Introduction: The Haller Cells are described as aerated ethmoidal cells, located in the inferior margin of the orbit, near the ostia of the maxillary sinuses. The Cone Beam Computed Tomography (CBCT) is widely used in dentistry, allowing acquisition of images of the craniofacial region. Objective: to identify in CBCT exams the Haller´s cell relationship with the following conditions: sinus disease, bony nasal septum deviation, endodontic treatment and periapical lesions. Materials and methods: 99 CBCT exams were used, from which 51 were included in the research criteria. The images were analyzed in the Xelis Dental® software to identify the presence or absence of the Haller Cell, as well as the relationship with the mentioned conditions. Results: Among the 51 CFCT exams evaluated, 35.3% presented Haller´s Cell on the right side and 23.5% on the left side. Whereas the relationship of the Haller Cells with one or more alterations mentioned here, on the right side we had it in 72% of the cases, while on the left side such relationship was present in 75% of the cases. Conclusion: CBCT exams that present the infraorbital margin allow to verify the presence or absence of the Haller Cell. In this sample, we verified a greater presence of endodontic cases, bony nasal septum deviation and sinus disease cases in individuals who presented Haller Cells.

AbstractWe describe a patient with oral-facial-digital syndrome (OFDS) with the following anomalies: cleft lip, cleft palate, micrognathia, hypertelorism, nasal septum deviation, thumb polydactyly in the right hand, and partial agenesis of the corpus callosum. In addition, the patient had optic disc coloboma in the left eye and subfoveal drusenoid deposit in the right eye, features of OFDS type IX. Subfoveal drusenoid deposit has not been previously reported in OFDS type IX. Evaluation of the fundus is necessary for diagnosis of OFDS.

Abstract Purpose: The aim of this study is to evaluate the effects of nasal septum deviation on the pharyngeal airway and cervico-craniofacial measurements on cephalometrics. Methods: The present study examines the skeletal and functional relationship of airway and septum deviation on the panoramic and cephalometric images of 50 patients with indication of orthodontic treatment, who were refeered to XXXXX University Faculty of Dentistry Departments of Pedodontics and Orthodontic for various reasons. Material of the study consists of 50 patients, including 25 patients (11 females and 9 males) with nasal septum deviation and 25 (12 females and 8 males) control group individuals without nasal septum deviation (23 females and 17 males; mean age: 10.1 ± 0.7 years). Results: The obtained data were evaluated using SPSS (21.0) package program. Regarding the data analysis, Mann-Whitney U Test Statistics was used for the analysis of two-variable data. (P>0.05). The difference between the groups was statistically significant (p<0.05) in the group with nasal septum deviation with regard to nasopharynx (af-pf1), vertical airway length (Eb-pm), and cervical colon curvature (OPT/CVT). Conclusion: Orthodontic patients detected with a nasal septum deviation of 4 mm and more on their panoramic radiographs are susceptible of various pharyngeal airway and cranio-cervical postural changes.

AbstractHans Kelsen is known both as a legal theorist and as an international lawyer. This article shows that his theory of international law is an integral part of the Kelsenian Pure Theory of Law. Two areas of international law are analysed: first, Kelsen's coercive order paradigm and its relationship to the bellum iustum doctrine; second, the Kelsenian notion of the unity of all law vis-à-vis theories of the relationship of international and municipal law. In a second step, the results of Kelsenian general legal theory of the late period – as interpreted and developed by the present author – are reapplied to selected doctrines of international law. Thus is the coercive order paradigm resolved, the unity of law dissolved, and the UN Charter reinterpreted to show that the concretization of norms as positive international law cannot be unmade by a scholarship usurping the right to make law.

Patient as service users have right and obligations to be hospitalized and patients also have the right to medical information in receiving medical practice services. This study aims to determine the relationship between patient attitudes towards the rights and obligations of being hospitalized in the hospital Pekanbaru Medical Center (PMC). This research method using observational analytic method with cross sectional design. The total sample used in this study 107 sample were taken as simpel random sampling. Chi square test is used to determine the relationship between variables. The data were processed using SPSS statistical software and analyzed using univariate and bivariate analyzes. Of the result obtained of the study namely the relationship between patient attitude to the rights and obligations of patient with chi-suare obtained pvalue 0.016 (<0,05), the relationship of attitude patients to the rights and obligations of choosing a doctor and class of patient care with chi-square obtained pvalue 0,070 (<0,05), the relationship of patient attitudes to the right and obligations of confidentiality of disease by inpatient medical staff with chi-square obtained pvalue 0,000 (<0,05), the relationship of patient attitudes to the rights and obligations of consent to the patient treatment with chi-square obtained pvalue 0,000 (<0,05), the relationship of patient attitudes to the right and obligation of patient safety with chi-square obtained pvalue 0,000 (<0,05), the relationship between patient attitudes towards the right and obligations of patient safety with chi-square obtained pvalue 0,000 (<0,05). Suggestions in order to protect what has been achieved in this case is his ability as effort of service is getting better in the future Keyword : Attitudes of patient, Rights and Obligations inpatient, Hospital

The speed-torque relationship of the right knee extensor muscle group was investigated in eight untrained subjects (28 +/- 2 yr old). Torque was measured at a specific knee angle during isokinetic concentric or eccentric actions at nine angular velocities (0.17-3.66 rad/s) and during isometric actions. Activation was by "maximal" voluntary effort or by transcutaneous tetanic electrical stimulation that induced an isometric torque equal to 60% (STIM 1) or 45% (STIM 2) of the voluntary isometric value. Torque increased (P less than 0.05) to 1.4 times isometric as the speed of eccentric actions increased to 1.57 rad/s for STIM 1 and STIM 2. Thereafter, increases in eccentric speed did not further increase torque. Torque did not increase (P greater than 0.05) above isometric for voluntary eccentric actions. As the speed of concentric actions increased from 0.00 to 3.66 rad/s, torque decreased (P less than 0.05) more (P less than 0.05) for both STIM 1 and STIM 2 (two-thirds) than for voluntary activation (one-half). As a result of these responses, torque changed three times as much (P less than 0.05) across speeds of concentric and eccentric actions with artificial (3.4-fold) than voluntary (1.1-fold) activation. The results indicate that with artificial activation the normalized speed-torque relationship of the knee extensors in situ is remarkably similar to that of isolated muscle. The relationship for voluntary activation, in contrast, suggests that the ability of the central nervous system to activate the knee extensors during maximal efforts depends on the speed and type of muscle action performed.
