Taktil beröring/massage : En systematisk litteraturstudie om effekten och upplevelsen av taktil beröring/massage vid oro/ångest hos cancerpatienter.

Syftet med denna systematiska litteraturstudie var att granska och lyfta fram vetenskapliga artiklar om beröringens/massagens upplevelser och effekter vid oro/ångest hos cancerpatienter. Artiklar har sökts i databaserna Cinahl, Medline, SveMed +, Pubmed och Elin@Dalarna och artiklarnas inklusionskriterier var att den taktila beröringen/massagen var av kroppslig kontakt, och de skulle rikta sig till vuxna cancerpatienter som upplevde symtom som oro och ångest. Artiklarna fick inte var äldre än 10 år. Resultatet påvisade att oro/ångest kunde minskas signifikant med massage/beröring hos cancerpatienter. I studier där upplevda effekter undersöktes visades det att vid beröring/massage hos cancerpatienter minskades oro/ångest och upplevelsen beskrevs som att spänningar försvann och att en avslappnande känsla infann sig. Beröring/massage gav inte några negativa påföljder och är en säker, effektiv behandlingskomplement till vanlig medicinsk behandling för förbättring av stressade symtom hos cancerpatienter.

Sjuksköterskans omvårdnadsåtgärder för att lindra patientens oro inför operation.

Syftet med denna litteraturstudie var att undersöka vilka emotionella omvårdnadsbehov patienterna hade innan operation och hur sjuksköterskan på bästa sätt kunde lindra dem. Metoden var en litteraturstudie baserad på vetenskapliga artiklar med dels en kvalitativ ansats (n= 5) och dels en kvantitativ (n= 10). Artikelsökningarna gjordes via sökmotorn ELIN och databaserna CINAHL och PubMED. Artiklarna var etiskt godkända samt publicerade mellan 2000-2010 och skrivna på engelska. De granskades med hjälp av granskningsmallar. Resultaten i studien visade att de emotionella behov som fanns var att lindra rädsla och känslan av övergivenhet. Resultaten visade att sjuksköterskan, kunde lindra dessa emotionella behov genom information, ett gott bemötande, att låta patienterna lyssna på musik, se på film eller video samt ge essentiella oljor.

Oro-genital lichen planus: Report of two cases

Lichen planus is a common mucocutaneous disease. However, lichen planus with concomitant oral and genital involvement is a rare condition that requires multidisciplinary intervention for appropriate diagnosis. In this study, we reported two cases of oro-genital lichen planus in a man and a woman. Analyses of oral and genital lesions were clinically and histopathologically compatible with lichen planus. This description highlights the importance of patients presenting oral lichen planus be routinely required to undergo further medical examination in order to investigate putative genital mucosal involvement. These lesions have the potential to progress to neoplasia. Therefore, medical and dentistry professionals should be aware of this condition. (c) 2007 Elsevier B.V. All fights reserved.

Development, characterization and clinical use of a biodegradable composite scaffold for bone engineering in oro-maxillo-facial surgery

We have developed a biodegradable composite scaffold for bone tissue engineering applications with a pore size and interconnecting macroporosity similar to those of human trabecular bone. The scaffold is fabricated by a process of particle leaching and phase inversion from poly(lactide-co-glycolide) (PLGA) and two calcium phosphate (CaP) phases both of which are resorbable by osteoclasts; the first a particulate within the polymer structure and the second a thin ubiquitous coating. The 3-5 mu m thick osteoconductive surface CaP abrogates the putative foreign body giant cell response to the underlying polymer, while the internal CaP phase provides dimensional stability in an otherwise highly compliant structure. The scaffold may be used as a biomaterial alone, as a carrier for cells or a three-phase drug delivery device. Due to the highly interconnected macroporosity ranging from 81% to 91%, with macropores of 0.8 similar to 1.8 mm, and an ability to wick up blood, the scaffold acts as both a clot-retention device and an osteoconductive support for host bone growth. As a cell delivery vehicle, the scaffold can be first seeded with human mesenchymal cells which can then contribute to bone formation in orthotopic implantation sites, as we show in immune-compromised animal hosts. We have also employed this scaffold in both lithomorph and particulate forms in human patients to maintain alveolar bone height following tooth extraction, and augment alveolar bone height through standard sinus lift approaches. We provide a clinical case report of both of these applications; and we show that the scaffold served to regenerate sufficient bone tissue in the wound site to provide a sound foundation for dental implant placement. At the time of writing, such implants have been in occlusal function for periods of up to 3 years in sites regenerated through the use of the scaffold.

Circulando en el laberinto: la economía política de la salida del patrón oro en la Argentina (1929-1933)

Este artículo es la pequeña, pero crucial historia de un régimen cambiario-monetario en tránsito durante cuatro años, que culminó en 1933 con la desaparición definitiva del patrón oro en la Argentina. Ese proceso se caracterizó por decisiones tomadas en coyunturas críticas frente a las cuales las autoridades de gobierno no podían andar pausadamente, ante las cuales no tenían un arsenal analítico, ni certezas técnicas, ni convicciones políticas. El objetivo de este estudio es analizar esas “decisiones” a lo largo de siete hitos, siendo el primero el shock externo de 1929 y el último el envío al Congreso de una ley para la creación del banco central y un régimen de control de cambios caracterizado por tipos de cambio múltiples. El nuevo régimen implícito en ese reordenamiento de la economía argentina habría de perdurar, con sus idas y venidas, por al menos un cuarto de siglo.

Isolation and molecular identification of Fusobacterium nucleatum from Nigerian patients with oro-facial infections.

Fusobacterium nucleatum is one of the most common anaerobic bacteria present in the oral cavity and is often isolated from infections involving other body sites. To characterise F. nucleatum strains from patients attending a teaching hospital in Nigeria in order to provide information on the methods for accurate identification of anaerobes in clinical specimen. Fusobacterium nucleatum specie from 50 patients presenting with oro-facial infections were studied by culture on Fusobacterium selective agar and fastidious anaerobe agar. The isolates were characterised based on colonial morphology, microscopy, lipase production, susceptibility to kanamycin and colistin and resistance to vancomycin. Biochemical tests were performed using a commercial test kit. The identity of the isolates was confirmed based on molecular characterization performed using polymerase chain reaction (PCR) analysis. Forty-eight (96%) F. nucleatum isolates were obtained from the 50 patients by culture and all the isolates were identified by colonial appearance and microscopy based on their unique spindle shape with tapered ends. Only 26 (54.2%) of the 48 isolates were identified by commercial API 20A test kit while PCR confirmed the identity of all the isolates. Anaerobes are involved in human infections and their study is quite cumbersome due to tedious nature and high cost of the techniques involved. Cultural method is reliable in the isolation and identification of F. nucleatum species. PCR is a rapid and simple method that can complement the phenotypic identification of anaerobes and would assist in their full identification.
