Local complications associated with labial salivary gland biopsy for diagnosis of Sjögren?s Syndrome : a retrospective cohort study
2019
Background To describe local or systemic complications related to the labial salivary glands biopsy (LSGB) used as diagnostic tool for the diagnosis of Sjogren's Syndrome (SS). Material and methods Clinical databases from a cohort of patients, who underwent LSGB with provisional clinical diagnosis of Sjogren's Syndrome, were retrospectively reviewed. Pain, assessed by registering the intake of analgesic drugs in the first week following the biopsy, and any further relevant clinical information regarding complications after biopsy were recorded. Results 50 patients received LSGB. 10 of them (9 women and 1 man) showed histopathological findings compatible with SS. Ten patient (20%) receiving …
The effective and safe method for preventing and treating bacteria-induced dental diseases by herbal plants and a recombinant peptide
2020
Background This study was conducted aimed at evaluating the antibacterial property of the recombinant peptide of bacteriocin entrocin P (EnP), the essential oil of Cuminum cyminum, and the extract of Ferulago angulata on some oral pathogens. Besides, the cytotoxicity of EnP was evaluated. Material and methods The antimicrobial property was tested on streptococcus mutans (ATCC 35668), streptococcus salivarius (ATCC 9222), streptococcus oralis (ATCC 35037), and Enterococcus faecalis (ATCC 29212), using the microbroth dilution method. The 0.2% Chlorhexidin (CHX) mouthwash was used as the control group. Besides, the cytotoxicity analysis was done on gingival fibroblasts by the MTT colorimetric …
Red propolis hydroalcoholic extract inhibits the formation of Candida albicans biofilms on denture surface
2020
Background To evaluate the antifungal activity of the red propolis hydroalcoholic extract (RPHE) against Candida albicans biofilms. Material and Methods The minimum inhibitory and fungicidal concentrations (MIC and MFC) of the RPHE were determined by the microdilution technique. C. albicans biofilms were formed on the surface of resin specimens preconditioned with artificial saliva (1h). The specimens (N=48) were equally divided according to the four solutions used for anti-biofilm evaluation (n=12 per group). After overnight incubation, biofilms were daily exposed (2x/day for 15 min) along 3 days with 3% RPHE, 0.12% chlorhexidine (CHX), 50,000 IU/mL nystatin (NYS) or saline (0.9% NaCl). Bi…
Comparison of growth, acidification and productivity of pure and mixed cultures of Streptococcus salivarius subsp. thermophilus 404 and Lactobacillus…
1994
International audience; Pure and mixed controlled-pH batch cultures of Streptococcus salivarius subsp. thermophilus 404 and Lactobacillus delbrueckii subsp. bulgaricus 398 have been conducted. The characteristics of growth and acidification and the productivity of the cultures were compared. During the mixed cultures, the growth characteristics revealed a pronounced stimulation of S. thermophilus whereas L. bulgaricus metabolism was not significantly improved. The final total population was 1.4 to 4.9 higher than in pure cultures. The acidification characteristics were not enhanced by the mixed culture conditions. The productivity of mixed cultures was 1.7 to 2.4 times higher as compared to…
How does a newly born mouse get to the nipple? odor substrates eliciting first nipple grasping and sucking responses
2012
It is a mammalian female strategy to emit odor cues and signals that direct their inexperienced newborns to the nipple, and optimize their initial sucking success and, hence, viability. Here, natural odorous substrates that contribute to nipple grasping were investigated in mice, a species that has not been much scrutinized on this topic. The response of pups toward the nipples of lactating females (LF) versus nonlactating females (NLF) were first assessed right after watched birth, before and after the first suckling experience, and at 1 day old, after more extended suckling experience. It appeared that only nipples of LF induced grasping at these early ages, leading to take NLF as the bas…
Is there scientific evidence of the mouthwashes effectiveness in reducing viral load in Covid-19? A systematic review.
2020
Background The aim of this research is to verify whether there is evidence in the literature regarding the decrease in viral load present in saliva after using three types of mouthwashes. Material and methods Clinical and/or in vitro experimental studies that have used mouthwashes as a form of intervention to reduce the viral load in saliva were included. Combinations of words and appropriate truncations were adapted for each of the seven selected electronic bases including grey literature. Results The selection of articles was carried out in two phases by two independent reviewers. After removing duplicate articles, 1245 references were maintained, and 2 articles were included in the Syste…
Fibromialgia: relación entre el estrés crónico, depresión, procesos inflamatorios y dolor.
2015
Por el término Fibromialgia (FM), asumimos un trastorno de etiología no conocida hasta el momento, aparentemente crónico, que se caracteriza por dolor muscular y articular generalizado incluyendo hipersensibilidad a numerosos estímulos como la presión, el frio o el calor. En la actualidad, la propia definición del cuadro, sus criterios diagnósticos y su etiopatogenia siguen siendo causa de debate. En los últimos años han ido apareciendo en la literatura numerosas hipótesis sobre el proceso de desarrollo de la FM que, aunque siguen aparentemente un patrón opuesto no se puede descartar que sean complementarias y se retroalimenten. En nuestro estudio nos hemos centrado en las hipótesis basadas…
Efecto de la radioterapia en glándulas salivales accesorias.
2005
El objetivo de este trabajo es estudiar las alteraciones que las radiacionesionizantes producen sobre las glándulas salivales accesorias labiales. Ennuestro estudio se seleccionaron sujetos diagnosticados de un tumor malignode cabeza y cuello que iban a recibir radioterapia dentro de su tratamiento,incluyendo los labios dentro del campo de irradiación. Se evaluó la secreciónsalival y las alteraciones morfológicas de las glándulas en el momento deldiagnóstico y a los tres meses de finalizar el tratamiento radioterápico.Se incluyeron en el estudio 17 sujetos. Antes de la radioterapia lasecreción salival media fue de 0,21 ml/m; en cuatro de los sujetos existía atrofiaglandular leve antes de di…
Acute stress and working memory in older people.
2015
Several studies have shown that acute stress affects working memory (WM) in young adults, but the effect in older people is understudied. As observed in other types of memory, older people may be less sensitive to acute effects of stress on WM. We performed two independent studies with healthy older men and women (from 55 to 77 years old) to investigate the effects of acute stress (Trier Social Stress Test; TSST) and cortisol on WM. In study 1 (n = 63), after the TSST women (but not men) improved their performance on Digit Span Forward (a measure of the memory span component of WM) but not on Digit Span Backward (a measure of both memory span and the executive component of WM). Furthermore,…
Adenoma de células basales de glándula parótida: Caso clínico y revisión de la literatura
2006
El adenoma de células basales de las glándulas salivares es un tipo de adenoma monomorfo de aparición infrecuente. La localización más habitual es la superficie de la glándula parótida. Suele debutar clínicamente como una masa firme y desplazable de crecimiento lento. Histológicamente se observan células isomórficas formando nidos y trabéculas interanastomosadas, con una membrana basal prominente, separadas por un estroma laxo e hialino y ausencia de estroma mixoide o condroide. A diferencia del adenoma pleomorfo, tiende a la multicentricidad y su tasa de recurrencia después de la extirpación quirúrgica es alta. Debido a sus implicaciones pronósticas, el diagnóstico diferencial con el adeno…
