Fracture vertébrate évaluée par ostéodensitométrie. Un nouveau facteur de risque pour la fracture [Vertebral fracture assessed by DXA: a new risk factor for fracture]

At the age of 50, a woman has a lifetime risk of more than 40% to present a vertebral fracture. More than 60% of vertebral fractures remain undiagnosed. As a consequence it is of major importance to develop screening strategies to detect these fractures. Vertebral fracture assessment (VFA) by DXA allows one to detect vertebral fracture from T4 to L4 using DXA devices, while performing also during the same visit the bone mineral density measurement. Such an approach should improve the evaluation of fracture risk and therapeutic indication. Compared to the standard X-ray assessment, VFA highly enables to detect moderate or severe vertebral fractures below T6.

Vertébroplastie par voie percutanée [Percutaneous vertebroplasty]

Although vertebroplasty was initially a treatment of vertebral haemangioma or metastases, this procedure is now frequent option to the treatment of osteoporotic vertebral fractures. In this review article, we will discuss the indication, the techniques and the follow-up of the vertebroplasty. This is a risky procedure, which should be performed by experimented physicians working with high-resolution fluoroscopic equipments, by biplane fluoroscopy, to reduce the risk and irradiation to the patient. According to the available follow-up studies, there is clear evidence of a strong improvement of quality of life after vertebroplasty by rapid decreasing of back pain at least during the first six months. Other new studies will analyze the long-term follow-up after vertebroplasty.

Le médecin de famille de demain [Tomorrow's family doctor].

The profession of family doctor will undergo profound changes in the coming decade due to external, political, demographic and societal developments. Changes will also occur from within the profession affecting its content and its functioning. Other influences, in addition to generational developments (reduced working hours, feminisation, revaluation of the work-life balance), will come from collaboration with new professions, news structures as well as technical and human progress. In this transitional period it is important to uphold core values of family medicine, in particular coordination, continuity of care and the global approach to patients. In training future family doctors we must both prepare them for new skills and roles, and continue to share the core values with them.

Adaptations des recommandations pour la pratique clinique: l'exemple du Programme cantonal Diabète de Vaud [Adaptation of clinical practice guidelines--the example of cantonal Diabetes Program].

With the growing number of scientific publications, practitioners can use scientific knowledge synthesis, including Clinical Practice Guidelines (CPG). The practical use of a CPG implies considering the context, that is the local healthcare system and the patient. Thus, the CPG can never replace the expertise of the practitioner! Diabetes is a wide public health issue and the canton of Vaud established the cantonal Diabetes Program (cDP), to optimize the care of diabetic patients. The cDP has many projects including the adaptation of reliable CPG to local needs. We present the pros and cons of the CPG in the cDP and the methods to adapt it to the regional healthcare context, and also at an individual level.

Valeur ajoutée de la supervision du médecin-assistant par un médecin de famille dans une permanence [Added value of family practitioners' supervision of junior doctors in a walk-in clinic].

The pending workforce crisis in family medicine has triggered various initiatives. This article describes the PMU-FLON walk-in clinic, a project of the Institute of General Medicine University of Lausanne. The working conditions in this clinic are close to that of a family practice. Doctors in training are supervised by family doctors who work part-time in the clinic. The objective is to improve training in the various fields of family medicine, from technical skills (improving optimal use of diagnostic tools), to integrating patients' requests in a more global patient-centered approach. This new educational model allows doctors in training to benefit from the specific approaches of different trainers. It will contribute to promoting quality family medicine in the future.

Hémorragie digestive aiguë [Acute gastrointestinal bleeding]

Gastrointestinal bleeding is among the major clinical challenges for the gastroenterologists and the initial approach is very complex. For a big part of bleeding lesions, it is important to perform an endoscopic hemostatis after the introduction of an intravenous treatment (that has to be started as soon as there is a clinical suspicion of an upper gastrointestinal bleeding). The significant progresses made during the last years have allowed firstly to see the entire small bowel mucosa (video capsule) and secondly new treatments have successfully replaced surgical interventions.

Mieux connaître la médecine du travail

Les Suisses travaillent... et consultent leur médecin. La Suisse est un pays de travailleurs: un des taux de chômage les plus bas du monde (moins de 5 %), 4,4 millions de personnes actives professionnellement sur 7,5 millions d'habitants... Et, heureusement, de travailleurs sains pour la plupart: selon une enquête de 2002, 85 % des Suisses de quinze ans et plus s'estimaient en bonne santé. Malgré cela, 77 % d'entre eux avaient tout de même eu recours à un médecin dans les douze mois précédant l'enquête. Si l'on ne retient que les personnes de 15 à 64 ans (donc professionnellement actives pour la plupart), la proportion se monte même à 81 %, ce qui représente près de deux millions de personnes ayant consulté au minimum une fois dans l'année.

Préservation de la fertilité masculine et cancer [Fertility preservation and cancer in the male].

Improvement in cancer treatments resulted in an increased number of men surviving cancer. Quality of life has become an important issue in these patients. Anti cancer treatments might have transient or definitive harmful effects on male fertility. Sperm cryoconservation is currently the only proven method to preserve fertility in patients undergoing oncologic treatment. It should be proposed to every patient at reproductive age before chemotherapy, radiotherapy or any surgery involving reproductive tract. Despite low use rate, this simple method could allow patients presenting infertility after treatment to father a child.

Fièvre à répétition chez l'enfant: penser au syndrome de PFAPA [Periodic fever in children: keep in mind the PFAPA syndrome]

Les maladies autoinflammatoires font partie du diagnostic différentiel de l'état fébrile à répétition chez l’enfant. Ces maladies sont caractérisées par des poussées inflammatoires sans cause évidente. Certaines de ces maladies, comme la Fièvre méditerranéenne familiale, ont une origine génétique et nécessitent un traitement régulier pour éviter des conséquences graves à long terme. Le syndrome de PFAPA est la plus fréquente des fièvres récurrentes et son diagnostic se base sur des critères diagnostiques peu précis. Son traitement reste controversé. La prednisone en dose unique permet d'interrompre la poussée et l'amygdalectomie peut induire une rémission dans une majorité des cas. The autoinflammatory diseases should be considered in the differential diagnosis of recurrent fever in childhood. These diseases are characterized by inflammatory episodes without an evident cause. Some of these diseases, like the Familial Mediterranean Fever, have a genetic origin and need a chronic treatment to avoid severe complications on the long term. PFAPA syndrome is the most frequent cause of recurrent fever and is diagnosed based on unspecific criteria. The treatment is still controversial. One dose of Prednisone is able to interrupt the flare and tonsillectomy may induce a remission in the majority of the cases

Syndrome métabolique: syndrome fourre-tout des patients obèses ou entité spécifique? Quel traitement: hygiene de vie ou potypill [Metabolic syndrome: jumble syndrome of obesity or specific entity? Which treatment: diet or polypill?]

The reality of metabolic syndrome (MS) as a specific entity is debatable. However, the simple measure of waist circumference (>94 cm in men and >80 cm in women) is useful: (1) to check for insulin resistance by measuring serum levels of fasted glucose and insuline, cholesterol, triglycerides; (2) to look for diseases associated with MS such as hypertension, non alcohoolic steatohepatitis, sleep apnea, polycystic ovary disease, hypogonadism and to measure serum levels of ferritine, ALAT, ASAT, urate acid, CRP hs, testosterone and (3) to make obese people aware of their risk of becoming diabetic and to motivate them to change their life style. The utility of exercise and of various diets is discussed as well as the efficiency of drugs acting on different components of MS such as rimonabant, orlistat, metformin, glitazones, telmisartan and testosterone. The importance of political measures to fight the obesity epidemic is underlined.

Paralysies laryngées unilatérales [Unilateral laryngeal paralysis].

Investigations, diagnosis and treatment of laryngeal paralysis depend upon history taking and examination of phonation, swallowing and of the pharyngo-larynx. In unilateral paralysis, the main symptom is dysphonia. Dysphagia lasting more than 10 days may indicate a proximal vagus nerve lesion. Voice and swallowing therapy may be undertaken. If this remains insufficient after one month, a temporary or definitive vocal fold medialisation may be considered. Paralysis is considered to be definitive if lasting for more than 12 months. A minimal of one-year follow-up is indicated in case of idiopathic paralysis.
