assigned to patients who underwent these procedures. These codes were used as a proxy for indications. Each of the diagnostic codes for barium enema and colonoscopy was then classified either as appropriate, inappropriate, equivocal, or miscoded based on current guidelines in the medical literature. Results: A total of 1962 claims (83%) for barium enema were classified as appropriate, 126 (5%) as inappropriate, 84 (4%) as equivocal, and 185 (8%) as miscoded, whereas 645 claims (72%) for colonoscopy were classified as appropriate, 176 (20%) as inappropriate, 65 (7%) as equivocal, and 10 (1%) as miscoded. Thus, significantly more colonoscopic examinations were rated as inappropriate (p 〈 0.001). Conclusion: Our study suggests that more stringent criteria need to be used by physicians in ordering diagnostic examinations of the colon, particularly colonoscopy. Further investigation of the appropriateness of these procedures and the development and dissemination of guidelines seems warranted.

    Solitary ulcers in reflux esophagitis: radiographic findings (1997)
    Springer
    Abdominal imaging 22 (1997), S. 5 -7 
    Details
    ISSN: 1432-0509
    Keywords: Key words: Reflux esophagitis—Gastroesophageal reflux disease—Esophageal ulcers. [xm [fs99]
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Abstract. Background: Some patients with reflux esophagitis have solitary ulcers in the distal esophagus. This study was undertaken to characterize further the radiographic features of these ulcers and to determine whether or not they have a predisposition to develop on the posterior esophageal wall. Methods: Radiologic files and teaching files at our university hospital and affiliated Veterans Administration hospital revealed 29 patients with solitary reflux-induced ulcers. The radiographs were reviewed retrospectively to determine the size and location of the ulcers as well as the presence or absence of other findings. Results: Twenty ulcers (69%) were located on the posterior wall, five (17%) on the left or right lateral wall, and four (14%) on the anterior wall. All but two ulcers were located 1–4 cm from the gastroesophageal junction. All of the ulcers were less than 10 mm in width and 5 mm in depth. Other associated findings included hiatal hernias in 11 patients (38%), mucosal nodularity or granularity in 12 (41%), one or more tiny satellite ulcers in three (10%), esophageal intramural pseudodiverticula in three (10%), an inflammatory esophagogastric polyp in one (3%), and scarring or stricture formation in 12 (41%). Conclusion: Our findings suggest that solitary reflux-induced ulcers tend to occur on the posterior wall of the distal esophagus near the gastroesophageal junction, producing characteristic radiographic findings. We postulate that affected individuals sleep primarily in the supine position, so that refluxed acid pools on the dependent or posterior esophageal wall, causing maximal injury in this location.

    Total proctocolectomy and ileoanal pouch: the role of contrast studies for evaluating postoperative leaks (1998)

    Keywords: Key words: Proctocolectomy—Ileoanal pouch.

    Notes: Abstract. Background: To assess the role of contrast enemas for the evaluation of leaks in symptomatic and asymptomatic patients after the first stage of restorative proctocolectomy. Methods: We reviewed the findings of 59 contrast enemas in 40 patients who underwent total proctocolectomy with creation of an ileoanal pouch and a proximal diverting ileostomy. Thirty-seven patients initially underwent routine contrast studies of the ileoanal pouch, and three underwent contrast studies because of suspected fistulas or obstruction. Medical records were also reviewed to determine the clinical presentation and course of these patients. Results: Of 37 patients who underwent routine postoperative contrast enemas, 33 (89%) had normal studies, three (8%) had clinically silent leaks (including two blind-ending tracks from the ileoanal anastomosis and one from the pouch), and one (3%) had pouchitis. In all three patients with unsuspected leaks, ileostomy closure was delayed. In two other patients with abdominal pain and fever, contrast enemas revealed leaks from the ileoanal pouch and distal ileum, respectively. The remaining patient had a contrast enema because of abdominal pain and distention; this patient had a distal ileal obstruction due to adhesions. Conclusions: Routine postoperative contrast studies revealed clinically silent leaks from the ileal J pouch or ileoanal anastomosis in three of 37 patients (8%) after the first stage of restorative proctocolectomy. Our findings suggest that routine contrast enema can detect clinically silent leaks after this surgery.

    Notes: Abstract An infant is presented who at birth met criteria consistent with hypoplastic left heart syndrome. He was followed clinically and by 11 weeks of age demonstrated substantial growth of the left ventricle. He underwent successful repair of coarctation of the aorta and continues to do well with moderate aortic stenosis. The difficulties of predicting left ventricular growth and function are discussed, and management options are reviewed.

    Notes: Abstract. Respiratory syncytial virus (RSV) is a common cause of lower respiratory infections in infants. Cardiac arrhythmias are an uncommon complication in infants with RSV bronchiolitis. Presumably, the arrhythmias may be secondary to RSV pericarditis, myocarditis, or some other infection of the heart. We report on a patient with RSV bronchiolitis who had clinical myocarditis complicated by ventricular tachycardia.

    Notes: Abstract The utility of an electron beam ion trap (EBIT) as a source of highly charged ions for laser spectroscopy is discussed, with a view to measuring the 2s Lamb shift in a medium-Z hydrogenlike ion. Such an experiment could shed light on a small but systematic discrepancy between previous measurements and theory.

    Viable but non-culturable Vibrio cholerae O1 revert to a cultivable state in the human intestine (1996)

    Notes: Abstract Vibrio cholerae O1 can enter a state in which they remain viable but are non-culturable. Presumably, such bacteria can be pathogenic if they retain the capacity to proliferate in the human intestine following ingestion. Two groups of volunteeers were given inocula containing viable but non-culturable V. cholerae O1 of the attenuated vaccine strain CVD 101 (viable CVD 101 organisms readily colonize the human intestine). Volunteers in one of the two groups excreted viable CVD 101, demonstrating that, in the environment of the human intestine, previously non-culturable vibrios can regain the capacity to multiply. These observations support the proposition that viable but non-culturable bacterial enteropathogens may pose a potential threat to health.

    Surface-modified poly(methyl methacrylate) enhances adsorption and retains anticandidal activities of salivary histatin 5 (1995)

    Notes: Denture-induced stomatitis is a common intraoral disease which is associated with high levels of Candida albicans adhesion to a denture surface. The aim of this study was to produce a surface-modified denture resin, which is usually manufactured from poly(methyl methacrylate) (PMMA), carrying an immobilized anticandidal protein. PMMA was modified by surface polymerization of methyl methacrylic acid to enhance adsorption of a potent candidacidal salivary protein, histatin 5. The modified PMMA showed higher surface adsorption and desorption of histatin 5 than the unmodified material. Because histatin 5 destabilizes C. albicans cell membranes and allows efflux of intracellular molecules, candidacidal activity was monitored by dye release from fungal cells. Adsorbed histatin 5 did not release dye from the yeast cells; however, dye was detected as histatin was desorbed from the surface. In an adhesion assay, modified PMMA decreased human submandibular-sublingual saliva (HSMSL) mediated adherence of yeast cells to the polymer. Precoating histatin 5 onto unmodified PMMA also abolished HSMSL-mediated adhesion. These experiments show that dental acrylic may be surface modified and loaded with histatin 5 as a means of controlled release of histatin 5 to an affected area. This surface modification may additionally reduce adhesion of C. albicans cells to the saliva-coated material. © 1995 John Wiley & Sons, Inc.
