The management of common and uncommon problems following breast augmentation can pose a challenge in some situations. The diversity of these problems is remarkable and different principles and concepts should be adhered to for optimal management. This article reviews some of these problems and hopefully provides solutions for prevention and ...

On 20 July 2006, the Far North District Council resolved to fluoridate Kaitaia and Kaikohe. This was the first such initiative by any Territorial Local Authority (TLA) in New Zealand for 23 years, and resulted from a fluoridation advocacy programme. This paper describes the programme implementation, assesses its consistency with ...

The concepts of chain graph, general graph, and complete graph have been used to implement the graph framework of molecular connectivity (MC) theory. Some concepts of this theory have been addressed using "external" theoretical concepts belonging mostly to quantum or structural chemistry, with no direct counterpart in graph theory. Thus, ...

Although there is a body of evidence suggesting beneficial effects of premarital prevention, little research directly examines the mechanisms of effect. One study that examined changes in communication following training in the Prevention and Relationship Enhancement Program (PREP) found that, although couples made the expected communication gains pre to post ...

The aim of this paper was to critically review the current role of community water fluoridation in preventing dental caries. Original articles and reviews published in English language from January 2001 to June 2006 were selected through MEDLINE database. Other sources were taken from the references of the selected papers. ...

Diarrhoea is a common complication of antimicrobial therapy. The term antibiotic-associated diarrhoea (AAD) is often considered synonymous with Clostridium difficile. In fact, AAD can develop through a variety of mechanisms and manifest through a broad range of clinical signs and symptoms. For improved prevention and recognition of AAD, it is ...

Tetrodotoxication was observed in six patients who ate gastropods from the South China Sea near Pratas Island. The pathogenic gastropod was Nassauris glans, which had not been previously mentioned in human tetrodotoxication. An extremely high level of tetrodotoxin was found in the causative gastropods, and a variety of clinical signs ...

Dental caries (tooth decay) was uncommon in Pacific Island communities before European trading and migration expanded into the Region. The etiology of this oral microbial disease is a consequence of changed diets, food preparation and lifestyle. In particular, the easy availability of a high level of frequent dietary supplementation with ...

OBJECTIVE: We compared estimates of fluorosis prevalence and risk attributable to fluoridation using an index applied to the entire dentition and to the maxillary anterior teeth. We also estimated the prevalence of perceived esthetic problems attributable to current fluoridation policy (Attributable Burden). METHODS: Fluorosis prevalence estimates were obtained from the ...

The concept of minimal intervention dentistry has evolved as a consequence of our increased understanding of the caries process and the development of adhesive restorative materials. It is now recognised that demineralised but noncavitated enamel and dentine can be 'healed', and that the surgical approach to the treatment of a ...

To develop a relevant, community-based prevention campaign, the authors examined, using street-intercept interviews, syphilis-related knowledge, circulation of information, and screening and treatment practices among four hundred residents of two inner-city communities in Houston, Texas, where syphilis case rates exceed city, county, and national averages. Although awareness of syphilis was near ...

Dr Marshall Webb (1844-1883), author, lecturer, debater, clinician, inventor, and dentist extraordinaire, was a decade ahead of others in putting forth a concept of "extension for prevention." One hundred twenty years ago, he was one of the best known, most advanced, and highly regarded dentists in the world. His pioneering ...

A review and mapping of fluoride test data for 270 water sources in 126 communities and examination of the literature of fluorosis distribution in Ethiopia show that this health problem extends beyond the Rift Valley into some highland communities. Fluoride concentrations above 5.0 mg/l in the Rift Valley were found ...

The question considered in this review is the extent to which changes in the prevalence or severity of enamel fluorosis have occurred over the last half-century. Emphasis is given to a review of those studies in which subjects are drinking water that is fluoride deficient and those in which subjects ...

In order to compare the effect of beverages "imported" from nearby communities on the fluoride intake of a fluoridated community with that of a nonfluoridated community, 45 different carbonated and juice drinks were sampled from Houston (fluoridated) and San Antonio (nonfluoridated) and examined for their fluoride concentrations. In spite of ...

By the end of 1997, only 121 communities (59 percent) of the population in Massachusetts were receiving fluoridated water serving 3,523,615 people. Eleven communities, three of which are naturally fluoridated, are partially fluoridated communities. According to the 1992 Fluoridation Census. Massachusetts was ranked 35th in the nation by percentage of ...

With the aging of the American population and the endemic problem of gingival recession, patients will inevitably suffer from greater exposure of root surfaces and therefore will be more likely to develop root caries. The treatment of root caries is often frustrating. Traditional biomaterials used for the restoration of enamel ...

OBJECTIVES: This study sought to determine the prevalence of esthetic problems due to dental fluorosis, and determine the relationship of different fluoride exposure histories to the occurrence of these problems. METHODS: In 1993-94 2,715 children in grades 2 and 3 and 3,297 adolescents in grades 8 and 9 were examined ...

Our aim was to compare plaque fluoride and the level of mutans streptococci in saliva and plaque before and 1 and 2 years after discontinuation of water fluoridation in Kuopio, Finland. For comparison, a low-fluoride community was included in the study. Pooled plaque and saliva were collected from a random ...

Communal water fluoridation is not considered controversial by the vast majority of the scientific community; however, politically it has persisted as an issue that many legislators and community leaders have avoided because of an aura of dispute, it has been a battleground for vigorous opposition by a very small but ...

Meconium stained liquor (MSL) is a common problem in obstetrics, but its management at district level causes some specific questions. Recent literature was reviewed to obtain an insight in the current knowledge about the significance, the related pathology and the possible strategies to prevent adverse fetal outcome. The acquired data ...

This paper discusses several different points of view in an effort to define the elusive and often confusing concept of "self", and to differentiate it from "ego", a term which has, at times, been used synonymously with it. The concept of self is then discussed in relation to its usefulness ...

Due in part to a lack of appropriate training and the incentive of adequate compensation, preventive dentistry in the United States has focused on prophylaxis and fluoride application. Dentistry must shift its attention to developing standardized protocols for "preservative dentistry"--diagnosing caries, assessing and monitoring caries risk, arresting active caries and ...

Water fluoridation at the optimal concentration for the geographic area confers the maximum decay preventive benefits. Numerous communities have suboptimal levels of naturally occurring fluoride. The question of how much additional caries preventive benefits would be obtained if these communities fluoridate is of more than academic interest. Using Los Angeles ...

Interest among researchers in the diagnosis, aetiology, prevention, and treatment of root caries has increased substantially over the past two decades. However, there are some fundamental problems impeding the advancement of the field which remain to be addressed and resolved. A universally acceptable definition of root caries is not yet ...

Using survey data from Mexico City recorded in 1982 and 1989, the results of this paper suggest that practice-based, disease-orientated, one-to-one technical dentistry is failing to solve the problems of oral health. Prevention constitutes a much better alternative as it can be provided for a greater number of people, more ...

Every year 85,000 women die from obstructed labour and many many more lose their baby and have debilitating physical damage as a result. In this paper the extent of the problem is described. Methods by which obstructed labour can be prevented are given. Early detection and prompt referral for appropriate ...

Czech composer Leos Janácek (1854-1928) represents one of the most remarkable cases of creative energy in advancing years. Indeed, he is remembered primarily for the works that he composed in the last decade of his life. In this paper, Janácek's concept of aging is outlined in three areas: the subject ...

The results of surveys carried out between 1976 and 1985 in the fluorosis-endemic area of the Ethiopian Rift Valley is summarised, with emphasis on the neurological complications resulting from the crippling osteofluorosis. The neurological manifestations in the forms of myelopathy with and without radiculopathy (respectively 72% and 28%) occurred after ...

An increase in the number of methods of fluoride administration over and above traditional modes, while offering new caries-preventive possibilities, has also created problems. These cannot be solved by the purely scientific, objective approach, since emotional resistance to fluoride has increased in some countries in parallel to environmental pollution. In ...

Eighteen-month caries incidence among older adult residents of fluoridated and nonfluoridated communities was compared. Rates for both coronal and root caries were consistently lower among long-term residents of the fluoridated communities than among life-long residents of nonfluoridated communities. Coronal caries incidence was significantly lower for people who had resided in ...

We have argued that the concept of attributable fraction requires separation into the concepts of excess fraction, etiologic fraction, and incidence-density fraction. These quantities do not necessarily approximate one another, and the etiologic fraction is not generally estimable without strong biologic assumptions. For these reasons, care is needed in deciding ...

Six cases of cylinder problems encountered in 1986 with the AMS 700 Silastic inflatable penile prosthesis (IPP) were studied in detail. The problems included 1 case of significant penile bending, the development of a cylinder tear, and several cylinder aneurysms. Possible causes of the problems are explored, along with possibilities ...

In order to develop theory any community of scientists must agree as to what constitutes its phenomena of interest. A distinction is made between phenomena of interest and exemplars. The concept "prevention" is viewed as an exemplar, whereas the concept "empowerment" is suggested as a leading candidate for the title ...

Misoprostol is a synthetic prostaglandin which is related structurally to naturally occurring prostaglandin E1 (PGE1). PGE1 has long been recognized as an effective inhibitor of gastric acid secretion when administered intravenously. However, three major problems have prevented the use of natural PGE1 as a therapeutic treatment for peptic ulcer disease. ...

A unique illness consisting largely of quadriplegia in an 18-year-old woman with neurogenic and psychogenic seizures is described and discussed in detail. The precise nature of the illness remains obscure, although it was predominantly hysterical. The concept of hysteria is reappraised and examined in terms of the mind-brain problem of ...

The antibacterial activity of octenidine dihydrochloride (WIN 41464-2) against intact preformed in vitro plaques of four indigenous oral plaque-forming microorganisms, Streptococcus mutans, Streptococcus sanguis, Actinomyces viscosus, and Actinomyces naeslundii, was studied. Both absolute (plaque bactericidal index) and relative (chlorhexidine coefficient) indices of antiplaque efficacy were established. Octenidine dihydrochloride compared favorably ...

Theft by employees costs American businesses and their customers many billions of dollars each year. Despite concerted efforts to reduce the problem, it appears to continue to grow. Most of these efforts concentrate on limiting the opportunity to steal. However, because the motivations for theft are varied, preventing it often ...

Caries prevention with the aid of administration of fluoride in a great variety of forms has been extensively studied in the past decades. Whilst the scientific and technical problems around these preventive measures can be considered to be solved, there remains the problem of implementation not only on a community ...

In the period June 6--July 24, 1977, and outbreak of illness due to adenovirus type 3 (AV3) occurred in residents of a suburban community (Community A), Dekalb County, Georgia. Based on surveys, at least 105 cases occurred. The illness was primarily characterized by sore throat, fever, headache, and anorexia. Conjunctivitis ...

The forces involved in shaping urinary calculi reside in crystalline characteristics and especially in local influences. Box pleves may restrict passage and, by allowing mobility, help shape a round calculus. Fixation, occurring with a rapidly growing infection stone, facilitates initial growth on a matrix mold in a funnel pelvis, further ...

Four types of fluoridated amalgam were assessed in vitro in terms of fluoride release, corrosion behaviour and compressive strength, and compared with amalgams prepared from the corresponding non-fluoridated alloys. Although corrosion susceptibility was found to be increased, steady release of the fluoride ion was demonstrated over a 16-week period, indicating ...

The Canadian medical staff at the 1976 Olympic Games found that muscular low back pain was a common problem among the athletes. The problem had usually developed during training as a result of neglect of certain anatomic areas, particularly the abdominal region. A five-point treatment and prevention program was used ...
