Réflexions sur le régime des peuples dans la Grèce classique (Hérodote I, 133 ; Hippocrate, Ancienne médecine, C. 5 ; Thucydide I, 6) et sur le sens des mots de la famille de Diaita
Authors: Jouanna Jacques
Published: June 2014

L'objet de cette communication est d'abord de comparer pour la première fois trois textes relatifs au régime des peuples : Hérodote I 133 (avec une réinterprétation du sens) ; Hippocrate, Ancienne Médecine, c. 5 et Thucydide I, 6. Puis de la comparaison entre le texte d'Hippocrate et celui de Thucydide, où apparaissent des mots de la famille de diaita, naît un premier problème, celui de savoir quelles sont les relations entre le sens médical de « régime » et le sens plus général de « genre de vie ». Un réexamen des attestations les plus anciennes du substantif diaita chez les poètes (Alcée, Pindare, Eschyle) montre qu'à époque ancienne, le sens est général : le mot désigne la conduite ou le mode de vie d'un individu, de l'humanité ou d'un peuple. Il en résulte que le sens médical de « régime » en est une spécialisation parmi d'autres. Mais le sens de ce terme spécialisé en médecine varie suivant les auteurs médicaux ou les contextes. Le second grand problème abordé est celui d'un autre sens technique important, c'est-à-dire le sens juridique d'« arbitrage ». Un réexamen des emplois les plus anciens du verbe diaitan (chez Pindare) montre que le verbe a le sens de « régir, gouverner, administrer, régler ». C'est à partir de ce sens premier du verbe à l'actif que dérive le sens spécialisé d'« arbitrer ». D'un autre côté, c'est à partir du sens médio-passif « se régir, se conduire » que se développe le sens de « conduite, genre de vie » avec la spécialisation de l'emploi médical « régime ». L'étape première, si l'on veut remonter au-delà des textes, celle de l'étymologie, est plus hypothétique. Il n'est pas prudent de vouloir déduire d'un sens primitif hypothétique les sens qui sont avérés dans les témoignages les plus anciens.
Les Erotica pathémata de Parthénios de Nicée : des esquisses de poétique accentuelle signées d'acrostiches numériques
Authors: Biraud Michèle
Published: June 2014

The Erotica pathemata are not only an erudite compilation in prose, they are a poetic collection. Parthenius makes use of new rhythmic features of the language of his epoch : the evolution of the Greek language has replaced a quantitative rhythm, based on the length of syllables, by an accentual rhythm, based on the repetition of an accent of stressed words. With various ways, Parthenius tests the association of the following poetic devices : equality of number of accentuated syllables between cola or stanzas, repetition of the same accentuated clausula (with a ring-composition or in alternation), equal number of syllables in the corresponding stanzas or cola, assonances at the end of cola. Numerical acrostichs at the beginning or at the end of several texts guarantee the actuality of the segmentation in cola and the pertinence of the rhythmic features that have been discovered.
Faust, le Faustbuch et le Faustus Pseudo-Clémentin, ou la genèse d'un mythe
Authors: Pouderon Bernard
Published: June 2014

La confrontation de la plus ancienne version connue de la légende de Faust, celle du Faustbuch (1587), avec différents épisodes de la légende de Simon le Magicien montre que le rédacteur du Faustbuch connaissait la tradition simonienne, et qu'il en a usé pour composer la figure littéraire du docteur Faust. Mais d'où tenait-il ses informations ? De la tradition hérésiologique (Justin, Irénée), ou des Homélies clémentines, le tout premier roman chrétien (fin IIe - début IVe siècle) ? Il n'est pas impossible que l'anonyme ait déjà eu connaissance du contenu des Homélies, non encore publiées, soit par l'un de ses manuscrits, soit par l'édition de leur Epitomè. Mais le plus étrange est qu'il n'est pas impossible non plus que le Faust historique se soit appuyé sur des éléments de la légende de Simon (personnage d'Hélène, actes de magie) pour bâtir son propre personnage...
Molecular identification of the ompL1 gene within Leptospira interrogans standard serovars
Authors: Dezhbord Mehrangiz , Esmaelizad Majid , Khaki Pejvak , Fotohi Fariba , Zarehparvar Moghaddam Athena
Published: June 2014

Introduction: Leptospirosis, caused by infection with pathogenic Leptospira species, is one of the most prevalent zoonotic diseases in the world. Current leptospiral vaccines are mainly multivalent dead whole-cell mixtures made of several local dominant serovars. Therefore, design and construction of an efficient recombinant vaccine for leptospirosis control is very important. OmpL1 is an immunogenic porin protein that could be of special significance in vaccination and serodiagnosis for leptospirosis. Methodology: Three strains belonging to pathogenic L. interrogans were analyzed. The specific primers for proliferation of the ompL1 gene were designed. The amplified gene was cloned. In order to investigate the ompL1 nucleotide sequence and homological analysis of this gene, ompL1 genes cloned from standard vaccinal Leptospira serovars prevalent in Iran were sequenced and cloned. Results: PCR amplification of the ompL1 gene using the designed primers resulted in a 963 bp ompL1 gene product. The PCR based on the ompL1 gene detected all pathogenic reference serovars of Leptospira spp. tested. Based on alignment and phylogenetic analysis, although the ompL1 nucleotide sequence was slightly different within three vaccinal serovars (100%-85% identity), amino acid alignment of the OmpL1 proteins revealed that there would be inconsiderable difference among them. Conclusion: The ompL1 gene of the three isolates was well conserved, differing only by a total of 6 bp and the proteins by 2 amino acids. The cloned gene could be further used for expression and recombinant OmpL1 as an efficient and conserved antigen, and may be a useful vaccine candidate against leptospirosis in our region.

Authors: Ben Fguira Ines , Fourati Zaineb , Kamoun Fakher , Tounsi Slim , Jaoua Samir
Published: June 2014

Introduction: Conjugation is an excellent natural mode of DNA transfer in vivo between bacteria, particularly when these conjugative elements carry technological traits such as bacteriocin encoding genes. In the present work, the bacteriocinogenic plasmid pIBF4 from Bacillus thuringiensis responsible of Bacthuricin F4 synthesis was isolated and characterized. Methodology: To isolate pIBF4, the total plasmid DNA from a non-bacteriocin transposant carrying the mini-Tn10 spectinomycin selective marker was extracted and used to transform Escherichia coli strain Top10. PIBF4 was extracted from the obtained transformant and then subjected to restriction enzyme analysis. Plasmid curing experiments were conducted to test the stability of pIBF4 at a stringent temperature of 42°C. Conjugative behavior of pIBF4 was assessed by mating experiments using the non-bacteriocin transposant mutant as a donor strain and several Bacillus thuringiensis strains as recipients. Results: The pIBF4 plasmid was isolated and had a molecular weight of 19.1 kb. Ninety-five percent of cells retained the pIBF4 plasmid after 200 generations, demonstrating its high stability. PIBF4 was successfully transferred to Bacillus thuringiensis HD1CryB strain with a transfer frequency of 1x10-8 transconjugants per donor cell. The study of the recipient host range revealed that pIBF4 is specifically transferable to Bacillus thuringiensis strains with variable transfer frequencies depending on the recipient host strain. Conclusion: Our results show that pIBF4 is a 19.1 kb highly stable plasmid transferable by conjugation to Bacillus thuringiensis strains with deferent transfer frequencies.

Published: June 2014

Introduction: Knowledge of the etiology and antimicrobial susceptibility patterns of uropathogens is important for determining the best treatment option. This study aimed to determine the distribution and antibiotic susceptibility patterns of bacterial strains isolated from adult male outpatients. Methodology: Between November 2012 and April 2013, 3,105 community urine samples were analyzed from adult male patients who attended the Laboratorio Hidalgo, Buenos Aires, Argentina. Antimicrobial susceptibility testing was performed by the Kirby-Bauer disc diffusion method. Isolates resistant to third generation cephalosporin were tested for extended-spectrum beta-lactamase (ESBL) production using the double-disk synergy test. Results: Of the 3,105 urine samples analyzed, 791 (25.5%) had significant bacteriuria. The frequency of positive urine cultures increased significantly with patient age. Escherichia coli was isolated most frequently (47.3%), followed by Enterococcus faecalis (13.6%), and Klebsiella pneumoniae (11.9%). Gram-negative organisms represented 78.8% of urinary pathogens. The highest activities against Gram-negative bacteria were found with imipenem (99.0%), amikacin (98.1%), ertapenem (94.2%), fosfomycin (90.7%), and piperacillin-tazobactam (90.1%). The frequencies of ESBLs among E. coli, K. pneumoniae, and P. mirabilis were 15.2 %, 22.3%, and 8%, respectively. Fosfomycin, piperacillin-tazobactam, and nitrofurantoin were most effective against Gram-positive organisms. Conclusions: Fosfomycin may be an excellent option for cystitis treatment in patients without risk factors, whereas piperacillin-tazobactam is preferred for the treatment of parenchymatous UTIs, complicated UTIs, and UTIs associated with risk factors. To ensure the optimal selection of antibiotics, physicians should have access to up-to-date information about the local prevalence of antimicrobial resistance.

Published: June 2014

Introduction: Dengue is endemic and affects people in all Indonesian provinces. Increasing dengue cases have been observed every year in Sukabumi in West Java province. Despite the endemicity, limited data is available on the genetic of dengue viruses (DENV) circulating in the country. To understand the dynamics of dengue disease, we performed molecular and serological surveillance of dengue in Sukabumi. Methodology: A total of 113 patients were recruited for this study. Serological data were obtained using anti-dengue IgM and IgG tests plus dengue NS1 antigen detection. Dengue detection and serotyping were performed using real-time RT-PCR. Viruses were isolated and the envelope genes were sequenced. Phylogenetic and evolutionary analyses were performed to determine the genotype of the viruses and their evolutionary rates. Results: Real-time RT-PCR detected DENV in 25 (22%) of 113 samples. Serotyping revealed the predominance of DENV-2 (16 isolates, 64%), followed by DENV-1 (5 isolates, 20%), and DENV-4 (4 isolates, 16%). No DENV-3 was detected in the samples. Co-circulation of genotype I and IV of DENV-1 was observed. The DENV-2 isolates all belonged to the Cosmopolitan genotype, while DENV-4 isolates were grouped into genotype II. Overall, their evolutionary rates were similar to DENV from other countries. Conclusions: We revealed the distribution of DENV serotypes and genotypes in Sukabumi. Compared to data obtained from other cities in Indonesia, we observed the differing predominance of DENV serotypes but similar genotype distribution, where the infecting viruses were closely related with Indonesian endemic viruses isolated previously.

Global impacts of aflatoxin in maize: trade and human health
Authors: Wu F.
Published: June 2014

Maize is one of the most important agricultural commodities worldwide in terms of amounts produced, consumed, and traded. Hence, naturally occurring aflatoxin contamination in maize has important ramifications for both global trade and health. Aflatoxin is produced by certain species of the genusAspergillus in a variety of food crops, including maize, peanuts, and tree nuts. Over 100 nations have aflatoxin regulations, which are intended to protect human and animal health, but also incur economic losses to nations that attempt to export maize and other aflatoxin-contaminated commodities. These economic effects must be balanced against the health protection afforded by the regulations. It is important to acknowledge that, even in nations that have aflatoxin regulations, many individuals consume maize that has undergone no regulatory inspection, especially in nations where subsistence farming is widespread. Hence, aflatoxin contamination, exposure, and lack of regulation can also contribute to adverse effects on trade and health worldwide. This review, part of a special issue on aflatoxin in maize, describes economic and health effects of aflatoxin in maize on a global level. It ends with a story of an intervention that reduced maize consumption in one population in China, which is likely the main determinant of the reduction in liver cancer mortality in that population over the last 30 years, from reduced aflatoxin exposure.
El papel del locus de control del jefe entre el guanxi percibido y la conducta de liderazgo en los negocios familiares
Authors: Wu Tung-Ju , Tsai Hsien-Tang , Yeh Shang-Pao
Published: June 2014

La histórica y especial red de relaciones de la sociedad china se basa en lazos de sangre o en conexiones familiares emocionales de las que los negocios familiares son la mejor representación. Junto con la especialización de las estructuras corporativas, la cuestión clave de esta investigación será el poder y el liderazgo de los jefes sobre los subordinados, poniendo el énfasis en la personalidad del jefe. En el modelo de investigación –administración de un cuestionario a 147 negocios familiares de Taiwán, de los que 332 fueron válidos- combinamos el “guanxi” de las sociedades chinas, el poder, las tácticas para tener influencia y el locus de control. Mediante análisis jerárquicos de regresión los resultados muestran la estrecha relación que se da entre el poder de los jefes, el “guanxi” percibido y la conducta de liderazgo, en la que el locusde control de los jefes desempeña un papel destacado. Por eso se recomienda que la designación de jefes en esas empresas sea más cuidadosa. Además de la comunicación con los subordinados, debe prestarse atención a la adecuación entre personalidad y la competencia para mantener una eficiencia laboral y unas relaciones entre jefes y subordinados favorables.

Abstract – Nowadays the world economy suffers a global innovation gap, which reveals itself in essential disproportions in innovative development of particular countries. The deep inequality is also observed in the sphere of innovations between various geographical regions. Unfortunately, Russia does not belong to the countries – leaders of the innovative development. The reasons of its underrun should be searched for in the sphere of organization of innovative process on the national level, in the state and condition of the national innovative system, and in the low effectiveness of the cooperation between universities and business. An active introduction of telecommunicational technologies can play a positive role in integration of education and business.

Implications of Pressure for Shortening the Time to Market (TTM) in Defense Projects
Authors: Frank Moti , Carmi Boaz
Published: June 2014

In recent years, government and prime contractors have been expressing a growing demand, requesting that their defense R&D contractors shorten the Time To Market (TTM). This paper presents a study aimed at investigating whether developing systems using fast approaches is always preferable to traditional approaches. Does working according to a fast development approach ultimately shorten TTM? And if so, what are the implications of achieving this goal in relation to meeting the requirements and the planned budget? Two groups of projects, three projects in each group, were examined. The traditional, step-by-step, development strategy was chosen for the projects in the first group while for the other three projects, fast development strategies were chosen. The findings of the study show that fast development approach is not always preferable to the traditional approach. Pushing for a shorter TTM eventually caused serious budget and time overrun problems.
An Agile Project System Dynamics Simulation Model
Authors: White A. S.
Published: June 2014

This paper compares established Systems Dynamics (SD) models of software projects with models of agile development. A new minimal SIMULINK™ agile project model was created and compared to a Waterfall model of a NASA project. Results are presented to enable project managers to predict the performance of future agile project processes. The model includes the time to generate the requirements and a function to provide requirements volatility. These models show that for the same productivity and fraction of errors that are satisfactory, the overall development staff costs are similar for agile and waterfall projects and the undiscovered rework is less for the agile project. This model generally supports empirical observations that shorter time-box iterations yield a shorter overall project completion.
Towards Improved Music Recommendation
Authors: Snijders Remco , Spruit Marco
Published: June 2014

With the explosive growth of the World Wide Web and the rise of social media, new approaches in Music Recommendation evolve. The current study investigates how blogs and micro-blogs can improve the perceived quality of music recommendation. A literature review and expert interviews are conducted to identify important topics regarding (micro-) blogs and Music Recommendation. Subsequently, the prototype Songdice is built and tested in a user-evaluation. Songdice uses music blogs to recommend songs and rationalize those recommendations. The authors' results show that (micro-) blogs can improve the perceived quality of recommendations by creating trust, using personalization and exploiting the quality of music in the long tail. Additional research is required to determine the most effective way to use information from blogs and micro-blogs. The authors' research explores a new area in music recommendation literature and provides a starting point for further research concerning the combination of (micro-) blogs and music recommendation.
Real-Time Prediction Of Hurricane Effects On Coastal Facilities
Authors: Blumberg Randolph , Pendleton Elmer , Shaw John R. , Osborn Charles
Published: June 2014

The most critical problems facing management of coastal installations during a hurricane or major cyclonic storm are safety for human life and protection of production facilities while minimizing production losses. Equivalent risks exist for coastal municipalities.

Heretofore, there has been no sound basis for decisions forced on management by these environmental extremes. A proven computer-based system is now in use providing critical predictions of environmental effects well in advance of their occurrence. This prediction system was successfully used in the Gulf of Mexico during the 1970 hurricane season for hurricanes Celia and Ella and tropical storm Felice.

INTRODUCTION

During the Fall of 1969, The Dow Chemical Company, Texas Division (Dow) engaged the" American Science & Engineering Company (AmSEC) to determine the feasibility of developing a real-time system to provide hurricane effects predictions to minimize the losses due to hurricanes such as amille of 1969, should they approach the Freeport area. Initially, there as reservation as to the practicality f developing a prediction system which could provide management with forecasts far enough in advance to assist in decision making. The various hindcast systems used heretofore were generally time consuming and unwieldy.

The feasibility study indicated that such a system could be developed. A contract was subsequently awarded AmSEC to develop it. The contract effort yielded a prediction system which was not only practical and powerful but also economical to operate. The system pas actually proven to be even faster than anticipated.

DEFINITION OF PROBLEM

Billions of dollars worth of industrial and community properties along the northern coast of the Gulf of Mexico are exposed to possible severe damage or loss, every time a major hurricane moves across the open waters of the Gulf. The degree of risk to this massive investment is to a large extent a function of the accuracy and timeliness of predictions of the hurricane';s future path, speed of advance, intensity, and ultimate effects on coastal and offshore facilities. For many installations, particularly petro-chemical plants, it is critical to make a decision as to whether or not to shut down the plant, sometimes more than 24 hours before high winds reach the facility. Unnecessary plant shutdowns may result in millions of dollars of lost production; however, failure to act in time should a severe hurricane move near the plant, may produce serious hazards to life and result in a far greater loss due to uncontrolled shutdownsof various processes. Similarly an equivalent lack of proper action by a community can be disastrous.

New federal regulations for offshore oil and gas production make losses resulting from unnecessary shutdowns unrecoverable. This places special emphasis on the quality of hurricane risk predictions. Daily losses may run $500,000 per day for major offshore operators.

Published: June 2014

The mitochondrial genome is widely studied in a variety of fields, such as population, forensic, and human and medical genetics. Most studies have been limited to a small portion of the sequence that, although highly diverse, does not describe the total variability. The arrival of modern high-throughput sequencing technologies has made it possible to investigate larger sequences in a shorter amount of time as well as in a more affordable fashion. This work aims to describe a protocol for sequencing and analyzing the complete mitochondrial genome with the Ion PGM™ platform. To evaluate the protocol, the mitochondrial genome was sequenced to approximately 210 Mbp, with high-quality sequences distributed between 12 samples that had an average coverage of 1023× per sample. Several variant callers were compared to improve the protocol outcome. The results suggest that it is possible to run up to 120 samples per run without any loss of any significant quality. Therefore, this protocol is an efficient and accurate tool for full mitochondrial genome analysis.
Effect of FTO Gene and Physical Activity Interaction on Trunk Fat Percentage Among the Newfoundland Population
Authors: Payne Anthony , Cahill Farrell , Sun Guang , Loredo-Osti J Concepción , Abarin Taraneh
Published: June 2014

Objective

To explore the effect of FTO gene and physical activity interaction on trunk fat percentage.

Design and Methods

Subjects are 3,004 individuals from Newfoundland and Labrador whose trunk fat percentage and physical activity were recorded, and who were genotyped for 11 single-nucleotide polymorphisms (SNPs) in the FTO gene. Subjects were stratified by gender. Multiple tests and multiple regressions were used to analyze the effects of physical activity, variants of FTO, age, and their interactions on trunk fat percentage. Dietary information and other environmental factors were not considered.

Results

Higher levels of physical activity tend to reduce trunk fat percentage in all individuals. Furthermore, in males, rs9939609 and rs1421085 were significant (α = 0.05) in explaining central body fat, but no SNPs were significant in females. For highly active males, trunk fat percentage varied significantly between variants of rs9939609 and rs1421085, but there is no significant effect among individuals with low activity. The other SNPs examined were not significant in explaining trunk fat percentage.

Conclusions

Homozygous male carriers of non-obesity risk alleles at rs9939609 and rs1421085 will have significant reduction in central body fat from physical activity in contrast to homozygous males of the obesity-risk alleles. The additive effect of these SNPs is found in males with high physical activity only.

Published: June 2014

We investigate the relations between a macroscopic Lighthill-Whitham and Richards model and a microscopic

model for traffic flow. Solutions to the microscopic model are proved to tend to those to the macroscopic one in a sort of

limit, i.e. as the number of individuals tends to

+ \infty

while their total mass is constant. Based on this convergence result, we approximately compute the solutions to a conservation law by means of the integration of an ordinary differential system.

Effectiveness of Local Hemostatic Agents in Epistaxis
Authors: Hussain Tahir
Published: June 2014

Background

Epistaxis is the commonest otorhinolaryngological emergency affecting up to 60% of the population in their lifetime with 6% requiring medical attention.

Objective

The aim of this study was to find out the epidemiological profile of epistaxis in our area and to find out the effectiveness of various available eight treatment options.

Materials and methods

This study was conducted to describe the etiological profile and treatment outcome of epistaxis. This was a prospective study of the cases of epistaxis from July 2012 to May 2013. Till date, the data regarding the management of epistaxis in our setting was not available. The purpose was to evaluate the clinical and management options for epistaxis in our settings.

Results

A total of 100 patients with epistaxis were studied. Males were affected twice more than the females (2.6:1). Their mean age was 48.63 years (4-82 years). The commonest cause of epistaxis was idiopathic (33%) followed by trauma (21%) and hypertension (18%). Nonsurgical measures, such as light packing with cotton gauze soaked with local hemostatic (hemocoagulase) and antiseptic/antibiotic (36%), silver nitrate cauterization 20 (16%) and anterior nasal packing (15%) and observation alone (11%) were the main intervention methods in 78% of cases. Surgical measures mainly intranasal tumor resection was carried out in 3% of cases.

Conclusion

The most common etiological factor for epistaxis is idiopathic. Most cases were successfully managed with conservative treatment alone and surgical intervention may not be necessary in most cases and should be the last resort.

Oral squamous cell carcinoma is the 8th most common cancer worldwide and found particularly in low income communities and mainly a problem of older men, 90% being in the 45-year-age group. Histologic grading has been used as a prognostic factor and for clinical evaluation of OSCC for the past several decades. At the same time, the prognostic value of different grading classification remains controversial. So, in this article, we have reviewed the different grading system of oral squamous cell carcinoma and their prognostic value.

Antihistamines in Clinical Dentistry offering a Choice for Second Possibility in Reported Cases of Allergy to Local Anesthetics: Report of Two Cases and Literature Review
Authors: Khaji Shahanavaj Imam Husen
Published: June 2014

Drug allergy encompasses a spectrum of immunologically mediated hypersensitivity reaction with varying mechanisms and clinical presentation. Type of adverse drug reaction not only affects patient's quality of life, but may also lead to delayed treatment, unnecessary investigations and even mortality.

The most effective strategy for the management of drug allergy is the avoidance or discontinuation of the offending drug. When available, alternative medications with unrelated chemical structures should be substituted. Patients who presents with history of allergy to local anesthetics are common in dental practices. In the present report, retrospective documented history of allergy to local anesthetics (lidocaine) in two patients (50 years/female, 35 years/male) were evaluated critically and needful dental treatment procedures were carried out using antihistamines pheniramine maleate: 22.75 mg/ml; DPH HCl: 1%) as local anesthetic agents. In both the cases, antihistamines proved to be beneficial, effective, devoid of complications.

In conclusion, use of antihistaminic drugs in patients with documented history of allergy could be an alternative drug of choice having local anesthetic properties for minor dental treatment procedures in routine dental practice.

Structural Reinforcement and Sealing Ability of Temporary Fillings in Premolar with Class II MOD Cavities
Authors: Bello Yuri Dal , Barbizam João Vicente , Rosa Vinicius
Published: June 2014

Aim

To evaluate the capability to reinforce tooth structure and sealing ability of temporary filling materials in premolars with MOD cavities. The hypothesis is that temporary filling materials can concomitantly prevent microleakage and increase fracture resistance.

Materials and methods

Premolars received root canal treatment and MOD cavities. Cavities were restored with noneugenol cement (CIM), glass ionomer cement (GIC) or light curable composite (BIO). Higid and without restoration were controls. Materials for flexual strength and teeth were tested for microleakage and compressive strength.

Results

GIC and Higid presented similar compressive strength, higher than other groups. Bio and GIC presented similar flexural strength higher than BIO. CIM and BIO showed similar microleakage lower than GIC.

Conclusion

The hypothesis was rejected as filling materials tested failed to prevent microleakage and to increase fracture resistance concomitantly.

Clinical significance

GIC may be considered to restore weakened teeth subjected to occlusal loads. BIO and CIM are better choices to microleakage in teeth not subjected to mechanical stresses.

Published: June 2014

Macrodontia is a rare dental anomaly which consists on the presence of any tooth or teeth larger than the average. In the present report the case of a child with an uncommon true isolated macrodontia of a maxillary central incisor is presented. The maxillary left central incisor was considered a macrodontic tooth since its mesiodistal crown dimension was 12.41 mm while the mesiodistal crown dimension of the maxillary right central incisor was 10.06 mm. The radiographic examination confirmed an enlarged maxillary left central incisor and a normal developing dentition. The patient did not report esthetic complaints, however, due the presence of anterior open bite and crowding, he was referred to orthodontic clinic. Thus, it must be point out the importance of the radiographic diagnosis to support the clinical findings, helping to plan and provide better treatment for the patient.

Published: June 2014

Aim

To present the clinical findings of a patient with Fibrodysplasia Ossificans Progressiva (FOP), highlighting peculiarities of dental treatment in patients with this condition.

Background

FOP is a rare genetic disease characterized by skeletal malformations and ectopic ossifications in skeletal muscles, tendons, ligaments and aponeurosis. Exacerbation of these ossifications can be caused by dental treatment, resulting in disease progression.

Case description

A 26-year-old male patient with a diagnosis of FOP was referred to our service for dental treatment. The patient presented decreased mobility in peripheral joints (knees and elbows), postural disability (ankylosis of the vertebral column), lateral deviation and shortness of the hallux, as well as heterotopic ossifications on the hands and back. The implementation of conservative dental procedures, such as oral hygiene instructions and recurrent topical fluoride applications, were performed in addition to endodontic and restorative treatments. Brief dental appointments were conducted without using regional anesthesia or dental dam clamps. The dental chair was positioned at 45° to provide more comfort and to avoid exacerbating the disease. The patient has now completed 6 months of follow-up and is free of heterotopic ossifications resulting from dental treatment.

Conclusion

The dental treatment modifications implemented for the present case were sufficient to establish good oral health and to prevent the formation of heterotopic ossifications in the maxillofacial region.

Clinical significance

FOP is a rare disease dentists must familiarize themselves with to provide adequate, personalized treatment, which minimizes traumas that may exacerbate the disease.

Oral Cytokeratins in Health and Disease
Authors: Ganavi BS
Published: June 2014

The dynamics of oral mucosa is known by its inherent defensive nature. Certain areas demand tough shield when subjected to mechanical insults. This is met by structural scaffolding material referred as cytoskeleton comprised of intracellular protein filaments called cytokeratins in the surface squames of oral epithelia. They also equally contribute towards the architecture of odontogenic apparatus and salivary gland. Differentiation of epithelial cells within stratified epithelia regulates the expression of specific keratin gene. Any mutation in, or autoantibodies to keratins, desmosomal and cornified envelope proteins is translated into genetic and acquired human disorders. Sound knowledge of structural proteins, their expression, distribution and function plays a vital role in acquainting with these disorders and their application as differentiation markers. Thus, they form an integral aid in diagnostic pathology and may be instrumental in the future interventions by gene therapy. This review focuses on basics to current updates on oral cytokeratins with an emphasis on the genetic and acquired disorders of cytokeratins with oral implications.

Objectives: The aim of this study was to characterize the public health emergency perceptions and willingness to respond (WTR) of hospital-based pediatric staff and to use these findings to propose a methodology for developing an institution-specific training package to improve response willingness.Methods: A prospective anonymous web-based survey was conducted at the Johns Hopkins Hospital, including the 180-bed Johns Hopkins Children’s Center, between January and March 2009. In this survey, participants’ attitudes/beliefs regarding emergency response to a pandemic influenza and a radiological dispersal device (RDD or “dirty bomb”) event were assessed.Results: Of the 1,620 eligible pediatric staff, 246 replies (15.2 percent response rate) were received, compared with an overall staff response rate of 18.4 percent. Characteristics of respondent demographics and professions were similar to those of overall hospital staff. Self-reported WTR was greater for a pandemic influenza than for an RDD event if required (84.6 percent vs 75.1 percent), and if asked, but not required (74.4 percent vs 64.5 percent).The majority of pediatric staff were not confident in their safety at work (pandemic influenza: 51.8 percent and RDD: 76.6 percent), were far less likely to respond if personal protective equipment was unavailable (pandemic influenza: 33.5 percent and RDD: 21.6 percent), and wanted further pre-event preparation and training (pandemic influenza: 89.6 percent and RDD: 82.6 percent). The following six distinct perceived attitudes/beliefs were identified as having institution-specific high impact on response willingness: colleague response, skill mastery, safety getting to work, safety at work, ability to perform duties, and individual response efficacy.Conclusions: Children represent a uniquely vulnerable population in public health emergencies, and pediatric hospital staff accordingly represent a vital subset of responders distinguished by specialized education, training, clinical skills, and disaster competencies. Even though the majority of pediatric hospital staff report WTR, nearly 15 percent for a pandemic influenza emergency and 25 percent for an RDD event would not respond if required. Other institutions can apply the methodology used here to identify particularly influential response willingness modifiers for pediatric care providers. These insights can inform customized preparedness training for pediatric healthcare workers, through identification of high-impact attitudes/beliefs, and training initiatives focused on addressing these modifiers.
The public health impact of tsunami disasters
Authors: Keim, MD Mark E.
Published: June 2014

Tsunamis have the potential to cause an enormous impact on the health of millions of people. During the last half of the twentieth century, more people were killed by tsunamis than by earthquakes.1 Most recently, a major emergency response operation has been underway in northeast Japan following a devastating tsunami triggered by the biggest earthquake on record in Japan. This natural disaster has been described as the most expensive in world history.2 There are few resources in the public health literature that describe the characteristics and epidemiology of tsunamirelated disasters, as a whole. This article reviews the phenomenology and impact of tsunamis as a significant public health hazard.
