False gingival enlargement as a diagnostic problem: a case report

INTERNATIONAL JOURNAL OF DENTAL HYGIENE, Issue 1 2008
L Kesi
Abstract:, The aim of the case report was to describe gingival enlargement in a patient who came to the Department of Oral Medicine and Periodontology at Ni, Dental Clinic. After anamnesis had been taken, and following clinical examination, laboratory blood analysis, radiological examination and pathological examination, it was established that gingival enlargement was a consequence of medicament injection. We are of the opinion that gingival enlargement was a consequence of sclerotic agent injection. [source]

Quality of life in patients with burning mouth syndrome

JOURNAL OF ORAL PATHOLOGY & MEDICINE, Issue 7 2008
Pía López-Jornet
Objective:, To study the quality of life in patients with burning mouth syndrome (BMS), our primary aim was to compare BMS patients with healthy controls and the secondary aim was to compare subgroups of BMS patients on the type of therapy received; using the Medical Outcome Short Form Health Survey Questionnaire (SF-36) and the Oral Health Impact Profile (OHIP-49) as measurement instruments. Method:, Sixty consecutive patients (10 males and 50 females) with BMS were studied in the Department of Oral Medicine (Faculty of Medicine and Dentistry, University of Murcia, Spain), while 60 healthy patients were used as controls. The Spanish version of the SF-36 was used to evaluate general quality of life, together with the OHIP-49 in its Spanish version. Results:, Regarding general quality of life as assessed with the SF-36, and on comparing the BMS vs. the control groups, lower scores were obtained in the former in all domains (P < 0.001). The OHIP-49 in turn yielded significant differences in each of the domains vs. the controls. No significant differences were found between the patients with BMS in any domain regarding parafunctional habits and the presence of dentures. In relation to the different treatments, significant differences were recorded in functional limitation (P = 0.02) and physical pain (P = 0.033). Conclusion:, Patients with BMS yield poorer scores on all scales vs. the healthy controls when applying the SF-36 and OHIP-49. [source]

Stimulated whole salivary flow rate and composition in menopausal women with oral dryness feeling

ORAL DISEASES, Issue 3 2007
F Agha-Hosseini
The aim of this study was to compare stimulated whole saliva flow rate and composition of menopausal women with/without oral dryness (OD) feeling. A case,control study was carried out in 42 selected menopausal women aged 52,73 years with or without OD feeling (21 as case and 21 as control) conducted at the Clinic of Oral Medicine, Tehran University of Medical Sciences. Paraffin-stimulated saliva samples were obtained by expectoration. The stimulated whole saliva composition was measured by a spectrophotometer [magnesium (Mg+2), calcium (Ca+2), chloride (Cl,), inorganic phosphate (Pi) and total protein], flame-photometry [sodium (Na+)] and ion selective electrode (ISE) [potassium (K+)] methods. No significant differences were found in stimulated whole saliva flow rate, Mg+2, Cl,, Pi, Na+, K+ and total protein concentrations between the two groups, but the mean calcium concentration was significantly higher in cases than in controls (P = 0.003). It seems that the level of salivary calcium concentration may be higher in menopausal women with OD feeling than in the control group. [source]

Burning mouth syndrome: a retrospective study investigating spontaneous remission and response to treatments

ORAL DISEASES, Issue 2 2006
A Sardella
Objective:, The aim of this investigation was to evaluate the spontaneous remission rate of burning mouth syndrome (BMS) in a group of subjects suffering from this syndrome. Subjects and Methods:, The medical records of BMS patients attending the Unit of Oral Medicine (1995,2002) were reviewed. The patients with a follow-up period of at least 18 months were then contacted over phone and interviewed using a structured ad hoc questionnaire to record their current symptoms and data about their treatment responses to the therapies. Results:, Forty-eight women and five men with a mean age of 67.7 years (range 33,82 years) were included in the study (mean duration of BMS 5.5 years, s.d. ±1.9 years, mean follow-up period of 56 months). As a consequence of different treatments, 26 patients (49.0%) reported no change in oral symptoms, 15 (28.3%) moderate improvement and 10 (18.9%) a worsening of oral complaints. Only two patients (3.7%) reported a complete spontaneous remission of oral symptoms without any treatment. Conclusions:, In this study, a complete spontaneous remission was observed in 3% of the patients within 5 years after the onset of BMS. A moderate improvement was obtained in <30% of the subjects.

Tumor-associated glycoprotein 72 (TAG-72) expression in salivary gland neoplasia: an immunohistochemical study using the monoclonal antibody (MAb) CC49

ORAL DISEASES, Issue 2 2000
A. Epivatianos
OBJECTIVES: The purpose of this study was to investigate immunohistochemically the expression of tumor-associated glycoprotein 72 (TAG-72) using the monoclonal antibody (MAb) CC49 in salivary gland neoplasia and normal salivary glands in an attempt to determine the potential usefulness of MAb CC49 in diagnostic and therapetic applications. MATERIALS AND METHODS: Eighty-six specimens (21 benign tumors, 41 malignant, and 24 normal salivary glands), fixed in 10% formalin and embedded in paraffin, were retrieved from the files of the Department of Oral Medicine and Oral Pathology at the Dental School of Aristotle University, Thessaloniki, Greece, and were retrospectively studied with hematoxylin and eosin and with the streptavidin-biotin-complex method using the MAb CC49. RESULTS: Strong immunoreactivity for TAG-72 was observed in salivary duct carcinoma, adenocarcinoma, papillary cystadenocarcinoma, low-grade mucoepidermoid carcinoma, normal submandibular, sublingual, and minor salivary glandS. Weak or no immunoreactivity was found in adenoid cystic carcinoma, basal cell adenocarcinoma, polymorphous low-grade adenocarcinoma, and normal parotid gland. CONCLUSIONS: Our results suggest the potential use of MAb CC49 in the differential diagnosis of some salivary gland neoplasms in which their histopathologic features overlap, and in the radiation immunolocalization and immunotherapy of malignant tumors that are localized in the parotid gland.

Oral medicine in Australia 2000,2010.

AUSTRALIAN DENTAL JOURNAL, Issue 2010
A publications overview
Abstract Specialties within health care are often identified by the public profile provided by members within the private clinical practice arena. This is clearly important but often the real activity of a specialty discipline exists within the training institutions. This is an unseen area for most, both members of the public as well as professional colleagues, as papers reporting developments of all kinds are delivered to highly specific target audiences and publications reporting research are published in journals again targeting specific audiences. Publication in national journals is important and provides a glimpse of research activities and a wealth of clinical material in the form of reviews and case reports directed again to a specific target audience. This paper addresses the profile of oral medicine in Australia by presenting the papers published in the Australian Dental Journal within a 10-year bracket. [source]

Periodontology/Oral Medicine: Periodontal infections and cardiovascular disease,how strong is the association?

ORAL DISEASES, Issue 6 2000
GC Armitage
In the past decade there has been renewed interest in the old hypothesis that infections increase the risk of developing cardiovascular disease and stroke. There is now a convincing body of evidence that atherosclerosis has a major inflammatory component and is much more than the simple vascular accumulation of lipids. Infectious agents that have been linked to an increased risk of coronary heart disease (CHD) include Chlamydia pneumoniae, Helicobacter pylori, cytomegalovirus, and herpesviruses. The concept has emerged that each of these agents is an independent risk factor for CHD and that common chronic infections are important. In addition, periodontal infections have also been implicated as one of several factors contributing to the development of CHD. Evidence supporting a causative role of chronic infections in CHD is largely circumstantial. However, the evidence is sufficiently strong to warrant further examination of the possible link between chronic infections and CHD. In this review the lines of evidence for a causative role of C. pneumoniae in the development of CHD are summarized and contrasted with the lines of evidence suggesting a periodontal infection - CHD association. If common or widespread chronic infections are truly important risk factors for CHD, it is unlikely that a single infection will be shown to be causative. It is likely that the entire microbial burden of the patient from several simultaneous chronic infections is more important (eg, H. pylori -caused gastric ulcers +C. pneumoniae -caused bronchitis + periodontitis). Increased cooperation between cardiologists and periodontists will be required to determine if, and what, combinations of common chronic infections are important in the pathogenesis of CHD and stroke.

Probiotics: do they have a role in oral medicine and dentistry?

EUROPEAN JOURNAL OF ORAL SCIENCES, Issue 3 2005
Jukka H. Meurman
This review describes current knowledge on probiotic bacteriotherapy from the oral health perspective. Recent experimental studies and results from randomized controlled trials have shown that certain gut bacteria, in particular species of Lactobacillus and Bifidobacterium, may exert beneficial effects in the oral cavity by inhibiting cariogenic streptococci and Candida sp. Probiotics have been successfully used to control gastro-intestinal diseases. They also appear to alleviate symptoms of allergy and diseases with immunological pathology. The mechanisms of probiotic action appear to link with colonization resistance and immune modulation. Lactic acid bacteria can produce different antimicrobial components such as organic acids, hydrogen peroxide, carbon peroxide, diacetyl, low molecular weight antimicrobial substances, bacteriocins, and adhesion inhibitors, which also affect oral microflora. However, data is still sparse on the probiotic action in the oral cavity. More information is needed on the colonization of probiotics in the mouth and their possible effect on and within oral biofilms. There is every reason to believe that the putative probiotic mechanisms of action are the same in the mouth as they are in other parts of the gastrointestinal tract. Because of the increasing global problem with antimicrobial drug resistance, the concept of probiotic therapy is interesting and pertinent, and merits further research in the fields of oral medicine and dentistry.

Periodontal status and IOTN interventions among young hemophiliacs

HAEMOPHILIA, Issue 4 2006
S. AZHAR
Summary., ,Fifty-two young individuals suffering from severe haemophilia A and B volunteered to be compared with school- and college-going students for oral health status description and subsequent management. A total of 244 students (84.42% boys and 15.58% girls) with the age group of 13,23 years were divided into two groups, A and B (controls). The purpose of this study was to increase awareness about evidence-based dental practices by oral examinations followed by comparisons of periodontal health and prevalence of malocclusions among medically compromised students and healthy controls. Results described the oral health in severe haemophilic population to be compromised with combined simplified health index score of 0.50 and Decayed/Modified/Filled Teeth (DMFT) index score of 2.07 when compared with 0.42 and 0.95, respectively, among group B. Although prevalence of malocclusion and orthodontic treatment needs among group A were higher, yet it was not confirmed as a reason for degraded dental and periodontal status. However, spontaneous and/or toothbrush (trauma)-induced gingival bleeding episodes among group A could be explained as factors discouraging oral hygiene maintenance, particularly self-administered measures. Four haemophiliacs presented with symptoms of Temporomandibular Joint Dysfunction Syndrome (TMPDS). Evidence-based oral medicine and clinical practices need to be encouraged and applied to enhance the quality of life among haemophiliacs, particularly in developing world. Dental treatment needs of haemophilic population appear to be greater and maybe incorporated in routine dental practices, at institutional and individual levels. [source]

A12. IPL therapy in the inflammatory stage of rosacea

JOURNAL OF COSMETIC DERMATOLOGY, Issue 2 2002
M Rone
The inflammatory stage of Rosacea iscommonly treated with topical or oral antibiotics. However, if additional erythema and telangiectasias are present, antibiotics are not successful. IPL (intense pulsed light) is mostly involved when only initial or residual telangiectasias are present. Application of IPL simultaneously with topical or oral medicine could be an effective form of treatment in the inflammatory stage of rosacea. This study was performed in order to detect the effect of IPL application with simultaneous topical antibiotics in inflammatory rosacea and to assess the efficacy of IPL therapy in routine treatment of rosacea. Twenty patients aged between 34 and 70 with papulopustular rosacea (14 female and 7 male) were included in the study. Ten patients (group I) were treated for 21 weeks with topical metronidazole. The other ten patients (group II) received an additional 3 sessions with IPL 515,755 nm Photoderm VL technology over 4 weeks. Treatment affectivity was recorded by digital visualisation and patient satisfaction scale before each IPL session. In all patients, significant reductions in papulopustular elements were observed. Eight out of 10 patients (group I) still showed permanent erythema and telangiectasias despite topical treatment. In 3/10 patients a few telangiectasias remained following the treatment in contrast to 5/10 satisfied group I patients. The most effective treatment was the application of 570 nm and 590 nm wavelength at a fluence of 25,55 J/cm2. Application of IPL in inflammatory rosacea is equally as safe and effective in residual or initial lesions. Moreover, in combination with antibiotics, it promotes reduction of all symptoms, is less time-consuming and is more successful for patients. The pathogenetic influence of IPL in rosacea seems not only to be limited to selective photothermolysis of dilated blood vessels, but may also have immunomodulatory effects on inflammatory processes and possibly on collagen remodelling. The combination of IPL and antibiotics from theoutset of rosacea therapy is considered to be highly effective. [source]

The use of quality of life measures in oral medicine: a review of the literature

ORAL DISEASES, Issue 5 2010
R Ni Riordain
Oral Diseases (2010) 16, 419,430 Objectives:, To explore the use of patient reported quality of life measures in oral medicine, to highlight the importance of use of these measures in oral medicine practice and to provide guidance for the selection of such measures in the future. Methods:, A detailed literature review was undertaken to investigate the use of quality of life measures in oral medicine. The databases searched were MEDLINE (through PubMed), EMBASE, CINDHL, Web of Science Citation Index and the Cochrane Database of Systematic Reviews and randomised controlled trials. Results:, The initial literature search yielded a total of 5310 citations; however, only 63 of these fulfilled the inclusion criteria. Twenty-two articles were regarding oral mucosal conditions, 14 related to orofacial pain disorders and 27 were regarding salivary gland-related conditions. Conclusions:, The evaluation of quality of life in oral medicine has a broad applicability, providing information in treatment-based studies and population-based studies. A predominance of generic and oral health specific quality of life measures are being used to a limited extent in oral medicine practice. A scarcity of reports of the development, validation or use of disease specific measures is evident. [source]

Design and statistical analysis of oral medicine studies: common pitfalls

ORAL DISEASES, Issue 3 2010
L Baccaglini
Oral Diseases (2010) 16, 233,241 A growing number of articles are emerging in the medical and statistics literature that describe epidemiologic and statistical flaws of research studies. Many examples of these deficiencies are encountered in the oral, craniofacial, and dental literature. However, only a handful of methodologic articles have been published in the oral literature warning investigators of potential errors that may arise early in the study and that can irreparably bias the final results. In this study, we briefly review some of the most common pitfalls that our team of epidemiologists and statisticians has identified during the review of submitted or published manuscripts and research grant applications. We use practical examples from the oral medicine and dental literature to illustrate potential shortcomings in the design and analysis of research studies, and how these deficiencies may affect the results and their interpretation. A good study design is essential, because errors in the analysis can be corrected if the design was sound, but flaws in study design can lead to data that are not salvageable. We recommend consultation with an epidemiologist or a statistician during the planning phase of a research study to optimize study efficiency, minimize potential sources of bias, and document the analytic plan.

Scope of practice, referral patterns and lesion occurrence of an oral medicine service in Australia

ORAL DISEASES, Issue 4 2008
CS Farah
Aim:, The purpose of this study was to examine the scope of practice, lesion occurrence and utilisation of referral-based hospital and private practice oral medicine and oral pathology (OMP) services in Australia. Materials and methods:, Clinical records of patients referred to a hospital (n=500) and private (nbequals;1104) OMP clinic were audited. For each patient, the following parameters were recorded: age, gender, source of referral, reason for referral, site of lesion/condition if applicable, medical and drug history, diagnostic services utilised, clinical and histopathological diagnoses rendered, medications prescribed and further treatment required. Results:, A majority of the referrals were generated by general dental practitioners. The most commonly seen problems were epithelial hyperplasia/hyperkeratosis, oral candidosis, oral lichen planus, xerostomia, recurrent aphthous ulcers and burning mouth syndrome. OMP specialists requested diagnostic imaging for 13% of hospital and 9.42% of private patients, diagnostic biopsies were required for 18.4% of hospital and 19.3% of private patients, blood tests were ordered for 14.4% of hospital and 12.13% of private patients, while medications were prescribed for approximately 36% of hospital and 51% of private patients. Conclusions:, This study is the first to detail the scope of practice, lesion occurrence and utilisation of services offered by OMP specialists in Australia. The demand for OMP services is strong.

Therapeutic doses of glucocorticoids: implications for oral medicine

ORAL DISEASES, Issue 5 2006
SK Baid
Glucocorticoids can cause adverse systemic side-effects ranging from iatrogenic Cushing's syndrome during treatment, to hypothalamic,pituitary,adrenal axis suppression and clinically significant adrenal insufficiency when the agents are discontinued. While the oral route of administration is most often implicated, it is now becoming more apparent that inhaled and topical administration also can cause these effects. Given the high therapeutic value of glucocorticoids, the ability to prescribe these agents while maintaining a low risk-to-benefit ratio for patients is critical. The aim of this review is to provide oral healthcare practitioners with a practical guide to commonly used glucocorticoids, their adverse effects, and perioperative use. [source]

Cryotherapy for treatment of oral lesions

AUSTRALIAN DENTAL JOURNAL, Issue 1 2006
CS Farah Senior Lecturer
Abstract Cryotherapy is the deliberate destruction of tissue by application of extreme cold. It is well received by patients due to a relative lack of discomfort, the absence of bleeding and minimal to no scarring after healing. It has many applications in oral medicine and clinical oral pathology, and is extremely useful in patients for whom surgery is contra-indicated due to either age or medical history. In this paper we outline the principles, mechanisms of action, and current applications of cryotherapy in the treatment of oral lesions, and present some clinical cases. [source]

Orofacial granulomatosis in childhood,a clinical entity that may indicate Crohn's disease as well as food allergy

ACTA PAEDIATRICA, Issue 7 2009
Robert Saalman
Abstract Aim:, Orofacial granulomatosis (OFG) is a rare clinical entity with orofacial swelling in association with oral lesions such as mucosal oedema, ulcerations and mucosal tags. The aim of this prospective study was to evaluate the connection between OFG in childhood and systemic disease. Methods:, During a 3-year period, eight children (9,16 years old) who had been referred to the clinic of oral medicine were diagnosed solely with OFG. Thus, none of them had any known systemic disease or gastrointestinal symptoms at the time of referral. The children were then medically examined and followed up for 6,8 years at the department of paediatrics for systemic disease with specific emphasis on inflammatory disorders elsewhere in the gastrointestinal tract. Results:, During follow-up, four patients were diagnosed with Crohn's disease (CD). Further, one girl was found to have a food allergy-induced OFG, with delayed-type hypersensitivity to oats. One boy developed both diabetes and celiac disease during the follow-up. Only two patients had no diagnosis of systemic disease at the end of the observation period. Conclusion:, OFG in childhood seems to be frequently related to systemic disease, and children with OFG should be referred to a paediatrician for examination and follow-up. [source]

Beliefs of chronically ill Japanese patients that lead to intentional non-adherence to medication

JOURNAL OF CLINICAL PHARMACY & THERAPEUTICS, Issue 5 2004
N. Iihara BS
Summary Objective:, To identify factors, associated with personal beliefs, involved in intentional non-adherence to prescribed medication of Japanese patients with chronic diseases. Methods:, A cross-sectional study of Japanese subjects with chronic, primarily liver, gastrointestinal, or nervous system diseases who had been prescribed oral medicines for regular use, was performed. The subjects were admitted to a university hospital and were interviewed face-to-face on admission. Intentional non-adherence was defined as experience of deliberate adjustment of self-managed prescription medicines during the few months prior to hospital admission. Patients' beliefs about taking medicines were assessed from the perspective of what the patient valued in order to take medicines without anxiety; whether the patient valued information about the medication such as its function and side-effects and/or mutual reliance on doctors. Using logistic multivariate regression analyses, factors associated with intentional non-adherence were identified. Results:, Among 154 subjects, 51 showed intentional non-adherence. Intentional non-adherence was associated with the following three factors: (a) the patients' beliefs with respect to taking medicines without anxiety, especially putting no value on mutual reliance on the patient,doctor relationship (P < 0·001) and putting great value on knowing the drug's side-effects (P < 0·001), (b) poor comprehension of general aspects of medication (P for trend <0·001), and (c) being in the prime of life (40,59 years) (P = 0·011). Comprehension of the function of each medicine, experience of side-effects, anxiety about taking medicines, and the number of types of medicines taken, were not associated with non-adherence. Conclusions:, Beliefs on which individual Japanese patients with chronic diseases attach value in order to take medicines without anxiety were potential factors for intentional non-adherence. This emphasizes the necessity of a patient-oriented approach to take account of patients' personal beliefs about medicines to increase adherence rate in Japan. [source]

Latest news and product developments

PRESCRIBER, Issue 4 2007
Article first published online: 3 APR 200
Low-dose aspirin may reduce asthma risk Low-dose aspirin may reduce the risk of new-onset asthma, according to a US analysis (Am J Respir Crit Care Med 2007;175:120-5). Prompted by speculation of such a link, the authors conducted a post-hoc analysis of the Physicians' Health Study, a placebo-controlled study of aspirin 325mg on alternate days involving 22 071 men aged 40-84. The risk of developing a new diagnosis of asthma during the five-year study was reduced by 22 per cent (p=0.045) among those taking aspirin. However, the number of cases was low: 113 among aspirin recipients and 145 with placebo. The clinical importance of this finding is therefore uncertain, though it received wide coverage in the lay media. Lifestyle changevsdrugs in type 2 diabetes Modifying lifestyle is at least as effective as drugs in delaying the onset of type 2 diabetes in people with impaired glucose tolerance, according to a study from Leicester (BMJ online. doi: 10.1136/bmj.39063.689375.55). The meta-analysis of 17 trials involving 8084 participants found that lifestyle change or orlistat approximately halved the risk of progressing to diabetes, whereas oral hypoglycaemic agents reduced the risk by 30 per cent. A Chinese herb, jiang tang bushen, reduced the risk by two-thirds. The analysis was conducted before the findings of major trials of rosiglitazone (Avandia) , DREAM and ADOPT , were published. Optician prescribing The diagnosis and treatment of disorders such as conjunctivitis by opticians is to be an enhanced service that PCTs can commission according to local need, a Department of Health review has concluded. The General Ophthalmic Services Review considered new arrangements to support PCTs provide ophthalmic services. Professional representatives proposed that the diagnosis and treatment of some eye conditions should be classed as ,additional services' that PCTs should be obliged to commission. While the Department agreed that opticians can play an important role, it found a lack of evidence of benefits and concluded that PCTs should be able to determine their level of services. A commissioning toolkit has been produced to help implement the review's findings. Warfarin stroke risk A four-fold increase in warfarin use has been linked with an increased incidence of intracerebral haemorrhage in a US study (Neurology 2007;68:116-21). Reviewing all first admissions for haemorrhagic stroke in the Cincinnati area, the study found that the proportion of cases associated with warfarin or heparin increased from 5 per cent in 1988 to 9 per cent in 1993/94 and 17 per cent in 1999. The annual incidence among patients aged 80 or older increased from 2.5 to 46 per 100 000 from 1988 to 1999. During the same period, warfarin distribution increased four-fold and there was no change in the incidence of thromboembolic strokes. Co-proxamol will go, MHRA reaffirms The MHRA has confirmed that it still intends to withdraw co-proxamol from the market despite protestations from MPs. The issue was raised by two MPs , one a member of the Health Select Committee , in a House of Commons debate. Both called for the withdrawal process to be abandoned, arguing that GPs should have the right to prescribe a drug for which there may be no alternative. The MHRA has restated its view that the risk from overdose with co-proxamol outweighs its benefits, adding: ,The avoidable death toll from co-proxamol overdose cannot be ignored. Sometimes regulation has to balance the needs of the individual against the benefits at a population level. In this case the removal of marketing authorisations with continued use possible in exceptional circumstances is the best balance that could be achieved. The public health gain is already becoming apparent.' Co-proxamol may still be prescribed as an unlicensed drug after its product licence is withdrawn at the end of this year. Guide to pharmacy services A guide to community pharmacy services has been published for patients, carers and members of patient organisations. Developed by the South East Local Pharmaceutical Committee Forum, Understanding and Making the Best Use of Community Pharmacy explains what pharmacies offer and the services available under the 2005 pharmacy contract. Copies can be downloaded from www.psnc.org.uk/resources. Little benefit from opioids for back pain There is little evidence that opioids relieve chronic back pain but the risk of abuse is high, according to a US analysis (Ann Intern Med 2007;146:116-27). The systematic review of trials of oral, topical and transdermal opioids in the treatment of chronic back pain found no trials lasting more than 16 weeks. There was no significant reduction in pain in placebo-controlled trials and limited, nonsignificant pain reductions in comparative trials. By contrast, estimates of prevalence of current substance misuse were as high as 43 per cent and that of ,aberrant medication-taking behaviours' ranged from 5 to 24 per cent. Dual antiplatelet therapy with drug-eluting stents Patients with drug-eluting stents should not stop dual antiplatelet therapy prematurely (Circulation 2007; published online 15 January; DOI: 10.1161/CIRCUL ATIONAHA.106.180944). Although 12 months' treatment with low-dose aspirin plus a thienopyri- dine, eg clopidogrel (Plavix) and ticlopidine, has been shown to reduce cardiac events after implanting a drug-eluting stent, it is not uncommon for the thienopyridine to be discontinued. Health professionals must do more to educate patients about their treatment and the risks associated with stopping. Scottish approval The SMC (www.scottishmedicines.org.uk) has approved varenicline (Champix) for use within NHS Scotland as part of a smoking cessation programme; it notes that the benefits of extending a course of treatment beyond the initial 12 weeks are modest. Controversially, the SMC has not approved omalizumab (Xolair) as add-on therapy for severe persistent allergic asthma on the grounds that an economic case had not been made. Asthma UK criticised the decision as unjust and inhumane. NICE is due to publish an appraisal of omalizumab later this year. No decline with anti- psychotics Treatment with anti- psychotics does not hasten cognitive decline in patients with Alzheimer's disease, say investigators from London (J Neurol Neurosurg Psychiatry 2007;78:25-9). Their prospective study of 224 patients found no difference in the rate of cognitive decline in those treated with antipsychotics (atypical or otherwise) for at least six months. Label translation online Health IT consultancy Rxinfo has developed a website offering translations of the most common types of labelling.
