Analysis of Functional and Anatomic Success Following Endonasal Dacryocystorhinostomy

Objectives: The aim of this study was to assess the concomitant perioperative procedures, the causes of nasolacrimal duct obstruction, the success rate, and the complications associated with endonasal dacryocystorhinostomy (ENDCR).Methods: In this single-center retrospective study, 98 patients underwent 104 ENDCRs between January 1994 and February 2006. There were 78 patients with 84 nasolacrimal duct obstructions who were included in this study.Results: The overall functional success rate with improvement in symptoms was 94.9% for primary surgery (59 of 84 obstructions) and 63.6% for salvage surgery after failure of primary surgery performed in another hospital (25 of 84 obstructions). The mean follow-up time was 36.8 +/- 17.11 months. Primary surgery showed better results, with a complete success rate of 93.2%, than did salvage surgery, with a success rate of only 68%. Persistent symptoms, despite an open rhinostomy, were found in 1.7% of patients with primary surgery and in 12% of those with salvage surgery. Failure of ENDCR was observed in 3.4% of patients after primary surgery and in 20% after salvage surgery. We encountered only minimal perioperative complications, and these were essentially related to lacrimal intubation.Conclusions: Because of the possibility of treating concomitant sinonasal disorders, the cosmetic advantages, and the excellent results, ENDCR represents the procedure of choice for treating nasolacrimal duct obstructions. The main challenge lies in the exact preoperative assessment, as well as postoperative evaluation in case of failure.

Assessing medication adherence: options to consider.

Background Adherence to chronic therapy is a key determinant of patient health outcomes in chronic disease. However, only about 50 % of patients adhere to chronic therapy. One of the challenges in promoting adherence is having an accurate understanding of adherence rates and the factors that contribute to non-adherence. There are many measures available to assess patient medication adherence. Aim of the review This review aims to present the commonly used indirect methods available for measuring medication adherence in routine healthcare and research studies. Method A literature review on medication adherence measures in patient populations with chronic conditions taking chronic medications was conducted through Medline (2003-2013). A complementary manual search of references cited in the retrieved studies was performed in order to identify any additional studies. Results Of the 238 initial Medline search results, 57 full texts were retrieved. Forty-seven articles were included as a result of the manual search. Adherence measures identified were: self-report (reported in 50 publications), electronic measures (33), pharmacy refills and claims data (26) and pill counts (25). Patient self-report, electronic measures, pharmacy refill and claims data were the most commonly used measures of adherence in research, routine practice, epidemiological and intervention studies. These methods, and their strengths and limitations have been described in this paper. Conclusion A multitude of indirect measures of adherence exist in the literature, however, there is no "gold" standard for measuring adherence to medications. Triangulation of methods increases the validity and reliability of the adherence data collected. To strengthen the adherence data collected and allow for comparison of data, future research and practice interventions should use an internationally accepted, operational standardized definition of medication adherence and clearly describe the medication adherence methods used.

Genetic structure of the genus Leptospira by multilocus enzyme electrophoresis

Thirty strains from the 11 species of the genus Leptospira were studied by multilocus enzyme electrophoresis at 12 enzyme loci, all of which were polymorphic. The mean number of alleles per locus was 6.5. Twenty-five electrophoretic types were distinguished. Grouping of the strains by cluster analysis was in general agreement with species delineation as determined by DNA-DNA hybridization, except for the strains of Leptospira meyeri and Leptospira inadai, which were scattered throughout the genus, reflecting previously recognized taxonomic uncertainties. Analysis of the clonality within Leptospira interrogans sensu stricto indicated that this population was relatively heterogeneous and a lack of gene linkage disequilibrium could not be excluded. There was a genetic discrimination between the pathogenic species and the saprophytic ones. The phenotypically intermediate species (L. inadai and Leptospira fainei) were also genetically separated and were probably closer to the saprophytes than to the pathogens.

Chorioretinal lacuna in the amniotic band syndrome.

The malformations in the amniotic band syndrome (ABS) are due to entrapment of fetal parts by fibrous band in the amniotic sac. Limbs are most commonly affected followed by craniofacial defects in one third of patients. Ocular defects include corneal leukomas and lid colobomas often contiguous with facial clefts, strabismus, hypertelorism, and microphthalmos. Unilateral chorioretinal defects or lacunae are rare findings in the ABS. We report a female infant with such a lacunar defect along with central nervous abnormalities, and discuss the differential diagnosis and the embryopathic implications.

Els apareguts i el culte de les ànimes del Purgatori (segles XIV-XVII). Estudi i edició de textos catalans

Report for the scientific sojourn carried out at the Institut National d'Histoire de l'Art (INHA), France, from 2010 to 2012. It has focused on the analysis and editing of tales of human apparitions from the other world belonging to the Catalan culture or referring to it. We have studied and edited different versions of the process of Esperança Alegre (Lleida, 1500) and the Peregrinació del Venturós Pelegrí. These medieval works have been preserved in sources of the late sixteenth century or later. We have located a manuscript of the Esperança Alegre's tale, unknown to us at the beginning of this research (Biblioteca Nacional de España, ms. 1701), which differs from the version of ms. Baluze 238 of the Bibliothèque Nationale de France. The scribe of the ms. 1701 adds several paragraphs where considers the case as a diabolical phantasmagoria. About the Venturós Pelegrí, we have tried to establish firm criteria for the classification of many editions from the seventeenth to nineteenth centuries. We have been looking for printed books in the libràries of the world and we have made several requests for photographic reproductions, in order to classify undated editions by comparing woodcuts and other decorative elements. In the legend of Prince Charles of Viana (1421-1461), the appearances of his ghost are accompanied by rumors of his poisoning and of his sanctity. In addition, we have studied the cycles of masses for the souls in Purgatory linked to the hagiographies of St. Amadour and St. Vincent Ferrer, as well as the appearances described in L'Ànima d’Oliver of Francesc Moner, in the Carmelite chronicles of Father John of St. Joseph (1642-1718) and in some folktales collected from the eighteenth to the twentieth century. All this have allowed us to verify the evolution of certain cultural paradigms since the Middle Ages to the present.

Knowledge and attitude regarding standard precautions in a Brazilian public emergency service: a cross-sectional study

The purpose of this study was to assess the knowledge and attitude of health care professionals regarding their use of universal precaution measures at a public emergency service. The study also aimed to assess the rates of occupational accidents involving biological substances among those workers. This study was performed with 238 workers, from June to November 2006, using univariate and multivariate analysis. The chance of not adopting precaution measures was 20.7 (95% CI: 5.68 - 75.14) times greater among drivers compared to physicians. No significant association was found between adopting universal precaution measures. The occupational accident rate was 20.6% (40.8% involving sharp-edged objects). The risk of physicians having an occupational accident was 2.7(95% CI: 1.05 - 7.09) times higher than that of drivers. The fact that a staff member had adequate knowledge about universal precaution measures was insufficient to foster compatible attitudes towards reducing the risk of transmitting infectious agents and causing occupational accidents.

Résistance aux diurétiques de l'anse en clinique [Resistance to loop diuretics in clinical practice]

Loop diuretics belong to the most common medications used in ambulatory and hospitalized patients, especially in situation of hypervolemia and chronic renal failure. Prolonged used of these agents in particular medical conditions can lead to attenuation of their diuretic effect, commonly known as "resistance" to diuretics. This article intends to review the main mechanisms of resistance to loop diuretic and the ways to counteract them in clinical practice.

Breathhold three-dimensional coronary magnetic resonance angiography using real-time navigator technology.

The acquisition duration of most three-dimensional (3D) coronary magnetic resonance angiography (MRA) techniques is considerably prolonged, thereby precluding breathholding as a mechanism to suppress respiratory motion artifacts. Splitting the acquired 3D volume into multiple subvolumes or slabs serves to shorten individual breathhold duration. Still, problems associated with misregistration due to inconsistent depths of expiration and diaphragmatic drift during sustained respiration remain to be resolved. We propose the combination of an ultrafast 3D coronary MRA imaging sequence with prospective real-time navigator technology, which allows correction of the measured volume position. 3D volume splitting using prospective real-time navigator technology, was successfully applied for 3D coronary MRA in five healthy individuals. An ultrafast 3D interleaved hybrid gradient-echoplanar imaging sequence, including T2Prep for contrast enhancement, was used with the navigator localized at the basal anterior wall of the left ventricle. A 9-cm-thick volume, with in-plane spatial resolution of 1.1 x 2.2 mm, was acquired during five breathholds of 15-sec duration each. Consistently, no evidence of misregistration was observed in the images. Extensive contiguous segments of the left anterior descending coronary artery (48 +/- 18 mm) and the right coronary artery (75 +/- 5 mm) could be visualized. This technique has the potential for screening for anomalous coronary arteries, making it well suited as part of a larger clinical MR examination. In addition, this technique may also be applied as a scout scan, which allows an accurate definition of imaging planes for subsequent high-resolution coronary MRA.
