Balancing the role of the dental school in teaching, research and patient care; including care for underserved areas

Inequalities within dentistry are common and are reflected in wide differences in the levels of oral health and the standard of care available both within and between countries and communities. Furthermore there are patients, particularly those with special treatment needs, who do not have the same access to dental services as the general public. The dental school should aim to recruit students from varied backgrounds into all areas covered by the oral healthcare team and to train students to treat the full spectrum of patients including those with special needs. It is essential, however, that the dental student achieves a high standard of clinical competence and this cannot be gained by treating only those patients with low expectations for care. Balancing these aspects of clinical education is difficult. Research is an important stimulus to better teaching and better clinical care. It is recognized that dental school staff should be active in research, teaching, clinical work and frequently administration. Maintaining a balance between the commitments to clinical care, teaching and research while also taking account of underserved areas in each of these categories is a difficult challenge but one that has to be met to a high degree in a successful, modern dental school.

Cavernous sinus thrombosis in a patient with facial myiasis

Cavernous sinus thrombosis is a severe encephalic complication of the cervicofacial infections that can lead to death if not treated in adequate time. Among the several etiologies related to the development of this infection, myiasis has not been reported, enforcing the importance of the report of a case of thrombosis of the cavernous sinus developed from a facial myiasis.

Schilbach-Rott/blepharofacioskeletal syndrome in a Brazilian patient

We report on a 4-year-old girl with blepharophimosis, a typical facial gestalt and skeletal abnormalities seen in the blepharofacioskeletal syndrome (BFSS). A comparative review with previous cases provides further evidence that BFSS and Schilbach-Rott syndrome (SRS) are the same condition. (C) 2008 Wiley-Liss, Inc.

The Genetics of Alzheimer`s Disease in Brazil: 10 Years of Analysis in a Unique Population

Alzheimer`s Disease (AD) is the most common type of dementia among the elderly, with devastating consequences for the patient, their relatives, and caregivers. More than 300 genetic polymorphisms have been involved with AD, demonstrating that this condition is polygenic and with a complex pattern of inheritance. This paper aims to report and compare the results of AD genetics studies in case-control and familial analysis performed in Brazil since our first publication, 10 years ago. They include the following genes/markers: Apolipoprotein E (APOE), 5-hidroxytryptamine transporter length polymorphic region (5-HTTLPR), brain-derived neurotrophin factor (BDNF), monoamine oxidase A (MAO-A), and two simple-sequence tandem repeat polymorphisms (DXS1047 and D10S1423). Previously unpublished data of the interleukin-1 alpha (IL-1 alpha) and interleukin-1 beta (IL-1 beta) genes are reported here briefly. Results from others Brazilian studies with AD patients are also reported at this short review. Four local families studied with various markers at the chromosome 21, 19, 14, and 1 are briefly reported for the first time. The importance of studying DNA samples from Brazil is highlighted because of the uniqueness of its population, which presents both intense ethnical miscegenation, mainly at the east coast, but also clusters with high inbreeding rates in rural areas at the countryside. We discuss the current stage of extending these studies using high-throughput methods of large-scale genotyping, such as single nucleotide polymorphism microarrays, associated with bioinformatics tools that allow the analysis of such extensive number of genetics variables, with different levels of penetrance. There is still a long way between the huge amount of data gathered so far and the actual application toward the full understanding of AD, but the final goal is to develop precise tools for diagnosis and prognosis, creating new strategies for better treatments based on genetic profile.

Iodide Transport Defect: Functional Characterization of a Novel Mutation in the Na(+)/I(-) Symporter 5 `-Untranslated Region in a Patient with Congenital Hypothyroidism

Context: Iodide transport defect (ITD) is an autosomal recessive disorder caused by impaired Na(+)/I(-) symporter (NIS)-mediated active iodide accumulation into thyroid follicular cells. Clinical manifestations comprise a variable degree of congenital hypothyroidism and goiter, and low to absent radioiodide uptake, as determined by thyroid scintigraphy. Hereditary molecular defects in NIS have been shown to cause ITD. Objective: Our objective was to perform molecular studies on NIS in a patient with congenital hypothyroidism presenting a clinical ITD phenotype. Design: The genomic DNA encoding NIS was sequenced, and an in vitro functional study of a newly identified NIS mutation was performed. Results: The analysis revealed the presence of an undescribed homozygous C to T transition at nucleotide -54 (-54C>T) located in the 5`-untranslated region in the NIS sequence. Functional studies in vitro demonstrated that the mutation was associated with a substantial decrease in iodide uptake when transfected into Cos-7 cells. The mutation severely impaired NIS protein expression, although NIS mRNA levels remained similar to those in cells transfected with wild-type NIS, suggesting a translational deficiency elicited by the mutation. Polysome profile analysis demonstrated reduced levels of polyribosomes-associated mutant NIS mRNA, consistent with reduced translation efficiency. Conclusions: We described a novel mutation in the 5`-untranslated region of the NIS gene in a newborn with congenital hypothyroidism bearing a clinical ITD phenotype. Functional evaluation of the molecular mechanism responsible for impaired NIS-mediated iodide concentration in thyroid cells indicated that the identified mutation reduces NIS translation efficiency with a subsequent decrease in protein expression and function.

Primary immunodeficiency diseases in Latin America: Proceedings of the Second Latin American Society for Immunodeficiencies (LASID) Advisory Board

Early diagnosis and appropriate therapy are essential for the best prognosis and quality of life in patients with primary immunodeficiency diseases (PIDDs). Experts from several Latin American countries have been meeting on a regular basis as part of an ongoing effort to improve the diagnosis and treatment of PIDD in this region. Three programmes are in development that will expand education and training and improve access to testing facilities throughout Latin America. These programmes are: an educational outreach programme (The L-Project); an immunology fellowship programme; and the establishment of a laboratory network to expand access to testing facilities. This report provides the status of these programmes based on the most recent discussions and describes the next steps toward full implementation of these programmes. (C) 2010 SEICAP.

Functional and morphologic evaluation of kidney proximal tubuli and correlation with renal allograft prognosis

P>Renal transplant patients with stable graft function and proximal tubular dysfunction (PTD) have an increased risk for chronic allograft nephropathy (CAN). In this study, we investigated the histologic pattern associated with PTD and its correlation with graft outcome. Forty-nine transplant patients with stable graft function were submitted to a biopsy. Simultaneously, urinary retinol-binding protein (uRBP) was measured and creatinine clearance was also determined. Banff`s score and semi-quantitative histologic analyses were performed to assess tubulointerstitial alterations. Patients were followed for 24.0 +/- 7.8 months. At biopsy time, mean serum creatinine was 1.43 +/- 0.33 mg/dl. Twelve patients (24.5%) had uRBP >= 1 mg/l, indicating PTD and 67% of biopsies had some degree of tubulointerstitial injury. At the end of the study period, 18 (36.7%) patients had lost renal function. uRBP levels were not associated with morphologic findings of interstitial fibrosis and tubular atrophy (IF/TA), interstitial fibrosis measured by Sirius red or tubulointerstitial damage. However, in multivariate analysis, the only variable associated with the loss of renal function was uRBP level >= 1 mg/l, determining a risk of 5.290 of loss of renal function (P = 0.003). Renal transplant patients who present PTD have functional alteration, which is not associated with morphologic alteration. This functional alteration is associated to progressive decrease in renal function.

Influence of hepatitis G virus (GB virus C) on the prognosis of HIV-infected women

This study was undertaken to evaluate the prevalence of GB virus C (GBV-C) viraemia and anti-E2 antibody, and to assess the effect of co-infection with GBV-C and HIV during a 10-year follow-up of a cohort of 248 HIV-infected women. Laboratory variables (mean and median CD4 counts, and HIV and GBV-C viral loads) and clinical parameters were investigated. At baseline, 115 women had past exposure to GBV-C: 57 (23%) were GBV-C RNA positive and 58 (23%) were anti-E2 positive. There was no statistical difference between the groups (GBV-C RNA + /anti-E2 -, GBV-C RNA - /anti-E2 + and GBV-C RNA - /anti-E2 -) regarding baseline CD4 counts or HIV viral loads (P = 0.360 and 0.713, respectively). Relative risk of death for the GBV-C RNA + /anti-E2 - group was 63% lower than that for the GBV-C RNA - /anti-E2 - group. Multivariate analysis demonstrated that only HIV loads >= 100,000 copies/mL and AIDS-defining illness during follow-up were associated with shorter survival after AIDS development. It is likely that antiretroviral therapy (ART) use in our cohort blurred a putative protective effect related to the presence of GBV-C RNA.

Omvårdnad vid Amyotrofisk lateral skleros : erfarenheter ur ett patient och anhörigperspektiv : En systematisk litteraturstudie

Amyotrofisk lateral skleros (ALS) är en fortskridande neurologiska sjukdom som ger den drabbade och de anhöriga mycket sorg och smärta. Syftet med föreliggande systematiska litteraturstudie var att utifrån aktuell vetenskaplig litteratur beskriva upplevelsen och behovet av omvårdnad som den sjuke i ALS och deras anhöriga behövde. Syftet var också att beskriva vilken typ av information och stöd som behövdes. De vetenskapliga artiklarna som ligger till grund för denna litteraturstudie har sökt på databaserna Elin@Dalarna och Blackwell Synergy. Artiklarna skulle vara publicerade mellan åren 2000-2007 och vara skrivna på engelska. Även manuella sökningar har gjorts. Resultatet visade att sjukvården hade ett stort ansvar att stötta, hjälpa och informera vid denna fortskridande neurologiska sjukdom. Det fanns behov av multiinriktad omvårdnad där många olika professioner ingick för att kunna ge patienterna den helhetsvård de behövde. Det framkom att anhöriga var de som hade den givna omvårdnadsrollen och att de hade ett behov av avlastning och information om sjukdomen, behandlingen och symtomen. Anhöriga upplevde sjukdomen som en stor börda och påverkade deras egna hälsa.

Clustering Lab value working with medical data

Data mining is a relatively new field of research that its objective is to acquire knowledge from large amounts of data. In medical and health care areas, due to regulations and due to the availability of computers, a large amount of data is becoming available [27]. On the one hand, practitioners are expected to use all this data in their work but, at the same time, such a large amount of data cannot be processed by humans in a short time to make diagnosis, prognosis and treatment schedules. A major objective of this thesis is to evaluate data mining tools in medical and health care applications to develop a tool that can help make rather accurate decisions. In this thesis, the goal is finding a pattern among patients who got pneumonia by clustering of lab data values which have been recorded every day. By this pattern we can generalize it to the patients who did not have been diagnosed by this disease whose lab values shows the same trend as pneumonia patients does. There are 10 tables which have been extracted from a big data base of a hospital in Jena for my work .In ICU (intensive care unit), COPRA system which is a patient management system has been used. All the tables and data stored in German Language database.

Palliativ omvårdnad : Ur ett patient-, närstående- och sjuksköterskeperspektiv

Syftet med denna systematiska litteraturstudie var att belysa patientens, närståendes samt sjuksköterskans upplevelser av palliativ vård, för att förbättra kvaliteten på omvårdnaden. Litteraturen söktes genom Högskolan Dalarnas databaser samt från tillgängliga e-tidskrifter. Till resultatdelen valdes 19 vetenskapliga artiklar i huvudsak från Europa, men även USA, skrivna på engelska. För att bedöma artiklarnas trovärdighet granskades dessa med hjälp av två granskningsmallar. I resultatet framgick att patienter upplevde det viktigt att behålla kontrollen över sitt liv trots sjukdomen. Genom sitt förhållningssätt kunde sjuksköterskan hjälpa patienten att bibehålla kontrollen och därmed bevara patientens livskvalitet. Närståendes känslomässiga reaktioner är många då en person i deras närhet drabbats av en livshotande sjukdom. De upplevde en sorg som börjar dagen efter diagnosen och fortsätter till långt efter patientens död. Även strukturen i närståendes dagliga liv förändrades, vilket ofta ledde till ensamhet. Sjuksköterskan hade en viktig uppgift att bygga upp en fungerande relation till patienten samt till närstående. Resultatet uppmärksammade även att ett bra samarbete i det palliativa teamet var betydelsefullt för patientens omvårdnad.

När Viljan inte finns att Leva : Suicidbenägenhet ur ett sjuksköterske- och patient perspektivEn systematisk litteraturstudie

Syftet med denna systematiska litteraturstudie var att undersöka vilka attityder sjuksköterskor hade gentemot suicidala patienter, vilka upplevelser patienter hade efter ett suicidförsök och hur de upplevde omvårdnaden de fick. I syftet ingick även att undersöka vilka kunskaper som en sjuksköterska behöver ha i mötet med suicidala personer. Sökning av artiklar har gjorts på databaserna Elin@Dalarna och Blackwell Synergy där sökorden attitudes, care, caring, nursing, nurse, suicide användes i olika kombinationer. Artiklarna skulle vara vetenskapliga, inte publicerade före 1997 och svara på syfte och frågeställning. För att säkerställa att kvalitén på artiklarna var god granskades de med hjälp av en granskningsmall. Sammanlagt ligger tretton artiklar till grund för resultatet i denna litteraturstudie. Resultatet visade att sjuksköterskor ofta hade en negativ attityd i arbetet med suicidpatienter, och sjuksköterskor på akuta avdelningar tenderade att vara mera negativa än de på psykiatriska avdelningar. Suicidpatientens personlighet hade betydelse för vilken attityd sjuksköterskan hade. Utbildning visade sig medföra en mera positiv inställning. Resultatet visade också att suicidpatienter ofta kände skam och känslor av misslyckande efter suicidförsök. Attityden sjuksköterskan visade påverkade patientens väg tillbaka. Det var viktigt för dem att bli sedd, lyssnad på och inte bli fördömd. Litteraturstudien visade att sjuksköterskor behöver kunskap och utbildning för att kunna möta denna patientgrupp för att ge bästa tänkbara omvårdnad i behandlingsarbetet.

Copingstrategier vid bröstcancer : Ur ett patient- och familjeperspektivEn systematisk litteraturstudie

Syftet med denna systematiska litteraturstudie var att undersöka vilka copingstrategier som kvinnor med bröstcancer, deras partners och barn använde. De vetenskapliga artiklar som ligger till grund för litteraturstudiens resultat söktes på databaserna Elin@Dalarna, Wiley InterScience och PubMed. De valda artiklarnas vetenskaplighet granskades med modifierade versioner av Willman, Stoltz & Bahtsevani och Forsberg & Wengströms granskningsmallar. Resultatet av denna litteraturstudie visade att det fanns olika copingstrategier som användes för hantering av kvinnors bröstcancer. Flera studiers forskningsresultat visade att de copingstrategier som kvinnor med bröstcancer använde var religion, acceptans, att ha ett positivt synsätt, förnekelse, emotionellt stöd och undvikande. Ytterligare copingstrategier som kvinnor använde var socialt stöd, aktiva copingstrategier, planering, att ventilera sig, humor och att sysselsätta sig med olika aktiviteter samt att ha ett oskäligt beteende. De copingstrategier som förekom hos kvinnornas partners var gruppstöd och kommunikation. Barn till kvinnor med bröstcancer använde sig av religion, kommunikation och stöd samt undvikande som copingstrategier.
