Pronóstico y tratamiento de la boca seca. Revisión sistemática

No existen protocolos claramente establecidos para el tratamiento de la boca seca. El objetivo de este trabajo es realizar una revisión sistemática de la literatura médica de los últimos 10 años. Hemos utilizado las palabras: «dry mouth», «prognosis», «treatment» y «dentistry». En una primera búsqueda hemos encontrado 1.450 entradas. Con la restricción «clinical trials OR randomized controlled trial OR systemic reviews» se han reducido a 522, de las que 145 eran metaanálisis y revisiones sistemáticas. Se han eliminado las que no eran pertinentes al tema y han quedado reducidas a 53. Posteriormente se descartaron 24 (8 no pertinentes, 7 revisiones y 9 opiniones personales). De los 29 artículos analizados, 15 son ensayos clínicos controlados, 2 ensayos no controlados, 4 estudios observacionales, 2 revisiones sistemáticas y 5 revisiones. Los enfermos mejor estudiados son los pacientes con síndrome de Sjögren y los pacientes irradiados. El tratamiento se centra en el etiológico, preventivo, sintomático, de estimulación salival local y sistémicos. Podemos concluir que el tratamiento debe ser individualizado, pudiéndose aplicar sustitutos salivales y diferentes técnicas de estimulación mecánica. There are no clearly established protocols for the treatment of dry mouth. The aim of this paper is a systematic review of the literature of the past 10 years using the words «dry mouth», «prognosis», «treatment» and «dentistry». The initial search found 1,450 entries and within the restriction «clinical trials OR randomized controlled trial OR systemic reviews» it has been reduced to 522, which 145 were meta-analysis and systematic reviews. Papers not relevant to the issue were removed reducing the entries to 53. Twenty-four were dismissed (8 irrelevant, 7 reviews without adequate information and 9 personal opinions). Of the 29 items tested, 15 were controlled trials, 2 uncontrolled trials, 4 observational studies, 2 systematic reviews and 5 non systematic reviews. The most studied patients were Sjögren's syndrome and the irradiated patients. Treatments are focused on the etiology, prevention, symptomatic, local salivary stimulation and systemic treatments. It can be concluded that treatment must be individualized, salivary substitutes and mechanical stimulation techniques can be applied.

Síndrome de boca ardiente: claves diagnósticas y terapéuticas

El síndrome de boca ardiente (SBA) se conoce también como boca escaldada, ardor bucal, glosodinia, glosopirosis, estomatodinia, estomatopirosis o disestesia oral. Se caracteriza por dolor o sensación de ardor, escozor o picazón, a veces aspereza, sobre todo en la lengua, paladar duro y labio inferior, en ausencia de datos clínicos o de laboratorio que justifiquen estos síntomas. Puede acompañarse de disgeusia (trastornos del gusto) y de xerostomía (boca seca), constituyendo la tríada clásica. Su etiología, poco precisa, es multifactorial. La evolución del cuadro tiende a ser crónica, alternando períodos de exacerbación y mejoría durante meses o años. Es más frecuente en mujeres perimenopáusicas o posmenopáusicas. Los episodios de SBA aparecen de forma espontánea y presentan un abanico variable en la gravedad de los síntomas. Mientras algunos pacientes refieren malestar leve o moderado, otros manifiestan dolor insoportable. Los síntomas suelen ser menos intensos...

Boca seca y boca ardiente

La saliva es esencial para mantener la salud oral. El 99% de su composición es agua. El desencadenante más común de boca seca es la toma de medicamentos, generalmente acompañada de escasa ingesta de líquidos. Entre sus complicaciones cabe destacar xerostomía, disgeusia y ardor bucal, entre otras. Estos síntomas son tríada frecuente del síndrome de boca ardiente (SBA). Su etiología es imprecisa y multifactorial, sin datos clínicos o de laboratorio específicos. En su patogenia intervienen factores locales, sistémicos y psicológicos. Es común la asociación de hábitos parafuncionales evidentes, dentarios y linguales, con repercusión en tejidos duros (desgaste, ATM) y blandos (lesiones facticias, irritación de papilas linguales). Afecta más a mujeres en edad perimenopáusica, en proporción hasta 7:1 respecto a los hombres. A menudo se asocian ansiedad o depresión. En este trabajo se propone la parafunción deglutoria como parte integrante del síndrome.

Disparities in work, risk and health between immigrants and native-born Spaniards

We analyse the impact of working and contractual conditions, particularly exposure to job risks, on the probability of acquiring a permanent disability, controlling for other personal and firm characteristics. We postulate a model in which this impact is mediated by the choice of occupation, with a level of risk associated with it. We assume this choice is endogenous, and that it depends on preferences and opportunities in the labour market, both of which may differ between immigrants and natives. To test this hypothesis we apply a bivariate probit model to data for 2006 from the Continuous Sample of Working Lives provided by the Spanish Social Security system, containing records for over a million workers. We find that risk exposure increases the probability of permanent disability arising from any cause - by almost 5%.

Effectiveness of substituting cyclosporin A with tacrolimus in reducing gingival overgrowth in renal transplant patients

Objectives: This study aims to evaluate the effectiveness of periodontal therapy combined with tacrolimus in the suppression of gingival overgrowth (GO) and the effect on GO of changing from cyclosporin A to tacrolimus. Patients and Methods: Sixteen renal transplant patients, averaging 52 years of age, whose kidney function was stable and were receiving treatment with cyclosporin A, were randomly assigned to one of two groups. In the experimental group, patients were instructed in oral hygiene and underwent periodontal treatment, whereas in the control group, only oral hygiene instructions were given. After the first visit and the change of medication from cyclosporine to tacrolimus in both groups, periodic clinical revisions were carried out for 3 months in order to assess the evolution of GO. Results: All patients showed a progressive decrease in GO. There were no statistically significant differences between the two groups (p>0.05). A greater decrease in GO occurred within the first month after changing the medication. Conclusions: No improved effectiveness in reducing GO was observed for periodontal therapy in combination with tacrolimus. Tacrolimus is an alternative to cyclosporine when attempting to avoid GO in patients with kidney transplants

Systematic review protocol to define classical IgE-associated diseases from birth to adolescence: the MeDALL study

BACKGROUND: Classical disease phenotypes are mainly based on descriptions of symptoms and the hypothesis that a given pattern of symptoms provides a diagnosis. With refined technologies there is growing evidence that disease expression in patients is much more diverse and subtypes need to be defined to allow a better targeted treatment. One of the aims of the Mechanisms of the Development of Allergy Project (MeDALL,FP7) is to re-define the classical phenotypes of IgE-associated allergic diseases from birth to adolescence, by consensus among experts using a systematic review of the literature and identify possible gaps in research for new disease markers. This paper describes the methods to be used for the systematic review of the classical IgE-associated phenotypes applicable in general to other systematic reviews also addressing phenotype definitions based on evidence. METHODS/DESIGN: Eligible papers were identified by PubMed search (complete database through April 2011). This search yielded 12,043 citations. The review includes intervention studies (randomized and clinical controlled trials) and observational studies (cohort studies including birth cohorts, case-control studies) as well as case series. Systematic and non-systematic reviews, guidelines, position papers and editorials are not excluded but dealt with separately. Two independent reviewers in parallel conducted consecutive title and abstract filtering scans. For publications where title and abstract fulfilled the inclusion criteria the full text was assessed. In the final step, two independent reviewers abstracted data using a pre-designed data extraction form with disagreements resolved by discussion among investigators. DISCUSSION: The systematic review protocol described here allows to generate broad,multi-phenotype reviews and consensus phenotype definitions. The in-depth analysis of the existing literature on the classification of IgE-associated allergic diseases through such a systematic review will 1) provide relevant information on the current epidemiologic definitions of allergic diseases, 2) address heterogeneity and interrelationships and 3) identify gaps in knowledge.

Systems medicine and integrated care to combat chronic noncommunicable diseases

We propose an innovative, integrated, cost-effective health system to combat major non-communicable diseases (NCDs), including cardiovascular, chronic respiratory, metabolic, rheumatologic and neurologic disorders and cancers, which together are the predominant health problem of the 21st century. This proposed holistic strategy involves comprehensive patient-centered integrated care and multi-scale, multi-modal and multi-level systems approaches to tackle NCDs as a common group of diseases. Rather than studying each disease individually, it will take into account their intertwined gene-environment, socio-economic interactions and co-morbidities that lead to individual-specific complex phenotypes. It will implement a road map for predictive, preventive, personalized and participatory (P4) medicine based on a robust and extensive knowledge management infrastructure that contains individual patient information. It will be supported by strategic partnerships involving all stakeholders, including general practitioners associated with patient-centered care. This systems medicine strategy, which will take a holistic approach to disease, is designed to allow the results to be used globally, taking into account the needs and specificities of local economies and health systems.

The reappearance of a forgotten disease in the oral cavity: syphilis

Syphilis is a sexually transmitted disease (STD) produced by Treponema pallidum, which mainly affects humans and is able to invade practically any organ in the body. Its infection facilitates the transmission of other STDs. Since the end of the last decade, successive outbreaks of syphilis have been reported in most western European countries. Like other STDs, syphilis is a notifiable disease in the European Union. In Spain, epidemiological information is obtained nationwide via the country"s system for recording notifiable diseases (Spanish acronym EDO) and the national microbiological information system (Spanish acronym SIM), which compiles information from a network of 46 sentinel laboratories in twelve Spanish regions. The STDs that are epidemiologically controlled are gonococcal infection, syphilis, and congenital syphilis. The incidence of each of these diseases is recorded weekly. The information compiled indicates an increase in the cases of syphilis and gonococcal infection in Spain in recent years. According to the EDO, in 1999, the number of cases of syphilis per 100,000 inhabitants was recorded to be 1.69, which has risen to 4.38 in 2007. In this article, we review the reappearance and the evolution of this infectious disease in eight European countries, and alert dentists to the importance of a) diagnosing sexuallytransmitted diseases and b) notifying the centres that control them

Diabetes mellitus, periapical inflammation and endodontic treatment outcome

The possible connection between chronic oral inflammatory processes, such as apical periodontitis and periodontal disease (PD), and systemic health is one of the most interesting aspects faced by the medical and dental scientific community. Chronic apical periodontitis shares important characteristics with PD: 1) both are chronic infections of the oral cavity, 2) the Gram-negative anaerobic microbiota found in both diseases is comparable, and 3) in both infectious processes increased local levels of inflammatory mediators may have an impact on systemic levels. One of the systemic disorders linked to PD is diabetes mellitus (DM); is therefore plausible to assume that chronic apical periodontitis and endodontic treatment are also associated with DM. The status of knowledge regarding the relationship between DM and endodontics is reviewed. Upon review, we conclude that there are data in the literature that associate DM with a higher prevalence of periapical lesions, greater size of the osteolityc lesions, greater likelihood of asymptomatic infections and worse prognosis for root filled teeth. The results of some studies suggest that periapical disease may contribute to diabetic metabolic dyscontrol

Effect of cocoa powder in the prevention of cardiovascular disease: biological, consumption and inflammatory biomarkers. A metabolomic approach

Numerous health benefits have been attributed to cocoa and its derived products in the last decade including antioxidant, anti-platelet and positive effects on lipid metabolism and vascular function. Inflammation plays a key role in the initiation and progression of atherosclerosis. However, cocoa feeding trials focused on inflammation are still rare and the results yielded are controversial. Health effects derived from cocoa consumption have been partly attributed to its polyphenol content, in particular of flavanols. Bioavailability is a key issue for cocoa polyphenols in order to be able to exert their biological activities. In the case of flavanols, bioavailability is strongly influenced by several factors, such as their degree of polymerization and the food matrix in which the polyphenols are delivered. Furthermore, gut has become an active site for the metabolism of procyanidins (oligomeric and polymeric flavanols). Estimation of polyphenol consumption or exposure is also a very challenging task in Food and Nutrition Science in order to correlate the intake of phytochemicals with in vivo health effects. In the area of nutrition, modern analytical techniques based on mass spectrometry are leading to considerable advances in targeted metabolite analysis and particularly in Metabolomics or global metabolite analysis. In this chapter we have summarized the most relevant results of our recent research on the bioavailability of cocoa polyphenols in humans and the effect of the matrix in which cocoa polyphenols are delivered considering both targeted analysis and a metabolomic approach. Furthermore, we have also summarized the effect of long-term consumption of cocoa powder in patients at high risk of cardiovascular disease (CVD) on the inflammatory biomarkers of atherosclerosis.

CX3CR1 is a modifying gene of survival and progression in Amyotrophic Lateral Sclerosis

The objective of this study was to investigate the association of functional variants of the human CX3CR1 gene (Fractalkine receptor) with the risk of Amyotrophic Lateral Sclerosis disease (ALS), the survival and the progression rate of the disease symptoms in a Spanish ALS cohort. 187 ALS patients (142sporadic [sALS] and 45 familial) and 378 controls were recruited. We investigated CX3CR1 V249I (rs3732379) and T280M (rs3732378) genotypes and their haplotypes as predictors of survival, the progression rate of the symptoms (as measured by ALSFRS-R and FVC decline) and the risk of suffering ALS disease. The results indicated that sALS patients with CX3CR1 249I/I or 249V/I genotypes presented a shorter survival time (42.21±4.82) than patients with 249V/V genotype (67.48±7.28; diff=-25.27 months 95%CI [-42.09,-8.45]; p=0.003). The survival time was shorter in sALS patients with spinal topography and CX3CR1 249I alleles (diff -29.78 months; 95%CI [-49.42,-10.14]; p=0.003). The same effects were also observed in the spinal sALS patients with 249I-280M haplotype (diff=-27.23 months; 95%CI [-49.83,-4.64]; p=0.018). In the sALS group, the CX3CR1 249I variant was associated with a faster progression of the disease symptoms (OR= 2.32; 95IC%[1.24, 4.33]; p=0.007). There was no evidence for association of these two CX3CR1 variants with ALS disease risk. The association evidenced herein is clinically relevant and indicates that CX3CR1 could be a disease-modifying gene in sALS. The progression rate of the disease"s symptoms and the survival time is affected in patients with one or two copies of the CX3CR1 249I allele. The CX3CR1 is the most potent ALS survival genetic factor reported to date. These results reinforce the role of the immune system in ALS pathogenesis.

Característiques epidemiològiques i topogràfiques de les lesions patides per un col•lectiu d’esportistes d’alt rendiment durant un període de 45 mesos

En els darrers anys s’han publicat diversos articles que descriuen l’epidemiologia de les malalties i lesions patides per persones que practiquen diferents esports. Aquestes investigacions s’han fet a partir de les dades reco· llides durant períodes d’entrenament de diversa durada o bé durant unes competicions concretes, com poden ser uns Jocs Olímpics. L’objectiu del present estudi va ser el de recollir i analitzar les dades epidemiològiques de les lesions patides per una població d’esportistes del nostre país, durant un període de temps determinat que inclou tant el temps d’entrenament com el de competició. La informació va ser recollida en el servei mèdic d’un centre d’entrenament esportiu, a partir de les dades de les visites mèdiques recollides en l’historial clínic de cada espor· tista. Es van revisar 16.925 visites mèdiques, realitzades en 45 mesos, d’esportistes d’ambdós gèneres i de 29 esports diferents. Les variables que es van analitzar van ser el tipus de lesió, les circumstàncies de producció de la lesió i la topografia de la lesió.Es va veure que el 90 % de totes les lesions es van produir durant l’entrenament. Les més freqüents van ser les agudes (75 %). Les parts del cos més afectades van ser el genoll (17 %), el turmell (12 %), el peu (11%), la cintura escapular (10 %) i la regió lumbar (10 %).

Ellis-Van Creveld Syndrome. Case report and literature review

Ellis-van Creveld syndrome is a genetic disorder that was first described by Richard Ellis and Simon van Creveld in 1940. The four principal characteristics are chondrodysplasia, polydactyly, ectodermal dysplasia and congenital heart defects. The orofacial manifestations include multiple gingivolabial musculofibrous fraenula, dental anomalies, hypodontia and malocclusion. The disease can be diagnosed at any age, even during pregnancy. The differentiation should be made between Jeune syndrome and other orofaciodigital syndromes
