-The clinical use of the cuffed oropharyngeal airway (COPA)-

BACKGROUND AND OBJECTIVES: Family physicians and other primary care providers play a pivotal role in preventing oral disease, especially among minority and underserved populations who have limited access to dental services and poorer oral health status. Oral diseases/conditions, such as caries, baby bottle tooth decay, gingivitis, periodontitis, oral pharyngeal malignancies, and orofacial trauma, are prevalent and costly, yet largely preventable. Given their role in promoting and protecting overall health and their historical role in serving minority and underserved families, family physicians occupy a unique position to assure equity, access, and improvement in oral health for all Americans.     

Energetic cost of hovering flight in a nectar-feeding bat measured with fast-response respirometry

BACKGROUND: Given the high occurrence of oral manifestations in patients infected with human immunodeficiency virus (HIV), the relative ease in recognizing these manifestations on physical examination, and their potential impact on the health care and quality of life in these patients, it is critical to provide adequate training for primary care physicians in this area. METHODS: Based on a review of the published literature and the consensus of a national panel of primary care physicians and dentists with clinical and research expertise in this area, a core curriculum was developed for primary care physicians regarding oral health care issues in HIV disease. RESULTS AND CONCLUSIONS: We describe the process of developing the core curriculum of knowledge, skills, and attitudes regarding oral health care issues in HIV disease. The final curriculum is in a format that allows for easy accessibility and is organized in a manner that is clinically relevant for primary care physicians.     

Application of heparin-coated PCPS for traumatic cardiac rupture: report of a case

OBJECTIVES: This study examined whether primary care physicians provide education and counselling on head injury prevention as part of their routine health care discussions with patients. METHODS: A preventive health care practices survey was distributed to 678 physicians in the Central Virginia area. Data regarding respondents' age, gender, medical specialty, patient population and counselling practices were obtained. RESULTS: Fifty-one per cent of those surveyed responded. Ninety-five per cent of physicians reported providing health care counselling 'in most cases' or 'commonly'. Less than half (46%) of physicians discussed head injury prevention with their patients. In contrast, almost all respondents (97%) discussed smoking. Physician age, specialty, and patient population did not affect head injury counselling practices. CONCLUSIONS: Prevention strategies for head injury are discussed much less frequently than other health risks such as heart disease and cancer in the primary care setting. Strategies for educating primary care physicians on head injury should be considered in order to increase their efforts toward prevention.     

Identification of caries risk children and prevention of caries in pre-school children

A special model for dental care in pre-school children was used in a small clinic in the county of Blekinge in southern Sweden. The model is based on screening of caries risk performed by a dental assistant before the caries attack. Any single risk factor or risk behavior in pre-school children was considered. The aim was to 1) evaluate the dental assistant's selection of caries risk children up to the age of three years, 2) compare dental health variables in 4 yr olds in the test clinic with those for the whole county in 1994 and 3) compare time spent by the dentist and the dental assistant in the test clinic and in the whole county per child up to the age of four. 102 children participated. One specially trained dental assistant screened all children using background factors combined with clinical examinations at ages 1, 2 and 3. Eighty-two children participated each year from one year. A systematized form for questioning the parents was used. Individual caries prevention was given including fluoride and antimicrobial treatments as well as fissure sealants in primary molars at caries risk. The proportion of children with caries lesions at four years and a caries risk assessment up to the age of two was 1.0 (sensitivity). The proportion of children with no caries lesions at four years and no caries risk assessment at year two was 0.7 (specificity). The most frequent risk factors found at 2 yrs were frequency order: lack of oral hygiene (visible plaque), deep fissures in molars and frequent intakes of sweet drinks. The proportion of children with no caries lesions at 4 yrs of age in the test clinic was 92.9% compared to a county mean of 76.4%. In the group of children where a risk assessment was made each year from one year the proportion of caries free children was 96.3%. The total time spent per child in the test clinic was 22 minutes more than the county mean. However, dentist's time, excluding assistance, was 28 minutes less in the test clinic. The results suggest that the model used for caries prevention in pre-school children is cost-effective, and that dental health can be remarkably improved.     

Women's oral health awareness and care-seeking characteristics: a pilot study

The authors designed a pilot study to examine issues that affect women's oral health. They found a substantial lack of awareness regarding important oral health issues, and that 44 percent of the participants reportedly did not have regular dental care. High perceived dental need was reported concurrently with low dental care attendance. Additionally, reported lack of dental insurance and self-perception of low income and of poor dental health were important explanatory factors for the women who reportedly did not have regular dental care.     

Improving the professional self-efficacy cognitions of immigrant doctors with Balint groups

The City of North York Public Health Department (NYPHD) operates a school-based dental programme that provides preventive and treatment services to children according to evidence-based practice guidelines. This programme and private dental practices (PDP) represent the only sources of dental care for children in North York. The purpose of our study was to compare the oral health and family characteristics of clients from the NYPHD and PDP using a dental examination and a parent interview. Results showed that NYPHD and PDP clients had similar levels of fluorosis, calculus, and periodontal health, but NYPHD clients had experienced greater levels of decay. Clients of the NYPHD and PDP also had significantly different family characteristics, many of which were significantly associated with the presence of one or more decayed primary or permanent teeth. Multivariate logistic regression identified mother's immigration history, past caries experience, and parents' rationale for scheduling their child's dental appointments as the principle risk makers for dental decay. When compared with PDP clients, the NYPHD serves higher-needs children who otherwise might not receive care.     

The efficacy and safety of dorzolamide as adjunctive therapy to timolol maleate gellan solution in patients with elevated intraocular pressure. Additivity Study Group

OBJECTIVES: To investigate the incidence of rehardening of caries lesions in children in Southern China taking part in a preventive programme. DESIGN: Longitudinal study. SAMPLE AND METHODS: A prevention programme was established for 168 3-6-year-old children in a kindergarten (KG1), which included regular oral health education sessions and a daily toothbrushing exercise using fluoridated toothpaste (1000 ppm F). A group of 121 children studying in two other kindergartens without a preventive programme formed the controls. Due to lack of resources and dental personnel, restorative and other curative treatments were not provided. RESULTS: Rehardening of dentine caries (arrested caries) was found in children in both test and control groups. At the third annual examination, 45% of the caries lesions on the proximal surfaces of primary anterior teeth in KG1 children found at the baseline and previous annual examinations had become arrested. A multiple linear regression analysis indicated that baseline ds score and its interactions with the prevention programme, gender and the child's oral hygiene all had significant effect on the number of tooth surfaces with arrested caries at the third annual examination. CONCLUSION: Results from this study support the use of simple prevention programmes to stabilize the caries situation in communities where intensive use of trained dental personnel is not feasible.     

Evaluation and treatment of urinary tract infections in children

Urinary tract infections (UTIs) are among the most common bacterial infections encountered by primary care physicians. Although UTIs do not occur with as great a frequency in children as in adults, they can be a source of significant morbidity in children. For reasons that are not yet completely understood, a minority of UTIs in children progress to renal scarring, hypertension and renal insufficiency. Clinical presentation of UTI in children may be nonspecific, and the appropriateness of certain diagnostic tests remains controversial. The diagnostic work-up should be tailored to uncover functional and structural abnormalities such as dysfunctional voiding, vesicoureteral reflux and obstructive uropathy. A more aggressive work-up, including renal cortical scintigraphy, ultrasound and voiding cystourethrography, is recommended for patients at greater risk for pyelonephritis and renal scarring, including infants less than one year of age and all children who have systemic signs of infection concomitant with a UTI. Antibiotic prophylaxis is used in patients with reflux or recurrent UTI who are at greater risk for subsequent infections and complications.     

Prevention of violence

Primary care physicians can easily incorporate efforts toward the primary and secondary prevention of family violence into their practices. By designing a preventive effort using the phases of the family life cycle, a developmentally appropriate system of prevention is created. The anticipatory guidance at each (annual) visit acknowledges family transitions and assures the family that abuse is a health issue and that the physician is a resource for issues of violence prevention. Using the FLC, the first phase is Coupling, when there is a risk of partner violence that continues as long as there is a partnership. Pregnancy and childbirth bring concerns of child neglect and battery. Older children are at additional risk for child sexual abuse. As families age, risks develop for elder abuse, too. The regular discussion of these issues raises the awareness that the potential for family violence continues over the life span and allows the physician opportunities to assess the risk of violence in that family and make appropriate preventive referrals. Primary care physicians are optimally positioned to address violence and its prevention in the office: they know and care for family units over time. Physicians are respected and trusted advisors who can become effective in preventing violence.     

Preparing for the "silver age of dentistry"

Providing oral health care to older adults will be a challenging and rewarding part of dental practice in the years ahead. It will include understanding normal aging, appreciation of the pathophysiology of chronic diseases experienced by many elderly, and application of key principles of pharmacology in care of patients receiving medications for treatment of these diseases. It will involve an understanding of the interaction of systemic conditions with oral health status, adequate diagnosis of oral disease, and appropriate rational treatment planning with a strong emphasis on preventive dentistry. It will include care provided in nursing homes or during housecalls for the homebound. Dentist-geriatricians will be working with teams of healthcare professionals that include physicians, dentists, podiatrists, ophthalmologists, nurses, social workers, nutritionists, pharmacists, and occupational and physical therapists. Above all, the team will provide skilled compassionate care, which is always good business!     

5-Hydroxytryptamine, angiotensin and bradykinin transiently increase intracellular calcium concentrations and PKC-alpha activity, but do not induce mitogenesis in human vascular smooth muscle cells

Primary care physicians have an important role in coronary heart disease prevention. This paper discusses the results of a qualitative study conducted with Nova Scotian physicians to explore the following: physicians' expectations about their role in prevention; obstacles to providing preventive care; and, mechanisms by which preventive care occurs. The second part of the paper presents a practice model which is intended as a framework by which physicians may more effectively educate and counsel their patients about health issues, such as coronary heart disease.     

Diffusion of digital radiology modalities in the Nordic countries and Japan

The Nordic countries have 23 million inhabitants. About 14 million radiology examinations are performed annually at hospitals and in primary health care. This represents about 600 examinations per 1000 inhabitants per year. Japan, on the other hand, has 125 million inhabitants and annually performs about 200 million radiology examinations at hospitals and in primary health care. This represents about 1600 examinations per 1000 inhabitants per year. The above figures do not include dental X-ray examinations. Between 15% and 20% of all radiology examinations in the Nordic countries and about 5% in Japan are performed with digital modalities such as computerized tomography, digital subtraction angiography, computed radiography, and magnetic resonance imaging. Computerized tomography is the most diffused digital X-ray modality in the Nordic countries with 95,000 inhabitants per scanner while Japan only has 17,000 inhabitants per scanner. For magnetic resonance imaging the difference is almost of the same order. Japan has the same diffusion of magnetic resonance imaging units per 100,000 inhabitants as the Nordic countries have of computerized tomography scanners. The large difference between Japan and the Nordic countries regarding diffusion of digital radiology modalities is explained mainly by differences in the nature and organization of radiology services.     

Angiocardiographic digital still images compressed via irreversible methods: concepts and experiments

OBJECTIVE: Primary care occupies a strategic positive in the evaluation, treatment, and prevention of the mental disturbances of later life. This article highlights four themes that are crucial to understanding mental disturbances among older adults: 1) subsyndromal depression, 2) coexisting depression and anxiety, 3) comorbidity of depression and chronic medical conditions, and 4) risk factors for cognitive impairment. METHOD: The literature was selectively reviewed for each theme to ask the central question, "What can primary care physicians learn about mental disturbances of their older patients from epidemiologic and community studies?" RESULTS: The primary care setting itself is an important venue for an examination of aging issues and mental health. Workers in the "middle ground of psychiatric epidemiology"--primary health care--have not yet reached a full appreciation for the value of research in the primary care setting for enhancing our understanding of the mental disturbances of late life, and how these intersect with other salient factors. CONCLUSIONS: Primary care physicians and others who work in primary care should advocate for further mental health integration and research in primary care. Research is needed that will lead to new ways of maximizing the health and quality of life of older adults and their families.     

The INSURE project on lifecycle preventive health services

The INSURE Project on Lifecycle Preventive Health Services is a 3-year study to determine the feasibility of implementing preventive services in primary medical care as a health insurance benefit and to assess the short-term impact of this implementation on providers and consumers. Initiated by the life and health insurance companies, the project has received additional support from private philanthropic foundations. Preventive services, which will be provided under a lifecycle approach according to the age and sex of the patient and include education of patients on health-related behavior, will range from prenatal care through geriatrics. A quasi-experimental design will be used in which three study (experimental) group practice sites are matched with three control group practice sites. At the study sites, the primary care physicians will participate in orientation sessions on recommended preventive services and patient education procedure; they will also examine and counsel the study patients. The study and control physicians and patients will be surveyed before and after the program of intervention is conducted at the study sites to assess their knowledge, attitudes, and behavior toward health behavior practices.     

An overview of dental care for the young patient: 1. Introduction, priorities and disease prevention

The provision of high-quality dental care for children presents a challenge for the general dental practitioner. The aim must be to ensure that young patients reach adulthood with optimal dental health. This series of three articles takes an overview of good practice in the provision of dental care for children, with emphasis on disease prevention, early diagnosis of dental disease and deformity and appropriate treatment measures. This first paper discusses preventive measures and highlights the need to apply them, particularly for patients at high risk of dental disease or with special needs in relation to dentistry.     

Fundus autofluorescence in patients with macular holes imaged with a laser scanning ophthalmoscope

BACKGROUND: Because of a strong association between health maintenance visits (HMVs) and cancer screening, knowledge of the predictors of an HMV have implications for screening. OBJECTIVE: To examine the association of an HMV with patient, physician, and practice characteristics in the primary care setting. DESIGN: A statewide study of cancer screening was conducted in Colorado to determine concordance with the National Cancer Institute's guidelines for screening for breast, cervical, prostate, and skin cancer. Medical records form patients were randomly chosen from primary care practices. Predictors of an HMV were determined by fitting a logistic model to baseline data, adjusting for the cluster sampling of patients within practices. SETTING: Nonacademic primary care practices in Colorado. PARTICIPANTS: A total of 5746 patients aged 42 to 74 years from 132 primary care practices. MAIN OUTCOME MEASURE: Whether a patient had an HMV in the previous year. RESULTS: Of all patients, 31% had an HMV in the previous year. Patient characteristics associated with having HMVs included nonsmoking status, odds ratio (OR) (95% confidence interval [CI]) of 1.27 (1.11-1.46), age, and sex. Women aged 50 to 69 years were significantly more likely to have an HMV than men aged 50 to 69 years (OR, 1.30; 95% CI, 1.10-1.54). Among adults aged 70 years and older, there were no significant sex differences in receiving HMVs. Physician and practice characteristics associated with providing HMVs included practice size (> or = 3 full-time physicians) (OR, 1.34; 95% CI, 1.01-1.77), physician contemplation of changing approaches to cancer screening (OR, 1.33; 95% CI, 1.04-1.70), and physician female sex (OR, 1.33; 95% CI, 1.04-1.70). Physician age and specialty (general internist or family physician) were not associated with the level of health maintenance delivery. CONCLUSION: Certain subgroups, such as smokers, patients in smaller practices, and physicians not yet considering changing their approach to cancer screening, could be targeted in future intervention studies designed to provide preventive services in primary care settings.     

The role of the primary care physician in the care of children with serious heart disease

OBJECTIVE: To determine the roles of primary care physicians and specialists in the medical care of children with serious heart disease. SETTING: Pediatric Cardiology Division; Tertiary Care Children's Hospital. SUBJECTS: Convenience sample of parents, primary care physicians, and pediatric cardiologists of 92 children with serious heart disease. DESIGN: Questionnaire study; questionnaires based on 16 medical care needs, encompassing basic primary care services, care specific to the child's heart disease and general issues related to chronic illness. RESULTS: All children had a primary care physician (PCP), and both they and the parents (P) reported high utilization of PCP for basic primary care services. However, there was little involvement of PCP in providing care for virtually any aspect of the child's heart disease. Parents expressed a low level of confidence in the ability of PCP in general or their child's own PCP to meet many of their child's medical care needs. Both PCP and pediatric cardiologists (PC) were significantly more likely than parents to see a role for PCP in providing for care specific to the heart disease as well as more general issues related to chronic illness. PC and PCP generally agreed about the role PCP should play, although PC saw a bigger role for PCP in providing advice about the child's activity than PCP themselves did. PC were less likely to see the PCP as able to follow the child for long term complications than PCP did. PC were more likely than PCP to believe that PCP were too busy or were inadequately reimbursed to care for children with serious heart disease. Only about one-third of parents reported discussing psychosocial, family, economic, or genetic issues with any provider, and PCP were rarely involved in these aspects of chronic illness. CONCLUSIONS: Primary care physicians do not take an active role in managing either the condition-specific or the more general aspects of this serious chronic childhood illness. With appropriate information and support from their specialist colleagues primary care physicians could provide much of the care for this group of children. Generalists and specialists are both responsible for educating and influencing parents about the role primary care physicians can play in caring for children with serious chronic illness.     

A survey of general dentists in Ontario, Part II: Knowledge and use of topical fluoride and dental prophylaxis practices

A mail questionnaire was used to assess variations in the knowledge and practices of Ontario dentists with respect to topical fluoride and prophylaxis procedures. The questionnaire was answered by 1,276 general dentists. A high percentage (72 to 83 per cent) of respondents identified six months as the optimal time interval at which both procedures should be repeated for all patients under 19 years of age. Relatively few dentists (< 10 per cent) indicated that there should be no specific time interval for re-treatment (i.e. that it should be individually selected). The respondents' preventive knowledge was found to be deficient in two areas: few dentists (16 per cent) knew that it is not necessary to provide a prophylaxis prior to topical fluoride application to achieve maximum caries protection; and most dentists overestimated the speed of caries progress from outer enamel to the dentinoenamel junction (DEJ) in both primary (83 per cent) and permanent (82 per cent) approximal tooth surfaces. In bivariate analysis, three variables were found to be consistently and significantly related to optimal time intervals selected for both topical fluoride application and prophylaxis procedures: year of graduation from dental school; level of hygienist employment; and percentage of patients with private insurance. Multivariate analysis also identified three significant variables: year of graduation from dental school; level of dental hygienist employment; and practice business. Continuing education courses are suggested as a means of updating dentists' knowledge regarding preventive services. Studies are needed to determine the extent to which recent recommendations regarding the professional application of topical fluorides have been followed.     

Shared management of children with cancer

OBJECTIVE: To determine the risks and benefits of university-based pediatric oncologists and community-based primary care physicians sharing the management of children with cancer. DESIGN: Physicians participating in shared management of children with cancer were surveyed, and the outcomes of the children were measured. SETTING AND PARTICIPANTS: One hundred thirty-seven community-based primary care physicians participated in the management of the 226 children with cancer in Iowa and western Illinois during the past 15 years. The survival of the 226 children was compared with that of 240 randomly selected children treated using the identical treatment protocols but treated only by pediatric oncologists. INTERVENTION: A 7-point Likert scale questionnaire was completed by 97 (71%) of the participating primary care physicians. RESULTS AND OUTCOME MEASURES: There were no differences in the survival of children using shared management compared with those treated only by pediatric oncologists. Primary care physicians believed that shared management is of economic and psychosocial benefit to patients, improves the treatment choices available to patients, does not require excessive time, and does not result in loss of practice income. The system strengthens the primary care physicians' relationships with oncologists and results in additional referrals to the university-based pediatric oncologists. It is of educational value, is personally satisfying, and provides relief from the stress associated with caring for these families. Primary care physicians would like to see this system expanded to include other children with special health care needs. CONCLUSION: The shared-management approach to care is a viable attractive option of health care provision for children.     

What physicians should currently observe in the area of dental health

Several factors govern the development of human dental caries. The actual caries incidence in children depends greatly on fluoride consumption, reduction of fermentable sugar intake (in favour of the use of sugar substitutes), dental health habits and regular dental check-ups. A significant reduction of dental caries in children and young adults is achieved in many countries following these principles. However, there remains a group, about 25%, with a particularly high incidence of caries. Today, efforts are directed at detecting these risk subjects. Mutans streptococci and lactobacilli are the main causative bacteria of human dental caries. The initiation of dental caries is preceded by colonisation of the dentition by S. mutans, usually in early childhood. The early establishment of these bacteria in the mouth of human infants is dependent on intrafamilial--mainly maternal--transmission of saliva. The higher the level of S. mutans in the maternal saliva, the more likely is the colonisation of primary dentition by cariogenic bacteria. The earlier the colonisation, the higher the incidence of caries. Today we have new diagnostic aids: Simple microbiological tests to detect the individuals with high salivary levels of these cariogenic bacteria, so called SM-millionaires. The tests are also a good educational aid for motivating patients to individual prophylaxis. What could a paediatrician or gynaecologist do to help the dentist? He could inform the parents early enough to avoid saliva contacts. For example, the mother should not take the child's spoon or pacifier in her mouth. The dentist meets the children much later, at an age where they already have caries. The older methods, mentioned at the begin, are also still valuable.
