Douleurs neuropathiques : quelques pistes pour une évaluation structurée et une prise en charge spécifique et globale [Neuropathic pain: tips and tools for specific and comprehensive pain management]

Les syndromes neuropathiques sont caractérisés par une douleur d'intensité élevée, de longue durée et résistante aux analgésiques classiques. De fait, il existe un risque important de répercussions sur la vie et le bien-être des patients. A travers une vignette clinique, cet article abordera le diagnostic, le traitement spécifique et l'impact de la douleur neuropathique sur la qualité de vie et les conséquences psychologiques associées, comme la dépression et l'anxiété. Nous présenterons des outils validés qui permettent d'objectiver la composante neuropathique aux douleurs et les comorbidités psychiatriques associées. Cette évaluation globale favorise un meilleur dialogue avec les patients ainsi que l'élaboration de stratégies thérapeutiques, notamment par le biais d'antidépresseurs, dont l'efficacité sera discutée en fin d'article. Neuropathic pain syndromes are characterized by intense and long lasting pain that is resistant to usual analgesics. Patients are therefore at high risk of decreased quality of life and impaired well-being. Using a case report, we will consider in this article the diagnosis and treatment of neuropathic pain as well as its impact on the quality of life including psychological consequences such as depression and anxiety. We will present simple and reliable scales that can help the general practitioner evaluate the neuropathic component of the pain syndrome and its related psychiatric co-morbidities. This comprehensive approach to pain management should facilitate communication with the patient and help the practitioner select the most appropriate therapeutic strategy, notably the prescription of antidepressants, the efficacy of which we will discuss at the end of the article.

Anévrismes de l'artère poplitée: quelle prise en charge en 2013 ? [Popliteal artery aneurysms: management in 2013].

Although rare, popliteal artery aneurysms are the most common peripheral aneurysms and are frequently associated with abdominal aorta aneurysms. They are often bilateral. One third of patients are asymptomatic at diagnosis, with an insidious evolution. Symptomatic patients may present with symptoms of either acute ischemia or chronic ischemia, or rarely compression or rupture. Surgical exclusion of aneurysm followed by venous bypass remains the treatment of choice. Endovascular treatment is an attractive alternative currently reserved for patients at high risk, with good anatomical criteria. Elective treatment before symptoms onset is preferable given the best results in terms of patency and complications. A conservative approach is allowed for small aneurysms without major embolic risk provided careful monitoring by ultrasound.

High-density electric source imaging (esi) in focal epilepsy: a prospective study of 150 operated patients

Purpose: EEG is mandatory in the diagnosis of the epilepsy syndrome. However, its potential as imaging tool is still under estimated. In the present study, we aim to determine the prerequisites of maximal benefit of electric source imaging (ESI) to localize the irritative zone in patients with focal epilepsy. Methods: One hundred fifty patients suffering from focal epilepsy and with minimum 1 year postoperative follow-up were studied prospectively and blinded to the underlying diagnosis. We evaluated the influence of two important factors on sensitivity and specificity of ESI: the number of electrodes (low resolution, LR-ESI: <30 versus high resolution, HR-ESI: 128-256 electrodes), and the use of individual MRI (i-MRI) versus template MRI (t-MRI) as the head model. Findings: ESI had a sensitivity of 85% and a specificity of 87% when HR-ESI with i-MRI was used. Using LR-ESI, sensitivity decreased to 68%, or even 57% when only t-MRI was available. The sensitivity of HR-ESI/i-MRI compared favorably with those of MRI (76%), PET (69%) and ictal/interictal SPECT (64%). Interpretation: This study on a large patient group shows excellent sensitivity and specificity of ESI if 128 EEG channels or more are used for ESI and if the results are coregistered to the patient's individual MRI. Localization precision is as high as or even higher than established brain imagery techniques. HR-ESI appears to be a valuable additional imaging tool, given that larger electrode arrays are easily and rapidly applied with modern EEG equipment and that structural MRI is nearly always available for these patients.

Have all the men and women with a fragility fracture a low bone mineral density? A Nationwide Swiss Survey : FM3

Background: The prevalence of a low bone mineral density (T-score <-1 SD) in postmenopausal women with a fragility fracture may vary from 70% to less than 50%. In one study (Siris ES. Arch Intern Med. 2004;164:1108-12), the prevalence of osteoporosis was very low at 6.4%. The corresponding values in men are rarely reported. Methods: In a nationwide Swiss survey, all consecutive patients aged 50+ presenting with one or more fractures to the emergency ward, were recruited by 8 participating hospitals (University Hospitals: Basel, Bern, and Lausanne; cantonal hospitals: Fribourg, Luzern, and St Gallen; regional hospitals: Estavayer and Riaz) between 2004 and 2006. Diagnostic workup was collected for descriptive analysis. Results: 3667 consecutive patients with a fragility fracture, 2797 women (73.8 ± 11.6 years) and 870 men (70.0 ± 12.1 years), were included. DXA measurement was performed in 1152 (44%) patients. The mean of the lowest T-score values was -2.34 SD in women and -2.16 SD in men. In the 908 women, the prevalence of osteoporosis and osteopenia according to the fracture type was: sacrum (100%, 0%), rib (100%, 0%), thoracic vertebral (78%, 22%), femur trochanter (67%, 26%), pelvis (66%, 32%), lumbar vertebral (63%, 28%), femoral neck (53%, 34%), femur shaft (50%, 50%), proximal humerus (50%, 34%), distal forearm (41%, 45%), tibia proximal (41%, 31%), malleolar lateral (28%, 46%), malleolar median (13%, 47%). The corresponding percentages in the 244 men were: distal forearm (70%, 19%), rib (63%, 11%), pelvis (60%, 20%), malleolar median (60%, 32%), femur trochanter (48%, 31%), thoracic vertebral (47%, 53%), lumbar vertebral (43%, 36%), proximal humerus (40%, 43%), femoral neck (28%, 55%), tibia proximal (26%, 36%), malleolar lateral (18%, 56%). Conclusion: The probability of underlying osteoporosis or osteopenia in men and women aged 50+ who experienced a fragility fracture was beyond 75% in fractures of the sacrum, pelvis, spine, femur, proximal humerus and distal forearm. The medial and lateral malleolar fractures had the lowest predictive value in women, not in men.

Recommandations suisses romandes sur la prise en charge de l'asthme de l'adulte [Lake Geneva Region guidelines on management of adult asthma]

Asthma is a major cause of chronic morbidity throughout the world. In Switzerland, 6.9% of the adult population is suffering from asthma. The standards of treatment are unfortunately not met in most western countries, as well as in Switzerland. We put forward a complete guideline on management of adult asthma, inspired from GINA and BTS guidelines, and adapted to the specific needs of general practitioners working in french part of Switzerland. This guideline reflects a consensus between allergy, lung and emergency specialists, working in the 2 university hospitals of the Lake Geneva Region (HUG and CHUV).

Watching television: a previously unrecognized powerful trigger of λ waves.

OBJECTIVE: To assess whether lambda waves are elicited by watching television (TV) and their association with demographical and EEG features. METHODS: We retrospectively compared lambda wave occurrence in prolonged EEG monitorings of outpatients who were allowed to watch TV and in standard EEGs recorded in TV-free rooms. All EEGs were interpreted by the same two electroencephalographers. RESULTS: Of 2,072 standard EEG reports, 36 (1.7 %) mentioned lambda waves versus 46 (32.2%) of 143 prolonged EEG monitoring reports (P < 0.001). Multivariable comparison of prolonged EEG monitorings and standard EEGs disclosed that recordings performed in rooms with a TV (odds ratio, 20.6; 95% confidence interval, 4.8-88.0) and normal EEGs (odds ratio, 3.03; 95% confidence interval, 1.5-6.25) were independently associated with lambda waves. In the prolonged EEG monitoring group, all recordings with lambda waves also had positive occipital sharp transients of sleep. CONCLUSIONS: Watching TV likely represents a powerful and previously unrecognized stimulus for lambda waves. Furthermore, this study confirms the benign nature of this EEG variant and its strong association with positive occipital sharp transients of sleep.

Réduction de volume pulmonaire dans l'emphysème sévère: importance d'une prise en charge multidisciplinaire [Lung volume reduction (LVR) in severe emphysema: a multidisciplinary approach].

Most cases of emphysema are managed conservatively. However, in severe symptomatic emphysema associated with hyperinflation, lung volume reduction (LVR) may be proposed to improve dyspnea, exercice capacity, pulmonary functions, walk distance and to decrease long-term mortality. LVR may be achieved either surgically (LVRS) or endoscopically (EVLR by valves or coils) according to specific clinical criteria. Currently, the optimal approach is discussed in a multidisciplinary setting. The latter permits a personalized evaluation the patient's clinical status and allows the best possible therapeutic intervention to be proposed to the patient.

Prévalence de la prise en charge ostéopathique chez les nourrissons de1,3et6mois

Objectif : l'objectif de cette étude est de déterminer le nombre d'enfant de 0 à 6 mois de la population vaudoise ayant eu recours à l'ostéopathie, de caractériser les motivations des parents à consulter un ostéopathe pour leur enfant, d'évaluer le niveau de satisfaction d'une telle prise en charge et d'établir un profil de parents type s'il en existe un. Méthode : La méthodologie utilisée dans cette recherche prospective s'est faite au moyen d'un questionnaire accessible aux parents des sujets d'étude en format papier ou en format numérique disponible en ligne sur internet. La distribution des questionnaires s'est faite par l'intermédiaire de pédiatres installés, de sages-femmes à domicile, de mamans de jour et s'est déroulée sur une période de 3 mois à la fin de l'année 2011. Résultats : 73.3% des sujets sondés disent avoir consulté au moins une fois un ostéopathe pour leur enfant. Dans une grande majorité des cas les causes du recours à l'ostéopathie sont, d'un point de vue strictement médical, des événements fréquents et relativement banaux dans les premiers mois de vie des enfants. Beaucoup de parents consultent un ostéopathe pour effectuer un contrôle « général » de leur enfant, souvent avant même le premier rendez-vous chez leur pédiatre. Ils sont en majorité satisfaits de la manipulation et envisagent de se rendre à nouveau chez ce praticien en cas de besoin ou pour un simple contrôle du développement de leur enfant. Il ressort de cette analyse trois profils de parents : les parents n'ayant pas recours à l'ostéopathe pour leur enfant, les parents ayant recours à cette thérapie occasionnellement et les parents y ayant recours fréquemment. Ces trois profils de parents se définissent uniquement sur l'usage ou non de l'ostéopathie pour l'enfant et de sa fréquence mais ils ne sont pas influencés par les ressources financières des parents et leur propre recours à l'ostéopathie. Conclusion : Cette étude a permis de constater que le nombre de parents ayant recours à l'ostéopathie pour leur nouveau-né est important, en effet 73,3% des sujets ont été manipulé par un ostéopathe au cours de leurs six premiers mois de vie. Le contrôle précoce du nourrisson chez un ostéopathe semble rassurer les parents sur la santé de leur enfant. L'ostéopathe s'impose ainsi comme un référent supplémentaire aux soins du nourrisson, au même titre que le pédiatre.

Dix erreurs a ne pas commettre lors de la prise en charge d'une prothèse articulaire infectée en orthopédie [Ten errors to avoid while dealing with infected total joint arthroplasties].

Infections after total joint arthroplasty are rare but come with severe consequences. Timely, adequate and standardized treatment beginning at the onset of symptoms will have a major impact on the handling of this dreaded complication. In absences of clear guidelines, errors are often committed, with occasionally severe consequences for the patient. In this article, the 10 most frequent errors starting with diagnostics till antibiotic and surgical treatment will be discussed.

Sinusite aiguë: prise en charge en médecine de premier recours [Acute sinusitis]

Les infections des voies aériennes supérieures sont parmi les motifs de consultation les plus fréquents en médecine de premier recours. Lorsque la localisation est principalement rhinosinusienne, la cause est en général virale. Nous passons en revue dans cet article les conditions permettant de suspecter une origine bactérienne avec comme question centrale les critères pour l'instauration d'un traitement antibiotique. La place des examens paracliniques dans la stratégie diagnostique est discutée et en particulier celle de la radiographie standard. Rhino-sinusitis is one of the most complaint in ambulatory clinic sitting and nasal obstruction. This diagnosis is however difficult and general practitioners might overdiagnose acute bacterial sinusitis. Most imaging is not useful in determining sinusitis. Acute sinusitis is very often a self-limiting disease. Antibiotics should be prescribed only after one week of symptoms' duration and in case of the presence of two additional criteria: pain and purulent nasal discharge with nasal obstruction

Incontinence urinaire chez la femme: prise en charge en médecine de premier recours [Urinary incontinence in women: management in primary care]

Urinary incontinence in women is a largely under-evaluated problem that affects nearly one out of two adult women. Even thouh its physiopathology is complex and its etiologies are multiple (and often intricate), urodynamic investigations are not considered necessary before starting a conservative therapy, which can be initiated by the primary care physician. Conservative management is based upon lifestyle modifications, specialized physiotherapy, and in certain cases medication. In the case of insufficient response after three months, the patient should be recommended to a specialist who can evaluate the need for a surgical procedure.
