Hypertension artérielle réfractaire au traitement due au syndrome d'apnées du sommeil et à la prise de médicaments [Obstructive sleep apnea and drugs as causes of treatment-resistant hypertension].

Treatment-resistant hypertension is still common despite the availability of several types of antihypertensive agents acting by different mechanisms. The existence of refractory hypertension should lead to rule out "white-coat hypertension", poor adherence to prescribed drugs as well as classical causes of secondary hypertension such as renal artery stenosis, primary aldosteronism, pheochromocytoma and renal disease. It is also important to consider the possible existence of obstructive sleep apnea or the regular intake of vasopressive drugs or substances.

Fish pedicures: Information for the Public

Although the risk of catching an infection as a result of a fish spa pedicure is likely to be very low, it cannot be completely excluded. However, there are certain things you can do to further reduce your risk of catching or spreading an infection when having one of these treatments.Choosing a salonUse your personal judgment: as with all beauty salons, if it looks unsanitary, do not go there for your treatment. If you are very concerned about the cleanliness of a salon you visit, you can report this to your local Environmental Health department, who will be able to perform an inspection of the premises.When having a treatment, a trained member of staff should perform an inspection of your feet both beforehand, to check for any broken skin / infections, and afterwards, to check for signs of bleeding. They should also ask you to wash your feet with soap and water before putting them in the tank, to make sure that any products you have used that could be harmful to the fish are washed away, and to reduce the risk of spreading any infection.Ask your therapist what other procedures the salon has in place to minimise the risk of infection. The Health Protection Agency, England has produced a set of guidelines for salons which, if followed, will ensure any potential risk of infection is kept to an absolute minimum.Before having the treatment The HPA has identified a number of health conditions or prior treatments which may mean that you should not have a fish pedicure. These are:Leg waxing or shaving in last 24 hoursAny open cuts/wounds/abrasions/broken skin on the feet or lower legsInfection on the feet (including athlete's foot, verruca)Psoriasis, eczema or dermatitis affecting the feet or lower legsDiabetes (increased risk of infection)Infection with a blood borne virus such as Hepatitis B or Hepatitis C or HIVAny immune deficiency due to illness or medicationBleeding disorders or on anticoagulant medication (e.g. heparin or warfarinMore information and advice on fish spa pedicures and the full set of guidance can be found on the Health Protection website www.hpa.org.uk

Perinatal arrhythmias.

Cardiac arrhythmias are very frequent in fetuses and newborns. The prognosis depends on the nature of the arrhythmias but is most often either spontaneously benign or following short-term medication administration. A correct diagnosis is essential for both management and prognosis. It is based on echocardiography during the fetal period and mainly on history, physical exam, and electrocardiogram after birth, but other modalities are available to record transient arrhythmic events. Irregular rhythms are mostly benign and rarely require therapy. In most fetuses and infants, tachyarrhythmias resolve spontaneously or require short-term administration of antiarrhythmics. Approximately one third of these may recur later on, especially during adolescence. Persistent bradyarrhythmias might require pacemaker implantation when associated with failure to thrive or with risk of sudden death. CONCLUSION: Arrhythmias in fetuses and infants are very common and mostly benign. History, physical exam, and recording of the arrhythmia are essential to make a correct diagnosis and establish an appropriate management for the rare potentially harmful arrhythmias.

The expression of GABA receptors in the human auditory cortex

Abstract : GABA, the primary inhibitory neurotransmitter, and its receptors play an important role in modulating neuronal activity in the central nervous system and are implicated in many neurological disorders. In this study, GABAA and GABAB receptor subunit expression was visualized by immunohistochemistry in human auditory areas TC (= primary auditory area), TB, and TA. Both hemispheres from nine neurologically normal subjects and from four patients with subacute or chronic stroke were included. In normal brains, GABAA receptor subunit (α1, α2, & β2/3) labeling produced neuropil staining throughout all cortical layers as well as labeling fibers and neurons in layer VI for all auditory areas. Densitometry profiles displayed differences in GABAA subunit expression between primary and non-primary areas. In contrast to the neuropil labeling of GABAA subunits, GABAB1 and GABAB2 subunit immunoreactivity was revealed on neuronal somata and proximal dendritic shafts of pyramidal and non-pyramidal neurons in layers II-III, more strongly on supra- than in infragranular layers. No differences were observed between auditory areas. In stroke cases, we observed a downregulation of the GABAA receptor α2 subunit in granular and infragranular layers, while the other GABAA and the two GABAB receptor subunits remained unchanged. Our results demonstrate a strong presence of GABAA and GABAB receptors in the human auditory cortex, suggesting a crucial role of GABA in shaping auditory responses in the primary and non-primary auditory areas. The differential laminar and area expression of GABAA subunits that we have found in the auditory areas and which is partially different from that in other cortical areas speaks in favor of a fine turning of GABA-ergic transmission in these different compartments. In contrast, GABAB expression displayed laminar, but not areal differences; its basic pattern was also very similar to that of other cortical areas, suggesting a more uniform role within the cerebral cortex. In subacute and chronic stroke, the selective GABAA α2 subunit downregulation is likely to influence postlesional plasticity and susceptibility to medication. The absence of changes in the GABAB receptors suggests different regulation than in other pathological conditions, such as epilepsy, schizophrenia or bipolar disorder, in which a downregulation has been reported. Résumé : GABA, le principal neurotransmetteur inhibiteur, et ses récepteurs jouent un rôle important en tant que modulateur de l'activité neuronale dans le système nerveux central et sont impliqués dans de nombreux désordres neurologiques. Dans cette étude, l'expression des sous-unités des récepteur GABAA et GABAB a été visualisée par immunohistochimie dans les aires auditives du cortex humains: le TC (= aire auditif primaire), le TB, et le TA. Les deux hémisphères de neuf sujets considérés normaux du point de vue neurologique et de quatre patients ayant subis un accident cérébro-vasculaire et se trouvant dans la phase subaiguë ou chronique étaient inclues. Dans les cerveaux normaux, les immunohistochimies contre les sous-unités α1, α2, & β2/3 du récepteur GABAA ont marqué le neuropil dans toutes les couches corticales ainsi que les fibres et les neurones de la couche VI dans toutes les aires auditives. Le profile densitométrique montre des différences dans l'expression des sous-unités du récepteur GABAA entre les aires primaires et non-primaires. Contrairement au marquage de neuropil par les sous-unités du recepteur GABAA, 1'immunoréactivité des sous-unités GABAB1 et GABAB2 a été révélée sur les corps cellulaires neuronaux et les dendrites proximaux des neurones pyramidaux et non-pyramidaux dans les couches II-III et est plus dense dans les couches supragranulaires que dans les couches infragranulaires. Aucune différence n'a été observée entre les aires auditives. Dans des cas lésionnels, nous avons observé une diminution de la sous-unité α2 du récepteur GABAA dans les couches granulaires et infragranulaires, alors que le marquage des autres sous-unités du récepteur GABAA et des deux sous-unités de récepteur GABAB reste inchangé. Nos résultats démontrent une présence forte des récepteurs GABAA et GABAB dans le cortex auditif humain, suggérant un rôle crucial du neurotransmetteur GABA dans la formation de la réponse auditive dans les aires auditives primaires et non-primaires. L'expression différentielle des sous-unités de GABAA entre les couches corticales et entre les aires auditives et qui est partiellement différente de celle observée dans d'autres aires corticales préconise une modulation fine de la transmission GABA-ergic en ces différents compartiments. En revanche, l'expression de GABAB a montré des différences laminaires, mais non régionales ; son motif d'expression de base est également très semblable à celui d'autres aires corticales, suggérant un rôle plus uniforme dans le cortex cérébral. Dans les phases subaiguë et chronique des accidents cérébro-vasculaires, la diminution sélective de la sous-unité α2 du recepteur GABAA est susceptible d'influencer la plasticité et la susceptibilité postlésionnelle au médicament. L'absence de changement pour les récepteurs GABAB suggère que le récepteur est régulé différemment après un accident cerebro-vasculaire par rapport à d'autres conditions pathologiques, telles que l'épilepsie, la schizophrénie ou le désordre bipolaire, dans lesquels une diminution de ces sous-unités a été rapportée.

Impact of a computerized physician order entry system on compliance with prescription accuracy requirements.

OBJECTIVE: To assess the change in non-compliant items in prescription orders following the implementation of a computerized physician order entry (CPOE) system named PreDiMed. SETTING: The department of internal medicine (39 and 38 beds) in two regional hospitals in Canton Vaud, Switzerland. METHOD: The prescription lines in 100 pre- and 100 post-implementation patients' files were classified according to three modes of administration (medicines for oral or other non-parenteral uses; medicines administered parenterally or via nasogastric tube; pro re nata (PRN), as needed) and analyzed for a number of relevant variables constitutive of medical prescriptions. MAIN OUTCOME MEASURE: The monitored variables depended on the pharmaceutical category and included mainly name of medicine, pharmaceutical form, posology and route of administration, diluting solution, flow rate and identification of prescriber. RESULTS: In 2,099 prescription lines, the total number of non-compliant items was 2,265 before CPOE implementation, or 1.079 non-compliant items per line. Two-thirds of these were due to missing information, and the remaining third to incomplete information. In 2,074 prescription lines post-CPOE implementation, the number of non-compliant items had decreased to 221, or 0.107 non-compliant item per line, a dramatic 10-fold decrease (chi(2) = 4615; P < 10(-6)). Limitations of the computerized system were the risk for erroneous items in some non-prefilled fields and ambiguity due to a field with doses shown on commercial products. CONCLUSION: The deployment of PreDiMed in two departments of internal medicine has led to a major improvement in formal aspects of physicians' prescriptions. Some limitations of the first version of PreDiMed were unveiled and are being corrected.

Soilse annual review 2010.

Soilse, the HSE addiction rehabilitation programme in Dublin North Central, experienced another challenging year in 2010. However, despite budget constraints and logistical and building difficulties, we prioritised the needs of recovering drug abusers with considerable success. Throughout the year, we had enquiries, referrals, programme uptake and successful outcomes. In terms of addiction, the problems are as enduring as ever with complex needs and limited progression opportunities. The rehabilitation strategy published in 2007 has had no practical effect. Yet Soilse saw a clear and positive impact from our work in terms of: stabilising service users; achieving detox; encouraging participants to move from our prescribed medication to our drugfree service; and consolidating these outcomes. Our evidence base continually validates our approach with people who want to become independent of services being facilitated to do so. Soilse did well in 2010 in terms of educational and vocational outcomes, particularly through FETAC but also through comprehensive care planning. We faced protracted difficulties as a result of the staff moratorium and budget cuts, but continued to deliver a professional service, keeping morale and performance high. Our service is based on the following practice standards: holistic assessment care planning care management interagency work quality assurance, and customer service involvementThis resource was contributed by The National Documentation Centre on Drug Use.

Health-related quality of life and functioning in bipolar disorder: the impact of pharmacotherapy.

Bipolar disorder has a major deleterious impact on many aspects of a patient's functioning and health-related quality of life. Although the formal measurement of these deficits has been neglected until recently, many well-designed trials now include an assessment of functioning and health-related quality of life using one or more rating scales. This review describes recent developments in the measurement of functioning and health-related quality of life in bipolar disorder, and discusses the evidence that medications that improve symptoms in bipolar disorder also offer clinically relevant benefits in functioning and health-related quality of life. Direct comparisons of the benefits of medications including atypical antipsychotics are problematic due to differences in trial populations, study durations and rating scales. Data from quetiapine trials indicate that this medication offers prompt and sustained improvement of functioning in patients with mania and enhancement of health-related quality of life in patients with bipolar depression, to accompany the significant improvements in mood episodes.

Cannabis use in a Swiss male prison: qualitative study exploring detainees' and staffs' perspectives.

BACKGROUND: Several studies suggest a high prevalence of cannabis use before and during imprisonment, but subjective perspectives of detainees and staff towards its use in prison are lacking. This issue was explored in the framework of an observational study addressing tobacco use in three Swiss prisons in 2009 and 2010 that involved multiple strands (quantitative and qualitative components). This article presents qualitative data on cannabis use collected in one of the settings. METHODS: We used in-depth semi-structured interviews with both detainees and staff to explore their attitudes towards cannabis in one post-trial male Swiss prison. We performed specific coding and thematic analysis for cannabis with the support of ATLAS.ti, compared detainees' and staff's opinions, and considered the results with regard to drug policy in prison in general. RESULTS: 58 participants (31 male offenders, mean age 35 years, and 27 prison staff, mean age 46 years, 33% female) were interviewed. Detainees estimated the current use of cannabis use to be as high as 80%, and staff 50%. Participants showed similar opinions on effects of cannabis use that were described both at individual and institutional levels: analgesic, calming, self-help to go through the prison experience, relieve stress, facilitate sleep, prevent violence, and social pacifier. They also mentioned negative consequences of cannabis use (sleepiness, decreased perception of danger and social isolation), and dissatisfaction regarding the ongoing ambiguous situation where cannabis is forbidden but detection in the urine was not sanctioned. However, the introduction of a more restrictive regulation induced fear of violence, increased trafficking and a shift to other drug use. CONCLUSION: Although illegal, cannabis use is clearly involved in daily life in prison. A clearer and comprehensive policy addressing cannabis is needed, including appropriate measures tailored to individual users. To sustain a calm and safe environment in prison, means other than substance or medication use are required.

Impact of previous virological treatment failures and adherence on the outcome of antiretroviral therapy in 2007.

BACKGROUND: Combination antiretroviral treatment (cART) has been very successful, especially among selected patients in clinical trials. The aim of this study was to describe outcomes of cART on the population level in a large national cohort. METHODS: Characteristics of participants of the Swiss HIV Cohort Study on stable cART at two semiannual visits in 2007 were analyzed with respect to era of treatment initiation, number of previous virologically failed regimens and self reported adherence. Starting ART in the mono/dual era before HIV-1 RNA assays became available was counted as one failed regimen. Logistic regression was used to identify risk factors for virological failure between the two consecutive visits. RESULTS: Of 4541 patients 31.2% and 68.8% had initiated therapy in the mono/dual and cART era, respectively, and been on treatment for a median of 11.7 vs. 5.7 years. At visit 1 in 2007, the mean number of previous failed regimens was 3.2 vs. 0.5 and the viral load was undetectable (<50 copies/ml) in 84.6% vs. 89.1% of the participants, respectively. Adjusted odds ratios of a detectable viral load at visit 2 for participants from the mono/dual era with a history of 2 and 3, 4, >4 previous failures compared to 1 were 0.9 (95% CI 0.4-1.7), 0.8 (0.4-1.6), 1.6 (0.8-3.2), 3.3 (1.7-6.6) respectively, and 2.3 (1.1-4.8) for >2 missed cART doses during the last month, compared to perfect adherence. From the cART era, odds ratios with a history of 1, 2 and >2 previous failures compared to none were 1.8 (95% CI 1.3-2.5), 2.8 (1.7-4.5) and 7.8 (4.5-13.5), respectively, and 2.8 (1.6-4.8) for >2 missed cART doses during the last month, compared to perfect adherence. CONCLUSIONS: A higher number of previous virologically failed regimens, and imperfect adherence to therapy were independent predictors of imminent virological failure.

Konsensusempfehlungen zur Beurteilung der medizinischen Mindestanforderungen für Fahreignung bei kognitiver Beeinträchtigung [Consensus recommendations for the assessment of fitness to drive in cognitively impaired patients].

Memory Clinics provide evidence based diagnosis and treatment of dementia. Whenever a diagnosis of dementia is made, it is important to inform the patients about the possible impact of dementia on driving. Patients and their next of kin require competent advice whenever this difficult question is addressed and the mobility desire and the risks related to driving need to be carefully weight up. The time of diagnosis does not necessarily equate to the time when a person with dementia becomes an unsafe driver. The cause and severity of dementia, comorbidities and the current medication need to be carefully taken into account for this decision. On behalf of the association of the Swiss Memory Clinics, a group of experts has developed recommendations to assess fitness to drive in cognitively impaired older adults.

Electronic monitoring of compliance to lipid-lowering therapy in clinical practice

Nonadherence to treatment is a common problem in the clinical management of hypercholesterolemic patients. This study was carried out with the aim of monitoring the daily compliance to a 6-month course of lipid-lowering therapy, using a microelectronic device, the Medication Event Monitoring System (MEMS), versus pill count. Forty men with primary hypercholesterolemia were prescribed fluvastatin 1 x 40 mg daily, provided in a MEMS package to record the date and time of each opening of the pillbox. Thirty-nine of 40 patients (98%) completed the study. Total cholesterol and LDL cholesterol levels decreased significantly (18% and 25%, p < 0.001) during the 6-month therapy period. A high mean rate of compliance was achieved by MEMS using the following three indexes--compliance to total prescribed dose (88.8% +/- 13.5%), compliance to prescribed days (82.4% +/- 19.5%), and compliance to prescribed time of day (81.86% +/- 19.5%)--and by pill count (93.4% +/- 9.5%). In addition, the MEMS provided some patterns of nonadherence to medication, undetectable by pill count alone, such as a drug holiday in 38% of cases, a drug omission for more than 7 consecutive days in 9% of cases, and, conversely, use of more than the one prescribed daily dose in 47% of cases. A significant correlation between the rate of compliance and the decrease in LDL cholesterol was observed only when the compliance was assessed by MEMS. The results indicate that MEMS is a useful tool for monitoring compliance in clinical practice and may possibly increase adherence to long-term lipid-lowering therapy.

The leishmaniases - survival and expansion in a changing world: a mini-review

The number of cases of visceral and cutaneous leishmaniasis is increasing globally at an alarming rate irrespective of the region and the leishmaniases are amongst the top emergent diseases in spite of control measures. In the present review attention is drawn to some of the reasons for this. The leishmaniases have expanded beyond their natural ecotopes due to the ecological chaos caused by man and this in turn affects the levels of his exposure to the vectors. Examples of how different phenomana (such as war, civilian migration, immuno-suppression caused by medication and viral infections, globalization of work and leisure and transmission outside endemic areas) contribute to the spread and increase of the disease are discussed.
