Allergic contact dermatitis in dentistry

AUSTRALASIAN JOURNAL OF DERMATOLOGY, Issue 2 2000
Diana M Rubel
SUMMARY Allergic contact dermatitis (ACD) in dentistry may affect dentists and orthodontists, technicians, nurses and patients. Changes to dental practice in recent years have altered the reported frequencies of allergens causing ACD in both dental personnel and patients. Allergic contact dermatitis to medicaments, metals and glutaraldehyde were previously common allergens in dentistry; however, widespread adoption of rubber gloves by staff has resulted in a significant increase in ACD to glove allergens in both dental staff and their patients, while affording protection against the traditional allergens. Both public concerns about potential toxicity of metals in oral restorations and a greater demand for cosmetic dentistry, have resulted in greater use of acrylics and resins by dental personnel, exposing them to highly allergenic materials. Dermatologists need to be aware of the newer allergenic materials used in dentistry in order to correctly manage skin diseases in this high-risk group. [source]


Awareness of potential valvulopathy risk with pergolide and changes in clinical practice after label change: a survey among European neurologists

EUROPEAN JOURNAL OF NEUROLOGY, Issue 6 2007
A. LLedó
In response to concern about the reported frequency of ergot-associated valvulopathy in patients with Parkinson's disease (PD), Eli Lilly and Company updated the Risk Minimization Program for pergolide, changing the Summary of Product Characteristics (SmPC) and distributing a Dear Doctor Letter (DDL) highlighting the new label changes. A survey was conducted subsequently to assess neurologists' awareness of the revised SmPC and their resulting changes in practice. A random sample of 20.3% of neurologists (n = 4056) from 12 eligible EU countries were invited to participate. Of the target population of 247 neurologists who treated patients with PD, used pergolide in 2005, and were willing to participate, 244 (99%) responded. Overall awareness of the DDL and the SmPC changes was 94.2%. Over half (58.3%) of neurologists indicated that they prescribe pergolide exclusively as second-line treatment, although some (21.9%) used pergolide exclusively as first-line treatment. In response to the DDL, most neurologists perform echocardiograms before treatment (67.5%) and during treatment (76.7%), and over half (55%) avoid prescribing doses >5 mg/day. Overall, use of a DDL to communicate an SmPC change was effective in increasing the awareness of pergolide-associated valvulopathy and in modifying neurologists' clinical practice to minimize this risk.

Achievement orientations from subjective histories of success: Promotion pride versus prevention pride

EUROPEAN JOURNAL OF SOCIAL PSYCHOLOGY, Issue 1 2001
E. Tory Higgins
A new task goal elicits a feeling of pride in individuals with a subjective history of success, and this achievment pride produces anticipatory goal reactions that energize and direct behavior to approach the task goal. By distinguishing between promotion pride and prevention pride, the present paper extends this classic model of achievement motivation. Regulatory focus theory (Higgins, 1997) distinguishes between a promotion focus on hopes and accomplishments (gains) and a prevention focus on safety and responsibilities (non-losses). We propose that a subjective history of success with promotion-related eagerness (promotion pride) orients individuals toward using eagerness means to approach a new task goal, whereas a subjective history of success with prevention-related vigilance (prevention pride) orients individuals toward using vigilance means to approach a new task goal. Studies 1,3 tested this proposal by examining the relations between a new measure of participants' subjective histories of promotion success and prevention success (the Regulatory Focus Questionnaire (RFQ)) and their achievement strategies in different tasks. Study 4 examined the relation between participants' RFQ responses and their reported frequency of feeling eager or vigilant in past task engagements. Study 5 used an experimental priming technique to make participants temporarily experience either a subjective history of promotion success or a subjective history of prevention success. For both chronic and situationally induced achievement pride, these studies found that when approaching task goals individuals with promotion pride use eagerness means whereas individuals with prevention pride use vigilance means.

Non-prescription medicine use by outpatients of a hospital in north-central Trinidad living with hypertension, and the potential clinical risks

INTERNATIONAL JOURNAL OF PHARMACY PRACTICE, Issue 5 2008
Miss Rian Extavour Assistant Lecturer, principal investigator
Objective To describe the reported use of non-prescription medicines (NPMs) and the reported frequency of use by outpatients living with hypertension; to identify potential drug-drug and drug-disease interactions between reported NPMs and either antihypertensives prescribed or hypertension. Setting Adult outpatient clinics of the Eric Williams Medical Sciences Complex Adult Hospital in Trinidad. Method Outpatients were interviewed about their use of NPMs using a structured instrument. Chi-squared test or Fisher's exact test was used to test for associations between NPM use and selected variables: age group, gender, education level, number of prescribed medicines, use of prescribed medicines and the presence of comorbidities. Combinations of NPMs and antihypertensive drugs or hypertension itself that may lead to undesirable interactions were identified. Key findings One hundred and fifty-five clients were interviewed (mean age 61 years; 46% men; 56% of East Indian descent). Of these, 82% were living with a cardiac condition and 60% with diabetes mellitus. In addition, 92% reported using NPMs to treat minor illnesses. Analgesic use was reported by 81%. Some 66% reported using paracetamol, 54% reported antitussives, 48% antacids, 47% antihistamines and 39% said they used sympathomimetic drugs. The majority (98%) of NPMs were used only when needed. Sixty per cent had at least one combination a with risk of interaction with NPMs and hypertension or antihypertensive medicines: 16% had risk of interactions between enalapril (or captopril) and antacids, 13% between angiotensin-converting enzyme (ACE) inhibitors and non-steroidal anti-inflammatory drugs (NSAIDs), 12% between beta-blockers and NSAIDs and 12% between thiazide diuretics and NSAIDs. Thirty-nine per cent had a drug-disease interaction risk due to sympathomimetic drugs and 26% had one due to NSAID use. Conclusion Based on self-reports, outpatients living with hypertension in north-central Trinidad use NPMs when needed to treat minor illnesses, mainly paracetamol for pain. Non-prescription-antihypertensive interactions may arise due to ACE inhibitor/antacid combinations and NPM-hypertension interactions may result from use of sympathomimetics. Interactions may also arise as a result of the use of NPMs containing NSAIDs and sodium. [source]


Pricing Behavior and the Response of Hours to Productivity Shocks

JOURNAL OF MONEY, CREDIT AND BANKING, Issue 7 2007
DOMENICO J. MARCHETTI
pricing behavior; technology shocks; hours Recent contributions have suggested that technology shocks have a negative impact on hours, contrary to the prediction of standard flexible-price models of the business cycle. Some authors have interpreted this finding as evidence in favor of sticky-price models, while others have either extended flexible-price models or disputed the empirical finding itself. In this paper, we estimate a variety of alternative total factor productivity measures for a representative sample of Italian manufacturing firms and on average find a negative effect of productivity shocks on hours growth. More interestingly, using the reported frequency of price reviews, we show that the contractionary effect is stronger for firms with stickier prices and weaker or not significant for firms with more flexible prices. Price stickiness remains a crucial factor in shaping the response of hours after controlling for product storability or market power. [source]


Teaching consultation skills: a survey of general practice trainers

MEDICAL EDUCATION, Issue 3 2001
Alison Evans
Background Consultation skills are vitally important in general practice (GP), and now form part of the summative assessment of GP registrars in the UK. GP trainers need to be skilled in teaching consultation skills, and also need the time and resources to ensure that their registrars are competent in consultation skills. Aims To describe the teaching methods used by GP trainers in one deanery, the frequency of teaching of consultation skills, the problems encountered and the training that GP trainers have themselves received both in consultation skills and how to teach them. Method Postal questionnaire survey of all the 164 trainers in the Yorkshire Deanery. Results Replies were received from 129 trainers (response rate 79%) of which 123 could be analysed. Of these trainers, 45 (37%) trainers taught consultation skills fewer than five times a year, 45 (37%) five to 10 times, and 14 (11%) more than 10 times a year. A total of 24 trainers reported problems with teaching consultation skills, most commonly lack of time, technical difficulties, and unreceptive registrars, and 97 (79%) trainers had had some postgraduate training in consultation skills with 112 (91%) reporting some form of teacher training. Conclusion There is considerable variation in the reported frequency of teaching consultation skills, the models used, and the preparation of trainers for teaching, despite a systematic approach to teacher training in the Yorkshire Deanery.

Cyclin D1 expression in ductal carcinoma in situ, atypical ductal hyperplasia and usual ductal hyperplasia: An immunohistochemical study

PATHOLOGY INTERNATIONAL, Issue 7 2000
Yoshihisa Umekita
The cell cycle regulatory gene, Cyclin D1, plays a critical role in the growth and progression of several types of human cancer, including breast cancer. Immunohistochemical study of Cyclin D1 expression has been extensively reported in invasive ductal carcinoma (IDC). In contrast, there have been few reports concerning Cyclin D1 expression in ductal carcinoma in situ (DCIS) and their positive rates are variable. The differences in the reported frequency may be largely due to the differences in antibodies used, immunohistochemical methods and the positive cut-off point. However, we speculated that the strictness of diagnosis of DCIS might be somewhat responsible for these differences in frequency. Therefore, we selected cases of DCIS by carefully eliminating cases of predominantly intraductal carcinoma (PIC). Moreover, to clarify whether Cyclin D1 expression is involved in multistep carcinogenesis or the progression of human breast cancer, we immunohistochemically investigated Cyclin D1 expression in 57 DCIS, 10 atypical ductal hyperplasia (ADH), 70 usual ductal hyperplasia (UDH), 44 PIC and 92 IDC. Cyclin D1 expression was detected in 41 DCIS cases (72%), 22 PIC cases (50%) and 40 IDC cases (43%). No expression of Cyclin D1 was observed in either ADH or UDH. There were no significant correlations between Cyclin D1 expression and histological grade or estrogen receptor expression in DCIS. These results suggest that Cyclin D1 expression may play an important role in the early stages of carcinogenesis, and that immunohistochemical detection of Cyclin D1 expression may be helpful in differentiating low-grade DCIS from ADH.

Takayasu arteritis: Utility and limitations of magnetic resonance imaging in diagnosis and treatment

ARTHRITIS & RHEUMATISM, Issue 6 2002
Elisa Tso
Objective Previous studies have confirmed the poor correlation of symptoms, signs, and levels of acute-phase reactants with disease activity in ,50% of all patients with Takayasu arteritis (TA). Invasive angiographic studies demonstrate vessel lumen anatomy, but do not provide qualitative information about the vessel wall. Moreover, sequential invasive angiographic studies expose patients to high-dose ionizing radiation and catheter/procedure-related morbidity. The aim of the present study was to determine the utility of new developments in vascular magnetic resonance (MR) technology in patients with TA. Methods Electrocardiogram-gated "edema-weighted" MR was used to evaluate the aorta and its primary branches with regard to the vascular lumen, vessel wall anatomy, and vessel wall edema in 24 TA patients (77 studies). Inclusion criteria were age <50 years and features of TA on both clinical examination and invasive angiographic studies. Patients were stratified based on clinical and laboratory indications of having either unequivocally active disease, inactive disease, or uncertain disease status. Results MR revealed vessel wall edema in 94% (17 of 18), 81% (13 of 16), and 56% (24 of 43) of studies obtained during periods of unequivocally active disease, uncertain disease activity, and apparent clinical remission, respectively. Westergren erythrocyte sedimentation rate and C-reactive protein values did not correlate with either the clinical assessment of disease activity or MR evidence of vascular edema. The frequency of presumed vascular inflammation (edema), as assessed by MR, in patients who appeared to be in remission was similar to the reported frequency of new angiographic lesions and histopathologic evidence of active disease in surgical specimens from patients thought to be in remission. However, the presence of edema within vessel walls did not consistently correlate with the occurrence of new anatomic changes found on subsequent studies. Conclusion Inconsistencies in the presence or absence of vessel edema and subsequent anatomic changes have cast doubt on the utility of edema-weighted MR imaging as a sole guide to disease activity and treatment in TA. In this study, the greatest utility of MR was in providing a safe, noninvasive means of assessing changes in vascular anatomy. [source]


Modeling Data with Excess Zeros and Measurement Error: Application to Evaluating Relationships between Episodically Consumed Foods and Health Outcomes

BIOMETRICS, Issue 4 2009
Victor Kipnis
Summary Dietary assessment of episodically consumed foods gives rise to nonnegative data that have excess zeros and measurement error. Tooze et al. (2006,,Journal of the American Dietetic Association,106, 1575,1587) describe a general statistical approach (National Cancer Institute method) for modeling such food intakes reported on two or more 24-hour recalls (24HRs) and demonstrate its use to estimate the distribution of the food's usual intake in the general population. In this article, we propose an extension of this method to predict individual usual intake of such foods and to evaluate the relationships of usual intakes with health outcomes. Following the regression calibration approach for measurement error correction, individual usual intake is generally predicted as the conditional mean intake given 24HR-reported intake and other covariates in the health model. One feature of the proposed method is that additional covariates potentially related to usual intake may be used to increase the precision of estimates of usual intake and of diet-health outcome associations. Applying the method to data from the Eating at America's Table Study, we quantify the increased precision obtained from including reported frequency of intake on a food frequency questionnaire (FFQ) as a covariate in the calibration model. We then demonstrate the method in evaluating the linear relationship between log blood mercury levels and fish intake in women by using data from the National Health and Nutrition Examination Survey, and show increased precision when including the FFQ information. Finally, we present simulation results evaluating the performance of the proposed method in this context. [source]
