[Contribution of physical and rehabilitation medicine to primary care medicine]. / Apport de la médecine physique et de réadaptation à la médecine de premier recours.

Physical and rehabilitation medicine (PRM) is an independent medical specialty, little known in Switzerland. This specialty, strongly linked to the holistic approach of the International Classification of Functioning, will be increasingly solicited by the epidemiology of disability and the imperatives of "ageing better". Its skills in prescribing human and material resources for rehabilitation provide added value in terms of loss of autonomy. Based on a biopsychosocial model, PRM has a high role to play in prevention and primary healthcare, as well as in the management and prevention of the consequences of functionally limiting diseases. There are, however, financial (pricing) and demographic (lack of representation) obstacles to effective action on behalf of the population and the healthcare system.

La médecine physique et de réadaptation (MPR), discipline indépendante, est peu connue en Suisse. Cette spécialité, liée à l'approche holistique de la classification internationale du fonctionnement, sera de plus en plus sollicitée par l'épidémiologie du handicap et les impératifs du « vieillir mieux ¼. Ses compétences de prescription des moyens humains et matériels en réadaptation apportent une plus-value sur la perte d'autonomie. Basée sur un modèle biopsychosocial, la MPR trouve sa place dans la prévention et les soins de santé primaires ainsi que dans la prise en charge et la prévention des conséquences des maladies induisant une limitation fonctionnelle. Il existe toutefois des obstacles financiers (tarification) et démographiques (insuffisance de représentation) pour une action efficace au service de la population et du système de santé.

No need for broad-spectrum empirical antibiotic coverage after surgical drainage of orthopaedic implant infections.

PURPOSE: Empirical broad-spectrum antibiotic treatment for orthopaedic implant infections after surgical lavage is common practice while awaiting microbiological results, but lacks evidence. METHODS: This was a single-centre cohort study from 1996 to 2010 with a follow-up of two years. RESULTS: We retrieved 342 implant infections and followed them up for a median of 3.5 years (61 recurred, 18%). Infected implants were arthroplasties (n = 186), different plates, nails or other osteosyntheses. The main pathogens were S. aureus (163, 49 methicillin-resistant) and coagulase-negative staphylococci (60, 45 methicillin-resistant). Median duration of empirical antibiotic coverage after surgical drainage was three days before switching to targeted therapy. Vancomycin was the most frequent initial empirical agent (147), followed by intravenous co-amoxiclav (44). Most empirical antibiotic regimens (269, 79%) proved sensitive to the causative pathogen, but were too broad in 111 episodes (32%). Cephalosporins and penicillins were used only in 44 and ten cases, respectively, although they would have covered 59% of causative pathogens identified later. Multivariate Cox regression analysis showed that neither susceptible antibiotic coverage (compared to non-susceptible; hazard ratio 0.7, 95% confidence interval 0.4-1.2) nor broad-spectrum use (hazard ratio 1.1, 0.8-1.5) changed remission rates. CONCLUSIONS: Provided that surgical drainage is performed, broad-spectrum antibiotic coverage does not enhance remission of orthopaedic implant infections during the first three days. If empirical agents are prescribed from the first day of infection, narrow-spectrum penicillins or cephalosporins can be considered to avoid unnecessary broad-spectrum antibiotic use.

[Rehabilitation after rotator cuff repair: developments and recommendations]. / Rééducation après chirurgie de la coiffe des rotateurs: développements et recommandations.

Rehabilitation post surgical repair of the rotator cuff is an important determinant of the quality of the healing process, and of the clinical and functional results. Techniques used have been reported to favor certain of those parameters at the expense of others. Several approaches have been proposed; none has reached a consensus yet. The level of evidence in the literature does not allow for definitive recommendations and elaborating a protocol relies on clinical experience as well as expert opinion, incorporating scientific data. An initial period of rest with limited passive motion emerges though as an approach suited to the treatment of most clinical situations.

[Scapular dyskinesis]. / Dyskinésie de l'omoplate.

The scapula plays a crucial role for proper shoulder function, serving as a stable base for rotator cuff activation and as a link in the kinetic chain. Joint, ligament or muscular problems near the scapula can lead to malpositions or to an altered movement pattern. This abnormal situation is called "scapular dyskinesis", which appears to be a non-specific response to a painful condition of the shoulder. The clinical examination of the scapula is crucial for every patient presenting a painful shoulder. Systematic observation and testing enable the practitioner to detect subtle static and dynamic abnormalities. Visual evaluation, objective measurements and corrective manoeuvres can evaluate the role of the "scapular dyskinesis" in the shoulder painful condition. The scapular rehabilitation will address muscular retractions and imbalances and restore a good dynamic stability, starting with analytical work, and evolving into more functional and specific exercises.

[¹¹C]acetate PET/CT visualizes skeletal muscle exercise participation, impaired function, and recovery after hip arthroplasty; first results.

PURPOSE: Based on skeletal muscle acetate physiology we aimed studying muscle function after hip arthroplasty with [(11)C]acetate PET. PROCEDURES: Two male patients were investigated 3 and 12 weeks after hip arthroplasty with muscle [(11)C]acetate PET/CT performed at rest and exercise. Median muscle SUV(mean) were calculated on three non-consecutive transverse PET slices. RESULTS: The four exercise PET/CT showed, compared with rest, consistent increase in [(11)C]acetate uptake in active muscles contralateral to surgery. On the arthroplasty side most muscles showed symmetric activity increase under exercise both at 3 and 12 weeks after surgery, but four muscles showed only minor activity increase at 3 weeks. At 3 months, functional recovery of the latter four muscles was observed. CONCLUSION: Consistent increase in [(11)C]acetate uptake in healthy muscles under exercise compared with rest was observed by PET/CT. Transiently impaired muscle function 3 weeks after surgery recovered at 3 months. These first observations merit further investigation.
