Une des questions les plus débattues dans le domaine de l’éthique en ce XXIème siècle entre l’Afrique et le monde occidental concerne le respect de l’intégrité physique des femmes. Parmi les actions humaines qui touchent le plus l’intégrité corporelle, les excisions et les infibulations sont les plus dénoncées en Afrique. Longtemps considérées comme des rites d’initiation pubertaire des filles, ces pratiques sont maintenant considérées comme néfastes à la santé, et communément désignées par la communauté internationale de « mutilations sexuelles féminines ». Au cours des dernières décennies, ces pratiques ont été progressivement interdites légalement tant dans la plupart des pays d’Afrique que dans les pays occidentaux. Le Comité Inter-Africain (CIAF) contre les mutilations sexuelles demande la « tolérance zéro » par rapport à ces pratiques. La communauté internationale les combat avec des armes juridiques, en se référant aux conséquences médicales et aux droits de l’homme. Notre thèse est née d’une interrogation sur les raisons pour lesquelles ces rites se poursuivent encore en Afrique et plus spécialement au Mali, alors que dans les pays occidentaux, on élève fortement la voix pour les dénoncer comme sévices infligés aux femmes. Sur le plan international, on hésite à imposer des valeurs universelles à un phénomène perçu dans une large mesure comme une tradition conforme aux normes sociales des communautés qui les maintiennent. Afin de mieux cerner le sujet, notre questionnement a été le suivant : « Comment les pratiques culturelles des excisions et des infibulations, dans la ville de Bamako au Mali, interpellent-elles l’éthique : en quoi l’analyse de ces rites constitue-t-elle un domaine légitime d’application des principes de la bioéthique ? » Notre réflexion part du postulat que la dignité humaine est une norme à l’aune de laquelle se mesurent les défis éthiques liés à ces rites. Un proverbe Bambara dit ceci : « Une seule main ne lave pas proprement un éléphant ». La logique de cette sagesse met en évidence qu’une seule approche disciplinaire ne saurait faire ressortir les enjeux éthiques de ces pratiques. Notre analyse bioéthique se veut une démarche interdisciplinaire, qui permet d’articuler les approches philosophiques, anthropologiques, sociologiques et biomédicales de ces pratiques. Le premier chapitre, à travers la revue des écrits, présente la problématique de ces rites. Le deuxième chapitre présente le cadre théorique basé sur la notion de dignité humaine et délimite « ses contours, ses sources, ses formes et ses conséquences » afin de la rendre plus efficace et opérationnelle comme moyen de protection de l’être humain. Le troisième chapitre présente la méthodologie de la recherche basée sur la méthode qualitative et l’induction analytique et décrit le contexte de l’étude. Le quatrième chapitre présente les résultats de la recherche qui font ressortir que ces pratiques se résument essentiellement au contrôle du désir sexuel féminin. Ces pratiques sont par ailleurs déritualisées, touchent de plus en plus des enfants, comportent des risques et des conséquences sur la santé avec des coûts humains et financiers pour la société. Le cinquième chapitre analyse ces pratiques avec les principes éthiques qui démontrent qu’elles constituent un problème de santé publique malgré leur caractère culturel. Enfin, le sixième chapitre présente la portée et la limite de la thèse. Celle-ci montre qu’il est possible de mener un débat sur les excisions et les infibulations à travers une éthique de discussion. Elle offre un moyen pour y parvenir avec une vision de la notion de dignité humaine comme une « valeur éthique universelle » susceptible d’être utilisée dans toutes les actions impliquant l’être humain et dans tous les contextes socio-culturels. Notre démarche élargit ainsi le champ d’application des principes bioéthiques à des pratiques non-médicales. Par cette thèse, nous souhaitons contribuer à enrichir la réflexion éthique sur les excisions et les infibulations et inspirer les politiques de santé publique dans le respect des diversités culturelles. Nous espérons pouvoir inspirer aussi d’autres recherches en vue de rapprocher la bioéthique des pratiques culturelles traditionnelles afin de trouver des compromis raisonnables qui pourraient renforcer le rôle de protection de la dignité humaine.

Aim: To describe the patterns of dental attendance and attitudes towards tooth loss of general dental practice patients in Galway. Objectives: 1. To determine the pattern of adult dental attendance in general practices in Galway; and, 2. To examine the oral health attitudes of these patients. Method: Questionnaires were distributed to 311 consecutive adult patients in the waiting rooms of ten general dental practices in Galway, which were randomly selected from the telephone directory. Results: A total of 254 of the 311 questionnaires distributed were fully completed, returned and included in the results, giving a response rate of 81.7%. A total of 59% of dentate participants attended their dentist for annual or biannual examinations compared to 23% of edentate patients. Some 10.5% of medical card holders and 0.5% of non-medical card holders were edentulous. Conclusions: The data from the survey indicated that medical card holders in Galway were more likely to be edentulous than nonmedical card holders. Edentate patients were less likely to be regular dental attenders than dentate patients.

Naloxone – an opioid antagonist that reverses the effects of opioids, including potential death from overdose – is increasingly being distributed in non-medical settings. We conducted a mixed methods study administering a survey to 100 treatment seekers and pursuing observant participation at four methadone/buprenorphine Medication Assisted Therapy (MAT) clinics in North Carolina, USA. Female participants were more likely to have gotten a kit and to carry it with them, whereas male participants were more likely to have witnessed an overdose and to have made use of naloxone. Men discussed the difficulties of carrying the naloxone kits, which are currently too large to fit in a pocket. Public health officials may be relieved to know that naloxone users intend to call emergency services.

Healthcare Associated Infections (HAIs) in the United States, are estimated to cost nearly $10 billion annually. And, while device-related infections have decreased, the 60% attributed to pneumonia, gastrointestinal pathogens and surgical site infections (SSIs) remain prevalent. Furthermore, these are often complicated by antibacterial resistance that ultimately cause 2 million illnesses and 23,000 deaths in the US annually. Antibacterial resistance is an issue increasing in severity as existing antibiotics are losing effectiveness, and fewer new antibiotics are being developed. As a result, new methods of combating bacterial virulence are required. Modulating communications of bacteria can alter phenotype, such as biofilm formation and toxin production. Disrupting these communications provides a means of controlling virulence without directly interacting with the bacteria of interest, a strategy contrary to traditional antibiotics. Inter- and intra-species bacterial communication is commonly called quorum sensing because the communication molecules have been linked to phenotypic changes based on bacterial population dynamics. By disrupting the communication, a method called ‘quorum quenching’, bacterial phenotype can be altered. Virulence of bacteria is both population and species dependent; each species will secrete different toxic molecules, and total population will affect bacterial phenotype9. Here, the kinase LsrK and lactonase SsoPox were combined to simultaneously disrupt two different communication pathways with direct ties to virulence leading to SSIs, gastrointestinal infection and pneumonia. To deliver these enzymes for site-specific virulence prevention, two naturally occurring polymers were used, chitosan and alginate. Chitosan, from crustacean shells, and alginate, from seaweed, are frequently studied due to their biocompatibility, availability, self-assembly and biodegrading properties and have already been verified in vivo for wound-dressing. In this work, a novel functionalized capsule of quorum quenching enzymes and biocompatible polymers was constructed and demonstrated to have dual-quenching capability. This combination of immobilized enzymes has the potential for preventing biofilm formation and reducing bacterial toxicity in a wide variety of medical and non-medical applications.

About 5% of all National Health Service prescriptions in Britain and a quarter of reports of suspected adverse reactions are accounted for by non-steroidal anti-inflammatory drugs. Their prescription was investigated in two computerised group practices serving 11850 patients. Altogether 198 patients receiving repeat prescriptions of non-steroidal anti-inflammatory drugs were identified and relevant clinical details extracted from their notes. Of these patients, 119 were over 65 years old; 172 were receiving one of six different non-steroidal anti-inflammatory drugs; and 76 were taking drugs that can interact with non-steroidal anti-inflammatory drugs. Ninety one patients had one or more medical conditions that may be aggravated by non-steroidal anti-inflammatory drugs, and 36 had experienced side effects important enough for their treatment to be changed. A questionnaire to assess opinions and knowledge of non-steroidal anti-inflammatory drugs was given to 42 general practitioners and 26 rheumatologists. Although the two groups showed a comparable knowledge of the properties and costs of non-steroidal anti-inflammatory drugs, they differed significantly in their views on the circumstances under which these drugs should be used. Clear guidelines on the prescription of these drugs would indicate when careful monitoring is essential for patients to benefit from them safely.

Background: In response to health workforce shortages policymakers have considered expanding the roles that a health professional may perform. A more traditional combination of health professional roles is that of a dispensing doctor (DD) who routinely prescribes and dispenses pharmaceuticals. A systematic review conducted on mainly overseas DDs’ practices found that DDs tended to prescribe more items per patients, less often generically, and showed poorer adherence to best practice. Convenience for patients was cited by both patients and DDs as the main reason for dispensing. In Australia, rural doctors are allowed to dispense Pharmaceutical Benefit Scheme (PBS) subsidised pharmaceutical benefits if there is no reasonable pharmacy coverage. Little was known about the practices of these Australian DDs. Objectives: To examine the PBS prescribing patterns of dispensing with matched non-dispensing doctors and identify factors that influence prescribing behaviour. Method: A sequential explanatory (QUAN-->qual) mixed methodology was utilised. Firstly, rurality-matched DDs’ and non-DDs’ PBS data for fiscal years 2005-7 were analysed against criteria distilled from a systematic review and stakeholder consultations. Secondly, structured interviews were conducted with a purposive sample of DDs to examine the quantitative findings. Key findings: DDs prescribed significantly fewer PBS prescriptions per patients but used Regulation 24 significantly more than non-DDs. Regulation 24 biased the prescribing data. DDs prescribed proportionally more penicillin type antibiotics, adrenergic inhalants and non-steroidal anti-inflammatories as compared to non-DDs. Reasons offered by DD-respondents highlighted that prescribing was influenced by an awareness of cost to the patients, peer pressure and confidential prescriber feedback provided on a regular basis. Implications: This innovative census study does not support international data that DDs are less judicious in their prescribing. There is some evidence that DDs might reduce health inequity between rural and urban Australian, and that the DD health model is valuable to patients in isolated communities.

Objectives: Some doctors perform the dual roles of prescribing and dispensing pharmaceuticals. The dispensing doctors (DDs) role may give rise to prescribing behaviours that vary from those of non-DDs. The aim of this review was to systematically and comparatively appraise the research evidence related to the practices of DDs. Methods: A systematic search of bibliographic databases and reference lists from selected papers were the sources of the data. Inclusion criteria were papers published in English, between 1970 and 2008 that provided quantitative data comparing the practices of DDs and non-DDs. At least two of the authors abstracted data from all eligible papers using a purpose-made data extraction form. Results: Twenty-one papers were included in this review. Evidence indicated that DDs prescribed more pharmaceutical items and less often generically than non-DDs. There was limited evidence to suggest that DDs prescribed less judiciously and were associated with poor dispensing standards. Patient convenience and access to pharmaceuticals were main reasons for doctors to dispense. Conclusion: DDs can fill an important gap in the provision of pharmaceuticals for their patients especially where health workforce shortages exist. There was evidence the dispensing role influenced prescribing. Patient convenience should be balanced against scarce medical resources, being utilised for dispensing.

Objective: To evaluate the prescribing practices of Australian dispensing doctors (DDs) and to explore their interpretations of the findings. Design, participants and setting: Sequential explanatory mixed methods. The quantitative phase comprised analysis of Pharmaceutical Benefits Scheme (PBS) claims data of DDs and non-DDs, 1 July 2005 30 June 2007. The qualitative phase involved semi-structured interviews with DDs in rural and remote general practice across Australian states, August 2009 February 2010. Main outcome measures: The number of PBS prescriptions per 1000 patients and use of Regulation 24 of the National Health (Pharmaceutical Benefits) Regulations 1960 (r. 24); DDs' interpretation of the findings. Results: 72 DDs' and 1080 non-DDs' PBS claims data were analysed quantitatively. DDs issued fewer prescriptions per 1000 patients (9452 v 15057; P = 0.003), even with a similar proportion of concessional patients and patients aged >65 years in their populations. DDs issued significantly more r. 24 prescriptions per 1000 prescriptions than non-DDs (314 v 67; P=0.008). Interviews with 22 DDs explained that the fewer prescriptions were due to perceived expectation from their peers regarding prescribing norms and the need to generate less administrative paperwork in small practices. Conclusions: Contrary to overseas findings, we found no evidence that Australian DDs overprescribed because of their additional dispensing role. MJA 2011; 195: 172-175

Through an examination of Wallace v Kam, this article considers and evaluates the law of causation in the specific context of a medical practitioner’s duty to provide information to patients concerning material risks of treatment. To supply a contextual background for the analysis which follows, Part II summarises the basic principles of causation law, while Part III provides an overview of the case and the reasoning adopted in the decisions at first instance and on appeal. With particular emphasis upon the reasoning in the courts of appeal, Part IV then examines the implications of the case in the context of other jurisprudence in this field and, in so doing, provides a framework for a structured consideration of causation issues in future non-disclosure cases under the Australian civil liability legislation. As will become clear, Wallace was fundamentally decided on the basis of policy reasoning centred upon the purpose behind the legal duty violated. Although the plurality in Rogers v Whitaker rejected the utility of expressions such as ‘the patient’s right of self-determination’ in this context, some Australian jurisprudence may be thought to frame the practitioner’s duty to warn in terms of promoting a patient’s autonomy, or right to decide whether to submit to treatment proposed. Accordingly, the impact of Wallace upon the protection of this right, and the interrelation between it and the duty to warn’s purpose, is investigated. The analysis in Part IV also evaluates the courts’ reasoning in Wallace by questioning the extent to which Wallace’s approach to liability and causal connection in non-disclosure of risk cases: depends upon the nature and classification of the risk(s) in question; and can be reconciled with the way in which patients make decisions. Finally, Part V adopts a comparative approach by considering whether the same decision might be reached if Wallace was determined according to English law.

A 59-year-old man was mistakenly prescribed Slow-Na instead of Slow-K due to incorrect selection from a drop-down list in the prescribing software. This error was identified by a pharmacist during a home medicine review (HMR) before the patient began taking the supplement. The reported error emphasizes the need for vigilance due to the emergence of novel look-alike, sound-alike (LASA) drug pairings. This case highlights the important role of pharmacists in medication safety.

Prescribing for older patients is challenging. The prevalence of diseases increases with advancing age and causes extensive drug use. Impairments in cognitive, sensory, social and physical functioning, multimorbidity and comorbidities, as well as age-related changes in pharmacokinetics and pharmacodynamics all add to the complexity of prescribing. This study is a cross-sectional assessment of all long-term residents aged ≥ 65 years in all nursing homes in Helsinki, Finland. The residents’ health status was assessed and data on their demographic factors, health and medications were collected from their medical records in February 2003. This study assesses some essential issues in prescribing for older people: psychotropic drugs (Paper I), laxatives (Paper II), vitamin D and calcium supplements (Paper III), potentially inappropriate drugs for older adults (PIDs) and drug-drug interactions (DDIs)(Paper IV), as well as prescribing in public and private nursing homes. A resident was classified as a medication user if his or her medication record indicated a regular sequence for its dosage. Others were classified as non-users. Mini Nutritional Assessment (MNA) was used to assess residents’ nutritional status, Beers 2003 criteria to assess the use of PIDs, and the Swedish, Finnish, INteraction X-referencing database (SFINX) to evaluate their exposure to DDIs. Of all nursing home residents in Helsinki, 82% (n=1987) participated in studies I, II, and IV and 87% (n=2114) participated in the study III. The residents’ mean age was 84 years, 81% were female, and 70% were diagnosed with dementia. The mean number of drugs was 7.9 per resident; 40% of the residents used ≥ 9 drugs per day, and were thus exposed to polypharmacy. Eighty percent of the residents received psychotropics; 43% received antipsychotics, and 45% used antidepressants. Anxiolytics were prescribed to 26%, and hypnotics to 28% of the residents. Of those residents diagnosed with dementia, 11% received antidementia drugs. Fifty five percent of the residents used laxatives regularly. In multivariate analysis, those factors associated with regular laxative use were advanced age, immobility, poor nutritional status, chewing problems, Parkinson’s disease, and a high number of drugs. Eating snacks between meals was associated with lower risk for laxative use. Of all participants, 33% received vitamin D supplementation, 28% received calcium supplementation, and 20% received both vitamin D and calcium. The dosage of vitamin D was rather low: 21% received vitamin D 400 IU (10 µg) or more, and only 4% received 800 IU (20 µg) or more. In multivariate analysis, residents who received vitamin D supplementation enjoyed better nutritional status, ate snacks between meals, suffered no constipation, and received regular weight monitoring. Those residents receiving PIDs (34% of all residents) more often used psychotropic medication and were more often exposed to polypharmacy than residents receiving no PIDs. Residents receiving PIDs were less often diagnosed with dementia than were residents receiving no PIDs. The three most prevalent PIDs were short-acting benzodiazepine in greater dosages than recommended, hydroxyzine, and nitrofurantoin. These three drugs accounted for nearly 77% of all PID use. Of all residents, less than 5% were susceptible to a clinically significant DDI. The most common DDIs were related to the use of potassium-sparing diuretics, carbamazepine, and codeine. Residents exposed to potential DDIs were younger, had more often suffered a previous stroke, more often used psychotropics, and were more often exposed to PIDs and polypharmacy than were residents not exposed to DDIs. Residents in private nursing homes were less often exposed to polypharmacy than were residents in public nursing homes. Long-term residents in nursing homes in Helsinki use, on average, nearly eight drugs daily. The use of psychotropic drugs in our study was notably more common than in international studies. The prevalence of laxatives equaled other prior international studies. Regardless of the known benefit and recommendation of vitamin D supplementation for elderly residing mostly indoors, the proportion of nursing home residents receiving vitamin D and calcium was surprisingly low. The use of PIDs was common among nursing home residents. PIDs increased the likelihood of DDIs. However, DDIs did not seem a major concern among the nursing home population. Monitoring PIDs and potential drug interactions could improve the quality of prescribing.

Objective: In Australian residential aged care facilities (RACFs), the use of certain classes of high-risk medication such as antipsychotics, potent analgesics, and sedatives is high. Here, we examined the prescribed medications and subsequent changes recommended by geriatricians during comprehensive geriatric consultations provided to residents of RACFs via videoconference. Design: This is a prospective observational study. Setting: Four RACFs in Queensland, Australia, are included. Participants: A total of 153 residents referred by general practitioners for comprehensive assessment by geriatricians delivered by video-consultation. Results: Residents’ mean (standard deviation, SD) age was 83.0 (8.1) years and 64.1% were female. They had multiple comorbidities (mean 6), high levels of dependency, and were prescribed a mean (SD) of 9.6 (4.2) regular medications. Ninety-one percent of patients were taking five or more medications daily. Of total medications prescribed (n=1,469), geriatricians recommended withdrawal of 9.8% (n=145) and dose alteration of 3.5% (n=51). New medications were initiated in 47.7% (n=73) patients. Of the 10.3% (n=151) medications considered as high risk, 17.2% were stopped and dose altered in 2.6%. Conclusion: There was a moderate prevalence of potentially inappropriate high-risk medications. However, geriatricians made relatively few changes, suggesting either that, on balance, prescription of these medications was appropriate or, because of other factors, there was a reluctance to adjust medications. A structured medication review using an algorithm for withdrawing medications of high disutility might help optimize medications in frail patients. Further research, including a broader survey, is required to understand these dynamics.

Comorbidity of depression risks is common among cancer patients. The pharmacological treatment of depression is antidepressants. However, antidepressants may interact with anticancer drugs or cause adverse reactions. The prescription practice of antidepressants to cancer patients in Australia is not well documented. Our systematic review and meta-analysis identified that the overall prevalence rate of antidepressants was 15.6% varied widely by world-region and gender. A retrospective case-control study was undertaken to determine the recent prescription practice of antidepressants to cancer and non-cancer patients in Australia. Mirtazapine was the highly prescribed antidepressants to cases, whereas Desvenlafaxine was prescribed to controls. Considerable variation in the prescribing patterns of antidepressants was identified. Prospective studies are needed to ascertain whether patients are being treated optimally.
