Maxillary sinusitis after augmentation of the maxillary sinus floor: a report of 2 cases.

Augmentation of the floor of the maxillary sinus with an autogenous bone graft is a generally accepted pre-implantology procedure to enable successful placement of endosseous implants in an optimal prosthetic position. As reported in the literature, complications of the sinus augmentation procedure predominantly consist of disturbed wound healing, hematoma, sequestration of bone, and transient maxillary sinusitis. 1,2 The last complication can occur as a result of contamination of the maxillary sinus with oral or nasal pathogen or because of a lack of asepsis during the surgical procedure. 3 Other causes are ostial obstruction due to postoperative swelling of the maxillary mucosa 4-6 and nonvital bony fragments freely floating in the maxillary sinus. 7 The incidence of maxillary sinusitis after augmentation of the sinus floor with iliac crest bone grafts ranges from 0% to 27%. 8-16 However, one has to consider that these data are derived from clinical studies in which the presence of maxillary sinusitis was not scored according to standard criteria in the field of otolaryngology for the diagnosis of sinusitis, 17-24 and specific preoperative evaluation of sinus drainage was not performed. Timmenga et al 25 reported that clearance of the maxillary sinus is rarely compromised after sinus floor augmentation, and that the development of a chronic maxillary sinusitis, with all its therapeutic consequences, still has to be considered as a rare condition. Between 1988 and 1998, 156 patients were treated in our clinic; 7 patients (4%) developed a transient (subacute) sinusitis, and 2 patients (2%) developed a chronic purulent maxillary sinusitis. In this report, these 2 complicated cases of chronic purulent maxillary sinusitis following augmentation of the maxillary sinus with autogenous bone grafts are discussed and guidelines for specific treatment of both transient and chronic maxillary sinusitis are given.
Integrating a usable security protocol for user authentication into the requirements and design process

L'utilisabilite et la securite sont des elements cruciaux dans le processus d'authentification des utilisateurs. L'un des defis majeurs auquel font face les organisations aujourd'hui est d'offrir des systemes d'acces aux ressources logiques (par exemple, une application informatique) et physiques (par exemple, un bâtiment) qui soient a la fois securisees et utilisables. Afin d'atteindre ces objectifs, il faut d'abord mettre en œuvre les trois composantes indispensables que sont l'identification (c.-a-d., definir l'identite d'un utilisateur), l'authentification (c.-a-d., verifier l'identite d'un utilisateur) et l'autorisation (c.-a-d., accorder des droits d'acces a un utilisateur). Plus particulierement, la recherche en authentification de l'utilisateur est essentielle. Sans authentification, par exemple, des systemes informatiques ne sont pas capables de verifier si un utilisateur demandant l'acces a une ressource possede les droits de le faire. Bien que plusieurs travaux de recherche aient porte sur divers mecanismes de securite, tres peu de recherches jusqu'a present ont porte sur l'utilisabilite et la securite des methodes d'authentification des utilisateurs. Pour cette raison, il nous parait necessaire de developper un protocole d'utilisabilite et de securite pour concevoir les methodes d'authentification des utilisateurs. La these centrale de ce travail de recherche soutient qu'il y a un conflit intrinseque entre la creation de systemes qui soient securises et celle de systemes qui soient facile d'utilisation. Cependant, l'utilisabilite et la securite peuvent etre construites de maniere synergique en utilisant des outils d'analyse et de conception qui incluent des principes d'utilisabilite et de securite des l'etape d'Analyse et de Conception de la methode d'authentification. Dans certaines situations il est possible d'ameliorer simultanement l'utilisabilite et la securite en revisitant les decisions de conception prises dans le passe. Dans d'autres cas, il est plus avantageux d'aligner l'utilisabilite et la securite en changeant l'environnement regulateur dans lequel les ordinateurs operent. Pour cette raison, cette these a comme objectif principal non pas d'adresser l'utilisabilite et la securite posterieurement a la fabrication du produit final, mais de faire de la securite un resultat naturel de l'etape d'Analyse et de Conception du cycle de vie de la methode d'authentification. ______________________________________________________________________________ MOTS-CLES DE L’AUTEUR : authentification de l'utilisateur, utilisabilite, securite informatique, controle d'acces.
Multiobjective Metaheuristics for Traffic Grooming in Optical Networks

Currently, wavelength division multiplexing technology is widely used for exploiting the huge bandwidth of optical networks. It allows simultaneous transmission of traffic on many nonoverlapping channels (wavelengths). These channels support traffic demands in the gigabits per second (Gb/s) range; however, since the majority of devices or applications only require a bandwidth of megabits per second (Mb/s), this is a waste of bandwidth. This problem is efficiently solved by multiplexing a number of low-speed traffic demands (Mb/s) onto a high-speed wavelength channel (Gb/s). This is known as the traffic grooming problem. Since traffic grooming is an NP-hard problem, in this paper, we propose two novel multiobjective evolutionary algorithms for solving it. The selected algorithms are multiobjective variants of the standard differential evolution (DEPT) and variable neighborhood search. With the aim of ensuring the performance of our proposals, we have made comparisons with the well-known fast Nondominated Sort Genetic Algorithm (NSGA-II), Strength Pareto Evolutionary Algorithm 2, and other approaches published in the literature. After performing diverse comparisons, we can conclude that our novel approaches obtain promising results, highlighting in particular the performance of the DEPT algorithm.
Behind the mask. Journey through an epidemic: some observations of contrasting public health responses to SARS

SARS has been called the first global epidemic of the 21st century and has been the cause of a massive and varied public health response in many countries of the world. This report describes observations made by two authors on a journey from Manchester in the United Kingdom to Chiang Mai in Thailand during the peak of global transmission. The public response to SARS, particularly characterised by the wearing of face masks, seemed to outstrip official guidance. Though of uncertain protective benefit, the wearing of masks may have contributed to the awareness of the collective and personal responsibility in combating infectious disease. Active and empowered involvement of the general public in implementing and cooperating with public health control measures supported by national and international authorities has clearly helped to bring SARS under control. The public health significance of such potent symbols as the face mask may be considered in strategies to tackle other emerging infections.

Acute Pancreatitis in Patients 70 Years of Age or Older

Objective: To explore the incidence and severity of pancreatitis and to assess the outcome of all measures taken to treat gallstones in following recovery from pancreatitis in patients 70 years of age or older in a community-based setting. Methods: All patients with pancreatitis as diagnosis in Uppsala, Sweden, 2003–2005, were identifi ed retrospectively. Data relevant for assessing etiology and follow-up treatment were extracted from the patients’ histories. The electronic patient administrative system was crosschecked to determine mortality within 30 days after admission. Result: Altogether 148 admissions for 119 patients, including 48 men, were registered. On 29 occasions, admission was for relapse after a previous episode. Mortality within 30 days was 4/148 (2.7%). Twenty-two patients with gallstone induced acute pancreatitis underwent cholecystectomy and 27 patients underwent ERC with endoscopic sphincterotomy during follow-up. In a life table analysis, the probability of remaining relapse-free in the absence of cholecystectomy or endoscopic sphincterotomy was estimated to 95% (95% confi dence interval [CI] 91%–98%) two weeks after discharge and 92% (CI 88%–97%) eight weeks after discharge. Conclusion: Although pancreatitis in most cases is not a serious condition, it may become life threatening for elderly people. In patients with gallstone induced pancreatitis, accurate timing of cholecystectomy or endoscopic sphincterotomy in the follow-up period is crucial in order to preclude re-admissions for relapses.
Behaviour and personality of pet rabbits and their interactions with their owners

The behaviour and personality of 102 pet rabbits and their interactions with their owners were assessed in their home environment. Information was obtained by interviews with the owner and by direct observation, and the owners were asked to describe the personality of their rabbit. A 10-minute assessment of the rabbit's behaviour in its normal environment was then carried out. Owners who were confident in handling their rabbit handled them more frequently and rabbits that were handled more frequently struggled less when they were being handled. Rabbits observed with a companion spent the largest proportion of their time engaged in social behaviour, and rabbits observed out of a hutch spent significantly more time grazing, hopping and playing. Owners used a wide range of adjectives to describe their rabbits' personalities with the most common term being ‘friendly’.
Polymorphism of beta-adrenergic receptors and susceptibility to open-angle glaucoma.

PURPOSE The human trabecular meshwork and ciliary body, which express beta-adrenergic receptors (ADRB1 and ADRB2), control aqueous humor dynamics. We investigated associations of ADRB polymorphisms with open-angle glaucoma (OAG), because ADRB gene polymorphisms alter receptor function. METHODS We studied 240 Japanese controls and 505 Japanese OAG patients including 211 with primary open-angle glaucoma (POAG), and 294 with normal-tension glaucoma (NTG). Associations of four polymorphisms (Ser49Gly and Arg389Gly in the ADRB1 gene; Arg16Gly and Gln27Glu in the ADRB2 gene) were compared between patients and controls. Age, intraocular pressure (IOP), and visual field defects at diagnosis were examined for associations with polymorphisms. RESULTS The Arg389Gly polymorphism in the ADRB1 gene showed significantly different allele and genotype frequencies in patients with NTG than in controls (p = 0.004 and 0.006, respectively). Other polymorphisms did not show a significant frequency difference. In POAG patients, carriers of Gly16 in the ADRB2 gene were significantly younger at diagnosis than noncarriers (p<0.001). The IOP at diagnosis was significantly higher in OAG patients carrying 27Glu in the ADRB2 gene than in patients without this allele (p<0.001). Clinical characteristics of OAG patients did not differ significantly in relation to other polymorphisms. CONCLUSIONS Certain polymorphisms of the ADRB1 and ADRB2 genes influence the pathophysiology of OAG in Japanese patients.
Trophodynamic control by clupeid predators on recruitment success in Baltic cod

Throughout the 1980s, reproductive success of the top-predator cod declined and stock sizes of the main prey species herring and especially sprat, important planktivorous predators in the system, increased substantially. Although the hydrographic conditions conducive for survival of early life stages improved during the 1990s, recruitment success of cod remained far below average. As clupeids have been identified as major predators on cod eggs and larvae in the Baltic, increased predation may be an important factor hampering stock recovery. Results from stomach content analysis of herring and sprat during the spawning season of 1988–1995 and ichthyoplankton surveys in the Bornholm Basin (the only important spawning area of cod in the Central Baltic in this period) allow a comparison of estimated consumption rates by the predator populations with standing stocks and production rates of cod eggs and larvae. Despite uncertainties in the estimation procedure, the findings confirm substantial predation on cod eggs by both clupeid species. Especially at the beginning of the cod-spawning season, characterized by low zooplankton availability, sprat consumed a considerable proportion of the eggs produced. In 1993, the relative importance of zooplankton as prey increased, while fish eggs were encountered more rarely. In contrast, predation by herring remained on the same level or even increased, especially late in the spawning season. The larval stage of cod is not substantially affected by predation owing to limited spatial overlap between prey and predator.
Narrative, Rhetoric, and the Origins of Logic

In Vom Mythos zum Logos (1940), a book that became emblematic of a now rather passe, idealized view of ancient Greek culture, Wilhelm Nestle proposed that the greatest achievement of the Greeks was the abandonment of the mythological interpretation of the world in favor of a rationalist model, developed with the tools of analytic thinking. Nestle’s account has since been supplanted by newer approaches, which found a lot more than myth in mythos and a lot less than pure reason in logos. However, if we restrict the meaning of his two terms and read mythos simply as “story” and logos as “logic,” Nestle’s catchphrase takes us back to a seminal event in cultural history, an event that has not been examined with the attention it deserves. More specifi cally, this essay argues that what we call, for short, “the birth of logic” can best be understood not as the abandonment of the narrative mode
Differential Protein Expression in Small Intestinal Neuroendocrine Tumors and Liver Metastases

Objective Small intestinal neuroendocrine tumors (SI-NETs) are often detected after they have become metastatic. Using a novel protein array, we identified pathways important in SI-NET metastasis development in surgically resected patients. Methods Paired primary tumors and liver metastases from 25 patients undergoing surgical resection for metastatic SI-NETs were harvested. Extracted proteins were separated by sodium dodecyl sulfate gel and multiplex immunoblots were performed with 136 antibodies. Significant Analysis of Microarray was used to select for differentially expressed proteins. A tissue microarray was constructed from 27 archived specimens and stained by immunohistochemistry. Results Comparing primary SI-NETs with matched normal small-bowel mucosa, 9 proteins were upregulated and cyclin E was downregulated. The SI-NET liver metastases demonstrated upregulation of P-ERK and p27 but downregulation of CDK2 and CDC25B. When comparing primary SI-NET with their paired liver metastases, cyclin E demonstrated a significant upregulation in the liver metastasis. Tissue microarray demonstrated higher p38 expression and lower Cdc 25b expression in SI-NETs versus liver metastases and confirmed higher expression of p27 in liver metastases versus normal liver. Conclusions Few studies have compared protein expression in paired primary and metastatic SI-NETs. Our findings reveal changes in a limited number of proteins, suggesting that these may be targets for therapy.
Germline transformation of the malaria vector, Anopheles gambiae, with the piggyBac transposable element

Germline transformation of the major African malaria vector, Anopheles gambiae, was achieved using the piggyBac transposable element marked with the enhanced green fluorescent protein (EGFP) injected into mosquito embryos. Two G1 generation male mosquitoes expressing EGFP were identified among 34 143 larvae screened. Genomic Southern data and sequencing of the piggyBac insertion boundaries showed that these two males arose from one piggyBac insertion event in the injected G0 embryos. Genetic cross data suggest that the insertion site of the element either resulted in, or is tightly linked to, a recessive lethal. This was demonstrated by a deficiency in the number of EGFP‐expressing offspring from inbred crosses but expected ratios in outcrosses to non‐transformed individuals and failure to establish a pure‐breeding line. The insertion was weakly linked to the collarless locus on chromosome 2 and was shown by in situ hybridization to be located in division 28D of that chromosome. Particularly high levels of expression were observed uniformly in salivary glands and, in most individuals, in the anterior stomach. An improvement in the injection technique at the end of the studies resulted in increased G0 hatching, transient expression and EGFP‐expression rates among G1 progeny.

Linear Time Varying Systems Stability: A Bond Graph Approach

A bond graph model of a Linear Time-Varying (LTV) system is presented. This bond graph can have LTV constitutive relations of the elds, and transformer and gyrator LTV modules. Hence, a junction structure and the state variables equation of the bond graph can be obtained. Also, a Lemma to determine the stability conditions of a LTV system based on the corresponding bond graph model is proposed. In order to show the e¤ectiveness of the proposed methodology, two examples are solved.
LDM and TDM performance evaluation for next generation broadcasting system use cases

LDM is a new multiplexing technique, which grew out the Cloud-Txn concept for offering simultaneously stationary and mobile services. The main objective of this paper is to extend the comparison of LDM and TDM, testing their performance for different use cases, which are targeted as top-priority for the next generation broadcasting systems. The paper will also explore the limits of injection levels, modulation, coding relations and spectrum flexibility of LDM.
A Formal Framework for Mobile Ad hoc Networks in Real-Time Maude

Mobile ad hoc networks (MANETs) are increasingly popular and deployed in a wide range of environments. However, it is challenging to formally analyze a MANET, both because there are few reasonably accurate formal models of mobility, and because the large state space caused by the movements of the nodes renders straight-forward model checking hard. In particular, the combination of wireless communication and node movement is subtle and does not seem to have been adequately addressed in previous formal methods work. This paper presents a formal executable and parameterized modeling framework for MANETs in Real-Time Maude that integrates several mobility models and wireless communication. We illustrate the use of our modeling framework with the Ad hoc On-Demand Distance Vector (AODV) routing protocol, which allows us to analyze this protocol under different mobility models.
Catecholamine Dysfunction in Attention-Deficit/Hyperactivity Disorder: An Update

Attention-deficit/hyperactivity disorder (ADHD) is a heterogeneous disease that affects children, adolescents, and adults. Genetic research has confirmed that there is a large hereditary component to this condition and has helped identify some of the genes associated with it. Among these are several genes associated with the catecholaminergic system including the dopamine receptor genes (DRD4 and DRD5), the dopamine transporter gene, and the gene for dopamine &bgr;-hydroxylase, which catalyzes conversion of dopamine to norepinephrine. Attention-deficit/hyperactivity disorder is believed to be a result of abnormalities in the frontal regions of the brain, particularly the prefrontal cortex and associated subcortical structures and circuits. Underpinning these abnormalities are disturbances of catecholamine neurotransmission. Studies have demonstrated that patients with ADHD have depleted levels of dopamine and norepinephrine thought to be largely the result of dysfunction of their respective transporter systems. The efficacy of stimulant agents confirms that the neurotransmitter abnormalities seen in ADHD are primarily catecholaminergic in origin. This article focuses on the catecholaminergic networks of higher cognitive functions such as attention and focus and of motor functions that may be associated with such networks, reviewing both the physiology of such functions and the pathophysiology of ADHD. Researchers are currently investigating whether other neurotransmitter systems may be partially involved and are investigating whether agents that affect these other systems will prove complementary to currently used treatments.
