The treatment of the dentofacial abscess was always surgical because the evacuation of the purulent collection and removal of the cause are mandatory. Large abscesses, especially those that reach the submandibular space, require laboratory and imaging exams, but small abscesses restricted to the buccal space can be successfully treated by diluting the purulent collection with saline solution using needle and syringe.

Purpose: To analyze spread of odontogenic infections in the elderly, especially the prevalence and characteristic multidetectorcomputed tomography (MDCT) findings.Materials and methods: Ninety-seven patients with odontogenic infection who underwent 64-row MDCT were evaluated inthis study. The study patients comprised 31 elderly patients (60 years) and 66 adults (< 60 years). Age, gender, location ofcausal tooth, and spread of odontogenic infections with MDCT were analyzed.Results: The elderly patients (74.2%) had higher ratio with female compared to the adults (57.6%). The buccal space (93.5%)was the most common spread of odontogenic infections for the elderly patients, followed by the masticator space (54.8%) andsubmandibular space (45.2%), whereas the buccal space (97.0%) was the most common spread of odontogenic infections for theadults, followed by submandibular space (65.2%) and masticator space (51.5%). Logistic multivariate regression analysis forodontogenic infections in the elderly demonstrated that the gender (odds ratio = 3.462, P = .024) and submandibular space (oddsratio = 0.168, P = .013) were significant variable.Conclusions: The study showed the prevalence and characteristic MDCT findings of spread of odontogenic infections in theelderly.

The influence of small variations in the composition on the corrosion behavior of Co-Cr-Mo alloys has been studied using scanning electron microscopy (SEM), energy dispersive x-ray analysis (EDX), and electrochemical measurements. SEM and EDX data were correlated with data from in vitro corrosion measurements involving repassivation and also potentiostatic anodic polarization measurements. Specimens studied included the four alloys shown in Table 1. Corrosion tests were conducted in Hanks' physiological saline solution which has a pH of 7.4 and was held at a temperature of 37°C. Specimens were mechanically polished to a surface finish with 0.05 µm A1203, then exposed to the solution and anodically polarized at a rate of 0.006 v/min. All voltages were measured vs. the saturated calomel electrode (s.c.e.).. Specimens had breakdown potentials near 0.47V vs. s.c.e.

Although erythrophagocytosis by various species of Entamoeba is a well known phenomenon this has not yet been studied in detail at the ultrastructural level. The present work deals with the description of the incorporation process of erythrocytes by trophozoites of E. histolytica. For this study, trophozoites of E. histolytica, HK-9:NIH strain cultured in axenic conditions and washed human erythrocytes were placed on a hot plate at 37°C in physiological saline solution. After 5 minutes, 2.5% glutarldehyde was added and the samples were processed according to conventional techniques for electron microscopy.Based upon light microscopy studies on living trophozoites in contact with erythrocytes, it seems that erythrophagocytosis only takes place in one pole of the parasite.

Abstract This article summarizes the design and evaluation of a new augmentative and alternative communication (AAC) interface strategy for people with complex communication needs and severe physical limitations. This strategy combines typing, gesture recognition, and word prediction to input text into AAC software using touchscreen or head movement tracking access methods. Eight individuals with movement limitations due to spinal cord injury, amyotrophic lateral sclerosis, polio, and Guillain Barre syndrome participated in the evaluation of the prototype technology using a head-tracking device. Fourteen typical individuals participated in the evaluation of the prototype using a touchscreen.
