Treatment options for mandibular canine transmigration - a case series based on dental literature.

The present case series, based on dental literature, aimed to identify factors that influence the final treatment decision for patients affected by mandibular canine transmigration using individual data from case reports in the literature. The protocol used for data synthesis was prepared following the Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines. An online search was conducted and included studies published up until September of 2019 (MEDLINE, Google Scholar, Scielo, and Conricyt). A chi squared test was used to evaluate associations between the treatment choice and gender, age, Mupparapu classification, and the presence of oral pathologies or dental anomalies (p < 0.05). A multinomial logistic regression was used to evaluate the individual case report data to determine the effect of the explanatory variables for treatment selection. Seventy-six papers fulfilled the inclusion criteria. Surgical removal (46.71%) and radiographic monitoring (38.16%) were the most common treatments reported. Age, Muppararu classification, and the presence of oral pathologies were significantly associated with the treatment option (p < 0.05). In conclusion, surgical removal and radiographic monitoring are the most frequently reported treatments for mandibular canine transmigration. Age, Mupparapu type, presence of oral pathologies, and qualitative aspects such as emotional reasons are relevant for the decision regarding treatment approach.

Periodontitis and Alzheimer´s disease.

BACKGROUND: Alzheimer's disease (AD), the main cause of dementia in the adult population, is characterized by a progressive loss of cognitive function. It is considered that neuroinflammation plays a fundamental role in its onset and progression. The bacteria present in the disbiotic microbiome generated during the course of periodontitis (PE) are capable of inducing a systemic inflammatory response, exacerbating the production of proinflammatory mediators that have the potential to spread to the systemic circulation. MATERIAL AND METHODS: A literature review was made using the databases Scielo, PubMed, EBSCO and key words "Alzheimer disease", "Periodontitis", "Neurodegeneration", "Inflammation mediators", "Elderly". RESULTS: Several hypotheses point to similar pathophysiological pathways in the establishment of AD and PE, sharing cellular and molecular proinflammatory characteristics. In periodontitis, locally produced cytokines and pro-inflammatory products spread from the ulcerated periodontal pocket into the systemic circulation, or around the trigeminal nerve terminals, which allows the passage of bacteria or their products to the brain. This fact leads to the formation of plaques of amyloid peptide and intraneuronal neurofibrillar tangles (NFTs) that activate the glial cells producing a significant increase in proinflammatory cytokines in the affected regions that lead to a loss of neuronal synapses and neurodegeneration, contributing to the progression of AD. CONCLUSIONS: This review of the literature contributes to the understanding of the pathological pathways shared by both diseases such as oxidative damage and inflammation. There is not enough evidence to determine an association between this two pathologies, so it is considered necessary to conduct studies for determine if periodontitis is capable of inducing or exacerbating the neuroinflammation that will trigger AD.

Caracterización de indicadores de detección de glaucoma con los equipos OCT Spectralis y campímetro Humphrey II en pacientes altos miopes y altos miopes glaucomatosos del Hospital Clínico Universidad de Chile / Characterization of glaucoma detection indicators with OCT Spectralis equipment and Humphrey II campimeter in patients with high myopia and high myopia glaucomatous at the Hospital Clínico Universidad de Chile

Purpose: Characterize and describe glaucoma index parameters of the results of visual exams, Optical Coherence Tomography and Visual Field, in high myopic subjects with and without the pathology. Method: Cross sectional and observational study of 39 eyes, 15 high myopic with glaucoma y 24 high myopic without it. Visual Field (VF) were performed, where the global index between both groups were analyzed; Mean Deviation (MD), Model Standard Deviation (MSD) and Visual Field Index (VFI), beside Optical Coherence Tomography (OCT), in which the thickness of the ganglion cells layer (GCL) inside 3 central mm was compared. Results: The results were satisfactory, demonstrating different characteristics between the high myopic group with glaucoma and without it, both in VF and OCT exams. It was obtained in the VF analysis difference in average MD of -4,92 dB + 3,71 (p<0,05); difference in average DSM of 2,01 dB + 2,85 (p>0,05) and VFI with Friedman Test 10,29 (p>0,05). The statistical OCT analysis, when comparing GCL, observed that the Temporary sector (T) had a statistically significant decrease (p<0,05). Conclusions: To continue studies in this investigative line, can expand the knowledge in this area, mainly in the study of the GCL. (AU)

Assessing dynamic postural control during exergaming in older adults: A probabilistic approach.

Digital games controlled by body movements (exergames) have been proposed as a way to improve postural control among older adults. Exergames are meant to be played at home in an unsupervised way. However, only few studies have investigated the effect of unsupervised home-exergaming on postural control. Moreover, suitable methods to dynamically assess postural control during exergaming are still scarce. Dynamic postural control (DPC) assessment could be used to provide both meaningful feedback and automatic adjustment of exergame difficulty. These features could potentially foster unsupervised exergaming at home and improve the effectiveness of exergames as tools to improve balance control. The main aim of this study is to investigate the effect of six weeks of unsupervised home-exergaming on DPC as assessed by a recently developed probabilistic model. High probability values suggest 'deteriorated' postural control, whereas low probability values suggest 'good' postural control. In a pilot study, ten healthy older adults (average 77.9, SD 7.2 years) played an ice-skating exergame at home half an hour per day, three times a week during six weeks. The intervention effect on DPC was assessed using exergaming trials recorded by Kinect at baseline and every other week. Visualization of the results suggests that the probabilistic model is suitable for real-time DPC assessment. Moreover, linear mixed model analysis and parametric bootstrapping suggest a significant intervention effect on DPC. In conclusion, these results suggest that unsupervised exergaming for improving DPC among older adults is indeed feasible and that probabilistic models could be a new approach to assess DPC.

Incidence and risk factors for post-traumatic stress disorder in a population affected by a severe flood.

OBJECTIVES: We aimed to study the risk of developing post-traumatic stress disorder (PTSD) symptoms in people who resided in an affected area by an extremely severe flood, and sociodemographic risk factors associated with this condition. STUDY DESIGN: A geographic information system (GIS) was used to distribute the rainfall data. A case-control study was developed to study the relationship between PTSD and sociodemographic risk factors. METHODS: To delineate the areas affected by the flood and the intensity of this rainfall in comparison with historical hydrological data, we employed geographical information systems (GIS). Then, we recruited a representative sample of the affected population and another population sample that lived at the time of this disaster in adjacent geographical areas that were not affected. Both groups were randomly selected in primary care practices, from December 1st 2012 to January 31st 2013. All participants, 70 from the affected areas and 91 from the non-affected, filled a sociodemographic questionnaire and the trauma questionnaire (TQ) to identify and rate PTSD symptoms. RESULTS: Our GIS analysis confirmed that the amount of precipitation in 2012 in the areas affected by the flood was exceptionally high compared with historical average rainfall data (461l per square metre vs 265). Individuals who resided in the affected areas at the time of the flood were at much higher risk of developing PTSD symptoms (OR: 8.18; 95% CI: 3.99-17.59) than those living in adjacent, non-affected localities. Among the sociodemographic variables included in this study, only material and financial losses were strongly associated with the onset of PTSD (P < 0.001). Physical risk during this life-threatening catastrophe also indicated a positive correlation with later development of PTSD symptoms; however, it did not reach statistical significance (P = 0.06). CONCLUSIONS: Populations affected by severe floods may suffer an increase of PTSD symptoms in the following months. This finding, along with the importance of material losses as a predictor for such disorder, may help develop effective plans to minimize the negative impact of these natural disasters on public health.

Effect of Diet and Exercise on the Peripheral Immune System in Young Balb/c Mice.

Although diet and exercise clearly have an influence on immune function, studies are scarce on the effect caused by exercise and the consumption of a carbohydrate-rich or fat-rich diet on the peripheral immune system. The aim of the present study was to evaluate the effect of exercise and the two aforementioned unbalanced diets on young Balb/c mice, especially in relation to BMI, the level of glucose, and the percentage of lymphocyte subpopulations in peripheral blood. The changes found were then related to the synthesis of leptin and adiponectin as well as the production of oxidative stress. The increase in BMI found with the carbohydrate-rich and fat-rich diets showed correlation with the levels of leptin and adiponectin. An increase in leptin and a decrease in adiponectin directly correlated with an increase in total lymphocytes and CD4+ cells and with a decrease in B cells. The increase in leptin also correlated with an increase in CD8+ cells. Glycemia and oxidative stress increased with the two unbalanced diets, negatively affecting the proliferation of total lymphocytes and the percentage of B cells, apparently by causing alterations in proteins through carbonylation. These alterations caused by an unbalanced diet were not modified by moderate exercise.

Comparación de datos anatomopatológicos entre biopsia de próstata y pieza de prostatectomía radical en pacientes con cáncer de bajo y muy bajo riesgo / Comparison of pathological data between prostate biopsy and radical prostatectomy specimen in patients with low to very low risk prostate cancer

Objetivo: Analizar la correlación entre los datos anatomopatológicos encontrados en prostatectomía radical y la biopsia previa realizada en pacientes con cáncer de próstata de bajo riesgo. Material y métodos: Se ha realizado un estudio descriptivo transversal para valorar las características de las prostatectomías radicales realizadas en nuestro centro desde enero de 2012 a noviembre de 2014. Los criterios de inclusión fueron pacientes con enfermedad de bajo riesgo (cT1c-T2a, PSA ≤ 10 ng/ml y Gleason ≤ 6). Fueron excluidos aquellos con menos de 8 cilindros en la biopsia, número de cilindros afectos no especificados, tacto rectal no recogido en historia clínica o biopsia realizada en otro centro. Resultados: De las 184 prostatectomías realizadas en este periodo, 87 pacientes cumplían con los criterios de inclusión y 26 de estos presentaban < 3 cilindros afectados y un PSAd ≤ 0,15 (muy bajo riesgo). Encontramos en la muestra total un porcentaje de infragradación (Gleason ≥ 7) del 18,4% (IC 95%: 10,3-27,6%) y de afectación extracapsular (pT3) del 10,35% (IC 95%: 4,6-17,2%). El porcentaje de márgenes positivos fue del 21,8% (IC 95%: 12,6-29,9%). En el grupo de muy bajo riesgo no encontramos ningún caso de afectación extracapsular y un solo caso de infragradación (Gleason 7 [3 + 4]) representando un 3,8% del total (IC 95%: 0-12,5%). Resultaron ser variables predictoras de no correlación (estadio ≥ pT3a o infragradación) el grupo de riesgo inicial, volumen, PSA densidad y cilindros afectados. Conclusiones: El volumen prostático, el valor del PSA densidad, el número de cilindros afectados y el grupo de riesgo inicial del paciente influyen en la aparición de datos de mal pronóstico anatomopatológico en la pieza de prostatectomía radical (afectación extracapsular y Gleason ≥ 7)

Objective: To analyze the correlation between pathological data found in radical prostatectomy and previously performed biopsy in patients at low risk prostate cancer. Material and methods: A descriptive, cross-sectional study was conducted to assess the characteristics of radical prostatectomies performed in our center from January 2012 to November 2014. The inclusion criteria were patients with low-risk disease (cT1c-T2a, PSA ≤ 10 ng/mL and Gleason score ≤ 6). We excluded patients who had fewer than 8 cores in the biopsy, an unspecified number of affected cores, rectal examinations not reported in the medical history or biopsies performed in another center. Results: Of the 184 patients who underwent prostatectomy during this period, 87 met the inclusion criteria, and 26 of these had < 3 affected cores and PSA density ≤ .15 (very low risk). In the entire sample, the percentage of undergrading (Gleason score ≥ 7) and extracapsular invasion (pT3) was 18.4% (95% CI 10.3 − 27.6) and 10.35% (95% CI 4.6 − 17.2), respectively. The percentage of positive margins was 21.8% (95% CI 12.6-29.9). In the very low-risk group, we found no cases of extracapsular invasion and only 1 case of undergrading (Gleason 7 [3 + 4]), representing 3.8% of the total (95% CI 0 - 12.5). Predictors of no correlation (stage ≥ pT3a or undergrading) were the initial risk group, volume, PSA density and affected cores. Conclusions: Prostate volume, PSA density, the number of affected cores and the patient's initial risk group influence the poor pathological prognosis in the radical prostatectomy specimen (extracapsular invasion and Gleason score ≥ 7)

CONCLUSIONS: Prostate volume, PSA density, the number of affected cores and the patient's initial risk group influence the poor pathological prognosis in the radical prostatectomy specimen (extracapsular invasion and Gleason score≥7).

Fontan procedure: imaging of normal post-surgical anatomy and the spectrum of cardiac and extracardiac complications.

Univentricular congenital heart diseases include a range of entities that result in a functionally single ventricular chamber. Although the only curative therapy is cardiac transplantation, there are several palliative surgical techniques that prevent ventricular volume overload, diverting part or all the systemic venous circulation into the pulmonary arteries. The modern Fontan procedure, which consists of anastomosing both the superior (SVC) and inferior vena cava (IVC) to the right pulmonary artery (RPA), is nowadays the last step before transplantation. The importance of imaging in these entities lies not only in the understanding of the new circuit established after surgical correction, but also in the early detection of the wide spectrum of cardiac and extracardiac complications that can occur due to the new physiological condition. Due to the increased survival of these patients, long-term complications are becoming more common. The main cardiac complications are atrial enlargement, ventricular dysfunction, and stenosis or thrombosis of the conduit. Pulmonary artery stenosis, pulmonary arteriovenous fistulae (PAVF), systemic-pulmonary veno venous shunts (VVS), hepatic congestion, cardiac cirrhosis, and protein-losing enteropathy are potential extracardiac complications.

Colonization levels of Streptococcus mutans between mother and infant: a postnatal prospective cohort study.

OBJECTIVE: To investigate the possible association between maternal S. mutans levels and those of the infant during the period between birth and 5 months and evaluate possible risk factors in the S mutans colonization. STUDY DESIGN: A prospective cohort study was carried out comprising 62 infants and their mothers, selected at the time of childbirth. For each infant, a sample swab was taken at 0, 15, 30, 90, and 150 days postpartum; on the same days, a sample was obtained from the mothers. TYCSB medium was employed for identifying the microorganism, which was later confirmed by Gram staining, the catalase activity test, and the API strep test. RESULTS: The final total sample consisted of 60 infants, from which S. mutans was detected in only 2 (3%) at the 150th day of oral sample collection. Of the sample of 60 mothers, 54 exhibited colonization levels. CONCLUSIONS: In the studied sample pairs up to 150 days, it was not possible to demonstrate the presence of a direct relationship between maternal S. mutans oral levels.

Intermittent fasting promotes bacterial clearance and intestinal IgA production in Salmonella typhimurium-infected mice.

The impact of intermittent fasting versus ad libitum feeding during Salmonella typhimurium infection was evaluated in terms of duodenum IgA levels, bacterial clearance and intestinal and extra-intestinal infection susceptibility. Mice that were intermittently fasted for 12 weeks or fed ad libitum were infected with S. typhimurium and assessed at 7 and 14 days post-infection. Next, we evaluated bacterial load in the faeces, Peyer's patches, spleen and liver by plate counting, as well as total and specific intestinal IgA and plasmatic corticosterone levels (by immunoenzymatic assay) and lamina propria IgA levels in plasma cells (by cytofluorometry). Polymeric immunoglobulin receptor, α- and J-chains, Pax-5 factor, pro-inflammatory cytokine (tumour necrosis factor-α and interferon-γ) and anti-inflammatory cytokine (transforming growth factor-ß) mRNA levels were assessed in mucosal and liver samples (by real-time PCR). Compared with the infected ad libitum mice, the intermittently fasted infected animals had (1) lower intestinal and systemic bacterial loads; (2) higher SIgA and IgA plasma cell levels; (3) higher mRNA expression of most intestinal parameters; and (4) increased or decreased corticosterone levels on day 7 and 14 post-infection, respectively. No contribution of liver IgA was observed at the intestinal level. Apparently, the changes following metabolic stress induced by intermittent fasting during food deprivation days increased the resistance to S. typhimurium infection by triggering intestinal IgA production and presumably, pathogen elimination by phagocytic inflammatory cells.

Effect of glycophosphopeptide on the lymphocytes and IgA of Olympic platform divers.

AIM: The aim of this paper was to evaluate the effect of a treatment with glycophosphopeptide on Olympic high platform divers during training and competition by measuring lymphocytes and cortisol in peripheral blood, and secretory immunoglobin A in saliva (sIgA). METHODS: Two groups of 8 divers were given a 14-day treatment of capsules (Gp or placebo) three times per day. Measurements of the peripheral blood lymphocytes (TCD3+, TCD4+ and T CD8+), plasma cortisol and IgA levels in saliva were made on day 0, 21 and 150. RESULTS: There was no significant difference found between the Gp- and placebo-treated groups regarding the increase in IgA between basal and first, or first and second measurements. The fact that there was a significant increase in S-IgA (9.89 ± 0.44 to 10.59±0.55, P=0.001) and B CD19+ (345.13±108.24 to 484.75±120.54, P=0.025) in the Gp- and not in the placebo-treated group between the basal and first measurement was due to the variation among the athletes of the latter group, and not the increase itself, indicating that Gp acted as an immunomodulator. It was apparently the exercise and not the Gp treatment that caused the increase in S-IgA and B CD19+ at the first and second measurements. CONCLUSION: The current study reports that with athletes who practiced moderately intense exercise, which stimulated the immune response, a Gp treatment of two weeks seems to have acted only as an immunomodulator that reduced the variation in the increased levels of IgA and B CD19+.

Germination, survival and growth of three vascular plants on biological soil crusts from a Mexican tropical desert.

Information about the effects of biological soil crusts (BSC) on germination, seedling survival and growth of vascular plants is controversial because they can have positive, neutral or negative effects. This controversy may be because most studies conducted until now have just analysed one or two recruitment stages independently. To understand the BSC effects on vascular plants, it is necessary to consider each stage of the recruitment process and synthesise all this information. The goal of this study was twofold. First, we analyse germination, seedling survival and growth of three vascular plants (Agave marmorata, Prosopis laevigata and Neobuxbaumia tetetzo) on BSC (cyanobacteria and mixed crust) from a tropical desert region of south-central México. Second, we synthesise the information to determine the total effect of BSC on plant species performance. We conducted experiments under controlled conditions to evaluate the proportion of germinated seeds, proportion of surviving seedlings and seedling dry weight in BSC and bare soil. Results showed that BSC have different effects on germination, seedling survival and growth of plant species. Plant species performance was qualitatively higher on BSC than bare soil. The highest performance of A. marmorata and P. laevigata was observed on cyanobacteria and mixed crusts, respectively. The highest performance of N. tetetzo was on both crust types.

Myeloperoxidase binds to and kills Entamoeba histolytica trophozoites.

During amebic invasion, neutrophils are a key component in either protecting against invading trophozoites or contributing to tissue damage. Upon degranulating or being lysed, neutrophils release toxic substances that can kill amebas as well as damage host tissue. In a previous study we identified a protein from nonspecifically stimulated peritoneal exudates of hamster that has peroxidase and marked amebicidal activity. In the current study we analyzed the in vitro amebicidal effect of purified hamster myeloperoxidase (MPO). The results demonstrate that MPO must bind directly to the surface of Entamoeba histolytica trophozoites in order to carry out amebicidal activity by using the H(2) O(2) produced by the amebas themselves. Myeloperoxidase-incubated amebas showed important morphological and ultrastructural alterations that increased with incubation time. Changes included an increase of vacuoles in the cytoplasm, a decrease of glycogen, alterations of nuclear morphology and disturbances in the plasma membrane culminating in complete ameba destruction.

Aggressive versus Low Dose Inhibition of the Renin-Angiotensin System for the Treatment of Microalbuminuria in Type 2 Diabetic Patients: A Pilot Study.

Objective. This study compares low dose versus aggressive inhibition of the renin angiotensin system (RAS) to treat microalbuminuria (MA). Methods. Patients with MA after a run-in period to control BP to <130/80 mm Hg with 10 mg benazepril plus other drugs and HbA1c levels to <8.0% were randomized to either continue 10 mg benazepril (N = 12) or to take maximal doses of benazepril plus losartan in monthly stepwise increases to achieve normoalbuminuria (N = 11). Because MA is associated with CVD and inflammation, carotid intima medial thickness (CIMT) and endothelial function by peripheral arterial tonometry (PAT) as surrogate indices of atherosclerosis and highly sensitive C-reactive protein (hs-CRP) to assess inflammation were measured every six months. Results. BP, HbA1c levels, albumin : creatinine ratios, CIMT, PAT, and hs-CRP did not differ over a mean of 12 months between the two groups. Conclusions. Aggressive inhibition of the RAS is unnecessary to treat MA.

[Early experience in laparoscopic radical prostatectomy using the laparoscopic device for umbilical access SILS Port]. / Experiencia inicial en prostatectomía radical laparoscópica con el dispositivo de acceso laparoscópico umbilical Single-Incision Laparoscopic Surgery Port.

Since 2007, various urological procedures have been performed with laparoendoscopic single-site surgery (LESS surgery), including nephrectomy, pyeloplasty, simple prostatectomy and, with the refinement of laparoscopic instrumentation, radical prostatectomy. This paper reports our initial experience in radical prostatectomy using the SILS Port from Covidiem and two lateral 5-mm trocars for triangulation. The SILS Port allows for accurate, simple insertion through a Hadson incision. The flexible port accommodates three 5-mm cannulas or two 5-mm cannulas and a 12-mm port for easier instrument exchange through a single incision. This approach decreases morbidity from bleeding, hernia and/or internal organ damage and improves cosmetic. One-port single-incision laparoscopy is part of the natural development of minimally invasive surgery. Future research is required to assess the intraoperative and postoperative benefits of LESS surgery as compared to standard laparoscopy.
